Description

Technical Field

[0001] The present invention relates to the technical field of building (structure) construction, in particular to a rapid support system. Background Art

[0002] Construction engineering supports are structures used to support the pouring of concrete columns during the construction of buildings (structures). Their main function is to tie the column's steel cage before pouring, set up formwork outside the tied steel cage, and then use the support system to support the formwork to ensure that it does not deform or collapse during the pouring process.

[0003] However, the existing support systems for prefabricated large-span multi-story building projects mostly use large column caps, which have many disadvantages. Although the large column cap structure can solve the problem of beam-column overlap nodes and facilitate on-site construction, it requires the use of special molds, and the spacing between the steel bars inside the column cap is small, making it difficult to tie and hoist. In addition, there is the problem of difficulty in disassembly after pouring. More importantly, the cost of large column caps is higher than that of ordinary columns, and the column caps have no other function after the beam is installed. After pouring, when the beam-column node reaches the strength requirement, the excess column caps are exposed to the outside, affecting the overall appearance. Therefore, there is an urgent need for a system that can eliminate the large column cap structure and achieve rapid support at the same time.

[0004] To this end, we propose a rapid support system. Summary of the Invention

[0005] The purpose of the present invention is to provide a rapid support system to solve the above-mentioned deficiencies in the prior art.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a rapid support system comprising a main column, a side column and a detachable column, wherein a cavity is formed between the mutually adjacent surfaces of the main column, the side column and the detachable column to support the concrete column;

[0007] The rapid support system further comprises:

[0008] A driving mechanism is provided on the main column, and a mounting base is installed on the bottom of the main column. A cavity is formed in the interior of the mounting base and the side column. A pulling mechanism is provided in the cavity to connect the driving mechanism with a pulling arm. The pulling arm is fixedly connected to the detachable column. The pulling mechanism is used by the driving mechanism to pull the detachable column so that it approaches the surface of the concrete column.

[0009] A wedge block 2 is fixedly arranged on the inner wall surface of the side column, and the side column is slidably arranged on the end surface of the mounting base. When the driving mechanism pulls the pulling mechanism, the pulling mechanism contacts the wedge block 2 to make the side column close to the surface of the concrete column.

[0010] As a further description of the above technical solution: the main column, side column and detachable column are respectively connected with telescopic end one, telescopic end two and telescopic end three, and the telescopic end one, telescopic end two and telescopic end three are all provided with supporting angle pieces, wherein the outer surface of the telescopic end two is fixed with a plug-in groove, and the outer surfaces of the telescopic end one and the telescopic end two are respectively fixed with an active rod and a driven rod that are slidably engaged in the plug-in groove, and the telescopic end one is inserted into the end of the main column and connected to the driving mechanism, through which the telescopic end one, telescopic end two and telescopic end three can rise simultaneously.

[0011] As a further description of the above technical solution: the rapid support system also includes a rack installed on the telescopic end one through the telescopic plate one and a gear installed on the main column through the telescopic plate two, and the gear and the rack are meshed. The telescopic part of the telescopic plate two is connected to the side column through the mounting arm. When the side column approaches the central concrete column and the supporting angle piece contacts the concrete column, the rotation axis position of the gear is set opposite to the gap between the side column and the concrete column.

[0012] As a further description of the above technical solution: an auxiliary reinforcement mechanism is provided on the surface of the axial position of the gear. When the detachable column approaches the concrete column and the supporting angle piece on the third telescopic end thereof contacts the concrete column, the auxiliary reinforcement mechanism is used to reinforce the action of the supporting angle piece contacting the concrete column.

[0013] As a further description of the above technical solution: the auxiliary reinforcement mechanism includes a screw rod 2 that is rotatably set on the telescopic plate 2 and connected to the gear through a connecting part, and a reinforcement plate threadedly installed on the screw rod 2. When the side column approaches the concrete column and the supporting angle piece on the telescopic end 2 contacts the concrete column, the outer peripheral side of the reinforcement plate contacts the surface of the concrete column.

