An anchor channel is provided, including a channel element that has a plurality of identical fastening points and a plurality of identical anchor elements that are attached to the fastening points on the channel element. It is provided that an additional element is attached to at least one of the fastening points, said additional element differing from the identical anchor elements.

Anchor rail

The invention relates to an anchor rail arrangement with a concrete body which has two end faces which extend at an angle to one another and meet at an outer edge, and with two anchor rails which are embedded in the concrete body, wherein the two anchor rails each have a rail body with a longitudinal slot, wherein the longitudinal slot of the first rail body emerges on the first end face and the longitudinal slot of the second rail body emerges on the second end face on the concrete body, and wherein the two longitudinal slots extend in a common rail plane, wherein the first anchor rail has a plurality of first anchor bodies arranged on the first rail body, namely a first anchor body closest to the edge and at least one further first anchor body, and wherein the second anchor rail has a plurality of second anchor bodies arranged on the second rail body, namely a second anchor body closest to the edge and at least one further second anchor body. According to the invention, the first anchor body closest to the edge is a headless anchor bar and the second anchor body closest to the edge likewise is a headless anchor bar.

Anchor rail arrangement

The present invention relates to a cast-in channel having a channel body which forms a receiving space for receiving a connecting element used to fixedly attach a fastening element to the cast-in channel, the channel body further being provided with holes, the holes having connectors provided therein for fixedly attaching anchoring members to the channel body. The connectors are designed as rivets, whose fixing portions, which are inserted through the respective holes, are expanded so as to secure the rivets to the channel body, and which have an attachment for fixedly attaching the anchoring members to the channel body. The present invention also relates to a rivet nut for a cast-in channel.

Cast-in channel

A hollow profile () formed of a flat material () having a width (d) has at least one groove () provided on an outer side of at least one of the plurality of walls () of the profile () and having a bottom () spaced form the outer side by depth (t) and two opposite, substantially flat side walls () extending substantially perpendicular to the bottom (), with the groove depth (t) of the at least one groove () amounting to from 0.5 to 2 times of the material thickness (d) of the flat material ().

Hollow profile

A quick mounting nut () movable, at least partially, without being rotated, axially to a threaded bolt (), with a springing wire clip () being located in a nut housing () with a continuous coaxial opening (), with the wire clip () at least partially engaging in a bolt thread () and having two legs () which spring relative to one another, with the opening () having an inner cone () which narrows radially from an axial neutral position of the wire clip () and with the wire clip () being movable axially to a limited extent and contacting at least partially inside the inner cone () in its locking position.

Quick mounting nut

A connection element for a bolt and having a bolt-receiving member ( ) the bore of which has a cylindrical receiving region ( ) and a tapering, at least sectionally, in a direction opposite to an insertion direction (A) of the bolt ( ), region ( ) that adjoins the cylindrical receiving region ( ) at its side facing in the direction opposite the insertion direction (A), a guide region ( ) that adjoins the cylindrical receiving region ( ) at its insertion direction side and has an inner diameter (d ) which at most corresponds to an outer diameter of the bolt; and at least one locking member ( ) arranged in the bore ( ), formlockingly engaging, at least partially, in the outer thread ( ) of the bolt ( ), and formed as a radially expandable ring body.

Connection element for connecting a bolt-supported part with the supporting bolt

A quick mounting nut ( ) movable, at least partially, without being rotated, axially to a threaded bolt ( ), with a springing wire clip ( ) being located in a nut housing ( ) with a continuous coaxial opening ( ), with the wire clip ( ) at least partially engaging in a bolt thread ( ) and having two legs ( &prime;) which spring relative to one another, with the opening ( ) having an inner cone ( ) which narrows radially from an axial neutral position of the wire clip ( ) and with the wire clip ( ) being movable axially to a limited extent and contacting at least partially inside the inner cone ( ) in its locking position.

A connection element for a bolt including a member for receiving the bolt ( ) and including a bore ( ) having a tapering region ( ) adjoining a bore cylindrical receiving region ( ) and tapering in a direction opposite a bolt insertion in direction (A); and a locking member supported in the bore ( ) for forcelockingly engaging the bolt ( ) and formed as a radially expandable annular member having an inner diameter (w), which is, at least partially, smaller than an outer diameter (d ) of the bolt ( ), and an axial length corresponding to an axial length of the cylindrical receiving region ( ).

Connection element

A quick-made connection for a stud (,) having a shaped outer profile (,), the connection including a receiving member (,) having a bore (,) in which the stud (,) is received, and at least one locking member arranged in the bore of the receiving member and formlockingly engageable in the shaped outer profile (,) of the stud (,), with the bore (,) having at least one section (,) tapering toward an insertion opening of the bore, with the locking member (,) being formed as a radially elastically expandable ring member preloaded against the wall of the bore and having an inner diameter (w) which is smaller than a bore diameter (d) at its entrance opening.
