flooring

Abstract

<PICT:1008123 / C3 / 1> A floor covering comprises an elastomer sheet formed on the underside thereof and integrally with the sheet with a multiplicity of closely spaced, shallow stud-like protuberances distributed substantially uniformly over the entire area of said underside, said protuberances having an end-face area which is greater than the cross-sectional area of the protuberance in the immediate neighbourhood of said underside and said protuberances being shallow in the sense that their height dimension is substantially less than their minimum width dimension. Referring to Fig. 1, the flooring material is laid by spreading cement or an adhesive over the area to be covered, then pressing the sheet (2) into the cement or adhesive to cause the cement or adhesive to fill the spaces between the studs (3) and the underside of the sheet (1). The surface of the sheet may be provided with a non-slip surface profile of any desired configuration.

Description

Re: German patent application P 15 09 Semperit Austrian-Ainerikanlsohe Gummiwerke Aktiengesellschaft in Vienna flooring The invention relates to a floor covering made of elastic material, such as rubber or the like, in the form of a slab, which is particularly suitable for Suitable for stable flooring. Such well-known floor coverings, when used in stables, serve the purpose of protecting the animals' hooves and the To provide animals with a warm and soft resting place. Such a covering completely insulates against rising damp and does not absorb any moisture itself. It absorbs moisture. Therefore, it is hygienic and germ-free and can be easily disinfected in case of barn parasites. The well-known floor coverings These types are simply placed on the ground, which has the disadvantage that they can slip and that foreign objects can also get trapped. and dirt can get under the covering tile, causing the surface to become uneven. Gluing such coverings to the floor could also prevent this. A stable connection could not be established. It has also been suggested to distribute circular patterns across the entire surface of the underside of paving slabs or similar materials in the sublayer. Protrusions are to be provided that taper conically towards the slab. Single-layer paving slabs are laid in such a way that the old protrusions are provided. Underside of the slabs coated with a cement slurry, if necessary 909846 / 0236 (Art· ? I* *** S No. ? S-tr 3 2---" -.-ici-uns··» v.4. * sand is contained, for example, a sand or cement mixture in a 1:1 ratio is sprinkled in so that the space between the sioh the tapered projections are completely filled with the cement slurry, and the slabs are then laid on a subfloor of hardened concrete. or made of stones or bricks, etc., which had been thoroughly cleaned beforehand and soaked with plenty of water or cement slurry, laid down and attached to These were pressed down. After the cement slurry has hardened, the protrusions provide an anchoring of the paving slab. In the known case In this arrangement, the distance between the projections is now kept so small that there is no longer any guarantee that the cement slurry will be contained in the area. the smallest gap between the frustoconical projections can penetrate. Therefore, cavities can form, which allows the There is a possibility that the rubber could deform laterally, as the frustoconical protrusions would then no longer be accessible from all sides. are encased in concrete. In this case, a significantly less force is required to dislodge a truncated cone-shaped projection from its anchoring. to pull out, so that after installation blister-like elevations can occur in the covering which can no longer be corrected and to render the coating unusable. Even if, in this known arrangement, the entire space between the cone-shaped If the protrusions are filled with cement slurry, the small distance between the two protrusions results in only narrow concrete ridges. which have insufficient anchoring to the subfloor and can easily tear off, which in turn can cause the covering to detach from the subfloor. The underbody can be done. The present invention seeks to avoid the disadvantages of the known floor covering and to provide a floor covering, particularly for stable floors. to create a secure anchoring to the subfloor. The invention essentially consists in the fact that the smallest The distances between the projections are approximately equal to the diameter of the projections. -2-909846 / 0236 bO9A17 This corresponds to the requirements. With such a design of the floor covering, the distance between the circular protrusions is not so small, therefore The risk exists that, as a result of inadequate filling of the space between the pre-forms with cerumen paste or insufficient Anchoring the hardened concrete to the subfloor; there is a risk of the floor slab detaching; 1st, the distance between the However, the pre-existing conditions are not so great as to restrict the anchoring to individual points that are too far apart, in which case the anchoring would be insufficient and there would be a risk of the slab lifting between the anchoring points. The inventive design of the floor covering thus ensures its secure fixation to the subfloor. According to the invention, the height of the projections can be approximately one-quarter of the thickness of the slabs. If the smallest distances between the projections are approximately equal to the diameter of these projections, this height is sufficient to achieve secure anchoring of the floor covering, and it is not necessary to provide higher projections. This saves on rubber during the manufacturing of the covering and also reduces the amount of cement mortar required for laying the covering. Furthermore, with this projection height, pressing down the slab is easily possible without the need for a press plate. Furthermore, it has proven advantageous if the undercut angle of the projections is approximately 20°. Such a The angle of undercut is large enough to secure the anchorage, and with such an undercut angle, the white cement or similar material can penetrate into the undercuts and adhere tightly to the side walls of the projections. If necessary, the substrate onto which the slab is pressed can also consist of a permanently plastic material, such as bitumen. In this case, however, lifting of the slabs is not entirely impossible due to the angle of undercutting the projections; however, anchorage is still achieved through the projections. -3-909846 / 0236 &Ggr; I0U3H I / The surface of the plate can be equipped with any type of non-slip profile. The invention is explained in the drawing using an exemplary embodiment. Fig. 1 shows a cross-section through the plate. Fig. 2 shows a bottom view, Fig. 3 shows a top view, and Fig. k shows a detail of the vulcanized layer. On the underside 1 of the plate 2, which is made of rubber, protrusions 3 are provided, which are made of one piece with the plate 2. These projections are circular in the underside view according to Fig. 2 and taper conically towards plate 2, so that a conical side surface k of this This results in protrusions. The angle of intersection is preferably about 20°. The height a of these protrusions is approximately l / k of the thickness b of the plate. 2. In a practical embodiment, the thickness b of the plate is chosen to be approximately 1 cm. The spacings Γzwłłsoł arranged in a row The projections are slightly smaller than their diameter d. The diagonal distances e between these projections are slightly larger than the diameter d of the same. On average, the distances between these protrusions correspond approximately to the diameter or width. the same. In a practical embodiment, for example, the diameter of these projections 3 can be measured at 1 cm, so that it approximately the thickness of the plate. The surface 5 of the plate is provided with a non-slip grooved design 6. The production of such a plate can be carried out in a simple manner, as Fig. k shows. A sheet 7 is used to form the protrusions. Vulcanizing mold 9 is provided, into which conical holes are drilled, and whose thickness corresponds to the height of the projections 3. These holes &thgr; are covered by a second sheet 10, which has ventilation holes 11 in the area of ​​the conical holes &bgr; of the sheet 7. The rubber material to be vulcanized penetrates these ventilation bores 11, so that small plugs form on the final product, as shown in Fig. 1 and 2 are not shown. Because sheets 7 and 10 are now detachable from each other, sheet 10 can be removed first during demolding. so that the molded, reversed -I1- 909846 / 0236 young protrusions 3 can be more easily pulled out of the Dleoh 7.
