Plate, base plate are all as bridge deck, it is achieved double-layer traffic, for city multilane combined highway and metro and urban light rail, multilevel traffic construction
Thering is provided new structural shape, double-deck truss-type bridges is cheap than ever, and stress performance is superior., cost more nervous for land used is more
The Urban Bridge in the middle or small span in the city (30-60m) expensive, version is the most single is the most practical.
(V) double-layer traffic bridge is than conventional monolayer bridge, in same floor space, the traffic flow that can bear
Amount is 2 times of single layer bridge；If single layer bridge need to meet traffic flow identical with double-decker bridge, need to build another monolayer bridge, or
Person strengthens bridge deck width, its not only price high, and expend a large amount of land resource, therefore double-decker bridge is in traffic flow, takes up an area face
The aspects such as long-pending, construction cost are all than existing single layer bridge more advantage.
(VI) comparing built double-layer traffic bridge, the double-layer traffic concrete box girder of the design uses skew web plate form,
Abandon the most straight web box girder version, bridge subsurface width reduction, and well meet lower floor's communication function
Requirement, is effectively saved material, therefore use skew web plate not only meet double-layer traffic need, good looking appearance and effectively save
Resource and construction cost.
This utility model is extensively suitable for the little construction across footpath double-layer traffic bridge in city, is particularly suitable for multilane combined highway and metro
And urban light rail, multilevel traffic construction.
With embodiment, this utility model is described in further detail below in conjunction with the accompanying drawings.

Model ", " urban rail transit technology specification " " urban bridge design specification ", " highway reinforced concrete and prestressed concrete bridge
Contain design specification " and the correlation technique such as " Code for planning design of transport on urban road ", " load Standard in Urban Bridge Design " rule
Model, is designed the function aspects of double-layer traffic box beam.Then tie with concrete frame according to double-layer traffic concrete box girder
The similarity of structure, according to beam slab is theoretical and Frame Theory carries out structure design, in beam slab theory, using top board and base plate as
Plate, web considers as beam with the transverse stiffener replacing diaphragm plate, carries out the design of plate and beam；In Frame Theory, by abdomen
Plate considers as two parts, and wherein with the web of roof and floor junction certain altitude as Vierendeel girder, remaining web is as framework
Post, at bearing, transverse stiffener is as Vierendeel girder, carries out web and the design in bearing cross section.Finally its manufacturing process is divided into two
Individual construction section carries out cross construction making to double-layer traffic concrete box girder, as the first construction section bottom box beam base plate, web
Part, web middle and upper part, top board carry out flowing water work in an orderly manner as the second construction section part, the work such as concrete, reinforcing bar, template
Make, be finally completed the making of double-layer traffic concrete box girder.
Figure 29 is the fabrication processing block diagram of a kind of multifunctional concrete Box-girder Bridges for double-layer traffic.Its operation
Step is as follows:
A, material prepare；
Regular reinforcement bottom b, colligation box-shaped beam body, base plate, web；
