Recently, there has been a lot of research into roofs for houses, factories, gymnasiums, etc., where even the eaves of the roof are formed into a curved shape and are formed integrally with the general part (middle part) of the roof.
being developed. This is mainly due to the fact that if only the eaves end is connected using a separate member, the construction of this connection will be troublesome and the construction cost will be relatively high. This is to improve the problem that rainwater easily enters through the roof, causing leakage.

However, tile stick roofs are constructed from roofing boards, solid wood, capping materials, etc., and are still widely used throughout the country because they have a simple structure with few components and can be done at low cost. The research theme was to make the eaves of the building particularly simple to ensure rain protection and to construct at a low cost.

〔Effect of the invention〕

First, in the invention of claim 1 (first invention), arc-shaped bulges 2 are provided on both sides of the main plate 1.
2, rising portions 3, 3 are formed from the outer ends of both arcuate bulging portions 2, 2, end edges 4, 4 are formed inwardly from both rising portions 3, 3, and these longitudinal sides are formed. A curved building board A is formed by forming a part or the whole of the direction into a curved shape when viewed from the side, and a large rib 1a substantially orthogonal to the longitudinal direction of the main board ₁ of the curved part A1 of the curved building board A. . A curved piece of wood B is inserted and fixed onto the base material 7, and the edges 4, 4 of the piece of wood B and the adjacent curved building boards A are fitted with a cap material C. By creating a curved roof in which the edges 11, 11 and the edges 4, 4 of the curved building boards A are tightened, firstly, the eaves part and the general part of the tile stick roof can be integrated. , or the entire roof is formed integrally,
In particular, the configuration is simple, construction is simple and quick,
As a result, the number of construction days can be shortened, construction costs can be significantly reduced, secondly, it is also better in terms of prevention of leakage, and thirdly, it is possible to reliably prevent the plate ringing phenomenon.

To explain in detail the points that can be taken to prevent leakage, the main reason is that the eaves and general parts of the roof are integrated, so even if an ice bank forms on the roof after construction and water accumulates, the connecting part will not be damaged. To provide a curved roof that is extremely difficult to allow rainwater to enter, can reliably prevent leakage, and can reliably shut off rain. Furthermore, in the present invention, the large ribs _1a , 1a, . Large rib 1
The valleys of a, 1a, . Furthermore, the presence of the large ribs 1a, 1a, . . . increases the section modulus, and as a result, the strength of the curved building board A itself can be strengthened. The present invention is a roof with tile sticks using Sanki B, which is relatively simple in construction, and also includes conventional materials, so that it can be used in large demand as a curved roof.

In addition, by adding arcuate bulges 2, 2 to both sides of the main plate 1 to form a curved building board A, when forming the curved building board A into a curve, the main board 1 at the bottom has a maximum Compressive bending stress is generated, but in the present invention, due to the presence of the arcuate bulging parts 2, 2, the rising parts 3, 3 on both sides are formed in such a way that they are lowered, reducing the maximum compressive bending stress. At the same time, compressive stress and strain can be absorbed here.
Curving is extremely smooth, and the desired curve can be formed neatly and reliably. Furthermore, the arcuate bulge 2 has the advantage that it can be used as a storage space for a bolt head.

Next, in the invention of claim 2 (second invention), a protruding strip 5 is added to the middle of the main plate 1 to form a curved building board A, with respect to the configuration of the first invention. By placing and fixing the dovetail hanger D on the base material 7 and dovetailing the protruding strips 5 of the curved building board A to the dovetail hanger D, a curved roof was formed. In addition to producing the same effects as the first invention, it can be made particularly strong against wind pressure loads. That is, by dovetailing the protruding strip 5 at the middle part of the curved building board A to the dovetail hanger D, the curved building board A is attached at two locations: the tightening part and the dovetailing part. It can be made even stronger in terms of strength. For this reason, even if the thickness of the curved building board A is thin, it can have sufficient strength.

In addition, if the intermediate arcuate bulges 6, 6 are formed on both sides of the intermediate protruding strip 5 of the main plate 1 of the curved building board A, the bottom part of the curved building board A can be formed into a curved shape. The maximum compressive bending stress is generated in the main plate 1, but in the present invention, the presence of the intermediate arcuate bulges 6, 6 causes the rise of the protruding strip 5 in the same way as the presence of the arcuate bulges 2, 2. The shape is formed in such a way that the part is lowered, which acts to reduce the maximum compressive bending stress, and can absorb the compressive stress strain here, so that the curve can be formed in an orderly and reliable manner. Furthermore, the intermediate arcuate bulge 6 can also be used as a storage space for the bolt head.
