Description

Technical Field

[0001] This invention belongs to the field of curtain wall technology, and specifically refers to a cable-stayed metal panel assembled curtain wall system. Background Technology

[0002] Existing metal panel curtain wall systems are mostly traditional systems fixed with a keel. Current installation methods require pre-installing a large number of metal panel keels before installing aluminum panels one by one. The metal panels are fixed to the pre-installed keels on all four sides using angle brackets and their folded edges, or the flat edges are directly fixed to the keels. Traditional metal panel systems include metal keels, generally made of steel or aluminum; the metal panels are typically fixed on all four sides, with a 25mm folded edge on each side. During construction, workers must lay out, arrange, and anchor each keel. After the keel is installed, the aluminum panels are connected to the keels using angle brackets and self-tapping screws to form a complete aluminum panel system. Later, with the development of prefabricated curtain walls, some systems assemble keels into prefabricated frames of a certain size in the factory, then fix the metal panels (as described above) to the frame in the factory before on-site installation. Both of these methods involve a variety of aluminum panel curtain wall materials and cumbersome processes; when aluminum panels are used only as thin sheets, their material properties are not fully utilized; even with prefabricated design, these problems cannot be completely solved. Summary of the Invention

[0003] The purpose of this invention is to solve the above-mentioned technical problems and provide a cable-stayed metal panel prefabricated curtain wall system that uses the bearing capacity of the metal panel folds to resist horizontal loads (wind loads, horizontal live loads, seismic action, etc.) so that the metal panels are not supported by the rigidity of the keel.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A cable-stayed metal panel prefabricated curtain wall system is characterized by comprising an interlayer single aluminum panel unit group, which is installed on the main structure through a wind-resistant connection structure and an end connection structure. The interlayer single aluminum panel unit group includes a metal panel unit row, two vertical cables, and several cable clamp assemblies. The metal panel unit row includes several aligned metal panels with folded edges on the upper and lower sides. Horizontal T-shaped mounting grooves are respectively opened at both ends of the folded edges of the metal panels in the row. The vertical cables are inserted into receiving grooves through the notches of the aligned mounting grooves. The cross-sectional dimensions of the receiving grooves are larger than the cross-sectional dimensions of the vertical cables. Cable clamp assemblies for clamping the vertical cables are installed at each receiving groove. The cable clamp assemblies connect the rows of metal panels together. The cable clamp assembly includes two mating cable clamp half-units, which hold the vertical cables.

[0006] Preferably, the receiving groove includes a large circular hole and a notch, the width of which corresponds to the diameter of the vertical cable, and the diameter of the large circular hole is greater than the width of the notch.

[0007] Preferably, the cable clamp half unit includes a fixing groove, the vertical cable is located in the fixing groove, the fixing groove corresponds to a card insertion section, a positioning section and a connecting section, the card insertion section is inserted into the gap between the vertical cable and the groove wall of the receiving groove, the positioning section is attached to the inner wall of the folded edge of the metal plate, and the connecting section has bolt connection holes.

[0008] Preferably, the end connection structure includes an upper end connection structure and a lower end connection structure with identical structures. The upper end connection structure is installed between the upper end of the vertical cable and the main structure, and the lower end connection structure is installed between the lower end of the vertical cable and the main structure. The upper end connection structure includes an end steel support frame, a cable anchor head, an end adjusting screw, and an end fastening nut. The end steel support frame is fixed to the main structure, the lower end of the cable anchor head is fixed to the upper end of the vertical cable, and the upper end of the cable anchor head is connected to the end adjusting screw. The upper end of the adjusting screw passes through the crossbeam of the end support frame and is screwed on by the end fastening nut.

[0009] Preferably, the wind-resistant connection structure is located between the upper end connection structure and the lower end connection structure. The wind-resistant connection structure includes a wind-resistant clamp, an adjusting screw, a steel adapter, an adjusting nut, and a wind-resistant support frame. The wind-resistant clamp is clamped on the vertical cable, the adjusting screw is welded to the wind-resistant clamp, and the wind-resistant support frame is connected to the main structure. The steel adapter is U-shaped, with its open end welded to the wind-resistant support frame. The free end of the adjusting screw passes through the base plate of the steel adapter, and adjusting nuts are screwed onto the adjusting screws on both sides of the base plate.

[0010] The beneficial effects of this invention are as follows: This invention utilizes the self-bearing capacity of the metal plate folded edges and the bearing capacity of the stainless steel vertical cables to realize a lightweight prefabricated metal panel curtain wall system with a certain load-bearing capacity. This curtain wall system is quick and convenient to install, has fewer parts, a clear and understandable stress system, and produces a smooth and aesthetically pleasing finish. It also reduces the use of metal keel and lowers the load-bearing capacity requirements of the main structure. Attached Figure Description

[0020] The following examples illustrate possible implementations of the present invention, but are not intended to limit the scope of protection of the present invention.

