[0004]

[Problems to be Solved by the Invention] By the way, the thickness of the pillar 1 varies depending on the design specification of the building. However,
In the above configuration, since the ruler angle 2 is directly welded to the column 1, the size between the ruler angles 2 differs depending on the thickness of the column 1. If the dimensions are different, the dimensions between the mounting plates 5 are different, and thus the ALC panel 3
The dimensions between the insert nuts 4 buried in each other will also differ. For this reason, if the conventional ALC panel mounting structure is adopted, after all, according to the design specification of the building, the AL
It is necessary to make the insertion position of the insert nut 4 in the C panel 3 different, and various types of ALC
There was a problem that the panel 3 had to be manufactured.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a concrete panel mounting structure capable of mounting a standardized concrete panel even if the pillars have different thickness dimensions. is there.

[0006]

The mounting structure of the present invention comprises a mounting member buried on the concrete panel side, an auxiliary hardware fixed to the pillar side of the skeleton by welding, and the auxiliary metal and the mounting member. And a ruler angle connected by welding, wherein the auxiliary hardware has a substantially U-shaped cross section in which a pair of welding surfaces are formed on both side surfaces facing each other at a fixed interval, and is formed on a facing surface of the concrete panel in the column. The ruler angles are attached to both side surfaces of the auxiliary hardware, respectively, and the ruler angles are opposed to each other by a certain distance with the auxiliary hardware as a spacer. It is characterized by the following.

[0007]

The two ruler angles extend vertically and are welded to the welding surface of the auxiliary hardware fixed to the pillar, and the concrete panel is fixed to the ruler angle via the mounting member.
Here, since the welding surfaces of the auxiliary hardware are opposed to each other with a predetermined interval therebetween, the dimension between the two ruler angles welded here is always constant regardless of the thickness dimension of the column. become. Therefore, the position of the mounting member buried in the concrete panel may always be constant and can be standardized.

[0008]

As described above, according to the concrete panel mounting structure of the present invention, the position of the concrete panel mounting member can be constant regardless of the thickness of the pillar.
This has the effect that the specifications of the concrete panel can be standardized.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to a lateral wall construction method in which an ALC panel is constructed as an outer wall of a building will be described below with reference to FIGS.

FIG. 1 shows a state in which the ALC panel 11 is attached to a frame as viewed from the outside of a building. In the case of this embodiment, a square steel is used as the pillar 12 of the skeleton, and a plurality of auxiliary hardware 13 are intermittently fixed here. The fixed interval is such that the width of the ALC panel 11 is 600 mm.
Is, for example, 600 mm to 900 mm.

As shown in FIG. 4, the auxiliary hardware 13 has base portions 13a extending in opposite directions to the opening side of the U-shaped cross section.
And has a pair of welding surfaces 13b facing each other at a predetermined interval D (about 50 mm in this embodiment), and has a length of about 100 mm in this embodiment. And the bottom 13a is the pillar 12
Are fixed to each other on the outer wall side of the building by extending along the columns 12.

A ruler angle 14 made of L-shaped steel is fixed to each welding surface portion 13b of the auxiliary hardware 13 so as to extend vertically by welding.

On the other hand, the ALC panel 11 is of a standardized specification. As shown in FIG. 3, two insert nuts corresponding to a mounting member are provided at a position deviated by a predetermined dimension X inward from both ends in the longitudinal direction. 15 are respectively buried. These insert nuts 15 are used for the ALC panel 11
It is buried at the time of manufacturing, for example, it is integrated with a reinforcing bar (not shown) inside and stored in a molding die. ing.

Each insert nut 15 has a bolt 1
6 are screwed together, thereby fixing two stepped mounting plates 17 called “inazuma plates” to both ends of the ALC panel 11. These stepped mounting plates 17 are shown in FIG.
As shown in the figure, the tip is welded with the ruler angle 14 sandwiched between the ALC panel 11 and the ALC panel 11 is thereby welded to the ruler angle 14 and thus the column 12.
It is in the state attached to.

The stepped mounting plate 17 is fixed by bolts 16 via square washers 18 and the stepped mounting plate 1
The bolt insertion holes 17a formed in the upper and lower parts 7 are vertically long, so that even if an interlayer displacement occurs in the frame due to an earthquake or strong wind, an excessive force is not applied to the ALC panel 11.

Next, the ALC panel 11 having the above configuration
The work procedure for fixing the to the frame is described.

First, the auxiliary hardware 13 is intermittently welded and fixed to the pillar 12 of the skeleton. Next, two ruler angles 14 are welded to both welding surfaces 13b, 13b of each auxiliary hardware 13 by using a down swing or the like so as not to be inclined. Meanwhile, AL
Insert nuts 1 near both ends of C panel 11
A bolt 16 is screwed into 5, and two stepped mounting plates 17 are loosely mounted. Then, the ALC panel 11 is lifted by a crane or the like, and
6 is tightened, and each stepped mounting plate 17 is welded to the ruler angle 14, whereby the mounting of the ALC panel 11 is completed.

In the above-described embodiment, the sub hardware 1
3 is a standardized constant value between the two welding surface portions 13b, so that the two ruler angles 1 welded here
The spacing dimension 4 is also a constant value irrespective of the thickness of the column 12.
For this reason, a fixed position can be used for the embedding position of the two insert nuts 15 provided on the ALC panel 11 irrespective of the thickness of the column 12.

For example, a pillar 2 thicker than that shown in FIG.
0 shows a state in which the ALC panel 11 is attached, as shown in FIG.
ALC panel 1 with the same specifications as in FIG.
It is clear that one is available.

This means that ALC panels of the same specifications can always be used, even if the thickness of the pillars varies depending on the design specifications of the building, and many types of ALC panels can be manufactured. Means that they no longer need to be in stock. As a result, the specifications of the ALC panel can be standardized and mass-produced, whereby the manufacturing cost can be reduced and the product management can be rationalized.

The present invention is not limited to the embodiment described above and shown in the drawings. For example, the present invention can be implemented with the following modifications.
