Description

[Detailed Description of the Invention] The present invention relates to a wall panel used for internal and external walls, partition walls, etc. of structures such as mid-to-high-rise residences and buildings.

In recent years, with the spread of dry construction and fireproof construction of building structures, construction materials made of inorganic materials such as asbestos cement boards, asbestos calcium silicate boards, and gypsum boards are being used for the interior and exterior walls, partition walls, ceilings, etc. of buildings. is widely used because it has excellent properties that meet the above objectives.

However, these building materials made of inorganic materials are generally installed at designated locations on a structure due to architectural structural issues or aesthetic requirements, and then the surface is given a decorative finish by painting, adhering a different material, etc. Decorative plywood is often used, in which an inorganic building material is used as a substrate and a different material such as a vinyl chloride sheet, tile, or metal plate is pasted on one or both sides.

In all of the conventional construction materials using inorganic materials as substrates, care has been taken to ensure that the decorative layer applied to the surface sufficiently adheres and integrates with the substrate, but due to the density difference between the material of the substrate and the foreign decorative layer. There are drawbacks such as non-uniform warping due to contraction and expansion, and delamination between the substrate and the decorative layer.

The present invention was proposed in order to solve such problems, and the surface is formed into an angular wave shape, and through holes 2 are bored at predetermined intervals in the grooves 1a, and through cavities 3 are formed. On the surface of an extrusion molded base plate A made of an inorganic material such as asbestos cement,
A square wave-like heterogeneous decorative board B made of a metal plate or the like is fitted, and a locking fitting 5 vertically installed on the lower surface of the groove 4a of the decorative board B is connected to the groove 1 in the base A.
The wall panel is characterized in that the tip of a locking rod 7 that fits into the through hole 2 of a and passes through the bottom piece 6 of the base plate A is engaged and tightened with the locking fitting 5. It is something.

Incidentally, the groove 1a and the protrusion 1b adjacent thereto in the base plate A, and the groove 4a and the protrusion 4b adjacent thereto in the decorative board B are all formed in a trapezoidal cross section, and the through-hole The cavity 3 is the concave groove 1a of the base plate A.
The ridge portions 1b and 1b are each formed to have a rectangular cross section and a substantially trapezoidal cross section. Furthermore, grooves 8a and protrusions 8b that engage with the grooves 8a are provided at both ends of the base plate A, so that the base plate A is joined in the lateral direction.

Further, the locking metal fitting 5 is formed into a spiral cylinder, for example,
The tip of the locking rod 7 formed on the screw rod is screwed and tightened.

As mentioned above, the wall panel according to the present invention is formed into a square wave shape so that the surface of the base plate A and the decorative board B bonded to the same surface match each other.
The entire wall panel is strengthened, and the through-hole 3 of the base plate A provides effects such as sound insulation and heat insulation.

Further, the locking metal fittings 5 vertically installed on the lower surface of the grooves 4a of the decorative board B are connected to the grooves 1 of the base plate A.
The base plate A and the decorative plate are connected by engaging and tightening the locking rod 7 which fits into the through hole 2 bored in the base plate A and passes through the bottom piece 6 of the base plate A to the locking metal fitting 5. Since A and B are partially joined, deformation and peeling phenomena caused by the difference in thermal expansion between A and B are absorbed, and there is no change in performance as a wall panel.

Further, according to the present invention, the base plate A and the decorative laminate B are joined by tightening the engaging tool 5 and the locking rod 7 without using an adhesive, and edge treatment of the surface decorative laminate B is performed. It is easy to manufacture because it does not require complicated processes such as The present invention has many advantages, such as that it does not spoil the appearance.
