Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting structure of a side-roofing exterior panel applied to a roof, an outer wall, etc. of a building.

[0002]

2. Description of the Related Art Various types of exterior roofing panels for exteriors such as roofs and outer walls of buildings have been developed and many proposals have been made. In addition to the conventional method of roofing over the roof or outer wall of the building skeleton, a prefabricated method of laying it on a large foundation in advance on the ground or at a factory and lifting it on the building skeleton and fixing it will be performed It has become. In recent years, thatched roof structures that cover the roofs of high-rise apartment buildings and large dome-shaped thatched roof structures such as gymnasiums and exhibition halls have been widely adopted. Due to these trends, vertical and horizontal joints between prefabricated roofs at high altitudes have also become important, and there has been a demand for easier joint work and more reliable watertightness.

[0003] Conventionally, as a joining structure of a horizontal roofing panel in a horizontal direction (a direction orthogonal to a water gradient of a roof), a system in which laterally adjacent roof panels are horizontally connected by a joint fitting (for example, 56-511
44, Jpn. 2-34327, JP-A-6-33557
Etc.) are used. As the joint fitting,
A general configuration includes a plug-in cover that covers the horizontal connection portion of the roof panel from above, and a drain plate disposed below the horizontal connection portion. In general, the insertion cover attached to the draining plate is sandwiched by roof panels inserted from both sides thereof, so that the horizontal connection portion is generally water-stopped.

[0004]

However, in the above-mentioned lateral connection structure, the stability of the panel is insufficient, it is difficult to obtain sufficient watertightness under strong wind, and the construction accuracy and construction efficiency are improved. Because of the difficulty, improvement was desired. In other words, in order to seal the space between the insert cover and the roof panel in a watertight manner, the formation accuracy and construction accuracy of the insert cover and the roof panel are required, but even if the formation accuracy and the construction accuracy are secured, Deformation of the insert cover and roof panel due to strong winds and temperature differences between the cold and hot temperatures is unavoidable, and a gap is likely to be created between the insert cover and the roof panel.To secure water tightness over a long period of time, further improvement is required. I was waiting.
In addition, sandwiching the insertion cover between the roof panels on both sides of the horizontal connecting portion without any gaps was a relatively time-consuming work in the construction of the roof panels, and there was a demand to improve this workability. . Conversely, when the roof panel is completely restrained, local stress concentration occurs due to deformation factors such as a temperature difference between the temperature and the temperature, and there is a concern that partial deformation or breakage may occur. In view of this, for example, it is conceivable to provide a gap between the roof panels to allow a slight displacement of the roof panel. However, an appropriate technology that can secure the watertightness of the roof panel lateral connection portion with the gap is provided. However, since there was no such thing, a practical thing could not be realized.

[0005] By the way, in the case where equipment such as a panel-shaped solar cell module and a heating element for snow melting is mounted on a roof, in recent years,
A roof panel and an integral roof panel have been proposed. In such an integrated roof panel, it is common to connect the lower surface side of each panel through electric wiring or the like, and in particular, characteristics such as a decrease in characteristics due to water wetting. Since it is necessary to ensure sufficient waterproofness to protect the susceptible electrical wiring and the connector connecting the same, the above-mentioned securing of watertightness becomes even more important. In addition, the above-mentioned problem is not limited to the connection structure of the exterior panel on the roof, but is also common to other structures similar to the roof and the connection structure of the exterior panel on the outer wall of the building.

The present invention has been made in view of the above-mentioned problems. (A) It is possible to stably maintain watertightness over the entire horizontal connecting portion even when a strong wind or a temperature difference between the temperature and the cold acts. (B) Improve the workability of the horizontal joint, (c) Store electrical wiring and connection parts connected to equipment mounted on the exterior panel while securing sufficient waterproofness. It is an object of the present invention to provide a connection structure of a horizontal roofing exterior panel, which can improve the storage workability and the connection workability.

[0007]

According to the first aspect of the present invention, there is provided a connecting structure for a horizontal roofing exterior panel, which is formed by laterally connecting exterior panels continuously provided in a direction orthogonal to a direction of a water gradient. On the lower side of the horizontal joint of both exterior panels
A draining plate that is inclined and extends along the water gradient is disposed via a water-impermeable compressible independent foam layer, and is inserted on an upper surface side of the horizontal connecting portion to cover an upper side of the horizontal connecting portion. The connection structure of the horizontal roofing exterior panel, wherein the cover is disposed via a non-water-permeable compressible independent foam layer, and the horizontal connecting portion is sandwiched between upper and lower compressible independent foam layers. This was the solution to the problem. According to a second aspect of the present invention, in the connection structure of the horizontal roofing exterior panel according to the first aspect, the draining plate is formed by bending and forming a periphery excluding both upper and lower ends in an inclined direction, and the rising portion. A hill-shaped ridge protruding from the center of the water-receiving portion to form an upper surface along the water gradient; and a ridge-shaped ridge jointed on the hill-shaped ridge upper surface and connected laterally. And a solid porous backup material integrally joined to the lower surface of the exterior panel on both sides of the horizontal connecting portion, wherein the compressible independent foam of the draining plate is provided. A contact wall that is in contact with the layer from a lateral direction perpendicular to the water gradient is formed extending along the water gradient, and the compressible closed-cell foam is formed between contact wall surfaces on both sides facing each other at the horizontal connecting portion. It is characterized in that the body layer is sandwiched. According to a third aspect of the present invention, in the connection structure of the horizontal roofing exterior panel according to the second aspect, the hook turned up to the downstream side of the water gradient so as to rise the upstream part of the water gradient including the hill-shaped ridge of the drain board. From the water gradient upstream side, the compressible closed-cell foam is folded from the water gradient upstream side to the hook-shaped panel folded part folded back to the water gradient downstream side so as to raise the water gradient upstream part of the exterior panel. It is characterized by being engaged through a layer. According to a fourth aspect of the present invention, in the connecting structure of the horizontal roofing exterior panel according to the third aspect, the downstream portion of the exterior panel is bent downward to be engaged with the panel folded portion from the downstream side of the water gradient. At the lower edge of the found portion, a ledge turned back to the upstream of the water gradient is formed, and a downstream end of the water gradient of the drain plate is in contact with the shelf. According to a fifth aspect of the present invention, in the connection structure for a horizontal roofing exterior panel according to any one of the first to fourth aspects, the plug-in cover includes a cover main body extending along the water gradient, and the cover. The compressible independent foam layer fixed to the lower surface side of the main body along the water gradient and abutted from above on the horizontal connecting portion; and from the cover main body to both lateral sides perpendicular to the water gradient. And an extended plate-shaped skirt portion, wherein the skirt portion is urged against the upper surface of the exterior panel with a spring force against the cover main body portion and is in contact with the upper surface. According to a sixth aspect of the present invention, in the connection structure for a horizontal roofing exterior panel according to any one of the first to fifth aspects, the compressible independent foam layer on the drain board side and the compressible independent foam layer on the insertion cover side. The foam layer can be in contact with each other via a gap generated between the exterior panels on both sides of the horizontal connecting portion. The invention according to claim 7 provides the invention according to claims 1 to 6
In the connection structure of the horizontal roofing exterior panel according to any one of the above, the contact wall surface formed on the backup material on the lower surface side of the exterior panel has a groove formed along the water gradient on a side portion of the backup material. The drain board is housed between the grooves facing each other on both sides of the horizontal connecting part, and is connected to a device mounted on the exterior panel between the grooves on the lower side of the drain board. A storage space for storing the electrical wiring, piping, and the like is formed.

