Description

Technical Field

[0001] This utility model relates to the field of steel reinforcement engineering technology, specifically a positioning system for transfer layer steel reinforcement. Background Technology

[0002] On-site installation of vertical precast components is a key and challenging aspect of the project. The quality of installation is crucial to structural safety. To achieve accurate connection of precast components, full-sleeve grouting connection technology is often used. During this process, ensuring the precise position of the precast reinforcing bars in each floor's cast-in-place composite layer, especially the transfer layer, is of paramount importance, as it directly affects whether the precast components can be successfully inserted, the smooth progress of subsequent work, and the overall quality of the structure.

[0003] To ensure accurate positioning, for example, Chinese utility model patent CN217840927U discloses a prefabricated transfer layer reinforcement positioning structure, including a cast-in-place column, a supporting template, a first limiting member, and several second limiting members spaced apart from bottom to top. Each second limiting member is located above the first limiting member, and each transfer layer reinforcement passes through each second limiting member from top to bottom and abuts against the first limiting member. The supporting template covers the vertical outer periphery of the first limiting member and several second limiting members, and the outer periphery of the first limiting member and several second limiting members is fixedly connected to the supporting template. The first limiting member and several second limiting members are all located inside the concrete of the cast-in-place column, and the supporting template is located on the outer periphery of the concrete of the cast-in-place column. Each transfer layer reinforcement is inserted into the concrete of the cast-in-place column and its upper end protrudes from the upper surface of the concrete of the cast-in-place column. The first limiting member restricts the movement of each transfer layer reinforcement in the vertical direction, and each second limiting member restricts the movement of each transfer layer reinforcement in the horizontal direction, so as to avoid the sleeve of the upper column being inconvenient to install due to the displacement of the transfer layer reinforcement.

[0004] To prevent collisions between pre-reserved reinforcing bars and horizontal reinforcing bars, as well as problems such as loosening, displacement, and settlement of reinforcing bars that may occur during concrete pouring and vibration, thereby affecting the structural performance and leaving potential quality hazards, a transfer layer reinforcing bar positioning system is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a rebar positioning system for transition layers, which has the advantage of precise rebar positioning and solves the problem of rebar loosening that may occur during concrete pouring and vibration.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rebar positioning system for a transition layer, comprising a fixed sleeve, two sliding blocks slidably connected to the outer surface of the fixed sleeve, a steel pipe fixed to the left side of the sliding blocks, and a plurality of positioning components slidably connected to the outer surface of the steel pipe, the positioning components being used to position the rebar;

[0007] An adjustment assembly is fixed to the left side of the steel pipe. The adjustment assembly is used to adjust the position of the steel pipe. Positioning rods are provided inside the two adjustment assemblies.

[0008] The positioning component includes a moving component, a positioning plate, a stabilizing block, and a positioning cylinder. The outer surface of the steel pipe is slidably connected to the moving component, the interior of the moving component is slidably connected to the stabilizing block, the top of the stabilizing block is fixed to the positioning plate, and the bottom of the stabilizing block is fixed to the positioning cylinder.

[0009] By adopting this technical solution, the positioning component can effectively prevent the rebar from shifting during positioning, thus ensuring overall stability. Furthermore, the positioning cylinder inside the positioning component can be replaced, allowing for the positioning of rebars of different sizes.

[0010] Furthermore, the moving component includes a positioning block, a rotating rod, and a pushing plate. The outer surface of the steel pipe is slidably connected to the positioning block, the interior of the positioning block is threadedly connected to the rotating rod, the bottom of the rotating rod is rotatably connected to the pushing plate, and the interior of the positioning block is slidably connected to the stabilizing block.

[0011] By adopting this technical solution, the rotating rod can be moved due to the extrusion of the thread by rotating the rotating rod, thereby making the push plate contact the steel pipe and increasing the friction between the push plate and the steel pipe, thus positioning the position of the positioning block.

[0012] Furthermore, the rotating rod is an externally threaded rod, and the positioning block has a threaded hole inside that matches the rotating rod.

[0013] Furthermore, friction pads are fixed on the opposite side of the positioning plate and the pushing plate, and a positioning groove adapted to the stabilizing block is opened on the right side of the positioning block.

[0014] By adopting this technical solution, the friction pad can be set to further improve the friction between the positioning plate, the pushing plate, and the steel pipe, thereby effectively ensuring the overall stability. The positioning groove can be set to allow the positioning plate, the stabilizing block, and the positioning cylinder to move to the right, so that different positioning cylinders can be replaced according to the size of the reinforcing bar.

