DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a valley tile slippage prevention device, and more particularly to a valley tile slippage prevention device, which can prevent corrosion of a valley gutter.
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a valley tile slippage prevention device that can also prevent clogging of valley gutters with garbage and damage to birds on the back side of valley tiles.

[0002]

2. Description of the Related Art Generally, when a valley is formed in a roof shape,
At the bottom of the valley, there is provided a valley gutter for collecting rainwater flowing from the roofs on both sides and guiding it to the gutter below. If the valley-shaped roof is tiled, so-called valley tiles forming the eaves on both sides of the roof are provided at an appropriate interval from each other, and the valley gutter is located below the interval. As this valley roof tile, a dedicated roof tile may be used, but in many cases, a usual cross tile is cut into a required size at the site and used.

FIG. 8 and FIG. 9 show an example of a valley-shaped tiled roof. In the figure, reference numerals 3 and 3 'denote tiled roofs that form a valley with each other, and valley tiles 5 and 5' that form the eaves.
(In FIG. 8, the left valley tile 5 is shown in a state where most of the valley roof tile 5 is removed.) The tip of the valley roof tile 5 is cut with a cutting tool such as a grinder so that a required interval W is opened therebetween.
Processed so that they are parallel to each other.

A valley gutter 1 is provided at a valley bottom formed at the bottom of the left and right roofs 3 and 3 '. The valley gutter 1 has a flat V-shaped bottom portion 1a, side walls 1b rising from both left and right ends of the bottom portion 1a, and flanges 1c projecting from the upper end of the side wall 1b to opposite sides. As a material of such a valley gutter 1, a metal plate having good rust resistance and easy to bend is used, and a stainless steel plate is sometimes used. In general, a “copper plate” is used. Code 7
Indicates a draining bar struck on the field board 9. Valley 1
Is fixed to the field board 9 with its flange 1c inserted between the draining bar 7 and the roof tiles 5, 5 '. The protruding dimension L from which the valley roof tiles 5 and 5 'protrude from the draining bar 7 (see FIG. 9).
Is generally set to about 100 millimeters in order to secure the rain.

The valley gutter 1 is provided in a plurality of connected shapes as needed according to the length of the valley at the site (FIG. 8 shows an example in which two are connected). And the lower end of valley gutter 1 is horizontal gutter 1
Folded to face 1. The rainwater that has fallen on the left and right roofs 3 and 3 ′ falls into the valley gutter 1, is collected, and then falls to the vertical gutter (not shown) via the horizontal gutter 11.

[0006]

There are various problems with such a valley structure in a tiled roof. One of them is
The valley tiles 5 and 5 'are very unstable and easily slip off. In other words, the valley roof tiles 5 and 5 'are cut so that their lower ends are aligned, so that they are rarely left in a manufactured shape, and in many cases, the shape is considerably reduced. As a result, the dimension L of the valley roof tiles 5 and 5 ′ protruding from the drainage bar 7 becomes longer for the size thereof, and the portion projecting forward from the portion remaining behind the drainage bar 7 becomes longer. Is not uncommon. Such a state is very unstable, and may be easily shifted or fall into the valley 1 even by a small vibration. In some cases, this displacement may be sufficient only with the valley roof tiles 5 and 5 ′, but in some cases, the valley roof tiles 5 and 5 ′ may be displaced by upper tiles.

Conventionally, in order to prevent such displacement of the valley roof tiles 5 and 5 ′, it is conventionally necessary to wire the valley roof tiles 5 and 5 ′ or to insert a rubber material between the roof tiles 5 and 5 ′. Has been done. However, the effect of the wire hooking immediately lost its effect because the wire rusted, and the effect was hardly expected because the rubber material was not mechanically fixed. In addition, the protrusion dimension L of the valley roof tiles 5 and 5 'cannot be reduced in any way in order to secure the rain.

