Description
Technical field
The present invention relates to a kind of combined structure type overpass bridge.
Background technology
In road traffic automobile use amount in service, day by day increase, and existing road means of transportation do not catch up with development and make that some is main, the smooth vehicle congestion of Zhi Gandao intersection passing is very serious.Road traffic now adopts single overpass bridge, bridge or tunnel to solve traffic jam issue, and vehicle-pedestrian conflict, traffic lights is set and waits for restricted driving, greatly reduces road traffic traffic efficiency, even brings many potential safety hazards; Or adopt pedestrian overcrossing or People's Bank of China's tube, and to pedestrian, going across the road and bring very big inconvenience, in urban highway traffic, motor vehicles safety hazard and the main status of people in road traffic of causing to pedestrian that block up is more and more subject to social concerns and attention.
Summary of the invention
Technical problem solved by the invention is to provide a kind of combined structure type overpass bridge, to solve the problem proposing in above-mentioned background technology.
Technical problem solved by the invention realizes by the following technical solutions:
Combined structure type overpass bridge, comprises straight-through track and the sidewalk of the south-north direction of first floor, the turning roadway of the second layer, east-west straight-through track and the sidewalk of the 3rd layer; Describedly lead to turning roadway layer and lead to east-west straight-through track and sidewalk layer is equipped with the track, slope communicating with each other; The turning roadway central authorities of the described second layer are provided with the annular district of detouring that turns.
The straight-through track of the south-north direction of described first floor, the second layer and the 3rd layer and sidewalk, turning roadway and east-west straight-through track and sidewalk are by steel structure framework, road surfacing material (sheet metal and other auxiliary material), the auxiliary compositions such as material (channel-section steel, angle steel, sheet metal and other auxiliary material), outer ornament materials that fix.
Described steel structure framework is comprised of load-bearing double-screw bolt, skeleton component and other auxiliary material.
Described load-bearing double-screw bolt is made by round steel, and the epimere of described load-bearing double-screw bolt is provided with screw thread, for being connected and fixed, hypomere is provided with corrosion-resistant coating, the quantity of described load-bearing double-screw bolt is a plurality of, between load-bearing double-screw bolt, is led admittedly each other by channel-section steel and slab, makes bed rearrangement overpass bridge form an integral body.
Described skeleton component by various section bars such as channel-section steel, bar steel, angle steel by its residing position and function and the Steel material framework that the different workpieces of processing is formed by fixedly connecting via standard components such as screw, nuts.
Described auxiliary material comprises finger screw, nut and securing member.
Current principle: it is directly current that the straight-through vehicle of south-north direction is incorporated to straight-through track in advance, the vehicle that needs to turn (no matter left and right) is incorporated to turning roadway in advance, walks to the second layer detour by ramp, and pedestrian is directly current by sidewalk; East-west straight-through vehicle is incorporated in advance straight-through track and walks to the 3rd layer of direct passing through by slope, and the vehicle that need turn walks to the second layer by ramp and detours, and pedestrian walks to the 3rd layer by ramp and directly passes through.
Beneficial effect
Compared with prior art, cost of the present invention is low, on-site construction time is short, floor space is little and because there is no tediously long access bridge, transit route is short and sweet, and it is current more convenient to make, and to remove convenient simultaneously.

The specific embodiment
Below in conjunction with the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
Embodiment
As Figure 1-3, combined structure type overpass bridge, comprises straight-through track 1 and the sidewalk 2 of the south-north direction of first floor, east-west straight-through track 4 and sidewalk 5 that the turning roadway of the second layer is 3, the three layers; Describedly lead to turning roadway 3 and lead to east-west straight-through track 4 and sidewalk 5 is equipped with the track, slope 6 communicating with each other; The turning roadway central authorities of the described second layer are provided with the annular district 12 of detouring that turns, and its installation steps are as follows:
1, as Figure 4-Figure 6, according to the scale of institute's bridge and geographical conditions, determine quantity and the position of load-bearing double-screw bolt 7, around each place-centric, dig the hole (concrete size, the degree of depth are depending on geographical conditions) of a certain limit and certain depth, with pile driver, its hypomere (processing through corrosion protection) is thrown into undergroundly, then in dug hole, watered concrete.If residing geographical conditions are bad, also can take other reinforcement measure.(distributing position of double-screw bolt should stagger track and sidewalk, be typically chosen in the isolated area on track and sidewalk; Piling and pouring construction generally should be constructed for the previous period formal, solid to guarantee concrete; Construction should be carried out at night, not affect traffic.If planning is in order, general all pre-buried should completing in one night of double-screw bolt).
2, as shown in Figure 7, skeleton component is installed: after the concrete of pre-buried load-bearing double-screw bolt 7 is solid, with channel-section steel 8 and slab (for the road surface of driving a vehicle), each load-bearing double-screw bolt 7 is led mutually solid, then above skeleton component 9 being arranged on, 7 of skeleton component 9 and load-bearing double-screw bolts are affixed with screw, nut 10 and other clamping washer 11, (it is solid that every one deck basal plane of three layers all should have channel-section steel 8 or slab to lead).
3, bridge floor and side dividing plate are installed: the steel plate that preprocessing is good is arranged on corresponding position by corresponding size and requirement, uses equally screw, nut and other securing member affixed.