[0015] Furthermore, a control block is fixed to the top of the rotating rod, and a friction strip is fixed to the outer surface of the control block.

[0016] By adopting this technical solution and using the control block, it becomes more convenient to rotate the rotating rod.

[0017] Furthermore, the adjustment assembly includes an adjustment block, a rotating block, and a stabilizing plate. The outer surface of the positioning rod is slidably connected to the adjustment block, the top of the adjustment block is rotatably connected to the rotating block threadedly connected to the positioning rod, and the stabilizing plate inside the adjustment block is fixedly connected to the positioning rod.

[0018] By adopting this technical solution, the stability of the adjusting block during movement can be effectively improved by setting a stabilizing plate, and the rotation of the adjusting block can be restricted. When the rotating block rotates, it will move due to the compression of the threads.

[0019] Furthermore, the bottom of the rotating block is fixed to the rotating plate that is slidably connected to the adjusting block, and the bottom of the rotating plate is fixed to the extension plate that is slidably connected to the adjusting block.

[0020] By adopting this technical solution, the rotating plate and the extension plate are designed to ensure that the rotating block does not affect the adjusting block when it rotates, and that the adjusting block does not separate from the rotating block.

[0021] Furthermore, both the steel pipe and the fixing sleeve are square tubes, and the push plate is fitted to the inner wall of the positioning block.

[0022] By adopting this technical solution, the steel pipe and the fixed sleeve are made into square tubes, so that neither the positioning block nor the sliding block can rotate, thus ensuring the overall stability. The push plate is attached to the inner wall of the positioning block, so that the push plate cannot rotate inside the positioning block either.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] 1. This transfer layer rebar positioning system, through its positioning components, effectively prevents rebar displacement during positioning, thereby ensuring overall stability. Furthermore, the positioning components are movable, allowing for convenient adjustment of their position according to site requirements. The overall structure is simple, effectively ensuring accurate rebar positioning, which facilitates subsequent processing and reduces the processing cycle.

[0025] 2. This conversion layer rebar positioning system allows for the replacement of the positioning cylinder inside the positioning component, enabling the positioning of rebars of different sizes. The adjustable component allows for the adjustment of the spacing and quantity between steel pipes, and the threaded adjustment effectively improves the accuracy of the adjustment. The overall structure is simple, making it more practical. Attached Figure Description

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1 to 3 In this embodiment, a rebar positioning system for a transition layer includes a fixed sleeve 1. Two sliding blocks 2 are slidably connected to the outer surface of the fixed sleeve 1. A steel pipe 3 is fixed to the left side of the sliding block 2. Multiple positioning components 4 are slidably connected to the outer surface of the steel pipe 3. The positioning components 4 are used to position the rebar.

[0032] In addition, an adjustment assembly 5 is fixed on the left side of the steel pipe 3. The adjustment assembly 5 includes an adjustment block 501, a rotating block 502, and a stabilizing plate 503. The outer surface of the positioning rod 6 is slidably connected to the adjustment block 501. The top of the adjustment block 501 is rotatably connected to the rotating block 502, which is threadedly connected to the positioning rod 6. The bottom of the rotating block 502 is fixed to the rotating plate 504, which is slidably connected to the adjustment block 501. The bottom of the rotating plate 504 is fixed to the extension plate, which is slidably connected to the adjustment block 501. By setting the rotating plate 504 and the extension plate, the rotation of the rotating block 502 will not affect the adjustment block 501, and the adjustment block 501 will not separate from the rotating block 502.

[0033] Furthermore, the internal stabilizing plate 503 of the adjusting block 501 is fixed to the positioning rod 6. The stabilizing plate 503 effectively improves the stability of the adjusting block 501 during movement and restricts the rotation of the adjusting block 501. When the rotating block 502 rotates, it will move due to the compression of the threads. The adjusting component 5 is used to adjust the position of the steel pipe 3. The positioning rod 6 is provided inside the two adjusting components 5.

[0034] In summary, by rotating the rotating block 502, the rotating block 502 can be moved due to the extrusion of the thread, thereby adjusting the position of the adjusting block 501 and the steel pipe 3, thus effectively improving the overall practicality.

