  • Patent number: 10220503
    Abstract: Concrete which is used in structural support of freeways, bridges, and large buildings, must be tested for anomalies. The testing equipment consists of probes which are inserted into testing tubes. The tubes are placed within rebar cages before concrete is poured. The prior art involved ad hoc methods of tying the tubes to the rebar. The improvement is pre-fabricated, mass produced cylindrical devices which can be axially snapped onto the testing tube. A first cylindrical device also has a perpendicular receptacle which facilitates connection to a second cylindrical device, where the second device can be axially snapped onto a piece of longitudinal rebar on the edge of the rebar cage. The combined first and second devices safely, accurately, and quickly affix the testing tubes to the rebar.

  • Patent number: 9745752
    Abstract: A spacer for spacing the reinforcing cage from the forms used in making concrete products. The spacer of the invention is made from plastic in the shape of a wheel with spokes that join an outer ring with an inner ring that engages a horizontal wire on the wire cage. The rings have gaps to provide for installation of the spacer on a cage wire. The gap in the outer ring is closed by a latch that when properly engaged, will lock the spacer in place on the wire, thus positively holding the spacer on the wire once it is locked in place.

The system may be used, for example, during a concrete pour operation or other construction operation. The system comprises a base spacer and, optionally, one or more of an intermediate spacer and/or another base spacer. The base spacer is constructed to be capable of interlocking with another spacer on each side and the top. The intermediate spacer is constructed to be capable of interlocking with another spacer on each side and both the top and bottom. The interlocks on the spacers may be releasably latched when fully interlocked. By interlocking the spacers, a matrix structure for aligning and supporting conduit or pipe may be created. The base spacer is attachable to a surface, so that the alignment and support system may be fixed in place.

  • Patent number: 8327599
    Abstract: A spacer for positioning rods and wire in concrete is disclosed. In some embodiments, the spacer includes first and second saddle portions joined together via a connection mechanism. Spacing members are joined with the first and second saddle portions and first and second outer edges are joined with the spacing members opposite the first and second saddle portions. A conforming fixed centering tab having a centering groove is joined with the first saddle portion at first and second ends. An adjustable and conforming centering flap is joined with the second saddle portion at a first end via a hinge connection and includes a free second end opposite the first end. The centering flap has a length greater than a width of an opening of the second saddle portion. The connection mechanism is joined with the spacing members adjacent the outer edges for pivoting the first and second saddle portions.

  • Patent number: 8322108
    Abstract: A chair for supporting and spacing post-tension cables having a generally tapered body with an upper receiving area for securing the cables and a planar base adapted to rest on a flat support surface. The body has inner and outer surfaces that are substantially complementary to one another to allow a plurality of chairs to be stacked together. The receiving area includes posts extending upwardly between notches. The posts define passageways for guiding the cables into the notches. Detents project inwardly from the tops of the posts and fixedly retain the bars within the passageways. The chair may be formed from a resilient polymeric material.

  • Publication number: 20120247057
    Abstract: Structures for supporting and aligning a reinforcing bar (“rebar”) during the construction of a column, beam or other structure in which the rebar is laid out in parallel to an axis. One such structure includes a support structure having a square ring, where the corners of the square ring include a rebar receptacle configured to receive a reinforcing bar. The rebar receptacle includes an opening through which the reinforcing bar can be inserted, where the opening is configured to allow the reinforcing bar to enter the rebar receptacle and further configured to retain the reinforcing bar after the reinforcing bar has been seated due to the width of the opening being less than a diameter of the reinforcing bar.

  • Publication number: 20120233956
    Abstract: A rebar attachment device includes a vertical attachment device having a base member that includes a bottom surface for making contact with a piling, and a top surface for positioning a sleeve and a pair of flexible chairs. Each of the chairs acts to removably engage and position a rebar rod at a predetermined separation distance from the base member. A rebar attachment system includes at least one vertical rebar attachment device, at least one horizontal rebar attachment device, a tether for positioning the at least one vertical device onto a piling, and a tether connector for securing the tether to the piling.

  • Publication number: 20120200004
    Abstract: This invention refers to a weight-lightening disc for making light reinforced concrete structures such as slabs, prefabricated slabs, foundation slabs, partition walls and beams; to a mesh, specifically designed for this invention and to the construction method to make such structures. The method allows manufacturing the components that make it possible to construct buildings with light reinforced concrete structures. The field of application of the invention is construction in general, such as houses, buildings and bridges. The invention provides a solution to the problem of lightening of the structures, including a construction method that comprises a set of weight-lightening discs in combination with electro-welded meshes (specially designed for the each specific thickness of the slab) and the hooks that hold together the meshes. The compound of elements and the method allow lightening minimum-thickness slabs.
