Abstract

The invention discloses an anti-leakage slurry device for pouring uprights, and relates to the technical field of pouring uprights; it includes a formwork, the formwork is provided with holes for piercing steel bars, and one side of the formwork is provided with holes in the circumferential direction of the holes. An annular groove, the steel bar is covered with an air bag, the air bag is located in the hole, the outer edge of the air bag is against the inner wall of the hole and the groove bottom of the groove, the inner edge of the air bag is in contact with the outer surface of the steel bar Surface bonding, the template is provided with an extruding plate on the side where the groove is located, and the extruding plate is sleeved on the steel bar, and the extruding plate leans against the template and squeezes the air bag into the hole. The leakage plugging effect of the invention is good.

Description

technical field [0001] The invention belongs to the technical field of pouring column devices, in particular to a slurry leakage prevention device for pouring columns. Background technique [0002] When pouring columns, it is often necessary to pass individual steel bars through the holes in the formwork and then pour them. Since there are gaps between the steel bars and the holes, corresponding tools are needed to block the gaps to prevent grout leakage. [0003] The plugging effect of the existing anti-leakage slurry device is poor. [0004] Chinese Patent Application Publication No. CN201924599U, the publication date is August 10, 2011, and the name is "exposed connection reinforced concrete plugging and grout stopper". Conical frustum with a circular base at the gap, the axes of the circular base and the conical frustum coincide, the diameter of the circular base is greater than the diameter of the conical frustum, and the axial middle of the conical frustum and the cir...
