Description

Technical Field

[0001] This application relates to the field of building formwork construction technology, and in particular to a simple reinforcement device for wall and column formwork and its construction method. Background Technology

[0002] Wall and column formwork is a temporary mold used to shape and ensure the size and position of concrete walls and columns during pouring. Commonly used forms include wooden formwork, steel formwork, and aluminum alloy formwork. Current technology primarily uses a combination of joists, hoops, tie bolts, and diagonal braces for fixing. Vertical and horizontal ribs, along with through-column tie bolts, bear lateral pressure. Diagonal braces and limiting measures ensure overall stability and prevent bulging and displacement. Furthermore, reinforcement spacing is rationally set according to the cross-sectional dimensions and height.

[0003] For example, patent application CN121205382A discloses a sleeve threaded rod, a template support device, and a template support system. The sleeve threaded rod includes a first sleeve, a second sleeve, threaded steel bars, and connecting threaded rods. The template support device includes a reinforcement device, which includes steel sections in reinforced concrete components, sleeve threaded rods, and a fixed template. The sleeve threaded rods include a first sleeve, a second sleeve, threaded steel bars, and connecting threaded rods, which are symmetrically arranged on both sides of the steel sections. The connecting threaded rods of the sleeve threaded rods are fixed to the fixed template. The template support system includes a template support device and tie bolts located outside the template support device, wherein the tie bolts are fitted with PVC sleeves on their outer sides.

[0004] However, when using the aforementioned formwork support system to reinforce the formwork, it is necessary to sequentially complete the following steps: connecting the threaded rebar to the first sleeve on the steel section, tightening the second sleeve, and aligning and locking the connecting bolts with the formwork. When the wall column is high, operators need to erect scaffolding or other operating platforms and complete the precise connection and tightening of multiple sets of sleeves, threaded rebar, and connecting bolts at height. In wall column pouring scenarios where the requirements for formwork reinforcement force and fixing method are not high and the wall column height is relatively high, the aforementioned formwork support system has many components, is inconvenient to operate, and has complicated procedures. Furthermore, it requires the erection of scaffolding or other high-altitude operating platforms, resulting in low construction efficiency and certain safety risks associated with wall column formwork reinforcement. Summary of the Invention

[0005] The purpose of this application is to provide a simple reinforcement device for wall and column formwork and its construction method, which solves the problems in related technologies such as the large number of formwork support system components, inconvenient operation, complicated procedures, and the need to erect scaffolding and other high-altitude operation platforms, resulting in low construction efficiency and certain safety risks in the reinforcement of wall and column formwork.

[0006] Firstly, the simple reinforcement device for wall and column formwork provided in this application adopts the following technical solution: A simple reinforcement device for wall column formwork includes: The reinforcement component includes a support and a clamping plate. The clamping plate consists of two plates that can be opened and closed on the support. The two clamping plates are used to fix and hold the wall column template on both sides. A movable support frame, wherein the movable support frame is equipped with wheels at its bottom; A lifting seat is slidably mounted on the movable support along the vertical direction. The movable support is provided with a lifting drive component for driving the lifting seat to move vertically. The support and the lifting seat can be detachably connected. The tensioning and opening drive mechanism has a linkage component on the support that is connected to the clamping plate. The tensioning and opening drive mechanism and the linkage component can be detachably connected, and the linkage component can drive the two clamping plates to move in opposite directions or in opposite directions.

[0007] Optionally, the linkage component includes a slide table and a screw. The slide table is slidably mounted on the support. When the slide table slides relative to the support, it can drive the two clamping plates to move in opposite directions or back to back. The slide table is provided with a screw hole. The screw is rotatably mounted on the support and is screwed to the slide table through the screw hole. The opening and closing drive mechanism can be detachably connected to the screw and drive the screw to rotate.

