Description

Technical Field

[0001] This invention relates to the field of hanging basket construction technology, and in particular to a construction method for an integral prefabricated grid panel for preventing hanging baskets from falling. Background Technology

[0002] Hanging baskets are the main equipment in cantilever construction, and can be divided into four types according to their structural form: truss type, cable-stayed type, steel type, and hybrid type. Based on the requirements of concrete cantilever construction technology and design drawings for hanging baskets, this paper comprehensively compares the characteristics, weight, type of steel used, and construction technology of various types of hanging baskets. The design principles for hanging baskets are: light weight, simple structure, sturdy and stable, easy to move forward and disassemble, strong reusability, small deformation under stress, and sufficient space under the basket to provide a large working surface, which is beneficial for the construction of reinforcing steel and formwork.

[0003] The term "hanging basket construction" refers to the use of a suspended basket method for on-site, segmented cantilever construction when pouring concrete for large-span cantilever beam bridges. It eliminates the need for scaffolding and large cranes. Compared to other methods, hanging basket construction offers advantages such as a lighter structure, simpler and more convenient assembly, and the absence of additional weight.

[0004] Currently, most hanging baskets are assembled by bolting adjacent grid panels, beams, and columns together. At the same time, steel sections are welded to connect the corners of the sides and front of the adjacent grid panels into a whole. As the assembly height changes, this installation method makes it inconvenient for workers to disassemble the upper grid panels as needed, and tools are required for disassembly and assembly. Therefore, it is not convenient for construction and assembly, and reduces construction efficiency. Summary of the Invention

[0005] To address the technical problem that existing hanging baskets are inconvenient for workers to disassemble the upper grid panels as needed during assembly, this invention proposes a construction method for an integrally assembled grid panel for preventing hanging baskets from falling.

[0006] This invention proposes a construction method for an integrally assembled grid panel for preventing hanging basket falls, the construction method comprising:

[0007] Step 1: Determine the installation location of the hanging basket grid panel according to the needs, and measure the dimensions;

[0008] Step 2: The full protection of the hanging basket consists of bottom protection and facade protection. The facade protection is erected on the bottom. The bottom protection and facade protection are composed of several grid panels, beams, and columns. According to the size of the hanging basket, the bottom protection is assembled from multiple 2.75*2m grid panels, and the size of the grid panels for the facade protection is 1.5*1.8m.

[0009] Step 3: Assemble the bottom protection on the ground using grid panels. The grid panels are connected to the beams and columns using angle steel bolts.

[0010] Step 4: After the bottom protection is assembled, use a tower crane and a winch on the bridge deck to hoist it to the bottom of the hanging basket, and then use a precision-rolled threaded steel rod to connect it to the bottom of the hanging basket.

[0011] Step 5: Assemble the facade protection. Secure the corner joints of the bottom protection grid panels and the facade protection grid panels together using a clamping mechanism.

[0012] Step 6: Secure two adjacent grid panels of the facade protection together using a connecting device;

[0013] Step 7: After the single-sided assembly of the facade protection is completed, use a tower crane or bridge deck winch to hoist the entire structure to the top of the bottom cover. Weld the columns on the facade protection to the bottom cover until the facade protection is installed all around the bottom cover.

[0014] Preferably, the clamping mechanism includes an L-shaped steel plate, with through holes on both sides of the L-shaped steel plate. A T-shaped sliding column is slidably inserted into the inner wall of the through hole. A rotating rod is mounted on the inner wall of the T-shaped sliding column via a bearing. One end of the rotating rod extends outside the T-shaped sliding column and is fixedly sleeved with a rotating handle. A gear is fixedly sleeved on the other end of the rotating rod.

[0015] With the above technical solution, holes aligned with the perforations are also opened on two adjacent grid plates of the facade protection. The T-shaped sliding column is inserted into the grid plate through the perforations, and the rotating handle is rotated to drive the rotating rod to rotate. The rotation of the rotating rod drives the gear to rotate.

