Description

Technical Field

[0001] This utility model relates to the field of concrete frames, and in particular to a rebar positioning clamp for concrete frame structures. Background Technology

[0002] A concrete frame is a load-bearing skeleton structure formed by reinforced concrete beams and columns connected by joints. The reinforcing bars in its load-bearing system act like the "nerves" of the skeleton, requiring precise positioning to ensure structural strength. Reinforcing bar positioning clamps are crucial tools for this purpose. Like a "coordinate ruler" for the reinforcing bars, they use slots, limiting claws, bolts, and other components to fix the main reinforcing bars and stirrups of beams and columns according to the designed spacing and position before concrete pouring, preventing displacement of the reinforcing bars due to vibration and concrete flow during pouring. Some of these clamps use curved steel plates to clamp column reinforcing bars and control the protective layer, while others use a grid-shaped combination of bolts to position the beam reinforcing bar spacing. This ensures that the reinforcing bar arrangement meets mechanical requirements and allows for repeated use, making them core auxiliary tools for ensuring the accuracy of reinforcing bar positioning during frame structure construction.

[0003] However, current rebar positioning clamps for concrete frame structures have the following drawbacks: First, they are poorly adaptable to rebars of different spacings and diameters, making it difficult to meet diverse positioning needs. They lack versatility and ease of disassembly, affecting subsequent use. Second, they typically lack support or have weak support stability, making them prone to swaying during positioning, and the support structure is inconvenient to store.

[0004] In response to this technical problem, this application proposes a rebar positioning clamp for a concrete frame structure. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art and to propose a rebar positioning clamp for concrete frame structures. The aim is to enable the device to position rebars with different spacings, fix rebars with different diameters, improve the versatility of the device, make the clamp easy to disassemble for subsequent use, and enable the clamp to support the rebars, thereby improving the stability when positioning the rebars.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A rebar positioning clamp for a concrete frame structure includes a side plate. A groove is formed on the front side of the side plate, and two sliders are slidably connected inside the groove. A first bidirectional screw is rotatably connected inside the groove, and the sliders are threaded onto the outer wall of the first bidirectional screw. A first knob is rotatably connected to the right side of the side plate via a damping shaft. The right end of the first bidirectional screw is fixedly connected inside the first knob. A clamping assembly is provided on the front side of the slider to clamp the rebar. Two support rods are fixedly connected to the rear side of the side plate, and a support assembly is provided on the rear side of the support rods to support the side plate.

[0008] Furthermore, the clamping assembly includes a groove formed on the front side of the slider, two adjusting blocks are slidably connected inside the groove, and a clamping ring is connected to the front side of the adjusting block by a torsion spring, and a bolt is inserted between the two clamping rings.

[0009] Furthermore, a second bidirectional screw is rotatably connected inside the groove, the adjusting block is threaded onto the outer wall of the second bidirectional screw, one side of the slider is rotatably connected to a second knob via a damping shaft, and one end of the second bidirectional screw is fixedly connected inside the second knob.

[0010] Furthermore, the support assembly includes a leg rotatably connected to the bottom end of the support rod, a round rod fixedly connected inside the support rod, and a slide block slidably connected to the outer wall of the round rod, the slide block being slidably connected inside the support rod.

[0011] Furthermore, the slide and the support leg are connected by a connecting rod, one end of which is rotatably connected to the inside of the support leg, and the other end of which is rotatably connected to the inside of the slide.

[0012] Furthermore, multiple fixing plates are fixedly connected to both sides of the support rod, and fixing blocks are connected to both sides of the slide block via torsion springs. A fixing rod is inserted between the fixing plates and the fixing blocks.

[0013] Furthermore, two rubber strips are fixedly connected to the front side of both the groove and the recess, and the upper and lower rubber strips are in contact with each other.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the distance between the two sliders is adjusted by the first bidirectional screw, so that the device can position steel bars with different spacings. The distance between the two clamping rings is adjusted by the second bidirectional screw, so that the device can fix steel bars of different diameters, improving the versatility of the device. At the same time, by allowing the clamping rings to rotate, the clamping rings can be easily removed from the steel bars, making the clamp easy to disassemble and convenient for subsequent use.

[0016] 2. In this utility model, the sliding block causes the connecting rod to rotate with the outrigger, so that the outrigger rotates to the ground and forms an oblique brace with the connecting rod to support the side plate. This allows the clamp to support the reinforcing bar, improving the stability when positioning the reinforcing bar. The fixing plate is fixed by inserting the fixing rod into the fixing plate and fixing block, thereby fixing the sliding block and fixing the position of the outrigger. Attached Figure Description

[0025] 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.

