Definitions

  • the invention relates to a floor covering for roadways, in particular for runways, consisting of releasably connected sections of sheet metal plates, which is provided on its underside with longitudinal webs engaging in the pre-consolidated soil, the inner webs being formed by beads pointing downwards ( see AT-B 244 379).
  • the longitudinal webs are welded to the underside of the covering plates (DE-AS 2345457). This requires considerable effort because the welding must be carried out very carefully. On the one hand, the weld must be sufficiently stable so that the webs do not break off; on the other hand, the lining plate must not warp during welding. In addition, the webs must first be brought into a predetermined position and held in this position during the welding process.
  • the invention has for its object to design the flooring of the type mentioned so that it can be produced in a simple manner without welding, without having the disadvantages of the aforementioned known flooring.
  • the outer webs are formed by the lateral edges of the sections angled at right angles to the covering plane and the inner webs are formed by completely compressed beads; that further webs are provided on the underside of the sections, which form an angle with the longitudinal webs; and that the sections at a certain distance from each of their edges each have at least one recess for inserting a connecting clip or an edge piece.
  • the webs are formed in a single operation, since only bending operations have to be carried out. Furthermore, the design of the sections of the floor covering according to the invention ensures that the predetermined distances between the webs are exactly maintained. Since the webs are part of the sections of the floor covering, they cannot break off even if the sections or the floor covering are handled improperly, as occurs with welded-on webs.
  • the angle which the further webs form with the longitudinal webs can be 90 ° or less.
  • the other webs must be welded to the sections, as in the known floor covering. However, since it is sufficient to simply weld the further webs to the longitudinal webs, the sections cannot warp.
  • the attachment of the further webs is further facilitated by the fact that the further webs extend over the clear width existing between the outer longitudinal webs of a section and are provided in the areas of the inner longitudinal webs with punched-open openings, the shape of which is the shape of the inner longitudinal webs is adapted. This also prevents the beads forming the longitudinal webs from opening, so that a further welding process on the longitudinal webs in the longitudinal direction is eliminated.
  • the recesses are designed as elongated holes that run parallel to the relevant edge of the section.
  • Such recesses can be produced, for example, by punching out.
  • the assembly of the floor covering can be carried out in a simple manner through the recesses for inserting the connecting clip.
  • the assembly of the floor covering is also very simple if the connecting clip is formed from a metal band, one end of which is bent in a hook shape and the other end of which is angled, the angled end having an inwardly directed bead.
  • the connecting clip is formed from a metal band, one end of which is bent in a hook shape and the other end of which is angled, the angled end having an inwardly directed bead.
  • the inwardly directed bead causes the connecting clip to be resiliently clamped so that it cannot be released without mechanical intervention.
  • the connecting bracket is driven in, its angled end engages in the pre-consolidated soil and braces there in such a way that the connecting bracket does not come loose when the floor covering is loaded. Because of its simple design, the connecting clip can be produced in a single operation.
  • the edge piece that may be required is formed from a metal band with a downward, longitudinally compressed bead and has on its side facing a section at least one tongue formed by cutting the edge at at least two closely spaced locations and bending the part of the edge located between the interfaces and is provided with holes on the side facing away from the section.
  • the tongue is dimensioned and arranged such that it can be inserted into one of the recesses in the section.
  • the holes are used to dowel the edge piece on the substrate.
  • the edge piece can also be produced in a single operation, since only bending and punching operations have to be carried out.
  • the floor covering according to the invention has the advantages that no unintentional loosening or moving of parts is possible and that the replacement of possibly damaged parts or edge pieces requires very little effort.
  • the individual sections of the floor covering are less than 50 kg in weight and can be laid by hand with simple aids without heavy equipment; they ensure a level rolling surface.
  • the static function is taken over by the pre-consolidated surface after shaking.
  • a further advantage of the floor covering according to the invention with regard to the load-bearing capacity is given in that the partial pieces of the floor covering can also be installed offset.
  • the floor covering consists of sections 1, which are detachably connected to one another by means of connecting clips 2, and of edge pieces 3.
  • the sections 1 are provided on their underside with longitudinal webs 4 and 5, the outer webs 4 being formed by the downwardly angled lateral edges of the sections 1 and the inner webs 5 by downwardly compressed beads. Furthermore, further, transverse webs 6 are provided on the underside of the sections 1. The transverse webs 6 can - as shown - run perpendicular to the longitudinal webs 4 and 5; but they can also form a different angle with the webs 4 and 5.
  • the sections 1 have, at a certain distance A from each of their edges, recesses 7 which, in the exemplary embodiment shown, are designed as elongated holes running parallel to the relevant edge of the section 1.
  • the connecting clips 2 or the edge pieces 3 can be inserted into these recesses 7 (cf. FIGS. 3 and 4).
  • the edge piece 3 shown consists of a metal strip which is provided with a downward, longitudinally compressed bead 8.
  • the edge section 3 On its side facing a section 1, the edge section 3 has a plurality of tongues 9, which are formed by cutting the edge at two closely spaced locations and bending the part of the edge located between the interfaces 10 (cf. also FIG. 2).
  • edge piece 3 On the side facing away from section 1, edge piece 3 is provided with bores 11.
  • the tongues 9 are dimensioned and arranged such that they engage in the recesses 7 of the sections 1 and thereby produce a releasable connection between the sections 1 and the edge piece 3.
  • the connecting bracket 2 also consists of a metal band.
  • One end 12 of the connecting clip 2 is bent in a hook shape, while the other end 13 is angled.
  • the angled end 13 of the connecting bracket 2 is provided with an inwardly directed bead 14.
  • the hook-shaped end 12 of the connecting clip 2 is first hooked into one of the recesses 7 of one of the sections 1. Then the angled end 13 of the connecting clip 2 is hammered into one of the recesses 7 of the other section 1.
  • the transverse web 6 shown in FIG. 1 is provided with punched-open openings 15, the shape of which is adapted to the shape of the longitudinal webs 5 (see FIG. 1).
