2. Description of the Related Art Conventionally, in the construction of houses, particularly in cold regions, the construction method of a house with a high airtightness and a high heat insulation structure has been carried out. Due to the difference in temperature and humidity between the core and the inside of the core, the building material molded from wood may be warped due to internal stress. In order to prevent such warpage, it is common practice to form cuts or grooves in the building material. On the other hand, in the laminated material, the laminated material is formed by overlapping the front and back in consideration of internal stress in advance, and there is no risk of warpage due to internal stress, but the temperature difference between the surface and the inside of the core, humidity The difference may cause a warp.

[0003]

SUMMARY OF THE INVENTION In view of the above, the present invention can prevent warpage by providing a plate or a square bar with a structure that does not cause a temperature difference and a humidity difference between the surface and the inside. At the same time, it provides a building structure element having heat insulation and air permeability by convection of air.
