In the present invention, a through-hole (2) and a compression periphery part (3a) at which the core of the resin foam (1c) is compressed are provided in a fastening part of a resin-foam core composite plate (1). A cylindrical part (11a) of a metallic fastening member (11) is inserted into the through-hole (2) from the proximal end side of a wall part (4). The fastening member (11) is crimped to the distal end of the wall part (4) via an eyelet member (12) placed on the outside of the wall part (4) so as to forcibly spread the cylindrical part (11a). The fastening member (11) and a counterpart member (A) are fastened together by tightening a nut (14) onto a bolt (13) inserted into the cylindrical part (11a).

In order to provide an anchor element for fastening an article to a further article, this anchor element being simple and inexpensive to produce and enabling an article to be fastened to a further article simply and reliably, it is proposed that the anchor element should include a base body that takes a hollow form, at least in certain regions, and surrounds a receiving space for receiving a fastening element, wherein the base body includes one or more elastically yielding spring elements that are formed by one or more wall portions of the base body, and these project into the receiving space in an installed condition of the anchor element.

A device for joining material by anchoring an insert comprising a first material in a structure comprising a second material is provided. The first material is solid and comprises thermoplastic properties and the second material is solid and is penetrable by the first material when in a liquefied state. The device comprises a vibration device being configured to transmit vibrations to said insert to cause at least partial liquefaction thereof and being arranged to move, relative to said structure, along an insertion direction (ID) to insert said insert at least partly into said structure, a contact sensor being connected to the vibration device and being adapted to move together with the vibration device along the insertion direction (ID), the contact sensor having a sensor body being adapted to detect contact with said structure. A controller is further connected to the contact sensor and adapted for receiving a contact signal from the contact sensor indicating that the sensor body has come into contact with said structure.

A method and system of affixing a plaque to a solid surface is provided. The method includes the steps of providing at least one opening in a face of the solid surface and inserting a plaque support into the at least one opening. The plaque support includes a body defining a passageway therethrough and having a first end and a second end. The first end has a flange portion. Further, at least one outer tab member extends radially outward toward the first end and at least one inner tab member extends radially inward toward the second end. The outer tab member engages the solid surface upon insertion of the plaque support into the at least one opening. The method and system further include providing the plaque with at least one installation fastener. The at least one installation fastener is inserted into the passageway of the plaque support, such that the at least one inner tab member engages the at least one installation fastener.

A metal joint adapted to be fitted into a hole formed in a building component and fixed to the hole with an adhesive includes: a small diameter portion having an elongated shape and an outer diameter smaller than an inner diameter of the hole; and two large diameter portions fixed to the small diameter portion individually at two locations spaced apart from each other in a longitudinal direction of the small diameter portion, each large diameter portion having an outer diameter corresponding to the inner diameter of the hole. Furthermore, irregularities are formed on an outer peripheral surface of the small diameter portion in a section between the two large diameter portions.

Method and means of manufacturing ties, fasteners and rods (15) having a plurality of longitudinal threads by forcing a coil of roll-profiled feed-wire made of steel (11) through a twisting-die made of plastic (1). Also described is: a twisting-die made of plastic (1) that is suitable for twisting profiled feed-wire (11) made of steel; a method of forming a plastic twisting die (1) using an driven tap (31) in the form of a twisted rod (15); and a helically-shaped member (15) having lead measurements (X) along the length of the helical thread that vary less than pitch measurements (Y) along the lengths of the helical threads.