[0016] Preferably, a housing is fixedly connected to the inner wall of one end of the T-shaped sliding column, and an mounting plate is fixedly installed on the inner wall of the housing. The two sides of the gear are respectively installed on the inner wall of the housing and one side of the mounting plate through bearings. The surface of the gear has arc-shaped grooves distributed in a ring array. The surface of the mounting plate has sliding grooves distributed in a ring array. A T-shaped sliding rod is slidably engaged with the inner wall of the sliding groove. A connecting rod is fixedly connected to one side of the T-shaped sliding rod, and the surface of the connecting rod is slidably engaged with the inner wall of the arc-shaped groove.

[0017] Through the above technical solution, the rotation of the gear drives the connecting rod to move along the inner wall of the arc groove, and the movement of the connecting rod drives the T-shaped slide rod to move along the inner wall of the slide groove of the mounting plate, so that the T-shaped slide rod can extend and retract.

[0018] Preferably, one end of the housing extends out of the T-shaped sliding rod, and its surface is provided with telescopic grooves arranged in a ring array, and the surface of the T-shaped sliding rod is slidably engaged with the inner wall of the telescopic groove.

[0019] Through the above technical solution, the movement of the T-shaped slide bar causes it to move along the inner wall of the expansion groove, thereby making it contact the surface of the grid plate.

[0020] Preferably, the connecting device includes two clamping plates, an elastic contraction mechanism, and a fixing mechanism. The elastic contraction mechanism clamps and positions the two sides of two adjacent grid plates through the two clamping plates, and the fixing mechanism fixes two adjacent grid plates together through the two clamping plates.

[0021] Preferably, the elastic contraction mechanism includes a sleeve column disposed between the two clamping plates, a support column fixedly installed on the inner wall of the sleeve column, a connecting sleeve slidably engaged on both sides of the surface of the support column, one end of the connecting sleeve being fixedly connected to one side of the clamping plate, and compression springs respectively sleeved on both sides of the surface of the support column, one end of the compression spring being fixedly connected to the surface of the support column, and the free end of the compression spring being fixedly connected to the other end of the connecting sleeve.

[0022] Through the above technical solution, pulling the clamping plate causes the connecting sleeve to move along the surface of the support column, and stretches and compresses the spring to deform and generate elastic force.

[0023] Preferably, the inner sidewall of the connecting sleeve is provided with symmetrically distributed limit plates, and limit grooves are opened on both sides of the support column. The surface of the limit plate is slidably engaged with the inner wall of the limit groove.

[0024] The above technical solution ensures that the connecting sleeve can only move in one direction on the support column, thereby preventing the connecting sleeve from rotating on the support column.

[0025] Preferably, the fixing mechanism includes positioning studs symmetrically distributed on the clamping plate via bearings. One end of the positioning stud is fixedly sleeved with a handle, and a housing is fixedly installed on the other side of the clamping plate. The other end of the positioning stud extends into the housing and its surface is threaded with a threaded block. The surface of the threaded block slides and engages with the inner wall of the housing.

[0026] Through the above technical solution, rotating the handle drives the positioning stud to rotate, and the rotation of the positioning stud causes the threaded block to move along the inner wall of the casing on its surface.

[0027] Preferably, an I-shaped ring is fixedly installed on the inner wall of the threaded block, a telescopic spring is sleeved on the inner surface of the I-shaped ring, a locking block is fixedly sleeved on the surface of the telescopic spring, and grooves are distributed in a ring array on the surface of the I-shaped ring, and the surface of the locking block is slidably engaged with the inner wall of the groove.

[0028] Through the above technical solution, the movement of the locking block along the inner wall of the groove causes the telescopic spring to deform.

[0029] Preferably, the surface of the mesh plate for facade protection is provided with a slot, and the surfaces of the sleeve, the threaded block and the locking block are all engaged with the inner wall of the slot.

[0030] With the above technical solution, when the threaded block moves to a certain position, the elastic force of the telescopic spring causes the locking block to engage with the locking slot.

