Among the above-described mounting of the lower part of the wall panel, in the former, it is difficult to adjust the entrance and exit of the wall panel in the out-of-plane direction, and in the latter,
There is the complexity of setting the height position of the wall panel by operating the height adjustment bolt.

Generally, in a building of a curtain wall construction method, a mounting body of a wall panel is composed of a beam material such as H-section steel, a column material, or the like. It is well known that these steel materials have variations in accuracy such as linearity and flatness as members. In terms of the flatness of the wall panel, particularly in the case of a panel made of a precast concrete slab, the larger the slab, the more it is subject to physical influences and the like so that the flatness may slightly vary.

Therefore, when the wall panel is attached to the frame made of these steel materials, considering the construction technique such as workability, the metal as an inclusion has a function of adjusting the entrance / exit to the outside of the wall and a high function. It is more preferable to provide a height adjustment function. Also, the adjustment function in this case is
It goes without saying that what can be easily set without requiring so-called skill is desirable in terms of construction technology. If these adjustment functions are not provided, the structure will be simple, but high precision is required for the precision of the mounting hardware itself, the mounting position of the support angle, etc., and an extremely high level of on-site construction technology is also required. Therefore, there is a problem that the construction cost is shortened and the overall construction cost is likely to be adversely affected.

The present invention has been made in view of the conventional problems as described above, and an object of the present invention is to enable the entrance and exit of a wall panel and the height adjustment thereof with an extremely simple structure, and An object of the present invention is to provide a mounting device having sufficient proof strength against stress such as pressure.

The present invention is a mounting device that is mounted on a lower portion of a wall panel and is engaged and fixed to a support angle fixed to a skeleton, wherein an engaging piece is made to project from an intermediate portion of a back plate to have a substantially T-shape in a plan view,
The engaging piece is formed with an engaging groove, which is wider than the plate thickness of the supporting angle and opens downward, in the intermediate surface portion in the projecting direction thereof, and the lower end of the fitting has a mounting height reference end and the engaging piece described above. And a wedge plate that is interposed between the one piece and the upright piece of the support angle to fix the both pieces.

In this case, the protruding tip edge of the engaging piece may be expanded in a direction substantially perpendicular to the protruding direction to form a reinforcing rib piece.

Further, the metal body is formed into a substantially T-shape in plan view in which one piece of the L-shaped metal piece is surface-bonded to each other and the piece of this joint is used as an engaging piece, and the other piece which is not bonded is used as a back plate. It is also possible to form.

Furthermore, the metal body is bent by combining a single rectangular plate at the intermediate portion, and the bent portions are left at required widths, and the ends are bent at right angles to opposite sides to form a back plate. It is also possible to form the bent alignment portion as an engaging piece in a substantially T shape in a plan view.

[0013]
