According to the invention, the evacuation maintenance platform is set on the horizontal beam; evacuation channel and maintenance channel structures are adopted; the evacuation channel and the maintenance channel are not influenced by each other; and the platform provided herein has the advantages of simple structure, convenient use and high safety.
Description
Technical field
The present invention relates to technical field of bridge construction, evacuates maintenance in particular to a kind of armful of rail rail traffic bridge flat
Platform.
Background technology
Magnetic levitation track traffic and cross-saddle single-track traffic using unique " embracing rail " method of operation, meet vehicle gauge
Small bore single line box beam is " embracing rail " most economical beam type of formula track traffic.Program beam structure is travelled by vehicle rail
Road, two-wire location take the juxtaposed mode of two panels single line box beam to process, and domestic built magnetic is floated and cross-saddle single-track traffic track
Liang Jun adopts this beam type.Fig. 1 is Shanghai high speed Maglev track girder sectional view, and Fig. 2 is Chongqing City's cross-saddle single-track traffic
Track girder sectional view, Fig. 3 are certain medium-and low-speed maglev traffic experiment line track girder sectional views.Because of vehicle " embracing rail " operation, small bore
On single line box girder bridge, space is less, and using limited space, box beam top surface can only meet track and arrange needs, power rail, cable
When can be hung on outward box beam side and bottom surface, circuit maintenance repair maintenance and vehicle generation accident needed for passenger's emergency evacuation
Passage cannot arrange.
First straddle-type monorail that Shanghai high speed Maglev, domestic medium-and low-speed maglev test wire and Chongqing are built is handed over
No. 2 line elevated bridges of logical line are not provided with evacuating inspection platform, such as the Human Evacuation during Emergencies such as fire difficulty, bridge
Upper line upkeep is also more inconvenient.For meeting circuit regular maintenance and rescue run needs, Chongqing City is building Article 2
During cross-saddle single-track traffic trajectory No. 3 lines of traffic, completed along circuit by individually setting up girder steel between two trajectory beams
Cable laying, the maintenance of grid coverage steel plate formation thereon and rescue run passage.The processing mode solves daily line upkeep
And the access issues of passenger's emergency evacuation, but still suffer from some defects：Fire escape top surface is far below vehicle floor face, personnel
Evacuate extremely inconvenient；Railing is not provided with around fire escape, and swarm and jostlement event easily occurs when the amount of evacuating an endless flow of people is big；Maintenance is flat
Platform is integrated with rescue run passage, and the cable placed on inspection platform ruptures in passenger evacuation or leaks electricity can be made to passenger
Into personal injury.
The content of the invention
Present invention aim to solve the deficiency of above-mentioned background technology, there is provided a kind of rail rail traffic bridge of embracing is dredged
Scattered inspection platform, fire escape is arranged on above access path, while meeting the in emergency circumstances evacuation of personnel and daily right
The maintenance of circuit.
The technical scheme is that：A kind of rail rail traffic bridge of embracing evacuates inspection platform, including two juxtaposed lists
The crossbeam of longitudinally spaced setting between line box beam, it is characterised in that also including the longitudinal access path being arranged on above crossbeam with
And the fire escape above access path, on the crossbeam, two ends are provided with the column for supporting fire escape.
Preferably, the access path includes access path base plate and is disposed longitudinally on below same heel post, connects adjacent
The lower longeron of column, the access path base plate are longitudinally laid under both sides on longeron.
Further, the fire escape includes fire escape base plate and is disposed longitudinally on above same heel post, connects phase
The upper longeron of adjacent column, the fire escape base plate are longitudinally laid on both sides on longeron.
Further, on the fire escape, between longeron, lateral separation is provided with cross rib plate, and the access path also includes
Arrange, be connected the web member of lower longeron from the outside of upper longeron with cross rib plate corresponding position straight down.
Further, the access path web member is provided with the guardrail of longitudinally connected many web members, and multilamellar guardrail is vertical
Direction interval setting.
Further, the access path web member is provided with cable bearer, and the cable bearer includes vertically being fixed on
Longitudinal carrier and the multilamellar horizontal support being connected on longitudinal carrier on web member.
Further, the fire escape fire escape plate upper surface is highly flushed in or is got on the bus less than two single line box beams
Height of floor from rail top.
Preferably, the fire escape both lateral sides are provided with railing, and the longitudinally spaced setting of the railing, the evacuation are led to
The interval of road both lateral sides railing is interlaced.
Further, the fire escape upper railing is included below the main railing of interval setting and main railing along longitudinal both sides
Secondary railing, the main railing, secondary railing is many cross bars and Duo Gen montants connect the quadra to be formed.
Further, the handrail that manually can be opened is provided with above the fire escape railing, the handrail is fixed for one end
On railing, one end be removably attachable to the suspension chain on longitudinally adjacent railing.
In the present invention, will crossbeam be set between two single line box beams, two box beams are connected by crossbeam, increases the horizontal firm of entirety
Degree.Evacuate inspection platform to be arranged on crossbeam, using double-decker, used as fire escape, lower floor is dredged as access path on upper strata
Scattered passage is used for the evacuation of in emergency circumstances personnel, and access path is used for daily line upkeep, and the two is using being independent of each other.
Advantages of the present invention is：
1. fire escape both sides arrange railing, and pedestrian is protected, it is to avoid during evacuation, artificial abortion is excessive crowded causes personnel
Fall, increase safety.
2. fire escape either flush in or slightly below two single line box beams on vehicle floor, be easy to passenger to be directly entered thin
Scattered passage, in case of emergency increased the speed of evacuating personnel.
3. fire escape, access path are attached to form overall structure by column, web member, upper longeron, lower longeron, jail
Solidity is high, and bearing capacity is strong.
4. multilayer cable holder is provided with the outside of access path, be easy to the placement of cable, and cable is isolated with fire escape
Open, it is to avoid during evacuating personnel, contact cable causes danger.
