[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figures 1-6 As shown, the utility model provides a technical solution:

[0027] A reusable steel cage placement system includes a hanging bar assembly, which is used to connect the reinforcement ring on the steel cage and lower the steel cage into a hole. The hanging bar assembly includes a hook 1 and a connecting bar 2. The hook 1 is set at one end of the connecting bar 2, and a lifting ring 3 is set at the other end of the connecting bar 2. The hook 1 includes a left hook 11 and a right hook 12. The opening directions of the left hook 11 and the right hook 12 are set in opposite directions, and the left hook 11 and the right hook 12 are not located in the same plane; a support platform is set on the outside of the hole, which is used to support the hanging bar assembly for lifting the steel cage, including a support frame 4 and a carrying bar 5. The carrying bar 5 is movably set on the support frame 4, and the carrying bar 5 is used to connect with the lifting ring 3.

[0028] In this embodiment, a gap 6 is set between the left hook 11 and the right hook 12, and the size of the gap 6 is larger than the cross-sectional diameter of the reinforcement ring on the steel cage. At the same time, the inner hook area of ​​the left hook 11 and the right hook 12 is larger than the radial cross-sectional area of ​​the reinforcement ring, so that the reinforcement ring can enter the gap 6 conveniently and the left hook 11 and the right hook 12 can cooperate to hook the reinforcement ring by rotating the hook 1. The connection and separation of the hook 1 and the reinforcement ring can be achieved by rotating the hook 1, thereby avoiding the problem of excessive resistance when moving the hook 1 horizontally in concrete, thereby improving the construction efficiency.

[0029] In this embodiment, the connecting rib 2 includes several ribs, and the ribs can be threaded steel bars. One rib is connected to the hook 1 as rib 1 7, and the other rib is connected to the ring 3 as rib 2 8. The ribs are connected by a fixing component 9, which is used to adjust and fix the overall length of the connecting rib 2. The number of ribs and the overall length of the connection between the ribs can be determined according to the height of the lowering of the steel cage. Then, the overall length of the connecting rib 2 is fixed by the fixing component 9, which can adapt to different construction requirements and improve the practicality of the device.

[0030] In this embodiment, the fixing assembly 9 includes a U-shaped card 91, a movable plate 92 and a nut 93. Threads are set at both ends of the U-shaped card 91. The U-shaped card 91 is sleeved at the position where two adjacent ribs overlap. The movable plate 92 is inserted into the opening of the U-shaped card 91. The nuts 93 are set at both ends of the U-shaped card 91 and are threadedly connected to limit the position of the movable plate 92. The side of the movable plate 92 close to the rib can be set to an arc shape that fits the outer surface of the rib to improve the stability of the connection.

[0031] In this embodiment, at least three sets of fixing components 9 are set at the connection position of each two adjacent ribs, and the openings of the U-shaped clips 91 of the fixing components 9 are oriented in the same direction, and can be symmetrically tightened with a handheld power tool, thereby improving the stability of the rib connection and the safety of construction.

[0032] In this embodiment, the support frame 4 is configured as an assembled frame structure, including side frame 1 41, side frame 2 42, side frame 3 43 and side frame 44 of the same size. Side frame 1 41, side frame 2 42, side frame 3 43 and side frame 44 are clamped together to form a square frame and are arranged on the outer edge of the hole. Specifically, the two ends of side frame 1 41 are inclined at 45 degrees relative to each other, a triangular connecting block is provided at one end, and a connecting groove is provided at the other end corresponding to the connecting block. The connecting block can be inserted into the connecting groove, and corresponding connecting holes are provided on the connecting block and the connecting groove for setting connecting bolts. Side frame 1 41, side frame 2 42, side frame 3 43 and side frame 44 are plugged in and connected end to end and fixed by connecting bolts, which is convenient for disassembly and movement while improving stability. A sliding seat 45 is provided above side frame 1 41, side frame 2 42, side frame 3 43 and side frame 44, and a sliding hole 46 is provided on the sliding seat 45, and the axial direction of the sliding hole 46 is consistent with the radial direction of the hole.

[0033] In another embodiment, the support frame 4 can also be set to other shapes, such as a circle, etc. In this case, the side frame 1 41, the side frame 2 42, the side frame 3 43 and the side frame 4 44 are 90° arcs, and the ends are connected as a whole to achieve the same supporting effect.

[0034] In this embodiment, the carrying bar 5 is slidably set in the sliding hole 46, and the end of the carrying bar 5 close to the hole is used to be inserted into the lifting ring 3 to support the lifting ring 3. A block can be set at the end of the carrying bar 5 away from the lifting ring 3 to prevent the carrying bar 5 from sliding out of the sliding hole 46, which reduces the labor intensity of construction workers and improves the safety of the use of the device.

[0035] Working principle: First, a circle of reinforcement ring is set on the top of the steel cage; the overall length of the connecting rib 2 is adjusted according to the placement elevation of the steel cage. Specifically, two or more ribs are connected to each other through the fixing assembly 9, and the U-shaped clip 91 is set at the position where two adjacent ribs overlap. Then the movable plate 92 is inserted from the opening of the U-shaped clip 91 so that the rib is located in the space surrounded by the U-shaped clip 91 and the movable plate 92. Then the nut 93 is installed on the U-shaped clip 91, which can be symmetrically tightened with a handheld electric tool to press the movable plate 92 to limit the movement of the movable plate 92, and at the same time, the adjacent two ribs are connected by the extrusion between the U-shaped clip 91 and the movable plate 92 and the friction between the ribs. Preferably, no less than three sets of fixing assemblies 9 are set at the connection between each two adjacent ribs, and the openings of the U-shaped clips 91 of the fixing assemblies 9 are in the same direction; the support platform is installed and set outside the hole; then the hook 1 is connected to the reinforcement ring, specifically, the length direction of the interval 6 between the left hook 11 and the right hook 12 is consistent with the reinforcement ring. The length direction of the strong ring is set parallel, and the hook 1 is moved so that the reinforcement ring is inserted from the gap 6 between the left hook 11 and the right hook 12. After reaching the top of the hook 1, the hook 1 is rotated. Since the opening directions of the left hook 11 and the right hook 12 are in opposite directions, and the inner spaces of the hooks of the left hook 11 and the right hook 12 are slightly larger than the cross-sectional area of ​​the reinforcement ring cross section, the hook 1 can hook the reinforcement ring and lower the steel cage into the hole through the sling assembly; after the steel cage is put into place, the carrying bar 5 is inserted into the lifting ring 3 to support the entirety of the steel cage and the sling assembly, so as to avoid the position change of the steel cage and reduce the labor intensity of the construction workers; then concrete is poured into the hole; after the concrete pouring is completed, the carrying bar 5 is slid backward to exit the lifting ring 3, and the sling assembly is manually pressed downward for a distance to disengage the hook 1 from the reinforcement ring, and then the sling assembly is rotated so that the gap 6 direction of the hook 1 is parallel to the length direction of the reinforcement ring again, so that the reinforcement ring can be removed from the gap 6, and then the sling assembly is pulled out upward and cleaned for reuse next time.
