Definitions

  • the invention relates to an at least two-part connecting piece for holding together two of the finished wall or ceiling surface base plates of a lost formwork at a distance from one another for the production of reinforced concrete walls, sloping ceilings and the like, where appropriate, two parts of the connecting piece with foot parts each having one 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. that connector, in which according to AT-PS 380 909 the plate-shaped feet have a steep, web or the like connected heads which are designed to be interlocking like a push button. If such connectors are made of plastic, it has proven to be expedient that To effect connection with 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. Despite the excellent adhesive force of the adhesive, it is necessary to ensure that the adhesive is distributed evenly over the adhesive surfaces. If only a single connecting piece were glued in improperly, the adjacent areas of the base plate and the like will inevitably tear under a load. even in two mutually perpendicular directions. This leads to tearing or bursting of the entire plate during the subsequent loading.
  • plastic connectors mentioned above do meet the requirements, it was recognized that it is fundamentally better for security reasons to use such connectors to screw pieces with the associated base plates and, if necessary, also to manufacture them from sheet steel. In this case, it is possible to reduce the number of connectors per unit area in a cost-saving manner. Since each connector is attached to the base plate with a plurality of screws, one is completely certain to achieve the required adhesion.
  • the part (s) having the undercuts consists of a base plate with two lateral webs which have the undercuts and that the part which can be snapped into these undercuts is provided with recesses, in which recesses the undercuts of the other part can be resiliently latched.
  • the part provided with recesses is approximately X-shaped, preferably two webs each opposing and diverging extending from a common central web, the foot plates at their ends for fastening this part to one of the base plates , on the other hand, have recesses for engaging the undercuts of the other part of the connecting piece.
  • the part provided with recesses for engaging the undercuts of the other part of the connecting piece can have additional recesses for inserting additional reinforcement.
  • this is formed in three parts, etc. two symmetrically opposite parts with undercuts are provided, in which undercuts the recess conditions can be snapped onto the webs of an X-shaped or H-shaped part.
  • 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, 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 part 1 provided with undercuts 2 and the like. from a base plate 3 and two lateral webs 4 which are parallel to one another and have the undercuts 2.
  • a part 6 provided with recesses 4 can be snapped into these undercuts 2, so that the state shown in FIG. 2 results.
  • the part 6 is X-shaped in cross-section, two webs 8 and 9 each extending divergingly from a central web 7.
  • 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. provided in the manufacturing plant with parts 1 and 6, which are screwed on according to a grid.
  • Such base plates which are therefore intended for the formation of lost formwork for a wall or sloping ceiling, can be cut to the desired formats and possibly with lines, reinforcements, fittings and the like.
  • Like. Be provided. They can then be assembled and moved to form a finished formwork in the factory or on the construction site by plugging the two parts of all the connecting pieces together, whereupon the formwork is filled with poured concrete.
  • FIGS. 3 and 4 or 7 and 8 differs from that described so far only by a different embodiment of part 6, 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 are used to snap into the undercuts 2 of the associated part 1, as shown in FIG. 4.
  • FIG. 9-12 show two three-part connecting pieces according to the invention, one part 1 provided with undercuts 2 being screwed onto the base plates 11, symmetrically opposite one another.
  • the recesses 5 on the webs 14 engage either a profile with an H-shaped cross section (FIGS. 9, 10) or an X-shaped profile with a cross section (FIGS. 11, 12), the latter being provided with a central web 15 can be, from which the webs 14 extend divergingly.
  • the parts of the connecting piece according to the invention can be provided with additional recesses 15 for the insertion of reinforcements.
