Description
Technical Field
The utility model relates to a track traffic technical field especially relates to be applied to overpass's arch gate-type mound.
Background
In recent years, with the rapid development of economy in China, more and more urban expressways and more overpasses are developed, the lower part of the overpass is excessively complicated by bridge piers, vehicles and pedestrians under the overpass are inconvenient to pass, and the roads under the overpass are narrower due to the excessive gate-type piers, so that congestion is caused, and great waste is caused to road resources and land resources under the overpass.
A large number of gate-type piers are arranged under the overpass, the gate-type piers occupy a large amount of road resources, if a large gate-type pier can be built to place a plurality of upper structures on the same gate-type pier, the occupation of land can be avoided from being influenced by the excessive gate-type piers, meanwhile, the overpass can be more concise, and the jam caused by the complexity of roads under the overpass can be avoided. However, the span of the conventional portal pier is generally not more than 20m, and the problem of different elevations of the upper structures of a plurality of bridges cannot be solved.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the defects existing in the prior art and providing an arch gate pier applied to an overpass.
In order to realize the purpose, the utility model adopts the following technical scheme: be applied to arched door type pier of overpass, including the pier, the top fixedly connected with straining beam of pier, the top fixedly connected with arch rib of straining beam, the top fixedly connected with steel stand of straining beam, the top fixedly connected with bent cap of steel stand, the top of bent cap is provided with the expressway main road, the top of straining beam just is located the equal fixedly connected with jib in both sides about the steel stand, the top and the arch rib fixed connection of jib, the top of straining beam just is located and is provided with the ramp between jib and the arch rib.
As a further description of the above technical solution:
the arch rib is arc-shaped, and the steel upright post, the cover beam, the main expressway, the suspender and the interchange ramp are all positioned below the arch rib.
As a further description of the above technical solution:
and a guy cable is arranged in the tie beam.
The utility model discloses following beneficial effect has:
1. the utility model discloses, the span can reach more than fifty meters, has improved the horizontal leap ability of bridge by a wide margin, has expanded the application scope of bridge.
2. The utility model discloses, the superstructure of many bridges can be erect simultaneously to arch gate-type mound to can satisfy the different problem of different bridge superstructure elevation.
3. The utility model discloses, avoided too much gate-type mound under the overpass to cause land resource road waste, avoided too complicated traffic road under the overpass simultaneously.
4. The utility model discloses, can set up the balanced hunch foot thrust of cable inside the tie beam, make the pier basis not have transverse thrust, can satisfy various geological conditions, extended the application scope of bridge.
Drawings
Fig. 1 is a front view of the arched gate pier applied to the overpass of the present invention.
Wherein, 1, bridge piers; 2. tying a beam; 3. an arch rib; 4. a boom; 5. a steel upright post; 6. a capping beam; 7. a main road of the express way; 8. and (5) overpass ramps.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, the present invention provides an embodiment: an arched portal pier applied to an overpass comprises a pier 1, a tie beam 2 is fixedly connected to the top of the pier 1, a guy cable (not shown in the figure) is arranged inside the tie beam 2 and used for balancing arch foot thrust by arranging the guy cable, an arch rib 3 is fixedly connected to the top of the tie beam 2, a steel upright post 5 is fixedly connected to the top of the tie beam 2, a cover beam 6 is fixedly connected to the top of the steel upright post 5, beam bodies with different elevations adjusted by arranging the steel upright post 5 and the cover beam 6 are erected on the same portal pier, the portal pier has high practical value, a main expressway path 7 is arranged at the top of the cover beam 6, suspenders 4 are fixedly connected to the top of the tie beam 2 and positioned on the left side and the right side of the steel upright post 5, the rigidity of the arched portal pier is greatly improved by arranging an arch rib 3 and the suspenders 4, the transverse capacity of the bridge is greatly improved, and the top end of the suspenders 4 is fixedly connected with the arch rib 3, and an interchange ramp 8 is arranged at the top of the tie beam 2 and between the suspender 4 and the arch rib 3, the arch rib 3 is arc-shaped, the steel upright post 5, the cover beam 6, the main expressway road 7, the suspender 4 and the interchange ramp 8 are all positioned below the arch rib 3, and the tie beam 2 and the interchange ramp 8 are poured together to improve ramp traffic height limitation.
The working principle is as follows: the rigidity of the arched door-type pier is greatly improved by arranging the arch ribs 3 and the hanging rods 4, the transverse crossing capacity of the bridge is greatly improved, the beam bodies with different elevations are adjusted by arranging the steel stand columns 5 and the cover beams 6 and erected on the same door-type pier, and the balance of arch springing thrust is realized by arranging the stay ropes.
