Definitions

  • the invention relates to a collapsible facade scaffold with at least four vertical supports consisting of individual, separable support elements, in which at least certain support elements have fastening positions for floor slabs and for railing elements which extend essentially horizontally.
  • Such facade scaffolding is widely used to be erected on the facade of a building in order to carry out outdoor work, e.g. to be able to paint.
  • Facade scaffolds of this type are generally constructed by successively erecting the individual scaffold levels, the individual support elements of the vertical supports of a first scaffold level generally ending just above a base plate belonging to a second scaffold level located above. This upper end of the support elements is then coupled by the fitter to the lower end of the support elements for the second scaffold level, in particular by means of a plug connection.
  • one or more substantially horizontal railing elements are attached to the support elements in that (the second) scaffold level in which the fitter is during the last-described working step. These railing elements serve to reduce the risk of falling.
  • the base plate belonging to the third scaffolding level lying above the second scaffolding level is removed from Fitter coupled overhead with the previously attached support elements.
  • the scaffolding is additionally stabilized with cross and / or diagonal struts when erecting the individual levels.
  • An object of the invention is to provide a dismantled facade scaffold of the type mentioned at the beginning and a method for assembling and disassembling the same, in which the risk of accidents during assembly or disassembly is reduced to a minimum, in particular the assembly and / or disassembly should be economically feasible in a simple manner.
  • an inventive facade scaffold in that when the scaffold is erected there is at least one fastening position of a support element provided for a railing element above a fastening position of the same support element provided for a base plate, and that, for example, when the scaffold is erected only on one side Fastening position of a support element fixed railing element can be pivoted about at least one axis running essentially horizontally through the coupling point between the support element and railing element.
  • the object is achieved in that the railing elements belonging to a scaffolding level are mounted in time in front of the floor plates belonging to the said scaffolding level, a railing element having one end with a mounted support element in the area of the scaffolding level to be erected and then with the other end is coupled to a further support element which has not yet been mounted, whereupon the further support element is mounted by pivoting the railing element into a horizontal position.
  • a particularly simple assembly and disassembly of the scaffold according to the invention is made possible according to the invention in that a railing element which is only fixed on one side to a support element can be pivoted about at least one axis running essentially horizontally through the coupling point between the support element and the railing element.
  • the railing element can thus be pivotably attached to an already assembled support element and then pivoted upward into its final horizontal position with the aid of a further support element that is still to be installed.
  • the railing elements it is also possible for the railing elements to have one end firmly connected to a support via a hinge connection. element are connected so that this connection does not have to be made or released by the fitter, since the railing element and support element form a unit.
  • This embodiment has the advantage that the number of individual parts to be moved during assembly or disassembly is reduced.
  • the joints of the support elements of the vertical supports are no longer provided just above the base plates, as in the prior art, but rather above the base plates to the extent that a railing element at the upper end region of the support elements is at a sufficient distance from the fixing position of the base plate can be assembled.
  • This makes it possible to assemble the railing elements of a scaffold level in front of the floor slabs belonging to this scaffold level.
  • the side protection created by the invention and always present is particularly advantageous because during assembly and disassembly, individual parts of the scaffolding must be picked up or handed in by the fitter, the fitter necessarily having to lean a little outwards, which, without side protection, entails a not negligible risk of falling would require. It should also be borne in mind that assembly and disassembly also take place in unfavorable weather conditions, for example in strong winds or frozen floor slabs. In this case, the additional increased risk of falling, the side protection according to the invention has a particularly advantageous effect.
  • the assembly of a scaffolding according to the invention can be accomplished, for example, as follows:
  • One end of a railing element is coupled to an already mounted support element in the area of the scaffolding level to be erected, at which point the base plate of the scaffolding level to be erected has not yet been assembled.
  • the other end of the railing element is then coupled to a further support element which has not yet been installed, whereupon the further support element is mounted by pivoting the railing element.
  • the base plate belonging to the erecting scaffolding level can then be installed, which can subsequently also be entered by the fitter, since the associated railing element was already installed in front of the base plate.
  • Disassembly can be carried out in the reverse order.
  • the distance between the fastening position of a support element provided for the railing element and the fastening position of the same support element provided for the base plate is between 70 cm and 130 cm, in particular approximately 100 cm.
