DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel frame of a curtain wall panel unit constituting a panel unit together with a panel body constituting an outer wall surface of a curtain wall, for example.

[0002]

2. Description of the Related Art A panel unit for a curtain wall includes a panel body such as a metal plate having a certain strength and a design property for forming an outer wall surface, and rivets or rivets on a panel frame for maintaining the rigidity of the panel body. It is configured by bonding with an adhesive or the like. The panel frame supports the panel body so as to sufficiently withstand wind pressure. Conventionally, in general, the left and right vertical frames are generally formed by forming an upper frame and a lower frame into a rectangular shape.

[0003] On the other hand, in a unit-type curtain wall or the like which does not use a blind eye, a panel unit is used as a waistboard on each floor, and panel units and glass are alternately arranged vertically to form an outer wall surface. In such a case, the upper frame and the lower frame of the panel unit also serve as the lower frame of the glass located immediately above and the upper frame of the glass located immediately below, respectively. In this case, the glass is supported by the upper frame of the panel unit, that is, the pair of left and right setting blocks provided in the swallowing groove of the upper frame of the panel frame, as in the case where the glass is incorporated into a normal frame. It is fitted into the frame.

[0004]

In the above-described panel frame of the conventional curtain wall panel unit, the weight of the glass located immediately above is received by the upper frame via the right and left setting blocks, and the upper frame is received by the upper frame. From the upper frame to the left and right vertical frames that are supported by both sides. For this reason, the upper frame receives a bending load due to the weight of the glass, and is easily bent downward. When the upper frame is bent, the panel body may be forcibly peeled off from the panel frame, or the panel body may escape and curve inward and outward, and an uneven surface may be formed on the outer wall surface to ruin the design of the outer wall. Therefore, it is necessary to firmly configure the upper frame in advance in consideration of the inertial load of the glass due to the earthquake, and there is a problem that the entire panel frame becomes heavy. If the entire panel frame becomes heavier, it will affect the strength of the fasteners and cubicles that support it, and even the strength of the skeleton, as well as the construction.

The present invention has been made in view of such a problem, and provides a panel frame of a curtain wall panel unit which can maintain sufficient strength against a vertical load and can be made lightweight. That is the purpose.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention comprises a left and right vertical frame having an upper frame and a lower frame formed in a rectangular frame, and at least the upper frame is installed directly above the glass frame. In the panel frame of the curtain wall panel unit that also functions as a panel unit, a pair of positioning members is provided between the upper frame and each of the left and right vertical frames. It is characterized in that it is arranged at the position of the upper frame provided.

[0007]

By providing a pair of brackets between the upper frame and each of the left and right vertical frames, and disposing the end of the upper frame side of the bracket at a position of the upper frame where the glass setting block is provided. The load of the glass is transmitted from the setting block to the portion of the upper frame where the setting block is provided, and is dispersed here, via the upper frame which is supported by the vertical frame at both ends, and via a pair of holding members. And are supported by the left and right vertical frames. In this case, since each side and each vertical frame supports the upper frame immediately below the setting block, it is possible to effectively prevent the upper frame from bending and receive most of the load of the glass. Since each side and each vertical frame receive the load of the glass as a compressive load, the load of the glass can be sufficiently supported with a relatively small cross-sectional area.
