Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a portable rebar spacing positioning clamp. Background Technology

[0002] In the construction of pile foundations and columns in building engineering, several steel bars need to be enclosed in a square or circle, and then these steel bars are positioned and tied with stirrups to form a steel cage before concrete can be poured. In order to ensure the accuracy of the binding position of each steel bar on the stirrup, the steel bars need to be pre-positioned before binding the stirrup.

[0003] A search revealed that patent CN219805310U discloses a tool for positioning the main reinforcement bars of a steel cage. Each reinforcement bar clamp can hold one reinforcement bar, and multiple reinforcement bar clamps are evenly distributed along the circumference of the installation ring frame, thereby clamping and fixing all the main reinforcement bars of the steel cage. This means that only multiple people are needed to cooperate when installing the reinforcement bars, and no auxiliary personnel are needed to support the main reinforcement bars when welding them to the inner ring reinforcement bars, saving labor costs. Furthermore, multiple people can weld multiple main reinforcement bars and inner ring reinforcement bars simultaneously, improving welding efficiency.

[0004] While the above-mentioned solution can position and clamp the main reinforcement bars of the steel cage using the steel bar clamps set on the installation ring frame, it is too bulky and lacks portability. Furthermore, since the installation ring frame consists of a fixed arc frame and two movable arc frames, with the two ends of the fixed arc frame hinged to the corresponding movable arc frames, and one end of one movable arc frame being engaged with the other movable arc frame via a hinged connector, the presence of the hinge and connector makes it inconvenient to place the steel bar clamps at any position on the installation ring frame in actual use. It is also inconvenient to increase the number of steel bar clamps on the fixed arc frame and the movable arc frames with hinged connectors at the ends. As a result, this device is not suitable for steel cages with different numbers of main reinforcement bars and needs improvement. Utility Model Content

Detailed Implementation

[0018] 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.

[0019] Please see Figures 1-3 In this embodiment of the utility model, a portable rebar spacing positioning clamp includes several clamp components. Each clamp component includes a cylindrical connecting sleeve 1. A connecting post 2 is fixedly installed on the top of the connecting sleeve 1. An insertion port adapted to the connecting post 2 is opened at the bottom of the connecting sleeve 1. A first hand-tightening bolt 6 is installed on the outer wall of the connecting sleeve 1 through a threaded hole. A scale strip 4 is provided at the top of the outer peripheral wall of the connecting sleeve 1. An indicator 5 is provided at the bottom of the outer peripheral wall of the connecting sleeve 1. A sleeve 12 is fixedly installed on the outer peripheral wall of the connecting sleeve 1. An inner rod 13 is installed through the sleeve 12 at an adjustable length at the end away from the connecting sleeve 1. A clamping mechanism for the rebar 21 is installed at the end of the inner rod 13 outside the sleeve 12.

[0020] By adopting the above-mentioned solution, this utility model allows for the selection of a corresponding number of clamping components based on the number of main reinforcing bars in the steel cage. Then, by using the connection of the connecting column 2 and the socket, the connecting sleeves 1 of each clamping component are connected sequentially. Next, by using the cooperation of the indicator 5 and the scale bar 4 to match the included angle between the sleeves 12 of each clamping component with the distribution position of the reinforcing bars 21 in the steel cage, the first hand-tightening bolt 6 is tightened to fix the adjacent connecting column 2. Then, the length of the inner rod 13 extending from the sleeve 12 is adjusted, and the corresponding reinforcing bar 21 is locked using the clamping mechanism. This completes the positioning of each reinforcing bar 21. The operation is simple and convenient, and each clamping component can be disassembled and carried, occupying little space and making it more portable.

[0021] Specific combination Figure 1 and Figure 3 In one embodiment of the present invention, the clamping mechanism includes a clamping seat 18, one end of which is fixedly mounted with a screw 17. The inner rod 13 is located outside the sleeve 12 and has a threaded hole 16 adapted to the screw 17. The screw 17 is connected to the threaded hole 16. The end of the clamping seat 18 away from the screw 17 is fitted with a third hand-tightening bolt 20 through a threaded hole. The inner wall of the clamping seat 18 away from the third hand-tightening bolt 20 has a clamping groove 19.

[0022] After placing the reinforcing bar 21 into the clamping groove 19, tighten the third hand-tightening bolt 20 so that its threaded end abuts against the surface of the reinforcing bar 21. The reinforcing bar 21 can then be locked in the clamping seat 19 using the third hand-tightening bolt 20. The operation is simple and convenient. Through the cooperation of the threaded hole 16 and the screw 17, it is easy to fine-tune the distance between the clamping seat 18 and the connecting sleeve 1, thereby adapting to the positioning of the main reinforcing bars of different sizes of reinforcing cages.

[0023] Specific combination Figure 1 and Figure 3 In one embodiment of the present invention, a second hand-tightening bolt 14 is installed on the outer wall of the sleeve 12 near its opening end through a threaded hole, and a plurality of positioning holes 15 are equally spaced on the outer wall of the inner rod 13, the positioning holes 15 being adapted to the second hand-tightening bolt 14.

[0024] By inserting the second hand-tightening bolt 14 into different positioning holes 15, the length of the inner rod 13 extending out of the sleeve 12 can be positioned. By threading the second hand-tightening bolt 14 into the sleeve 12 and tightening it, the reliability of the connection between the second hand-tightening bolt 14 and the sleeve 12 can be ensured.

[0025] Specific combination Figure 2In one embodiment of the present invention, a pressure block 8 is slidably installed on the inner wall of the connecting sleeve 1 through the sliding groove 7. The pressure block 8 is movably sleeved on the end of the first hand-tightening bolt 6.

An annular groove 3 is provided on the outer peripheral wall of the connecting column 2. The groove width of the annular groove 3 is adapted to the pressure block 8.

[0026] By cooperating with the pressure block 8 and the annular groove 3, after rotating the first hand-tightening bolt 6 to insert the pressure block 8 into the annular groove 3, the connecting post 2 can be prevented from falling out of the connecting sleeve 1. The setting of the rubber pad 9 can improve the locking effect of the pressure block 8 on the connecting post 2 and prevent the pressure block 8 from slipping in the annular groove 3.

[0027] Specific combination Figure 2 Based on the previous embodiment, the first hand-tightening bolt 6 is provided with an annular guide groove 10 on the outer wall inside the pressure block 8, and a positioning pin 11 is fixedly installed at the corresponding position of the outer wall of the pressure block 8 and the annular guide groove 10, with one end of the positioning pin 11 located inside the annular guide groove 10.

[0028] The annular guide groove 10 and the positioning pin 11 can lock the end of the first hand-tightening bolt 6 into the pressure block 8 without interfering with the rotation of the first hand-tightening bolt 6 in the locking block 8.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
