Description

Technical Field

[0001] This invention relates to the field of support technology, specifically to a supportless device and construction method for cable-stayed steel truss floor decking. Background Technology

[0002] Prestressed cable-stayed structures represent the trend of modern construction technology towards lightweight, prefabricated, and intelligent construction. Essentially, they represent a deep integration of prestressed tensioning technology and temporary steel structure support systems. Suitable for theaters, factories, stadiums, and other venues where large-span, large-space concrete beams or slabs are being poured, traditional full-span scaffolding is extremely expensive. Instead, a cable (or high-strength steel strand) tensioning system is installed on structural columns or specially designed temporary supports. Steel trusses or steel beams are placed below the formwork as primary and secondary load-bearing beams. A certain amount of prestress (tension force) is applied to the cables beforehand, causing them to rise and support the load-bearing steel beams and formwork system below, jointly bearing the weight of the poured concrete. The tensioning system is released or removed after the concrete reaches its design strength.

[0003] In the application of existing prestressed steel cable supportless devices, there are drawbacks such as simple structure and inability to move quickly after being fixed to the ground structure. As a result, after the steel truss or floor deck of a construction site is completed, a lot of time is required to disassemble and reposition the prestressed steel cable supportless device, resulting in slow construction speed and hindering the promotion of prestressed steel cable supportless devices.

[0016] 2. When using this application, the hydraulic sensor detection end, which is fixedly embedded on the outside of the fixed frame, is located inside the elastic water storage component. The hydraulic sensor monitors the hydraulic pressure inside the elastic water storage component. During the process of the steel cable being wound through the elastic water storage component, the external condition of the steel cable affects the internal hydraulic pressure of the elastic water storage component. It is only necessary to install a support frame six with a bottom fixed connection to the fixed frame on the square shell to detect the steel cable breakage during the winding process, ensuring the safety of the steel cable, reducing the occurrence of accidents, slowing down the steel cable breakage detection process, and reducing the cost of using the cable support-free device.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example: Figures 1-15 As shown, the present invention provides a cable-stayed device for steel truss floor decking, including a support structure 1, which supports a cable structure 2. The support structure 1 includes multiple guide rails 11, and a connecting component is provided between two adjacent guide rails 11. The cable structure 2 includes a support component slidably installed on one of the guide rails 11, a cable control component provided on the top of the support component, a steel cable 213 installed on the cable control component, and a deflection component installed on the outside of the steel cable 213.

[0021] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The connecting assembly between the two guide rails 11 includes a hinge 112 and a mounting plate 17. The hinge 112 is fixedly installed between the two guide rails 11, allowing the two guide rails 11 to rotate relative to each other. The mounting plate 17 is fixedly installed on the side of one of the guide rails 11 away from the hinge 112, thus limiting the relative movement between the two guide rails 11. Multiple insertion holes 18 on the outer side of the mounting plate 17 each have insert rods 111 inserted into them. One end of each insert rod 111 passes through the outer wall of an adjacent guide rail 11 and extends into the interior of the guide rail 11. A hydraulic cylinder 19 is provided on one side of the connecting frame 110, which is fixedly connected between the insertion rods 111. The outer wall of the hydraulic cylinder 19 is fixedly connected to the inner wall of the guide rail 11, and the piston end of the hydraulic cylinder 19 is fixedly connected to the connecting frame 110. The hydraulic cylinder 19 is controlled to work to make the connecting frame 110 move. After the multiple insertion rods 111 pass through the multiple insertion holes 18, the relative position between the mounting plate 17 and the two guide rails 11 cannot change. The multiple guide rails 11 are installed together by multiple connecting components, so that the multiple guide rails 11 are on the same horizontal line, and the support structure 1 is in the unfolded state.

[0022] Both sides of the guide rail 11 are fixedly connected to partition plates 16. The cable structure 2 installed on the guide rail 11 is located between the two partition plates 16. The two partition plates 16 limit the movement of the cable structure 2 to prevent the cable structure 2 from detaching from the guide rail 11. The support structure 1 has multiple mounting slots 12 and 15 on the front and rear sides. The mounting slots 15 correspond one-to-one with the mounting slots 12. The mounting slots 15 and 12 are internally connected. The magnet 14 inside the mounting slot 15 is fixedly connected to the guide rail 11. The magnet 14 abuts against the grounding plate 13 inside the mounting slot 12. The magnet 14 fixes the iron grounding plate 13 by magnetic attraction. The grounding plate 13 is rotatably connected to the guide rail 11 and can rotate to contact the ground.

