Definitions

  • the invention relates to a profile system with at least one rectangular cross-section hollow profile, which consists of at least one multi-folded and connected to the end edges of metal sheet and on the outer surfaces at least two adjacent undercut longitudinal grooves, whose one bottom of the groove with an undercut area connecting sheet sections abut each other, the Grooved bottoms define a hollow channel extending approximately around the longitudinal central axis, which serves to receive supporting or connecting elements and the sheet metal sections adjoining one another are firmly connected to one another.
  • Such a profile system is for example off DE-B-1484277 known.
  • a profile system which is a rectangular cross-section component consisting of at least one multi-folded and connected to the end edges metal sheet. Therefore, on the one hand, this document discloses, on the one hand, that the component can be made of metal and, on the other hand, that it can be produced by the rolling process. For this purpose, column 3, lines 46-57 must be observed.
  • this profile system which has on the outer surfaces at least two adjacent undercut longitudinal grooves, see in particular Fig.6, having a groove bottom with abut a sheet metal section connecting sheet metal sections. These groove bottoms define a hollow channel extending approximately around the longitudinal central axis, which serves to receive supporting or connecting elements, such as bolts 29, for example. Furthermore, the abutting sheet sections forming a web are firmly connected to each other.
  • the invention has for its object to provide a profile system of the type mentioned, in which a technically simple means widening of the web forming Blechabschitte is prevented.
  • the hollow profile has three longitudinal grooves.
  • the hollow profile has four longitudinal grooves and all groove bottoms define the hollow channel. This makes it possible to form the hollow channel exclusively through the Nutenböden, so that no additional material for a hollow channel must be introduced.
  • each groove bottom is concave and the hollow channel is formed approximately circular in cross section.
  • each groove bottom has a thread embossed or has a complete internal thread for receiving a screw. This eliminates the need to introduce an internal thread in an additional operation for receiving a screw in the longitudinal direction of the hollow profile in the hollow channel.
  • the hollow profile may consist of first and second half-shells, the ends of which have to be directed towards one another in each case being joined together to form a groove bottom.
  • the profile system has an increased force absorption, it is advantageous if two hollow profiles are welded together to form a rectangular cross section and the fourth and fifth weld seams extend in the joining region near the respective outer surfaces in the longitudinal direction.
  • At least one further hollow profile with one of the two hollow profiles is welded in alignment therewith and extend sixth and seventh welds in the joining region near the respective outer surfaces in the longitudinal direction.
  • the number of hollow sections can also be four or even more.
  • a particularly safe and accurate arrangement of the welds can be achieved if all welds have been created by means of a laser beam.
  • the hollow profile is made of stainless steel.
  • Each of the three profile systems 10, 10 ', 10 "contains at least one hollow profile 12 which is rectangular in cross-section.
  • Each hollow profile 12 is produced from at least one multi-folded sheet metal sheet connected to one another at the end edges. The folding or bending has been carried out such that the hollow section 12 has an undercut longitudinal groove 14 on each of the outer surface.
  • the respective lateral walls are formed by sheet metal sections 20 which connect a groove bottom 16 with an undercut region 18.
  • the longitudinal grooves 14 are arranged in all embodiments so that touch the sheet metal sections 20.
  • the inner surfaces of the Nutenböden 16 define a running approximately about the longitudinal center axis 22 hollow channel 24. This hollow channel 24 serves to receive support or connecting elements.
  • the abutting sheet metal sections 20 are firmly connected to one another and thereby form a web 26.
  • the sheet metal sections at any area 28 of the web 26 are welded together.
  • this region 28 is located in the vicinity of the groove bottoms 16 facing the end of the web 26.
  • the region 28 is for reasons of clarity, only in Fig. 4 indicated.
  • the cross-sectional shape of the hollow channel 24 can be chosen approximately arbitrarily. But if each groove bottom 16 of the embodiments shown is concave and each hollow channel 24 is thus circular in cross-section, it is possible to introduce into this hollow channel 24, a so-called self-tapping screw as a connecting means.
  • the free ends of the metal sheet for forming the hollow profile 12 are arranged so that they can be connected together along a groove bottom. This is according to Fig.1 the hollow profile 12 is provided with a second weld 36.
  • hollow section 12 of the first and second half shells 32 , .-. 34 to assemble, wherein the ends facing each other are welded together at a groove bottom 16.
  • the half-shells 32 and 34 are identical. But it is also possible to choose other partial forms. Unlike the in Fig. 1 shown hollow section 12 therefore has the in Fig. 2 shown hollow section 12 an additional third weld 38, which is disposed opposite to the second weld 36.
  • FIG. 1 Another difference between those in Fig.1 and 2 shown hollow sections 12 is that the sheet metal sections at the openings of the longitudinal grooves 14 according to Fig. 1 are bent to each other so that a cavity 48 is present. In contrast, in the hollow section 12 according to Fig. 2 the curvature has been set so tight that there is a composite area 50.
  • the hollow profile 12 according to Fig. 1 can also be made so that it forms a composite region 50 and that the hollow profile 12 according to Fig. 2 can be formed so that it forms the cavity 48.
  • a second embodiment of a profile system 10 ' is shown. It consists in this case of two interconnected hollow sections 12 according to Fig. 1 , Of course, it is also possible here, such a compound of in Fig. 2 shown hollow profiles or to choose a mixture.
  • a third embodiment of a profile system 10 '' is shown, which in this case consists of an assembly of three hollow sections 12 according to Fig. 2 consists. Again, it is possible that in Fig. 1 shown profile in this manner, or even a mixture of slightly different profiles.
  • the two hollow profiles 12 are joined in alignment on respective opposite longitudinal sides so that they form a quasi-rectangular cross-section.
  • the connection takes place here with fourth and fifth welds 40 and 42, which are arranged in the joint areas near the respective outer surface and extend in the longitudinal direction.
  • a third hollow section 12 is connected in alignment with a hollow section 12, in this case arise the sixth and seventh welds (44, 46).
  • hollow profiles 12 in the embodiments shown are all made of stainless steel.
  • hollow sections 12 shown have been produced by means of a highly modern rolling process in a rolling train.
