Abstract
The invention relates to a road and railway double-layer steel-concrete combined beam. On main truss structures, lower booms, road crossbeams, road longitudinal beams, and railway crossbeams are welded or bolted together; the lower ends of the upper booms of the main trusses are welded or bolted with the lower ends of the main truss structures; the upper ends of the upper booms are welded or bolted with the road crossbeams and the road longitudinal beams; the road longitudinal beams, the road crossbeams, the upper booms and a railway node crossbeam are connected with road concrete bridge panels and railway concrete bridge panels (concrete beam channel) by shear force connecting keys of rod piece top plates in direct contact with the same; the railway concrete bridge panel adopts a steel-concrete combined beam, so the formed road and railway steel-concrete combined beam forms a whole and participates in the integral stressing, the usage of rolled steel is reduced, the curing work of the steel structure on site is reduced, the durability of the bridge structure is improved, the noise pollution is reduced and the environment is favorably protected.
Description
Technical field
The present invention relates to a kind of highway and railway clad steel-mixed bondbeam.
Background technology
Along with socioeconomic development, road-cum-rail bridge more and more embodies its great function, is subject to the favor of socio-economic development and transport development.Generally, the combined bridge engineering scale of construction is large, is all positioned at even offshore area of great rivers, passes through developed area, and its economy, that the influence degree of environment is subject to the degree of social concern is too high.Steel truss girder bridge is arranged because being convenient to double deck, is the conventional pattern that combined bridge adopts, and its traditional railway deck all adopts has open bridge floors or the orthotropic steel bridge deck of beam in length and breadth.It is large with steel material, and operation maintenance workload is heavy, produces the environmental issues such as rubbish excretion, noise pollution during operation simultaneously.For highway bridge, it is also the problem extensively existing that asphalt paving of steel bridge layer damages.In order to improve the deficiency of above-mentioned bridge floor form, the double-deck composite beam bridge of invention highway and railway dual-purpose truss steel.
Summary of the invention
The object of the invention is for above-mentioned present situation, aim to provide the highway and railway clad steel-mixed bondbeam of a kind of reasonable stress, simple structure, cost economic, constructability.
The implementation of object of the present invention is, highway and railway clad steel-mixed bondbeam, and upper strata is highway bridge, lower floor is railway deck, in main truss structure, Xia Yu highway crossbeam, highway longeron, it is whole that railway beam welding or bolt become; Main truss upper chord lower end is connected with the welding of main truss structure lower end or bolt, and upper end is connected with highway crossbeam, highway longitudinal beam welding or bolt; At highway longeron, highway crossbeam, upper chord, railway node crossbeam, be connected with the Shear connection key that railway concrete bridge deck are arranged by the rod member top board being in direct contact with it, railway concrete bridge deck adopt steel-mixed bondbeam;
Described concrete grooved beam cross section is comprised of twice straight wall and base plate, and longitudinal section consists of whole the cast-in-place joint concrete of pregroove marks beam and railway crossbeam place.
Highway of the present invention, railway concrete bridge deck are that beam, railway crossbeam and upper chord are totally stressed in conjunction with forming whole participation structure in length and breadth for concrete grooved Liang Yu highway.Railway deck system cancels longeron and the internode crossbeam of traditional railway bridge deck, and node crossbeam is only set, and railway deck is that concrete grooved beam is totally stressed in conjunction with forming whole participation structure by Shear connection key and railway node crossbeam top.Highway bondbeam forms the double-deck bondbeam in steel purlin together with railway bondbeam.
Adopt the present invention; solved the flimsy problem of highway steel bridge floor asphalt mixture surfacing; simultaneously; because railway deck adopts steel-mixed bondbeam, trough girder participation structure is stressed, has reduced rolled steel dosage; reduced girder steel maintenance work; improve bridge construction durability, alleviated noise pollution, be conducive to environmental protection.
Accompanying drawing explanation
Fig. 1 is main truss Nodes main beam section structure chart;
Fig. 2 is main truss internode place girder main truss profile;
Fig. 3 is concrete grooved beam and railway node crossbeam annexation figure.
The specific embodiment
With reference to Fig. 1, main truss structure 1 top-bottom chord of the present invention and highway crossbeam 2, highway longeron 3,4 welding of iron node road crossbeam or bolt become whole, main truss upper chord 8 lower ends are connected with main truss structure 1 lower end welding or bolt, upper end is connected with highway crossbeam 2,3 welding of highway longeron or bolt, at highway longeron 3, highway crossbeam 2, upper chord 8, railway node crossbeam 4, is connected with the Shear connection key 7 that highway concrete bridge deck 5, railway concrete bridge deck 6 are arranged by the rod member top board being in direct contact with it.
Described concrete grooved beam cross section is comprised of twice straight wall and base plate, and longitudinal section consists of whole the cast-in-place joint concrete of pregroove marks beam and railway crossbeam place.
Longitudinally adopt concrete grooved beam to substitute longeron and railway bridge panel, between concrete grooved beam and railway node crossbeam, by Shear connection key is set, be connected to form steel-mixed bondbeam.
Beam, railway crossbeam and upper chord are combined that to form whole participation structure totally stressed in length and breadth by shear connector and highway for highway of the present invention, railway concrete bridge deck.Railway deck system cancels longeron and the internode crossbeam of traditional railway bridge deck, node crossbeam is only set, utilize concrete grooved beam to replace railway longeron and railway bridge panel, totally stressed in conjunction with forming whole participation structure by Shear connection key and railway node crossbeam top.Highway bondbeam forms the double-deck bondbeam in steel purlin together with railway bondbeam.
Claims (2)
1. highway and railway clad steel-mixed bondbeam, upper strata is highway bridge, lower floor is railway deck, it is characterized in that in main truss structure, Xia Yu highway crossbeam, highway longeron, it is whole that railway beam welding or bolt become; Main truss upper chord lower end is connected with the welding of main truss structure lower end or bolt, and upper end is connected with highway crossbeam, highway longitudinal beam welding or bolt; At highway longeron, highway crossbeam, upper chord, railway node crossbeam, be connected with the Shear connection key that railway concrete bridge deck are arranged by the rod member top board being in direct contact with it, railway concrete bridge deck adopt steel-mixed bondbeam;
Described concrete grooved beam cross section is comprised of twice straight wall and base plate, longitudinally the cast-in-place joint concrete of pregroove marks beam and railway crossbeam place, consists of whole.
2. highway and railway clad steel according to claim 1-mixed bondbeam, is characterized in that concrete grooved beam and railway node crossbeam are connected to form bondbeam by Shear connection key.
