Abstract
The present invention relates to a kind of highway and railway clad steel-mixed bondbeam.In main truss structure, lower chord and highway crossbeam, highway longeron, railway beam welding or bolt are integrally; Main truss upper chord lower end is welded with main truss structure lower end or bolt is connected, and upper end is connected with highway crossbeam, highway longitudinal beam welding or bolt; Be connected by the Shear connection key arranged at the rod member top board be in direct contact with it with highway concrete bridge deck, railway concrete bridge deck (concrete trough girder) at highway longeron, highway crossbeam, upper chord, railway node crossbeam; railway concrete bridge deck adopt steel-mixed bondbeam; make the formation of the highway and railway clad steel of formation-mixed bondbeam overall; participation structure is totally stressed; reduce rolled steel dosage; reduce on-the-spot steel work maintenance work; improve bridge construction durability; alleviate noise pollution, be conducive to environmental protection.
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.Under normal circumstances, the combined bridge engineering scale of construction is large, is all positioned at great rivers even offshore area, passes through developed area, and its economy, to be subject to the degree of social concern too to the influence degree of environment high.Steel truss girder bridge is arranged because being convenient to double deck, and be the conventional type that combined bridge adopts, its traditional railway deck all adopts the open bridge floors or orthotropic steel bridge deck with 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 extensive Problems 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, and lower floor is railway deck, in main truss structure, and Xia Yu highway crossbeam, highway longeron, railway beam welding or bolt are integrally; Main truss upper chord lower end is welded with main truss structure lower end or bolt is connected, and upper end is connected with highway crossbeam, highway longitudinal beam welding or bolt; Be arranged in the highway longeron on upper strata, highway crossbeam, upper chord be connected by Shear connection key with highway concrete bridge deck, described Shear connection key is arranged on highway longeron, highway crossbeam, upper chord top board; The railway node crossbeam being arranged in lower floor is connected by Shear connection key with railway concrete bridge deck, and described Shear connection key is arranged on the top board of railway node crossbeam; Railway concrete bridge deck adopt steel-mixed bondbeam;
Described concrete trough girder cross section is made up of twice straight wall and base plate, and longitudinal section forms entirety by the cast-in-place joint concrete of concrete trough girder and railway crossbeam place.
Highway of the present invention, railway concrete bridge deck and concrete trough girder and highway in length and breadth beam, railway crossbeam and upper chord are combined that to form overall participation structure totally stressed.Railway deck system cancels longeron and the internode crossbeam of traditional railway bridge deck, only arranges node crossbeam, and railway deck and concrete trough girder are combined with railway node crossbeam top by Shear connection key that to form overall participation structure totally stressed.Highway bondbeam forms the double-deck bondbeam in steel purlin together with railway bondbeam.
Adopt the present invention; solve 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, reduces rolled steel dosage; reduce girder steel maintenance work; improve bridge construction durability, alleviate noise pollution, be conducive to environmental protection.

Detailed description of the invention
With reference to Fig. 1, main truss structure 1 top-bottom chord of the present invention and highway crossbeam 2, highway longeron 3, iron node road crossbeam 4 weld or bolt integrally, main truss upper chord 8 lower end is welded with main truss structure 1 lower end or bolt is connected, and upper end is welded with highway crossbeam 2, highway longeron 3 or bolt is connected.Be arranged in the highway longeron 3 on upper strata, highway crossbeam 2, upper chord 8 be connected by Shear connection key 7 with highway concrete bridge deck 5.Described Shear connection key is arranged on highway longeron, highway crossbeam, upper chord top board.The railway node crossbeam 4 being arranged in lower floor is connected by Shear connection key 7 with railway concrete bridge deck 6, and described Shear connection key is arranged on the top board of railway node crossbeam 4.
Described concrete trough girder cross section is made up of twice straight wall and base plate, and longitudinal section forms entirety by the cast-in-place joint concrete of concrete trough girder and railway crossbeam place.
Longitudinal section adopts concrete trough girder to substitute longeron and railway bridge panel, is connected to form steel-mixed bondbeam between concrete trough girder and railway node crossbeam by arranging Shear connection key.
Beam, railway crossbeam and upper chord are combined that to form overall 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 trough girder to replace railway longeron and railway bridge panel, to be combined with railway node crossbeam top by Shear connection key that to form overall participation structure totally stressed.Highway bondbeam forms the double-deck bondbeam in steel purlin together with railway bondbeam.
