Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art In a panel unit for a curtain wall, a panel body such as a metal plate having a certain strength and design for forming an outer wall surface is riveted to a panel frame which maintains the rigidity of the panel body. It is configured by joining with an adhesive or the like. The panel frame supports the panel body so as to sufficiently withstand wind pressure, and conventionally, is generally configured by arranging an upper frame and a lower frame in a rectangular shape on left and right vertical frames.

On the other hand, in a unit type curtain wall or the like which does not use any eyes, a panel unit is used as a waist plate on each floor, and the panel unit and glass are alternately arranged in the vertical direction to form an outer wall surface. In this case, the upper frame and the lower frame of the panel unit also serve as the lower frame of the glass positioned directly above and the upper frame of the glass positioned directly below. In this case, the glass is supported on the upper frame of the panel unit, that is, the pair of left and right setting blocks provided in the dovetail groove of the upper frame of the panel frame, similarly to the case where the glass is mounted on the panel. It is fitted into the frame.

[0004]

In the panel frame of the conventional curtain wall panel unit as described above, the weight of the glass positioned immediately above is received by the upper frame via the left and right setting blocks, and the upper frame is received. It is designed to be transmitted from the upper frame to the left and right vertical frames with both ends. Therefore, the upper frame receives a bending load due to the weight of the glass and is easily bent downward. When the upper frame bends, the panel body may be forced and peeled off from the panel frame, or the panel body may escape inward and outward and bend, resulting in an uneven surface on the outer wall surface and ruining the design of the outer wall. Therefore, it is necessary to strongly configure the upper frame in advance in consideration of the inertial load of the glass due to the earthquake, which causes a problem that the entire panel frame becomes heavy. If the whole panel frame becomes heavy, it will affect not only the strength of the fasteners and cubes that support it, but also the strength of the skeleton and also the construction.

The present invention has been made in view of the above problems, and provides a panel frame of a panel unit for a curtain wall, which can maintain sufficient strength against a load in the vertical direction and can be constructed in a light weight. That is the purpose.

[0006]

In order to achieve the above object, the present invention comprises a glass frame in which an upper frame and a lower frame are squarely framed on the left and right vertical frames, and at least the upper frame is incorporated directly above. In the panel frame of the panel unit for the curtain wall, which also serves as a panel unit, a pair of barbs that are passed between the upper frame and the left and right vertical frames are provided. It is characterized in that it is arranged at a portion of an upper frame provided.

[0007]

By providing a pair of canes between the upper frame and each of the left and right vertical frames, and disposing the upper frame side end of the canes at the upper frame portion where the glass setting block is provided. , The load of the glass is transmitted from the setting block to the part of the upper frame where the setting block is provided, and it is dispersed here and is supported by the vertical frame with both ends supported by a pair of jaws. It is supported by the left and right vertical frames. In this case, since each direction and each vertical frame support the upper frame immediately below the setting block, it is possible to effectively prevent the upper frame from bending and receive most of the glass load. And since each direction and each vertical frame receive the load of glass as a compressive load, the load of glass can be fully supported with a comparatively small cross-sectional area.
