DETAILED DESCRIPTION

[0038] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0039] like Figure 1-7As shown, a steel cage positioning device comprises a positioning ear 1 and a clamping assembly, wherein the clamping assembly is fixedly mounted at both ends of the positioning ear 1;

[0040] The clamping assembly is fixedly connected to the longitudinal reinforcement on the steel cage; the positioning ears can control the position of the steel cage in the concrete structure to ensure the concrete thickness of the steel cage protective layer;

[0041] Furthermore, the material of the positioning ears and the clamping components can be selected from recycled plastic or metal, preferably recycled plastic. By remelting the recycled plastic and forming it into an integral part using a mold, mass production can be achieved, reducing production costs and use costs during construction, and facilitating promotion during pile foundation construction. At the same time, the positioning bars and clamping components made of plastic are light in weight, which is convenient for workers to install on-site according to the predetermined installation positions in the drawings during the hoisting of the steel cage, effectively preventing the steel cage from being damaged during storage, transportation and hoisting after the positioning bars are pre-welded, reducing the process of replacing and re-welding the positioning bars on the longitudinal bars of the steel cage, and helping to shorten the construction period.

[0042] Furthermore, in order to prevent the positioning ears from falling off during the lifting process, several sets of low-cost positioning ears and clamping components can be arranged on the longitudinal reinforcement of the steel cage;

[0043] The clamping components and the longitudinal reinforcement on the steel cage are fixed by snap connection and rotation, which enables workers to quickly get started without special training and certification. There is no need to specially arrange professional construction personnel to weld positioning reinforcement to ensure the protective layer of the steel cage, and it can be installed anytime and anywhere, effectively reducing the use of manpower, materials and machines and cutting construction costs.

[0044] Specifically, the positioning ear 1 is cylindrical, and the two ends of the positioning ear 1 are bent relative to each other in a C-shape. The arc-shaped corners of the C-shape can reduce the scratching between the positioning ear and the pile foundation mud wall during the lifting process, thereby ensuring the stability and smoothness of the positioning ear during lifting in the pile foundation.

[0045] Specifically, the clamping assembly includes a movable part 2 and a fixed part 3, and the movable part 2 is movably mounted on the outer peripheral surface of the fixed part 3;

[0046] The two end surfaces of the positioning ear 1 are fixedly connected to the outer peripheral surface of the fixing member 3 respectively.

[0047] Specifically, the movable member 2 includes a sleeve 201, a longitudinal opening 203 is formed on the side wall of the sleeve 201 along the axial direction, and a transverse opening 204 is formed in the middle of the side wall of the sleeve 201 along the radial direction; one end of the transverse opening 204 is connected to the middle of the longitudinal opening 203;

[0048] The sleeve 201 is provided with a threaded through hole 202 , and the threaded through hole 202 corresponds to the position of the closed end of the transverse opening 204 .

[0049] Specifically, the height of the transverse opening 204 corresponds to the outer dimension of the positioning ear 1 , so that the sleeve can slide along the positioning ear when passing through the positioning ear, thereby ensuring the rotation of the sleeve.

[0050] Specifically, the fixing member 3 includes a limiting plate 301 and a positioning clip 302. One end of the positioning clip 302 is integrally formed with the limiting plate 301. The limiting plate can limit the sleeve 201 to prevent the sleeve from being separated from the positioning clip, thereby ensuring the connection stability between the sleeve and the positioning clip.

[0051] The limiting plate 301 and the positioning clamp 302 are both provided with a clamping groove 304 along the axial direction;

[0052] A slide groove 303 is provided in the middle of the limit plate 301 in the radial direction, and the position of the slide groove 303 corresponds to the end position of the positioning ear 1. A thread groove is provided on the inner wall of the clamping groove 304, and the thread groove can engage with the external thread on the longitudinal reinforcement of the steel cage, thereby enhancing the stability of the connection between the clamping groove and the longitudinal reinforcement of the steel cage.

[0053] Specifically, it also includes an abutment component, which includes a handle 4 and a bolt 5. The handle 4 is fixedly connected to one end of the bolt 5, and the other end of the bolt 5 is movably connected to the abutment block 6. The bolt 5 is threadedly connected to the threaded through hole 202, and the abutment block 6 is slidably installed in the slide groove 303, so that the abutment block can be accommodated in the positioning clamp, and the bolt 5 can be rotated in the bolt through hole 202 by turning the handle to change the relative distance between the handle and the outer wall of the sleeve. Further, the bolt 5 drives the abutment block 6 to move the distance inside the sleeve and the positioning clamp, thereby realizing the abutment and fixing operation between the abutment block and the longitudinal reinforcement of the steel cage, and the fixed connection between the sleeve and the positioning clamp is realized by tightening the abutment block against the longitudinal reinforcement on the steel cage.

[0054] A method for using a reinforcement cage positioning device comprises the following steps:

[0055] S1. Keep the opening in the same direction, rotate the sleeve along the side wall of the positioning clamp, so that the longitudinal opening of the sleeve is consistent with the opening of the clamping groove on the positioning clamp;

[0056] S2. Clamp the steel bars and clamp the positioning frame onto the longitudinal bars of the steel cage according to the dimensions in the drawing;

[0057] S3, rotating the sleeve, rotating the sleeve along the side wall of the positioning frame, so that the side wall of the sleeve closes the positioning groove on the positioning clip;

[0058] S4, limit, turn the handle to make the bolt drive the abutment block to move into the clamping groove, and make the abutment block and the side wall of the clamping groove abut against the external thread on the longitudinal reinforcement to achieve limit.
