Abstract
Abstract A method of laying tile-like flooring members on a floor surface including forming on the surface an interconnected framework of a plurality of frame members to provide an array of recesses(11). In each recess a tile-like flooring member is laid having on its undersurface a projection (71) for snugly engaging the recess(11). Projecting edges of the flooring members extend over the frame members to engage each other and together form a continuous floor covering. The arrangement has the advantage of flooring effectively with carpet on a floor surface of an office room where a number of office apparatus are located with entangled creeping cables which shall be rearranged often afterwards.
