In a screw-coupling structure between an internally-threaded body and an externally-threaded body, for connecting reinforcing bars: the internally-threaded body includes, on the inner diameter thereof, a parallel-tapered-integrated internal thread section formed by integrating a parallel internal thread section formed as a parallel screw thread, with a tapered internal thread section formed on one end of the parallel internal thread section so that the minor diameter thereof gradually narrows; and the externally-threaded body comprises, on the outer diameter thereof, a parallel-tapered-integrated external thread section formed by integrating a parallel external thread section formed as a parallel screw thread, with a tapered external thread section formed on one end of the parallel external thread section so that the major diameter thereof gradually narrows.

A composite tubular structure includes an elongate composite member having an inwardly tapered section at an end and an embedded nut retained in the end inwardly tapered section for forming a connection with another component. The inwardly tapered section has an inner surface which follows a tapered outer surface of the embedded nut, the inwardly tapered section narrowing the composite member in a longitudinal direction towards the end so as to provide a constriction which retains the embedded nut within the inwardly tapered section. The embedded nut comprises a multipart nut, comprising an internal nut and an internal support member, and wherein the internal nut is arranged to slide within the internal support member in a direction away from the end of, and into, the elongate composite member when the composite tubular structure is under conditions of excessive axial compressive load.

A wall mounting bracket for mounting a channel profile element to a wall surface includes a wall plate to be mounted to the wall surface, and at least one support for supporting an end portion of the channel profile element. The support is attached to and extends from the wall plate, The support includes at least one wall portion having fastening apertures. The support includes at least a first support profile and a second support profile. In use the first support profile bears against an exterior side of one of the opposing walls of the channel profile element and the second support profile bears against an interior side of the other one of the opposing walls of the channel profile element.

A unitary steel bracket has an arced portion and a hanger appendage extending perpendicularly from a convex perimeter of the arced portion. The arced portion has two opposed planar surfaces with parallel mount holes through each end. The hanger appendage has two opposed planar surfaces coplanar with the arced portion planar surfaces. A portion of the hanger appendage is bent at a 90-degree angle and has a support mount hole perpendicular to the parallel mount holes. the bracket is prefabricated to a predetermined bracket size corresponding to a predetermined pipe flange size. A method of hanging joined flanged includes providing the bracket; aligning the parallel mount holes with holes on a pipe flange; inserting connection bolts through the holes; threading nuts onto the bolts to a predetermined torque; and attaching the support mount hole to a building structure.

A metallic-composite joint fitting is provided. The fitting may comprise a frustoconical internal bearing having a bore, a conical sleeve configured to be disposed about the frustoconical internal bearing, a composite structure configured to couple between the frustoconical internal bearing and the conical sleeve, a metallic end fitting configured to be disposed within the bore and couple to the frustoconical internal bearing, and an external nut configured to couple to the metallic end fitting and the conical sleeve, wherein at least one of the frustoconical internal bearing or the conical sleeve comprises a flanged portion mutually configured to couple the conical sleeve to the frustoconical internal bearing via a locking ring.

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.

An indicator assembly includes a fastener defining a first end, a second end opposite the first end, and an axis extending from the first end to the second end; a first indicator positioned radially outwardly of the fastener relative to the axis of the fastener; and a second indicator positioned radially outwardly of the fastener relative to the axis of the fastener, wherein the second indicator is axially in between the first indicator and the second end of the fastener upon the fastener being oriented in a first position, and wherein the second indicator is radially inwardly or radially outwardly of the first indicator upon the fastener being oriented in a second position.

A fitting assembly includes an indicator assembly that provides a visual indication of torque value to verify when the desired operational torque value is achieved. The fitting assembly includes a nut, and a visual indicator assembly positioned on the nut which has a plurality of visual indicators that provide a visual indication of a torque level being applied. A sleeve is attached to the nut and includes a window through which a portion of the visual indicators is visible based on the torque level being applied. A resilient member couples the sleeve to the nut. As the nut is rotated to apply torque to the nut, the resilient member biases the sleeve in a fixed position and the nut rotates relative to the sleeve, whereby the visual indicator assembly rotates relative to the sleeve to alter which portion of the visual indicator assembly is visible through the window to provide a visual indication of when the operational torque level is being applied. The fitting assembly includes a positive locking feature that interacts with a serrated portion of a nipple fluid connection to positively lock a position of the nut to prevent nut loosening.
