Description

Technical Field

[0001] This utility model belongs to the field of auxiliary tools for rebar installation, and specifically relates to a new type of rebar installation positioning device. Background Technology

[0002] Rebar anchoring involves drilling holes, cleaning them, injecting high-strength anchoring adhesive into the holes, and then rotating the rebar to insert it into the center of the hole. After insertion, the rebar needs to be allowed to cure. During this curing process, the rebar's weight can cause it to sink to the bottom of the adhesive, and workers often inadvertently touch the rebar, causing its position within the hole to change. Therefore, a positioning device is needed to fix the rebar in place, keeping it centered in the drilled hole. Existing rebar anchoring positioning devices have a simple structure and can only position and fix one rebar at a time, failing to meet the need for simultaneous positioning and fixing of multiple rebars in the anchoring area. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model aims to provide a novel rebar positioning device. This device can simultaneously position and fix multiple rebars, and can be effectively adjusted according to the number and position of the rebars, thereby ensuring that the rebars are stably kept in the center of the drill hole and avoiding displacement caused by external force, thus significantly improving the quality of rebar installation.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A novel rebar positioning device includes a square frame and a clamp for holding and fixing the rebar. Multiple adjusting frames are slidably mounted in the middle of the square frame, and multiple positioning seats are detachably mounted on the adjusting frames in the front-back direction. The clamp is mounted on each positioning seat. Each adjusting frame includes two sliding sleeves and two parallel positioning rods. The ends of the two positioning rods are vertically fixed to the corresponding sliding sleeves. The sliding sleeves are slidably fitted onto the front and rear frames of the square frame and fixed with fasteners. The positioning seats have symmetrically arranged snap-fit ​​plates on their left and right sides. One side of each snap-fit ​​plate engages with a corresponding positioning rod, and the other side of each snap-fit ​​plate has a horizontally fixed sliding rod that slides into a hole on the side wall of the positioning seat. The positioning seat also has a connecting rod fixing assembly for pressing and fixing the snap-fit ​​plates against the positioning rods.

[0006] Preferably, the fixture adopts a triangular chuck structure, which is vertically installed in the middle of the positioning seat.

[0007] Preferably, the square frame is fixed with fixing plates on the left and right sides, and screws are installed in the through holes on the fixing plates.

[0008] Preferably, the fastener includes a locking bolt that passes through the sliding sleeve and abuts against the square frame.

[0009] Preferably, the snap-fit ​​plate is a U-shaped plate, with the opening of the U-shaped plate horizontally positioned away from the positioning seat; the positioning rod is snapped into the U-shaped plate.

[0010] Preferably, two sets of the connecting rod fixing assemblies are symmetrically arranged on the front and rear sides of the positioning seat.

[0011] Preferably, the connecting rod fixing assembly includes a movable block, a screw, and two connecting rods. The screw is vertically rotatably mounted on the side of the positioning seat, the movable block is vertically slidably mounted on the side of the positioning seat and threaded onto the screw, the upper ends of the two connecting rods are respectively rotatably connected to the left and right sides of the movable block, and the lower ends of the connecting rods are inclined downward and rotatably connected to the snap-fit ​​plate; the upper end of the screw is provided with a screwing part.

[0012] Preferably, the screwing part uses a hexagonal bolt head or a hand-tightening bolt head.

[0013] Preferably, the side of the positioning seat is provided with a vertical groove, and the moving block is provided with a locking part near the positioning seat, the locking part being vertically slidably locked in the groove.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. This application allows for the installation of a corresponding number of positioning seats on the adjustment frame according to the number of steel bars that need to be fixed in the rebar installation area. By moving the adjustment frame left and right on the square frame and the fixed position of the positioning seats on the adjustment frame, the device can be adapted to the simultaneous positioning of multiple steel bars, thereby significantly improving the efficiency of rebar installation.

[0016] 2. This application allows for quick adjustment of the horizontal position of each set of positioners in the left-right direction by sliding the sliding sleeve on the front and rear edges of the square frame and fixing it with locking bolts. This makes it very convenient to use.

[0017] 3. When installing the positioning seat of this application, the U-shaped plates on both sides can be clamped onto the positioning rod first. Then, according to the position of the anchoring hole, the front and rear position of the positioning seat on the positioning rod can be adjusted so that the fixing device is aligned with the hole below. Then, the positioning seat can be locked using the connecting rod fixing assembly so that the clamping plate is firmly abutted against the positioning rod, thereby significantly improving the installation efficiency of the fixing device of this application.

[0018] 4. After aligning the fixture with the drilling position, this application rotates the screw by the screw-tightening part, causing the moving block to move vertically downward, which drives the connecting rods on both sides to rotate and swing. Then, under the sliding limit of the sliding rod, the snap-fit ​​plates on both sides are pushed outward, so that the snap-fit ​​plates are stably abutted against the positioning rod, thereby realizing the rapid fixed installation of the positioning seat and significantly improving the efficiency of rebar planting.

[0022] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of application of this utility model.

[0023] like Figure 1-3 As shown, this utility model proposes a novel rebar positioning device, including a square frame 1 and a clamping device 4 for holding and fixing the rebar. Fixing plates 11 are fixed on the left and right sides of the square frame 1, and screws are installed in the through holes on the fixing plates 11. In use, the square frame 1 is placed at the pre-drilled rebar area, and the screws are inserted through the through holes in the fixing plates 11 to fix the square frame 1 above the rebar area, thus providing stable support for the rebar positioning.

