Rust removing device for steel I-column embedded in building foundation

Abstract

The invention relates to a rust removing device for steel I-column embedded in a building foundation. A rotating shaft sequentially penetrates through a calibration disc, a support block a, a track disc, a top disc, a support block b and a shift disc, wherein slots are formed in middles of tops of the support block a and the support block b, a penetrating rod penetrates through a top plate block, and two tail ends of the penetrating rod are placed in the slots of the support block a and the support block b respectively; a base block is hinged with one end of a pull rod, a ball rod is fixed in the middle of the pull rod, and a ball end of the ball rod abuts against the annular surface of the shift disc. An iron brush plate can automatically remove rust on I-shaped section steel according to a preset track through linkage of the top disc, the shift disc and a clamping part; different kinds of welding faces are polished according to different welding requirements by using the technical means that the iron brush plate can be divided into 2-5 specifications according to different I-steel section polishing fineness; besides, the designed product is simple in structure and easy to operate by constructors.

Description

technical field [0001] The invention relates to a derusting device for pre-embedded I-shaped steel columns of building 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 t...

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
