Claims13
A pocket former for use with a stressing end anchor and a concrete form, wherein the concrete form is adapted to contain concrete that encases the stressing end anchor, comprising:
- a pocket former body, the pocket former body having an outer surface, an outer edge, and an inner edge, the pocket former body being tapered between the outer and inner edges and including at least one longitudinal pocket former bridge, the pocket former bridge being positioned between the outer and inner edges and oriented longitudinally along the pocket former body;
- and
- a collapsible element, the collapsible element formed on the outer surface of the pocket former body, the collapsible element extending radially outwardly from the pocket former body;
- wherein the pocket former is adapted to be positioned between the stressing end anchor and the concrete form so as to prevent or restrict the concrete from filling a space between the stressing end anchor and the concrete form;
- and
- wherein the pocket former bridge is adapted to break upon the application of a force on the collapsible element, separating the pocket former body into two or more longitudinal portions and allowing removal of the pocket former from the concrete, thereby leaving a pocket in the concrete.
A pocket former for use with a stressing end anchor and a concrete form, wherein the concrete form is adapted to contain concrete that encases the stressing end anchor, comprising:
- a pocket former body, the pocket former body having an outer surface, an outer edge, and an inner edge, the pocket former body being tapered between the outer and inner edges and including a plurality of one pocket former bridges between the outer and inner edges;
- and
- a plurality of collapsible elements, each collapsible element being between two pocket former bridges and formed on the outer surface of the pocket former body, each collapsible element extending radially outwardly from the pocket former body;
- wherein the pocket former is adapted to be positioned between the stressing end anchor and the concrete form so as to prevent or restrict the concrete from filling a space between the stressing end anchor and the concrete form;
- and
- wherein the application of force to the pocket former pushes the collapsible element into the pocket former body, thereby causing an inward force that breaks the pocket former bridge, thereby separating the pocket former body into two or more portions and allowing removal of the pocket former from the concrete, thereby leaving a pocket in the concrete.