[0008] Optionally, the linkage assembly further includes a swing arm and a connecting rod. The swing arm is hinged to the support. Two sets of swing arms are symmetrically arranged, each set including two parallel swing arms. The two clamping plates are respectively hinged to the two sets of swing arms. The two ends of the connecting rod are respectively hinged to the slide and the clamping plate.

[0009] Optionally, the opening and closing drive mechanism includes a rotating shaft and a power input component. The end of the screw is provided with a sleeve. The rotating shaft is rotatably mounted on the lifting seat in a horizontal direction. The rotating shaft is provided with a screwdriver head that can be inserted into the sleeve. The power input component is mounted on the movable bracket and is connected to the rotating shaft through a torque transmission assembly to drive the rotating shaft to rotate.

[0010] Optionally, the torque transmission assembly includes a main shaft and an intermediate shaft, which are rotatably mounted on the lifting seat along a vertical axis. The intermediate shaft is connected to the rotating shaft. The main shaft is connected to the intermediate shaft through a one-way drive component. The one-way drive component is used to restrict the main shaft to drive the intermediate shaft to rotate only in a first direction. When the intermediate shaft rotates in the first direction, it can drive the two clamping plates to move in opposite directions. The power input component is connected to the main shaft through a telescopic shaft assembly and is used to drive the main shaft to rotate.

[0011] Optionally, the torque transmission assembly further includes an anti-rotation component, which is disposed on the lifting seat and acts on the intermediate shaft. The anti-rotation component is used to prevent the intermediate shaft from rotating in a second direction, which is the opposite direction to the first direction.

[0012] Optionally, a locking mechanism is also included, the locking mechanism including a locking tongue, the lifting seat having a sliding groove, the support being able to slide and engage with the lifting seat through the sliding groove, the support having a locking groove, the locking tongue being retractable on the lifting seat and able to extend into the sliding groove, the locking tongue being able to engage with the locking groove after the support is engaged in the sliding groove, thereby fixing the support to the lifting seat.

[0013] Optionally, the locking mechanism further includes a rotating drum, which is rotatably mounted on the lifting seat and sleeved on the outside of the main shaft. The main shaft is connected to the rotating drum through a one-way transmission assembly. The one-way transmission assembly is used to drive the rotating drum to rotate synchronously when the main shaft rotates in the second direction. When the rotating drum rotates in the second direction, it can drive the locking tongue to slide away from the slide groove through the actuating component.

[0014] Optionally, the locking mechanism further includes a locking spring and a return spring. The actuating component includes a drive shaft and a release block. The release block is slidably disposed on the lifting seat. The latch is slidably connected to the release block. The drive shaft is rotatably disposed on the lifting seat. Both ends of the drive shaft are respectively connected to the rotating drum and the release block. When the rotating drum rotates in the second direction, it can drive the release block to slide away from the slide groove through the drive shaft, and drive the latch to move synchronously. The return spring is used to push the release block to slide closer to the slide groove, and the locking spring is used to push the latch to slide closer to the slide groove.

[0015] Secondly, the construction method of the simple reinforcement device for wall and column formwork provided in this application adopts the following technical solution: A construction method for a simple reinforcement device for wall and column formwork includes the following steps: S1. Connect the support of the reinforcement component to the lifting seat, and connect the opening and closing drive mechanism to the linkage component on the support; S2. Move the mobile support to one side of the wall column formwork to be reinforced using the walking wheels, and place the two clamping plates on both sides of the wall column formwork respectively; S3. Drive the lifting seat to slide vertically through the lifting drive component, adjust the height of the reinforcement components, and make the two clamping plates correspond to the height position of the wall column formwork that needs to be reinforced; S4. Operate the tensioning and opening drive mechanism to drive the two clamping plates to move in opposite directions through the linkage component until the two clamping plates are clamped and fixed with the wall column formwork; S5. Separate the lifting seat from the support of the reinforcement component, and separate the opening and closing drive mechanism from the linkage component on the support. Remove the moving bracket to complete the simple reinforcement of the wall column formwork.

