[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a unit type woodwork building material useful for building bungalows, wooden houses, etc., and is mainly used for insect damage prevention of buildings and simple construction, and can prevent deformation and cracks of materials. It is what

[0002]

[Prior art]

 Generally, wood has a high specific strength and a high specific elastic modulus, is excellent in moisture absorption and desorption, is excellent in heat insulation, and has a well-established reputation for its color tone, scent, and texture, and is widely used in the construction of bungalows and ordinary houses.

Conventionally, when building a bungalow or a general house using this wood, in order to prevent the deformation of the skeleton between the pillars, the plywood and the wood grain materials are attached to the standing pillars. I am making a mistake.

On the other hand, in a so-called log house formed by combining logs in a cross beam shape, raw logs are mainly used, and dowels are fitted to the connecting portions to prevent mutual displacement. .

[0005]

[Problems to be solved by the device]

 However, the conventional wooden structures described above have the following drawbacks.

[0006] First, there is a drawback that the work of sequentially laminating plywood and grain material between columns is very difficult and cumbersome.

Further, when plywood is used, there is a drawback that breathability is extremely deteriorated and the original color and touch of wood cannot be utilized, which adversely affects habitability.

[0008] On the other hand, the use of a wood grain material has a drawback in that it deforms such as warping in the horizontal direction and loses its aesthetic appearance.

Secondly, a log house using raw logs has a drawback that deformation, deformation, cracking and the like occur after construction, resulting in remarkable deterioration of aesthetics and strength.

[0010] It is well known that wood, especially sapwood, causes insect damage due to beetle, beetle, or termites. It is well known that insect repellent is applied at the time of construction. The reality is to prevent this.

The present invention has been made in view of the above circumstances, and is mainly intended to prevent insect damage to wooden buildings and simple construction, and to prevent deformation and cracks of materials.

[0012]

[Means for Solving the Problems]

 According to the present invention, the sides of the square grain-shaped perforated grain mainly composed of cedar heart are exposed as the upper and lower sides, and grooves are formed on the upper and lower sides of the perforated grain respectively in the longitudinal direction. In addition, a unit-type woodworking building material is provided in which the wood grain materials are sequentially connected through insect-resistant square wood fitted in the groove, and bolts are passed through the wood grain from the upper end to the lower end. Thus, the above-mentioned problems are achieved.

[0013]

[Action]

 According to the unit type woodworking building material of the present invention, the square wood fitted in the groove of the wood grain prevents the lateral shift of the wood grain, and by making this wood cypress or hiba, the termite repelling effect is obtained.

On the other hand, the pierced bolts are used to fix the present building material, function like a brace, and resist the horizontal force due to wind or earthquake.

Since this grain material is connected and arranged so that the grain surface is exposed on the vertical surface, it does not warp or deform in the horizontal direction, and the force of bending back in the vertical direction. Will be restrained by the grain lines arranged in that direction, or by girders and bases.
