The roof of a unit building that is formed by

[0002]

BACKGROUND ART Conventionally, a unit-type building constructed by combining a plurality of building units manufactured in a factory in advance at a construction site has been used. According to this unit-type building, the work at the construction site is significantly reduced. As a result, the construction work can be completed in a short period of time. In such a unit-type building, a roof formed by a plurality of roof panels formed in a plane shape can be adopted, and a conventional example of such a roof includes a structure disclosed in Japanese Patent Laid-Open No. 7-113283. . In the roof structure shown in this publication, a plurality of bundles having a length reaching the vicinity of the top of the roof are erected on the upper surface of a building body in which a plurality of box-shaped building units are combined, and roof panels are formed by these bundles. It is supposed to support. Then, in order to improve the rigidity of the bundles erected on the upper surface of the building body, braces are bridged between these bundles.

[0003]

However, in the above-mentioned roof structure, since the bundle standing upright on the main body of the building is long, the work of standing up the bundle is complicated, and the work of bridging the brace between the bundles is required. However, the roof construction becomes complicated and it takes time to construct the roof on the construction site. Therefore, there is a demand for a roof structure that further reduces the construction work on the construction site.

An object of the present invention is to provide a roof of a unit-type building which can further reduce construction work at a construction site.

[0005]

The present invention is provided in a unit type building in which a plurality of box-shaped building units are combined, and a plurality of planar roof panels are inclined on both sides of the ridge. A roof of a unit-type building formed by arranging, a trapezoidal unit formed in a box shape including an inclined surface in the upper part is arranged on the upper part of the unit-type building, and the roof panel is It is a roof of a unit-type building characterized by being installed along an inclined surface. In the above, it is preferable that the ridge-side edges of the plurality of roof panels are connected to each other by a connecting member, and a portion near the eaves leading edge is joined to the trapezoidal unit via a bracket. Further, as the trapezoidal unit, one having the inclined surface provided along one side of the upper surface can be adopted, and when such a trapezoidal unit is adopted, the inclined surface is directed to the outdoor side, and It is desirable that a plurality of units are arranged at positions sandwiching an ordinary building unit arranged in the upper center of the unit type building. Further, as the trapezoidal unit,
It is possible to adopt a structure in which the inclined surfaces are provided along two opposite sides of the upper surface, and by adopting such a trapezoidal unit, a pair of the roof panels that are inclined and arranged on both sides of the ridge can be attached. In addition, a plurality of trapezoidal units are arranged along the periphery of the unit type building, and one of these trapezoidal units arranged at a corner of the unit type building is arranged on each of two adjacent sides of the upper surface. If the inclined surface is provided along the inclined surface and the remaining trapezoidal unit is provided with the inclined surface along one side of the upper surface, a ridge-type roof can be formed.

According to the present invention as described above, since the roof panel is attached along the inclined surface of the trapezoidal unit, the roof having the inclined roof surface is formed and the roof is formed even if there is no long bundle. The panel can be joined to the frame of a box-shaped trapezoidal unit. Here, by joining the roof panel to the frame of the trapezoidal unit, the roof has sufficient rigidity. Therefore, it is not necessary to use multiple bundles with a height reaching the top of the roof and braces bridged between these bundles to install the roof panel, and it is necessary to perform complicated bundle erection work and brace construction work. Is unnecessary, and the construction work at the construction site is reduced, thereby achieving the above-mentioned object.
