[0002]

2. Description of the Related Art With the modernization of urbanization, there is an increasing demand for curtain walls. In recent years, there has been an increasing interest in designs in which the frames holding the panels are not conspicuous, and when viewed as a whole, the panels appear to be continuous only by leaving joints between adjacent panels.

To meet this demand, Japanese Patent Laid-Open No.
39691 (Prior art 1) and JP-A-4-293
A prior example such as Japanese Patent No. 884 (Prior Art 2) can be given. In the preceding example 1, a lower supporting member having a diagonal cut surface at a peripheral portion is locked and attached to a frame, and then a rain barrier (sealing material) and a setting block are interposed on the lower supporting member to form a glass. Is described, and then the glass is attached to the upper side of the glass by engaging an upper support via a rain barrier. Further, the prior art 2 discloses a method in which glass is fixed in advance as a glass unit by an annular frame, and the glass unit is fixed to a support member on the building side.

[0004]

However, when assembling the glass support material and the glass sequentially with respect to the frame as in the first prior art, the number of members increases, so that it is troublesome to assemble at the site. Will be hung.
Further, since the support member and the frame are formed of different members, there is a problem that it is difficult to ensure perfect watertightness.

Further, in the case of the preceding example 2, even if the mounting is facilitated by the unitized structure, the supporting member and the glass unit are fixed by a connecting member connecting the four peripheral portions. Eventually, installation of the connecting member takes time. In addition, the external force acting on the glass is a load-bearing structure that is transmitted to the annular frame, the connecting attachment member, and the support member in order, and the stability of the force transmission structure is low due to the complexity of the external force such as an earthquake due to the complexity. I have.

Accordingly, the main problems of the present invention are that the panel support structure is simple and the workability is good, that the panel can be firmly supported under various loads, and that the water tightness is good. It is to provide a curtain wall panel unit satisfying the following.

[0007]

The object of the present invention is to provide a curtain wall panel unit which is mounted on a panel mounting bracket fixed to a skeleton side via a cubicle,

Panel locking pieces for supporting the panel upper and lower sides and one side are integrally formed on one of the outdoor surfaces of the upper and lower frames and the left and right vertical frames, respectively, and the upper and lower sides of the panel and the one side are formed. After fitting the part into the panel locking piece and attaching it,
In the other side of the panel, a side panel supporting member on which a panel locking piece is formed is connected to the other of the left and right vertical frames to support the other side of the panel. it can.

In this case, a horizontal frame may be provided in the frame, and one unit may be composed of a plurality of panels. In addition, in the panel locking piece on the upper side of the panel, a margin space for a lifting margin is formed in the panel fitting groove formed by the panel locking piece in order to fit the panel in a thorough manner. This facilitates the fitting of the panel.
Furthermore, by chamfering the outdoor portion of the panel periphery and making the inner surface of the panel locking piece an inclined surface corresponding to the chamfering of the panel, the panel and the panel locking piece have the same outdoor surface. Thus, it is possible to provide a panel unit for a curtain wall of an overall flat type corresponding to recent design trends.

[0009] Further, around the indoor surface side of the panel, the gap between the panel and the frame is filled with a hardening type sealing material for adhesively fixing the panel or a solid elastic material is press-fitted to strengthen the panel. To support.

[0010]

In the present invention, a panel locking piece is formed integrally with one of the upper and lower frames and the left and right vertical frames, and the panel is supported by the integrally formed panel locking piece. Therefore, as compared with the case where the panel is supported with a separate support member interposed therebetween, the structure is simplified, the workability is improved, and the airtightness is improved. In addition, since the panel is supported by the locking pieces integrally formed on the frame, the rigidity of the entire unit is high, and even when an external force such as an earthquake or wind is applied, the force is directly transmitted to the frame, particularly By filling the gap between the frame and the frame around the back of the panel with an adhesive seal or by press-fitting a solid elastic material such as synthetic rubber, the frame unit is firmly supported and increases in-plane rigidity, further increasing wind pressure. External force is evenly distributed even when received. Also, since the panel inclined surface and the panel locking piece are engaged at the panel peripheral edge, the panel does not separate from the frame frame against negative wind pressure or earthquake,
The stability against external force is also greatly improved. Since the mounting position adjusting portion is provided on the back surface side of the frame unit, the position can be easily adjusted at this position by the push bolt and the pull bolt which are locked to the mounting position adjusting portion.
