Abstract
The invention discloses a bridge deck structure with longitudinal beams and transverse beams combined. The bridge deck structure comprises the longitudinal steel beams and the transverse steel beams, wherein the longitudinal steel beams and the transverse steel beams are arranged in a crossed mode. A concrete bridge deck slab is arranged on the longitudinal steel beams and the transverse steel beams, shear nails are fixed to the upper surfaces of the longitudinal steel beams and the surfaces of the transverse steel beams, the concrete bridge deck slab is cast on the surfaces of the longitudinal steel beams and the surfaces of the transverse steel beams in place, and the shear nails penetrate deep into concrete of the concrete bridge deck slab. The rigidity of the bridge deck can be improved, and meanwhile the bridge deck structure is simple in stress, easy to obtain, good in durability, small in maintenance amount, reliable, economical and capable of being widely applied in the technical field of steel structure bridges.
Description
Technical field
The present invention relates to steel structure bridge technical field, particularly relate to one 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 concrete road slag plate is fastened at Steel Bridge Deck has two kinds: one be by concrete road slag plate freely-supported on gooseneck, another kind is that concrete road slag plate is combined with the longitudinal and transverse beam of Steel Bridge Deck system, be not combined with main truss, in these two kinds of set-up modes, bridge deck are little to the contribution of bridge floor rigidity, 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 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 feature, also has application at home and abroad in the railway steel bridge of different bridge-types.
Summary of the invention
The object of the invention is the deficiency in order to overcome above-mentioned background technology, provide one in length and breadth beam in conjunction with bridge deck structure, be to improve bridge floor rigidity, simultaneously stressed simple, structure is easy to that realization, good endurance, maintenance amount are little, the bridge deck structure form of reliable and economic.
One provided by the invention in length and breadth beam 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 invention is in conjunction with bridge deck structure, there is following beneficial effect: by WELDING STUDS is set, concrete slab and in length and breadth beam are jointly stressed, have improved bridge stiffness, and simultaneously stressed simple, structure is easy to that realization, good endurance, later stage maintenance amount are little, reliable and economic.
Brief description of the drawings
Fig. 1 be the present invention 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 in Fig. 1.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in further detail, but this embodiment should not be construed as limitation of the present invention.
Referring to Fig. 1 to Fig. 2, the present invention 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 on 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 of concrete slab 3 is set, object is to solve concrete slab 3 edge name tensile stress problem bigger than normal, and corresponding with all fronts bridge floor layout, sound barrier or railing 5 can be set on side bar 3.1.
Obviously, those skilled in the art can carry out various changes and modification and not depart from the spirit and scope of the present invention the present invention.Like this, if these amendments of the present invention and within modification belongs to the scope of the claims in the present invention and equivalent technologies thereof, the present invention is also intended to comprise these changes and modification interior.
The content not being described in detail in this manual belongs to the known prior art of professional and technical personnel in the field.
