Abstract: A fastening system comprises in combination a fastening unit (20) and a steel installation channel (1) having a bottom wall (2) and opposite the bottom wall flanges (5) which extend towards each other and which delimit between them a longitudinal slot (6) extending over the length of the installation channel. The bottom wall (2) comprises two side strips (2A) and a central strip (2B) located between the side strips, which central strip is arranged recessed with regard to the plane defined by the side strips, and has oblong openings (7). The fastening unit comprises an oblong anchoring element and tensioning means. In use the anchoring body with its longitudinal axis can be inserted between the longitudinal edges of the oblong opening and between the flanges delimiting the longitudinal slot.

Abstract: A one-piece conduit clip made of spring steel sheet material includes an elongate anchor plate for coupling to a channel member having a longitudinal slot defined between two flanges. The clip includes two opposing arms interconnected by the anchor plate. The arms include a holding portion remote from the anchor plate to hold the conduit. A closure portion extends from an end of the holding portion. Between a lower end of the holding portion and each axial end part of the anchor plate an accommodation space is defined for a flange of the channel member when the anchor plate extends at an angle relative to the longitudinal slot. The anchor plate has resilient lugs at its axial end parts adapted to engage the flanges so as to pull the lower end of the holding portion into engagement with an upper side of the flanges.

Abstract: An attachment assembly includes an elongate channel element and a male fastening element including a shank to fasten the channel element to another structural element. The elongate channel element has a substantially flat bottom, sidewalls extending from the bottom substantially at right angles and an upper side opposite the bottom. The upper side of the channel element includes flanges which extend from the respective sidewalls towards each other and delimit between them a longitudinal slot extending over the length of the channel element. The bottom has an aperture formed in it for passing through the shank of the male fastening element. The male fastening element has a head that has a circular groove in the side where the shank is located. The groove in the head is engageable with a collar surrounding the aperture so as to mutually lock the head and the bottom in position at the aperture.

Abstract: A pipe clamp includes two clamp parts for fastening a pipe to a channel type profile element having a longitudinal slot. Each clamp part has a curved pipe clamping portion, where in a mounted state the pipe clamping portions of the respective clamp parts are positioned opposite each other to accommodate a pipe section. Each clamp part has an anchoring portion formed at one end of each clamp part to anchor the pipe clamp to the profile element. The anchoring portion is essentially formed as a leg with a hammerhead, which is insertable in the longitudinal slot of the profile element and rotatable to engage the slot edges. A flange is formed at another end of each clamp part. The pipe clamp furthermore includes a tightening member associated with the clamp flanges for tightening them together.

Abstract: A vibration-isolating insert for a pipe clip is adapted to bear against an inner circumference of a substantially annular pipe clip body and ultimately, in use, to be positioned between the outer circumference of a pipe and the pipe clip body. The vibration-isolating insert includes an elongate strip of vibration-isolating material which has a pipe facing side and a pipe clip facing side. The strip of vibration-isolating material has adjacent either lateral edge thereof a series of discrete exposed hooks of plastics material which is more rigid than the vibration-isolating material. The hooks protrude relative to the pipe clip facing side of the strip of vibration-isolating material.

Abstract: A partition is penetrated by a duct. The partition has a passage through which the duct passes. A fire stop sleeve is positioned in the passage and arranged around the duct. The fire stop sleeve includes a casing having a tubular form and one or more elements of intumescent material arranged on a side of the casing facing the duct. The casing is provided with at least one movable retaining member which lies within an outer contour of the casing. The movable retaining member is actuable by intumescent material such that, in the occasion that swelling of the intumescent material occurs, the retaining member is moved radially outward towards engagement with a passage wall in the partition so as to retain the sleeve in the passage.

Abstract: A connector, for connecting two profiled-section elements of the channel type having a bottom and an upper side formed by flanges defining between them a longitudinal slot, includes an elongate connector body designed to be inserted partially into each of the profiled-section elements to be connected from the respective longitudinal ends thereof, where the connector body is at least provided with two bores. The connector includes at least two screws, the screws having a shank having a tip on one end and a head on another end, where the shanks of the respective screws extend through the respective bores. The connector body includes a connector plate with upstanding edge portions on either lateral side thereof, the upstanding edge portions having a top edge remote from the connector plate 3, the top edges, in use, facing the flanges of the profiled-section element.

Abstract: A pipe clip for fastening a pipe to a support structure includes an annular pipe clip body for surrounding the pipe to be fastened. The pipe clip body has a first and a second flange which in use are pulled towards each other by a male fastening element having a head and a shank. The second flange is associated with a female fastener via which the male fastening element is connected to the second flange. The first flange has a longitudinal slot which has an open end opposing the closed end, the open end opening up in an edge of the first flange for introducing the shank of the male fastening element into the slot. The first flange has an upstanding collar portion around the closed end of the cutout.

Abstract: A support channel for a pipe comprises a plurality of basic channel bodies having an elongate form with an arched channel wall seen in cross section. The support channel furthermore comprises at least one interconnecting channel body that is arranged between the end portions of two of the basic channel bodies. The end portions of the basic channel portions are received in the interconnecting channel body. Fixing means are provided to fix the interconnecting channel body and the basic channel bodies together.
