Description

I. Area of application

The present invention relates to a plate support for supporting at least one floor plate using an adhesive, wherein the plate support has one or more storage areas for supporting a corner area of a floor plate. The floor plates can be, for example, plates for terraces of all kinds or balconies. The floor plates can be made of, for example, a stone material, a concrete material, marble or the like.

II. Technical background

Plate supports for supporting floor slabs using an adhesive are known in various variants. On the one hand, there are stilt supports as shown in Fig. 2a, 2b and 2c of the EP 4 015 735 A1 shown type and on the other hand flat bearings of the type shown in the Fig.1 , 3a, 3b, 3c and 4 the EP 4 015 735 A1 shown type.

The well-known slab supports are placed on a prepared surface and the floor slabs are laid in such a way that each slab support that is not located at the edge of the floor covering supports or supports a total of four individual corner areas of four different floor slabs. Wall-like spacers are arranged on the slab supports, which engage in the joints between the floor slabs and thus ensure a uniform joint width or a uniform joint pattern of the floor covering consisting of the floor slabs.

In order to ensure a firm bond between the corner areas of the floor slabs on the one hand and the slab support on the other, it is known to apply viscous adhesive to the slab support before the floor slabs are laid down. In plate bearings used in conjunction with viscous adhesive, displacement spaces are formed into which the adhesive can be displaced before hardening. Examples of such displacement spaces can be seen on the plate bearings according to Fig. 3a, 3b and 3c of the EP 4 015 735 A1 to see.

Of those from the EP 4 015 735 A1 Of the known bearings, the one according to Fig. 3b has the largest displacement space for the adhesive. It is located in the form of the recesses 224 between the raised, upwardly projecting support knobs 228.

In practice, an excessive amount of adhesive is often applied to the slab support. It is therefore necessary to provide sufficient displacement space for the adhesive even when applying an excessive amount of adhesive in order to avoid the formation of an excessively thick layer of adhesive that extends upwards beyond the support studs 228 and can hinder sufficiently precise leveling of the floor slabs.

The bearing according to Fig. 3b of the EP 4 015 735 A1 not yet available. It could be increased by reducing the cross-sections of the support studs 228 and/or omitting individual support studs 228 without replacement. However, this would result in the network of support points formed by the individual support studs 228 becoming significantly coarser and the corner areas of the floor slabs would be less well supported.

III. Description of the invention a) Technical task

It is therefore the object of the present invention to provide a plate bearing which is designed to support at least one floor plate using an adhesive, in which the largest possible displacement space is available for receiving adhesive and which can nevertheless ensure the closest possible network of support points for the corner areas of the floor plates.

b) Solution to the task

This object is achieved with a plate bearing having the features of claim 1. Further embodiments of the present invention emerge from the subclaims.

According to the invention, a plate support for supporting at least one floor plate using an adhesive is proposed, wherein the plate support has at least one support area with a support area surface. In the support area, at least one support knob is arranged, which protrudes in a raised manner in the direction of the floor plate to be supported, i.e. generally upwards, from the support area surface. At its end facing the floor plate to be supported, the support knob has a support surface for supporting a floor plate. The floor plate can be supported in the support area of the plate support in such a way that it can be supported in contact with the support surface by means of the support knob.

According to the invention, the support knob is formed by a knob wall that surrounds a knob cavity that serves or is designed to accommodate the adhesive for bonding the base plate to the bearing area. For this purpose, the knob cavity is preferably provided at its end facing away from the support surface, i.e. usually closed at its lower end by means of a studded base so that adhesive introduced into or displaced from the studded cavity cannot escape downwards from the studded cavity.

The studded wall, which forms the support stud protruding from the storage area surface, has the advantage that a wall profile can be selected that allows the closest possible arrangement of support surfaces to support the floor slab in the storage area. The hollow space surrounded by the studded wall can always be used as a displacement space for the viscous adhesive. The wall profile viewed from above from the direction of the floor slab to be stored can have any suitable geometry. For example, circular, square, rectangular, star-shaped or elliptical wall profiles are conceivable in the top view.

