Description

Technical Field

[0001] This application relates to the technical field of cable net curtain walls, and particularly to a support device for a vertically self-balanced hyperbolic cable net curtain wall. Background Art

[0002] A cable net curtain wall is a new type of building curtain wall system. The structure of a cable net curtain wall mainly consists of prestressed cables, connecting clamps, and glass panels. The four corner points of the glass are connected to the cables through clamps, and the glass and glass are connected with silicone sealant to form a stable structural system. It has the characteristics of good permeability, safety, flexibility, environmental protection, energy saving, and convenient maintenance technology.

[0003] The planar cable net structure relies on the cable force to establish the out-of-plane stiffness. Sufficient pre-tension must be given to the cables to ensure the calculated stiffness and allowable deflection of the structure. However, the huge pre-tension will inevitably cause the surrounding support structure of the cable net to bear a large load. The saddle-shaped cable net curtain wall can reduce the cable force applied to the surrounding support structure to a certain extent. However, the saddle-shaped cable net curtain wall will make the outer facade of the glass curtain wall present an arc-shaped facade, thus forming a cable net surface with a double-curvature saddle shape. It is difficult for the curvature of the cable net surface to exactly match the curvature of the outer facade of the curtain wall, resulting in a large installation error in the glass curtain wall, which has deficiencies. Utility Model Content

[0004] In order to improve the problem of large installation errors in the glass curtain wall caused by the difficulty in exactly matching the curvature of the outer facade of the curtain wall and the curvature of the cable net surface, this application provides a support device for a vertically self-balanced hyperbolic cable net curtain wall.

[0005] The support device for a vertically self-balanced hyperbolic cable net curtain wall provided by this application adopts the following technical solutions:

[0006] A support device for a vertically self-balanced hyperbolic cable net curtain wall includes columns, wind-resistant cables, reverse bow cables, and balance cables. The wind-resistant cables and the reverse bow cables are both arc-shaped. The columns are perpendicular to the wind-resistant cables and are arranged in multiple numbers along the length direction of the wind-resistant cables. The length direction of the reverse bow cables is parallel to the length direction of the columns. A top support assembly is arranged between the reverse bow cables and the columns, and the top support assembly is used to control the curvature of the reverse bow cables. A tension assembly is arranged between the ends of the reverse bow cables and the columns, and the tension assembly is used to adjust the tension of the reverse bow cables. The balance cables are used to control the structural stability between adjacent reverse bow cables.

[0007] By adopting the above technical solution, construction workers fix both ends of the reverse bow cable to the column through the top support assembly and the tension assembly, and at the same time make the reverse bow cable present an arched shape and act on the column, thereby dispersing the acting force of the cable net on the surrounding support structure, reducing the load force of the cable net on the support structure, and at the same time making the wind resistance cable fit the curtain wall, thereby reducing the curvature difference between the cable net surface and the outer surface of the curtain wall, and further improving the installation accuracy of the glass curtain wall.

[0008] Optionally, the top support assembly includes a support seat arranged on the column. A plurality of the support seats are arranged along the length direction of the column. A support rod is hinged on the support seat. The lengths of the support rods along the length direction of the column are different. One end of the support rod facing away from the support seat is hinged with a connecting seat. A pressing block is detachably arranged on the connecting seat. An arched cable groove for the reverse bow cable to pass through is jointly formed between the pressing block and the connecting seat.

[0009] By adopting the above technical solution, by adjusting the length of the support rod, the reverse bow cable presents an arched structure with different curvatures, thereby changing the dispersion effect of the reverse bow cable on the cable net load force through the column. At the same time, the detachably arranged pressing block facilitates the construction workers to technically adjust the fixing position of the reverse bow cable.

[0010] Optionally, a fixing seat is arranged between the support seat and the column. A wind cable groove for the wind resistance cable to pass through is jointly formed between the fixing seat and the support seat.

