The outer wall panel 5 whose back portion 5b is attached and fixed to the framework 1 is made of concrete. The dimensions of the exterior wall panel are, for example, approximately 50cm in width and 300cm in height.
The thickness is approximately 5-6 cm. As shown in FIG. 1, it is easier to work by attaching four outer wall panels 5 to the framework 1. That is, it is preferable to attach two outer wall panels from the vertical column 1c to the middle column 1e, and two outer wall panels from the middle column 1f to the vertical column 1d. The relationship between the frame 1 and the outer wall panel 5 changes depending on the shape and dimensions of the building. The width of the framework 1 may be half or one-fourth of that shown in FIG. The outer wall panel 5 has a hollow portion 5a that vertically penetrates inside.

The mounting bracket 6 is formed by integrally forming a mounting plate 7 and a support plate 8 into a substantially T-shape. The lower end of the mounting plate 7 is bent and protruded in the opposite direction to the support plate 8, and serves as a locking piece 7a on which the lower end 5c of the outer wall panel 5 is placed. A through hole 7b is formed in the upper part of the mounting plate 7, and a bolt shaft 11 with an engaging member 10 attached to the tip thereof is formed.

The lower end 5c of the concrete outer wall panel 5 with the back 5b attached to the framework 1 is placed on the locking piece 7a provided at the lower end of the mounting plate 7 of the mounting bracket 6. A vertically long hole 19 is formed that reaches the hollow part 5a from the back part 5b near the lower end of the outer wall panel 5, and the engaging member 10 provided at the tip of the bolt shaft 11 inserted through the mounting plate 7 is inserted from the vertically long hole 19 into the hollow part 5a. inserted into. When the bolt shaft 11 is rotated to lock the engaging member 10 inside the hollow portion 5a, and the nut 12 is screwed into the bolt shaft 11 protruding from the mounting plate 7 and tightened, the engaging member 10 locks the outer wall panel. 5
is attracted to the mounting plate 7. In this way, the outer wall panel 5 is attached to the framework 1 via the attachment fittings 6.

In addition, the outer wall panel 5 is made of concrete,
The panel may be made of not only inorganic materials, but also a mixture of inorganic and organic materials, or foamed concrete.

Further, it is preferable to form long grooves in the vertical direction at appropriate intervals in the back part 5b of the outer wall panel 5 so as to allow ventilation in the vertical direction on the inner surface of the wall body. Further, the hollow portion 5a is formed in consideration of the strength of the panel, but it is formed so that the outer wall panel 5 can be made as lightweight as possible.

(Effects of the invention) As described above, according to the invention, the lower end of the hollow outer wall panel can be attached to the framework extremely easily and efficiently.

Specifically, since the concrete exterior wall panel has a hollow part inside, the engaging member provided on the mounting plate of the mounting bracket is inserted into the vertical hole formed from the back near the lower end to the hollow part. In addition, since the lower end of the exterior wall panel is placed on a locking piece provided on the mounting plate, it can be easily attached to the exterior wall panel and mounting brackets without damaging the appearance of the exterior wall panel or using fixing means such as bolts. can be connected. The vertically elongated hole may be formed from the back of the outer wall panel to the hollow part.

To fix the frame and the mounting bracket, a clamping plate that is engaged with the support plate of the mounting bracket is inserted into the groove of the lower chord of the frame, and the clamping plate and the support plate are connected to the edges on both sides of the opening of the lower chord. Because it is done by holding the pieces together,
Its fixing work is easy. Moreover, the support plate can be easily fixed perpendicularly to the lower chord member. Because the mounting bracket is fixed to the bottom chord by sandwiching the edge pieces on both sides of the opening of the bottom chord between the support plate and the clamping plate, large loads such as those from concrete exterior wall panels will not be applied to the mounting bracket. Even if the mounting bracket is subjected to stress that causes it to twist in the outdoor direction, it can be securely held and fixed.

Furthermore, since the lower end of the outer wall panel is received by the locking piece provided at the lower end of the mounting plate of the mounting bracket, the heavy concrete outer wall panel can be reliably supported and fixed.
