Mechanical equipment for manufacturing spring-shaped erection hoop reinforcement

Abstract

The invention discloses a novel vertical stirrup used in construction, consisting of a reinforcing steel bar, wherein the overall structure is shaped like a spring. The starting end of the stirrup is a closed rectangle, wherein the protruding end of the rectangle forms a hypotenuse with the angle of the rectangle. The end of the hypotenuse is folded to form a trilateral rectangle which is in parallel with the closed rectangle. The protruding end of the trilateral rectangle is folded again to form another hypotenuse which is in parallel with the hypotenuse. The structure is copied until the terminal of the stirrup forms a closed rectangle. The invention also discloses a machine used to produce the novel vertical stirrup used in construction, and the machine consists of a frame, an electromotor arranged on the frame, a gearbox, a power gear and a forming gear of vertical stirrup which is meshed with the power gear. The forming gear of vertical stirrup is arranged on a central locating column, and the forming gear of vertical stirrup is provided with a shape regulating cock which is arranged in X-shape, wherein the regulating cock is provided with four regulating grooves symmetrically around the central column and each regulating groove is provided with an eccentric regulating cam inside.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular, the invention relates to a mechanical device for manufacturing spring-shaped erecting stirrups. Background technique [0002] At present, the loaded steel bars of the columns and beams of the building concrete structure are arranged according to the stress mode of the concrete columns and the concrete beams. If these stressed steel bars are to form a steel cage according to the design requirements, it must be realized by erecting steel bars (commonly known as stirrups), that is, steel bars of corresponding diameters are made into rectangular or polygonal, T-shaped, etc. Steel hoops (consistent with the shape of the concrete structure), and then combined with the main reinforcement of the load for binding, so as to complete the production and construction of the stressed reinforcement cage. This is the only traditional construction method at present, but this traditional const...

AI Technical Summary

Problems solved by technology

[0003] 1. The production process of erecting stirrups is backward, and the processes from extension, pulling to cutting as required are almost all manual and semi-mechanized operations, so there is a problem of low work efficiency

high material consumption

[0004] 2. The traditional stirrup is a single individual, and each stirrup has a joint, so that each stirrup consumes more than 10 centimeters of steel

[0005] 3. The traditional stirrup is a single rectangle, and its production process is extension, straightening, cutting, and bending. The production speed of a stirrup is slow, the efficiency is low, and the degree of mechanization is not high.
