A binding structure for attaching two structures to each other, said binding structure comprising an elongated body portion having a first end portion and a second end portion. A head portion is provided in the first end portion and in the second end portion, wherein said head portion protrudes radially from (at least a portion of) the body portion.

Connector for connecting rebar intersections of a foldable FRP rebar cage includes two channels for receiving the intersecting FRP rebar. One channel has a spherical member and the other has arms shaped to hold the spherical member, to allow the connected rebar to rotate in the X, Y and Z axes.

An angled coupling including a main pass-through coupler to allow a first threaded rod to pass therethrough and a second coupling extending at angle therefrom to receive second threaded rod. The main coupler is configured to be secured to any location on the first threaded rod without requiring it to be screwed onto first threaded rod. The main coupler includes a first half and a second half spaced from each other that can be secured together at desired location on first threaded rod. The main coupler includes an upper section having a first approximately half of body thereof and corresponding threads and lower section having a second approximately half of body, opposite the first half, and corresponding threads. The first threaded rod is retained in both halves by insertion and rotation until the threaded rod snaps in place and kept fixed with retaining clips.

A device may include an anchor point operationally connected to a rebar, an E-clamp coupled to the anchor point, and a forcing handle configured to tighten the E-clamp to the rebar.

Rebar-based support assemblies that can be fabricated without the need for on-site welding. The assemblies include a number of differing sized and shaped crimps used in place of welds to provide rebar assembly-to-rebar assembly connections. Each crimp mechanically couples two or three pieces of rebar together, such as a border bar of one rebar assembly to a border bar of an adjacent rebar assembly. Each crimp includes a body with two or more arcuate recessed surfaces each for receiving a piece of rebar. In a first configuration of the crimp, a pair of spaced-apart arms (or extending members) extend from the body and define an opening through which the rebar is passed and set into the recessed surfaces. A deformation force is applied upon the two arms to deform the body into a second configuration with the arms in abutting contact or nearly so at an outer tip or end.

A clip applying apparatus is provided for connecting plastic clips to reinforcing bars. The clip applying apparatus will generally include a barrel, a hammer received in the barrel, and a main drive configured to reciprocate the hammer within the barrel. Other features may include a safety shield as well as a lockout lever which prevents proximal movement of the safety shield if a clip is not fully received within the barrel. Another feature which may be included is a clip door operably connected to a sliding-pivot channel defined in one of the barrel and the clip door. Still other features may include at least one guide slot disposed within the barrel to direct hammer movement, and a hammer bushing coaxial with the barrel to support the hammer.

The present invention is a clip for securing more than two rebar rods. The rods may be secured in a planar or three-dimensional lattice configuration. In a planar configuration, the clip accommodates two parallel rebar rods and a third rod perpendicular to the first two. Alternatively, the clip may secure three mutually perpendicular rods. The clip is constructed of at least two mutually perpendicular planar surfaces. Each planar surface is recessed in a seat for holding a rod. Each seat has a semicircular arch where the rod sits, with an optional rectangular opening for inserting the rod. In a preferred embodiment, the clip has five seats. Two seats are parallel with a coincident axis in the x-direction. Two other seats are side-by-side with parallel axes in the y-direction. Another seat has an axis in the z-direction. Each rod is held in place by other rods.

An anchor includes a body having a first end and a second end; the body having a side wall between the first end and the second end; the body including an axial hole extending from the first end into the body, the axial hole for receiving an end portion of a rod; and the body including a first longitudinal cutout extending into the side wall to create a first opening into a first portion of the axial hole to expose an end portion of the rod to be inserted in the axial hole to be welded to the body.

An angled coupling to receive multiple pieces of threaded rod in order to adjust the location of the threaded rod, that can also be used for seismic restraints and/or storm surge restraints. The angled coupling includes a first internally threaded coupler and a second internally threaded coupler connected to the first coupler and extending from the first coupler at a defined angle from an axis thereof. The angled coupling may include additional couplings extending from the first coupler at the defined angle that may be spaced apart around the axis of the first coupling. The first coupler may be a passthrough coupler to either have a threaded rod pass therethrough or to receive a first threaded rod in a first side and a second threaded rod in a second side. The angled coupling is made of a high strength material (e.g., steel, cast iron, composites, high strength plastics, combinations thereof).

A system includes a form panel positioning apparatus for positioning an elevated form panel of a concrete form. The apparatus may include at least one positioning subassembly providing positioning of the form panel in at least one direction, and may include a first positioning subassembly with a first clip to clip onto an element of a concrete reinforcement structure, a first support rod engageable with the first clip, and a first positioning plate positionable on the rod adjacent to the form panel to support the form panel on the rod. The system may include a second positioning subassembly for positioning the form panel such that the form panel is supported in two directions, such as substantially vertical and substantially horizontal directions.
