[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building unit used in a unit-type building, and more particularly to a building unit having a back space in a building.

[0002]

BACKGROUND ART Unit-type buildings constructed by combining a plurality of building units produced in a factory in advance at a construction site have been widely used in recent years because work on the construction site is greatly reduced. .

[0003] In such a unit-type building, in the case of forming a cabin back space that can be used for a living room or a storage room, a rectangular parallelepiped building unit 71 and a roof panel 75 are conventionally mounted as shown in FIG. A wedge-shaped triangular unit 72 having an inclined surface 72A to be placed is used, and the space in each of the units 71, 72 is used as the back of a cabin.

[0004]

However, in such a unit-type building, two types of units 71 and 72 having different shapes must be prepared in order to form a space behind the hut. There is a problem that the cost increases and the management of the units 71 and 72 is complicated.

[0005] Further, since the number of units 71 and 72 necessary for constructing the space behind the hut is large, installation and mounting work at the construction site increases, and the work on site becomes complicated, and the construction period becomes longer. was there.

Further, since the units 71 and 72 are assembled at a building site, these units 71 and 72 are combined.
In the case of forming a continuous space behind the hut, of the internal finishing work to paste the wall, ceiling, floor materials etc. of the space behind the hut,
At least the joint between the units 71 and 72 must be performed after the units 71 and 72 are installed. For this reason, there has been a problem that the on-site work becomes more complicated and the construction period is further lengthened.

Further, each of the triangular units 72 is also used to support a roof panel 75. At this time, the inclined surface 72A
The triangular units 72 must be accurately positioned and installed so that the roof ridges can be constructed by connecting the upper ends of the roof panels 75 mounted thereon, making the on-site work even more complicated. There was also a problem.

[0008] It is an object of the present invention to provide a building unit which has a low manufacturing cost and can reduce on-site work.

In the present invention, the building unit 20
Has a trapezoidal side shape. Since only the trapezoidal building unit 20 can form the same cabin back space as that obtained by combining the conventional rectangular parallelepiped building unit 71 and the triangular unit 72, two types of units having different shapes as in the related art are used. There is no need to prepare 71 and 72, and only one type of building unit 20 may be prepared for the space behind the hut. Therefore, the types of the building units 20 are reduced, the manufacturing cost can be reduced, and the management becomes easy.

When the roof 3 is configured by placing the roof panel 30 on the inclined surface, the roof panel 30 can be accurately placed simply by placing the roof panel 30 on the inclined surface. Since it can be eliminated, on-site work can be further reduced.

It is preferable that the upper surface and the lower surface formed of the panels 21 and 22 and the like are connected by columns 24. The upper surface portion can be supported only by the inclined surface portion. However, if the upper surface portion is supported by, for example, four pillars 24 standing on the bottom surface portion, the support strength of the upper surface portion is improved, and the building unit is supported. 20 can also be increased in rigidity.

Further, in the building unit 20, each of the inclined surfaces has the same length dimension along the inclined surface and the same inclination angle with respect to the bottom surface, and the side surface has a so-called isosceles trapezoidal shape. You may comprise so that it may become. In this case, since the building unit 20 is formed symmetrically, the strength balance of the building unit 20 can be improved, and when the roof is configured by attaching the roof panel 30 to each inclined surface portion, the ridge is sandwiched. Each roof slope can form the same roof.

Further, the inclined surface of the trapezoidal building unit 20 may be, for example, a bracket 2 for mounting a roof panel.
7, 28 and the like may be provided so that the roof panel 30 can be attached. In this case, after installing the trapezoidal building unit 20, by attaching the roof panel 30 to the inclined surface portion, the roof 3 having the space behind the hut can be easily formed, and the inclination angle and the like of each inclined surface portion can be easily formed. Since the accuracy is high, the ridge of the roof 3 can be easily formed by connecting the upper ends of the roof panel 30 to each other.

On the other hand, a roof surface member 41 may be pasted on the inclined surface of the trapezoidal building unit 20 in advance. In this case, the roof 3 having the space behind the hut can be configured only by installing the trapezoidal building unit 20, so that the on-site work can be further reduced. In addition, the upper side of the roof 3 may be configured by sticking a roof surface material on the upper surface of the trapezoidal building unit 20, or by mounting a triangular roof unit 42 having a triangular cross section on the upper surface. May be.
