Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method of fastening a plurality of different box-shaped roof units integrating a roof panel and a hut frame supporting the roof panel with adhesive bolts. More particularly, the present invention relates to a construction roof unit having a vertex of a corner ridge of a prefabricated ridge roof.

"Conventional technology" In prefabricated single-family homes, planning-type prefabricated homes, such as "free style", are supplied in place of already standardized homes. Various types have been developed to meet diverse needs.In particular, the roof shape is an important factor in determining the style of a house. Various types of roofs, such as roofs, ridge roofs, and square roofs, are provided.

By the way, such a planning-type house can strongly enhance the individuality of the house, but it has disadvantages in terms of construction period and cost due to an increase in dependence on on-site construction and an increase in the number of parts. Yes, especially the roof
Unlike floors, walls, etc., whether using trusses, using panels, or using wires such as bundles and rafters, it takes time to set up huts at the site, especially for roofs in wings. However, there is a problem that various types of parts must be prepared in consideration of various types of component configurations corresponding to the roof shape.

FIGS. 21 to 24 show an example of the construction of such a detached prefabricated house. In this conventional example, as shown in FIG. 21, a unitized floor is constructed on a concrete foundation 1 constructed on site. Panel 2 is laid, and first and second floor wall panels 3 are assembled thereon as shown in FIG. 22 and FIG. In this manner, the steps of assembling the roof panel 4 and constructing a building are performed.

In addition, each said panel (floor panel 2, wall panel 3, etc.)
The floor panel 2 is integrated with an adhesive and a screw nail or the like, and the floor panel 2 is laid through a pedestal on an adjustment mortar adjusted on the upper surface of a foundation (a cloth foundation in the illustrated example) 1, and the first floor portion is The wall panel 3 is integrated with the foundation by dropping a hole at the lower end of the wall panel into an anchor bolt protruding from the upper surface of the concrete foundation and tightening the bolt.

On the other hand, as for the assembly of the roof, basically, all types of roofs are similarly assembled in order at beams, huts, roofs and high places, for example, as shown in FIGS. 23 and 24 and the like. With such a gabled roof, after forming a hut by, for example, bridging the beam members 5 on the second-floor wall panel 3, a roof panel 4 is laid thereon, and the roof panel 4 is formed as a hut. Means of integration are taken.

"Problems to be solved by the invention" However, the conventional roof assembly involves the steps of building beams, sheds, and roof panels in order,
Poor workability on site, especially for buildings with a roof-like shape, which requires more time and effort than for a flat roof, and also requires more skilled workers and is more costly. was there. In particular, the work of assembling the roof, of course, is performed at a high place in the building, so the danger is high, and because it takes time to assemble, the building is exposed to rain during assembly, There was a problem that it was difficult to ensure stable quality. Therefore,
The present inventor has conducted intensive studies to solve these problems, and as a result, if the roof is configured by a roof unit integrating a roof panel and a hut assembly, and if these roof units are combined and constructed, On-site work becomes easier, and the construction period can be shortened and quality can be improved.
