SYSTEM AND METHOD FOR PLUGGING CORE HOLES

摘要

A system, device, and method for plugging core holes. A core hole plug includes a top compression plate, a bottom compression plate, and a rubber expansion ring that separates the top and bottom compression plates. A beveled screw hole can be created on the top compression plate. The beveled screw hole matches the angle of bottom surface of the head of a flat head bolt to ensure that the bolt remains flush with the top compression plate. The rubber expansion ring can be squeezed between the top and bottom compression plates as the flat head bolt is screwed into a threaded receiver nut formed on the bottom compression plate. An installation tool can be utilized to install the core hole plug so that the top compression plate remains flush with an existing floor surface.

主权项

1. A core hole plug installation system, comprising:
a core hole plug having a top compression plate and a bottom compression plate wherein said top compression plate and said bottom compression plate are separated by a rubber expansion ring plate and a rubber expansion ring; at least one beveled screw receiver on said top compression plate wherein said at least one beveled screw hole matches an angle of a bottom surface of the head of said at least one flat head bolt to ensure that said at least one flat head bolt remains flush with said top compression plate; at least one flat head bolt screwed into at least one threaded receiver nut through the beveled screw receiver wherein said at least one flat head bolt connects said top compression plate and said bottom compression plate of said core hole plug; and means formed on said top compression plate to temporarily attach a flat installation tool having a top and a bottom surface attachable to the top surface of said top compression plate, wherein said installation tool comes in contact with an existing floor surface when said core plug is inserted into a core hole for installation.
