Problems solved by technology

The burning time of the flame retardant test shall not be less than the time required to evacuate the passengers from the vehicle (the nominal test time shall not be less than 15 minutes). Considering the matching with the evacuation capacity of the train, it is recommended that the standard of the fire barrier shall be at least 45 minutes. The floor structure is no longer suitable for urban rail vehicles with modern high-standard fire protection requirements

Embodiment Construction

[0023] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0024] Such as Figure 3 to Figure 5 As shown, a floor structure of a rail vehicle includes a car body chassis structure 1 , a floor cloth 2 , a heat insulating material 3 and a metal plate 5 .

[0025] Wherein, the car body underframe structure 1 includes a hollow profile layer 6 on the upper floor and a suspension beam layer 7 on the lower floor, and the two sides of the car body underframe structure are also provided with underframe side beams 12. In urban rail vehicles, The hollow profile layer 6 generally adopts aluminum profiles. The hollow profile layer 6 includes an upper aluminum plate 8, a lower aluminum plate 9 and a middle reinforcing rib 13, and the hanging beam layer 7 includes a beam 10 and a longitudinal beam 11 for hanging equipment under the vehicle, and also includes a corbel (not shown in the figure). ) etc., the beam 10 an...

Abstract

The invention relates to a floor structure of a rail vehicle, which comprises a car body chassis structure, a floor cloth, a heat insulating material and a metal plate, the floor cloth is laid on the upper surface of the car body chassis structure, and the car body The lower layer of the underframe structure is provided with the heat insulating material, and the metal plate is laid on the lower surface of the heat insulating material, and the metal plate is fixedly connected with the vehicle body underframe structure. The overall structure of the present invention is simple and light in weight. Heat insulating materials and stainless steel metal plates are laid under the chassis structure, and the bottom metal plate directly faces the flame in case of fire, making full use of the high melting point of stainless steel to delay the car body structure. The collapse of the car body can be effectively protected, especially for the aluminum alloy car body with a low melting point.

Description

technical field [0001] The invention relates to a floor, in particular to a floor structure with a fireproof function used on rail vehicles such as urban rails, and belongs to the technical field of rail vehicles. Background technique [0002] Such as figure 1 and figure 2 As shown, the conventional practice for the floor structure of rail vehicles is to lay heat and sound insulation materials on the upper layer of the car body chassis structure (ie, inside the passenger compartment), and then lay the interior anti-slip and flame-retardant floor cloth. [0003] figure 1 The one shown is a ceramsite sand structure. A heat insulating material 3 is arranged above the vehicle body chassis structure 1, and a layer of floor cloth 2 is laid on the top of the heat insulating material 3. In this structure, the heat insulating material 3 is made of ceramsite sand. figure 2 Shown is a suspended floor structure, a heat insulating material 3 is set above the vehicle body chassis str...
