A coupler may include a first chuck, the first chuck including an outer surface and first external threads and a second chuck, the second chuck including an outer surface and second external threads having a reverse orientation relative to the first external threads. The coupler may also include a coupler body including a first end, a second end, and a passageway extending between the first end and the second end, the first end secured to the first chuck, the second end secured to the second chuck, the first end including first internal threads engaging the first external threads, the second end including second internal threads engaging the second external threads.

A rebar positioning device with opposite ends for positioning adjacent to a form face of at least one form panel may include a support rod having opposite ends and an outer surface, with at least a portion of the outer surface being threaded. At least one bar clip may be movably mounted on the support rod. An orientation of the at least one bar clip on the support rod is adjustable, and a position of the at least one bar clip on the support rod is adjustable.

A buckling resistant spring clad bar (BRSCB) assembly is described. The BRSCB assembly includes a plurality of bars arranged to form a perimeter, each of the plurality of bars having a top end and a bottom end. A plurality of springs are provided, wherein at least one of the plurality of springs is wrapped around each of the plurality of bars. A diameter of the at least one of the plurality of spring is greater than a diameter of the each of the plurality of bars. The at least one of the plurality of springs is wrapped around each of the plurality of bars in close contact to provide buckling resistance against a load applied over each of the plurality of bars.

A protective cap to cover impalement hazards, by means of increasing the surface area associated with said hazard may include utilizing a metal plate embedded within a plastic/polymer cap, with a flat top and a receiving shaft housing below, with mechanical means of securing the cap to said hazard with a mechanical plunger. The mechanical plunger is driven from the exterior of the housing by means of rotating a threaded shaft to selectively engage the impalement hazard and compressively hold the protective cap to the impalement hazard.

A safety cap is to be used on linear members to provide a greater surface area on the end of the linear members. The cap has a platform and an attachment portion that is coupled to the platform. The attachment portion has two or more engagement members and two or more joint portions. Each joint portion couples two of the two or more engagement members together, and the two or more engagement members extend inward from the two or more joint portions.

A structural rod protective device for preventing injury to persons falling on structural rods includes a first panel. Each of a pair of second panels is coupled to and extends perpendicularly from a respective opposing edge of the first panel to define a channel. Each of a plurality of slats is coupled to and extends between the second panels. The plurality of slats defines a plurality of slots. The second panels are configured to selectively position over linear and nonlinear rows of structural support rods, such as rebar. Each rod is inserted into a respective slot so that an end of the rod abuts the first panel. Persons falling on the rods are protected from impalement upon the rods.

A method for forming a concrete anchor may comprise the steps of providing an anchor body, at least partially encapsulating the anchor body in a sealing cover, providing at least one tubular member, engaging an end surface of the tubular member against a surface of the sealing cover so as to weld the member to the sealing cover.

An example embodiment of the present invention provides a pole cap for covering an end of a pole. The pole cap comprises a sheet that includes a central portion, a first strip, and a flap that has a slit. The central portion is configured to cover a base surface of an end of a pole. The first strip is configured to fold over an edge of the base surface and circumferentially wrap around a portion of a curved surface of the pole. The flap is configured to fold over the edge of the base surface.

A structural rod protective device for preventing injury to persons falling on structural rods includes a first panel. Each of a pair of second panels is coupled to and extends perpendicularly from a respective opposing edge of the first panel to define a channel. Each of a plurality of slats is coupled to and extends between the second panels. The plurality of slats defines a plurality of slots. The second panels are configured to selectively position over linear and nonlinear rows of structural support rods, such as rebar. Each rod is inserted into a respective slot so that an end of the rod abuts the first panel. Persons falling on the rods are protected from impalement upon the rods.

A system, method, and apparatus for post-tensioning in masonry-based system, especially concrete support systems. In one embodiment, a system is presented that can include an anchor, pocket-former, and bolt, wherein the pocket-former can be configured to engage each of the anchor and bolt to facilitate securing of the system to a form. In another embodiment, a method of post-tensioning is presented, wherein a tendon can be suspended at the live end via connections facilitated by a pocket-former. In another embodiment, a system and method of post-tensioning is presented that prevents a pocket and anchor from being contaminated with debris that could ultimately compromise the integrity of the tensioned material.
