Definitions

  • the invention relates to a scaffolding covering for scaffolding according to the preamble of claim 1.
  • system scaffolds used to be widely used tubular steel coupling frames repressed.
  • System frameworks are characterized by the fact that almost all the individual parts of the scaffolding required for assembly can be assembled without complex connection techniques can. In general, these are form-fitting Connections (plug connections, hanging devices, etc.) used to support the vertical and horizontal elements connect with each other. This also applies to them Scaffolding coverings from system scaffolds, which are in the form of Scaffolding floors not only the walking and working area of the Form scaffolding, but at the same time the stiffening Effect against horizontal stress on the scaffolding provide.
  • This Scaffolding components can include vertical scaffolding elements, e.g. Be scaffolding posts with corresponding connection elements; in usually serve to secure the scaffolding coverings so-called crossbars, on which the scaffolding coverings are placed or hooked into the scaffolding coverings.
  • the Supporting elements of the front carrier elements Scaffolding decking designed differently. So are in certain commercial embodiments holes in the end support elements provided, in the vertical pins attached to the crossbars can be inserted. In other designs there are claws or slotted strips on the attached end support elements, by means of which the Scaffolding covering in, for example, U-shaped cross bars can be hung.
  • Embodiments are the special shape of the slotted strip.
  • the slotted strip in the In general, either extruded Aluminum profiles or by cold profiling or as Stamped bent part manufactured support elements used.
  • These slotted strips usually with their comparatively narrow suspension slot over the entire
  • the width of the toppings spread out Hook-in slots relatively quickly with dirt and mortar, so that it is difficult to hang up the scaffolding coverings.
  • Support elements with the mounting holes listed above or hanging claws are therefore an advantage in handling.
  • the carrier elements with hooking claws are So far, however, it is considerably more expensive to manufacture because the Claws manufactured separately and then welded or be riveted. This procedure is not only very complex, but also includes a number of possible Sources of error.
  • the object of the invention is therefore a scaffold covering propose, the support element of a simple manufacture allowed while ensuring good handling.
  • This task is based on a scaffold covering type mentioned in the introduction by the characteristic features of claim 1 solved.
  • the carrier element comprises an extruded profile, the Press direction perpendicular to the tread of the scaffolding covering stands.

  • This plug element can in turn be advantageous Embodiment from an extruded profile with a appropriately chosen, for example hook-shaped Cross section can be manufactured.
  • An additional fastening of the plug element is on the one hand useful to captive the plug element with the Carrier element and thus with the entire scaffolding publisher connect.
  • the appropriate training Connection for example by welding or gluing, the load bearing and thus the load-bearing capacity of the resulting resulting scaffolding can be improved.
  • a support element at least partially enclosing support part which in turn ends can be hook-shaped and the production as Extruded profile is accessible.
  • Such a support part can for example, reach under the carrier element so that it at least partially on the front, the bottom and the Back of the support element related to the built-in Condition in the scaffolding covering.
  • corresponding projections are also molded into the extruded profile be used to form a hanging claw only a groove has to be worked in afterwards.
  • This groove can be retrofitted, for example, by milling the projections provided for this purpose of the extruded Blanks are attached.
  • This straight milling Groove is an unproblematic process that is easy can be done fully automatically.
  • the carrier element is advantageously designed such that that it spanned the full width of the scaffolding deck extends. This creates the connection with the covering element simplified and good stability guaranteed.
  • a support element for an end face of a scaffold covering can however, also include several sections that are side by side the corresponding covering element can be arranged.
  • a Such a construction has the advantage, for example, that scaffold coverings of different widths with the different wide support elements with the corresponding different number of sections can be provided can, which are each the same.
  • the individual sections can be developed in a further development Practical embodiment, e.g. with the help of a Plug connection to be connected. If necessary, this can Plug connection through additional fastening measures, e.g. supported by welding, gluing, riveting, etc. become.
  • Each support element can be equipped with several support elements Connection to the system framework, e.g. the appropriate shape or corresponding attachment points in the Extruded profile can be specified. Especially in the case of one single, essentially spread across the width of the Supporting element extending scaffolding covering, it is recommended at least two spaced apart support elements to provide good tilt stability in built-in To achieve state.
  • the recesses are preferably made in such a way that the remaining material in the form of reinforcing Profiles exist to the bending stiffness of the To improve support element.
  • the carrier element lateral extensions attached, by means of which the Carrier element are anchored in the corresponding covering element can.
  • Such extensions are next to one Welded connection also joining techniques for connecting the Carrier element can be used with the covering element. So can for example, the support element with these side Extensions in corresponding hollow profiles of a covering element inserted and riveted or screwed there.
  • aluminum can be Process the extrusion process well and on the other hand it points light weight on what the manageability of the finished Scaffolding to good advantage.
  • the invention combines in the manufacture of scaffolding coverings the advantages of extruded carrier elements with the Advantages of the multi-part, composite support elements.
  • the advantages extruded profiles are that if necessary entire support element can be formed in one piece, without another profile and in particular none Fastening measures such as welds, or others Joining techniques required to connect the individual parts are.
  • the advantages of multi-part training Support elements such as easier attachment, less Soiling tendency as well as lower weight can a scaffolding covering according to the invention also without material-intensive mechanical processing realized become.
  • a carrier element 1 is shown, which for Connection with a covering element 2 is determined.
  • the one out Carrier element and covering element 2 formed scaffolding covering 3 can then into a schematically illustrated crossbar 4 of a system scaffold.
  • the carrier element 1 is according to the invention as an extruded profile formed, the pressing direction z perpendicular to x / y plane lies by a tread 5 of the Covering element 2 is defined.
  • the carrier element 1 is therefore with a height H of one corresponding, not shown extruded profile cut off using a conventional separation process.
  • the hooking claws 6 initially only be molded as profile projections.
  • the Hook-in grooves 7, through which the profile projections Hanging claws 6 must subsequently e.g. be machined. Since all hook-in grooves 7 however aligned with each other on a straight line are arranged, this process can be done in a simple manner and in particular fully automatically with the help of a Carry out milling machines. The loss of material is limited refer to the volume of the groove and is therefore extreme low.
  • the further recesses 9, 10, 11 result in a Formation of the support element in the form of a hollow profile the advantages listed above in terms of Material consumption and weight.
  • the walls 12, 13 are preferably arranged so that they are a exert a stiffening effect on the carrier element 1.
  • This stiffening structures are not shown Version with the trapezoidal, stiffening walls 12, 13 limited, but depending on the application can be varied. For example, rectangular shapes are also or, for particularly high loads, would also be Honeycomb structures conceivable.
  • the carrier element 1 is laterally with extensions 14, 15 provided that in lateral hollow sections 16, 17 of Covering element 2 can be inserted.
  • the grooves 19 serve as well as the lateral extensions 14, 15 in addition as stiffening structures that the Overall stability of the carrier element 3 and thus of the Carrier element 1 and the covering element 2 emerging Improve scaffolding deck 3 significantly.
