Definitions

  • the invention relates to a support for the construction sector with at least one column part and with a plate fastened at least at one end of the column part transversely to the longitudinal axis of the column.
  • the plate and the column parts for example the outer tube and the inner tube for producing a tube support, are surface-finished, usually galvanized, for example in a manufacturing process.
  • the plate is attached to one end of the column by means of a weld seam. This can be seen, for example, from FIG. 1 of EP 0 473 894 AI.
  • the surface finish on both the column and the plate must be removed for welding so that the quality or strength of the weld seam is guaranteed.
  • the welding point usually has to be reworked and protected against corrosion.
  • the invention has for its object to produce such a support easier and therefore cheaper.
  • An advantage of the invention is that welding is no longer required to fasten the plate to the column part and therefore there is also no need to remove the surface finish in the area of the weld seam and also post-treatment as in the known supports, because the surface finish of the parts after Fastening the plate to the column part does not need to be restored.
  • the surface finishing of the column part and the plate remain intact during the production of the permanent and large force-absorbing connection of the column part and plate.
  • the support can be produced in one operation without interruption, so that cycle times for the production of the support according to the invention of approximately one minute can be achieved, which are significantly lower than the cycle times in the production of known supports, in which the plate is welded to the column part must become .
  • the stability of the support according to the invention is at least the same as when the plate is attached to the wet oil part by welding. There is also no loss of quality due to imperfect welds.
  • the projections are so long that after passing through the recesses in the plate they still protrude so far on the side of the plate facing away from the column section that after permanent deformation, e.g. Flanging and pressing, the ends of the projections with such a large area on this side of the plate with a press fit, for example up to or beyond the pinch limit.
  • the connection between the plate and the column part is rigid and so firm that it transfers all loads on the support without loosening.
  • the projections are arranged at a distance from one another, first surface sections between the projections then being provided as counter bearings, which come to rest on second surface sections between the recesses.
  • the projections can be designed as a ring and are arranged next to one another only by axial slots.
  • a central recess annular space
  • the counter bearing is formed by formations radially spaced from the column.
  • the column part of the support according to the invention can, as usual, be tubular with a circular, but also with a square or polygonal cross-section.
  • the invention can also be implemented in connection with a column part made of solid material.
  • the end of the column part facing the plate has a central recess on its end face, the outer wall of which is divided into projections, for example rags.
  • This embodiment can be further developed such that the central recess optionally surrounds a core arranged in the column axis, which in one embodiment of the invention rests with its end face as a counter bearing on the plate. This provides additional security against lateral and axial displacement of the plate in the region of the flanged ends of the projections, for example.
  • depressions for receiving the e.g. flanged ends of the projections are provided on the side of the plate facing away from the column part.
  • the plate is additionally secured against twisting relative to the end of the column part.
  • these depressions can be so deep that the ends of the projections penetrate completely into these depressions and thus do not protrude beyond the surface of the plate.
  • the plate then has a flat surface which can serve as a foot surface for the support or as a support for a ceiling formwork for concrete or the like.
  • depressions in the plate can be formed by embossing the plate, the elevations on the side of the plate facing the column part, e.g. Ribs, form. This additionally stiffens the plate.
  • the support according to the invention can be used for supports required in the construction sector, for example ceiling supports, construction supports, scaffold supports or spindle supports.
  • the projections are so long and protrude so far beyond the side of the plate facing away from the column part that, after the ends have been formed and pressed on, a rigid, non-positive connection is formed which absorbs all the loads provided for the support in question.
  • the extent to which these projections must be longer than the thickness of the plate at the recesses for the passage of the projections depends on the material and the load to be borne by the support.
  • the depressions which are provided on the side of the plate facing away from the column part and into which the ends of the projections should enter during permanent deformation, for example after flanging and during pressing, can be so large that they receive these ends almost in a form-fitting manner, or be somewhat larger, since the projections can deform somewhat plastically during forming under great pressure, so that the material of the projections then lies against the walls of the depressions.
