Description

[0001]
[Industrial application fields]
The present invention relates to construction of a wall panel material constituting a wall portion of a building, and particularly relates to a wall panel joint structure excellent in workability, strength, drainage and the like.
[0002]
[Prior art]
Conventionally, various building materials exist in the wall part of a building, and construction according to each building material is performed. In recent years, many wall panel materials have been used as building materials. The wall panel material is also formed in a flat box shape, and the inside is filled with a heat insulating material, a fireproof material (refractory material) or the like.
[0003]
A large number of such wall panel materials are prepared and attached to a structural material such as a trunk edge via a fixing tool such as a screw. In addition, a cap member for closing the joint is installed between the wall panel materials adjacent in the horizontal direction, the vertical direction, etc., and the fixing tool such as the screw is hidden from the outside, or rainwater is inserted between the wall panel materials. I try not to get inside.
[0004]
[Problems to be solved by the invention]
By the way, in order to attach the cap material between the adjacent wall panel materials as described above, conventionally, the cap material is pushed into the gap between the wall panel materials, and the small protrusion formed on the side portion of the wall panel material. The cap material is fixed by fitting the cap material and the like. However, according to the above structure, the cap material cannot be fixed with an appropriate fixing force unless the predetermined dimension in the width direction of the cap material and the interval between the adjacent wall panel materials are accurately determined. .
[0005]
However, in many arranged wall panel materials, it is extremely difficult to make all the intervals between adjacent wall panel materials exactly the same, and some errors always occur. For this reason, when the cap material is installed, if the distance between the wall panel materials is slightly wider than the specified size, the cap material is too loose to be installed, and vice versa. Can not fit. For this reason, a small protrusion or the like is formed on the side surface of the wall panel material and is fitted and fixed to the cap material, but it is difficult to obtain an appropriate mounting strength even with this structure. .
[0006]
[Means for solving the problems]
In view of the above, the inventor has intensively and researched to solve the above-mentioned problems, and as a result, the present invention has a side portion formed at a substantially right angle from both ends in the width direction of the main plate, and a cross section is substantially formed at the lower end of the one side portion. A folded groove-shaped portion is formed, a substantially horizontal upper connecting piece is formed from the other end of the groove-shaped portion, and a substantially horizontal lower connecting piece is formed at the lower end of the other side portion. A wall panel material is provided, and an upper connection piece and a lower connection piece of adjacent wall panel materials are joined, a cap fixing member is mounted on the upper connection piece, and between adjacent wall panel materials via the cap fixing member By adopting a wall panel joining structure formed by attaching a cap material, construction efficiency is excellent, construction finish, durability, drainage, etc. are good, and the above-mentioned problems are solved.
