Definitions

  • the invention relates to a tragf 'ähige, bendable St tzfolie with shock or OVERFLOW appungszonen and arranged regularly in the longitudinal and transverse directions ässig in distance ein ⁇ each other by shaped bottom wells that tight packaging for receiving a closing f1 i edible, self-curing mass are suitable, the supporting film resting with the recesses on an essentially flat base forming vault-like cavities.
  • the invention further relates to the use of the support film as a formwork for the production of in-situ hardening floors.
  • a film stiffened by forming depressions which as a moisture and vapor barrier, possibly also sound and heat insulating component in high, low, water and road construction is usable.
  • the pyramid-shaped depressions form contiguous hexagons. As a result of the hexagonal arrangement, the depressions which are directly adjacent to one another should almost equalize the bending strength in all directions.
  • the side surfaces of the walls are convexly curved and their bottoms are preferably thicker than the side walls.
  • DE-OS 31 03 632 describes a hollow floor with an upper floor resting on supporting feet on a sub-floor and forming a cavity with this.
  • the support feet are designed in the form of circular knobs which, when filled with the material of the top floor, form molded parts with a smooth coating. The support feet are molded onto the top floor and form a vault-like structure without flat side surfaces.
  • the circumferential walls of the support feet meet the sub-floor essentially perpendicularly.
  • the circumferential walls of the support feet continuously widening upwards, merge into the horizontal top floor without kinks.
  • the underbody supporting the supporting feet has a smooth coating.
  • the inventors have set themselves the task of creating a load-bearing, bendable supporting film with depressions which are shaped downwards on one side and are suitable for receiving a flowable mass which cures on the spot and which is used in particular as a formwork formwork Production of top floors hardening therein is used, has a high load-bearing capacity and is simple and inexpensive to manufacture.
  • reinforcing beads formed at least over the area of the four side edges of the upper truncated pyramid and the corners of the kink, which begin in the edge and in the flat area of the four side edges of the lower truncated pyramid run out.
  • the reinforcing beads which extend along the side edges of the upper truncated pyramid over the kink, play an essential role in that they both significantly increase the load-bearing capacity and - in cooperation with the kink - effectively counteract torsional forces In terms of effectiveness, it has proven to be particularly advantageous to narrow the cross section of the reinforcing beads downwards. For technical reasons, trapezoidal and semicircular cross sections are particularly suitable.
  • the transition of the reinforcing bead into the flat area of the side edges of the lower truncated pyramid is particularly delicate. This transition is therefore preferably not made via a kink, but the underside of the reinforcing bead merges tangentially into this areal area in a curved form.
  • the reinforcing beads are preferably 5-20 mm wide and deep, preferably 10-15 mm.
  • the support film 0.3-1 mm thick It has proven to be expedient to make the support film 0.3-1 mm thick. On the one hand, this must not be too thin in order not to reduce the load-bearing capacity to an extent that is no longer acceptable. On the other hand, however, it must not be so thick that, with the material used accordingly, the heat transfer is insulated too much and the production is too expensive.
  • the angle (s) of inclination of the side faces of the upper truncated pyramid with respect to the horizontal is preferably between 10 and 60 "(old division), in particular at 15-30 °.
  • a small angle has the advantage "On the one hand, little material is needed to fill the support film, and on the other hand, a voluminous cavity can form below the support feet.
  • the lower limit for the angle (s) of inclination is the resilience of the top floor, which is also outside the area the contact surface of the support feet must be secured.
  • a relatively steep angle of inclination or the side faces of the upper truncated pyramid results in high material consumption, reduces the cavities, but on the other hand ensures a regularly distributed high load capacity of the
  • the optimal angle of inclination ⁇ is determined from the requirements placed on the top floor st that four identical inclination angles are formed in the case of a square horizontal cross section, whereas in the case of a rectangular cross section two opposing inclination angles are the same. The more the aspect ratio of sides of the rectangle deviates from 1, the more different are the two inclination angles o> which are not opposite one another.
