INDEPENDENTLY SUPPORTED CONCRETE SAW APPARATUS AND METHOD

摘要

A saw apparatus is disclosed for sawing paving slabs. The saw apparatus has a frame mounted on a ground contacting propulsion member such that the frame straddles above a slab to be cut without touching the slab. A first saw support assembly disposes one or more blades of a saw in cutting engagement with the slab for a transverse cut. A second saw support assembly disposes a blade of another saw in cutting engagement with the slab for a longitudinal cut. The saw assemblies are configured to selectively, in a single pass along and over a slab, cut, vacuum, clean via pressurized air, fill a cut slot, and apply sealant to a cut slot concurrently with respect to a slot and sequentially with respect to a point of a slot.

主权项

1. A saw apparatus for sawing paving slabs, said paving slabs having a length and a width with said length being substantially greater than said width comprising:
a ground contacting propulsion member configured to straddle a paving slab; a frame mounted on said ground contacting propulsion member such that no part of said frame nor said ground contact propulsion member need contact the slab during operation; a first saw support assembly having at least one first support member and at least a first saw assembly mounted in connection with said first support member for linear motion of said saw assembly along said width of said paving slabs, said first saw support assembly having an engaged position and a disengaged position, said engaged position disposing a blade of said first saw assembly in cutting engagement with a top surface of said paving slabs; a second saw assembly comprising a saw oriented to cut lengthwise of said paving slabs; and wherein the first and second saw assemblies each include a vacuum, a compressed air delivery device configured to selectively direct a stream of air at a cut slot, a filler delivery device, a sealant applicator.
