Description

Technical Field

[0001] The utility model relates to the technical field of positioning clamps, in particular to a lightweight steel bar clamp for building shear wall construction. Background Art

[0002] In building construction, shear walls are key structural components, and their construction quality is directly related to the building's seismic performance and overall stability. Shear walls are typically made of reinforced concrete. In recent years, lightweight rebar clamps have been widely used in shear wall construction due to their portability, reduced material loss, and ease of maintenance, providing secure support for the rebar.

[0003] However, the traditional design of lightweight rebar clamps generally fixes the angle of the rebar and lacks adjustability, making it difficult for construction workers to adjust according to actual needs in complex construction environments. This design limits the adaptability of the clamps and cannot meet the design requirements of different shear walls. Especially in cases where special rebar configurations are required, it is easy to cause deviations in the position of the rebar, thereby affecting the effect of concrete pouring and the overall strength of the shear wall. On the other hand, the firmness of existing lightweight rebar clamps in fixing rebars also needs to be improved. Many clamps are prone to deformation or loosening under stress and cannot effectively maintain the stable position of the rebar before pouring. In order to solve these technical bottlenecks, it is necessary to innovate in the design and material selection of lightweight rebar clamps, and explore adjustable and more stable structural solutions to meet the needs of modern building construction for efficiency, safety and flexibility. Utility Model Content

[0004] In order to solve the problems of the prior art that the angle of lightweight steel bar clamps cannot be adjusted and the structure is unstable, the utility model proposes a lightweight steel bar clamp for the construction of shear walls of building construction.

[0005] The technical solution of the utility model is as follows:

[0006] A lightweight steel bar fixture for building shear wall construction, comprising a main frame, a rotating column, a fixed rod, a strip frame, a movable rod, and a clamping plate;

[0007] The main frame is in a concave shape;

[0008] The two ends of the main frame are provided with a second cylindrical hole, in which a rotating column is rotatably connected, and a plurality of positioning holes are evenly distributed in a circumference on one end of the two rotating columns away from each other;

[0009] A first cylindrical hole is provided on the main frame and on the side of the second cylindrical hole;

[0010] The fixing rod is concave in shape, one end of which is inserted into the first cylindrical hole; the other end is inserted into the positioning socket on the rotating column;

[0011] The two bar frames are respectively installed at one end of the two rotating columns close to each other; two movable rods are symmetrically installed on one side of the two bar frames close to each other; two clamping plates are respectively installed at one end of the two movable rods on the same bar frame close to each other, so that the first steel bar and the second steel bar are respectively fixed between the two upper clamping plates and the two lower clamping plates.

[0012] Preferably, it further comprises a limiting plate, wherein the limiting plate is connected to one end of the fixing rod passing through the first cylindrical hole;

[0013] Preferably, it further comprises an elastic member, which is sleeved on the fixing rod, with one end of the elastic member in contact with the inner wall of the main frame and the other end in contact with the limiting plate;

[0014] Preferably, the device further comprises a bidirectional threaded rod, the bidirectional threaded rod being rotatably connected to the interior of the bar frame, the bidirectional threaded rod being symmetrically provided with two threaded sliders which are threadedly engaged, and the outer walls of the threaded sliders being respectively slidably engaged with the inner walls of the bar frame, and the sides of the threaded sliders being connected to the movable rod;

[0015] Preferably, it further comprises a turning handle, which is installed at one end of the bar frame away from the main frame and connected to one end of the bidirectional threaded rod;

[0016] Preferably, it further comprises a mounting sleeve, one end of which is mounted on the outer side wall of the clamping plate, and the other end of which is connected to the end of the movable rod away from the bar frame;

[0017] Preferably, it further comprises screws, wherein the screws fix the mounting sleeve and the movable rod;

[0018] Preferably, it further comprises an elastic pad, which is installed on the inner surface of the clamping plate.

[0019] Compared with the existing technology, the utility model solves the problem of the existing lightweight steel bar clamps having unadjustable angles and unstable structures, and has the following beneficial effects:

[0020] 1. Improved Fixing Efficiency: Traditional rebar fixing methods often require significant time to connect and secure the rebar, especially when handling interlaced rebar. This significantly increases the difficulty and time required. However, using this lightweight rebar fixture for shear wall construction allows workers to quickly place two interlaced rebars into the clamping plate and adjust the clamping angle using the rotating column, rapidly securing the rebar. This design significantly improves construction efficiency, reduces labor costs, and reduces construction time.

[0021] 2. Adjustable Clamping Angle: In building construction, different construction environments and design requirements often require different rebar fixing angles. This lightweight rebar clamp for shear wall construction allows for flexible adjustment of the clamping angle by adjusting the rotating column to accommodate various construction needs. This feature allows construction workers to quickly adjust the clamping angle in complex construction environments without having to change fixing tools, improving construction flexibility and adaptability.

[0022] 3. Enhanced Fixing Stability: The lightweight steel bar fixtures used in this shear wall construction utilize fixed rods to secure the rotating column, ensuring the stable fixing of the steel bars during construction. This design effectively prevents steel bar displacement caused by vibration or other external factors during construction, ensuring construction quality while also improving safety. The stable clamping plate design reduces safety hazards caused by steel bar falling. Furthermore, the simple operation process reduces the possibility of operator error and enhances the safety of the entire construction process. BRIEF DESCRIPTION OF THE DRAWINGS
