DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exterior material to be installed on a roof or a wall of a building, and more particularly to an oblique roofing exterior material, an oblique roofing exterior structure, and a method for constructing an oblique roofing exterior.

[0002]

2. Description of the Related Art Conventionally, the types of roofing of exterior materials and exterior structures used for medium and large buildings can be broadly classified into two types, vertical roofing and horizontal roofing, except for tiled roofing. In the state where such a roofing format was taken for granted, it was necessary to pursue changes in the design in small parts, for example, in the case of vertical roofing, the shape and size of the bar-shaped part were changed,
In the case of horizontal roofing, the design of the exterior of a building, such as a roof or a wall, is changed by changing the height or effective width of a step portion of a roof plate.

[0003]

However, in the above-mentioned conventional examples of the above-mentioned roofing styles and the exterior materials used in these roofing styles which do not change in basic shape, the answer to the market demand for a new design is always answered. Not in a situation. Also,
Conventional rainwater treatment for roofs, such as the vertical roofing, the horizontal roofing, and the tiled roofing, only flows down from the ridge to the eaves on the exterior surface. In such a situation, there is a possibility of overflow at the joint of the roofing material and a water leakage accident.

On the other hand, as a roof having a relatively new design, there has been proposed a product having a substantially smooth exterior surface as described in Japanese Utility Model Laid-Open No. 53-40626. However, the roof having a substantially smooth exterior surface has the following problems. First, there is no change in the design of the roof surface even if the viewpoint position with respect to the roof surface is changed. Second, if the roof has a slope of more than 10 degrees, the roof surface does not get caught at all. Therefore, during construction and subsequent maintenance, it is possible that the members for the unconstructed parts may slide down, or in the worst case, may lead to an accidental fall of the worker. In order to prevent personal injury and property damage caused by falling snow in the surrounding area, snow stoppers are often installed. However, it is difficult to install them on the substantially flat roof. However, the snow stopper may impair the original design of the roof. In addition, the fact that there is no catch in the sliding direction is common to the roofing material of the horizontal roofing and the vertical roofing to a certain extent, and it goes without saying that the sliding direction matches the water flow direction. It is caused by doing.

Accordingly, an object of the present invention is to provide an unprecedented new construction surface, and at the same time, to provide an exterior having both the performance required for architectural exterior materials such as improvement in rain performance and worker safety. It is to provide a material, an exterior structure and an exterior construction method.

[0006]

Means for Solving the Problems In order to achieve the above object, the exterior material of the present invention is an oblique roof exterior material which is laid obliquely with respect to the direction of water flow on a sloped roof or an outer wall. The oblique roofing exterior material has both edges formed so as to intersect at least an acute angle or an obtuse angle with respect to the flow direction of water, and has a substantially flat shape as an exterior surface as described in claim 1. An engaging portion is formed at one end of the portion, and a gutter portion is formed at the other end of the substantially flat portion. The engaging portion is on the water side, the gutter portion is on the water side, and the gutter portion is oblique. The lower part of the water is the drainage part, and the upper part of the diagonal water is the water stop part. Here, the engaging portion is a portion that engages with a gutter portion or other members of the oblique roofing exterior material adjacent to the lower side, and various shapes can be assumed in the embodiment, as described later in detail. In addition, the gutter portion receives rainfall of the oblique roofing exterior material adjacent to the upper side, and various shapes can be assumed in the embodiment.

[0007] The oblique roofing exterior material having such a configuration is as follows.
It can create arrow-shaped patterns on the construction surface of sloped roofs and outer walls, and can respond to market demands for new designs as new exterior materials used for new roofing styles. Further, since the gutter portion is formed at the other end of the substantially flat portion of the oblique roofing exterior material, the oblique roofing exterior material itself has a gutter function. And by making the engagement part of one end of the substantially flat part below the water flow direction and the gutter part above the water flow direction, the gutter part is obliquely roofed adjacent to the upper stage side. Collect rainwater, etc. flowing down the exterior surface of the exterior material.
The collected rainwater and the like are drained from a drain provided on a diagonally lower side of the gutter part inclined with respect to the flow direction of the water.
In this case, since the water stopping portion is provided on the diagonally upper side of the gutter, rainwater and the like do not flow backward. That is, in the oblique roofing exterior material according to the present invention, since the rainwater does not flow down from the ridge to the eaves direction on the exterior surface, the amount of water flowing down on the roof surface near the eaves does not increase. Even in the accompanying situation, there is no possibility of water leakage due to overflow at the joint of the roofing material.

[0008] Further, as a more specific shape of the oblique roofing exterior material, as described in claim 2, the planar shape thereof is substantially a parallelogram, and a pair of the engaging portion and the gutter portion is formed. Of the opposite side. In the oblique roofing exterior material having such a shape, the side edges corresponding to the other set of opposite sides of the parallelogram are respectively positioned parallel to the flow direction of the water on the construction surface, and the gutter portion and the engaging portion are provided. Can be arranged so as to be inclined with respect to the flow direction of water. Therefore, it is possible to accurately roof a continuous arrow feather pattern in the vertical direction of the construction surface, and also to accurately roof a continuous arrow feather pattern in the girder direction, using a new exterior material. It can respond to market demands for innovative design as a roofing format.

Further, the engaging portion of the oblique roofing exterior material is formed by bending one end of a substantially flat portion toward the back side of the oblique roofing exterior material. The portion is formed from a drooping portion having the other end of the substantially flat portion folded down, a bottom portion bent outward from the drooping portion, and a rising portion rising from the bottom portion. Is started to form a water stop section. In the oblique roofing exterior material having such a configuration, a U-shaped gutter portion having a substantially upwardly open cross section is formed integrally with the oblique roofing exterior material, and the water stop portion is integrally molded with the oblique roofing exterior material. Therefore, the roof surface and outer wall can be constructed with almost no on-site processing, and the workability is extremely high. As a result, it is possible to quickly and accurately respond to the market demand for a novel design with a new roofing style using new exterior materials. be able to.

The gutter portion originally receives rainwater and drains it to the ground. As described in claim 4, an oblique roofing exterior material (above) is provided on the bottom of the gutter portion. An engaged portion that engages with the engaging portion of the upper-stage oblique roofing exterior material) may be provided. In this configuration, the gutter portion and the engaged portion are formed integrally, so that the vertically adjacent oblique roofing exterior materials can be directly engaged with each other, and the blow-up strength and watertightness can be increased.

