Detailed Description

In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention more clearly understood, the following description is given in conjunction with the accompanying drawings and embodiments to illustrate the present invention in further detail. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1 and fig. 2, a waterproof structure for a coal transporting trestle steel bottom plate according to the present invention will now be described. Coal conveying trestle is waterproof construction for steel bottom plate, including setting firmly the steel sheet main part 20 in coal conveying trestle 10 inside. Further comprising a primer layer 30, an elastic waterproof layer 40 and a protective layer 50. The primer layer 30 is coated on the upper surface of the steel plate body 20, and is used for preventing corrosion of the surface of the steel plate body 20. The elastic waterproof layer 40 is laid on the upper surface of the steel plate body 20 and coated on the primer layer 30 on the upper surface of the steel plate body 20. The protective layer 50 is fixed above the elastic waterproof layer 40, and is used for a containing groove for placing a conveyor and preventing the elastic waterproof layer 40 from being damaged by coal blocks falling from the conveyor.

Coal conveying trestle 10 is prior art, has open and half open, and steel sheet main part 20 sets up for supporting with coal conveying trestle 10, and steel sheet main part 20 sets up the below in coal conveying trestle 10 inside usually, and sets firmly on coal conveying trestle 10.

When the primer layer 30 is coated, since the steel plate body 20 is in a severe environment for a long time, a large amount of rust is contained on the upper plate surface, and the rust needs to be cleaned first, and then the primer layer 30 is coated. Preferably, the primer layer 30 is a rust conversion cured primer layer 30, and the effective components in the rust conversion cured primer layer 30 react with rust to generate a compact and stable rust chelate, so as to achieve the purpose of rust prevention.

The elastic waterproof layer 40 is made of an elastic waterproof coating material such as: high polymer modified asphalt rubber waterproof anticorrosive paint, polyurea, polyurethane and the like.

The protective layer 50 may be a high-ductility concrete material.

The utility model provides a coal conveying landing stage is waterproof construction for steel bottom plate, compare with prior art, the utility model discloses coal conveying landing stage is waterproof construction for steel bottom plate with priming paint layer 30 coating at the last face of steel sheet main part 20, can guarantee to form protective layer 50 at the last face of steel sheet main part 20 to protect steel sheet main part 20, can prevent to a certain extent that steel sheet main part 20 is corroded. The elastic waterproof layer 40 is disposed above the steel plate main body 20 and between the primer layer 30 and the protective layer 50, so that the influence of the vibration of the bracket or the steel plate main body 20 on the protective layer 50 can be reduced due to the elastic action of the elastic waterproof layer 40, and the protective layer 50 is prevented from being damaged. The utility model provides a coal conveying landing stage is waterproof construction for steel bottom plate can alleviate the vibrations effect to protective layer 50 through setting up priming paint layer 30, elastic waterproof layer 40 and protective layer 50 on steel sheet main part 20, can effectually protect steel sheet main part 20 simultaneously, and steel sheet main part 20's anticorrosive water-proof effects is good, and the practicality is strong.
