Abstract
The utility model provides a pedestrian bridge stayed-cable bridge tower. The pedestrian bridge stayed-cable bridge tower is characterized in that the stayed-cable bridge tower comprises a bridge tower body arranged symmetrically; the upper end of the bridge tower body is provided with anchor rods used for fixing guy cables; and the lower end of the bridge body is connected and provided with an over beam. The structure of the pedestrian bridge stayed-cable bridge tower is designed rationally; the construction difficulty is low; little time is needed for construction; the appearance of the bridge tower is attractive; and the cost is low. The pedestrian bridge stayed-cable bridge tower can meet the requirement of construction and development of very safe and firm pedestrian bridges with increasingly high requirement for spans, and the requirement for the optimum ratio of performance to price for construction of the pedestrian bridge. In addition, the aesthetics is improved; and the detrimental effects on road traffic during the construction of the pedestrian bridge are reduced.
Description
Technical field
The utility model belongs to the particularly accessory technical field of overpass of bridge construction structure, is specifically related to a kind of novel structure, pedestrian overcrossing bridge Tower Column of A Cable Stayed Bridge sturdy and durable and handsome in appearance.
Background technology
Increase day by day along with urbanization construction and road traffic pressure, increasing city and area are selected to build on vehicle pass-through flow road, build overpass to alleviate traffic pressure, avoid the contradiction between pedestrian and the motor vehicle, improve the traffic safety degree.The overpass of various moulding has also beautified urban construction in addition, becomes a place or zonal sign.At present China builds and the overline bridge in building all adopts the pontic of steel framework or reinforced concrete structure, its construction period is longer, making and installation cost are higher, application life is very limited, this becomes the deadly defect that the city overline bridge is built, therefore a lot of places have to adopt cost higher, administer and maintain comparatively that the underground passage of difficulty replaces overpass, and underground passage can be given moving to change and bringing bigger influence and defective of city and road pipe network.Say objectively, the traffic guiding effect of People's Bank of China's overpass is stronger than underground passage, construction period is shorter relatively, cost is lower, can in the shortest time, mix the contradiction of going by transport solution node people car, by adopting the pedestrian overcrossing of new structure and material, can be good at solving the problems that present overline bridge construction exists.
Fibre reinforced composites (FRP) are to use increasingly extensive a kind of novel structural meterials in recent years in civil engineering.It has high-strength, lightweight, remarkable advantage such as corrosion-resistant, at the reinforcement and strengthening of structure, go along with sb. to guard him aspect such as anticorrosion and obtained good application.Along with the superior function of FRP material is approved by engineering circle gradually, external many engineerings begin it is applied in the newly-built bridge, or even in the Longspan Bridge.Since the seventies in last century, the FRP material just begins to attempt using in bridge engineering.Britain, the U.S. and Israel use this new material at first as the main member in building structure and the bridge construction, and what adopted mostly at that time is GFRP (glass fibre reinforced composion, i.e. glass fiber reinforced plastic).
Since the light weight of fibre reinforced composites, and pedestrian overcrossing does not need bigger load-bearing, and therefore structure and the requirement of strength to Tower Column of A Cable Stayed Bridge needn't be too high, and should meet easy construction, sound construction and lightweight advantage.
The utility model content
The purpose of this utility model provides the pedestrian overcrossing bridge Tower Column of A Cable Stayed Bridge fast, handsome in appearance between a kind of reasonable in design, difficulty of construction hour, that the cost cost is low, it can adapt to the pedestrian overcrossing construction that firmly performance is high of different spans requirement, safety and the needs of development, satisfy the optimality price ratio that pedestrian overcrossing is built, and the raising aesthetic measure reduces the adverse effect of pedestrian overcrossing construction to road traffic.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of pedestrian overcrossing Tower Column of A Cable Stayed Bridge is characterized in that described Tower Column of A Cable Stayed Bridge has symmetrically arranged bridge tower main body, and the bridge main body upper end is provided for the anchor pole of stay guy, and the connection of bridge main body lower end is provided with overarm.
Concretely, described bridge tower main body is two Gen Lita that are symmetrical set, and is provided with the drag-line that connects two Gen Lita between the upper end of described two Gen Lita, connects the overarm that location usefulness is set between the lower end of described two upright towers.
Described bridge tower main body is the arched girder structure, and the top arcuate of bridge tower main body is connected and fixed, and the lower end of bridge tower main body is provided with the overarm that connects arched girder.
One side of described bridge tower main body is provided for the anchor pole of fixed bridge rope, and opposite side is provided with two dorsal funciculus.
Described bridge tower main body is the rectangular beam structure that steel I-beam or steel concrete are constructed.
This pedestrian overcrossing Tower Column of A Cable Stayed Bridge can be crossed on the both sides that People's Bank of China passes a bridge, can be used in single pylon cable-stayed bridge, also can satisfy the use of double pylon cable stayed bridge, the bridge tower main body both can be two Gen Lita that are separately positioned on People's Bank of China gap bridge both sides, also can be the arched girder structure that two ends lay respectively at People's Bank of China gap bridge both sides.The bridge tower main body upper end of two upright tower structures preferably is provided with the drag-line that connects two Gen Lita, to strengthen the stability between two Gen Lita.And the upper end arch of arched girder structure links together, and forms an integral body, Stability Analysis of Structures.Be that the two upright tower structures or the bridge tower main body of arched girder structure all need be provided with the connection overarm in its lower end, the upper end is provided for the anchor pole of fixed bridge rope.Since install and use in, the fixedly connected bridge rope of side needs of Tower Column of A Cable Stayed Bridge upper end, the suffered pulling force of Tower Column of A Cable Stayed Bridge for this pulling force of balance, just can be provided with dorsal funciculus at the opposite side of Tower Column of A Cable Stayed Bridge all from a direction so.
The beneficial effects of the utility model are, fast, handsome in appearance between the reasonable in design of this pedestrian overcrossing Tower Column of A Cable Stayed Bridge, difficulty of construction hour, the cost cost is low, span be can adapt to and the pedestrian overcrossing construction increasing, that the firm performance of safety is high and the needs of development required, satisfy the optimality price ratio that pedestrian overcrossing is built, and the raising aesthetic measure, when reducing the pedestrian overcrossing construction to the adverse effect of road traffic.
