[0002] With the increasing height of domestic buildings in recent years, the architectural shapes have become more and more diverse; at the same time, in order to pursue more lighting and a wider field of view, the size of the glass panels in the lighting area has also become larger and larger; this has also brought many problems, such as the installation and maintenance of large glass. With the rise of large-span and large-space architectural designs in railway stations, airports, large public places, and high-end commercial buildings, the transparency and lightness of cable curtain walls are increasingly favored by designers. After several years or more than ten years of operation and use, problems with cable curtain wall components have gradually emerged.

DETAILED DESCRIPTION

[0028] To make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in combination with the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Example:

[0030] A supporting structure for replacing a curtain wall comprises a supporting frame 01, a supporting fixture 02, and a supporting assembly 03. The supporting fixture 02 comprises a supporting block 201, a supporting block 202, an outer protective block 203, a vertical cable mounting block A204, a first vertical cable rope 205, a vertical cable mounting block B206, a transverse cable mounting block 207, a transverse cable rope 208, a transverse cable locking block 209, a vertical cable mounting block C210, a second vertical cable rope 211, and a vertical cable mounting block D212. The supporting block 202 is fixedly arranged on the supporting block 201, and the outer protective block 203 is detachably installed on the outer side of the supporting block 201. The curtain wall body 04 is installed and placed on the supporting block 202 between the supporting block 201 and the outer protective block 203. The vertical cable mounting block A204 is fixedly arranged on the inner side of the supporting block 201. The first vertical cable rope 205 is detachably fixed to the vertical cable mounting block A204 through the vertical cable mounting block B206. A horizontal cable mounting block 207 is fixedly provided on the outside, and a horizontal cable rope 208 is detachably mounted and fixed on the horizontal cable mounting block 207 through a horizontal cable locking block 209. A vertical cable mounting block C210 is fixedly provided on the outside of the horizontal cable mounting block 207, and a second vertical cable rope 211 is detachably mounted and fixed on the vertical cable mounting block C210 through a vertical cable mounting block D212;

[0031] The supporting assembly 03 includes a first beam 301, a second beam 302, a truss 303, a lifting member 304 and an adsorption member 305. The truss 303 is connected and fixed to the first beam 301 and the second beam 302. The truss 303 is fixedly installed at the bottom of the first beam 301 and the second beam 302. The top of the first vertical rope 205 and the second vertical rope 211 are fixedly installed on the first beam 301. The lifting member 304 and the adsorption member 305 are fixedly installed on the truss 303.

[0032] In this embodiment, the lifting member 304 includes a lifting cross bar 341 and a supporting block 342. The lifting cross bar 341 can be detachably installed on the truss 303. A supporting block 342 is installed at the front end of the lifting cross bar 341, and the supporting block 342 is used to support the curtain wall body 04; the adsorption member 305 includes an adsorption cross bar 351 and an electric suction cup 352. The adsorption cross bar 351 can be detachably installed on the truss 303. An electric suction cup 352 is installed at the end of the adsorption cross bar 351. The electric suction cup 352 is used to absorb the curtain wall body 04. The electric suction cup 352 can ensure that the curtain wall body 04 is not affected by the replacement of the cable component. In order to further reduce the settlement of the glass panel, an adjustable lifting cross bar 341 is also provided.

[0033] In this embodiment, a more optimal setting is that the bottom of the second vertical cable 211 and one end of the horizontal cable 208 are both connected with a cable force buffer device 05, which is an adjustable anchor. The adjustable anchor is preset and fixed on the ground, and finally connected to the second vertical cable 211. When the cable is loose or overloaded, the cable preload is automatically compensated to ensure the safety of the entire curtain wall. When the cable is subjected to live load (mainly typhoon), the cable force buffer device 05 compensates for the change in the length of the cable caused by the change in the shape of the cable (string shape) through the compression spring (the cable force buffer device 05 is the compression spring inside the adjustable anchor), and the internal force of the cable is controlled within the design range. After the live load disappears, the spring of the cable force buffer device 05 is stretched back to its original state, the cable tension is restored, and the length of the horizontal cable 208 does not increase due to creep or creep.

