Abstract

Each plate (2) lies in part on a support frame whose one side has a sealing profile reaching partly up to the top of the plate along one plate edge. The frame has extensions in the form of profile plugs for mechanical connection to the adjoining plate. The sealing profile is fitted onto frame extensions in two adjoining frame legs. The frame is in one piece or of extruded profiles and can be made of re-cycled material. The four frame legs form the support (5) for the plate, the frame legs cammed on one pair and holed in the other pair of legs to make up the extensions used to connect adjoining plates. The plates are soundproofed (12) underneath by material bonded to the plate.

Description

Laying system for floor slabs Technical area

The invention relates to a laying system for floor tiles and is particularly suitable for stoneware tiles and natural stone tiles as well as wooden panels.

State of the art

Floor tiles, if they are stone or ceramic tiles, are usually laid using a suitable adhesive on a suitably prepared base, e.g. on a smooth screed, whereby the joint width is usually determined by inserting joint spacers and the joints must be subsequently filled. Laying them is relatively complex both in terms of the tools and materials required and also requires a relatively high level of manual skill from the installer. In addition, a lot of time is required before the flooring can be walked on. Another disadvantage is that a flooring laid using this method cannot be removed easily, i.e. not without destroying the tiles.

With wooden panels, for example parquet or laminate panels, as used for floor coverings, it is common to provide a groove on one of the two intersecting sides of the panel and a matching tongue on the other two sides. When laying the panels, panels with corresponding grooves and tongues are butted together and glued together. Here too, the panel covering cannot be removed at a later date without destroying the panels.

to the underside of the panel. In addition, a guide bar can be provided in the area of the support bar to form drainage channels.

The invention is based on the object of specifying a laying system in which the laying of the slabs is relatively easy, i.e. can be carried out even by inexperienced people. The laying system should be particularly suitable for natural stone slabs such as granite, marble, etc., but also for slabs made of wood, ceramic or other materials. It should also ensure that the covering can be removed again if necessary without damaging the individual slabs.

Description of the invention

The installation system proposed according to the invention avoids the aforementioned disadvantages. Each panel rests at least partially with its underside on a support frame having support profiles with support areas, the support frame having a projection that protrudes over the support surface towards the top of the panel and extends at least in sections along the edge of the panel towards the top of the panel. The support frames can be connected to one another. The projection is only provided on two adjacent support profiles, whereas the other two support profiles have a support area without a projection. The first support profiles have at least one locking extension that extends beyond the panel, the other two, second support profiles have at least one locking extension located below the panel and one support profile interacts with another support profile.

In the case of square or rectangular panels, the support frame has a total of four support profiles, whereby

20010145GDEII
Hans Meyer

The special design of the connection allows parallel rows of laid panels to be moved. This makes it possible to lay the panels offset. In this case, four corners do not meet in one corner of a panel, but two corners meet a side edge of the adjacent row of panels.

The rubber joints that seal the individual tiles against each other create a precise, consistent joint pattern that is also impressive due to its watertightness.

Thanks to the invention, expansion joints are no longer required even when laying larger areas, as the floating installation means there is no firm contact with the subfloor. There is therefore no risk of cracks forming in the floor covering or in the individual panels, as is the case with panels glued to the screed. In addition, no adhesives are required for installation.

There are particular advantages when laying high-quality slabs, such as granite slabs or similar slabs, as the additional costs of the laying system are less significant in terms of the unit price and, as a far more important advantage, errors are avoided during laying, even with poorly trained laying personnel. In addition, the laying costs are reduced considerably.

The floating installation makes it possible to lay granite floors quickly and inexpensively on the existing wooden structures when renovating old buildings with wooden floorboards without any major preparatory work. The invention also makes it possible to lay granite and natural stone in prefabricated wooden houses.

The very common problem of inadequate impact sound insulation in existing screeds, which often

20010145GDEII 20.09.20^,2

Hans Meyer

Sound bridges that arise as a result of improper installation no longer occur when the installation system according to the invention is used in conjunction with impact sound insulation, and optimal insulation is guaranteed. For this purpose, the support frames are provided with impact sound insulation on their underside.

In addition to the installation system, the subject matter of the application is a tile for use in an installation system and the floor covering produced with the installation system or using the tile. A further subject matter is a support frame for a panel. Advantageous further developments are described in the respective subclaims.

Examples of implementation

The embodiments shown assume a floor covering that is made up of a large number of stone slabs, e.g. granite slabs, arranged next to one another and laid in a floating manner on a base, e.g. a rough screed or a floorboard, with a spacer joint in between.