Further, the substantially flat portion on the side of the gutter portion may be formed as an upwardly inclined surface. Here, the substantially flat portion is inclined upward toward the gutter portion side by the upwardly inclined surface, and the relationship with the substantially flat portion on the engagement portion side of the upper-side oblique roofing exterior material. In this case, a step is formed due to the height of the slope. Further, in relation to the gutter portion, a deep gutter portion having the above-mentioned step is formed.

Therefore, in the roof surface using such an oblique roofing exterior material, the direction of travel can be changed upward by the inclined surface with respect to wind and rain that travels from below to above the exterior surface due to strong wind pressure. . That is, since the slope acts as a spoiler on the exterior surface where the wind and rain acts as a positive pressure, the direction of the action of the wind and rain pressure is changed upward, and there is an effect of scattering the wind and rain, thereby making it possible to leak water during a strong wind and rain. Can be further reduced. In addition, since the step forms a hook on the roof surface that has been roofed, it is possible to prevent a member for an unconstructed portion from slipping down during construction of a sloped roof or during subsequent maintenance. Can be prevented. Further, in the snow-covered area, since the step has a snow stopper effect, it is not necessary to separately attach a snow stopper, and as a result, there is no danger of water leakage accompanying the attachment of the snow stopper. Moreover, not only does the snow stopper not impair the original design of the roof, but the design changes due to changes in the line of sight with respect to the roof surface are large, and the exterior surface, which is a new design that has never been seen before, is further changed. It can be rich. Furthermore, since a deep gutter part with a step can be formed, a larger amount of water can be accepted and the gutter function can be improved.
From this point, it is possible to reliably prevent an increase in the amount of flowing water on the roof surface near the eaves.

[0013] Next, an oblique roofing structure according to claim 6 can be used as an exterior structure capable of constructing a novel construction surface which has not existed in the past, improving the performance of the rain and improving the safety of workers. Provide exterior structure. That is, a gutter member is laid at predetermined intervals along the direction of flow of water on a sloped roof or the lower ground of an outer wall, has a substantially flat portion at the center, an engagement portion at one end, and a gutter portion at the other end. In the oblique roofing exterior structure that is laid obliquely so that the side edge that becomes either the left or right underwater faces the gutter member, the center line is located approximately at the center between the gutter members. Divide the base surface to be attached with the exterior material into two parts, and drain the drainage part on the gutter part on the underwater side edge of the exterior material,
A water-stop portion is provided on the gutter portion on the water-side side edge, and the water-stop portion of the adjacent exterior material is laid so as to be along the center line, and each exterior material is directly fixed with a fixing tool, or the exterior material is provided. This is an exterior structure fixed to a base via a holding member. In such an exterior structure, the exterior material has a substantially flat portion at the center, an engagement portion at one end, and a gutter portion formed at the other end, and the exterior material is obliquely roofed on a base. Yes, for example, use an exterior material that has a rectangular shape with no processing at both ends and can be processed at the site. Of course, the exterior material processed beforehand,
For example, any of the above-mentioned oblique roofing exterior materials may be used.
In addition, the meaning of the engaging part and the gutter part of the exterior material is the same as that of the slanted exterior material. In addition, the foundation is a wooden structure, a steel frame structure, a concrete structure, etc., and refers to any building frame to which fixing devices such as nails, screws, anchors, etc. can be attached, and a tree to be laid on the frame by heat insulation or other as needed. Including base boards such as wool cement board. Further, the gutter member drains rainwater or the like collected in the gutter portion of the exterior material.

When such an exterior structure is constructed in the vertical direction of the construction surface, the gutter portion becomes shaded, an arrow feather pattern is formed in units of the mounting target base surface, and an arrow feather pattern using the gutter member as an arrow pattern is also formed. It will be formed on the construction surface. Therefore, when the construction surface is viewed from the front, a pattern in which the arrow blades are continuous can be confirmed even from a distance due to the shadow created by the gutter part which is the seam of the exterior material. Also, although there are differences depending on the sun altitude, when viewing the construction surface from either the left or right diagonal direction, the shadow of the seam inclined in the observation direction is emphasized and the shadow of the seam in the opposite direction fades, so the construction On the surface, the emphasized arrow wing pattern and the weakened arrow wing pattern appear as intermittent patterns, and the design is different from the pattern seen from the front. Therefore, it is possible to obtain an exterior structure in which the pattern changes according to the viewpoint, rather than the monotonous design of vertical lines or horizontal lines, using conventional roofing materials or horizontal roofing materials. Can be answered. In addition, rainfall on the individual cladding material collects in the gutter of the lower cladding material, is guided to the gutter member from the drainage portion on the lower side edge of the cladding material, and the rainwater guided to the gutter member is affected by wind. Since the water flows down the gutter space which is hard to receive, the amount of rainwater flowing down the surface of the exterior surface does not increase downward as in the case of the conventional roof, and the possibility of water leakage during strong winds and rains is extremely low.

In the above exterior structure, an auxiliary support member is interposed and fixed between the base and the exterior material, and the exterior material is directly fixed to the auxiliary support member, or the auxiliary support member is provided. The exterior material holding member may be fixed to the member. Here, the auxiliary support member is for supporting the back surface side of the exterior material, and by using such an auxiliary support member to fix the exterior material, or by fixing the exterior material holding member, the exterior material can be further improved. It can be stably and firmly supported.

In the case where the upper exterior material (upper exterior material) and the lower exterior material (lower exterior material) are connected to each other, the upper exterior material is connected as described in claim 8. A gutter space open to the front side is formed between the lower edge of the substantially flat portion of the material and the upper edge of the substantially flat portion of the exterior material located below. The gutter space has a substantially inverted V in units of a mounting target base surface.
A letter-shaped pattern is formed, and a recess is formed on the construction surface. Such a gutter space functions as a rain gutter, and as a concave portion formed on the construction surface, forms a catch on the roof surface, so during the construction of the sloped roof or during subsequent maintenance, the member for the unconstructed portion is used. Sliding can be prevented, and a fall accident of the worker can be prevented. In addition, in the snowy region, since the concave portion has a snow stopper effect, there is no need to separately attach a snow stopper, and as a result, there is no danger of water leakage due to the attachment of the snow stopper. Moreover, the original design of the roof is not impaired by the snow stopper.

As an exterior material used in the oblique roof exterior structure of the present invention, an exterior material having a substantially flat portion on the side of the gutter portion having an upwardly inclined surface as described in claim 9 may be used. . In the exterior structure using such an exterior material, a step due to the inclination height of the inclined surface is formed on the construction surface in relation to the substantially flat portion on the engagement portion side of the upper stage exterior material, and in the relationship with the gutter portion, A deep gutter part with a step is formed on the construction surface.

