Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a so-called wall type structure consisting of a wooden building unit having wall panels and floor panels, and in which the wall panels are load-bearing walls.
Regarding the improvement of a story wood unit building, in particular, it is possible to form a space following the first story.

[Conventional technology]

Conventionally, a two-story wooden unit building with a so-called wall-type structure consisting of a wooden unit having wall panels and a floor panel, with the wall panels serving as load-bearing walls, has been constructed, for example, in the Japanese Patent Publication No. 61-1583.
As stated in the publication, a group of wooden building units, etc. consisting of a plurality of small wooden units each having a floor panel and a wall panel are stacked to form a two-story building, and each wooden building unit group of the first floor wooden building unit group, etc. The wall panel of each small wooden unit in the wooden building unit group on the second floor is placed above the wall panel of the small unit, and the second floor is supported by the wall panel of each small wooden unit in the wooden building unit group on the first floor. It has been known.

[Problem that the invention seeks to solve]

In the conventional unit building mentioned above, each wall panel of each small wooden unit of the wooden building unit group on the first floor is essential for supporting the second floor, and some wall panels can be removed to continue. Forming a gap poses a problem in terms of strength. Therefore, in the past, when a continuous room was required, for example, as shown in Figure 7, a beam H was attached to the ceiling between the small units U and U, and the wall panel was removed. Since this construction needs to be carried out on site, it has the disadvantage of prolonging the construction period, and furthermore, since the beam H hangs down from the ceiling surface, there is a disadvantage that there is a lack of openness between the continuations. There was also.

[Means for solving the problems] The present invention solves the problems in conventional unit buildings,
The purpose is to provide a wood-based 2-positive unit building that can have a space following the first floor, does not require the installation of beams during on-site construction, and can improve the factory production rate.

The configuration arranged in
The wooden connecting units on the first and second floors are stacked on top of each other, and the small wooden units that make up the wooden building unit groups on the first and second floors are individually stacked on each other, and on both edges of the floor panels of the connecting units on the second floor. It exists in a 2-positive wood unit building characterized by the provision of beams.

Wooden connection units and wooden small units that make up a group of wooden building units may include not only floor panels and wall panels, but also ceiling panels if they are one-story, or two-story. For example, a ceiling panel or even a roof portion may be provided integrally. If the wooden connecting units with integrated ceiling panels or roof parts and the wooden small units that make up the wooden building unit group are produced in factories, the number of assembly steps at the construction site will be reduced and the construction period will be shortened, but road transportation is It is desirable to comprehensively consider these merits and demerits and decide which one is preferable, since it may violate legal regulations or increase transportation costs.

Wood is mainly used as the material for constructing the wooden connection units and the wooden small units that make up the wooden building unit group, but metal fittings are used to connect the members, and some reinforcing bars are used for reinforcement. etc. may be used in combination.

The connections between the wooden connection unit and the wooden small units that make up the wooden building unit group, and the connections between each wooden small unit, are as follows:
Nails, bolts, nuts, and other conventional fasteners may be used.

In the present invention, in addition to having a total of two floors in which the building area of the first and second floors are the same as in the illustrated embodiment, the first floor has an entrance, or the first floor is a wooden building unit group. The number of small wood units may be greater than the small wood units that make up the group of wooden building units on the second floor, and the building area of the first floor may be larger than that of the second floor.
In any case, it is necessary for strength that the wooden connection units of the first and second floors overlap each other, and that the small wooden units forming the wooden building unit group of the first and second floors individually overlap.
