Description

  The present invention relates to a wooden building having an assembly column and an assembly beam as a framework.

  In a wooden building by the wooden frame construction method, pillars and beams are composed of a single square bar having a large cross-sectional dimension. However, in the case of a single square bar, the maximum diameter is naturally limited, and the number of single square bars cut out from a single log is limited, so that there is a problem that the material cost becomes high.

Therefore, in Patent Document 1, a central strut portion having a rectangular cross section is disposed at the center position, and a plurality of substantially elongated plate-shaped winding strut portions are provided around the central strut portion around the central strut portion. An invention relating to a column structure of a building that is combined and arranged in a spiral manner is disclosed. And according to this invention, since the outer diameter of a support | pillar can be freely set with the assembly amount of a winding support | pillar part, it is supposed that it can apply from a small building to a big building.
Further, in Patent Document 2, a plurality of elongated wood unit materials are converged by bonding to form a hollow structure material, and a part of the hollow structure material is cut out to sequentially connect and fix other hollow structure materials. An invention relating to a wooden frame structure of a building is disclosed.

However, in the case of the invention described in Patent Document 1, since a long plate is used, there is a problem that the plate is warped. For this reason, it is necessary to use a grid plate which is difficult to warp, and an increase in cost is inevitable.
In addition, in the case of the invention described in Patent Document 2, since the elongated wood unit material is used, the unit material can be freely deformed and the problem of warpage does not occur, but the hollow structural materials are joined together. When doing this, it is necessary to cut out a part of the hollow structure material.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a wooden building including an assembly column and an assembly beam that can be easily constructed at low cost.

In order to achieve the above object, the present invention provides a wooden building having an assembly column and an assembly beam composed of a plurality of bars having the same cross-sectional shape as a framework, and the assembly column and the assembly beam are respectively It is composed of a main material made of the bar material arranged in parallel with an interval corresponding to the width of the bar material in two orthogonal directions, and a secondary material made of the bar material arranged between the main materials, The sub-materials are characterized by being alternately stacked in a perpendicular direction so as to form a lattice when viewed from the material axis direction of the main material.
