Civil engineering I-steel column cross section derusting construction method

Abstract

The invention relates to a civil engineering I-steel column cross section derusting construction method. A rotating shaft sequentially passes through a calibration plate, a frame block a, a crawler disk, a top plate, a frame block b, and a displacement plate; slots are opened in the middle positions of tops of the frame block a and the frame block b; a through rod penetrates through a top plate block, and the two ends of the through rod are respectively placed in the slots of the frame block a and the frame block b; a base block is hinged to one end of a pull rod, and a ball rod is fixed in the middle of the pull rod; the ball end of the ball bar is in contact with the vertical end surface of the displacement plate. The invention adopts the linkage of the top plate, the displacement plateand the clamping member to realize the automatic derusting of the iron brush plate on the I-shaped section steel according to the predetermined trajectory; the iron brush plate can be divided into five kinds of technical means according to the degree of grinding fineness of the cross section of the I-steel, and the welding surface of different types of shapes is polished according to different welding requirements;in addition, the design of the product is simple in structure and easy for the construction personnel to get started.

Description

technical field [0001] The invention relates to a construction method for derusting the section of an I-shaped steel column in civil engineering. 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 thr...

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