According to the connection structure of the horizontal roofing exterior panel according to any one of the first to seventh aspects, excellent watertightness can be obtained by sandwiching the horizontal connecting portion from above and below by the compressible independent foam layer. Even if the exterior panel is slightly deformed or displaced by a strong wind or a temperature difference between the temperature and the cold, the amount of deformation or displacement is absorbed by the deformation of the compressible independent foam layer, and watertightness is secured. The tightness between the insertion cover and the exterior panels on both sides of the horizontal joint does not ensure the watertightness of the horizontal joint, but the watertightness of the compressible independent foam layer that sandwiches the horizontal joint from above and below Therefore, displacement or the like of the exterior panel is allowed within a range where the upper and lower compressible independent foam layers are opposed to each other. Even if a gap is generated between the exterior panels, the upper and lower compressible independent foam layers maintain the sealed state of the horizontal connecting portion. According to the second aspect of the present invention, the compressible independent foam layer on the draining board is sandwiched between the contact wall surfaces formed on the backup material of the roof panel on both sides of the horizontal connecting portion, and the compressed state is maintained. Therefore, the press-contact state of the compressible independent foam layer to the lateral connection portion is efficiently ensured. According to the third aspect of the present invention, the drain panel folded portion is engaged with the panel folded portions on both sides of the water gradient upstream portion of the horizontal connecting portion from the water gradient upstream side, so that the panel folded portions on both sides are formed. The gap is
Since the watertight sealing is performed by the compressible independent foam layer, excellent watertightness can be reliably obtained even in the upstream portion of the water gradient of the horizontal connecting portion. According to the invention described in claim 4, the draining board is
The drainage folded portion of the upstream portion of the water gradient is engaged with the panel folded portion of the exterior panel, and the downstream end of the water gradient abuts on the shelf at the lower edge of the exterior panel finding portion, whereby the exterior panel is stably mounted.
At this time, the abutting state of the compressible independent foam layer on the upper surface of the hill-shaped ridge against the lower surfaces of the exterior panels on both sides of the horizontal connection portion is maintained. The downstream end of the water gradient of the draining plate is abutted on the shelf at the lower edge of the exterior panel finding portion, so that it can be stored compactly.
When the panel finding portion is engaged with the panel turning portion on the downstream side of the water gradient, the water gradient downstream end of the draining plate does not become an obstacle, so that the engagement workability is improved. Moreover, the connecting portion (vertical joint) between the exterior panels in the direction of the water gradient can be reduced in size, and the working width of the exterior panels can be effectively utilized.
According to the invention as set forth in claim 5, the hem portions on both sides of the insertion cover are urged against the upper surfaces of the exterior panels on both sides of the lateral connection portion, respectively, thereby preventing the inside of the insertion cover from being flooded. As a result, the watertightness of the horizontal joint is ensured. In addition, the hem that urges against the top surface of the exterior panel on both sides of the horizontal joint part can maintain the contact state by following the deformation and displacement of the exterior panel due to strong wind, temperature difference between cold and warm temperatures, etc. Can always be stably secured. Furthermore, since the roof panel is pressed down by the elastic biasing of the hem, the roof panel is prevented from being lifted up. According to the invention as set forth in claim 6, even if the opening width of the gap between the exterior panels on both sides of the horizontal connecting portion is expanded due to a strong wind, a difference in temperature between cold and warm, etc., the compressible independent foam layers above and below the horizontal connecting portion are connected to each other. , Excellent watertightness is stably ensured.
According to the invention described in claim 7, the storage space below the draining plate can be used for various purposes, such as a storage space for electric wiring and piping, and a work space for connection and the like. Claim 4
As described, the drainage plate folded portion of the water gradient upstream portion is engaged with the panel folded portion of the exterior panel, and the water gradient downstream end is brought into contact with the shelf at the lower edge of the exterior panel found portion, so that the exterior panel is attached to the exterior panel. With a drain plate that is stably mounted, it is easy to bring it into close contact with the lower surface of the outer panel, and it is possible to suppress the protrusion dimension to the lower side of the outer panel, so that it is easy to secure a larger storage space below that. .

However, the underlying material is not limited to this.For example, various configurations can be adopted, such as a material entirely formed of a waterproof material and separately requiring no roofing construction. is there.

