Bent cap in the structure is attached with pier column using high-strength bolt at the scene completely by prefabrication, and cast-in-place portion is not present
Point, simple and quick construction, can, not environmentally construction problem uncivil to avoid noise, the dust of construction site etc., social benefit is aobvious
It writes.
For this purpose, the utility model uses following technical scheme：
A kind of prefabricated assembled bent cap structure, including bent cap, short column section and ring flange；The bent cap is that full batch production is prefabricated
Part；The lower end of bent cap is equipped with several short column sections, and the number of short column section and the number of bridge pier are consistent；The lower end of short column section and bridge pier
Upper end is respectively equipped with ring flange, is connected between two ring flanges by high-strength bolt.
Further, the bent cap is made of reinforcing bar and concrete material, and the short column section uses steel reinforced concrete system
Make, the bent cap and short column section are integrally poured in factory.
Further, it is connected by the way of welding between the reinforcing bar in the short column section and the lower end and ring flange of fashioned iron
Together.
Further, the bridge pier is made of armored concrete, and the steel inside bridge pier upper section built-in profile steel, bridge pier
It is linked together by the way of welding between muscle and the upper end and ring flange of fashioned iron.
Further, the fashioned iron includes I-steel, channel steel, angle steel, round steel.
Preferably, the ring flange is rectangular or round, the bolt hole for being surrounded by certain amount of ring flange, the spiral shell
Keyhole matches with high-strength bolt.
Compared with prior art, the utility model has the beneficial effects that：
(1) it using complete fabricated construction method, is attached between bent cap and bridge pier by ring flange and high-strength bolt,
It no longer needs to carry out injecting treatment.
(2) construction period is shortened, bridge construction speed is accelerated.
(3) simple and quick construction, can, not environmentally construction problem uncivil to avoid noise, the dust of construction site etc., society
It can remarkable benefit.
