There is U-shaped reinforcing steel bar, the U-shaped reinforcing steel bar binding is on the stirrup of epimere precast concrete column.
The anchor bolt extended laterally is equipped on the connecting seat.
Keyway is equipped in the top surface of the bottom surface of the epimere precast concrete column and the hypomere precast concrete column.
The utility model has the advantages and positive effects of：The vertical muscle of upper and lower precast concrete column is connected using connecting seat
It being connected together, simplifies the overlap joint work of node area reinforcing bar, operation is poured after greatly reducing node area, installation process is easy,
Special tool(s) is not needed to, accelerates speed of application；Simple in structure, power transmission is reliable so that the construction quality of prefabricated post connection is more
It is easy to ensure；Construction cost is low, is conducive to the popularization and application of assembly concrete frame structure, have significant economic benefit and
Social benefit.