[0011] By adopting the above technical solution, the wind resistance cable is close to the column, thereby reducing the curvature difference between the cable net surface and the outer surface of the curtain wall. At the same time, the wind resistance cable also reduces the steel cable consumption of the cable net in the direction of the wind resistance cable.

[0012] Optionally, the tension assembly includes a tensioning seat and an end seat arranged on the column. The tensioning seat is located between the end seat and the support seat. An installation ear is fixedly arranged at the end of the reverse bow cable. The installation ear is rotatably connected to the end seat. A main shaft is rotatably arranged on the tensioning seat. A reversing wheel is coaxially arranged on the main shaft. The end of the reverse bow cable bypasses the reversing wheel. A pressing rod is arranged on the main shaft. A tension wheel is rotatably arranged on the pressing rod. The tension wheel is used to press the reverse bow cable between the reversing wheel and the end seat. A fixing member for fixing the pressing rod is arranged on the tensioning seat.

[0013] By adopting the above technical solution, the construction worker rotates the pressing rod, and the pressing rod drives the tension wheel to squeeze the reverse bow cable between the reversing wheel and the end seat, thereby adjusting the tension of the reverse bow cable. At the same time, the position of the adjusted pressing rod is fixed by the fixing member, so as to facilitate the construction worker to make timely adjustments. At the same time, when the reverse bow cable is slack due to being in a tensioned state for a long time, the construction worker can rotate the pressing rod to timely compensate the tension of the reverse bow cable.

[0014] Optionally, the fixing member includes a ratchet wheel coaxially arranged on the main shaft, and a ratchet spur meshing with the ratchet wheel is rotatably arranged on the tensioning seat.

[0015] By adopting the above technical solution, through the cooperation of the ratchet wheel and the ratchet spur, the possibility of the pressure rod rotating is effectively reduced.

[0016] Optionally, a driving groove with a polygonal cross-section is coaxially opened on the main shaft, and the driving groove is used to drive the main shaft to rotate.

[0017] By adopting the above technical solution, construction workers insert a professional tool into the driving groove and drive the pressure rod to rotate, reducing the possibility of the pressure rod being accidentally rotated.

[0018] Optionally, the cross-section of the connecting seat is C-shaped, a pressing plate is detachably arranged on the concave side of the C-shape of the connecting seat, and a balance cable groove for the balance cable to pass through is jointly opened on the connecting seat and the pressing plate.

[0019] By adopting the above technical solution, the balance cable is close to the anti-arch cable, which is beneficial to improving the effect of stabilizing the structural state of the anti-arch cable.

[0020] Optionally, a spirit level is arranged on the support rod.

[0021] By adopting the above technical solution, it is convenient for construction workers to adjust the support rod to a horizontal state, so that the tension on the anti-arch cable acts vertically on the column, reducing the possibility of the support seat being damaged by the shear side force.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. Construction workers fix both ends of the anti-arch cable on the column through the top support assembly and the tension assembly, and at the same time make the anti-arch cable present an arch shape and act on the column, thereby dispersing the acting force of the cable net on the surrounding support structure, reducing the load force of the cable net on the support structure, and at the same time making the wind resistance cable fit the curtain wall, thereby reducing the curvature difference between the cable net surface and the outer surface of the curtain wall, and further improving the installation accuracy of the glass curtain wall;

[0024] 2. Construction workers rotate the pressure rod, and the pressure rod drives the tension wheel to squeeze the anti-arch cable between the reversing wheel and the end seat, thereby adjusting the tension of the anti-arch cable, and at the same time fixing the position of the adjusted pressure rod through the fixing member, so as to facilitate construction workers to make timely adjustments. At the same time, when the anti-arch cable is slack after being in a tensioned state for a long time, construction workers can timely compensate the tension of the anti-arch cable by rotating the pressure rod;

[0025] 3. Facilitate the construction workers to adjust the support rod to a horizontal state, so that the tension on the anti-arch cable acts vertically on the column, reducing the possibility of damage to the support seat due to shear lateral force. Description of the Drawings

Detailed Description of the Invention

[0029] The following will Figure 1 - Figure 2 further describe the present application in detail with reference to the attached drawings.