[0031] The beneficial effects of this invention are as follows:

[0032] 1. By setting a clamping mechanism, it is easy to fix the corner position of the bottom protection grid plate and the vertical protection grid plate together. By turning the handle, the rotating rod is driven to rotate. The rotation of the rotating rod drives the gear to rotate. The rotation of the gear drives the connecting rod to move along the inner wall of the arc groove. The movement of the connecting rod drives the T-shaped slide rod to move along the inner wall of the mounting plate's slide groove, so that the T-shaped slide rod can extend and retract along the inner wall of the expansion groove. Thus, disassembly and assembly can be carried out without the need for additional tools.

[0033] 2. By setting up a connecting device, it is easy to fix two adjacent grid panels of the facade protection together. The elastic contraction mechanism makes the clamping plate and the grid panel in close contact. At the same time, by turning the handle, the positioning stud is driven to rotate. The rotation of the positioning stud causes the threaded block to move along the inner wall of the casing. When the threaded block moves to a certain position, the elasticity of the telescopic spring causes the locking block to engage with the locking slot. Similarly, the grid panels can be quickly installed and removed without the need for additional tools. Attached Figure Description

[0050] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0051] A method for constructing an integral prefabricated grid panel for preventing hanging basket falls, the method comprising:

[0052] Step 1: Determine the installation location of the hanging basket grid panel according to the needs, and measure the dimensions;

[0053] Step 2: The full protection of the hanging basket consists of bottom protection and facade protection. The facade protection is erected on the bottom. The bottom protection and facade protection are composed of several grid panels, beams, and columns. According to the size of the hanging basket, the bottom protection is assembled from multiple 2.75*2m grid panels, and the size of the grid panels for the facade protection is 1.5*1.8m.

[0054] Step 3: Assemble the bottom protection on the ground using grid panels. The grid panels are connected to the beams and columns using angle steel bolts.

[0055] Step 4: After the bottom protection is assembled, use a tower crane and a winch on the bridge deck to hoist it to the bottom of the hanging basket, and then use a precision-rolled threaded steel rod to connect it to the bottom of the hanging basket.

[0056] Step 5: Assemble the facade protection. Secure the corner joints of the bottom protection grid panels and the facade protection grid panels together using clamping mechanism 1.

[0057] Step 6: Fix two adjacent grid panels of the facade protection together using the connecting device 2;

[0058] Step 7: After the single-sided assembly of the facade protection is completed, use a tower crane or bridge deck winch to hoist the entire structure to the top of the bottom cover. Weld the columns on the facade protection to the bottom cover until the facade protection is installed all around the bottom cover.

[0059] Reference Figures 1-15 The connecting device 2 includes two clamping plates 21, an elastic contraction mechanism, and a fixing mechanism. The elastic contraction mechanism clamps and positions the two sides of two adjacent grid plates through the two clamping plates 21, and the fixing mechanism fixes the two adjacent grid plates together through the two clamping plates 21.

[0060] like Figures 6-12As shown, in order for the two clamping plates 21 to clamp the two sides of the grid plate, the elastic contraction mechanism includes a sleeve post 22 disposed between the two clamping plates 21, and grooves adapted to the surface of the sleeve post 22 are provided on the surface of the adjacent grid plate to facilitate the positioning of the sleeve post 22. A support post 221 is fixedly installed on the inner wall of the sleeve post 22. A connecting sleeve 222 is slidably engaged on both sides of the surface of the support post 221. One end of the connecting sleeve 222 is fixedly connected to one side of the clamping plate 21. Compression springs 223 are respectively sleeved on both sides of the surface of the support post 221. One end of the compression spring 223 is fixedly connected to the surface of the support post 221, and the free end of the compression spring 223 is fixedly connected to the other end of the connecting sleeve 222. By pulling the clamping plate 21 outward, the movement of the clamping plate 21 causes the connecting sleeve 222 to move along the surface of the support post 221, and stretches the compression spring 223 to deform and generate elastic force. After the clamping plate 21 is released, the clamping plate 21 clamps the surface of the grid plate under the action of the elastic force of the compression spring 223.

