Definitions

  • the invention relates to a method for producing a truss with at least one strut arranged between two spars and connected to them, which is formed from a continuous metal band, at least one spar has a U-shaped cross section and the metal band only on the back of the a belt is attached as a strut and then connected to the other belt and a truss made by this method.
  • a generic truss is already known from AT-B-175 370.
  • a longitudinal reinforcement is provided for the bracing in order to shorten the buckling length.
  • the introduction of the longitudinal reinforcement increases the manufacturing costs of this truss.
  • this truss has the disadvantage that ceilings or ceiling trusses can only be stored on the actual trusses. This increases the height of the buildings to be constructed by the height of the truss girders required for structural reasons.
  • AT-B-279 127 another truss with a zigzag strut located between two spars is known. With this truss, there is.
  • Bracing from a flat band which consists of successive in its longitudinal direction sections corresponding to the length of the struts with opposite longitudinal profiles.
  • the flat strip can have an angular, undulating or channel-shaped cross section. Due to the flat band to be deformed for bracing, this truss girder requires a relatively high manufacturing effort.
  • DE-A-1 961 696 describes a developer and its manufacture, which consists of a base rail on which a zigzag-shaped web is fastened. A floor covering can be connected with the flat ends of the web. The floor covering should take over the static function of an upper chord. For this purpose, it is necessary that the floor covering is connected to each tip of the web, which makes the overall concept relatively complicated and requires a relatively large amount of installation work. With this developer, too, the installation of a ceiling results in a relatively large overall height.
  • the object of the invention is to demonstrate a method for the simple manufacture of a truss, by means of which the ceiling of a building can be integrated into the truss within its overall height.
  • the object is achieved in that, before the upper flange is attached to the strut, a sheet metal ceiling layer is placed on the strut, the profile shape of which corresponds to that of the strut, the strut optionally consisting of a strip-shaped section separated from the ceiling layer.
  • the truss 1 consists of a lower flange 2 and an upper flange 7 and a strut 6.
  • the lower flange 2 has a U-shaped cross section and is arranged so that the side webs 3, 4 are directed downward.
  • the strut 6 is fastened on the surface of the central web 5 of the lower flange 2 facing away from the side webs 3, 4.
  • the upper chord 7 is fastened on the surface sections 9 of the strut 6 facing away from the lower chord 2 and parallel to them.
  • the upper chord 7 has a generally rectangular cross section and can be designed, for example, as a sheet metal strip or the like.
  • the strut 6 preferably consists of a sheet metal strip 12 having flat surface sections, which is zigzag-shaped.
  • the lower flange 2 and upper flange 7 can be connected to the strut 6 by means of riveted or screwed connections. It is also possible to provide welded or adhesive connections.
  • the lower flange 2 is designed so that it can be plugged directly onto support columns of skeletal structures.
  • the lower flange 2 is preferably designed such that the side webs 3, 4 abut the support columns.
  • the connection to the support columns can be made in a manner known per se by means of screw bolts or rivet connections. If a further floor is to be formed above the truss and further supporting columns are to be arranged on the truss, one with a U-shaped cross section can be used as the upper chord.
  • This truss 1 shown in FIG. 1b is designed like the truss 1 except for the upper chord 8.
  • the upper flange 8 is, however, U-shaped in cross section and arranged in such a way that the side webs 16, 17 are directed upwards. Support columns, infill elements or the like can then be inserted between the side webs 16, 17.
  • the strut 6 is connected to the central web 15 of the upper flange 8 via the surface sections 9.
  • FIG 2 is a truss 1 in one pictorial view shown in an exploded view.
  • the lower flange 2 can be attached to differently designed support columns 11 of a skeleton construction 10.
  • the strut 6 designed as a sheet metal strip 12 is fastened to the lower flange 2.
  • the sheet metal strip 12 can be formed as a special folded sheet metal profile or can be a blank 14 from a ceiling layer 13, which is profiled like the strut 6 and is to be mounted on the truss 1. If such a ceiling layer 13 is to be supported on the truss 1, it is placed on the latter before the upper chord 7 is fastened with the strut 6.
  • the upper chord 7 is placed in alignment with the lower chord 2 on the ceiling layer 13 and this is connected to the strut 6 in a tensioning manner.
  • the top chord 8 shown schematically can also be used, so that the top layer 13 can also be inserted into a truss 1 a.
  • the overall height of each floor is reduced by the height of an otherwise required support layer.
  • the tread and visible surfaces on the ceiling layers 13 are created in the usual way by planks or the like to be attached in particular.
  • the channels formed by the profiling of the ceiling layer 13 can ud as supply channels for supply lines. Like. Be used.
