Abstract
Description
- The invention relates to a subfloor-assembly comprising a number of layers from which one is formed by a lower part and another is formed by a top plate, which subfloor-assembly is adapted to be applied onto a supporting floor and covered with flooring elements, which can be formed by ceramic or natural stone elements.
- Such a subfloor-assembly is known by
US 5,187,905 . In case of this subfloor-assembly the lower part, indicated as the "second upper layer", is formed by an elastic foam, such as a latex foam. This second upper layer is applied onto a "first lower sub-assembly" formed by a number of layers which in particular are formed by oxidized bitumen in which glass fibers can be embedded. - So this known assembly is rather complicated and said "first lower sub-assenbly" is connected to said supporting floor by means of a layer of an adhesive bituminous binding agent. So it will be hardly possible to remove said assembly when one should want to replace this.
- Now the object of the invention is to provide a more simple subfloor-assembly which provides a better sound damping effect.
- A subfloor-assembly according to the invention is characterized in that said lower part is formed by a lower plate from a resilient wood fibre material, said top plate comprises a cement-bonded fibre board, said lower plate and top plate being glued to one another by using adhesive layers, a further layer of a latex-bonded mixture of coconut and wood fibres being applied onto said top plate (14) and being connected to it by gluing, the subfloor-assembly being designed in such a way that, in use, an overall impact sound reduction of at least 10 dB is realized.
- Concerning
EP-A-0 904 932 it can be remarked that this known floor material mainly consists of various layers of cork, such that this floor material is not suitable for supporting flooring elements, which are formed by ceramic or natural stone elements. -
DE-A-199 16 353A shows a subfloor-assembly consisting of a number of layers, the upper one being formed by a cement-bonded wood material. - Further
US-A-3 902 293 shows a multilayer floor tile being suitable as a basketball floor and so not suitable for being covered by ceramic or natural stone elements. - According to the invention described above, it is provided for that the top plate comprises a cement-bonded fibre board. Such 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.
- As lower plate, is employed a plate of wood fibre material with 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 is improved further by applying a layer composed of a latex-bonded mixture of coconut and wood fibres onto the top plate. Important for its structure and properties is that this further layer is fixedly connected to the top plate. To that end, according to the invention it is provided for that 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. According to a further development it is provided for that 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. Thus, 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. According to a further development, it can also be provided for that 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. By employing fixed dimensions, a normalization for making ducts can be established, so that they are always fitted on the same location. This offers great advantages over the present method in which one more or less chooses the shortest way for the ducts and/or the ducts are situated partly in a poured concrete supporting floor.
- With such a covering floor, it is preferably provided for, that at least the top plates are provided with a groove and tongue system for mutual engagement of the subsequent parts of the subfloor. Using such a system, 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.
- Further, for stabilisation and sound insulation in all embodiments it is essential that the lower and top plates can be intimately connected to one another. This can be realized effectively by mutually glueing the plates. According to a further development of the invention it can be provided for, that 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. Then, according to a further development, the lower plate is provided with a paper layer, namely a paper layer having the important property of engaging a fibre structure particularly well.
- Preferably, 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. As a result of this property a subfloor system is achieved which can be processed easily and in which an excellent mutual adherence between the plates can be established.
- Further, when using ceramic or natural stone floor elements it is of utmost importance that these can be fixedly applied onto the subfloor. To this end, according to the invention a two component mortar is provided, the first component comprising a synthetic resin and the second one a cement. In order to prevent a possible movement in the subfloor, e.g. due to a local heavy load, from resulting in disengagement of one or more ceramic or natural stone floor elements, it is preferably provided for, that 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 egaline 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.
- The joints between the applied ceramic or natural stone floor elements are filled with 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.
- The subfloor according to the invention is further explained by way of the example given in the drawing, in which
- fig. 1
- illustrates schematically laying pattern for an assembly of lower and top plates;
- fig. 2
- illustrates schematically a cross-section of an assembly of lower and top plates which does not show the invention, but shows some features which can also be applied to a subfloor-assembly according to the invention.

