Description

[Detailed explanation of the invention] This invention is a support structure for a rafter installed at the outermost end in the gable side among the rafters constructed in the side eave part that protrudes in the gable side direction from the gable side support. It is related to.

Generally, the installation of rafters at the side eaves is done as shown in Figure 1: the gable side beam 9 and the girder side beam 1.
A cantilever beam 2' is made to protrude from the front upper part of the support column 10 on which the cantilever beam 2' is attached, and fixed with bolts 8.
As shown in Figures 2 and 3, the rafters 7
was mounted on an inclined shelf. However, since the rafters 7 are mounted on the cantilever beams 2', the distance between the top surface of the rafters 7 and the lower end of the cantilever beams 2', that is, the gable height H' increases, which causes a problem of deteriorating the appearance. Was. In addition, since the rafters 7 are fixed to the cantilever beam 2' by simply placing the rafters 7 on the cantilever beam 2', the strength of the rafters 7 against the blow-up load is weak, and the installation of the rafters 7 is unstable. There were also problems.
In order to solve this problem, the cantilever beam 2' is fixed with bolts on the column side beam 1 as shown in FIG. 4, and the rafter mounting bracket 13 as shown in FIG. As shown in FIG. It is conceivable to strengthen the connection strength between the upper and lower rafters 14 and 15. However, with such a means, the support strength of the outermost rafters 14 and 15 in the gable direction becomes weak, and conventionally, as shown in FIG. 11 had to be provided. Fourth
In the figure, 27 is a nose plate.

The present invention has been developed in view of these conventional drawbacks, and its purpose is to provide a rafter bracket at the outermost end in the gable direction by rationally configuring the rafter bracket at the outermost end in the gable direction. The rafters can be made into one piece while lowering the height of the gable, thereby increasing the strength of the outermost rafter, and the gable board can also be used as the outer rafter. The purpose is to provide side rafter support structure.

In the gable side raft support structure of the present invention, a cantilever beam 2 is placed and fixed on a girder side beam 1 such as a purlin, a purlin, or a girder so as to protrude outward in the gable side direction, and the outer end surface of the cantilever beam 2 is fixed. , the rafter bracket 3 is wider than this outer end surface.
A mounting hole 30 is drilled in a portion 5a of the mounting face plate 5 of the rafter bracket 3 located laterally than the outer end face of the cantilever 2, and a hole 30 is drilled under the mounting face plate 5. A pair of mounting pieces 6 are made to protrude outward from the edge in the girth direction so as to form a chevron shape when viewed from the outside, and a single piece of rafter 7 is placed on the mounting piece 6 of the rafter bracket 3, and the mounting hole 30 is The rafters 7 are fixed by driving the fixtures 4 in from the holes, and this structure achieves the above object.
That is, the mounting plate 5 of the rafter bracket 3 is attached to the outer end surface of the cantilever beam 2 in contact with the outer end face, and the mounting piece 6 is made to protrude outward from the lower edge of the mounting face plate 5 in the direction toward the end. Since a single rafter 7 is mounted and fixed on the cantilever beam 2, the lower edge of the rafter 7 is lower than the upper edge of the cantilever beam 2, making it possible to keep the height of the gable low.
One real rafter 7 can be installed, thereby improving the installation strength of the rafter 7 as a whole, and the rafter 7 can also serve as a gable board, and also can be used as a mounting face plate for the rafter bracket 3. 5
Since the pair of mounting pieces 6 protrude from the lower edge so as to form a chevron shape when viewed from the outside, the rafter 7 can be placed on either of the pair of inclined mounting pieces 6. Even if the rafter bracket 3 is attached to either the left or right end, the mounting piece 6 can receive the rafter 7, and the outer end face of the cantilever beam 2 has a raft wider than this outer end face. Mount the mounting plate 5 of the rafter bracket 3 in contact with each other, and drill a mounting hole 30 in a portion 5a of the mounting plate 5 of the rafter bracket 3 located laterally than the outer end surface of the cantilever 2. Rack 7 with fittings 4 inserted from 30
Since the mounting hole 30 is located on the side of the cantilever beam 2, the cantilever beam 2 does not get in the way when inserting the fixture 4 into the mounting hole 30, and the fixture 4 can be easily fixed to the rafters 7 and has excellent workability.