On the other hand, the valley 1 has problems in durability and replacement work. The rainwater that has fallen on the left and right roofs 3 and 3 ′ gathers for each valley line of each row of tiles, flows there, and falls on the valley gutter 1. Therefore, the corrosion of the bottom surface 1 a of the valley gutter 1 is caused by the position where the rainwater falls. And proceeded locally, and sometime a hole was made here. The number of years until the hole becomes clear depends on the material quality, environment, etc. of the valley gutter 1, but it is empirically found that the valley gutter 1
Is less than 15 to 20 years after construction. This hole naturally wets the base plate 9 and causes rain to leak into the room.

The work to replace the valley gutter 1 is performed by
8 is completely removed as in the case of the roof 3 on the left side in FIG. 8, and then the valley gutter 1 is replaced with a new one. Repair is also performed, and finally, the valley roof tiles 5 and 5 'that have been removed must be re-roofed. For this reason, despite the fact that only the troughs 1 are replaced, this work becomes a large work that requires extra labor and costs.

The valley gutter 1 is liable to be clogged with dead leaves and debris that have flown, and the backside of the valley roof tiles 5 and 5 ′ is a suitable habitat for birds such as sparrows. It is not uncommon for food, food debris, feces, and the like to clog the valley gutter 1, the horizontal gutter 11, and the like. And, when a dedicated one is not used for the valley roof tiles 5 and 5 ', the cut-out kerchief becomes a full view, and this kerchimer usually has a different color from the surface of the valley roof tiles 5 and 5'. Therefore, there was a problem that the appearance was very bad.

The present invention has been made in view of the above-mentioned conventional problems, and it is possible to substantially surely prevent a valley tile from slipping off and to significantly suppress the progress of corrosion of a valley gutter due to rainwater. An object of the present invention is to provide a device for preventing falling down of a tile. Further, the present invention provides a valley tile slippage prevention device which not only can prevent the valley roof from slipping off and the valley gutter corrosion due to rainwater, but also can effectively prevent dust from entering the valley gutter. The purpose is to do.

[0012]

In order to achieve this object, a valley tile displacement prevention device according to claim 1 is provided with left and right holding plates having a holding wall in contact with the valley tile, and a left and right holding plate. Coupling means for coupling the plates while facing each other and pressing the left and right pressing plates toward opposite sides;
The holding wall of the holding plate is provided with a large number of water holes formed in a state of being arranged in the longitudinal direction.

Therefore, the left and right holding plates are arranged so that their holding walls are respectively in contact with the tips of the left and right valley tiles, and the left and right holding plates are connected to each other by connecting means. If the right and left pressing plates are pressed to the opposite sides, the left and right valley tiles will stick to each other with the present device interposed therebetween. In addition, rainwater that fell on the roofs on both sides passed through the water holes formed in the holding wall,
Alternatively, it falls into the valley gutter through the gap between the holding wall and the valley tile, so that there is no problem in guiding rainwater. In addition, when this rainwater falls on the valley gutter, it is dispersed in multiple water holes or in the gap between the valley roof tile and the holding wall, and is concentrated at least at the valley line of the valley roof tile. Since it does not fall into the gutter, the progress of corrosion as the hole becomes clearer in the valley gutter can be considerably suppressed.

Further, since the opening surface of the back side space of the valley tile is closed by the holding wall of the holding plate, the size of the water passage hole can be selected without obstructing the guide of the rainwater. Birds such as sparrows can be reliably prevented from entering the back space. Even when a normal roof tile is cut and used as a valley roof tile, the cut edge is mostly hidden by the holding wall, so that the appearance is improved.

According to a second aspect of the present invention, in the valley tile slippage prevention device according to the first aspect, the connecting means is constituted by a bolt and nut assembly. Specifically, for example, the head of the bolt is rotatably supported by one of the holding plates, and a nut is supported by the other holding plate, and the bolt is screwed to the nut. With this configuration, the left and right holding plates can be firmly connected to each other by the bolt and nut assembly, and the distance between the left and right holding plates can be freely adjusted by rotating the bolt relative to the nut, and
They can be pressed to opposite sides.

