Portable round steel bending device

Abstract

The invention provides a portable round steel bending device. A body structure is formed by a high-pressure oil cylinder, a support, pull rods, hanging basket screws and the like. Auxiliary facilities are not needed. The stretching part of round steel, with the diameter phi ranging from 10 mm to 30 mm, embedded in a high-rise building can be bent through operation of one person, a reinforced concrete structure is not damaged at all, and the portable round steel bending device can further replace an existing common pipe bending machine for mass machining on common occasions. The bending device is simple and practical in structure, low in manufacturing cost, light, large in load, capable of saving energy and labor and convenient to use, and thus an ideal equipment choice is provided for building construction.

Description

technical field [0001] The invention belongs to the category of tooling accessories. Specifically, it is a device for bending the protruding part of the round steel pre-embedded in the reinforced concrete structure during the high-rise construction of the building site. Background technique [0002] Existing buildings are reinforced concrete high-rise structures. During construction, a large number of round steels of various specifications need to be bent at various angles. Among them, it is very difficult to rebend the protruding parts of the round steels that have been embedded in the reinforced concrete structure. The bending force exerted during the bending of round steel is difficult to guarantee the performance of the poured concrete structure, and the existing various bending equipment cannot fully adapt to the special restrictions and needs of the construction site. [0003] Such as large-scale hydraulic bending machines, medium-sized mechanical bending machines, et...

Problems solved by technology

[0002] Existing buildings are reinforced concrete high-rise structures. During construction, a large number of round steels of various specifications need to be bent at various angles. Among them, it is very difficult to rebend the protruding parts of the round steels that have been embedded in the reinforced concrete structure. The bending force applied when bending the round steel is difficult to guarantee the performance of the poured concrete structure, and the existing various bending equipment cannot fully adapt to the special restrictions and needs of the construction site

[0003] Such as large-scale hydraulic bending machine, medium-sized mechanical bending machine, etc., due to their large volume, many ancillary facilities, and high quality, they cannot meet the needs of on-site construction in high-rise narrow spaces.

[0004] Another example is the small pipe bending machine, because of its own strong support point, it cannot be displaced with the bent workpiece, and it is not suitable for the re-bending of embedded parts in building construction.
