Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the exterior of a building, and particularly to a structure for fixing panels between mullions arranged vertically on the exterior wall of a building. The term "panel" as used in the text includes transparent and opaque panels, sash, etc.

This type of structure has been known in the past, for example, by vertically arranging mullions with shaped cross sections at appropriate intervals on the exterior wall of the building, and installing elastic tight material on the interior wall of the outdoor flange. Also, a ridge or the like is attached to the indoor flange, and the panel is held between the tight material and the ridge. However, in the above-mentioned conventional structure, the rim is simply attached to the flange of the mullion, and the force that presses the panel to the tight material does not act, so sufficient watertightness between the tight material of the building and the panel cannot be achieved. There were drawbacks such as the complicated work required to attach the rim to the flange on the indoor side since a large number of bolts, screws, etc. were required.

The present invention was developed in consideration of the above, and uses wedge-shaped fixing fittings instead of the ridges of the conventional structure to pressure-bond the panel to the tight material, and uses a large number of bolts and
It provides a complete watertight structure between the tight material and the panel without using screws or the like.

Embodiments of the present invention shown in the accompanying drawings will be described below. 1 is a mullion with a shaped cross section, 2
and 3 are flanges on the outdoor side and the indoor side, respectively. An elastic gasket 4 is attached to the outdoor side flange 2 from the outdoor side. This gasket 4 also covers the inner wall surface of the outdoor side flange 2, and is provided with a tip portion 4a and a groove portion 4b. The above-mentioned tip portion and groove portion are useful for attaching the external mullion cover 5 to the portion of the mullion that protrudes toward the outdoor side.

Notches 6 are formed along the length of both end edges of the indoor flange 3 of the mullion. It is preferable that the length of the notch 6 is slightly longer than that of the fixing fitting described later. Reference numeral 7 denotes a panel to be held between the mullions, and both end edges 7a of the panel 7 are made of bent plate material so as to withstand the compressive load when the panel is fixed. Note that the width of the panel 7 is smaller than the inner width of the shaped cross section of the mullion 1.

Reference numeral 8 denotes a fixing metal fitting having a square cross section, and wedge-shaped engagement grooves 10, 10 are formed at the lower ends of opposite side sides 9, 9 of the U-shaped channel, and extend outward from the free end of the channel. Extruded flange part 11,1
1 will be provided. The engagement grooves 10, 10 are formed in a triangular shape with a vertical side on the indoor side and a downwardly inclined oblique side on the outdoor side, and open at the bottom.

When fixing the panel to the mullion, panel 7
The end edge 7a of the fitting 8 is brought into contact with the elastic gasket 4 mounted on the inner wall of the outdoor flange 2, and the fixing fitting 8 is
is inserted through the notch 6 of the indoor flange 3 in the direction of the solid arrow in FIG. 2, and then pushed down in the direction of the dotted arrow to insert the flange 1
1 is brought into contact with the indoor side surface of the edge portion 7a of the panel 7. When the fixture 8 is further pushed down, the panel 7 is pressed against the repulsive force of the gasket 4 to the outdoor side. The fixture 8 is fixed to the panel 7 with small screws 12 to prevent the fixture 8 from moving. Further, internal mullion covers 13, 13 are fitted onto the fixing fittings 8 to cover the indoor side protruding portion of the mullion 1.

In the above embodiment, a pair of wedge-shaped engagement grooves were provided in the fixing metal fitting, but in order to perform the wedge action, only the wedge-shaped part on the panel side of the fixing metal fitting is required, and the wedge-shaped parts can be formed in pairs. It is not necessary.

Since the present invention is constructed as described above, by inserting the fixing metal fittings into the notch of the mullion and pushing down, the panel is firmly pressed against the gasket by a wedge action, thereby ensuring sufficient watertightness between the gasket and the panel. Therefore, there is no need for a large number of bolts, screws, etc. for attaching the rim as in the conventional structure. Furthermore, as shown in the embodiment of the present invention, it has many effects such as being able to simultaneously fix panels located on both sides of the mullion.
