Abstract
A concrete cutting or milling apparatus has a milling head carrying a power driven circular saw blade or milling cutter movable along a guide rail having a plurality of guide rail sections that may be coupled to each other in the longitudinal direction. The guide rail sections are supported by a foot structure that can be screwed to a concrete member, such as a wall or floor, to be cut. The foot structure is releasably secured to the guide rails however in a torsion stiff manner. Further, the foot structure is provided with adjustment screws for the proper axial alignment of the guide rail sections relative to each other to provide for a correction of the rail position and for compensating an uneveness in the surface of the concrete member to be cut. The structure is lightweight and one operator can secure the rail sections to a concrete surface. The rail sections form a closed cross-sectional tubular shape which may be round or substantially box shaped.
