Description

Technical Field

[0001] This utility model belongs to the field of rebar spacing control, and specifically relates to a device for controlling rebar spacing. Background Technology

[0002] In construction engineering, the arrangement and spacing control of reinforcing bars are crucial for ensuring structural strength and stability. Currently, most commonly used methods for measuring reinforcing bar spacing involve manual measurement using tape measures or rulers, which are difficult to guarantee in terms of accuracy and are greatly affected by human factors. Therefore, we propose a reinforcing bar spacing control caliper to solve this problem.

[0003] According to Chinese Patent No. CN222670934U, a rebar spacing control caliper is disclosed, including a rectangular handle. A measuring plate is fixedly connected to one side of the rectangular handle, and a second scale is provided on the outer side of the measuring plate. The measuring plate is provided with two measuring components, and a limit mechanism is provided on the measuring components. The limit mechanism includes a measuring block, on which a first scale is provided, and a handle is rotatably connected to one side of the measuring block. By rotating the handle, since a bidirectional lead screw is fixedly connected to one end of the handle, and the threads on the bidirectional lead screw are arranged in opposite directions, rotating the handle drives the bidirectional lead screw to rotate, thereby clamping the two clamping blocks connected by the outer threads to the outside of the rebar, completing the limit of the device. It can also measure the diameter of the rebar, realizing the dual-purpose function of the device.

[0004] As can be seen from the above structure, when the two measuring components are clamped on the outside of the two reinforcing bars, the above device can clamp the outside of the two reinforcing bars and measure their spacing at the same time, which can accurately control the spacing of the reinforcing bars during construction. However, the above device is particularly inconvenient when adjusting the spacing between the two measuring blocks. It is necessary to turn the limit rod to loosen the measuring blocks and then adjust them, which is a rather complicated process. Therefore, a device for controlling the spacing of reinforcing bars is proposed. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a device for controlling the spacing of reinforcing bars, so as to solve the problems mentioned in the background art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A device for controlling the spacing of reinforcing bars includes a measuring frame, a bidirectional screw is rotatably connected inside the measuring frame, threaded parts are rotatably connected to both sides of the outer surface of the bidirectional screw, a positioning component is provided at the lower end of the threaded parts, the threaded parts are slidably inserted into the inner side of the measuring frame, a measuring through groove is provided at the upper end of the measuring frame, and scales are provided on both sides of the measuring through groove at the upper end of the measuring frame.

[0008] As a preferred technical solution, the positioning component includes a positioning groove disposed at the lower end of the threaded part, a positioning screw is rotatably connected inside the positioning groove, positioning elements are rotatably connected to both sides of the outer surface of the positioning screw, a clamping block is fixedly connected to the other end of the positioning element, and a rotating handle is fixedly connected to the other end of the positioning screw.

[0009] As a preferred technical solution, a turntable is fixedly connected to the other end of the bidirectional screw, the outer ring of a bearing is fixedly connected to the outer side of the turntable, a handle is fixedly connected to the inner ring of the bearing, and a protective pad is provided on the outer surface of the handle.

[0010] As a preferred technical solution, the upper ends of the measuring frame are fixedly connected to both sides of the measuring frame, and a handle is fixedly connected to the outer surface of the fixed rod, and an anti-slip pad is fixedly connected to the outer surface of the handle.

[0011] As a preferred technical solution, a connecting rod is fixedly connected to the other end of the measuring frame, and a connecting ring is fixedly connected to the other end of the connecting rod. The connecting ring is fixedly connected to the end of the connecting rod by screws.

[0012] As a preferred technical solution, the inner sides of the measuring frame are slidably inserted into the threaded parts, and guide holes are provided on both sides of the threaded parts.

[0013] As a preferred technical solution, a measuring slide rod is fixedly connected to the upper end of the threaded part, the measuring slide rod is slidably connected to the measuring through groove, and a measuring pointer is fixedly connected to the other end of the measuring slide rod through the measuring through groove.

