In the steel bar construction of construction sites, stirrups, as the “muscles and bones” of concrete structures, do not come in a single shape. Instead, they are designed in various forms according to component types, force requirements and construction scenarios. Their core functions are to fix longitudinal steel bars, resist shear force and torque, and constrain core concrete. Different shapes of stirrups accurately adapt to different construction needs, laying a solid foundation for the safety of building structures.
Rectangular stirrups are the most commonly used type in construction. They are made of four straight steel bars bound or welded into a closed rectangle, featuring simple structure and convenient construction. They are widely applied to rectangular cross-section components such as beams and columns, especially suitable for areas with large shear force such as beam ends and column feet. They can effectively fix longitudinal steel bars and prevent their force deviation.
Spiral stirrups are arranged in a continuous spiral shape around the longitudinal axis of components. They are mostly used for components requiring high binding force such as circular or square columns and piles. Compared with rectangular stirrups, they constrain concrete more evenly, which can significantly improve the ductility and seismic performance of components, but the construction complexity is relatively higher.
Composite stirrups are composed of multiple rectangular stirrups, such as cross-shaped, double-legged and four-legged stirrups. They are suitable for large cross-section components or areas with high shear resistance requirements, such as wide-flat beams and core tube columns. By increasing the number of stirrup legs, the binding range of longitudinal steel bars can be expanded, the stability of the steel frame can be enhanced, and the lateral deformation of concrete can be better restricted.
In addition, there are special-shaped stirrups such as octagonal and U-shaped ones, which are suitable for special scenarios such as circular cross-section components and shear wall hidden beams. The selection of different shapes of stirrups not only follows the building structure design specifications, but also takes construction convenience into account, ensuring that each component can bear the corresponding load, providing a solid guarantee for the overall safety of the building, and reflecting the professionalism and rigor of building construction.
Our full-automatic stirrup beding machine series is specially designed to meet the stirrup needs of construction scenarios. It supports single-line processing of steel bars with a diameter of 5-13mm and double-line processing of steel bars with a diameter of 5-10mm. Equipped with a numerical control panel, it can pre-input 100 types of stirrup shapes, which can be retrieved and used directly during processing, greatly saving time and labor. Moreover, it can freely edit stirrup graphics according to drawing requirements, fully adapting to diverse construction needs. The whole machine boasts numerous advantages, including energy conservation and consumption reduction, time and labor saving, safety and efficiency, and reducing workers’ labor intensity. It is the ideal choice for your construction site. Welcome to consult and purchase.
