More particularly, the present invention relates to a roof unit that constitutes four corners of an assembled ridge roof.

"Conventional technology" In prefabricated single-family homes, for example, instead of standardized and standardized homes, for example, planned prefabricated homes called "free style" are supplied, and exterior and interior design 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.

(B) Further, according to the construction roof unit, since the four corners of the roof can be formed only by placing the girder material on the outer wall panel, the assembling work at the site becomes easy, and the roof units are combined. Since the part is constituted by a triangular panel, it is possible to easily act as a means for fastening the mating surfaces of the triangular panel to each other with an adhesive bolt.
Since the roof unit as a whole constitutes the four corners of the wing roof, the connecting operation of the roof units does not have to be performed on the roof, and the safety thereof can be improved.

(C) Further, as described above, it is possible to provide an effective and appropriate roof unit for forming a prefabricated ridge roof.
