Portable multi-jacking multifunctional high-tensile reinforcement bar bending and straightening machine and operation method thereof

Abstract

The invention discloses a portable multi-jacking multifunctional high-tensile reinforcement bar bending and straightening machine and an operation method thereof. A jack is adopted as a power mechanism. A vertical handle is arranged on the side wall of a body of the jack. A transverse handle is arranged on a sealing flange of the jack. A detachable bender is arranged at the tail end of an ejector rod of the jack and comprises two slots with different radiuses and a right-deflection-angle slot. A support comprises two symmetrical supporting frames and a reinforcement transverse connector between the two supporting frames. The bottoms of the two supporting frames are provided with supporting bases with steel bar grooves. The plane where the two supporting frames are located is located below the plane where the ejector rod is located. The tops of the two supporting frames are fixedly connected with the sealing flange. The device can carry out bending, straightening construction and preformed deflection angle abutting construction on high-tensile reinforcement bars rapidly, is provided with multiple operation ends, has the good using performance and sufficient power, and can be applied to on-site steel bar abutting, bending, straightening and other procedures such as bending and straightening construction similar to drilling pile horn mouth standard bend manufacturing.

Description

technical field [0001] The invention relates to a steel bar bending and straightening machine, in particular to a portable multi-function high-strength steel bar bending and straightening machine capable of large-area standardized bending, straightening, and deflection angles at the construction site of high-strength steel bars. Background technique [0002] During the construction of the bridge, the main pier cap size of the bridge is large, the diameter of the pile group is large, the distribution is dense, and the diameter of the steel bar is large. For example, the main pier is equipped with 50 D2. In this case, the vertical hook of the bell mouth vertical reinforcement of the bridge bored pile will exceed the casing, which will affect the lowering and positioning of the reinforcement cage, and the expansion of the diameter of the casing will cause waste of concrete. The length of the shaped hook is 24cm. For the D2.0m (reinforcement cage diameter 185cm, steel casing dia...

AI Technical Summary

Problems solved by technology

[0004] The 90° standard elbow at the upper end of the bell-mouth vertical bar of the bored pile of the bridge is made by the back-bending method, and the steel bar has a large diameter and high strength. However, the ordinary bending and straightening process is time-consuming, low in efficiency, and poor in quality, so it does not meet modern fine-tuning requirements. The development requirements of modernization, mechanization and humanization
