Definitions

  • Such a column is disclosed in NL-A 7114828.
  • the reinforcing means used in this column are constructed as a sleeve that has a certain undersize with respect to the internal diameter of the upright. After the sleeve has been placed in the upright it is subjected to plastic deformation and expanded, such that the sleeve is firmly braced in the upright. Finally, an access opening is made in the upright and the sleeve.
  • the break is in one of the parts and the other part is opposite the break.
  • the part in which the break is located extends around the periphery over more than 180 degrees in the peripheral direction and the other part extends over the remainder of the periphery.
  • the parts can be fixed to one another in various ways, preferably by welding.
  • the invention also relates to a method for the production of a column as described above, comprising the following steps:
  • the method can be used for the production of the embodiment where the part provided with the break has at least two stops.
  • the method comprises the steps for provision of spreading means with two jaws, making the jaws engage on a respective stop via the cut-out in the hollow upright and the break coincident therewith, as well as spreading the jaws for pressing said part against the wall of the hollow upright.
  • the reinforcing means are preferably braced against the wall of the upright with pretensioning, such that the reinforcing means are able, by means of friction, to participate in the transmission of forces and moments in the column.
  • that part of the reinforcing means in which the break is located can, in particular, be braced against the wall of the upright with pretensioning.
  • the other part can also be braced against the wall of the column, but this is not actually necessary.
  • the axial dimension of the parts is preferably approximately the same.
  • the column 1 according to the invention shown in Figures 1 and 2 comprises an upright 2 as well as the reinforcing means indicated in their entirety by 3.
  • Said reinforcing means comprise two parts 4, 5.
  • the part 4 is provided with a break 6. As shown in Figure 1, this break 6 is coincident with the opening 7 in the upright 2 of the column 1.
  • the reinforcing part 4 is annular at the location of the portions 9, 10 that are below and above the opening 7, respectively. In these locations the reinforcing part 4 runs completely round the internal surface of the wall 8 of the upright 2. Such an annular portion 9 is shown in Figure 3.
  • the break 6 is somewhat less wide than the opening 7 in the upright 2, such that supporting rims for a cover 11 are formed in a known manner.
  • the part 4 extends over more than 180° around the periphery of the internal wall of the upright 2, as can be seen in Figures 2 and 3.
  • the other portion of the internal periphery of the wall 8 is filled by the part 5, as can likewise be seen in Figures 2 and 3.
  • the part 4 is braced with pretensioning against the internal surface of the wall 8 of the upright 2 by means of the tools 12.
  • stops 13, 14, on which the eccentric of the tools 12 can engage have been made on the part 4 for this purpose.
  • This eccentric 15 is joined to the lever 17 by means of a torsion rod 16. After the eccentric 15 has been placed between the stops 13, 14, spreading of the part 4 is obtained by turning the lever 12.
  • the parts 4 and 5 are then fixed to one another in this position. As shown in Figure 6, this can be obtained by means of welding equipment 18.
  • This welding equipment 18 makes welds 19, 20 between the pair of edges of the parts 4, 5 facing one another, spreading of the part 4 being maintained by means of the tools 12, as shown in Figure 5.
  • the tools 12 can be removed and the reinforcing part is firmly braced in the upright 2 with pretensioning.
  • the part 4, in which there is the opening 6, is firmly braced against the internal surface of the wall 8 of the upright 2. This portion then contributes to the transfer of forces and transfer of torque in the column 1 by means of friction.
  • the other part 5 can also be braced against the internal surface of the upright 2, but this is not actually necessary.
  • the part 5 is constructed as a slider rail with rail pieces 21 to which, for example, switching equipment for a lighting column can be fixed.
  • an alternative tool 22 is shown that is constructed as scissors.
  • the two jaws 23 of the scissors can be moved apart by operating the piston/cylinder device 24, for bracing the part 4 against the upright 2 with pretensioning.
