Description

Technical Field

[0001] This invention relates to the field of non-normal disordered faceted glass curtain wall technology, and in particular to a suspended mesh shell steel frame diamond-cut glass curtain wall structure. Background Technology

[0002] In architecture, once the main structure and building height are fixed, the building envelope becomes the focus of energy conservation. Glass curtain walls are a widely used, novel, and aesthetically pleasing form of building wall decoration. Modern curtain walls are increasingly becoming an integral part of the overall building, participating in the functional construction of the entire building. Environmental protection, energy conservation, and the pursuit of aesthetics and personalization are the development directions of curtain walls.

[0003] 1. For example, Chinese patent discloses a suspended glass curtain wall (publication number: CN115538668A), which includes multiple horizontal beams, each with multiple suspension components at equal intervals, forming multiple square suspension areas, each containing a glass curtain wall panel. The suspension components include cross-shaped suspension heads, threaded connections, and fixing heads. The outer end of the cross-shaped suspension head has a blocking part. The four corners of the glass curtain wall panel are respectively installed in the mounting slots of the four cross-shaped suspension heads. The fixing head is inserted into a hole, its end protruding and locked by a locking mechanism. The threaded connection has a first nut and a second nut threadedly connected, with a pressure spring between the first nut and the second nut. The suspension components and glass curtain wall panels cannot loosen, thus possessing extremely high stability. The glass curtain wall panels are placed directly on the baffles of the suspension components, eliminating the need for drilling for support, resulting in higher inherent strength. Maintenance is not required through external high-altitude operations, making replacement quick, convenient, and highly safe.

[0004] 2. A suspended glass curtain wall for high-rise irregular-shaped buildings (Publication No.: CN217871216U) includes a first mounting frame, a first mounting groove inside the first mounting frame, and a plurality of first threaded holes on the surface of the first mounting frame outside the first mounting groove. A first rubber pad is fixedly connected inside the first mounting groove, and a glass curtain wall body is mounted on the surface of the first rubber pad. A second mounting frame is mounted on the surface of the first mounting frame, a second mounting groove inside the second mounting frame, and a plurality of second threaded holes on the surface of the second mounting frame outside the second mounting groove. A second rubber pad is fixedly connected inside the second mounting groove. A plurality of first suspension rods are fixedly connected to the top of the first mounting frame, and a first mounting plate is fixedly connected to the end of each of the plurality of first suspension rods. A plurality of second suspension rods are fixedly connected to the bottom of the first mounting frame. The design of the first mounting frame, the second mounting frame, and the plurality of first and second threaded holes facilitates the rapid installation of the glass curtain wall.

[0005] As architectural designs continue to evolve towards novelty and individuality, curtain wall engineering structures and materials have become increasingly diverse and complex in order to match architectural forms, with varied and complex stress patterns and different material shapes.

[0006] Therefore, it is necessary to propose a suspended grid shell steel frame diamond-cut glass curtain wall structure to address the above problems. Summary of the Invention

[0044] Working principle:

[0045] The steel beam structure 1 is installed on the main structure 10. The main keel frame and the secondary keel frame are pre-assembled on the ground. The first glass curtain wall component 5 and the second glass curtain wall component 6 are assembled between the main keel frame and the secondary keel frame respectively. The first glass curtain wall component 5 is hoisted up and fixed to the steel beam structure 1 by the lower support 2. The second glass curtain wall component 6 is hoisted up and connected to the main keel 8 at the bottom of the first glass curtain wall component 5 by the support 3 and the connecting steel parts 4. Then the glass curtain wall components are installed.
