Definitions

  • the invention relates to a device for suspending C-shaped mounting rails according to the preamble of claim 1.
  • anchor hangers are used in the construction of substructures for suspended ceilings for hanging ceiling support rails used, so-called angle anchors, on the other hand, for connecting support rails which cross one another essentially at right angles.
  • the mounting rails are lightweight sheet metal profiles with a profile web lying at the bottom in the assembly position and extending from this at a distance from each other, upwardly directed profile legs, along the upper edges of which inwardly directed flanges are folded.
  • the anchor hangers are usually flat stamped parts cut out of sheet metal, which in one position of their anchor head transversely to the longitudinal extension of the C-shaped mounting rails engage with their lateral holding sections in the mounting rails in such a way that a positive connection between the lateral holding sections and the after inward flanges of the mounting rails.
  • the width of the anchor bar with the holding sections is approximately equal to the internal dimension between the profile legs of the mounting rails and the extension extending at right angles thereto is such that the holding sections engage behind the holding flanges of the mounting rails mentioned, while the side of the anchor head remote from the anchor bar is on the profile bar supports the mounting rail.
  • the anchor hangers When building a substructure, the anchor hangers are mounted at predetermined distances from one another on the support rails intended for the latter and then for example attached to suspension means, which are pre-assembled on the structural ceiling to be provided with such a substructure. Often, these are hanging wires that are correctly positioned on the ceiling of the building and are then inserted into clamping brackets attached to the anchor bars of the anchor hangers. As a result, a tensile connection between the clamping brackets and the suspension wires mentioned is achieved in a manner of no particular interest here.
  • the angled anchors are usually flat stamped parts cut from sheet metal with an anchor head with two lateral holding sections, which is installed in the mounting position in the same way as the anchor head of an anchor hanger from the open side in a mounting rail and with the lateral holding sections engages behind the inwardly folded edge flanges on the free longitudinal edges of the mounting rail legs.
  • Angle anchors are used, for example, to attach C-shaped ceiling profiles on the underside to support rails with a C or U-shaped cross-section which are spaced apart from one another in a plane and are in turn suspended from a structural ceiling, for example by means of the anchor hangers mentioned above.
  • Such angle anchors are also used in the construction of double-skin suspended ceilings, for example in suspended ceilings with a top structure and a substructure suspended from a structural ceiling Fire protection cover and an underside visible ceiling, the plates or panels of which are attached to a substructure suspended under the substructure carrying the fire protection cover, which in turn consists of C-shaped support rails attached to the substructure carrying the fire protection cover using angle anchors.
  • the center bar which extends from the anchor head on the open side of the mounting rails, is equipped with means for fastening to an unfinished ceiling, such as clamp brackets for receiving a preassembled hanging wire, the ends of the anchor bars are removed from the anchor head for the angle anchors formed as a bendable holding tabs.
  • the angle anchors are mounted in the same way as the anchor hangers on support rails to be attached under an already suspended substructure in such a way that the anchor bars extend in the transverse position to the longitudinal extension of the support rails on their open side.
  • the support rails equipped with pre-assembled angle anchors are then placed on the underside of already installed U- or C-shaped support rails, so that the upstanding anchor webs extend laterally along a raised profile web of a support rail along the already assembled substructure.
  • the form-fitting fixed connection of a lower mounting rail with an upper mounting rail extending at right angles to this then takes place in such a way that the upstanding ends of the Anchor webs are bent around the upper edge of the upstanding profile webs of an upper support profile, whereby the lower support rails are more or less braced with the upper support rails and fixed to the latter without rattling.
  • Both the mounting rails as well as the anchor hangers and angle anchors are mass parts in which inevitable dimensional deviations can lead to pre-assembled anchor hangers not being held securely in the mounting rails. Accordingly, the attachment of the mounting rails equipped with preassembled anchor hangers to the suspension means preassembled on a building ceiling is often difficult and time-consuming. The same applies analogously when connecting support rails that cross each other, because the preassembled angle anchors easily tip out of their mounting position before the upper ends of the anchor webs designed as holding tabs can be bent into a holding position that overlaps the upstanding legs of the respective upper mounting rail.
  • Typical devices for suspending C-shaped support rails of the type described above are described in DE-A-3 409 992 and 2 652 481 and in FR-A-2 546 939 and 2 467 927.
  • the holding sections of the anchor hanger have tabs bent at right angles to the level of the anchor head, which in the installed position engage behind the edge flanges of the support rails to be suspended, which ensures improved load distribution, but a type of protection against undesired tipping of the preassembled Anchor hanger is not provided.
