Description

Technical Field

[0001] This utility model relates to the field of curtain wall technology, and in particular to a longitudinally large-span steel-aluminum composite glass curtain wall system with horizontal openness and vertical concealment. 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 building's aesthetics. Common column types are aluminum alloy or aluminum-clad steel. They are frequently used in conventional commercial projects. For projects such as ultra-high-rise spaces, ultra-large glass conference centers, exhibition centers, and airports, the increased span of the curtain wall columns leads to greater wind loads, thus placing higher demands on the load-bearing capacity of the glass curtain wall's keel. Traditional methods using all-steel keels with bent and welded joints are too costly and difficult to construct. Using conventional aluminum-clad steel systems results in bulky, unsightly columns.

[0003] Furthermore, for an increasing number of 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) now require lamination because they use two cavities. This necessitates the use of hot bending processes to create single-curved or even double-curved glass with greater warpage values, directly doubling material costs, increasing construction expenses, and making construction more difficult. The overall project cost increases dramatically. To address this issue, simply improving the energy-saving performance of the frame is insufficient; when the thermal break strip exceeds a certain length (30mm) and participates in the load-bearing, it becomes detrimental to the profile.

[0004] Furthermore, 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, the common practice in northern regions is to use a configuration of three panes of glass in two chambers, achieving a lower overall energy efficiency by improving the energy-saving parameter of the glass. Some projects, due to the tilting of the glass, even require four panes of glass according to glass curtain wall specifications, resulting in excessive glass weight and inconvenient construction. In some irregularly shaped projects prioritizing aesthetics, where the building surface is designed as curved, the glass needs to be adjusted accordingly. Excessively thick glass is unsuitable for cold bending, and using hot bending to manufacture curved glass would directly double the project's material costs, increase construction expenses, and increase construction difficulty. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a longitudinally large-span steel-aluminum composite glass curtain wall system with horizontal visibility and vertical concealment, which can solve the problem that all-glass curtain walls are difficult to balance aesthetics, stability, thermal performance, and construction cost.

[0006] Therefore, the present invention adopts the following technical solution:

[0007] A longitudinally integrated, long-span steel-aluminum composite glass curtain wall system with horizontally visible and vertically concealed elements includes horizontal beams, long-span columns, single-cavity glass panels, horizontal beam bases, and column sub-frames. The horizontal beams and long-span columns are fixedly connected via connecting components. The horizontal beams and horizontal beam bases are fixedly connected via first screws. The long-span columns and column sub-frames are fixedly connected via pressure blocks and second screws. 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 panels 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 panels, and at least two hook edges are provided in the mounting groove above the single-cavity glass panels. The single-cavity glass panels are sealed to the horizontal beam base and to the pressure plate via adhesive strips. The single-cavity glass panels are fixedly connected to the column sub-frames via sealant.

[0008] Based on the above technical solutions, the present invention may also adopt the following further technical solutions, or combine these further technical solutions:

[0009] The crossbeam and the large-span column are made of steel structure, and the crossbeam base and the column sub-frame are both made of aluminum alloy. Insulating gaskets are provided between the crossbeam and the crossbeam base, and between the large-span column and the column sub-frame.

[0010] The connecting assembly includes a crossbeam connector and a connecting plate. The crossbeam has slots on both sides for placing the crossbeam connector. A connecting area is provided on one side of each slot. The crossbeam connector includes a back plate and a side plate. The back plate is fixedly connected to the large-span column by bolts. The side plate can be inserted into the slot and abuts against the connecting area, and the surfaces of both are flush. The connecting plate is fixedly connected to the side plate and the connecting area by a third screw.

[0011] 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.

[0012] Both the pressure plate and the decorative buckle cover are made of aluminum alloy.

[0013] The width of the large-span column is greater than the width of the crossbeam.

[0014] The length of the heat insulation strip is 35mm.

[0015] Both ends of the tray and the hook edge extend beyond the heat insulation strip.

[0016] 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.

[0017] The pressure plate is fixedly connected to the crossbeam base by a number of fourth screws, and the side of the support plate is fixedly connected to the crossbeam base by a number of fifth screws.

[0018] Compared with the prior art, 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, greatly reducing material costs; By setting longer thermal insulation strips, higher energy-saving parameters are achieved; The combined use of steel and aluminum leverages the advantages of both materials, ensuring building stability while significantly saving costs; For longitudinal structural members, the use of wider columns than horizontal beams, with the two connected by connecting components, ensures the safety of the curtain wall system.

The horizontal beam 1 and the large-span column 2 are fixedly connected by a connecting component 6. The horizontal beam 1 and the horizontal beam base 4 are fixedly connected by a first screw. The large-span column 2 and the column sub-frame 5 are fixedly connected by a pressure block 8 and a second screw. A pressure plate 8 is connected to the front side of the horizontal beam base 4 by a heat insulation strip 7. There are mounting grooves for placing the single-cavity glass 3 between the horizontal beam base 4 and the pressure plate 8, and on both sides of the heat insulation strip 7. At least two support plates 91 are provided in the mounting groove below the single-cavity glass 3, and at least two hook edges 92 are provided in the mounting groove above the single-cavity glass 3. The single-cavity glass 3 is sealed with the horizontal beam base 4 and the pressure plate 8 by adhesive strips 10.

When the single-cavity glass 3 needs to be cold-bent, the lower edge of the single-cavity glass 3 is first fixed in the two support plates 91, and then one side of the upper edge of the single-cavity glass 3 is fixed to one of the hook edges 92. The single-cavity glass 3 can then be cold-bent on the other side above the single-cavity glass 3. After the cold bending is completed, the other side of the single-cavity glass 3 is fixed to the remaining hook edge.

[0026] In this embodiment, the adhesive strip 10 is an EPDM adhesive strip.

[0027] In this embodiment, the sealant 11 includes double-sided adhesive and silicone structural adhesive.

[0028] The crossbeam 1 and the large-span column 2 are made of steel structure, while the crossbeam base 4 and the column sub-frame 5 are made of aluminum alloy. Insulating gaskets 12 are provided between the crossbeam 1 and the crossbeam base 4, and between the large-span column 2 and the column sub-frame 5, to prevent the steel and aluminum from reacting chemically.

[0029] The connecting assembly 6 includes a crossbeam connector 61 and a connecting plate 62. The crossbeam 1 has slots 15 on both sides for placing the crossbeam connector 61.

For simply supported beams with spans between 8 and 13 meters, the column depth can be increased to 600mm. Furthermore, the right-angle steel column employs multi-cavity welding to enhance stability.

[0033] The length of the thermal insulation strip 7 is 35mm.