Therefore, on the construction surface, the direction of travel can be changed upward by the inclined surface with respect to the wind and rain that travel upward from below the exterior surface due to strong wind pressure. That is, on the exterior surface where wind and rain act as positive pressure,
Since the inclined surface works as a spoiler, it has the effect of changing the action direction of wind and rain pressure upward, and scattering wind and rain,
As a result, the possibility of water leakage during a strong wind and rain can be further reduced. In addition, since the step forms a hook on the roof surface, during construction of the sloped roof, and during subsequent maintenance, it is possible to prevent a member for an unconstructed portion from sliding down,
In addition, it is possible to prevent a fall accident of the worker. Further, in the snow-covered area, since the step has a snow stopper effect, it is not necessary to separately attach a snow stopper, and as a result, there is no danger of water leakage accompanying the attachment of the snow stopper. Moreover, not only does the snow stopper not impair the original design of the roof, but the design changes due to changes in the line of sight with respect to the roof surface are large, and the exterior surface, which is a new design that has never been seen before, is further changed. It can be rich. Furthermore, since a deep gutter part with a step can be formed, a larger amount of water can be accepted and the gutter function can be improved. It can be reliably prevented.

According to a tenth aspect of the present invention, an oblique roofing exterior structure using an exterior material having the above-described "upwardly inclined surface" has substantially the same operation and effect. Fitting means are respectively provided in the gutter portions of the exterior materials vertically adjacent to each other, and the gutter space is covered, and a convex cover material raised above a substantially flat portion is fitted to the fitting means. Is also good. Here, since the convex cover material (cover) acts in the same manner as the inclined surface, the cover acts as a spoiler on the exterior surface where the wind and rain acts as a positive pressure, and changes the action direction of the wind and rain pressure upward to reduce the wind and rain. There is an effect of scattering, which can further reduce the possibility of water leakage during heavy rain. In addition, since the cover material becomes a step and forms a hook on the roof surface that has been roofed, it is possible to prevent a member for an unconstructed portion from sliding down during construction of a sloped roof or during subsequent maintenance. Can be prevented from falling. Further, in the snow-covered area, since the cover material has a snow stopper effect, it is not necessary to separately attach a snow stopper, and as a result, there is no danger of water leakage accompanying the attachment of the snow stopper. In addition, the snow stopper does not impair the original design of the roof, and the cover material forms a substantially V-shaped floating pattern. The construction surface can be a different design from the construction surface.
Further, the cover member can block rainwater against rainfall of the individual exterior members and guide the rainwater to the gutter member. Therefore, rainwater flows down the gutter space, which is hardly affected by wind, so that the amount of rainwater flowing down the surface of the exterior surface does not increase downward as in the case of conventional roofs. The probability is extremely low.

In each of the above exterior structures,
As described in 1, the snow melting device may be provided along one or both of the bottom and the side of the gutter member. The snow melting device is capable of releasing heat energy, and is, for example, a planar heater such as an electric heater, a hot air duct, a hot water pipe, or the like. In such a configuration, the snow cover of the gutter member continuous in the eaves ridge direction will be melted, and the snow cover is gently guided to the gutter member along the gutter portion or the convex cover of the exterior material.
The snow on the entire construction surface can be smoothly melted. As a result, it prevents the snow from falling in large quantities at once,
It is possible to prevent personal injury and property damage caused by falling snow around the building.

Further, in each of the above exterior structures,
As described in 2, a back-up material that is continuous in the eaves ridge direction and has a support portion and a space portion that support the exterior material at a plurality of locations may be interposed on the back side of the exterior material. . In such a configuration, the support portion of the backup material obliquely intersects with the engaging portion and the gutter portion, which are the molded portion of the exterior material. Therefore, the surface strength is improved with respect to a positive load such as a snow load. Further, since a space communicating with the eaves ridge direction is formed by the space portion continuing in the eaves ridge direction, dew condensation inside the structure can be prevented.

Further, the back-up member may be made of a non-permeable material or a member subjected to a non-permeable treatment, and an end portion thereof may face the drainage space of the gutter member. Here, the member that has been subjected to the water-impermeable treatment can be made by subjecting a backup material made of a water-permeable material to a waterproof treatment. In such a configuration, since the backup material is made of a non-permeable material or a member that has been subjected to non-permeable treatment, even if unexpected leakage or condensation occurs, the valleys of the wavy surface of the backup material formed by the support portion and the space portion. Accordingly, the water can flow down from the ridge direction toward the eaves direction, and the drainage can be drained by the gutter member by the end of the backup material facing the drainage space of the gutter member, thereby improving the performance of rain.

Next, an exterior construction method capable of constructing a novel construction surface which has not existed in the past, improving the performance of rain-closing, and ensuring the safety of workers, is described in claim 1.
4. A method for constructing an oblique roof exterior according to item 4. That is,
A first step in which gutter members are laid at predetermined intervals along the direction of flow of water on a sloped roof or an outer wall under the ground, and the base surface to be attached with the exterior material is bisected with the center line between the gutter members as a center line. And a substantially flat portion in the center, an engagement portion at one end, a gutter portion at the other end, a drainage portion at one of the left and right underwater side edges, and a drainage portion at the waterside side edge. The second step of laying the water blocking portion, the exterior material formed respectively, the drainage portion facing the gutter member, and the water blocking portion of the adjacent exterior material obliquely so as to be along the center line, and This is an exterior construction method in which the exterior material is installed in a third step of fixing the exterior material to a base directly with a fixing tool or via an exterior material holding member. The exterior material here has a substantially flat portion at the center, and an engagement portion at one end thereof,
It is a rectangular exterior material with a gutter part formed at the other end,
One that can be processed at the both ends at the site or one that has been processed in advance, for example, any of the above-mentioned oblique roofing exterior materials is used.

