[0002] The expansion joint glass curtain wall is a special design in the glass curtain wall structure, which combines the characteristics of expansion joints and glass curtain walls. An expansion joint refers to a gap reserved in the building structure with a certain width, length, and depth. Its main function is to relieve the deformation of the building caused by natural forces such as earthquakes and wind pressures, and ensure the overall structural stability of the building. The glass curtain wall is a commonly used exterior wall decoration material in modern architecture, with characteristics such as beauty, daylighting, and heat preservation. The expansion joints between glass curtain walls need to be connected by connecting devices to ensure the stability and safety of the glass curtain wall at the expansion joints. There are still certain defects in the existing connecting devices during use.

[0003] In the prior art, there are few connecting devices for expansion joint glass curtain walls, resulting in easy damage to the connecting devices, which affects the sealing performance of the expansion joints. At the same time, it is also easy to cause damage to the glass curtain wall and affect the service life of the glass curtain wall. Content of the Utility Model

[0004] The purpose of the utility model is to provide a new type of expansion joint glass curtain wall connecting device to solve the problem that the existing connecting devices in the current market are easy to be damaged as mentioned in the above background technique.

A steel square pipe is arranged on the outer side of the aluminum alloy column. An aluminum alloy cross beam is installed between the aluminum alloy column and the steel square pipe. An expansion joint main body is arranged between the two steel square pipes. A glass curtain wall main body is jointly installed on the outer sides of the aluminum alloy column and the steel square pipe. An aluminum alloy decorative cover is installed on the outer side of the joint of the two glass curtain wall main bodies. A first bent aluminum plate is jointly installed between the two steel square pipes. A foam rod is installed between the first bent aluminum plate and the glass curtain wall main body. Thermal insulation rock wool is installed on the inner side of the first bent aluminum plate. Aluminum alloy angle codes are installed on one side of each of the two steel square pipes close to the expansion joint main body.

[0006] Preferably, a second bent aluminum plate is jointly installed between the two aluminum alloy angle codes, and connecting plates are welded on one side of each of the two steel square pipes close to the expansion joint main body.

[0007] Preferably, an ethylene propylene diene monomer (EPDM) rubber water stop is arranged between the two connecting plates, and butt plates are connected to both ends of the EPDM rubber water stop.

[0008] Preferably, bolts are connected through the internal threads of the docking plate, and two groups of bolts are symmetrically arranged about the center of the docking plate.

[0009] Preferably, the aluminum alloy angle code is L-shaped, and the central included angles of the first bent aluminum plate and the second bent aluminum plate are the same.

[0010] Preferably, the docking plate is made of stainless steel.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: For this new telescopic joint glass curtain wall connecting device, the first bent aluminum plate is jointly installed on the outer sides of two groups of steel square tubes, and thermal insulation rock wool is installed on the inner side of the first bent aluminum plate.

Then, the docking plates at both ends of the ethylene propylene diene monomer (EPDM) rubber water stop are closely attached to the surface of the connecting plate, and the bolts are tightened, so that the EPDM rubber water stop is located inside the telescopic joint main body. When the glass curtain wall main body undergoes telescopic deformation, the two groups of steel square tubes can squeeze or stretch the first bent aluminum plate and the second bent aluminum plate. At the same time, the EPDM rubber water stop can be bent or extended. At the same time, when the glass curtain wall main body is relatively stable, the first bent aluminum plate and the second bent aluminum plate can improve the stability of the position of the telescopic joint main body. The connection of the first bent aluminum plate, the second bent aluminum plate and the EPDM rubber water stop can improve the overall structural stability of the glass curtain wall main body, so as to cope with the expansion and contraction problems of the building caused by temperature changes, and the first bent aluminum plate, the second bent aluminum plate and the EPDM rubber water stop are not easily damaged.