According to a third aspect of the present invention, there is provided the valley tile slippage prevention device according to the second aspect, wherein a coupling portion coupled to the left and right holding plates via a bolt and nut assembly is provided, and the coupling portion is provided with a bolt and nut. It is provided with a bolt passage groove through which a set of bolts passes in the radial direction. With this configuration, the work of attaching the bolt and nut assembly to the holding plate can be performed in the radial direction, that is, in the direction orthogonal to the axis of the bolt, so that the on-site assembly can be performed easily and quickly.

According to a fourth aspect of the present invention, in any one of the valley tile slippage prevention devices according to the first to third aspects, a lid that is fixed to the left and right holding plates to close the upper surface of the inner space of these holding plates. It is provided with members. Therefore, it is possible to substantially surely prevent dust and birds from entering the valley gutter, and at least the cover plate can be covered and concealed from above. Strength is also increased.

According to a fifth aspect of the present invention, in the valley tile slippage prevention device according to the fourth aspect, a closing wall for closing most of the inclined lower end openings of the inner spaces of the left and right holding plates at the tip of the lid member. Is provided. This makes it possible to more reliably prevent dust, birds, and the like from entering the valley gutter, so that the so-called blindfold can be made, and the appearance becomes very good.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A valley tile slippage prevention device 21 according to an embodiment of the present invention will be described below with reference to the drawings.
The valley tile slippage prevention device 21 includes a main body 23 and a lid 25. The main body 23 includes a holding plate 27 and the holding plate 27.
And a nut-and-nut assembly 29 for connecting the left and right two pieces so as to be parallel to each other, a coupling bracket 31 fixed to the presser plate 27 and forming a joint portion of the bolt and nut assembly 29, and a presser plate as necessary. It is composed of a connecting plate 33 for connecting the 27 in a cascade.

The holding plate 27 is formed of a stainless steel plate material having a thickness of about 1.5 mm, and has a long strip-shaped holding wall 35 which forms a main part thereof. Narrow feet 37 extending along side edges
And a slightly wide lid attachment piece 39 extending along the upper edge of the holding wall 35. The foot piece 37 is provided in a posture having a substantially right angle between the foot piece 37 and the holding wall 35. Lid mounting piece 3
9 protrudes to the same side as the foot piece 37,
5 is provided in a posture having an opening angle of approximately 110 °.

A large number of water holes 41 (see FIG. 4 and the like) are formed in the holding wall 35 at a constant arrangement pitch in the longitudinal direction in a region where both ends are left. The water passage hole 41 has a substantially I-shape of alphabetic characters, the width of each part is set to about 15 mm, and the arrangement pitch is set to about 40 mm. In addition, two connecting holes 43 (see FIG. 4) are formed at both ends of the holding wall 35, two at the top and two at the bottom. The lid mounting piece 39 is formed with seven lid mounting holes 45 arranged at regular intervals in the longitudinal direction, and the lid mounting hole 45 is a long hole elongated in the width direction of the lid mounting piece 39. .

A pair of bracket mounting holes 47 (see FIGS. 4 and 6) located on both sides of the water passage hole 41 are formed in the holding wall 35 at four locations. These four locations correspond to the four odd-numbered ones counted from the ends of the seven lid mounting holes 45, respectively.

The coupling bracket 31 (see FIG. 7 and the like) has a bolt engaging portion 51 bent in a U-shape as viewed from above, and mounting portions 53 extending from both ends of the bolt engaging portion 51 to opposite sides. An attachment hole 53 a is provided in the center of the attachment portion 53. A substantially U-shaped bolt passage groove 55 is formed at the center of the intermediate piece 51a of the bolt engaging portion 51, and the bolt passage groove 55 has substantially the same dimensions as the thickness of a shaft portion of a bolt and nut assembly 29 described later. And one end thereof reaches the upper end edge of the intermediate piece 51a. Such a coupling bracket 31 is also formed of a stainless steel plate.

