摘要： In a management system for an attachment state of an attachment object, a sensor capable of detecting a value equivalent to stress of stress loaded, or a predetermined value from which the value equivalent to stress can be calculated, a washer storage unit storing identification information of a sensing washer, and a washer control unit transmitting the value equivalent to stress and the identification information of the sensing washer via a communication unit, are provided in the sensing washer between a bolt and a nut that attach an attachment object to a structural object. A management processing device acquires the value equivalent to stress and identification information of the sensing washer transmitted from the sensing washer, and presents the value equivalent to stress of the sensing washer of the identification information, or a corresponding stress value, as relational information with respect to a reference value stored in a storage unit.

摘要： Disclosed is a fastener assembly comprising: a bolt member, comprising a bolt head and a shank, at least a part of which is screw threaded; a nut member for threaded engagement with the shank; a first drive element allocated to the bolt member and a second drive element allocated to the nut member, each drive element comprising a body and adapted for engagement by a corresponding tool. The body of the first drive element is joined to the bolt member by a first interposed interlayer structure. The body of the second drive element is joined to the nut member by a second interposed interlayer structure. The first interlayer structure is adapted to fracture in response to relative rotational and/or tensile force applied to the first drive element. The second interlayer structure is adapted to fracture in response to relative rotational and/or tensile force applied to the second drive element.

摘要： A compound screw is a two-piece assembly where the head of the screw can rotate in the tightening direction to a designed tightening torque to drive the screw while being able to positively counter-rotate in the loosening direction. The screw assembly comprises a screw and a cap surrounding the head of the screw. The screw has a head at the top and a threaded shank downwardly extending from a base of the screw head. The screw is turned by turning the cap about a central axis of the screw. The cap is rotatably affixed to the screw head by a loose riveting of the cap to the top most end of the screw head by flaring a thin-walled upwardly extending portion thereof. The cap includes a plurality of axially extending peripheral resilient arms which engage peripheral cam surfaces around the outside of the screw head.

摘要： A resilient washer has a one-piece washer body. The washer body has a central opening, an upper fastener interfacing section or bowl, a lower structure interfacing section or bowl and a resilient middle portion. The resilient middle portion connects the upper fastener interfacing section or bowl and the lower structure interfacing section or bowl. The resilient middle portion is configured to be locally collapsed when a fastener in the central opening is tightened into a structure. In one embodiment, the upper fastener interfacing section or bowl is annular, wherein the upper fastener interfacing section or bowl has a concavity for holding a head of the fastener. The concavity can be of a hemispherical shape. Preferably, the concavity has a smooth surface to allow polyaxial movement of a fastener.

摘要： A system for remotely retrieving sensed conditions at one or more building components. The building components are remote or numerous so that a wireless collection of the sensed conditions provides a significant benefit to a builder or building operator. A remote transceiver sends a wireless signal to a building component. The building component includes an onboard transceiver. At least some of the energy from the transmitted wireless signal is received by the onboard transceiver, sent to a storage device, and stored therein. The stored energy is used to operate a sensor for sensing an onboard condition. The onboard condition is then wirelessly transmitted by the onboard transceiver back to the remote transceiver to be displayed.

摘要： A fastening element (10) comprising a screw (1) with a screw head (11) and a sleeve-shaped rivet arrangement (2) through which the screw (1) passes. Starting from the screw head, the rivet arrangement (2) has an installation spacer region (21), a deformation region (22) and a drive region (23) into which the screw is screwed. Seen from the drive region (23) to the screw head, the circumferential boundaries of the drive region (23) lie within the boundaries of the deformation region (22), the boundaries of the installation spacer region (21) protrude radially over the boundaries of the deformation region (22), and the boundaries of the screw head protrude radially over the boundaries of the installation spacer region (21). The installation spacer region (21) and the deformation region (22) are designed in such a manner that, as the screw is tightened, first of all plastic deformation of the deformation region (22) occurs.

摘要： A device for torque limiting, which includes a nut and a holding element including a top part having an entrainment profile in a rear area for the rotatably fixed coupling of the top part with a setting tool. A receiving part has a receptacle in a front area of the holding element, in which the nut is rotatably fixedly accommodated. A device for torque transmission from the top part to the receiving part connects the top part and the receiving part and breaks at a limiting torque, interrupting the connection between the top part and the receiving part. The holding element includes at least one holding claw situated on the receiving part and securing the nut in the receptacle on the front side of the nut. A fastening arrangement made up of an expansion anchor and a device of this type for torque limiting as well as a method for manufacturing a device of this type.
