Abstract

The utility model discloses an instrument of crooked reinforcing bar, including lever, fixed pivot, roll fulcrum, the lever is the member, the quarter butt of fixed pivot for being equipped with " V " shape and bending, and the quarter butt of roll fulcrum for being equipped with the gyro wheel, the fixed pivot is parallel to each other with the axis of roll fulcrum quarter butt, and fixed pivot vertical welding an in end of lever, and the roll fulcrum sets up with the fixed pivot interval and welds on the lever. The utility model designs a have the lever of fixed pivot and roll fulcrum, set up " V " shape and bend on the fixed pivot, set up the gyro wheel on the roll fulcrum for the bending point that the reinforcing bar is crooked should control, and crooked direction is easily mastered with the roughness, has to alleviate intensity of labour, high, the cloth muscle advantage of high quality of work efficiency.

Description

A kind of instrument of moment reinforcement

Technical field

The utility model relates to the instrument of technical field of building construction, especially a kind of instrument of moment reinforcement.

Background technology

In civil buildings construction, cloth muscle work before concrete construction is absolutely necessary link, in cloth muscle process, except prefabricated to reinforcing bar enforcement, in colligation job site, implementing bending to reinforcing bar is also conventional means, especially after square pile concrete chisel removal, needs bar bending upright in square pile in raft foundation.Prior art is exactly that Problems existing is, the bending point of bar bending should not control with manpower stooping one by one, and bending direction and flatness are not easily grasped, cause labour intensity greatly, inefficiency, cloth muscle defect of low quality.

Utility model content

The purpose of this utility model is the instrument of a kind of moment reinforcement provided for the deficiencies in the prior art, the utility model devises the lever with fixed pivot and rolling fulcrum, fixed pivot arranges the bending of " V " shape, rolling fulcrum arranges roller, the bending of bar bending point should be controlled, bending direction and flatness are easily grasped, have reduce labor intensity, operating efficiency is high, the measured advantage of cloth muscle matter.

The concrete technical scheme realizing the utility model object is:

A kind of instrument of moment reinforcement, its feature comprises lever, fixed pivot, rolling fulcrum, described lever is rod member, fixed pivot is for being provided with the quarter butt of " V " shape bending, rolling fulcrum is the quarter butt being provided with roller, the axis of described fixed pivot and rolling fulcrum quarter butt is parallel to each other, and fixed pivot vertical welding is in a termination of lever, and rolling fulcrum and fixed pivot interval arrange and be welded on lever.

The utility model devises the lever with fixed pivot and rolling fulcrum, fixed pivot arranges the bending of " V " shape, rolling fulcrum arranges roller, the bending of bar bending point should be controlled, bending direction and flatness are easily grasped, have reduce labor intensity, operating efficiency is high, the measured advantage of cloth muscle matter.

Detailed description of the invention

Consult Fig. 1, Fig. 2, Fig. 3, the utility model comprises lever 1, fixed pivot 2, rolling fulcrum 3, described lever 1 is rod member, fixed pivot 2 is for being provided with the quarter butt of " V " shape bending, rolling fulcrum 3 is for being provided with the quarter butt of roller, described fixed pivot 2 is parallel to each other with the axis of rolling fulcrum 3 quarter butt, and fixed pivot 2 vertical welding is in a termination of lever 1, and rolling fulcrum 3 and fixed pivot 2 interval arrange and be welded on lever 1.

The utility model uses like this:

Consult Fig. 1, Fig. 4, Fig. 5, the utility model is used for the cloth muscle process of construction, in assembling reinforcement job site, bending is implemented to reinforcing bar, especially after square pile concrete chisel removal, now, because reinforcing bar density is comparatively large, the bending point of each root reinforcing bar and wrap direction all there are differences, below for by bar bending upright in square pile to the course of work in raft foundation, further illustrate as follows to application of the present utility model;

To choose in square pile a upright plan bend reinforcement 4, the fixed pivot 2 of lever 1 is placed in the inner side of intending bend reinforcement 4 bending direction, and make " V " shape bending on fixed pivot 2 be stuck on the bending point of plan bend reinforcement 4, the rolling fulcrum 3 of lever 1 is placed in the outside of intending bend reinforcement 4 bending direction, and make the roller of rolling fulcrum 3 be positioned at the crooked position intending bend reinforcement 4, firmly rotating lever 1, make lever 1 towards the bending direction bending intending bend reinforcement 4, until the wrap direction of plan bend reinforcement 4 and flatness all meet designing requirement, bending reinforcement upright in square pile completes, successively bending is implemented to next root reinforcing bar, and complete all plan bend reinforcement 4.

The utility model is provided with the bending of " V " shape on fixed pivot 2, during bending, " V " shape bending on fixed pivot 2 is stuck on the bending point of plan bend reinforcement 4, at rotating lever 1 of exerting oneself, make lever 1 towards when intending the bending direction bending of bend reinforcement 4, " V " shape bending on fixed pivot 2 significantly improves with the contact strength intending bend reinforcement 4 bending point, implements in Forging Process, the bending of bar bending point is firmly controlled, the point of bending exactly can be obtained.

The utility model is provided with roller on rolling fulcrum 3, during bending, rolling fulcrum 3 is placed in the crooked position intending bend reinforcement 4, at rotating lever 1 of exerting oneself, make lever 1 towards when intending the bending direction bending of bend reinforcement 4, roller on rolling fulcrum 3 rolls and coordinates on the crooked position intending bend reinforcement 4, frictional force between the crooked position of the roller on rolling fulcrum 3 and plan bend reinforcement 4 is significantly reduced, implement in Forging Process, the process of bending reinforcement is saved time, laborsaving, and to be beneficial to the plan wrap direction of the bend reinforcement 4 and control of flatness.