[0014] As a further description of the above technical solution: the auxiliary reinforcement mechanism also includes an extension end fixedly arranged on the surface of the detachable column, and the side surface of the extension end close to the reinforcement plate is on the same plane as the side surface of the concrete column, and when the supporting angle piece on the telescopic end is attached to the surface of the concrete column, the gap between the extension end and the concrete column is smaller than the width of the reinforcement plate.

[0015] As a further description of the above technical solution: a clamping plate is fixedly provided on the extension end. After the reinforcing plate moves to the end of the extension end and rotates to fit into the clamping plate, the connecting part separates the gear from the screw rod, and the screw rod stops rotating.

[0016] As a further description of the above technical solution: the rapid support system also includes a limiting mechanism, which is arranged between the detachable column and the pulling mechanism. When the supporting angle piece on the telescopic end three contacts the surface of the concrete column, the limiting mechanism is used to stop the pulling mechanism from pulling the detachable column.

[0017] As a further description of the above technical solution: a vertical rod is provided on the extension end through spring three, and a pressure ring and a wedge block one are respectively provided on the top port and the bottom port of the vertical rod. When the screw rod two rotates in the opposite direction, the reinforcing plate resists the pressure ring to move the vertical rod downward.

[0018] As a further description of the above technical solution: the limiting mechanism is provided with an inclined plate through a torsion spring, and the contact position of the inclined plate with the pulling arm through the torsion spring is provided on the same side of the wedge block 1 and the extrusion block.

[0019] In the above technical solution, the rapid support system provided by the present invention has the following beneficial effects:

[0020] 1. This rapid support system, through the design of main columns, side columns, and removable columns, can quickly create support space for the external formwork of concrete columns. The provision of removable columns, in particular, makes installation of the support system more flexible and convenient. During installation, simply assemble the main columns, side columns, and removable columns in a specific order and adjust them using the drive mechanism to achieve stable support for the concrete columns. This design significantly improves installation efficiency and shortens construction time.

[0021] 2. The drive mechanism in this system includes components such as a knob, a worm, lead screw 1, and a worm gear. Turning the knob activates the entire support system. As the knob is turned, the worm rotates the worm gear, which in turn drives lead screw 1 to move up and down. This entire transmission process is automated, eliminating the need for complex manual operations. Furthermore, the ergonomic design of the knob makes operation easier and more labor-saving. Furthermore, turning the knob allows for simultaneous installation and adjustment of both the side columns and the detachable columns, further streamlining the operation process.

[0022] 3. The system also includes an auxiliary reinforcement mechanism. Through the threaded structure of the reinforcement plate and the screw, it automatically reinforces the removable columns after the support angle fittings are attached to the formwork. The outer perimeter of the reinforcement plate contacts the surface of the concrete column, increasing overall strength during pouring and effectively preventing formwork explosion. This automatic reinforcement function, which requires no additional operation, further improves construction efficiency and safety. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0039] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0040] See also Figure 1 - Figure 13 The embodiment of the present invention provides a technical solution: a rapid support system, including a main column 1, a side column 5 and a detachable column 12, wherein a cavity is formed between the surfaces of the main column, the column side column 5 and the detachable column 12 close to each other to support the concrete column. Before pouring the concrete column, the steel cage of the column is tied, and a template is set outside the tied steel cage. The main column 1, the side column 5 and the detachable column 12 are provided to form a space to support the template outside the steel cage. In this way, when the tied steel cage inside is poured through the opening at the top of the template, the main column 1, the side column 5 and the detachable column 12 can support the template to complete the pouring operation of the steel cage. The rapid support system also includes:

[0041] A driving mechanism is provided on the main column 1 and a mounting base 14 is installed on the bottom of the main column 1. A connected cavity is formed inside the mounting base 14 and the side column 5, and a pulling mechanism is provided in the cavity to connect the driving mechanism with the pulling arm 3. The pulling arm 3 is fixedly connected to the detachable column 12, and the pulling mechanism is used to pull the detachable column 12 so that it is close to the surface of the concrete column. It should be noted that the detachable column 12 is connected to the main column 1 through the pulling mechanism. When it is necessary to support the formwork, the main column 1 and the side column 5 without the detachable column 12 are first installed. At this time, the main column 1 and the side column 5 are U-shaped in top view. The main column 1 and the side column 5 are installed through the notch where the detachable column 12 is not installed. After the installation is completed, the detachable column 12 is connected to the pulling mechanism. At this time, the detachable column 12 can be brought close to the concrete column by rotating the driving mechanism.

