DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art Conventionally, the space behind a shed of a unit-type building is formed by installing triangular prism-shaped triangular units on both sides of a box-shaped building unit arranged at the center of the top floor, and the hypotenuse of the triangular unit. (Japanese Patent Laid-Open No. 11-107378).

[0003]

However, if a space behind a hut is formed by using such a triangular unit, pillars and the like of the triangular unit and a building unit are installed close to each other, and the structure of the hut behind the triangular structure becomes triangular. Since the truss structure is formed by the pillars and beams of the unit, the rigidity of the back of the hut is greater than that of the lower floor where no truss is formed, and there is a problem that the rigidity balance of the entire unit building is poor. .

[0004] It is an object of the present invention to provide a unit-type building capable of improving the rigidity balance between the back of a hut and the lower floor.

[0005]

According to the unit type building of the present invention, an upper edge 50 of a box-shaped upper-floor building unit 5 arranged on the upper floor will be described with reference to the symbols in the embodiments described later.
And the roof panel 71 is provided so as to straddle the upper edge 40 of the box-shaped lower-floor building unit 4B located parallel to and outside of the upper edge, so that the roof panel and the lower-floor building A hut back space 8 surrounded by the ceiling side of the unit is formed.

According to this invention, the roof panel is provided so as to straddle the upper edge of the upper floor building unit and the upper edge of the lower floor building unit, thereby forming the back space of the unit type building. The number of pillars, beams, etc. in the back of the hut is reduced compared to the case of forming the back of the hut using a triangular unit as in the past, and the rigidity balance between the back of the hut and the lower floor of the unit type building is improved. Get better.

The lower-floor building unit comprises a rectangular frame-shaped shed panel 42 having an upper surface at the same height level as the floor of the upper-floor building unit. It is desirable that the eaves side of the roof panel is joined. In such a case, since the height level of the floor of the upper-floor building unit and the height of the hut panel are the same, the height level of the floor in the back space of the hut formed in the unit-type building can be easily adjusted. .

Further, the roof panel includes a support member 72.
Preferably, the support member has a horizontal fixed surface 72A fixed to each upper edge and an inclined support surface 72B for supporting the roof panel. In such a case, since the roof panel is attached to the upper edge via the support member, the roof panel can be easily and firmly attached to the upper edge.

The roof panel includes two panel bodies 911 arranged in a straddling direction (inclination direction), and these panel bodies are provided on a support surface of a support member on the upper floor building unit side. It may be connected above. In such a case, since the roof panel is formed by arranging two panel bodies in the straddling direction, for example, when forming a large roof, each panel body is transported by a truck or the like and connected on site. It is not necessary to carry one large roof panel, and transportation becomes easy. Further, since the panel body has good handleability, workability when forming a roof on the top floor is also improved. Furthermore, since these panel bodies are connected on the support surface of the support member, the strength at the connection portion of the panel body is reliably ensured, and the roof surface strength equivalent to that of the integral roof panel is maintained.

On the other hand, the roof panel may be an integral body that is continuous in the straddling direction. In such a case, since the roof panel is an integral body that is continuous in the straddling direction, no connecting portion is formed along the girder direction of the roof surface, and the strength of the roof surface is more reliably maintained.

Further, the lower-floor building units are respectively installed on both sides of the upper-floor building unit, and the roof panels are laid across the upper-floor building units and the respective lower-floor building units. Is also good. In such a case, a two-sided roof that is inclined on both sides of the upper-floor building unit is easily formed.
