Abstract
The utility model discloses a longitudinal-cross beam combined bridge face structure which comprises a steel longitudinal beam and a steel cross beam. The steel longitudinal beam and the steel cross beam are arranged in a crossed mode, concrete bridge face plates are arranged on the steel longitudinal beam and the steel cross beam, shear nails are fixed on the upper surfaces of the steel longitudinal beam and the steel cross beam, the concrete bridge face plates are cast in the surfaces of the steel longitudinal beam and the steel cross beam in an in-place mode, and the shear nails penetrate through concrete of the concrete bridge face plates. The longitudinal-cross beam combined bridge face structure can improve rigidity of a bridge face, and simultaneously, is simple in stress, good in durability, and small in the maintenance amount, construction is easily achieved, and a reliable economic bridge face structural mode can be widely applied to the technical field of a steel structure bridge beam.
Description
Technical field
The utility model relates to the steel structure bridge technical field, particularly relates to a kind of in length and breadth beam in conjunction with bridge deck structure.
Background technology
At present build or the bridge floor form of built steel structure bridge as follows: (1) concrete road slag plate bridge deck structure.The set-up mode that the concrete road slag plate is fastened at Steel Bridge Deck has two kinds: a kind of be with concrete road slag plate freely-supported on gooseneck, another kind is that the concrete road slag plate is combined with the longitudinal and transverse beam of Steel Bridge Deck system, be not combined with main truss, bridge deck are little to the contribution of bridge floor rigidity in these two kinds of set-up modes, bearing is many, and particularly breaking joint later stage maintenance amount is large; (2) concrete slab integrated deck structure, integral rigidity is good, but concrete slab is combined with the steel bridge main chord, and stressed complexity is difficult for solving at the structure of main chord joint point; (3) steel integrated deck structure.The ballasted deck of several forms respectively has characteristics, in the railway steel bridge of different bridge-types application is arranged also at home and abroad.
The utility model content
The purpose of this utility model is in order to overcome the deficiency of above-mentioned background technology, provide a kind of in length and breadth beam in conjunction with bridge deck structure, be to improve bridge floor rigidity, simultaneously stressed simple, structure is easy to realize, good endurance, maintenance amount are little, the bridge deck structure form of reliable and economic.
A kind of in length and breadth beam that the utility model provides is in conjunction with bridge deck structure, comprise steel longeron and gooseneck arranged in a crossed manner, described steel longeron and gooseneck are provided with concrete slab, described steel longeron and gooseneck upper surface are fixed with WELDING STUDS, described concrete slab is cast-in-place in the surface of steel longeron and gooseneck, and described WELDING STUDS is goed deep in the concrete of concrete slab.
In technique scheme, described WELDING STUDS and steel longeron and gooseneck are welded and fixed.
In technique scheme, described concrete slab both sides are provided with the side bar that increases concrete slab both sides intensity.
Vertical gooseneck of the present utility model is in conjunction with bridge deck structure, has following beneficial effect: by WELDING STUDS is set, concrete slab and beam is jointly stressed has in length and breadth improved bridge stiffness, and simultaneously stressed simple, structure is easy to realization, good endurance, little, the reliable and economic of later stage maintenance amount.
Description of drawings
Fig. 1 be the utility model in length and breadth beam in conjunction with the overall structure schematic diagram of bridge deck structure;
Fig. 2 is the structure enlarged diagram of concrete slab among Fig. 1.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail, but this embodiment should not be construed as restriction of the present utility model.
Referring to Fig. 1 to Fig. 2, the utility model in length and breadth beam comprises steel longeron 1, gooseneck 2, concrete slab 3, WELDING STUDS 4 and sound barrier or railing 5 in conjunction with bridge deck structure.
Described steel longeron 1 and gooseneck 2 are arranged in a crossed manner, described WELDING STUDS 4 is fixed in the upper surface of steel longeron 1 and gooseneck 2, described concrete slab 3 is cast-in-place in the surface of steel longeron 1 and gooseneck 2, described WELDING STUDS 4 is goed deep in the concrete of concrete slab (3), by WELDING STUDS 4, concrete slab 3 is jointly stressed with steel longeron 1 and gooseneck 2, has improved bridge stiffness, in the present embodiment, described WELDING STUDS 4 is welded and fixed with steel longeron 1 and gooseneck 2; Described concrete slab 3 both sides are provided with the side bar 3.1 that increases concrete slab 3 both sides intensity, by the side bar 3.1 that concrete slab 3 is set, purpose is to solve concrete slab 3 edges name tensile stress problem bigger than normal, and corresponding with all fronts bridge floor layout, sound barrier or railing 5 can be set on the side bar 3.1.
Obviously, those skilled in the art can carry out various changes and modification to the utility model and not break away from spirit and scope of the present utility model.Like this, if of the present utility model these are revised and modification belongs within the scope of the utility model claim and equivalent technologies thereof, then the utility model also is intended to comprise these changes and modification interior.
The content that is not described in detail in this manual belongs to the known prior art of this area professional and technical personnel.
