Description

[Detailed description of the invention] Industrial application field This invention is applicable to sunrooms, greenhouses, living rooms, etc. that are connected to the exterior walls of houses, as well as prefabricated greenhouses, children's rooms, greenhouses, etc. that are installed independently of houses. This invention relates to a connection device between a rafter and a front wall vertical beam in prefabricated buildings such as the above.

Prior Art and its Problems In the assembled building as described above, the roof is formed by fitting roof sheets into gaps arranged at predetermined intervals in the left-right direction, and slopes downward toward the front. are doing. The front wall is formed by fitting a front wall plate between front wall vertical bars arranged at predetermined intervals in the left-right direction at positions corresponding to the barrels. Rainwater, etc. that enters through the seal between the rafter and the roof board flows through the gutter provided on the rafter, enters the gutter provided on the vertical beam of the front wall from its front end, and is discharged from its lower end. It's becoming like that. However, conventionally, the front end and the top end of the vertical bar are cut diagonally, and the two are butted against each other, so that the rafters and front wall vertical bars are cut in such a way that they straddle the two on either the left or right side. Connecting plates were placed and these were connected by fixing them with bolts and nuts. Therefore, a gap is likely to be formed at the joint between the rafter and the vertical beam of the front wall due to misalignment, and there is a problem in that rainwater or the like flowing through the gutter of the rafter enters the assembled building through this gap.

The purpose of this invention is to provide a connection device between a rafter and a front wall vertical beam in a prefabricated building, which solves the above-mentioned problems.

In such a configuration, if rainwater enters from the seal between the roof board 13 and the rafter 40,
This rainwater flows forward in the gutter portion 50 of the rafter 40, enters the water guide path 93 of the connector 80 from its front end, passes through this, and enters the gutter portion 70 of the front wall vertical beam 60. Then, it flows down the inside of the gutter section 70 and is discharged from the lower end thereof.

In the above embodiment, the two barrel members 41 constituting the barrel 40, the tenons 85 of the two connector components 81 constituting the connector 80,
86, and the two vertical frame members 61 forming the front wall vertical frame 60 are bolted together with bolts 94, 95,
Although it is fixed with nuts 96 and 97, it is not necessary to fix these. Further, in the above embodiment, the main body 84 of the connector component 81 is made of synthetic resin, and the tenons 85, 80 are made of metal, but both may be integrally molded by aluminum die casting. Furthermore, in the above embodiment,
Although the connector 80 is composed of two connector components 81, it is also possible to make an integral piece with the shape of both connector components 81 and use this as a connector. Furthermore, the rafter 40 is made up of two barrel constituent members 41, and the front wall vertical bar 60 is made of two vertical bar constituent members 61, but the present invention is not limited to this. Each may be composed of one member. In addition, in the above embodiment, the rafter 40 and the front wall vertical beam 6
0 is made of extruded aluminum, but is not limited to this. Furthermore, in the above example,
An opening may be formed in the front wall 20, and a sliding door, a window, etc. may be provided in this opening.

Effects of the invention According to the connecting device of this invention, the two tenons of the connecting tool are inserted into the mortise of the rafter and the mortise of the vertical beam of the front wall, and the front end surface of the rafter is inserted into the mortise of the connecting tool. It is possible to connect the rafters and the front wall vertical beam by making them come into contact with the abutting surface and by bringing the top end surface of the front wall vertical beam into contact with the vertical beam abutting surface, which makes the work extremely easy. be. Furthermore, according to the connecting device of this invention, water in the gutter of the rafter flows forward, enters the water guide path of the connecting device from its front end, passes through here, and enters the gutter of the vertical frame on the front wall. It enters the interior and flows down the gutter. Therefore, water such as rainwater that has entered through the seal between the roof board and the rafters is quickly discharged without entering into the assembled building. Moreover, since the rain cover member provided on the connector covers the joint between the main body of the connector and the rafter and front wall vertical frame, even if there is a gap in this joint, the assembly can be carried out from this joint. Prevents water from entering the building.