[0030] The embodiment of the present application discloses a vertically self-balanced double-curved cable net curtain wall support device.

[0031] Referring to Figure 1 , a vertically self-balanced double-curved cable net curtain wall support device includes a column 1, a wind-blocking cable 2, an anti-arch cable 3 and a balance cable 4. The wind-blocking cable 2 and the anti-arch cable 3 are both arc-shaped. The column 1 is perpendicular to the wind-blocking cable 2 and a plurality of columns 1 are arranged along the length direction of the wind-blocking cable 2. The length direction of the anti-arch cable 3 is parallel to the length direction of the column 1. The balance cable 4 is used to control the structural stability between two adjacent anti-arch cables 3.

[0032] Referring to Figure 1 and Figure 2 , a top support assembly 5 is arranged between the anti-arch cable 3 and the column 1. The top support assembly 5 is used to control the arc of the anti-arch cable 3. A tension assembly 6 is arranged between the end of the anti-arch cable 3 and the column 1. The tension assembly 6 is used to adjust the tension of the anti-arch cable 3.

[0033] Referring to Figure 1 and Figure 2, the top support assembly 5 includes support seats 51 arranged on the vertical column 1. There are multiple support seats 51 arranged along the length direction of the vertical column 1. A support rod 52 is hinged on the support seat 51. A spirit level 12 is arranged on the support rod 52. The lengths of the support rods 52 along the length direction of the vertical column 1 are different. One end of the support rod 52 facing away from the support seat 51 is hinged with a connecting seat 53 with a C-shaped cross-section. Pressing blocks 54 are bolted to both ends of the C-shape of the connecting seat 53.

[0034] Refer to Figure 1 and Figure 2 , a bow cable groove 55 for the anti-arch cable 3 to pass through is jointly opened between the pressing block 54 and the connecting seat 53. A pressing plate 10 is bolted to the concave side of the C-shape of the connecting seat 53. A balance cable groove 11 for the balance cable 4 to pass through is jointly opened on the connecting seat 53 and the pressing plate 10. A fixing seat 7 is bolted to the side of the support seat 51 facing the vertical column 1. The fixing seat 7 is bolted to the vertical column 1. A wind cable groove 8 for the wind resistance cable 2 to pass through is jointly opened between the fixing seat 7 and the support seat 51.

[0035] The construction workers fix the wind resistance cable 2 on the fixing seat 7 through the wind cable groove 8 on the support seat 51 and the fixing seat 7, then fix the balance cable 4 on the connecting seat 53 through the balance cable groove 11 on the pressing plate 10 and the connecting seat 53, and at the same time fix the anti-arch cable 3 on the connecting seat 53 through the bow cable groove 55 between the pressing block 54 and the connecting seat 53. Finally, the tension of the anti-arch cable 3 fixed on the vertical column 1 is adjusted by the tension assembly 6.

[0036] The balance cable 4 adjusts the structural stability between two adjacent anti-arch cables 3. The anti-arch cable 3 presents an arch shape and acts on the vertical column 1, so that the anti-arch cable 3 bears the vertical load force. The vertical column 1 is arranged in an arc along the wind resistance cable 2, so that the wind resistance cable 2 bears the lateral load force, thereby dispersing the acting force of the cable net on the surrounding support structure. At the same time, the wind resistance cable 2 fits the curtain wall, thereby reducing the curvature difference between the curvature of the cable net surface and the curvature of the outer surface of the curtain wall.

