Definitions

  • the present invention relates to an installation floor with stone slabs laid watertight to form an underlying cavity.
  • Installation floors also called raised floors, form an optimal basis for the function-oriented structure, linking and combination of office workplaces.
  • extensive variability in the formation and regrouping of efficiently working subareas is guaranteed.
  • Smooth work processes, unimpeded communication, access to all supply lines are a few keywords for requirements where an installation floor meets all requirements.
  • the panels of a double floor are, for example, square and have a grid of, for example, 50, 60 or 75 cm.
  • the surface formed by the raised floor panels is normally covered with a carpet or a PVC finish.
  • carpet or covering slabs with the grid of the raised floor are particularly well suited because then the slab and carpet or covering can be lifted off at the same time.
  • U, 8710843 discloses a composite panel for raised floors, which consists of an upper and a lower panel made of stone and an intermediate layer firmly connecting the two stone panels made of a glass fiber reinforced plastic.
  • the composite panel is provided with sealing lips on its front sides, in its upper area.
  • the composite slabs made of stone can be lifted off individually, but the problem of the over-teeth is neither mentioned nor is a solution even suggested.
  • the invention has for its object to provide a representative installation floor of the type mentioned, which has all the advantages of a raised floor of a known type and can be easily installed with respect to the tread surface while maintaining an accuracy of about 0.1 mm.
  • the laying accuracy is of great importance because on the one hand stone slabs cannot be manufactured with the same precision as the usual raised floor slabs and on the other hand cannot be covered with a carpet or the like.
  • the object is achieved according to the invention in that the separately liftable stone slabs are arranged individually adjustable in height at each corner, can be lifted off individually and are aligned flush with their tread or slab surfaces.
  • Floors made of natural stone slabs such as granite, marble or travertine are preferred for the representative design of rooms.
  • suitable artificial stone slabs for example made of a ceramic material, can also be used.
  • the stone slabs not only have to give a representative impression, they also have to have a high load-bearing capacity - since they are only supported in the edge area. As a rule, they have to withstand a point load of up to 500 kg.
  • the basic geometric shape of the stone slabs is not essential, but they must be joined together to form a closed surface and be easy to support. For practical reasons, square or rectangular plates are therefore preferred.
  • the stones lie slabs on a known substructure, which in turn is supported by height-adjustable supports.
  • the cavity formed at the bottom ensures the advantages of a double floor of a type known per se, as described at the beginning. Since the stone slabs can be lifted off individually, the cavity is accessible at any time and at any point.
  • the metallic e.g. Substructure made of steel or a high-strength aluminum alloy according to the grid of the stone slabs.
  • an elastic profile arranged between the side walls of the stone slabs, which preferably consists of a rubber or a plastic with corresponding elastic properties.
  • Elastic profiles are particularly suitable, which have support flaps on both sides that extend approximately over the area of the substructure for the edge area of the stone slabs and a central web separating these slabs. At least part of the underside of the support tabs is preferably provided with an adhesive layer, which allows a detachable connection of the elastic profile to the substructure.
  • the side walls of the stone slabs are preferably beveled, which causes gaps to expand downwards after the stone floor has been laid.
  • the stone slabs according to this first variant are provided or underlaid with one or more calibration plates in the area of at least one corner. These plates, which are usually metallic, allow an adjustment accuracy of about 1/10 mm.
  • the corner areas of the stone slabs are supported by height-adjustable supports.
  • These beams can optionally support one or more plates at a time. They lie directly on the bare floor or on a double floor of a known type.
  • a corner of a single stone slab supporting beams are used in relatively large numbers, they must be able to be produced with little effort, consist of an inexpensive material and be adjustable in a short time with simple means. Furthermore, these carriers must have a high load capacity and should be adjustable with a precision of about 1/10 mm. Carriers of this type are primarily suitable for a cavity of low height, in particular for a cavity above a conventional double floor orderly stone floor.
  • all of the side surfaces of the stone slabs are preferably convex.
  • the side-by-side convex stone slabs form inwardly narrowing joints on both sides of the mutually abutting surface lines. These absorb dust, which due to the air humidity and penetrating cleaning water quickly cemented and forms a tight seal. This way, no cleaning water can penetrate into the cavity below the stone slabs and have a harmful effect there.
  • the upper space between the stone slabs can also be covered with a joint filler before or after cementing with dust.
  • the above-mentioned convex side surfaces of the stone slabs can have contact surfaces running perpendicular to the surface of the plate in the central area, which contact one another after the installation of a plate with contact surfaces of adjacent stone slabs.
  • a preferred way of laying the height-adjustable stone floor is to mount the first stone slab in a corner and to connect the other stone slabs diagonally row by row.
  • a support namely that of the rear corner, must be set as precisely as possible or, if necessary, the correct calibration plate placed under the relevant corner area.
  • the three supports supporting the front corners can be easily adjusted from the front after placing the stone slab or the correct calibration plates can be placed underneath.
