Abstract
Method and apparatus for the manufacture of pre-cast plate-like concrete elements on a building site. A horizontal casting table has a large area mold into which the concrete is poured. After a short setting time to allow the concrete to harden, the table is raised to a vertical position and the partially hardened concrete element is drawn off of the mold. The process of moving the table to a vertical condition is accompanied by a lateral movement such that the latest element is stacked at the head of a line of previously cast elements. The elements are allowed to stand undisturbed until hardening is complete. Casting is done in a movable shed which shelters the partially hardened elements from the weather. Ribbed elements may be cast using a further mold element raised and lowered from the ceiling of the shed.

Apparatus for casting plate-like concrete wall elements comprising a casting table, a wide area mold affixed thereto, said casting table being supported by a pair of curved runners, said casting table being stable when said wide area mold is in a horizontal position and rockable upon said pair of curved runners to place said wide area mold in substantially a vertical position, removal means operable to separate said wide area mold from said concrete wall element when said wall element is in the vertical position, said removal means including a member forming the lowest part of said wide area mold when said wide area mold is in a vertical position.
An apparatus for casting concrete wall sections comprising:
- a movable shed movably mounted on track means;
- a casting table movably mounted within said shed on said track means;
- said casting table being mounted on a pair of curved runners and having a wide area mold affixed thereto;
- said casting table being stable when said wide area mold lies in a horizontal position and being raisable to a vertical position by being rocked on said curved runners;
- removal means for separating said casting table laterally a predetermined distance from said concrete wall sections after casting;
- said removal means being further operable to move said shed laterally a distance corresponding to the displacement of said casting table.