According to this construction method, when a prefabricated exterior material is used, the exterior of a sloped roof or a wall can be constructed as it is, so that the workability is extremely high. As for the on-site processing, the exterior of the roof and the wall can be installed after the end processing and the water stop section processing, and the workability is good. In addition, when the construction surface is viewed from the front, a pattern in which the arrow blades are continuous can be confirmed from a distance due to the shadow created by the gutter part which is the seam of the exterior material. Also, although there are differences depending on the sun altitude, when viewing the construction surface from either the left or right diagonal direction, the shadow of the seam inclined in the observation direction is emphasized and the shadow of the seam in the opposite direction fades, so the construction On the surface, the emphasized arrow wing pattern and the weakened arrow wing pattern appear as intermittent patterns, and the design is different from the pattern seen from the front. Therefore, it is possible to obtain an exterior structure in which the pattern changes according to the viewpoint, rather than the monotonous design of vertical lines or horizontal lines, using conventional roofing materials or horizontal roofing materials. Can be answered.
In addition, rainfall on the individual exterior materials collects in the gutter portion of the lower exterior material, and the gutter portion guides the water from the drainage portion obliquely below the water to the gutter member, and the rainwater guided to the gutter member is affected by wind. Since the water flows down the gutter space which is hard to receive, the amount of rainwater flowing down the surface of the exterior surface does not increase downward as in the case of the conventional roof, and the possibility of water leakage during strong winds and rains is extremely low.

In the above-mentioned construction method, as in claim 15, in the first step, when laying a gutter member, laying an auxiliary support member between the gutter members, and fixing an exterior material, Fixing the exterior material directly to the auxiliary support member,
Alternatively, an exterior material may be fixed to the auxiliary support member via an exterior material holding member. With this method, the exterior material can be more stably and firmly supported.

It comprises a drain portion 51 for draining the rainwater and a folded portion 36 formed by folding down the vertical edge 35 of the substantially flat portion 31. On the other hand, on the other side, one end of the gutter portion 5 is raised to form a water stop portion 52, and the adjacent portion 37 is adjacent to the oblique roofing exterior material 3 adjacent in the girder direction.

The oblique roofing exterior material 3 configured as described above
By setting the engaging portion 4 to the lower side of the water and the gutter portion 5 to the upper side of the water, the folded portion 36 and the adjacent portion 37 are moved in the water flow direction X.
When arranged substantially in parallel with the water flow direction X, it is laid obliquely with respect to the flow direction X of the water, the drainage part 51 is positioned diagonally below the water, and the water stop part 52 is positioned diagonally above the water. ing.

The drain part 51 on the obliquely lower side of the gutter part 5 is
It drains rainwater received by the gutter 5 and has a U-shaped lower opening 51a corresponding to the cross-sectional shape of the gutter 5 and an opening hanging piece 51b hanging from the bottom of the opening 51a. It is constituted by.

The water stopping part 52 on the diagonally upper side of the gutter part 5 is

Next, referring to FIGS. 5A to 5C, the second
The configuration of the water stopping portion 52A of the oblique roofing exterior material 3A according to the embodiment will be described. FIG. 5 (a) shows a metal water-stop plate 52a formed by press working. This metal water-stop plate 52a in the form of a face-door has a structure in which the oblique roofing exterior material 3A is made of metal.
The water stopping portion 52A is formed by molding the same material as the material and welding or bonding the same to integrate with the gutter portion 5 of the oblique roofing exterior material 3A (FIG. 5C). FIG. 5 (b)
Is a resin water-stop board, formed of the same material as the resin-made exterior material, and integrated with the gutter portion 5 of the oblique roofing exterior material 3A by fusion or adhesion. 52A is constructed (FIG. 5C). As described above, the water blocking portion 52A of the oblique roofing exterior material 3A according to the second embodiment is processed separately from the processing of the oblique roofing exterior material itself, whereby the manufacturing cost can be reduced. In the case where a rectangular exterior material having an engagement portion at one end of a substantially flat portion and a gutter portion formed at the other end, and both ends of which are unprocessed, is processed at the site, the water stopping portion is provided with the water stopping portion. By processing like the water part 52A, the efficiency of the field processing can be increased.

The material of the oblique roofing exterior material constituted as described above is made of surface decorative steel sheet, laminated steel sheet, plated steel sheet,
Stainless steel plate, aluminum alloy plate, titanium alloy plate, copper plate,
It is a known metal material such as a brass plate or a lead plate. Further, it may be formed from a carbon fiber laminate, a hard resin plate, or the like. When the material is a metal plate, the slanted exterior material is formed by roll forming or press forming, or a combination of both, and when the material is nonmetal, it is formed mainly by molding. The thickness of these materials is not particularly limited, but is generally about 0.4 to 1.6 mm.

The slanted exterior materials 3 and 3A of the above embodiments.
Can create an arrow-blade pattern on the construction surface of the sloped roof 1 and the outer wall 2, and can respond to the market demand for a new design property as a new roofing form with a new exterior material (FIG. 7). reference). In addition, slanted exterior material 3,3A
The gutter portion 5 itself has a gutter function. The gutter portion 5 collects rainwater and the like flowing down the exterior surface of the upper-side obliquely roofing exterior material, and drains the water from the drainage portion 51 of the gutter portion 5. Since the water does not flow down from the ridge to the eaves on the exterior surface, the amount of water flowing down on the roof near the eaves does not increase. There is no accident.

The concrete shape of each of the slanted exterior materials 3 and 3A is substantially parallelogram, so that the adjacent portion 37 and the folded portion 36 are respectively oriented with respect to the water flow direction X. The gutter portion 5 and the engagement portion 4 can be arranged so as to be parallel to each other and inclined with respect to the water flow direction X. Therefore, it is possible to accurately roof a continuous arrow feather pattern in the vertical direction of the construction surface, and also to accurately roof a continuous arrow feather pattern in the girder direction, using a new exterior material. It can respond to market demands for innovative design as a roofing format.

Further, in the slanted roof covering material 3, a pair of opposite sides including the engaging portion 4 and the gutter portion 5 are formed obliquely in advance, and the gutter portion 5 and the water stopping portion 52 are integrally formed. Therefore, the roof surface and outer wall can be constructed with almost no on-site processing, and the workability is extremely high.
Can answer accurately.

The configurations of the engaging portion 4 and the gutter portion 5 are not limited to the embodiments shown in FIGS. 1 to 3, but may be any as long as they can exert their respective functions. For example, the modes shown in FIGS. 12A to 12F and the modes shown in FIGS. Among these embodiments, FIG. 12 (c) and FIG.
As shown in (c), the gutter portion 5 is provided with the engaged portion 6 that directly engages with the engaging portion 4. That is, FIG. 12 (c) shows that the engaged portion 6 is raised from the bottom portion 54 of the gutter portion 5 and its tip is extended downward to the substantially flat portion 31 side.
Are formed in a substantially inverted J-shape. In FIG. 13 (c), the engaged portion 6 is formed by slightly rising from the bottom portion 54 of the gutter portion 5 and extending its tip parallel to the substantially flat portion 31 side. In these configurations, since the gutter portion 5 and the engaged portion 6 are integrally formed, the adjacent upper and lower oblique roofing exterior materials can be directly engaged with each other, and the blow-up strength and the watertightness are increased. be able to.

