Description

Technical Field

[0001] This utility model relates to the field of rebar cage processing technology, and in particular to an adjustable clamp for binding large-diameter rebar cages. Background Technology

[0002] In the field of building bridges and high-rise foundation engineering, the binding of large-diameter steel cages generally relies on rotary binding platforms combined with fixed clamps to achieve steel bar positioning. In existing technologies, the clamp structure typically employs rigid claws or hydraulic support modules, fixing the steel bars through pre-sized clamping cavities: for example, using four symmetrically distributed hydraulic telescopic rods to drive the inner support plate to press against the main steel bars of the cage, or using a servo electric cylinder to pull the hooks to encircle the outer edge of the cage. While such structures can improve the clamping stability of single-diameter steel cages, they have significant drawbacks:

[0003] Firstly, the structure has poor adaptability. The clamping cavity size of the fixed clamp is not adjustable. When the diameter of the rebar cage changes beyond the preset value, the original clamp needs to be disassembled and a special component matching the new diameter needs to be replaced. This not only increases the replacement time but also increases the cost of spare clamps.

[0004] Secondly, the lack of dynamic adjustment capability means that traditional clamps cannot adjust the clamping force distribution in real time during the binding process. If the diameter of the steel cage changes abruptly due to welding deformation, the fixing claws will fail due to stress concentration, forcing the operation to be interrupted and repositioned.

[0005] Third, the contact is not firm. The existing fixing structure is difficult to adapt to non-standard steel cages, resulting in a small contact area between the clamp and the steel bar. It is necessary to manually weld temporary supports, and the disassembly process is prone to damaging the anti-corrosion layer on the surface of the steel bar.

[0006] Therefore, there is an urgent need for a clamping system that does not require replacement and is compatible with multi-diameter steel cages, in order to overcome the technical bottlenecks in cost, efficiency and versatility. Utility Model Content

[0007] The purpose of this invention is to provide an adjustable clamp for binding large-diameter steel cages, addressing the aforementioned shortcomings. This solves the problems of poor adaptability of clamp structure, lack of dynamic adjustment capability, and unstable contact in the prior art.

[0008] This utility model is achieved through the following solution:

[0009] An adjustable clamp for binding large-diameter steel cages includes a support plate, a sliding member, and a clamping member. The support plate is provided with a connecting hole that cooperates with an external rotating mechanism. The sliding member is sleeved on both sides of the support plate and can move along the length of the support plate. The clamping member is disposed on the sliding member and can move closer to or away from the support plate.

[0010] Based on the structure of the adjustable clamp for binding large-diameter steel cages described above, the support plate is a cuboid structure, that is, the cross section of the support body and the sliding member is a rectangular structure; the sliding member is provided with a rectangular cavity structure that cooperates with the support body.

[0011] Based on the structure of the adjustable clamp for binding large-diameter steel cages described above, the sliding component includes a sliding sleeve and a support frame. The support frame is symmetrically arranged on both sides of the sliding sleeve at the center position along the length direction of the sliding sleeve, and the support frame is provided with a first threaded hole that mates with the clamping component.

[0012] Based on the structure of the adjustable clamp for binding large-diameter steel cages described above, the support frame is an L-shaped structure, which includes a first connecting plate and a second connecting plate; the first connecting plate is arranged perpendicular to the end face of the sliding member, and the second connecting plate is arranged perpendicularly to the end of the first connecting plate away from the sliding member, and the second connecting plate is arranged parallel to the sliding member.

[0013] Based on the structure of the adjustable clamp for binding large-diameter steel cages described above, the clamping component includes a threaded rod, a rotating handle, a guide rod, a rotating bearing, and a clamping seat. The threaded rod is disposed in a threaded hole in the support frame. The guide rod is disposed on the side of the second connecting plate near the support plate and extends a predetermined distance toward the support plate. The rotating bearing is disposed on the clamping seat, and the clamping seat is also provided with a through hole that mates with the guide rod. The rotating handle is disposed on the threaded rod.

[0014] Based on the structure of the adjustable clamp for binding large-diameter steel cages described above, the clamping base includes a supporting base plate and a contact plate; the supporting base plate is provided with a through hole that mates with a guide rod, the rotating bearing is provided on the end face of the supporting base plate near the second connecting plate, and the contact plate is provided on the end face of the supporting base plate away from the second connecting plate; the contact plate has an arc-shaped structure, and each contact surface between the contact plate and the steel bar is provided with a flexible layer.