  • Both the support tabs and the spring tongues are formed on one side of the anchor head.
  • the support brackets stand on the profile web of a mounting rail and, together with the spring tongues acting on the mounting rail edge flanges at a distance from the points of attachment of the holding sections, provide a securing of the position of preassembled anchor hangers.
  • the underlying object of the invention is to provide an easy-to-install device for hanging C-shaped support rails, which is received and held securely in position in the respective support rail in the preassembled state and also accepts larger loads without the risk of deformation in the region of the lateral holding sections and the edge flanges of the mounting rails that are gripped by these in the assembly position.
  • the lateral holding sections are shaped approximately semicircularly out of the plane of the anchor head middle part and are provided with curved holding surfaces engaging behind the support rail edge flanges in the assembly position, towards the side facing the anchor bar.
  • the holding sections of the device according to the invention each have two spaced engagement areas and engage behind the mounting rail edge flanges with their holding surfaces essentially over their entire length. They are therefore safely held in the preassembled state with good load distribution and the risk of tipping over an axis running transversely to the longitudinal direction of the mounting rail is practically excluded, because in view of the semicircular arch-shaped holding sections formed out of the plane of the anchor head center part and the curved sections towards the side facing the anchor bar The latter hold the support rail edge flanges in a form-fitting manner over a large length.
  • An advantageous development of the invention provides that the extent of the holding sections in the direction of the anchor web is greater than the height of the profile legs of the support rails to be suspended and that the holding sections are provided with lateral notches, the boundaries of which are removed from the anchor web and form the curved holding surfaces which form the support rails - Reach behind the flanges in the assembly position. If the extent of the notches in the lateral holding sections is dimensioned in accordance with the extent of the mounting rail edge flanges in the direction of the height of the profile legs, the edge flanges which protrude into the notches in the mounting position and are gripped by the lower boundaries of the notches provide further protection against undesired tipping in the pre-assembled condition.
  • an embodiment of the device according to the invention serves such that the anchor head and / or the holding sections on the side remote from the anchor web are provided with feet that stand up to a certain extent in the mounting position on the mounting rail profile web.
  • a further embodiment according to the invention provides that the end section of the anchor web, which is removed from the anchor head, is designed as a bendable holding tab and at a distance corresponding to the height of the mounting rail profile leg from the lateral holding sections with a transverse to the anchor web extension on the side of Holding sections molded spring tongue is provided, which can be easily clipped onto the upper edge of the support rail belonging to the already suspended substructure when attaching a support rail equipped with preassembled angle anchors to a support rail of a previously suspended substructure, before the bendable retaining tab around the upper edge of the above-mentioned upper Carrier rail is bent around.
  • two anchor hangers 18 are arranged along the support rail at a distance from one another, which engage in a form-fitting manner between the upright profile legs 12 of the support rail 10 in the manner to be described below and in turn by means of clamping springs 16 which cooperate with hanging wires 15 fastened to a structural ceiling (not shown) are suspended from the suspension wires mentioned.
  • the anchor hanger 18 is a molded sheet metal part with an anchor head 20 formed symmetrically to a central axis 19, which has two lateral holding sections 21, and with an anchor web 22 which extends on one side from the anchor head and is integrally formed therewith.
  • the lateral holding sections 21 of the anchor head 20 are also formed integrally therewith and are bent semicircularly to one side in each case from the plane spanned by the anchor web 22 and the central part of the anchor head.
  • both holding sections 21 there are, as shown in particular in FIG Development shows, in the vicinity of their ends pointing toward the anchor web 22 notches 24, the extent of which in the direction of the anchor web 22 is dimensioned such that they are able to encompass the inward-facing edge flanges 14 at the ends of the profile leg 12 of the mounting rails remote from the profile web 11.
  • the boundaries 25 of the notches 24 in the holding sections 21 are arcuate and in the middle of the anchor head 20 and at the ends of the circular arc-shaped holding sections 21 feet 26, 27 are formed on the underside.
  • the outer dimension of the circular arc-shaped holding sections 21 is slightly smaller than the inner dimension between the profile legs 12 of the support rails 10 to be suspended by means of the anchor hanger and the extent between the feet 26, 27 of the anchor head 20 and the holding sections 21 on the underside and the arcuate boundaries 25 of the notches removed from the anchor web 24 is approximately the same as the distance between the profile web 11 and the edge flanges 14 bent inwards from the profile legs 12.
