Description

[Detailed description of the invention] [Field of industrial application] The present invention has a structure in which the bulging strip in the middle of a wide construction board is fixed with bolts, and the bolted part is covered with cap material. The present invention relates to a structure for attaching a cap material to a building board, which has an extremely elegant appearance, increases the durability of its bolts, and has good watertightness (rain protection).

[Conventional technology and its problems]

The applicant has already conducted various researches and developments on external enclosures such as roofs or walls that are constructed by fitting adjacent architectural boards together from the viewpoint of good workability. By the way, if the width of the construction board is narrow, the strength of the middle part can be almost ensured, but when constructing an outer enclosure such as a roof or wall using the narrow construction board, the mating part may be damaged. As a result, not only does the fitting and installation work become troublesome, but the proportion of the working width of the building board itself is small, resulting in the inconvenience that the construction cost of the enclosure becomes relatively high. Therefore, if the width of the construction board is made wider to increase the working width ratio, then when strong wind pressure (negative pressure) is applied, the middle part becomes particularly weak and the plate rattle phenomenon occurs. Ta. Then, if the middle part of the construction board is fixed with bolts, etc., the bolts will be exposed, and the bolts will corrode early, which will not only deteriorate the appearance, but also reduce the durability of the bolts. There were drawbacks such as rainwater seeping in from certain points.

In order to solve this problem, a cap material was used to cover the bolt fixing point in the middle of the construction board, but this cap material was very noticeable against the construction board and seriously spoiled the appearance. It was becoming.

[Means to solve the problem]

Therefore, the inventor worked diligently to solve the above problem.
As a result of repeated research, the present invention was developed for use in construction, in which a plurality of first grooves are formed at predetermined intervals in the longitudinal direction of the main plate, and a bulging groove with a substantially U-shaped cross section is formed approximately in the center of the main plate. The plate is placed on the structural material, the bottom of the bulging strip is fixed to the structural material with bolts, a cap material with a gate-shaped cross section is inserted and fitted into the bulging strip, and the upper ends of both sides of the bulging strip are inserted and fitted. and the pitch between the two second grooves formed by the upper ends of both sides of the cap material, or the pitch between the third groove formed between the second groove and the cap material, or the pitch between the two third grooves.
By making the pitch between the grooves approximately equal to the pitch between the two first grooves formed on the main board, the structure for attaching the cap material to the construction board allows the middle of the wide construction board to be fixed with bolts, Even with a structure in which the bolt-fixed part is covered with cap material, the appearance is extremely elegant, the durability of the bolt is increased, and watertightness (rain protection) is improved, which solves the above problems. It is.