It has proven to be advantageous to design the stud wall with a circular geometry when viewed from the direction of the floor slab to be supported. This geometry offers a comparatively low flow resistance to the adhesive that flows along the stud wall during displacement. This accelerates and facilitates the displacement process.

Advantageously, the stud cavity has a cavity depth, viewed from the direction of the floor slab to be stored, which is essentially equal to a wall height by which the stud wall protrudes from the storage area surface in the direction of the floor slab to be stored. In this case, the stud wall has the same height on its inner side facing the stud cavity as on its outer side facing away from the stud cavity. As a result, per unit area, the same amount of adhesive can be absorbed inside the stud wall, i.e. inside the stud cavity, as outside the stud wall.

The stud wall can have an outer wall surface facing away from the stud cavity, which is inclined relative to the flat bearing area surface by an outer angle that is preferably greater than 0° and less than 180°. If the external angle is greater than 90° and less than 180°, an undercut is created on the outside of the studded wall when viewed from the direction of the floor slab to be supported, in which adhesive can collect. After the adhesive has hardened, a positive connection is formed between the adhesive and the studded wall or the slab support. If the external angle is less than 90° and greater than 0°, such an undercut does not occur. An external angle in the range of 70° to 110° has proven to be advantageous. If an undercut is to be present on the outside of the studded wall, it is preferable to choose the external angle in a range greater than 90° and equal to or less than 110°.

The studded wall can have an inner wall surface facing the studded cavity, which is inclined relative to the bearing area surface by an inner angle that is preferably greater than 0° and less than 180°. If the inner angle is less than 90° and greater than 0°, an undercut is created on the inner wall surface when viewed from the direction of the floor slab to be supported, in which adhesive can collect. After the adhesive has hardened, this creates a positive connection between the adhesive and the studded wall or the slab bearing. With an inner angle of 90° or more and less than 180°, such an undercut does not occur. An inner angle in the range of 70° to 110° has proven to be advantageous. If an undercut is to be present on the inside of the studded wall, it is preferable to choose the inner angle in a range of 70° or greater and less than 90°.

It is conceivable to make the outer angle and the inner angle the same size. The wall thickness of the studded wall is then the same across its entire height, ie from the bearing area to the support surface at the free end of the studded wall. In this case, there is either an undercut on the outer wall surface or on the inner wall surface, or the studded wall has no undercut at all (the outer angle and inner angle are both 90°).

Advantageously, the outer angle can be made smaller than 90° or larger than 90° and the inner angle smaller than 90° or larger than 90°. In this case, an undercut is created either only on the inner wall surface (outer angle and inner angle smaller than 90°) of the studded wall or only on the outer wall surface (outer angle and inner angle smaller than 90°) of the studded wall or on both the inner wall surface and the outer wall surface (outer angle larger than 90° and inner angle smaller than 90°) of the studded wall, into which viscous adhesive can penetrate and, after it has hardened, form a positive connection with the studded wall or the plate support.

In a particularly advantageous manner, the studded wall can have at least one passage channel through which adhesive can pass from the studded cavity into an ambient space outside the studded wall and vice versa. The passage channel can run through the studded wall at a distance from the support surface at the free end of the latter. It has proven advantageous to design the passage channel as a passage notch that is open towards the base plate to be supported and that interrupts the support surface. The studded wall can advantageously have two or more passage channels, in particular evenly spaced from one another.

In a further advantageous manner, the stud wall can be provided with at least two passage channels which are arranged opposite one another in the stud wall and are aligned with one another. As a result, excess adhesive in the stud cavity can flow more easily into the surrounding space outside the stud wall.

Preferably, the bearing area can have several support studs that are spaced apart from one another and arranged next to one another on the bearing area surface. This design of support studs arranged next to one another ensures that the entire hollow space of each support stud is always available as a displacement space for receiving adhesive. Geometrically conceivable stud walls that lie inside one another, are therefore excluded. The hollow space of each support stud should be completely available to absorb adhesive.

If there are several support knobs in the bearing area, the passage channels of at least two of the several support knobs can be arranged such that they are aligned with each other.

In a particularly advantageous manner, the slab support can have at least one through hole which is arranged and formed in the slab support below a region of such a joint which is created when laying floor slabs between two adjacent floor slabs to be supported or between a floor slab to be supported and a surrounding region of a floor covering formed by the floor slabs.

