Definitions

  • the invention relates to a formwork element in the preamble of claim 1 specified Art.
  • a recessed Support shoulder shaped in the standing concrete wall For the positive connection of an in-situ concrete ceiling to one standing concrete wall, e.g. known from FR-A-2 644 823, in the connection area a recessed Support shoulder shaped in the standing concrete wall.
  • a molded from boards or polystyrene parts Formwork element in the formwork of the standing concrete wall integrated, e.g. a formwork element in box form. After filling and compacting the concrete in the formwork this formwork element is removed again to ensure that it is in perfect working order To achieve ceiling connection.
  • the making, inserting and removing the formwork element is labor intensive and expensive, especially since the formwork element in each case must be tailored. If necessary, then in the Support shoulder mounted an insulation board to prevent cracking to be built in the connection area of the cover plate. This is time consuming.
  • the invention has for its object a formwork element to create the kind mentioned above, with which universal the desired support shoulder with low working and can produce costs.
  • the lost formwork element no longer needs to be removed from the standing concrete wall to be removed. It will after connection the ceiling integrated power transmission without the connection between the ceiling and the standing wall.
  • the formwork element is easy to prefabricate in the desired size or simply at the construction site to the existing ones Adapt requirements. It comes with the spacers fixed on the reinforcement part or on reinforcement parts, e.g. by kneading or welding. Concrete is in front of and behind the shielding surface to the desired level of the support shoulder filled and compacted. Then concrete continues filled behind the shielding surface through the filling passages and condensed. The openings in the shielding surface enable a non-positive connection between the concrete and the shielding surface as well as a perfect connection the ceiling, and especially the air outlet when compressing the Concrete.
  • the openings are designed in shape and size so that the concrete is not unimpeded when filling and compacting passes.
  • the consistency unexpectedly prevents of the concrete, even when compacting, that the concrete before Shielding surface rises on the formwork or in significant Dimension passes through the openings.
  • the formwork element is stable and can be removed using the spacers set so stable that it will be among the rough ones Working conditions when filling and compacting the concrete not changed.
  • Insulation board For later crack formation in the connection area of the ceiling counteracting it is sometimes at least in the support shoulder an insulation board attached. This is expedient Insulation board according to claim 2 already attached to the formwork element, which saves time, labor and costs.
  • the embodiment according to claim 3 expediently builds on basic components known in this technology.
  • the Longitudinal and cross struts with the expanded metal are one under the trade name "Stremaform” ® (registered trademark) well-known product that in any size and format as well Basis weights are available. Leave the spacers commit themselves quickly and permanently to the Longitudinal and cross struts of the Stremaform strip.
  • the the Sheet metal plate with perforations interlocks with the Concrete, whereby the concrete cannot penetrate unhindered, to keep the support shoulder free from the specific shape and size. However, when compacting the concrete, it can contain Air are expelled, expediently the Extensive air expulsion based on the penetrations through the openings Schlempe is noticeable.
  • the embodiment according to claim 4 is useful because on the one hand fix the insulation board to the longitudinal or cross struts Holds, is easy to attach, and in addition the Openings in the shielding surface leaves open through which Air leaks when the concrete is compacted.
  • the embodiment according to claim 5 is stable and still technically simple. Structural steel bars are in different Strengths customary in the trade.
  • the brackets can be opened devices usual in this technique in the desired Bend shape and size and in usual welding equipment attach.
  • the bow shapes according to claim 6 are simple Suitable handling and allow a stable fixation of the formwork element. They leave large concrete filling passages between them free.
  • bracket according to claim 7 For permanent fastening of the formwork element in several, spaced attachment points is a horizontal one Arrangement of the bracket according to claim 7 useful.
  • the feature of claim 9 is advantageous because it is wide spaced support points on the reinforcement part of the standing Wall, and also for reinforcement parts with a coarse grid enough contact points for the brackets of the formwork element arise.
  • the spacers can also be made of flat iron be formed, which are optionally bent so that they can be attached to the reinforcement part. It is conceivable doing the spacers on site relative to the spacing area bend to fine tune the distance of the shielding surface of the reinforcement part or the depth of the support shoulder to make.
  • connection reinforcement parts are advantageous to for the connection reinforcement parts to set and connect with reinforcement parts of the standing wall to be able to.
  • the connecting reinforcement parts are in Push-through openings of the formwork element are supported.
  • each push-through opening according to claim 12 through the insulation board to the connection reinforcement parts to be able to contribute.
  • connection reinforcement parts positioned in the formwork element right from the start. This saves time when preparing the ceiling connection. It is recommended to use the push-through openings for the connecting reinforcement parts after a predetermined, the to provide grids corresponding to static requirements, or interpret this grid from the outset so that a Large range of variations for attaching the connecting reinforcement parts is made possible.
  • the embodiment according to claim 14 is particularly useful because the ascending concrete will surely rise too far is prevented.
  • the further shielding surface can, if required, with your own spacers or directly to others Reinforcement parts of the standing concrete wall set be, which results in a very stable position of the formwork element results. In practice, however, it is also sufficient that further shielding area only on the formwork element itself fasten.
  • an insulation board can also be arranged.
  • a Formwork made from formwork walls 1, 2 according to FIG. 1, which defines the later outer sides of the wall W.
  • reinforcement parts 3, 4 (only two are shown) positioned, e.g. Structural steel mats.
  • a blanket (Not shown in Fig. 1) to be able to connect Cavity 8 recessed in the finished concrete wall W according to Fig. 2 limited a support shoulder S for the ceiling connection.
  • a lost formwork element E is at least a reinforcement part 4, e.g. by rotting or welding in areas 12.
  • the lost formwork element E consists of an approximately vertical shielding surface 10 and from spacers protruding from the rear 11, which are up to or in the reinforcement part 4 extend and there - as mentioned - are fixed.
  • the spacers 11 are designed to have concrete filling passages 19 leave free, which extend from top to bottom.
  • the shielding surface 10 is provided with openings, as will be explained later.
  • concrete 5 is placed in front of and behind the shielding surface 10 filled and compressed if necessary until a level 6 is reached. After that, concrete is only 5 'by the Passages 19 filled and compressed from above. This increases the level of the concrete in front of the shielding surface 10 may be slightly on (indicated by dashed lines at 7).
  • the formwork walls 1, 2 removed.
