Description

  The present invention relates to a roofing material for side walls widely used in general houses, offices, condominiums, welfare facilities, resort facilities, commercial facilities, public facilities, and the like, and a connection structure of the roof materials.

  It is common to use roofing materials that have a rectangular shape that is relatively long in the direction of the wife and short in the direction of the eaves and the ridge. It can be picked up by repeating the process sequentially.

  Conventionally, as roofing materials used for horizontal roofs, joints such as goby are provided at the left and right ends and upper and lower ends, respectively, and adjacent roofing materials are vertically moved (eaves, ridge direction) using these joints. ), Left and right (wife direction).

  As a prior art regarding this point, one disclosed in Patent Document 1 is known.

Japanese Patent No. 4131567 Japanese Patent No. 2857665

  By the way, the conventional roof material currently disclosed by the above-mentioned patent document 1 has the troubles described below.

  In other words, when connecting the roofing material to the left and right (in the direction of the wife), the conventional roofing material engages the upper goby folded downward and the lower goby folded upward. Since it has a structure in which it is hooked and connected, strict control of dimensional accuracy is required for its production, and efficient production is difficult.

  In addition, in order to form the seam hanging portion, it is necessary to fold back the roofing material a plurality of times, and the weight of the roofing material is increased by the length, and an increase in cost is inevitable.

  Furthermore, when lifting the roof, it is necessary to carry out a haze work in the left-right direction, which requires a lot of work time, and the connection form of the roof material is, for example, stepped or In the case of changing to a flat type, there is a disadvantage that a roof material provided with a joint corresponding to the flat type must be prepared separately.

  In this type of roofing material, it may be required to install a snow stop fitting, but conventional roofing materials are usually molded from a single plate using thin steel plates. In addition, even if it is fixed to the roof material main body by a fastening means such as a screw, sufficient mounting strength cannot be ensured, which makes it unsuitable for mounting a snow stopper.

  As a conventional technology related to the mounting structure of the snow stop bracket, the bracket mounting portion is processed according to the shape of the fitting portion (lower fitting portion) located on the ridge side of the roof material, and this is applied to the field board and rafter. A device disclosed in Patent Document 2 that is fixed with a plurality of nails or screws is known.

  However, in the conventional structure for attaching a snow stopper, when the attachment portion is fixed to a narrow rafter having a width of about 30 to 40 mm, for example, the rafter is covered with asphalt roofing or a field plate. Therefore, the position cannot be accurately grasped, and the rafter may come off and be fixed only to the field plate, and may be attached in an unstable state.

  In addition, since the conventional mounting part of the snow stopper is located inside the roofing material, in order to install it, it is necessary to install it simultaneously with the construction of the roof (it cannot be retrofitted), and the construction of the roof Sometimes it is indispensable to determine the installation location and quantity in advance, and to prepare snow stoppers accordingly.

  Accordingly, an object of the present invention is to efficiently connect the roofing material in the left-right direction (wife direction) without causing deterioration of waterproofing, for the connecting structure of the roofing material for the side and the roofing material for the side. The connection form is easily changed, and the snow stopper is securely attached under a relatively simple work regardless of before and after the construction of the roof.

The present invention comprises a rectangular roofing material body having a pair of left and right short sides and a pair of long sides sandwiching each short side up and down, with the short sides facing the wife direction. The roof of the building structure is strung by connecting the long side part to the long side part of the roofing material arranged adjacent to each other from the eaves to the ridge. I'll give you a roofing roofing material
The roof material body is folded in an S shape or an inverted S shape toward the short side portion over the entire area between the long side portions to form a step on the outer surface of the roof material body. The long side portion of the long side portion, which is located on the ridge side of the long side portion, is provided with a lower goby that fits on the upper goby of the roofing material that is adjacently disposed immediately above the long side portion, Among them, the long side located on the eave side is provided with an upper goby that fits on the lower goze of the roof material adjacently disposed immediately below, and one of the pair of short sides is provided with the roof material main body. While forming a stepped portion between the outer surface and the eaves, providing a lower joint formed with irregularities extending along the ridge direction, the other short side of the pair of short sides, An upper joint that overlaps the lower joint of the roofing material disposed adjacent to the upper joint is provided, and the upper joint is provided on the side of the stepped-down portion. An abutting portion that forms a flat connecting portion with the roof material that is adjacently disposed by contact with a surface; and a roof material that is adjacently disposed by contact with the outer surface of the roof body. A roofing material for a horizontal roof, characterized in that a back grounding portion for forming a connecting portion with a step is provided between them.