[0061] In order to limit the movement of the connecting sleeve 222, limit plates 224 are symmetrically distributed on the inner sidewall of the connecting sleeve 222. Limit grooves 225 are opened on both sides of the support column 221. The surface of the limit plate 224 is slidably engaged with the inner wall of the limit groove 225. The movement of the limit plate 224 along the inner wall of the limit groove 225 limits the movement of the connecting sleeve 222 on the support column 221.

[0062] like Figures 6-10 as well as Figures 13-15 As shown, in order to fix the clamping plate 21 to the mesh plate, thereby connecting two adjacent mesh plates together, the fixing mechanism includes positioning studs 23 symmetrically distributed on the clamping plate 21 via bearings. One end of the positioning stud 23 is fixedly sleeved with a handle 231, and a housing 232 is fixedly installed on the other side of the clamping plate 21. The other end of the positioning stud 23 extends into the housing 232, and a threaded block 233 is threaded onto its surface. The surface of the threaded block 233 slides and engages with the inner wall of the housing 232. By rotating the handle 231, the positioning stud 23 is rotated. The rotation of the positioning stud 23 causes the threaded block 233 to move along the inner wall of the housing 232 on its surface, and the threaded block 233... An I-shaped ring 234 is fixedly installed on the inner wall of the device. A telescopic spring 235 is sleeved on the inner surface of the I-shaped ring 234. A locking block 236 is fixedly sleeved on the surface of the telescopic spring 235. The surface of the I-shaped ring 234 has grooves 237 distributed in a ring array. The surface of the locking block 236 slides and engages with the inner wall of the groove 237. A slot 238 is provided on the surface of the grid plate for vertical protection. The surfaces of the housing 232, the threaded block 233, and the locking block 236 are all engaged with the inner wall of the slot 238. When the threaded block 233 moves to a certain position, the elastic force of the telescopic spring 235 inside the I-shaped ring 234 drives the locking block 236 to move out along the inner wall of the groove 237 and engage with the slot 238.

[0063] By setting the connecting device 2, it is easy to fix two adjacent grid panels of the facade protection together. The elastic contraction mechanism makes the clamp 21 in close contact with the grid panel. At the same time, by turning the handle 231, the positioning stud 23 is driven to rotate. The rotation of the positioning stud 23 causes the threaded block 233 to move along the inner wall of the sleeve 232 on its surface. When the threaded block 233 moves to a certain position, the elastic force of the telescopic spring 235 causes the locking block 236 to engage with the locking groove 238. Similarly, the grid panel can be quickly installed and removed without the need for additional tools.

[0064] like Figures 2-5 As shown, in order to fix the corner position connecting the bottom protection grid plate and the facade protection grid plate together, the clamping mechanism 1 includes an L-shaped steel plate 101. Both sides of the L-shaped steel plate 101 are provided with through holes 102, and holes aligned with the through holes 102 are also provided on the two adjacent grid plates of the facade protection. A T-shaped sliding column 103 is slidably inserted into the inner wall of the through hole 102. A rotating rod 104 is installed on the inner wall of the T-shaped sliding column 103 through a bearing. One end of the rotating rod 104 extends to the outside of the T-shaped sliding column 103 and is fixedly sleeved with a rotating handle 105. The other end of the rotating rod 104 is fixedly sleeved with a gear 106. The T-shaped sliding column 103 is inserted into the grid plate through the through hole 102. By rotating the rotating handle 105, the rotating rod 104 is driven to rotate. The rotation of the rotating rod 104 drives the gear 106 to rotate.

