A receiving member formed of a horizontal piece and an upright piece provided with a hole at a position perpendicular to the horizontal piece and in contact with the base material is attached to the base material, and a plurality of receiving metal members are provided for the receiving metal member. A mounting structure for a horizontal wall panel, wherein the wall panel is mounted.

According to the first aspect of the present invention, a hole is provided in the upright piece of the receiving member including the horizontal piece and the upright piece, and a predetermined position of the upright piece provided with the hole is brought into contact with the base material. By using this hole, the receiving fitting can be fixed to the base material by welding or bolting, and the mounting operation can be simplified.

In particular, according to the first aspect of the present invention, the upright piece of the receiving fitting can be widely contacted with the underlying material, and the receiving fitting can be attached to the underlying material in a stable state.
The mounting strength can be significantly increased. In addition, not only the angle material but also an inexpensive flat bar can be used as the base material.

When a bolt hole is provided in the base material, by aligning the bolt hole with the hole of the standing piece of the receiving bracket, the two can be connected at a simple and accurate position via the bolt. . In this case, the welding operation can be completely eliminated.

According to the first aspect of the present invention, since a plurality of wall panels are attached to one receiving fitting, the number of receiving fittings and the labor required for mounting can be reduced by half.

When the wall panel is attached to the base material,
Since a gap corresponding to the thickness of the flat plate used for fixing the O-bolt on the wall panel side is formed between the wall panel and the base material, conventionally a gap filling liner was used for this gap portion. In the case where the metal fitting having the upright piece is used as in the first invention, the upright piece serves as a gap filling liner, so that the gap filling liner is not required. In particular, in the case of using a T-shaped receiving metal fitting in which the standing piece extends downward, the upper and lower gap filling liners can be eliminated.

A mounting structure for a horizontal wall panel according to the first invention, characterized by the following.

In the second aspect of the present invention, the corner of the portion where the reinforcing bar of the wall panel does not exist inside does not contact the horizontal piece of the receiving bracket, that is, is surrounded by the reinforcing bar of the wall panel. Since the horizontal part of the bracket is used to receive the broken part, it is possible to prevent the corner of the wall panel from being damaged during an earthquake.

In particular, even when the mounting accuracy of the receiving bracket attached to the base material is poor, the corners of the relatively weak wall panel do not make point contact with the horizontal pieces of the receiving bracket.
The corners of the wall panel are less likely to crack.

The gist of the third invention of the mounting structure of the present invention is that the horizontal wall of the first invention or the second invention is characterized in that a plurality of holes are provided in the up and down direction of the standing piece of the receiving fitting. Panel mounting structure.

In the third aspect of the present invention, since a plurality of holes are provided in the vertical direction of the standing piece of the receiving metal,
By utilizing these holes, the receiving bracket can be attached and fixed to the base material at two locations, and thereby the base material can be firmly mounted and fixed by the receiving bracket.

The receiving bracket can be attached to the base material in a stable state. Further, by using the holes of the upstanding pieces, the receiving bracket can be attached to the base material not only by welding but also by bolting. In the case of mounting by welding, the inner peripheral lower edge of the hole can be particularly welded, so that the welding operation is stable and easy.

As described above, the number of base materials interposed between the skeleton and the receiving metal can be reduced to one, so that the time and labor required for mounting and the material cost can be reduced by half. The base material is flat (F
In the case of B), the effect can be further enhanced.

Since the wall panels on both the left and right sides can be supported by using one receiving fitting, the number of receiving fittings used for the entire building can be reduced, and the weight, material cost and installation labor are reduced by half. You can do it. In addition, since the standing piece of the receiving fitting is interposed in the gap between the wall panel and the base material, the gap filling liner inserted into the gap can be unnecessary.

When supporting the wall panel with the horizontal piece of the receiving bracket, use a horizontal piece with a missing central part or use a plate-shaped liner to remove the panel corner where there is no reinforcing bar inside the panel. By supporting the portion at the inside of the wall panel, that is, by making the corners and the receiving fittings out of contact, it is possible to prevent the wall panel from being chipped or damaged during an earthquake or the like. Even when the mounting accuracy of the receiving bracket is poor, it is possible to prevent cracks or chipping at corners of the wall panel.