  • the angle of inclination ⁇ of the side surfaces of the lower truncated pyramid is always greater than the angle of inclination n.
  • the angle of inclination ⁇ is / are preferably in the range of 30-80 °, in particular 60-75 * .
  • various aspects have to be taken into account in order to optimize the angle of inclination ⁇ , for example the consumption of filler material and the load-bearing capacity and, in the case of top floors made with the film, the potential danger of jamming installation cables in the cavity formed below the support elements .
  • the support film preferably consists of a thermoplastic, in particular of polyvinyl chloride (PVC), polyolefins, such as polyethylene (PE) or polypropylene (PP), or polyaromatics, such as polystyrene (PS).
  • PVC polyvinyl chloride
  • PE polyethylene
  • PP polypropylene
  • PS polyaromatics
  • Support foils made of thermoplastic are manufactured using the usual lace processes.
  • the support foils can, however, also consist of a metal that is easy to deep-draw, for example aluminum or aluminum alloys. Metal foils do not have to be removed after the top floor has hardened because they are thermally highly conductive.
  • insulation can be provided in the lowest region of the lower truncated pyramid. This can be done in a known manner by inserting appropriately shaped, heat-insulating platelets, for example made of cork or an organic or ceramic rigid foam. However, the bottom area of the lower truncated pyramid is covered more easily and cheaply with a portion of heat-insulating powder or porous granules.
  • the thermal insulation can be introduced before or after the installation of the support films on the construction site.
  • the support foils are preferably produced and stored in the form of plates, but in the form of rolls.
  • the outermost recesses can be placed one inside the other for simplified assembly.
  • the edge area can have means for connecting film webs or plates.
  • those known from the packaging industry Flares are used, which only need to be put together and pressed together. Instead of pressing together, however, a self-curing adhesive or a thermal lacquer can also be used. Instead of exchanges, however, it is also possible to form grooves which can be changed and which in turn can be easily glued or tightly connected by thermal treatment.
  • the support film has a wide range of uses in the field of civil engineering, it is primarily used as a formwork for the production of in-situ curing top floors.
  • the support film with its depressions or the support feet is placed on the cleaned, untreated floor or provided with a protective layer, the transition points between the plates or sheets of the support film are sealed, if necessary, and a flowable mass is poured in. If the flowable mass consists of a suspension, it is self-leveling, takes up a horizontal position and forms a smooth surface. If the flowable mass is of greater consistency, it must be smoothed out. Concrete, for example, has been found to be flowable masses or screed that has good load-bearing capacity with high heat conduction.
  • FIG. 2 shows a vertical line through a support film according to FIG. 1, with a lower one of different lengths
  • FIG. 3 shows a section of a support film with four wells spaced from each other.
  • the recess 10 of a support film shown in FIG. 1 is square in cross section.
  • a surrounding edge 12 lies in the plane of the film.
  • a horizontally circumferential bend 14 separates the depression into two truncated pyramids, the side surfaces 16 of the upper truncated pyramid 18 being flatter than the side surfaces 20 of the lower truncated pyramid 22.
  • reinforcing beads 24 are formed in the region of the side edges of the upper truncated pyramid 18, which have a trapezoidal cross-sectional shape tapering downwards.
  • the reinforcing beads 24 begin in the edge region 12 and end in the flat region of the four side edges 26 of the lower truncated pyramid 22.
  • the bottom surface 28 of the depression 10 is octagonal in the present case.
  • indentations 10 with different high lower truncated pyramids 22 are indicated, but only the lowest area of the indentation, which serves as a supporting foot in the finished hollow floor, is shown.
  • the inclination of the side surfaces can be seen particularly well from this figure.
  • the side surfaces 16 of the upper truncated pyramid 18 have the angle of inclination,, which is significantly smaller than the angle of inclination ⁇ of the side surfaces 20 of the respective lower truncated pyramids 22.
  • FIG. 3 shows how four adjacent depressions 10 of a support film are formed.
  • the width of a film web can e.g. four to twenty indentations, depending on the dimensions of indentations and film web.
