This invention relates to the field of medical building ventilation equipment installation technology, and more particularly to a pre-embedded through-wall pipe device for hospital ventilation building construction. The device includes an arc-shaped bracket and mounting brackets; four mounting brackets are symmetrically arranged on the arc-shaped bracket; a rotating shaft I, rotatably arranged between the four mounting brackets; winding wheels, symmetrically arranged on the rotating shaft I, with the winding wheels located inside two adjacent mounting brackets; a rotating mechanism, with one end of the rotating shaft equipped with a rotating mechanism for driving the winding wheels to rotate; and a steel rope. The device is secured to the upper horizontal reinforcing bar by the arc-shaped bracket. The positions of the adjustment mechanism and the limiting mechanism are adjusted by the steel rope. The limiting mechanism adjusts the pre-embedded pipe to a horizontal state, and the adjustment mechanism can bend the reinforcing bar of the clamping plate to make it in close contact with the side wall of the pipe, facilitating welding.