In the roofing material for the horizontal roof having the above-described configuration,

It is composed of a folded piece and a fixed piece that connects to the end of the second folded section and is connected to the roof base material to fix and hold the roof material body, and is open to the upper goby toward the ridge side. A concave portion is formed, and a folded portion that fits into the concave portion formed in the first folded portion of the lower goby is provided, and a developed length equivalent to the concave and convex portions of the lower joint is provided at the edge in the width direction of the lower goze. Providing irregularities having,
2) The upper goby folding part consists of a vertical wall connected to the roof material body and forming a small edge of the roof, and a horizontal wall connected to the lower end of this vertical wall and turned back toward the ridge side, and the width of the upper goby In the edge of the direction, the concave portion is formed by pushing the vertical wall inward, and a stepped-down portion connected to the stepped-down portion of the lower joint is provided.
3) Affixing insulation on the back of the roofing material body,
Is preferable as a specific means for solving the problems of the present invention.

  Further, the present invention provides a connection structure in which the roof of a building structure is lifted using the side roofing material having the above-described configuration, and the upper joint of another roofing material body disposed adjacent to the lower joint is overlapped. The lower goby and the upper goby are respectively fitted to the lower goze and upper goze of another adjacent roof material to connect the main body of the roof material along the wife direction. The upper goby of another roofing material that is adjacently disposed immediately above it is fitted to the upper goby of the other roofing material that is adjacently disposed immediately below it. A snow stop fitting connected to the ridge direction and connected to and fixed to the second folded portion of the lower goby on which the folding portion is located is provided on the outer surface of the roof material main body. It is a connecting structure of roofing material for the side.

In the connecting structure of the roofing material for the horizontal roof having the above configuration,
1) The snow stopper fitting is fixed and held via a fastening means directly linked to the second folded portion of the lower goby, and the main body portion (the lower neck portion) of the fastening means is attached to the second folded portion. Storing in the recess,
2) A snow stop fitting is fixed and held via fastening means that penetrates an upper goby of another roof material arranged adjacently and is linked to the second folded portion of the lower goze, and a main body portion of the fastening means In the recess of the second folded portion,
However, it is preferable as a specific means for solving the problems of the present invention.

  According to the horizontal roofing material of the present invention having the above-described configuration, since the connection in the left and right direction (wife direction) of the roofing material only needs to overlap the upper joint and the lower joint, efficient construction is possible. Become.

  In addition, according to the roofing material for the horizontal roof according to the present invention, a flat outer surface is formed between the upper joint and the adjacent roofing material by contact with the side end surface of the stepped portion. Since the abutting portion and the back grounding portion that forms the outer surface with the stepped portion between the abutting portion and the roof material arranged adjacent to each other by contact with the outer surface of the roof body are provided, they are arranged adjacent to each other. It is possible to obtain a flat connection part by bringing the abutting part into contact with the side end surface of the stepped part of the roofing material, and the back grounding part is brought into contact with the outer surface of the adjacent roofing material. By doing so, it is possible to obtain a connecting portion with a step, thereby making it possible to adopt two types of connection forms with a single roofing material, and to expand flexibility in roofing construction.

  In addition, by providing unevenness extending along the eaves and the ridge direction on the upper surface (overlapping surface) of the stepped portion formed in the lower joint, even if rainwater enters from between the upper joint, Rainwater is highly waterproof because it flows down to the eaves along the recess due to the slope of the roof. Since the unevenness of the roof material can be made substantially the same due to the unevenness, it is possible to avoid shape deformation such as warping and twisting.

