Definitions

  • the invention relates to a method for producing a polygonal composite panel for raised or hollow floors arranged on supports according to the preamble of patent claim 1.
  • Composite panels of this type are used in large quantities for floors, under which there is a cavity in which lines of all types are laid.
  • the individual slabs which are also referred to as “raised slabs", are laid in a regular grid dimension, the slabs being to be laid close to one another and the slabs also having to be secured against transverse displacement.
  • a main area of application for such panels is flooring in office rooms, in particular those in which data processing devices are located.
  • the various office facilities require a large number of lines, which are "hidden” under the raised floor slabs and can be led out directly under the connection point through the floor.
  • other supply lines can also be laid in the cavities, as can so-called underfloor heating systems.
  • Such panels have to meet a whole range of requirements: they have to be insensitive to impact and shock, punctiform and rolling heavy loads and to a large extent also resistant to high temperatures, with fire protection being the primary consideration here.
  • the plates must also be covered with a floor covering, either with a suitable plastic plate or with plates that form a so-called carpet.
  • DE-AS 23 07 815 discloses a method of the type specified at the outset and a floor slab produced by the method: in a profiled trough referred to as formwork, which can consist of metal as well as plastic or of a mineral or fiber material, a curable, originally mushy or viscous, preferably mineral mass is poured in and smoothed out.
  • the tub or bowl As far as the tub or bowl is made of metal, it has the disadvantage of undesirable good heat conduction and a different coefficient of expansion compared to the filled and hardened mineral mass. Furthermore, the complicated shape of the shell base with a concave curvature and cross-shaped depressions makes it necessary for the shell to be deep-drawn. This requires expensive deep-drawing tools, as well as the production and storage of different deep-drawing tools for different plate sizes.
  • the shell is made of plastic, mineral or fiber material, this also makes a mold, at least one casting mold or compression mold necessary, because the specified gluing of individual parts would be an extraordinarily labor-intensive process with the complicated shape, which is already eliminated from practical considerations .
  • a plate formed by folding is known, which should be as thin or flat as possible and should preferably be used as a decorative wall covering surface. Plywood is again indicated as a possible material for this. If the plate contains a cavity, this should be for Purposes of air pockets can be divided into individual sub-chambers by a spacer grille or spacer strips.
  • EP 0 295 417 A2 discloses a further double floor slab according to the generic term, which consists of an external reinforcement made of tensile material and a filling made of pressure-resistant material.
  • a tub made of sheet steel should be provided with a filling made of concrete or anhydrite.
  • the tub should be provided in the edge area with special stiffening elements, for example with inwardly folded wall parts or welded profile rails, in order to achieve the required strength, or the edge strength of the filling compound should be increased.
  • the production of a flat, firm connection between the tub and the filling compound is not disclosed.
  • the punches provided in the side walls cannot guarantee a flat connection.
  • the production is also very expensive.
  • the invention is therefore based on the object of specifying a method of the type described at the outset, which can be used in mass production, is based on simple to manufacture preliminary products and, even in the case of the production of such plates in different dimensions, does not require the storage of different molding tools for the shell or Tub required.
  • the composite panel is said to be considerably heat-resistant.
  • the flat plate according to feature a) is a preliminary product which, apart from the thickness and at least two layers, is not subject to any dimensioning regulations.
  • the tensile rigid component can consist of one of the numerous known curable mineral materials, such as gypsum, concrete, anhydrite and the like.
  • the tensile strength of such mineral materials can be achieved by fibrous or textile fillers, for example by glass or other mineral fibers, metal fibers, etc. With concessions to heat resistance, organic fibers or fabric inserts can also be used.
  • Laminates made of non-woven fabrics and fabric webs with mineral binders and chipboards with organic and inorganic binders such as cement and gypsum bindings can also be used.
  • the thickness should be at least 4 mm.
  • thin, soft metal foils are preferably used, for example aluminum foils, which not only have high corrosion resistance, but can also be folded with sharp edges without the risk of breakage.
  • aluminum foils which not only have high corrosion resistance, but can also be folded with sharp edges without the risk of breakage.