[0023] Specifically, such as Figure 1 , Figure 4 , Figure 6 , Figure 7 and Figure 8 In the support assembly, support frame 1 21 is set on the top of guide rail 11. Multiple wheels 232 are fixedly connected to both sides of the bottom of support frame 1 21. The bottom of wheels 232 abuts against guide rail 11 to reduce the friction between support frame 1 21 and guide rail 11 during movement. Multiple wheels 25 are fixedly installed on the bottom of two support frames 24 fixedly connected to the bottom of support frame 1 21. Support frame 24 is set inside guide rail 11. The bottom of wheels 25 abuts against the bottom of the inner cavity of guide rail 11. Wheels 25 support support frame 1 21 to reduce the force required for support frame 1 21 to move. Support frame 24 limits support frame 1 21 to achieve sliding connection between support frame 1 21 and guide rail 11.

[0024] A dual-axis hydraulic cylinder 26 is installed at the bottom of support frame 24. Two support frames 3 27 are fixedly installed on the outside of the dual-axis hydraulic cylinder 26 at the bottom of support frame 24. Friction plates 28 are fixedly connected to the two piston ends of the dual-axis hydraulic cylinder 26. The side of the friction plate 28 away from the dual-axis hydraulic cylinder 26 is rough. Controlling the operation of the dual-axis hydraulic cylinder 26 pushes the two friction plates 28 to move and contact the inside of the support structure 1, so that the friction plates 28 rub against the guide rail 11, thereby braking support frame 24 and support frame 1 21.

[0025] One of the support frames 24 has an operating lever 3 fixedly connected to its top. The operating lever 3 pulls the cable structure 2 to move synchronously.

[0026] Specifically, such as Figure 8 and Figure 9 In the cable control assembly, the gearbox 22, two brakes 210, and two support frames 211 are all fixedly installed on the top of the support frame 21. A forward and reverse motor 23 is fixedly connected to the top of the gearbox 22. The output end of the forward and reverse motor 23 is fixedly connected to the input end of the gearbox 22. The drive shaft 29, which is fixedly connected to the output end of the gearbox 22, passes through the two brakes 210 and the two support frames 211. The drive shaft 29 is rotatably connected to the support frame 211 and can rotate on its own.

[0027] A take-up frame 212 is fixedly installed on the outside of the drive shaft 29. One end of the steel cable 213 is fixedly connected to the take-up frame 212 and part of the steel cable 213 is wrapped around the outside of the take-up frame 212. The take-up frame 212 is set between two support frames 211, so that the take-up frame 212 is stably supported. The forward and reverse motors 23 are controlled to rotate forward or reverse. The rotation of the drive shaft 29 drives the take-up frame 212 to rotate to wind or unwind the steel cable 213. Therefore, the cable control component is controlled to work and control the winding or unwinding of the steel cable 213.

[0028] Specifically, such as Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 and Figure 14The steering assembly consists of a support frame 214 fixedly connected between the outer walls of the two brakes 210, a square outer shell 215 inside the support frame 214, a spring tube 216 fixedly connected to one side of the square outer shell 215, a connecting pipe 217 fixedly connected to one end of the spring tube 216, a water pump 218 fixedly connected to one end of the connecting pipe 217, and a water tank 219 fixedly connected to the inlet end of the water pump 218. The water tank 219 and the water pump 218 are both fixedly installed on the top of the gearbox 22, so the relative positions of the support frame 214, the water pump 218, and the water tank 219 remain unchanged. A circular hole 234 is provided on the outer side of the support frame 214. A spring tube 216 passes through the circular hole 234 and can extend and retract freely. Guide grooves 220 are provided on both sides of the support frame 214. Two ball bearings 221 are installed inside the guide grooves 220. One end of a connecting shaft 222 fixedly inserted inside the ball bearings 221 is fixedly connected to the square shell 215. With the cooperation of the four connecting shafts 222 and the four ball bearings 221 with the guide grooves 220, the square shell 215 is slidably installed inside the support frame 214, and the force required for the square shell 215 to move is small.

