Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall panel, and can be used as an inner wall of a building or a partition wall.

[0002]

BACKGROUND ART A general wall panel used as an inner wall or a partition wall in a building such as a house is formed by attaching a face material such as a plaster board to a base material made of wood, for example.

[0003]

By the way, it is difficult to consume a large amount of wood due to recent forest protection movements, etc., and the price thereof is increasing. For this reason,
The conventional wall panel using wood as the base material has a problem that the price of wood is high and the overall price is high.
And, it has been desired to develop a wall panel using a cheap base material instead of wood. On the other hand, there is known a particle board or the like in which wood chips produced in the paper manufacturing industry, lumber manufacturing industry, etc., that is, waste wood chips are thermocompression molded using an adhesive. Since this particle board and the like use a large amount of waste chips, the supply is stable and the price is low.

An object of the present invention is to provide a wall panel that can be produced at a low cost.

[0005]

A wall panel according to the present invention is a wall panel formed of a base material and a face material attached to the base material, and the base material is formed of wood chip compression material. It is characterized by.

[0006] In this wall panel, a wood piece compression material is attached to the face material while one of both sides of the wood piece compression material is in contact with the face material and the other is attached in an exposed state, and the other wood surface is attached. May be provided with a non-moisture permeable member for preventing absorption of water from the surface of the wood. Further, in this wall panel, the wood piece compression material may be arranged in an exposed state in which the vertices on both sides of the wood piece compression material are orthogonal to the plane of the face material. In this case, a plurality of wood piece compression materials may be stacked. . A moisture-impermeable member that prevents absorption of water from the wood mouth surface may be provided on the wood mouth surface on both sides of the wood piece compression material.

[0007]

According to the present invention as described above, the base material forming the wall panel is formed of wood piece compression material, and the wood piece compression material is stable in supply and cheap in price, so that the base material is also inexpensive. Panels can be produced at low prices.

Further, in this wall panel, when a moisture-impermeable member is provided on the other mouth end of the wood chip compression material attached to the face material, absorption of water from the other mouth end is prevented. As a result, it is possible to prevent the compressed wood piece from being bent back and deformed due to twisting.

Further, in the case where the compressed wood pieces are arranged such that the vertices on both sides of the compressed wood pieces are exposed so as to be orthogonal to the plane of the face material, even if moisture is absorbed from the xylems on both sides. , The average of the whole is compressed wood chips,
As a result, the occurrence of deformation of the compressed wood piece caused by warping or twisting due to an imbalance of water absorption is reduced, so that it is not necessary to provide, for example, a non-moisture permeable member on the exposed wood surface, and Eliminates the need for installation. However, if non-moisture permeable members are provided on both sides of the wood mouth according to the environment in which the wall panel is used, absorption of water from these wood mouth surfaces is prevented. Deformation due to twisting can be prevented.
When a plurality of compressed wood chips are stacked, the thickness dimension can be secured by stacking a plurality of compressed wood chips, so even a thin compressed wood chip can be sufficiently used as a base material.