[0016] In summary, this application includes at least the following beneficial technical effects: When reinforcing wall and column formwork using the device of this application, after moving the movable support to a predetermined position, the lifting seat is driven to slide vertically by the lifting drive component to adjust the height of the reinforcing component. Then, the two clamping plates are driven to clamp and fix the wall and column formwork by the tensioning drive mechanism and the linkage component. Finally, the lifting seat is separated from the support of the reinforcing component, and the tensioning drive mechanism is separated from the linkage component on the support, thus achieving simple reinforcement of the wall and column formwork. Through the reasonable cooperation of the reinforcing component, movable support, lifting seat, tensioning drive mechanism, and linkage component, this device can complete the reinforcement by simply assembling, moving, lifting, and clamping operations. Operators can complete all operations such as lifting and clamping on the ground without the need to erect scaffolding or other high-altitude work platforms, thereby greatly simplifying the operation process, reducing the difficulty of operation for operators, significantly improving the overall construction efficiency, and reducing the safety risks during operation.

[0019] The following is in conjunction with the appendix Figure 1 - Appendix Figure 10 This application will be described in further detail below.

[0020] This application discloses a simple reinforcement device for wall and column formwork and its construction method.

[0021] A simple reinforcement device for wall column formwork includes a reinforcement component 10, a movable support 20, a lifting seat 30, a tensioning drive mechanism 50, and a locking mechanism 60.

[0022] Reference Figures 1 to 4 The reinforcement component 10 includes a support 11 and a clamping plate 12. There are two clamping plates 12, which can be opened and closed on the support 11. The two clamping plates 12 are used to fix and clamp the two sides of the wall column template 70. The support 11 is provided with a linkage component connected to the clamping plate 12. The linkage component can drive the two clamping plates 12 to move towards each other or away from each other.

[0023] Specifically, the linkage assembly includes a slide table 13, a screw 14, a swing arm 15, and a connecting rod 16. The swing arm 15 is hinged to the support 11 via a first hinge shaft 151. Two sets of swing arms 15 are symmetrically arranged, each set including two parallel swing arms 15. Two clamping plates 12 are respectively hinged to the two sets of swing arms 15 via a second hinge shaft 121. The two ends of the connecting rod 16 are respectively hinged to the slide table 13 and the clamping plates 12 via a third hinge shaft 161 and a fourth hinge shaft 162.

[0024] The support 11 is provided with a guide rod 111, and the slide 13 is slidably sleeved on the guide rod 111 of the support 11. When the slide 13 slides relative to the support 11, it can drive the two clamping plates 12 to move in opposite directions or back to back. The slide 13 is provided with a screw hole, and the screw 14 is rotatably mounted on the support 11 and screwed to the slide 13 through the screw hole. When the screw 14 rotates, it can drive the slide 13 to slide along the guide rod 111, and then drive the two clamping plates 12 to move in opposite directions or back to back through the connecting rod 16 and the swing arm 15.

[0025] The movable support 20 has wheels 21 at its bottom, which are common brake casters in the prior art. The movable support 20 has a vertical column 22, and the lifting seat 30 has a guide sleeve 35. The lifting seat 30 slides vertically onto the vertical column 22 via the guide sleeve 35. The movable support 20 has a lifting drive component 40 for driving the lifting seat 30 to move vertically. The lifting drive component 40 includes a first worm gear reducer 41, sprockets 42, and a chain 43. Two sets of sprockets 42 are rotatably mounted on the movable support 20. The chain 43 is wound around the two sets of sprockets 42. The lifting seat 30 is fixedly connected to the chain 43. The first worm gear reducer 41 is fixedly mounted on the movable support 20. The input end of the first worm gear reducer 41 has a first crank 411, and the output end of the first worm gear reducer 41 is connected to one of the sprockets 42.