[0042] A wedge block 2 10 is fixedly mounted on the inner wall surface of the side column 5, and the side column 5 is slidably mounted on the end surface of the mounting base 14. When the driving mechanism pulls the pulling mechanism, the pulling mechanism contacts the wedge block 2 10, causing the side column 5 to approach the surface of the concrete column. When the driving mechanism is rotated, the pulling mechanism pulls the detachable column 12, and the position of the detachable column 12 pulled by the pulling mechanism also moves toward the main column 1, thereby squeezing the wedge block 2 10, so that the side column 5 moves toward the concrete column until the side column 5 and the detachable column 12 are in place. At this time, the main column 1, the side column 5, and the detachable column 12 form a support system to support the internal mold. By providing the detachable detachable column 12, the support system can be quickly installed. During installation, the side column 5 and the detachable column 12 can be installed simultaneously only by the driving mechanism. The installation method is convenient and does not require installation through multiple installation mechanisms, making it easy to use.

[0043] The main column 1, the side column 5 and the detachable column 12 are respectively connected with the telescopic end 1 4, the telescopic end 2 51 and the telescopic end 2 51, and the telescopic end 1 4, the telescopic end 2 51 and the telescopic end 3 13 are all provided with supporting angle pieces 11, wherein the outer surface of the telescopic end 2 51 is fixed with a plug-in groove 71, and the outer surfaces of the telescopic end 1 4 and the telescopic end 2 51 are respectively fixed with an active rod 7 and a driven rod 72 that are slidably engaged in the plug-in groove 71, and the telescopic end 1 4 is inserted into the end of the main column 1 and connected to the driving mechanism, through which the telescopic end 1 4, the telescopic end 2 51 and the telescopic end 3 13 can rise simultaneously. It should be noted that when first installing the main column 1 and the side column 5, the supporting angle piece 11 on the telescopic end 1 4 on the main column 1 should be fitted on the outer surface of the formwork, and then the side column 5 and the detachable column 12 are moved close to the concrete column through the driving mechanism until the supporting angle piece 11 on the top of the telescopic end 1 4, the telescopic end 2 51 and the telescopic end 3 13 is fitted on the formwork surface outside the concrete column, and the telescopic end 1 4, the telescopic end 2 51 and the telescopic end 3 13 are close to each other while driving the top supporting angle piece 11 to rise until the top surface of the supporting angle piece 11 is at the same height as the outer formwork of the concrete column, and then the driving mechanism is stopped. At this time, the installation of the support system is completed, and each supporting angle piece 11 is not only fitted on the concrete column On the outer surface of the formwork, and also at the highest point of the formwork, a plurality of support angle pieces 11 that fit the surface of the formwork can not only support the formwork, but also increase the support area of the beam when the beam is installed with the concrete column, thereby facilitating the installation of the beam. In order to further improve the effect of the installation of the beam, pressure sensors can be installed at the contact positions of the support angle pieces 11 and the telescopic end 1 4, the telescopic end 2 51 and the telescopic end 3 13. When the beam is installed, the pressure can be detected. When the pressure value exceeds the requirement, the pressure sensor alarms. At this time, the beam can be supported by an auxiliary support mechanism to prevent safety accidents. The auxiliary support mechanism can be a scissor fork support structure or a multi-link telescopic support mechanism, both of which are based on existing technologies and will not be described in detail.

[0044] In one embodiment of the present invention, the driving mechanism includes a screw rod 22 rotatably disposed within the main column 1, and a knob 2 and a worm 21 fixedly disposed at both ends of the screw rod 22. The worm 21 is engaged with a worm gear 23 rotatably disposed on the inner wall surface of the mounting base 14, and the end of the telescopic end 4 inserted into the main column 1 is threadedly connected to the screw rod 22. When the knob 2 is turned, the screw rod rotates, thereby causing the telescopic end 4 threadedly connected to the screw rod to move upward, thereby causing the telescopic end 2 51 and the telescopic end 3 13 to move upward. At this time, the multiple support angle pieces 11 move upward until the multiple support angle pieces 11 move to the highest point of the concrete column.