Next, referring to FIG. 6, a description will be given of an oblique roofing exterior material 3B having a different structure from the above-described oblique roofing exterior materials 3 and 3A. The oblique roofing exterior material 3B is formed by forming an upwardly inclined surface on the gutter side of a substantially flat portion of the oblique roofing exterior material.

Since the gutter portion 5 is a water-moistened portion, in this structure, when fixing with a fixing tool, a fixing tool with a waterproof washer or a waterproof cap is used, or a watertight treatment with a sealing material is required.

The holding members include the holding members 11, 1
One member such as 1A to 11F may be used, or a plurality of members may be used. For example, it is needless to say that the lower holding member and the upper holding member are configured separately.
Each of the lower holding member and the upper holding member may be configured as a plurality of members. Further, even when a holding member is used for attaching the gutter member 9, the configuration is the same as that of the exterior material holding member. The holding member may be a piece material as shown by a dotted line in FIG. 10 or may be a long material. However, when the holding member of the gutter member 9 also functions as a start material, it is preferable to use a long material.

Each of the exterior material holding members 11, 11A to 1A
1F is made of an extruded product made of aluminum or a hard resin, a pressed product such as a plated steel plate, a stainless steel plate, or the like, and a ceramic. The material thickness is not particularly limited,
In the case of an extruded product, it is approximately 1.2 to 2.5 mm.

On the other hand, without using a holding member,
FIG. 13 shows an embodiment of the oblique roof exterior structure fixed to the base.
There are those shown in (a) to (c). In FIG. 13A, the engaging portion 4 of the exterior material 3J is formed by folding one end of the substantially flat portion 31 to the back side without providing the hanging portion 53, while the gutter portion 5 is formed at the rising portion. 55 is the engaged portion 6,
A supporting portion 3a for supporting the back surface of the exterior material 3J and a fixing portion 3b for securing the exterior material 3J to the base 8 are provided. That is, the exterior material itself has the engaged portion 6 and the fixing portion 3b, and the fixing portion 3b of the lower exterior material 30A is fixed to the base 8 with a fixing tool, and the engagement portion of the upper exterior material 30B is fixed. 4 shows an exterior structure in which roofing is performed by engaging with the engaged portion 6 of the lower exterior material 30A. In FIG. 13B, the bottom 54 of the gutter 5 of the exterior material 3 </ b> K is raised to provide the substantially J-shaped engaged part 6, and the gutter 5 is used as the rising part 55. The fixing portion 3b is formed. This is common to the structure shown in FIG. 13A, in which the exterior material itself has the engaged portion 6 and the fixing portion 3b, and the fixing portion 3b of the lower exterior material 30A is This shows an exterior structure in which an engaging portion 4 of an upper exterior material 30B is engaged with an engaged portion 6 of a lower exterior material 30A and is roofed. FIG. 13C shows a case where the exterior material 3L is used.

When the exterior material 3C of the oblique roofing exterior structure constructed as described above is installed in the eaves ridge direction, the gutter portion 5 becomes shaded, and an arrow feather pattern is formed in the unit of the base surface 10 to be attached. Further, an arrow feather pattern having the gutter member 9 as an arrow pattern is also formed on the construction surface. Therefore, when the construction surface is viewed from the front as shown in FIG. 7, a pattern in which the arrow blades are continuous can be confirmed from a distance due to the shadow created by the gutter portion 5 which is a seam of the exterior material. Also, although there is a difference depending on the sun altitude, as shown in FIG. 8, when the construction surface is viewed from one of the left and right diagonal directions, the shade of the gutter portion 5 inclined in the observation direction is emphasized, and the opposite direction is observed. Since the shade of the seam of the gutter part 5 becomes faint, the embossed arrow feather pattern and the weakened arrow feather pattern appear on the construction surface as an intermittent pattern, which is a design different from the pattern seen from the front. . Therefore, it is possible to respond to the market demand for new design properties as a new type of roofing, rather than the monotonous design of vertical or horizontal lines using the conventional vertical roofing material or horizontal roofing material. Also, the rainfall on each of the exterior materials 3C is collected on the gutter portion 5 of the lower exterior material 30A, guided by the gutter portion 5 from the obliquely drainage portion 51 under the water to the gutter member 9, and then to the gutter member 9. Since the rainwater flows down the gutter space 13 which is hardly affected by the wind, the amount of rainwater flowing down the surface of the exterior surface does not increase downward as in the case of the conventional roof. Is extremely low.

Next, an embodiment according to another configuration of the oblique roofing exterior structure using the exterior material 3C will be described with reference to FIG. The main difference between the embodiment shown in FIG. 14 and the above embodiment is that an auxiliary support member 12 is arranged between the base 8 and the exterior material 3C, and the auxiliary support member 12
Is fixed to the base 8, and the exterior material 3C or the exterior material holding member 11 is fixed to the auxiliary support member 12. The auxiliary support member 12 supports the back surface side of the exterior material 3C, and has a substantially hat-shaped cross section. The two flange portions 12a, 12a serve as fixing portions for the base 8, and the top portion 12b has a top portion 12b. It is a mounting portion for the exterior material 3C and the exterior material holding member 11, and between the gutter members 9, 9
It is arranged in parallel with the gutter member. The auxiliary support member 12 is basically formed of the same material as the exterior material 3C, and is made of, for example, an extruded aluminum material.
By fixing the exterior material 3C using the auxiliary support member 12 or fixing the exterior material holding member 11, the exterior material 3C can be more stably and firmly supported.

In the embodiment shown in FIG. 14, the gutter member 9 differs from the gutter member 9 shown in FIG.
The fixing flange portion 90 for the base 8 is provided so as to extend from both sides of the bottom portion 94. A first backup member 17 is laid between the gutter member 9 and the auxiliary support member 12 and between the auxiliary support members 12 to achieve heat insulation, sound insulation, and the like. In this case, the exterior material 3 </ b> C and the exterior material holding member 11 that are not fixed to the auxiliary support member 12 and the like are fixed to a purlin, rafters, and the like that constitute the building frame via a fixing tool that penetrates the first backup material 17.

