Abstract
The utility model relates to a urban bridge structure crossing highways or high grade channels. The urban bridge structure comprises a main bridge continuous box beam and is characterized in that the top of the main bridge continuous box beam extends to two sides to form cantilevers, the upper surface of the main bridge continuous box beam and the upper surfaces of the cantilevers form a motorway, steel cantilever beams are arranged below the cantilevers on two sides of the main bridge continuous box beam, the upper surfaces of the steel cantilever beams form a bicycle lane, and the steel cantilever beams are connected with joist steel fixed on the cantilevers via suspenders, inner sides of the steel cantilever beams are connected with the side portion of the main bridge continuous box beam via lugs. The bicycle lane is arranged below the cantilevers of the main bridge continuous box beam, the bicycle lane can be separated from the motorway, and the bicycle lane and the motorway are separately in profile design, so that the longitudinal slope of the motorway is enlarged and bridge length is reduced; main bridge deck width can be reduced and overall production cost of the main bridge can be reduced.
Description
Technical field
The utility model relates to a kind of bridge construction, the Urban Bridge structure of especially a kind of acrossing highway or high-grade waterway.
Background technology
In the construction of urban road network, the Large Span Bridges of acrossing highway or high-grade waterway occurs now and then, unavoidably.As everyone knows, under the bridge of this kind of Large Span Bridges, clear height and structure height are larger, and should not be greater than 2.5% according to " urban road highway route design standard " nonmotorized vehicle lane longitudinal gradient, as considered, people's nonmotorized vehicle lane and motorway pass a bridge jointly, now bridge length certainly will be longer, long in order to reduce bridge, reduce construction costs, be necessary to design a kind of rational structure and can meet needs that people's bicycle passes a bridge rationally to control bridge again long, and it is actually rare to meet at present the structural shape of these two kinds of requirements simultaneously.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and the Urban Bridge structure of a kind of acrossing highway or high-grade waterway is provided, and realizes people's nonmotorized vehicle lane and motorway and jointly passes a bridge, and rationally controls bridge long simultaneously.
The technical scheme providing according to the utility model, the Urban Bridge structure of a kind of acrossing highway or high-grade waterway, comprise main bridge continuous box girder, feature is: the top of this main bridge continuous box girder extends to form cantilever to both sides, and the upper surface of this main bridge continuous box girder and the upper surface of cantilever form motorway; Steel overarm is set below the cantilever of described main bridge continuous box girder both sides, and the upper surface of this steel overarm forms nonmotorized vehicle lane.
Described steel overarm is connected with the i iron being fixed on cantilever by suspension rod, and the inner side of steel overarm is connected with the sidepiece of main bridge continuous box girder by otic placode.
The width of described main bridge continuous box girder is 8.5m, and the width of both sides cantilever is respectively 4.5m, and the width of motorway is 17.5m; The width of steel overarm is 4.5m, and the height distance between steel overarm and cantilever is 2.5m.
The utility model is by being located at people's nonmotorized vehicle lane the form of structure under the cantilever of main bridge continuous box girder, on the one hand can people's nonmotorized vehicle lane is separated with runway, both carry out separately longitudinal section design, to reduce Ren Fei track absolute altitude, be convenient to Ren Fei track slope control≤2.5%, can make again motorway longitudinal gradient strengthen, reduce bridge long simultaneously; Can reduce on the other hand main bridge bridge deck width, reduce main bridge overall cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the lateral view of Fig. 1.
The specific embodiment
Below in conjunction with concrete accompanying drawing, the utility model is described in further detail.
As shown in Fig. 1～Fig. 2: as described in the Urban Bridge structure of acrossing highway or high-grade waterway comprise main bridge continuous box girder 1, cantilever 2, steel overarm 3, suspension rod 4, i iron 5, otic placode 6 etc.
As shown in Figure 1, the utility model comprises main bridge continuous box girder 1, and the top of this main bridge continuous box girder 1 extends to form cantilever 2 to both sides, and the upper surface of the upper surface of this main bridge continuous box girder 1 and cantilever 2 forms motorway; Steel overarm 3 is set below described main bridge continuous box girder 1 both sides cantilever 2, this steel overarm 3 is connected with the i iron 5 being fixed on cantilever 2 by suspension rod 4, the inner side of steel overarm 3 is connected with the sidepiece of main bridge continuous box girder 1 by otic placode 6, and the upper surface of this steel overarm 3 forms nonmotorized vehicle lane;
The width of described main bridge continuous box girder 1 is 8.5m, and the width of both sides cantilever 2 is respectively 4.5m, and the width of motorway is 17.5m; Cantilever 2 belows are nonmotorized vehicle lane, and the width of steel overarm 3 is 4.5m, and the height distance between steel overarm 3 and cantilever 2 is 2.5m.
Described steel overarm 3 adopts steel work effectively to alleviate dead load, improves the stressed of main bridge continuous box girder 1 both sides cantilever 2; Simultaneously steel outstanding 3 adopts otic placode 6 hinged with main bridge continuous box girder 1, can prevent from, because the cantilever 2 of main bridge continuous box girder 1 is different with the amount of deflection of steel overarm 3, producing excessive moment of flexure cause structural deterioration in the junction of steel overarm 3 and main bridge continuous box girder 1.
The utility model is by being located at people's nonmotorized vehicle lane the form of structure under the cantilever of main bridge continuous box girder, on the one hand can people's nonmotorized vehicle lane is separated with runway, both carry out separately longitudinal section design, to reduce Ren Fei track absolute altitude, be convenient to Ren Fei track slope control≤2.5%, can make again motorway longitudinal gradient strengthen, reduce bridge long simultaneously; Can reduce on the other hand main bridge bridge deck width, reduce main bridge overall cost.
