DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an architectural panel which is useful as an outer wall, an inner wall, and a partition wall of a building or a building and has a high waterproof property.

[0002]

2. Description of the Related Art In general, a box-shaped building panel having a decorative surface projected thereon is formed by connecting and fixing the fixing pieces to each other and attaching the fixing piece to a base through a fixing tool. The joints are filled with a sealing material or the like to improve waterproofness.

[0003]

However, if the fixing pieces are simply overlapped with each other as in the case of the conventional building panel, the sealing material is not properly applied or the sealing material is broken or cracked due to deterioration over time. Then, when rainwater infiltrates from the gap, rainwater infiltrates the inside of the building panel and the groundwork from the gap of the overlapping of the fixed pieces,
There was a problem that corrosion and rain leakage occurred.

[0004]

According to the present invention, in order to eliminate such a drawback, a sheet-like waterproof packing material is integrally mounted on at least two adjacent fixing pieces of the four fixing pieces. Therefore, when the fixing pieces are overlapped when connecting the building panels, the waterproof packing material always intervenes in the joints, and we propose a building panel that greatly improves the waterproofness of the joints. is there.

As shown in FIG. 1, the waterproof packing material B utilizes self-adhesiveness on at least two adjacent fixing pieces 4 among the four fixing pieces 4 of the building panel A. Alternatively, using an adhesive (not shown), it is fixed at the factory shipping stage.

As shown in FIG. 2, the waterproof packing material B is attached to at least two adjacent fixing pieces 4 of the four fixing pieces 4 of the building panel A so as to be adjacent to each other. When the fixing pieces 4 of the building panel A are overlapped and connected to each other, the waterproof packing material B is all located at the joint α, and the waterproof performance of the joint α is greatly improved.

More specifically, FIGS. 3 (a) and 3 (b) are enlarged explanatory views showing a cross section of the joint portion α of the connection, and FIG. 3 (a) shows that the waterproof packing material B is not bonded. FIG. 3B shows the structure of the joint portion α in which the fixing piece 4 to which the waterproof packing material B is adhered is laid on the fixing piece 4, and FIG. This is a structure of the joint portion α in which the fixing piece 4 to which the waterproof packing material B is not bonded is overlapped on the piece 4.

3A and 3B, more than one waterproof packing material B is present at the bottom of the joint portion α, so that rainwater can be prevented from entering from the joint portion α. .

The fixing of the building panel A is performed by screwing screws from the stacked fixing pieces 4 toward the wall foundation C.
The architectural panel A is fixed to the wall foundation C by driving in a fixture D such as tex. Further, the subsequent processing of the joint portion α is performed by filling the backup material E and the sealing material F to enhance the waterproofness and design of the joint portion α.
