China automatic cnc stirrup bender / stirrup rebar bending machine stirrup making machine

used stirrup making machine with automatic stirrup rebar bending type, tnt ring machine is necessary construction equipment.stirrup in construction is must and helpful.why need use stirrups in concrete?

First The role of stirrups

reinforcement concrete beams and columns are indispensable for stress and erection reinforcement. They are necessary conditions to ensure that the concrete beams and columns are stable and firm under tension and compression. However, when the beam is under force, have difference strength. One is the upper part compressed,second the lower part pulled,  and third shear stress is generated on the oblique section.

stirrups

Stirrups are also indispensable in not only beams but also columns. Although under normal circumstances the column does not need to bear a large lateral load, once an earthquake occurs, the role of stirrups will not be replaced!Second, the problems that should be paid attention to during the use of stirrups.

  1. How to determine the number of stirrups?

Because the oblique section shear stress is the largest at the fulcrum, not only the oblique reinforcement must be installed, but the number of stirrups will also increase, which is twice the number of other parts of the beam. Generally, the spacing of stirrups at the mid-span of the beam is 200mm, and the spacing of the stirrups at the beam-column node is 100mm.

What is the length of the stirrup encryption zone? What is the diameter?The length of the stirrup densification zone is 1.5 times the beam height or column section size and not less than 500mm. The diameter is not less than 1/4 of the diameter of the beams and columns to which it is fixed, and not less than 6mm.steel stirrup bender

 

As we all know, there are two types of steel rebar stirrup bender. One is S type, this is type used anti-twist system, also called advanced feeding system. It is feature as s shape rebar feeding. Another is line type.it is traditional type. It is feature with horizontal straightening and vertical straightening system.let see difference between anti-twist rebar stirrup bender and common stirrup rebar bending machine

rebar cage making machine

this is the bored pile reinforcement cage welding machine, that is The working principle of “rebar cage forming machine”.It has feature as following:

◆ Fast processing speed: usually, the material preparation and cnc cage welding parts are divided into two shifts. 10 people can process more than 20 pieces 12-meter-long rebar cage (material preparation, seam welding, reinforcement installation, detection Tube installation, guide pad installation, etc.), the work efficiency is very high.

◆ The processing quality is stable and reliable: due to CNC mechanization, the spacing between the main reinforcement and the winding reinforcement is unifor. the diameter of the steel cage is the same, and the product quality fully meets the specification requirements. In practice, when manually producing steel cages, engineering supervisors go to the processing site for inspections almost every day. when the use pile cge making machine, the supervisors basically implement “inspection-free” on the mechanized steel cages.

◆ There is no need for lap joints to tighten the stirrups, which saves 1.5% of materials compared to manual work, and reduces construction costs.

◆ Since the main reinforcement is evenly distributed on its circumference.it is convenient when multiple reinforcement cages connect. It saves lifting time.

◆ The pile cage making machine is guaranteed in terms of quality control.
