DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to roof panels and unit buildings.

[0002]

2. Description of the Related Art Conventionally, when constructing a roof of a unit building, a roof truss as described in Japanese Patent Application Laid-Open No. 50-2315 is produced in a factory, and this roof truss is transported to a building site to construct a building unit. The roof truss will be equipped with a ceiling and a roof finish in order.

[0003] Also, in a unit building,
As described in Japanese Patent No. 06641, when a plurality of building units are separated and a roof is provided above the separated building units, a roof support beam is bridged between the separated building units, and A roof truss as described above is installed on the beam, and a ceiling and a roof finish are sequentially mounted on the roof truss.

[0004]

However, the prior art has the following problems. In constructing the roof of the unit building, the roof truss,
The ceiling and roof finish are transported to the construction site as separate parts,
Since these are assembled at the construction site, the number of parts is large and the handling is poor, the on-site work takes a lot of time, the roof construction period until the completion of the rain is long, and the roof construction cost is disadvantageous. Becomes

[0005] When a roof is provided above the separated building units, a roof support beam is bridged between the separated building units, and then a roof truss is installed on the roof support beam. It is necessary to attach the ceiling and roof finish to the roof truss one after another, which requires many on-site work steps and poor on-site workability.

An object of the present invention is to reduce the roof construction cost while shortening the roof construction period until the completion of the rain closing when constructing the roof of the unit building.

Another object of the present invention is to reduce the number of on-site work steps and improve the on-site workability when constructing a roof between separate building units.
