DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for attaching a curtain wall unit constituting a unit type curtain wall to a building frame.

[0002]

2. Description of the Related Art A unit-type curtain wall has a plurality of curtain wall units attached to a building frame continuously in the vertical and horizontal directions, and there are various structures for attaching the curtain wall unit to the building frame. Are known. For example, a frame-side fastener having a supporting horizontal axis is attached to a building frame, and unit-side fasteners that engage with the supporting horizontal axis are respectively attached to left and right vertical frames of the curtain wall unit. The curtain fastener unit is attached to the building frame by engaging the side fasteners with the horizontal axis of one of the frame side fasteners.

[0003]

With such a curtain wall unit mounting structure, the unit side fasteners are mounted on the left and right vertical frames of the curtain wall unit, respectively, so that the number of fasteners increases, and the fastener mounting work and the mutual operation of the fasteners are performed. Since the engaging work is troublesome, the installation of the curtain wall unit takes a long time and is not efficient.

Accordingly, an object of the present invention is to provide a curtain wall unit mounting structure capable of solving the above-mentioned problems.

[0005]

A panel 10 is mounted on a frame 9 in which a left vertical frame 2, a right vertical frame 3, an upper frame 4 and a lower frame 5 are framed in a rectangular shape.
Is attached to the curtain wall unit 1, and one vertical frame 2 of the curtain wall unit 1 is
1, and the other vertical frame 3 side of the curtain wall unit 1 can be relatively displaced in the in-plane direction to one vertical frame 2 side of the curtain wall unit 1 adjacent to the curtain wall unit 1. A mounting structure for the curtain wall unit, which is in contact with the curtain wall unit so as not to move downward.

[0006]

[Operation] Of the left and right loads of the curtain wall unit 1, the downward load on one side is transferred to one vertical frame 2 and the fastener 1.
1, the downward load of the other side of the curtain wall unit 1 can be supported by the building frame a via the one vertical frame 2 and the fastener 11 of the adjacent curtain wall unit 1, The adjacent curtain wall units 1 and 1 can be relatively displaced in the in-plane direction.

[0007]