Next, a description will be given of a second embodiment of an oblique roofing exterior structure in which an auxiliary support member 12 is interposed and fixed between the base 8 and the exterior material 3C with reference to FIG. The main points of the second embodiment different from the above-described first embodiment are, firstly, the configuration of the gutter member 9A and secondly, below the adjacent portions 37, 37 of the exterior materials 3C, 3C. The point is that an auxiliary gutter member 9B is provided. The gutter member 9A is formed to have a substantially C-shaped cross section, is disposed between the auxiliary support members 12 having a substantially hat-shaped cross section, and is pressed and held by the start member 24 of the exterior material 3C. The folded portion 36 of the exterior material 3C grips the edge of the gutter member 9A and the edge of the start member 24 with respect to the gutter member 9A having such a configuration. On the other hand, below the water-side cover portion 20, an auxiliary gutter member 9B having a substantially inverted hat-shaped cross section is fitted between the auxiliary support members 12 arranged below the diagonal water surface of the exterior material 3C, Construct a three-stage rain finish of the face door 21, the adhesive tape 19, and the auxiliary gutter member 9B,
Improves the reliability of the rain. In this embodiment, the gutter member 9A and the auxiliary gutter member 9B are formed by forming a metal coil or a flat plate by roll or bender processing.

In each of the oblique roofing exterior structures configured as described above, for example, as shown in FIG. 9, the lower edge 34a of the substantially flat portion 31 of the upper exterior material 30B and the substantially flat portion of the lower exterior material 30A are provided. A gutter space 130 that opens to the front side is formed between the upper edges 32a of the 31. This gutter space 130
A substantially inverted V-shaped pattern is formed on the construction surface on the basis of the mounting target base surface 10, and a concave portion facing the gutter member 9 is formed. Since such a gutter space 130 forms a recess on the construction surface and forms a hook on the roof surface,
During construction of the sloped roof 1 or during subsequent maintenance, it is possible to prevent a member for an unconstructed portion from slipping off, and to prevent a worker from falling down. In addition, in the snowy region, since the concave portion has a snow stopper effect, there is no need to separately attach a snow stopper, and as a result, there is no danger of water leakage due to the attachment of the snow stopper. Moreover, the original design of the roof is not impaired by the snow stopper. Furthermore, since the snow load can be equally applied to the entire roof surface, instead of the local load as in snow stoppers in the conventional configuration, the local load on the foundation structure can be reduced. .

It is to be noted that an upwardly inclined surface may be formed on the gutter side of the substantially flat portion 31 of the exterior material 3C used in each of the oblique roofing exterior structures. This inclined surface is shown in FIGS. 12 (a), (b), (c) and FIG. 13 (a) as having a substantially right-angled triangular cross section, similarly to the inclined surface 7 of the oblique roofing exterior material 3B. Inclined planes 7A to 7D, FIG.
The convex inclined surface 7E shown in (d), the inclined surface 7F having a substantially trapezoidal cross section shown in FIG. 13B, and the hanging portion 53 of the gutter portion 5 shown in FIG. Inclined surface 7 according to inclination
G, there is an inclined surface 7H shown in FIG. These inclined surfaces also exhibit the same operational effects as the inclined surfaces 7 of the oblique roofing exterior material 3B, and the exterior materials to be used are selected in consideration of the construction environment such as the slope of the outer wall or the sloped roof.

Next, based on FIGS. 16A and 16B,
An embodiment of an exterior structure in which a convex cover material that protrudes above the substantially flat portion 31 and that covers the gutter space 130 shown in FIG. 9 and the like will be described. As shown in FIG.
In the embodiment of the convex cover material (hereinafter also referred to as a cover material), the cross-sectional shape is the gabber 15 having a substantially triangular cross-section, and the mounting pieces 15b and 15b are respectively provided from the cover bottom 15a to the width of the gutter space 130. Each of the mounting pieces 1
5b and 15b are provided with fitting projections 15c and 15c, respectively. On the other hand, the engaging portion 4 and the gutter portion 5 of the exterior material 3M are provided.
Are provided with fitting projections 14a, 14b as fitting means for fitting into the fitting projections 15c, 15c. Then, the rising portion 55 of the lower side exterior material 30A is held by the holding member 11.
The holding portion 11b of G holds the fixing piece 11a to the base 8 and the auxiliary support member 12, while engaging the engaging portion 4 of the upper side exterior material 30B with the engaged piece 11c of the holding member 11G. After that, the fitting projections 15c, 15c of the convex cover member 15 are fitted to the fitting projections 14a, 14b of each exterior material 3M.

The cover material 15A shown in FIG.
Replaces the fitting projections 15c, 15c of the cover member 15 with elastic projections 15d, 15d. Protrusions 15e, 15e are provided.

On the roof surface provided with the cover members 15 and 15A, the wind and rain that has proceeded upward from below along the substantially flat portion 31 of the exterior members 3M and 3N due to strong wind pressure is applied along the substantially triangular hypotenuse. The direction of travel is changed upward, and the hypotenuse functions as a spoiler.
Thus, the wind and rain reaching the apex of the triangle is scattered at the apex, so that the possibility of water leakage during a strong rain can be further reduced. At the upper part of the gutter space 130, a step D is formed on the construction surface at a substantially triangular height. Therefore, it contributes to prevention of accidents and the like during maintenance during and after construction, and in the snowy region, the step D has a snow stopper effect, so that it is not necessary to separately attach a snow stopper, and as a result, there is no snow stopper. There is no danger of water leakage due to the mounting of the bracket. Furthermore, since the snow load can be equally applied to the entire roof surface, instead of the local load as in snow stoppers in the conventional configuration, the local load on the foundation structure can be reduced. . In addition, not only does the snow stopper prevent the original design property of the roof from being impaired, but also the construction surface can have a design different from the arrow feather pattern due to the shadow created by the gutter portion 5 described above. In addition, the cover members 15 and 15A can block rainwater and guide the rainwater to the gutter member 9 against rainfall of the individual exterior materials, and the rainwater flows down the gutter space 13 which is hardly affected by wind. As described above, the amount of rainwater flowing down the surface of the exterior surface does not come down and increases, so that the possibility of water leakage during strong wind and rain is extremely low.

The shape of the cover material 15 is different from that shown in FIG.

Next, referring to FIGS. 7 to 10,
A description will be given of an embodiment of a method for constructing a slanted-roof exterior that can provide a novel construction surface that has never been seen before. An exterior material is prepared before construction. An engaging portion 4 is formed at one end of the substantially flat portion 31, while a gutter portion 5 is formed at the other end of the substantially flat portion 31, and both ends are unprocessed rectangular. The drainage part 51 and the water stop part 52 may be processed at the site using the exterior material 3C having a shape, or the exterior material processed in advance, for example, the oblique roofing exterior material 3,
Either 3A or 3B may be used.

