Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention can efficiently connect a climbing beam and a climbing beam that extends orthogonally to one eave tip and improve the strength of the connection portion. Regarding the roof structure.

[Conventional technology]

Houses of prefabricated construction method, which is formed by arranging panel bodies such as roof panels and wall panels on a frame structure using steel frame materials, are often used, and in such houses, the ridgeline of the roof is mainly used. A parquet roof having a ridge and a pair of descending ridges extending from the end of the main ridge to the eave corners on both sides of the main ridge is sometimes used. Further, the roof set of such a roof is, for example, a purlin along the main ridge, a climbing beam along the descending ridge, a climbing beam crossing the eaves and connected to the climbing beam,
Furthermore, it is formed by using frame materials such as purlins that horizontally connect the climbing beams.

[Problems to be Solved by the Invention]

In order to improve the productivity and improve the strength and quality of a house construction having such a roof set, improvement in workability, strength and quality of the roof set construction is a prerequisite.

On the other hand, the climbing beam is usually a long body that connects the end of the main ridge and the corner of the eaves corner.

Conventionally, a climbing beam that extends at a right angle from the eaves is directly welded to the climbing beam, and there is no bundle material that supports the connection part. As a result, the load of two sloping roofs that intersect above the climbing beam is increased. However, it directly acted on the climbing beam and reduced the strength of the roof assembly.

The present invention, by arranging the bundle material in the vicinity of the connecting portion between the climbing beam and the climbing beam, it is possible to transmit the load acting on the climbing beam downward,
The purpose is to provide a roof structure that improves the strength of the roof structure and helps stabilize the quality.

[Means for Solving the Problems]

The present invention provides a climbing beam extending from the end of the main ridge along the descending ridge that extends to the eaves corners on both sides of the main ridge, and the lower end extends to the eaves and is orthogonal to the eaves. In the roof construction structure, which connects the upper ends of the climbing beam, and arranges a bundle member connecting the lower surface of the climbing beam and a horizontal beam member that is below the climbing and is orthogonal to the eaves in the vicinity of the connecting portion. is there.

[Action]

By providing a bundle member that connects the climbing member and the beam members located below it in the vicinity of the connection portion between the climbing beam and the climbing beam, the load acting on the sloping roof extending on both sides of the climbing beam can be reduced. Can be transmitted to the beam through the, and the strength of the roof assembly is improved.