Figure 1 shows a diagrammatic representation of a square frame 1 for holding a plate (not shown in this figure), e.g. a granite plate. The frame 1 is made of plastic and is prefabricated; it can consist of a one-piece injection-molded part or of individual elements that are assembled from a rod profile. A recycled plastic can also be used as the material.

Of the four legs la to Id of the frame 1, the two adjacent legs Ic, Id each have a plug-in profile 3 which is shown in cross-section in Figure 4. The other two legs la, Ib have a plug-in profile 4 as shown in cross-section in Figure 5. All four legs la to Id have a strip-shaped support 5 on which a panel 2 which can be inserted into the frame rests when installed.

In Fig. 2a, the support of such a plate 2 on the strip-shaped support 5 with the plug-in profile 4 is shown. The width of the support 5 is for a plate width of

3 05 mm preferably 2 0 mm.

The distance between the underlay (floor screed) and the panel 2 on top, which is determined by the thickness (height) of the support 5 of the frame 1, can advantageously be used to insert impact sound insulation 12. The height of the impact sound insulation 12 is to be measured in such a way that it only corresponds to the said distance from the underlay to the panel when it is under load. The impact sound insulation is advantageously glued to the underside of the panel. This reliably prevents the formation of back noise, which is a known problem in the parquet sector.

Fig. 2b shows the installed state of two plates, although the right-hand plate 2 shown is moved backwards for illustration purposes. The plate 2 rests with its underside in the edge area on the strip-shaped support 5 and is glued to it.

Deviating from Fig. 2a, the impact sound insulation 12 extends not only close to the support 5, but also under it, so that insulation takes place even in the area of the support 5. This is shown with broken lines.

, whereby the area below support 5 is marked with the reference number 13.

If minor unevenness or roughness in the surface of the installation underlay needs to be leveled out, e.g. in the case of a very rough screed, it can be advantageous to additionally glue a flexible foam underlay (not shown) under frame 1. This underlay can be glued on at specific points or across the entire surface.

As can be seen from the illustration in Fig. 4, the plug-in profile 3 of the legs Ic and Id has a vertically upward-pointing projection 6, on both sides of which the panels 2 rest when installed. The projection 6 is provided with a groove 7 into which a rubber seal 8 shown in cross-section in Fig. 6 is inserted. If necessary, the seal 8 can also be glued to the projection 6 of the leg in the groove area, so that it is reliably prevented from being worked out. In addition, the seal 8 is to be produced in a color that matches the color design of the panels. It is therefore not necessary for the frame to be color-coordinated with the panels.

The rubber seal 8 is mushroom-shaped, with the stem 8a of the seal 8 being designed such that it fits into the groove 7 of the extension 6. The hat 8b is preferably trapezoidal and is designed in such a height that its upper edge, when installed, is approximately flush with the upper edge of a panel 2 inserted into the frame, as shown in Fig. 2b.

The width of the rubber seal 8 is at least at the top larger than the width of the extension 6, whereby in the 0 laid state of the panels the rubber seal is pressed together and a gap seal is achieved. At the corners, i.e. at the intersection point of the panels, the rubber seal is

20010145GDEII 2 0.09^.20.0,2

Hans Meyer _t , ,.^ .**♦♦**· J* * * *

8 is mitred at an angle of 90° (Fig. 3) so that a seal is also achieved at the intersection point.

The plug-in profile 3 (Fig. 4) contains an extension 9, which corresponds to a matching locking groove 11 in the plug-in profile 4 (Fig. 5). The two plug-in profiles 3 and 4 thus form a plug-in locking mechanism with which several frames can be easily plugged together and later easily separated again. To ensure that the parts can be easily plugged together without cutting on site, the extensions 9 with the locking cams 10 are set back by a dimension X from the outer edge of the frame on each frame.

Each panel 2 to be laid is provided with a frame as shown in Figure 1. The frames are preferably glued to the underside of the panels so that the panel and frame form a unit. Gluing also has the advantage that the panels are firmly fixed in the panel assembly and "working out" of the panels is avoided even when the finished covering is walked on for a long time.

To lay the panels, with the frames glued to them, they are placed on the prepared base onto which the panel covering is to be laid (in this case, floor screed) and placed together so that the legs with the locking grooves 11 are placed on the legs with the locking cams 10. By joining the parts together (clicking them in), a mechanical connection is created which can be removed later if necessary. When joining the parts, as already mentioned, the rubber seal 8 is also pressed together to such an extent that a certain pre-tension is created. The pre-tension ensures adequate sealing against the ingress of dirt and moisture. In addition, tolerances can be compensated for when laying the panels.