First, as a first step, gutter members 9 are laid at predetermined intervals W along the flow direction X of water on the base 8 of the sloped roof 1 or the outer wall 2, The base surface 10 to which the exterior material 3C is attached is divided into two parts with the center as the center line C, and divided into a left base surface 10a and a right base surface 10b.
The interval W between the gutter members 9 is a distance that each drainage part 51 can face the gutter space 13 of the gutter member 9 when the adjacent portions of the exterior material 3C are respectively butted to form an inverted V-shape. .

According to such a construction method, it is not a monotonous design of a vertical line or a horizontal line made of a conventional vertical roofing material or a horizontal roofing material but a market demand for a new design property as a new roofing type. be able to. Also, the rainfall on each of the exterior materials 3C is collected on the gutter portion 5 of the lower exterior material 30A, guided by the gutter portion 5 from the obliquely drainage portion 51 under the water to the gutter member 9, and then to the gutter member 9. Since the rainwater flows down the gutter space 13 which is hardly affected by the wind,
Unlike the conventional roof, the amount of rainwater flowing down the surface of the exterior surface does not increase downward, and the possibility of water leakage during strong winds and rains is extremely low. If the exterior material to be used is the oblique roofing exterior material 3, 3A or 3B, the side edges are formed in an oblique shape in advance, and the drain portion 51 and the water stop portion 52 are formed.

In the oblique roofing exterior structure and the method for constructing the oblique roofing exterior according to the present invention, the configuration of the exterior end is not related to the problem to be solved by the present invention. An example of the receiving configuration is as shown in FIG. That is, the exterior material 3 </ b> C used for storing the exterior end is cut on site in accordance with the shape of the eaves end of the building or the like.

[0085]

According to the first aspect of the present invention, the oblique roofing exterior material is capable of forming an arrow-headed pattern on the construction surface of a sloped roof or an outer wall, and is a new exterior material used for a new roofing style. Can respond to market demands for design. Further, since the gutter portion is formed at the other end of the substantially flat portion of the oblique roofing exterior material, the oblique roofing exterior material itself has a gutter function. And by making the engagement part of one end of the substantially flat part below the water flow direction and the gutter part above the water flow direction, the gutter part is obliquely roofed adjacent to the upper stage side. Collect rainwater, etc. flowing down the exterior surface of the exterior material. The collected rainwater and the like are drained from a drain provided on a diagonally lower side of the gutter part inclined with respect to the flow direction of the water. In this case, since the water stopping portion is provided on the diagonally upper side of the gutter, rainwater and the like do not flow backward. That is, in the oblique roofing exterior material according to the present invention, since the rainwater does not flow down from the ridge to the eaves direction on the exterior surface, the amount of water flowing down on the roof surface near the eaves does not increase. Even in the accompanying situation, there is no possibility of water leakage due to overflow at the joint of the roofing material.

[0086] In the oblique roofing exterior material according to the second aspect, the side edges corresponding to the other set of opposite sides of the parallelogram are respectively positioned in parallel with the flow direction of the water on the construction surface,
Further, the gutter portion and the engagement portion can be arranged so as to be inclined with respect to the flow direction of water. Therefore, it is possible to accurately roof a continuous arrow feather pattern in the vertical direction of the construction surface, and also to accurately roof a continuous arrow feather pattern in the girder direction, using a new exterior material. It can respond to market demands for innovative design as a roofing format.

According to the third aspect of the present invention, the gutter portion having a substantially U-shaped cross section is formed integrally with the oblique roofing exterior material, and the water stopping portion is integrally formed with the oblique roofing exterior material. Molded. Therefore, the roof surface and outer wall can be constructed with almost no on-site processing, and the workability is extremely high. As a result, it is possible to quickly and accurately respond to the market demand for a novel design with a new roofing style using new exterior materials. be able to.

In the oblique roofing member according to the fourth aspect, the gutter portion and the engaged portion are integrally formed, so that the upper and lower adjacent oblique roofing members can be directly engaged with each other, and Strength and watertightness can be increased.

In the roof surface using the oblique roofing exterior material according to the fifth aspect, the direction of travel is changed upward by the inclined surface with respect to wind and rain that proceeds from below to above the exterior surface due to strong wind pressure. be able to. That is, since the slope acts as a spoiler on the exterior surface where the wind and rain acts as a positive pressure, the direction of the action of the wind and rain pressure is changed upward, and there is an effect of scattering the wind and rain, thereby making it possible to leak water during a strong wind and rain. Can be further reduced. In addition, since the step forms a hook on the roof surface that has been roofed, it is possible to prevent a member for an unconstructed portion from slipping down during construction of a sloped roof or during subsequent maintenance. Can be prevented. Further, in the snow-covered area, since the step has a snow stopper effect, it is not necessary to separately attach a snow stopper, and as a result, there is no danger of water leakage accompanying the attachment of the snow stopper. Moreover, not only does the snow stopper not impair the original design of the roof, but the design changes due to changes in the line of sight with respect to the roof surface are large, and the exterior surface, which is a new design that has never been seen before, is further changed. It can be rich. Furthermore, since a deep gutter part with a step can be formed, a larger amount of water can be accepted and the gutter function can be improved. It can be reliably prevented.

In the oblique roofing exterior structure according to the sixth aspect,
When such an exterior structure is constructed in the vertical direction of the construction surface, the gutter portion is shaded, an arrow feather pattern is formed in units of the mounting target base surface, and an arrow feather pattern having the gutter member as an arrow pattern is also formed on the construction surface. Will be done. Therefore, when the construction surface is viewed from the front, a pattern in which the arrow blades are continuous can be confirmed even from a distance due to the shadow created by the gutter part which is the seam of the exterior material. Also, although there are differences depending on the sun altitude, when viewing the construction surface from either the left or right diagonal direction, the shadow of the seam inclined in the observation direction is emphasized and the shadow of the seam in the opposite direction fades, so the construction On the surface, the emphasized arrow wing pattern and the weakened arrow wing pattern appear as intermittent patterns, and the design is different from the pattern seen from the front. Therefore, it is possible to obtain an exterior structure in which the pattern changes according to the viewpoint, rather than the monotonous design of vertical lines or horizontal lines, using conventional roofing materials or horizontal roofing materials. Can be answered. In addition, rainfall on the individual cladding material collects in the gutter of the lower cladding material, is guided to the gutter member from the drainage portion on the lower side edge of the cladding material, and the rainwater guided to the gutter member is affected by wind. Since the water flows down the gutter space which is hard to receive, the amount of rainwater flowing down the surface of the exterior surface does not increase downward as in the case of the conventional roof, and the possibility of water leakage during strong winds and rains is extremely low.

