Description

[Detailed Description of the Invention] The present invention relates to a joining fitting used for attaching panels, etc. to a curtain wall.

When constructing panels with a length equivalent to the floor height in the form of a curtain wall, it is necessary to reinforce a large cross section in the vertical direction, which increases its own weight, so the hanging hardware such as fasteners becomes large, and the length including the base (reinforcing material) is also increased. It had the disadvantage of increasing costs.

On the other hand, when changing from the curtain wall type to the spandrel solid type (where the panels are screwed to the steel frame), the installation work is difficult because tens of thousands of screws must be driven on site.

The conventional method will be explained with reference to FIGS. 1 and 2. One panel A is formed by bending a side wall B at a right angle.
The other panel A' is further provided with a connecting piece C parallel to the panel surface from a side wall B bent at a right angle. Then, reinforcing members D, . . . , which are groove-shaped with lips in the vertical direction at both ends of both panels A, A', are fixed to the side wall B, respectively, with screws E, . In addition, a key-shaped connecting member F is fixed by welding in the vertical direction to the reinforcing member E fixed to one panel A, and this connecting member F and the connecting piece C are fixed with screws G, . . . After connecting both panels A and A' and filling the connecting piece C with filler H, sealing material I is fitted between both panels A and A' to maintain airtightness and watertightness. I was getting used to it.

Since the conventional structure was as described above, the weight of the reinforcing member E was heavy, and a large hanging fitting such as a fastener was required. Furthermore, since it has the disadvantage of large deflection, and the distance between both panels A and A' is not always constant, a liner is interposed between panel A' and reinforcing member E so that it can be connected to connecting member F. There is a need. In addition, the connecting piece C and the connecting member F
It is necessary to secure the connection with screws on site. Therefore, a lot of on-site work was required, and it was not possible to deal with the shaking of the building, thermal expansion, contraction, etc.

In view of the above-mentioned drawbacks of the conventional technology, the present invention eliminates the need for screw fixing work on site, is lightweight, has less deflection, and can be moved when the building oscillates or thermally expands or contracts. can.
The object is to provide a joining fitting for panels in a curtain wall.

The structure of the present invention will be explained in detail based on the first embodiment shown in FIGS. 3 to 6. Panels A and A' are both bent at right angles to form side walls 1 and 1'. Fitting grooves 2, 2' recessed toward the center are provided on the entire surface of the end of the 1', and a male connector 3 is fixed to one of the grooves 2, and a female connector 4 is fixed to the other groove 2. to be fixed.

As shown in FIG. 6, the male connector 3 has a rectangular base 5 with convex protrusions 6 in the longitudinal direction except for both ends, and two through holes 7 at each end. are provided and fixed to the bottom wall of the fitting groove 2 with screws 8, .

As shown in FIG. 5, the female connector 4 has a rectangular base 9 with joint pieces 10, 10' protruding at intervals on both sides of the base 9 in the longitudinal direction except for both ends, and the inner surface is a sliding surface. A joint fitting groove 11 is provided, and two through holes 12, .

The male connector 3 and the female connector 4 configured as described above are fixed at two locations spaced apart from each other in the longitudinal direction (vertical direction) of panels A and A', respectively, and the protrusion 6 of the male connector 3 is fixed to the female connector. It is inserted into the joint fitting groove 11 of the joint tool 4 to connect both panels A and A'.

In addition, 13 and 13' in FIG. 4 are mounting members formed in an O-shape, respectively, and the male and female connectors 4 and 3 are inserted into the fitting grooves 2 and 3, respectively.
When fixing it to 2', fix it together with screw 8...
Then, the mounting members 13, 13' are fixed to the reinforcing bars 15 fixed to the frame 14 by welding.

In addition, in the figure, H is a filler material, and I is a sealing material.

This embodiment is constructed as described above, and the female and male connectors 3, 4 and mounting members 13, 13' are assembled at the factory.
are fixed with screws 8, .

Therefore, there is no need for screw fixing work at the site as in the conventional case. Therefore, the construction time is short. Also, 1 to 2 locations in the longitudinal direction.
Since it is only connected at certain points, it is light in weight and requires small hanging fittings such as fasteners.

Furthermore, even if an error occurs in the distance between the panels A and A', there is no need for a liner or the like for adjustment as in the conventional case.

In addition, even if the joint parts of panels A and A' change due to the shaking of the building, thermal expansion, contraction, etc., the female joint fitting 4 has a sliding surface in the joint fitting groove 11.
The protrusion 6 can be moved to cope with expansion and contraction due to thermal expansion and movement due to vibration.

Previously, panels with different bending dimensions were fitted together, so the bent shapes were different on the left and right sides of a single panel, but now the same shape can be used, greatly improving workability in the factory.

Furthermore, since the joint fitting groove 11 is also open on the longitudinal side, the connection work can be easily performed.

Note that since the panel is supported by two mounting members 13 and 13', the deflection of the panel is extremely small. It can also be supported at three or more locations if necessary.

Next, a second embodiment shown in FIG. 7 will be described. One panel A' is provided with a fitting groove 2 at the lower end of the side wall 1' as in FIG. 1. The side wall 1 of the other panel A is provided with an inclined surface 17, and the lower end of this inclined surface 17 is bent into an L shape.

The female joint fitting 4 is formed in a U-shape, and the joint fitting groove 1
The locking pieces 19, 19 are formed by bending the open ends of the side pieces 18, 18 forming the holder 1 inward at an acute angle. This female joint fitting 4 has a locking piece 19 in the fitting groove 2,
Fix with a plurality of screws 8, . . . so that 19 protrudes.

Further, the male connecting metal fitting 3 is formed into a U-shape smaller in width than the female connecting metal fitting 4, and the two side pieces 20, 20
The locking pieces 21, 21 are formed by bending the open end of the protrusion 6 outward at an acute angle. and,
Connect the male joint fitting 3 with the open end outward, together with the back plate 16 located on the back side of the side wall 1, and a plurality of screws 8,...
Fix it with...

The protrusion 6 of the male connector 3 is inserted into the joint fitting groove 11 of the female connector 4 to connect both panels A and A'.

In this embodiment, the locking pieces 19, 19 are firmly connected by the spring action of the locking pieces 19, 19, and after the connection, the locking pieces 19, 19 and 21, 21 prevent them from coming apart.

Next, referring to the third embodiment shown in FIG. 8, both panels A and A' are provided with short side walls 1 and 1'. Then, a male joint fitting 3 is attached to the back side of the side walls 1 and 1'.
and the female joint fitting 4 are each fixed with a plurality of screws 8, .

The male joint fitting 3 is formed into a groove shape, and has side pieces 20, 20 protruding at intervals on the opposite side to form a protrusion 6, and a protrusion 2 on the outside of the tips of the side pieces 20, 20.
2 and 22 are provided protrudingly.

The female joint fitting 4 is connected to the T from one end surface of the groove portion 23.
A joint fitting groove 11 is formed by protruding a member 24 having a letter shape.

Fitting the protrusion 6 into the joint fitting groove 11,
The spring action of the raised portions 22, 22 provides a strong connection.

Since the present device has the above-mentioned structure and function, it does not require screw fastening work as in the past on site, so construction time is short, and even if an error occurs in the spacing between the two panels A and A', no liners or the like are required for adjustment as in the past.

Furthermore, even if the joints of the panels A and A' change due to vibrations of the building, thermal expansion, contraction, etc., the changes can be sufficiently coped with by moving the protrusions.