[0015] Based on the structure of the adjustable clamp for binding large-diameter steel cages described above, a locking engagement horizontal plate is provided at the end face of the first connecting plate away from the guide rod. The locking engagement horizontal plate is provided with a second threaded hole, and a locking rod is provided in each of the threaded holes. Each of the support plates is provided with a plug hole that engages with the locking rod. The locking rod is provided with an external thread.

[0016] Based on the structure of the adjustable clamp for binding large-diameter steel cages described above, multiple insertion holes are provided along the length of the support plate, the insertion holes are provided on the upper and lower end faces of the support plate, and the connection holes are provided through the left and right end faces of the support plate.

[0017] Based on the structure of the adjustable clamp for binding large-diameter steel cages described above, the connecting hole is an oblong hole.

[0018] Based on the structure of the adjustable clamp for binding large-diameter steel cages described above, a mating plate is provided on the sliding member. The mating plate is made of a flexible material and is located on the end of the sliding member away from the locking rod.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0020] 1. This solution can fix steel cages of different diameters by setting up a sliding component that can move along the length of the support plate. Different sizes of steel cages can be fixed by adjusting a single clamp without changing the clamping component. It also saves adjustment time after disassembly and reduces the overall time required to replace steel cages of different models with large diameters.

[0021] 2. This solution avoids rigid contact between the reinforcing bar and the clamping seat by incorporating a flexible layer on the contact plate, thus preventing damage to the anti-corrosion coating on the reinforcing bar surface. Simultaneously, designing the contact plate as an arc-shaped structure increases the contact area with the reinforcing bar, making the clamping process more stable. Since the clamped reinforcing bar needs to be rotated, the arc-shaped structure of the contact plate can restrict the forward or reverse rotation of the reinforcing bar during rotation.

[0028] Example 1

[0029] like Figure 1 As shown, this utility model provides a technical solution:

[0030] An adjustable clamp for binding large-diameter steel cages includes, but is not limited to, a support plate 1, a sliding member 2, and a clamping member 3. The support plate 1 is provided with a connecting hole 4 that cooperates with an external rotating mechanism. The sliding member 2 is sleeved on both sides of the support plate 1 and can move along the length of the support plate 1. The clamping member 3 is provided on the sliding member 2 and can move closer to or away from the support plate 1.

[0031] Based on the above structure, this solution can fix steel cages of different diameters by setting a sliding member 2 that can move along the length of the support plate 1. The steel cages of different sizes can be fixed by adjusting one clamp, without the need to replace the clamping member. It also saves the adjustment time after disassembly and reduces the time required to replace steel cages of different models with large diameters.

[0032] As an example, the support plate 1 is a rectangular parallelepiped structure, that is, the cross section of the support body and the sliding member 2 is a rectangular structure; the sliding member 2 is provided with a rectangular cavity structure that cooperates with the support body.

[0033] Based on the above structure, by setting the support plate 1 as a cuboid structure and the sliding member 2 as a rectangular cavity structure, the sliding member 2 can be prevented from rotating when the support body is driven to rotate. Since it is a rectangular cavity structure, the sliding member 2 can only move along the length direction of the support plate 1, avoiding relative rotation between the sliding member 2 and the support plate 1, thus ensuring the stability of the support plate 1 and the sliding member 2 in fixing the steel bars.

[0034] As an example, the sliding member 2 may include a sliding sleeve 21 and a support frame 22. The support frame 22 is symmetrically arranged on both sides of the sliding sleeve 21 at the center position along the length direction of the sliding sleeve 21. A first threaded hole 23 that cooperates with the clamping member 3 is provided on the support frame 22.

[0035] The support frame 22 has an overall L-shaped structure, which specifically includes a first connecting plate 221 and a second connecting plate 222. The first connecting plate 221 is arranged perpendicular to the end face of the slider 2, and the second connecting plate 222 is arranged perpendicularly on the end of the first connecting plate 221 away from the slider 2. The second connecting plate 222 is arranged parallel to the slider 2.