[0026] The lifting seat 30 is provided with a sliding groove 31, and the support 11 is provided with a protruding rib 113. The shape of the sliding groove 31 is adapted to the protruding rib 113. The support 11 can slide and engage with the lifting seat 30 through the sliding groove 31 to achieve a separable connection between the support 11 and the lifting seat 30.

[0027] Reference Figures 3 to 8 The opening and closing drive mechanism 50 can be detachably connected to the screw 14 of the linkage component and drive the screw 14 to rotate, thereby driving the two clamping plates 12 to move in opposite directions or back to back through the linkage component. In this embodiment, the specific structure of the opening and closing drive mechanism 50 and its specific connection relationship with the screw 14 are as follows: The opening and closing drive mechanism 50 includes a rotating shaft 51 and a power input component. The end of the screw 14 is provided with a sleeve 141, which can be an internal hexagonal sleeve. The rotating shaft 51 is rotatably mounted on the lifting seat 30 in a horizontal direction. The rotating shaft 51 is provided with a screwdriver head 511 that can be inserted into the sleeve 141 and is adapted in shape. The power input component is mounted on the movable bracket 20 and is connected to the rotating shaft 51 through a torque transmission assembly to drive the rotating shaft 51 to rotate. The torque transmission assembly includes a main shaft 52, an intermediate shaft 53, and an anti-rotation component. The main shaft 52 and the intermediate shaft 53 are rotatably mounted on the lifting seat 30 in a vertical coaxial manner. The intermediate shaft 53 is connected to the rotating shaft 51 through a first bevel gear pair 531.

[0028] The main shaft 52 is connected to the intermediate shaft 53 via a one-way drive component. Specifically, the one-way drive component includes a ratchet shaft 54 ​​and a compression spring 55. The main shaft 52 is provided with a torque transmission protrusion 521. The ratchet shaft 54 ​​is slidably sleeved on the torque transmission protrusion 521. The intermediate shaft 53 is provided with a first end face ratchet 532. The ratchet shaft 54 ​​is provided with a second end face ratchet 541 that can mesh with the first end face ratchet 532. The compression spring 55 is sleeved on the outside of the ratchet shaft 54. The two ends of the compression spring 55 abut against the second end face ratchet 541 and the lifting seat 30, respectively. The compression spring 55 is used to drive the first end face ratchet 532 and the second end face ratchet 541 to maintain an axial meshing state. The ratchet teeth on the two ratchets are one-way helical teeth. When rotating in the forward direction, they engage with each other to achieve torque transmission. When rotating in the reverse direction, the helical surfaces of the ratchet teeth slide against each other to achieve overtaking or disengagement.

[0029] The unidirectional drive component is used to restrict the spindle 52 to drive the intermediate shaft 53 to rotate only in the first direction. In this embodiment, the first direction is set to the clockwise direction. When the intermediate shaft 53 rotates in the first direction, it can drive the two clamping plates 12 to move in opposite directions.

[0030] The power input component is connected to the main shaft 52 via the telescopic shaft assembly 56 and is used to drive the main shaft 52 to rotate. Specifically, the telescopic shaft assembly 56 is composed of multiple shafts 561 with different outer diameters coaxially sleeved together. The multiple shafts 561 can slide relative to each other axially to realize the overall length extension and retraction adjustment. A limiting structure is provided between adjacent shafts 561 to prevent axial separation. In this embodiment, the limiting structure includes a limiting groove 562 provided on adjacent inner shafts 561 and a limiting pin 563 provided on adjacent outer shafts 561. The limiting pin 563 slides and engages with the limiting groove 562. The outer contour of the cross section of the shaft 561 and the inner hole of the cooperating shaft 561 can be set as a regular polygon or spline shape to realize torque transmission. The power input component is a second worm gear reducer 57, which is fixed on the movable bracket 20. The input end of the second worm gear reducer 57 is provided with a second crank 571. The upper end of the telescopic shaft assembly 56 is fixedly connected to the main shaft 52, and the lower end of the telescopic shaft assembly 56 is fixedly connected to the output end of the second worm gear reducer 57.

