Definitions

  • the invention relates to a device for bracing formwork parts on a formwork jig or on construction sections that are to be manufactured or that have already been manufactured.
  • the formwork parts To erect buildings, in particular when manufacturing concrete walls, the formwork parts have to be pressed against a formwork jig or, in the case of section-by-section manufacture of construction sections, against existing construction sections.
  • this is handled in particular in the case of round buildings in such a way that clamping wedges are driven in at appropriate intervals, so that the formwork parts are prestressed accordingly in the horizontal direction so that they are then pressed onto the formwork jig or the finished construction section.
  • G lun especially in the manufacture of round or circular structures often difficulties arise because the friction between the mold parts and existing construction phases is very large, so that a proper tension is almost impossible. Difficulties arise in particular when using wooden formwork parts.
  • the invention has for its object to provide a device for bracing formwork parts with which these disadvantages can be remedied and with which a perfect bracing is made possible.
  • This device according to the invention is characterized by a hose which can be inserted pneumatically or hydraulically between the outer surface facing away from the formwork surface of the formwork parts and a fixed abutment.
  • FIG. 1 shows a vertical section through a formwork which is attached to an already existing construction phase
  • Fig. 2 shows an embodiment of the device according to the invention enlarged
  • Figure 3 shows a partial section of the device in a circular formwork
  • 4 also shows a partial section of the device in plan view; where the formwork is attached to an existing construction phase.
  • the formwork parts 1 and 2 which can be designed as formwork panels or individual boards, must be pressed against a corresponding formwork gauge, which results in the distance between the two formwork parts 1 and 2, or against construction sections 3 that are to be produced or have already been produced.
  • the lower edge of these formwork parts 1 and 2 must therefore be pressed against the finished construction section 3 in the embodiment according to FIG. 1, so that the next construction section can be concreted.
  • formwork systems can be used here, several formwork parts 1 and 2 being held together by longitudinal beams 4.
  • a pneumatically or hydraulically inflatable hose 5 is now provided, which bze between the outer surface 6 of the formwork parts. 2 and a fixed abutment in the form of a profile rail 7 is inserted.
  • a profile rail 7 is expediently provided here, which is designed to be open on the longitudinal side facing the formwork parts 1, 2. Furthermore, this profile rail 7 is designed to be as rigid as possible in order to be able to absorb a corresponding pressure acting perpendicular to the formwork parts 1 and 2.
  • the most expedient embodiment for the profile rail 7 is a U-shaped cross section, as can be seen in particular from FIG. 2. The one in the profile rail?
  • the hose 5 used then expediently has a rectangular cross section, so that when the pressure medium is introduced, this hose 5 can only expand to one side, namely to the open profile side.
  • a hose with a circular cross section could also be used, but then much more pressure medium is required to achieve a corresponding contact pressure, because the entire space within the profile rail 7 must also still be filled.
  • an embodiment would also be conceivable. in which the profile rail? has an approximately C-shaped cross section.
  • the embodiment according to the invention is particularly suitable for the production of arched, in particular circular, structures.
  • the profile rail 7 can then be arranged near the outer surface 6 of the formwork parts 1, 2, said circumferentially closed profile rail 7 being single Lich must be hung on the formwork parts 1 and 2.
  • corresponding hooks 8 can be provided on the formwork parts 1 and 2, in which the profiled rail 7 is suspended via connecting rods 9. No struts towards the center are required here, since this profile rail 7 is only subjected to pressure, especially since the same load occurs on the profile rail 7 when it is circumferentially closed. As a result, there are no bending forces.
  • the device according to the invention can therefore be used in particular in the case of round buildings without any particular design effort.
  • the profile rail 7 is of course then subjected to tension, so that here, too, no additional supports or struts are required.
  • the profile rail 7 can be disassembled for transport, it consists of individual profile pieces 7 'which can be connected to one another via flanges 10.
  • the hose 5 only has to be connected to a corresponding pump so that the pressure medium can be supplied to the hose 5 after the formwork parts 1 and 2 have been moved.
  • the tube 5 can be inflated by compressed air or an appropriate liquid. Since the hose 5 is covered on the outside by the profile rail, it cannot be damaged by rough construction site operation, since it remains in this protected position even when the formwork is moved on to the next construction phase.
  • the construction of the first construction phase can also be carried out without a formwork gauge.
  • the formwork is made according to the desired building shape set up and the space is then filled with concrete.
  • the contact pressure to the formwork ie the pressure in the hose 5 is increased so that the position of the formwork parts cannot change.
  • the abutment which can also be designed there in the form of a profile rail, must be provided with corresponding struts so that a uniform contact pressure is ensured.
  • a fixed sales opportunity for the abutment must be created.
  • it can be supported on an opposite wall or the two abutments of the inner and outer formwork are connected to each other by tension struts.
  • a connection can also be made by anchors embedded in the concrete, so that a sufficient pressure can be built up in the hose between the abutment and the formwork.
  • the most advantageous is the use of the device according to the invention in round buildings, for example in the manufacture of silos, round stables, liquid manure pits, digesters, etc.
  • the abutment can of course also be formed in a different way than by a profile rail.
  • a corresponding receiving groove for the hose 5 could also be attached to a corresponding working platform, which is pulled up with the formwork in each case.
  • This device can be used both in the first construction phase and when starting on construction phases that have already been manufactured. A perfect pressing is guaranteed, especially at the transition between two construction phases, so that there is always a smooth transition.