[0036] Based on the above structure, by setting support frames 22 on both sides of the sliding sleeve 21, the reinforcing bars can be limited simultaneously on both sides of the sliding sleeve 21. Limiting on both sides can increase the number of reinforcing bars clamped, making it more stable during rotation, and can also achieve stable clamping in both forward and reverse rotation.

[0037] As an example, the clamping component 3 may include a threaded rod 31, a rotating handle 32, a guide rod 33, a rotating bearing 34, and a clamping seat 35; the threaded rod 31 is disposed in the threaded hole of the support frame 22, the guide rod 33 is disposed on the side of the second connecting plate 222 near the support plate 1 and extends a predetermined distance toward the support plate 1, the rotating bearing 34 is disposed on the clamping seat 35, the clamping seat 35 is also provided with a through hole that mates with the guide rod 33, and the rotating handle 32 is disposed on the threaded rod 31.

[0038] Based on the above structure, since the end of the threaded rod 31 is connected to the clamping seat 35 through the rotating bearing 34, and the clamping seat 35 is slidably connected to the guide rod 33, the whole structure presents a screw structure. Rotating the threaded rod 31 will drive the clamping seat 35 to move in a predetermined direction. At the same time, the guide can prevent the clamping seat 35 from rotating, so that it can only move in the direction of approaching or moving away from the support plate 1, and finally achieve the clamping of the steel bar. Since it can be telescopically adjusted, it can quickly adapt to different types of steel bars.

[0039] As an example, the clamping seat 35 may include a support base plate 351 and a contact plate 352; the support base plate 351 is provided with a through hole that mates with the guide rod 33, the rotating bearing 34 is provided on the end face of the support base plate 351 near the second connecting plate 222, and the contact plate 352 is provided on the end face of the support base plate 351 away from the second connecting plate 222.

[0040] The contact plate 352 can be an arc-shaped structure, and a flexible layer 353 is provided on each contact surface between the contact plate 352 and the reinforcing bar.

[0041] Based on the above structure, by providing a flexible layer 353 on the contact plate 352, rigid contact between the reinforcing bar and the clamping seat 35 can be avoided, thus preventing damage to the anti-corrosion layer on the surface of the reinforcing bar. Simultaneously, setting the contact plate 352 to an arc shape increases the contact area with the reinforcing bar, making the clamping process more stable. Since the clamped reinforcing bar needs to be rotated, setting the contact plate 352 to an arc shape allows the two ends of the arc shape to restrict the forward or reverse rotation of the reinforcing bar during rotation.

[0042] As an example, a locking engagement plate 24 is provided on the end face of the first connecting plate 221 away from the guide rod 33. A second threaded hole 25 is provided on the locking engagement plate 24. A locking rod 26 is provided in each threaded hole. An insertion hole 27 that mates with the locking rod 26 is provided on each of the support plates 1. The locking rod 26 is provided with an external thread.

[0043] Based on the above structure, since the support plate 1 will rotate under the action of the driving component, the position may shift during the rotation. Therefore, a locking rod 26 is provided. The locking rod 26 is screwed into the threaded hole of the locking mating plate 24 to achieve stable lifting and lowering. When locking is required, the locking rod 26 is screwed into the insertion hole 27. Locking is achieved by screwing in and out, which can prevent the locking rod 26 from falling off during the rotation.

[0044] As an example, multiple insertion holes 27 are provided along the length of the support plate 1, and the insertion holes 27 are provided on the upper and lower end faces of the support plate 1. The connection holes 4 are provided through the left and right end faces of the support plate 1.

[0045] Based on the above structure, by setting the insertion hole 27 and the connection hole 4 to be on different end faces, the support strength of the support plate 1 can be guaranteed, and damage can be avoided during the rotation support process.

[0046] As an example, the connecting hole 4 can be an oblong hole, which facilitates the cooperation between the support plate 1 and the external rotating components, enabling it to move left and right for easy adjustment.

[0047] As an example, a mating plate 28 is provided on the slider 2. The mating plate 28 is made of a flexible material and is provided on the end of the slider 2 away from the locking lever 26.

[0048] Based on the above structure, the mating plate 28 is used to prevent the reinforcing bars from directly contacting the support plate 1. On the one hand, it can prevent the reinforcing bars in the compressed state from causing damage to the insertion hole 27, and on the other hand, it can also prevent the insertion hole 27 from causing damage to the protective layer of the reinforcing bars.

[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
