Rust removal construction method for road I-shaped steel foundation

Abstract

The invention relates to a rust removal construction method for road I-shaped steel foundation. A rotating shaft sequentially penetrates through a calibration disc, a frame block a, a crawler disc, atop disc, a frame block b and a displacement disc; seam slots are formed in the middles of the tops of the frame block a and frame block b respectively, a through rod penetrates through a top plate block, and the two tail ends of the through rod are placed in the seam slots of the frame block a and frame block b respectively; a base block is hinged to one end of a pull rod, a rolling ball rod is fixed in the middle of the pull rod, and a rolling ball end of the rolling ball rod abuts against the vertical end face of the displacement disc. According to the method, linkage among the top disc, the displacement disc and a clamping member is adopted so that an iron brush plate can conduct derusting automatically on an I-shaped section steel material according to a predetermined trajectory; by adopting the iron brush plate, technical means with 2-5 specifications can be obtained according to the grinding fineness degree of an I-shaped steel section, and welding surfaces different in type andshape can be ground for meeting different welding requirements; in addition, a product designed by means of the method is simple in structure, and convenience is provided for construction personnel during work.

Description

technical field [0001] The invention relates to a construction method for derusting road I-beam foundations. 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 abrasives to the steel surface to ...

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