  Moreover, according to the roofing material for the horizontal roof according to the present invention, the lower side of the long side portion is formed with a first folded portion that forms a recess opened toward the eaves side, and an end of the first folded portion. A second folded part that forms a recess open to the building and connected to the building, and a fixed part that connects to the end of the second folded part and connects to the roof base material to fix and hold the roof material body It is composed of a piece, and the upper goby is provided with a recessed portion opened toward the ridge side and a folded portion that fits into the recessed portion formed in the first folded portion of the lower goby. In addition, it becomes possible to easily connect roofing materials in the building direction, so that the lifting work can be simplified.

  In addition, when the roof material is molded from a single plate by providing irregularities that are almost equivalent to the irregularities of the lower joint at the edge in the width direction of the lower goby, the unfolded length becomes almost the same and warps and twists. It is possible to prevent deformation of the shape.

  Furthermore, according to the roofing material according to the present invention having the above-described configuration, the upper goby is connected to the roof material body to form a vertical wall (a wall forming a small edge) and a lower end of the vertical wall. The vertical wall is pushed inward at the edge in the width direction of the upper goby to form a recess and connect to the stepped-down portion of the lower joint. By providing the step-down portion, it is possible to connect the roofing materials flatly by a simple operation of simply fitting the upper roofing of another roofing material that is adjacently disposed.

  In particular, the vertical wall of the edge in the width direction of the upper goby is pushed inward to form a recess, so that it is possible to make the developed length almost the same as the unevenness of the lower joint. In addition, twisting does not occur and shape deformation does not occur.

  Moreover, according to this invention, a heat insulation, the heat retention effect, etc. can be improved by sticking a heat insulating material on the back surface of a roof material main body.

  Furthermore, according to the connecting structure of the roofing roof material having the above-described configuration, the snow stop fitting is connected to the second folded portion of the lower goby where the folded portion is located, and is fixed and held. In addition to enabling efficient attachment of the snow stopper, the folding portion has a triple structure in which three plates are stacked, so that the pullout strength of the bracket is increased.

  Further, according to the connecting structure of the roofing material for the horizontal roof according to the present invention, since the connection in the second folded portion of the lower goby is performed by the fastening means directly linked to the second folded portion of the lower goby, At the same time that the roof is raised, the snow stopper can be securely attached by simple work. Since the main body portion of the fastening means is housed in the concave portion of the second folded portion, the appearance shape of the roofing material is not affected.

  Further, according to the connecting structure of the roofing material for the horizontal roof according to the present invention, the connection at the second folded portion of the lower goby passes through the upper goby of another roof material arranged adjacent to the second goby. Since it is made by the fastening means linked to the second folded portion, the snow stopper can be securely attached without performing an operation of peeling off the roof material even after finishing the roofing. Also in this case, since the main body portion of the fastening means is housed in the concave portion of the second folded portion, the appearance shape of the roofing material is not affected.

  Reference numeral 1 in FIGS. 1 to 6 denotes a roof material body that can be constituted by a galvanized steel sheet, an aluminum zinc alloy-plated steel sheet, an aluminum plate, a stainless steel plate, a copper plate, and their coating or coating film products.

  This roofing material body 1 has a wide rectangular shape having a pair of left and right short sides 1a, 1b and long sides 1c, 1d that sandwich these short sides 1a, 1b vertically (eave, building direction). Consists of short materials. Here, let the long side part 1c be an eaves side long side part, and let the long side part 1d be a ridge side long side part.

  In addition, as shown in FIG. 1, 2 is an S-shape with a width w toward the short sides 1 a and 1 b over the entire area between the long sides 1 c and 1 d, as shown in FIG. This is a folded portion that is folded and formed with a step e on the outer surface of the roofing material body 1.

  Moreover, 3 is a lower goby provided in the ridge side long side part 1d. As shown in FIG. 7, the lower goby 3 connects the roof material bodies 1 to each other by being fitted to an upper gob of another side roofing material arranged immediately above (ridge side).