[0065] To fix the T-shaped sliding column 103 to the grid plate via the L-shaped steel plate 101, a housing 107 is fixedly connected to the inner wall of one end of the T-shaped sliding column 103. A mounting plate 108 is fixedly installed on the inner wall of the housing 107. The gear 106 is mounted on both sides of the housing 107 and one side of the mounting plate 108 respectively via bearings. The surface of the gear 106 has arc-shaped grooves 109 arranged in a circular array. The surface of the mounting plate 108 has sliding grooves 110 arranged in a circular array. A T-shaped sliding rod 111 is slidably engaged with the inner wall of the sliding groove 110. A connecting rod 112 is fixedly connected to one side of the T-shaped sliding rod 111. The surface of 12 slides and engages with the inner wall of the arc groove 109. The rotation of the gear 106 drives the connecting rod 112 to move along the inner wall of the arc groove 109. The movement of the connecting rod 112 drives the T-shaped slide rod 111 to move along the inner wall of the slide groove 110 of the mounting plate 108, so that the T-shaped slide rod 111 moves. A T-shaped slide column 103 extends from one end of the housing 107 and its surface is provided with telescopic grooves 113 in a ring array. The surface of the T-shaped slide rod 111 slides and engages with the inner wall of the telescopic groove 113. The movement of the T-shaped slide rod 111 causes it to move along the inner wall of the telescopic groove 113, which facilitates contact with the surface of the grid plate.

[0066] By setting a clamping mechanism 1, it is easy to fix the corner position of the bottom protection grid plate and the vertical protection grid plate together. By turning the handle 231, the rotating rod 104 is driven to rotate. The rotation of the rotating rod 104 drives the gear 106 to rotate. The rotation of the gear 106 drives the connecting rod 112 to move along the inner wall of the arc groove 109. The movement of the connecting rod 112 drives the T-shaped slide rod 111 to move along the inner wall of the slide groove 110 of the mounting plate 108, so that the T-shaped slide rod 111 can extend and retract along the inner wall of the telescopic groove 113, thus allowing disassembly and assembly without the need for additional tools.

[0067] Working principle: When in use, the bottom protection is assembled on the ground with grid plates, beams and columns using angle steel bolts. After the bottom protection is assembled, it is hoisted to the bottom of the hanging basket using a tower crane and a winch on the bridge deck. Then, it is connected to the bottom of the hanging basket using a precision-rolled threaded steel rod.

[0068] Then assemble the facade protection, and engage the sleeve post 22 in the middle of the clamping plate 21 with the grooves opened on the two adjacent grid plates. Pull the clamping plate 21 outward so that the movement of the clamping plate 21 drives the connecting sleeve 222 to move along the surface of the support post 221, so that the limiting plate 224 on the support post 221 moves in the inner wall of the limiting groove 225 of the connecting sleeve 222, thereby stretching the compression spring 223 to deform and generate elastic force, and making the positioning stud 23 align with the corresponding hole on the grid plate. After releasing the clamping plate 21, under the elastic force of the compression spring 223, the clamping plate 21 clamps the surface of the grid plate, and the positioning stud 23 is inserted into the hole, and the locking block 236 squeezes the telescopic spring 235.

[0069] Then, rotating the handle 231 causes the positioning stud 23 to rotate. The rotation of the positioning stud 23 causes the threaded block 233 to move along the inner wall of the sleeve 232 on its surface. The movement of the locking block 236 along the inner wall of the groove 237 causes the telescopic spring 235 to deform. When the threaded block 233 moves to a certain position, the elastic force of the telescopic spring 235 causes the locking block 236 to engage with the slot 238.

[0070] After the single-sided facade protection is assembled, it is hoisted to the top of the base using a tower crane or a bridge deck winch. The columns on the facade protection are welded to the base protection. The vertically placed single-sided facade protection are aligned with the holes on the grid plate through the through holes 102 on the L-shaped steel plate 101. The T-shaped sliding column 103 is inserted into the grid plate through the through holes 102, with one end protruding from the grid plate. Then, the rotating rod 104 is rotated, which drives the gear 106 to rotate. The rotation of the gear 106 drives... The movable connecting rod 112 moves along the inner wall of the arc groove 109. The movement of the connecting rod 112 drives the T-shaped sliding rod 111 to move along the inner wall of the sliding groove 110 of the mounting plate 108. The movement of the T-shaped sliding rod 111 causes it to move along the inner wall of the expansion groove 113, which facilitates contact with the surface of the grid plate. Thus, the L-shaped steel plate 101 and the grid plate are connected together through the T-shaped sliding column 103, thereby connecting the various sides of the facade protection together. At the same time, it can be quickly assembled and disassembled without the aid of tools, improving construction efficiency.

[0071] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
