Abstract
A system for forming thin-wall pre-cast concrete forms and structures, using vertical casting and slip-form techniques to partition wet concrete into separate thin-wall sections, the system being particularly useful for fabricating pre-cast concrete column forms having a composition and vertical consistency substantially the same as the integral poured concrete core of the finished concrete column.
Claims5
A method for forming thin-wall concrete structures adapted for concrete forms comprising the steps:
- providing an outer form unit with sides and a bottom wherein the sides and bottom form a container;
- filling the outer form unit with poured wet concrete;
- providing an inner form unit;
- inserting the inner form unit downwardly into the wet concrete in the outer form unit wherein the wet concrete is divided into separated vertical volumes;
- releasing one of the separated vertical volumes of wet concrete through the bottom of the outer form;
- partially curing the concrete to form one or more concrete structures;
- removing the outer form unit and inner form unit from the partially cured concrete structure;
- and,
- curing the concrete structure.
