Fabricated building connecting structure

The utility model discloses an assembly type building connecting structure which comprises a wall plate, a plurality of first penetrating pipes and second penetrating pipes are symmetrically arranged on the outer walls of the two sides of the wall plate in a penetrating mode, the ends, located in the wall plate, of the first penetrating pipes are communicated with a first shell, and an inner threaded pipe is rotationally connected into the first shell. The inner threaded pipe and the first penetrating pipe are coaxially arranged, a driving mechanism is installed on the first shell in a penetrating mode, the driving mechanism is in transmission connection with the lantern ring, and the end, located in the wall plate, of the second penetrating pipe communicates with a second shell. During use, the connecting rod penetrates into the first shell through the first penetrating pipe, so that the connecting rod abuts against the internal thread pipe, then the driving mechanism drives the internal thread pipe to rotat
