Definitions

  • the invention relates to a length compensation arrangement for scaffolding, according to claim 1.
  • a telescopic frame can only be installed from one side of the building with at least three frame panels, since the telescopic frame must be installed between the two diagonal panels.
  • telescopic scaffolding fields are relatively expensive to buy and also bring with it an increased risk of accidents, since an unwanted retraction or extension of the telescopic covering during transport can lead to serious hand injuries.
  • the minimum length of a scaffold telescopic coating is always relatively long due to technical reasons.
  • the crossover of the framework fields is also not an optimal solution, since in this case the passage height is greatly reduced. Often a crossover of the framework fields is not even possible because, for example, outside console extensions would have to be penetrated by the mutual scaffolding.
  • the overlapping arrangement comprises at least a first metal rail and a second metal rail, each of which has a metal sheet running surface provided with substantially round through holes. At least a portion of the through holes is bounded in each case by an inner diameter spanning, bulging or bulging, circumferential hole edge.

  • the first gangplank and the second gangplate are fastened by means of a fastening bolt against displacement relative to each other in a direction parallel to their running surfaces sliding plane and secured against lifting each other releasably secured to each other.
  • the fastening bolt has a fastening head and a bolt shank which is penetrated both through a through hole of the upper, second gangplate and through a through hole of the lower, first plank protrudes, wherein the fastening head engages over a hole edge of that through hole of the upper, second plank and bears against this hole edge through which the bolt shank of the fastening bolt protrudes.
  • a length compensation arrangement with four scaffolding frames, two scaffolding floors and a length compensation element, according to the preamble of claim 1, is known from JP H07 34674 A known.
  • the length compensation element bridges a gap formed between the two spaced-apart scaffolding floors.
  • the JP 2008 050825 A discloses a length compensation element with an end-side end profile, two lateral end profiles and a covering connecting the two lateral end profiles and the end-side end profile covering.
  • the front end profile is equipped with attachment claws for connection to a scaffolding frame.
  • the length compensation element is arranged overlapping in a portion of its covering with a scaffold floor.
  • the present invention provides a length compensation assembly comprising at least first, second, third and fourth scaffolding frames, a first scaffold floor, a second scaffold floor, a length compensation element, a railing element and a scaffold coupling.
  • the first scaffolding floor is fixed, but releasably connected to the first and the second scaffolding frame and arranged between these scaffolding frames.
  • the second scaffolding floor is fixed, but releasably connected to the third and the fourth scaffolding frame and arranged between these scaffolding frames.
  • the first scaffolding floor is arranged in the vertical direction above the second scaffolding floor.
  • the length compensation element bridges a gap formed between the two spaced-apart scaffold floors, wherein the length compensation element has a first end profile assigned to the first stand bottom, a second end profile assigned to the second stand bottom and two lateral end profiles connecting the two end profile sections ,
  • the two front end profiles and the two side end profiles are connected by a covering, wherein the first end profile is equipped with at least two Einitatikrallen or two Ein motivation barnbrechungen for fixed but detachable connection to the second scaffolding frame, and the second end profile in section perpendicular to a plane formed by the pad is triangular in shape.
  • the length compensation element is arranged in the region of its second end-side end profile and at least in one, the second end-side end profile adjacent portion of its covering overlapping with the second framework floor.
  • the railing element has at least one upper railing rail, wherein the upper railing rail is equipped with at least one fastening element for attachment to the second scaffolding frame.
  • the railing element additionally has a substantially U-shaped railing bar, wherein the two ends of the U-shaped railing bar are connected to each other by the upper railing.
  • the upper railing is tubular and has an outer diameter between 45 mm and 55 mm.
  • the scaffolding coupling firmly connects the upper railing of the handrail, but detachably with the third scaffolding frame.
  • scaffolding frames in the context of the present invention not only the usual, known in the art scaffolding frames understood, but also corresponding constructs of two by cross struts (bars, U-bolt) interconnected modular scaffolding handles. So if in the present text and in particular in the claims of a "Scaffolding" the speech, so are not only Standard Gerüstrahmen meant, but all of two vertical pipes and connecting these tubes cross struts composite Gerüstrahmenmaschine.
  • the length compensation element as a central element of the length compensation arrangement according to the invention is equipped with the standard with standard scaffolding Ein rehabilitationkrallen or Ein rehabilitation barnbrechungen.
  • the length compensation element just like a standard scaffold floor, can be brought into engagement with the U-rails or connecting pins provided in conventional standard scaffolding frames and can therefore be installed quickly and easily during scaffolding construction.
  • the length compensation element is thus connected with its attached to the first end-side end profile connecting elements with a scaffolding frame. With its second end-side end profile and with a partial section of its covering which is adjacent to this second end-side end profile, the length-compensating element is arranged in an overlapping manner with the second framework floor, so it rests on this framework floor. Overall, this results in a very simple installation of the length compensation element in a framework. The length compensation element is simply hung on one side of the gap in the scaffolding frame and placed on the other side of the gap on the scaffold floor.
