CONE ELEMENT FOR CONCRETE FORMS |
摘要 |
A cone-type device for use with form ties in concrete-forming systems to prevent escape of concrete and to facilitate form tie placing and form spacing operations. A cone device of size slightly smaller than the size of tie openings in the form elements is disposed on a form tie and is provided with a tapered end to facilitate introduction of said cones through the openings in the forms whereby the ties may be emplaced from a work station outside the form structure. The cone device is further used cooperatively with a form tie and a form lock as a spacer component to maintain accurate spacing of the form walls before concrete is poured notwithstanding its freedom from engagement with the form walls.
