Abstract
The utility model discloses a support rail continuous beam in a double track railway, which is applicable to multistory elevated stations or other places with limited structural height of support rail beams. The continuous beam consists of prestressed concrete side stringers (10), prestressed concrete secondary stringers (11), reinforced concrete cross beams (12) and a reinforced concrete bridge deck (13), wherein two prestressed concrete side stringers (10) are arranged outside a side limit of a railway; two prestressed concrete secondary stringers (11) are arranged at intervals along the direction of a cross bridge between the two prestressed concrete side stringers (10); and the reinforced concrete cross beams (12) are arranged at intervals along the direction of a straight bridge below the reinforced concrete bridge deck (13) and intersect with the prestressed concrete side stringers (10) and the prestressed concrete secondary stringers (11) to form a groove-shaped lattice structure.
Description
Technical field
The utility model relates to railway support rail beam, particularly is applicable to the interior support rail continuous beam of double track railway at large-scale synthesis station.
Background technology
Develop rapidly along with China Express Railway and urban public transport construction, some super-huge stations such as Beijing Station, Guangzhou Railway Station, station, Wuhan, station, Chengdu etc., according to relevant city integrated traffic programme, it will be the comprehensive transportation hub that integrates subway, ground public transport hinge, speed rail passage and inter-city passenger rail etc., realize passenger's seamless connection transfer, thereby need build up multi-functional, the comprehensive station of three-dimensional.As passenger station, Chengdu east, design scale is 14 26 lines, is followed successively by No. 7 lines of subway, No. 2 lines of subway, subterranean layer, station layer from top to bottom, the super-huge station of multilayer of wait floor and roof system formation.
General overhead railway bridge adopts the support rail beam of deck type, this beam is directly held track, vehicle under track, but for the super-huge station of above-mentioned multilayer, usually because building to the requirement of space headway (lower floor, station layer and the interlayer passenger that waits change into adjustable height) frugally, the needed structure height of support rail beam that adopts deck type can't be provided, thereby must adopt beam types such as lower support type steel truss girder, trough girder.And for the lower support type beam of medium and small span in the station, a kind of cost of specialized designs is low, noise is little, be easy to that the support rail continuous beam is more reasonably to select in the prestressed concrete of maintenance.
The utility model content
Technical problem to be solved in the utility model provides a kind of interior support rail continuous beam of double track railway that is applicable to multilayer overhead station or the height-limited system of other support rail girder constructions.
The technical scheme that its technical problem that solves the utility model adopts is: support rail continuous beam in the double track railway of the present utility model, it is characterized in that: this continuous beam is by prestressed concrete limit longeron, prestressed concrete time longeron, steel concrete crossbeam and reinforced concrete bridge deck plate constitute, two prestressed concrete limit longerons are arranged on outside the gauge of railway side, along direction across bridge two prestressed concretes time longeron is set at interval therebetween, the steel concrete crossbeam under the reinforced concrete bridge deck plate along along bridge to being provided with at interval, and with prestressed concrete limit longeron, prestressed concrete time longeron intersects to form the flute profile grid structures.
The beneficial effects of the utility model are, make full use of the discrepancy in elevation between platform floor and the rail level, farthest reduced the structure height of support rail beam, from the rail level to the soffit, can save height 2.0m, thereby saved the height of station from underground departures layer to station layer and marquis's car layer, can reduce the construction investment at large-scale synthesis station significantly, and have the advantage that cost is low, noise is little, be easy to maintenance.
Description of drawings
This manual comprises following three width of cloth accompanying drawings:
Fig. 1 is the vertical view of support rail continuous beam in the utility model double track railway;
Fig. 2 is the sectional view along A-A line among Fig. 1;
Fig. 3 is the sectional view along B-B line among Fig. 1.
Toponym shown in the figure and corresponding mark: prestressed concrete limit longeron 10, prestressed concrete time longeron 11, steel concrete crossbeam 12, reinforced concrete bridge deck plate 13.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
See figures.1.and.2, support rail continuous beam in the utility model double track railway is characterized in that: this continuous beam is made of prestressed concrete limit longeron 10, prestressed concrete time longeron 11, steel concrete crossbeam 12 and reinforced concrete bridge deck plate 13.With reference to Fig. 2, two prestressed concrete limit longerons 10 are arranged on outside the gauge of railway side, along direction across bridge two prestressed concretes time longeron 11 are set at interval therebetween.With reference to Fig. 2 and Fig. 3, steel concrete crossbeam 12 is provided with to the interval along suitable bridge under reinforced concrete bridge deck plate 13, and intersects to form the flute profile grid structures with prestressed concrete limit longeron 10, prestressed concrete time longeron 11.
Prestressed concrete time longeron 11 the stress condition that has improved prestressed concrete limit longeron 10 is set, promptly form the main force structure of four longerons by two prestressed concrete limit longerons 10 and two prestressed concretes time longeron 11, train loads etc. are transmitted to prestressed concrete limit longeron 10, prestressed concrete time longeron 11 by steel concrete crossbeam 12, are transmitted to lower support structures such as bridge pier by prestressed concrete limit longeron 10, prestressed concrete time longeron 11 again.With reference to Fig. 2, the bottom surface of described prestressed concrete time longeron 11, the bottom surface of steel concrete crossbeam 12 flush with the bottom surface of prestressed concrete limit longeron 10.With reference to Fig. 1, described steel concrete crossbeam 12 and prestressed concrete limit longeron 10, prestressed concrete time longeron 11 are vertical.
The about 10.3m of center to center distance between the high about 3.0m of prestressed concrete limit longeron 10, two prestressed concrete limit longerons 10, the spacing between each prestressed concrete limit longeron 10, the concrete edge longeron 10 is about 3.5m; Prestressed concrete time longeron 11, steel concrete crossbeam 12 high about 1.15m, each steel concrete crossbeam 12 spacings 2.5～3.5m; The cast-in-place gap between steel concrete crossbeam 12 and prestressed concrete limit longeron 10, prestressed concrete time longeron 11 of reinforced concrete bridge deck plate 13, thickness is 25～30cm.
Some principles of support rail continuous beam in the above the utility model double track railway that just explains through diagrams, be not be the utility model to be confined to shown in and in described concrete structure and the scope of application, so every the corresponding modify and equivalent that might be utilized all belongs to the claim that the utility model is applied for.
