The reinforcing member (10) is provided at a corner portion formed by the upper surface of (1) to prevent the corner portion from being deformed.

(Operation) By adopting the above means, each component of the present invention operates as follows.

First, the rod-shaped member (6) inserted into the tip portion of the base block portion (3) prevents the anchor body (1) from trying to come out of the precast concrete curtain wall (12).

Since the basic block portion (3) is formed so that its vertical cross section is a rectangular shape that is long in the vertical direction, it does not bend under the weight of the precast concrete curtain wall (12).

The plate-shaped part (2) is located between the base block part (3) and the attachment block part (4) and is the anchor body (1).
Since the base block portion (3) is embedded so as to be in contact with the precast concrete curtain wall (12), the mounting block portion (4) becomes precast concrete. The curtain wall (12) is projected orthogonally. As a result, if the precast concrete curtain wall (12) is fixed to the steel beam (11) through the mounting block part (4), the precast concrete curtain wall (12) has an accurate angle with respect to the steel beam (11).

As a result, the mounting anchor metal piece has a low cost, requires a small construction space, and has sufficient mounting strength against the weight of the PC curtain wall 12 and the load during a strong wind or earthquake.

Further, conventionally, since the load of the PC curtain wall could not be received by the anchor metal, the wall thickness of the lower portion of the PC curtain wall is made thicker to support this portion from below. There is a drawback that the volume of the room becomes smaller as the thickness increases. In this respect, in the present embodiment, since the load of the PC curtain wall 12 can be supported by the mounting block portion 4 extending from the PC curtain wall 12, the wall thickness of the PC curtain wall 12 is partially reduced as in the conventional case. There is no need to make it thick, and a large interior volume can be secured accordingly.

In this embodiment, since the base block portion 3 and the mounting block portion 4 are made of different steel materials, the dowel 8 integrally formed with the mounting block portion 4 is fitted into the fitting hole 9 of the plate-shaped portion 2. By doing so, the bonding strength was increased. However, the present invention is not limited to this, and various modifications can be made without departing from the spirit of the present invention, for example, the base block portion and the mounting block portion may be formed integrally.

[Advantages of the Invention] As described in detail above, the present invention is a mounting block portion (4) having a relatively flat, small, and simple structure, but it is possible to increase mechanical strength, so that construction can be performed at low cost. There is an effect that the space is small, and moreover, sufficient mechanical strength can be obtained against the weight of the PC curtain wall and the load at the time of strong wind / earthquake, and the mounting strength of the PC curtain wall can be significantly increased. .