[0014] In summary, the present invention has the following main advantages:

[0015] First, by rotating the bidirectional screw, since the threads on both sides of the outer surface of the bidirectional screw turn in opposite directions and the threaded parts slide into the inner side of the measuring frame, the rotation of the bidirectional screw will drive the threaded parts on both sides to move closer or further away synchronously along the screw axis. The positioning component at the lower end of the threaded part moves with the threaded part and can fit against both sides of the object to be measured to achieve positioning. At the same time, the scale on both sides of the measuring slot at the upper end of the measuring frame can intuitively read the distance between the threaded parts on both sides, thereby completing the measurement of the spacing between the reinforcing bars. The positioning components on both sides are adjusted synchronously through the bidirectional screw drive, eliminating the need for separate adjustments, which greatly shortens the positioning and measurement time and reduces the complexity of operation. At the same time, the thread adjustment measurement accuracy is high, the displacement of the bidirectional screw drive is stable, and with the precise scale of the scale, the error of manual positioning and reading can be reduced, ensuring the accuracy of the measurement results.

[0016] Secondly, rotating the outer rotating handle can drive the positioning screw to rotate. Since the threads on both sides of the outer surface of the positioning screw turn in opposite directions, and the positioning parts are limited by the positioning groove and cannot rotate, when the positioning screw rotates, it will drive the positioning parts on both sides to move synchronously towards or away from each other along the groove. The clamping block at the other end of the positioning part moves with the positioning part, and can adjust the spacing according to the size of the steel bar to achieve tight clamping on both sides of the steel bar, thereby completing the stable positioning of the steel bar during the measurement process and providing a reliable benchmark for subsequent dimensional measurement.

[0022] Example

[0023] refer to Figures 1 to 4 The present embodiment of a device for controlling the spacing of reinforcing bars includes a measuring frame 1. A bidirectional screw 2 is rotatably connected inside the measuring frame 1. Threaded parts 3 are rotatably connected to both sides of the outer surface of the bidirectional screw 2. A positioning component 4 is provided at the lower end of the threaded parts 3. The threaded parts 3 and the inner side of the measuring frame 1 are slidably inserted into each other. A measuring through groove 5 is opened at the upper end of the measuring frame 1. A scale 6 is provided on both sides of the measuring through groove 5 at the upper end of the measuring frame 1.

[0024] refer to Figures 1-4The positioning component 4 includes a positioning groove 41 located at the lower end of the threaded component 3. A positioning screw 42 is rotatably connected inside the positioning groove 41. Positioning components 43 are rotatably connected to both sides of the outer surface of the positioning screw 42. A clamping block 44 is fixedly connected to the other end of the positioning component 43. A rotating handle 45 is fixedly connected to the other end of the positioning screw 42. The positioning screw 42 can be driven to rotate by rotating the rotating handle 45 on the outer side. Since the threads on both sides of the outer surface of the positioning screw 42 turn in opposite directions and the positioning components 43 are limited by the positioning groove 41 and cannot rotate, when the positioning screw 42 rotates, it will drive the positioning components 43 on both sides to move synchronously towards or away from each other along the groove. The clamping block 44 at the other end of the positioning component 43 moves with the positioning component 43, and the spacing can be adjusted according to the size of the steel bar to achieve tight clamping of both sides of the steel bar.

[0025] refer to Figure 2 The other end of the bidirectional screw 2 is fixedly connected to a turntable 13. The outer ring of a bearing 14 is fixedly connected to the outer side of the turntable 13, and a handle 15 is fixedly connected to the inner ring of the bearing 14. A protective pad is provided on the outer surface of the handle 15. By holding the handle 15, the turntable 13 is rotated, and the rotation of the turntable 13 can drive the bidirectional screw 2 fixedly connected to it to rotate. Thus, the bidirectional screw 2 can be easily rotated with the handle 15 and the turntable 13.

[0026] refer to Figure 2 The upper end of the measuring frame 1 is fixedly connected to two fixed rods 9 on both sides. The outer surface of the fixed rods 9 is fixedly connected to the handles 10, and the outer surface of the handles 10 is fixedly connected to the anti-slip pads. When it is necessary to move the measuring frame 1 or adjust its position, the operator can directly hold the handles 10 and apply force through the handles 10 to easily push or move the measuring frame 1 without directly contacting the measuring components of the measuring frame 1, thus avoiding interference with the measurement accuracy.

