Definitions

  • the invention relates to a profile strip designed as a lightweight construction profile, in particular a ceiling support profile, with two legs which are spaced apart from one another in the longitudinal direction of the profile and are connected to one another by a web, at the free ends of which are distant from the web, each have an inward, approximately parallel position to the web and in Profile longitudinally extending flange is formed.
  • ceiling support profiles which generally have C-shaped cross sections, are mostly rolled profiles made of thin sheet metal, the one of which is connected by a web connected legs are provided at the ends remote from the web with molded, inwardly directed flanges and thereby stiffened.
  • the object on which the invention is based is therefore to remedy the shortcomings observed in such profiled strips and to provide a profiled strip which is improved in terms of its dimensional stability, load-bearing capacity and rigidity compared to the prior art.
  • a profile strip designed as a lightweight profile, in particular a ceiling support profile, of the type specified at the outset in that the legs are each provided with at least one stiffening longitudinal embossing which extends in the longitudinal direction of the profile and, in addition to these longitudinal impressions, with essentially transverse to the longitudinal profile equidistantly arranged cross beads are equipped.
  • Profile strips in particular plaster profiles, with reinforcing beads running in the longitudinal direction of the profile strips have already become known from thin-walled sheet metal strips, but these strips are not lightweight profiles that can be used, for example, as ceiling support profiles, column profiles or for other purposes in drywall construction. Rather, such lightweight construction profiles must have a load-bearing capacity, dimensional stability and rigidity which correspond to the respective application requirements.
  • the desired dimensional stability, load-bearing capacity and rigidity are achieved by shaping according to the invention, because the transverse beads give the legs connected to one another via the web of such a profiled strip in addition to the longitudinal embossments and the stiffening by the Flanges formed on the free leg ends have increased rigidity, which, even when obliquely acting forces occur, prevents deformation of the legs and thus damage to the profile strips with a high degree of safety. It has proven to be expedient if the cross beads run at right angles to the longitudinal profile.
  • transverse beads extend into the stiffening longitudinal impressions of the legs, that is to say they are also formed in the material of the legs in the region of these longitudinal impressions.
  • Cross beads extend beyond the longitudinal edges connecting the legs to the web and extend at least over part of the width of the web, that is to say they are guided around said longitudinal edges.
  • the transverse beads either extend around the longitudinal edges connecting the legs to the web or extend from these longitudinal edges into the longitudinal embossments of the legs
  • a fish skin profiling allows on the one hand the attachment and screwing in of screws with self-tapping threads, which considerably simplifies assembly, for example when attaching building boards to such profiles, but on the other hand such a fish skin profile also leads to a very desirable increase the stiffness.
  • the transverse beads can also extend through the stiffening longitudinal embossments and reach approximately to the flanges which are formed on the free ends of the legs which are distant from the web.
  • transverse beads are each shaped outwards from the legs and / or from the web of the profile strip and thus protrude beyond the planes spanned by the legs or the web on the outside of the profile, which, in the case of the attachment of building boards, enables them to be held without extensive contact with the legs or the web. Cold bridges and the transmission of structure-borne noise are naturally significantly reduced.
  • the arrangement can also be such that a longitudinal impression extending in the longitudinal direction of the profile extends in the central part of the web at a distance from the legs and that the transverse beads extend as far as this longitudinal impression.
  • the longitudinal embossing in the central part of the web can be provided with a fish skin profile which facilitates the screwing in of screws with self-tapping threads and which also contributes to an improvement in the dimensional stability.
  • the ceiling support profile is a C-profile, the legs 11, 12 of which run parallel to one another in the longitudinal direction of the profile are connected to one another via a web 13 and are directed towards one another at their ends remote from the web and in parallel to the web flanges 14, 15 are molded.
  • the two legs 11, 12 are provided in the area between the flanges 14, 15 and the web 13 with stiffening longitudinal impressions 16, 17.
  • a similar longitudinal impression 18 extends in the central region of the web 13 in the longitudinal direction of the profile.
  • This longitudinal embossing 18 in the middle part of the web 13 and the strip-shaped sections 19, 20 of the legs extending between the longitudinal embossings 16, 17 and the flanges 14, 15 are provided on the outside with fish skin profiles 21, 22 which are used to attach and screw in screws self-tapping threads easier.
  • the legs 11, 12 are above also equipped with equidistantly spaced transverse beads 24 which extend the strip-shaped sections 19, 20 of the legs through the longitudinal impressions 16, 17 and over the longitudinal edges 25, 26 in the region of the web 13 and in each case up to one of each of the legs Subsequent edge strips 27, 28 of the web reach into it.
  • transverse beads 20 are formed by the web 13 before the longitudinal embossments 16, 17 and the legs 11, 12 are formed. They extend through the longitudinal indentations 16, 17 in the legs and up to the longitudinal indentation 18 in the central part of the web 13.
  • FIG. 2 shows the development of the leg 11, indicated at 30 in FIG. 1, with the edge strips 27 of the web 13 adjoining the longitudinal edge 25, the oblique transitions between the material remaining in the plane of the leg through the auxiliary line 31, 32 and 33 , 34 and the longitudinal edge 25 are indicated by the auxiliary line 35.
  • the transverse beads 20 are also formed in the leg material in the region of the longitudinal embossments 16, 17 and also extend beyond the longitudinal edges 25, 26 between the legs 11, 12 and the web 13.
  • the fish skin profile 21 in the strip-shaped section 19 between the longitudinal embossing 16 and the flange 14 formed on the leg 11 is also shown in FIG. 2.
  • the transverse beads 24 are molded out of the leg material toward the inside of the profile.
  • the beads are formed on the outside of the legs 11, 12, that is to say they rise above the plane spanned by the leg material that has not been deformed, so that building boards attached to the legs in one by the Dimension of these elevations certain distance from the legs are kept, which has proven to be advantageous in terms of the desirable avoidance of cold bridges, but also in terms of structure-borne noise.
  • the transverse beads 24 ' extend beyond the longitudinal embossing 16' in the leg 11 'into the strip-shaped section 19 which extends on the side of the longitudinal embossing 16' remote from the web.
  • the longitudinal embossments 24 'therefore extend approximately to the flange formed on the end of the leg 11' remote from the web and are formed continuously in the region of the longitudinal embossment 16 '.
  • the longitudinal embossments introduced into the thighs and the longitudinal embossing in the central part of the web ensure that the transverse beads 20, 20 'have a shape stability which satisfies all the stresses that occur when used as intended and thus contribute to improving the rigidity and load-bearing capacity of such profiles'. If the transverse beads 20, 20 'are shaped outward from the leg material, they enable a spacing on the profiles of the building boards attached, which leads to a reduction in thermal bridges and structure-borne noise, but also results in improved fire protection.
  • the fitting of partial areas of the web and / or the legs with fish skin profiles enables an easier attachment of building boards by means of screws with self-tapping threads, which can be easily inserted in the area of the fish skin profiles and screwed into the profile material.