[0034] In this embodiment, the supporting structure replaces the curtain wall by the following method:

[0035] (1) Fixing the curtain wall body: first install the first crossbeam and the second crossbeam, assemble and fix the truss on the side close to the curtain wall body, and fix the curtain wall body in the horizontal and vertical directions through the adsorption member and the supporting member, so that the curtain wall body is fixed.

[0036] (2) Connect the curtain wall body: Fix and then install the support block on the inside of the curtain wall body, support the bottom of the curtain wall body, install the outer protection block on the outside of the curtain wall body and connect it to the support block in a detachable manner.

[0037] (3) The old stainless steel rigging on the curtain wall body was dismantled: First, the existing vertical cables were unloaded. Before unloading, the connection between the unloaded vertical cables and the clamps was checked one by one to see if they were disconnected. Then the rope tension was unloaded by 30% each time. During unloading, the changes in the internal forces of other load ropes should be closely observed. The glue joints of the curtain wall body in the column where the unloaded rope is located and the two adjacent columns should be observed with a width observation scale. The changes in the position of the curtain wall body and the glue joint width should be observed. In the key areas determined by simulation analysis, the crack observation instrument should be used to observe the changes in the glue joint width in real time.

[0038] (4) Remove the vertical cable after unloading starting from the bottom. After removing the connecting bolts between the anchor head and the ear plate, tie the traction rope. After the top anchor head and the lifting hook are firmly fixed, remove the connecting bolts. Control the electric hoist to slowly descend. At the same time, pull the traction rope at the lower end to ensure that the steel cable does not touch the glass panel during the descent process.

[0039] (5) Installing the rope: First, before the rope is officially lifted, the thread engagement of the adjusting end of the rope should be checked. When the rope is in a stress-free state, the thread engagement should be smooth. If not, the cause should be found and eliminated. When installing the rope, the rope with a small diameter should be straightened against the direction of the rope before being lifted. The rope with a large diameter should be placed on the rope drum first, and then the rope drum should be rotated while being lifted. The lifting speed of the rope should be synchronized with the rotation speed of the rope drum to ensure that the rope is lifted in a natural state. It is forbidden to directly lift the rope vertically when the rope is not opened. If the rope is in a spiral state when it is lifted, the rope lifting should be stopped immediately, and the rope lifting can be continued only after the rope drum is rotated until the rope is in a natural state. When lifting, appropriate protective measures should be taken for the anchors at both ends, and the protective layer outside the rope should not fall off or be damaged.

[0040] (6) The specific installation of the rope includes installing the first vertical cable, the second vertical cable and the horizontal cable. First, install the first vertical cable between the vertical cable mounting block A and the vertical cable mounting block B. After the vertical cable mounting block A and the vertical cable mounting block B are detachably connected and firmly connected, the horizontal cable is installed on the horizontal cable mounting block. The horizontal cable locking block is detachably connected to the horizontal cable mounting block to fix the horizontal cable. Then, the second vertical cable is installed on the cable force buffer device. The second vertical cable is installed between the vertical cable mounting block C and the vertical cable mounting block D. The vertical cable mounting block C and the vertical cable mounting block D are detachably connected. It should be noted that the cable is prestressed and tensioned in 4 steps. Finally, re-tighten the clamp, apply thread tightening glue to the threaded part of the pin screw and tighten the screw with a torque of 3N·m.

[0041] (7) Real-time monitoring of cable network safety: Sensors are installed on the curtain wall body, cables and support components. The output end of the sensor is connected to the input end of the collector, the output end of the collector is connected to the input end of the network, the output end of the network is connected to the input end of the client-data collection, the output end of the network is also connected to the input end of the server, the output end of the server is connected to the input end of the multi-function module, and the output end of the multi-function module is connected to the input end of the multi-client synchronous display.

[0042] Among them, the multifunctional module includes the functions of online calculation of monitoring indicators, real-time viewing of performance indicators, online evaluation, real-time grasp of structural status, synchronous early warning, and automatic triggering of early warning information.
