Steel bar rust removal device for building construction

Abstract

The invention discloses a steel bar rust removal device for building construction. The steel bar rust removal device comprises a base, and a reciprocating rotating mechanism for driving a steel bar tomove back and forth and rotate is arranged on the base; the reciprocating rotating mechanism comprises a driving motor and a reciprocating screw rod, a connecting rod is rotationally connected to thereciprocating screw rod, a mounting plate is fixed to the end, away from the driving motor, of the connecting rod, and a chuck for fixing the steel bar is fixed to the mounting plate; and rust removal mechanisms are arranged between the chuck and a supporting sleeve. According to the steel bar rust removal device for building construction, the reciprocating screw rod is used for driving the steelbar to do horizontal reciprocating motion and continuously rotate simultaneously, the multiple sets of rust removal mechanisms are clamped outside the steel bar, all-dimensional grinding and rust removal of the steel bar are achieved, and rust removal is comprehensive and thorough; compared with traditional manual grinding, the steel bar rust removal device has the advantages that the manpower issaved, and the grinding effect is better; and rapid clamping of the steel bar is achieved through the chuck, convenient and rapid dismounting and mounting are achieved, and the rust removal efficiency is high.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a steel bar derusting device for building construction. Background technique [0002] Reinforcement refers to steel for reinforced concrete and prestressed reinforced concrete, which is circular in cross-section and sometimes square with rounded corners. If the steel bar is placed for a long time, it will come into contact with water and air, and iron oxide, that is, rust will appear on the surface. If the rust on the rusted steel bar is not clean, it will affect the load-bearing capacity of the steel bar. Therefore, it is necessary to Derusting the steel bars. [0003] At present, the derusting treatment of steel bars is basically carried out by hand-held sandpaper, which not only consumes a lot of manpower, but also has poor derusting effect. There are also devices for derusting steel bars on the market, but these devices cannot realize all parts of steel bars. ...

[0003] At present, the derusting treatment of steel bars is basically carried out by hand-held sandpaper, which not only consumes a lot of manpower, but also has poor derusting effect. There are also devices for derusting steel bars on the market, but these devices cannot realize all parts of steel bars. The overall rust removal rate is low, and the disassembly and assembly of steel bars is cumbersome, and the rust removal efficiency is low