[0031] An anti-rotation component is mounted on the lifting seat 30 and acts on the intermediate shaft 53. Specifically, the anti-rotation component includes a first pawl 58 and a first spring plate 59. A first ratchet 533 is provided on the intermediate shaft 53. The first pawl 58 is rotatably mounted on the lifting seat 30 via a first pin 581 and can engage with the first ratchet 533. One end of the first spring plate 59 is fixedly mounted on the lifting seat 30, and the first spring plate 59 abuts against the first pawl 58, so that the first pawl 58 always has a tendency to swing towards the first ratchet 533 and maintain engagement. The anti-rotation component is used to prevent the intermediate shaft 53 from rotating in a second direction, which is the opposite direction to the first direction, i.e., counterclockwise.

[0032] Reference Figure 4 , Figure 7 , Figure 9 and Figure 10 After the support 11 is engaged with the lifting seat 30, the locking and unlocking of the support 11 and the lifting seat 30 can be controlled by the locking mechanism 60. In this embodiment, the specific structure of the locking mechanism 60 and its specific connection relationship with the support 11 and the lifting seat 30 are as follows: The locking mechanism 60 includes a locking tongue 61, a rotating cylinder 62, a locking spring 65, and a return spring 66. The support 11 is provided with a locking groove 112. The locking tongue 61 is telescopically mounted on the lifting seat 30 and can extend into the sliding groove 31. After the support 11 is engaged with the locking groove 112, the locking tongue 61 can lock the support 11 to the lifting seat 30.

[0033] The rotating drum 62 is rotatably mounted on the lifting seat 30 and sleeved on the outside of the main shaft 52. The main shaft 52 is connected to the rotating drum 62 through a one-way transmission assembly. The one-way transmission assembly is used to drive the rotating drum 62 to rotate synchronously when the main shaft 52 rotates in the second direction. Specifically, the one-way transmission assembly includes a second pawl 63 and a second spring plate 64. The main shaft 52 is provided with a second ratchet 522. The second pawl 63 is rotatably mounted on the rotating drum 62 through a second pin 631 and can engage with the second ratchet 522. One end of the second spring plate 64 is fixedly mounted on the rotating drum 62 and abuts against the second pawl 63, so that the second pawl 63 always has the tendency to swing in the direction of the second ratchet 522 and maintain engagement.

[0034] When the drum 62 rotates in the second direction, the locking tongue 61 can be driven by the actuating component to slide away from the slide groove 31, thus disengaging it from the locking groove 112 and completing the unlocking. The actuating component includes a drive shaft 67, a release block 68, and a slider 69. The lifting seat 30 is provided with a first guide groove 32 and a second guide groove 33. The locking tongue 61 and the release block 68 are slidably disposed in the first guide groove 32 and the second guide groove 33, respectively. The locking tongue 61 and the release block 68 are slidably connected. Specifically, the locking tongue 61 is provided with a connecting rod 611, which slides through the release block 68. The connecting rod 611 is provided with a shoulder 612 for preventing the connecting rod 611 from disengaging from the release block 68.

[0035] A drive shaft 67 is rotatably mounted on a lifting seat 30. Both ends of the drive shaft 67 are connected to a rotating drum 62 and a release block 68, respectively. Specifically, one end of the drive shaft 67 is connected to the rotating drum 62 via a second bevel gear pair 671, and the other end of the drive shaft 67 is equipped with a gear 672. A guide rail 34 is provided on the lifting seat 30, and a slider 69 is slidably mounted on the guide rail 34. The slider 69 is equipped with a rack 691 that meshes with the gear 672. The release block 68 is equipped with a column 681, which is fixedly connected to the slider 69. When the rotating drum 62 rotates in the second direction, the drive shaft 67 drives the release block 68 to slide away from the slide groove 31, and simultaneously moves the locking tongue 61 to unlock the device.

