Abstract

The invention provides a 'building blocks-modularized' flyover with a steel structure. The flyover is designed into a structure module due to the performance of easiness of assembly and disassembly and the reproducibility of the steel structure, and the structures are fixed into a whole body by fixed pieces due to the building block type structure principle, so that crowded urban diverted traffics can be transformed, and stop-and-go traffic lights can be replaced. The basic structure of the flyover comprises a span flyover main body, an upper lane left-turning flyover body and a lower lane left-turning flyover body. The span flyover main body comprises a slope module, a transition module, a support module, a pressure dividing module and a sidewalk subsidiary flyover module. The upper lane left-turning flyover body comprises a joining module, an arc module, a support module and a pressure dividing module. The lower lane left-turning flyover body comprises a ramp module, an arc module, a support module and a pressure dividing module. According to the flyover system, the plane order of the urban traffic can be changed into a three-dimensional system, the stop-and-go moving mode can be changed into an ordered and smooth moving mode, the urban traffic jam can be overcome, and the traffic lights can be sifted out. The flyover with the steel structure belongs to renewable resources, is removable and renewable, and can not be evolved into municipal refuse. The flyover belongs to a building blocks-modularized structure, and is convenient to install and construct.

Description

The iron structure overpass bridge

Affiliated technical field

This invention is the iron structure overpass bridge of a kind of " building block moduleization ".

Background technology

At present, along with the rapid increase of the modernization development in city, particularly automobile, the traffic congestion phenomenon highlights day by day, is particularly metropolis such as Guangzhou, Beijing of example with China.Studying carefully its main cause is exactly the original incompatible present urban traffic demand of plane Order traffic rules, and the mode of loitering of traffic lights control is the main cause that the city blocks up.Therefore, exploitation multilevel traffic order is the basic scheme that solves urban traffic blocking.

Mostly existing overpass bridge is reinforced concrete structure, and the engineering time is long, complex structure, transform in the incompatibility urban centre, moreover it belongs to non-renewable resources, once discarded be exactly the most stubborn and stupid rubbish.

Summary of the invention

To above drawback, ad hocly counted this iron structure overpass bridge.Its basic mentality of designing is to utilize the property easy to assemble and the recyclability of iron structure; Be designed to construction module; Utilize building-block principle, be fixed into one, form the iron structure overpass bridge of stable strong with firmware; Be used to transform the intersection in city of blocking up, replace the traffic lights that loiter.

The solution of this invention is: the iron structure overpass bridge comprises strides the bridge main body, last trade left-hand rotation pontic, following trade left-hand rotation pontic.Stride the bridge main body and comprise the ramp module, excessive module, supporting module, division module, the secondary bridge module in sidewalk.Last trade left-hand rotation pontic comprises the linking module, arc module, supporting module, division module.Following trade left-hand rotation pontic comprises the ramp module, arc module, supporting module, division module.At first the bridge main body is striden in assembling in the intersection; On choosing, lay division module on the trade; Division module upper fixed supporting module; Reserve the walkway below the excessive module of supporting module top assembling, assembling ramp, two ends module, ramp module; The secondary bridge module in both sides assemblings sidewalk is striden the bridge main body like this and assemble and successfully told last trade and following trade.Refill and mix trade left-hand rotation pontic; In the fixing module that is connected of the lower slope section of the left turn lane of striding bridge main body one-way street left side, lay division module again, fixed support module above the division module, supporting module top assembling arc module makes trade left-hand rotation pontic stride across the subtend track and incorporates descending track into.Assemble trade left-hand rotation pontic down then; Striding beyond the bridge main body side; The left turn lane assembling ramp module in descending one way left side is laid division module, fixed support module above the division module again; Assembling arc module makes down trade left-hand rotation pontic stride across the subtend track and incorporates up-run lane into above the supporting module.All right-hand rotation ring roads all are layed in the outer rim of intersection system.This iron structure overpass bridge can make from the vehicle of different directions and accomplish to turn left to turn right in order and keep straight on.

This beneficial effect of the invention is: 1 changes the plane Order of urban traffic into three-dimensional order, changes the motor pattern that loiters the motor pattern of orderly smoothness into, has overcome urban traffic blocking, has eliminated traffic lights.2 iron structure overpass bridges belong to renewable resource, have mobility and recyclability, can not develop into municipal refuse.3 this overpass bridges belong to building block module formula structure and are convenient to installation.