  • the support element can extend downward beyond the fastening position provided for the base plate, for example over a length of between 60 cm and 120 cm, in particular about 90 cm.
  • the above-mentioned dimensions ensure that the railing element can be fastened at a sufficiently great height above the base plates to be mounted, so that effective side protection is achieved, for example at a height of 100 cm above the respective base plate.
  • the assembly is simplified in that the railing elements can be attached to the fastening positions of the support elements provided for this purpose without the use of a tool.
  • the hammering of a wedge which is often necessary in the prior art, is therefore superfluous.
  • the coupling between the railing element and the supporting element is preferably designed such that it can be released again without the use of a tool. In this way, disassembly is simplified and accelerated.
  • a particularly simple coupling between railing elements and support elements is obtained when the railing elements are in the fastening positions provided for this purpose Support elements are hooked. It is again advantageous if the hanging connection is equipped with a safety device to prevent unintentional loosening, in order to ensure that when a horizontally directed force is exerted on a railing element, as occurs, for example, when the fitter leans against the railing element, the Railing element is reliably connected to the support element.
  • the safety device mentioned is preferably designed in such a way that it is achieved solely by the coupling of the railing element and the support element, without having to actuate separate devices for this purpose or additional actions have to be carried out by the fitter.
  • the hanging connection is preferably implemented by means of an extension piece which extends substantially perpendicularly to the support element and is fixedly connected thereto, and a tab which is provided at the end region of the railing element and can be coupled to the attachment piece.
  • the extension piece is preferably designed as a stamped part, which can be welded to the support element, for example. In this way, the manufacturing costs can be kept to a minimum, since the punching process can be carried out with little economic effort.
  • the extension can, for example, be made substantially flat, although it must of course have a certain strength in order to be able to withstand the forces that occur.
  • this has at least two projections on its top and bottom sides offset from one another.
  • the lug of the railing element can be threaded onto the extension piece with the railing element aligned perpendicular to the supporting element, with pivoting movements being carried out, the lug being moved over a projection of the extension piece with each pivoting movement.
  • the flap is moved alternately over the projections provided on the top and bottom of the extension piece by successive counter-rotating swiveling movements.
  • the tab is designed as an elongated hole extending in the longitudinal direction of the railing element, since in this case the tab can be plugged onto the extension piece by executing an essentially linear movement if the support element and the railing element form an angle that is less than 45, for example ° is.
  • Such an angle includes the support element and the railing element in that stage of assembly or disassembly in which the railing element has a free end, that is to say an end that is not coupled to a support element, and the other end is to be connected to or detached from a support element .
  • the coupling point between the support element and the railing element is, for example, approximately 3 m above the base plate on which the fitter is standing, so that it is advantageous if the corresponding coupling can be produced or removed by a simple linear movement.
  • two fastening positions of a support element are located above the fastening position of this support element provided for the base plate. So two country elements are provided at different distances from the base plate to be retrofitted, which increases the side protection to be provided.
  • the distance between the fastening position provided for the second railing element and the fastening position provided for the base plate is, for example, between 30 cm and 70 cm, in particular approximately 50 cm. It is therefore possible, for example, to provide two railing elements at a distance of 50 cm and 100 cm from the floor slab.
  • the number of parts to be moved during assembly or disassembly can be reduced in the latter case in that the two railing elements belonging to a supporting element are connected to one another in an articulated manner.
  • This articulated connection enables the two railing elements to be pivoted together upwards into their horizontal position in the manner already described above. Instead of two individual railing elements, however, only one part comprising both railing elements has to be moved, and additional stabilization of the overall framework is achieved by the articulated connection of the two railing elements.
  • the total length of a support element that is effective when the scaffold is erected can be between 180 cm and 220 cm, in particular approximately 200 cm.
  • the total length of a support element that can be used in the lowest scaffold level when the scaffold is erected can be between 280 cm and 330 cm, in particular approximately 300 cm, such a support element having two fastening positions for two base plates to be arranged in different scaffold levels.
  • the number of parts to be moved during assembly or disassembly can additionally be reduced in that two parallel supporting elements, which come to rest on a narrow side of a base plate in particular when the scaffolding is erected, are firmly connected to one another via a cross strut.
