Description

IMPROVE)ffNTS IN ND RELATING TO FLOORING
FIELD OF INVENTION
This invention relates to building components, and in particular, to flooring components. The invention also relates to building systems or flooring systems comprising such components. The invention particularly, though not exclusively, relates to a so-called acoustic floating floor or platform floor.
BACKGROZJND TO INVENTION
Known acoustic floating floor panels and systems provide fixed acoustic insulating properties that cannot be altered unless a different density or stiffness of resilient material is used. Even then the performance difference can be profound because of the limited choice of densities available.
It is also known that to overlay structurally different sub-floors with any one of the presently known panels will improve the acoustic performance to varying degrees. However, such use is based on the understanding that it is acceptable so long as it achieves a minimum performance.
All present systems comprise a plurality of timber chipboard or like panels, each of area around 0.5m2 to P15269GB 1.5m2. The panels are tongued and grooved to slot and be glued together to form a continuous deck that is laid on top of an existing structural sub-floor.
Present panels comprise the aforementioned timber panel having bonded to an underside thereof a layer of resilient material. This resilient material bears the weight of the floor board and absorbs impact shocks. The known floor panel is generally selected with the mass of the sub-floor in mind on the basis of "one resilient layer fits all". This encourages only the softest or lightest resilient layers to be used with the lowest dynamic stiffness.
There are other known acoustic damping flooring systems comprising a panel, e.g. a chipboard panel supported by battens or cradles that perform by suspending the panel above the structural sub-floor to accommodate services such as water and electricity. These systems are known to perform better than platform floors because there is less contact by the floating floor with the sub-floor. However batten and cradle systems are of considerably greater depth (commonly 50mm plus), and can often be discounted because of the lack of floor to ceiling height. Cradle systems are also considered unsuitable for timber sub-floors because point loads, P15269GB which they create, will often occur on unsupported parts of the sub-floor.
Different timber structural sub-f loors perform acoustically differently because of the differing stiffness of the floor boards and/or the joists due to spacing, span, depth or even the type. Acoustic floors need to resonate independantly of the sub-floor, since if it were found to resonate in unison with the sub-floor it would render the acoustic floor considerably less affective.
Because known platform floors absorb impact sound over their entire area, it follows that the resilient layer needs to be softer than that of a cradle or batten system. Therefore when the soft resilient layer is in the loaded state it follows that it will be substantially thinner (proportionately) than in the unloaded state.
In the prior art platform acoustic floors are
characterised in that the resilient layer extends substantially with continuous thickness underneath the whole of the floor deck, the resilient layer typically comprising a foam layer comprising a plurality of foam, rubber or resilient fibres/particles. The resilient layer currently has a continuous thickness in the range 5mm to 16mm, which is bonded to the underside of the floor deck commonly made of chipboard, plywood or medium P15269GB density fibreboard, ranging from 9mm to 30mm, and suitably of the order of 18mm 5mm.
It is an object of the present invention to provide an acoustic floating floor with a variable performance to treat different structural sub-floors. The invention seeks to provide the ability to use a common resilient material of the same overall dimensions (length, breadth, thickness), but configured or shaped to achieve varying performances. Not only can the invention be designed to seek to maxjmise the acoustic performance, it will also enable the use of recycled or reconstituted materials that would otherwise be considered too dense or possess too high a dynamic stiffness.
It is an object of at least one embodiment of at least one aspect of the present invention to provide a flooring component for construction of a vibration insulating flooring deck or platform acoustic floating floor.
It is an object of at least one embodiment of at least one aspect of the present invention to seek to obviate or at least mitigate one or more
disadvantages/problems in the prior art.
It is an object of at least one embodiment of at least one aspect of the present invention to provide an improved acoustic floating platform floor.

P152 69GB Advantageously raised portions of the at least one flooring component can be disposed parallel to or at right angles to joists and/or floor boards of the sub-floor.
The building may be a new build structure or a conversion.
According to a sixth aspect of the present invention there is provided a method of forming a floor, such as an acoustic floating floor or platform floor, comprising the steps of: providing a flooring system according to the second aspect of the present invention; and laying the flooring system on a sub-floor.

