Description
Technical Field
[0001] This utility model relates to the technical field of building curtain walls, and in particular to a transition node between aluminum alloy louvers and glass curtain walls. Background Technology
[0002] A glass curtain wall (reflection glass curtain wall) refers to an exterior building envelope or decorative structure that is supported by a structural system and allows for a certain degree of displacement relative to the main structure, without sharing the loads of the main structure. The wall can be single-pane or double-pane glass. Glass curtain walls are an aesthetically pleasing and innovative method of architectural wall decoration, and a prominent feature of the modernist high-rise building era.
[0003] With the development of modern cities, building curtain walls have experienced rapid growth. Due to their advantages such as light weight, strong adaptability to building functions, fast and convenient construction, easy maintenance and replacement, and beautiful and transparent appearance, they are widely used in high-rise buildings such as office buildings and hotels, as well as large-span buildings such as shopping malls, convention centers, railway stations, and airport terminals.
[0004] To meet ventilation requirements, glass curtain walls often incorporate louvers or grille systems. Chinese utility model patent application CN202421143301.5 discloses a glass curtain wall structure system and architecture with embedded grilles. This system includes a glass curtain wall and grille components. The glass curtain wall has windows, and the grille components are embedded within the windows. The grille components include a grille frame, grilles, and a sub-frame structure. The grille frame is a frame structure adapted to the window. Multiple grilles are arranged at intervals within the grille frame. The sub-frame structure is located inside the grille frame, and the grille frame is connected to the window through the sub-frame structure. This utility model eliminates the traditional heavy frame, and the sub-frame structure is located inside the grille frame, hidden within the window, forming an embedded structure. This results in a smooth overall appearance of the glass curtain wall, and the grille components lack a heavy frame structure, making it simple, beautiful, and elegant.
[0005] The above installation scheme is an embedded installation, which is only suitable for installation on frameless glass curtain walls. It cannot be applied to exposed frame glass curtain walls due to its embedded installation. Furthermore, the existing louvers and glass curtain walls have issues with an unnatural transition and poor aesthetics. Utility Model Content

[0011] In this utility model, the aluminum alloy louver and glass curtain wall conversion node is further characterized by the inner and outer frame frames being L-shaped and formed on the louver.
[0012] In this utility model, the aluminum alloy louver and glass curtain wall conversion node is further described as follows: the connector is L-shaped, with one end connected to the window frame by screws and the other end connected to the aluminum alloy base by screws.
[0013] Furthermore, in this utility model, a heat-insulating strip is provided between the connecting part and the aluminum alloy pressure plate in the aluminum alloy louver and glass curtain wall conversion node.
[0014] In this utility model, the aluminum alloy louver and glass curtain wall conversion node is further provided with a groove formed on the connecting part and a protrusion formed on the thermal break strip that matches the shape of the groove.