  • reinforcing beads and perforations for attaching, for example, the clamping spring 16 - or other suitable attachment means - are not provided here in the anchor web.
  • FIG. 3 and 4 show in connection with a carrier rail 10 indicated by dash-dotted lines the mounting position of the anchor hanger 18, in which the plane spanned by the anchor web 22 and by the central part of the anchor head 20 extends transversely to the longitudinal direction of the carrier rail.
  • the bottom feet 26, 27 of the anchor head 20 and The holding sections 21 formed thereon in a semicircular arc stand on the profile web 11 of the mounting rail 10, while the edge flanges 14 bent inwards from the profile legs 12 engage in the lateral notches 24 of the holding sections 21 and in turn are undercut by the circular-shaped undersides 25 of the notches.
  • the anchor head with the holding sections 21 is thus clamped between the profile web 11 and the edge flanges 14 of the mounting rail 10 and in view of the feet 26, 27 spaced apart in the longitudinal direction of the mounting rail on the underside of the anchor head and at the ends of the circular-shaped holding sections, the anchor hangers are on the Profile web of the mounting rail. This largely eliminates the risk of the preassembled anchor hanger tipping over.
  • the correct mounting of the anchor hangers in the preassembled state is also reinforced by the fact that the curved lower boundaries 25 of the notches 24 in the holding sections 21 engage behind the inwardly bent support rail edge flanges 14 over a predetermined extent in the longitudinal direction of the support rail.
  • the latter also leads to a load distribution over a predetermined length section of the edge flanges of the mounting rail, so that deformations of the edge flanges are practically excluded even when larger loads occur. Deformations on the holding sections themselves, given their semicircular shape and shape the engagement of the mounting rail edge flanges in the notches mentioned do not occur anyway.
  • the assembly of the anchor hanger 18 according to the invention on the support rails 10 is achieved in a simple manner by the anchor head 20 of the anchor hanger between the upwardly directed profile legs 12 of the support rails and the edge flanges 14 directed inwards from the free longitudinal edges of the profile legs in an oblique position to the longitudinal extension of the support rails introduced and then rotated about the central axis 19 such that the plane spanned by the anchor web 22 and by the central part of the anchor head 20 extends at right angles to the longitudinal direction of the mounting rails.
  • the edge flanges 14 of the mounting rail come into the notches 24 of the lateral holding sections 21 and are engaged behind by the arched lower boundaries 25 of these notches.
  • the feet 26, 27 formed on the underside of the anchor head and the holding sections then stand on the profile web 11 of the mounting rail and the anchor head is clamped between the said profile web and the mounting rail edge flanges 14.
  • a clamping spring 16 is fastened to the anchor web 22 by means of rivets 30, which has two spring legs 31 which extend divergently towards one another from the anchor web.
  • transverse slots 32 are open on one side and are aligned with one another in the clamping spring legs 31 and extend transversely to their longitudinal extension and extend into the spring legs from the same sides.
  • illustrated angled anchor 18 ' is a sheet metal part with a symmetrical to a center line 19' formed anchor head 20 ', which has two lateral holding portions 21', and with one on one side of the anchor head extending anchor bar 22 '.
  • the holding sections 21 'extending from the level of the central part of the anchor head in a semicircular arc are not provided with lateral notches, but rather to the anchor web 22'.
  • indicative upper edges 25 ' are formed in the same way as the limits 25 of the notches 24 of the notches 24 in the anchor hanger 18 are arch-shaped and, when used as intended, engage under the inwardly bent support rail edge flanges 14.
  • the distance from the anchor web 22' Side feet 27 ' which are supported when used as intended on the mounting rail profile web 11, so that the anchor head is then clamped between the profile web and the inwardly bent edge flanges.
  • the anchor hanger 18 is at the angled anchor 18 'from the anchor head 20' distant end of the anchor web 22 'formed as a bendable mounting bracket 35 and spaced from the anchor head with one on the same side as the semicircular holding sections 21' issued Tongue 36 equipped, which is arranged approximately at a distance twice the height of the profile legs 12 of the mounting rails from the underside of the anchor head.
  • the free end of the anchor web 22, which is designed as a bendable retaining tab is bent by approximately 45 ° with respect to the plane spanned by the remaining anchor web.
  • the angle anchor 18 ' is used for attaching C-shaped mounting rails 10' to the mounting rails 10 of an already suspended substructure, which can be constructed from the same mounting rails.
