Abstract
The utility model discloses a wave form steel abdomen slab bridge roof beam, including mixing the earth roof, concrete roof below interval is provided with polylith wave form steel web side by side, be provided with the concrete floor between two blocks of adjacent wave form steel webs, the position that wave form steel web is close to the bottom is provided with the flange plate that is used for holding the concrete floor tip, surface contact on concrete floor lower surface and the flange plate, concrete floor both ends side is connected with the wave form steel web that corresponds through the shear force nail respectively. The wave form steel abdomen slab bridge roof beam of this structure, not only the construction is simple and convenient, and the time limit for a project is short, moreover long service life.
Description
Technical field
The utility model relates to a kind of Wavelike steel webplate bridge.
Background technology
Large because of its integral rigidity across the scope of application that footpath below 250m is beam bridge, particularly concrete continuous beam, the advantage such as to drive a vehicle comfortable is widely used.But engineering practice in recent years find concrete beam across footpath more than 150m after, it is more outstanding that the span centre section of beam body continues the disease such as downwarp, cracking in webs problem, and many bridges just need when reaching far away design life to carry out strengthening reconstruction.It is comparatively large that its reason is to be increased to concrete beam deadweight to a certain degree across footpath, accounts for design internal force ratio excessive, concrete web shearing resistance, tensile strength relative deficiency.
In order to solve these diseases, a kind of new combining structure occurred in recent years and Wavelike steel webplate bridge.Wavelike steel webplate bridge refers to top, base plate adopts concrete, and web adopts the vertical superposed box bridge of waveform steel.Wavelike steel webplate instead of rear cabinet beam weight reduction, the minimizing of dead load internal force of concrete web, there will not be Web cracks.In addition due to the fold effect of Wavelike steel webplate, beam body bears moment of flexure by concrete top, base plate time curved, and Wavelike steel webplate bears shearing, and Each performs its own functions for roof and floor concrete, Wavelike steel webplate, take full advantage of the respective advantage of material, play the advantage of combining structure well.
, there is following shortcoming in existing Wavelike steel webplate bridge: 1) when concreting base plate, two ends are built for coming to nothing, and not only difficulty of construction is large, and concrete is difficult to reach sufficient compaction rate, and this has had a strong impact on the application life of bridge; 2) Wavelike steel webplate and the common connected mode of concrete floor are: by the part Transducers Embedded in Concrete of Wavelike steel webplate, and open hole and insert perforated rebar imbedding end, reinforce subsequently with steel mesh reinforcement to perforated rebar; First perforated rebar need be passed corresponding through hole by this mode one by one, is then woven into steel mesh reinforcement with many longitudinal reinforcements and transverse reinforcement and reinforces perforated rebar, and its difficulty of construction is large, long in time limit.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of easy construction, the duration short and Wavelike steel webplate bridge of long service life.
The utility model is solved the problem by following technological means: a kind of Wavelike steel webplate bridge, comprise mixed earth top board, below described concrete roof, spacing parallel arranging is provided with polylith Wavelike steel webplate, concrete floor is provided with between described adjacent two pieces of Wavelike steel webplates, described Wavelike steel webplate is provided with the frange plate for holding concrete floor end near the position of bottom, described concrete floor soffit contacts with frange plate upper surface, and side, concrete floor two ends connects with corresponding Wavelike steel webplate respectively by WELDING STUDS.
Further, described concrete floor two ends are provided with stiffener, and described stiffener is inserted in concrete floor.
Further, many baseplate reinforcing bars are provided with in described concrete floor.
Further, described frange plate upper surface is provided with projection.
The beneficial effects of the utility model: Wavelike steel webplate bridge of the present utility model, comprise mixed earth top board, below described concrete roof, spacing parallel arranging is provided with polylith Wavelike steel webplate, concrete floor is provided with between described adjacent two pieces of Wavelike steel webplates, described Wavelike steel webplate is provided with the frange plate for holding concrete floor end near the position of bottom, described concrete floor soffit contacts with frange plate upper surface, and side, concrete floor two ends connects with corresponding Wavelike steel webplate respectively by WELDING STUDS.The Wavelike steel webplate bridge of this structure, not only easy construction, the duration is short, and long service life.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is sectional view of the present utility model;
Fig. 3 is the structural representation that Wavelike steel webplate is connected with concrete floor.
Detailed description of the invention
Below with reference to accompanying drawing, the utility model is described in detail, as Figure 1-3: a kind of Wavelike steel webplate bridge, comprise mixed earth top board 1, below described concrete roof, spacing parallel arranging is provided with polylith Wavelike steel webplate 2, concrete floor 3 is provided with between described adjacent two pieces of Wavelike steel webplates, described Wavelike steel webplate is provided with the frange plate 4 for holding concrete floor end near the position of bottom, frange plate welds with Wavelike steel webplate, described concrete floor soffit contacts with frange plate upper surface, side, concrete floor two ends connects with corresponding Wavelike steel webplate respectively by WELDING STUDS 5, frange plate is also connected and fixed by WELDING STUDS and concrete floor.The Wavelike steel webplate bridge of this structure, on the one hand, the two ends of concrete floor are held respectively by the frange plate of correspondence, are not come to nothing to build when building, and difficulty of construction is low and fully ensure that concrete compactness, conscientiously ensure that the application life of bridge; On the other hand, concrete floor two ends are connected with Wavelike steel webplate side by WELDING STUDS after being held by frange plate again, and construction is simple, and the duration is short, and can conscientiously ensure to be connected and fixed effect.So this bridge not only easy construction, the duration is short, and long service life.
As the further improvement of technique scheme, described concrete floor two ends are provided with stiffener 6, and described stiffener is inserted in concrete floor.Stiffener and WELDING STUDS close contact, can prevent WELDING STUDS from getting loose, and ensure that the connection effect of concrete floor and Wavelike steel webplate.
As the further improvement of technique scheme, in described concrete floor, be provided with many baseplate reinforcing bars 7.The intensity of baseplate reinforcing bar energy Concrete Structure base plate, further increases application life and the endurance quality of bridge.
As the further improvement of technique scheme, described frange plate upper surface is provided with protruding 8.When concreting base plate, projection snaps in concrete, clamps after concrete setting, can ensure the steadiness that concrete floor is connected with Wavelike steel webplate further.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
