Definitions

  • the invention relates to a scaffold frame floor with longitudinal spars on the outside, with cross-connection parts lying on the end faces, connecting the longitudinal spars, to which suspension means are assigned, and with a walkable, liquid-permeable surface support structure that forms the tread.
  • Scaffolding is used on building walls, in industrial plants with pipes and other system parts, in other steel structures, on ship walls and the like and for many different purposes. Most of the work only produces water or dirt in small quantities. For such work in which water or dirty water is to drain off, customary scaffold floors with openings in the running and working surface are sufficient. For this purpose, the edges of the holes have been partly bent upwards and partly downwards, so that, on the one hand, a non-slip walking surface is formed and, on the other hand, the resulting liquid can flow downwards in some areas. The user then does not walk in the water. Such training is shown in DE-A-29 16 826. Wooden surfaces are desired for other purposes, such as when the user must sit on the floor, such as painting.
  • a metal stand scaffold has become known, the scaffold planks of which have a tread plate which is designed only with elongated hole cutouts for weight reduction and upstanding round cams as anti-slip protection. Letting liquids or especially dusts run off is not the basis for the design of this scaffold plank.
  • the invention has for its object to design a scaffold frame floor that can be attached to the usual scaffold support structures in such a way that it is easy to manufacture, great stability and safe use, the resulting abrasive agents from blasting treatments can pass through recesses without deposits form and the stability of the stand and use is also not impaired.
  • the thickness of the upper opening-limiting webs of the longitudinal spars and a lattice support structure forming the running surface in order to avoid storage areas for granular blasting material each have only one to four material thicknesses of the base support material sheet and the widening of the longitudinal spars required for carrying and stability reasons and possibly further supporting structure parts in the lower areas with inclined surfaces that allow drainage are extended to the widest extent of the supporting structure parts.
  • a scaffold frame floor according to the invention can be formed in a particularly advantageous manner by the longitudinal spar profile having an outer wall that forms an external vertical web, in the area of its lower end a rounded, possibly undulating, connected lower wall that forms a horizontal flange and to the inside of the Frame pointing a rounded transition corner and then has an inclined surface, which is equipped with a vertical connecting leg and the upper vertical parts are connected to the lattice-like support structure to form a load-bearing composite, preferably welded.
  • Such a profile can be easily and easily formed with high stability from sheet steel with good and inexpensive manufacturing options. With appropriate needs and usage-related conditions, it can usefully also be designed as a light metal extrusion profile.
  • a further development of the invention can provide that the upper end of the outer vertical web is equipped with an inner, inner leg serving for stability and connection by folding inwards.
  • a further development of the invention can provide that, when formed from a flat sheet, the joint is formed in the region of the inner leg with aligned end cut parts.
  • a further development of the invention can provide that the support structure is formed by vertically standing thin sheet metal parts which are brought into engagement by corresponding cutouts and that these are connected, preferably welded, to the outer frame regions.
  • a further development of the invention can provide that the surface support structure is formed by a grating.
  • a further development of the invention can provide that hanging claws made of sheet metal are fixedly arranged on the cross-connection parts.
  • the scaffold 10 has stems 11, for example with perforated disks 12.
  • U-shaped, horizontally extending crossbeams 15, which are open at the top, are fastened to them with the aid of slip-on shoes 13 and wedges 14.
  • the hooking claws 17 are fastened to cross-connection parts 21, which are provided at the two ends, in a conventional manner.
  • These cross-connection parts 21 can be designed in the form of flat irons, relatively thin, flat sheet metal parts at the top or similar to the longitudinal bars.
  • the longitudinal bars 25.1 and 25.2 have a cross section as shown in FIG. 4.
  • a sheet profile possibly a tube, is deformed in such a way that a vertical outer wall 26, a horizontal lower wall 27 and an oblique drain inner wall 28 result. These are connected to one another via rounded corners 29.1 and 29.2.
  • a wave-shaped bend 32 is formed in the area of the upper end 31 of the inclined inner wall 28 of the drain. This merges with a rounded corner 33 into a vertical inner leg 34. This is connected to the upper end 36 of the vertical outer wall 26 via a folding curve 35. Everything is shown here as if it were pressed out of a pipe. It is preferably bent, folded and folded on a roller mill from a flat sheet, for example from sheet steel.
  • the legs which are in alignment with one another can be connected by a weld seam.
  • the profile can also be made of light metal in a similar cross-sectional shape in a strand deformation process.
  • the upper fastening sections 40 are connected on the inside to the outer frame plate 41, for example by means of a continuous weld seam 42 or corresponding weld seam sections.
  • the frame plate 41 of the grating 38 is the same height or slightly higher than the dimension 44 of the fastening section 40 and protrudes slightly upwards over the fastening section 40, so that there is a good weld at 42.
  • One of two such longitudinal spars 25.1 u. 25.2 and two cross-connection parts 21 formed all around frame is filled with a conventional grating with inner, vertically arranged, matching punched out crossing support plates 45.
  • the frame sheets - as can be seen in FIG. 3 - are made of somewhat stronger steel sheet than the mesh-limiting support sheets 45.
  • the support sheets can also have a lower height in one direction or be replaced by suitably machined bars. It is important that large mesh holes are formed, which are supported by narrow-walled ribs that bear the load of the people using them, so that there are no horizontal surfaces on the scaffold floor that lead to deposits of abrasive components in the cleaning work. Also in the edge area, the support structure is so thin-walled and too knife-like at the top that no grain accumulations can remain.
  • the thickness of the upper opening-limiting webs which are formed on the one hand in the area of the longitudinal spars with the upper end 36 of the vertical outer wall 26 and the vertical inner leg 34 and the outer frame plate 41 of the grating 38 and on the other hand formed by the support plates 45 in the area of the grating support structure forming the tread are - as can be seen - only one to four material thicknesses of the base material sheet in order to avoid storage areas for granular blasting material.
  • the widening of the longitudinal spars required for load-bearing and stability reasons and possibly further supporting structure parts in the lower areas are additionally led to the widest expansion of the supporting structure parts, such as the horizontal lower wall 27, with inclined surfaces that allow drainage, such as the inclined inner wall drain 28.
  • the cross-connection parts 21 can be formed as sufficiently load-bearing, thick flat sheets. However, you can also have a profile shape that can be approximated to that of the longitudinal spars, because it is important that no horizontal surfaces are provided for deposits and that inclined surfaces lead to the horizontally wider material collections of the profiles, which allow material to flow off. Longitudinal beads or transverse embossing can also be introduced for reinforcement in relatively thin-walled metal sheets, despite the large scaffold frame floor To ensure the stability and smooth running of components of the work.
  • the hanging devices can also be adapted to the respective scaffolding system.
  • the scaffold frame floors can also be made wider or combined, depending on which scaffold structures are suitable for use.
  • a scaffold frame floor (20) has longitudinal spars (25.1, 25.2) and cross-connection parts.
  • a grating (38) is permanently installed between the fastening sections (40). This has outer frame plates (41) and inner, intersecting support plates (45).
  • the profile of the longitudinal spars (25.1, 25.2) has a vertical outer wall, a horizontal lower wall and an inclined drain inner wall (28) which merges into the vertical inner leg with a wavy bend. The grate is attached to this.
