A machine for imprinting patterns onto uncured concrete in an elongated bed includes a frame for positioning the finishing machine over the bed. A lower patterning unit suspended from the frame is movable backward and forward of the concrete bed and a press assembly moves the pattern in and out of contact with uncured concrete on the elongated bed.

Concrete finishing machine

A system for automating the casting of concrete panels in which a bed position indicator is fed to a program which compares the bed position to CAD drawings concerning the concrete to be cast and sends the drawing detail for the position of the bed which is then shown on the bed by a laser.

Automated concrete casting system

Improved premolded foam billets and drop-in foam billet joints increase the R value in concrete panels.

Insulated concrete panel billets

A segmented concrete screed for screeding concrete on a concrete casting bed includes a plurality of individual screed units each of which may be raised and lowered independently of the others such that screeding operations may selectively bypass obstructions in the concrete to be screeded.

Segmented concrete screed

An improvement to concrete casting machines of the casting bed type in which the side forms are constructed and arranged to stay in an upright position at all times but may be raised and lowered.

Variable height sideforms

A method for casting hollow core concrete panels includes the use of raft connectors to hold a plurality of spaced foam billets in place during the manufacture to create panel or plank with spaced foam-filled cores. The panels include billets that form longitudinal voids that allows utilities to be run through the lengths of the concrete panels.
