| 20110150571 | CLAMP DEVICE FOR PORTABLE POROUS PAVEMENT SYSTEM - A clamping device for a portable porous pavement system includes a first bracket and a second bracket. The first bracket includes a U-shaped section extending between first and second wings; a first slot defined by the first wing; and a second slot defined by the second wing. The second bracket includes a C-shaped member having first and second arms with a base member joining the first and second arms; a first twistable section defined by the first arm; and a second twistable section defined by the second arm. The first arm is sized to fit through the first slot of the first wing such that the first twistable section and the base member are on opposite sides of the first wing; and the second arm is sized to fit through the second slot of the second wing such that the second twistable section and the base member being on opposite sides of the second wing. | 06-23-2011 |
| 20120237294 | ROAD RESTORATION BLOCK - The present invention relates to a road restoration block for covering eliminated pavements during various road constructions conducted by eliminating some of or the entire existing road pavements, and more specifically, to a road restoration block, which can quickly and safely cover the eliminated pavements by providing blocks that are simply carried, disposed, and disassembled with strong coupling power to the upper part of the eliminated pavements so that people and cars may pass even when the constructions are in progress, thereby providing a safe and pleasant construction environment by preventing the traffic congestion caused by the constructions. | 09-20-2012 |
| 20130115000 | REMOVABLE DOWEL CONNECTOR AND SYSTEM AND METHOD OF INSTALLING AND REMOVING THE SAME - A pre-fabricated pavement slab installation and replacement system is provided. The system includes a connector having an axial opening therethrough and engagement surface within the opening. The system further includes a pavement slab and an adjacent pavement slab, wherein a portion of the connector is embedded in the pavement slab and a remaining portion of the connector is exposed. The adjacent pavement slab has an interconnection slot, that can cover the remaining portion of the exposed connector. The system further provides that under the condition that the pavement slab and the adjacent pavement slab are cut apart, the connector is cut into a first half and a second half, wherein the first half of the connector contains the first engagement component and the second half of the connector contains the second engagement component. The first half of the connector can be subsequently removed by engaging the engagement surface. | 05-09-2013 |
| 20130279978 | TACTILE EMBEDMENT PLATE ASSEMBLY WITH AN ALIGNMENT BRACKET - Tactile detection embedment plates used in pedestrian walkways releasably aligned by a bracket on at least one of the embedment plates. The bracket can be mated with a bracket on another plate to define a receiver yoke in which a wedge is disposed for a releasable plate assembly connection. | 10-24-2013 |
| 20140270946 | MODULAR CONCRETE UNIT AND AN ASSEMBLY THEREOF - A modular concrete unit for load-bearing surfaces, and a concrete assembly having at least two modular concrete units connected by a hinging attachment. The modular unit has a top surface, a bottom surface, and at least three side walls extending between the top and bottom surfaces. The side walls of each modular unit include at least one engagement means configured for hinging attachment to a neighboring modular unit. The concrete assembly made from at least two modular units further includes at least one hinge pin connecting the engagement means of a first concrete unit and the engagement means of a second concrete unit. | 09-18-2014 |
| 20140270947 | PAVEMENT SLABS WITH SLIDING DOWELS - A pavement slab including top and bottom surfaces, first and second longitudinal side surfaces, and first and second transverse side surfaces. The slab includes a first and second plurality of transverse holes formed within the first and second longitudinal side surfaces, respectively, a first and second plurality of longitudinal holes formed within the first and second plurality of transverse holes, respectively, and plurality of dowel bars. Each of the holes is sized and shaped to receive slidably a corresponding one of the plurality of dowel bars. Each of the dowel bars is slidable between a retracted position and an extend position in which the dowel bar forms a joint between the slab and another slab or preexisting pavement. | 09-18-2014 |
| 20150098757 | PLAYGROUND MATS - Systems and methods are described for connecting a first mat tile to a second mat tile, including, but not limited to, a first bracket embedded in the first mat tile and a second bracket embedded in the second mat tile. In various embodiments, the first bracket includes a first pin hole while the second bracket comprising a second pin hole. Systems and methods further include a pin coupled to the first bracket through the first pin hole and to the second bracket through the second pin hole. | 04-09-2015 |
