Background
The reinforcing steel bars are used as important components in building engineering and mainly play a role in bearing and constructing. Because the construction site environment is relatively complicated, and the protection consciousness of workers on the reinforcing steel bars is not perfect enough, the phenomenon that the reinforcing steel bars are bent frequently occurs in the construction process. At present, a common reinforcing steel bar straightening mode is to sleeve a hollow steel pipe into a reinforcing steel bar and to re-straighten a bent part of the reinforcing steel bar by utilizing a lever principle. However, this method cannot handle the inverted U-shaped reinforcing bar because the steel pipe cannot be inserted into the inverted U-shaped reinforcing bar. In order to realize the straightening of the inverted U-shaped reinforcing steel bar, the straightening of the inverted U-shaped reinforcing steel bar is realized mostly by adopting a hollow steel pipe welded with a clamping groove in the current construction side, the clamping groove is directly clamped above a bending part of the inverted U-shaped reinforcing steel bar, and then the bending part of the inverted U-shaped reinforcing steel bar is straightened again by utilizing the lever principle. When the conventional steel bar is straightened, the hollow part of the hollow steel pipe is sleeved into the steel bar as usual, and then the bent part of the steel bar is bent again by utilizing the lever principle.
The steel bar straightening tool formed by the matching of the hollow steel pipes in the clamping groove has the following two defects in the using process: 1) the bottom of the clamping groove is directly welded on the surface of the hollow steel pipe, so that the welding surface is small, other stress supporting points do not exist, and the joint of the clamping groove and the hollow steel pipe is easy to crack due to large stress in the long-term straightening process, so that the connection between the clamping groove and the hollow steel pipe is invalid; 2) because the use needs, the through-hole diameter of hollow steel pipe is generally to set up bigger, when the hollow part of hollow steel pipe emboliaed in the reinforcing bar directly to the reinforcing bar alignment, the part that the reinforcing bar cover was located in the hollow steel pipe lacks the location, when leading to the alignment (break off with the fingers and thumb), the reinforcing bar produces the skew under the condition of atress easily, not only can lead to the dead unstability of alignment in-process, increase the degree of difficulty of alignment operation, and lead to the alignment direction to produce the error easily, lead to the straightness accuracy of the reinforcing bar after the alignment not enough.
Therefore, the clamping piece in the straightening process can be effectively ensured to have enough stress capacity, and the problem of connection failure of the clamping piece in straightening of the inverted U-shaped steel bar is effectively prevented; and can effectively form limit structure in the inside of hollow steel pipe, do not produce the skew when effectively guaranteeing that the steel reinforcement cover is located the alignment in the hollow steel pipe to the portable bar straightening instrument that effectively reduces the alignment operation difficulty of reinforcing bar and effectively improves the alignment effect of reinforcing bar is the utility model discloses a research purpose.
