Description

Technical Field

[0001] This utility model relates to the field of curtain wall technology, and in particular to a steel-aluminum composite unit curtain wall structure. Background Technology

[0002] Currently, unitized curtain walls are mainly installed using a male-female column interlocking method. This installation method and the characteristics of aluminum alloy materials require that the unit panels be flat to ensure smooth connection during hoisting. For aesthetic purposes, cantilever components are often added to the male and female columns, achieved by covering them with aluminum or stainless steel plates¹¹ to create a protruding surface effect. However, while this construction method can achieve a localized protruding effect, it is difficult to achieve a concave surface effect or maintain the overall visual continuity of the panels. Therefore, a new curtain wall construction form is needed that combines the visual impact of the recessed unit design with the overall structural safety of the recessed unit curtain wall, ensuring waterproof sealing and preventing leakage, while also facilitating material processing and on-site installation.

[0021] To make the technical means, creative features, objectives and effects of this utility model easy to understand, the following embodiments, in conjunction with the accompanying drawings, will specifically illustrate the technical solution of this utility model.

[0022] See Figure 6 This embodiment provides a steel-aluminum composite unit curtain wall structure, which includes a steel frame 1, a glass unit 2, a subframe unit 3, and an aluminum alloy bottom beam 4.

[0023] See Figure 1 The steel frame 1 is composed of two steel plates 11 and several steel pipes, forming a U-shaped groove. The steel plates 11 are U-shaped flat plates, laser-cut from 16mm thick steel plates. The two steel plates 11 are symmetrically arranged, and several steel pipes connect them. These pipes include transverse rectangular steel pipes and oblique rectangular steel pipes. The transverse rectangular steel pipes come in two specifications: 40*40*4mm rectangular steel pipe 121 and 160*80*5mm rectangular steel pipe 122. The oblique rectangular steel pipe 123 uses 40*40*4mm rectangular steel pipe.

[0024] See Figure 1 , Figure 3 and Figure 4 The lower ends 111 of both steel plates 11 are configured as downward extending structures, and steel plate bolt holes are opened on them.

[0025] See Figure 2 and Figure 3 Glass unit 2 includes an aluminum frame 21 and a glass panel 22 fitted and installed within the aluminum frame 21. The aluminum frame 21 includes two columns and an upper beam and a lower beam welded to the two columns. The upper ends 211 of the two columns protrude from the upper surface of the upper beam, and the protruding portions of the columns have bolt holes for the aluminum frame. See also... Figure 4 The bolt holes in the steel plate and the bolt holes in the aluminum frame are connected and fixed by bolts 7, so that the glass unit 2 is connected and fixed below the steel frame 1.

[0026] See Figure 5The subframe unit 3 includes an aluminum alloy subframe 31 and a metal plate 32 connected and fixed to the aluminum alloy subframe 31. The metal plate 32 can be made of aluminum or other metal plates according to the actual needs of the curtain wall. The aluminum alloy subframe 31 and the metal plate 32 are riveted and fixed together by rivets 33. The subframe unit 3 has a U-shaped groove structure. The subframe unit 3 is installed as a whole in the U-shaped groove of the steel frame 1, and the aluminum alloy subframe 31 is connected and fixed to the steel plate 11 in the steel frame 1 by bolts.

[0027] See Figure 6 A sealing strip 5 is installed at the gap between the aluminum alloy subframe 31 and the glass unit 2. In this embodiment, two sealing strips are installed. The sealing strips, together with the dust-tight sealing strip of the glass unit 2, form a waterproof closed loop for the curtain wall unit.

[0028] The aluminum alloy support beam 4 is bolted to the top of the steel frame 1. The support beam of the curtain wall unit is the key point for the installation and positioning of this entire unit curtain wall, and is used to ensure the correct installation position of the curtain wall unit during curtain wall construction.

[0029] See Figure 3 Metal connectors 61 and 62 are also installed and fixed on the steel plate 11 of the steel frame 1 by bolts. The installation of such metal connectors allows the steel frame 1 to be connected and fixed to other structures of the entire curtain wall project.

[0030] In curtain wall construction, such as Figure 6 After the steel-aluminum composite unit curtain wall structure shown is installed, the metal-faced rock wool sandwich panels and back panels between the curtain wall layers are installed accordingly. The installation method adopts the existing conventional method. At this point, the construction forms a complete curtain wall unit panel.

[0031] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model are included within the scope of protection of this utility model.
