Definitions

  • the invention relates to an industrial scaffold with vertical supports, which can be connected to each other by means of horizontally extending latch, wherein in the bolt to create a walk-in work surface pads are ein ⁇ suspended, which extend in a horizontal plane.
  • Such industrial scaffolds are often used in practice to maintain or create industrial plants, especially chemical plants. Also in shipbuilding or in the maintenance of ships industrial scaffoldings are used. In many of these applications, the problem arises that complex contours, which have only a few straight surfaces, must be scaffolded. In particular, it is often necessary to convert pipes or pipe systems, which is particularly difficult if - which is generally desirable - the working surface of the scaffold should be brought as close as possible to the surfaces to be converted.
  • An object of the invention is to provide an industrial scaffold of the type mentioned at the outset, by means of which largely seamless work surfaces can be created while maintaining the lowest possible number of different parts.
  • edge regions of the coverings in the suspended state overhang over the body of the coverings such that a possibly parallel to such edge region extending latch is partially covered by this edge region.
  • the invention is thus based on the surprisingly simple idea of modifying certain edge regions of the coverings in such a way that they partially cover a bar, preferably approximately halfway, extending parallel to such an edge region, which leads to a situation between the cover and the bar no annoying gap can arise. Furthermore, if mutually parallel deposits are arranged on both sides of a bar whose edge areas facing the bar are configured according to the invention, it is achieved that these border areas almost touch one another or only form a very small gap between them, so that the bar of each of the two border areas each is covered about halfway. In this way, a virtually continuous working surface without any gap or step is created in the area of the bolt, wherein the bar covered by the inventively designed edge regions from above, as good as can no longer be seen. A correspondingly continuous work surface without any gap is also ensured according to the invention when no bolt is located between the adjacent coverings, since the overhanging edge regions of the coverings almost adjoin one another independently of the presence of a bolt.
  • the main body of the coverings according to the invention generally extends in the same plane as the bolts, wherein the overhanging edge regions are arranged just above this plane, so that no collisions can occur between these edge regions and the bolts.
  • the body of the pads are dimensioned so that they can be inserted between the bars without that they abut the bars.
  • the coverings according to the invention may have a rectangular shape and have on their front sides hook elements for hooking in a latch, so that these hook elements and any other frontally provided on the coverings support elements are essentially responsible for the Kraft ⁇ transfer of the coverings on the bars.
  • the front sides of the coverings are in contrast to their long sides no or only slightly overhanging edge regions, since the coverings on the construction side always anschlie ⁇ Shen on a bar, so that here no gaps can occur between frontally adjacent pads. Such gaps are more likely to be filled by the mandatory batches.
  • the longitudinal sides of the coverings are provided with edge regions which project beyond the invention. This results in an advantageous manner that longitudinally adjacent pads form no significant gap between them, regardless of whether there is a bar between the pads or not. Rather, the overhanging edge regions largely adjoin one another directly and thus form a continuous surface, wherein they either cover a bolt present between the coverings or - in the absence of such a bolt - cover the cavity provided for such a bolt.
  • additional bolts can also be provided, which in turn extend between auxiliary bolts, base bolts and / or vertical supports.
  • Base bars are therefore always arranged between two vertical supports, whereas additional bars with their frontal coupling areas can be coupled in any manner with vertical supports, base bars or other auxiliary bars.
  • the additional bolts extend perpendicular to those bars to which they are attached, with all the bars of a working plane are in the same plane.
  • the provision of the aforementioned additional bolt makes it possible to adapt the industrial scaffolding according to the invention very variably to the most varied contours and, in particular, to provide comparatively small recesses in the working surfaces to be created, without the need for a large number of different parts.
  • the provision of the aforementioned auxiliary bars makes it possible, in particular, for a number of first coverings to be present in a walk-on work surface which are aligned parallel to one another, with second coverings extending perpendicular to the first coverings continuing to be present. Corresponding examples will be explained below in the context of the description of the figures.
  • the base and additional latches have identical cross sections and also have identical frontal coupling sections.
  • the production cost is minimized, and also it is possible to use the existing bars versatile both as a basic and as an additional bar, since there are virtually no differences between basic and additional bars.
  • the only relevant differences are in the length of the bars, but quite cases are conceivable in which basic and additional bars undereinan ⁇ the same lengths.
  • the bars according to the invention which can be used both as a basic and as an additional bar, can be coupled either as a base bar with vertical supports or as an additional bar with other bars, it is useful aus ⁇ form the frontal coupling sections of the bolt so that they, for example suitable for attachment to rosettes connected to the vertical supports, in which case separate coupling elements must be provided for the attachment of an additional bolt to a further bolt, which are suitable to a bolt with a connect frontal coupling portion of an additional bolt.
  • Derar ⁇ term coupling elements can then be attached along a bolt at any point.
  • the coverings according to the invention are preferably present in different sizes adapted to a grid dimension, the spacing of the longitudinal axes of adjacent vertical supports being an integer multiple of the grid dimension.
