[0028] In this embodiment, a first cross bar insertion key 10 is provided between the first support claw 3 and the second support claw 4; a second cross bar insertion key 11 is provided between the second support claw 4 and the fourth support claw 6; a third cross bar insertion key 12 is provided between the fourth support claw 6 and the third support claw 5; a fourth cross bar insertion key 13 is provided between the third support claw 5 and the first support claw 3; the first cross bar insertion key 10, the second cross bar insertion key 11, the third cross bar insertion key 12, and the fourth cross bar insertion key 13 are all connected to the side of the screw joint 2.
[0029] Specifically, through the existing steel pipe plug-in joint, the horizontal steel pipe installation can be carried out in conjunction with the cross bar insertion key, wherein the steel pipe can be inserted in front of the top support guide sleeve 1 between the first support claw 3 and the second support claw 4 through the first cross bar insertion key 10, the steel pipe can be inserted on the left side of the top support guide sleeve 1 between the second support claw 4 and the fourth support claw 6 through the second cross bar insertion key 11, the steel pipe can be inserted behind the top support guide sleeve 1 between the fourth support claw 6 and the third support claw 5 through the third cross bar insertion key 12, and the steel pipe can be inserted on the right side of the top support guide sleeve 1 between the third support claw 5 and the first support claw 3 through the fourth cross bar insertion key 13.
[0030] In this embodiment, the early disassembly assembly also includes an early disassembly sleeve 14 and an early disassembly snap ring 15; the early disassembly screw 9 also passes through the center of the early disassembly sleeve 14; the lower end of the jacking guide sleeve 1 is located inside the early disassembly sleeve 14, and the early disassembly snap ring 15 is fixed at the interface position of the early disassembly sleeve 14 and the jacking guide sleeve 1; a snap-fitting notch 16 is formed at the bottom of the jacking guide sleeve 1; the early disassembly snap ring 15 is formed with a first snap-fitting port 17 and a second snap-fitting port 18 that are interconnected; a snap-fitting step 19 is formed on the inner wall of the first snap-fitting port 17, and the snap-fitting step 19 is inserted into the snap-fitting notch 16 to lock the jacking guide sleeve 1; the snap-fitting step 19 on the inner wall of the first snap-fitting port 17 is disengaged from the snap-fitting notch 16 by knocking on the side of the early disassembly snap ring 15; after the snap-fitting step 19 is disengaged from the snap-fitting notch 16, the locking of the jacking guide sleeve 1 is released, and the early disassembly snap ring 15 is allowed to move up and down along the outside of the early disassembly sleeve 14 through the second snap-fitting port 18.
[0031] Among them, the top of the early-removal screw rod 9 is screwed with an adjustable movable support plate 20; a supporting wooden square 21 is arranged above the support tube, and a supporting template 22 is provided at the upper end of the supporting wooden square 21; the adjustable movable support plate 20 is in the gap of the supporting wooden square 21 and supports the supporting template 22.
[0032] Specifically, the inner diameters of the first bayonet 17 and the second bayonet 18 are different. The inner diameter of the first bayonet 17 is smaller than the inner diameter of the second bayonet 18 and the outer diameter of the early-removal sleeve 14. Since a snap-fit step 19 is formed on the inner wall of the first bayonet 17 and a snap-fit notch 16 is formed on the bottom of the jacking guide sleeve 1, the snap-fit step 19 can be embedded in the snap-fit notch 16, thereby locking the interface position of the jacking guide sleeve 1 and the early-removal sleeve 14.

[0033] See also Figure 4 Since the inner diameter of the second bayonet 18 is larger than the outer diameter of the early-removal sleeve 14, the early-removal clamp 15 can slide down along the outer wall of the early-removal sleeve 14. Then, the locking of the jacking guide sleeve 1 is released, and the support pipe and support wood 21 on the jacking guide sleeve 1 are removed. As needed, part of the support formwork 22 can be removed, leaving only the edge of the support formwork 22. Under the premise of ensuring stable support for the formed concrete component, as much of the support system of steel, wood and formwork as possible can be quickly and conveniently removed to improve the turnover efficiency of the support pipe, support wood 21 and support formwork 22.
