Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steel bar binding in building construction engineering, and particularly relates to a device for bending the hook of a stirrup on site. Background Art
[0002] In building construction, stirrups are usually arranged in the horizontal and vertical directions of shear walls as construction measures, and the hook designs on both sides of the stirrup are 135°. If the hooks on both sides of the stirrup are processed into 135° in advance, they cannot be bound and fixed on site. During actual construction, one end of the stirrup is processed into a 90° hook and the other end is processed into a 135° hook. During installation, the 135° hook is first bound, and then the 90° hook end is bent, and then bound and fixed after bending. This method has the disadvantages of poor forming effect, low work efficiency, and high labor intensity. Based on this, it is necessary to provide a stirrup hook bending device with strong operability and high work efficiency. Content of the Utility Model
[0003] The purpose of the utility model is to provide a device for bending the hook of a stirrup on site to improve the disadvantages of low efficiency and high labor intensity during the installation of existing stirrups.
[0004] The technical solution adopted by the utility model is: a device for bending the hook of a stirrup on site, including a bending stop bar. Positioning members are arranged at both ends of the circumferential side of the bending stop bar. The positioning members are provided with positioning grooves for accommodating the main steel bars. A space is left between the two positioning members to accommodate the stirrup. Connecting rods are arranged at both ends of the circumferential side of the bending stop bar far from the positioning members, and the distal ends of the connecting rods are connected with operating handles.
[0005] Further, the connecting rod is Y-shaped, and its bifurcated end is connected to the bending stop bar.
[0006] Further, the bending stop bar, the connecting rod, and the operating handle are made by processing round steel, and the positioning member is cut from a steel pipe.
[0007] Further, the radius of the positioning member is 15 mm, and the arc length is 47 mm.
[0008] Further, the diameter of the bending stop bar is 12 mm.
[0009] The utility model has the following beneficial effects:
[0010] It can use local materials and is convenient for processing and manufacturing. During on-site operation, the positioning groove of the positioning member is stuck on the longitudinal or transverse main steel bar, the stirrup is placed in the middle of the positioning member, and the operating handle is rotated in the direction of the hook bending. The bending stop bar drives the stirrup to bend. After the hook angle reaches the design requirement, the stirrup can be bound and fixed to the main steel bar. This device is simple to operate, greatly improves work efficiency, and reduces labor intensity. Description of the Drawings

[0014] In order to better understand the purpose, structure and function of the present utility model, the following further describes in detail a device for bending tie bar hooks on site according to the present utility model with reference to the accompanying drawings.
[0015] As Figure 1 and Figure 2 shown, a device for bending tie bar hooks on site includes a bending stop bar 2. Positioning members 1 are arranged at both ends of the circumferential side of the bending stop bar 2. The positioning member 1 is provided with a positioning card slot for accommodating the main reinforcement 5. A space is left between the two positioning members 1 to accommodate the tie bar 6. Connecting rods 3 are arranged at both ends of the circumferential side of the bending stop bar 2 away from the positioning members 1. The distal ends of the connecting rods 3 are connected with an operating handle 4.
[0016] In this embodiment, the bending stop bar 2, the connecting rods 3 and the operating handle 4 are processed and made from round steel. The diameter of the bending stop bar 2 is preferably 12 mm. The positioning member 1 is cut from a steel pipe, with a radius preferably 15 mm and an arc length preferably 47 mm. The bending stop bar 2 and the positioning member 1 are welded and connected. The operating handle 4 is made from round steel with a diameter of 12 mm, and the length of the operating handle 4 is preferably 100 mm.
[0017] The connecting rod is welded into a Y shape from round steel with a diameter of 12 mm. Its bifurcated end is connected with the bending stop bar 2 to form a triangle, and the height of the triangle is preferably greater than 100 mm. According to actual usage needs on site, the triangular form can also be changed into a rectangular form.
[0018] The construction process of using this device is as follows: One end of the tie bar 6 to be tied is processed into 135°, and one end is not processed (straight section). After the on-site steel bar skeleton is tied, at the designed position, the 135° hook end of the tie bar 6 is tied and fixed. The positioning card slot of the positioning member 1 is stuck on the main reinforcement 5. The straight section of the tie bar 6 is located in the middle of the two positioning card slots. The operating handle 4 is rotated in the direction of the hook bending, and the straight section of the tie bar 6 rotates with the bending stop bar 2 to complete the bending of the tie bar hook.