  • the grid may for example have a length of 25 cm or any other lengths. Accordingly, in this case, the bars which can be used as basic and additional bars also exist in sizes adapted to the grid dimension, so that the entire system can be used with a maximum possible degree of variability with a minimum number of parts to be kept.
  • the longitudinal extension of the coverings can amount to slightly more than an integer multiple of the grid dimension, so that the hook elements can completely overlap the latch. Such an overlap effectively prevents a relative movement of the linings perpendicular to the bars on which the linings are suspended. If the longitudinal extension of the coverings, including the front hook elements, would only be an integer multiple of the grid dimension, it would only be possible to rest on the latches, but not to be suspended, so that the mentioned relative movement would not be prevented in a disadvantageous manner.
  • this multiple also includes the simplicity of the pitch.
  • the longitudinal extent of the coverings without the end hook elements is preferably slightly less than an integer multiple of Ras ⁇ term rivets, so that hanging two frontally adjacent pads in a common bar is possible without an already hinged pad prevents the attachment of another covering.
  • the width of the coverings of the invention including the überkragen ⁇ the edge regions may be equal to the one, two or three times grid. Due to these dimensions it is achieved that longitudinally adjacent pads form virtually no gap between them.
  • recesses for wedges can preferably be present in this case, with which the bolts can be fastened to the vertical supports. Such recesses are expediently provided exclusively in those sections of the edge regions which are located in the immediate vicinity of the vertical supports and thus of the wedges.
  • the width of the coverings may also be somewhat less than the one, two or three times the rake dimension, so that the wedges mentioned fit between two coverings adjoining one another along the longitudinal side. In this case, then a slight gap between adjacent coverings is accepted.
  • FIG. 1 shows a three-dimensional representation of an industrial framework according to the invention adapted to a specific application
  • FIG. 4 is a plan view of the working surface of the scaffold according to FIG. 1, FIG.
  • FIG. 5 is a plan view of another, according to the invention.
  • FIG. 7 is a three-dimensional view of a plurality of mutually parallel pads of FIG. 6, which are mounted in a latch,

  • the framework consists of a plurality of vertical supports 10a to k, which consist in the illustrated application of several nested parts, as known from the prior art.
  • the vertical supports 10a to k are provided with equidistantly spaced apart rosettes 12, in which inter alia latch 14 are suspended, which adjacent vertical supports 10a to k miteinan- connect.
  • diagonal supports 16 are also provided in a known manner, which are also in the rosettes 12 can be suspended.
  • handrail elements 18 for securing work planes can also be suspended in the rosettes 12.
  • a comparatively small, only rectangular lower working plane 20 and a larger and more complex formed upper working plane 22 are created. Both working planes are each formed by a plurality of coverings 24, the lower working plane 20 consisting exclusively of six mutually parallel coverings 24.
  • FIG. 1 illustrates that an industrial scaffold according to the invention can be adapted very individually and precisely to the respective shapes of the tubes 2, 4 and the walls 6 to be converted without appreciable gaps between the linings 24 and the tubes 2 occurring here, for example. Furthermore, the pads 24 are designed so that no gaps between them, which will be explained below in connection with FIGS. 2 and 3.
  • Fig. 2 shows in section two mutually parallel pads 24, between which a bolt 14 is arranged, the longitudinal extent of which extends parallel to the longitudinal sides of the pads 24.
  • the coverings 24 each consist of a base body 26, which has a comparatively thin, horizontally extending, accessible plane, from which stiffening elements which are stable in the outer regions extend substantially perpendicularly downwards. These stiffening elements are arranged exclusively on the longitudinal sides of the coverings 24 and not on their end faces.
  • the stiffening elements are located substantially in the same plane as the bar 14, which means that the framework parts have to be dimensioned such that the stiffening elements and the bars 14 do not collide with one another when mounting or demounting the framework ,
  • the horizontally extending plane of the main body 26 has for reasons of material and weight savings openings 28, which simultaneously serve as anti-slip elements and whose shape spielmati from Fig. 6 is more apparent.
  • the longitudinal sides of the coverings 24 are each provided with overhanging edge areas 30 which protrude laterally beyond the base body 26 and are located above the plane in which the latches 14 extend when the framework is mounted. In this way it is achieved that two mutually facing overhanging edge regions 30 of two adjacent bars 24 largely overlap a bar 14, so that only a small gap is formed between the two overhanging edge regions 30.
  • the provision of overhanging edge regions 30 in accordance with FIG. 3 also permits the formation of work surfaces without disturbing gaps between adjacent linings, since the overhanging edge regions 30 of adjacent linings are brought sufficiently close to one another.
  • FIG. 4 shows a plan view of the upper working plane 22 according to FIG. 1.
  • a respective bolt 14a, b is fastened, so that pads 24a, which fill the space between the bolts 14a and 14b, can be suspended in the bolts 14a, b.
