Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a rebar tying bracket that is easy to assemble and disassemble quickly. Background Art

[0002] Binding is the binding of steel reinforcement in the early stages of building construction to facilitate better and safer construction. In actual construction, beam reinforcement binding is generally done manually on site. Due to limited site conditions, the completion of the beam reinforcement cage mainly depends on the workers' skill level, which cannot achieve the effect of the beam flat construction drawings. This results in the actual beam bearing capacity being lower than the design strength requirements. At the same time, manual binding cannot achieve standardized production, which greatly reduces construction efficiency.

[0003] Currently, stirrups are generally used for rebar tying. The stirrup is inserted into the pre-embedded hole or onto the rebar, ensuring full contact between the stirrup and the rebar. After the stirrup is installed, the rebar to be fixed is placed into the stirrup. If necessary, a hammer can be used to gently tap the rebar to achieve a better fixing effect with the stirrup. Since the stirrup rebar cannot be removed and the rebar tying work is extensive, a large number of stirrup rebars are consumed, resulting in high costs. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a rebar tying support that is easy to assemble and disassemble quickly, so as to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rebar tying bracket that is easy to assemble and disassemble quickly, comprising a support frame, two fixed sleeves symmetrically fitted on the outside of each of the two support frames, a connecting rod welded between the two sets of fixed sleeves, a sliding sleeve fitted on the outside of the connecting rod, support sleeves symmetrically fitted on the outside of the two support frames, a limiting block welded to one end of each sliding sleeve and support sleeve, a clamping block slidably connected to one side of each limiting block, a slider welded to one end of each clamping block, a sliding groove formed inside the limiting block, and a pull rod welded through the limiting block to one side of each slider.

[0006] Preferably, one end of the pull rod is provided with a through groove, and one side of both the sliding sleeve and the support sleeve is connected to a rotating shaft through a bearing.

[0007] Preferably, a retaining block is welded to the side of the rotating shaft away from the bearing, and the end of the retaining block near the through groove is set in an arc shape.

[0008] Preferably, the slider is configured as a "T" shaped structure, and the clamping block and the limiting block form a sliding structure through the slider and the groove.

[0009] Preferably, the locking block and the limiting block form a rotating structure through a rotating shaft, and the pull rod and the limiting block form an engaging structure through the locking block and the through groove.

[0010] Preferably, multiple limiting grooves are equally spaced on one side of both support frames, and cavities are formed inside both the support sleeve and the sliding sleeve.

[0011] Preferably, a pull rod is slidably connected inside the cavity, and a support spring is welded between the pull rod and the cavity.

[0012] Preferably, the pull rod and the cavity form an elastic structure through a support spring.

[0013] Preferably, the support sleeve and the support frame form an engaging structure through a pull rod and a limiting groove.

[0014] Preferably, the sliding sleeve and the connecting rod form an engaging structure with the limiting groove via a pulling rod.

[0015] Beneficial effects

[0016] In summary, the present invention has the following main advantages:

[0017] 1. Existing rebar tying supports generally use stirrup rebars, which can only be fixed at the rebar tying point and cannot be removed, resulting in high costs. This utility model uses a fixed sleeve, connecting rod, sliding sleeve, limiting block, and clamping block. When the pull rod is pushed, the clamping block moves horizontally away from the limiting block. The rebar is then placed between the limiting block and the clamping block. Pulling the pull rod and rotating the locking block engages with the through groove of the pull rod, thus limiting and clamping the rebar to be tied. After tying, rotating the locking block disengages the pull rod, and pushing the pull rod disassembles the clamped rebar. The support frame can then be moved to perform the same operation on the next rebar to be tied. This achieves the purpose of facilitating quick assembly and disassembly after limiting and tying the rebar, making it easy to reuse.

[0018] 2. Existing rebar tying supports require workers to accurately measure the tying position before moving the supports to the tying location for tying. This results in high labor intensity and reduced construction efficiency. This utility model, through the design of a limiting groove, cavity, pull rod, and support spring, allows for easy adjustment based on the rebar tying position when the position changes. This causes the sliding sleeve and support sleeve to lose their connection with the support frame, allowing the sliding sleeve and support sleeve to be adjusted to the desired position. Releasing the pull rod then engages with the limiting groove, thus facilitating adjustment according to the rebar tying position. Its structure is simple, flexible, and easy to operate.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0026] The embodiments of this utility model will be described below based on its overall structure.

