A system and method for applying tension to a reinforcement member is provided. The system includes a gripping device, a tension device, and a tension application sub-system. The gripping device includes first and second attachments. Each attachment retains a respective end of the reinforcement member with sufficient friction force based on a predetermined tension to be applied to the reinforcement member. The tension device includes first and second tension tubes configured to removably receive and hold the first and second attachments, respectively. The tension application sub-system has first and second tension application apparatuses and first and second coupling devices. The first and second coupling devices couple the first and second tension tubes to the first and second tension application apparatuses, respectively. At least one of the first and second tension application apparatuses creates and controllably adjusts a tension load within the reinforcement member.

A system and method for allowing components to attach to a pre-cast pre-stressed concrete structure is provided. The system includes a first attachment part and a second attachment part. The first attachment part has a first body. The first body has a first concrete structure facing side and a first plurality of attachment members extending from the concrete structure facing side. The second attachment part has a second body. The second body has a second concrete structure facing side and a second plurality of attachment members extending from the concrete structure facing side. The first and second attachment parts are spaced apart forming a compressible junction therebetween. The pre-cast, pre-stressed concrete structure is formed from uncured cement, at least of a portion of the first and second attachment members being embedded in the pre-cast, pre-stressed concrete structure.

System and method allows a component to attach to a pre-cast, pre-stressed concrete structure. The system includes a first attachment part, a pre-cast, pre-stressed concrete member and first and second reinforcing members. A first body of a first attachment part has a first concrete structure facing side and a first plurality of attachment members. The pre-cast, pre-stressed concrete member is formed from uncured cement. At least a portion of the attachment members are embedded within the pre-cast, pre-stressed concrete member. The first reinforcing member is placed under a first tension load and the second reinforcing member is placed under a second tension load. The pre-cast, pre-stressed concrete member is formed from uncured cement poured about at least a portion of the first and second reinforcing members while the first and second reinforcing members are under stress.

A reinforcing bar, and a method of producing a reinforcing bar, are provided. The reinforcing bar includes a plurality of strands and a deformity pattern. Each strand includes a plurality of carbon fibers. The strands having been impregnated with a resin and twisted forming a unified structure. The deformity pattern being formed within the unified structure by twisting the strands a predetermined number of times per linear foot of the unified structure and allowing the resin-impregnated unified structure to cure.

A securement device having a rod receiver attachable to the end of an anchor rod, the securement device having a headless nail slidably extendable from a first position within the device to a second position protruding outwardly from the end of the securement device opposite the rod receiver, and a method of positioning and securing an anchor rod attached to the securement device in a desired location on a concrete form deck within a rebar structure for a concrete formation, so that the headless nails may release from the securement device body when the deck is removed after the concrete sets, leaving an innocuous nail void in the concrete that may serve as a functional attachment recess.

A base member for cooperating with a support member and at least one fixing member to form an anchor assembly mountable to a form board on which wet concrete may be poured during formation of a concrete substrate. The base member includes: a mounting portion for positioning the anchor assembly on the form board prior to inserting the fixing members into the form board; an aperture having first and second generally opposed ends, the first end being open to facilitate insertion of the support member into the aperture; and a barrier reconfigurable in use from a first configuration, in which the barrier restricts ingress of wet concrete into contact with the support member via the second end of the aperture, to a second configuration in which the barrier allows an object to extend via the second end of the aperture into contact with the support member.

An apparatus wherein a sill member or anchored member is connected to a concrete foundation or anchoring member by a connector, the connector having an embedment member and an attachment member connected to the upper end of the embedment member and extending away from the embedment member. The connector attaches to the side of sill member with fasteners.

Concrete coupling assembly comprises a base holder for being attached to a concrete forming surface, the base holder including a central opening; a coupler having one end disposed within the central opening, the coupler having an axis for being positioned substantially transverse to the forming surface, the coupler having first and second threaded bores through the one end for attachment of a threaded rod; and a separate anchor body threadedly attached to another end of the coupler.

An anchor device for a floor, the anchor device comprising an article securing arrangement to which an article can be secured. The article has a moveable securing mechanism. The article securing arrangement defines a cavity to receive the moveable securing mechanism, and the article securing arrangement includes a co-operating means to co-operate with the moveable securing mechanism in the cavity and secure the article to the anchor device. The anchor device has a height which is no more than 30 mm.
