Description

Technical Field

[0001] This utility model relates to the field of steel bar limiting structure technology, and more specifically, to a multi-directional reinforced wall steel bar limiting device. Background Technology

[0002] Reinforcing steel bars are the core load-bearing framework of a concrete shear wall. As the wall's internal supporting structure, they play a crucial role in supporting the wall from within and stabilizing its structure. The reinforcing steel bars in a concrete shear wall mainly consist of transverse reinforcing bars extending horizontally and longitudinal reinforcing bars extending vertically. During the installation of the internal reinforcing steel bars, these bars are vertically and alternately tied to form a planar mesh framework that bears the main stresses of the wall. This planar mesh framework, as the core internal supporting structure of the concrete shear wall, ensures the structural stability and load-bearing capacity of the wall. Currently, on construction sites, the fixing of the joints between these transverse and longitudinal reinforcing bars mostly relies on manual tying by construction workers to limit the displacement of the transverse and longitudinal reinforcing bars. However, this traditional fixing and limiting method has two shortcomings: On the one hand, the tightness and reliability of the binding largely depend on the individual experience and skill level of the construction workers, making it difficult to uniformly control the quality of the binding. This can easily lead to missed bindings, loose bindings, or excessively tight bindings that damage the binding wires, thus posing a potential safety hazard to the wall structure. On the other hand, when using binding wire, construction workers can only apply a general, non-directional binding force to the intersection of horizontal and vertical reinforcing bars through winding and twisting operations. They cannot simultaneously provide effective and reliable constraint forces to the intersecting reinforcing bars in both the horizontal and vertical directions. In other words, the wire binding method cannot simultaneously provide multi-directional constraint to the intersecting reinforcing bars at their intersections. Utility Model Content

[0003] The purpose of this utility model is to provide a multi-directional reinforcement wall steel bar limiting device to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution.

[0005] This utility model provides a multi-directional reinforced wall reinforcement limiting device, comprising two reinforcing bars arranged in a cross shape, the two reinforcing bars having a common first side and a second side, and further comprising: A cross-shaped steel bar sleeve is attached to the outer surface of the cross-shaped intersection of the two steel bars from the first side, and each end of the cross-shaped steel bar sleeve is provided with two insertion holes; Four clips, each clip having two ends, clamping the outer surface of the two reinforcing bars from the second side along the radial direction of the reinforcing bars, and the two ends respectively passing through the two insertion holes; Four fixing sleeves, each with a slot inside, the two ends of the clip pass through the insertion hole and are inserted into the slot, the fixing sleeve is attached to the outer surface of the cross-shaped steel bar sleeve from the first side of the two steel bars.

[0006] In some embodiments of this application, the cross-shaped reinforcing bar sleeve includes a longitudinal reinforcing bar sleeve and a transverse reinforcing bar sleeve. The longitudinal reinforcing bar sleeve has a transverse reinforcing bar groove for fixing the transverse reinforcing bar sleeve. In some embodiments of this application... In some embodiments of this application, the clip is C-shaped, U-shaped, or V-shaped, and two symmetrical inserts are formed at both ends of the clip; the fixing sleeve has two slots, and each slot is adapted to the shape of each insert.

[0007] In some embodiments of this application, the insert end of the clip is formed with a bevel, and each insert end of the clip is also provided with a slot; the slot of the fixing sleeve forms a bevel adapted to the insert of the clip and a card block adapted to the slot.

[0008] In some embodiments of this application, the clamp includes a longitudinal rebar clamp and a transverse rebar clamp; wherein, the longitudinal rebar clamp is provided with a longitudinal rebar push block for pressing the rebar extending longitudinally, and the transverse rebar clamp is provided with a transverse rebar slot for clamping the rebar extending transversely.

[0009] In some embodiments of this application, an arc-shaped groove is provided between the two slots of the fixing sleeve, which corresponds to the position of the longitudinal reinforcing bar push block or the transverse reinforcing bar slot when the clip is inserted into the fixing sleeve.

[0010] In some embodiments of this application, a shearing groove is provided at the top and bottom of the fixing sleeve, the shearing groove is symmetrically arranged with respect to the central axis of the fixing sleeve, and the shearing groove is perpendicular to the arc-shaped groove.

[0011] In some embodiments of this application, the cross-shaped reinforcing bar is fitted with at least four adsorption magnets; wherein, two of the adsorption magnets are disposed on the longitudinal reinforcing bar sleeve for adsorbing the reinforcing bar extending longitudinally, and two of the adsorption magnets are disposed on the transverse reinforcing bar sleeve for adsorbing the reinforcing bar extending transversely; the adsorption magnets are symmetrically distributed relative to the intersection of the reinforcing bars.

