Abstract
A concrete cutting saw has wheels and a rotating cutting blade that cuts a groove in the concrete surface. A support is mounted to the saw to support the concrete surface adjacent the cutting blade to reduce raveling. One or more nozzles are mounted to the saw and in fluid communication with a gas source to provide a gas stream directed toward the support so the gas stream from the nozzle impinges on a leading end of the support. The one or more nozzles are located adjacent to and in front of a leading end of the support, and preferably blow on opposing sides of the plane containing the cutting blade.
Claims25
A concrete cutting saw having wheels and a cutting blade that rotates to cut a groove in a concrete surface, the saw having a support for supporting the concrete surface adjacent the cutting blade to reduce raveling of the cut groove, the support having a leading end, comprising:
- a source of pressurized gas mounted on the saw;
- one or more nozzles mounted to the saw and in fluid communication with the gas source and providing a gas stream, at least one of the nozzles orientated to direct a gas stream toward the support so a gas stream from the nozzle impinges on a leading end of the support, the one or more nozzles being located adjacent to and in front of a leading end of the support.
A concrete cutting saw having wheels and a support for supporting the concrete surface adjacent a rotating cutting blade that extends through the support to cut the concrete surface, the support having a leading end, comprising:
- a source of pressurized gas mounted on the saw;
- nozzle means on the saw in fluid communication with the gas source for removing debris from in front of the support by blowing gas toward the skid plate.
A method for cutting a groove in a green concrete surface using a dry cutting concrete saw with a rotating cutting blade with a support supporting the concrete surface adjacent a leading end of the cutting blade to reduce raveling, comprising:
- from a location in front of the support, blowing at least one stream of gas in a rearward direction other than in the plane of the cutting blade, the stream impinging against a front of the support;
- and
- providing sufficient gas flow or pressure to the stream of gas to move debris from a path of the support.
