Simple and convenient reinforcing steel bar straightening tool

Abstract

The invention discloses a simple and convenient reinforcing steel bar straightening tool. The simple and convenient reinforcing steel bar straightening tool comprises a straightening head, a handle and a sleeve, and is characterized in that the straightening head comprises a circular plate, three straightening rods, a connecting rod and a holding hoop; the circular plate is a circular steel platewith the diameter of greater than or equal to 140 mm and the thickness of greater than or equal to 12 mm; the three straightening rods are three short reinforcing steel bars; the handle is a second reinforcing steel bar bundle which is formed by bundling, fixing and welding a plurality of reinforcing steel bars together; the reinforcing steel bar location of the second reinforcing steel bar bundleis the same as that of a first reinforcing steel bar bundle; the length of the second reinforcing steel bar bundle is greater than or equal to 1,500 mm; screw threads are formed in one end of the second reinforcing steel bar bundle; the sleeve is a straight threaded reinforcing steel bar sleeve; and the sleeve is connected between the first reinforcing steel bar bundle and the second reinforcingsteel bar bundle through the screw threads. The simple and convenient reinforcing steel bar straightening tool disclosed by the invention has the advantages that the tool is simple in structure and convenient to manufacture; a bent and deformed reinforcing steel bar can be effectively straightened with guaranteed quality and quantity when a reserved reinforcing steel bar is collided so as to ensure the integrity and the functionality of reinforcing steel bar engineering; the straightening tool can be recycled; materials are saved; and the engineering cost is reduced.

Description

technical field [0001] The invention relates to a tool used in the construction of steel bars, in particular to a simple tool for straightening steel bars. Background technique [0002] During the engineering construction process, it is often necessary to leave a certain overlapping length of the steel bars and carry out the construction process twice. Since the steel bars are exposed and have been installed in the corresponding positions, it is very easy to cause bumps on the exposed steel bars during construction in other processes, making the exposed steel bars Deformation and bending of steel bars, especially pile head steel bars and deformation joint steel bars are more serious. The traditional method uses manpower to straighten the steel bars with sticks or steel pipes, and it is difficult to meet the quality requirements, especially in areas where the diameter of the steel bars is thick and the spacing between the steel bars is too dense. It is difficult to operate th...

Problems solved by technology

[0002] During the engineering construction process, it is often necessary to leave a certain overlapping length of the steel bars and carry out the construction process twice. Since the steel bars are exposed and have been installed in the corresponding positions, it is very easy to cause bumps on the exposed steel bars during construction in other processes, making the exposed steel bars Deformation and bending of steel bars, especially pile head steel bars and deformation joint steel bars are more serious. The traditional method uses manpower to straighten the steel bars with sticks or steel pipes, and it is difficult to meet the quality requirements, especially in areas where the diameter of the steel bars is thick and the spacing between the steel bars is too dense. It is difficult to operate the construction under such circumstances, and the existing straightening methods and straightening tools are not rigid enough, the number of end wrenches is small, inconvenient to use, unable to be reused, and low efficiency, which leads to the disadvantages of steel bar spacing and protective layer thickness. Hidden dangers that cannot meet the design and specification requirements further affect the quality and progress of the project

[0003] Therefore, there are above-mentioned inconveniences and problems in known straightening methods and straightening tools