The four connection brackets 31 are attached to the holding wall 35 of the holding plate 27 at a time. That is, as shown in FIGS. 4 and 5, the coupling bracket 31 has the mounting portion 53 overlapping the side surface of the pressing wall 35 opposite to the direction in which the foot piece 37 and the lid mounting piece 39 protrude. The mounting hole 53
A bolt 57 is passed through a and the bracket mounting hole 47, and a nut 59 is mounted on the bolt 57 to be fixed to the holding plate 27.

The bolt and nut assembly 29 includes one bolt 6
1 and three nuts 63, 65, 67. The connection of the holding plate 27 by the bolt and nut assembly 29 is performed, for example, as follows. First, the two holding plates 27 to which the connecting brackets 31 have been attached are placed in a posture substantially parallel to each other, and the three nuts 63 and 6 of the bolt and nut assembly 29 are set.
5 and 67 are attached to the bolt 61 in advance. In this case, one nut 63 is screwed close to the head 61a of the bolt 61 as shown in FIG. 4, and the other two nuts 65 and 67 are attached around the tip of the bolt 61 with a slight gap. Keep it.

From this state, a portion of the bolt 61 between the head portion 61a and the nut 63 near the head portion is engaged with the bolt passage groove 55 of the coupling bracket 31 attached to the one holding plate 27. Then, the nut 63 is fastened to the head 61a of the bolt 61. As a result, the head 61a of the bolt 61 and the nut 63 tighten the intermediate piece 51a of the coupling bracket 31, so that the bolt 61
Is fixed to one of the holding plates 27. Next, a portion of the bolt 61 between the other two nuts 65 and 67 is engaged with the bolt passage groove 55 of the coupling bracket 31 attached to the other holding plate 27,
The two nuts 65 and 57 are tightened together. As a result, the two nuts 65 and 67 fasten the intermediate piece 51a of the coupling bracket 31, so that the tip of the bolt 61 is fixed to the other holding plate 27.

In this way, the two right and left holding plates 27 are joined in a posture substantially parallel to each other. In this state, the distance between the right and left holding plates 27 is two nuts 6
It can be adjusted by changing the positions of 5, 67. That is, if the nuts 65 and 67 are moved to the head 61a side of the bolt 61 in a state where the nuts 65 and 67 are loosened, the interval is reduced, and if the nuts 65 and 67 are moved to the tip side of the bolt 61, The spacing increases.

The connecting plate 33 (see FIGS. 4 and 6) is also formed of a stainless steel plate, and has a similar shape when viewed from the front-back direction slightly smaller than the shape when viewed from the longitudinal direction of the holding plate 27. Four bolt holes 69 are formed in the rectangular plate-shaped main part.

When connecting the holding plates 27 in a column, the connecting plate 33 is used. As shown in FIG. 6, this connection is made from outside (pressing wall 35) so that the front half and the rear half of connecting plate 33 are crotched at the ends of two pressing plates 27.
(In such a manner that the connection plate 33 is accommodated in a concave space formed by the foot piece 37 and the lid attachment piece 39). This fixing is performed by passing a bolt 71 through the connection hole 43 provided at both ends of the holding plate 27 and a bolt through hole 69 of the connection plate 33, and attaching a nut 73 to the bolt 71. Since the holding plates 27 are connected in a tandem manner in this manner, no step is formed on the outer surface of the connecting portion, as can be seen from FIG.

The lid 25 is formed by sheet metal processing of a baked colored tin. The lid 25 has a closing wall 75 and a type 25A,
There are two types, 25B, which do not have this. The portion excluding the closing wall 75 has a length (about 90 mm) that is approximately half the longitudinal dimension of the holding plate 27, and is bent in the middle in the width direction. Thereby, the shape as viewed from the longitudinal direction is formed so as to form a flat inverted V-shape.
The bent angle of the inverted V-shape is substantially the same as the angle formed by the lid attachment pieces 39 of the holding plates 27 and 27 that are joined to the left and right.

