Definitions

  • the invention relates to a scaffold tube with a tube and at least one connection head, which has outer boundary surfaces which are designed wedge-like to a center, which has a wedge opening, which is made of cast steel, malleable cast iron or forged steel and which is welded to the center of the pipe, the tube-side end of the connection head has a suitable design for the welding of its connection area and has projecting into the tube, suitable centering auxiliary parts.
  • connection heads made of cast steel, malleable cast iron or forged steel are provided at the ends of scaffold tubes made of extruded light metal profile and are inserted into the scaffold tubes by means of suitable extensions and fastened there. Fastening openings extend through the extensions. Dome-like deformation areas of the attached and pressed-on scaffold tube are pressed into them during manufacture to secure them against twisting and pulling off. Additionally or alternatively, the respective connection head can be attached to the scaffold tube by means of welding.
  • connection head has a rear abutment end face, which is delimited on the outside by a cylindrical surface running perpendicular to it and in alignment with the outer surface of the scaffold tube, so that there is a butt seam. Because of this and because of the relatively long, thick-walled design of the extensions, there are unfavorable heat conduction conditions and therefore unfavorable automatic welding conditions.
  • connection heads are usually made of malleable cast iron and have at least three pins or centering tabs for centering in the pipe to be welded, which are matched to the inside diameter of the scaffold tube.
  • An end positioning surface projecting slightly beyond the inner diameter, which is normal to the pipe axis, is only continuous in the area of the inner diameter of the pipe.
  • the outer parts of the positioning surface are interrupted in the areas of lateral, vertically running, slightly inclined surfaces towards the scaffold tube. This means that there is no uniformly continuous seam base all around for fastening. Rather, an L-seam base is sometimes offered and an I-seam must be placed in the side areas. This and the material conditions result in irregularities with their consequences when welding all round with automatic welding machines.
  • the invention is not only suitable for the specifically known design, but also for other, similar connection heads with associated elements, in which similar problems arise.
  • connection heads are attached to the elongated scaffolding elements by welding.
  • an approach is provided according to the drawing, which is adapted to the free end of the horizontal bar and is expediently fastened by means of a weld seam.
  • a continuous conical surface without special alignment aids is provided for insertion, centering and fastening, which leads to welding with V-seam or L-seam.
  • the exact alignment to the pipe during welding requires appropriately aligning aids, since there is no abutment surface or abutment ring surface.
  • connection head for a cup-like connection which has a centering insert with a rounded end for engaging in the end of the elongated scaffold element, which is inserted into the pipe end.
  • the inner edge of the pipe end is based on the rounded transition between the connection head and the spigot in a less precisely defined form.
  • a chamfer on the tube allows a V-seam to be attached.
  • the invention has for its object to improve the design of the connection of the connection head with the scaffolding tube so that, given the dimensions of such connection heads specified by the modular system, more favorable automatic welding conditions result with good centering and alignment conditions.
  • connection head in its parts projecting beyond the diameter of the scaffold tube, can be bounded on the back by a spherical partial surface adjoining the cylindrical part in the connection area.
  • the scaffold 10 according to FIG. 1 has stems 11 and scaffold floors 12 which are suspended in horizontally lying support bars 14 with the aid of hooking claws.
  • the stems 11 are supported on height-adjustable feet 15 on the floor.
  • Connection elements in the form of perforated disks 17 are fastened on the stems 11 at a distance 16 corresponding to the scaffolding basic grid measurement system.
  • Such perforated disks 17 can be equipped with the illustrated, but also with differently shaped holes and additional auxiliary devices.
  • holes 29 of different sizes are formed in a known manner; namely for the scaffold elements 20 to be connected at right angles to one another, such as, for. B. the horizontal bars 18 and the support bars 14, the smaller holes 29.1 and for diagonally connected scaffolding elements 20, such as. B. the diagonal bars 19, the larger holes 29.2.
  • the scaffolding elements 20 are primarily horizontal bars 18 and diagonal bars 19. These can have different lengths depending on their intended use. Horizontal bars 18 can also be used as a railing - as shown above in Fig. 1.
  • the scaffold elements 20 are formed with cylindrical scaffold tubes 21, to which the connection heads 25 are welded.
  • Known wedges 26 are guided and secured by appropriate wedge openings. They have a protruding pin or rivet 27 in the lower end area to prevent loss.
  • a lateral recess 28 is designed in such a way that the wedge 26 can be placed parallel to the scaffold tube 21 in the raised position.
