Apparatus for vertical slipforming of concrete walls

Apparatus for vertical slipforming of concrete walls, comprising

• (a) a mobile rigid integral frame;
• (b) at least one strongback assembly suspended from said frame;
• (c) a plurality of slipform assemblies connected with said strongback assembly, each of said slipform assemblies comprising a pair of spaced adjustable vertical forms having opposed planar surfaces defining a cavity;
• (d) concrete supply means connected with said frame for delivering concrete to said cavities of said slipform assemblies;
• (e) means for vertically displacing said slipform assemblies incrementally relative to said frame as the concrete sets within said cavities and further concrete is supplied thereto, thereby to continuously and simultaneously cast a plurality of concrete panels having a vertical orientation;
• (f) means for controlling said concrete supply means and said vertical displacing means in accordance with progressive setting of the concrete within said cavities, thereby to continuously and simultaneously cast a plurality of concrete panels having a vertical orientation with maximum efficiency;
• (g) means for sensing the position of said vertical displacing means and said slipform assemblies and for sensing the condition of the concrete during the slipforming operation, said sensing means producing output signals to said controlling means which processes said signals and adjusts said concrete supply means and said vertical displacing means responsive to said signals, thereby to automate the slipforming operation;
• and
• (h) a plurality of ground-engaging wheels connected with a bottom portion of said frame enabling said frame to be transported to and positioned along the ground at a job site for forming vertical walls at a desired location.
