Abstract
A unique suspension device adapted to all styles and sizes of welded wire mesh concrete reinforcement fabric. The device rigidly suspends all schedules of reinforcing fabric in a predetermined, fixed parallel position with respect to the horizontal plane to which concrete is poured to form flat concrete slabs. The suspension device consists of a thin-walled bushing or ring composed of polyvinylchloride incorporating slots or cavities radially positioned at right angles to each other on its circumferal cross-section to accept, secure, and lock the reinforcing material into place to provide the desired level of suspension. The device maintains stacking characteristics in order to allow multiple parallel reinforcing fabric layering for industrial, high-stressed applications.
Claims1
A suspension device to hold welded wire fabric within a poured concrete slab said suspension device comprising a non-malleable cylindrical ring having a top surface and a bottom surface of equal diameter and a coupling device of the same characteristics and composition as said suspension device but having a diameter slightly larger than said suspension device and having a top surface and a bottom surface of equal diameter, wherein one of said suspension devices is received through the top surface of said coupling device and another of said suspension devices is received through the bottom surface of said suspension device such that said suspension devices and coupling devices facilitate unlimited stacking and layering of welded wire fabric.
