It can be easily rained off and can be designed to meet design needs. Further, even in the case of a vaulted roof with a gentle arch, the height of the attic space or the ceiling height can be increased by the vertical rising member of the vault beam. In that case, when the vault roof continues to the outer wall of the building, the rising beam part of the vault beam is
It will be the part that is joined to the upper end of the pillar of the outer wall. Further, even when the vault roof continues to a roof portion different from the flat roof, the waist wall portion can be formed by the rising material, so that it can be easily accommodated with the adjacent roof portion. Moreover, since this vault beam has the rising member at the lower end, it is not necessary to construct a bundle separately from this vault beam, and the workability is excellent.

In the above structure, each of the vault beams may be composed of a pair of vault beam members arranged on both sides of the ridge portion, and both vault beam members may be coupled to each other in the ridge portion by a fastening tool. In this configuration, since the vault beam is composed of a pair of vault beam materials, it can be transported in the state of one vault beam material at a time, and it is not bulky to transport the vault beam to the site. It can be joined simply by fastening the vaulted beam material of in the ridge.

In the present invention, the vault beam is
It may be a structure of a cottage for the vault roof portion adjacent to the flat roof portion. In this case, on the flat roof part side of the rising member of the vault beam,
A waist wall panel may be attached, and a vault roof panel may be attached to an arched portion of the vault beam that continues from the rising member. In this configuration, since the rising member of the vault beam is used for mounting the waist wall panel, the waist wall panel can be installed in the joint between the vault roof part and the flat roof part well, and the waist wall panel Good workability.

In the vault beam made of steel according to the present invention, the rising member is connected to the lower end of the arched beam extending from the ridge to the vicinity of the eaves. According to this configuration,
By joining a pair of the vault beam members at the ridge portion to form a vault beam, and by joining the lateral beam members with the rising members on both sides thereof, it is possible to construct a roof roof cottage with good workability. Moreover, the constructed vault roof is
The height of the attic space is high and it fits well in the surrounding area.