[0045] In another embodiment of the present invention, the pulling mechanism includes a basket bolt 31 rotatably arranged on the rotating axis surface of the worm gear 23 and a screw rod 32 threadedly arranged on the basket bolt 31, a sliding plate 37 is slidably arranged on the inner surface of the mounting base 14, and a vertical plate 34 and a connecting rod 36 are fixedly arranged on the sliding plate 37, and a pulling ring 33 is fixed on the outer peripheral surface of the screw rod 32, and the pulling ring 33 abuts and slidably provides a hook rod 38 whose one end is fixed on the vertical plate 34, and a polygonal column 35 is movably inserted on the end of the screw rod 32, and the polygonal column 35 is inserted into the corresponding through hole opened on the vertical plate 34, and a hole corresponding to the connecting rod 36 is opened on the pulling arm 3. After the main column 1 and the side column 5 are installed around the external formwork of the concrete column, when the detachable column needs to be installed, the connecting rod 36 is inserted into the hole opened on the pulling arm 3, and then the knob 2 is rotated by a tool to make the screw rod The worm gear 23 is driven by the worm 21 at the bottom to rotate the worm gear 23, thereby causing the basket bolt 31 to rotate. It should be noted here that the polygonal column 35 on the end of the screw rod 32 can only slide on the screw rod 32, and cannot rotate with the screw rod 32. This connection method can be a sliding connection, which is an existing connection method. The details will not be repeated again. In this way, since the polygonal column 35 is inserted into the corresponding through hole on the vertical plate 34, the screw rod 32 cannot rotate at this time. At this time, the screw rod 32 will be driven by the basket bolt 31 to move toward the direction close to the main column 1, so that the pulling ring 33 pulls the hook rod 38 to make the connecting rod 36 on the sliding plate 37 pull the pulling arm 3 toward the direction close to the main column 1, thereby causing the detachable column 12 to move toward the direction close to the outer formwork of the concrete column until the supporting angle piece 11 on the telescopic end three 13 is against the surface of the outer formwork of the concrete column.

[0046] When the sliding plate 37 moves toward the main column 1, the sliding plate 37 contacts the wedge block 2 10. The sliding plate 37 squeezes the wedge block 2 10, causing the side column 5 to move toward the template outside the concrete column until the supporting angle piece 11 on the top of the telescopic end 2 51 contacts the surface of the concrete column external template. At this time, the support of the concrete column external template is achieved through the supporting angle pieces 11 on the main column 1, the side column 5 and the detachable column 12. This process only requires simple installation and can be completed by turning the knob 2 with a tool. It is convenient to operate and easy to use.

[0047] The rapid support system also includes a rack 61 mounted on the telescopic end 1 4 through the telescopic plate 1 6 and a gear 63 mounted on the main column 1 through the telescopic plate 2 62, and the gear 63 is meshed with the rack 61. The telescopic portion of the telescopic plate 2 62 is connected to the side column 5 through the mounting arm 64. When the side column 5 approaches the central concrete column and the supporting angle piece 11 contacts the concrete column, the rotation axis position of the gear 63 is set opposite to the gap between the side column 5 and the concrete column. When the knob 2 is turned by the tool, the telescopic end 14 drives the telescopic plate 16 to move upward, and the rack 61 moves upward, driving the gear 63 to rotate. When the knob 2 is rotated by the tool, the sliding plate 37 will contact the wedge block 2 10, and the side column 5 is now close to the concrete column, so that the telescopic plate 1 6 and the telescopic plate 2 62 are shortened by the mounting arm 64, so that the rack 61 and the gear 63 can move with the movement of the side column 5, and the position of the rack 61 and the gear 63 is automatically adjusted until the supporting angle piece 11 on the side column 5 contacts the template surface outside the concrete column. At this time, the position adjustment of the side column 5 is completed, and the positions of the rack 61 and the gear 63 are fixed at the same time.

