Apparatus and method for preparing a site and finishing poured concrete
First Claim
1. A wheel for supporting a concrete processing vehicle, said wheel comprising:
- a hub portion rotatably mountable to a concrete processing vehicle to be operated within the confines of an area prepared to receive concrete, wherein the area has a base surface atop which concrete is poured and at least one concrete reinforcing element located above the base surface, wherein said hub portion has a first end and a second end distal thereto and said first and second ends define a central axis extending therebetween, and wherein said hub portion includes a rim surface extending radially about said central axis and between said first and second ends; and
,a plurality of base surface-contacting members extending from said hub portion, each base surface-contacting member of said plurality of base surface-contacting members having a shape which urges a concrete reinforcing element away from entrapment between said base surface-contacting member and the base surface upon contact between said base surface-contacting member and the concrete reinforcing element, wherein each said base surface-contacting member is elongated and has a first end at said rim surface and a second end distal thereto.

Abstract
A site preparation/concrete finishing apparatus for operation in an area having a base surface above which concrete reinforcing elements have been positioned prior to pouring of concrete within the area and for use in finishing concrete poured within the area. The site preparation/concrete finishing apparatus comprises a movable vehicle having at least one lift arm, a plurality of specially-tailored wheels for supporting the movable vehicle entirely within the area in continuous contact with the surface and for enabling continuous movement of the movable vehicle relative to the surface absent damage to the concrete reinforcing elements beneath the movable vehicle, and a concrete finishing device connected to the lift arm for fine grading and leveling of the area and for screeding and floating concrete poured within the area. Each wheel of the plurality of wheels includes a hub and a plurality of members extending radially therefrom. Each member of the plurality of members has a first end near the hub and a distal second end, and includes an arcuate surface proximate the second end. Each member also tapers over at least a portion of the distance between the first and second ends. The arcuate surface of each member aids in preventing the trapping of a concrete reinforcing member between the base surface and the site preparation/concrete finishing apparatus. The tapered portion of each member tends to direct a concrete reinforcing member contacted by the member slidably away from a longitudinal axis of the member.

8. An apparatus for finishing concrete operable within an area prepared to receive concrete wherein the area includes a base surface above which at least one concrete reinforcing element is located, said apparatus comprising:
-
a movable vehicle including a plurality of wheels mounted for rotation, wherein said wheels of said plurality of wheels are operable to entirely support said movable vehicle relative to the base surface and to enable movement of said movable vehicle within the confines of the area prepared to receive concrete absent displacement of a portion of a concrete reinforcing element from a first position to a second position from which the portion of the concrete reinforcing element cannot by itself resume the first position; and
,a concrete finishing device operatively connected to said movable vehicle. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A method of producing finished concrete, the method comprising the steps of:
-
positioning a movable vehicle having a plurality of wheels and a concrete finishing device operably attached thereto within the confines of an area configured to receive concrete, wherein the area includes a base surface and at least one concrete reinforcing element located above the base surface, wherein the wheels of the plurality of wheels contact the base surface and entirely support the movable vehicle, and wherein each wheel of the plurality of wheels has a protruding member for urging a concrete reinforcing element away from entrapment between the wheel and the base surface; moving the movable vehicle within the confines of the area and with the plurality of wheels in contact with the base surface; pouring concrete within the area; and
,finishing concrete poured in the area with the concrete finishing device. - View Dependent Claims (17, 18, 19, 20, 21)
