Reinforcing steel bar bending structure, reinforcing steel bar bending device and reinforcing steel bar bending method

Abstract

The invention discloses a reinforcing steel bar bending structure. The reinforcing steel bar bending structure comprises a pushing rod and a supporting frame; the supporting frame comprises two fixingarms; the pushing rod penetrates through the supporting frame and is located between the two fixing arms; sliding wheels are arranged at the ends of the fixing arms; and pressing blocks correspondingto the sliding wheels are further arranged on the fixing arms. Besides, the invention further relates to a reinforcing steel bar bending device utilizing the reinforcing steel bar bending structure and a reinforcing steel bar bending method. The reinforcing steel bar bending structure, the reinforcing steel bar bending device and the reinforcing steel bar bending method have the beneficial effects that through cooperation of the pressing blocks and the sliding wheels, under the action force of the pushing rod, two ends of a reinforcing steel bar are pressed by the pressing blocks, thus the two ends are kept horizontal all the time, and the condition that the strength of a reinforcing steel bar mesh is affected due to the fact that the two ends of the reinforcing steel bar are deformed byforce to pull the adjacent reinforcing steel bar mesh is avoided; and besides, the pressing blocks can slide on the fixing arms, so that reinforcing steel bars in different diameters can be bent by the structure, and the applicability is improved.

Description

Technical field [0001] The invention relates to the field of building construction equipment, in particular to a steel bar bending structure, a steel bar bender and a steel bar bending method. Background technique [0002] When pre-buried pipelines for the production of prefabricated components and water and electricity installations of housing construction projects are reserved for pre-buried, for the installation of electrical light boxes, water supply and drainage pipes and other hydropower pre-embedded parts, it is necessary to locate the pre-buried in strict accordance with the design and construction drawings; However, the actual design drawing does not ensure that all embedded parts are located in the mesh of the steel mesh. Such as figure 1 As shown, the position of the embedded part 20 just falls on the steel bars of the steel mesh 10; in actual construction, it is often encountered that this kind of embedded part conflicts with the position of the steel mesh; at this ti...

Problems solved by technology

There are two existing adjustment methods. One is to cut the steel bar and reinforce at the cut position of the steel bar at the same time. The reinforcement work is mainly to carry out support reinforcement or welding reinforcement within the range of the cut steel bar. The reinforcement process and process are complicated and time-consuming The second is to bend the steel bar by the steel bar bending machine, but due to the influence of the force on the steel bar, the two ends of the steel bar will warp in the opposite direction of the force, which will drive the deformation of the steel bar grid near the steel bar. The deformed steel bar mesh is as follows: figure 2 shown
