A sheathing repair assembly for a tension member of a post-tensioning tendon, the tension member including a strand and a sheathing layer is disclosed. The sheathing repair assembly includes a repair tube having first and second end portions and a first sealing assembly. The first sealing assembly includes a first nut having a first frustoconical surface and a first forcing element adapted to cooperate with the first frustoconical surface so as to compress the first end portion of the repair tube. The sheathing repair assembly also includes a second sealing assembly having a second nut having a second frustoconical surface and a second forcing element adapted to cooperate with the second frustoconical surface so as to compress the second end portion of the repair tube.

The hybrid post-installed anchor for concrete is a structural anchor for installation within a hole formed in concrete. The hybrid post-installed anchor for concrete includes an anchor rod and a plurality of anchor rings mounted on and encircling the anchor rod. Each anchor ring includes a cylindrical ring, having opposed open upper and lower ends, and a plurality of fins secured to an outer surface of the cylindrical ring. Each fin has a fixed edge, which is secured to the outer surface of the cylindrical ring, and a free edge. Each fin projects radially and upwardly, such that each fin is angled with respect to a common central axis of the anchor rod and each anchor ring when the anchor rings are mounted coaxially on the anchor rod. Alternatively, the fins may be formed integrally on the anchor rod, without separate cylindrical rings.

A corner hardware kit for completing a frame corner that is defined by a first frame element and a second frame element includes a corner bracket having a first portion for attachment to the first frame element and a second portion for attachment to the second frame element. The corner bracket has an upstanding foot that protrudes rearwardly therefrom and carries a coupling member at a distal end thereof. The kit also includes an elastic corner insert that has a curved outer surface and has a pair of first coupling elements for mating to a pair of second coupling elements that are associated with the first and second frame elements to complete the corner of the frame.

A modular wall overlay system for installation on a support surface includes a frame; and a cover securely retained on the frame by a tensioning system whereby the cover is free of direct attachment to the frame but rather is retained under tension on the frame by the tensioning system. The frame includes a plurality of frame pieces and a plurality of corner brackets. The frame pieces are directly coupled to respective corner brackets but are free of direct coupling to one another.

A modular wall overlay system for installation on a support surface includes a frame; a cover that is securely, yet detachably, retained on and along a front face of the frame by a tensioning mechanism that is configured to tension the cover; and elastic corner inserts that are disposed in corners of the frame and include curved outer surfaces that are configured to permit the cover to be stretched over the elastic corner inserts creating radiused corners and preventing tearing of the cover in corners thereof when the cover is tensioned by the tensioning mechanism.

A modular wall overlay system for installation on a support surface includes an outer frame having a pair of opposing ends and a pair of opposing sides and a customizable inner frame that is coupled to the outer frame. The inner frame includes a plurality of transverse supports that extend between the opposing sides and a plurality of longitudinal supports that extend between the opposing ends. The longitudinal supports and the transverse supports lie in a common plane defined within the outer frame. The system further includes a cover that is securely retained on the outer frame.

A corner hardware kit for completing a frame corner that is defined by a first frame element and a second frame element includes a corner bracket having a first portion for attachment to the first frame element and a second portion for attachment to the second frame element. The corner bracket has an upstanding foot that protrudes rearwardly therefrom and carries a coupling member at a distal end thereof. The kit also includes an elastic corner insert that has a curved outer surface and has a pair of first coupling elements for mating to a pair of second coupling elements that are associated with the first and second frame elements to complete the corner of the frame.

A concrete anchor capable of resisting large loads while requiring minimal embedment depth. The system includes a concrete structure including a cylindrical opening in the concrete surface thereof. The system also uses an anchor which includes a sleeve and a plug. The sleeve includes at least two legs extending toward a first end of the sleeve. The plug includes an increasing diameter portion disposed toward a first end of the plug. The plug includes a locking opening. After installation, legs of the sleeve extend radially outward past the wall and the increasing diameter portion prevents inward movement of the legs to lock the sleeve and the plug in turn in the concrete cylindrical opening. Furthermore, dynamic loading on the plug via the locking opening when the anchor is in use generates a dynamic radially outward force on the legs to secure the anchor in the concrete hole.

A joint includes a solid rod having a slit or opening into which a wedge is inserted. The rod and wedge are inserted into a fitting. The internal surface of the fitting has a contour which continuously and nonlinearly varies with distance along the fitting. The wedge has a dimension having a similar contour. The shape of the contour can be described by a polynomial of order two or higher.

A corrosion-protected tension member (10) comprises a plurality of tension elements (14) and an anchor device (44) with an anchor element (16) which is designed to transmit tension forces from the tension elements (14) to a superior structure (12), at least one elastically compressible sealing disc (28), and a supporting device (26) which is arranged on that side of the at least one sealing disc (28) which faces away from the anchor element (16). According to the invention, when the tension member (10) is in a state in which it is preassembled but not yet placed under tensile stress, at least one plastically deformable disc (30) of corrosion protection material is arranged between the anchor element (16) and the at least one sealing disc (28).
