A constructional column improved
casting method comprises steps of manufacturing a
knife switch and a hopper, in which a discharging port is formed on a wooden template of a constructional column
casting surface, notches are processed on two sides of the upper port of the discharging port, a vertical groove mounted on a sealing surface of a concrete
casting top and having a groove bottom formed in the middle of the discharging port, and a through hole is formed under the vertical groove, inserting a
knife switch arm into the vertical groove, in which a cutter plate is tightly applied to the inner wall surface of the wooden template, and a U-shaped bolt is inserted into two perforations of the
cutting arm to fix the
knife switch, placing a discharging end of a feeding tank of the hopper on the discharging port of the wooden template, in which an upright surface formed by two triangular reinforced frameworks is tightly applied to the outer wall surface of the wooden template, a top hook is hung on the notches on two sides of the wooden template, and an L-shaped bolt is inserted into a nut and the through hole to fix the hopper, casting concrete to constructional
column space of the wooden template via the feeding tank until concrete stops entering, detaching the U-shaped bolt, hammering a knife switch
handle from bottom to top until a
cutting plate turns 90-degree, and getting the L-shaped bolt down and detaching the hopper. The constructional column improved casting method is safe, convenient and economical, and great casting quality can be achieved.
