  • Patent number: 9102130
    Abstract: Structural members having enhanced load bearing capacity per unit mass include a skeleton structure formed from strips of material. Notches may be placed on the strips and a weave of tensile material placed in the notches and woven around the skeleton structure. At least one pair of structural members can be jointed together to provide very strong joints due to a weave patterns of tensile material, such as Kevlar, that distributes stress throughout the structure, preventing stress from concentrating in one area. Methods of manufacturing such structural members include molding material into skeletons of desired cross section using a matrix of molding segments. Total catastrophic failures in composite materials are substantially avoided and the strength to weight ratio of structures can be increased.

  • Patent number: 6089522
    Abstract: The present invention is an improved high chair which positions and supports reinforcement members at a desired distance from a surface. The high chair has a body with a lower base portion, an upper connecting portion and an upper support surface. One or more supporting feet are preferably attached to the lower base portion to provide for secure support of the chair on a variety of surfaces, including harder surfaces such as a concrete mold or softer surfaces such as graded soil. The upper support surface includes a support structure configured to hold the reinforcement bars in a stationary position. The upper support surface also includes a plurality of holes which allows a head piece to be mounted to the chair. The head piece allows the height of the chair to be readily adjusted.

  • Patent number: 5996297
    Abstract: A connector used in forming a composite wall structure that includes two structural layers and an insulative layer. The connector secures the two structural layers together and is insulative so as to minimize the transfer of thermal energy across the insulating layer. The connector is inserted through the insulating layer during manufacturing of the wall structure. The connectors include reinforcement attaching structures for securing reinforcement material in a substantially fixed position before and during formation of the structural layers. The reinforcement attaching structures may be integrally formed on the connector or may be included on a bracket plate that is attached to the main shaft of the connector.

  • Patent number: 5893252
    Abstract: An apparatus for fixating and elevating an interconnected rebar lattice having individual longitudinal and transverse rebar intersections for use as support for poured concrete in highway and other construction. The apparatus including a holding portion having an open ended recess with two opposing walls being generally U-shaped. The recess has a longitudinal axis and is sized and shaped to receive a longitudinal rod. An arc-shaped portion extends laterally outward from each opposing wall and perpendicular to the longitudinal axis of the recess. The arc-shaped portion has a transverse axis and is sized and shaped to receive a longitudinal rod. The arc-shaped portion includes a recess and opposing walls with each wall including a snap-type lock. A locking member has a generally arc-shaped portion and includes a snap-type lock for attaching to the arc-shaped portions and engaging with the snap-type lock of the arc-shaped portions.

  • Patent number: 5699642
    Abstract: A harness system used with steel reinforcement bars or rods to hold them at a desired orientation during and after concrete is poured. The system has two substantially identical harnesses each with its own strap section and a one direction end clasp. A common spacer joins the harnesses together and orients them with respect to each other in different directions. Preferably, the harnesses and spacer are made of a moisture proof plastic material. Two steel reinforcement bars may be oriented in a desired direction--it could be parallel or at right angles to each other--and an appropriate harness system used to hold them in place as concrete is poured over them. One strap of one harness goes around a bar and is put in through its clasp end to a tightened position to hold the bar.

  • Patent number: 5509636
    Abstract: A retainer clip for use with concrete form tie for retention of reinforcing rods has a one-piece body which includes a header, and first and second clips extending angularly therefrom, spaced apart in a first direction, and defining therebetween a generally u-shaped opening sized to slidably receive a reinforcing rod of generally circular cross section. Each of the clips include first and second prongs spaced apart in directions lateral to the first direction, and at least two prongs of the clips further define therebetween a narrow generally rectangular passage which intersects at least a portion of the u-shaped opening, and is sized to receive at least a notched form tie of generally narrow rectangular cross section. The retainer clip secures the reinforcing rod in position substantially against the form tie in a notch to inhibit both relative motion in the first direction and substantial separation therebetween.

  • Patent number: 5181363
    Abstract: A spacer is provided for locating a reinforcing cage or fabric, with respect to a form, when manufacturing reinforced concrete articles such as piping, manhole sections, walls and the like. The spacer is formed from a single length of heavy gauge steel wire, and includes a mounting section which wraps around a longitudinal rod of the reinforcing framework and abuts a transverse rod at its junction with the longitudinal rod. An intermediate section of the spacer extends transversely from the mounting section and is approximately parallel to the transverse rod. A hook at the end of the intermediate section remote from the mounting section is positioned to latchingly engage the transverse rod responsive to elastic deformation of the spacer, thereby to securely maintain the spacer on the reinforcement framework. A spacing loop of a predetermined dimension is provided along the intermediate section.
