Description

TECHNICAL FIELD

[0001] The present application belongs to the field of glass curtain wall, and particularly relates to a glass curtain wall installation structure and method for steel members passing through. BACKGROUND

[0002] In large public buildings such as exhibition halls, airports, and sports venues, the combination of steel structures and glass curtain walls is increasingly widespread. Such buildings often use large-span spatial tube truss structures. In order to achieve an open view and a transparent indoor space, some steel members extend to the building boundary and pass through the glass curtain wall.

[0003] In actual engineering, due to factors such as factory machining precision, on-site welding deformation, temperature changes, and installation measurement errors, there is inevitably a certain allowable deviation in the installation of steel structures. When steel members need to pass through a curtain wall system with extremely high precision requirements, these millimeter-level or even centimeter-level deviations can cause a series of problems: 1) Non-standardized nodes: The intersection points of each truss and the curtain wall are not exactly the same, so it is not possible to use a unified standard node component. A large number of "tailor-made" special-shaped parts are needed, increasing the complexity and cost of design, processing, and construction.

[0004] 2) Installation difficulty: Precast standardized curtain wall panels cannot be directly and accurately connected to steel structures with different positions, making installation difficult. Even on-site cutting and adjustment of curtain wall panels are required, which can damage their integrity.

[0005] 3) Difficulty in ensuring sealing performance: Irregular intersection gaps are difficult to effectively and reliably seal, and there is a risk of water and air leakage and a decrease in sound insulation performance.

[0006] 4) Stress concentration: Hard connections can cause excessive stress concentration in the curtain wall glass or keel when the steel structure is slightly deformed, posing a safety hazard.

[0007] Therefore, there is an urgent need for a solution that can effectively absorb and adapt to steel structure installation deviations while achieving standardized installation and reliable sealing of glass curtain walls. SUMMARY

[0031] Embodiment 1 The present embodiment discloses a glass curtain wall mounting structure of a steel member, such as Figures 1 to 5As shown: For a unit in a glass curtain wall with a single steel member 9 passing through it, a certain area in the middle is designated as the non-glass area, and the remaining areas are designated as glass areas. The steel member 9 is located within the non-glass area and is at a distance from the boundary of the non-glass area. At the boundary of the non-glass area, there are upper and lower spliced ​​metal rings 1. Between the metal rings 1 and the steel member 9, there are double-layered metal ring plates 2. Insulation material 5 is filled between the double-layered metal ring plates 2. The through holes of the metal ring plates 2 match the corresponding positions of the steel member 9 and are welded. There are gaps around the metal rings 1, allowing for the passage of insulation material. Seal 11 seals; the glass area divides the area below the non-glass area into the area to be installed first (glass 3) and the area above the non-glass area into the area to be installed later (glass 4). The glass 3 is installed first as the installation reference for the metal collar 1, and the glass 4 is installed later in the non-glass area. There is a partition rod 12 between the glass 3 and the glass 4 and between the glass 4. The two ends of the partition rod 12 are connected to the glass curtain wall frame and the metal collar 1, respectively. The partition rod 12 is sealed with the glass 3 and the glass 4 by the seal 13.

[0032] In this embodiment, preferably: Figures 1 to 4 As shown, the sealing element 11 adopts a telescopic bellows strip, and the telescopic bellows strip is pressed by the pressure strip 6. The pressure strip 6 is installed on the metal collar 1 and the metal ring plate 2 by fasteners 7 (such as stainless steel screws). When installing the telescopic bellows strip, it is necessary to ensure that sufficient expansion allowance is reserved.

[0033] In this embodiment, preferably: Figure 5 As shown, seal 213 is a combination of a hard rubber pad and weather-resistant sealant.

[0034] In this embodiment, preferably: Figures 2 to 4 As shown, a hard rubber gasket 8 is provided at the upper and lower joints of the metal collar 1. The upper and lower parts of the metal collar 1 are connected by a connector 10 (e.g., a stainless steel bolt) and the hard rubber gasket 8 is pressed tightly.

[0035] In this embodiment, preferably: Figure 1 and Figure 2 As shown, when the steel component 9 is tilted in the vertical direction, the non-glass area is vertically waist-shaped; when the steel component 9 is tilted in the horizontal direction, the non-glass area is horizontally waist-shaped.

[0036] In this embodiment, preferably: Figure 1 and Figure 2 As shown, the joint between the rear-installed glass 4 is located at the highest point of the non-glass area, while the joint between the first-installed glass 3 and the rear-installed glass 4 is located at the center height of the steel component 9.

[0037] In this embodiment, both the first-installed glass 3 and the second-installed glass 4 are laminated insulated high-strength glass, the insulation material 5 is insulation rock wool, and the partition rod 12 is aluminum alloy square tube.

[0038] Example 2 This embodiment discloses a glass curtain wall installation method with through-steel components, based on the glass curtain wall installation structure with through-steel components in Embodiment 1 above, including the following steps: S1. Before installation First, determine the size and position of the non-glass area based on the design dimensions, position and orientation of the steel component 9, ensuring that the steel component 9 remains within the non-glass area within a certain deviation range. Then, based on the size and position of the non-glass area, divide the glass area into appropriate areas for first-installed glass 3 and subsequent-installed glass 4. Next, fabricate the metal collar 1, metal ring plate 2, first-installed glass 3 and subsequent-installed glass 4, without opening through holes in the metal ring plate 2 initially.

[0039] S2, during installation After the main steel structure and the surrounding curtain wall are installed, the first glass 3 is installed first, then the lower part of the metal collar 1 is installed based on the first glass 3, and then the upper part of the metal collar 1 is spliced ​​and installed. Then, according to the actual position and outline of the steel component 9 at the installation position of the first layer metal ring plate 2, the through hole of the first layer metal ring plate 2 is processed, the first layer metal ring plate 2 is fitted onto the steel component 9 and welded and fixed to the steel component 9 after it is in place, then the insulation material 5 is filled, then the second layer metal ring plate 2 is installed, and then the metal ring plate 2 is sealed to the metal collar 1 around the perimeter through the sealing element 11. Then, the partition rod 12 is installed at the corresponding position, then the rear glass 4 is installed, and then the sealing element 2 13 is set between the partition rod 12 and the first glass 3 and the rear glass 4 for sealing.

[0040] This application employs a reasonable zoning method, ensuring that even if there are deviations in the size or installation of the steel component 9, it remains within the non-glass zone. This defines the outlines of the non-glass and glass zones, allowing for the pre-fabrication of relevant components. Only the location and outline of the through-holes in the metal ring plate 2 need to be determined on-site, ensuring a perfect match with the actual steel component 9. The initial installation of the glass 3 provides an installation benchmark for subsequent installations, enabling standardized installation for units with a single steel component 9 passing through the glass curtain wall. Furthermore, the metal ring plate 2 has gaps around its perimeter with the metal collar 1, sealed by a sealant 11. These gaps effectively absorb and accommodate dimensional or installation deviations in the steel component 9, preventing interference during installation. All critical connection points are sealed, ensuring effective sealing. Finally, the use of double-layered metal ring plates 2 filled with insulation material 5 ensures continuous insulation from the glass zone to the non-glass zone.

[0041] The embodiments described above are some, but not all, of the embodiments of this application. The detailed description of the embodiments of this application is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