[0048] It should be noted that, when the side column 5 moves, in order to enable the rack 61 and the gear 63 to move simultaneously to maintain a state of mutual engagement, the rack 61 is also slidably set on the telescopic part of the telescopic plate 2 62. In this way, when the side column 5 pushes the telescopic plate 2 62 through the mounting plate, the gear 63 and the rack 61 can move simultaneously. Moreover, since the rack 61 is also connected to the telescopic end 1 4 through the telescopic plate 1 6, when the telescopic end 1 4 moves, the rack 61 will also move with the telescopic end 1 4.

[0049] An auxiliary reinforcement mechanism is provided on the surface of the axis of gear 63. When the detachable column 12 approaches the concrete column and the support angle piece 11 on the upper telescopic end 13 contacts the concrete column, the auxiliary reinforcement mechanism strengthens the contact between the support angle piece 11 and the concrete column. By providing the auxiliary reinforcement mechanism, when the support angle piece 11 on the detachable column 12 contacts the external formwork of the concrete column, the auxiliary reinforcement mechanism can generate a pulling force on the detachable column 12 directed toward the main column 1, thereby strengthening the detachable column 12 after installation and preventing installation hazards.

[0050] The auxiliary reinforcement mechanism includes a screw rod 65 rotatably mounted on the telescopic plate 62 and connected to the gear 63 via a connecting portion, and a reinforcement plate 69 threadedly mounted on the screw rod 65. When the side column 5 approaches the concrete column and the support angle piece 11 on the telescopic end 51 contacts the concrete column, the outer periphery of the reinforcement plate 69 contacts the surface of the concrete column. When the telescopic end 4 moves upward, the rack 61 drives the gear 63 to rotate, thereby rotating the screw rod 65. At this time, the reinforcement plate 69, which is threaded with the screw rod 65, moves on the screw rod through the thread structure with the screw rod. Since the outer periphery of the reinforcement plate 69 contacts the surface of the concrete column, it is equivalent to forming a limit for the reinforcement plate 69, and the reinforcement plate 69 now moves in the direction close to the detachable column 12.

[0051] It should be noted here that since the side column 5 approaches the concrete column and the rotation of the screw rod 2 65 is carried out simultaneously, when the screw rod 2 65 starts to rotate, since the side column 5 may have a large gap with the formwork outside the concrete column, the reinforcing plate 69 may not be restricted and rotates together with the screw rod 2 65. However, as the side column 5 drives the screw rod 2 65 to approach the surface of the concrete column, the outer side of the reinforcing plate 69 will contact the surface of the formwork outside the concrete column with continued rotation. At this time, the reinforcing plate 69 is equivalent to being restricted and no longer rotates with the screw rod 2 65, but moves on the screw rod 2 65 toward the direction close to the detachable column 12. In order to achieve this effect, the vertical length of the reinforcing plate 69 in the initial state on the screw rod 2 65 can be set longer, so that after it rotates slightly with the screw rod 2 65, the upper and lower ends will respectively contact the surface of the formwork outside the concrete column, so that the reinforcing plate 69 can be moved after a shorter time.

[0052] The auxiliary reinforcement mechanism also includes an extension end 612 fixedly arranged on the surface of the detachable column 12. The side surface of the extension end 612 close to the reinforcement plate 69 is in the same plane as the side surface of the concrete column, and when the supporting angle piece 11 on the telescopic end three 13 is in contact with the surface of the concrete column, the gap between the extension end 612 and the concrete column is smaller than the width of the reinforcement plate 69. When the reinforcing plate 69 moves toward the direction close to the detachable column 12, the reinforcing plate 69 is limited by abutting against the surface of the outer template of the concrete column to move on the screw rod 2 65. In this way, when the reinforcing plate 69 moves to the end of the outer template of the concrete column, the gap between the extension end 612 and the concrete column is smaller than the width of the reinforcing plate 69, and the side surface of the extension end 612 close to the reinforcing plate 69 is in the same plane as the side surface of the concrete column. In this way, the extension end 612 will have the same effect as the outer template of the concrete column, so that the reinforcing plate 69 continues to move until the reinforcing plate 69 passes the extension end 612. At this time, the reinforcing plate 69 is no longer limited and moves with the screw rod. And rotate, so that the reinforcing plate 69 rotates to abut against the outer surface of the extension end 612. At this time, the detachable column is reinforced by the reinforcing plate 69. When the concrete column is poured, the detachable column 12 and the main column 1 are subjected to outward pressure, and the reinforcing plate 69 will be pulled to prevent the problem of mold explosion. By turning the knob 2 with the tool, not only can the supporting angle pieces 11 on the main column 1, the side column 5 and the detachable column 12 support the formwork outside the middle concrete column, but the reinforcing plate 69 can also be used to structurally reinforce the detachable column 12, thereby improving the overall strength during pouring. The entire process can be achieved by only turning the knob 2 with the tool, and the operation is convenient.