[0027] refer to Figure 2 The other end of the measuring frame 1 is fixedly connected to a connecting rod 11, and the other end of the connecting rod 11 is fixedly connected to a connecting ring 12. The connecting ring 12 is fixedly connected to the end of the connecting rod 11 by screws. When the measuring frame 1 is not in use, the operator can hang the entire measuring frame 1 on a wall hook, shelf rod or other support structure through the connecting ring 12 to avoid the space occupation and component collision problems caused by placing the measuring frame 1 directly on the ground or table.

[0028] refer to Figure 1The measuring frame 1 has two sides inside that are slidably connected to the threaded parts 3. Both sides of the threaded parts 3 are provided with guide holes 7. Both sides of the measuring frame 1 are fixedly connected with guide rods 8, which are slidably connected to the guide holes 7. When the bidirectional screw 2 drives the threaded parts 3 to move along the inside of the measuring frame 1, the guide rods 8 always slide synchronously in the guide holes 7. On the one hand, this restricts the threaded parts 3 from rotating with the bidirectional screw 2, ensuring that the threaded parts 3 only move smoothly along the axial direction. On the other hand, through the cooperation of the rods and holes, it counteracts the lateral offset or shaking that may occur when the threaded parts 3 move. Ultimately, it ensures that the threaded parts 3 on both sides drive the positioning components 4 to move synchronously and linearly, providing structural support for the accuracy of subsequent part positioning and dimensional measurement.

[0029] refer to Figure 2 A measuring slide rod 16 is fixedly connected to the upper end of the threaded part 3. The measuring slide rod 16 is slidably connected to the measuring through groove 5. The other end of the measuring slide rod 16 passes through the measuring through groove 5 and is fixedly connected to a measuring pointer 17. When the bidirectional screw 2 drives the threaded part 3 to move along the inner side of the measuring frame 1, the measuring slide rod 16 will slide synchronously along the measuring through groove 5 with the threaded part 3. Since the other end of the measuring slide rod 16 passes through the measuring through groove 5 and is fixed with the measuring pointer 17, the pointer will move synchronously with the slide rod and point to the scale 6 on both sides of the measuring through groove 5. The operator can directly read the distance between the two threaded parts 3 by the precise pointing of the pointer on the scale 6 without the need for additional tools. This effectively avoids manual estimation errors and provides an intuitive and accurate reading basis for part size measurement.

[0030] Operating principle and advantages: During use, by adjusting the device and rotating the bidirectional screw 2, the threads on both sides of the outer surface of the bidirectional screw 2 rotate in opposite directions, and the threaded parts 3 are slidably inserted into the inner side of the measuring frame 1. As the bidirectional screw 2 rotates, it drives the threaded parts 3 on both sides to move synchronously closer or further away along the screw axis. The positioning component 4 at the lower end of the threaded parts 3 moves with the threaded parts 3, allowing it to conform to both sides of the object to be measured for positioning. Simultaneously, the scale 6 on both sides of the measuring groove 5 at the upper end of the measuring frame 1 allows for a direct reading of the distance between the threaded parts 3 on both sides, thus completing the measurement of the spacing between the reinforcing bars. Then, by inserting the reinforcing bar into the inner side of the clamping block 44... By rotating the outer rotating handle 45, the positioning screw 42 can be driven to rotate. Since the threads on both sides of the outer surface of the positioning screw 42 turn in opposite directions, and the positioning part 43 is limited by the positioning groove 41 and cannot rotate, when the positioning screw 42 rotates, it will drive the positioning parts 43 on both sides to move synchronously towards or away from each other along the groove. The clamping block 44 at the other end of the positioning part 43 moves with the positioning part 43, and can adjust the spacing according to the size of the steel bar to achieve tight clamping on both sides of the steel bar, thereby completing the stable positioning of the steel bar during the measurement process and providing a reliable benchmark for subsequent size measurement. Thus, after the adjustment is completed, the spacing of multiple steel bars can be adjusted.
