Definitions

  • the invention relates to a covering platform for scaffolding, in particular scaffolding or the like, the covering platform being composed of at least two one-piece hollow profile bars which are detachably connected to one another on their longitudinal sides.
  • a covering platform of this type for scaffolding or the like is already known from DE Offenlegungsschrift 43 23 381 A1.
  • the hollow profile bars are cut out there along their entire length and shaped in such a way that they can be nested into one another by means of these recesses and a single profile is sufficient to be able to put together a complete decking platform together with suitable head pieces. Corrugations are provided which serve to ensure the rigidity and the connection of adjacent hollow profile bars.
  • the invention has therefore set itself the task of making a covering platform of the type described in more detail with simple means reliable and designed so that additional connecting elements between the hollow profile bars can be dispensed with and the covering platform can nevertheless be assembled in a dimensionally stable manner; a stacking aid for the covering platforms is also desirable.
  • the number of parallel hollow profile bars should be arbitrary, so that an advantageous width of these hollow profile bars does not have to be made dependent on the width of the covering platform.
  • the object is achieved in that the hollow profile bars are designed as closed extruded profiles, their abutting side faces parallel to the long sides of the support frame on one side of the respective hollow profile bar a continuous groove parallel to the side face and on the other side one complementary to the groove have shaped spring bung, whereby two adjacent hollow profile rods can be tied together by the groove of one and the spring bung of the other hollow profile bar placed therein, that the longitudinal sides of the support frame are also each formed by a similar, retractable hollow profile bar, but at one, the outer boundary of the support frame forming side is only provided with a preferably smooth side surface and is only equipped on the other side surface facing an adjacent hollow profile rod with a groove or a spring bung and that the transverse sides of the support frame each consist of a support profile on which the covering rests and that serves to secure the platform to the rest of the scaffolding.
  • a covering platform according to the invention can be assembled from individual hollow profile bars without specialist knowledge and can be fixed so firmly through the tongue and groove connection that a stable, walkable surface can be put together from very light extruded parts.
  • the parts do not have to be screwed or riveted and can be joined together in any number; In this way, a narrow division ensures a high load-bearing capacity of the covering platform even in the case of lightweight profiles due to the large number of vertical webs of the individual hollow profile bars that determine the section modulus.
  • a practically backlash-free connection of adjacent hollow profile bars is achieved, for example, by integrally molding a parallel, vertical web strip on the spring bung, which can be inserted into a parallel secondary groove, which is recessed into the lower side wall of the groove.
  • the design improves both the bending stiffness in the longitudinal direction and the dimensional stability in the transverse direction of the covering platform.
  • the hollow profile bars can essentially be formed with approximately the same wall thickness on all sides, that is to say including the areas of the tongue and groove bung. Such training is technologically favorable because thermal stresses that can occur with larger wall thickness jumps are avoided as far as possible during their manufacture.
  • the bordering hollow profile bars that form the long sides of the support frame are each provided with at least one bead on their top surface that serves as a tread surface and the flat surface opposite this surface, which is adjacent and parallel to the smooth side surface, in particular if the bead in the top surface is raised and that is recessed in the bottom surface, because in this way - in addition to the improved dimensional stability - the prerequisite is created for the beads to be dimensioned such that they come into contact with one another when decking platforms are placed one above the other and as Stacking aid to prevent mutual shifting of the covering platforms.
  • the covering platform is completed in an expedient manner if the supporting profile is designed as a U or L profile and the hollow profile bars rest on the lower horizontal belt adjoining the vertical web of the U or L profile, the hollow profile bars at least with their end regions can be partially attached to the support profile. It may already be sufficient to attach the bordering hollow profiles to the support profiles and only to hang up the others, especially when using U-profiles.
  • the covering platform according to the invention makes it possible to design the hollow profile bars forming the long sides of the covering platform in the same way or in mirror image; in the latter case, it is advantageous if a hollow profile rod on both sides is provided with a groove or a spring bung.
  • covering platforms of very different widths can be put together from the same basic structural elements; In this way, production and warehousing can be limited to a few different components and can be simplified accordingly.
  • a hollow profile rod 1 corresponding to FIG. 1 is produced by the extrusion process and has an approximately rectangular cross section.
  • a groove 11 is recessed into a first side surface 1 a, so that one bar 12 and 13, respectively, extending in a continuous manner remains above and below.
  • the lower bar 13 is solid, but, starting from the groove 1a, a secondary groove 13a is recessed, separated from the side surface 1a by a web 13b.
  • a second side surface 1b is - complementary to the groove 11 - provided with a raised spring bung 14, so that one each continuously along the top and bottom extending remaining space 15 or 16 remains.
  • there is a web strip 14a the cross section of which is complementary to that of the secondary groove 13a.
  • a top surface 1c and a bottom surface 1d between the side surfaces complete the cross section of the hollow profile rod 1.
  • the top surface 1c is structured to be non-slip
  • any number of hollow profiles 1 can be provided side by side, the groove 11 and the spring bung 14 is pushed into one another, the secondary groove 13a receives the web bar 14a and the upper remaining spaces 15 each filled with an upper bar 12 are. In this way, the hollow profile bars 1 are securely interlocked.
  • FIG. 2 Another hollow profile rod 1 ', which differs only slightly from that of FIG. 1, is shown in cross section in FIG. 2; it is used for mutual connection with a spring bung 14 and is therefore equipped on both side surfaces 1a 'with a groove 11', the grooves 11 'being axially symmetrical, but otherwise not different from the groove 11 in FIG. 1.
  • a strip 13 ' adjoins the cover surface 1c' in an axially symmetrical manner; Residual spaces 15, 16 are not available here. 4 and 5 make it clear that in a covering platform according to the invention at most one hollow profile rod 1 'is required, either (Fig. 4) between two bordering hollow profile rods 1' 'or (Fig. 5) between an "inner" hollow profile rod 1 and one of the bordering hollow profile bars 1 ''.
  • the hollow profile bars 1 ′′ bordering the covering platform according to the invention in the longitudinal direction are superimposed - Shown in Fig. 3. They differ from the hollow profile bars 1 and 1 'only in that no spring bung 14 is provided on them and the associated side surface 1b''rather forms a smooth wall surface. Both side surfaces 1b '' are consequently components of the covering platform, which is otherwise formed on its transverse sides by U-shaped or L-shaped supporting profiles on which all hollow profile bars are mounted, the simplest if they are on the (lower) belt of the respective Support profile rest and - at least the bordering hollow profile bars 1 '' - are positively or materially connected to the respective support profile.
  • the details are relatively arbitrary, have no direct connection with the invention and are omitted from the drawing.
  • the vertical smooth side surfaces 1b '' are accompanied in the top surface 1c '' and the bottom surface 1d '' by respectively adjacent beads 17 and 18, the beads 17 of the top surface 1c '' being raised and the beads 18 in the bottom surfaces 1d ''areengrossed; they are equidistant from the next side surface 1b '' and profiled so that they come into contact with one another in the case of stacked hollow profile bars 1 '' and accordingly also in the case of stacked covering platforms in such a way that the top and bottom surfaces 1c, 1c ', 1c''and 1d, 1d ', 1d''lie flat on top of each other. At the same time, it is ensured that transverse movements of the stacked hollow profile bars or covering platforms can no longer take place.
