Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a structure in which the middle of a wide construction board is fixed with bolts, but the bolts are not exposed to the outside, and the appearance is extremely elegant. The present invention relates to an intermediate mounting structure for a construction board that can increase the durability of its bolts.

[Conventional technology and its problems]

Traditionally, construction boards for wall or roofing materials, etc.
Various types exist. By the way, if the width of the construction board is narrow, the strength of the middle part can be almost ensured, but if the outer enclosure such as a roof or wall is constructed using the narrow construction board, there will be many connection points. Not only does the connection 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 we make the construction board wider to increase the working width ratio, this will result in strong wind pressure (negative pressure).
When this is added, the intermediate part generally becomes particularly weak, and the plate cracking phenomenon occurs, although this is also related to the plate thickness. 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 infiltrating through the bolts.

[Means to solve the problem]

Therefore, the present invention forms a groove part in the middle of a construction board, provides rising parts on both sides of the bottom part, and inserts and mounts a hanger of an appropriate length with a locking part formed on both rising parts into the groove part. The bottom of the hanger is fixed to the structural material with bolts together with the bottom piece of the groove, legs are provided on both sides of the top piece, and a long cap material with locking parts formed on the legs is hung. By fitting the locking part into the locking part, the bolts are not exposed to the outside even in a structure where the middle of a wide construction board is fixed with bolts, and the appearance is improved. can be done very gracefully,
The durability of the bolt can be increased, watertightness (rain protection) can be improved, and the above-mentioned drawbacks can be solved.