[0036] The reset spring 66 is sleeved on the outside of the column 681. The two ends of the reset spring 66 abut against the end faces of the unlocking block 68 and the second guide groove 33, respectively. The reset spring 66 is used to push the unlocking block 68 to slide towards the slide groove 31, so as to push the unlocking block 68 to reset.

[0037] The locking spring 65 is sleeved on the outside of the connecting rod 611. The two ends of the locking spring 65 abut against the end faces of the locking tongue 61 and the first guide groove 32, respectively. The locking spring 65 is used to push the locking tongue 61 to slide towards the slide groove 31. When the unlocking block 68 is reset, the locking tongue 61 is reset under the action of the locking spring 65, which facilitates the next locking. The locking tongue 61 can be set as a wedge shape. The wedge structure of the locking tongue 61 makes it easy for the support 11 to be inserted into the slide groove 31. The support 11 will squeeze the locking tongue 61 to automatically retract it without manual operation.

[0038] Based on the aforementioned simplified reinforcement device for wall and column formwork, this embodiment provides a construction method. After the wall and column formwork 70 is assembled, multiple sets of reinforcement components 10 are used to reinforce the formwork 70. The wall and column formwork 70 involved in this embodiment is a conventional building wall and column formwork structure in the prior art. Its specific structure includes components such as a panel 71, vertical ribs 72, and horizontal ribs 73. The panel 71 serves as the reference surface for concrete forming. The vertical ribs 72 are arranged vertically along the outer wall of the panel 71, and the horizontal ribs 73 are arranged horizontally along the outer side of the vertical ribs 72. The vertical ribs 72 and horizontal ribs 73 cooperate to enhance the overall rigidity of the wall and column formwork 70 and prevent deformation of the formwork during concrete pouring. The structure, material, and connection method of the aforementioned wall and column formwork 70 are all prior art known in the field of building construction and are not innovative points of this application. This application does not improve its structure itself, but only uses it as the object to be reinforced. The scope of protection of this application is limited only to the simplified reinforcement device for wall and column formwork and its construction method, and does not include the aforementioned prior art wall and column formwork 70 itself.

[0039] The construction method of the simple reinforcement device for wall and column formwork in this embodiment includes the following steps: S1. Fully engage the support 11 of the reinforcing component 10 into the slide groove 31 of the lifting seat 30. During the engagement process, the support 11 presses against the wedge-shaped surface of the locking tongue 61, causing the locking tongue 61 to automatically retract into the first guide groove 32. After the support 11 is engaged, the locking tongue 61 is engaged into the locking groove 112 of the support 11 under the action of the locking spring 65, thus completing the locking of the support 11 and the lifting seat 30 and fixing the support 11 of the reinforcing component 10 to the lifting seat 30.

[0040] After the support 11 is fully inserted into the slide groove 31, the screwdriver head 511 is simultaneously inserted into the sleeve 141, connecting the opening and closing drive mechanism 50 with the linkage component on the support 11.

[0041] S2. Move the mobile support 20 to one side of the wall column template 70 to be reinforced by using the walking wheels 21, and place the two clamping plates 12 on both sides of the wall column template 70 respectively.

[0042] S3. The lifting seat 30 is driven to slide vertically by the lifting drive component 40. Specifically, the operator rotates the first crank 411, which drives the first worm gear reducer 41 to work. The output end of the first worm gear reducer 41 drives one set of sprockets 42 to rotate. The sprockets 42 drive the chain 43 to rotate, and the chain 43 drives the lifting seat 30 to move vertically. This adjusts the height of the reinforcing component 10 so that the two clamping plates 12 correspond to the height position of the wall column template 70 that needs to be reinforced. During the vertical movement of the lifting seat 30, the telescopic shaft assembly 56 extends and retracts to adapt to the height change of the lifting seat 30.

