Spiral Bar Forming Machine Working Principle

With a microcomputer fully automatic PLC coding numerical control system, users only need to input the spiral bar spacing and the number of meters on the numerical control code display. The spiral bar can be automatically processed and cut. Note: The cutting length error is within 5mm. The machine is widely used in bridge prestress construction. It greatly improves engineering precision and efficiency.

Functions of the Spiral bar

Indirect reinforcement, such as spiral stirrups or welded ring stirrups, can improve the bearing capacity of the cream column. Because sometimes the column needs to withstand a large axial pressure and the cross-sectional size is limited, the increase of the reinforcement and the strength of the concrete can not meet the requirements.

How is it function? The relatively large lateral deformation of the concrete in the core causes the spiral stirrups to generate hoop tension. That is to say, the concrete in the core is subjected to the radial pressure of the spiral stirrups and is under three-way compression.

When the compressive strength is increased, spiral stirrups or welded annular stirrups (collectively referred to as indirect steel bars) can be used to increase the bearing capacity of the column.