[0026] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 This utility model provides an embodiment of a rebar positioning clamp for a concrete frame structure, comprising a side plate 1. A groove is formed on the front side of the side plate 1, with two sliders 3 slidably connected inside the groove. A first bidirectional screw 14 is rotatably connected inside the groove, and the sliders 3 are threaded onto the outer wall of the first bidirectional screw 14. A first knob 5 is rotatably connected to the right side of the side plate 1 via a damping shaft. The right end of the first bidirectional screw 14 is fixedly connected inside the first knob 5. Rotating the first knob 5 causes the first bidirectional screw 14 to rotate, driving the two sliders 3 to slide in relative or opposite directions, thereby adjusting the distance between the two sliders 3, allowing the device to position rebars with different spacing. Two support rods 6 are fixedly connected to the rear side of the side plate 1, as shown in the figure. Figure 4 and Figure 5 The slider 3 has a groove on its front side, and two adjusting blocks 18 are slidably connected inside the groove. The front side of the adjusting blocks 18 is connected to a clamping ring 4 via a torsion spring. A bolt 16 is inserted between the two clamping rings 4. A second bidirectional screw 15 is rotatably connected inside the groove. The adjusting blocks 18 are threaded onto the outer wall of the second bidirectional screw 15. A second knob 17 is rotatably connected to one side of the slider 3 via a damping shaft. One end of the second bidirectional screw 15 is fixedly connected inside the second knob 17. By rotating the second knob 17, the second bidirectional screw 15 is rotated, causing the second bidirectional screw 15 to drive the two adjusting blocks 18 to slide in relative or opposite directions, thereby adjusting the distance between the two clamping rings 4. This allows the device to fix steel bars of different diameters, improving the versatility of the device. By inserting the bolt 16 between the two clamping rings 4 and screwing a nut onto the bolt 16, the bolt 16 is prevented from detaching from the clamping ring 4. Rotating the clamping ring 4 allows it to detach from the steel bar, making the clamp easy to disassemble and convenient for subsequent use.

[0027] Reference Figure 2 , Figure 3 and Figure 6The bottom end of the support rod 6 is rotatably connected to the support leg 8. A round rod 9 is fixedly connected inside the support rod 6. A slide block 10 is slidably connected to the outer wall of the round rod 9. The slide block 10 is slidably connected inside the support rod 6. The slide block 10 and the support leg 8 are connected by a connecting rod 7. One end of the connecting rod 7 is rotatably connected to the inside of the support leg 8, and the other end of the connecting rod 7 is rotatably connected to the inside of the slide block 10. Multiple fixing plates 12 are fixedly connected to both sides of the support rod 6. Fixing blocks 11 are connected to both sides of the slide block 10 by torsion springs. Fixing rods 13 are inserted between the fixing plates 12 and the fixing blocks 11. The slide block... 10 causes the connecting rod 7 to rotate with the outrigger 8, so that the outrigger 8 rotates to the ground and forms an oblique brace with the connecting rod 7 to support the side plate 1, so that the clamp can support the steel bar and improve the stability when positioning the steel bar. Alternatively, the outrigger 8 can be rotated to one side of the support rod 6 to fold it onto the support rod 6 for storage. The fixing block 11 is rotated to rotate it between the two fixing plates 12, and the fixing rod 13 is inserted into the fixing plate 12 and the fixing block 11 to fix the fixing plate 12, thereby fixing the slide 10 and fixing the position of the outrigger 8. Two rubber strips 2 are fixedly connected to the front side of both the slide and the groove. The upper and lower rubber strips 2 are in contact with each other, and the slide and the groove are sealed by the two rubber strips 2 that can be in contact with each other, thereby protecting the first bidirectional screw 14 and the second bidirectional screw 15 and preventing dust and other dirt from contaminating the first bidirectional screw 14 and the second bidirectional screw 15 and affecting them. When the slider 3 or the adjusting block 18 moves to a certain position, the rubber strip 2 will automatically open due to its own elasticity, allowing it to move freely. When the slider 3 or the adjusting block 18 moves to other positions of the rubber strip 2, it will automatically close, thereby sealing the slide and the groove.

[0028] Working principle: First, move the side plate 1 to the side of the rebar to be positioned. Then, rotate the first knob 5 to rotate the first bidirectional screw 14, causing the first bidirectional screw 14 to drive the two sliders 3 to slide in opposite directions, thereby adjusting the distance between the two sliders 3 so that the two sliders 3 are aligned with the two rebars to be positioned. Then, push the side plate 1 to move the rebar between the two clamping rings 4. Then, rotate the second knob 17 to rotate the second bidirectional screw 15, causing the second bidirectional screw 15 to drive the two adjusting blocks 18 to slide in opposite directions, thereby adjusting the distance between the two clamping rings 4 so that the two clamping rings 4 clamp the rebar. Then, screw the nut into the bolt 16 to prevent the bolt 16 from disengaging from the clamping rings 4. Finally, tighten the fixing rod 13 located on the two fixing blocks 11 on the top side. Remove the fixed plate 12 and rotate it to disengage it from the two fixed blocks 11 on the top side. Then slide the slide block 10 to rotate the connecting rod 7 with the support leg 8, so that the support leg 8 rotates to the ground and forms an oblique brace with the connecting rod 7 to support the side plate 1. Then rotate the fixed block 11 to rotate it to the two fixed blocks 11 on the bottom side. Then insert the fixed rod 13 into the fixed block 11 and the fixed plate 12 to fix the fixed plate 12, thereby fixing the slide block 10 and then fixing the support leg 8. After use, first remove the bolt 16 from the two clamping rings 4, then rotate the clamping rings 4 to disengage them from the steel bars so that the clamping rings 4 can be easily disengaged from the steel bars. Then drag the side plate 1 to disengage the clamping rings 4 from the steel bars to complete the disassembly for the next use. The storage process for the support leg 8 is the reverse of the above, and will not be described in detail here.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
