Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a wall panel that constitutes an outer wall surface of a building.

(B) Conventional technology Conventionally, this type of wall panel has a surface material 2 as shown in FIG.
1 and the backing material 22 are bonded and fixed to the reinforcing material 23 interposed between them by the adhesive materials 24 and 25, and the outer frame 26 projecting from the position of the backing material 22 is integrally formed on the peripheral edge of the surface material 21. However, the inner frame 2 extending in the direction of the front material 21 is provided on the periphery of the backing material 22.
In general, 7 is integrally formed, and a watertight material 28 is interposed and sealed between the outer frame 26 of the front material 21 and the inner frame 27 of the backing material 22. As described above, it is merely sandwiched in the space between the outer frame 26 and the inner frame 27. Therefore, when the watertight material 28 loses its elastic ability due to aging or deterioration, or when the watertight material 28 is incompletely sealed due to poor construction or the like, rainwater is lost. However, there is a defect in water-tightness and waterproofness, such as entering the room when flowing in from between the outer frame 26 and the inner frame 27.

(C) Problems to be solved by the invention The problems to be solved by the invention are that even if rainwater flows in as described above, the rainwater can be drained to the outside to prevent it from entering the room. It is intended to obtain a wall surface panel.

(D) Means for Solving Problems As a means for solving the above problems, the present invention integrally forms a peripheral frame and a back frame inwardly protruding from the peripheral frame. A front material, an open space facing the back frame of the front material, a rectangular frame projecting toward the inner surface of the front material at a portion closer to the inner side than the position where the open space is formed, and a back material mounting portion for mounting the back material. An edge material integrally formed with the water, a water drain hole opened at the lower side of the peripheral frame of the surface material, and a first watertight material that is placed in the open space of the edge material and press-contacts with the back frame of the surface material. And a second watertight material interposed between the rectangular frame of the edge material and the inner surface of the surface material.

(E) Operation Next, the operation of the present invention will be described.

Rainwater is stored in the open space of the edge material and comes into pressure contact with the back frame of the surface material. And the second watertight material interposed between the rectangular frame of the edge material and the inner surface of the surface material, the rainwater that has flowed in is received by the closed surface formed between the rectangular frame of the edge material and the inner surface of the surface material. As for the rainwater received on the closed surface, the closed surface functions as a gutter and drips from the end into the inside of the side hollow, and flows down into the inner space of the lower edge of the peripheral frame of the surface material, and the rainwater flows down. The inner space also functions as a gutter, and is drained from the drain hole to the outside.

That is, rainwater flowing in from the periphery between the surface material and the edge material passes through the closed surface formed by the rectangular frame of the edge material that functions as a gutter and the second watertight material, and the side hollow to surround the lower edge of the surface material. It flows down into the inner space of the frame and is drained to the outside through the water drain hole.

(F) Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

A peripheral frame 2 is formed on the peripheral edge of the surface material 1 at a right angle to it, and a back frame 3 is integrally formed at the tip of the peripheral frame 2 by projecting inwardly at a right angle to the peripheral frame 2. An open space 5 facing the back frame 3 of the surface material 1 is formed in the periphery of the edge material 4, and the edge material 4 projects toward the inner surface of the surface material 1 at a position closer to the inner side than the position where the open space 5 is formed. The rectangular frame 6 is formed, and the backing material mounting portion 8 for mounting the backing material 7 is formed on the inner circumference. Then, a water drain hole 9 is formed in the lower side 2a of the peripheral frame of the surface material 1.
Is opened and the watertight material 10 pressed against the back frame 3 of the surface material 1 is placed in the open space 5 of the edge material 4 to serve as the first watertight material. A watertight material 11 is interposed between the inner surface of the material 1 and a second watertight material.

(G) Effect of the Invention As described above, the present invention, when rainwater flows in from a portion where the first watertight material 10 in the periphery between the surface material 1 and the edge material 4 fails to seal, the rainwater flows into a rectangular frame. 6 and second watertight material 11
Since the water is guided from the closed surface formed by the inside of the side hollow 12 to the internal space 2b of the lower side 2a of the peripheral frame and drained to the outside, the rectangular frame 6 of the edge member 4 and the second watertight member 11 are formed.
Closed surface and side hollow by and the lower edge 2 of the peripheral frame of the surface material 1
Since "a" acts as a gutter and also has a drainage function of inflowing rainwater, it does not require a special drainage structure, so that it has an excellent practical value such that the structure is not complicated.
