Description

[0001] The invention relates to a slab support for floating stone slabs for forming a terrace surface, according to the preamble of claim 1.

[0002] Terraces are constructed to create walkable surfaces. Typically, the terrace surfaces are raised from the ground and supported on pedestals. The pedestals are usually height-adjustable to compensate for uneven ground. A grid is created on the pedestals using substructure strips and adaptable slab supports, allowing for the orderly installation of the stone slabs. The slab supports carry spacers to allow the stone slabs to be laid at regular intervals. Despite their stability, the terrace surface is subject to movement. This dynamic movement often leads to a deterioration in the surface's visual appearance.

[0003] FR 2 568 614 A1 discloses a slab support with a base that can be adapted to a substructure. The support has a cantilever to create an extended support surface. The base is connected directly to the substructure. After that, no further adjustments are possible. However, especially when installed in a composite structure, walking surfaces require appropriate adjustment options, as otherwise tensions can arise under the installed elements.

[0004] Accordingly, it is an object of the present invention to stabilize the plate storage.

[0005] This object is achieved according to the invention by a plate support having the features of claim 1. Further features of the invention are described in the dependent claims.

[0006] According to the invention, a slab support for floating stone slabs for forming a terrace walking surface is proposed, with a base which can be adapted with elements of a substructure and with a bearing plate for receiving at least one stone slab.

[0007] The bearing plate has a lateral arm with a stop arranged at the end.

[0008] The stop limits the horizontal movement of the stone slabs. While this intentionally does not adversely affect the dynamics of the installation, it does control the movement of the walking surface. The provided extension allows the stone slab to extend beyond the edge of the substructure, allowing it to be concealed for aesthetic reasons.

[0009] Furthermore, the cantilever is designed to have a support surface that complements the support surface of the bearing plate. This ensures that the stone slabs to be laid are supported without any step, as the support surfaces of the slab support and the cantilever together form a continuous and homogeneous plane.

[0010] It is preferred that the stop on the boom extends orthogonally and vertically from the support surface of the boom. This creates a parallel and thus fully effective limit in the horizontal direction of movement relative to the stone slab edges.

[0011] In a particularly advantageous embodiment of the invention, at least one mounting opening is arranged in the center of the bearing plate. Once the bearing plate is positioned, it can be mechanically fixed to the substructure, thus limiting the horizontal movement of the stone slab resting on it.

[0012] In a particularly advantageous embodiment of the invention, the boom is supported by at least one bracket. This protects the boom from buckling when loaded with a stone slab and additional foot traffic.

[0013] The invention provides for the base to be designed as a carriage that can be moved within a base rail. The dimensions between the base and the base rail are selected to ensure linear movement of the bearing plate with only minimal lateral clearance relative to the base rail.

[0014] In addition, a preferred embodiment of the invention provides for a groove-like gap between the base and the front edge of the bracket supporting the boom, which is closest to the base. This allows the edge of the base strip to be enclosed in a skid-like manner between the base and the bracket, providing additional guidance for the carriage-like movement of the bearing plate.

[0015] The invention provides that the base is formed from a square frame with raised projections on the outer surface of its frame-forming strips. While the frame can be inserted into a longitudinal opening in a base strip located in the apex area, the projections engage under parts of this base strip.

[0016] To allow the bearing plate to be pressed into such a base strip from above, the strips forming the frame base have a spring-elastic property. When the base is pressed into the base strip, they are initially displaced and then spring back to their original position, gripping the edges of the base strip. Alternatively, the cams themselves can also have a spring-elastic property.

[0017] Preferably, a substructure strip is used for adapting the slab support to form a substructure for terrace walking surfaces, which is characterized in that the substructure strip comprises means for adapting at least one slab support to the rail and means for adapting the rail to at least one pedestal support, wherein the adaptation means are lugs or pockets that can be engaged behind cams and / or hooks, and furthermore the substructure strip has means for forming a stiffened rail assembly. The means for this rail assembly are, on the one hand, beds embedded in both lateral flanks of the substructure strip and, on the other hand, a corner connector by means of which a further substructure strip in the form of a cross connector can be fastened orthogonally to the first substructure strip. The corner connector is received countersunk in the beds.The depth of each bed corresponds to the material thickness of the corner connector, so that the transversely connected substructure rail rests flush with its end face on the protruding side surface of the adjacent substructure rail. This allows the user to create a substructure with reliable transverse bracing in just a few simple steps. A particular advantage is that the rail connection allows for the creation of cassette panels, which can be used to accommodate stone slabs to weight down the substructure, for example, if the running surface is made of wood-based materials.