[0027] A rebar tying support that is easy to assemble and disassemble, such as Figure 1 and Figure 2 and Figure 3As shown, the device includes a support frame 1. Two fixed sleeves 2 are symmetrically fitted around the outside of each support frame 1. A connecting rod 3 is welded between the two sets of fixed sleeves 2. A sliding sleeve 4 is fitted around the outside of the connecting rod 3. A clamping block 6 is slidably connected to one side of a limiting block 5. A slider 7 is welded to one end of the clamping block 6. A groove 8 is formed inside the limiting block 5. A pull rod 9, penetrating the limiting block 5, is welded to one end of the slider 7. A through groove 10 is formed at one end of the pull rod 9. A rotating shaft 11 is connected to one side of the sliding sleeve 4 and the support sleeve 13 via a bearing. A locking block 12 is welded to the side of the rotating shaft 11 away from the bearing. The end of the locking block 12 near the through groove 10 is arc-shaped. The locking block 12 and the limiting block 5 are connected by a rotating shaft 11. Shaft 11 forms a rotating structure. Pull rod 9 and limiting block 5 form a locking structure through locking block 12 and through slot 10. When pull rod 9 is pushed, clamping block 6 moves horizontally away from limiting block 5. Then, the reinforcing bar is placed between limiting block 5 and clamping block 6. Pull pull rod 9 again and rotate locking block 12 to lock with through slot 10 of pull rod 9, so that the reinforcing bar to be tied is locked. After tying, locking block 12 can be rotated to release the locking of pull rod 9 and push pull rod 9 to disassemble the clamped reinforcing bar. The support frame 1 can be moved to perform the same operation on the next reinforcing bar to be tied, so as to achieve the purpose of quick assembly and disassembly after locking and tying the reinforcing bar.

[0028] See Figure 1 and Figure 2 It can be seen that the two support frames 1 are symmetrically fitted with support sleeves 13. The sliding sleeve 4 and the support sleeve 13 are both welded to one end with a limiting block 5. The slider 7 is set as a "T" shaped structure. The clamping block 6 and the limiting block 5 form a sliding structure through the slider 7 and the sliding groove 8. The limiting block 5 and the clamping block 6 at the sliding sleeve 4 can clamp the vertical steel bars, and the limiting block 5 and the clamping block 6 at the support sleeve 13 can clamp the horizontal steel bars, which enhances the accuracy of the steel bar binding position and prevents the phenomenon of position deviation.

[0029] See Figure 4 and Figure 5It is known that multiple limiting grooves 14 are equally spaced on one side of both support frames 1. Cavities 15 are opened inside both support sleeve 13 and sliding sleeve 4. A pull rod 16 is slidably connected inside the cavity 15. A support spring 17 is welded to the pull rod 16 and the cavity 15. An elastic structure is formed between the pull rod 16 and the cavity 15 through the support spring 17. The support sleeve 13 and support frame 1 form a locking structure through the pull rod 16 and the limiting groove 14. The sliding sleeve 4 and connecting rod 3 form a locking structure through the pull rod 16 and the limiting groove 14. When the position of the rebar binding changes, the pull rod 16 can be pulled, so that the sliding sleeve 4 and support sleeve 13 lose the locking between the connecting rod 3 and support frame 1, and the sliding sleeve 4 and support sleeve 13 can be adjusted to the required position. Then the pull rod 16 can be released, so that the pull rod 16 and the limiting groove 14 can be locked, thereby achieving the purpose of easy adjustment according to the position of the rebar binding. Its structure is simple and flexible and easy to operate.

[0030] The working principle of this utility model is as follows: When using this rebar tying bracket that is easy to assemble and disassemble, push the pull rod 9 to move the clamping block 6 horizontally away from the limiting block 5. Then, place the vertical rebar between the limiting block 5 and the clamping block 6, pull the pull rod 9, and rotate the locking block 12 to engage with the through groove 10 of the pull rod 9. This allows the clamping block 6 to clamp and limit the rebar. After tying, rotate the locking block 12 to disengage the pull rod 9, and push the pull rod 9 to disassemble the clamped rebar. Then, move the support frame 1 to perform the same process on the next rebar that needs to be tied. The operation facilitates quick assembly and disassembly of the reinforcing bars after they are tied and positioned, preventing positional deviation. When the position of the reinforcing bars changes, the pull rod 16 can be pulled to disengage the sliding sleeve 4 and the support sleeve 13 from the connecting rod 3 and the support frame 1, and the sliding sleeve 4 and the support sleeve 13 can be adjusted to the required position. Then, the pull rod 16 can be released to engage with the limiting groove 14, thereby facilitating adjustment according to the position of the reinforcing bars.