FIGS. 5A and 5B are views showing the downstream portion of the water gradient of the horizontal connecting portion 2, wherein FIG. 5A is a plan view, and FIG.
It is a line sectional arrow view. 6: is a figure which shows the water gradient upstream part of the horizontal connection part 2, (a) is a top view, (b) is (a).
FIG. 5 is a sectional view taken along line CC of FIG. 4 to 6A,
As shown in (b), the roof panel 1 is provided with a roofing material 10 at the downstream end of the water gradient (eave side; lower left side in FIG. 4, left side in FIGS. 5 (a) and 5 (b)). It is provided with a finding part 5 bent downward, and a hook-shaped panel folded part 6 folded back to the downstream side of the water gradient so as to raise the upstream part (end on the ridge side) of the water gradient of the roof panel 1. I have. Finding part 5
Is a shelf 5 folded from the lower edge to the upstream side of the water gradient (ridge side).
a is formed, and can be engaged with the panel turning portion 6 from the downstream side of the water gradient. In this embodiment, the finding unit 5
And the panel turn-up portion 6 is made of a metal roofing material 10
Is formed by roll forming or pressing.

As shown in FIG. 7, the roof panel 1 is formed, for example, by attaching a clip 6a hooked on the panel folded portion 6 to a nail 6
By fixing to the base material 4 with b or a screw, it is fixed at a target position on the base material 4. The clips 6a, nails 6b, etc. function as fixing means for fixing the roof panel 1 to the base material 4. The fixing means for fixing the roof panel 1 to the base material 4 is not limited to the above-described clip 6a or the like.
For example, an end portion of the panel folded portion 6 extending to the upstream side of the water gradient is directly fixed to the base material 4 with a nail or a screw, or an adhesive provided on the lower surface side of the roof panel 1 (backup material lower surface 3a). Various configurations, such as bonding with the like, can be adopted.

As shown in FIGS. 3 and 8, on the side edge of the backup material 3, the extension 7 which is located along the side edge of the roof material 10 is left, and the other backup material 3 A groove 8 having a notch is formed. The groove 8 is
The backup portion 3 is formed so as to penetrate the backup material 3 along the water gradient, and the extending portion 7 also extends over the entire length along the water gradient of the side edge portion of the backup material 3. As shown in FIGS. 2 and 3, a drain board 11 is accommodated between the grooves 8 facing both sides of the horizontal connecting portion 2.

As shown in FIGS. 3 and 9, the extension 7 does not reach the side edge of the roofing material 10, and the side panel 1 has a thickness dimension a ( A thinner portion 10a having a smaller thickness than that of the roof panel 1 (see FIG. 9) is formed to extend over the entire length of the roof panel 1 in the water gradient direction with a constant width dimension b. Since the thin portion 10a is the roof material 10 to which the extension portion 7 has not reached, the thickness b of the thin portion 10a is the same as the thickness of the roof material 10 made of a thin metal plate. It is possible to attach the backup material 3 and the like also to the lower surface side of the thin portion 10a, but the roof panel 1
When the gap 16 between the a and 1b (specifically, the gap between the thin portions 10a of the roofing material 10) expands (normally, the roof panels 1a and 1b on both sides of the horizontal connecting portion 2 are brought into contact with each other. It is preferable that the gap 16 is linear), and a contact state between the compressible independent foam layers 11a and 12a is secured through the gap 16 (described later in detail).

At the side edge portion (tip in the protruding direction) of the extension portion 7,
A ridge 7a projecting toward the groove 8 is formed over the entire length of the extension 7 along the water gradient. The portion of the extension portion 7 other than the ridge 7a forms a recess 7b having a constant depth c over the entire length in the water gradient direction. As shown in FIG. 8, the backing material lower surface 3 a is not parallel to the roof panel 1 and is inclined to set a desired water gradient on the roof panel 1, while the extension portion 7 has a constant thickness. Because it extends along the roofing material 10 with dimensions, the groove 8
Depth d (from the lower surface of the thin portion 10a to the backup material 3)
The dimension up to the lower surface) gradually increases from the upstream side of the water gradient to the downstream side of the water gradient.

At the downstream end of the water gradient of the backup material 3,
An engagement space 9 having a shape in which a lower portion thereof is notched is formed. As shown in FIG. 4, the finding portion 5 is formed by bending and forming the downstream end of the water gradient of the plate-shaped roof panel 1 over the entire horizontal direction orthogonal to the water gradient. 9
Also, the backup member 3 is formed to extend along the entire lateral direction of the backup material 3 along the finding portion 5, and stores a shelf 5 a at the lower edge of the finding portion 5. As shown in FIG. 12, both ends of the engaging space 9 in the lateral direction communicate with the groove 8.

As shown in FIG. 4, a solar cell module 13 is attached on the upper surface of the roof panel 1. FIG.
As shown in (1), the solar cell module 13 has a configuration in which a transparent surface protective material 13b is attached on a solar cell 13a, and has a thickness t of several mm. Solar cell 1
As the layer 3a, a silicon single crystal type, a polycrystal type crystal type, or the like is employed. Surface protection material 13b
For example, a fluororesin film or a tempered glass is used. In addition, as shown in FIG.
In No. 3, a plurality of solar cells 13a are arranged in a row so as to be arranged side by side, and an internal wiring 13c is connected to an electrode (not shown) of each solar cell 13a to achieve electrical conduction.

In FIG. 4 and the like, the solar cell module 13 is attached on the flat roof panel 1, but the method of mounting the solar cell module 13 on the roof panel 1 is not limited to this. The surface protection material 13b is housed in a concave portion formed by bending the material 10 so that the surface of the surface protective material 13b is flush with the roof panel 1 other than the concave portion. Is excellent. In addition, the solar cell module 13
It is more preferable that a cooling airflow channel is provided adjacent to the lower surface of the device. Thereby, the solar cell 13a
, It can be prevented from being heated to a high temperature by irradiating sunlight, a decrease in power generation efficiency due to heating can be prevented, and power generation efficiency can be maintained. The groove 8 and the engagement space 9 described above can be used as the flow path of the airflow.