  • the invention is also suitable for assembling stone slabs other than square or rectangular, but is then the effort is usually greater, which increases the price of the representative installation floor as a whole.
  • Fig. 1 shows a section of a representative installation floor.
  • the stone slabs 10 lie on a substructure 12, which is supported by height-adjustable supports 14.
  • the supports 14 comprise a support foot 18 resting here on a raw floor 16 and a rotatable support head 20 with a vertical threaded pin 22, which is screwed into a sleeve 24 with an internal thread that projects vertically from the support foot 18.
  • the height of the support 14 can be adjusted by a rotary movement between the support foot 18 and the support head 20.
  • the substructure 12 essentially consists of metal tubes with a rectangular cross section, which are detachably connected to the support head 20 by means of screws 26.
  • the right-angled arrangement of the substructure 12 can be seen more clearly from FIG. 2.
  • a continuous rectangular tube 28 and two short rectangular tubes 30 are screwed to a column head 20.
  • the joint 32 between two stone slabs 10 is sealed with an elastic profile 34.
  • This profile 34 has two support tabs 36 for the stone slabs 10, which support tabs expediently cover the entire width of the rectangular tube 28 of the substructure 12. Since the elastic profiles 34 extend along the entire stone slab, the cavity 38 is completely sealed against water, which is used for cleaning the stone slabs 10. Furthermore, the stone slabs 10 do not lie directly on the substructure 12, an intermediate space 40 is formed.
  • an insulation layer 44 made of a polyurethane plate is glued, which has a thickness d, approximately corresponding to the height of the rectangular tubes 28, 30 of the substructure 12. This insulation layer 44 does not extend into the edge region of the stone slabs 10 and has a bevel 46. On the right side of FIG. 1, the insulation layer 44 has been omitted for reasons of clarity.
  • the stone slabs 10 have a bevel 48 which extends downwards in the region of the joint 32.
  • the support 14 can rest on a known double floor instead of the unfinished floor 16.
  • the grid of the substructure 12 corresponds to the dimensions of the stone plates 10.
  • FIG 3 shows the joint area of the stone slabs 10 in detail.
  • the stone slabs 10 press with their beveled side surfaces 48 onto the central web 54 of the elastic profile 34 protruding into the joint 32 and thus seal the joint 32.
  • the stone slab 10 on the right is, due to manufacturing tolerances, somewhat thinner than the left stone slab 10.
  • a calibration plate 50 is placed between the underside 42 of the right stone slab 10 and the corresponding support tab 36 of the elastic profile 34.
  • the elastic profile 34 is not exactly in the middle of the rectangular tube 30 of the substructure 12, but this is not important.
  • the variant of the elastic profile 34 shown in FIG. 4 has a central web 54 with a longitudinal opening 56 and longitudinal ribs 58.
  • a dotted adhesive layer 60 is applied, with which the elastic profile 34 is releasably attached to the substructure 12 can.
  • the underside of the plates 62 is covered with a steel sheet 68, the top with an aluminum foil 70.
  • the supports 72 which - which is not shown in FIG. 5 for the sake of simplicity - are arranged under each corner, have a lower wedge 74 and an upper wedge 76 with sliding surfaces 78 lying one above the other with respect to the plane of the plates 62 of the double floor 64.
  • the lower wedge 74 is part of the support body 80 of the carrier 72.
  • the upper wedge 76 can be displaced in the horizontal direction by means of a screw 82, being lifted in the opposite direction when displaced in the direction pointing away from the screw 82.
  • the self-locking screw 82 has a slot 84 at the head into which a screwdriver can be inserted.
  • a carrier 72 is arranged under each corner area of the stone slabs 10. By actuating the screw 82 of the carrier 72, the tread or plate surfaces 52 can be set flush and the formation of over-teeth can be prevented.
  • the setting accuracy of the carrier 72 is approximately 0.1 mm.
  • the side surfaces 88 of the stone slabs 10 have a cambered design and abut one another along a surface line 90.
  • the convex side surfaces 88 can have contact surfaces 92, which are formed perpendicular to the tread or plate surface 52 and which close the inwardly tapering joint 32 lying between two stone plates 10.
  • the cavity 96 formed between the double floor 64 and the stone slabs 10 is usefully used for the impact sound insulation by inserting an indicated insulation mat 100 made of stone wool.
  • the stone slabs 10 are laid starting from the corner formed by the walls 102, 104.
  • the calibration platelets 50 (FIG. 3) or the carriers 72 (FIG. 5) which are underlaid if necessary are indicated with a short line 106.
  • the stone slab 10 labeled A is laid, then the stone slabs 10 labeled B, then the stone slabs 10 labeled C and finally the stone slabs 10 labeled D.
  • This laying method is particularly advantageous when using beams 72 according to FIG. 5 because before placing a stone slab 10, the rear support 72, after placing the front three supports can be adjusted.
  • the direction of the line shows the direction in which a screwdriver can be used to adjust the carrier 72.
