20090317189 | PROTECTION SYSTEM FOR SURFACES OF INFRASTRUCTURE IMPROVEMENTS IN A CONSTRUCTION ENVIRONMENT - A protection system comprises a body section and optional ramps for facilitating travel over the body section. The protection system may comprise base and arm members, which have bottom surfaces at different elevations to fit over an elevation change. In use, the protection system is installed over a surface to be protected, which may be a portion of an infrastructure improvement, such as a sidewalk, curb, gutter, or other structure. Traffic crossing the surface of the infrastructure improvement is then directed over the protection system, where the topical load from the traffic is distributed across the surface. When the use is complete, the protection system may be removed from the surface. | 12-24-2009 |
20140017007 | CONDUIT FOR PERVIOUS PAVEMENT - A conduit for the formation of pervious pavement includes a first portion and a second portion joinable to the first portion. The first portion includes a pair of first receiving notches and a pair of third receiving notches oriented perpendicular to the first receiving notches. The second portion includes a pair of second receiving notches and a pair of fourth receiving notches oriented perpendicular to the first receiving notches. When the first and second portions are joined to one another, the pair of first receiving notches cooperates with the pair of second receiving notches to define a pair of first attachment openings for receiving a first structural member of a reinforcing mesh, and the pair of third receiving notches cooperates with the pair of fourth receiving notches to define a pair of second attachment openings for receiving a second structural member of the reinforcing mesh. | 01-16-2014 |
20140017008 | CONDUIT FOR PERVIOUS PAVEMENT - A conduit for the formation of pervious pavement includes a first connector and a second connector joinable to the first connector. The first connector includes a pair of first receiving notches. The second connector includes a pair of second receiving notches oriented perpendicular to the first receiving notches. When the first and second connector are joined to one another, the pair of first receiving notches cooperates with the second connector to define a pair of first attachment openings for receiving a first structural member of a reinforcing mesh, and the pair of second receiving notches cooperates with the first connector to define a pair of second attachment openings for receiving a second structural member of the reinforcing mesh. First and second tubes are inserted into the first and second connectors to complete the conduit assembly. | 01-16-2014 |

20110255920 | Dowel sleeves - A dowel sleeve has a tubular body with a mounting assembly at one end for releasable connection to a construction plate, and a leg support engagable at the other end for adjustable support. The construction plate has spaced non-circular holes. A first flange of the mounting assembly has a complementary profile, of smaller dimensions, to the non-circular holes, while a second flange has a similar profile, of larger dimensions, with its major-axis non-aligned with the major-axis of the first flange. The first flange is inserted through one of the non-circular holes, and the tubular body is rotated so the first and second flanges engage opposed faces of the construction plate. | 10-20-2011 |
