Definitions

  • the invention relates to a support for a space structure with a fastening device for securing a railing device to the support and a connection arrangement for a railing device comprising at least one support for a space structure and a railing device, which is fastened by means of a fastening device to the support and further relates a method for securing a railing device by means of a fastening device to a support for a space structure.
  • a particularly simple fastening construction is for example from CH-A-439 679 known.
  • This relates to a scaffolding with vertical support frame, the vertical support tubes are provided with U-shaped Einsteckösen, in which are bent at right angles bent down insertion ends of handrails of railing frame. These railing frames are not secured against lifting upwards, which is not tolerable under safety aspects.
  • Another banister attachment is from the FR-A-25 16 141 known.
  • scaffolding frames are provided with vertical stems to which transverse bolts extending away are attached. These have at their free ends upwardly projecting cams, so that these bolts form a kind of hook.
  • the ends of a double railing or a railing frame are mounted, the upper two end tabs are provided for this purpose with downwardly open receiving openings, which form a kind of contrast hooks.
  • the lower two end tabs are provided with elongated holes extending in the vertical direction, of which a slot with a pivotable about a horizontal axis trigger guard against removal in the direction of the bolt of the associated hook one of the scaffolding posts is securable. These railings are also not secured against lifting up.
  • the FR-A-25 16 141 also discloses L-shaped longitudinal bars which be used for connecting and attaching two adjacent scaffolding frame on which L-shaped supports are supported, which are designed with a crossbar on which can be supported in an intermediate position between the cross members of adjacent scaffolding frame scaffolding planks made of wood.
  • These L-longitudinal bars have at their L-leg two vertically spaced end legs and at their perpendicular from the L-leg extending away the other end a third end leg.
  • This third end leg has a downwardly open hook which can be hung on an upwardly open hook bolt of the stems one of the frames.
  • the third end leg also has a hook-shaped swivel bracket, which is pivotable about a transverse axis and which pivots under hooks on the hook bolt third end leg by gravity under the hook bolt and in this way allows a vertical lift-off at this end of the L-longitudinal bar.
  • this swivel bar is attached to the end of the L-longitudinal bar pivot bracket, an increased risk of injury when handling the L-longitudinal bar.
  • a first main group concerns constructions in which the cross-country facilities are positively locked by clamping forces secured against lifting from the brackets of the supports.
  • this U-shaped wedge boxes are attached to the vertical scaffolding tube stands with their thighs, in which perpendicular bent down tabs of railings are inserted and fixed there by means of a wedge. This must be hammered in order to achieve a pressing of a tab of a railing against the tube stand or two hinged in the same wedge box tabs of two railings against each other and against the tube stand, thus the handrail or against vertical lifting upwards to fix.
  • the wedges To dismantle the framework, the wedges must be knocked out with a suitable tool, so that the construction and dismantling of such scaffolding is comparatively complicated only by means of a tool.
  • Such constructions are for example from the DE-A-27 57 189 , of the DE-A-38 32 480 , of the DE-A-31 08 020 , of the DE-A-198 27 284 and the DE-U-20 2004 007 550 known as the "Layher Flash Scaffold System".
  • the wedge boxes can also be releasably connectable to the scaffold stems, such as in the WO 02/066765 A2 disclosed.
  • a second major group of railing attachment constructions relates to such solutions in which the railings are purely positively connected to the scaffolding posts.
  • transverse bolts projecting transversely to their longitudinal axes are fastened to the vertical framework supports for this purpose, on which the railings provided with matching through holes are attached.
  • the first subgroup can be divided into two further groups:
  • cylinder bolts which have at their free ends a vertical slot in which a Kippteredlasche is pivotally mounted about a horizontal transverse axis.
  • the Kippuxlaschen To attach a railing to the scaffold stems the Kippstattlaschen must be transferred to a threading the provided with matching through holes railing tabs on the cylinder bolt enabling unlocking. After threading and attaching the perforated railing tabs the respective Kippstattlasche must be converted back into a vertical locking position, which is basically achieved by gravity supported by itself.
  • a second group of the first subgroup of the second main group relates to similar constructions, which are therefore based on the same basic principle, namely to attach to scaffolding posts transversely projecting bolts on which are fitted with matching through holes railings.
  • these constructions such as those from the DE-A-196 33 092 or the EP-A-1 262 611
  • the inner contour of the through holes of the railing and the outer contour of these receiving bolts are designed coordinated so that an attachment of the railing on the bolts only obliquely from below, ie from the underlying scaffold layer, is possible by the railing in an angle of less than 90 degrees to the longitudinal axis of the scaffold stems from below is placed on the bolt. Subsequently, by pivoting the railing upwards into a horizontal use or installation position at the same time a positive locking of the railing is achieved relative to the scaffold post also in the direction of the longitudinal axis of the Aufsteckbolzen. Horizontal attachment of railings from the same scaffold level is not possible with these designs.
  • DD 90 210 A Another construction relating to a railing attachment, which can be assigned to a second subgroup of the second main group, in which the railings are also purely positively connected to the scaffolding stems, is from the DD 90 210 A known.
  • a tab is welded to a pipe stem, profiled to form a receptacle for vertical Gelanderelfn L-shaped and bent upwards and is open at the top.
  • this is provided with a vertical slot.
  • Through this vertical slot protrudes a nose of a pivotable about a horizontal pivot axis case-latch, which is rotatably mounted on a horizontal bolt.
  • the bolt is welded by bridging the vertical slot of the L-strap.
  • the case latch To remove the two railing strips or possibly only one of the railing strips, the case latch must be pivoted by hand about its pivot axis upwards in a removal of the respective railing vertical upward enabling release position, whereupon the respective railing vertically upwards from the can be lifted out by the L-strap formedatomicrry.
