Description

The utility model relates to transport, in particular to the construction of a double-decker railway passenger car.

The well-known "Double-decker railroad car", the invention of Germany No. DE 102005002701 A1 (filing date 01/19/2005, B61D 1/02, B61D 1/08, published 07/27/2006), containing places for lying, having a lower floor (3 ) with several compartments (3.1) and the upper floor (2) above it with several compartments (2.1), access to which is from the corresponding corridor (2.2, 3.2), moreover, there is one corridor (3.2) on the lower floor and a separate corridor ( 2.2) on the upper floor, and passage in the compartment (3.1) of the lower floor is from the corridor (3.2) on the lower floor, and in the compartment (2.1) he floor of the corridor (2.2) on the upper floor.

The well-known "Double-decker passenger railroad car with compartments for sleeping and / or seating" invention of Germany No. EP 1604880 A1 (application date 09.06.2005, B61D 1/08, B61D 31/00, published 14.12.2005), consisting of a side corridor in a one-story part (3, 3 ') located directly at the height of the landing platform (6), and a two-story part (4) lowered to the floor level (8a) of the lower floor (8), interconnected by stairs (9) .

A disadvantage of the known constructions of wagons is the lack of barriers to the spread of fire between the end single-story and central two-story parts.

As a prototype adopted "Double-decker sleeping passenger car" US patent US 2312906 (A) (filing date 03/28/1943, published 03/02/1943) having end parts with platforms 3 above the trolleys 2 cars, the central two-story part with a row of compartment 12 , the maximum lowered floor 4 and the maximum raised roof 5. Stairs 8 lead from platforms 3 to the lower floor 9, and stairs 10 and 13 lead to the upper floor 6.

The disadvantage of the design of the car adopted as a prototype is the unhindered penetration of flame and combustion products from the end parts with entrance areas with energy supply equipment located in them, which is a source of increased fire hazard, into the central two-story passenger part and the absence of fire-retardant partitions with doors between them allowing to erect an obstacle fire in case of fire.

The objective of the proposal is to create a design for a double-decker passenger railroad car, which prevents the penetration of flames and combustion products from the end single-decker part into the middle two-story part for a period of time allowing passengers to be evacuated from the carriage.

For this, a two-story railway passenger carriage contains end parts located above the trolleys with doors and entrance areas, an average two-story part, including separate compartments for passengers on each floor, longitudinal corridors on each floor, providing access to these compartments and connected by stairs to the entrance areas.

What is new is that the entrance areas are separated from the stairs by vertical fire-retardant partitions with fire-resistant doors, and the roof and walls, in conjunction with the fire-retardant partition, have fire-resistant insulation.

In addition, all the lower and upper compartments have direct access to the corridors, isolated by fire-retardant partitions; the fire resistance of the fire-retarding partition is not less than E30 / I15, where E is the loss of integrity (min), I is the loss of heat-insulating ability (min); the fireproof door is equipped with fireproof glazing.

At the same time, fire-retardant partitions are installed on the floor of the car, with their perimeter along the sides and upper sides adjacent to the inner metal sheathing of the body along the contour: the roof is the side walls, are securely fastened by profiled stops to the floor, the side posts and roof brackets by means of fasteners, and the technological gaps are sealed fire resistant insulation.

The technical result is expressed in the following.

The proposed design allows you to separate the end one-story part with entrance areas from the central two-story part by means of a fire-retardant partition with fire-resistant doors in order to ensure isolation of passenger compartments from rooms with increased fire hazard, providing passage through the wagon and viewing the situation for passengers and maintenance personnel under normal conditions, and in in the event of a fire, it makes it possible to erect a fire barrier, while maintaining fire resistance and flameproofness during evacuation time and out of the car.

A two-story railway passenger car 1 contains end single-storey parts 2, 3 (FIG. 2) located above the trolleys with entrance areas, an average two-story part 4 with a number of passenger compartments 24 and 25, stairs 21, longitudinal corridors 22, 23 on each floor, a fire retardant partition 5, equipped with a fireproof door 6 with a fire resistance of at least E30 / I15, where E is the loss of integrity (min), I is the loss of heat-insulating ability (min) with heat-resistant glazing 7.

The fireproof door is equipped with fireproof glazing.

In the claimed passenger carriage, there may be various options for completing the compartment.

First option.

On the ground floor, rooms with seating can be located, and on the top floor there is a compartment with seating.

The second option.

On the ground floor, compartments with seating areas can be located, and on the upper floor rooms with seating.

The third option.

On the lower and upper floors can be placed rooms with seats.

Entrance areas are separated from the stairs by fire-retardant partitions 5. Fire-retardant partitions 5 are made of slow-burning materials installed on the floor 8 of the car, with its perimeter on the sides and top sides adjacent to the inner lining of the body: the roof 9 - side walls 10, are securely fastened with profiled stops 11 (Fig. 7) to the floor, racks 12 of the sidewalls and brackets 13 of the roof (Figs. 8 and 9), by means of fasteners 14, 15, and the technological gaps 16, 17 are sealed with fire-resistant insulation 18. The roof and walls in conjunction with the fire-retardant in rtikalnoy partition has a fireproof insulation.

The lower 24 (figure 3) and the upper 25 coupe have direct access to the corridors, insulated with fire-retardant partitions.

For the entry and exit of passengers from low platforms, the front door 19 is equipped with steps 20.

Assembly is as follows. In the back of a double-decker passenger railroad car 1, floor 8 is mounted, then a fire retardant partition 5 is installed and it is fastened to the floor by profiled stops 11, brackets 13 and racks 12 by means of fasteners 14, 15. Then technological gaps 16 are sealed with fireproof insulation 18. After that, make further assembly of the car according to the technological process.

Dismantling is carried out in the reverse order.