  In this example, the lower goby 3 is connected to the end portion of the first folded portion 3a that forms a recessed portion opened toward the eave side, and is opened toward the ridge side. A second folded portion 3b that forms a concave portion, and a fixed piece 3c that is connected to the end of the second folded portion 3b and is connected to the base material of the roof to fix and hold the roof material body 1 (See FIG. 4).

  In addition, a lower goby 3 'having a size smaller than that of the lower goby 3 is formed at the edge (short side portion side) in the width direction of the lower goze 3 (see FIGS. 5 and 6). This lower goby 3 'has a step-down allowance equivalent to the step-down portion formed in the lower joint, which will be described later, so that even if another roof material upper joint is overlapped, the lower gobe 3' Does not come into contact with the upper joint.

  Moreover, 4 is an upper goby provided in the eaves side long side part 1c (refer FIG. 4, FIG. 6). This upper goby 4 is connected to the lower goze 3 of another side roofing material that is arranged immediately below (eave side) and connects the roofing material bodies to each other (when the roofing material body is located in the eaves) Fits with the eaves drainer.)

  The upper goby 4 is composed of a vertical wall (wall forming a forehead) 4a connected to the roofing material body 1 and a horizontal wall (folded portion) 4b connected to the lower end of the vertical wall 4a and folded back toward the ridge side. . A stepped portion 4c lower than the surface of the vertical wall 4a is provided on the vertical wall 4a at the edge in the width direction of the upper goby 4 (see FIG. 3).

  The upper goby 4 is formed with a recess opened toward the ridge side by the vertical wall 4a and the horizontal wall 4b, and the horizontal wall 4b is formed in the first folded portion 3a of the lower goby 3 as shown in FIG. The roof material main body 1 is connected to the eaves and the ridge direction by fitting in the recessed part made.

  Reference numeral 5 denotes a lower joint provided on the short side 1b. The lower joint 5 is formed with the step-down portion 5a that is lower than the outer surface of the side roofing material as shown in FIG. A plurality of recesses 5b and protrusions 5c are provided. The concave 5b and the convex 5c are formed by press molding, and the protruding end surface of the convex 5c is at a position lower than the outer surface of the roofing material.

  6 is an upper joint provided in the short side part 1a. This upper joint 6 is overlapped with the lower joint 5 of another roofing material that is adjacently disposed in the wife direction (lateral direction). As shown in FIG. An abutting portion 6a that makes contact with the side end surface of the step-down portion 5a of the lower joint 5 of another roof material that is disposed adjacently and enables a flat connection portion to be formed therebetween, and another disposed adjacently A back grounding portion (flat portion) 6b is provided which forms a connection portion with a step between the adjacent roof material and the adjacent roof material by contact with the surface of the roof material.

  A folded portion 6c is formed at the distal end portion of the upper joint 6 and is bent toward the back surface side of the roofing material. In this example, the folded portion 6c serves as the back grounding portion 6b.

  Moreover, 7 is the unevenness | corrugation provided in the edge part (fixed piece 3c) of the lower goby 3 (refer FIG. 2, FIG. 6). The unevenness 7 is provided at the same time as the formation of the recesses 5b and protrusions 5c in order to have substantially the same unfolded length as the recesses 5b and protrusions 5c of the lower joint 5, so that the unfolding length of the roofing material is approximately the same. Prevents deformation such as warping and twisting.

  8 is a recessed portion (see FIG. 5) formed by pushing the vertical wall 4a inward in a stepped-down portion 4c provided at an edge in the width direction of the upper goby 4, and 9 is a horizontal wall 4b of the upper goze 4 (See FIG. 3).

  When connecting the roofing material for the horizontal roof having the above-mentioned configuration in the direction of the wife, as shown in FIGS. 9 and 10, the upper joint 6 of the roofing material is overlapped with the lower joint 5 of the roofing material arranged adjacently. Match.

  Then, as shown in FIG. 11, a connection part with a step similar to that of the folding part 2 is formed between them. Thereby, the connection part of a roof material will look the same as the folding part 2, and it will be lifted up to the roof excellent in the aesthetics which cannot confirm where this connection part exists. In addition, the overlap margin L (refer FIG. 10) in the back surface grounding part 6b of the upper joint 6 can be about 10 mm.