  • the foldable component can also be made from a plastic film with and without glass fleece reinforcement as well as coated glass and textile fabric.
  • the opening angle of the V-shaped notches is "approximately 90 degrees" is intended to express that, for example, the side walls of the tub need not be at an angle of 90 degrees to the floor area.
  • the outer surfaces of the side walls it is customary to arrange the outer surfaces of the side walls at an angle of between approximately 2 and 5 degrees to the normal direction on the composite panel delimited by plane-parallel surfaces. It goes without saying that the angle of the notches takes this special feature into account.
  • the unfolding of the individual wall elements according to feature d) is an extremely simple measure to carry out because it is foldable, flexible
  • the outer layer forms the hinges for the unfolding process.
  • the composite panel produced according to the invention is at least flame retardant and has an advantageous poor thermal conductivity.
  • the heat conduction observed when using metal trays does not take place from the underside of the plate to the top of the plate, on which a less heat-resistant material may be located.
  • the "rigid, non-metallic component" for the manufacture of the tub need not be a purely mineral component. It has already been stated above that organic fillers and binders can also be used. However, gypsum fiber boards, cement-bound or gypsum-bonded particle boards or similar material are preferred.
  • the rigid non-metallic component of the plate is provided with openings before it is combined with the flexible component, which openings are closed again on the outside by the combination with the flexible component.
  • the casting compound penetrates into the said openings, it being possible for ventilation of the cavities to be ensured by means of an optionally provided perforation.
  • the subsequent reclosing of the openings with the flexible component prevents the casting compound from escaping through said openings and possibly having to be smoothed out again.
  • the production of the composite panel according to the invention can be carried out in a manufacturing plant, whereupon the finished composite panels are then transported to a construction site and laid there.
  • the composite panels can also be taken up again individually. It is particularly useful to do this before laying the tubs to be provided with the necessary support elements, which are preferably height adjustable. In the latter case, the height adjustment is expediently carried out through the tub cavity.
  • the underside and the side walls of the tubs are not provided with openings in order to prevent the casting compound from flowing out.
  • the outer wall elements are expediently provided with particularly large openings in order to achieve as complete a filling of the tubs as possible.
  • the invention also relates to a polygonal composite panel for raised or hollow floors arranged on supports according to the preamble of patent claim 7.
  • Such a polygonal composite panel is in accordance with the invention to achieve essentially the same object characterized by the features in the characterizing part of patent claim 7.
  • a composite panel 1 which has a square plan.
  • the plates can also be rectangular, hexagonal or octagonal.
  • the plate consists of a trough 2 arranged in the tensile stress area and made of a tensile material, which has a bottom area 3, inner wall elements 4 and outer wall elements 5.
  • inner and outer wall elements relates to their relative position within the blank shown in FIG. 2. To be more precise, it is essentially the Floor area 3 in the so-called tension area of the composite panel.
  • the blank 8 according to FIG. 2 was produced from a plate-shaped primary material, which consists of a tensile, rigid, non-metallic component 9 and a foldable, flexible component 10.
  • component 9 consists of plasterboard with glass fiber inlays.
  • the opening angle of the notches 6 and 7 is about 90 degrees, with deviations due to the later inclination of the inner wall elements 4.
  • the apex lines 6a and 7a of the notches 6 and 7 lie in the immediate vicinity of the surface of the uninterrupted flexible component 10, so that the apex lines 6a and 7a form the fold lines when the tray 2 shown in FIG. 1 is unfolded. In the final state, the fold lines form the lower and upper edges 11 and 12 of the composite panel 1.
  • the tub 2 has two fold-out wall elements 4 and 5 on each side of the circumference of its bottom region 3, the notches 6 and 7 being made in such a way that two are formed when the tub is formed Folding operations made can be.
  • the inner wall elements 4 are folded up by a little less than 90 degrees, and subsequently the outer wall elements 5 are folded around by a second folding process until they run parallel to the base region 3. This state is shown in Figure 1.
  • the inwardly directed end edges 13 of the outer wall elements form a polygonal opening which is used to introduce a hardenable casting compound 14.
