A clipping apparatus for holding rebar is disclosed. The clipping apparatus includes having a first base portion and a second base portion. Extensions and clips are positioned in the base portions to hold one or more rebar rods or wires in a stable orientation. Platforms are positioned to give a user a plane upon which to apply an engaging force to clip the rebar into the clipping apparatus. A chair arrangement is positioned to provide spacing between adjacent planes of rebar. A fluid-stop section is positioned about the first base portion and the second base portion. The fluid-stop section also includes a raised rim. Together with the base, platforms, and chair, the fluid-stop section to help prevent flow of liquid through the clipping apparatus.

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 handheld tool for installing wire on a fence, the tool having a frame, a sprocket system that is situated at least partially within the frame and engaged by an actuator, a T-post alignment unit that is configured to position a vertical T-post against the tool, a clip storage magazine that is attached to a top of the frame, a tube assembly that is movably mounted within the frame, and a presenter that is configured to present clips from the magazine. The sprocket system and tube assembly are configured to cause the clip presented by the presenter to be pushed into position against the T-post and a horizontal fence wire, tension the fence wire against the T-post, lock the fence wire into position against the T-post by straddling the T-post with the clip, and wrap two ends of the clip around the fence wire to attach it to the T-post.

A V-shaped tie hoop assembly enhances field construction performance by integrally forming a plurality of V-shaped tie hoops after constituting the plurality of V-shaped tie hoops in a bundle form, maintains intervals, and enhances reinforcement performance. The V-shaped tie hoop assembly can includes: a plurality of V-shaped tie hoops, each of which has a bending part at the center thereof and anchor parts extending to opposite sides of the bending part, and disposed at different heights at an interval; and a vertical support bar connecting all of the V-shaped tie hoops to integrally couple the V-shaped tie hoops.

The present invention relates to a V-shaped tie reinforcement for reinforcing a hoop reinforcement installed around a main reinforcement, wherein the V-shaped tie reinforcement is installed in order to prevent deformation, such as buckling, of the main reinforcement installed on a long member of an RC structure or an SRC structure, such as a column or a compression beam while preventing brittle fracturing of concrete. The present invention comprises: a V-shaped reinforcement composed of a bent part having a shape surrounding a main reinforcement at the center thereof and an anchor part open at both sides; and a fixing means composed of an upper tie reinforcement fixing brace fixedly installed at the V-shaped reinforcement and connected to the main reinforcement, and a rotation preventing brace fixedly installed at the bent part of the V-shaped reinforcement and preventing the V-shaped reinforcement connected to the main reinforcement from rotating upward and downward and right and left.

A rebar spacer installed in a rebar crossing portion includes a spacer body and a pair of installation metal fittings. The spacer body includes a main portion and a pair of leg portions integrally formed with the main portion. The pair of leg portions is protrudingly provided with an interval on a rebar-side surface of the main portion. The interval between the pair of leg portions is equal to or larger than a diameter of the rebar and a depth of the pair of leg portions in an installation direction is equal to or less than the diameter of the rebar. Each one of the pair of installation metal fittings has a structure such that one end portion is locked into one of the pair of leg portions and the other end portion is hooked on a back-side rebar.

The sprocket system and tube assembly are configured to cause the clip presented by the presenter to be pushed into position against the T-post and a horizontal fence wire, tension the fence wire against the T-post, lock the fence wire into position against the T-post by straddling the T-post with the clip, and wrap two ends of the clip around the fence wire to attach it to the T-post.

A key-locked rebar clamping assembly includes a clamp that may be forced onto the perpendicular intersection of the upper and lower rods of crossed rebar and then held from below with a key. The assembly is readily installed by forcing the clamp over the intersection of the upper and lower rods and forcing the key through a keyway in opposing sides of the clamp. The assembly holds the rods together with the clamp at the top and the key at the bottom regardless of force, vibration, and the like applied to either rod. As the key constrains downward movement of the lower rod away from the clamp and the upper rod, the lower rod will not separate from the upper rod if walked on. The assembly reduces the need to alternate longitudinal adjacent rods between upper and lower positions, thus saving labor costs through the elimination of wire tying and complicated positioning.

A bracket for locating a vertical reinforcement bar within a block wall having a central area to enable a reinforcement bar placed vertically through a void of a block wall to pass through the bracket; and a locator for locating the central area in a predetermined position within the void of a block wall; wherein one or more guides extend into the central area to guide one or more reinforcement bars through a central aperture, the central aperture defined by the one or more guides.
