Abstract

1. A method of manufacturing self-supporting slabs for laying as floor slabs and/or footpath slabs in house building and horticulture, comprising a slab of natural stone mounted on a mouldable, hardening material such as cement with an adhesive layer interposed therebetween, characterised in that stones are split into layers and are cut to size to form polygonal slabs (1), that an inherently hardening adhesive (2) is applied to one of the two unfinished surfaces of the slab of natural stone, that a layer (3) of cement determining the thickness of the slab is applied to the fresh, unhardened layer of adhesive (2), and that the cement and the adhesive are then age-hardened.

Self-supporting plate

The present invention relates to a self-supporting plate according to the generic term of the independent Claim 1.

Slabs for covering ground and / or sidewalks made of natural stone have been used in particular until today pressure-resistant rocks, such as granite or gneiss strata or special marls and limestones, which are also available in corresponding, self-supporting layer thickness are limited.

Brittle materials or thinly layered materials such as slate, but also lime and porphyry, could not be used as self-supporting panels for flooring. It was a specially prepared one

Underlay necessary, also for cases in which a self-supporting panel can be used without an additional base layer were.

For laying outdoors on the ground or on sand, stones of various thicknesses could also be used Find. However, in buildings and on concrete surfaces, either the plates had to be read out or the split plates had to be ground to a given thickness, which is because of the additional Machining is very expensive.

It is the object of the invention to propose a novel plate with which the spectrum which can enlarge usable rocks and become one comparable price with the concrete slabs made of exposed aggregate concrete can be brought on the market.

According to the invention, this is achieved by the features of patent claims and the subclaims.

Embodiments of the invention are described below. In the drawing show:

FIG. 2 shows a detail from a cross section through the plate according to FIG. 1 on an enlarged scale.

A rock slab 1 made of e.g. Penhill slate, Berdal quartzite, Kotah limestone, Bidar slate or Porphyry, which arises with an insufficient thickness, is processed on their outline edges that a polygon with straight edge lines are created. The panels are preferably cut rectangular. On the one polygonal surface a covering layer 2 of a two-component adhesive is painted and immediately afterwards, i.e. fresh on fresh, a concrete layer 3 is applied to the adhesive layer.

This concrete layer is preferably made of a concrete with a maximum grain size of 0 to 30 mm and a quality of 300 kg Portland cement per m concrete.

If the stone slab does not have plane-parallel surfaces, the concrete can make the required Parallelism can be established between the two surfaces.

As a floor covering in houses, the concrete layer can be provided with through openings, into which pipes for the line of a heat transport medium can be inserted,

or pipe sections could be poured in directly that carry transition plug-in sleeves on one side in order to connect with pipes to allow a tight connection to an adjacent plate.

Slabs can be made using a stable concrete with a carefully composed grain structure Manufacture with a thickness that is suitable for the respective purpose and without further measures e.g. can be laid in a sand bed.

summary

The rock plate consists of a layer of rock O), adhesive (2) a two-component adhesive and a load-bearing concrete layer (3). In this way, rocks can be used for flooring, which could otherwise only be used with the use of special underlay floors and therefore work accordingly and inconvenience to relocate.
