Described herein is a coupling device, associated parts and a method of use thereof. In one aspect, a coupling device is described comprising a sleeve with an inner surface that encloses at least part of at least one elongated element to be coupled; and at least one deformation means fitted with interference between, and causing local deformation about, at least part of the inner surface of the sleeve and/or an adjacent outer surface of the at least one elongated element. A deformation means insertion tool, a coupling sleeve, a deformation means, and a method of coupling at least one element are also described. The described coupling device, associated parts and a method of use offer the ability to couple together different elements in a strong and/or ductile manner, coupling being tuneable as needed to suit the preferred application. The coupling described may overcome art issues associated with bulky size of coupling, in particular, radial protrusion. The coupling may also increase the coupling force therefore increase the load that may be managed across the coupling device. Further, the way the parts are assembled may minimise generation of localised points of stress therefore also increasing the load that may be managed across the coupling device.

A rebar anchoring system and method are provided. The system includes: a rebar, with an external thread formed on the periphery of at least one end; an anchoring head, with a first perforation and a second perforation disposed respectively at both ends extending axially into the anchoring head and communicating with each other, the inner sides of the first and second perforations being formed respectively with a first internal thread matching with the external thread of the rebar and a second internal thread, and the anchoring head being mounted on the end of the rebar through the first internal thread and the external thread of the rebar; and a bolt, having a screw rod matching with the second internal thread, the screw rod being locked into the second perforation of the anchoring head, and the end of the screw rod pressing against the end of the rebar.

The present invention relating to a rebar coupler that mutually connects and fixes a rebar in a longitudinal direction comprises: a pair of coupler bodies that are formed in a cylindrical shape through which the inside is penetrated, formed of an inlet in one side through which the rebar is inserted, and formed of a fixing piece contact surface inclined toward the inlet inside the penetrated passage; a connecting unit disposed between the pair of coupler bodies to mutually couple the opposite ends of the inlet of each coupler body; a plurality of fixing pieces arranged radially inside the coupler body, wherein an outer surface is installed to contact the fixing piece contact surface, and wherein a plurality of locking protrusions are formed in the horizontal and vertical directions, respectively, to fix the rebar inserted through the inlet; and an elastic member provided inside the coupler body to press the plurality of fixing pieces toward the inlet.

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).

The joint has a prefabricated-reinforced-concrete column, a reinforced-concrete foundation, a column anchoring longitudinal bar, a grouting sleeve and a foundation anchoring steel bar. The foundation anchoring steel bar and the column anchoring longitudinal bar are connected by a seam filling material filling the grouting sleeve. A splicing seam between the reinforced-concrete foundation and the prefabricated-reinforced-concrete column is filled with the seam filling material. The foundation anchoring steel bar includes a vertical portion and a horizontal portion. The vertical portion includes an upper-portion anchoring section protruding out of an upper surface of the reinforced-concrete foundation, a middle-portion non-adhesive section buried within the foundation and a lower-portion anchoring section. An exterior of the middle-portion non-adhesive section is provided with an isolating sheath for isolating the middle-portion non-adhesive section and the concrete adhesion.

A threaded reinforcing bar coupling structure comprises a pair of reinforcing bars and a tubular coupler connecting the pair of reinforcing bars. Each of the reinforcing bars is a deformed reinforcing bar having spiral node portions on an outer periphery of a reinforcing bar main body having a round shaft shape. A cylindrical portion with node portions removed is formed on an end portion of the reinforcing bar, and a male threaded portion is formed on the cylindrical portion. The male threaded portion has hardness or tensile strength greater than that of a remaining portion of the reinforcing bar. The pair of reinforcing bars is connected by the screw tubular coupler that is screwed onto the male threaded portions.