[0043] S4. Operate the tensioning drive mechanism 50, which drives the two clamping plates 12 to move in opposite directions through the linkage component until the two clamping plates 12 are clamped and fixed with the wall column template 70. Specifically, the operator rotates the second crank 571 to drive the second worm gear reducer 57 to work. The output end of the second worm gear reducer 57 drives the telescopic shaft assembly 56 to rotate, and the telescopic shaft assembly 56 drives the main shaft 52 to rotate in a clockwise direction (first direction).

[0044] When the main shaft 52 rotates, it drives the ratchet shaft 54 ​​to rotate synchronously through the torque transmission head 521. Under the action of the compression spring 55, the second end face ratchet 541 meshes with the first end face ratchet 532 on the intermediate shaft 53, transmitting torque to the intermediate shaft 53, causing the intermediate shaft 53 to rotate synchronously clockwise. The intermediate shaft 53 drives the rotating shaft 51 to rotate through the first bevel gear pair 531. The rotating shaft 51 drives the screw 14 to rotate through the cooperation of the screwdriver head 511 and the sleeve 141.

[0045] When the screw 14 rotates, it engages with the screw hole on the slide table 13, driving the slide table 13 to slide along the guide rod 111 of the support 11 towards the wall column template 70; the slide table 13 drives the two clamping plates 12 to move smoothly in opposite directions through the connecting rod 16 and the swing arm 15 until the two clamping plates 12 are tightly attached to and clamped to the transverse rib 73 of the wall column template 70.

[0046] S5. Separate the lifting seat 30 from the support 11 of the reinforcing component 10, and separate the opening and closing drive mechanism 50 from the linkage component on the support 11. Specifically, rotate the second crank 571 in the opposite direction to drive the main shaft 52 to rotate in the counterclockwise direction (second direction); at this time, the second end face ratchet 541 of the one-way drive component slides against the first end face ratchet 532, the intermediate shaft 53 remains stationary under the action of the first pawl 58 and the first ratchet 533 (the clamping plate 12 remains clamped), and at the same time, the second pawl 63 of the one-way transmission component engages with the second ratchet 522 on the main shaft 52 under the action of the second spring plate 64, driving the rotating drum 62 to rotate synchronously counterclockwise.

[0047] When the drum 62 rotates, it drives the transmission shaft 67 to rotate through the second bevel gear pair 671. The transmission shaft 67 meshes with the rack 691 on the slider 69 through the gear 672, causing the slider 69 to slide along the guide rail 34 away from the slide groove 31. The slider 69 drives the unlocking block 68 to slide along the second guide groove 33 through the column 681. The unlocking block 68 drives the locking tongue 61 to overcome the elastic force of the locking spring 65 through the connecting rod 611 and exit from the locking groove 112 of the support 11, releasing the lock between the support 11 and the lifting seat 30.

[0048] Pull the movable support 20 outward to separate the lifting seat 30 from the support 11. At the same time, the screw head 511 disengages from the sleeve 141 of the screw 14, separating the opening and closing drive mechanism 50 from the linkage component.

[0049] Remove the movable support 20 to complete the clamping and fixing of a set of reinforcement components 10 to the wall column template 70. Then repeat the above steps to clamp and fix multiple sets of reinforcement components 10 to the side of the wall column template 70 one by one, thus completing the simple reinforcement of the wall column template 70. Multiple sets of reinforcement components 10 are arranged in pairs along the vertical direction.

[0050] It should be noted that for the lower part of the wall column formwork 70 (i.e., the height range where the operator can operate directly without the aid of climbing equipment), when carrying out reinforcement work, the reinforcement component 10 can be used directly to clamp and fix it, without the need for the moving bracket 20, lifting seat 30, opening and closing drive mechanism 50 and locking mechanism 60 in this application.

[0051] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
