The utility model discloses a realize through following technical scheme:

namely a connecting node of an assembled concrete beam column, which comprises a prefabricated column, prefabricated spliced pole has two prefabricated roof beams, be equipped with prefabricated bracket post on the both sides face of prefabricated post upper portion, the inside many embedded steel bars that are equipped with of prefabricated post, the inside many pre-buried steel pipes that is equipped with of prefabricated spliced pole, two notches have been seted up in the lower part of prefabricated spliced pole, every prefabricated roof beam is inside all to be equipped with a pre-buried frame, pre-buried frame is connected with a linking frame through a plurality of splice bars, the front end of prefabricated roof beam is placed on prefabricated bracket post, linking frame is located the outside of prefabricated roof beam, linking frame is inside to be equipped with two bearing steel boards, a plurality of through-holes have been seted up on the bearing steel board, connect through high strength bolted connection between the bearing steel board on two linking frame, high strength bolt is fixed through the nut of both ends installation, prefabricated spliced pole corresponds the cover through pre-buried steel pipe and installs on prefabricated post.

The utility model discloses cancelled the group between sleeve and the reinforcing bar between the beam column to, reduced the accuracy requirement to the installation, it is more convenient to assemble, and the installation node between the beam column is more firm, and intensity is higher, and the shock resistance is also stronger.

Further preferably, elastic gaskets are arranged at two ends of the high-strength bolt, and the high-strength bolt is fixedly arranged by pressing the elastic gaskets through a nut.

Further preferably, the inside embedded steel bar that still is equipped with of prefabricated spliced pole, this embedded steel bar stretches out by the upper end of prefabricated spliced pole.

Compared with the prior art, the utility model discloses the beneficial effect who has is:
