Description
Technical Field
[0001] This utility model relates to the field of building decorative curtain wall technology, and in particular to a structurally stable building decorative curtain wall structure. Background Technology
[0002] Architectural decorative curtain walls are composed of a supporting structural system and panels. They are building envelopes or decorative structures that can have a certain displacement capacity relative to the main structure and do not share the load and action of the main structure. They are hung up like a curtain and are lightweight wall materials with decorative effects commonly used in modern large and high-rise buildings.
[0003] The existing utility model patent with publication number CN218562692U discloses a building exterior decorative curtain wall. It states that "when wind blows onto the surface of the decorative aluminum panel, the airflow can move upwards under the guidance of the inclined side of the triangular cover and exit through the air inlet, improving the wind resistance of the decorative aluminum panel during use. Furthermore, rainwater falling on the inclined side of the triangular cover is guided by the inclined side, preventing rainwater from wetting the installation cage and improving the protection of the installation cage." While this solves the problem that "closed aluminum panels cannot guide wind during use, resulting in greater pressure on the decorative aluminum panel when wind blows onto it, and the mesh structure has poor rainwater blocking effect, leading to rainwater wetting the installation cage and accelerating its corrosion," traditional curtain wall installation often requires a large number of bolts or welding for fixing, which is cumbersome and difficult to disassemble during later maintenance. Moreover, it is prone to loosening under long-term vibration or load, leading to decreased curtain wall stability and safety hazards. Therefore, a structurally stable building decorative curtain wall structure is proposed. Utility Model Content
[0004] Therefore, it is necessary to provide a structurally stable building decoration curtain wall structure to address the aforementioned technical problems.
[0005] In order to solve the above-mentioned technical problems, this utility model solves the problem that traditional curtain wall installation often requires a large number of bolts or welding for fixing, the process is cumbersome, and it is easy to loosen under long-term vibration or load.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] As a preferred embodiment of the structurally stable building decorative curtain wall structure provided by this utility model, the top of the limiting plate is provided with a slot, and one side of the positioning sleeve is provided with an anti-loosening frame.
[0012] As a preferred embodiment of the structurally stable building decorative curtain wall structure provided by this utility model, the inner cavity of the slot is engaged with a plug, and the top of the plug is fixedly connected to a portion of the anti-loosening frame on the same side.
[0013] As a preferred embodiment of the structurally stable building decorative curtain wall structure provided by this utility model, the wall mounting component includes two fixing plates fixed to the wall, and the front of the fixing plate is provided with a groove.
[0014] As a preferred embodiment of the structurally stable building decorative curtain wall structure provided by this utility model, two fixing plates are fixedly connected to the middle of the back of the keel frame, and a threaded rod is fixedly connected to the top of the fixing plate.
[0015] As a preferred embodiment of the structurally stable building decorative curtain wall structure provided by this utility model, the top end of the threaded rod 2 moves through the inner cavity of the groove and is threadedly connected to a fixing nut.
[0016] As a preferred embodiment of the structurally stable building decorative curtain wall structure provided by this utility model, one side of the limiting plate extends to the back side of the keel frame, and one end face of the positioning sleeve abuts against the other side of the limiting plate.
[0017] As a preferred embodiment of the structurally stable building decorative curtain wall structure provided by this utility model, the fixing plate is L-shaped and symmetrically distributed.
[0018] As a preferred embodiment of the structurally stable building decorative curtain wall structure provided by this utility model, the anti-loosening frame is in the shape of an "L", with one part placed on the rear side of the positioning sleeve and the other part placed on the top of the limiting plate.
[0019] Compared with the prior art, the present invention has the following beneficial effects:
[0020] This utility model provides a structurally stable building decorative curtain wall structure. By allowing the connecting block on the back of the curtain wall to slide directly through the mounting hole of the keel frame, the limiting plate is rotated to the back of the keel frame. Then, the positioning sleeve is tightened against the limiting plate by the threaded rod, thus completing the fixation of the curtain wall and the keel frame. The anti-loosening bracket is then installed at the connection between the positioning sleeve and the limiting plate using the slot on the limiting plate, thereby preventing the positioning sleeve from loosening backward due to vibration or other factors.
[0021] This utility model provides a structurally stable building decorative curtain wall structure. By designing grooves, the distance between the keel frame and the wall can be adjusted as needed when the keel frame is installed on the wall. This effectively compensates for wall construction errors or meets the requirements of different building designs for the curtain wall cantilever distance, thus improving the flexibility and adaptability of curtain wall installation.
