Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is capable of forming a strong roof structure with a roof pillar having an eaves side beam piece that is inclined at the upper end of a pillar piece, and increases the efficiency of roof construction. Regarding the roof frame structure that can also fulfill.

[Conventional technology]

Conventionally, work on the roof has been performed by sequentially lifting and building a purlin, a nose purlin, etc. along with a purlin by using a bundle material or the like on a beam at the upper end of the main body of the house.

However, in the construction method of sequentially lifting the members in this way, the number of times each member is lifted increases, the time for the crane work becomes long, and the time for the work on the upper wing is extended, so that the work efficiency decreases and the work cost increases. Further, this also increases the time required for work at heights, and the work safety is poor.

Therefore, the inventor of the present invention measures the efficiency of the upper ridge construction by suspending an integral roof frame structure in which a plurality of roof beam members are connected by a connecting beam, for example, by suspending it with a crane or the like, and erected between the beams of the main body of the house. We have devised a roof construction method that can shorten crane work time, reduce costs, and improve work safety.

[Problems to be Solved by the Invention]

However, although such a roof frame structure is assembled on the ground, it is necessary to streamline such an assembly work on the ground and to strengthen the strength of the roof frame structure.

According to the present invention, by fixing the eaves-side beam piece to the upper end of the support-piece, the strength of the intersection between the support-piece and the eaves-side beam piece, which has a large bending load, is improved and the efficiency of the assembly work is measured. The purpose is to provide a Uru roof frame structure.
