Abstract
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.
Claims20
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.
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, wherein said group contact propulsion member further comprises at least one track;
- 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 plurality of vertical support elements supporting said frame on said ground contact propulsion member, wherein said vertical support elements further comprise vertical telescoping hydraulic cylinders;
- 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 a first saw along said width of said paving slabs;
- a second saw support assembly comprising a second support member and a second saw assembly mounted in connection with said second support member for orientation of a second saw along said length of said paving slabs;
- 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 configured to operate concurrently with respect to a cut slot and sequentially with respect to a point on the slot.
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, wherein said group contact propulsion member further comprises at least one track;
- 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 plurality of vertical support elements supporting said frame on said ground contact propulsion member;
- a first saw support assembly having at least one first support member and at least a first saw mounted in connection with said first support member for linear motion of said saw along said width of said paving slabs;
- a second saw support assembly connected in parallel to the first saw support assembly, wherein the second saw support assembly comprises a second support member and a second saw mounted in connection with said second support member for linear motion of said second saw along said width of said paving slabs;
- a third saw support assembly comprising a third support member and a third saw mounted in connection with said third support member for orientation of said third saw along said length of said paving slabs, said third saw support assembly having an engaged position and a removed position;
- and
- wherein said first and second saws being mounted on said first and second saw assemblies, respectively.
