Novel fabricated concrete member dry type connecting device

The invention relates to a novel assembly type concrete member dry-type connecting device which is composed of concrete members, long screws, a force transmission base plate, thin steel pipes, longitudinal bars and nuts, the upper concrete member and the lower concrete member are in dry-type connection through clamping grooves and welding, the longitudinal bar portions of the upper concrete member are welded to the force transmission base plate, bolt hole channels are formed in the force transmission base plate, and the nuts are connected with the long screws. The hole channel is matched with a long screw rod of the lower concrete member, and the long screw rod and a reinforcement cage in the lower concrete member are welded into a whole to be prefabricated; during installation, the long screws can penetrate through the hole channels, penetrate out of the side face of the upper concrete member through the thin steel pipes and the cushion blocks and are connected through nuts. In this way, grouting and cast-in
