Definitions

  • the present education is in the field of scaffolding and relates to a Slessnesszzmaschinendibi.
  • the present invention is based on the problem of providing a device that facilitates working on the ground, which is easy to set up and also offers the greatest possible degree of adaptability to the practical requirements.
  • a riser set comprising two joint conductors each having at least two conductor sections having rungs, and a joint arranged therebetween, and a bottom which can be fastened between the two joint conductors in an upright orientation thereof to form a framework.
  • the climbing attachment according to the invention has two known articular conductors. These have two conductor sections, each with two parallel extending spars and arranged therebetween, extending in the horizontal rungs. Between these two conductor sections a joint is provided. Accordingly, the articulated conductor of the conductor section can be extended to a relatively long conductor by pivoting the joint so that the two conductor sections are aligned in extension to one another.
  • the ladder can be used for this purpose. It is also possible to form a ladder by pivoting the respective ladder sections, which stands without leaning against another object and carries a craftsman. By further pivoting of the conductor sections to each other they can be placed against each other, so that generates a relatively compact conductor with half the height of the swung ladder becomes. Sometimes such a ladder is necessary in order to work in confined spaces above the ground.
  • the compact arrangement of the ladder sections also allows a space-saving storage of Sierezzieresatzes.
  • the climbing attachment according to the invention comprises two of the articulated conductors described above. These articular conductors preferably have only one joint. It is also conceivable to use three or four articular conductors. However, the articulated conductor is preferred with a single joint and two equally long conductor sections.
  • the two articulating ladders of the climbing attachment can be set up in vertical orientation, parallel to each other in the vertical direction to form a scaffold.
  • the individual articular conductors can in this case in the pivoted position of the conductor sections, i. be provided with maximum length, or with mutually parallel conductor sections.
  • the climbing attachment has a bottom which extends in such an orientation of the mutual articular conductors between them and can couple them together to form a framework comprising the at least two joint conductors and the framework floor.
  • This scaffold floor is in each case at the end on the rungs of the same height of the two articular conductors. This makes it possible to train the climbing attachment as a scaffold.
  • the climbing attachment comprises transverse and diagonal struts, which can be attached to the mutual articular conductors.
  • the sprouts of the joint conductors in a known per se inside hollow, for example, formed by a hollow rectangular or a hollow square profile. Through these hollow sprouts extend threaded rods that extend beyond the ladders in the longitudinal extent of the rungs on both sides.
  • Nuts preferably nuts that can be screwed by hand, such as wing nuts or thumbscrews, can be screwed onto the threaded studs of the threaded rods projecting above the ladders.
  • the diagonal braces prevent displacement of the parallel extending ladder in the manner of a parallelogram.
  • the cross struts are on identical height of the ladder and thus ensure the position of the ladders to each other in the vertical.
  • the Steigzzsatz should have at two different levels cross struts, preferably in each case on both outer sides of the ladders.
  • a plurality of diagonal struts should be provided, preferably provided in the manner of a cross diagonal struts.
  • This cross is preferably formed by diagonal struts which are struck on opposite sides on the ladders.
  • the transverse or diagonal struts are preferably formed from hollow round profiles, which are each flattened end and provided with a bore for passing the threaded rod.
  • a threaded rod in the sense of the present invention is also an elongated profile which has a threaded portion only at its end sides. This can be cut directly on the pole.
  • the threaded rods are designed such that the attachment points can be mounted on at least one of the transverse struts and at least on one of the diagonal struts on the same threaded rod on the associated joint conductor.
  • the possibility is created to mount a cross member at that point end to the ladder on which the end of a diagonal strut is fixed to the ladder.
  • the development allows a relatively compact construction of the framework.
  • the climbing attachment according to the invention has, for example, a joint guide with seven rungs on each side of the joint.
  • a joint conductor is referred to as 2 x 7 joint conductor.
  • a framework with a total height of about 4 m can be created.
  • the ground is here regularly for safety reasons about 3 m above the ground; the overlying longitudinal portion of the respective articular conductors is used for the attachment of railing struts, which serve to secure a person standing on the ground.
  • a support of the present invention which projects beyond the framework in its transverse and longitudinal extent on the outside and having a widened foot.
  • the foot is preferably articulated to the spar forming the post, preferably with the interposition of a length compensating means, for example a thread screwed into the post, which can be countered on the post.
  • a length compensating means for example a thread screwed into the post, which can be countered on the post.
  • the upright framework can be additionally supported at points that are regularly outside the support points of the articular fibers.
  • the bases of the articular conductors are usually formed by the spars on the outside by superior widened feet. These feet are located within a rectangular area, which are formed by the usually provided on each individual spar, outwardly projecting obliquely downwards in the longitudinal and transverse directions supports.