FIG. 12 shows the lower surface side of the roof panel 1.
As shown in FIG. 12, the terminal box 14 provided at the center on the lower surface side of the roof panel 1 is exposed in a groove 14 a in which the backup material 3 is cut out. Each terminal cell 14 of the solar cell module 13 is
3a are electrically connected via the internal wiring 13c, and the electric wiring 1 pulled out from the terminal box 14
When the 5a and 15b (lead wires) are connected to power distribution equipment (or power distribution equipment) (not shown), the solar cell module 13
Can be supplied to the power distribution equipment via the electric wires 15a and 15b. Electrical wiring 15
a, 15b are the upstream ends of the backup material 3 water gradient (FIG. 12)
By pulling out through the opening of the groove 14a formed on the middle upper side), it can be easily drawn into the engagement space 9 of the roof panel 1 on the upstream side of the water gradient. For this reason, the electric wires 15a and 15b can be efficiently stored without the inconvenience that the roof panel 1 rises from the base material 4 due to the electric wires 15a and 15b that have entered the lower surface of the roof panel 1. Further, since the groove 8 and the engagement space 9 communicate with each other between the roof panels 1 connected in the water gradient direction and in the horizontal direction perpendicular to the water gradient direction, the electric wiring 1
5a and 15b are inserted into the grooves 8 and the engagement spaces 9 so that the electric wiring 15 drawn out from another roof panel 1 is formed.
It is also easy to connect to a and 15b or to pull out from the roof. The electric wiring 15a, 15b
By being stored in a curved manner in the roof panel 4a, it does not hinder the construction of the roof panel 1. This also protects the electrical connection connector 15c attached to the tip.

The electric wiring 15a from the terminal box 14
The extending direction of the groove 14a from the terminal box 14 to the upstream end of the backup material 3 water gradient is substantially perpendicular to the direction in which the wiring 15b is pulled out, and therefore, when wiring or connecting work, the electrical wiring 15a, 15b The applied tensile force does not directly act on the terminal box 14, and the terminal box 1
4 is prevented. The electrical connection between the solar cell modules 13 is generally in series, but may be in parallel. Further, each solar cell 13a of the solar cell module 13 is generally connected in series by the internal wiring 13c.

As shown in FIG. 13, the draining plate 11 is
A rising portion 11b formed of a material having excellent rolling workability such as aluminum and formed by bending and forming a periphery excluding the upper and lower ends thereof in a tilt direction (water gradient direction);
A water receiving portion 11c formed on the inside of the water receiving portion 1b; a hill-shaped ridge 11d which is formed by bending and forming a central portion of the water receiving portion 11c to form an upper surface along the water gradient; and a hill-shaped ridge 11d. And a compressible independent foam layer 11a that is joined to the upper surface and abuts on the lateral connecting portion 2. In addition, a hook-shaped draining plate folded portion 11e which is turned up from the hill-shaped ridge 11d and turned to the downstream side of the water gradient is formed at the upstream portion of the draining plate 11 on the water gradient.
An extension 11f extending from the water receiving portion 11c to the upstream side of the water gradient from the draining plate turning portion 11e has a rising portion 1 on both sides.
Since 1i is formed and its protruding tip is bent upward, there is no fear of water leakage. The compressible closed-cell foam layer 11a on the hill-shaped ridge 11d is also provided on the draining plate folded portion 11e. At the downstream end of the water gradient of the draining plate 11, tongue-shaped contact pieces 11g project downward from the water receiving portions 11c on both sides of the hill-shaped ridge 11d.

The draining board 11 has a hill-like ridge 11d.
The strength is secured by this, and it exhibits excellent deformation resistance while being lightweight. In detail, the draining plate folded portion 11e is formed by bending and forming a portion extending only the flat plate portion 11h forming the flat upper surface of the hill-shaped ridge 11d, and does not form the entire hill-shaped ridge 11d. , Can be easily molded. Also, the extension 11f can be folded back into a hook shape, like the draining plate folded portion 11e, but cutting off is advantageous in that the draining plate folded portion 11e can be easily formed. At the downstream end of the water gradient of the draining plate 11, a protrusion similar to the contact piece 11g can be protruded from the hill-like ridge 11d, but a portion to be inserted into the finding portion 5 is reduced. Therefore, the connection structure between the roof panels 1 above and below the water gradient can be made small and simple,
In view of the fact that d itself is difficult to bend, it is advantageous not to protrude from the hill-shaped ridge 11d so as to correspond to the contact piece 11g.

As shown in FIG. 7 and FIG. 8, this draining plate 11 engages the draining plate folded portion 11e with the panel folded portion 6 of the roof panel 1 on both sides of the horizontal connecting portion 2 from the upstream side of the water gradient. Then, by contacting the contact pieces 11f on the shelf 5a of the finding part 5 of the roof panel 1, it is mounted on the lower surface side of the roof panel 1 on both sides of the horizontal connecting part 2. As shown in FIG. 3, the draining plates 11 are housed between the grooves 8 on the side of the backup material 3 of the roof panel 1 on both sides of the horizontal connecting portion 2,
The hill-shaped ridge 11d is housed between the backup material extending portions 7 on the side edges, and the compressible independent foam layer 11a on the upper surface of the hill-shaped ridge 11d is pressed and compressed by the horizontal connecting portion 2 from below.
Further, the compressible independent foam layer 11a includes a lower surface of the roof panel 1 on both sides of the horizontal connecting portion 2 (specifically, a lower surface of the thin-walled portion 10a of the roofing material 10) and a backup material extending portion 7 of the both roof panels 1. , And is compressed in a region surrounded by the hill-shaped ridges 11 d, thereby sealing the gap 16 between the roof panels 1 in a watertight manner.

