Description

Technical Field

[0001] The utility model relates to the technical field of curtain wall crossbeams, in particular to a curtain wall crossbeam connection structure. Background Art

[0002] Glass curtain wall refers to the building's external protective structure or decorative structure that has a certain displacement capability relative to the main structure and does not share the effects on the main structure. The glass curtain wall is mainly composed of aluminum alloy columns, beams, beam buckle covers and glass. The columns and beams are fixed by aluminum alloy angle brackets and stainless steel bolts. To avoid the exposed bolts affecting the appearance, the angle brackets and bolts are inside the beams. The beams must be open beams for installation. However, open beams have openings that reduce the structural strength. To ensure the structural strength, the cross-section of the stroke cannot be very small, thereby increasing the installation cost. In addition, the columns and beams are connected by angle brackets, and the weight of the glass is borne by the beams. The aluminum alloy beams will have large distortions, which will affect the indoor visual effect.

[0003] According to Chinese patent number CN210947331U, a curtain wall beam connection structure is provided, including a column, a closed beam, a core sleeve and a spring pin, the closed beam is a hollow aluminum profile, a pin hole is arranged on the column, the cross section of the closed beam is a closed loop structure, the core sleeve is fixed to the inner side of the end of the closed beam, the core sleeve is provided with a mounting hole coaxial with the pin hole, the diameter of the mounting hole is larger than the diameter of the pin hole, the spring pin includes a plug, a pin column and a compression spring, which are arranged in the mounting hole of the core sleeve, the plug is fixed to the end of the mounting hole away from the pin hole, the compression spring is arranged in the middle of the mounting hole, the pin column can be slidably arranged at the end of the mounting hole close to the pin hole, the pin column includes a sliding part with the same diameter as the mounting hole and a pin connection part with the same diameter as the pin hole, the sliding part and the compression spring are arranged in the mounting hole of the core sleeve One end of the compression spring is abutted, and the pin connection part is passed through the pin hole to fix the closed beam to the column. The structural strength of the closed beam is higher and the cost of aluminum profiles is reduced. The closed beam is not easy to twist, and the connection between the closed beam and the column does not require an angle code. The core sleeve and the spring pin are hidden in the closed beam, which improves the visual effect, but the spring pin still needs to be installed in the closed beam through the core sleeve, and the core sleeve is installed in the closed beam through screws. When installing the closed beam, the spring pin needs to be installed on the core sleeve first, and then the core sleeve is installed in the closed beam. The installation steps are more complicated. In addition, the plug is connected to the pin column through the compression spring. In this way, when installing the spring pin, it is difficult to rotate the plug to thread the mounting hole of the core sleeve after the plug is inserted into the mounting hole, which is not convenient for installation and use.
