Definitions

  • the present invention relates to a support film according to the preamble of claim 1.
  • support foils are used, which in themselves consist of a flexible, attached to the sub-floor matching material, preferably a thermoplastic plastic is used.
  • These support foils which are primarily geometrically square or rectangular in shape and are available in bulk with a side length in the order of magnitude of approx. 1 m, have this foremost to ensure a reasonable palletization for transport, usually produced using deep-drawing processes, downward-shaped and tightly closing recesses, which, supported on an underbody, take on the function of support feet.
  • the flexibility of the support film is kept flexible or bendable, so that it can adapt to any unevenness in the sub-floor.
  • the support feet which are used at regular intervals in the longitudinal and transverse directions, create a uniform support structure and load distribution. Since the final purpose of these cavity floors, among other things, also serves to lay cables and pipes in an advantageous manner, it must be consequently ensured that the Alignment of the depressions in the x- and y-axis of a surface composed of many supporting foils remains a uniform one, ie the regular arrangement of the depressions in a single supporting foil must be maintained when all the supporting foils are bonded.
  • One solution for realizing this postulate is to design the laying so that the transitions of two adjacent supporting foils come together as a bond through these depressions, in such a way that the depressions of the additional supporting foil serve as patrices to the depressions of the pre-laid supporting foil.
  • this method has the advantage that the alignment of the recesses with one another remains a uniform, regular one over the entire composite of all laid support foils;
  • this type of solution has the major disadvantage that there is a relatively large overlap between two adjacent support foils, which results in up to 20% material loss, i.e. in other words, the gross supporting surface required to lay a certain area on a cavity floor must be over 20% larger.
  • the invention seeks to remedy this.
  • the object of the invention is to remedy the aforementioned disadvantages in the case of a support film of the type mentioned at the outset.
  • the main advantage of the invention can be seen in the fact that the butting or overlapping zones of the support foils, which are present anyway for manufacturing and strength reasons, are expanded by means which enable the support foils to interlock with one another, always according to that for laying the Support film is an indispensable prerequisite, according to which the alignment of the depressions is maintained, with which a maximized saving of the support film area can be achieved.
  • Another important advantage of the invention is the fact hen to se ⁇ that the funds allow for easy installation of individual supporting films in a composite: This installation ge staltet just as simple as the "be ⁇ the prior art, signed, in which the individual recesses take on the function of a male and female.
  • FIG. 5 shows the design of the connecting means according to FIG. 4;
  • the individual support foils are congruent with regard to the outer dimensions and the inner configuration, so that they can be stacked and palletized for transport purposes.
  • the stackability is achieved in that the individual depressions 3 serving as support feet alternately assume the function of male and female molds.
  • the ability to palletize is a function of the outer dimensions of the support foils, which, preferably, are to be aligned with the international pallet standards. However, this is not an essential requirement.
  • the physical shape of the depressions 3 is discussed in more detail below.
  • the support films 1 and 2 have butt or overlap zones la, lb and.
  • connection between the individual support foils 1, 2 should, if possible, be created by means 4, 5 which do not require a positive connection.
  • very structurally unstable supporting foils that is to say foils with a minimal material thickness
  • one will not be able to avoid providing means which are connected by a frictional connection by means of friction or mechanical locking, for example by means of a push button-like structure.
  • a non-releasable connection between the individual support foils can also be provided.
  • FIG. 2 is a view along the sectional plane II-II in FIG. 1.
  • the overlap of the two support foils 1, 2 and the connection 6 resulting from the interlocking of the two connecting means 4, 5 are clearly visible, here the bulge 4 fulfills the function of a matrix in the joint or overlap zone la, while the other bulge 5 in the joint and overlap zone 2a takes over the function of a male.
  • the depressions 3 serving as support feet have the shape of a truncated cone, the cone angle depending on the support film configuration in question, ie on the services to be performed.
