Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a joint structure for the valley corners of roof panels in prefabricated houses.

[Conventional technology]

For example, in the case of the hipped prefabricated house shown in Figure 3, the valley corner A of roof panels 1 and 2 is conventionally joined by attaching two roof panels to each other. Arrange the two roof panels in a valley shape at the required slope by placing them in contact with each other, and then nail the two valley corner adjustment materials, or glue the two valley corner adjustment materials together to connect the two roof panels to each other. It is joined.

[Invention or problem to be solved]

In the case of the above-mentioned conventional nailing connection, a dowel nail on the sloped roof panel must be driven diagonally from one valley corner adjustment member to the other valley corner adjustment member, which requires advanced technology. However, if the nails are not driven correctly, the required joint strength cannot be achieved.

In addition, when bonding with adhesives, rain (moisture) and hot water temperature affect the adhesive strength, and it is necessary to avoid large sway due to wind etc. until the bonding is completed, so the specified bonding strength can be maintained regardless of weather conditions. It is not easy to obtain.

For this reason, nails and adhesives are often used together, but it is time-consuming and has problems in terms of work efficiency, and the problems of both methods still remain and have not been resolved, so it is difficult to strengthen the bond. The reliability of the system is also not sufficient.

The present invention does not require advanced technology or skill, can be efficiently constructed without being affected by temperature or rain, and is strong and reliable. The purpose of this invention is to provide a joint structure at the valley corner of the roof and S+ flannel.

[Means to solve the problem]

In order to achieve the above object, the first invention provides two roof panels each having a valley corner adjustment material provided on the outer surface of the core material, by making the valley corner adjustment materials face each other and adjusting the required slope. A connecting tool with tongue pieces connected on both sides of the lower end of the main piece is inserted into the valley corner adjustment material of both roof panels in a valley shape, and the main piece is inserted between both valley corner adjustment materials. At the same time, both tongue pieces are individually applied to the bottom surfaces of both valley and corner adjustment members, and the main pieces and tongue pieces are nailed to the valley and corner adjustment members.

The second invention is to arrange two roof panels provided on the outer surface of the valley corner adjustment material or core material in a valley shape at a desired slope with the valley corner adjustment materials facing each other. Then, insert a connecting tool with tongue pieces connected to both sides of the lower end of the main piece into the valley corner adjustment material of both roof panels, and insert the main piece between both the valley corner adjustment members, and attach both tongue pieces. The main pieces are attached to the core material of the roof panel individually, and the main pieces are nailed to the valley corner adjustment material, and the tongue pieces are nailed to the core material of the roof panel.

[Effect]

The valley corner adjustment materials of the two roof panels are connected to each other via a joining tool, and there is no need to drive nails diagonally from one valley corner adjustment material to the other valley corner adjustment material. All you need to do is nail the corner adjustment material, nail the main piece of the connector to the valley corner adjustment material of the roof panel, and nail the tongue piece to the valley corner adjustment material or core material of the roof panel, or both.
No advanced technology or skill required. Further, since the main piece of the connector and one of the tongue pieces can be nailed to the roof panel in a factory or on the ground with good footing, the work can be done efficiently. Furthermore, since nails can be driven vertically into the valley corner adjustment material, the strength of the nails can be fully utilized, and strong and reliable joint strength can be obtained.
