Abstract: A nut for accommodation in an open channel section (1) is comprised by a main body (6) provided with a threaded hole (7) and a gripping means (8) connected to the main body. The gripping means comprises a clamping device (9) for co-operation with the limiting edges (3, 4) of a longitudinal opening (2) in the channel section. During insertion of the nut in the channel section the gripping means is subjected to a torque about two generally orthogonal axes, and upon completed insertion the nut is held in the correct position by means of a form and/or friction locking co-operation between the limiting edges (3, 4) of the opening (2) and indentations (12, 13) in the legs of a U-shaped loop (9) constituting the clamping device.

Abstract: An anchorage for attachment of ties to walls, floors and ceilings of various kinds, e.g. for attachment of a facing to a concrete wall, consists of a tubular aluminum section (1) having a longitudinal slot for introduction of one end (6) of the tie (5). The slot of the section is provided with edge portions (4) which are curved outwardly so that their end portions extend about tangentially with respect to the cross section of the section. At the opposite side of the slot the section is provided with attachment flanges (2).The tie (5) consists of a cold-drawn stainless steel wire which at one end is looped to an eye (6), the free end (14) of which being bent transversally and extending some distance outwardly in order to prevent twisting of the tie in the anchorage section. The other end is provided with a transverse portion for securing in mortar or for cooperation with a safeguarding plate (12).
