Abstract
The invention relates to a main structure of a steel structure viaduct with stayed suspension cables. The main structure is especially suitable to enlarge the traffic volumes of roads and railways. By adopting the main structure, road construction can be implemented under the premises of not adding occupied roads and not interrupting the original traffics, thus fundamentally solving the problem of jams caused by few roads but more vehicles. The main structure is characterized in that the upper ends of suspension cables are fixedly connected at one sides of upright columns and bearing cross beams are suspended at the lower ends of the suspension cables; the span of the bearing cross beams is from 20 meters to 90 meters; trusses have oblong sections and the span of the trusses is from 8 meters to 36 meters; a two-layer steel structure viaduct can be constructed by a superposition method under the premise of constructing a single-layer steel structure viaduct with stayed suspension cables; a reticulated shell structure is fixedly connected at the top ends of the upright columns; and a waterproof electric hot plate is paved on the periphery of the reticulated shell structure.
Description
One, technical field
The present invention relates to a kind of steel structure and tiltedly draw suspension cable viaduct main structure, be applicable to the traffic volume that enlarges urban road and speedway and railway especially.
Two, background technology
Existing city vehicle sharply increases, and road construction receives restrictions such as planning, soil, removal can't satisfy current needs, and vehicle blocks up and has a strong impact on city function and social economic order.The various vehicles while mixed runnings that carrying capacity and speed difference are bigger, it is existing frequently with traffic accident to block up.When meeting with ice and snow sleet weather, road is very easily lost current function, and is prone to multiple traffic accident.The collinear mixed running of passenger and freight train, the late rate of passenger train is high.As build the steel concrete viaduct, and certainly will interrupt original passing through, form bigger pressure for roads of other current difficulties, very easily bring out the paralysis of urban transit system integral body.
Steel structure bridge, factory building, building, stadiums etc. are more both at home and abroad at present sees that what wherein load was bigger is steel structure bridge.The viaduct is steel concrete, steel structure viaduct as yet not the parent see that also be not seen in the relevant report of medium, online is zero to the search of steel structure viaduct.(Chemical Industry Press publishes main reference of the present invention " structural steelwork knowledge figure separates with the construction essence "; No. 13, young Hunan, Dongcheng District, Beijing street); (publishing house of University Of Chongqing publishes " steel work principle and design "; Phone: 023-65102378), and just the technical problem in the invention and reasonability, safety etc. are consulted and have been seeked advice from relevant expert.
Three, summary of the invention
The purpose of this invention is to provide a kind of steel structure and tiltedly draw suspension cable viaduct main structure; Can do not increase road take up an area of with the prerequisite of not interrupting original traffic under implement road construction; Fundamentally thoroughly solve the many problems of blocking up of the few car in road; Thereby greatly improve the traffic volume of original road, and make it possess round-the-clock current function.
The upper end of suspension cable is fastened on a side of column, its lower end suspension load-bearing crossbeam, and the span of load-bearing crossbeam is 20 meters to 90 meters.
The cross section of truss is a rectangle, and the span of truss is 8 meters to 36 meters.
Can draw tiltedly that stack is built into clad steel structure viaduct under the prerequisite of suspension cable viaduct building individual layer steel structure.
The column top is fixedly connected with latticed shell structure
The outer rim of latticed shell structure is equipped with the waterproof electric hot plate.
Benefit of the present invention: the one, road construction need not be taken over the land for use and remove, and has made full use of the space of original road; The 2nd, can not interrupt original traffic during construction, the duration is shorter relatively; The 3rd, both be applicable to urban traffic, also be applicable to speedway and railway; The 4th, can effectively improve the traffic volume of original road; The 5th, loaded vehicle is sailed with quick dolly branch at a slow speed, and passenger traffic and goods train branch are sailed, and has ensured that public transit vehicle and passenger train are current smooth and easy, and has reduced accident rate; The 6th, installed the latticed shell structure of anti-ice and snow sleet additional, have round-the-clock current function; The 7th, the dismounting recyclable utilization in back.

The numbering annotation of Fig. 1 to Fig. 4: (1) column, (2) load-bearing crossbeam, (3) truss, (4) suspension cable, (5) road surface; (6) latticed shell structure, (7) fixed mount, (8) waterproof electric hot plate, the fire-resistant duroplasts of (9) modification; (10) purlin support bar, (11) insulating board, (12) purlin, (13) purlin connecting rod.
Five, the specific embodiment
With the urban road is example:
The first step: please possess the relevant expert of one-level qualification or authoritative architectural design institutes, technical feasibility of the present invention is proved.Confirm to be suitable for the kind, specification of steel etc., to calculate the accurate data of various loads, and present the conclusion and recommendations to decision-making level.
Second step: on the basis that application feasibility of the present invention is further proved, take into full account the needs of future transportation development, the layout of buildings of integrated planning steel structure viaduct.
The 3rd step: the exploration road, and coordinate relevant departments and carry out preparation of construction.
The 4th step: follow procedure confirms to possess the one-level qualification and construction team and management company that practical experience is arranged.
The 5th step: strict monitoring steel product quality, must there be quality assurance single during purchase, must detect behind the arrival and check and accept.
Surplus with steel structure project construction implementation step.