Fig. 7 shows a further locking connection in which the locking cam 10 projecting beyond the leg Ic has undercuts on its top and bottom, which lock into a groove 11 on the receiving leg la, which also has two undercuts. When the locking cam penetrates into the locking groove, it spreads open and snaps back together after it has been fully inserted and the side edge of the leg la has been placed against the side edge or the projection 6 of the leg Ic. The elasticity of the material is selected so that this can be done without causing any damage.

In Fig. 8, the locking connection in the area of a projection 14 and a groove 15 is itself designed without undercuts, so that only a guide takes place here. The mechanical securing takes place via a locking cam 10 on the underside of the projection 14 and a locking recess 11 in the surface of the lower side wall of the groove 11. To facilitate assembly, an insertion bevel 16 can be provided, which is indicated by dashed lines.

In Figs. 4, 5, 7 and 8 it is particularly clear that the female plug profile 4 engages under the male plug profile 3 on the underside to a certain extent, namely by the width of the extension 6.

Fig. 9 shows a further embodiment of the invention. In addition to the edge profiles 21a, b, c, d located on the edge, a support frame 21 here consists of stiffening ribs 22, 23, of which a first group 22 is parallel to the sides and a second group 23 is in the diagonal direction. The ribs 22, 23 cross each other so that crossing points 24 are created. These crossing points can be of different sizes.

Upper and lower projections 25, 26 are formed on the edge profiles 21a to d, each of which represents one half of a locking connection, namely the upper half and the lower half respectively. This will be explained in more detail below. Each field of support area 27 delimited by ribs on the edge profiles 21a-d and by the 22, 23 has openings, indicated by the dots, the function of which will be explained later.

Fig. 10 shows a cross section through the support frame according to Fig. 9, where the side profiles 21b, 21d can be seen in the edge area. In addition, the course of the web 28 can be seen. The web 28 extends from the profiles 21a to d over almost the entire length or width of the support frame 21, but only on two adjacent sides. In Fig. 9, this can be seen by the web 28 arranged on the profile 21a and the web 29 arranged on the adjacent profile 21b.

Fig. 10 also shows the openings 30 and the internal ribs 22. Also visible are an upper and lower part 25, 26 of a locking connection.

In Fig. 11, the left side is shown as section AA from Fig. 9, the right side of Fig. 11 corresponds to a neighboring panel according to the invention. Firstly, the frame profile 21 is shown with the edge profile 21a, on which a panel 2 rests and is fixed in its position by the web 28 acting as a stop.

The support frame 21 is provided with openings 3 0, which will be explained later.

On the outside of the support frame 21, an upper projection 25 is shown, which has a downwardly directed locking toothing 31. The transition area of projection 25 in

the frame profile 21a is designed to be elastically springy, so that the projection 25 has a certain flexibility.

In the right-hand part of Fig. 11, an adjacent base plate is provided, the edge structure of which corresponds to section BB in Fig. 9. The plate 2' rests on the edge profile 21c, which has a lower projection 26 with a locking toothing 32. The plate 2' also overlaps the lower projection 26, so that when the base plates 21, 21' are joined together, the plate 2' comes to lie above the upper projection 25 of the edge profile 21a. This installation situation for the plate 2' is shown on the left-hand side of Fig. 11, whereby the lower projection 26 of the support profile 21c lies below the upper projection 25 of the frame profile 21a. The upper projection 25 is thus enclosed on both sides. In order that the upper locking projection 25 can nevertheless slide over the locking teeth, a distance to the plate 2' is provided so that the upper side of the locking projection 25 is lower than the underside of the plate 2' or the support surface of the plate 2.

The plates 2, 2' are held at a predetermined minimum distance from one another via the web 28, with a seal 33 attached to the web 28 sealing the plates from the top. For this purpose, the seal 33 is widened in a wedge shape towards the top and has a sealing lip 34, 34' in the area of the shaft that extends to the plate 2 or 2'. When the plates are joined together, the wedge-shaped end of the seal 33 with the inclined surfaces comes into contact with correspondingly designed inclined surfaces on the plates 2, 2' and thereby creates a seal. If moisture, such as an applied cleaning fluid, does penetrate through these sealing surfaces, the sealing lips 34, 34' prevent further leakage downwards.

The support frame is also provided with a receiving groove 35 on its underside, in which an insulating profile 36 is inserted. The insulating profile 36 protrudes beyond the lower edge of the frame profile 21a and can have lateral compensation spaces 37, 37', which enable the insulating profile 36 to deform under load. In addition to the support profiles 21a, the stiffening ribs 22, 23 are also provided with an insulating profile embedded in a groove, so that good impact sound insulation is achieved.

