A rebar support chair has a housing with first and second opposed boundary walls spaced apart from one another and defining a cavity therebetween, an attachment portion having a seat for supporting rebar, a dampening member, and a force dispersion member inside the cavity. The attachment portion transfers forces between the rebar and housing. The force dispersion member moves in response to vibration of the attachment portion, and movement of the force dispersion member corresponds with compression and decompression of the dampening member. Another rebar support chair has a housing defining a cavity, an attachment portion for supporting rebar, a dampening member, and a force dispersion member in the cavity. The attachment portion transfers forces between the rebar and housing. The force dispersion member moves from a rest position in response to vibration of the attachment portion, and the dampening member biases the force dispersion member toward the rest position.

A collated rebar clinch clip has three components including a pair of spaced U-shaped crimp elements and a U-shaped bridge element connecting the crimp elements. The crimp elements and bridge element are cut from continuous lengths of stock material. A plurality of clinch clips are joined together by a pair of cords to form a collated series of clinch clips that may be arranged in a linear series or spirally wound to form a coil. The tool includes a frame, a die set with a sliding blade and a fixed anvil, an actuator to linearly move the blade relative to the anvil, and a magazine to hold collated clinch clips for sequential delivery between the blade and anvil to tie together a first length of rebar extending through the bridge element and a second orthogonal length of rebar extending through the crimp elements.

A binding device includes: a binding unit configured to bind a binding object with a consumable item; a consumable item accommodation unit configured to accommodate a consumable item to be supplied to the binding unit; a loading consumable item accommodation unit configured to accommodate a consumable item to be loaded into the consumable item accommodation unit; and a loading unit configured to load the consumable item accommodated in the loading consumable item accommodation unit into the consumable item accommodation unit.

Angled coupling including main pass-through coupler to allow first threaded rod to pass therethrough and second coupling extending at angle therefrom to receive second threaded rod. Angled coupling can be used for multiple purposes including, but not limited to, adjusting location of threaded rod, seismic restraints, storm surge restraints and/or providing additional mounting points for support members. Main coupler is configured to be secured to any location on first threaded rod without requiring it to be screwed onto first threaded rod. Main coupler may include first half and second half each traversing length thereof, that can be secured together at desired location on first threaded rod. Main coupler may include upper section having first approximately half of body thereof and corresponding threads and lower section having second approximately half of body (opposite first half) and corresponding threads. Angled coupling is made of high strength material (e.g., steel, cast iron, composites).

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.

A rebar clamp assembly for engaging a rebar rod is provided that includes a clip and a rebar clamp. The clip has a pair of prongs spaced apart from one another, connected by a bridging portion. Each prong of the pair of prongs includes an inner surface. The rebar clamp has a pair of sidewalls hingedly connected at a first end of the rebar clamp. Each sidewall includes a rebar-receiving notch on an inner surface and a plurality of clip-receiving notches disposed proximate a second end of the rebar clamp on an outer surface. The plurality of clip-receiving notches of each sidewall are configured to engage one of the inner surfaces of the pair of prongs of the clip to bring the pair of sidewalls of the rebar clamp together around the rebar rod.

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 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.

A continuous length of material comprising a central straight portion. An arcuate bend is formed at the first end by a downward bend relative to the central straight portion. An eye extends from the arcuate bend with a first end extending from the arcuate bend and a second end formed from an upward bend in the continuous length of material to elevate the second end of the eye above the central straight portion. A locking leg extends from the second end of the eye downward forming a locking hook.
