Problems solved by technology

Some of the longitudinal beams are in the form of grids, and the cross-section of the grids is generally I-shaped, which has the disadvantages of high cost and inconvenient installation.
The table tops of the existing evacuation platforms are composed of I-shaped longitudinal beams with a certain distance in cross section to form a grid-like platform. This grid-like platform is easy to get stuck on the heels of passengers when passengers escape. Or the belongings dropped by passengers will be leaked under the evacuation platform through the grille gap, or the flames under the platform will escape to the platform through the grille gap, preventing passengers from escaping

Abstract

The invention discloses phenolic glass steel which is prepared from the following components in parts by weight through pultrusion: 70-78 parts of glass fiber yarns, 4-8 parts of continuous glass fiber mats, 15-20 parts of phenolic resin, 0.6-1.1 parts of curing agent, 0.4-0.6 part of promoter and 0.4-0.6 part of iron trioxide, wherein the temperature of a pultrusion mould is 140-280 DEG C. The invention also discloses a subway evacuation platform made of the phenolic glass steel, and the subway evacuation platform includes a grid-type platform and a plate-type platform, wherein the cross section of the grid-type platform is T-shaped, and the countertop of the plate-type platform is a flat surface without a gap on the upper surface. The phenolic glass steel and the subway evacuation platform made of the same, provided by the invention, have the characteristics of light weight, easiness for installation and low production cost, and can meet the requirements for subway environments, namely, low heating value, no smoke or toxin, high strength and high ablation resistance.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and in particular relates to a phenolic glass fiber reinforced plastic and a subway evacuation platform made of the same. Background technique [0002] Due to the special environment of the subway, safety issues are particularly important. In the event of a fire or other emergencies, the escape of passengers is very important. Therefore, corresponding safety measures must be provided during the design and construction of the subway tunnel. Currently, setting up an evacuation platform is a One of the effective measures. Due to the special environment of the subway, the material of the evacuation platform must have sufficient mechanical strength, good fire resistance, no smoke toxicity, high ablation resistance, corrosion resistance, and easy installation and maintenance. [0003] The evacuation platforms commonly used in the subway are mainly made of three kinds of materials: cement, ...
