[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a curved plate-shaped building material and a curved wall structure provided in a curved corner portion or the like of an outer wall of a building, for example.

[0002]

[Prior art]

 In recent years, buildings, such as factories and office buildings, have been often adopted to have a rounded corner structure, for example, in order to improve the aesthetic appearance and luxury.

When the outer wall of the building as described above is covered with a wall plate made of a colored steel plate or the like, the wall plate is formed by curving the shape along the rounded corner portion. It is necessary. An example of such a wall plate is disclosed in, for example, Japanese Patent Application Laid-Open No. 4-118455. As shown in FIG. 11, the wall plate 80 is fixedly attached to the rising part 82 ... by a bending process around the outer wall surface 81 as a wall plate part that curves along the corner of the building. It is formed by connecting the wall abutting portions 83 ... As a surface.

A plurality of slits 84 ... Are formed at a predetermined interval between the upper and lower wall rests 83 and the upper and lower rises 82 forming a horizontal plane, whereby the riser 82 and the wall rest 83 are separated from each other. Even when the outer wall surface 81 is formed by bending the vertically extended portion, it is possible to form these portions without distortion. Therefore, when the wall plate as described above is formed by individually manufacturing the outer wall surface 81 and the upper and lower rising portions 82 / wall contact portions 83 and then welding them together, correction for thermal deformation during welding is performed. Although additional work such as working, finishing of the welded surface, and subsequent color coloring is required, in the above case, it can be formed by bending, resulting in excellent shape accuracy and easy manufacture.

As shown in FIG. 12, the above-mentioned wall plate 80 has the above-mentioned wall abutting portions 83 overlapped with each other vertically and horizontally, and this portion is fixed to a corner portion of a building with screws 85 or the like. The caulking material 86 is filled in the groove-shaped gap between the adjacent rising portions 82, 82 for finishing.

[0006]

[Problems to be solved by the device]

 However, in the above-described conventional wall plate 80, a large number of slits 84 extending to the vicinity of the outer wall surface 81 are formed in the wall contact portion 83 as a fixed mounting surface and the rising portion 82 connecting the wall contact portion 83 to the outer wall surface 81. Therefore, the supporting strength of the wall contact portion 83 and the rising portion 82 with respect to the outer wall surface 81 is reduced, and therefore, for example, it becomes necessary to form the whole with a thick plate, or the outer wall surface 81 Only a short vertical length can be manufactured. As a result, a large number of wall plates 80 are required to cover the wall surface, resulting in an increase in overall cost. are doing.

On the other hand, as the building material provided in the curved corner portion of the building, in addition to the above-described wall plate 80 that covers the vertical surface, for example, a head tree provided at the uppermost end of the building or a lower end portion of the building is provided. There are drainers, and these trees and drainers have a shape in which a vertical surface and a horizontal surface are connected. Therefore, even in these headstocks and drainers, the vertical surface must be curved along the corner surface as described above, so it is difficult to form a horizontal surface connected to this vertical surface by bending as in the above. is there. For this reason, conventionally, it was necessary to manufacture the vertical surface and the horizontal surface separately from each other, and to weld these to each other to finish, resulting in an increase in cost and an excellent shape accuracy. The problem is that it is difficult.

The present invention has been made in view of the above-mentioned conventional problems, and an object thereof is to provide a plate-like building material for curved surfaces which is excellent in shape accuracy and can be manufactured at a lower cost. In addition, it is to provide a curved wall structure that can be manufactured at a lower cost as a whole and is aesthetically pleasing.

[0009]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the curved plate-shaped building material according to claim 1 of the present invention is curved at the upper and lower ends of the wall plate portion having a curved horizontal cross-section, similarly to the horizontal plane and the wall plate portion, respectively. A plurality of slits are formed on the horizontal surface and the fixed mounting surface, which are formed by connecting the fixed mounting surface in sequence and enable the formation of the horizontal plane and the fixed mounting surface by bending the extension from the wall plate. It is a plate-shaped building material for curved surfaces such as wall plates, characterized in that a reinforcing member is provided along the curved shape of the wall plate part at least on the inner surface near the upper and lower ends of the wall plate part. I am trying.

A plate-like building material for curved surfaces according to claim 2 is provided with a vertical surface portion having a curved horizontal cross-section, and a flat horizontal surface portion extending substantially horizontally is connected to at least one of upper and lower ends of the vertical surface portion. It is a plate-shaped building material for curved surfaces such as headstocks and drainers that is formed on one of the ends of the vertical surface and the horizontal surface that are continuous with each other, and has a gap approximately the same as the thickness of the other end. A fitting insertion part bent into a substantially U-shape is formed so as to have a stopper, and when the other end is inserted into the fitting insertion part, the other end is prevented from coming off. It is characterized in that a locking portion is provided.

According to a third aspect of the present invention, there is provided a curved wall structure in which a top wall and a bottom end of the wall surface are provided with a headstock and a drainer, respectively, which are made of the plate-like building material for a curved surface according to the second aspect.

[Action]

 The plate-like building material for curved surfaces according to claim 1, wherein the horizontal surface and the fixed mounting surface are formed on the upper and lower ends of the curved wall plate portion so that a horizontal surface and a fixed mounting surface can be formed by bending. Although a slit is provided in the wall plate, even if the support strength between the horizontal surface and the fixed mounting surface with respect to the wall plate part is reduced by this, the reinforcing member provided near the upper and lower ends of the wall plate part causes this wall plate Even if an external force is applied to the part, it is hard to be deformed, so that good shape accuracy is maintained. As a result, it is possible to reduce the manufacturing cost because the wall plate portion can be formed of a thinner plate material and can have a shape with a long length.

In the plate-shaped building material for curved surfaces according to claim 2, by inserting and inserting the end of the horizontal plane into the fitted insertion portion provided at the end of the vertical plane, the horizontal plane and the vertical plane are formed. A plate-like building material for curved surfaces is formed integrally with each other. Therefore, since it is not necessary to join them by welding, there is no need to perform correction work for thermal deformation during welding, finishing work on the welded surface, and subsequent color coloring. As a result, the shape precision is excellent and the manufacturing is easy. Moreover, since the above-mentioned connecting portion has a structure in which a plurality of plate members are folded and folded at the fitted insertion portion formed by bending, and the strength is enhanced, the shape accuracy is also improved by this.

In the curved wall structure according to claim 3, the entire structure from the upper end to the lower end of the building, that is, the head tree, the wall plate, and the drainer are formed by bending instead of welding. To be done. As a result, for example, a finish portion due to partial coloring after welding does not occur and a uniform color tone can be maintained over the whole, so that aesthetics are improved. Moreover, since the whole building can be constructed by combining building materials that are not welded, the manufacturing cost can be further reduced.