[0029] The square outer shell 215 has support frames 6 223 at both the bottom and top of its inner cavity. The outer wall of the bottom support frame 6 223 is fixedly connected to the square outer shell 215, and a water baffle 233 is fixedly connected to the top of the support frame 6 223. A hollow sponge block 224 is placed between the two support frames 6 223, and the hollow sponge block 224 is fixedly connected to the top support frame 6 223. The hollow sponge block 224 moves synchronously with the top support frame 6 223. Both support frames 6 223 have openings at their tops. Multiple mounting slots 235 are provided, and two connecting shafts 225 are provided inside the mounting slots 235. The connecting shafts 225 are rotatably connected to the support frame 223. Ball bearings 226 are fixedly installed on the outside of the connecting shafts 225. When the top of the steel cable 213 passes through the two support frames 223, the water shield 233 and the hollow sponge block 224, the multiple ball bearings 226 abut against the steel cable 213, so that the part of the steel cable 213 located between the two support frames 223 remains vertical.

[0030] On both sides of the top of the square outer shell 215, there are mounting grooves 230 and two threaded grooves 227. The threaded grooves 227 are connected to the bottom of the inner cavity of the mounting grooves 230. The two mounting grooves 230 are equipped with fixed side plates 228. The fixed side plates 228 are fixedly connected to the top support frame 223. The fixed side plates 228 and the top support frame 223 move synchronously. Bolts 229 are inserted into the threaded grooves 227. The top of the bolts 229 penetrates the adjacent fixed side plates 228. The bolts 229 are connected to the square outer shell 215 and the fixed side plates 228 through the threaded structure. Therefore, by rotating the bolts 229 to disengage them from the threaded grooves 227, the fixed side plates 228 can be removed from the square outer shell 215, thus completing the disassembly of the top support frame 223 and the hollow sponge block 224.

[0031] In summary, the cable supportless device, consisting of support structure 1, cable structure 2, and operating rod 3, is connected to a human-machine interface device and power supply for power control. This is an existing technology application and will not be elaborated upon here.

[0032] The construction method for cable-stayed unsupported devices is as follows: Step 1, Transportation: In two adjacent connecting components, the hinge 112 and the mounting plate 17 are symmetrically arranged. That is, in the connecting component between the first and second left, the hinge 112 is located on the rear side, and the mounting plate 17 is located on the front side; in the connecting component between the second and third left, the hinge 112 is located on the front side, and the mounting plate 17 is located on the rear side. As mentioned above, multiple connecting components install multiple guide rails 11 together, and the positions of the hydraulic cylinder 19, connecting frame 110, and multiple insert rods 111 that cooperate with the mounting plate 17 change accordingly. Multiple guide rails 11 can be folded together, so that the support structure 1 can be transported after folding, reducing the space required for transporting the support structure 1, improving the convenience of movement of the support structure 1, and controlling the position of the cable structure 2. The multiple cable structures 2 being staggered does not affect the folding of the support structure 1.

[0033] Step 2, Installation: After transporting the support structure 1 to the construction location, the support structure 1 is unloaded and unfolded. Then, multiple grounding plates 13 are flipped over to contact the ground. The grounding plates 13 are fixed by pressing them down with heavy objects, inserting grounding nails after making holes in the top of the grounding plates 13, welding, etc., thus completing the fixed installation of the support structure 1.

[0034] Step 3, Construction: Install two or more cable-free support devices into the preset positions according to construction needs.

[0035] The position of the cable structure 2 is adjusted. After the position of the cable structure 2 is adjusted, the dual-axis hydraulic cylinder 26 in the cable structure 2 is controlled to work to push the friction plate 28 to rub against the inner wall of the guide rail 11, thereby completing the braking work of the cable structure 2.