[0012] In some embodiments of this application, the clip and / or the retaining sleeve are made of an elastic material.

[0013] As can be seen from the above technical solution, the embodiments of this utility model have at least the following advantages and positive effects: This utility model discloses a wall reinforcement limiting device for multiple reinforcements. First, a cross-shaped steel bar sleeve is used to press against the outer surface of the cross-shaped intersection of two steel bars from the first side. Then, a clamp is used to clamp the outer surface of the steel bars from the second side along the radial direction of the steel bars. At the same time, the two ends of the clamp pass through two insertion holes at each end of the cross-shaped steel bar sleeve. Thus, in the longitudinal and transverse extension directions of the cross-shaped steel bars, each end of the cross-shaped steel bar sleeve cooperates with one of the clamps, radially clamping the outer surface of the steel bars, thereby achieving multi-directional reinforcement of the cross-shaped steel bars.

[0014] The two ends of the clip pass through the two holes on the cross-shaped rebar sleeve and are inserted into the slot of the fixing sleeve. At the same time, the fixing sleeve is pressed against the outer surface of the cross-shaped rebar sleeve from the first side of the two rebars. This not only effectively prevents the clip from coming out of the holes, but also makes the cross-shaped rebar sleeve fit more tightly with the rebar, further enhancing the fixing effect of the cross-shaped rebar sleeve and the clip on the rebar.

[0015] The wall reinforcement limiting device of this utility model can radially clamp the reinforcement through the cooperation of each end of the cross-shaped reinforcement sleeve and the clamp after installation, effectively strengthening the cross-shaped intersecting reinforcement, thereby improving the overall stability and load-bearing reliability of the wall reinforcement skeleton.

[0030] Please see Figures 1 to 10 This utility model provides a multi-directional reinforced wall reinforcement 1 limiting device, which mainly includes two steel bars 1 arranged in a cross shape. The two steel bars 1 have a common first side and a second side. It also includes: a cross-shaped steel bar sleeve 2, which is attached to the outer surface of the cross-shaped intersection of the two steel bars 1 from the first side, and each end 31 of the cross-shaped steel bar sleeve 2 is provided with two insertion holes 21; four clips 3, each clip 3 including two ends 31, which clamp the outer surface of the steel bar 1 from the second side of the two steel bars 1 along the radial direction of the steel bar 1, and the two ends 31 respectively pass through the two insertion holes 21; and four fixing sleeves 4, each fixing sleeve is provided with a slot 41 inside. The two ends 31 of the clips 3 pass through the insertion holes 21 and are inserted into the slots 41. The fixing sleeves 4 are attached to the outer surface of the cross-shaped steel bar sleeve 2 from the first side of the two steel bars 1.

[0031] This utility model discloses a wall reinforcement limiting device with multiple reinforcements. First, a cross-shaped steel bar sleeve 2 is used to press against the outer surface of the cross-shaped intersection of two steel bars 1 from the first side. Then, a clamp 3 is used to clamp the outer surface of the steel bars 1 from the second side along the radial direction of the steel bars 1. At the same time, the two ends 31 of the clamp 3 pass through the two insertion holes 21 at each end of the cross-shaped steel bar sleeve 2. Thus, in the longitudinal and transverse extension directions of the cross-shaped steel bars 1, each end of the cross-shaped steel bar sleeve 2 cooperates with a clamp 3 to radially clamp the outer surface of the steel bars 1, thereby realizing multi-directional reinforcement of the cross-shaped steel bars 1.

[0032] The end 31 of the clip 3 passes through the insertion hole 21 on the cross-shaped rebar sleeve 2 and is inserted into the slot 41 of the fixing sleeve 4. At the same time, the fixing sleeve 4 is pressed against the outer surface of the cross-shaped rebar sleeve 2 from the first side of the two rebars 1. This not only effectively prevents the clip 3 from coming out of the insertion hole 21, but also makes the cross-shaped rebar sleeve 2 and the rebar 1 fit more tightly, further enhancing the fixing effect of the cross-shaped rebar sleeve 2 and the clip 3 on the rebar 1.

[0033] The wall reinforcement limiting device of this utility model can radially clamp the reinforcement 1 by cooperating with each end of the cross-shaped reinforcement sleeve 2 and the clamp 3 after installation, effectively strengthening the cross-shaped intersecting reinforcement 1, thereby improving the overall stability and load-bearing reliability of the wall reinforcement 1 skeleton.

[0034] In a preferred embodiment, the cross-shaped steel bar sleeve 2 includes a longitudinal steel bar sleeve 22 and a transverse steel bar sleeve 23. The longitudinal steel bar sleeve 22 is provided with a transverse steel bar groove 221 for fixing the transverse steel bar sleeve 23.

