Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of building construction, and particularly relates to a simple wrench for the hook of a tie bar. Background Art
[0002] In the construction of the main structure of traditional projects, when steel bar workers bend single-leg stirrups, stirrups and tie bars, they use steel sleeves for bending to ensure that the bending angles of single-leg stirrups, stirrups and tie bars meet the design requirements. This method is inefficient, laborious for bending, and difficult for workers to operate. During on-site construction, problems often occur that the acceptance fails due to insufficient bending angles and insufficient straight section lengths of the wrench hooks. And during the actual construction process, stirrups are processed by a steel bar bender into 90° bends at both ends. According to the specification requirements, 135° wrench hooks are required at both ends of the stirrups. In order to facilitate bending with a steel sleeve, 30 - 50 mm is usually added to both ends of the stirrups, resulting in material waste. Content of the Utility Model
[0003] The purpose of the utility model is to overcome the defects existing in the prior art and provide a simple wrench for the hook of a tie bar.
[0004] The utility model provides a simple wrench for the hook of a tie bar, which includes a bearing plate. A stirrup clamping groove is formed at the top of the bearing plate, and a wrench rod is arranged at the bottom of the bearing plate;
[0005] A wrench hook is arranged on the bearing plate, and the wrench hook extends out of the top of the bearing plate to form a clamping part.
[0006] Further, two groups of wrench hooks are provided, and the two groups of wrench hooks are symmetrically arranged along the stirrup clamping groove.
[0007] Further, the bending angle of the wrench hook is greater than 90°.
[0008] Further, the wrench hook is welded to the back of the bearing plate.
[0009] Further, a handle is arranged at one end of the wrench rod away from the bearing plate.
[0010] Further, the wrench rod includes a fixed section, a connecting section and a handle section, and the fixed section, the connecting section and the handle section are connected in sequence;
[0011] One end of the fixed section is connected to the bottom of the bearing plate. Threaded sections are arranged at the ends of the fixed section and the connecting section away from the bearing plate. Threaded holes are formed at the ends of the connecting section and the handle section close to the bearing plate, and the threaded holes are adapted to the threaded sections.
[0012] Compared with the prior art, the beneficial effects of the utility model are as follows: When bending the stirrup, the two wrench hooks of the utility model can be hung on the main beam steel bars, and the bent end of the stirrup is clamped with the stirrup card slot. By using the lever principle, the bent end of the stirrup can be quickly bent, which can speed up the construction progress while saving the original steel materials, avoiding material waste, and reducing costs and increasing efficiency for the construction unit. The utility model can be used for bending single-leg stirrups of frame columns, bending stirrups of frame beams, and bending tie bars of shear walls, with strong applicability.

[0020] In order to make the purpose, technical solutions, design methods and advantages of the utility model clearer, the following further details the utility model through specific embodiments in conjunction with the drawings. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model.
[0021] Such as Figure 1As shown in the figure, the utility model provides a simple wrench for the hook of the tie bar, which includes a bearing plate 1. A stirrup clamping groove 3 is provided at the center of the top of the bearing plate 1, and a wrench rod 4 is arranged at the bottom of the bearing plate 1. A wrench hook 2 is arranged on the bearing plate 1. There are two groups of the wrench hooks 2, and the two groups of the wrench hooks 2 are symmetrically arranged along the stirrup clamping groove 3. The wrench hook 2 is welded to the back of the bearing plate 1, and the bending angle of the wrench hook 2 is greater than 90°. In this embodiment, the bearing plate 1 is a U-shaped steel plate structure with a thickness of not less than 3 mm. The stirrup clamping groove 3 is arranged in the middle of the U-shaped steel plate, and the stirrup clamping groove 3 is in the form of a "V" shape with a large outer opening and a small inner opening, which is convenient for the stirrup to be clamped with the stirrup clamping groove 3. The return bending angle of the wrench hook 2 is 180°. The two sides at the rear end of the U-shaped steel plate are connected to the wrench hook 2. The wrench hook 2 is made of a steel bar raw material with a diameter of 8 mm. The steel bar is symmetrically processed into a U shape, and the tops of the two sides of the steel bar are bent back to 180 degrees to form a hook shape. The wrench hook 2 is welded to the rear side of the U-shaped steel plate and welded to the wrench rod 4, so that the U-shaped steel plate, the wrench hook 2 and the wrench rod 4 form an integral body. In order to improve the comfort of the user, a handle 5 is arranged at one end of the wrench rod 4 far from the bearing plate 1. In this embodiment, the handle 5 is a rubber sleeve or a sponge sleeve, which is tightly sleeved at the end of the wrench rod 4.
[0022] For different working conditions, the required lengths of the wrench rods 4 may be different. For example, Figure 2 As shown in the figure, in this embodiment, the wrench rod 4 includes a fixed section 4.1, a connecting section 4.3 and a handle section 4.4. The fixed section 4.1, the connecting section 4.3 and the handle section 4.4 are connected in sequence. One end of the fixed section 4.1 is connected to the bottom of the bearing plate 1. Threaded sections 4.2 are arranged at the ends of the fixed section 4.1 and the connecting section 4.3 far from the bearing plate 1. Threaded holes are provided at the ends of the connecting section 4.3 and the handle section 4.4 close to the bearing plate 1, and the threaded holes are adapted to the threaded sections 4.2.
[0023] For example, Figures 3 - 5 As shown in the figure, when bending the stirrup 7, first fix the stirrup 7 to the main beam steel bar 6, then fix the bent section of the stirrup 7 to be bent in the stirrup clamping groove 3, and the wrench hook 2 is hooked on the adjacent main beam steel bar 6 of the stirrup 7. The two wrench hooks 2 are respectively located on both sides of the stirrup 6. Apply a downward force to the end of the wrench, and the 90° bent section of the stirrup 6 can be bent to the angle that meets the design requirements. It should be noted that during the construction process of a building, multiple tie bars need to be set on the same frame beam or shear wall. Therefore, it is impossible to ensure that the bending angles of each tie bar after bending are all 135°. However, the two ends of the tie bar bent by using this wrench are bent towards the center of the frame beam, which can play the role of a tie bar. The bending angle is judged by the construction workers according to experience, and the error is within the allowable range.
[0024] The embodiments of the present utility model have been described above. The above description is exemplary and not exhaustive, and is also not limited to the disclosed embodiments. Many modifications and variations are obvious to those of ordinary skill in the art in the technical field without departing from the scope and spirit of the described embodiments. The selection of the terms used herein is intended to best explain the principles of the embodiments, practical applications, or improvements to the technology in the market, or to enable other ordinary technical personnel in the technical field to understand the embodiments disclosed herein.