[0035] Please refer to it again. Figure 3 In this embodiment, the positioning component 4 includes a moving component, a positioning plate 404, a stabilizing block 405, and a positioning cylinder 406. The outer surface of the steel pipe 3 is slidably connected to the moving component. The moving component includes a positioning block 401, a rotating rod 402, and a pushing plate 403. The outer surface of the steel pipe 3 is slidably connected to the positioning block 401. Both the steel pipe 3 and the fixed sleeve 1 are square tubes. By setting the steel pipe 3 and the fixed sleeve 1 as square tubes, the positioning block 401 and the sliding block 2 cannot rotate, thereby ensuring the overall stability.

[0036] In addition, the interior of the positioning block 401 is threadedly connected to the rotating rod 402. A control block 407 is fixed to the top of the rotating rod 402, and a friction strip is fixed to the outer surface of the control block 407. The control block 407 makes it easier to rotate the rotating rod 402. The rotating rod 402 is an externally threaded rod. The interior of the positioning block 401 has a threaded hole that matches the rotating rod 402. The bottom of the rotating rod 402 is rotatably connected to the push plate 403. The push plate 403 fits against the inner wall of the positioning block 401, thus preventing the push plate 403 from rotating inside the positioning block 401. The interior of the positioning block 401 is slidably connected to the stabilizing block 405. By rotating the rotating rod 402, the rotating rod 402 can move due to the compression of the threads, thereby causing the push plate 403 to contact the steel pipe 3 and increasing the friction between the push plate 403 and the steel pipe 3, thus positioning the position of the positioning block 401.

[0037] It should be noted that the interior of the moving component is slidably connected to the stabilizing block 405. The top of the stabilizing block 405 is fixed to the positioning plate 404. Friction pads are fixed on the opposite side of the positioning plate 404 and the pushing plate 403. A positioning groove adapted to the stabilizing block 405 is provided on the right side of the positioning block 401. The friction pads can further improve the friction between the positioning plate 404, the pushing plate 403, and the steel pipe 3, thereby effectively ensuring the overall stability. The positioning groove allows the positioning plate 404, the stabilizing block 405, and the positioning cylinder 406 to move to the right, so that different positioning cylinders 406 can be replaced according to the size of the reinforcing bar. The bottom of the stabilizing block 405 is fixed to the positioning cylinder 406.

[0038] In summary, the positioning cylinder 406 can be disassembled by pulling it to the right. When the push plate 403 contacts the steel pipe 3 for positioning, the friction between the positioning plate 404 and the steel pipe 3 will be increased, thus preventing the positioning cylinder 406 from moving to the right and ensuring overall stability.

[0039] The working principle of the above embodiments is as follows:

[0040] (1) Place the fixed sleeve 1, steel pipe 3 and positioning rod 6 on a flat ground. After sliding the sliding block 2 on the steel pipe 3 to the fixed sleeve 1, slide the adjusting block 501 to the positioning rod 6 and make the rotating block 502 contact the positioning rod 6. At this time, the rotating block 502 can be rotated to make the rotating block 502 threadedly connected to the positioning rod 6. The rotating block 502 can be continuously pushed to rotate as needed, so that the rotating block 502 moves due to the extrusion of the thread, which drives the adjusting block 501 and the steel pipe 3 to move.

[0041] (2) According to the measurement and layout positioning, place the fixing sleeve 1 and the positioning rod 6 at the position of the precast wall panel, and adjust the plane position to ensure that it is in a horizontal state. Use the steel bar head to weld and fix the fixing sleeve 1 to the positioning rod 6 and the main reinforcement of the precast wall panel structure. The fixed sleeve 1 and the positioning rod 6 after installation should be more than 5cm higher than the concrete pouring surface.

[0042] (3) Mark the position of the steel bars on the steel pipe 3 with a graphite pen according to the size relationship of the reserved steel bars in the design. Slide each positioning block 401 to the marked position. By rotating the rotating rod 402, the rotating rod 402 can be moved due to the extrusion of the thread, so that the pushing plate 403 contacts the steel pipe 3, thereby increasing the friction between the pushing plate 403, the positioning plate 404 and the steel pipe 3, thereby restricting the movement of the positioning block 401. Furthermore, due to the increased friction between the positioning plate 404 and the steel pipe 3, the stabilizing block 405 cannot move left or right, thus ensuring the stability of the stabilizing block 405 and the positioning cylinder 406. The overall structure is simple, so that when the steel bars are installed later, after the steel bars pass through the positioning cylinder 406, the steel bars are not easy to deviate, effectively ensuring the accurate position of the steel bars.
