Abstract
The present invention provides a floor through-passage molding apparatus adapted for a floor construction having steel bars, includes: a forming sleeve and a constricting module. Said forming sleeve has a sleeve wall forming an outer circumference surface. Said constricting module has an elongated curved body disposed on said sleeve wall, and a first connection terminal and a second connection terminal are respectively located on two opposite ends of said elongated curved body. By connection of said first connection terminal with the second connection, said elongated curved body can radially support outer the circumference surface of the sleeve wall to reinforce the entire structure of the forming sleeve and thereby prevent the floor through-passage molding apparatus from deforming or slanting, and simultaneously reinforce a firm connectivity between the floor through-passage molding apparatus and the concrete floor.