[0053] A retaining plate 611 is fixedly mounted on the extension end 612. When the reinforcing plate 69 moves to the end of the extension end 612 and rotates to mate with the retaining plate 611, the connecting portion separates the gear 63 from the screw, and the screw stops rotating. After the reinforcing plate 69 passes the extension end 612, the reinforcing plate 69 rotates with the second screw 65 without being restricted until the reinforcing plate 69 mates with the retaining plate 611. At this point, the reinforcing plate 69 can neither rotate nor continue to move with the rotation of the screw. At this point, the gear 63 is separated from the second screw 65 through the connecting portion. At this time, the power of the gear 63's rotation cannot be transmitted to the second screw 65, and the position of the reinforcing plate 69 is now fixed.

[0054] In one embodiment of the present invention, the connecting portion includes an end face tooth 1 66 and an end face tooth 2 67 that fit together, and the end face tooth 1 66 is connected to the gear 63 through a spring 1 68. After the reinforcing plate 69 is limited by the clamping plate 611, the reinforcing plate 69 can neither rotate nor continue to move with the rotation of the screw rod. At this time, the screw rod 2 65 cannot rotate, and the spring 1 68 will vibrate repeatedly, causing the end face tooth 1 66 and the end face tooth 2 67 to form a tooth-playing phenomenon. At this time, the power transmission is terminated and the position of the reinforcing plate 69 is fixed.

[0055] It should be noted that after the pouring is completed and the concrete solidifies, when the detachable column 12 needs to be disassembled, a limit block 613 is fixedly provided on the card plate 611, and a protrusion 610 is also provided on the reinforcing plate 69. Since the knob 2 is reversed at this time, the rack 61 moves downward with the telescopic end 4, and the gear 63 drives the screw 2 65 to rotate in the opposite direction. At this time, the reinforcing plate 69 is not restricted and also rotates in the opposite direction with the screw 2 65 until the protrusion 610 is stuck in the limit block 613. At this time, the limit block 613 forms a limit on the reinforcing plate 69, causing the reinforcing plate 69 to move toward the initial position, thereby releasing the reinforcing effect of the reinforcing plate 69 on the detachable column 12, so as to facilitate the subsequent disassembly of the detachable column 12.

[0056] The rapid support system also includes a limit mechanism, located between the removable column 12 and the pulling mechanism. When the support angle piece 11 on the telescopic end 3 13 contacts the concrete column surface, the limit mechanism stops the pulling mechanism from pulling the removable column 12. This prevents the removable column 12 from moving beyond its limit and causing overall deformation.

[0057] In one embodiment of the present invention, the limiting mechanism includes an inclined plate 8 set in the pulling arm 3 by a torsion spring rotation, and two extrusion blocks 83 connected by a spring, wherein one extrusion block 83 is against the surface of the inclined plate 8, and the other extrusion block 83 is set relative to the surface of the concrete column. When the detachable column 12 approaches the template surface outside the concrete column, the extrusion block 83 rotates the inclined plate 8 by squeezing the second spring 82, so that the inclined plate 8 pushes the resistance rod 81 slidingly set thereon, and the resistance rod 81 is rotated away from the end of the inclined plate 8 and is set on the surface of the polygonal column 35. In this way, the resistance rod 81 is pushed by the inclined plate 8, so that the resistance rod 81 pushes the polygonal column 35 to slide on the screw 32 until the polygonal column 35 is pushed. The column 35 is disengaged from the corresponding through hole opened on the vertical plate 34. At this time, the screw 32 rotates together with the basket bolt 31 and can no longer pull the sliding plate 37 to move. At this time, the position of the sliding plate 37 and the pulling arm 3 is fixed, so that the position of the side column 5 and the detachable column 12 is fixed. The main column 1, the side column 5 and the supporting angle piece 11 on the detachable column 12 can support the formwork outside the concrete column only by rotating. After the fixing is completed, the side column 5 and the detachable column 12 can be automatically limited to prevent deformation due to excessive movement. The use effect is better and no other operations are required. It can be completed by turning the knob 2. The operation is very convenient and suitable for promotion and use.

