Description

Single column pier steel plate combination bent cap ruggedized construction

Technical field

The utility model relates to a kind of Single column pier column ruggedized construction, in particular to a kind of Single column pier steel plate combination bent cap is reinforced Structure.

Background technique

With the continuous construction of China's Single column pier bridge, technology also in continuous maturation, has been widely applied to urban interchange, height In the construction such as fast highway, the structure type of Cast-in-Situ Continuous Beam is used in most processs of construction, under this Cast-in-Situ Continuous Beam Portion's structure type is broadly divided into Single column pier and two kinds of twin shaft pier, it can be seen that entire bridge floor in the design structure of Single column pier bridge Only one intermediate fulcrum, this fulcrum play specific supporting role for bed rearrangement bridge.All vehicles travelled on bridge floor Weight is all within the tolerance range of this support force.Vehicle will not be generated in normal driving process Bridge uniform force Safety problem, but seesaw phenomenon can be generated phenomena such as overload of vehicle, automobile are not travelled along bridge center line, cause Entire bridge structure occurs bridge rollover in the case where discontinuity equalization or phenomena such as support falls off, for the safety of people Trip brings great security risk.

In consideration of it, in order to improve traditional solely pier structure unbalance stress, transformation reinforced construction method is not good enough, construction cost is high and The problems such as long in time limit, it would be highly desirable to invent a kind of simple and effective Single column pier steel plate combination bent cap ruggedized construction, improve Single column pier and reinforce Construction quality and construction efficiency.
