Abstract
The utility model belongs to bridge construction technical field, relates to a kind of steel bow bridge ruggedized construction particularly.Steel bow bridge ruggedized construction is reinforcing cage, concrete, the wedge shape bridge pier that reserved steel bar head group becomes.Build wedge shape Reinforced Concrete Bridge Piles at steel Gong Qiao two ends and reinforce steel bow bridge, wedge shape Reinforced Concrete Bridge Piles internal construction is the reinforcing cage of reinforcement welding, outside concreting, profile is wedge shape, top reserved steel bar head, when installing steel bow bridge, first by wedge shape bridge pier press-in ground, the steel bar end that body of a bridge bottom and bridge pier are reserved is welded together, thus plays the effect of reinforcing steel bow bridge.
Description
Technical field
The utility model belongs to bridge construction technical field, relates to a kind of steel bow bridge ruggedized construction particularly.
Background technology
Steel bow bridge is that a kind of new city hands over universal bridge, can solving urban traffic blocking effectively.Main employing welding for steel structure forms, steel bow bridge is built on level land, body of a bridge likeness in form " bow " shape, primary load bearing structure is the vertical bridge column of bridge two ends welding, when bridge floor pressurized, bridge column bears pressure at right angle and tangential force, because bridge column is vertical structure, bear the limited in one's ability of tangential force, bear tangential force for a long time and steel can be made to bend bridge longevity reduction.
Utility model content
The utility model just in order to solve steel bow bridge bear for a long time tangential force cause steel bend bridge construction destroy problem, utilize simple structural strengthening steel bend bridge.
The utility model adopts following technical method to realize: build wedge shape Reinforced Concrete Bridge Piles at steel Gong Qiao two ends and reinforce steel bow bridge, wedge shape Reinforced Concrete Bridge Piles internal construction is the reinforcing cage of reinforcement welding, outside concreting, profile is wedge shape, top reserved steel bar head, when installing steel bow bridge, first by wedge shape bridge pier press-in ground, the steel bar end that body of a bridge bottom and bridge pier are reserved is welded together, thus plays the effect of reinforcing steel bow bridge.
Described Reinforced Concrete Bridge Piles, its inside is bar construction, longitudinally has several thicker reinforcing bar, laterally fixes with several thinner reinforcement welding, forms reinforcing cage, outside concreting, forms wedge shape bridge pier.
Described Reinforced Concrete Bridge Piles, reserves steel bar end on bridge pier top during concreting, install steel bow bridge time and bridge floor steel beam column be welded to connect.
Described Reinforced Concrete Bridge Piles, its cross section is the inverted trapezoidal that upper base is very little, utilizes static pressure to install bridge pier is pressed into ground during installation.
The beneficial effects of the utility model are: can offset the tangential force produced because of bridge floor compressive deformation, make steel bend bridge construction more firm, and extend steel bow bridge application life, and bridge pier structure is simple, it is convenient to install.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of steel bow bridge ruggedized construction.
Fig. 2 is the front view of steel bow bridge bridge pier.
Fig. 3 is the left view of steel bow bridge bridge pier.
Fig. 4 is the schematic diagram of steel bow bridge bridge pier internal construction.
Reference numeral: 1, bridge pier; 2, bridge floor; 3, bridge column; 4, reserved steel bar head; 5, concrete; 6, reinforcing cage.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail: as shown in Figure 1, steel bow bridge bridge pier 1 is arranged on the below ground at steel bow bridge body of a bridge two ends, antetheca is vertical structure, when steel bow bridge pontic compressive deformation, bridge column 3 can resist the pressure of vertical direction, and tangential force is passed to bridge pier place by the body of a bridge 2, bridge pier 1 can resist horizontal tangential force, make steel bend bridge stress equalization, reduce steel bow bridging shape, reinforce steel bow bridge construction.
As shown in Figure 2, steel bow bridge cross section is very little trapezoidal of upper base, is namely convenient to piling operation, also Reinforced Concrete Materials is saved, known by Fig. 3 and Fig. 4, the inner vertical uniform much thicker reinforcing bars of bridge pier, are laterally connected by thinner reinforcement welding, form reinforcing cage 6 structure, outside concreting 5, wraps up reinforcing cage 6, prevents reinforcing bar by soil corrosion, reserved steel bar head 4 is only left in outside, and bridge pier is connected with pontic Member Welding by reserved steel bar head 4 with pontic.
By the utility model, the lifting surface area of steel bow bridge tangential force can be increased, steel can be made to bend bridge construction more firm, extend steel bow bridge application life.
Claims (4)