One end of the lid 25A is approximately 90
A notch 77 having a shape opened at an angle of 0 ° is provided, and a closing wall 75 protrudes downward from an edge of the notch 77.

The members of the valley tile slippage prevention device 21 are configured as described above, and several types of the holding plates 27 having different heights and different lengths are prepared. In accordance with this, several types of connection plates 33 having different height dimensions and bolt / nut combinations 29 having different shaft lengths are prepared.

Next, the operation of installing the valley tile slippage prevention device 21 and the operation of the device 21 will be described (FIG. 3).
Etc.). As the holding plate 27 to be used, the roof 3,
In the 3 ', a size corresponding to the interval W between the valley roof tiles 5 and 5', the length of the valley, etc. is selected, and a required number is prepared. The holding bracket 27 is previously provided with the connecting bracket 31 by the method described above. Install it. Then, a required number of bolt and nut assemblies 29 of a size corresponding to the selected holding plate 27 are prepared, and these are raised on the roof of the site.

First, the troughs 1 are arranged in such a manner that the holding plates 27 are arranged in two rows.
Put on. In this case, the posture of the holding plate 27 is
It is preferable that the connecting brackets 31 be placed on the valley gutter 1 so that the connecting brackets 31 face inward with each other and lean on the valley roof tiles 5 and 5 ′. When it is necessary to connect the presser plates 27 in a column, they are connected by a connecting plate 33. However, this connection may be processed before being put on the roof. Then, the left and right holding plates 27 thus arranged are connected to each other using the bolt and nut assembly 29 as described above (this connection may be pre-processed before being raised on the roof, but in this case, It is preferable that the interval between the right and left holding plates 27 is set to be somewhat smaller than the interval between the valley tiles.) In this case, the nut 63 is fastened to the head 61a of the bolt 61, but the other two nuts 65 and 67 are not fastened.

Thus, as shown in FIG.
Is assembled between the left and right valley roof tiles 5 and 5 ′ on the valley gutter 1, and the valley roof tiles 5 and 5 ′ face a substantially intermediate portion in the height direction of the holding wall 35 of the holding plate 27 (FIG. 3). From this state, the nut 65 is moved to the right to
Are pressed against each other, and the pressing wall 35 is pressed against the tip of the valley tile. It is desirable that the operation of moving the nut 65 be carried out a little at a time for all the bolt and nut assemblies 29 so that the pressing of the pressing wall 35 against the valley tiles 5 and 5 'is uniform. After the left and right holding plates 27 are pressed against the valley tiles 5 and 5 'in this manner, the nut 67 is tightened to the nut 65 to fix the gap between the left and right holding plates 27.

However, the rows of the left and right valley roof tiles 5 and 5 'are stuck to each other with the main body 23 interposed therebetween, so that they do not easily slip off even when subjected to a considerably strong vibration.
Then, when the main body 23 is installed in this way, as shown in FIG.
5 is located so as to face the water passage hole 41 formed therein. Therefore, part of the rainwater that has fallen on the roofs 3 and 3 ′ on both sides falls into the valley gutter 1 through the numerous water holes 41, and another part of the rainwater falls between the holding wall 35 and the valley tiles 5 and 5 ′. It falls into the valley gutter 1 through the gap between them. In this state, the opening surface of the back space 79 of the valley roof tiles 5 and 5 ′ is closed by the lower end of the press wall 35 of the press plate 27, and the normal roof tile is cut and used as the valley roof tile. Even if it does, the cut edge is mostly hidden by the holding wall 35.

