Crossed Reinforcing Rods With Connector Patents (Class 52/719)
  • Patent number: 10280621
    Abstract: A method for securing rebar prior to concrete pour consists of tying, by hand in a series of unique steps, a piece of wire with 2-inch loops on either end around the rebar at joints where the rebar sections come together. The present method is used in place of a mechanical system as required in the prior art and requires no tools or other devices. Execution of the present method is up to 7 times faster and results in a stronger tie than other tying methods. The present method provides substantial savings in manpower and time on any application requiring reinforced concrete.

  • Patent number: 10106984
    Abstract: Tool Free Rebar Tie—A metal wire tie consisting of a piece of 16 gauge wire between 8 and 12 inches long with a loop on each end and each loop closed with a twist. The inventive device is used to fasten rebar on construction sites prior to a concrete pour. The user grips the wire, placing gloved fingers through the loops, and wraps the wire around the joint where two rebar sections come together. The tie is used in place of a mechanical system and requires no tools or other devices to fasten the metal rods which reinforce concrete. Application of the tie is 2-3 times faster than the method currently in use providing substantial savings in man power and time for virtually any construction job where reinforced concrete is required.

  • Patent number: 9097010
    Abstract: A simple, one-piece mechanical tie allows quick and secure connection between rebar, mesh and form. A single piece of tie wire can secure the tie to the mesh and rebar, making the installation process much quicker than conventional processes. Unlike other devices that have multiple pieces where, if one piece is lost, the tie is unusable, the current device is designed as a single piece making installation and use quick and simple.

  • Patent number: 7322158
    Abstract: A concrete reinforcing bar support has a base, a support structure extending upwardly from the base with a channel formed at an upper surface thereof, a first clamping structure affixed to the support structure on one side of the channel, and a second clamping structure affixed to the support structure on an opposite side of the channel. A first rebar extends through the channel. A second rebar is retained by the first and second clamping structures in a direction transverse to the first rebar. Each of the first and second clamping structures has generally C-shaped configuration.

  • Patent number: 7241071
    Abstract: A fastener for joining two pieces of rebar together in a rebar grid used to reinforce subsequently poured concrete is described. The fasteners include two clamp pieces that in certain embodiments completely wrap around a piece of rebar and are tightly secured thereto. Further, each clamp piece can swivel or rotate up to 360 degrees relative to the other clamp piece such that two rebar pieces intersecting at any angle can be coupled together.

  • Patent number: 7040059
    Abstract: Adjustable apparatus for bracing one or both sides of a wall being fabricated from masonry blocks and having an opening near the base of the block wall. Bracing system includes strong rigid members assembled in the form of a right angle brace set having stiff vertical, horizontal and diagonal members, a connector having a length sufficient to extend through the opening affixed at a right angle location of one or both of the brace sets. A pair of such braces—back to back, and spaced on opposite sides of a wall—are interconnected together via this connector. Selected brace members telescope to accommodate increases in wall height and a manually adjustable outrigger screwjack at the remote end of the horizontal member eliminates reliance on prior art deadmen.

  • Patent number: 6994485
    Abstract: A method for mutually connecting at least two elongated elements, such as concrete renforcement rods, by means of a connecting member in the form of a winding spring with a center line, which winding spring is screwed on and around the elongated elements at the connecting place between the two elongated elements by rotation on the center line while expanding by contact with circumferential surfaces of the elongated elements, wherein the selected winding spring is a spiral or screw spiral shaped spring, of which at least one winding has a diameter smaller than the largest transverse dimension at the connecting place, determined by the elongated elements to be connected, which winding spring is placed with its center line at an angle with respect to the elongated elements and is screwingly moved from a thus obtained starting position in the direction of the elongated elements, which screwing movement is continued until at least one winding is diametrically expanded.

  • Publication number: 20040154261
    Abstract: A concrete reinforcing bar connector is described as a resilient clip to hold together two intersecting reinforcing bars, said clip comprising two open longitudinal ‘C’ shaped (grooves), with at least one triangular gusset connecting said ‘C’ shaped faces of said clip, said clip is aligned with said intersecting reinforcing bars and forcibly engaged over said reinforcing bars, said bars configured to intersect at right angles to each other. In one preferred reinforcing bar configuration, the first bar terminates at the second bar, in a second configuration the first bar continues beyond the second bar.

  • Publication number: 20040139683
    Abstract: Column/I-beam interconnect structure including an attaching plate joined to an I-beam end. This plate possesses, along its lateral margins, angularly oriented upper and lower through-passages, each characterized with a reception axis, and designed to receive, along that axis, portions of a hex nut-and-bolt set which is used to clamp together two adjacent, angularly related attaching plates. The socket portions, or outer chambers, of the through-passages are formed with spaced and generally parallel-planar upper and lower surfaces which act in these socket portions to restrain a received hex nut against rotation about its own rotational assembly axis which, in the socket portion, is coincident with the socket portion's reception axis.

  • Patent number: 6758021
    Abstract: A cage spacer for spacing reinforcing rods or welded fabric a specified distance from mold walls for poring concrete during construction projects. The cage spacer comprises two intersection bodies oriented perpendicular to each other and preferable with one body having a base higher than the other. A pair of pads on opposite ends of a first body base for stabilizing the body on the rebar. A pair of rebar engaging clips on opposite ends of the second body base for snapping onto and gripping a perpendicularly intersecting rebar such that the rebar is held securely in the clips. The cage spacer attaches over the intersection of a pair of rebars. At least one apex of the bodies engages a mold wall to keep the mold wall a specified distance from the rebars while concrete is being poured in the mold.