[0024] Multiple adjusting brackets 2 are slidably mounted on the middle of the square frame 1. Multiple positioning seats 3 are detachably mounted on the adjusting brackets 2 along the length direction (i.e., the front-to-back direction) of the positioning rod 22. Corresponding fixing devices 4 are installed in the mounting holes in the middle of the positioning seats 3. In this embodiment, the fixing device 4 adopts the triangular chuck of the prior art. The usage method and structural principle of the triangular chuck are well known to those skilled in the art and will not be described in detail here.

[0025] According to the number of steel bars that need to be fixed in the rebar planting area, the present application can install a corresponding number of positioning seats 3 on the adjustment frame 2. By moving the position of the adjustment frame 2 on the square frame 1 and the fixed position of the positioning seats 3 on the adjustment frame 2, the device can be adapted to the simultaneous positioning of multiple steel bars, thereby significantly improving the efficiency of rebar planting construction.

[0026] Specifically, the adjusting frame 2 includes two sliding sleeves 21 and two parallel positioning rods 22. The ends of the two positioning rods 22 are vertically fixed to the corresponding sliding sleeves 21. The sliding sleeves 21 slide left and right on the front and rear edges of the square frame 1 and are fixed by fasteners. In this embodiment, the fasteners are locking bolts 23, which penetrate vertically downward through the sliding sleeves 21 and abut against the square frame 1.

[0027] This application allows for quick adjustment of the horizontal position of each set of positioners in the left-right direction by sliding the sliding sleeve 21 on the front and rear edges of the square frame 1 and fixing it with the locking bolt 23. This makes it very convenient to use.

[0028] The positioning base 3 has symmetrically arranged snap-fit ​​plates 51 on its left and right sides. One side of the snap-fit ​​plate 51 cooperates with the corresponding positioning rod 22, and the other side of the snap-fit ​​plate 51 has a horizontally fixed sliding rod 511, which is slidably inserted into the insertion hole on the side wall of the positioning base 3. Specifically, in this embodiment, the snap-fit ​​plate 51 is a U-shaped plate, with the opening of the U-shaped plate horizontally outward away from the positioning base 3; the positioning rod 22 is snapped into the U-shaped plate. The positioning base 3 is also provided with a connecting rod fixing assembly for pressing and fixing the snap-fit ​​plate 51 against the positioning rod 22.

[0029] When installing the positioning seat 3 of this application, the U-shaped plates on both sides can be first clamped onto the positioning rod 22. Then, according to the position of the anchoring hole, the front and rear positions of the positioning seat 3 on the positioning rod 22 can be adjusted so that the fixing device 4 is aligned with the hole below. Then, the positioning seat 3 can be locked using the connecting rod fixing assembly so that the clamping plate 51 is firmly abutted against the positioning rod 22, thereby significantly improving the installation efficiency of the fixing device 4 of this application.

[0030] In this embodiment, two sets of connecting rod fixing assemblies are symmetrically arranged on the front and rear sides of the positioning seat 3. Each connecting rod fixing assembly includes a moving block 53, a screw 55, and two connecting rods 52. The screw 55 is vertically rotatably mounted on the side of the positioning seat 3. The moving block 53 is vertically slidably mounted on the vertical slide rail 531 on the side of the positioning seat 3 and threaded onto the screw 55. The upper ends of the two connecting rods 52 are rotatably connected to the left and right sides of the moving block 53, respectively, and the lower ends of the connecting rods 52 are inclined downward and rotatably connected to the locking plate 51. The upper end of the screw 55 is provided with a screwing part 54. The side of the positioning seat 3 is vertically provided with a sliding groove, and the moving block 53 is provided with a locking part near the side of the positioning seat 3. The locking part is vertically slidably locked in the sliding groove. In this embodiment, the sliding groove is a T-shaped groove, and the locking part adopts a T-shaped block structure that cooperates with the sliding groove. The sliding cooperation between the sliding groove and the locking part can improve the stability of the moving block 53 when moving. The screwing part 54 uses a hexagonal bolt head or a hand-tightening bolt head, which can improve the convenience of adjusting the connecting rod fixing assembly.

[0031] After aligning the fixing device 4 with the drilling position, the screw 55 is rotated by the screwing part 54, causing the moving block 53 to move vertically downward, which drives the connecting rods 52 on both sides to rotate and swing. Then, under the sliding limit of the sliding rod 511, the snap-fit ​​plates 51 on both sides are pushed outward, so that the snap-fit ​​plates 51 are stably abutted against the positioning rod 22, thereby realizing the rapid fixed installation of the positioning seat 3 and significantly improving the efficiency of rebar planting.

[0032] When using this utility model, adjust the position of the sliding sleeve 21 on the square frame 1 by sliding it left and right and lock it with the locking bolt 23; then, clamp the U-shaped plates on both sides onto the positioning rod 22, adjust the position of the positioning seat 3 so that the fixing device 4 is aligned with the lower drill hole, and lock the positioning seat 3 by adjusting the screw part 54 of the connecting rod fixing assembly; finally, after passing the steel bar through the triangular chuck and inserting it vertically into the center of the drill hole, lock it with the triangular chuck.
