Method and apparatus for manufacturing concrete panels by continuous pressing

Abstract

A method for manufacturing concrete panels by continuously pressing and an apparatus for carrying out the method. The concrete panels are successively manufactured by continuously feeding pallets onto a conveyor, feeding a concrete material onto the pallets, continuously pressure frames against the concrete material from the upper side and both lateral sides of the concrete material while imparting vibrations to the pressure frames, forming hollows in the concrete material by thrusting a rotary screw-type core rod therethrough to provide a panel shape hollow molding, and cutting the molded concrete material into a length corresponding to the length of each pallet. In the manufacture process, an organic or inorganic fiber material may be incorporated into the concrete material for the purpose of reinforcement of the finished products.
