A sealing connector cover for a tendon in an encapsulated post-tensioning reinforcement system includes a plurality of circumferential cover segments each comprising a circumferential part of a female connector housing at one longitudinal end, and a male connector housing at another longitudinal end. Each segment has a locking element to engage a corresponding locking element on a longitudinally corresponding segment. Each circumferential segment comprises a circumferential part of a locking element in the female connector housing configured to engage the male connector housing of a longitudinally adjacent sealing connector cover or a connector on an encapsulated anchor.

The invention relates to a system for joining two components or for reinforcing a component, comprising a first and a second threaded sleeve which each comprise the following: an outer thread, with the aid of which the threaded sleeve can be screwed into the respective component and which is suitable to form a composite with the respective component, and a power drive, by which a torque for screwing the threaded sleeve into the respective component can be transmitted to the threaded sleeve. The system further comprises an elongate clamping element which is suitable to be guided through the second threaded sleeve and introduced into or guided through the first threaded sleeve, and which is suitable to axially clamp the first and the second threaded sleeve in such a manner that the first and the second threaded sleeve form opposed composite stresses in the respective component.

An exemplary method of indicating a condition of grout within a post-tensioned tendon involves positioning a magnet and a metallic sensing plate in close proximity to an outer surface of the post-tensioned tendon; rotating the magnet and the metallic sensing plate around the outer surface of the post-tensioned tendon; measuring an amount of magnetic forces applied to the magnet during rotation of the magnet around the post-tensioned tendon; measuring an impedance between the metallic sensing plate and metallic strands within the post-tensioned tendon during rotation of the metallic sensing plate around the post-tensioned tendon; and generating an image of a cross-section of the post-tensioned tendon indicating one or more grout conditions in spatial proximity to the metallic strands within the post-tensioned tendon based on measurement data using the magnet and the metallic sensing plate.

A method is defined for attaching mounted parts on a mounting substrate, formed of concrete or masonry, having a group of anchors, wherein the following is true for the ratio VSd/NSd of the rated value for the transverse load VSd and of the rated value of the tensile load NSd of at least one anchor in the anchor group: VSd/NSd≥0.3, preferably VSd/NSd≥0.6 and particularly preferably VSd/NSd≥1.0, and wherein the characteristic resistances of these anchors to transverse loading VRk or to tensile loading NRk satisfy the following relationship: VRk/NRk≤1.1. The at least one anchor of the anchor group is inclined at an angle αAnker to the perpendicular to the surface of the mounting substrate in such a manner that the following is true: αAnker=k*¾*arctan (VSd/NSd) for NSd>0, and αAnker=k*67.5° for NSd=0, where: 0.8≤k≤1.34, providing that αAnker≤75°.

A cellulose-based structural building panel assembly includes a cross-laminated timber (CLT) core which is reinforced with one or more post-tensioned tendons stressed to a pre-selected tensioning force, following the placement as part of the panel assembly. The tendons are provided within a sleeve which is grouted with a channel formed in an underside of the core and which after post-tensioning of tendons is infilled with a binder securing the tendons in a fully bonded configuration.
