[0002]

2. Description of the Related Art Conventionally, printed plywood has been mainly used as a building material for forming floors and walls of buildings. This is because the plywood material has advantages such as relatively high hardness and uniformity, small dimensional distortion even after a lapse of time after joining work, and good workability during the work.

Heretofore, as a method of joining building materials to floors, walls, and the like of a building, a ridge method and a phase joint method are known. However, the tongue method is considered to be advantageous from the viewpoint of preventing steps such as floors. This is because the phase joint method usually uses an adhesive at the joint, and if the amount of the adhesive applied is insufficient, poor adhesion occurs at the joint, and if the amount of the adhesive is too large, the floor board rises and the step Is caused. One tongue method is a plate material in which a concave portion called a female ridge is formed at one end of the plate material in the joining direction and a convex portion called a male ridge is formed at the other end. It is to be attached in the direction of the end face convex part so that the convex part and the concave part are fitted together, and nails the diagonally from the upper surface side base of the end face convex part of the plate material to fix the plate material to the joist material. Then, the nailed end surface convex portion is attached so as to fit a concave portion of another plate material, and the nailing and the fitting are sequentially repeated. Therefore, according to this tongue method, since the concave portion and the convex portion of the plate material are fitted to each other, there is little trouble that a step is generated due to the floating of the plate material.

[0004]

As described in the background of the invention, printed plywood is the mainstream for building floors and walls of buildings. Sick house syndrome, which complains of headache, diarrhea, eczema, and pain in the eyes and throat, has become more frequent. Thus, as the cause of the sick house syndrome has been investigated, it has been found that the cause is due to chemical substances such as formaldehyde and preservatives contained in adhesives used for housing building materials and furniture. For example, adhesives and preservatives for printed plywood and wallpaper contain formaldehyde, a volatile chemical, and paints such as paint and lacquer contain toluene and xylene, which are volatile chemicals. ing. And these volatile chemicals cause eye and throat pain to the human body,
It has been reported that it causes symptoms such as headache, numbness of limbs, decreased visual acuity, and atopic dermatitis.

On the other hand, it is desired to form floors, walls, and the like with natural materials that do not contain volatile chemical substances. Although it has been issued, it is a soft material compared to the plywood material described above, and it tends to be shunned along the grain and causes distortion, so its use is apt to be avoided, and even in actual enforcement Inconveniences may be caused by problems due to cracks and distortion due to contraction and warpage of members as a problem with time after the operation.