[0037] Refer to Figure 1 and Figure 2 , the tension assembly 6 includes a tensioning seat 61 and an end seat 62 bolted to the vertical column 1. The tensioning seat 61 is located between the end seat 62 and the support seat 51. An installation ear 63 is welded to the end of the anti-arch cable 3. The installation ear 63 is rotatably connected to the end seat 62. A main shaft 64 is rotatably connected to the tensioning seat 61. A driving groove 9 with a polygon cross-section is coaxially opened on the main shaft 64. The driving groove 9 is used to drive the main shaft 64 to rotate. A reversing wheel 65 is coaxially welded to the main shaft 64. The end of the anti-arch cable 3 bypasses the reversing wheel 65.

[0038] Refer to Figure 1 and Figure 2, a pressure rod 66 is welded on the main shaft 64, a tension wheel 67 is rotatably connected to the pressure rod 66, and the tension wheel 67 is used to press the reverse bow cable 3 between the reversing wheel 65 and the end seat 62. A fixing member 68 for fixing the pressure rod 66 is arranged on the tensioning seat 61. The fixing member 68 includes a ratchet wheel 681 coaxially welded on the main shaft 64. A ratchet thorn 682 meshing with the ratchet wheel 681 is rotatably arranged on the tensioning seat 61. A stop block 13 is welded on the tensioning seat 61. A compression spring 14 is propped between the stop block 13 and the ratchet thorn 682, and the compression spring 14 presses the ratchet thorn 682 against the ratchet wheel 681.

[0039] After both ends of the reverse bow cable 3 are fixed on the column 1, the construction worker inserts a professional tool into the driving groove 9 and rotates it, so that the main shaft 64 drives the pressure rod 66 to rotate around the axis of the main shaft 64. The pressure rod 66 drives the tension wheel 67 to squeeze the reverse bow cable 3 between the reversing wheel 65 and the end seat 62, thereby adjusting the tension of the reverse bow cable 3. During the rotation of the pressure rod 66, under the action of the compression spring 14, the ratchet thorn 682 always presses the ratchet thorn 682 against the ratchet wheel 681, thus preventing the rotation of the main shaft 64.

[0040] The implementation principle of a vertically self-balanced hyperbolic cable net curtain wall support device in an embodiment of the present application is as follows: The construction worker fixes the wind resistance cable 2 on the fixing seat 7 through the wind resistance cable groove 8 on the support seat 51 and the fixing seat 7, then fixes the balance cable 4 on the connecting seat 53 through the balance cable groove 11 on the pressing plate 10 and the connecting seat 53, and at the same time fixes the reverse bow cable 3 on the connecting seat 53 through the bow cable groove 55 between the pressing block 54 and the connecting seat 53. Finally, the tension of the reverse bow cable 3 fixed on the column 1 is adjusted through the tension assembly 6.

[0041] The balance cable 4 adjusts the structural stability between two adjacent reverse bow cables 3. The reverse bow cable 3 presents an arch shape and acts on the column 1, so that the reverse bow cable 3 bears the vertical load force. The columns 1 are arranged in an arc along the wind resistance cable 2, so that the wind resistance cable 2 bears the horizontal load force, thereby dispersing the acting force of the cable net on the surrounding support structure, and at the same time making the wind resistance cable 2 fit the curtain wall, thus reducing the curvature difference between the curvature of the cable net surface and the curvature of the outer surface of the curtain wall.

[0042] After both ends of the reverse bow cable 3 are fixed on the column 1, the construction worker inserts a professional tool into the driving groove 9 and rotates it, so that the main shaft 64 drives the pressure rod 66 to rotate around the axis of the main shaft 64. The pressure rod 66 drives the tension wheel 67 to squeeze the reverse bow cable 3 between the reversing wheel 65 and the end seat 62, thereby adjusting the tension of the reverse bow cable 3. During the rotation of the pressure rod 66, under the action of the compression spring 14, the ratchet thorn 682 always presses the ratchet thorn 682 against the ratchet wheel 681, thus preventing the rotation of the main shaft 64.

[0043] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