[0018] Preferably, an aluminum rail is used to form a substructure for terrace walking surfaces, with means for adapting at least one slab support to the rail and with means for adapting the rail to at least one pedestal support, in which the adaptation means are noses or pockets which can be engaged behind by cams and / or hooks of the slab and pedestal supports and furthermore the aluminum rail has means for forming a stiffened rail assembly.

There are various possibilities for advantageously embodying and developing the teachings of the present invention. Reference is made, on the one hand, to the subordinate claims and, on the other hand, to the following explanation of an embodiment of the invention with reference to the drawings.

[0021] The Fig. 1 to 5 show the slab support 10 according to the invention from different directions and perspectives. The slab support 10 comprises a bearing plate 14 and a base 12. A lateral outrigger 16 with an end stop 18 is arranged on the bearing plate 14, which rises orthogonally upwards from the outrigger 16 or its support surface 17. The support surface 17 of the outrigger 16 forms an extension of the support surface 15 of the bearing plate 14, so that a relatively large and flat overall support surface is present. The raised webs 19 serve to form joints between two adjacent stone slabs, which are not shown here. In the center of the bearing plate 14, a mounting opening 21 is provided, through which a screw (not shown here) can be screwed into the underlying substructure in order to fix the position of the slab support 10.The mounting opening 21 is penetrated by diagonally extending struts 23, which are part of the support surface 14 and are formed by the support surface 14 being penetrated by four rectangular openings 24 and four triangular openings 25, each of which is distributed radially around the mounting opening 21 in the center and whose corners are at least partially rounded. On the underside of the diagonally extending struts 23, these are reinforced by webs 26. The webs 26 extend diagonally from a grommet 27 located in the center and surrounding the mounting opening 21 toward the plate edge and, with their front edges, lead into a square frame of strips 13 that form the base 12. The strips 13 of the base 12 extend below the rectangular openings 24 of the bearing plate 14 and have raised cams 28 on their outer surfaces.Since the strips 13 are only connected to the bearing plate 14 in the area of ​​the base corners 29 and protrude freely in between, they have a relatively generous bending elasticity, which allows the plate support 10 to be pressed into the substructure strip from above. The strips 13 of the base 12 are pushed towards the center of the bearing plate and, due to their inherent rigidity, spring back into their original position after the base 12 has been immersed with its cams 28 in a running bed of the substructure strip, which in connection with the . Fig. 6 and Fig. 7. This snap-in action is assisted by the fact that the cams 28 have an inclined sliding surface 30, the root 31 of which is located in the strip 13. The outer dimensions of the base 12 approximately correspond to the clear dimension of the opening of the running bed of the substructure strip. The tip dimension of two opposing cams 28 exceeds this clear dimension.

[0022] The boom 16 is supported by two parallel brackets 34 extending beneath it. A groove-shaped gap 36 is formed between the end face 35 of the bracket 34 closest to the base 12.

[0023] The base 12 thus acquires the overall characteristics of a slide that can be locked in the base rail against vertically directed withdrawal forces and, at the same time, can be moved longitudinally axially within the base rail. The base rail has a corresponding geometric design and is Fig. 6 and Fig. 7 described in more detail.

[0024] The raised webs 19 are arranged in the area of ​​openings 32 in the bearing plate 14 and have a slot-shaped geometry. The connection of the webs 19 to the base plate 14 is formed by thin pins 33, which are preferably formed during the injection molding process during the manufacture of the component. The advantage of this is that the webs can be removed relatively easily when they are not needed to form a joint between two stone slabs.