[0035] Through modular design, the cross-shaped rebar sleeve 2 is disassembled into a longitudinal rebar sleeve 22 and a transverse rebar sleeve 23. The transverse rebar sleeve 23 is positioned and assembled through the transverse rebar groove 221 on the longitudinal rebar sleeve 22. The modular design not only reduces the manufacturing difficulty of the cross-shaped rebar sleeve 2, but also reduces the transportation space required for the cross-shaped rebar sleeve 2. During installation, the construction personnel can insert the transverse rebar sleeve 23 into the transverse rebar groove 221 to pre-assemble the cross-shaped rebar sleeve 2. Then, the assembled cross-shaped rebar sleeve 2 is axially inserted from one end of the rebar 1 until the intersection of the rebar 1, so that the longitudinal rebar sleeve 22 is close to the rebar 1 from the first side of the two rebars 1, and at the same time, the transverse rebar sleeve 23 is also close to the rebar 1 from the first side of the two rebars 1.

[0036] In a preferred embodiment, the clip 3 is C-shaped, U-shaped, or V-shaped, and the two ends 31 of the clip 3 form two symmetrical inserts 311; the fixing sleeve 4 has two slots 41 and each slot 41 is adapted to the shape of each insert 311.

[0037] By forming symmetrical inserts 311 at the end 31 of the clip 3, the end 31 of the clip 3 is subjected to uniform force when the inserts 311 are engaged with the slot 41, thus avoiding the clip 3 from becoming skewed or loose due to uneven force, which would affect the connection stability between the clip 3 and the steel bar 1 and the fixing sleeve 4.

[0038] During construction, the workers clamp the clip 3 from the second side of the two reinforcing bars 1 along the radial direction of the reinforcing bars 1 onto the outer surface of the reinforcing bars 1. The insert 311 at the end 31 of the clip 3 passes through the insertion hole 21 on the cross-shaped reinforcing bar sleeve 2 and then into the slot 41 of the fixing sleeve 4. The slot 41 is adapted to the shape of the insert 311 and locks the insert 311 from the first side of the two reinforcing bars 1 to prevent it from coming out. By cooperating with the slot 41 of the slot 41 of the C-shaped, U-shaped or V-shaped clip 3, the reinforcing bars 1 and the cross-shaped reinforcing bar sleeve 2 are firmly fixed, effectively preventing relative movement or separation between the reinforcing bars 1 and the cross-shaped reinforcing bar sleeve 2.

[0039] Preferably, the clip 3 is U-shaped. The two arms of the U-shaped structure are parallel and symmetrical, which makes the symmetry of the insert 311 better and ensures that the insert 311 is subjected to uniform force when it is inserted into the slot 41 of the fixing sleeve 4. It also improves the structural rigidity of the clip 3, making the clip 3 less likely to deform or break when subjected to external impact. In addition, the U-shaped structure also allows the arc-shaped bottom of the clip 3 to better fit the outer surface of the reinforcing bar 1.

[0040] In a preferred embodiment, the end of the insert 311 of the clip 3 is formed with a bevel 3111, and each end of the insert 311 of the clip 3 is also provided with a slot 3112; the slot 41 of the fixing sleeve 4 is formed with a bevel 411 that is adapted to the insert 311 of the clip 3 and a card block 412 that is adapted to the slot 3112.

[0041] By forming a bevel 3111 at the end of the insert 311, and forming a bevel 411 in the slot 41 of the fixing sleeve 4 that matches the bevel 3111, the bevel 3111 and the bevel 411 act as guides when the construction worker inserts the insert, allowing the insert 311 to enter the slot 41 more smoothly. This makes it easier for the construction worker to put the fixing sleeve 4 on the outside of the insert 311, improving the convenience of assembly. By setting a slot 3112 at the end of the insert 311, and forming a locking block 412 in the slot 41 of the fixing sleeve 4 that matches the slot 3112, the slot 3112 and the locking block 412 engage after the insert 311 is inserted into the slot 41 and assembled in place. This engagement structure can firmly lock the insert 311 and effectively prevent the insert 311 from coming out of the slot 41.

[0042] In a preferred embodiment, the clamp 3 includes a longitudinal rebar clamp 32 and a transverse rebar clamp 33; wherein, the longitudinal rebar clamp 32 is provided with a longitudinal rebar push block 321 for pressing the longitudinally extending rebar 1, and the transverse rebar clamp 33 is provided with a transverse rebar slot 331 for clamping the transversely extending rebar 1. Specifically, the top end of the longitudinal rebar push block 321 is arc-shaped, and the arc shape is adapted to the outer surface shape of the rebar 1; the transverse rebar slot 331 is arc-shaped, and the arc shape is adapted to the outer surface shape of the rebar 1.

