Definitions

  • the invention relates to a scaffold tube with a tube and at least one connection head, the outer boundary surfaces which is wedge-like on a center are designed to converge, the one wedge opening has that of cast steel, malleable cast iron or forged Steel exists and is welded to the center of the pipe is, the pipe end of the Connection head one suitable for welding Has formation of its connection area and suitable centering auxiliary parts protruding into the pipe has and an abutment ring surface (51) for the tube (21) is formed on the connection head (25).
  • connection heads are usually made from malleable cast iron and have to be welded for centering Tube at least three pins or centering tabs, which are matched to the inside diameter of the scaffold tube are.
  • the outer parts of the positioning surface are in the areas of lateral, vertical, slightly inclined towards the back of the scaffold tube Interrupted areas. So comes for attachment not an evenly continuous all around Seam bottom. Rather, it sometimes becomes an L-seam base offered and must in the side areas a 1-seam can be made. Because of this and through the material conditions result from all-round welding with welding machines irregularities with its consequences.
  • the invention is not only for the specifically known Design suitable, but also for others, similar Terminal heads with associated elements where similar problems arise.
  • connection head known for a cup-like connection, which for the Engagement in the end of the elongated scaffolding element a centering insert with rounded end formation has, which is inserted into the pipe end. there puts the inner edge of the pipe end on the rounded Transition between connection head and spigot in a little precisely defined form.
  • a chamfer on the pipe allows the application of a V-seam.
  • the invention has for its object the design the connection of the connection head with the scaffold tube to improve so that in compliance with the the modular system given dimensions of such Connection heads, with good centering and alignment conditions more favorable automatic welding conditions surrender.
  • connection head according to claim 4 in its about Parts of the scaffold tube protruding on the back of one on the cylindrical part in Connection area adjoining spherical surface be limited. So is that for the one resulting from the stress Force flow required amount of material arranged favorable places and there are sufficient Free space for all-round welding without interference the stability of the connection head with less Material expenditure and favorable space conditions achieved for the welding machine parts.
  • the stem 1 has stems 11 and scaffold floors 12, with the help of hanging claws in horizontal horizontal support bars 14 are suspended.
  • the stems 11 are based on height-adjustable feet 15 on the floor from.
  • connection elements in Form of perforated discs 17 attached to the stems 11.
  • Such perforated disks 17 can be but also with differently shaped holes and additional ones Auxiliary equipment.
  • With this preferred embodiment are different large holes 29 formed in a known manner; and for those to be connected to each other at right angles Scaffold elements 20, such as. 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 vary depending on have different lengths for their intended use. Horizontal bars 18 can also - as shown above in Fig. 1 - be used as a railing.
  • the scaffolding elements are 20 with cylindrical scaffold tubes 21 which the connection heads 25 are welded, formed.
  • Appropriate wedge openings are known per se Wedges 26 guided and struck. They have one in the lower end area to protect against loss by protruding pin or rivet 27.
  • a side recess 28 is designed so that the wedge 26 in the Place the raised position parallel to the scaffold tube 21 can.
  • connection head 25 has a connection area 30, a perforated disc slot 31 and contact surfaces 32, by means of which it is supported on the handle 11, if he over with the perforated disc slot 31 a perforated disc 17 is inserted in a known manner. It has wedge openings vertically one above the other 33.1 and 33.2 through which the wedge 26 is guided.
  • the upper Wedge opening 33.1 is in the edge area with a inside protruding bead 34 for the installation of the designed to protect against loss of rivets 27. she is in the rear swivel range 33.3 in a known manner open so that you can swing the wedge 26 backwards can, if the heads of the rivet 27 on the opposite Support stop beads 34.
  • the wedge openings 33.1 and 33.2 are like this wide that the heads of the rivet 27 carried comfortably can be.
  • Perforated disc slot 31 rounded insertion corners 36 which are also designed in a known manner.
  • connection head 25 is - in plan view (Fig. 4) seen - wedge-like inwards on the stem and Disc center 37 designed tapered, the outer boundary surfaces 38.1 and 38.2 in the marginal contours their bulges projecting outwards are, as is also common with previous connection heads This is done so that you can also run diagonally Connect rods and their connection heads as close as possible to the outer boundary surfaces of the Connection heads of bars at right angles to each other can put on.
  • the outer boundary surfaces 38.1 and 38.2 have to save weight between their Bumped wells 39.1 and 39.2, which are also are designed essentially in a known manner.
  • the rear end surface 40 of the massive Material areas of the front connection headboard is in deviation from the previous type not as a level, but designed as an outward sloping surface, like 2 and 5 show it.
  • Elevate end surface parts of end surface 40 consist of partial cylinder surfaces 45, which are approximately the outer diameter 41 of the tube 21 have.
  • the top cylinder face 45 is only in the upper area in the middle quite a bit of the rear swivel range 33.3 upper wedge opening 33.1 cut.
  • top and the lower cylinder surface go in the vertical Border areas that are directly adjacent to the outer boundary surfaces Connect 38.1 and 38.2, in inclined surfaces 47.1 and 47.2 via - as is particularly the case in FIG. 5 - clearly shows. These sloping surfaces 47.1 and 47.2 are sufficient approximately up to the groove bottom 49 of the weld seam 50.
  • the groove base 49 is one over the whole Annealing surface 51 passing through the welding area limited.
  • the abutment ring surface 51 has an inner boundary a circle about the size of the inside diameter 53 of the scaffold tube 21. Your outer diameter 54 is chosen so that a cheap V-seam welding results. It joins the Bump ring surface 51 an expanding forward Cone surface 55, which together with the just cut End surface 56 of the scaffold tube 21 half V-seam limited for welding, this Cone surface 55 with only a very slight kink in the lateral inclined surfaces 47.1 and 47.2 practically continuously passes over so that there are no interruptions the material flow during continuous insertion the weld seam result.
  • the outer limit of the inner diameter 53 corresponds to the scaffold tube 21 and the in the remaining bevelled pass into the inner opening 61. They have a width that is slightly less than 1/8 of the Extent can be. Your size depends on the design options and the justifiable Weight, taking into account that they are Assembly and welding are sufficiently stable and not hinder. You are already similar in a similar way have been designed so far.
  • connection area 30 Due to the advantageous, new design of the connection area 30 with the abutment ring surface 51 and with the adjacent cone surface 55 and inclusion of the other sensible surface designs significantly improved welding conditions, which is essential to the security of the connection for the components promote and thus to the overall safety of the scaffolding contribute significantly.
  • Same connection heads can with the appropriate facilities at one short piece of scaffold tube also for connecting diagonal rods are used and also for other auxiliary facilities be used by the scaffold tube is designed accordingly.
  • connection head (25) for scaffolding with connecting devices has a connecting area (30) which has centering tabs (60) and has an abutting ring surface (51) and a conical surface (55) to create favorable welding conditions.