Fig. 12 also shows a section along the line AA, but here the arrangement of the opening 30, 30' and the support webs 38 of the support area 27 lying between them can be seen. Of particular importance is the course of the side walls of the webs 38 such that the opening 30 widens from the support surface for the plate to the underside of the support frame 21. This enables the plate to be mechanically anchored in the support frame 21 by means of adhesive passing through the opening 30. The plate (not shown) is also mechanically firmly connected to the support frame 21 as a result, since a type of dovetail connection is created.

There is a gap between the underside of the support webs 38 or the openings 30 and the underside of the support web 21a. The adhesive is applied to the top of the support web 38 by machine using a squeegee, for example. Alternatively, only the back of the plate can be coated with adhesive, or both. It is not always necessary to bond the entire surface. In some cases, it is sufficient to coat only partial surfaces with adhesive, and the adhesive can also be applied in the form of an adhesive bead.

Thermoplastic adhesives, so-called hot melts, can be used as adhesives, but also single- or multi-component reactive adhesives, in particular polyurethane (PU) adhesives with slight foaming behavior.

The upper and lower projections 25, 26 can also be seen in Fig. 12, although the projections 25, 26 on the support profile 21a are not opposite one another but are offset by a distance into the plane of the drawing, as can be seen in Fig. 9. However, the interaction of the locking teeth can be clearly seen here. At this point, it should be noted that the lower projection 26 also has an elasticity in order to allow the locking teeth to slide past. However, additional space for escape is not provided here, since it is assumed that the entire plate can also be lifted when the locking connection is released. This means that the locking connection can be released even if the upper locking projection is supported directly on the underside of the plate.

Fig. 13 shows a section of the bottom right corner of Fig. 9. Here, the course of the edge profiles 21a, 21d as well as the protruding web and a diagonally running reinforcing rib 23 as well as a reinforcing rib 22 running parallel to the support profile 21a can be seen. Both the support profiles 21a, 21d and the reinforcing ribs 22, 23 have an insulating profile 36, which can be injected into the grooves 35 provided for this purpose via a central injection point 40 in the area of the intersection point 24 after the support frame has been manufactured in a first injection process. The support surface between the edge profile 21a and the reinforcing rib 23 is provided with openings 30, 30', between which the support webs extend.

In Fig. 14a, a section through the support profiles 21a, 21d is again shown, wherein it can again be seen that only the edge profile 21a is provided with the web 28, which acts as a stop for the plate, whereas the support profile 21d does not have such a web.

As already mentioned, the panel is connected to the support frame using an adhesive technique, for example. Hot glue or a hardenable adhesive can be applied in such a way that the adhesive passes through the conically widening openings 3 0 and creates a mechanical anchor. A normal adhesive connection is present on the support surface between the openings, so that after the adhesive has hardened, the panel is attached both by the adhesive connection and by the mechanical anchor in the manner of a dovetail connection.

The support frame can be provided with the thermoplastic elastomer and the seal 33 for the impact sound insulation 3 6 using a two-component injection molding process, whereby a hard plastic material such as polystyrene or polyurethane can be used for the frame itself and a thermoplastic elastomer TPE can be used as impact sound insulation.

The locking teeth can also be single-locking using a single projection or, as in the example, multiple-locking, so that dimensional differences can be compensated if necessary. The locking connection is to be designed in such a way that when the plate is lifted at the opposite edge, the lever effect

loosening is possible. In the case of purely tensile stress on flat-laid panels, loosening should only be possible after the usual loads have been exceeded.

The one-sided snap-in connection of the second embodiment has the advantage that the installation height is significantly reduced compared to a plug-in connection.

The impact sound insulation is embedded in the support surface, in the example in the reinforcing ribs 22, 23 and the edge profiles 21a to d. This also makes it possible to achieve a low construction height. The impact sound insulation can be designed in such a way that an additional anti-slip effect is achieved.

The floor plate made up of the plate and support frame has increased static strength due to the adhesive connection, so that the required plate thickness in the case of granite plates can be reduced from 10 mm to 8 mm or even to 6 mm. This leads to considerable material and therefore cost savings in the production of a floor covering.

As already mentioned above, the insulation profile 3 6 protrudes over the underside of the edge profiles 21a - d or the reinforcing ribs 22, 23, whereby the underside of the support profiles or reinforcing ribs also come into contact with the support under extreme loads and thus prevent the impact sound insulation from being destroyed. The impact sound insulation embedded in a groove is therefore protected against damage under extreme loads.

The adhesive itself must be selected so that sufficient thermal stability is ensured when underfloor heating is used. If the floor is to be laid outdoors, the adhesive must be weather-resistant.
