Abstract
The utility model relates to the field of railway bridges, in particular to a composite bridge for a railway. The composite bridge is formed by combining a channel girder and two steel box arch ribs through hanging rods, the two ends of the composite bridge are supported through cushion cap piers, the two steel box arch ribs are distributed on the two sides of the channel girder respectively, the arch feet of the steel box arch ribs are integrally connected with the channel girder through a reinforced concrete arch base and the cushion cap piers, the upper ends of the hanging rods are fixedly arranged in the steel box arch ribs through anchor heads, and the lower ends of the hanging rods are fixedly arranged in the channel girder through anchor heads. Under the condition that the bridge meets a low-attitude bridge road surface, the structural strength requirements of the bridge meet standards, the structure is reasonable, and cost is low.
Description
Technical field
The utility model relates to the railroad bridge class, is specifically related to a kind of combined bridge for railway.
Background technology
Along with railway technology growing today, the area that railway traffic covers is more and more wider, in urban planning, sometimes also needs to enter the traffic that railway equipment slows down growing tension.Yet the city complex structure is disorderly huge, build rail facility and can be subject to various restrictions, the facilities such as existing high-rise building and overline bridge, if the method high cost of rebuilding after the employing complete removal, general small and medium cities can't be born, and the construction period is long, and construction period can make troubles to townsfolk's trip.Adopt the mode of putting up a bridge to build railway and can save great amount of cost, and reduce the impact on existing utility, but the oscillation intensity during the railroad bridge operation requires bridge to have sturdy bridge pier structure disperses the power of unloading, and this exerts a certain influence to the existing facility under bridge.Therefore under should guaranteeing that low clearance guarantees the minimized situation of city existing utility impact again, bridge also will have the operation of can bearing the structural strength of vibrating while rolling track is arranged, and existing railroad bridge technology all can't perfection meet above-mentioned technical requirements restriction.
The utility model content
The purpose of this utility model is according to above-mentioned the deficiencies in the prior art, and a kind of combined bridge for railway is provided, and by the combination of trough girder and steel box arch rib, when meeting the bridge requirement of strength, effectively reduces constructionheightofbridge.
The utility model purpose realizes being completed by following technical scheme:
A kind of combined bridge for railway, described combined bridge two ends are supported by the cushion cap bridge pier, it is characterized in that described combined bridge is mainly combined by trough girder and steel box arch rib, described steel box arch rib is positioned at described trough girder side, the arch springing of described steel box arch rib is connected with described cushion cap bridge pier and described trough girder by the steel concrete abut, between described steel box arch rib and described trough girder, is provided with some groups of suspension rods.
Between the arch springing of described steel box arch rib both sides and described steel concrete abut, by screw-thread steel, be fixedly connected with, the steel box arch rib inside that is positioned at described arch springing place is provided with stiffening rib.
Lay respectively between the described steel box arch rib of described trough girder both sides and steel box arch rib and be connected with the stull of horizontal in-line truss.
Described combined bridge is equipped with track on road surface.
Every group of described suspension rod is vertically two hanging rod structures, and described pair of hanging rod structure distributed and form along the bridge direction by two different suspension rods of cross-sectional sizes.
The utility model has the advantages that: be applicable to the limited operating mode of building height of bridge, structure economics is reasonable, technology is reliable, can effectively reduce building height, and effectively guarantees building integral rigidity.
The accompanying drawing explanation
Fig. 1 is the utility model agent structure schematic diagram;
Fig. 2 is the top view of Fig. 1;
Fig. 3 is the schematic cross-section of arch springing in Fig. 1;
Fig. 4 is the lateral view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, by embodiment, the utility model feature and other correlated characteristic are described in further detail, so that technician's of the same trade understanding:
As Figure 1-4, in figure, the 1-10 mark is respectively: steel box arch rib 1, steel concrete abut 2, cushion cap bridge pier 3, trough girder 4, suspension rod 5, truss 6, stiffening rib 7, anchor head 8, the track of rolling 9, arch springing 10, top board 11, base plate 12 and web 13 are arranged.
Embodiment: as Figure 1-4, the present embodiment relates to a kind of combined bridge for railway, this combined bridge is combined by trough girder 4 and steel box arch rib 1 and suspension rod 5, the combined bridge two ends are supported by cushion cap bridge pier 3, described trough girder 4 both sides are respectively arranged with steel box arch rib 1, arch springing 10 places of steel box arch rib 1 are connected with cushion cap bridge pier 3 and trough girder 4 by steel concrete abut 2, the upper end of suspension rod 5 is fixed in steel box arch rib 1 by anchor head 8, and the lower end of suspension rod 5 is fixed in trough girder 4 by anchor head 8.
Vertically two hanging rod structures in the present embodiment, have been adopted, to prevent the covibration of suspension rod, suspension rod 5 is mutually vertical with trough girder 4 planes, on the girder of trough girder 4 both sides, be symmetrically arranged with respectively seven groups of vertically two hanging rod structures, every group of two suspension rods are distributed and form along the bridge direction by two different suspension rods 5 in cross section.The parallel wire unit that the parallel wire unit that vertically two hanging rod structures in the present embodiment are twisted into by 37 7 high-strength underrelaxation zinc-coated wires respectively and 55 7 high-strength underrelaxation zinc-coated wires twist into forms, due to the different reason of radical, the section area of two bundle parallel wire units is also different, adjacent and parallel being lifted between trough girder 4 and steel box arch rib 1 of two above-mentioned bundle steel tendons.
Between the arch springing 10 of steel box arch rib 1 both sides and steel concrete abut 2, by the 32mm screw-thread steel, be fixedly connected with, steel box arch rib 1 inner top 11, base plate 12 and the web 13 at arch springing place all is equipped with the stability that stiffening rib 7 is connected to improve steel box arch rib 1 bottom.Between steel box arch rib 1, be fixed with three road yi word pattern truss 6, truss 6 is as the transversely strengthening fixed structure between two steel box arch ribs 1.
On the road surface that the base plate of the present embodiment combined bridge trough girder 4 forms, can be equipped with and roll track 10 and carry out railway transportation.
Due to the structure reason of trough girder 4, effectively reduce the antenna height of this enforcement combined bridge, 3 both sides that are arranged on pontic of cushion cap bridge pier, reached and minimized the impact of existing facility under bridge.The lifting that the fixed connection structure that steel box arch rib 1 is reached by steel concrete abut 2 and cushion cap bridge pier 3 and 5 pairs of trough girders 4 of suspension rod apply has guaranteed the requirement of strength of bridge.
