Description

[0001] The invention relates to a building element for forming a floor covering, in particular in an outdoor area, with a rectangular covering plate made of stoneware, glass or metal and a frame-like formation made of a plastic material around the edge of the plate.

[0002] To create outdoor flooring, stoneware slabs, such as concrete or natural stone, are laid in a bed of sand and / or gravel. By penetrating the joints between the slabs during embedding, the slabs are largely protected against horizontal displacement.

[0003] DE 10 2013 224 478 A1, WO 2013 / 000456 A1, WO 2007 / 144244 A2 and DE 10 2013 106 302 A1 disclose building elements of the type mentioned above, the covering plate of which is connected directly or indirectly via an intermediate layer to a substructure stabilising the building element, in particular a carrier plate.

[0004] The invention is based on the object of creating a new building element of the type mentioned at the outset, by means of which the formation of floor coverings is facilitated with increased covering quality.

[0005] The component according to the invention which achieves this object is characterized in that the surface of the underside of the covering plate which is framed by the formation is free of formations or is free of formations except for one or more sprue strands and / or webs which project inwards from the frame-like circumferential formation.

[0006] The inventive overmold made of plastic material allows for a very uniform, aesthetically pleasing joint pattern to be easily created during installation of the building elements by creating joints between the overmolds. By concentrating the overmolds on the edge of the paving slab, the frame-like overmold can penetrate more easily into the bed when the building elements are installed in a bed of sand and / or gravel, providing the paving with stable horizontal support.

[0007] In a particularly preferred embodiment of the invention, the frame-like circumferential molding is injection-molded and / or foamed onto the covering plate while arranging the covering plate in a mold cavity.

[0008] In a particularly preferred embodiment, the covering plate is made of porcelain stoneware.

[0009] The shaping advantageously includes a covering section that covers the edge surfaces of the slabs all around to form a half joint filling.

[0010] While the molding in the covering composite between the building elements could only form a joint, in particular between the covering sections, the molding preferably has devices for the edge-side connection of such building elements forming the floor covering to one another.

[0011] In particular, the molding comprises a section projecting downwards beyond the underside of the covering plate, wherein the above-mentioned connecting devices are preferably formed by this section of the molding.

[0012] The connecting devices advantageously comprise elements for plugging in vertical or horizontal plugging direction.

[0013] In a particularly preferred embodiment of the invention, the portion of the molding projecting beyond the underside of the covering plate has a connecting strip with plug holes on two mutually perpendicular edges of the covering plate, and plug pins arranged beneath the covering plate on the two remaining edges of the covering plate. The plug holes and plug pins could also be interchanged.

[0014] The portion projecting beyond the underside of the covering plate preferably has a projecting length of 5 to 10 mm, in particular 8 mm.

[0015] The thickness of the covering plate is preferably > 10 mm, in particular ≥ 20 mm.

[0016] The invention is further explained below with reference to exemplary embodiments and the accompanying drawings relating to these exemplary embodiments. They show: Fig. 1 shows a component according to the invention in a plan view, Fig. 2 shows the component according to the invention from Fig. 1 in a sectional side view, Fig. 3 the component of Fig. 1 in a partial view from below, and Fig. 4 a second embodiment of a component according to the invention in a partial view from below, and Figs. 5 to 7 a third embodiment of a component according to the invention in different views.

[0017] One in Fig. 1 A plan view of the building element for forming a floor covering, e.g., in an outdoor area exposed to the weather, comprises a covering slab 1, which in the example shown is made of porcelain stoneware and has a thickness of 20 mm. The edge length of the square covering slab is 60 cm.

[0018] The covering plate 1 is connected to a frame-like molding 2 running around the edge of the plate. This molding was injection-molded onto the covering plate 1 in a mold (not shown) and, in the example shown, is made of polyurethane (PU). During the injection-molded and foamed process, a material-to-material bond was created between the covering plate 1 and the molding 2.

[0019] As the Fig. 1 to 3 As can be seen, the frame-like circumferential formation 2 comprises a section 3 which projects downwards beyond the underside of the covering plate 1, as well as a section 4 which forms a covering surrounding the edge surface of the covering plate 1, the thickness of which corresponds to half the joint width.

[0020] While the section 4 forming the surrounding covering serves to fill the joints, the section 3 projecting downwards beyond the underside of the covering panel 1 forms devices for connecting such building elements to one another. As such devices, the section has a frame leg 10 on each of the two mutually perpendicular edges of the covering panel 1, with a connecting strip 5 projecting beyond the panel edge and a row of plug holes 6 extending in the longitudinal direction of the strip. On the two remaining mutually perpendicular edges of the covering panel 1, the downwardly projecting section 3 forms frame legs 11 with plug pins 7 corresponding to the plug holes 6.

[0021] On the edge sides of the base plate 1 having the connecting strips 5, the covering formed by the section 4 has depressions 8 and on the other edge sides it has bulges 9.

[0022] The section 3 of the molding 2, which projects beyond the underside and forms the frame legs 10 and 11 on mutually perpendicular panel sides, rests on a subfloor with a frame-like, flat underside 12 when the building element is laid.

[0023] The subfloor may be a concrete floor. In this case, the covering slab 1 maintains a distance from the subfloor, so that applied loads are transferred from the covering slab to the subfloor solely via the formation 2.

[0024] Alternatively, the subsoil can have a layer of sand and / or gravel. The structural element sinks slightly into an uncompacted upper layer of sand or gravel with the protruding section 3 of the formed portion 2 until the covering slab 1 also rests on the upper layer. Loads are thus transferred not only via the formed portion 2 but also directly from the covering slab 1 to the subsoil.

[0025] To form a floor covering, the components are vertically interlocked at the edges, with the plug pins 7 penetrating the plug holes 2, creating a force-locking connection. It is understood that a positive locking connection can also be created via the plug holes and pins. This connection between the components imparts high stability to the resulting floor covering.

[0026] When assembled, section 4 of the projection 2 of each structural element forms half of the joint filler. The fact that sections 4 of adjacent structural elements are in close contact with one another results in a uniform joint pattern. The recesses 8 and bulges 9 protect the structural elements of the decking from vertical displacement.

[0027] In the Fig. 1 to 3 In the embodiment shown, a gate (not shown) is formed directly on the frame-like formation 2. In the embodiment of Fig. 4A sprue point 13 is arranged at a distance from the frame-like formation 2. From the sprue point 13, a sprue strand 14 connected to the covering plate 1 extends to the frame part 10 having the plug holes 6 in the connecting strip 5.

[0028] Furthermore, deviating from the embodiment of Fig. 1 to 3 the formation 2 has a widening 15 in each of the corner areas, which advantageously reduces the surface pressure in the corner areas.

[0029] In the case of a Figures 5 to 7In the exemplary embodiment shown, webs 16 are further formed onto a covering plate 1 and a frame-like projection 2, which webs extend inward from opposing frame legs of the projection 2 and each end freely. The width of the webs 16, which are aligned with one another in the example in question, is significantly less than the width of the frame legs. In the example, the height of the webs 16 projecting from the covering plate 1 corresponds to the projection 2. Reference numeral 14 designates a sprue web perpendicular to the webs 16.

[0030] The webs advantageously counteract horizontal displacement of the building elements, especially on loose ground.
