The invention discloses a steel bar derusting device for building construction. The steel bar derusting device comprises a supporting cylinder, a rotating cylinder is rotatably connected to the top end of the supporting cylinder, rectangular openings are formed in the top positions of the two sides of the rotating cylinder, grinding mechanisms are hinged to the inner walls of the two rectangular openings, the outer wall of the rotating cylinder is sleeved with an adjusting sleeve, a limiting convex block is arranged at the top end position of the side wall of the rotating cylinder, a limitinggroove matched with the limiting convex block is formed in the inner wall of the adjusting sleeve, a driving mechanism used for driving the rotating cylinder to rotate is arranged on the outer wall ofthe supporting cylinder, a lifting handle frame is welded to the side wall of the supporting cylinder, and a horn cover is fixed at the bottom end position of the inner wall of the supporting cylinder through bolts. The circumferential surface of a steel bar can be fully ground, the derusting effect is improved, meanwhile, the adjusting sleeve is arranged in a matched mode, the adjustment is convenient, the steel bars with different specifications can be adjusted, the application range of the device is widened, the flying dust in the derusting process is reduced, a protective cover is arranged in a matched mode, so that the debris is prevented from splashing outside, and more safety is achieved.
Description
technical field [0001] The invention relates to the technical field of building equipment, in particular to a steel bar derusting device for building construction. Background technique [0002] Rebar refers to the steel used for reinforced concrete and prestressed reinforced concrete, whose cross section is circular, sometimes square with rounded corners. Including plain round bars, ribbed bars, twisted bars. Steel bars for reinforced concrete refer to the straight or coiled steel used for reinforced concrete reinforcement. Its shape is divided into two types: smooth round steel bar and deformed steel bar. The delivery state is straight bar and coiled round. Long-term storage of steel bars is prone to rust and needs to be derusted before use. [0003] Most of the existing derusting devices are large in size, inconvenient to carry, and have a small scope of application, so a kind of derusting device for steel bars for building construction is proposed now.
