Description

Technical Field

[0001] This utility model relates to the field of curtain wall technology, and in particular to a horizontally exposed and vertically concealed large-span steel-aluminum composite glass curtain wall system. Background Technology

[0002] Framed glass curtain walls come in several forms, including horizontally exposed and vertically concealed, horizontally concealed and vertically exposed, fully exposed, and fully concealed. Utilizing the transparency of glass, they enhance the aesthetics of buildings and are commonly used in ultra-high-rise spaces, large glass conference centers, exhibition centers, airports, and other similar projects. However, as the span of all-glass curtain walls increases, the wind load also increases, placing higher demands on the load-bearing capacity of the glass curtain wall's frame. Traditional frame structures use bent and welded refined steel, resulting in excessively high processing costs. Using conventional aluminum-clad steel systems leads to bulky columns, which are aesthetically unappealing. The bulky columns of conventional aluminum-clad steel systems do not meet project requirements, and conventional refined steel systems fail to meet energy-saving requirements, necessitating the use of high-grade glass, which is also expensive. Furthermore, for increasingly irregularly shaped projects, the cold bending value of the glass decreases with each subsequent step. This means that projects where single-cavity glass can be constructed using cold bending methods (e.g., a cold bending value of 30mm) may require hot bending to create single-curved or even double-curved glass with greater warpage values ​​due to the use of two cavities and the use of lamination. This directly doubles the project's material costs, increases construction expenses, and increases construction difficulty. Project costs have increased dramatically.

[0003] In addition, given my country's vast climatic regions, for public building projects in cold areas and those with strict energy consumption requirements, such as glass curtain wall projects with a common energy-saving parameter K-value requirement of 1.7W / ㎡·K, most practices in northern regions involve using a configuration of three glass panes and two cavities. This is achieved by improving the energy-saving parameters of the glass to meet the overall energy-saving requirements, or simply by improving the energy-saving performance of the frame. However, when the thermal insulation strip exceeds a certain length (30mm) and participates in the stress, it is detrimental to the stress on the profile. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a horizontally visible and vertically concealed large-span steel-aluminum composite glass curtain wall system that can solve the problem that all-glass curtain walls are difficult to balance aesthetics, stability and construction cost.

[0005] Therefore, the present invention adopts the following technical solution:

[0006] A horizontally visible, vertically concealed, large-span steel-aluminum composite glass curtain wall system includes a large-span horizontal beam, columns, single-cavity glass, a horizontal beam base, and a column sub-frame. The large-span horizontal beam is welded to the columns. The large-span horizontal beam is fixedly connected to the horizontal beam base, and the columns are fixedly connected to the column sub-frame via first and second channel steel, respectively. A pressure plate is connected to the front side of the horizontal beam base via a thermal insulation strip. Mounting grooves for placing the single-cavity glass are provided between the horizontal beam base and the pressure plate, and on both sides of the thermal insulation strip. At least two support plates are provided in the mounting groove below the single-cavity glass, and at least two hook edges are provided in the mounting groove above the single-cavity glass. The single-cavity glass is sealed to the horizontal beam base and to the pressure plate via adhesive strips. The single-cavity glass is fixedly connected to the column sub-frame via sealant.

[0007] Based on the above technical solutions, the present invention may also adopt the following further technical solutions, or combine these further technical solutions:

[0008] The large-span beam, the column, the first channel steel, and the second channel steel are made of steel structure. The first channel steel is welded to the large-span beam, and the second channel steel is welded to the column.

[0009] Both the crossbeam base and the column sub-frame are made of aluminum alloy, and insulating gaskets are provided between the crossbeam base and the first channel steel, and between the column sub-frame and the second channel steel.

[0010] A decorative cover is connected to the outdoor side of the pressure plate, and the decorative cover is sealed and fixed to the single-cavity glass with sealant.

[0011] Both the pressure plate and the decorative buckle cover are made of aluminum alloy.

[0012] The width of the large-span beam is at least twice the width of the column.

[0013] The length of the heat insulation strip is 35mm.

[0014] Both ends of the tray and the hook edge extend beyond the heat insulation strip.

[0015] The column sub-frame is composed of two separate aluminum alloy profiles, and the front side of the aluminum alloy profile is provided with a T-shaped pressure block.

[0016] The pressure plate is fixedly connected to the crossbeam base by a number of first screws, the crossbeam base is fixedly connected to the first channel steel by a number of second screws, the side of the support plate is fixedly connected to the crossbeam base and the first channel steel by a number of third screws, and the pressure block is fixedly connected to the second channel steel by a number of fourth screws.

[0017] Compared with existing technologies, this utility model has the following advantages and beneficial effects: The use of single-cavity glass, combined with support plates and hooks, facilitates the cold bending process for bending single-cavity glass in irregularly shaped projects, significantly reducing material costs; the use of longer thermal break strips achieves higher energy-saving parameters; the combined use of steel and aluminum leverages the advantages of both materials, ensuring building stability while significantly saving costs; for horizontal structural members, the use of wider horizontal beams than columns, with the two welded together, ensures the safety of the curtain wall system.
