Description

[Detailed Description of the Invention] The present invention relates to a connection structure for building boards, and more specifically, a fitting U-shaped portion 2 that opens laterally is formed on one side of a building board 1. The back piece 3 of the U-shaped part 2 is extended laterally than the front piece 4, and an elastic body 5 is attached to the entire back surface of the front piece 4 of the U-shaped part 2 for fitting. The side plate 1b is bent backward at the side, and a fitting convex portion 6 is provided laterally protruding from the outer surface of the side plate 1b on the rear side of the side plate 1b.
A protrusion 10 that is softer than the outer surface of the side plate 1b is provided on the front side of the side plate 1b, and a small protrusion 7 is provided on the front side of the tip of the fitting protrusion 6,
The fitting convex portion 6 of the adjacent building board 1 is fitted into the fitting U-shaped portion 2 of the building board 1, and the elastic body 5 in the fitting U-shaped portion 2 is inserted.
The small protrusion 7 of the fitting convex part 6 is bitten into the abutting part 12 extending rearward from the tip of the side plate 1b of the building board 1 adjacent to the front side of the back piece 3 of the U-shaped part 2 for fitting. This relates to a construction board connection structure in which the protrusions 10 are brought into elastic contact with the sides of adjacent construction boards 1 by pressing.

In the conventional construction board connection structure, a U-shaped fitting part 2' is provided on one side of the building board 1', and a fitting convex part 6' is formed on the other side of the building board. Since the fitting convex part 6' of the adjacent building board 1' was simply fitted into the fitting U-shaped part 2' of the building board 1', the building board 1' easily slipped and the connection was difficult. There was a problem that there were gaps in the parts.

The present invention has been devised in view of the above points, and its purpose is to provide a connection structure for architectural boards that is less likely to shift at the connecting portions of the architectural boards.

Hereinafter, the present invention will be explained in detail based on examples.

The architectural board 1 is formed by filling a rigid urethane resin 9 into a substrate 8 made of a rigid vinyl chloride resin.

A U-shaped part 2 for fitting is formed on the back of one side plate 1a of the architectural board 1 over the entire length, and the back piece 3 of the U-shaped part 2 for fitting is extended laterally than the front piece 4. An elastic body 5 made of soft vinyl chloride resin is attached to the back surface of the front piece 4 of the U-shaped part 2 for fitting.

A fitting protrusion 6 is provided laterally over the entire length from the other side plate 1b of the construction board 1, and a small protrusion 7 is provided on the front surface of the fitting protrusion 6 over the entire length. A protrusion 10 made of soft vinyl chloride resin protrudes laterally from the front part of 1b over the entire length.

When connecting the architectural boards 1 to each other, as shown in FIG. 3, the fitting convex part 6 of the adjacent building board 1 is fitted into the fitting U-shaped part 2 of the building board 1, The small protrusion 7 of the fitting convex part 6 bites into the elastic body 5 in the U-shaped fitting part 2, and the rear end of the side plate 1b of the architectural board 1 is fitted with the elastic force of the elastic body 5. It is pressed against the back piece 3 of the U-shaped part 2,
Also, the protrusion 10 is pressed onto the side plate 1a.

As a result, the small protrusions 7 bite into the elastic body 5 to prevent the building board 1 from shifting laterally, and no gaps are created at the joints, and the building board 1 is connected by crimping the protrusion 10 to the side board 1a. This improves the watertightness of the area.

As described above, the present invention forms a U-shaped part for fitting on one side of the architectural board, and attaches an elastic body to the entire back surface of the front piece of the U-shaped part for fitting. A side plate is bent backward on the other side, a fitting convex part is provided on the rear side of the side plate, and a soft protrusion is provided on the front side of the side plate. Insert the fitting convex part of the adjacent architectural board into the fitting U-shaped part of the board, and press the small protrusion of the fitting convex part into the elastic body in the fitting U-shaped part. Since the front side of the back piece is pressed against the abutting part extending rearward from the tip of the side plate of the adjacent building board, the abutting part of the other adjacent building board is pressed against the fitting part of one building board. As a reaction to the force that presses the front side of the spine of the character-shaped part, the small protrusions bite into the elastic body of the building board, preventing mutual displacement of both building boards and ensuring that the building board is securely attached. There is an advantage that it is possible to connect the small protrusions and to ensure watertightness between the small protrusions and the elastic body.

Moreover, since a soft protrusion is provided on the other side of the construction board and the projection is made to come into elastic contact with the side of the adjacent construction board, this protrusion can also be used to connect the two construction boards. Even if there is a slight error in the protrusion dimension of this protrusion, the elastic body is attached to the entire back surface of the front piece of the U-shaped mating part, so that the small protrusion can be improved. It has the advantage of good watertightness because it reliably bites into the elastic body.
