Description

Technical Field

[0001] The utility model relates to the technical field of steel bar processing, in particular to a portable stirrup bending tool. Background Art

[0002] Stirrups are important load-bearing steel bars in concrete structures. They are used to meet the shear strength of inclined sections and connect the main load-bearing bars and the steel bars of the mixed reinforcement skeleton in the compression zone. Their main function is to restrain the lateral deformation of concrete, thereby reinforcing and enhancing the bearing capacity of concrete columns, beams and other components. They are widely used in structural columns and beams of construction projects.

[0003] Stirrups are usually processed centrally using stirrup bending machines. The principle of the stirrup bending machine is to bend the steel bar material through a mechanical transmission and control system to meet the needs of the project. The stirrup bending machine has the characteristics of easy operation, high processing efficiency, and low manual labor intensity. The stirrup bending machine is a small-scale electric construction equipment with a large size and heavy weight. There are certain safety hazards during operation. It is mostly placed indoors for use. When used outdoors, the equipment must be protected from rain and snow. It is widely used for the processing of large-diameter stirrups and stirrups with large demands. For buildings with small beam-column structures and small stirrup demands, such as pavilions, corridors, power distribution rooms, guard houses, pump stations, and some small buildings with irregular beams and columns, the use of stirrup bending machines to process stirrups has the problem of wasting materials and is very uneconomical.

[0004] Therefore, how to design a convenient stirrup processing tool to replace the traditional stirrup bending machine with a portable tool for working conditions where small stirrups are required in small structures, and ensure that the bending angle standards of the stirrups are uniform, has become a technical problem that needs to be solved urgently by people in this field.
