Definitions

  • the present invention relates to a subfloor or covering floor for a flooring or flooring elements consisting of an assembly comprising at least a lower plate and a top plate, in which the plates are, or have been, glued to one another, or otherwise.
  • Such assembled subfloors are known per se and serve for levelling the substrate on which they are applied on one hand, and for achieving a sufficiently high sound insulation on the other, which mainly concerns muffling of impact sound.
  • these subfloors are used together with regular floor covering and even with parquet, on can achieve conclusive results to remain within the old standards in relation to impact sound in house-construction.
  • the object of the invention is to provide a subfloor by which said impact sound reduction can be realized.
  • a further object is to provide a subfloor which is suitable for all types of flooring and which can realize the impact sound reduction when combined with said flooring as well.
  • Said floorings include floorings which are difficult to apply such as ceramic floor elements or floor elements of natural stone.
  • the assembly is designed in such a way that an impact sound reduction of at least 10 dB, according to NEN-ISO 140-8/717-2 ( ⁇ L lin ) is realized and that the assembly is suitable for mounting all types of flooring on it including ceramic flooring elements or flooring elements of natural stone.
  • the upper plate is manufactured from a foam material with a reinforcing layer of glass fibre being applied on at least one side thereof.
  • the foam material is e.g. an extruded foam material, such as hard polystyrene, for example
  • a top plate which - from a certain thickness - has sufficiently sound-insulating properties for fulfilling the stated standard combined with a subfloor plate.
  • this top plate is stiff enough to form a plane supporting base for all types of flooring and is at the same time strong enough to be able to carry the heaviest coverings, ceramic or natural stone floor elements in particular.
  • a completely plane floor with ceramic or natural stone floor elements or floor elements of natural stone can be realized.
  • the reinforcing layer of glass fibre further provides a proper plane of adhesion for fitting any type of desired flooring including ceramic or natural stone floor elements onto said top plate.
  • the glass fibre is provided with a layer of cement-bonded gratisine on the top side of the plate.
  • top plates can be properly connected to one another along their abutting edges.
  • a fabric tape is provided which in longitudinal direction across the lines of contact or joints will be applied between abutting top plates.
  • this a self-adhesive glass fibre tape that can be applied in one operational run.
  • the lower plate is preferably assembled from another material than the top plate in which the transition between the various arrangements contributes to the suppression of impact sound.
  • the lower plate substantially comprises a resilient wood fibre board.
  • the top plate comprises a cement-bonded fibre board.
  • a top plate has the advantage that it presents a structurally extremely stiff subfloor having a large load bearing capacity.
  • Such a subfloor is particularly suitable for fitting ceramic or natural stone floor elements on it.
  • lower plate likewise at least one plate of another material is employed such as a plate of wood fibre material, preferably a plate having resilient properties such as soft board, for example.
  • a plate of wood fibre material preferably a plate having resilient properties such as soft board, for example.
  • the big difference in specific density of such a lower plate in comparison with a cement-bonded top plate contributes to the fact that very good sound insulating properties can be realized with the assembly of this lower and top plate.
  • the sound insulating properties can be improved further by applying a layer composed of a latex-bonded mixture of coconut and wood fibres onto the top plate.
  • this further layer is fixedly connected to the top plate.
  • the further layer is applied onto the top plate with glue, which glue is used simultaneously or consecutively for applying the flooring.
  • the lower plate in this embodiment likewise comprises a resilient wood fibre board.
  • the lower plate consists of a first and a second soft and/of resilient wood fibre board, in which the first wood fibre board, the lower wood fibre board, is intended for receiving piping systems.
  • the subfloor will have a larger thickness and is therefore intended especially for being employed as covering floor in houses under construction, in which the thickness of the covering floor has been taken into account in advance.
  • Ducts for lines such as e.g. power cables, water pipes and heating pipes, can be milled in the first wood fibre board.
  • said first wood fibre board, the lower wood fibre board consists of various dimensioned parts, in such a way that consecutive dimensioned parts together can form a continuous piping slot.
  • the top plates are provided with a groove and tongue system for mutual engagement of the subsequent parts of the subfloor.
  • the covering floor can be laid quickly, in which a proper connection of the plates is guaranteed. The latter is important for both forming a plane, stiff floor and for the sound insulating properties.
  • the lower and top plates can be intimately connected to one another. This can be realized effectively by mutually glueing the plates.
  • a glue component is applied to the bottom side of the top plate, which glue component is intended to establish a glue connection with a complementary glue component applied to the top side of the lower plate.
  • the lower plate is provided with a paper layer, namely a paper layer having the important property of engaging a fibre structure particularly well.
  • the glue components have the property that they mutually provide for a particularly well adhesion but that they will not, or only hardly, adhere to other surfaces.
  • a subfloor system is achieved which can be processed easily and in which an excellent mutual adherence between the plates can be established.