  • the side surfaces of the supporting foot 3 shown can run at a fixed angle, which is also valid for other supporting feet, they can also create the shape of the supporting feet at a progressive or degressive angle.
  • connection 6 created via the bulges 4 and 5.
  • These bulges 4, 5 can easily be frustoconical, truncated pyramid-shaped with a square or rectangular cross-section, or the shape of the support feet 3 can be designed.
  • the connection 6 shown here is inherently a detachable connection without frictional connection. Such a connection does not become detachable if, for example, an adhesive process is provided in the area of the connecting means 4, 5 and / or the intermediate spaces on the butt or overlap zones 1 a, 1 b, 2 a, 2 b.
  • the support film preferably consists of a thermoplastic, in particular ' of polyvinyl chloride (PVC), polyolefins such as polyethylene (PE) or polypropylene (PP), or polyanomatics such as polystyrene (PS).
  • PVC polyvinyl chloride
  • PE polyethylene
  • PP polypropylene
  • PS polyanomatics
  • Support foils made of thermoplastic are produced by conventional spraying processes.
  • the support foils can also consist of a metal that can be deeply drawn, 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 anyway.
  • the support foils in the form of plates are preferred, as the exemplary embodiments show; they can, however, with appropriate thickness, also be manufactured in the form of rolls. If necessary and justifiable from an economic point of view, the support films can be supplemented by the installation or formation of reinforcing agents.
  • FIG. 4 shows the same support films 1 (2) as in FIG. 1, the butting or overlapping zones la, lb and not shown 2a, 2b, by uniformly distributed, elongated or semicircular depressions 4a, 5a, according to FIG 5, which lead to a connection 6a similar to connection 6 described above.
  • 6, 7 and 8 show a variant which brings the support foils 10 and 11 together to form a connection which is detachable but is characterized by a force fit.
  • the two support foils 10 and 11 are also not all the same: the one support foil has a latching pin 8 along two overlapping overlapping zones, while the rest identify themselves through a latching opening 7. It is therefore not possible to form the support foils on all sides with one another, but rather only in the area of the complementary latching means 7, 8.
  • FIGS. 9 and 10 show a further variant of a composite formation of support foils, the variant shown here producing a releasable connection that can be created with a force fit.
  • This connection takes place with the aid of an insertion pin 9, which connects the support foils 12, 13.
  • These support foils 12, 13 are again compatible on all sides, since the means for this purpose in the butt or overlap foils 1a, 1b and not shown 2a, 2b consist of matching, equally large bores 14.
  • the support films 15 and 16 shown in FIGS. 11 and 11a and 12 have similar butt or overlap zones as the previous embodiments. As far as the connection is concerned, one of the previous variants described can be provided here, which is why, for the sake of simplicity, the corresponding description is not repeated here.
  • the depression 17 shown is square in cross section.
  • the overlap zones la, lb, 2a, 2b lie in the film plane.
  • a horizontally circumferential zone 17a separates the depression 17 into two truncated pyramids, the side surfaces 18 of the upper truncated pyramid 19 being flatter than the side surfaces 20 of the lower truncated pyramid 21.
  • reinforcing beads 22 are formed, which one downwards have a tapered, trapezoidal cross-sectional shape.
  • the reinforcing beads 22 begin in the area of the overlap zones and end in the area of the four side edges 23 of the lower truncated pyramid 21.
  • the bottom surface 24 of the depressions 17 is octagonal in the present case.
  • the depressions 17 according to FIG. 12 are indicated with different, high lower truncated pyramids 21, but only the lowest area of the depression, 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 18 of the upper truncated pyramid 19 have the angle of inclination, which is substantially smaller than the angle of inclination ⁇ of the side surfaces 20 of the lower truncated pyramids 21.
  • the angle of inclination ⁇ is in the range of 30-80 °. It can also be seen from FIG. 12 that the depth of the reinforcing beads 22 increases from top to bottom and the bottom of the curve merges tangentially into the flat area 23 of the side edges of the lower truncated pyramid 21.
