Wear-resistant and corrosion-resistant composite structure straddle type monorail track beam

Abstract

The invention belongs to the related technical field of track beam bodies, and discloses a wear-resistant and corrosion-resistant composite structure straddle type monorail track beam. The wear-resistant and corrosion-resistant composite structure straddle type monorail track beam comprises a beam body. The beam body is of an I-shaped hollow structure. The wear-resistant and corrosion-resistant composite structure straddle type monorail track beam also comprises an undercoat layer and a protective layer which are connected. The undercoat layer is arranged on the outer surface of the beam body.The undercoat layer covers the outer surface of the beam body. The protective layer is arranged on the surface, away from the beam body, of the undercoat layer, and the protective layer covers the undercoat layer. The material used for the undercoat layer is compatible with the material used for the protective layer. The wear-resistant and corrosion-resistant composite structure straddle type monorail track beam is good in protective performance, high in adaptability, high in flatness, good in wear resistance, simple in structure, and convenient to maintain.

Description

technical field [0001] The invention belongs to the technical field related to track beams, and more specifically relates to a straddle type monorail track beam with a wear-resistant and corrosion-resistant composite structure. Background technique [0002] As an important part of straddle-type monorail traffic, track beams have their own protection capabilities, surface accuracy, service life, and color appearance. They are very important for applications in complex terrain and harsh environments, and they are also important for operational safety, cost, and aesthetics. Greater impact. [0003] At present, the structure of track beams used in the field of straddle rail transit is mainly divided into two types: steel structure and reinforced concrete structure. In practical application, the surface of steel structure track beams will be pre-coated with anti-corrosion The waterproof performance of the paint is not good, and it is easy to age and fall off. The wear resistance...

[0003] At present, the structure of track beams used in the field of straddle rail transit is mainly divided into two types: steel structure and reinforced concrete structure. In practical application, the surface of steel structure track beams will be pre-coated with anti-corrosion The waterproof performance of the paint is not good, and it is easy to age and fall off. The wear resistance of ordinary anti-skid coatings is not good, and it will be worn and consumed quickly under the condition of frequent passing vehicles. At the same time, it also brings a lot of pressure to daily maintenance; the reinforced concrete structure track beam has basically no protective treatment on the surface in practical application, and rainwater can easily seep into the beam body through the gap, causing corrosion of the steel bar and affecting the strength and life of the beam body. At the same time, the surface of the track beam is easily damaged by environmental erosion, which affects the smoothness of the running surface and reduces the ride comfort. The exposed reinforced concrete surface is also easy to absorb stains and appear stains, which affect the appearance. Clean and maintain difficulty
