  • Patent number: 7645503
    Abstract: The invention herein pertains to pavement marking patterns and the application thereof to roads, streets, walkways and the like. Various pattern designs for the markings are available to replicate layers of bricks, cobblestones, horizontal signage, logos and other components. The marking patterns are composed of two or more independent sections, the first section is a grid representing for example, the mortar joints in a brick wall. The second sections or inserts, for example represent bricks which are contained within the grid. As the first and second sections are generally formed from different colored, preferably thermoplastic materials, a hot melt adhesive spray is utilized on the bottom surface of the marking pattern to bridge the intersections between the first and second sections to maintain the integrity of the marking pattern for convenience during handling and application to a substrate.

  • Patent number: 7389620
    Abstract: Composite pan end connections for composite beam-joist construction are disclosed. Two versions of the composite pan can be fabricated on a standard break machine. A third version disclosed makes use of a standard steel stud. All three versions provide an economical, easily installed horizontal platform secured to the top chord seat angles of either conventional or composite open-web joists. In addition to economy in fabrication, and ease of use, the resulting rectangular shape of the concrete slab over the beam is structurally more efficient than heretofore obtainable.

  • Publication number: 20070234666
    Abstract: Tubular beams for building frames include laser-cut ends to form highly-accurate integrally-formed tab connectors for connecting the beams together and to other building beams. The tab connectors are integrally formed of continuous and contiguous material of the metal beam and are spaced apart to closely engage a second beam for secure and reliable and stress-distributed connection. The tab connectors can be formed and/or bent to define a pocket oriented at a desired angle for receiving a mating beam, such as for supporting a roof truss at a desired pitch. Fasteners extend through holes in the tabs and into or through the second beam for securing the beams together. The tab connectors can be cut to many different shapes, formed to any orientation, and made to accurately mate with corresponding structure of the mating second beam, regardless of the angle and size of the two beams.

  • Patent number: 7272914
    Abstract: A joist suitable for use in a composite concrete floor is disclosed. The joist comprises a top chord, a bottom chord; and a vertically extending intermediate web having a top end secured to the top chord and a bottom end secured to the bottom chord. The top chord comprises a pair of longitudinally continuous symmetrical chord members facing each other and embracing the top end of the web. Each of the chord members includes a vertical portion secured to the top end of the web and a slanting upper extension extending above and away from the top end of the web, thereby providing a shear connecting portion and a flared opening, between the two facing chord members, giving access to the web and improving access of a welding tool to the area between the symmetrical portion of the top chord and the web member that must be joined together.

  • Patent number: 7197854
    Abstract: A prestressed or post-tensioned composite structural system for bridge floors, road beds, pedestrian walkways, building floors, building walls, or similar structural elements. The structural system comprises a composite structure comprising an unfilled grating as a base component, and a prestressed, post-tensioned reinforced concrete slab as a top component. The base grating component is preferably a plurality of main bearing bars without any distribution bars or tertiary bars. The upper portions of the main bearing bars are embedded in the concrete component permitting horizontal shear transfer and creating a composite deck structure which maximizes the use of tensile strength of steel and the compressive strength of concrete.

  • Patent number: 7162844
    Abstract: A precast panel for building reinforced concrete walls has a metal liner that forms a front surface of the panel. A concrete mass is disposed behind the liner. The panel has reinforcement structure within the concrete mass that can be used to provide continuity of reinforcement between adjacent panels. Edges on the concrete mass are recessed, facilitating the connection of a splice end on a reinforcing bar with a splice end on an adjacent panel. The liner, reinforcement structure, and concrete mass form a composite steel-concrete structure.
