Composite material subway evacuation platform

Abstract

The invention discloses a composite material subway evacuation platform. The evacuation platform comprises an evacuation platform body and an evacuation platform support, wherein the evacuation platform body is formed by arranging and assembling four platform unit plates; the evacuation platform body is an integral plate formed at a time through a pultrusion process; the four platform unit plates are each provided with a cavity; the evacuation platform body is provided with an anti-skid platform face; the anti-skid platform face is provided with anti-skid protruding strips; U-shaped grooves which are symmetrical about the center of the evacuation platform body are formed in the positions, close to the inner sides of the cavities in the outer sides, of the two sides of the bottom face of the evacuation platform body; and the evacuation platform support is arranged at the bottom of the evacuation platform body. The composite material subway evacuation platform is the integral plate formed at a time through the pultrusion process, the surface is closed, the surface of a standard product is an anti-skid face, and the platform face is provided with the anti-skid protruding strips. Due to the fact that the forming process of a die for producing the product is one-time forming, continuity and integrity are very good, the labor cost and labor intensity are greatly reduced, and the production efficiency and product quality are improved.

Description

technical field [0001] The invention relates to the technical field of evacuation platforms, in particular to a composite material subway evacuation platform. Background technique [0002] At present, there are three main schemes for the evacuation platform of the underground section of the subway in China: 1. Prefabricated cement-based structure; 2. Prefabricated reinforced concrete structure; 3. Composite material structure. [0003] In terms of composition and connection mode, the cement-based platform is lapped on the cement-based pier at both ends, and the cement-based pier is fixed on the tunnel wall through anchor bolts, so its strength is high, but the disadvantage is that it needs to make molds, cast molding, and maintain The cycle and production cycle are long, cutting is inconvenient, and the buttresses are made of fixed molds, which are not suitable for the changeable arc horseshoe. In the prefabricated reinforced concrete structure, the platform is lapped on th...

Problems solved by technology

[0003] In terms of composition and connection mode, the cement-based platform is lapped on the cement-based pier at both ends, and the cement-based pier is fixed on the tunnel wall through anchor bolts, so its strength is high, but the disadvantage is that it needs to make molds, cast molding, and maintain The cycle and production cycle are long, cutting is inconvenient, and the buttresses are made of fixed molds, which are not suitable for changing curved horseshoe shapes

In the prefabricated reinforced concrete structure, the platform is lapped on the horizontal support piers at both ends, and the support piers lean on the shield segments. It has the advantages of high strength and good fire resistance, but the disadvantage is that the construction period is long and the cost is high
