Protective enclosure for concrete anchor bolts

摘要

A protective cover for concrete anchor bolts includes a hollow, box-shaped housing having a bottom wall with a plurality of elongated, narrow slots thereon that are positioned and spaced to receive various patterns of cast-in anchor bolts. A top wall includes a plurality of wide openings to provide to access to the anchor bolts. Accordingly, a worker superimposes the housing onto a set of concrete anchor bolts with each received within one of the narrow slots on the bottom wall. Using the wider openings on the top wall, the worker tightens nuts onto the anchor bolts to secure the housing to the underlying concrete prior to pouring a surrounding floor. Once the surrounding concrete floor has dried, the nuts are removed and the enclosure is lifted from the formed indention.
