Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a bending device for stirrups of cross-section beams used in building construction. Background Technology

[0002] Building construction refers to the production activities during the implementation phase of an engineering project. It is the process of building various types of buildings, or the process of turning the lines on the design drawings into physical objects at a designated location. It includes foundation construction, main structure construction, roof construction, and decoration construction. The place where construction work is carried out is called the "construction site" or "building site". In building engineering, the reinforcement of beams and columns includes main bars and stirrups. Several main bars are arranged in parallel in a square, while stirrups are squarely tied to all the main bars. After the stirrups are tied to the main bars, the ends of the stirrups need to be bent at 90 degrees to provide better connection and fixation, thereby enhancing the overall strength and stability of the beam and column structure.

[0003] However, existing stirrup bending devices can only produce stirrups of fixed sizes, resulting in a limited range of products and an inability to adjust the stirrup size according to actual usage requirements. Therefore, we provide a stirrup bending device for beam sections used in building construction to solve these problems. Summary of the Invention
