Abstract
A method and apparatus for forming a concrete block in form having a resilient insert forming a cavity in which the block is cast and a rigid support for the resilient insert. After the block has cured, the form is inverted. One or more areas of the insert are tethered to the support so that at least a portion of the insert can fall a short distance from the support. The weight of the cast block sufficiently deforms the insert to allow the block to fall free from the insert. When the form is again inverted to its upright position, the insert falls back into the support and returns to its original shape.
Claims18
A form for casting a concrete block including a rigid support, a resilient insert defining a cavity with surfaces shaped to provide a desired shape and texture to a block cast in said cavity, said resilient insert having an opening into said cavity, said support having a surface for supporting said resilient insert while a block is cast in said cavity, and at least one tether securing at least one predetermined area of said resilient insert to said frame whereby, when said form is inverted, at least the predetermined area of said resilient insert is free to fall a limited distance away from said frame and said tether allows said resilient insert to distort so that a cast block will fall from said resilient insert opening.
A method for casting a concrete block comprising the steps of:
- a) providing a form having a rigid support, a resilient insert supported by said rigid support while the block is cast in a cavity formed in said resilient insert, and wherein said resilient insert is tethered to said support;
- b) pouring concrete into said insert cavity through a top opening;
- c) allowing the concrete to cure;
- d) inverting said form to allow the tethered insert to fall from said support a distance limited by the tether and to distort sufficiently to allow the cured block to fall from said insert through gravity.
