Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an outer wall panel support structure capable of stably attaching an outer wall panel to a wall receiving beam between columns.

[Conventional technology]

By attaching an outer wall panel to a skeleton using a relatively large pillar made of square steel pipe, a house such as an apartment house with a plurality of floors, for example, three floors or more, is constructed by the pre-bab construction method. .

For example, in such a building, as illustrated in FIG. 4, in the process such as post-finishing the inner surface of the outer wall panel P, the outer surface B of the pillar A is separated from the outer surface B by a gap C. The panel P may be attached.

Conventionally, at this time, the outer wall panel P has its lower end supported by a wall receiving metal fitting E fixed to the upper surface of a wall receiving beam D connecting the columns A and A at the column center AO.

[Problems to be solved by the device]

However, in such a conventional outer wall panel support structure, the wall receiving beam D and the wall panel P passing through the pillar center AO are provided.
The horizontal length between and is large, so the wall bracket E that connects the two
Has a large overhang length l, which causes a large moment to act on the wall receiving beam D together with the metal fitting E, weakening the strength of the member and making the attachment unstable.

The present invention aims to provide an outer wall panel support structure which is basically provided with a wall receiving beam on the outward surface of a pillar, reduces the moment acting on the wall receiving metal fitting and the wall receiving beam, and helps stabilize the mounting. There is.

[Means for Solving the Problems]

According to the present invention, a wall receiving beam having a horizontal upper piece, which is fixed to the outward surface of the pillars, is bridged between the pillars made of square steel pipes and arranged side by side, and stands on a bottom piece fixed to the upper piece. The lower end of the outer wall panel is supported by the receiving piece of the wall receiving metal fitting provided with a receiving piece that horizontally extends outwardly beyond the outer edge of the bottom piece and the outer edge of the upper piece of the wall receiving beam via the lifting piece. This is the outer wall panel support structure.

[Action]

Since the wall receiving beam is fixed to the outward surface of the column, even when the wall receiving beam and the outer wall panel are arranged on the outward surface of the column with a gap, the outer wall panel and the wall receiving beam The horizontal length between the beams can be reduced. Therefore, the overhang length of the wall receiving fitting fixed to the wall receiving beam and supporting the outer wall panel can be reduced, and the moment acting on the wall receiving fitting and the wall receiving beam can be reduced. This makes it possible to reduce the reduction in member strength and to attach the outer wall panel in a stable manner.

〔Example〕

 An embodiment of the present invention will be described below with reference to the drawings.

In the figure, the outer wall panel support structure is a lower end of an outer wall panel P using a wall receiving metal fitting 5 fixed to an outer surface of the pillar 2 facing the outdoors and attached to an upper piece 4 of a wall receiving beam 3 connecting between the pillars 2. I support you.

The pillar 2 has a substantially rectangular base plate 11 attached to the lower end of a base body 10 made of a relatively large square steel pipe, and the base plate 11 is attached to an upper surface of an independent base (not shown) with anchor bolts at intervals. And the columns 2 are arranged side by side.

The wall receiving beam 3 includes a vertical piece 12 forming a web, an upper piece 4 which is an upper flange, and a lower piece 13 which is a lower flange.
The wall-bearing beam 3 is made of I-shaped steel and is mounted on the outer surface of the column 2, and is attached to the outer surface by using the lower fixing brackets 14 and 15.

The upper fixing member 14 has a mounting piece 17 that horizontally and outwardly extends to a lower edge of a base piece 16 that is bolted to the outward surface.
A stay is provided in the middle of the L-shaped frame provided with, and the mounting piece 17 is brought into contact with the upper piece 4 of the wall receiving beam 3 and both are bolted. Further, the lower fixing bracket 15 is the upper fixing bracket 14
And the lower piece 13 of the wall receiving beam 3 is bolted by its mounting piece 17, whereby the wall receiving beam 3 is
The inner surface is substantially in contact with the outer surface of the pillar 2 and is firmly fixed.

In addition, the wall receiving beam 3 is similar to the upper and lower fixing brackets 14 and 15
By including the right-angled outward surface of the pillar 2 located at the corner portion by using the bridge, the house frame is strongly reinforced by being bridged between the pillars 2.

The wall receiving fitting 5 has a bottom piece 1 as shown in detail in FIG.
6, a receiving piece 19 is provided via a rising piece 17, and the wall receiving metal fitting 5 has a rectangular plate shape, and its outer edge is aligned with the outer edge of the upper piece 4. The inner edge central portion of the bottom piece 16 has a shallow depth. The above-mentioned startup piece 17 which is vertically raised by cutting and raising with
Is formed and is formed as a bent body of a flat steel plate in which the receiving piece 19 that horizontally extends outward is provided on the upper end of the rising piece 17. As shown in FIGS. 1 and 3, the receiving piece 19 extends outward beyond the outer edge of the bottom piece 16 and the outer edge of the upper piece 4 of the wall receiving beam 3. The bottom piece 16 is fixed to the upper piece 4 by using bolts passing through the holes 20 provided on both sides of the bottom piece 16, and the holes 21 are arranged in parallel with the receiving piece 19, and the receiving piece 19 forms the outer wall panel P. Support the bottom edge.

The outer wall panel P is provided with an exterior material 23 on the outer surface of a frame 22 in which a groove made of a channel steel is arranged inwardly in a rectangular shape. The outer wall panel P is a lower frame material. Hole provided in
It is fixed to the receiving piece 19 with a bolt passing through the hole 21 of the receiving piece 19, and the lower end thereof is supported by the receiving piece 19.
The upper end of the outer wall panel P has a wall receiving beam 3A arranged above.
It is fixed to the lower piece via an L-shaped metal fitting 24.

After the outer wall panel P is attached, the interior material 25 using a gypsum board, a gypsum slab or the like is attached to the inner surface of the frame 22.

Further, in this example, as shown in FIG. 1, a form (not shown) arranged so as to surround the wall receiving beam 3 is used to surround the wall receiving beam 3 and rise from the underground stone 26. A cloth foundation concrete wall 27 is formed to reinforce the substructure of the framework.
Further, the wall receiving fitting 5 is filled with the mortar layer 29 extending to the outer surface and the inner surface of the concrete wall 27, and the caulking agent 30 is provided between the lower end of the interior material 25 and the mortar layer 29. Is installed.

As the wall receiving beam 3, various shaped steel materials having a horizontal upper piece 4 such as grooved steel can be used, and various modifications such as directly bolting the beam to the outward surface of the column 2 are possible.

[Effect of device]

Since the wall receiving beam is fixed to the outward surface of the column, the horizontal length between the wall receiving beam and the outer wall panel disposed with a gap between the wall receiving beam and the outward surface can be reduced. As a result, the horizontal overhang length of the wall receiving fitting fixed to the wall receiving beam and supporting the outer wall panel is reduced, so that the moment acting on the wall receiving fitting and the wall receiving beam can be reduced and the member strength is lowered. And the outer wall panel can be attached stably. Further, since the receiving piece of the wall receiving fitting is horizontally extended outward beyond the outer edge of the bottom piece and the outer edge of the upper piece of the wall receiving beam, for example, bolting for supporting the lower end of the outer wall panel on the receiving piece. The work can be performed in a wide space that does not interfere with the bottom piece and the lower piece, and the workability can be improved.
