Abstract

The invention discloses a light basalt composite fiber board and a subway evacuation platform manufactured from the same, and relates to the technical field of building materials and rail transit. Theproblem that the mechanical property and flame retardancy of an existing evacuation platform pedal are not ideal is solved. The composite fiber board is composed of a composite layer comprising two basalt fiber layers and a resin fiber layer. The subway evacuation platform comprises an evacuation platform surface and a platform support frame, the platform surface comprises H-shaped pultruded profiles and pultruded connection rods, and the H-shaped pultruded profiles and the pultruded connecting rods are formed through pultrusion of composite fiber boards. The fiber board is high in overall strength and also has a certain buffer deformation space so that the fiber board cannot be broken or deformed after repeated extrusion or treading. The basalt fiber layers and the resin fiber layer arealternately stacked, so that the flame retardancy of the whole board is better, and the fiber board is light and environmentally friendly and capable of meeting requirements of a rail transit platformin special environments.

Description

technical field [0001] The invention relates to the technical field of building materials and rail transit, in particular to a lightweight basalt composite fiber board and a subway evacuation platform made thereof. Background technique [0002] The subway tunnel evacuation platform is a special escape channel for the emergency evacuation of passengers when the subway operating trains have an emergency in the tunnel. The evacuation platform is supported and fixed on the inner wall of the tunnel, and its height is equal to the floor of the subway train compartment. When the train stops in distress in the tunnel, passengers can step on the evacuation platform after the train door is opened, and run to the nearest station and out of the tunnel. , and avoid passengers jumping off the train to escape, thereby reducing the probability of secondary accidents. [0003] Foreign outward evacuation platforms mostly use reinforced concrete as the material. At the beginning, China imita...
