Close the gap between the vertical frames 11 and 12.

As described above, in this panel body, since the outdoor side of the panels 2a and 2b is held by the gasket 3 attached to the inner peripheral side surface of the frame 1, the found size of the frame 1 seen from the outdoor side can be reduced. The design is good, and the workability when mounting the panels 2a and 2b is also good. The frame 1 has a groove 4 on the inner peripheral side surface and a locking portion 5 provided on the indoor side of the groove 4, and the gasket 3 fits the fitting portion 6 into the groove 4 of the frame 1. At the same time, the locked portion 7 is locked to the locking portion 5 and attached to the inner peripheral side surface of the frame 1, and the lip portion 8 is crimped to the outdoor surface of the panels 2a and 2b, so that the panels 2a and 2b The gaskets 3 can stably hold the panels 2a and 2b even if a negative pressure acts on them. On the other hand, when a positive pressure acts on the panels 2a and 2b, the panels 2a and 2b try to separate from the gasket 3, but the lip portion 8 of the gasket 3 is on the panel 2a and 2b side (indoor side) of the panel contact surface 59. ), Since it is inclined toward the inner circumference side, it deforms following the movement of the panels 2a and 2b, and the action of pressing the panels 2a and 2b works. Therefore, even if a positive pressure acts on the panels 2a and 2b. The panels 2a and 2b can be stably held, and the ingress of water can be prevented.
Further, since the cross-sectional shape of the gasket 3 is triangular, there are effects such as draining due to the inclined surface of the gasket 3, an effect that the gasket 3 is inconspicuous in appearance, and a material cost of the gasket 3 is suppressed and there is no waste.
Further, in this panel body, since the groove 4 of the frame 1 and the locking portion 5 are on the outer peripheral side of the end faces of the panels 2a and 2b, it is easy to attach the panels 2a and 2b to the frame 1.
Since the found size of the frame 1 can be reduced in this panel body, the design can be improved and the material cost can be reduced. By making the gasket 3 black and the frame 1 silver, it is possible to realize a neat design in which the gasket 3 is inconspicuous. In this panel body, since the aluminum (frame 1) is not covered with the glass (panels 2a and 2b), the gasket 3 does not need to be enlarged.

Further, in this panel body, the catch pan 10 is arranged so as to be fitted between the vertical frames 11 and 12 of the lower left and right panel units 9 and 9, and the vertical frames 11 of the upper left and right panel units 9 and 9 are arranged. , 12 is in pressure contact with the upper surface 53 of the catch pan 10, so that it is easy to ensure the watertightness of the joint portion between the panel units 9, 9, 9, 9. That is, in this panel body, instead of attaching catch pans to four corners of the panel unit by adhesive or the like, they are fitted between the vertical frames 11 and 12 of the lower panel units 9 and 9. Only one catch pan 10 needs to be arranged, the workability is remarkably improved, and by using a single catch pan 10, there is no concern about water leakage from the gap between the conventional catch pans, so that it is watertight. Sex also improves.
The catch pan 10 can be easily positioned by arranging the catch pan 10 by fitting it into the fitting portion 48 formed by the male portion 43 and the female portion 45 of the vertical frames 11 and 12 of the lower panel units 9 and 9. ..

The present invention is not limited to the embodiments described above. The structure of the frame and the material of the panel do not matter. The shape of the groove with the frame and the locking portion, and the shape and material of the gasket can be changed as appropriate. The present invention can be widely used not only for curtain walls but also for all panel bodies in which a panel is held and attached to a frame with a gasket.
