Description

Technical Field

[0001] The utility model relates to the technical field of steel cage construction, and more specifically, to a steel cage inner support structure that is conveniently disassembled and recyclable. Background Art

[0002] In the current construction industry, the construction quality of piers and pile foundations is directly related to the stability and safety of the overall structure. To effectively prevent the deformation of the steel cage during transportation and hoisting, the traditional method is to add reinforcing bars and steel bar inner support structures inside it. Generally, welding is used to connect the inner support and the reinforcing bars. This method not only has complex construction, consumes time and effort, but also the welding materials are difficult to be fully recycled and reused, resulting in waste of resources. More importantly, before the steel cage is lowered, the inner support needs to be removed by knocking. This process is extremely easy to damage the steel cage itself and even cause the main bars to become loose, thereby affecting the overall strength and stability of the steel cage and bringing inconvenience and safety hazards to the subsequent construction. Summary of the Utility Model

[0003] To make up for the above deficiencies, the utility model provides a steel cage inner support structure that is conveniently disassembled and recyclable to solve the above problems.

[0004] The utility model is implemented as follows:

Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0022] Accordingly, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0023] As Figures 1-3 shown, the present invention provides a convenient disassembly and recyclable internal support structure for a steel cage, which includes an installation box 10. The installation box 10 includes a box body 11 and a box cover 12. A plurality of through holes 1102 are circumferentially and equally spaced on the outer side of the box body 11. On one side of the top of the box cover 12, a braking box 1201 is provided. A linkage support assembly 20 is arranged inside the box body 11. The linkage support assembly 20 includes a main connection seat 21 arranged at the center of the bottom wall of the box body 11. The same number of main support rods 2101 as the through holes 1102 are circumferentially and equally spaced on the side surface of the main connection seat 21. An extension support member 22 is slidably arranged at the end of the main support rod 2101. The extension support member 22 extends outward from the box body 11 through the through hole 1102. A star gear 23 is arranged on the top of the main connection seat 21. The star gear 23 is slidably connected to the extension support member 22. A braking assembly 30 is arranged inside the braking box 1201. The braking assembly 30 passes through the box cover 12 and is connected to the star gear 23. It also includes a rotating handle 40. The rotating handle 40 is movably connected to the braking assembly 30. Among them, a lifting ring 13 is arranged at the center of the top of the box cover 12, and a lifting ring 13 is also arranged at the center of the bottom of the box body 11. During use, several of these internal support structures are used at intervals inside the steel cage for support. By engaging the rotating handle with the worm 34 at the braking assembly 30, the extension support member 22 is expanded or contracted by rotation. Each of these internal support structures is connected to the adjacent lifting rings 13 through a connecting rope 14. After fixing these internal support structures, when lowering the steel cage in cooperation with a crane, the rotating handle is used to loosen the internal support structures located on the ground in sequence, and finally all the internal support structures are recovered through the topmost internal support structure.

[0024] As Figures 2-3 shown, the main connection seat 21 includes a main shaft 2103 arranged at the center of its top. The star gear 23 is rotatably arranged on the main shaft 2103. A sliding groove 2102 is provided at the end of the main support rod 2101. On one side of the end of one of the main support rods 2101, a boss 2104 is provided. A protruding portion 1101 is arranged on the outer side of the installation box 10 near the main support rod 2101 with the boss 2104.

[0025] In this embodiment, the extension support member 22 includes a secondary support rod 2201. One end of the secondary support rod 2201 is provided with an arc-shaped support plate 2202. At the top of the secondary support rod 2201, away from the arc-shaped support plate 2202, a sliding anchor rod 2203 is provided. At the top end of the sliding anchor rod 2203, a limiting convex block 2204 is provided.

[0026] In this embodiment, several arc-shaped grooves 2301 are circumferentially and equally spaced along the axis at the top of the sun gear 23. The number of arc-shaped grooves 2301 is the same as the number of through holes 1102.

[0027] In this embodiment, one end of the secondary support rod 2201 close to the sliding anchor rod 2203 is slidably arranged in the sliding groove 2102. The sliding anchor rod 2203 sequentially penetrates through the sliding groove 2102 and one of the arc-shaped grooves 2301. The limiting convex block 2204 abuts against the top of the sun gear 23.

[0028] In this embodiment, a limiting flange is provided on the side wall of the sliding groove 2102, and a limiting groove meshing with the limiting flange is provided on the side wall of the secondary support rod 2201. The cooperation of the two improves the sliding stability of the secondary support rod 2201.

[0029] In this embodiment, the braking assembly 30 includes a first transmission gear 31, a second transmission gear 32, a transmission shaft 33 and a worm 34. The first transmission gear 31 is arranged on one side close to the top of the transmission shaft 33. The second transmission gear 32 is arranged on one side close to the bottom of the transmission shaft 33. And the transmission shaft 33 is rotatably arranged between the boss 2104 and the top wall of the brake box 1201. The second transmission gear 32 meshes with the sun gear 23. A worm 34 is arranged inside the brake box 1201. One end of the worm 34 extends to the outside of the brake box 1201. The worm 34 meshes with the first transmission gear 31.

[0030] Specifically, the working principle of the convenient disassembly and recyclable internal support structure of the steel reinforcement cage is as follows: during use, several such internal support structures are placed at intervals inside the steel reinforcement cage, and during installation, it is ensured that the internal support structure is coaxial with the steel reinforcement cage. The rotating handle is docked with the worm 34, thereby driving the first gear, the second gear and the star gear 23 in sequence. At this time, the arc-shaped groove 2301 on the star gear 23 exerts an oblique moving force on the sliding bolt 2203 on the extended support member 22, and the sliding groove 2102 restricts the moving direction of the secondary support rod 2201, so as to realize the telescopic movement of the extended support member 22, and then form a contact with the inner side wall of the steel reinforcement cage. During recycling, the extended support member 22 can be recycled by rotating the handle 40 again. Through the above structure, the problems of the existing internal support structure, such as complex construction, time-consuming and laborious, difficult to completely recycle and reuse the welding materials, wasting resources, and causing damage to the steel reinforcement cage itself when knocking to remove the internal support before the steel reinforcement cage is lowered, thereby causing the main bars to loosen and affecting the overall strength and stability of the steel reinforcement cage, bringing inconvenience and potential safety hazards to the subsequent construction, are solved.

[0031] The above further describes the present invention with the aid of specific embodiments. However, it should be understood that the specific description here should not be construed as a limitation on the essence and scope of the present invention. Various modifications made by those of ordinary skill in the art to the above embodiments after reading this specification all fall within the scope protected by the present invention.
