Description

Technical Field

[0001] This utility model relates to the field of curtain wall technology, and in particular to a longitudinally long-span steel-aluminum composite glass curtain wall system that is horizontally concealed and vertically exposed. 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] 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 longitudinally large-span steel-aluminum composite glass curtain wall system that is horizontally concealed and vertically visible, which can solve the problem that framed glass curtain walls are difficult to balance aesthetics, stability and construction cost.

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

[0006] A longitudinally integrated steel-aluminum composite glass curtain wall system with horizontal concealment and vertical visibility includes horizontal beams, large-span columns, single-cavity glass panels, column bases, and horizontal beam sub-frames. The horizontal beams are fixedly connected to the large-span columns via connecting components. The large-span columns are fixedly connected to the column bases via first screws. The horizontal beams are fixedly connected to the horizontal beam sub-frames via pressure blocks and second screws. A pressure plate is connected to the front side of the column base via a thermal insulation strip. Mounting grooves for placing the single-cavity glass panels are provided between the column base and the pressure plate, and on both sides of the thermal insulation strip. The single-cavity glass panels are sealed to the column base and the pressure plate via adhesive strips. The single-cavity glass panels are fixedly connected to the horizontal beam sub-frames 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 crossbeam and the large-span column are made of steel structure, the column base and the crossbeam sub-frame are made of aluminum alloy, and insulating gaskets are provided between the large-span column and the column base, and between the crossbeam and the crossbeam sub-frame.

[0009] 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 abut 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.

[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 column is greater than the width of the crossbeam.

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

[0014] The connecting plate is a T-shaped connecting plate, which includes mutually perpendicular crossbeam side plates and a glass support plate. The crossbeam and the side plates are fixedly connected through the crossbeam side plates. The crossbeam side plates are parallel to the crossbeam. The glass support plate is located below the single-cavity glass, and a rigid pad is provided between the glass support plate and the single-cavity glass.

[0015] The crossbeam subframe 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 and the column base are fixedly connected by several fourth screws.

[0017] Compared with the prior art, this utility model has the following advantages and beneficial effects: it adopts single-cavity glass and sets a longer thermal insulation strip to achieve better energy-saving parameters for the frame; by combining steel and aluminum materials, it leverages the advantages of both materials, ensuring building stability while greatly saving costs; the longitudinal components bear the load, and the large-span columns adopt a wider size than the horizontal beams, and the two are connected by connecting components to ensure the safety of the curtain wall system.