[0021] like Figures 1 to 13As shown, this invention provides a cable-stayed metal panel prefabricated curtain wall system, comprising an interlayer single aluminum panel unit group 1, which is vertically installed on the main structure 4 via an end connection structure 2 and a wind-resistant connection structure 3. The interlayer single aluminum panel unit group 1 includes a metal panel unit row 11, two vertical cables 12, and several cable clamp assemblies 13. The metal panel unit row 11 comprises several vertically arranged metal panels 111, which are aluminum alloy panels with a facade dimension of 1m x 0.5m and upper and lower folded edges 1111 each 60mm wide. The number of cable clamp assemblies 13 is four times the number of metal panels 111. Aligned horizontal T-shaped mounting grooves 112 are respectively opened on the upper and lower folded edges of the rows of metal plates. The diameter of the vertical cable is 6mm-8mm. The vertical cable 12 is inserted into the receiving groove 114 through the notch 113 of the aligned mounting groove 112. Preferably, the receiving groove 114 is a large round hole, and the notch 113 is square. The width of the notch 113 corresponds to the diameter of the vertical cable 12. The diameter of the large round hole is larger than the width of the notch. The size of the large round hole of the receiving groove 114 is larger than the diameter of the vertical cable. Cable clamp assemblies 13 for clamping the vertical cable 12 are installed at each receiving groove 114. The cable clamp assembly 13 includes two mating cable clamp half units 131. The metal plate unit rows are connected by the cable clamp assembly and the vertical cable. Preferably, the cable clamp half-unit 131 includes a fixing groove 1310 through which the vertical cable 12 passes. The fixing groove 1310 has a corresponding insert section 1311, a positioning section 1312, and a connecting section 1313. The insert section 1311 is inserted into the gap between the vertical cable 12 and the groove wall of the receiving groove 114. The positioning section 1312 is attached to the inner wall of the folded edge of the metal plate. The connecting section 1313 has a bolt connection hole 1314. The insert section and the positioning section are concentric and stepped semi-tubular. The outer diameter of the insert section is smaller than that of the positioning section. The connecting section is a convex plate and forms an L-shape with the positioning section. The two cable clamp half-units are connected by connecting section bolts 1315. The semi-circular channels of the two cable clamp half-units form a clamping channel for the vertical cable.

[0022] Specifically, the end connection structure 2 includes an upper end connection structure and a lower end connection structure with identical structures. The upper end connection structure is installed between the upper end of the vertical cable 12 and the main structure 4, and the lower end connection structure is installed between the lower end of the vertical cable and the main structure 4. The upper end connection structure includes an end steel support frame 211, a cable anchor head 212, an end adjusting screw 213, and an end fastening nut 214. The end steel support frame 211 is fixed on the main structure 4. The lower end of the cable anchor head 212 is fixed to the upper end of the vertical cable 12. The upper end of the cable anchor head 212 is connected to the end adjusting screw 213. The upper end of the end adjusting screw 213 passes through the crossbar of the end support frame 211 and is screwed on by the end fastening nut 215. The wind-resistant connection structure 3 is located between the upper and lower connection structures. This structure includes a wind-resistant clamp 31, an adjusting screw 32, a steel adapter 33, adjusting nuts 34, and a wind-resistant support frame 35. The wind-resistant clamp 31 is clamped onto the vertical cable 12. The adjusting screw 32 is welded to the clamp 31. The wind-resistant support frame 35 is connected to the main structure 4. The steel adapter 33 is U-shaped, with its open end welded to the support frame 35. The free end of the adjusting screw 32 passes through the base plate of the steel adapter 33, and adjusting nuts 34 are screwed onto the adjusting screws 32 on both sides of the base plate. The screws at the anchor heads of the vertical cables at the top and bottom are inserted into the pre-installed end support frames on the main structure, and appropriate preload is applied. The top and bottom end support frames need to bear the horizontal force, preload, and the system's own weight, while the two wind-resistant structures in between only bear the horizontal force.

[0023] The 60mm wide folded edge of the metal sheet of this invention has a certain load-bearing capacity to resist horizontal forces. This folded edge provides sufficient support for the metal sheet to resist various horizontal loads and ensures that deformation meets current specifications. The folded edge of the metal sheet is milled with mounting grooves for fixation. 6mm-8mm stainless steel vertical cables provide overall support for the metal panel system, and a certain pre-tension is applied to the vertical cables. Cable clamps are used to fix the metal sheet to the stainless steel vertical cables. These cable clamps can provide horizontal and vertical support for the metal sheet. The cable clamps can be inserted into the folded edge receiving groove of the metal sheet to provide support. Pre-molded rubber rings can be used at the connection between the cable clamps and the folded edge of the aluminum sheet to achieve vibration and noise reduction as needed. Several metal sheets can be pre-installed on vertical cables of a certain length, and then hoisted and pre-tensioned as a whole.

[0024] The curtain wall system is quick to install. Only a small number of top and bottom connection structures and wind-resistant structures are pre-installed on the main structure. Most of the other assembly is completed on the ground and then hoisted for installation.
