[Problems to be Solved by the Invention] When constructing a hipped roof with a steel truss and a roof panel, it is difficult to realize a roof having a complicated planar shape, and the number of types of steel truss and roof panel parts is enormous. There is a problem that becomes. In particular, there is a problem that the size of the steel frame truss becomes large according to the size of the building, making it difficult to carry and carry in, resulting in poor workability.

In addition, if it is attempted to construct a hipped roof without using a steel truss, there is a problem that it becomes difficult to fix a plurality of roof panels concentrated on the top.

An object of the present invention is to provide a structure for forming a hipped roof without using a steel truss, and a collective bracket used for realizing this structure.

[0006]

Means for Solving the Problems In order to solve the above-mentioned problems, a hipped roof structure according to the present invention is a hipped roof structure constructed by using roof panels, which is concentrated on the top of the hipped roof. The upper and lower surfaces of the plurality of roof panels are supported and fixed by a collective bracket attached to the roof frame.

In the above-mentioned hipped roof structure, by disposing the collective bracket on the top of the hipped roof, it is possible to attach and support the lower surfaces on the upper ends of the plurality of roof panels concentrated on the top to the collective bracket. Therefore, the ridged roof can be configured by using the ridge beams and the purlin beams supported by the bundle without using the steel truss.

Further, the assembly bracket according to the present invention comprises a support portion for commonly supporting the upper and lower surface sides of a plurality of roof panels concentrated on the top of the ridge roof, and a connecting portion for connecting to the roof frame. It is something.

Since the above-mentioned assembly bracket has the supporting portion and the connecting portion, it can be connected to the roof frame (for example, the main beam) corresponding to the top of the ridge roof through the connecting portion. Then, the support portion can support the lower surfaces on the upper end side of the plurality of roof panels concentrated on the top portion.
