Description

Technical Field

[0001] This utility model relates to the technical field of curtain wall installation, and in particular to a transition connection node between the interlayer structure and the top of the curtain wall. Background Technology

[0002] Currently, there are large gaps between the upper and lower layers of some curtain walls. In order to ensure the aesthetics of the connection between different layers, the conventional practice is to install interlayer decorative panels between the layers.

[0003] Chinese utility model patent application number CN202222279062.3 discloses a curtain wall unit inter-layer connection system, including a main horizontal beam, a transfer beam, and a transition frame. The main horizontal beam is supported by corbels on its outer side, and the transition frame is connected to the outer side of the transfer beam. The transfer beam is connected to the vertical keel of the adjacent layer curtain wall unit through transition components, and decorative panels are installed on the outer side of the transition frame. In this utility model, the corbels support the transfer beam, and both the transition components and the transition frame are connected and fixed to the transfer beam, avoiding direct welding of each transition component to the connecting plate, thus preventing deformation of the main horizontal beam due to welding during curtain wall installation. The corbels on the outer side of the connecting plate support the transfer beam, requiring only a sufficient number of connecting plates to meet the structural strength of the transfer beam. Furthermore, since both the transition components and the transition frame are welded and fixed to the transfer beam, even if adjacent layer curtain wall units are misaligned, the vertical keels of different layers can be connected to different positions on the transfer beam through transition components, eliminating the need for additional connecting plates.

[0004] The above-mentioned solution discloses an interlayer treatment method. The biggest problem with this method is that it requires adding a large number of skeletons outside the structure, which is not conducive to on-site construction for high-altitude construction, and the construction cost is relatively high. Utility Model Content

The insulated glass is fixed to the vertical keels and horizontal keels respectively by aluminum alloy pressure plates.

[0013] In this utility model, the interlayer structure and the top transition connection node of the curtain wall are further provided with an isolation steel plate between the interlayer structure and the horizontal keel. One end of the isolation steel plate is connected to the interlayer structure and the other end is connected to the horizontal keel.

[0014] In this utility model, the interlayer structure and the top transition connection node of the curtain wall are further provided with a decorative buckle plate installed on the outside of the aluminum alloy pressure plate, and a sealant is provided between the decorative buckle plate and the bottom plate of the transition aluminum plate.

[0015] In this utility model, the interlayer structure and the top transition connection node of the curtain wall are further provided.
