Abstract
Disclosed is an improved packerhead or drycast concrete product forming apparatus and method for making a concrete product therewith. The apparatus typically includes a mold having a lower curing pallet, a platform for supporting said mold at the pallet, and a vibrator table having a vibrator ring for association with said curing pallet. The improved apparatus of the present invention preferably comprises a vibrator ring having selectively engageable (and disengageable) means to rigidly connect the vibrator ring to the curing pallet when said vibration means is activated. The preferred vibrator ring selectively engageable means comprises electromagnet means and the preferred product of the process comprises concrete pipe.
Claims11
A concrete pipe forming apparatus including a mold containing a lower curing pallet, a platform for supporting said mold, a vibrator table having vibration means and drive means for rotating said table, and a vibrator ring attached to said vibrator table for transmitting vibration and rotary movement from said vibrator table to said lower curing pallet, the improvement comprising said vibrator ring having selectively engageable means to rigidly connect said vibrator ring to said curing pallet when said vibration means is activated.
In a method for forming a concrete pipe which includes casting concrete material in a pipe mold containing a lower curing pallet, vibrating and rotating a vibrator table having vibration means and rotary drive means and transmitting vibration and rotation from the table to the pallet using a vibrator ring attached to said vibrator table, the improvement comprising:
- rigidly connecting said vibrator ring and said lower curing pallet with selectively engageable means when said vibration means and said drive means are activated;
- and
- disengaging said engageable means thereafter.