[0036] Subsequently, one end of the steel cable 213, which passes through the two support frames 223 and the hollow sponge block 224, is fixedly connected to the steel truss or floor deck. This allows one steel truss or floor deck to be connected to two or more steel cables 213 as needed during construction. Then, the corresponding cable structures 2 are controlled to work collaboratively to wind up the steel cable 213. Since the steel cable 213 enters the building from above and connects to the steel truss or floor deck, and is deflected by the building's support, the windup of the steel cable 213 lifts the steel truss or floor deck. With the cooperation of two or more cable structures 2, the steel truss or floor deck is hoisted to the preset position, and the cables... The position of structure 2 can be adjusted under the guidance of guide rail 11, making the installation conditions of support structure 1 more relaxed and improving the installation efficiency of support structure 1. The two brakes 210 in the control cable structure 2 stop the transmission shaft 29, the rotation of the take-up frame 212 is restricted, the steel cable 213 is braked, and the steel truss or floor deck remains suspended under the prestressing action of the steel cable 213 at different positions. The steel truss or floor deck can be pre-installed without the need to build scaffolding to support it. The subsequent construction fixes the steel truss or floor deck to the building, thus completing the supportless installation of the steel truss or floor deck.

[0037] Cable structures 2 can be installed on multiple guide rails 11 in a support structure 1. The position of the cable structures 2 can be adjusted. The setting of multiple support structures 1 can meet the needs of multiple steel trusses or floor slabs for support-free construction, reduce the frequency of movement and adjustment of support structures 1, ensure the high efficiency of the application of support structures 1, reduce economic losses, and improve construction speed.

[0038] Step 4, Maintenance: During the winding and unwinding process of the steel cable 213, multiple ball bearings 226 installed inside the upper and lower support frames 6 223 support the steel cable 213, so that the part of the steel cable 213 located between the two support frames 6 223 is in a vertical state. Under the support of multiple ball bearings 1 221, the square outer shell 215 can move flexibly, so the square outer shell 215 will not affect the winding and unwinding operation of the steel cable 213. During this process, the spring tube 216 contracts and unfolds.

[0039] After the steel cable 213 completes its work and separates from the steel truss or floor slab, the water pump 218 is controlled to draw lubricating oil from the water storage tank 219. The water pump 218 delivers lubricating oil into the square outer shell 215 through the connecting pipe 217 and the spring pipe 216. Since the amount of lubricating oil delivered into the square outer shell 215 is limited, and the water baffle 233 is fixedly installed on the top of the bottom support frame 6 223, and the water baffle 233 is fitted on the bottom outer side of the vertical part of the steel cable 213 located between the two support frames 6 223, the lubricating oil will not leak under the action of the water baffle 233. The lubricating oil is stored inside the square outer shell 215 and absorbed by the hollow sponge block 224. The hollow sponge block 224 is fitted on the outside of the steel cable 213 and applies lubricating oil to the outside of the steel cable 213 to maintain the steel cable 213 and ensure its service life.

[0040] Step 5, parts replacement: Control the rotation of bolt 229 so that the bottom end of bolt 229 leaves the inside of threaded groove 227, then the upper support frame 223 and hollow sponge block 224 can be disassembled. The hollow sponge block 224, which has been in contact with steel cable 213 and has a lot of impurities stuck to it, can be replaced.

[0041] A support frame 223 with a fixed bracket 4 at the bottom can be installed inside the square outer shell 215. After the steel cable 213 passes through the elastic water storage component 5 fixedly connected inside the fixed bracket 4, the elastic water storage component 5 wraps around the outside of the steel cable 213. The detection end of the hydraulic sensor 6 fixedly embedded on the outside of the fixed bracket 4 is set inside the elastic water storage component 5. The hydraulic sensor 6 monitors the hydraulic pressure inside the elastic water storage component 5. During the process of the steel cable 213 being wound through the elastic water storage component 5, the external condition of the steel cable 213 affects the hydraulic pressure inside the elastic water storage component 5. By simply installing the support frame 223 with the fixed bracket 4 at the bottom on the square outer shell 215, the breakage of the steel cable 213 can be detected during the winding process, ensuring the safety of the steel cable 213, reducing the occurrence of accidents, slowing down the process of detecting the breakage of the steel cable 213, and reducing the cost of using the cable support-free device.