  • the mineral component of the plate-shaped primary material is provided at least in the bottom area 3 with openings 15, which are also filled when poured through the casting compound 14, so that the casting compound 14 forms an intimate connection with the tub 2.
  • at least the outer wall elements 5 are also provided with openings 16, which, however, are not visible in the final state according to FIG. 1, because in this position they are covered by the flexible component 10 (dashed line).
  • the notches 6 and 7 respectively provided in pairs or their apex lines 6a and 7a each have the same distance from one another. So that the corners of the outer wall elements 5 do not interfere with each other, they are bevelled accordingly at their corners so that they abut on miter joints 17.
  • FIG. 1 also shows that a circumferential gap 18 is formed between the base region 3 and the outer wall elements 5 running parallel thereto, which is also filled by the cast material.
  • a composite panel produced in this way has a high strength against an impact or impact applied from above and against rolling movements of heavy objects.
  • the composite panel has a very low thermal conductivity, so that in the event of a fire, high temperatures occurring on one side of the composite panel cannot be transferred to the opposite side of the composite panel for a short time. If the flexible component is made of a metal foil or a thin sheet there is a simple way to discharge electrostatic charges by appropriately trained supports.
  • Such composite panels are usually placed in the area of their corners on supports which are preferably adjustable in height. With the exception of room corners and near walls, four corners meet each other in the area of a column if the panels are square or rectangular. Each corner then covers a quadrant of the column. However, it is also possible to provide a single support in the area of each corner of the composite panel. The result of this is that the composite panel is subjected to bending stress upon loading, the tensile forces being absorbed essentially by the base region 3 of the trough 2.
  • the originally outer wall elements 5 lie with their upper side in the upper surface of the finished composite panel and thus in the compressive stress range. This is also advantageous because it creates a high compressive strength. Finally, the part of the flexible component lying in the upper surface is particularly well suited for adhesive bonding with a surface covering, so that the risk of this surface covering becoming detached is considerably reduced.
  • FIG. 4 shows a variant of the object according to FIG. 1:
  • a grid frame 19 is embedded in the casting compound 14, the details of which are explained in more detail with reference to FIG. 5:
  • the lattice frame 19 consists of two rectangular or square congruent frame parts 20 and 21, the individual profile parts of which are L-shaped in cross section.
  • the one leg of each frame part lies in one plane, and the other legs run perpendicular to it.
  • a circumferential gap 23 is present between the legs 20a and 21a of both frame parts lying in one plane, in FIG to which a mesh 22 made of steel wire is fixed, for example by spot welding.
  • the two other legs 20b and 21b are directed away from each other, and their outer sides lie in four common planes which are perpendicular to the plane in which the mesh 22 is located.
  • the legs 20b pointing upwards in the position of use have a greater leg length than the legs 21b below. It is thereby achieved that the mesh in the position of use has a greater distance from the top of the casting compound 14 than from the bottom thereof, which has a common interface with the bottom region 13 of the trough 2. It is important that the mesh 22 is in the tension area of the composite panel. As a result, and in particular through the frame parts 20 and 21, the strength of the composite panel is increased significantly.
  • the mesh 22 can, as shown in Figure 5, consist of a steel wire fabric. However, perforated sheets, expanded metal or simply crossing bars can replace it. It is only important that those volumes of the casting compound 14 which are above and below the mesh are inseparably connected to one another through the mesh. In addition, it is of course necessary that the casting compound can pass through the mesh as freely as possible, regardless of whether the casting compound is filled through the polygonal opening of the top of the tub or through an opening in the bottom region 3 of the tub 2. It can it may be appropriate to fix the lattice frame 19 against the tub 2 before pouring the casting compound.
  • Figure 4 also shows that the special manufacturing process of the tub by folding leads to the additional advantage that a lattice frame of relatively large horizontal dimensions can be accommodated in a tub which has a relatively small filling opening for the casting compound. Nevertheless, it is possible - if necessary using special spacers - to embed the reinforcement in the casting compound in such a way that it is surrounded on all sides by the casting material.