The through hole is arranged and designed in such a way that an anchor leg of an anchor part of a known leveling tool for pressing the floor slab against the slab support in a leveling manner can be pushed through the through hole from an underside of the slab support that faces away from the floor slab to be supported. An anchor foot of the anchor part, however, cannot be pushed through the through hole and can be supported in a form-fitting manner on the underside of the slab support. This allows the anchor leg to protrude into a space above an upper side of the floor slab, where a clamping part of the known leveling tool can be supported on the upper side of the floor slab and can apply a tensile force to the anchor leg. In this way, the floor slab can be pressed against the slab support using the known leveling tool.

If, for example, there are four bearing areas on a slab support, a total of four of the aforementioned leveling tools are used to level the four corner areas of a total of four floor slabs resting on the slab support, i.e. to align the four top sides of the four corner areas flush in a single plane.

In the different figures, the same reference symbols indicate the same parts or elements or functionally corresponding parts or elements. If the same reference symbol appears several times in a figure, it indicates functionally corresponding parts or elements.

In Fig.1 a plate storage 1 can be seen, which is used to store exactly four corner areas of different floor slabs (not shown). The four floor slabs or their corner areas are placed on the Fig.1 The top of the plate bearing 1 is placed from above. The embodiment shown is designed as a flat bearing and is made of plastic using the injection molding process. Alternatively The design of a plate bearing according to the invention as a stilt bearing is conceivable.

The plate bearing 1 has a relatively thin base plate 17 from which its components protrude upwards. As in Fig.1 As can be seen, the base plate 17 has a cross plateau 18 protruding from it. Spacers 20 protrude upwards from the cross plateau 18, which serve in a manner known per se to create evenly wide joints between the floor plates. The spacers 20 divide the base plate 17 into a total of four storage areas 2, each of which has a storage area surface 9 on the top of the base plate 17 in addition to a partial area of the cross plateau 18. Each of the four storage areas 2 serves to support the corner area of one of the four floor plates.

At least in the installed state of the plate storage 1, the base plate 17 and thus each of the storage area surfaces 9 is essentially flat. The respective storage area surface 9 is limited on two sides by two cross arms of the cross plateau 18 and on two other sides by two edges of the base plate 17. Only one of the four storage areas 2 is described in detail below. This description also applies analogously to the other three storage areas 2, which are in Fig.1 you can see.

In the embodiment shown, a total of nine support studs 3 protrude upwards from the bearing area surface 9. The support studs 3 are identical in the embodiment shown, but this does not necessarily have to be the case.

How best to Fig. 1, 2 and 4 As can be seen, each support knob 3 is formed by a circular, closed circumferential knob wall 4, whereby in Fig. 2 For example, three of the nine support studs 3 are marked with the reference number 4. As in Fig. 2 As can be seen, the stud wall 4 surrounds a stud cavity 5, which here has the shape of a circular cylindrical disk in the manner of a coin. The stud cavity 5 has a stud base 19, which keeps the stud cavity 5 closed at the bottom and here is formed by a circular ring surface which, in the embodiment shown, forms part of the bearing area surface 9, ie lies in the same plane as those zones of the bearing area surface 9 which lie outside the stud walls 4.

As particularly in the Fig. 2 and 3 As can be seen, the stud wall 4 in the embodiment shown has exactly two passage channels, which are designed here as passage notches 6. The passage notches 6 are open upwards, ie in the direction facing away from the base plate 7 or the bearing area surface 9. They each connect the stud cavity 5 with an ambient space 7, which is located outside the stud wall 4 and above the level of the bearing area surface 9. Liquid adhesive can thus flow through the passage notches 6, which function as passage channels, from the stud cavity 5 into the ambient space 7 or from the ambient space 7 into the stud cavity 5.

The stud wall 4 forming the respective support stud 3 has a support surface 8 at its free end, i.e. at its end facing away from the base plate 17 or the bearing area surface 9, which in the embodiment shown is formed by two semicircular ring surfaces, which extend over an angular range of slightly less than 180° due to the two existing through-notches 6. As can be seen in the figures, the support surface 8 would be formed by a full circular ring surface if there were not the through-notches 6 but rather through-channels which pass through the stud wall 4 at a distance from the support surface 8. The through-notches 6 present in the embodiment shown interrupt this full circular ring surface, whereby the latter is divided into the two semicircular ring surfaces with an angular extension of slightly less than 180°.

