Description

A Forming Machine for Rebar Skeleton with Variable Helix Continuous Stirrup with Polygonal Section

technical field

The invention belongs to the technical field of steel frame forming construction in the construction industry, and in particular relates to a forming machine for steel frame with variable spiral continuous stirrup with polygonal cross-section.

Background technique

In the existing construction industry, a special roll welding machine is used to weld the circular cross-section steel frame to weld multiple circular main bars and spiral stirrups wound on the main bar. When the steel bar frame is formed, a driving system is required to drive the main bar as a whole and the existing ones. The formed skeleton rotates relative to the traction system to realize the winding of the stirrups on the main reinforcement. This forming method improves the mechanization level of steel skeleton forming to a certain extent, but there is still a gap with the energy-saving and environmentally friendly production process advocated by the country. At present, the demand for prestressed square piles in the construction market is also expanding, but due to the limitation of processing methods, its output has not been greatly improved. The existing production of square-section steel skeletons also mostly uses steel-skeleton roll welding machines to complete the production. For the forming of polygonal cross-section steel skeletons of different specifications, supporting equipment is needed to complete its large-scale production.

Since the production process of the spiral stirrup directly affects the quality and production efficiency of the steel frame, and the steel frame spiral stirrup produced by the existing steel frame roll welding machine only surrounds the outer periphery of the main bar, for the variable spiral continuous stirrup, the steel frame rolls The welding machine is difficult to meet the requirements. In addition, compared with single-leg spiral stirrups, variable-helix continuous stirrups can improve the bearing capacity and damage resistance of concrete members. For prefabricated variable spiral stirrups, CN101787772B discloses continuous composite rectangular spiral stirrups, that is, the peripheral rectangular stirrups of the spiral structure and the tie bars I and tie bars II of the serpentine structure are continuously wound. , Tie bars I and Tie bars II need to be made separately and reassembled. It is difficult to arrange the stirrups of this structure on the main bars through special mechanical equipment. Therefore, it is necessary to make the spiral stirrups as a whole. Change the shape of a polygonal spiral, and then use special mechanical equipment to enclose it on the main reinforcement to form a steel skeleton with stirrups in a staggered network structure.