[0025] The Fig. 6 and Fig. 7 shows the base rail 40 and how the plate support 10 is adapted thereto. The base rail 40 is preferably made of aluminum or an aluminum alloy. Essentially, the base rail comprises two U-shaped sections 41, 42 with a common central web 43. The rail width is limited by two flanges 44 of the upper U-shaped section 41, between which a running bed 46 is enclosed. Pockets 49 running parallel to the flanges 44 are formed by longitudinal webs 47 on both sides, which are each formed on the flanges 44 and point in the direction of the centrally extending rail longitudinal axis. The running bed 46 thus has an opening 51 with a clear dimension "I iThis is shown in the marginal figure 6a. The lower U-shaped section 42 of the base rail 40 has a smaller external dimension than the upper section 41. Its flanges 52, together with crosspieces 56 formed on the flanges, enclose a chamber 55 formed towards the floor with an opening 54. The crosspieces 56 project on both sides of the flanges 52, so that a nose 58 also remains on the outside of the rail. The flange outer wall 61 of the upper section 41 and the end face 62 of the nose 58 on the lower section 42 form a common alignment and thus the outside dimension of the rail. Due to the flange 52 being slightly set back compared to this external dimension, a bed 60 is formed in the rail flanks. This is a useful means of forming a stiffened rail assembly, which will be explained in connection with the explanations of the Fig. 14 and Fig. 15 will be discussed in more detail.

[0026] Both in the situation according to Fig. 6, in which the bracket 16 of the slab support 10 is aligned transversely to the substructure bar 40, as well as in a position of the slab support with the bracket aligned parallel to the substructure bar, an adaptation of both components is possible. The base 12 has an external dimension "b a “ which is approximately the clear dimension “l i " corresponds to the strip opening 51. The panel support 10 can thus be pressed vertically downwards with its base 12 into the running bed 46, whereby the cams 28 on the strips 13 of the base 12 are displaced towards the panel center. Once the cams 28 have passed the longitudinal webs 47 of the substructure strip, they spring back to their original position and engage underneath them. This prevents the panel support 10 from being accidentally pulled off the substructure strip 40. The tip dimension "b s “ of two opposite cams 28, which is larger than the clear dimension “l iHowever, it has a smaller extension than the width of the running bed 46, so that the panel support 10 can be freely moved in the longitudinal direction of the strip. This is supported by a groove-shaped gap 36 formed between the end face 35 of the bracket 34 supporting the boom, which is closest to the base 12. The flange 44 of the substructure strip 40 with its strip 47 is located in this gap. Once the desired end position of the panel support has been determined, the panel position on the substructure strip can be fixed by means of a screw screwed into the mounting opening.

[0027] The Fig. Figures 8-13 show a slab support 10a that is not installed at the edge, but rather across the entire surface. The structure of this slab support 10a is identical to slab support 10, with the exception of the missing outrigger. Furthermore, four upright slats 13 are provided to form a joint cross.

[0028] The Fig. 14-18 show the structure of a terrace whose walking surface is formed by stone slabs 70. Once the area to be spanned by the walking surface has been determined, the pedestals 80 are distributed over it. The pedestals 80 are height-adjustable so that a level surface, if necessary with a defined gradient, can be created. The substructure strips 40 are mounted on the pedestals 80 in a specific grid, which is determined taking into account the geometry of the walking surface elements. It is particularly important here that the substructure has a certain rigidity in order to counteract both longitudinal and transverse forces. For this purpose, cross connectors 40a must be inserted into the parallel substructure strips. These consist of the same strip material, i.e., an identical cross-sectional profile.In order to fasten a cross connector 40a aligned at right angles to a substructure strip 40 to the substructure strip 40, a corner connector 65 (see . Fig. 6) is used, which is designed in the form of an angle. The leg height is selected so that the leg fits into the bed 60 in the strip flanks of the substructure strip 40 or the cross connector 40a, whereby the leg thickness "s" corresponds to the depth "t" of the bed. This provides guidance for the corner connector, which allows one-handed assembly. Compared to conventional connections, the design selected here has the advantage that the cross connector sits flush with its end face on the flank of the adjacent substructure strip, dramatically increasing the degree of stiffening. In addition, closed cassettes can be formed, which is particularly advantageous when different types of running surfaces are combined, which is possible for the first time with the present invention. There are practically no limits to the designer. The possibilities are open to them, for exampleCombining a wood-based walking surface in the form of planks or slabs with stone slabs without creating any ledges. In any case, a closed walking surface can be created. The cassette design also makes it possible to use stone slabs for weighting on a wooden terrace.

[0029] As the Fig. As shown in Figures 14-18, the plate supports 10a are used in the surface, while the plate supports 10 with lateral outriggers are used in the edge area.