Fig.3 shows a group of a total of three support studs 3 of the nine support studs 3 that are present per bearing area 2. In the embodiment shown, the passage notches 6 of the three support studs 3 of this group are arranged in the respective stud wall 4 in such a way that all six passage notches 6 are aligned with each other. This creates the Fig.3 clearly visible straight flow path which passes through the group of three support studs 3 in the longitudinal direction and is available for the still liquid adhesive during the process of displacing it.

In the embodiment shown, the support surfaces 8 of the support studs 3 lie in the same plane as the cross surface of the cross plateau 18. The corner areas of the floor slabs to be supported can thus rest both on the support surfaces 8 of the support studs 3 and on the cross surface of the cross plateau 18.

In Fig.5 is a sectional view according to section CC of the Fig.4 shown with an example of a selected support knob 3. In the top view according to Fig.4 the four support studs 3 can be seen, which are Fig.1 shown at the bottom left in the storage area 2, which is also located at the bottom left.

In the sectional view according to Fig.5 a part of the flat base plate 17 and the cut support knob 3 can be seen. The cut runs centrally through the two through notches 6.

The stud wall 4 has an outer wall surface 10 which faces away from the stud cavity 5 within the stud wall 4. In the embodiment shown, the outer wall surface 10 is inclined by an outer angle α = 80° relative to the flat bearing area surface 9, as shown in Fig.5 Preferably, the external angle α is in the range of 70° to 110°. If the external angle α is chosen to be greater than 90°, the viewing direction in Fig.5 from above between the outer wall surface 10 and the adjacent zone of the storage area surface 9 an undercut into which the still liquid adhesive can penetrate.

On its side facing the dimple cavity 5, the dimple wall 4 has an inner wall surface 11 which, in the embodiment shown, is inclined by an angle β = 90° relative to the flat bearing area surface 9, ie in right angle to the bearing area surface 9. Since the dimple cavity 5 is limited downwards by the dimple base 19 and laterally by the inner wall surface 11, in the embodiment shown it has a circular cylindrical shape with a relatively small cylinder height in comparison to the cylinder diameter, like a coin. The inner angle β is preferably in the range of 70° to 110°. If the inner angle β is chosen to be smaller than 90°, a gap is created between the inner wall surface 11 and the adjacent zone of the dimple base 19 from a viewing direction in Fig.5 viewed from above, an undercut into which liquid adhesive can still get.

As in Fig.5 As can be seen, the studded wall 4 has a wall height WH measured from the bearing area surface 9 to the plane of the support surface 8. In the embodiment shown, the wall height WH is the same as the wall height WH measured from the plane of the support surface 8 in Fig.5 down to the stud bottom 19 measured cavity depth HT of the stud cavity 5. Alternatively to the Fig.5 With different sized angles α and β, the outer angle α of the outer wall surface 10 can be made just as large as the inner angle β of the inner wall surface 11. For example, it would be conceivable to choose α = β = 90° for both angles or α = β = 80° for both angles.

In Fig.5 Furthermore, a notch depth KT is marked, by which the respective through notch 6 extends from the support surface 8 downwards towards the bearing area surface 9. In the embodiment shown, the notch depth KT is one third of the cavity depth HT. Alternatively, it is conceivable to make the notch depth KT particularly larger up to a maximum notch depth KT that is equal to the cavity depth HT. In the latter case, the through notch 6 would completely interrupt the stud wall 4, since the wall height WH in the embodiment shown is exactly as large as the cavity depth HT. The stud wall 4 would then no longer run closed around the stud cavity 5.

When creating a floor covering, first of all, in a known manner, plate supports 1 are laid on a prepared surface in the required number and at a suitable distance from one another. A viscous adhesive is then applied, for example using a cartridge press, to the support area surfaces 9 and the support studs 3 in the support areas 2 of the plate support 1. The floor panels forming the floor covering are then laid with their corner areas on the support areas 2 of the plate supports 1. In doing so, they displace adhesive protruding beyond the level of the support surfaces 8 or beyond the surface of the cross plateau 18 in such a way that it is distributed on the one hand in the surrounding space 7 and on the other hand in the stud cavities 5 within the stud walls 4.

