Abstract
The present invention relates to rail transit and tunnels, in particular to a through type spine girder used for a rail transit station. The spine girder is composed of a girder 14 and end cross girders 11,12, the lower edges of both sides of the girder is provided with a cantalever which is a track bed slab 13, and the end cross girders are positioned at the ends of the track bed slab. The present invention has the advantage that a track girder is combined with a platform girder, no gap needs to be arranged between the track girder and the track girder, so no leakage water is produced to affect the functions of an equipment management cabinet under a platform, the longitudinal altitude difference caused by construction errors, structural deformation or uneven settlement is avoided, thus reducing potential safety hazards, and meanwhile, because the heights of buildings are low, the height of a railway station is reduced, thus reducing the lifting altitude of passengers.
Description
Technical field
The present invention relates to track traffic and tunnel-like, be specifically related to be used for the bottom bearing box beam of rail traffic station.
Background technology
The rail beam of domestic existing track traffic island station, platform beam generally adopt the separate type beam, and the pattern of employing mainly is the combination of box-girder, plate-girder, tee girder, trough girder etc., as shown in Figure 1 and Figure 2.
Rail beam adopts the station of deck type force structures such as box-girder, plate-girder, tee girder, as shown in Figure 1, building height is higher, cause the higher and also corresponding raising of comprehensive cost of passenger's hoisting depth, consider that simultaneously platform beam and rail beam beam face generally all have the 1.5m left and right sides discrepancy in elevation, therefore platform beam deck-molding needs very high or the higher independent bridge pier of platform beam employing, causes material usage big, and the pier stud quantity more station hall layer that seems in bottom is messy simultaneously.
The beam at above-mentioned separate type station if two (many) abdomens spine beams that rail beam, platform beam are designed to unite two into one satisfy the station view, safety, people-oriented, comprehensive cost is low and function on composite request.
Summary of the invention
The objective of the invention is according to above-mentioned the deficiencies in the prior art part, a kind of bottom bearing box beam that is used for rail traffic station is provided, this spine beam unites two into one rail beam and platform beam, and make rail beam be positioned at the lower edge of platform beam, with satisfy the station view, safety, people-oriented, comprehensive cost is low and function on composite request.
The object of the invention realizes being finished by following technical scheme:
A kind of bottom bearing box beam that is used for rail traffic station is characterized in that this spine beam is made of the girder and the end floor beam of marginal zone cantilever under the both sides, and described cantilever is a bed board, and end floor beam is positioned at the end of bed board.
Described girder is the case beam.
Described road bed board (also can establish girder), girder and end floor beam are structure as a whole.
Advantage of the present invention is, rail beam and platform beam unite two into one, and the two need not to establish seam, can not produce percolating water and influences under the platform equipment management with the function in room; Avoided reducing potential safety hazard because construction error, malformation or differential settlement bring vertical discrepancy in elevation; Because building height is low, reduce the station height simultaneously, reduced passenger's hoisting depth, demonstrated fully the design concept that people-oriented.

The specific embodiment
Feature of the present invention and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that technician's of the same trade understanding:
Shown in Fig. 1-5, label 1-14 represents respectively: platform T beam 1, vehicle 2, track box beam 3, bridge pier 4, platform beam pad stone 5, track trough girder 6, platform case beam 7, platform floor 8, station spine beam 9, safety door 10, end floor beam 11, end floor beam 12, road bed board 13, girder 14.
Embodiment:
Shown in Fig. 3-5, the station bottom bearing box beam comprises rail beam and platform beam, and what the rail beam of present embodiment adopted is bed board 13, also can establish beam certainly, and what the platform beam adopted is girder 14, and end floor beam 11,12 is positioned at the end of bed board 13.Girder 14 is a case beam form, girder 14 lower edges with cantilever be bed board 13, end floor beam 12 is positioned at the end of bed board 13.Road bed board 13, girder 14 and end floor beam 11,12 are structure as a whole.
Present embodiment is as a kind of lower support type structure spine beam, and vehicle directly travels on the outrigger base, and base plate thickness is less.The track box beam or the T beam of the general 30m span of its building height ratio reduce 1.5m approximately.The variation of striding the footpath does not simultaneously influence the rail level absolute altitude at station, and this is remarkable to reducing station and interval building height effect.
The station spine beam is formed an integral body to platform beam and rail beam unification, be convenient to standardization, modularized design, the drawing workload is saved half, and substructure also need not be considered the influence that the two difference in height causes simultaneously.The platform girder end face that structure stress needs is as platform floor, and its inner space can be satisfied pipeline requirement is set, so sectional space utilization rate height.The external type grace of the beam of station spine beam own has reduced separate type platform beam, the messy sense of rail beam bottom vision.Owing to made full use of the platform beam as girder, saved material usage, the technical-economic index of itself is lower than separate type platform beam, rail beam structure, spine beam has characteristics such as building height is low, sectional space utilization rate height simultaneously, can reduce the substructure engineering quantity, reduce the station volume, and corresponding reduction interval structure height, so cost is lower.Because building height is lower, reduced station, interval and device height, reduce energy consumption during the operation, require consistently with country reduces energy waste, reduce the maintenance cost of long-term operation simultaneously.
Be embodied everywhere in current society that people-oriented, today that energy loss and urban environment, view are paid much attention to, the station channel beam is compared with other station girder construction form has very big competitive advantage undoubtedly, be a kind of outstanding, the novel station girder construction pattern that is suitable for track traffic, it will have broad application prospects.
Studies have shown that the foregoing description spine beam arch value of creeping is significantly smaller than traditional beam type, this popularization that VIADUCTS IN URBAN RAIL TRANSIT is laid the solid concrete roabed technology highly significant.
The construction of the foregoing description is various informative, can select cast-in-place or the prefabricated and cast-in-place job practices that combines according to field condition, so that construction is reduced to minimum degree to the influence of urban traffic and environment.
