Description

  The present invention relates to the structure of a new wooden building.

  The structure of a conventional wooden building is a wooden frame structure with pillars, beams and foundations as axes, or a wooden framed wall structure with a combination of multiple flat plates as a surface (2 × 4 structure) ) Is common.

  The wooden frame structure is a traditional structure used in most wooden buildings in Japan. It is a structure in which various pillars are used as vertical trees and foundations and beams are assembled as horizontal trees. The shaft supports the load from above. Then, floors are formed by laying flooring or the like on these shafts. As described above, the wooden frame structure is assembled with linear wood, so that there are few structural restrictions, and the degree of freedom in floor plan and design is high.

  On the other hand, the wooden frame wall structure is often used in the United States and the like, and is a structure in which a frame is made using a specified wood and a box is made with a wooden panel on which plywood is pasted. Whereas the wooden frame structure is an “axis”, it is composed of “faces” and is supported by a wall instead of a pillar and a floor or ceiling instead of a beam. Compared to a wooden frame structure, the construction is relatively easy and the construction period is short regardless of the skill of the craftsman.

  As described above, the conventional wooden frame structure has a few structural restrictions and a high degree of freedom in floor plan and design, but there is a problem that construction is difficult and depends on the skill of the craftsman. Also, the construction period is relatively long. On the other hand, the wooden framed wall structure is relatively easy to construct and does not depend on the skill of the craftsman, while the construction period is short, but there is a problem that the degree of freedom is low due to restrictions. In addition, the wooden frame structure is hardly affected by the skill of craftsmen, but in Japan, the wooden frame structure is the mainstream, so there is a problem that there are still few craftsmen who can handle this construction.

  An object of the present invention is to provide a new structure of a wooden building that is easier to construct than a conventional wooden frame structure, has a shorter construction period, has less restrictions and has a higher degree of freedom than a wooden frame wall structure.

  The structure of the wooden building according to one aspect of the present invention includes a first flat plate portion configured by arranging long plates extending in the first direction and a long plate extending in the second direction orthogonal to the first direction. And a plurality of column members having protrusions for joining the plate members at the ends, and the plate members are protrusions of the plurality of column members. Each of which has a plurality of holes to be fitted, and the plate material is attached above the plurality of column members by fitting the protrusions into the holes, and the first flat plate portion of the plate material functions as a beam. The second flat plate portion functions as a joist.

  According to this structure, the vertical wood in the conventional wooden frame structure uses a pillar as it is, and the first flat plate portion configured by a long plate extending in the first direction of the plate material as a horizontal wood such as a beam bears the conventional structure. Although it fits within the framework of the wooden frame structure, it is possible to reduce the construction work and shorten the construction period by eliminating the need for horizontal members. In addition, the second flat plate portion constituted by a long plate extending in the second direction of the plate material bears the joist which is the shaft of the floor in the conventional wooden frame structure, and the easiness of construction and the construction period can be achieved even if the joist is unnecessary. Is shortened.

  In addition, this structure fits within the framework of the conventional wooden frame structure, so it is relatively easy for Japanese craftsmen to handle. Furthermore, by replacing the horizontal wood with a plate material, improvement of the sound insulation performance of the floor and improvement of in-plane shear rigidity can be expected.
