Description

Technical Field

[0001] The utility model belongs to the technical field of engineering construction, and in particular relates to a short steel bar segment bending device. Background Art

[0002] During the construction of the wharf project, short steel bars are often bent. If there is no short steel bar bending machine on site, the short steel bars are usually placed on the ground, and then the workers step on one end of the short steel bar with one foot and lift the other end of the short steel bar with their hands to bend the short steel bar. This not only wastes the workers' physical strength, but also affects the progress of the project due to low efficiency when there are many short steel bars to be bent. It may even cause blisters on the workers' feet that step on the short steel bars, affecting the workers' health.

[0006] The hinge support is composed of two coaxially arranged nuts, and the rotating shaft is made of a screw rod.

[0007] The supporting platform adopts a single-leg iron table, the tabletop is made of a steel plate, the supporting legs are made of steel pipes, and the supporting legs are inserted and fixed on the ground.

[0008] The ferrule is made of a rectangular steel pipe.

[0009] The cross section of the stopper is a right-angle trapezoid.

[0010] The utility model has the advantages and technical effects of using the stopper and the sleeve on the inclined surface as the support fixing point, using the pressure rod and the pressure plate as the wrench, so that workers can easily bend the short steel bar segment, simple operation, safe use, high efficiency, low labor intensity, and no injury to workers. At the same time, the utility model has a simple structure, the materials used are easy to obtain at the construction site, the production is simple, the cost is low, and it can be used in a turnover manner.
