Further, described dissipative member at least arranges 2 groups, is provided with brace between cross bar adjacent in vertical plane, and described brace connects by bolt to be fixed with steel post.
Further, described steel post and cross bar are that steel plate cold bending is shaping, and cross section is " L " type, with elbow " L " type, " L " type with bending, the shape of described connector is mated with the shape of cross section of steel post.
Further, be welded with the junction plate fixed with cushion cap or pile foundation in the lower end of steel post, between junction plate and steel post, be fixed with stiffener.
Further, the cross sectional shape of described pier stud is rectangle or hourglass shape.
Further, described steel pier stud is fixed by coupling assembling and bent cap, the installing plate that described coupling assembling comprises and steel pier stud is fixed, be located at the slide plate in the groove of installing plate and be located at the elastic damping limiting component between slide plate and installing plate, described slide plate and bent cap are located by connector.
The invention has the beneficial effects as follows: each parts of bridge are prefabricated in factory to be completed, and on-site consolidation, accelerates speed of application, effectively ensures workmanship, and reduce the Coherent traffic noise to existing route; Adopt coupling assembling to connect pier stud and bent cap and utilize the flexibility of steel pier stud, bearing and part shrinkage joint can be removed, greatly improving the comfort level that road vehicles travels; Full-bridge adopt structure of steel product, greatly alleviate bridge deadweight, both facilitated on-site hoisting construction, reduce the construction volume of bridge pier, realize bridge construction up and down one lightness; Adopt connector multistage steel post to be connected into the steel post of desired height, the pier stud being connected to form desired height fast can be reached; The steel post deadweight of cold roll forming is little, rigidity is higher with deadweight, resistance to corrosion strong, can install rapidly in construction, material can be recycled, prefabricated accessory convenient; Connect the dissipative member of steel post, under geological process, absorb seismic wave energy, the brittle fracture of bridge pier main bearing member can be avoided.
Below in conjunction with accompanying drawing, the present invention is described in detail.
Accompanying drawing explanation
Fig. 1 is the structural representation of the steel bridge in the present invention;
Fig. 2 is the schematic cross-section of cross bar and steel post in Fig. 1;
Fig. 3 is the structural representation of coupling assembling.
In the accompanying drawings: 1 is steel post, 2 is cross bars, and 3 is connectors, and 4 is braces, and 5 is junction plates, and 6 is stiffeners, and 7 is cushion caps, and 8 is bent caps, and 9 is coupling assemblings, and 9-1 is installing plate, and 9-2 is slide plate, and 9-3 is elastic damping limiting component.
Detailed description of the invention
Referring to accompanying drawing 1, assembly type steel one bridge, comprise the steel pier stud be fixed in cushion cap or pile foundation, the bent cap 8 being located at steel pier stud top and the girder be fixed on bent cap 8, its key is: described steel pillarwork comprises 4 or 5 steel posts 1 and connects the dissipative member of each steel post 1, and every root steel post 1 connects shaping by multistage steel post by connector 3.Adopt connector 3 multistage steel post to be connected into the steel post 1 of desired height, the object of the pier stud being connected to form desired height fast can be reached.
Referring to accompanying drawing 3, steel pier stud is fixed by coupling assembling 9 and bent cap 8, the installing plate 9-1 that the structure of coupling assembling 9 comprises and steel pier stud is fixed, be located at the slide plate 9-2 in the groove of installing plate 9-1 and be located at the elastic damping limiting component 9-3 between slide plate 9-2 and installing plate 9-1, described slide plate 9-2 is connected with bent cap 8.When the girder be connected with bent cap 8 stretches, slide in the groove first in installing plate 9-1.When stroke exceedes the slippage stroke of slide plate 9-2, the top of steel pier stud has the flexibility of certain amplitude, can adapt to girder and to stretch the change of amplitude, play the effect of partial rubber bearing.For reducing the frictional force that slide plate 9-2 slides in installing plate 9-1 groove, polyfluortetraethylene plate can be fixed in a groove, fix corrosion resistant plate in the bottom surface of slide plate 9-2.
In the structure of steel pier stud, steel post 1 forms pillarwork by dissipative member, dissipative member arranges at least 2 groups in the short transverse of steel post 1, described dissipative member comprises the cross bar 2 being connected to form cluster type structure at grade with adjacent steel column 1, is provided with horizontal shear support between cross bar 2.Dissipative member connects steel post, under outside geological process, because the intensity of Crossing brace is little compared with steel post, under being subject to the load based on shearing, prior to steel post surrender, can absorb the object that energy reaches protection steel post.
Cross bar 2 is fixedly connected with adjacent steel column 1 by bolt connection, and horizontal shear support connects by bolt and is connected with steel post 1 or cross bar 2.Be fixed with cast steel connector or forged steel connector at the two ends of cross bar 2, cross bar 2 is fixedly connected with adjacent steel column 1 by bolt connection by cast steel connector or forged steel connector.Be provided with brace 4 between cross bar 2 adjacent in vertical plane, described brace 4 is fixedly connected with steel post 1 by bolt connection.Be welded with junction plate 5 in the lower end of steel post 1, between junction plate 5 and steel post 1, be fixed with stiffener 6.When pier stud has 4 steel posts 1, its cross sectional shape is rectangle; When there being 5, its cross sectional shape is hourglass shape.
Referring to accompanying drawing 2, steel post 1 and cross bar 2 are that steel plate cold bending is shaping, and cross section is " L " type, with elbow " L " type, " L " type with bending.Steel plate, through clod wash, by changing its shape, improves its anti-folding, anti-flexing, antitorque, anti-pressure ability, and its materials to compare the section bar such as rectangle steel or pipe few, and need not to gain in strength by cement concrete again.
Assembly type Integral steel bridge of the present invention is for Urban Bridge and Expressway Extension Project, steel lattice column is utilized to replace traditional concrete pier, steel truss bent cap replaces concrete bent cap, realizes light-duty, the bridge design theory of pier beam integration and the method for rapid construction.Can be used for newly reconstructing newly-built, the reconstruction of bridge of speedway, Class I highway, significantly can improve the construction speed of bridge, shorten construction period, more can reduce the various impacts that urban interchange causes because the construction period is long, with quick service in society, create larger social benefit.
