2. Description of the Related Art In recent years, in order to meet the demand for mass production of houses and the like and shortening of the construction period, constituent members of buildings are divided into units, and each unit is produced at a factory and assembled on site. . This style has many advantages, such as enabling mass production, easy transportation, and easy on-site assembly, and matches modern demands.

[0003]

However, in a building such as a house, components such as pillars, walls, floors, and ceilings can be divided into units to be factory-produced and transported, but the roof has an overall shape. Are large and difficult to transport by vehicle. For this reason, most of the roof construction must be performed on site, which has been a major bottleneck in mass production of such buildings and shortening the construction period.

As one means for solving this problem, the present inventor has developed a roof structure in which the left and right roof plates of a gabled roof having a mountain-shaped top are split into two parts so as to be able to expand and contract in the axial direction. A patent application has been filed as Japanese Patent Application No. 9-150184. This can be transported with the roof plate of the gable roof contracted, stretched at the construction site and finished to the original gable roof shape, but between the top (ridge) of the left and right roof plates and the eaves However, there is a problem that it is difficult to obtain a strength that conforms to the building standards because it is divided into two.

Accordingly, a first object of the present invention is to provide a roof having a roof structure having a strength conforming to the building standards, in which a roof is formed only by combining the divided units capable of factory production and vehicle transportation at a building site. It is to provide a construction method.

The structural members 1a and 1b are assembled together with the roof structure 1 facing each other.

The roof structure 1 of the present invention according to the embodiment of FIG.
Is composed of a pair of left and right roof components 1a and 1b each having a structure in which the roof is vertically divided into two along the ridge direction.

As shown in FIG. 1, each of the roof components 1a and 1b has an inclined roof plate 2 on one side of a roof structure 1, and a plurality of columns 3 extending downward from the upper end of the inclined roof plate 2. A beam 4 connecting the columns 3 and a plurality of beams 5 connecting the columns 3 or the beams 4 and the roof plate 2 are provided.
The girder member 4 and the beam member 5 are assembled to an integral frame unit that can be transported by a vehicle or the like, and constitute one side of the roof structure. Preferably, these columns 3, girder members 4, and beam members 5 that support the roof plate 2 are assembled in a structure that can provide the same strength as conventional on-site construction.

As shown in FIG. 1, a reinforcing member 6 may be suspended between the inclined roof plate 2, the support 3, the beam 4, and the beam 5.

Although the embodiment shown in the drawings illustrates a case in which the roof components 1a and 1b have the same shape on the left and right, the present invention is not limited to this structure, and the shapes on the left and right are different depending on the desired roof shape. In some cases.

According to the present invention, the roof structural members 1a and 1b of the divided structure are manufactured in advance in a factory or the like other than the building construction site of the house as described above, transported to the building site, and combined as shown in FIG. It is to let. Therefore, each roof component 1
a and 1b are formed in a size that can be carried by vehicles such as trucks and trailers.
