Definitions

  • the invention relates to an at least two-part connector for holding together the finished wall or ceiling base plates of a lost formwork at a distance from each other for the production of reinforced concrete walls, sloping ceilings, etc., where appropriate, with two parts of the connector with foot parts each one of the base plates non-positively, e.g. by screwing, are connectable and at least one of the parts has undercuts into which the other part can be snapped.
  • Connectors of this type are known and are widely used, e.g. the connecting piece in which, according to AT-PS 380 909, the plate-shaped feet have heads connected via a stem, web or the like, which are designed to be interlocking like a push button. If such connectors are made of plastic, it has proven to be expedient to effect the connection to the base plates by gluing, since adhesives according to the current standard have a sufficient adhesive force, which often exceeds the cohesive force of the material, for example a chipboard .
  • a disadvantage here is the relatively long setting time of the adhesive, which is why the plates provided with the connecting pieces have to be temporarily stored in large storage rooms until they can be used.
  • the part (s) having the undercut is / are U-shaped and consists of a base plate with two lateral webs which have the undercuts exists (exist), which extend perpendicular to the footplate, and that the part which can be snapped into these undercuts is provided with spreadable, provided with recesses, into which recesses the undercuts of the other part can be resiliently latched crosswise.
  • the part B provided with recesses is approximately X-shaped, with two webs extending opposite and diverging, preferably from a common central web, which at one end have foot plates for fastening this part one of the base plates, on the other hand have recesses for engaging the undercuts of the other part A of the connecting piece.
  • Part B (the part provided with recesses for engaging the undercuts of the other part of the connecting piece) can advantageously have additional recesses for inserting additional reinforcement.
  • this is formed in three parts, etc. two symmetrically opposite, undercut parts A are provided, into which undercuts the recesses on the webs of a cross-sectionally X-shaped or H-shaped part can be snapped.
  • the connector according to the invention makes it possible, as in the method mentioned at the beginning, described in AT-PS 380 909, to produce a lost formwork for a wall or sloping ceiling in two parts in order to store it easily, cut it to the desired format, transport it and only then to be able to merge at a later time.
  • cutouts and openings can be provided for a sloping wall or ceiling, cables and additional reinforcements can be inserted, regardless of the actual setting process of the formwork on the construction site.
  • FIGS. 1 and 2 show a first exemplary embodiment before and after the two parts have been joined together.
  • 3 and 4 a second embodiment, also before and after assembly.
  • 5 and 6 a connecting piece according to FIGS. 1 and 2 is shown in the state attached to two base plates.
  • 7 and 8 show, analogously, the second exemplary embodiment according to FIGS. 3 and 4.
  • FIGS. 9 and 10 or 11 and 12 illustrate a further connecting piece consisting of three parts, each in two views, also fastened to two base plates, that they distance and hold together.
  • the connecting piece according to FIGS. 1 and 2 consists of a U-shaped part A and the like provided with undercuts 2. from a base plate 3 and two lateral webs 4 parallel to one another and having the undercuts 2.
  • a part B provided with recesses 5 can be snapped into these undercuts 2, so that the state shown in FIG. 2 results.
  • Part B is X-shaped in cross section, whereby I extend two webs 8 and 9 divergingly away from a central web 7.
  • the webs 8 can be spread apart in order to make it possible for the webs 4 provided with undercuts to not snap into place crosswise.
  • the webs 9 end in angled base plates 10, which have the bores required for screwing this part onto a base plate 11, as can be seen in FIGS. 5 and 6.
  • the base plates 11 can be e.g. Provide parts A and B in the manufacturing plant, which are screwed on according to a grid.
  • Such base plates which are therefore intended for the formation of a lost formwork for a wall or sloping ceiling, can be cut to the desired formats and possibly with lines, reinforcements, fittings and. Like. Be provided. Then they can be assembled and moved to a finished formwork already in the factory or on the construction site by plugging the two parts of all connecting pieces together, whereupon the formwork is filled with flow concrete.
  • FIGS. 3 and 4 or 7 and 8 differs from that described so far only by a different embodiment of part B, which in this case has a U-shaped profile.
  • a base plate 12 is provided with lateral webs 13 which have recesses 5. These recesses 5 serve to snap into the undercuts 2 of the respectively associated part A, as shown in FIG. 4.
  • FIG. 9-12 show two three-part connecting pieces according to the invention, wherein on the base plates 11, opposite each other symmetrically, a part A provided with undercuts 2 is screwed.
  • the recesses 5 on the webs 14 engage either a cross-sectionally H-shaped (FIGS. 9, 10) or a cross-sectionally X-shaped profile (FIGS. 11, 12), the latter being provided with a central web 15 can be, from which the webs 14 extend divergingly.
  • the parts B of the connecting piece according to the invention can be provided with additional recesses 16 for the insertion of reinforcements.
