Abstract:
1. A concrete wall fabrication system comprising: an endless track; a plurality of formworks for molding concrete into a number of concrete walls; a plurality of mold carriers movable on said endless track and adapted to carry said formworks to said concrete spouting unit and said vibrator unit, said mold carriers each comprising a plurality of wheels movably supported on said endless rack, pairs of supporting rods respectively pivotally arranged in parallel at different elevations, two vertical pressure bars, a plurality of sleeves respectively fixedly mounted on said vertical pressure bars at different elevations and respectively sleeved onto said supporting rods, a plurality of screw rods respectively stopped against said vertical pressure bars at different elevations, and hand wheels respectively mounted on said screw rods for rotation by the user to move said screw rods and to further force said vertical pressure bars against the formworks set in the respective mold carrier; a concrete spouting unit, said concrete spouting unit comprising a high-rise rack set above said endless track, a concrete container supported on the high-rise rack of said concrete spouting unit, and a concrete hose downwardly extending from said concrete container for guiding concrete out of said concrete container into the formworks in each mold carrier being moved on said endless track to the inside of the high-rise rack of said concrete spouting unit; and a vibrator unit, said vibrator unit comprising a high-rise rack set above said endless track, a hoisting motor fixedly provided at a top side of the high-rise rack of said vibrator unit, a rectangular suspension frame, a plurality of pulleys respectively pivotally mounted on four corners of said rectangular suspension frame and respectively supported on an inside wall of the high-rise rack of said vibrator unit to guide vertical movement of said rectangular suspension frame along the high-rise rack of said vibrator unit, a hoisting cable coupled between said hoisting motor and said rectangular suspension frame, a plurality of spring members vertically mounted on a bottom wall of said rectangular suspension frame, a vibration mount supported on said spring members, a vibration motor mounted on said vibration mount and adapted to vibrate said vibration mount, and a plurality of vibration rods vertically downwardly extending from said vibration mount for inserting into the concrete carried in between the formworks in each of said mold carrier to vibrate the concrete and to expel bubbles from the concrete.