The auxiliary support member according to claim 7 supports the back side of the exterior material, and fixes the exterior material or the exterior material holding member by using such an auxiliary support member. Thereby, the exterior material can be more stably and firmly supported.

[0092] In the oblique roofing exterior structure according to claim 8,
The gutter space functions as a rain gutter, and as a recess formed on the construction surface, it forms a hook on the roof surface. Can be prevented and also
The fall accident of the worker can be prevented. In addition, in the snowy region, since the concave portion has a snow stopper effect, there is no need to separately attach a snow stopper, and as a result, there is no danger of water leakage due to the attachment of the snow stopper. Moreover, the original design of the roof is not impaired by the snow stopper.

In the exterior structure using the exterior material according to the ninth aspect, a step due to the height of the inclined surface is formed on the construction surface in relation to the substantially flat portion on the engaging portion side of the upper exterior material, In relation to the gutter part, a deep gutter part with the above-mentioned step is formed on the construction surface. Therefore, on such a construction surface, the traveling direction can be changed upward by the inclined surface with respect to the wind and rain that travels upward from below the exterior surface due to strong wind pressure. That is, since the slope acts as a spoiler on the exterior surface where the wind and rain acts as a positive pressure, the direction of the action of the wind and rain pressure is changed upward, and there is an effect of scattering the wind and rain, thereby making it possible to leak water during a strong wind and rain. Can be further reduced. Further, since the step forms a hook on the roof surface, during construction of the sloped roof or during subsequent maintenance, it is possible to prevent a member for an unconstructed portion from sliding down, and also prevent an accidental fall of an operator. be able to. Further, in the snow-covered area, since the step has a snow stopper effect, it is not necessary to separately attach a snow stopper, and as a result, there is no danger of water leakage accompanying the attachment of the snow stopper. Moreover, not only does the snow stopper not impair the original design of the roof, but the design changes due to changes in the line of sight with respect to the roof surface are large, and the exterior surface, which is a new design that has never been seen before, is further changed. It can be rich. Furthermore, since a deep gutter part with a step can be formed, a larger amount of water can be accepted and the gutter function can be improved. It can be reliably prevented.

Since the convex cover material (cover) according to claim 10 acts in the same manner as the inclined surface, the cover acts as a spoiler on the exterior surface where wind and rain acts as a positive pressure, and the direction of action of the wind and rain pressure is directed upward. And the effect of scattering wind and rain can be achieved, thereby further reducing the possibility of water leakage during strong wind and rain. In addition, since the cover material becomes a step and forms a hook on the roof surface that has been roofed, it is possible to prevent a member for an unconstructed portion from sliding down during construction of a sloped roof or during subsequent maintenance. Can be prevented from falling. Also,
In the snow-covered area, since the cover material has a snow stopper effect, it is not necessary to separately attach a snow stopper, and as a result, there is no danger of water leakage accompanying the attachment of the snow stopper. Moreover, not only does the snow stopper not impair the original design of the roof, but also the cover material forms a substantially V-shaped floating pattern. The construction surface can be a different design from the construction surface. Further, the cover member can block rainwater against rainfall of the individual exterior members and guide the rainwater to the gutter member. Therefore, rainwater flows down the gutter space, which is hardly affected by wind, so that the amount of rainwater flowing down the surface of the exterior surface does not increase downward as in the case of conventional roofs. The probability is extremely low.

In the oblique roofing exterior structure according to the eleventh aspect, the snowfall of the gutter member continuous in the direction of the eaves ridge is melted, and the snowfall is formed along the gutter portion or the convex cover of the exterior material. Since the guide is gently guided to the gutter member, the snow on the entire construction surface can be smoothly melted. As a result, it is possible to prevent a large amount of snow from falling at one time, and to prevent a personal injury or property damage accident due to snow falling around the building.

In the oblique roofing exterior structure according to the twelfth aspect, the support portion of the backup material obliquely intersects the engaging portion and the gutter portion, which are the molding portion of the exterior material.
Therefore, the surface strength is improved with respect to a positive load such as a snow load. Further, since a space communicating with the eaves ridge direction is formed by the space portion continuing in the eaves ridge direction, dew condensation inside the structure can be prevented.

In the oblique roofing exterior structure according to the thirteenth aspect, since the backup material is made of a non-permeable material or a member subjected to a non-permeable treatment, even if unexpected leakage or dew condensation occurs, the backing material is formed by the support portion and the space portion. Water can flow down from the ridge direction to the eaves direction due to the valley of the wavy surface of the formed backup material, and drainage by the gutter member can be performed by the end of the backup material facing the drainage space of the gutter member. And the performance of the rain is improved.

[0098] In the method for constructing an oblique-roofed exterior according to claim 14, when the construction surface is viewed from the front, a pattern in which the arrow blades are continuous from a distance is formed due to a shadow created by a gutter portion serving as a seam of the exterior material. But you can check. Also, although there are differences depending on the sun altitude, when viewing the construction surface from either the left or right diagonal direction, the shadow of the seam inclined in the observation direction is emphasized and the shadow of the seam in the opposite direction fades, so the construction On the surface, the emphasized arrow wing pattern and the weakened arrow wing pattern appear as intermittent patterns, and the design is different from the pattern seen from the front. Therefore, it is possible to obtain an exterior structure in which the pattern changes according to the viewpoint, rather than the monotonous design of vertical lines or horizontal lines, using conventional roofing materials or horizontal roofing materials. Can be answered. In addition, rainfall on the individual exterior materials collects in the gutter portion of the lower exterior material, and the gutter portion guides the water from the drainage portion obliquely below the water to the gutter member, and the rainwater guided to the gutter member is affected by wind. Since the water flows down the gutter space which is hard to receive, the amount of rainwater flowing down the surface of the exterior surface does not increase downward as in the case of the conventional roof, and the possibility of water leakage during strong winds and rains is extremely low. In addition, if the exterior material to be used is the oblique roofing exterior material, the side edges are preliminarily formed into an oblique shape, and since the water stop portion and the drainage portion are formed, the slope roof or wall is hardly processed on site. Since the exterior can be constructed, the workability is extremely high. On the other hand, even in the case of on-site processing, since the gutter portion and the engaging portion are formed, the on-site processing can be performed on the exterior of the roof or the wall after the end processing of the both ends and the processing of the water stop portion, and the workability is good.

According to the construction method of the fifteenth aspect, the exterior material can be more stably and firmly supported.
