Abstract
A platform door arrangement with a traffic route (1), a railroad platform (2), a partially raised partition (3) between the platform (2) and the traffic route (1) and platform doors (31) arranged in the partition wall (3). The traffic route (1) and the platform (2) are arranged within a housing having a ceiling (22), or within a subway. An air exchange occurs between the traffic route (1) and the platform (2) via a free space (30) between the partially raised partition (3) and the ceiling (22). The free space (30) is closed off in an air permeable manner from above the partially raised partition (3) up to the ceiling (22).
Description
- Underground and above-ground transport stops, especially for subway trains, are increasingly being planned and built with platform doors. The main reasons for this are for protection against moving accidents (suicide or foreign influences) and/or protection against garbage in the traffic area (ignition sources or ignition devices in connection with hot braking devices on the vehicle as well as with electrical current-carrying systems).
- In the prior art, distinction is basically made between two types of platform doors. On the one hand, there are closed systems with a partition from the platform to the ceiling in which the platform doors are arranged. On the other hand, there are non-closed systems with a partial raised partition, in which the platform doors are arranged. Above the partition wall, a free space remains to the ceiling, which serves for air exchange between the platform area and the traffic route.
- Enclosed partitions with platform doors permit an aerodynamic separation of the tunnel corridor of the traffic route from the platform area of the stop. The separation makes it possible to control ventilation and air conditioning in the tunnel corridor of the traffic route separately from the stations or stops. This is advantageous for the air-conditioning of stations or stops, since heat/cold is not transported from the station into the tunnel corridor by the piston effect of the vehicles traveling in the tunnel corridor. In the event of a vehicle fire in the station, provision must be made that, with the vehicle and platform doors open, the escaping smoke should not fill the escape routes. For this purpose, the tunnel and the stop area must be ventilated separately.
- Partially raised partitions do not allow aerodynamic separation of the tunnel from the waiting area of the stop. In a fire, smoke extraction systems can be used in the traffic route, mostly above the tracks. Advantageously already existing ventilation concepts can be used for the retrofitted provision of stops with partially raised partition walls with platform doors.
- The invention relates to a platform door arrangement with a traffic route, a platform, a partially raised partition wall between the platform and the traffic route, and platform doors arranged in the partition wall, wherein the traffic route and the platform are arranged within a housing having a ceiling or in a subway, and between the traffic route and the platform a free space remains between the partially raised partition and the ceiling.
- However, it is disadvantageous with partially raised partition walls that people with suicidal intent, or acting on a test of courage, or in order to obtain unauthorized access to a stretch of tunnel, can still get into the protected traffic area by means of the partition wall. Furthermore, objects and waste, for example newspapers, packaging and cigarettes, can be thrown over the partition into the traffic control area. These objects present a risk of accidents and fires.
- JP 2002 89916 A describes a railway station door arrangement with a closed partition between the platform and the traffic route, and which has an air duct system parallel to the traffic route and platform above the station platforms. Air conditioning systems are installed in the air duct, which allow air cooling for the area of the platform. In an emergency, the air duct system is used to extract any smoke and gases. This air duct system uses a new air duct design, so that existing systems, which require air exchange between the traffic route area and the platform, have to be remodeled with considerable effort.
-
DE 10 2014 114 068 A1 discloses a ventilation grille closure for a vehicle with adjustable ventilation grille flaps which can be actuated by an electromechanical actuator. - It is therefore an object of the invention to provide a railroad station door arrangement which, on the one hand, reliably separates the traffic route from the platform and thus also makes it impossible to penetrate the partition wall and on the other hand can operate with conventional smoke extraction systems in the traffic area, generally air ducts and exhaust systems provided above the railroad tracks.
- This object is achieved by a railroad or railway platform door arrangement according to claim 1.
- If the free space above the partially raised partition wall is air-permeably closed up to the ceiling, any smoke gases entering the platform area can be removed by conventional smoke extraction systems in the traffic area (for example, above the tracks) since an aerodynamic coupling between the platform and the traffic route is possible through the air-permeable closure. On the other hand, no persons or objects can enter the traffic control area via the partition.
- If the air-permeable closure has grille elements, the task is solved in a simple manner by means of the grille elements.
- In order to promote flue gas extraction, in particular above the platform doors, for example in the case of a burning train in the track area with open platform doors, the grille elements are arranged above each platform door.
- In order to guide the airflow above the platform door in the direction of the exhaustion of the smoke extraction system, the grille elements can be designed as profiled guide plates.
- In a further embodiment, the grille elements are, as required, closable ventilation grilles. Therewith, it is possible to combine the benefits of a closed railroad platform arrangement, namely the climatic separation between the platform area of the stop and the traffic area, with the advantages of the partially raised partition, namely, the possibility that in the event of a disturbance, in particular a fire, smoke can be removed via a conventional ventilation system, since the grille elements then automatically self-open. For this purpose, a corresponding sensor system with control of the lockable ventilation grilles can be provided.
- Particularly preferably, the lockable ventilation grille has an actuator or other suitable drive which actively closes the grille element when a sensor signal is present, the ventilation grille being open in the rest state. This ensures that, in the event of faults in the control, the lockable ventilation grilles are automatically dropped into their resting state, that is, they are opened and thus enable air exchange. This is particularly useful for safety reasons for a possible smoke extraction of the platform as well.
