Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention makes it possible to standardize panel bodies, which are classified by strength, by additionally attaching reinforcing materials, thereby reducing the number of types. Regarding Uru roof panels.

[Conventional technology]

In recent years, roof panels in which roofing boards or the like are attached to a framework have been widely used to improve roof construction efficiency and shorten construction time.

On the other hand, in the case of houses, the load acting on the roof varies depending on the location conditions such as heavy snowfall areas or light snowfall areas, and structural conditions such as the support pitch of the frame structure. It is also necessary to use panels that have strength according to the load they bear.

[Problems to be Solved by the Invention] Conventionally, however, the strength of roof panels has been changed appropriately by changing the number of frame materials used, pitch spacing, and cross-sectional shape, etc. This led to an increase in production efficiency and was a major cause of declines in production efficiency, management efficiency, etc.

Furthermore, if roof panels with high strength are commonly used even in low-load cases, and the number of types is reduced, there is a problem that the quality will be excessive and the cost will increase.

The present invention is based on forming an attachment part on the upper frame material to which a reinforcing material can be attached, which makes it possible to provide a single panel with various strengths, thereby reducing the number of types of panels without resulting in excessive quality. The aim is to provide roof panels that can measure

[Means to solve the problem]

In order to achieve the above object, the roof panel of the present invention is supported at both ends by the house frame structure, and has both ends of the upper frame member located at the ridge of the roof and the lower frame member located at the eaves side. A field board material is attached to one side of the frame connected by the frame material, and the upper frame material has an attachment part formed in advance on the lower surface to which a reinforcing material of approximately the same length as the frame material is attached. .

[Effect]

In a roof panel constructed in this way, reinforcing material can be additionally fixed to the upper frame material located at the ridge where the maximum load is applied, so the load-carrying capacity can be efficiently changed, and one type of roof panel can be used. Roof panels can handle various loads that vary depending on location conditions, etc.

Therefore, it is now possible to standardize roof panels of various qualities, which were previously caused by differences in the load they bear.
It is possible to improve production efficiency, management efficiency, and reduce costs.
