Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a roof panel mounting structure that allows roof panels to be mounted safely and efficiently, and that greatly reduces the effort required for roof construction.

[Background technology]

Conventionally, in order to attach a roof panel to a roof beam for forming a flowing roof, as shown in Fig. 5, roof panel A is suspended by a crane, etc., and then temporarily placed on roof beam B slightly above the installation position. At the same time, the roof panel A is positioned by sliding it down to the installation position, and the roof panel A thus positioned is bolted to the rafter member D by the panel fasteners C driven into the roof beam B. It was fixed by being

However, when positioning is done in this way, conventionally the roof panel A does not have a structure that engages with the roof beam B, and the work is carried out in an unstable state suspended from a crane or the like. In addition to requiring a great deal of effort, the accuracy was also poor. Further, the roof panel A must be suspended by a crane or the like until it is attached to the panel fastener C, and therefore there is a risk of the roof panel falling during the entire construction work.

On the other hand, as shown in FIG.
It is also conceivable to temporarily place the roof panel A by attaching an L-shaped panel holder F that can be fitted into the roof panel A. However, in this case, when adjusting the position by sliding the roof panel A, the bolt G for attaching the panel holder F may come into contact with the rafter member D, making it impossible to perform the position adjustment reliably. There are also problems such as the roof panel A cannot be attached when located below the rafter member D.

[Purpose of invention]

In the present invention, a panel bracket is bolted to a roof beam, which includes an upright piece that fits into a notch in a rafter member and an overhanging piece that protrudes indoors and can fit into a panel fastener that is fixed to the rafter member. The object of the present invention is to provide a roof panel mounting structure that allows roof panels to be mounted safely and accurately and that solves the above-mentioned problems.