  • the pressing pressure with which the ends are pressed into the depressions or lie against the surface of the side of the plate facing away from the column part can vary in size depending on the material from which the projections and the column part are made.
  • a pressing pressure is expedient, which deforms the ends plastically and permanently, for example up to the crushing limit or, as mentioned, also beyond.
  • the material from which the support, in particular the column part, is made can, as usual, consist of steel. However, supports made of non-ferrous metals, for example aluminum, can also be produced in the same way, the plate being made of the same material as the column part in order to avoid electrochemical corrosion / contact corrosion.
  • the axially aligned projections can be in the form of tabs, bolts, pins or the like. In one embodiment of the invention, the ends of the projections in the form of bolts or pins can be pressed broadly by means of an axial pressure such as a rivet head, so that these pin or bolt ends grip around a section of the edge boundary of the recess or the entire edge boundary of the recess in a permanently deformed manner.
  • the invention also relates to a method for producing the support described above, which consists in that when the ends of the projections are pressed onto the plate, their material is stressed to the crushing limit or else beyond.
  • the crushing limit is the limit load of a deformable material (metal), at which this material begins to flow under the pressure, i.e. is plastically deformable.
  • Such a pressing process is also referred to as "squeezing".
  • the drawing shows the parts of embodiments required for understanding the invention, in which the axially aligned projections are in the form of tabs. It shows: 1 shows the principle of the manufacture of a support according to the invention, FIGS. 1a and 1b showing the column part and the plate separately and FIG.
  • FIG. 2 shows a representation corresponding to FIG. 1 with a further embodiment of the plate, the side of which is remote from the column part is shown;
  • FIG. 3 shows the side of the plate shown in FIG. 2 facing the column part with a section of a column part
  • Fig. 4 shows a section through a column part made of solid material with a corresponding end of the column part.
  • the support shown in Fig. 1 has a column part 1, at the end of which a plate 2 extending transversely to the column axis is attached.
  • the end of the column part 1 has projections 3 which are arranged at a distance from one another and which can reach through the recesses 4 (FIG. 1 b) of the plate 2 corresponding to the width of the projections 3.
  • the projections 3 are so long that they protrude beyond the side of the plate 2 facing away from the column part 1, where they can be flanged over the edge of the recesses 4 and then pressed against the surface of the plate 2 (FIG. 1c).
  • the pressing pressure can be so great that the material of the ends 5 of the projections 3 becomes plastic and lies tightly against the surface of the plate 2.
  • First surface sections 6 between the individual projections 3 serve as counter bearings and are tight on second surface sections 7 between the recesses 4 of the plate 2, so that there is a rigid connection which absorbs all loads on the support between the plate 2 and the column part 1.
  • the column part 1 can consist of a steel tube which, in the embodiment shown in the drawing, has a circular cross section.
  • the embodiment of the invention shown in FIG. 2 differs from the embodiment according to FIG. 1 only in that the plate 8 has an approximately cruciform embossing with depressions 9 which have cavities in the surface facing away from the column part 1 and in that in the column part 1 facing surface of the plate 8 form elevations. This embossing increases the flexural strength of the plate 8.
  • FIG. 3 shows the surface of the plate 8 shown in FIG. 2 facing the column part 1 with a section of the column part 1.
  • the column part 21 consists of a solid material.
  • annular recess 22 from the outer wall of which projections 23 are formed, which protrude beyond the edge of a plurality of recesses 27 of a plate 28 and, as described and shown in FIG. 4, crimped and then to the surface of the plate 28 are pressed.
  • a core 24 designed as an axial projection.
  • the plate 28 belonging to this embodiment can be designed in accordance with the plate 2 in FIG.
  • the core 24 of the column part 21 lies over its end face on the plate 28 and forms the counter bearing.
  • the plate 28 can be designed like the plate 8 from FIG. 2 and the core 24 engages in the central opening.