- fig. 4
- illustrates a cross-section of a variation of the second embodiment of an assembly of lower and top plates.
-
Fig. 1 shows anassembly 1 oflower plates 2 andtop plates 3 applied floatingly on a supportingfloor 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 naturalstone 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 betweentop plates 3. -
Fig. 2 shows a cross-section of an assembly oflower plates 2 entop plates 3, with ceramic or naturalstone floor elements 5 being mounted ontop plates 3. This figure does not show the invention, but it shows some features which can also be applied to a subfloor-assembly according to the invention. In the example given, thelower plate 2, a soft wood fibre plate (softboard), is floatingly mounted on the supportingfloor 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 andtop plate 3 are glued to one another, to which end a specialadhesive layer adhesive layers - In order to achieve a good adherence of the
adhesive layer 6 on thelower plate 2, apaper layer 8 is applied on saidlower 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 naturalstone floor elements 5. For reinforcing said layer, additionally, a reinforcinglayer top plate 3 form an entity together with upper reinforcing layers of the further top plates,glass fibre strips 11 have been applied across the joints between the adjacent top plates. Preferably, self-adhesiveglass fibre strips 11 are applied. - A
mortar layer 12 having somewhat resilient characteristics is applied on the mutually connectedtop plates 3, through which layer the ceramic or naturalstone floor elements 5 are fixedly connected to the subfloor. For jointing the ceramic or naturalstone floor elements 5 one uses a specialjoint mortar 13 which is likewise slightly resilient, but which need not have the specific properties of saidmortar 12. - Sound reduction with such an assembly of plates with a lower soft wood fibre board having a thickness of 15 mm, a top, polystyrene plate, commercially available under the designation XPS, having a thickness of 10 mm and applied thereon ceramic tiles of 30x30 cm, as measured by TNO, is according to the old standard NEN 140-8 and the new standard NEN-EN-ISO 717-2, respectively:
- With this assembly, the required standard is already met at a relatively small thickness, the assembly furthermore being suitable for supporting the most heavy types of floorings.
-
Fig. 3 shows an example of the invention in which the cement-bondedwood fibre board 14 is a cement-bonded chipboard, for example. The same reference numbers have been used for the further constituent parts corresponding to those in the example offig. 1 . Thewood fibre board 14 has a much higher specific density than thelower 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. Sound reduction for the assembly of lower andtop plates - An additional sound-reducing
mat 16 of latex-bonded coconut and wood fibres has been applied on thetop plate 14. Thismat 16 is fitted in the mortar,tile glue 12 is applied on cement-bondedplate 14. Sound reduction for the assembly of lower andtop plates mat 16 having a thickness of 4 mm, glue not included, and a covering of ceramic tiles of 30x30 cm, as measured by TNO, is according to the old standard NEN 140-8 and the new standard NEN-EN-ISO 717-2, respectively: -
Fig. 4 shows a variation in which afurther plate 17 of a soft and/or resilient fibre material, e.g. softboard, has been applied underneath said assembly offibre board 2 and cement-bondedwood fibre board 14. In this variation, theplates groove 19 andtongue 18 system has been provided by which the consecutive assembledplates fig. 3 , by way of example. -
Further plate 17 is provided withslots 20, which can be made by milling them fromplate 17 or by spacingcertain plates 17 so that a continous slot arises between them. It is also possible to provide a certain part of theplates 17 with a slot beforehand or theplates 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. Theslots 20 are intended for receivingpipes - Sound reduction for the assembly of lower and
top plates further plate 17 having a thickness of 30 mm, thus a total thickness of 60 mm, without any further covering, as measured by TNO, is according to the old standard NEN 140-8 and the new standard NEN-EN-ISO 717-2, respectively: - 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.
- 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.
