[0006]

However, in the above-mentioned conventional assembled roof, since the beam receiving portion 9 is directly attached to the girder 2 or the corner girder 2a, the joint portion between the girders is oblique. However, the ends of the girders cannot be cut off, so that joints and spacers are used without directly connecting the girders. Therefore, the width of the opening portions X1 and X2 on the inner circumferential side of the corner is increased, and the central angle of the sector formed by the beams 3 and 3 is limited to about 30 degrees or more. That is, the division angle of the corner portion becomes large. There is a problem that the degree of freedom in setting the corner angle is low and the corner is not smoothly curved. Also, depending on the angle, a considerable number of joints, spacers and the like must be used as shown in the figure, and there is a problem that assembly is troublesome. Furthermore, since many joints and spacers are used, there is also a problem that appearance may be deteriorated due to processing of a gap between them.

[0007] The present invention has been made in view of such a conventional problem. An assembled roof in which beams can be directly connected to each other at a corner so as not to hinder the mounting of a beam, and the angle at which the corner is divided can be reduced. The purpose is to provide.

[0008]

[Effects of the Invention] As described above, the assembled roof according to the present invention cuts the girder extending to the upper end of the column in accordance with the bending of the corner portion and directly butt the bracket to the bracket receiver attached to the upper surface of the butt portion. The bracket 23 attached to both ends of the beam 23 is attached and the beam 23 is stretched,
Panels are attached to each of the openings surrounded by beams, purlins, and panel receiving members, which eliminates the need for joints and spacers to connect the girder, reducing the angle at which the corners are divided, and allowing the corners to bend. There is an effect that the degree can be set with a high degree of freedom. In addition, since the bend of the corner can be freely set, there is an effect that the number of divisions can be increased to form an assembled roof having a smoothly bend corner. Further, since the girders are directly connected to each other, there is also an effect that the appearance is excellent.