[0058] A vertical rod 9 is provided on the extension end 612 through a spring three 92. A pressure ring 93 and a wedge block 1 91 are provided on the top port and the bottom port of the vertical rod 9 respectively. When the screw rod 2 65 rotates in the opposite direction, the reinforcing plate 69 contacts the pressure ring 93 to move the vertical rod 9 downward. When it is necessary to dismantle the detachable column 12, the knob 2 is rotated in the opposite direction to rotate the screw rod 2 in the opposite direction. At this time, the reinforcing plate 69 rotates in the opposite direction and contacts the pressure ring 93, and the vertical rod 9 moves downward. After the vertical rod 9 moves downward, it squeezes the inclined plate 8 through the wedge block 1 91, causing the torsion spring and the spring 2 82 on the inclined plate 8 to deform. At this time, the inclined plate 8 pulls the polygonal column 35 to be re-inserted into the through hole on the vertical plate 34. At this time, the screw rod 32 is restricted again, and the screw rod 32 is pushed outward by the rotation of the basket bolt 31, thereby pushing the sliding plate 37, the pulling arm 3 and the detachable column 12 outward, so that the detachable column 12 is separated from the concrete column.

[0059] It should be noted that when the reinforcing plate 69 pushes the pressure ring 93 downward, that is, when the protrusion 610 on the reinforcing plate 69 abuts against the surface of the limit block 613, the reinforcing plate 69 moves towards the initial position under the drive of the screw rod 2 65, the reinforcing plate 69 disengages from the pressure ring 93, the spring 3 92 recovers its deformation, and the wedge block 1 91 disengages from the inclined plate 8. The purpose of this design is that only after the reinforcing plate 69 disengages from the clamping plate 611, the wedge block 1 91 is used to enable the inclined plate 8 to pull the polygonal column 35 back into the through hole on the vertical plate 34, so that the disengagement action of the reinforcing plate 69 and the extension end 612 is not synchronized with the action of the detachable column 12 away from the concrete column, so as to prevent the detachable column 12 from getting stuck in the reinforcing plate 69 when it is away from the concrete column, causing the reinforcing plate 69 to be unable to restore to its initial position and affecting the efficiency during the next use.

[0060] It should also be noted that there is an elastic arrangement between the pressure ring 93 and the vertical rod 9. When the detachable column 12 is reinforced by the reinforcing plate 69, the reinforcing plate 69 and the pressure ring 93 are offset against each other, so that the pressure ring 93 can be moved away from the vertical rod 9. When the reinforcing plate 69 is stuck in the block and disengaged from the pressure ring 93, the pressure ring 93 returns to its original position, thereby not causing movement limitation of the reinforcing plate 69.

[0061] The limiting mechanism is provided with a slant plate 8 via a torsion spring, and the contact point between the slant plate 8 and the pulling arm 3 via the torsion spring is located on the same side of the wedge block 91 and the extrusion block 83. This ensures that when the wedge block 91 contacts the slant plate 8, the slant plate 8 can be rotated, causing the contact rod 81 on it to pull the polygonal pillar 35 back into the through hole on the vertical plate 34.

[0062] It should be noted that in order to reduce the friction between the support angle piece 11 and the external formwork of the concrete column, a pulley can be provided on the surface of the side of the support angle piece 11 close to the formwork. In this way, even if the support angle piece 11 has not moved to the top of the formwork and has already been in contact with the formwork surface, the support angle piece 11 can still be raised.

[0063] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
