Problems solved by technology

Four: Mechanical rust removal, manual rust removal is slow and inefficient, the disadvantage of chemical rust removal is that the rust removal effect cannot be ideal, and it may pollute the environment if it is not handled properly
However, the steel plate after derusting is easy to return to rust, so it must be coated with a special wet derusting coating, which has a great influence on the coating of general performance coatings.
Although the above-mentioned mechanical rust removal methods are more practical, it becomes helpless for the cross-section rust removal of the I-beam that has been poured on the concrete foundation, because it is actually open-air, and the distance between the steel columns is large, and the equipment for rust removal Difficult, the current method is to weld with manual sand paper, this method greatly reduces the original design load strength of the steel column

Abstract

The invention relates to a derusting construction method for the cross section of a constructional steel I-column. A rotary shaft penetrates through a calibration disc, a frame block a, a track disc,a top disc, a frame block b and a deflection disc in sequence, and slots are formed in the middles of the tops of the frame blocks a and b respectively; a through rod penetrates through a top plate block, and the two tail ends of the through rod are arranged in the slots of the frame blocks a and b respectively; a base block is hinged to one end of a pull rod, a ball screw is fixed to the middle of the pull rod, and the ball end of the ball screw abuts against the vertical end face of the deflection disc. According to the derusting construction method, through linkage of the top disc, the deflection disc and a clamping piece, an iron brush plate can automatically derust the i-section steel according to a preset locus; the technological means that iron brush plates can be classified into five specifications according to different I-steel section grinding fineness degrees is adopted, and it is achieved that welding faces in different shapes can be ground according to different welding requirements; besides, the designed product is simple in structure, and constructors easily get started.

Description

technical field [0001] The invention relates to a construction method for derusting the cross section of a building I-shaped steel column. Background technique [0002] Metal rust removal methods can be divided into four categories: 1: Manual rust removal. Two: chemical rust removal. Three: Ultrasonic derusting. Four: Mechanical rust removal, manual rust removal is slow and inefficient, and the disadvantage of chemical rust removal is that the rust removal effect cannot be ideal, and it may pollute the environment if it is not handled properly. The choice of rust removal method should be based on various factors such as environment and effect. It is unscientific to say that a certain method is better than bad. Mechanical derusting is generally divided into four types: shot blasting, electric derusting, sandblasting and high-pressure water abrasive derusting. 1. Shot blasting rust removal, shot blasting rust removal is to use the high-speed rotating impeller to throw abra...
