Abstract:
A plate support system, comprising:a plate having a perimeter edge and a substantially uniform thickness; and a support member having a bottom wall and a plurality of tapered side walls integrally attached to said bottom wall, said support member forming a continuous perimeter that defines an unobstructed opening adapted for positioning about a hole in a pavement surface for permitting work to be performed through said opening and in said hole, said opening being bordered by the bottom wall of said support member, the bottom wall of said support member having an upper surface for supporting the plate upon said bottom wall and a lower surface for resting on a pavement surface, the upper and lower surfaces of said bottom wall being substantially parallel to each other, each of said side walls having an inner stop surface extending upwardly from and substantially perpendicular to the upper surface of said bottom wall for restricting lateral movement of the plate off of said bottom wall when the plate is rested on the upper surface of said bottom wall; wherein each of said side walls has a top surface, a outer lower surface, and an outer intermediate surface which has a greater surface area than either of said top surface or said outer lower surface; wherein each of said side walls is tapered downwardly and outwardly from said top surface of said side wall to said outer lower surface of said side wall; wherein said outer intermediate surface of each of said side walls is slanted downwardly and outwardly from said top surface of said side wall to said outer lower surface of said side wall thus forming essentially a ramp portion; wherein said outer intermediate surface of each of said side walls is angled relative to said top surface and said outer lower surface; wherein said top surface of each of said side walls is disposed generally parallel to said bottom wall; wherein said outer lower surface of each of said side walls is disposed generally perpendicular to said bottom wall; wherein said bottom wall includes a plurality of holes spaced about and disposed through said bottom wall; wherein said holes includes a first set of said holes and a second set of said holes which is relatively larger than said first set of holes, said first set of said holes being adapted to receive fastening members for fastening a metal plate member upon said bottom wall, said second set of said holes being adapted to receive spike-like members for fastening the metal plate member and said support member to a road; wherein said bottom wall includes annular recessed portions being disposed in a bottom side thereof and being disposed about said first set of said holes, each of said annular recessed portions being adapted to receive a head of a bolt such that the head of the bolt is flush with said bottom side of said bottom wall; wherein said support member includes at least one spacer member securely and vertically disposed in said bottom wall and being spaced from said side walls which are disposed parallel to said at least one spacer member for allowing a plurality of metal plate members to be received and supported upon said bottom wall of said support member; wherein a height of the inner stop surface measured from the top surface of said bottom wall to a top surface of said side wall is substantially equal to the thickness of said plate; wherein the inner stop surface of said side wall has a shape and size about said opening substantially the same as a shape and size of the perimeter edge of said plate; and wherein said plate has a plurality of holes therethrough positioned for aligning with said plurality of holes in the bottom wall of said support member such that a fastener may be driven through said holes and into a pavement surface of a road.
