DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cubic mounting structure constituting a cubic curtain wall.

[0002]

2. Description of the Related Art A cubic curtain wall is one in which a square frame is formed by bridging a gap between cubicles attached to a building frame, and panels are mounted on the rectangular frame. A plurality of locations in the direction are attached to the building frame via a plurality of fasteners.

[0003]

With such a cubic mounting structure, the building frame can be extended over a long distance in the in-plane direction from the floor to the ceiling, like the opening of the entrance hall of the building. Since a large opening cannot be fitted with a cubic curtain wall, the large opening cannot be closed with a cubic curtain wall.

It is an object of the present invention to provide a cubic curtain wall mounting structure which can solve the above-mentioned problems.

[0005]

The upper portion of the cubicle 20 is attached to the ceiling 18 via a bracket 60 so that the cubicle 20 is attached to the ceiling 1.
8, one end of a pair of cables 28 in the in-plane direction is connected to both sides of the outside of the plane near the lower end of the screen 20 via a screen fastener 80, and the other end of each cable 28 is connected to the other side. A cubic curtain wall mounting structure in which the cable 28 is connected to the ceiling 18 by the ceiling fastener 81 and the cable 28 is diagonally stretched in the in-plane direction and the out-of-plane direction on the ridge 20 and the ceiling 18.

[0006]

[Operation] Since the cubicle 20 is suspended from the ceiling 18 and supported, the cubicle is attached to a large opening where there is no building frame for a long distance in the in-plane direction between the floor and the ceiling. The part can be closed with a cubic curtain wall, and the cubic 20 is supported by a pair of in-plane cables 28 which are obliquely stretched in the in-plane and out-of-plane directions.
Of the cubic 20 in the in-plane direction and the out-of-plane direction due to the wind pressure acting on the ridge 20 can be prevented.

[0007]