  • connection head 25 has a connecting region 30, a perforated disk slot 31 and contact surfaces 32, by means of which it is supported on the stem 11 when it is inserted with the perforated disk slot 31 via a perforated disk 17 in a known manner. It has wedge openings 33.1 and 33.2 lying vertically one above the other through which the wedge 26 is guided.
  • the upper wedge opening 33.1 is designed in the edge region with an inwardly projecting stop bead 34 for the engagement of the rivet 27 which serves to prevent loss. It is open in the rear pivot area 33.3 in a known manner, so that the wedge 26 can be pivoted backwards when the heads of the rivet 27 are supported on the opposite stop beads 34.
  • the wedge openings 33.1 and 33.2 are so wide that the heads of the rivet 27 can be carried out comfortably.
  • the perforated disk slot 31 has rounded insertion corners 36, which are also designed in a known manner.
  • connection head 25 is - seen in plan view (Fig. 4) - tapered inwards towards the stem and disc center 37, the outer boundary surfaces 38.1 and 38.2 being even in the edge contours of their outwardly projecting beads, as is also the case was common with previous connection heads. This is done so that you can also connect diagonal bars and whose connection heads can be placed as closely as possible on the outer boundary surfaces of the connection heads of rods which are at right angles to one another.
  • the outer boundary surfaces 38.1 and 38.2 have recesses 39.1 and 39.2 between their beads to save weight, which are also essentially designed in a known manner.
  • the rear end surface 40 of the solid material areas of the front connection head part is, in deviation from the previous type, not designed as a plane, but rather as an outwardly inclined surface, as shown in FIGS. 2 and 5. It is advisable to choose the shape of a partial sphere. It is thereby achieved that, with the stability of the entire connection head 25 unchanged, the welding devices to be guided around the connection area can be guided more freely and can be designed more appropriately in order to achieve improved welding in the connection area 30.
  • These end surface parts of the end surface 40 which are designed as partial spherical surfaces, rise from partial cylinder surfaces 45 which have approximately the outer diameter 41 of the tube 21.
  • the upper partial cylinder surface 45 is only slightly cut in the middle in the middle of the rear swivel area 33.3 of the upper wedge opening 33.1.
  • the upper and the lower partial cylinder surfaces merge into inclined surfaces 47.1 and 47.2 in the vertical edge regions which directly adjoin the outer boundary surfaces 38.1 and 38.2, as clearly shown in FIG. 5 in particular. These inclined surfaces 47.1 and 47.2 extend approximately to the groove base 49 of the weld seam 50.
  • the groove base 49 is delimited by an abutment ring surface 51 which extends over the entire welding area.
  • the abutment ring surface 51 has a circle as the inner boundary, which is approximately as large as the inner diameter 53 of the scaffold tube 21. Its outer diameter 54 is selected so that there is a favorable V-seam welding. It adjoins the abutment ring surface 51 with a conical surface 55 which widens towards the front and, together with the end surface 56 of the scaffold tube 21 which has just been cut off, limits the half V-seam for welding, this conical surface 55 only having a very slight kink in the side Sloping surfaces 47.1 and 47.2 merges practically continuously, so that there are no interruptions in the material flow during the continuous introduction of the weld seam.
  • the combination of these design features ensures that, on the one hand, for interchangeability in the modular system, the dimensions of such connection heads which have been customary up to now are observed, and on the other hand, better welding can nevertheless be achieved.
  • inwardly projecting centering tabs 60 are provided which fit into the scaffold tube 21, the outer limits of which correspond to the inside diameter 53 of the scaffold tube 21 and which, moreover, are bevelled and pass into the inner opening 61. They have a width that can be a little less than 1/8 of the circumference. Her size depends on the design options and the acceptable weight, taking into account that they are sufficiently stable during assembly and welding and do not hinder. They have been designed in a similar way up to now.
  • connection area 30 with the abutment ring surface 51 and with the adjacent cone surface 55 and inclusion of the other sensible surface designs result in significantly improved welding conditions which significantly promote the safety of the connection for the components and thus significantly contribute to the overall safety of the scaffolding contribute.
  • the same connection heads can be used with the appropriate devices on a short piece of scaffolding tube for connecting diagonal bars and can also be used for other auxiliary devices by designing the scaffolding tube piece accordingly.
  • connection head (25) for scaffolding with connection devices has a connection area (30) which has centering tabs (60) and has an abutment ring surface (51) and a cone surface (55) to create favorable welding conditions.
