Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to the structure of a cantilever attachment part when constructing a balcony or the like.

[Background technology]

Conventionally, when attaching a cantilever beam from a beam of a building to the outdoor side, there has been a drawback in that the connection portion between the beam and the cantilever beam has poor waterproof properties.

[Purpose of invention]

The present invention has been made in view of the above points, and it is an object of the present invention to provide a structure of a cantilever beam attachment part that can improve the waterproofness of the connection part between a beam and a cantilever beam and has good workability. The purpose is to

[Disclosure of invention]

That is, in the present invention, an opening 2 is provided in the exterior wall panel 1, an exterior cover 3 is attached to the outdoor surface of the exterior wall panel 1 so as to close the opening 2, and the connecting member 8 fixed to the beam 6 is connected to the exterior wall panel 1 from the indoor side. into the opening 2 of the bolt hole 4 provided in the exterior cover 3.
Cantilever beam installation is achieved by fixing the cantilever beam 7 to the outdoor side of the connecting member 8 with bolts 5 passed through the frame, and bending the lower edge of the exterior cover 3 toward the indoor side along the lower edge surface of the outer wall panel 1. The above purpose has been achieved through the structure of the section.

The present invention will be explained in detail below with reference to Examples. As shown in FIG. 1, a rectangular opening 2 is provided approximately at the center of the exterior wall panel 1, and an exterior cover 3 is attached to the outdoor surface of the exterior wall panel 1 so as to close the opening 2. A plurality of bolt holes 4 are provided in the exterior cover 3. On the other hand, a connecting member 8 is fixed to the beam 6 of the building as shown in FIG. It has been inserted. Align the bolt holes 9 of the connecting member 8 and the bolt holes 4 of the exterior cover 3, and fix the base of the cantilever beam 7 to the outdoor side of the connecting member 8 with the bolts 5 passed through both bolt holes 9 and 4. It has been done. In the figure, 10 is a nut. The lower end edge of the exterior cover 3 is bent toward the indoor side along the lower end surface of the outer wall panel 1. In the figure, 11 is a reinforcing plate that reinforces the cantilever beam 7, 12 is a flooring material, and 1
3 is a draining plate attached to the upper end of the outer wall panel 1, and a rising piece 14 stands up on the back side of the upper outer wall panel 1. Also, 15 is caulking material,
It is filled between the lower surface of the bent piece 16 of the exterior cover 3 and the draining plate 13, and between the outer wall panels 1 on the upper and lower floors.

Therefore, the cantilever beam 7 is connected to the beam 6 via the connecting member 8.
This allows the cantilever beam 7 to be firmly attached to the outer wall of the building. Further, an exterior cover 3 is attached to the outdoor side of the exterior wall panel 1 at the attachment portion of the cantilever beam 7, so that rainwater does not infiltrate into the interior through the openings 2, etc. of the exterior wall panel 1. In addition, the cut piece 16 at the lower edge of the exterior cover 3 is attached to the lower surface of the outer wall panel 1, and has good watertightness. In particular, the caulking material 15 filled between the bent piece 16 and the drain plate 13 and the rising piece 14 of the drain plate 13 can reliably prevent rainwater from entering the interior. In addition, when attaching this exterior wall panel 1 to the exterior wall, by aligning the bent pieces 16 of the exterior cover 3 with the upper end surface of the lower exterior wall panel 1, the bolt holes 4 are aligned with the connecting members 8. can be aligned with the bolt hole 9 of the cantilever beam 7
can be easily fixed.

[Effect of idea]

As mentioned above, in this invention, the connecting member fixed to the beam is inserted into the opening of the exterior wall panel, and the cantilever beam is fixed to the connecting member with the bolt passed through the bolt hole of the exterior cover. A cantilever beam can be easily and firmly attached to a beam by simply tightening it, and an exterior cover is attached to the outdoor side of the exterior wall panel to cover the opening, and the lower edge of the exterior cover is attached to the lower edge of the exterior wall panel. Since it is bent toward the indoor side along the outer cover, it is possible to prevent rainwater from flowing to the back side of the outer cover and improve watertightness.

[Brief explanation of the drawing]

FIG. 1 is a perspective view of an embodiment of the present invention, and FIG. 2 is a sectional view of the same essential parts. 1 is an exterior wall panel, 2 is an opening, 3 is an exterior cover, 4 is a bolt hole, 5 is a bolt, 6 is a beam, 7 is a cantilever beam, and 8 is a connecting member.

Claims (1)

[Scope of utility model registration request] An opening is created in the exterior wall panel, an exterior cover is attached to the outdoor side of the exterior wall panel to close the opening, a connecting member fixed to the beam is inserted into the opening in the exterior wall panel from the indoor side, and a bolt is attached to the exterior cover. The structure of the cantilever attachment part consists of fixing the cantilever to the outdoor side of the connecting member with bolts passed through the holes, and bending the lower edge of the exterior cover toward the indoor side along the lower edge of the outer wall panel.
