Description

TECHNICAL FIELD

[0001] The utility model relates to the field of building construction, especially a novel steel bar bending device. BACKGROUND

[0002] The bending angle of the two hooks of the single limb hoop in the beam and column composite hoop should not be less than 135 degrees. If the two hooks of the single limb hoop are directly processed into 135 degrees on site, it is time-consuming and laborious to install in the beam and column composite hoop, and the installation efficiency is low. In order to facilitate construction, the current general hoop processing semi-finished product is only bent 135 degrees at one end, and only bent 90 degrees at the other end, and the hoop needs to be further bent on site after installation

[0003] The prior art Chinese utility model patent with application number 201922015018.X discloses a force rod device for bending the single limb hoop in the composite hoop to 135 degrees. The device can bend and install the hoop on site, and the operation is simple. However, the force arm of the device is designed to be short, and a lot of physical strength is needed for bending operation of thick hoop. If the force arm is lengthened, the operation of the device will be limited in some operation areas with limited space. UTILITY MODEL CONTENT

DETAILED DESCRIPTION

[0019] In order to make the technical problems, technical schemes and beneficial effects to be solved by the utility model more clear and obvious, the utility model will be further described in detail in connection with the drawings and embodiments.

[0020] For example Figure 1 And 2As shown in the embodiment, the new reinforcing bar bending device comprises a long straight rod-shaped handle 1, a circular sleeve 2 is arranged at one end of the handle 1, the handle 1 is connected with the circular sleeve 2 through a multi-angle positioning structure 3, so that the position of the handle 1 is conveniently adjusted.

[0021] As shown in the embodiment, Figure 3 The multi-angle positioning structure 3 comprises an ear plate 301 and a positioning rod 302, one end of the ear plate 301 is fixed on the circular sleeve 2, and an arc surface 303 is arranged at the end of the ear plate 301 away from the circular sleeve 2; a plurality of positioning holes 304 are arranged on the arc surface 303 in the circumferential direction; side plates 305 are arranged on both sides of the ear plate 301, the side plates 305 on both sides are fixed on the circular sleeve 2, and an ear shaft 306 is arranged between the ear plates 301 on both sides and is rotationally connected with the ear plates 301; the positioning rod 302 is movably arranged in the handle 1, and one end of the positioning rod 302 is embeddedly matched with the positioning hole 304.

[0022] In the embodiment, the positioning rod 302 is connected in the handle 1 through screw threads, the end of the positioning rod 302 away from the ear plate 301 is exposed to the handle 1, and a knob 307 is arranged on the exposed end of the positioning rod 302.

[0023] In the embodiment, the end of the positioning rod 302 away from the ear plate 301 is exposed to the handle 1, and a knob 307 is arranged on the exposed end of the positioning rod 302.

[0024] In the embodiment, the inner wall of the circular sleeve 2 is provided with an anti-skid knurl 202.

[0025] In the embodiment, the handle 1 is provided with a rubber sleeve 101

[0026] As shown in the embodiment, Figure 4 The operation process of the utility model is as follows:

[0027] The sleeve 4 is rotated, the second opening 401 on the sleeve 4 is corresponded with the first opening 201 on the circular sleeve 2, the hoop hook 8 bent to 90 degrees is put into the sleeve 4 from the first opening 201, then the sleeve 4 is rotated to make the second opening 401 dislocated with the first opening 201, and the handle 1 drives the circular sleeve 2 to bend the hoop hook 8 bent to 90 degrees to 135 degrees.