[0043] Therefore, when the construction workers install the clamp 3, the longitudinal reinforcing bar push block 321 of the longitudinal reinforcing bar clamp 32 approaches the outer surface of the reinforcing bar 1 from the second side of the two reinforcing bars 1, and the arc-shaped top of the longitudinal reinforcing bar push block 321 fits and presses against the outer surface of the reinforcing bar 1; the transverse reinforcing bar slot 331 of the transverse reinforcing bar clamp 33 approaches the outer surface of the reinforcing bar 1 from the second side of the two reinforcing bars 1, and the arc-shaped transverse reinforcing bar slot 331 fits and clamps against the outer surface of the reinforcing bar 1.

[0044] In a preferred embodiment, an arc-shaped groove 42 is provided between the two slots 41 of the fixing sleeve 4, which corresponds to the position of the longitudinal reinforcing bar push block 321 or the transverse reinforcing bar slot 331 when the clip 3 is inserted into the fixing sleeve 4. Specifically, the arc-shaped groove 42 is adapted to the outer contour of the cross-shaped reinforcing bar sleeve 2.

[0045] By setting an arc-shaped groove 42 that matches the outer contour of the cross-shaped rebar sleeve 2, and with the arc-shaped groove 42 corresponding to the position of the longitudinal rebar push block 321 or the transverse rebar slot 331, when the fixing sleeve 4 is fitted onto the end 31 of the clamp 3, the arc-shaped groove 42 tightly adheres to and presses against the outer surface of the cross-shaped rebar sleeve 2 from the first side of the two rebars 1. Thus, the fixing sleeve 4 not only prevents the clamp 3 from dislodging from the insertion hole 21, but also firmly fixes the cross-shaped rebar sleeve 2 through the arc-shaped groove 42, eliminating the potential gap between the cross-shaped rebar sleeve 2 and the rebar 1, making the fit between the cross-shaped rebar sleeve 2 and the rebar 1 tighter, thereby further enhancing the fixing effect of the cross-shaped rebar sleeve 2 and the clamp 3 on the rebar 1.

[0046] In a preferred embodiment, the top and bottom of the fixing sleeve 4 are respectively provided with a shearing groove 43. The shearing groove 43 is symmetrically arranged with respect to the central axis of the fixing sleeve 4, and the shearing groove 43 is perpendicular to the arc-shaped groove 42. By providing the shearing groove 43, when it is necessary to disassemble the longitudinal rebar clamp 32 or the transverse rebar clamp 33, the hydraulic shear is aligned with the position of the shearing groove 43 for cutting. After the cutting is completed, the fixing sleeve 4 breaks, and the slot 41 loses its ability to constrain the end 31 of the clamp 3 due to the breakage of the fixing sleeve 4. At this time, the insert 311 of the end 31 of the clamp 3 is no longer restricted by the locking of the fixing sleeve 4 and can be directly dislodged from the slot 41 of the failed fixing sleeve 4.

[0047] In a preferred embodiment, the cross-shaped rebar sleeve 2 is provided with at least four adsorption magnets 5; two of the adsorption magnets 5 are disposed on the longitudinal rebar sleeve 22 for adsorbing the longitudinally extending rebar 1, and two of the adsorption magnets 5 are disposed on the transverse rebar sleeve 23 for adsorbing the transversely extending rebar 1; the adsorption magnets 5 are symmetrically distributed relative to the intersections of the rebar 1. By providing the adsorption magnets 5, when the cross-shaped rebar sleeve 2 is fitted onto the rebar 1, the magnetic force generated by the adsorption magnets 5 adsorbs the rebar 1, pre-fixing the position of the rebar 1 and effectively preventing the rebar 1 from slipping, thereby facilitating the subsequent installation of the clamp 3. It is understood that the mass of the adsorption magnets 5 can be 4, 8, 16, etc.; in this embodiment, the adsorption magnets 5 are 4.

[0048] In a preferred embodiment, the clip 3 and / or the retaining sleeve 4 are made of an elastic material. The elastic material of the clip 3 and / or retaining sleeve 4 allows for moderate elastic deformation during insertion, thus smoothly guiding the insert 311 at the end 31 of the clip 3 into the slot 41 of the retaining sleeve 4. After the insert 311 is inserted into the slot 41, the slot 3112 on the insert 311 and the locking block 412 inside the slot 41 engage tightly to form a lock. The elastic material includes, but is not limited to, plastic, spring steel, etc.

[0049] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