The projecting end face of the backup material extending portion 7 functions as a contact wall surface 7c which comes into contact with the compressible independent foam layer 11a from the lateral direction perpendicular to the water gradient. Since the compressible independent foam layer 11a is sandwiched between the contact wall surfaces 7c on both sides facing each other at the horizontal connecting portion 2, the compressed state of the compressible independent foam layer 11a is maintained.
Compressible closed foam layer 11a on the lower surface of roof panel 1 on both sides
Is efficiently secured. Since the hill-shaped ridge 11d is also sandwiched between the contact wall surfaces 7c, the drainage plate 11 is positioned by this, and the horizontal connecting portion 2
Therefore, the displacement in the horizontal direction perpendicular to the water gradient is prevented. Moreover, as shown in FIGS. 5 (b) and 7, the contact piece 11g has a "U" shape with the central portion in the protruding direction bent, and is press-fitted between the lower surface of the roof panel 1 and the shelf 5a. The spring force generated by the compression and deformation is applied as a pressing force to the horizontal joint 2 of the compressible independent foam layer 11a, thereby forming the horizontal joint 2 of the compressible independent foam layer 11a. The state of pressing on is maintained stably.

As shown in FIG. 14, the insertion cover 12
A cover body 12b extending along a water gradient, which is a member formed by bending a metal plate material into a long strip shape, and fixed to the lower surface side of the cover body 12b along the water gradient and connected laterally. It has a compressible independent foam layer 12a abutting on the portion 2 from above, and a plate-like hem portion 12c extending from the cover body portion 12b to both lateral sides perpendicular to the water gradient. In addition, the insertion cover 12 is formed by bending the downstream end of the water gradient to form a hook-shaped cover finding part 12d that covers the finding part 5 of the roof panel 1 from outside.
And a cover turn-up portion 12e which is formed by turning the upstream end of the water gradient of the insertion cover 12 to the downstream side of the water gradient and protruding above the insertion cover 12.

As shown in FIGS. 7 and 8, the insertion cover 12 is provided with a cover finding portion 12d so as to cover the finding portion 5 of the roof panel 1 from the outside, and the panel of the roof panel 1 is attached. By inserting and fitting the cover folded portion 12e into the folded portion 6 from the downstream side of the water gradient, the cover folded portion 12e is stably mounted on the upper surface side of the roof panel 1 on both sides of the horizontal connecting portion 2. As a result, the compressible independent foam layer 12a is pressed and compressed by the horizontal connecting portion 2, and the contact state is stably maintained.
Is securely sealed in a watertight manner. The cover finding part 12d engages with the finding part 5 so that the shelf part 12j whose lower edge is turned back to the water gradient upstream side is overlapped below the shelf part 5a of the finding part 5 of the roof panel 1. Thereby, it is stably engaged with the finding portion 5. However, as shown in FIG. 9, the shelf 12j protrudes only from both sides in the horizontal direction perpendicular to the water gradient of the cover finding portion 12d, and is formed at the lower edge of the cover finding portion 12d in the lateral center. The cover body 12b of the insertion cover 12 on the downstream side of the water gradient is accommodated in the notch 12i.

As shown in FIG. 6B, the cover folded portion 1
2e, while being inserted and fitted into the panel turning portion 6, while being elastically deformed, climbs over the locking folding portion 6c protruding downward from the tip of the panel turning portion 6 and enters the water gradient upstream side, thereby Since it engages with the stop folding portion 6c, it is difficult to pull out the water gradient downstream side after the engagement. In addition, by applying an urging force for pressing the panel turn-up portion 6 by the cover turn-up portion 12e, a reaction force of this urging force can be made to act as a pressing force on the lateral connecting portion 2 of the insertion cover 12, The compressible independent foam layer 12a can be pressed against the horizontal connecting portion 2 with an urging force. Further, since the engagement completion can be easily recognized by the engagement sound generated when the cover folded portion 12e passes over the locking folded portion 6c, the engagement work can be reliably advanced.

As shown in FIGS. 2 and 3, the skirt 12c
Is folded on both sides of the flat plate portion 12f forming the flat upper surface of the cover main body portion 12b in a direction perpendicular to the water gradient toward the center of the lower surface of the flat plate portion 12f, and furthermore, the folded portion is interposed through the bent portion 12g. And is folded outward to extend to both sides of the cover body 12b. The compressible independent foam layer 12a is fixed so as to be sandwiched between the bent portions 12g on both sides.
It protrudes below g. The hem portion 12c is formed with a hem folded portion 12h in which a tip in a protruding direction from the cover main body portion 12b is folded toward a lower surface side.

When the insertion cover 12 is mounted on the horizontal connecting portion 2 so as to cover it from above, the compressible independent foam layer 12a projecting downward from both bent portions 12g abuts on the horizontal connecting portion 2 from above. Then, the gap 16 between the two roof panels 1 (specifically, the gap between the thin portions 10a of the roofing material 10) is hermetically sealed. Further, the bent portion 12g at the base end of both hem portions 12c and the hem folded portion 12h at the tip of both hem portions 12c are provided on the upper surface of the roof panel 1 on both sides of the horizontal connecting portion 2 (specifically, the thin portion of the roof material 10). 10a, which is the upper surface on which the solar cell module 13 is not attached).

Since the bent portion 12g is a portion bent from the flat plate portion 12f, the horizontal connecting portion 2 of the insertion cover 12 is formed.
, And is elastically deformed by a pressing force against the upper surface of the roof panel 1 by the spring force generated thereby. Both hem portions 12c are also urged on the upper surface of the roof panel 1 by the spring force generated when the hem folded portion 12h comes into contact with the upper surface of the roof panel 1 and is pushed up against the bent portion 12g. Touched. As a result, both the bent portion 12g and the hem folded portion 12h are pressed against the upper surface of the roof panel 1, so that the lower surface side of the insertion cover 12 is twice waterproof. In addition, 12g of bending parts are roof panel 1
It is also possible to adopt a configuration in which the pressing force against the roof panel 1 is concentrated only on the hem fold 12h that is in contact with the upper surface of the roof panel 1 without contacting the upper surface, thereby ensuring watertightness.

As the compressible polymer foam material which is a material of the compressible independent foam layers 11a and 12a, commercially available synthetic rubber E
Independent foam with high adaptability to the expansion and contraction of the structure.
85, manufactured by Nitto Electric Industry Co., Ltd.). This material is
It is excellent in weather resistance, cold heat resistance, and chemical resistance, and particularly has a small compressive stress, so that it is suitable in that it does not deform the structure and adapts to expansion and contraction of the structure due to a temperature difference.

