Abstract
Abstract The present invention provides a flooring system that can be quickly, accurately and easily installed in various sorts of buildings, including temporary structures, pre-fabricated buildings or permanent structures such as factories, homes or offices. The flooring system broadly consists of individual panel assemblies that may be cooperatively interengaged. The periphery of each panel is bound by frame members having two spaced generally parallel flanges and a generally perpendicular web extending therebetween. On one side of the web, between the upper and lower flanges, the frame members include a track for receiving a key block. The key block comprises a generally rectangular base with a key tongue extending therefrom. The base is slidably received in the track of one frame member and the tongue is received in the track of an adjacent frame member. The frame members may be miter cut to a desired length and the corners fastened together by a corner fastener.
