Description

[Detailed explanation of the idea] 【Technical field】

The present invention relates to a structure for attaching corner bundles for extending the climbing beams of the roof of the single-story roof from the inside corner of the outer wall of the large wall structure in the wall-horizontal roof assembly part of a partially single-story steel-frame prefabricated house.

[Background technology]

In the conventional construction method for large walls, the exterior wall panel 2 for the lower house is used where the corner bundle 4 is installed, and the exterior wall panel 2 is then covered with exterior material 2a, as shown in Figure 4. The exterior material 2a with the lower end cut out is stretched so that the outer surface of the cutout portion 5 is almost aligned with the outer surface of the beam 1, and the lower end of the corner bundle 4 is directly attached to the outer surface of the beam 1 with bolts, etc., and the inner corner bundle is assembled. The upper end of 4 was housed in the notch 5. For this reason, in this part, an exterior wall panel 2 for the lower building and a special exterior material 2a having various cutout parts 5 are required, and the number of types of exterior materials 2a and exterior wall panels 2 increases, increasing component costs. There was a problem. Also,
Since the exterior material 2a is attached to the exterior wall panel 2 later, the number of joints between the exterior materials increases, the number of places filled with caulking material, etc. increases, and there is a problem that the construction time is increased.

[Purpose of invention]

The present invention was developed in view of the technical background described above, and its purpose is to attach corner bundles to support the climbing beams of single-story buildings on the outer wall of a large wall structure. In terms of structure, the objective is to reduce the number of types of exterior wall panels and exterior materials with a simple structure, and to suppress the occurrence of joints.

[Disclosure of invention]

In the mounting structure of the corner bundle according to the present invention, a pair of channel materials 10 are vertically opposed to each other in the outer wall part of a large wall structure where the outer surface of the outer wall panel 2 erected on the beam 1 extends beyond the outer surface of the beam 1. to configure the beam 1,
A pair of approximately Z-shaped spacers 3 having a thickness equal to or greater than the protruding length of the outer wall panel 2 are provided in the inner corner bundle 4, and a fork-shaped recessed portion 11 integrally provided at the tip of one of the spacers 3 is attached to one channel material. Another fork-shaped biting part 11 is fixed to the other spacer 3 by fastening with bolts and nuts 13, and the biting part 1 fixed to the other spacer 3 is fixed to the other spacer 3.
1 is fitted to the side piece 10a of the other channel material 10, the corner bundle 4 is attached to the beam 1, and the upper part of the corner bundle 4 is arranged along the outer surface of the outer wall panel 2. This is a characteristic feature. Therefore, since the spacer 3 allows the inner corner bundle 4 to be attached away from the outer surface of the beam 1, the inner corner bundle 4
Ordinary exterior wall panels 2 are used even in areas where
This eliminates the need for exterior wall panels that can be later covered with exterior wall materials that have cutout portions as in the past, reducing the number of types of exterior wall panels 2, etc., and using regular exterior wall panels 2. Therefore, the number of joints on the exterior wall can be reduced compared to conventional construction methods. Furthermore, when attaching the corner bundle 4, it is only necessary to fit the biting part 11 of the spacer 3 into the side piece 10a of the channel material 10 of the beam 1, so that the corner bundle 4 can be installed easily and quickly. Construction can be carried out. Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The beam 1 constructed at the corner of the outer wall is a lattice beam, and a pair of channel materials 10 are installed with the groove sides facing each other.
are arranged one above the other, and a lattice member (not shown) is stretched between the upper and lower channel members 10. As shown in FIG. 3, a base metal fitting 6 is fixedly installed on the upper surface of the beam 1, and the outer wall panel 2 is erected in such a manner that the base metal fitting 6 is fitted into the groove 7 on the lower surface. This outer wall panel 2 is of a large wall type, and its outer surface protrudes beyond the outer surface of the beam 1, but unlike the conventional example, a notch is not provided. The inner corner bundle 4 is formed of angle steel to a suitable length, and a horizontal top plate 9 is welded to the upper end. A pair of upper and lower spacers 3 as shown in FIG. 2 are provided on both back sides of the corner bundle 4, respectively. (Although FIGS. 1 and 2 only show the spacer 3 on one side of the corner bundle 4, the side of the spacer 3 that is not visible in the drawings has a similar structure.) The thickness of this spacer 3 is equal to or slightly larger than the protruding length of the outer wall panel 2 from the outer surface of the beam 1. A fork-shaped biting part 11 is formed at the welded tip so that the side piece 10a of the channel material 10 can be grasped. Further, the upper spacer 3 is composed of a step-shaped fixing piece 12 welded to the inner corner bundle 4 and a biting part 11 cut and raised in a fork shape so as to be able to grip the side piece 10a of the channel material 10. The recessed portion 11 can be attached to the fixing piece 12 using bolts and nuts 13. Therefore, the procedure for attaching the inner corner bundle 4 can be easily carried out, for example, as follows. First, loosen the bolt and nut 13 that attach the recessed part 11 of the upper spacer 3 so that the recessed part 11 rotates around the bolt. In this state, hold the corner bundle 4 at the corner of the outer wall as shown in FIG. vertically, and then the biting part 11 of the upper spacer 3
Rotate and fit it into the side piece 10a of the upper channel material 10, and then tighten the bolt and nut 1 of the upper spacer 3.
3 is tightened to prevent the biting portion 11 from rotating, the corner bundle 4 is fixed, and the upper part of the corner bundle 4 is arranged along the outer surface of the outer wall panel 2, as shown in FIG. Note that a partial flat roof is formed below the corner of this outer wall, and the flat corner bundle 4 is made to support the upper end of a frame member such as a climbing beam of the partial flat roof.

[Effect of the idea]

As described above, in the outer wall portion of a large wall structure, the present invention constructs the beam by vertically opposing a pair of channel materials, and inserts a pair of approximately Z-shaped spacers having a thickness equal to or greater than the protruding length of the outer wall panel. Installed in the corner bundle,
A fork-shaped biting part provided integrally at the tip of one spacer is fitted into the side piece of one channel material, and another fork-shaped biting part is fixed to the other spacer by fastening with bolts and nuts. The recessed part fixed to the other spacer is fitted into the side piece of the other channel material, and the inner corner bundle is attached to the beam, and the upper part of the inner corner bundle is arranged so as to follow the outer surface of the outer wall panel. , the corner bundle can be installed away from the outside surface of the beam using a spacer, and normal exterior wall panels can be used even in the place where the corner bundle is erected, and the exterior wall material with the cutout part can be installed later as in the conventional case. This eliminates the need for removable exterior wall panels, which has the advantage of reducing the number of types of exterior wall panels and reducing component costs. In addition, since regular exterior wall panels are used, the number of joints in the exterior wall can be reduced compared to conventional construction methods, and the labor involved in caulking the joints and other construction work can be reduced. Furthermore, when installing the corner bundle, you can loosen the bolt and nut that attaches the biting part of the other spacer so that the biting part rotates around the bolt. , and tap the biting part of one spacer into the side piece of the lower channel material to stand up the corner bundle, then insert the biting part of one spacer into the side piece of one channel material. It is possible to perform the work of biting and tightening bolts and nuts, and there is an advantage that the corner bundle can be installed easily and quickly from the front even in corner spaces where space is narrow and construction is difficult.