- Since air-impermeable closure elements are provided in addition to the grille elements for the air-permeable closure, the air-permeable region in the free space above the partially raised partition wall can be limited. Particularly in connection with lockable ventilation grilles, the advantages of closed partitions and partially raised partitions can thus be combined with reasonable effort.
- If, in addition to the air-permeable closure above the partially raised partition wall, air openings are provided in the partition at the bottom near the platform, the aerodynamic coupling between the platform area and the traffic area can be reinforced. Pressure differences, for example, of preceding trains, can thus be even more effectively compensated for.
- If lights, signs, loudspeakers, cameras, switches, communication means and/or monitors are arranged on the grille elements and/or the closure elements of the air-permeable shutter, the platform lighting, possible signposting, for example for escape routes as well as announcements, monitoring and information transmissions can be provided at a particularly dominant and conspicuous place.
- Due to the fact that the platform doors are anchored with structural elements also on the ceiling, the aerodynamic forces (resulting from changing air pressure differences) generated by the vehicle movements can be transmitted in a relatively simple structure into the building body. In contrast to otherwise customary partially raised partition walls, which are only anchored in the floor of the platform, a considerably lighter and therefore more cost-effective construction can be selected.
- Continuous structural elements between the platform and the ceiling can also be used for grounding purposes.
- An exemplary embodiment of the invention is described in detail below with reference to the appended figures.
- Therein:
-
FIG. 1 is a cross-sectional view of a platform door arrangement in a subway station and -
FIG. 2 is a view of the platform door arrangement shown inFIG. 1 . -
FIG. 1 shows a cross-section of a subway station with a traffic route 1 in the form of railroad tracks in a tunnel. In the vicinity of the stop, aplatform 2 with aplatform edge 21 is provided adjacent the traffic lane 1. Apartition 3 is provided between theplatform 2 and the traffic route 1 near theplatform edge 21. The dividingwall 3 divides the subway station into atraffic area 10 and aplatform area 20. Thepartition wall 3 has a corresponding fit to theplatform doors 31 which are aligned on the traffic route, here the tracks for subway trains, which open only when subway train assigned the subway station is stopped at theplatform 2 and its doors open. In this case, the doors of the subway train are in coincidence with theopen platform doors 31 of thepartition 3. Before the train leaves, therailroad platform doors 31 close, as well as the doors of the subway train U which is represented here only in dash-lines. - The
partition wall 3 is designed as a so-called partially raised partition, so that aclearance 30 forms above thepartition 3, but is bridged by means ofconstruction elements 32 with aceiling 22 of the subway stop area. This results in a high degree of strength of thepartition wall 3, since pressure fluctuations are introduced into the floor of theplatform 2 as well as into theceiling 22 of the underground tunnel in the earth. The two-sided support at the top and at the bottom of thepartition 3 allows for a more delicate and lighter, thus more cost-effective construction. Theconstruction elements 32 are made of electrically conductive material and serve simultaneously for grounding purposes. - However, the
free space 30 above thepartition 3 is closed air-permeably. In the exemplary embodiment illustrated inFIG. 2 , the air-impermeable closure 4 consists ofgrille elements 40, which are arranged, for example, above theplatform doors 31, respectively. In the exemplary embodiment illustrated inFIG. 1 , thegrille element 40 consists of a plurality of baffle plates or profiledguide plates 41 arranged one above the other horizontally and which, in addition to the grille-like structure, guide the airflow permitted by thegrille element 40. In a further embodiment, the profiledguide plates 41 can be designed such that they can be adjusted via an actuator so that the grille element forms a closable ventilation grille. - In addition, above the
traffic area 10 in theceiling 22 of the underground tunnel, a smoke extraction system 5 is provided, with a vent orfan 51 and anair duct 52 for the subway system. In the event of any fire events, smoke gases can be withdrawn from theplatform area 20 via thegrille elements 40 or, as the case may be, theclosable ventilation grilles 44 in open position, and, of course, from thetraffic area 10. - Further, there is shown in
FIG. 2 thepartition 3 between therailroad platform 2 and theceiling 22, thefree space 30 above the partially raisedpartition 3 above theplatform doors 31 being provided withgrille elements 40 between the stiffeningconstruction elements 32. The area between thegrille elements 40 is provided with an air-impermeable closure element 43. When theplatform doors 31 are closed, air exchange L can thus only take place via thegrille elements 40 above theplatform doors 31. - By the deliberate provision of an air exchange L between the
traffic area 10 and theplatform area 20 above thepartition 3, it is ensured on the one hand that pressure differences can be compensated for quickly in these two areas and that, especially in the event of a fire, smoke extraction systems 5 arranged in thetraffic area 10 are also sufficient in order to extract any smoke gases which may occur in therailroad platform zone 20. These are sucked from theplatform area 20 by the air-permeable closure 4 above thepartition 3 into thetraffic area 10 and then to the smoke extraction system 5. - On the other hand, the closing of the open space above the
partition 3 by means ofgrille elements 40 orlockable ventilation grilles 44 permits a secure separation between theplatform area 20 and thetraffic area 10 so that no persons can climb over thepartition 3 from theplatform 2 into thetraffic area 10. No foreign bodies or only very small foreign bodies can enter thetraffic area 10 from theplatform area 20 through thegrille elements 40 orlockable ventilation grilles 44. A contamination of the track area and the associated risk of fire is thus largely avoided. In addition, the cleaning cost for the track area of the stops as well as the adjacent stretch of tunnels is reduced. -