As shown in FIG. 2 and FIG.
Then, the bent portion 12g of the insertion cover 12 and the hem folded portion 12h
Abuts against the upper surface of the roof panel 1 on both sides of the horizontal connecting portion 2 with a pressing force, in addition to securing water tightness,
One side of the compressible independent foam layer 11a abuts on the lower surface of the roof panel 1 and the insertable cover 12 side of the compressible independent foam layer 12a
Abuts on the upper surface of the roof panel 1 to ensure excellent watertightness.

Since the compressible independent foam layers 11a and 12a are both pressed against and abutted against the horizontal connecting portion 2, the roof panel 1 may be slightly deformed due to a temperature difference between a cold and warm temperature or a strong wind. Even if displacement occurs and the opening width of the gap 16 (separation distance between the roof panels 1) increases, the compressible independent foam layers 11a and 12a come into close contact with each other via the gap 16 and There is no change in water tightness. Even if the opening width of the gap 16 changes due to slight deformation or displacement of the roof panel 1, only the close contact between the compressible independent foam layers 11a and 12a increases or decreases, and the compressible independent foam layers 11a and 1a
Since the close contact between the 2a is maintained, there is no change in the watertightness of the lateral connecting portion 2. Specifically, the compressible independent foam layer 1
The 1a and 12a can be easily brought into close contact with each other via the gap 16 by sandwiching the thin-walled thin portion 10a having a thickness b of 2 mm or less from above and below, for example. Each of the compressed compressible independent foam layers 11a and 12a has a width dimension that is sufficiently larger than the opening width of the gap 16 of about several mm.
Therefore, even if the opening width of the gap 16 changes due to slight deformation or displacement of the roof panel 1, the compressible independent foam layer 11a, 1
The close contact portion between the 2a can be freely changed, and the watertightness of the lateral connecting portion 2 is always stably secured.

The range of variation of the opening width of the gap 16 depends on the draining board 1.
1 is set. The rising portions 11 b on both sides in the horizontal direction perpendicular to the water gradient of the draining plate 11 are provided with ridges 7 on the lower surface of the extension portion 7.
a, the movable range of the ridge 7a is set between the rising portion 11b and the hill-like ridge 11d, whereby the movable range of the roof panels 1a, 1b on both sides is set. Is set. Even if the roof panels 1 on both sides of the horizontal connecting portion 2 are to be displaced (increase the opening width of the gap 16) in a direction away from each other, the rising portion 11b and the ridge 7a
Is engaged, further displacement is regulated. vice versa,
When the roof panels 1 on both sides of the horizontal connecting portion 2 approach each other, and the hill-like ridge 11d of the draining plate 11 is sandwiched between the contact wall surfaces 7c of the backup material extending portions 7 of the both roof panels 1, furthermore. Reduction of the opening width of the gap 16 is regulated. However, in the recess 7a, a slight clearance is secured around the rising portion 11b, and inevitable displacement of the roof panel 1 due to a temperature difference between the temperature and the cold is allowed to prevent the roof panel 1 from being lifted or turned up. Is more preferable. In addition, rising part 1
It is more preferable that 1b abuts on the inner surface of the recess 7b (the lower surface of the extension portion 7) with an urging force, thereby reliably preventing water leakage from above the water receiving portion 11c to the surroundings.

As shown in FIGS. 7 and 9, between the roof panels 1 adjacent to each other on the upper and lower sides of the water gradient, the finding portion 5 of the roof panel 1 a on the upstream side of the water gradient is replaced with the roof panel 1 on the downstream side of the water gradient.
The panel folded portion 6 and the cover folded portion 12e inserted and fitted to the panel folded portion 6 from the water gradient downstream side are engaged from the water gradient downstream side. The panel turning part 6
Prevents wind and rain from blowing from the downstream side of the water gradient. Further, the inner surface of the finding portion 5 is brought into contact with the end of the panel turning portion 6, which also prevents wind and rain from being blown from the downstream side of the water gradient.
In the vicinity of the cover folded portion 12e, the concave portion 12k formed by recessing the flat plate portion 12f of the insertion cover 12 is brought into contact with the upper surface of the roof panel 1 on the downstream side of the water gradient, and the roof on the upstream side of the water gradient is placed on the concave portion 12k. Since the shelf portion 5a of the finding portion 5 of the panel 1 is placed on the lower portion, the lower edge of the finding portion 5 is covered with the cover folded portion 12e.
Even in the vicinity, it is close to the top surface of the roof panel 1 almost in the same manner as on the top surface of the roof panel 1. In addition, the finding portion 5 is bent downward from the tip of the shelf 5a and turned back to the downstream side of the water gradient.
Since “b” is arranged on the concave portion 12k, displacement of the concave portion 12k in the vertical direction of the water gradient is restricted. By the turning portion 5b turned back to the downstream side of the water gradient, the blowing of wind and rain from the downstream side of the water gradient is more efficiently prevented. In addition,
The finding part 5 is provided to avoid interference with the cover body 12b.
The vicinity of the horizontal connecting portion 5 may be cut away, and the entire return portion 5b may be in close contact with the roof panel 1 on the downstream side of the water gradient.

Drain plate 1 of roof panel 1a on the upstream side of water gradient
1 abutment piece 11g is disposed at a position where it abuts the finding part 5 of the roof panel 1a substantially from the inside, so that the panel folding part 6 and the cover folding part 12e engaged with the finding part 5 are formed. Does not interfere. For this reason, the engaging position of the finding part 5 with respect to the panel folded part 6 and the cover folded part 12e can be made as much as possible on the upstream side of the water gradient, and the overlapping dimension of the roof panels 1 connected above and below the water gradient is reduced. Shrink the roof panel 1
The working width of can be effectively utilized. As a result, there is an advantage that the light receiving area of the solar cell module 13 can be increased, and the amount of power generation can be increased. The roof panel 1 on the downstream side of the water gradient is fixed in advance by the fixing means such as the above-described clip 6a, and the roof panel 1 is newly newly added to the upstream side of the fixed roof panel 1 on the water gradient. It is common to carry out construction while connecting.