  On the other hand, the upper abutment 6a of the upper joint 6 is brought into contact with the side end face of the stepped portion of the lower joint 5 of the adjacent roof material as shown in FIG. When the joint 6 is overlapped with the lower joint 5 of the roofing material arranged adjacently, a flat connection portion is formed between them as shown in FIG.

  The raising of the roof having the flat connecting portion as described above is particularly effective when applied to a roofing material having a flat outer surface to which the folding portion 2 is not added. I can raise it.

  As described above, the roofing material according to the present invention can easily change the connection form of the roofing material when rolling the roofing material in the direction of the wife, and it is necessary to prepare another roofing material. And flexibility is expanded.

  Further, at the edge in the width direction of the upper goby 4, the AA cross section and the BB cross section of FIG. 1 are overlapped, as shown in FIG. 14, the lower allowance equivalent to the stepped down portion 5 a of the lower joint 5. Since the stepped-down portion 4c having the shape is formed, even when the flat connecting portion is formed, even if the vertical wall 4a of the upper goby 4 of another roofing material arranged adjacent to each other is overlapped, there is a step at this portion. Never formed.

  Furthermore, when the roofing material for a horizontal roof of the present invention enters rainwater from a connecting portion (lateral direction) of the roofing material, the rainwater is along a recess 5b provided on the upper surface (overlapping surface) of the stepped portion 5a. Immediately it flows down to the eaves side. One or more of the concaves 5b and 5c are preferably provided for rainwater from the lateral direction, so that even if rainwater enters, it will be discharged from the first concave 5b to the eaves side by the slope of the roof. It becomes.

  Considering the case where the roof has a gentle slope or inundation during heavy rain, rainwater is provided by providing a waterproof tape t as shown in FIG. It is also possible to reliably avoid the intrusion.

  The first folded portion 3a and the second folded portion 3b are brought into contact with each other at the edge in the width direction of the lower goby 3 (the portion where the lower joint 4 is formed) instead of the lower goze 3 '. A flat portion h as shown in FIG. 16 formed by the above can be provided, whereby the strength of this portion can be increased.

  Further, at the edge of the upper goby 4 in the width direction (portion where the lower joint 5 is formed), the concave portion 8 is formed on the vertical wall 4a and the concave and convex portion 9 is provided on the horizontal wall 4b (see FIG. 3). The reason is that the recesses 5b and 5c of the lower joint 5 are integrally formed by press molding, so that the development length increases by the depth, and the lower joint 5 is directed in the width direction of the roofing material. This is because the vertical wall 4a and the horizontal wall 4b need to be matched to this.

  By forming the concave portion 8 in the vertical wall 4a and providing the concave and convex portion 9 in the horizontal wall 4b, it becomes possible to adjust the developed length to be the same as the developed length of the lower joint 5, and shape deformation such as warping of the roofing material during molding processing. Can be prevented.

  In particular, since the vertical wall 4a protrudes outward as much as it is deeply processed by folding, it is important to provide the concave portion 8 at the edge in the width direction of the vertical wall 4a.

  As described above, the roofing material body 1 has been described by taking the side roofing material provided with the folding portion 2 as an example, but it goes without saying that the present invention can also be applied to a roofing material having a flat outer surface. .

  Moreover, in this invention, the level | step difference e formed by the folding part 2 is formed also in the other side, and the folding part as shown in FIG. 17 which enabled it to visually recognize a folding part from two directions of a roof A side roofing material with 2 'can also be applied.

  In addition, as shown in FIG. 18, the horizontal roofing material according to the present invention may have a heat insulating material 10 attached to the back surface of the roofing material for the purpose of enhancing the effect of heat insulation or heat insulation. .

  In order to lift the roof using the roofing material according to the present invention, the following construction procedure is specifically followed.

  First, as shown in FIG. 19, the roofing 12 is laid on the field board 11, and then a draining board 13 is attached to the eaves, and the upper goby 4 of the roof material body 1 is fitted to the draining board 13.