[0034] In one possible embodiment, a first adjustment nut is connected to the interface between the early-removal screw rod 9 and the column, with first nut adjustment arms provided on both sides of the first adjustment nut.

[0037] Second, pour concrete. After the concrete reaches a certain strength, the support formwork 22 is dismantled early. First, the support wood 21 is removed, then the support pipe, and then part of the support formwork 22 is removed, and part of the support formwork 22 is retained.
[0038] Third, remove some of the movable fasteners and some of the reinforcing crossbars of the support system, and then remove the remaining frame and support formwork 22 after the concrete is completely solidified.
[0039] To sum up, the utility model is provided with a top support guide sleeve 1, a screw rod joint 2, a first support claw 3, a second support claw 4, a third support claw 5 and a fourth support claw 6; an introduction hole 7 is formed in the center of the top support guide sleeve 1, and the screw rod joint 2 is formed on the upper part of the top support guide sleeve 1, and a screw rod connection hole 8 is formed in the center of the screw rod joint 2, and the introduction hole 7 and the screw rod connection hole 8 are connected to each other. The screw rod joint 2 is provided with an early disassembly component, and the early disassembly component includes an early disassembly screw rod 9, and the early disassembly screw rod 9 passes through the screw rod connection hole 8 and the introduction hole 7 that are connected to each other; the first support claw 3 and the second support claw 4 are symmetrically connected on both sides of the front of the screw rod joint 2, and the third support claw 5 and the fourth support claw 6 are symmetrically connected on both sides of the rear of the screw rod joint 2; a support tube is placed on the upper part of the first support claw 3 and the third support claw 5; another support tube is placed on the upper part of the second support claw 4 and the fourth support claw 6. Through the existing steel pipe plug-in joint, the horizontal steel pipe installation can be carried out in conjunction with the cross bar insertion key, wherein the steel pipe can be inserted in front of the top support guide sleeve 1 between the first support claw 3 and the second support claw 4 through the first cross bar insertion key 10, the steel pipe can be inserted on the left side of the top support guide sleeve 1 between the second support claw 4 and the fourth support claw 6 through the second cross bar insertion key 11, the steel pipe can be inserted at the rear of the top support guide sleeve 1 between the fourth support claw 6 and the third support claw 5 through the third cross bar insertion key 12, and the steel pipe can be inserted on the right side of the top support guide sleeve 1 between the third support claw 5 and the first support claw 3 through the fourth cross bar insertion key 13. The inner diameters of the first bayonet 17 and the second bayonet 18 are different. The inner diameter of the first bayonet 17 is smaller than the inner diameter of the second bayonet 18 and the outer diameter of the early-removal sleeve 14. Since the inner wall of the first bayonet 17 is formed with a snap-fitting step 19 and the bottom of the jacking guide sleeve 1 is formed with a snap-fitting notch 16, the snap-fitting step 19 can be embedded in the snap-fitting notch 16, thereby locking the interface position between the jacking guide sleeve 1 and the early-removal sleeve 14. When it is necessary to early-remove the support tube, support wood 21, and support template 22 on the first support claw 3, the second support claw 4, the third support claw 5, and the fourth support claw 6, the early-removal snap ring 15 is knocked from the side to release the snap-fitting step 19 on the inner wall of the first bayonet 17 from the snap-fitting notch 16 and release the locking state. Since the inner diameter of the second bayonet 18 is larger than the outer diameter of the early-removal sleeve 14, the early-removal snap ring 15 can slide down along the outer wall of the early-removal sleeve 14. The locking mechanism of the jacking guide sleeve 1 is then released, and the support tube and support wood 21 on the jacking guide sleeve 1 are removed. As needed, the support formwork 22 can be partially removed, retaining only the edge portions of the support formwork 22. While ensuring stable support for the formed concrete component, the support system of as much steel, wood, and formwork as possible can be quickly and conveniently removed, improving the turnover efficiency of the support tube, support wood 21, and support formwork 22. This utility model allows for quick and convenient removal of as much steel, wood, and formwork as possible while ensuring stable support for the formed concrete component, resulting in greater ease of use and improved support effectiveness.