As shown in FIG. 2, in the upstream portion of the water gradient of the horizontal connecting portion 2, the panel folded portions 6 of the roof panels 1 on both sides are arranged so that the compressible independent foam layers 11a are overlapped on the upstream side of the water gradient. The gap 16a between the panel folded portions 6 (the roof on both sides of the horizontal connecting portion 2) is sandwiched between the draining plate folded portion 11e engaged with the cover folded portion 12e fitted from the water gradient downstream side. Since the panels 1 are basically brought into contact with each other, the gaps 16a are usually linear, so that excellent watertightness is ensured. For this reason, for example, during a typhoon or the like, it is possible to reliably prevent wind and rain from being blown from between the panel turnovers 6 by an airflow that blows up toward the upstream of the water gradient. On the other hand, as shown in FIG. 7 and FIG. 9, at the downstream side of the water gradient of the horizontal connecting portion 2, a gap 16 b between the finding portions 5 of the roof panels 1 on both sides (the roof panel 1 on both sides of the horizontal connecting portion 2 Because it is basically made to abut each other,
Normally, the gap 16b is linear), but is closed by the cover finder 12d engaged with the finder members 5 so that the compressible independent foam layers 12a are overlapped from the downstream side of the water gradient. Further, since the cover is also closed by the cover turn-up portion 12e engaged from the upstream side of the water gradient, the blowing of wind and rain due to the airflow from the downstream side of the water gradient to the upstream building side is reliably prevented.

As described above, according to the connection structure of the horizontal roofing exterior panel, excellent watertightness can be obtained in the entire horizontal connecting portion 2 including the upper and lower ends of the water gradient. In addition, the gap 16 formed in the horizontal connecting portion 2 is formed by a gap 16a between the panel turn-up portions 6 in the upstream portion of the water gradient and a gap 16 between the finding portions 5 in the downstream portion of the water gradient.
b, including the compressible closed-cell foam layers 11a,
2a, the watertightness is ensured, and the watertightness is secured.
Even if the opening widths of a and 16b are slightly widened, excellent watertightness can always be stably maintained.

Each of the draining plate 11 and the insertion cover 12 is engaged with the draining plate 11 and the insertion cover 12 of another adjacent horizontal connecting portion 2 or separately fixed by mounting parts. Can be mounted independently on the roof panels 1 on both sides of the horizontal connecting portion 2 without performing the mounting operation. In particular, since the draining board 11 can be installed on the base material 4 after being mounted in advance on the lower surface side of the roof panel 1, troublesome mounting work on the lower surface side of the roof panel 1 can be eliminated. In addition, since the roof panels 1 on both sides of the horizontal connecting portion 2 are positioned and held down by mounting the draining plate 11 and the insertion cover 12, for example, even if a strong wind such as a typhoon causes the roof panel 1 to float or It is possible to reliably prevent the turning over and the like. Furthermore, since the watertightness of the gap 16 can be ensured stably as described above, it is possible to absorb the dimensional tolerance of the roof itself and the roof panel 1 by the gap 16 in the work of connecting the roof panels 1 side by side. Therefore, the roof panel 1 does not need to require extremely high dimensional accuracy and construction accuracy, so that cost reduction and improvement in construction efficiency can be realized.

As shown in FIG. 7, the draining plate 11 mounted on the lower side of the horizontal connecting portion 2 is entirely inclined with a water gradient coinciding with the horizontal connecting portion 2, and Since the size of the protrusion downward from the second space can be suppressed, a sufficient volume can be secured in the storage space 17 formed below the space. For this reason, the storage space 17 can be used for storing not only the electric wires 15a and 15b but also the connectors 15c for connecting the electric wires 15a and 15b to each other and various other articles such as electric devices. Specifically, as shown in FIG. 2 and FIG. 3, when the lower surface of the draining plate 11 is set in a range of about 1 to 3 mm below the ridge 7 a at the tip of the backup material extending portion 7, the horizontal connecting portion 2 is formed. Almost the entire space formed between the grooves 8 of the backup material 3 on both sides becomes a storage space 17. Drain board 1
The upstream end of the water gradient 1 may be placed on the base material 4, but may be floated upward from the base material 4. In this case, the storage space 17 is 1, and communicates with the engagement space 9 of the roof panel 1 on the upstream side of the water gradient (see FIG. 12). Therefore, by using the engagement space 9 and the storage space 16, the electric wirings 15a and 15b can be freely wired.
Wiring workability can be improved. Hill-like ridge 11d of draining board 11
The recess formed on the lower surface side can also be used for inserting the electric wirings 15a and 15b. In the configuration in which the upstream end of the water gradient of the drain board 11 is placed on the base material 4, the recess 7 b left on both sides of the drain board 11 may be used, or the vicinity of the upstream end of the water gradient of the drain board 11 may be used. By expanding the groove 8 of the storage space 1
6 is communicated.

The water that invades the draining plate 11 may be water leaking from the horizontal connecting portion 2 or water that invades from the upstream end of the horizontal connecting portion 2 by a rising airflow. In any case, there is no leakage to the outside due to the rising portion 11b around the draining board 11, and the water is drained by the water gradient of the draining board 11. As shown in FIG. 7, the water that has flowed out of the water receiving portion 11c of the draining plate 11 drops from the contact piece 11g onto the shelf 5a of the finding portion 5, and then engages with the cover turn-back portion. The water is drained onto the roof panel 1 on the downstream side of the water gradient via the panel elongation part 12e and the panel turning part 6. Therefore, since water leakage from the draining plate 11 is reliably prevented, excellent waterproofness is obtained in the storage space 16, and there is no fear that the electric devices and the like stored therein will be flooded.