  • a two component mortar is provided, the first component comprising a synthetic resin and the second one a cement.
  • the first component is a dispersion of a synthetic resin and a rubber granulate and the second component is a cement, more preferably a quick cement.
  • Such a composition yields a mortar having permanent elastic properties, which furthermore adheres particularly well to the cement-bonded ceremoniine layer applied on the glass fibre reinforcement layer on the top plate.
  • Use of the quick cement provides for a quick setting as a result of which a laid floor can be walked on after a relatively short time.
  • joint mortar which is preferably a two component mortar, the first component substantially comprising a cement and the second component being a dispersion having elastic properties.
  • Said joint mortar has greater elastic properties than the mortar for applying the floor elements as a result of which the joints are capable of, if necessary, absorbing any movement between adjacent floor elements.
  • Fig. 1 shows an assembly 1 of lower plates 2 and top plates 3 applied floatingly on a supporting floor 4.
  • the plates have been laid in offset relationship in such a way that subsequent connections between plates are not aligned on any location and the connections between lower and top plates do not coincide on any location.
  • Ceramic or natural stone floor elements 5 have been fitted on the top plates, in which one tries, as far as possible, to have the joints between floor elements not coincide with the connections between top plates 3.
  • Fig. 2 shows a cross-section of an assembly of lower plates 2 en top plates 3, with ceramic or natural stone floor elements 5 being mounted on top plates 3.
  • the lower plate 2 a soft wood fibre plate (softboard), is floatingly mounted on the supporting floor 4 and is intended for correction of irregularities in that floor, as well as for reduction of sound, impact sound in particular.
  • Lower plate 2 and top plate 3 are glued to one another, to which end a special adhesive layer 6, 7 has been applied on the sides concerned of said plates, which has been done with a roller or in a more automated process with a roll.
  • the adhesive of these identical adhesive layers 6, 7 has such properties that mutual contact will yield a particularly well glueing connection, but that in case of contact with other surfaces there will be no or hardly any adhesive force.
  • a paper layer 8 is applied on said lower plate 2, which is preferably composed of a resilient fibre material.
  • Top layer 3 comprises substantially a foam material, which is preferably an extruded hard polystyrene, which is particularly suitable for supporting the ceramic or natural stone floor elements 5.
  • a reinforcing layer 9, 10 is applied on both sides, preferably comprising a glass fibre layer.
  • glass fibre strips 11 have been applied across the joints between the adjacent top plates.
  • self-adhesive glass fibre strips 11 are applied.
  • a mortar layer 12 having somewhat resilient characteristics is applied on the mutually connected top plates 3, through which layer the ceramic or natural stone floor elements 5 are fixedly connected to the subfloor.
  • a special joint mortar 13 which is likewise slightly resilient, but which need not have the specific properties of said mortar 12.
  • Fig. 3 shows an example of the second embodiment in which the polystyrene plate has been substituted by a cement-bonded wood fibre board 14, a cement-bonded chipboard, for example.
  • the same reference numbers have been used for the further constituent parts corresponding to those in the example of fig. 1.
  • the wood fibre board 14 has a much higher specific density than the lower layer 2. Also due to the strongly differing properties, this assembly provides for a very effective sound reduction and is furthermore particularly suitable for supporting the heaviest floorings, including ceramic or natural stone floor elements.
  • Fig. 4 shows a further variation in which a further plate 17 of a soft and/or resilient fibre material, e.g. softboard, has been applied underneath said assembly of fibre board 2 and cement-bonded wood fibre board 14.
  • the plates 2 and 14 are preferably glued to one another in advance, and further a groove 19 and tongue 18 system has been provided by which the consecutive assembled plates 2, 14 can engage one another. Further finishing is similar to the finishing shown in fig. 3, by way of example.
  • Further plate 17 is provided with slots 20, which can be made by milling them from plate 17 or by spacing certain plates 17 so that a continous slot arises between them. It is also possible to provide a certain part of the plates 17 with a slot beforehand or the plates 17 can be supplied in various dimensions.
  • the slots are made in such a way, that continuous slots are always at a predetermined distance from a wall.
  • the slots 20 are intended for receiving pipes 21, 22 such as e.g. water pipes, ducts of a heating system, electricity wires and the like.
  • the measurements were carried out with slots having a length of 2 metres per square metre of floor surface, with pipes mounted in the slots.
  • this subfloor With a thus assembled subfloor a particularly large sound reduction can be realized through which also possible future standards can be met. Furthermore this subfloor is suitable for all types of floorings, thus also for heavy coverings with ceramic or natural stone floor elements. Due to the total thickness of the subfloor it is particularly suitable for being employed in houses under construction, where this thickness has already been taken into account. The possibility of incorporating pipe systems in the subfloor allows for that a specific part of the construction work can be carried out much more efficiently. Furthermore, this construction method produces a much more clearly structured piping system.
