DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building unit and can be used for a building such as a unit house constructed by a unit construction method.

[0002]

2. Description of the Related Art Conventionally, as a prefabricated building, a unit building constructed by assembling a plurality of box-shaped building units previously manufactured in a factory at a building site has been used. The building unit that constitutes such a unit building has a hexahedral frame in which the upper and lower ends of each pillar arranged at four corners are connected by beams.

[0003]

In such a building unit, since a flat outer wall material made of lightweight cellular concrete or the like is simply attached to the side surface of a hexahedral frame, irregularities are formed on the outer wall portion. Not done. For this reason, buildings built with these building units can be configured in various layouts etc. by combining each unit, but on the other hand, it becomes a monotonous combination of multiple hexahedrons only, and the outer wall part has little change and a design There is a problem that there are few variations.

Further, in order to increase the rigidity of the building unit, reinforcing members such as braces which are diagonally laid on the side surfaces of the frame of the building unit and studs which are erected at intermediate portions of the respective side surfaces of the frame are used. ing. However, since these reinforcing members are arranged on almost the same plane as the outer wall portion, if an outer wall material having a concave portion is installed in order to provide unevenness on the outer wall portion of the building unit, the concave portion of the outer wall material and the reinforcing member will be separated. It may interfere. For this reason, there is a problem that large irregularities cannot be provided on the outer wall portion of the building unit.

An object of the present invention is to provide a building unit that can increase the variation in the appearance of the unit building and increase the rigidity.

[0006]

According to the present invention, there is provided a frame formed in a rectangular parallelepiped shape by connecting the upper and lower ends of four corner columns with beams.
Including a portion that is arranged to be inclined with respect to the longitudinal direction of the beam and that is vertically erected inside the frame.
It possesses a planar structure surface portion, at least in the structure surface portion
It is characterized in that part of the outer wall faces the outside .

Here, as the structural surface portion, a wall material such as a reinforced concrete panel which gives strength to the wall material itself, and
A wall material or the like combining a frame-shaped frame formed in a square frame shape and a relatively low-strength surface material such as lightweight cellular concrete attached to the frame-shaped frame can be adopted.

The above-mentioned structural surface preferably connects the upper and lower surfaces of the building unit. The structural surface is provided with windows, doorways, and openings for communicating with passages and living rooms. Is also good.

[0009]

According to the present invention, a building unit in which corners and outer walls are recessed toward the indoor side can be formed by using part or all of the surface of the oblique structural surface in the building unit as the outer wall surface. Becomes When a unit building is constructed with such a building unit having a dent, irregularities are formed on the outer wall portion of the unit building, and the appearance of the unit building is improved.

Further, changing put the installation position of the building unit of conventional building unit and the present invention, for example, up and down also
By reversing the left and right arrangement, it is possible to change the appearance of the unit building. Furthermore, by preparing many types of building units having different crossing angles and installation positions of the structural surface portions, it is possible to give variations to the uneven shape of the outer wall portion. These greatly increase the design variations of the unit building.

Further, since the structural surface portion installed on the building unit can mutually connect beams facing each other or orthogonal to each other among beams constituting the frame of the building unit, Can be reinforced. In particular, by arranging the structural surface portion obliquely, the rigidity of the building unit against falling down is improved. For this reason,
The rigidity of the unit building constructed with this building unit is increased, thereby achieving the above object.