  Next, the fixing piece 3c of the lower goby 3 of the roofing material is placed on the roofing 12, and is fixed to the field board 11, the rafter or the main house 14 with a nail or a screw at a necessary interval. And if the roofing material main body 1 is fixed, it is fixed by selecting either a flat connecting part or a connecting part with a step for the joint parts of the roofing material. The upper joint 6 of another roof material arranged adjacent to the lower joint 5 of the roof material is overlapped.

  Thereafter, this operation is repeated to move in the direction of the wife, and if the end is reached to the end of the wife (end of the eaves), the same operation is performed on the building side.

  In order to connect the roofing material in the eaves and ridge direction, the horizontal wall 4b of the upper goby 4 of the roofing material arranged adjacent to the first folded portion 3a of the lower goby 3 of the roofing material that has been fixed is inserted. And fixing the fixing portion 3c of the lower goby 3 of the roofing material to be attached to the base plate, and repeating this operation in the eave and ridge direction.

  FIG. 20 shows a state (finished) of a side roof that forms a connecting portion with a step. According to the present invention, it is possible to form a connection portion having a step similar to that of the folding portion 2 in the connection portion of the roof material without impairing the waterproof property, and thereby, a roof having a good aesthetic appearance is lifted up. It becomes possible.

  Next, the case where a snow stopper is attached is demonstrated based on FIG. 21 about the connection structure of the roofing material for a horizontal roof comprised in the said point.

  Reference numeral 15 in FIG. 21 is a snow stop fitting installed on the outer surface of the roof material body 1. The snow stopper 15 is integrally connected to the metal body 15a standing on the roof body 1 in a direction orthogonal to the surface of the roof body 1, and the lower end of the metal body 15a. The connecting piece 15b extending along the one end, the one end connected to the connecting piece 15b, and the other end facing the vertical wall of the second folded portion 3b of the lower goby 3, the metal fitting body 15a and the connecting piece 15b Are composed of a plurality of reinforcing ribs 15d.

  The snow stop fitting 15 is attached to a portion where the folding portion 2 is provided (range of the width dimension w). In order to attach the snow stop bracket 15 simultaneously with the raising of the roof, the screw 16 is directly linked to the vertical wall of the second folded portion 3b of the lower goby 3 by fastening means (including a nail or the like) such as a screw 16. The main body part (under the neck part) is housed in the space of the recess. And after that, what is necessary is just to fit the upper goby 4 of another roofing material adjacently arranged by the ridge side.

  According to the connecting structure of the roofing material for the horizontal roof having such a configuration, the snow stopper 15 is firmly connected at the folding portion 2 where the three plates are combined, and the snow stopper 15 can be easily made by snow sliding. It will not drop out. Moreover, since the screw | thread 16 is accommodated in the internal space of the recessed part formed of the 2nd folding | turning part 3b, there exists an advantage which does not affect the external appearance shape of a roof.

  The vertical wall of the second folded portion 3b is preferably provided with a recess K so that the screw 16 does not slip when the screw 16 is driven or when the screw 16 is screwed.

FIG. 22 shows another example of the connecting structure of the roofing material according to the present invention.
This example is an example in which the snow stopper 15 is attached to a roof that has already been lifted. In this case, the snow stopper 15 is a folded portion of the upper goby 4 of another roof material main body 1 disposed adjacent to the ridge side. It connects with the 2nd folding | turning part 3b of the lower goby 3 through 4a.

  In such a connection structure, the screw 16 passes through the folded portion 4a of the upper goby 4 of the roofing material body 1 located on the ridge side, but the attachment portion of the snow stop fitting 15 is located 3 where the folded portion 2 is located. Since it has a heavy structure (four-layer structure including the roof materials arranged adjacent to each other) and the roof has a slope, rainwater does not easily enter.

  In this structure, as a precaution, a waterproof packing 17 may be provided between the head of the screw 16 and the folded portion 4a of the upper goat 4 of the roofing material body 1.

  Since the snow stopper 15 is also attached to the portion where the folding portion 2 is provided, as in the case shown in FIG. 21, the snow stopper 15 is firmly connected to the roof material body 1. The