The lids 25A and 25B are attached to the lid attachment pieces 39 of the right and left holding plates 27 so as to cover the lids. In this case, as shown in FIG. 1, one lid 25A having a closing wall 75 is provided at the lower end of the valley, and another lid 25B is provided in a number corresponding to the total length of the state in which the presser plate 27 is connected. Lid 25
A and 25B are attached, for example, as follows. First, the lids 25A and 25B are placed on the right and left holding plates 27 so as to be placed on the crotch while being positioned, and marked at a position corresponding to the lid mounting hole 45 formed in the lid mounting piece 39. Bolt through hole 81 using a tool such as an electric drill
(See FIG. 6). Then, the lids 25A and 25B again
Is put on the holding plate 27, a bolt 83 is passed through the lid mounting hole 45 and the bolt through hole 81 from below, and a nut 85 is mounted on the bolt 83.

The work of attaching the lids 25A and 25B starts from the lower end of the valley (25A) and proceeds upward in order, and the front end of the rear-order lid is appropriately positioned at the rear end of the front-order lid. Layer on. The lid 25A is attached so that the closing wall 75 closes the lower opening of the inner space of the left and right pressing plates 27. Thus, the upper surface of the inner space of the left and right holding plates 27 is closed, and the opening at the lower end of the inclined space is also closed by the closing wall 75.
The main body 23 is completely covered by the lids 25A and 25B at least when viewed from above.

As described above, since there is no step on the outer surface at the connecting portion of the holding plates 27, the lids 25A and 25B are attached to the holding plate 27 in a state where there is no gap between the holding plates 27. And therefore the lids 25A and 25A
There is no case where the overlapping portion of B is greatly floated.

Although the embodiment of the present invention has been described in detail above, the specific configuration is not limited to this embodiment, and there are changes in the design without departing from the gist of the present invention. Are also included in the present invention. For example, the connecting means in the present invention has a function capable of connecting the pressing plates arranged on the left and right while facing each other and pressing the left and right pressing plates toward opposite sides. However, the present invention is not limited to the bolt and nut assembly shown in the embodiment.

Also, the valley tiles to be targeted by the valley tile slippage prevention device according to the present invention are not limited to those obtained by cutting ordinary tiles, and are manufactured in advance as dedicated ones. Even valley tiles can be targeted. The shape of the holding plate is not limited to the shape shown in the embodiment. For example, the width of the foot may be increased so as to be stably seated on the valley gutter. It is conceivable to extend the gutter near the side wall to contribute to the rain.

[0042]

As described above, in the valley tile slippage prevention device according to the first aspect, since the left and right valley tiles are in contact with each other across the present device, they are subjected to a considerably strong vibration. However, it does not easily slip off, and the rainwater that has fallen on the roofs on both sides falls into the valley gutter through the water holes formed in the holding plate, so that there is no hindrance to the rainwater guide. There is no. In addition, when this rainwater falls into the valley gutter, it is dispersed into multiple water holes,
Since it is dispersed also in the gap between the valley roof tile and the holding wall and does not fall into the valley gutter at least at each valley line of the valley roof tile, the progress of corrosion of the valley gutter can be greatly reduced. And since the face and mouth surface of the back space of the valley tile are closed by the holding wall of the holding plate, without obstructing the guide of rainwater,
Birds such as sparrows can surely be prevented from entering the space behind the valley tile, and the cut-off woodcut of the valley tile is mostly hidden by the holding plate, so that the appearance is improved.

According to the second aspect of the present invention, the left and right holding plates can be firmly connected to each other by the bolt and nut assembly, and the distance between the left and right holding plates can be freely adjusted by rotating the bolt with respect to the nut. In addition, they can be pressed to opposite sides.

According to the third aspect of the present invention, the operation of attaching the bolt and nut assembly to the holding plate is performed in the radial direction,
Because it can be done from the direction perpendicular to the axis of the bolt,
On-site assembly can be performed easily and quickly.

According to the fourth aspect of the present invention, dust and birds can be almost certainly prevented from entering the trough and the holding plate can be concealed from at least from above, so that the appearance can be further reduced. Thus, the strength of the left and right holding plates is also increased by the lid member.

According to the fifth aspect of the present invention, dust and birds can be more reliably prevented from entering the valley gutter, and the so-called concealed nose can be formed, so that the appearance can be greatly improved.