  • the first and the second framework floor are at least slightly offset from one another in the vertical direction, wherein the first framework floor is arranged above the second framework floor.
  • the first and the second scaffolding floor are located in a common scaffolding floor level, an oblique arrangement of the length compensation element would result, as this yes connected with its attached to the first end profile end fasteners with a scaffolding and placed on the opposite side of the gap on the scaffold floor becomes. Therefore, in this case, the length compensation element would have to overcome a height difference corresponding to its own height H, which would lead to an increased risk of tripping, in particular in the region of the second frontal end profile.
  • first and the second scaffolding floor are arranged offset from one another in the vertical direction and in particular substantially offset by the height H of the length compensation element, the first scaffold floor being arranged above the second scaffold floor, this results in a further advantage.
  • first scaffold floor is arranged essentially around the height H of the length compensating element in the vertical direction above the second scaffold floor, then the length compensating element extends in a common plane after being connected to the scaffolding frame with the first scaffold floor.
  • the length compensation element lies on the second framework floor and overlaps with it in a sufficient area. Due to the special design of the second front-side end profile, which has a triangular shape in section perpendicular to a plane formed by the covering, there is virtually no risk of tripping in the area of the second framework floor either.
  • the covering of the length compensation element is preferably a profiled covering.
  • a profiled covering fulfills all the standards of system scaffold coverings in terms of skid resistance and load-bearing capacity.
  • the first and the second framework floor are arranged substantially at right angles to one another.
  • a substantially rectangular arrangement of the two scaffold floor to each other results in a uniform over the entire width of the length compensation element overlap with the second scaffold floor.
  • the scaffolding floors can be arranged at almost any angle to one another, wherein the boundary areas of the arrangement relative to each other must, of course, make technical sense to the skilled person. If the two scaffolding floors and thus also the two sections of the entire scaffolding, between which a gap results, are arranged at an angle deviating from 90 ° relative to one another, the functionality of the present invention nevertheless remains intact.
  • the relatively large bandwidth of expansions of the resulting scaffolding gaps is taken into account that the length compensation element in different sized lateral extent, that is sized differently sized in the direction of the first end-side end profile to the second end-side end profile is made.
  • the individual lengths are staggered so that a suitably dimensioned length compensation element is available for every imaginable gap up to almost the length of a standard scaffold floor.
  • the widths of the length compensation element are advantageously adapted to the usual standard frameworks widths and correspond substantially to the usual widths of the scaffold floors.
  • the two end-side end profiles run substantially parallel to one another, the two lateral end profiles run essentially parallel to one another and the covering which connects the end-side end profiles and the side end profiles is formed substantially rectangular.
  • the rectangular length compensation element when using the rectangular length compensation element to bridge a gap between substantially at right angles or in a slightly deviating from 90 ° angle relative to each other arranged scaffolding sections results in a secure bridging the gap with a uniform overlap region and thus a secure support of the length compensation element on the second framework floor.
  • the length compensation element consists of metal and the covering is formed of a metal sheet.
  • This embodiment provides a stable, difficult to deform element that can be easily manufactured at the same time.
  • the length compensation element can be designed with multiple creases in the region of its lateral end profiles.
  • the covering is formed from a profiled metal sheet.
  • the metal sheet according to a further preferred embodiment, a plurality of substantially round through holes, wherein at least a portion of the through holes each bounded by an inner diameter spanning, beaded, circumferential hole edge.
  • the metal sheet forming the covering has no through holes, no elevations and no depressions in its regions adjacent to the end-side end profiles.
  • the lack of through holes, elevations and depressions ensures a secure stacking. This can be further improved, even if no such through holes, elevations or depressions are provided in the regions of the covering adjacent to the lateral end profiles.
  • the hole diameter of the through holes is about 14 mm, so that conventional bolts or special screws can be used to secure the length compensation element in the overlapping with the adjacent scaffold floor section.
  • an additional fastener with which the length compensation element and the second framework floor are fastened together and so slipping or lifting of the length compensation element is additionally reliably avoided.
  • Such a backup is required especially in the case of high wind loads.

  • the length compensation element lies on the second framework floor and overlaps with it in a sufficient area. In the region of the second front-side end profile, only a height difference corresponding to the height H of the length-compensating element must be overcome relative to the second framework bottom, which already leads to a reduced risk of tripping, which is further reduced by the special design of the second end-side end profile.
  • the distance between the two scaffolding floors in the vertical direction is ideally adapted to the height H of the length compensation element. If the length compensation element has a height H of 40 mm, then in the context of the present invention it is particularly preferred if the first framework floor is arranged in the vertical direction by approximately 40 mm above the second framework floor.