The sum of the volume of the surrounding space 7 of a storage area 2 and the dimple cavities 5 is relatively large in relation to the volume taken up by the dimple walls 4 in the storage area 2. As a result, a relatively large amount of adhesive can be accommodated in the storage area 2 compared to the prior art. At the same time, the support surfaces 8 are distributed evenly and at a relatively small distance from one another over the storage area 2.

In Fig.1 A total of eight spacers 20 can be seen, which protrude upwards from the slab support 1 in the direction of the floor slabs to be stored and serve in a known manner to engage in the joints between adjacent floor slabs and to ensure a joint pattern with evenly wide joints. The number, shape and arrangement of the spacers 20 can be varied according to practical requirements.

In Fig.1 Furthermore, a total of four through holes 12 can be seen, which completely penetrate the plate support 1, ie the cross plateau 18 and the base plate 17 located underneath. In the embodiment shown, a single through hole 12 is arranged between two spacers 20 and in alignment with them. In the embodiment shown, the through hole 12 has a keyhole-like geometry with a thickened hole area in the middle.

The through holes 12 advantageously make it possible to level the floor slabs laid on the slab support 1 with the aid of a leveling tool 15 known per se, ie to bring the surfaces of the floor slabs flush in the same plane so that there are no longer any steps between adjacent floor slabs or their corner areas in the area of the joints. Four pieces of a leveling tool 15 known per se are in Fig.6 together with the plate bearing 1 according to the invention according to Fig.1 shown.

The leveling tool 15 consists of two components, namely an anchor part 14 on the one hand and a clamping part 16 on the other. The anchor part 14 comprises an anchor leg 13 and a Fig.6 invisible plate-like anchor foot, which is located in Fig.6 below the plate support 1 parallel to the base plate 17. The anchor leg 13 has at its Fig.6 upper end a threaded bolt 21 onto which the clamping part 16 in Fig.6 can be screwed on from above.

In order to make it possible to level the floor slabs using the leveling tool 15, the clamping part 16 is first unscrewed from the anchor part 14. Before placing the slab support 1 on the prepared surface, the anchor part 14 is then screwed into Fig.6 from below with the threaded bolt 21 first through the through hole 12 so that it is as in Fig.6 can be seen protruding upwards from the plate bearing 1 (but without the Fig.6 also shown clamping part 16).

Then the plate support 1 is arranged on the subsurface together with the anchor parts 14 located on it. After the viscous adhesive has been applied to the bearing areas 2 of the plate support 1 and the floor panels have been placed on the plate support 1, the clamping part 16 can be screwed from above onto the threaded bolt 21 of the respective anchor leg 13.

If two adjacent floor panels are not yet flush in the same plane, the clamping part 16 will initially come into contact with the floor panel that is higher as it continues to be screwed onto the anchor part 13. A further screwing movement of the clamping part 16 then leads to the higher floor plate being pressed further downwards and the still liquid adhesive below it in the associated bearing area 2 being displaced further into the surrounding space 7 and the dimple cavities 5. This process continues until the clamping part 16 also comes into contact with the initially lower floor plate by further screwing. The leveling process between the two adjacent floor plates is then complete.

The Fig.6 The anchor foot of the anchor part 14, which cannot be seen, ensures that the anchor leg 13 is not pulled upwards out of the through hole 12 when the clamping part 16 is screwed downwards onto the floor panels. The anchor foot rests positively on the underside of the panel support 1.

After completion of the leveling process, the clamping part 16 of the leveling tool 15 can be screwed further down against the leveled floor slabs. In doing so, the anchor leg 13 is fixed to the clamping part 16 in Fig.6 The upward tensile force is so great that the anchor leg 13 breaks or tears off the anchor foot along a predetermined breaking point provided at its lower end. The anchor leg 13 and the tensioning part 16 can then be removed from the floor panels, while the anchor foot remains invisible beneath the floor covering made of the floor panels.
