Definitions
- the present invention relates to a floor covering disposed on a substrate and comprising a layer or course of particulate material and means for at least partly filling out the interspaces between the individual pieces of particulate material, the particulate material and filler material being surface-ground so that both are exposed in the free surface of the floor.
- a floor covering of approximately the above-outlined type is previously known from CH 361 114.
- This floor covering is applied on a porous concrete floor which has been waterproofed and insulated with a number of insulating layers. Above these layers, there is disposed a covering layer which is substantially based on a plastic binder. Further, particles are worked into the covering layer, whereafter, after complete curing, the upper surface of the floor covering is surface-ground.
- a floor of this type may, in certain cases, function well but does not display a higher level of load bearing capacity and resistance to point loadings than is permitted by the actual plastic material in the covering layer. Furthermore, and this is most important, the costs of producing such a floor are so high that such a floor can hardly be put into practical use other than in exceptional cases.
- the present invention has for its object to design the floor covering described by way of introduction such that the drawbacks inherent in the prior art methods and technology are obviated.
- the present invention has for its object to realise a floor covering which has improved load bearing capacity, against extensive, dynamic and point loadings.
- the present invention has for its object to realise a floor covering which may be manufactured at a highly competitive price and, in addition, a floor covering whose appearance may be varied within broad limits.
- the floor covering disclosed by way of introduction is characterized in that the filler includes a lower layer substantially consisting of plastic-based bonding material for anchoring the individual pieces of particulate material in the substrate, and an upper layer substantially consisting of inorganic material for realising a compact floor surface.
- the floor covering rests on a substrate 1.
- the substrate may, for example, be an extant concrete floor but can, according to the present invention, be of any optional nature.
- the floor covering includes a layer 2 of substantially plastic-based bonding material which is employed for anchoring pieces 3 of a particulate material in the substrate 1.
- the floor covering includes an upper layer 4 substantially consisting of inorganic material for realising a compact surface on the floor covering.
- both the pieces 3 of particulate material and the upper layer 4 form an upper and uneven defining surface of the floor covering.
- both the pieces 3 of particulate material and the exposed portions of the upper layer 4 are surface-ground to smoothness so that the floor covering displays the upper, planar surface 5 as shown in Fig. 2.
- the upper surface of the floor covering can suitably be protective-painted with a two can coating.
- the lower layer 2 of bonding compound has, in the illustrated embodiment, a thickness of from one or a few tenths of a millimetre up to a couple or three millimetres, suitably of the order of magnitude of 1-2 mm.
- the bonding material can be applied in such a manner that it forms bridges between the individual pieces 3 of particulate material. For example, this may be achieved in that a slightly thicker layer of bonding material is applied, whereafter the particulate material is spread out and "stirred about" in the as yet uncured bonding material so that the above-mentioned bridges or bond unions between the pieces are formed.
- Another variation for realising such bridges or bonds between the individual pieces 3 could be to pre-treat them with bonding material before they are spread and levelled out over the substrate 1.
- a bonding material which has proved to function very well in practice is an epoxy resin which is manufactured by Perstorp Bygghartser and is sold under the brand name Peran Rustik.

Abstract
Description
- The present invention relates to a floor covering disposed on a substrate and comprising a layer or course of particulate material and means for at least partly filling out the interspaces between the individual pieces of particulate material, the particulate material and filler material being surface-ground so that both are exposed in the free surface of the floor.
- A floor covering of approximately the above-outlined type is previously known from CH 361 114. This floor covering is applied on a porous concrete floor which has been waterproofed and insulated with a number of insulating layers. Above these layers, there is disposed a covering layer which is substantially based on a plastic binder. Further, particles are worked into the covering layer, whereafter, after complete curing, the upper surface of the floor covering is surface-ground.
- A floor of this type may, in certain cases, function well but does not display a higher level of load bearing capacity and resistance to point loadings than is permitted by the actual plastic material in the covering layer. Furthermore, and this is most important, the costs of producing such a floor are so high that such a floor can hardly be put into practical use other than in exceptional cases.
- A similar structure is also described in
DE 1 509 879. - The present invention has for its object to design the floor covering described by way of introduction such that the drawbacks inherent in the prior art methods and technology are obviated. In particular, the present invention has for its object to realise a floor covering which has improved load bearing capacity, against extensive, dynamic and point loadings. Further, the present invention has for its object to realise a floor covering which may be manufactured at a highly competitive price and, in addition, a floor covering whose appearance may be varied within broad limits.
