Description

[Detailed explanation of the invention] [Technical field] This invention is based on the L
This relates to the frame structure of the eaves in the corner areas with the addition of letter-shaped purlin support hardware.

[Background Art] Conventionally, as shown in FIG. 4, the frame structure of the eaves at the corner of a building is such that cantilevers 4 are connected to the other main body beam from above the module line L of both body beams 1. The main building 3 was placed on the projecting end 4a of the cantilever beam 4, and the ends of the main building 3 were connected to each other by an angle member 14. If it is large, the weight of the end of the main building 3 supported by the cantilever beam 4 will be large, and there will be concerns about its strength.

[Purpose of the invention] The present invention was made in view of the above circumstances, and its purpose is to create an L-shaped structure on the main beam of the entrance corner in the frame structure of the eaves at the entrance corner of the building. By attaching the main building support hardware, the main building can be supported regardless of the module pitch and a strong structure can be achieved.

[Information on the invention] The frame structure of the eaves at the entrance corner of the building of the present invention is such that an L-shaped purlin support bracket 2 is attached to the corner part of the main body beam 1 at the entrance corner A of the building. The end of the main building 3 is placed and fixed on one side of the hardware 2, and the cantilever 4 is made to protrude from the other side of the main building receiving hardware 2, and the protruding end 4a of the cantilever 4 is crossed over the main building 3 to secure the main building. 3, and the corner purlin 5 is located below the projecting end 4a of the cantilever beam 4.
The end portion of the holder is placed and fixed, and with this configuration, the above object can be achieved. That is,
The purlin support hardware 2 can support the purlin 3 regardless of the module pitch.

The present invention will be described below based on embodiments shown in the accompanying drawings. A main body beam 1, which is an assembly beam, is installed at the corner A of the building via pillars 6. A purlin support metal fitting 2 made of channel steel and having an L-shape in plan view is attached to the corner portion of the main body beam 1. Both ends of the purlin support hardware 2 are each fastened to the web plate 7 of the main body beam 1 with bolts 8, and the corner portion is fastened to the pillar 6 with bolts 10 via a support angle 9. An end of a purlin 3 made of H-shaped steel is placed on an upper flange 2a on one side of the purlin receiving hardware 2, regardless of the module line L, and is fixed with bolts 11 at a lower flange 3b. Further, on the other side of the purlin receiving hardware 2, one end of a cantilever beam 4 made of H-shaped steel is fixed with a bolt 12 via a connecting plate 11 at a web 4a, regardless of the module line L. This cantilever beam 4 protrudes parallel to one side of the purlin support hardware 2, and the protruding end 4a intersects the purlin 3 at right angles, and is located below the purlin 3 so that its upper surface is connected to the lower flange 3b of the purlin 2. The end of the corner purlin 5 of the building made of H-shaped steel, which is the same as the purlin 2, is placed on the upper surface of this projecting end 4a and welded to the upper surface of the upper flange 5a of the inner corner purlin 5. is flush with the upper surface of the upper flange 3a of the main building 3. Panel bodies 13 and the like are erected on the main body beam 1 of the frame constructed in this manner to form a roof frame, and a roofing material (not shown) is covered thereon to constitute an eaves.

[Effects of the invention] In the present invention, the end of the purlin is placed and fixed on one side of the purlin bracket attached to the corner of the main body beam at the entrance corner of the building, and the other side of the purlin bracket is fixed. The cantilever beam is made to protrude further, and the protruding end of the cantilever beam crosses the main house and is positioned below the main house, and the end of the corner purlin is placed and fixed on the protruding end of the cantilever beam. So,
It is possible to support the main house and the corner purlin regardless of the module line, and therefore the structure can be strong even if the eaves can be freely changed.
