Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a butt connection structure for members, and more particularly to a butt connection structure for metal shapes used in building structures, for example.

In the conventional seamless butt connection structure, the opposing edges of the two shapes to be connected are cut diagonally according to the connection angle and brought into contact and welded. In the case of aluminum, special techniques were required for welding.

In addition, as shown in Figs. 1A and 1B, there is a device in which a bent connecting block 2 is inserted into the abutting portion of the shapes 1 and 1', but the bending angle of the connecting block must be changed depending on the connection angle. Therefore, it was not possible to adapt to various design angles.

As a further structure, as shown in FIGS. 2A and 2B, a groove is formed in advance inside the mold by taking advantage of the extruded bottom shape, and a bent plate-shaped connecting fitting 3 is inserted into the groove to connect it. There is something.

This structure is superior to the two structures mentioned above because it can accommodate various design angles, but it is wasteful to provide grooves that are necessary only at the connection part over the entire part of the part, and there is also a back-up for sealing at the butting edge of the part. Since there was no club, the rain event was not complete.

The present invention overcomes the above-mentioned drawbacks of the conventional structure.

Figures 3 to 5 show an embodiment of the present invention taking a corner glass abutting part as an example, 11.11' and 12.12'.
' is the shape material and the connection fitting receiving member to be butt-connected, and the respective butt edges are cut at an angle corresponding to the required connection angle.

In the embodiment of FIG. 3, the connection angle is 90' and the cutting angle of the profile and the connection fitting receiving member is 45°.

Reference numeral 13 denotes a connection groove formed inside the connection fitting receiving member 12.12', and a protrusion (not shown) of a slight height is formed inside the groove.

14. Reference numeral 14 denotes a connecting fitting made of a steel plate, and in this embodiment, its bending angle is 90°.

During assembly, the connecting fitting 14.14 is press-fitted into the connecting groove 13 from the abutting edge side of the connecting fitting receiving member 12.12' until the end edge of the member 12.12' comes into contact.

Next, fit and insert the connection fitting receiving member 12.12' into the molded material 11.11' fixed to the mullions 15, 15'.
．． The gap W between the abutting edges of 12' is maintained at about 1Qmm, and the mold material and the connection fitting receiving member are fixed with screws or knock pins.

Finally, the gap W is sealed.

Note that 16 indicates the glass installed on the upper floor.

Since the present invention is constructed in this way, it is possible to accommodate various connection angles by simply cutting the butting edges of the shape material and the connecting metal fitting receiving member diagonally and by changing the bending angle of the connecting metal fitting. There is no need for complicated shaping of the connecting groove, and since the connecting fitting member also serves as a back-up material as shown in FIG. 3, the seal for rain protection is perfect.
