Abstract

The invention provides a bending clamp and a bending method for a pre-bent rebar. The pre-bent rebar comprises a straight line section and a pre-bending section connected onto the straight line section, wherein the straight line section and the pre-bending section form a preset angle; the bending clamp comprises a first clamp body and a second clamp body crossed with and hinged to each other; eachof the first clamp body and the second clamp body comprises a clamping end and a holding end opposite to each other; the clamping end of the first clamp body forms a limiting groove for accommodatingthe straight line section; the limiting groove is formed in the side, facing the second clamp body, of the first clamp body; the clamping end of the second clamp body is rotatably connected with a pushing piece; and an accommodating groove for accommodating the pre-bending section is formed in the pushing piece. The bending clamp solves the problem that bending construction is difficult on a rebar bending site.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a bending pliers for pre-bent steel bars and a bending method for pre-bent steel bars. Background technique [0002] At present, in the structural design of our country, there will be some pull hook (hook) steel bar design in the thicker structure. In order to ensure the pulling effect of the drag hook (hook) steel bar, the elbow of this type of steel bar is often required to be bent according to 180°, and there is a straight line section of a certain length after bending. The conventional design of this 180° elbow + straight section is very difficult to construct because of the obstruction of the straight section. In order to be able to hang this kind of hook steel bar, it is often only possible to reduce the 180° bend, but according to the requirements of our country’s regulations, it is necessary to increase the length of the straight line, which also has great ...
