Abstract: A skid plate for a concrete saw has opposing ends connected by a truss, with mounting fixtures that connect opposing ends of a skid plate to the concrete saw. The mounting portions are connected to an apparatus that simulates the saw's mounting structure, and that simulates the load distribution the saw exerts on the skid plate in use. Sensors detect the force or deflection at various locations on the skid plate that occurs from the simulated load. One end of the truss and skid plate are moved relative to each other to adjust the sensor readings on the skid plate to achieve a predetermined profile that reduces raveling of a concrete surface during cutting.

Abstract: A skid plate assembly for a concrete cutting saw is provided. The skid plate assembly has a slot through which the rotating cutting blade passes to cut the concrete. Springs located on opposite sides of the cutting blade resiliently bend the skid plate to counteract deformation of the skid plate as it is placed against the concrete. The spring and skid plate being sized to allow bending to accommodate variations in the flatness of the concrete surface during cutting so that it remains in sufficient contact with the surface of the concrete surrounding the cutting blade to reduce raveling.

Abstract: A mounting for use in mounting rotating cutting blades to the drive shaft of saws is provided. The mounting is an arbor or arbor sleeve having a non-symmetrical outer mounting surface onto which is mounted a cutting blade which contains a similarly configured mounting hole. The arbor or arbor sleeve is designed for use with a cutting blade having a mounting hole which, when viewed from one side of the blade is the same as the outer surface mounting surface, and which viewed from the other side of the blade is not the same. The use of the arbor or arbor sleeve of the present invention with a cutting blade having these characteristics results in the blade being mounted on the saw in only one orientation.

Abstract: A concrete cutting saw is provided for the cutting of grooves in the surface of wet concrete. The concrete saw generally comprises a motor driven rotating cutting blade mounted on a support structure. The concrete saw is supported during cutting by wheels, and has a skid plate with a slot through which the rotating cutting blade passes to cut the concrete. The cutting blade is mounted with a sound deadening blade housing and a number of shields and guards located about the skid plate. The skid plate is movably attached to the concrete saw and resiliently urged against the concrete during cutting so that it remains in contact with the surface of the concrete surrounding the cutting blade during cutting. The skid plate is constrained into a bowed configuration so that it is substantially flat during cutting. A variable speed transmission is drivingly connected to the wheels to propel the saw across the concrete during cutting.
