Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exterior face plate for a building, which does not generate waves on the flat portion of the roofing material during construction of the roofing material or during long-term use, and maintains a beautiful finish. And the roof for buildings.

[0002]

2. Description of the Related Art Conventionally, a roof plate used for a thatched roof has a shallow groove-like structure in which the left and right edges of a vertically long plate material are raised along the slope of the roof. Things were being used. And, in the seam-welded waterproof roof using the above-mentioned vertical roofing board, by connecting the end of the roofing board to the end of the adjacent roofing board via a connecting member such as a roof tile, in the lateral direction. The roof boards were installed side by side.

[0003]

However, in the above-mentioned roof, while the end portion of the roof plate is rapidly heated or rapidly cooled by the welding operation, the central portion (face plate portion) of the roof plate is
Since these effects are not suddenly exerted on the face plate, a longitudinal compressive stress acts on the face plate portion of the roof plate.
Therefore, when the thickness of the face plate portion of the roof plate is thin and the strength thereof is low, the face plate portion elastically buckles due to the above-mentioned compressive stress to generate a wave, resulting in a very poor appearance. In addition, in its use, the end of the roof plate is covered with a tiled roof etc. so that it is hard to receive the radiant heat of the sun, but the face plate part of the roof plate is likely to reach a high temperature due to the radiant heat of the sun. The amount of expansion increased and generated waves, which significantly impaired aesthetics.

As a method for preventing the above-mentioned generation of waves, a method of absorbing a compressive strain by attaching a corrugate in the width direction to the face plate portion of the roof plate, or providing a longitudinal rib in the face plate portion to improve the cross-sectional performance, There is a method of making it difficult to elastically buckle. However, since each of the above-described methods processes a face plate portion that is invisible, a new aesthetic problem arises. For example, even if the surface is beautifully cleaned or subjected to a treatment such as painting, the above-mentioned processing causes scratches or damages on the surface or the coating film, so that polishing, washing, painting, etc. It becomes necessary to perform processing. Therefore, there has been a demand for an effective method for preventing the generation of waves due to elastic buckling while keeping the face plate portion smooth without giving unevenness or the like.

[0005]

SUMMARY OF THE INVENTION The present invention has been proposed in view of the above, and an exterior face plate including a substantially flat face plate portion and side edge portions provided on the left and right of the face plate portion is used as a roof substrate. The present invention relates to an exterior face plate for a building, wherein a pre-strain in the longitudinal direction is applied to the face plate portion so that a tensile stress in the longitudinal direction acts when the face plate is laid.

The present invention also proposes a building roof characterized in that the above-mentioned exterior face plate for building is laid along a roof substrate.

[0007]

Since the present invention has the above-described structure, the prestrain is applied so that the tensile stress acts even when the compressive stress due to the radiant heat of the sun acts during the welding process during the assembly or during the use. Since they are applied, these stresses do not cancel each other to generate a wave. Specifically, the prestrain is completely different between the exterior face plate whose face plate portion is located below the neutral plane and the exterior face plate whose face plate portion is located above the neutral face. In general, since compression deformation occurs on the inner side of the bend with respect to bending and extension deformation occurs on the outer side of the bending, the exterior face plate located below the neutral face and the face plate are neutral. A pre-strain that conflicts with the exterior face plate positioned above the surface will be given.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the embodiments of the drawings. Roof mounting base 1 as shown in FIGS.
The exterior face plate 2 to be laid in is formed in a vertically long shape so as to follow the slope of the sloping roof mounting base 1, and has a shallow groove shape in which side edges 4 and 4 are provided on the left and right of the face plate part 3 having a substantially flat shape. is there. In addition, the exterior face plate 2 in which the face plate portion 3 is located below the neutral surface N and the exterior face plate 2 in which the face plate portion 3 is located above the neutral surface N
Since the method of applying pre-strain is also different in each case, each will be described, but for convenience of description, the former will be referred to as the lower surface plate member 2A.
_N (the face plate portion 3A _N , the side edge portion 4A _N ) and the latter is referred to as the upper surface plate member 2B _N (the face plate portion 3B _N , the side edge portion 4B _N ).

First, as shown in FIG. 1, when laying the lower surface plate material 2A on a roof whose roof mounting base 1 is a flat surface, the lower surface plate material 2A ₁ previously formed in a convex direction is used, and it is placed at an appropriate position. It is laid on the roof mounting base 1 with a fastening material (not shown) or the like. In addition, when laying the top plate 2B on this roof, the top plate 2B ₁ formed in a downward convex direction in advance is used, and it is laid on the roof mounting base 1 with a fastening material (not shown) at an appropriate place. To do. The bottom plate member 2 thus prestrained
A ₁ and the top plate 2B ₁ are face plate portions 3A ₁ and 3B, respectively.
Tensile residual stress acts on ₁ .

FIG. 4 shows a roof in which the roof mounting base 1'is convex upward. First, when laying the lower surface plate member 2A, using the lower surface plate 2A ₂ molded with greater curvature than previously roof mounting base 1 '. Further, when laying the upper surface plate 2B, pre-roof mounting base 1 top plate 2B ₂ was molded into a smaller curvature than the curvature of ', or in advance flat on molded top plate 2B ₃ or preformed in the direction of the downwardly convex The upper surface plate material 2B ₄ is used.

FIG. 5 shows a roof in which the roof mounting base 1 "is downwardly convex. First, when laying the lower plate 2A, the curvature is smaller than the curvature of the roof mounting base 1" in the downward convex direction in advance. The lower surface plate material 2A ₃ formed in a curvature, the lower surface plate material 2A ₄ formed in a flat shape in advance, or the lower surface plate material 2A ₅ formed in an upward convex direction in advance is used. Also, the top plate 2B
When laying, the roof mounting base 1 "in the downward convex direction beforehand
The upper surface plate member 2B ₅ formed with a larger curvature is used.

As described above, according to the present invention, no wave is generated by pre-straining the face plate portion so that tensile stress acts on the roof of any shape and laying it on the roof mounting base. The roof can be constructed.

In addition, the left and right side edge portions 4 and 4 of the exterior face plate 2,
The connection structure is not particularly limited, and for example, as shown in FIG.

[0029]

In summary, according to the present invention, tensile stress acts on the face plate portion regardless of whether the face plate portion is above the neutral surface or the face plate portion is below the neutral surface. By pre-straining and laying it on the roof mounting base, it is possible to construct a roof that does not generate waves even after long-term use.

Therefore, the roof laid by the exterior face plate as described above has a beautiful finish because the face plate portion does not have the ribs and corrugates as in the conventional case. Further, since it is not necessary to process the above-mentioned visible face plate portion, the surface or the coating film on the surface is not scratched or damaged.