Embodiments of the present invention will now be described by way of example only, and with reference to the accompanying drawings which are: Figure 1 a cross-sectional end view of a first floor construction comprising a floor component according to a first embodiment of the present invention; Figure 2 a cross-sectional end view of a second floor construction Comprising a floor 915269GB component according to a second embodiment of the present invention; Figure 3 a perspective view from above and to one side of the floor component of Figure 2; and Figure 4 a perspective view from above and to one side of the overall floor construction of Figure 2 illustrating more clearly existence of floor structure (comprising floorboards) as part of the sub-floor.
DETAILED DEScRIpTION OF DRAWINGS
Referring initially to Figure 1 there is shown a flooring system, generally designated 5, comprising a flooring member or component 10 according to a first embodiment of the present invention. The flooring system is provided on a sub-floor 15. The sub-floor 15 comprises a floor structure 20, a ceiling structure 25 and a plurality of joists 30 spaced at centres, and optionally insulation (not shown), e.g. between the joists 30. There may also be provided noggins (not shown) between joints 30.
The flooring component 10 comprises a substantially planar resilient member 35 having a plurality of raised portions 40.
P15269GB The substantially planar resilient member 35 comprises a first surface 45, the plurality of raised portions 40 being provided thereon. The substantially planar resilient member 35 comprises a second surface 50, which is substantially planar.
The first surface 45 is adapted to comprise a lowermost surface, in use. The raised portions 40 therefore comprise contact portions, which, in use, contact a sub-floor 15 upon which the flooring component 10 is laid.
The flooring component 10 comprises a substantially rigid panel, board or deck 55. The second surfaces of the substantially planar resilient member 35 is fixed to the deck 55, e.g. by adhesive or glue.
In this advantageous embodiment each raised portion comprises an elongate raised portion.
Further, adjacent raised portions 40 are spaced from one another and are substantially parallel to one another.
In this embodiment the first surface 45 of the substantially planar resilient member 35 therefore comprises a ridged, waved or corrugated surface.
As exemplified, the first surface 45 is in the form of a sine wave -having an amplitude and frequency. Both of these can be selected to provide a desired performance P15269GB of the flooring component 10 dependent upon the structure of the sub-floor 15, e.g. joist spacing, span and depth.
The resilient layer 10 typically has a density in the range 10kg/rn3 to 600kg/rn3. Peaks of adjacent raised portions 40 are typically spaced by around 50mm to 600mm.
In this embodiment a wavelength of the wave is therefore be around 50mm to 600mm.
A thickness of the substantially planar resilient layer 10 is typically at least 1mm to 2mm and typically 3mm to 5mm between adjacent raised portions 10. A thickness of the substantially planar resilient layer 10 is typically 50mm or less at the raised portions.
The substantially planar resilient layer 10 comprises reconstituted foam or rubber, or a (lighter cross-linked) closed cell polyethylene or polyurethane foam. Alternatively, the substantially planar resilient layer 10 comprises rubber, felt, flax, cork or (light) fibrous insulation or wadding.
The panel or board comprise timber, chipboard, plywood, medium density fibreboard or the like.
Thus there is provided a building or floor 60 comprising at least one flooring component 10 according to the present invention.
P15269GB The at least one flooring component 10 is provided on sub-floor 15, e.g. a structural sub-floor, which is a timber sub-floor.
The sub-floor 15 comprises a party floor or separating floor, e.g. in a multi-storey dwelling or between such dwellings.
As can be seen from Figure 1, advantageously the raised portions 40 or ridges of the at least one flooring component 10 are disposed parallel to or at right angles to the joists and/or floor boards of the sub-floor.
In use, the floor 60 is formed by the steps of: providing flooring system 5; and laying the flooring system 5 on sub-floor 15, such that raised portions 40 contact floor structure 20.
Referring now to Figures 2 to 4 there is shown a flooring system, generally designated 105, comprising a floor member or component 110 according to a second embodiment of the present invention. The flooring system and flooring component 110 are similar in many respects to the flooring system 5 and flooring component of the first embodiment, like parts being denoted by like numerals but incremented by "100".
The sub-floor 15 of the first embodiment has joists which are relatively wide apart, thus creating a less rigid construction. This requires appropriate selection P1S269G of the frequency or wavelength of the wave on the first surface 45 such that the flooring system 5 provides appropriate acoustic and load performance.
In contrast the sub-floor 115 of the second embodiment has joists 130 which are closer together, thus creating a more rigid structure. This requires an alternative appropriate selection of the frequency or wavelength of the wave on the first surface 145 such that the flooring system 105 provides appropriate acoustic and load performance.
As can be seen from Figure 4, the floor 160 has insulation 165 between the joists 130.
It will be appreciated that the embodiments of the invention hereinbefore described are given by way of example only, and are not meant to limit the scope of the invention in any way.
It will be understood that the invention relates to the subject of platform acoustic floor panel construction and advantageously provides a board/panel (each typically 0.5m2 to 1.5m2) bonded to an engineered or predesigned resilient layer that, in a preferred embodiment, on an under side resembles the shape of a sine wave form continuously over its entire area.
This wave can be altered in frequency during manufacture to increase or decrease the contact of the P15269GB floating floor with the structural sub-floor. Therefore the density and dynamic stiffness of the resilient layer can be substantially greater than that of current components, thus creating a floor less likely to compress under load, while still possessing the ability to improve the overall performance by changing the spacing between the peaks of the wave.
The invention acts to seek to optimise or improve the components ability to perform better on specific floor Constructions by altering the physical shape of the wave combined with the density of the resilient layer, thus ensuring reduced deflection under load.
The invention preferably utilises resilient materials such as rubber or felt and beneficially (lighter) closed cell polyethylene/polyureafl foams.
However, it could also utiljse flax, cork or (light) fibrous insulation/wadding. The thickness of any of these materials would typically range from 5mm to 50mm at the peaks, with a density range of 20kg/rn3 to 600kg/rn3. These materials can be cut from a block or extruded/moulded to form the desired shape.
It will be appreciated that a prime advantage of the present invention is that it allows for use of resilient materials which have relatively high density and reduced P152 69GB thickness as compared to resilient materials used in
prior art platform flooring systems.
Finally, it will be appreciated that while in the disclosed embodiments the periodicity of the raised portions on the first surface of the resilient member, i.e., the wavelength or frequency of the wave, has been exemplified as substantially constant, in alternative embodiments or modifications the periodicity/wavelength/ frequency may vary across at least part of the first surface.