What is stored in the storage space 17 or the engagement space 9 is not limited to the electric wirings 15a and 15b connected to the solar cell module 13, and for example, a roof panel (no solar cell module is provided). An electric cable for energizing the electric heater for snow melting attached to the upper surface side or the lower surface side of), a pipe for supplying hot water for snow melting and the like can also be applied. The above is wiring and piping for equipment related to the roof itself, but wiring and piping for equipment installed on or near the roof can also be applied. For example, wiring for a television antenna, electric wiring to a roof air conditioner outdoor unit, piping for a refrigerant, and the like.

As the electric heater for melting snow, for example, a planar heating element such as a Japanese Utility Model Laid-Open No. 1-92423 is employed.
The sheet heating element of the actual open flat 1-92423 is attached to the lower surface side of the roof panel, but a sheet heating element of the same configuration is attached on the roof panel upper surface, and the upper surface is further attached. A configuration covered with a film-like surface protective material can also be adopted.
When the sheet heating element is attached on the upper surface of the roof material 10 of the roof panel 1, the mounting state is exactly the same as that of the solar cell module 13 on the roof panel 1 shown in FIG. On the other hand, when it is provided on the lower surface side of the roofing material 10, for example, a configuration is adopted in which a planar heating element is incorporated so as to be sandwiched between the roofing material 10 and the backup material 3. Regarding the planar heating element in any of the mounted states, as the electrical connector for energization, electrical continuity is ensured via electrical wiring connected to a terminal box provided on the lower surface side of the roof panel. However, roofing material 1
In general, electrical connections of a plurality of planar heating elements arranged so as to be laid along zero are parallel.

Note that the present invention is not limited to the above-described embodiment, and it goes without saying that various modifications are possible. For example, in the above-described embodiment, the application example of the roof panel on which the solar cell module and the planar heating element are mounted is shown. However, the present invention is not limited to this, and can be applied to a roof panel on which nothing is mounted. . Further, the connection structure according to the present invention is not only for the side-roofed roof exemplified in the above embodiment, but also for the connection between exterior panels in the outer wall of a building and other various structures that are inclined with a water gradient. Applicable. In the above embodiment, it is also possible to make the extended portion of the backup material reach the roof material side edge portion and cover the entire lower surface of the roof material thin portion. At this time, the thickness dimension in the vicinity of the extension of the roof panel is set to such an extent that the upper and lower compressible independent foam layers can be in close contact with each other. The compressible independent foam layer is not limited to the one fixed to the drain board or the insertion cover, and may be separate from the drain board or the insertion cover.

[0051]

As described above, according to the connection structure of the exterior panels of the present invention, the lateral connection between the exterior panels is
Excellent watertightness is ensured by being sandwiched from above and below by the compressible independent foam layers provided on the drain plate disposed on the lower side and the insert cover disposed on the upper side. Moreover, even if the outer panels on both sides of the horizontal connecting portion are deformed or displaced by a strong wind or a temperature difference between the temperature and the cold, the displacement etc.
As long as the upper and lower compressible independent foam layers are in a range facing each other, the sealed state of the horizontal connecting portion is maintained, and the watertightness can be maintained. Since the elastic deformation of the compressible independent foam layer also functions to absorb dimensional tolerances and construction errors of the exterior panel, it has an excellent effect of improving workability. According to the invention described in claim 2, the compressible independent foam layer on the drainboard side is sandwiched and compressed between the contact wall surfaces formed on the backup material of the roof panel on both sides of the horizontal joint, The pressing force of the compressible independent foam layer to the horizontal joint can be efficiently secured, and the watertightness of the horizontal joint can be more reliably ensured. According to the third aspect of the present invention, the gap between the panel turning portions on both sides is compressed by the draining plate turning portion engaged with the panel turning portions on both sides of the water gradient upstream portion of the horizontal connecting portion from the water gradient upstream side. Since the watertight sealing is performed by the water-independent foam layer, an excellent effect that excellent watertightness can be surely obtained even at the upstream portion of the water gradient of the horizontal connecting portion is exerted. According to the invention described in claim 4, the draining plate is configured such that the draining plate folded portion of the upstream portion of the water gradient is engaged with the panel folded portion of the exterior panel, and the downstream end of the water gradient is located on the shelf at the lower edge of the exterior panel finding portion. Can be stably mounted on the target exterior panel without the need for a separate mounting configuration, so that it can be installed together with this exterior panel after mounting on the exterior panel, and the bottom surface of the exterior panel It has an excellent effect that the workability of mounting on the side can be improved. In addition, the pressing force of the compressible independent foam layer on the hill-shaped ridge below the horizontal joint is secured, and the water between the exterior panels is reduced by making the fit of the water gradient downstream end of the drain board to the exterior panel found part compact. There is also an advantage that downsizing of the connection portion (vertical joint portion) in the gradient direction can be easily realized. According to the invention as set forth in claim 5, the hem extending from both sides of the insertion cover is urged against the upper surfaces of the outer panels on both sides of the horizontal connecting portion to contact with each other. Even if the exterior panel is deformed or displaced, an excellent effect is obtained in that the abutting state of the skirt portion on the exterior panel upper surface is stably maintained, and watertightness can always be stably secured. According to the invention as set forth in claim 6, even if the opening width of the gap between the exterior panels on both sides of the horizontal connecting portion fluctuates due to the deformation or displacement of the external panel, the compressible independent foam layers above and below the horizontal connecting portion are connected to each other. Are in close contact with each other via the gap, and the gap is closed, and an excellent effect of stably maintaining excellent watertightness at the lateral connecting portion is exhibited. According to the invention of claim 7, there is provided an excellent effect that the storage space below the draining plate can be effectively used for various purposes such as a storage space for electric wiring and piping, a work space for connection, and the like. Play. Moreover, as described in claim 4, when the draining plate itself is configured to be attached to the target exterior panel independently, the draining plate housed between the grooves on the side of the backup material of the exterior panel on both sides of the horizontal connecting portion can be used. In order to press the upper compressible closed-cell foam layer from below on the horizontal joint portion, the upper compressible closed-cell foam layer is stored in the upper portion between the grooves, so that it is possible to obtain a storage space penetrating the exterior panel in the water gradient direction. In addition, the present invention has an excellent effect that the wiring of electric wiring and piping is free.
