SKU#: Composite Platform for Emergency Evacuation for Subway(Metro)

The composite material evacuation platform is made of phenolic resin as the matrix material and glass fiber roving as the reinforcing material, which is made by pultrusion process. The composite material evacuation platform is mainly composed of grids, beams, inclined beams, handrails, and special connectors are assembled and installed in subway tunnels or on elevated lines. During the operation of the train, in the event of a fire and other emergencies, passengers can escape along with the evacuation platform in an emergency.

During the operation of the train, in the event of a fire and other emergencies, passengers can escape along with the evacuation platform in an emergency.

The composite evacuation platform has high strength, high flame retardancy, low smoke density, low toxicity, lightweight, impact resistance, UV resistance, aging resistance and corrosion resistance, and surface non-slip properties. It can meet the subway environment and has low calorific value, non-smoke toxicity, high strength, high ablation resistance. In addition, to escape platforms and maintenance channels for subway tunnels, composite evacuation platforms can also be widely used in emergency escape channels or operating places such as offshore oil platforms, pedestrian channels, ship decks, and coal mines.

Conditions of Use:

Relative humidity: 30%~90%;

Maximum wind speed: 11m/s;

Vibration: when f<10Hz, the amplitude is 0.3mm; when 10Hz<f<150Hz, the acceleration is 1m/s2;

Load:

Crowd load 5.0kpa:

The maximum reciprocating load generated by the piston wind is 1.0kPa (considering the vertical upward and backward respectively), and the period is 120 seconds;

Deflection:

The allowable deflection value of platform road slab and step ladder pedal is L/200 (L is the span of road slab);

The allowable deflection value of the platform support is L/125 (L is the span of bracket);

The allowable height value of the platform step ladder bracket is L/200 (L is the span of bracket)

Features:

It is made by pultrusion process, has stable performance.

The material has high strength, lightweight, convenient for transportation, and is not easy to damage.

It can be cut and assembled on-site, with simple construction, fast installation speed, and high precision.

The material itself has good aging resistance and long service life.

Comprehensive Comparison of Composite Evacuation Platform Panels and Other Materials

Through a comprehensive comparison of the functional requirements, material performance, modularity, ease of installation, easy-to-adjust size on-site, construction period, maintenance and economy of each plan of the evacuation platform, the details are as follows:

 Material

RC

Composite

Cement-based (inorganic composite type)

RPC(Active powder concrete)

Components

Putting steel bars in the concrete to act in the same direction to improve the concrete force

It is made of phenolic resin as the matrix material and glass fiber roving as the reinforcing material. It is made by the glass fiber reinforced plastic composite material pultrusion process.

Cement is the base material, chopped glass fiber is used as reinforcement, special external static is used as modified material, aggregates, admixtures and water are added

Composed of cement, high-quality quartz sand, silica powder, superplasticizer, ultra-high-strength special steel fiber, etc., prepared by high-temperature steam curing and other specific processes

Production and installation

Bulk, assembly generally requires the help of machinery, difficult to install on site, difficult to adjust the size on site,  corners are easy to drop

Lightweight, simple to assemble, convenient on-site adjustment; small dead weight, need to be specially fixed to resist wind pressure

It is convenient to install and transport, and it can be cut on site; the weight of a single block is large, and it is easy to install on site

Lightweight, can be cut on site, easy to install

Maintenance
