  • Method of making a concrete column with a concrete column forming tube
    Patent number: 5376316
    Abstract: A lightweight concrete forming tube is disclosed, and wherein the tube has a very thin wall of wound paper layers which permit the tube to be collapsed and wound into a reel to facilitate shipment and storage. In use, the desired length is severed from the reel, and the severed length is opened and positioned about a vertically disposed steel reinforcing structure. Concrete is then poured into the opened tube, and the hydrostatic pressure of the liquid concrete causes the tube to assume a circular cross-section and straight vertical configuration. Upon hardening of the concrete, the tube is severed with a knife and removed, leaving a formed concrete column of circular and straight configuration.
    Type: Grant