- The objects forming the basis of the present invention will be attained if the floor covering disclosed by way of introduction is characterized in that the filler includes a lower layer substantially consisting of plastic-based bonding material for anchoring the individual pieces of particulate material in the substrate, and an upper layer substantially consisting of inorganic material for realising a compact floor surface.
- Further advantages will be attained according to the present invention if the floor covering is also given one or more of the characterizing features as set forth in appended
subclaims 2 to 6. - The present invention will now be described in greater detail hereinbelow with reference to the accompanying Drawing, in which:
- Fig. 1
- is a cross section through a partly ready-laid floor; and
- Fig. 2
- shows the same floor after completion.
- From the Figures, which show a cross section through a floor covering according to the present invention, it is apparent that the floor covering rests on a
substrate 1. The substrate may, for example, be an extant concrete floor but can, according to the present invention, be of any optional nature. Above thesubstrate 1, the floor covering includes alayer 2 of substantially plastic-based bonding material which is employed for anchoringpieces 3 of a particulate material in thesubstrate 1. Further, the floor covering includes anupper layer 4 substantially consisting of inorganic material for realising a compact surface on the floor covering. - In Fig. 1, the floor covering is shown as it appears after the application of the above-considered layers. It will be apparent from the Figure that both the
pieces 3 of particulate material and theupper layer 4 form an upper and uneven defining surface of the floor covering. In order to achieve a final and aesthetically appealing appearance, both thepieces 3 of particulate material and the exposed portions of theupper layer 4 are surface-ground to smoothness so that the floor covering displays the upper,planar surface 5 as shown in Fig. 2. After the surface grinding operation, the upper surface of the floor covering can suitably be protective-painted with a two can coating. - The
lower layer 2 of bonding compound has, in the illustrated embodiment, a thickness of from one or a few tenths of a millimetre up to a couple or three millimetres, suitably of the order of magnitude of 1-2 mm. In order to form a floor covering with greater mechanical strength, it is an advantage if the bonding material can be applied in such a manner that it forms bridges between theindividual pieces 3 of particulate material. For example, this may be achieved in that a slightly thicker layer of bonding material is applied, whereafter the particulate material is spread out and "stirred about" in the as yet uncured bonding material so that the above-mentioned bridges or bond unions between the pieces are formed. Another variation for realising such bridges or bonds between theindividual pieces 3 could be to pre-treat them with bonding material before they are spread and levelled out over thesubstrate 1. - Depending on the quality and cleanness of the
substrate 1, it may possibly be necessary to use a primer to improve bonding of the bondingmaterial 2 to thesubstrate 1. - A bonding material which has proved to function very well in practice is an epoxy resin which is manufactured by Perstorp Bygghartser and is sold under the brand name Peran Rustik.
- It will further be apparent from the Figures that there may be - or are -
air pockets 6 between theindividual pieces 3 of particulate material and different free surfaces of theupper layer 4. If the quantity of such air pockets is increased, the bearing capacity of the floor will naturally be reduced, at the same time as the costs of producing the floor are reduced. The quantity of material which is employed in the upper layer may be regulated in such a manner, and also the penetration of the material between theindividual pieces 3 of particulate material, that the final result will be a floor which is adapted to the requirements applicable at the time. The crucial factor is only that theupper layer 4 is made homogeneous and fully covering within the region which is to be ground down to theplanar surface 5 and the region just beneath it. - In one embodiment in which the majority of the
individual pieces 3 of particulate material are interconnected to one another via bridges or bonds of bondingmaterial 2, the particulate material forms a three-dimensional lattice structure which in itself displays extremely high load bearing capacity. In this embodiment, the number ofair pockets 6 may be considerably greater than is shown in the Figures. - The
upper layer 4 is a substantially cement-based filler or compound with inorganic aggregate material. By way of example of a commercially available preparation which has proved to be advantageous in this context, mention might be made of a screeding compound which is sold under the designation UZIN-NC 170. - As regards the
particulate material 3, this may consist of a masonry material of different qualities, marble, crushed ceramics, etc. The particle size need not be calibrated, but should lie in the order of magnitude of 1-15 mm. However, the particle size preferably lies in the mixed range of 3-10 mm. Further, the individual pieces are irregular in configuration and thereby afford good adhesion both to the bondingmaterial 2 and to the screeding compound which is employed in theupper layer 4. - The protective painting or top painting which is carried out on the
planar surface 5 may suitably be put into effect employing a water-based two can paint which is marketed under the commercial brand name NM Topplack 92 Express. - The present invention may be modified without departing from the scope of the appended Claims.
