Definitions

  • the present invention relates to a floor structure for insulat ⁇ ing footfall sound and to a method for forming such a floor structure.
  • the surface finishing material is in ⁇ stalled before the final drying of the concrete, for example fungal damage and swelling of the parquet may result.
  • the surface finishing material may be in ⁇ stalled at the earliest a couple of months after the casting of the floor.
  • the covering concrete slab must be at minimum approx. 40-50 mm thick in order to be sufficiently strong. This is a disadvantage, especially in the construction of a sound-insulating renovation floor, in which in particular maximally thin floor structures are aimed at.
  • a further disad ⁇ vantage of the use of concrete in this technique is that its spreading requires auxiliary leveling tools, and therefore the making of such a floor is a slow procedure.
  • This prior-art fiber-reinforced slurry screed for floors forms, upon hardening, a surfacing with excellent mechanical proper ⁇ ties, and it is applicable to uses which have conventionally been regarded as problem areas, for example, the leveling of weak concrete, wood, and various compound floors, such as mag- nesite floors and gypsum mix floors.
  • This publication includes no mention that the slurry screed described in it could be used together with a resilient footfall-sound absorbing material to form for a concrete floor a thin covering structure which has excellent footfall-sound insulation properties.
  • the highest permitted value for the footfall-sound level In most countries, requirements have been set for the highest permitted values for the footfall-sound level. In Finland the highest permitted value for the footfall-sound level (L' n w ) from one residential apartment to another is 58 dB. In order to attain this permitted value, the intermediate floors of apart ⁇ ment buildings must often be made thicker than required by strength standards. The highest permitted value for the footfall-sound level also sets restrictions with respect to the choice of the surface finishing material.
  • a mosaic parquet or clinker cannot in an apartment building be installed directly on top of a concrete floor, a hollow-core slab, a solid slab, or suchlike; the footfall-sound insulation proper ⁇ ties of the intermediate floor must first be improved, for example by the techniques described at the beginning of this specification, which for their part will considerably increase the total thickness of the floor structure.
  • This is highly problematic in renovation building, in which doors and thres ⁇ holds normally allow the floor level to be raised by only approx. 30 mm.
  • the object of the present invention is to provide a floor structure by means of which the problems associated with the footfall-sound insulated floor structures described above are avoided and a good level of footfall-sound insulation is achieved by using structural thicknesses considerably smaller than the conventional ones.
  • the slurry screed for floors known from the above- mentioned FI Patent 76545, can be used together with a resil ⁇ ient footfall-sound absorbing material to form a very strong and thin covering structure on a floor, thus producing a floor structure having excellent footfall-sound insulation proper ⁇ ties.
  • the above-mentioned covering structure can be formed on a concrete floor as early as two days after the cast ⁇ ing of the floor.
  • slurry screeds for floors known from FI Patent 76545 but also any other slurry screeds which are cement-based, fiber-reinforced, self-leveling, rapidly hardening, rapidly drying and shrinkage-compensated.
  • a footfall- sound insulating floor structure which comprises a layer com ⁇ bination which has a resilient, footfall-sound insulating mate ⁇ rial layer in the form of a mat or a board and, cast on top of this material layer, a layer approx.
  • a method for forming a footfall-sound insulating floor structure in which there is installed on top of a new concrete floor the thickness of which is determined by footfall-sound standards, alternatively the strength standards, or on top of an existing load-bearing base, a resilient footfall-sound absorbing layer of material in the form of a mat or a board, and on top of this material layer there is introduced a layer approx. 15-35 mm thick of a cement-based, fiber-reinforced, self-leveling, rap ⁇ idly hardening, rapidly drying, and shrinkage-compensated slur ⁇ ry screed.
  • the said resilient footfall-sound absorbing layer of material is preferably a closed-cell plastic mat or board, or a mineral- wool mat or board, of a combination of the same.
  • the thickness of the mineral wool mat is approx. 4-15 mm.
  • the upper surface of the mineral wool mat is preferably equipped with a plastic membrane, such as a polyethylene membrane, in order that the slurry screed should not penetrate into the mineral wool mat.
  • the thickness of the mineral wool board is
  • the upper surface of the mineral wool board can also be equipped with a plastic membrane.
  • the said closed-cell plastic mat or board is preferably a mat or board of foamed polyethylene, polystyrene or styrene- butadiene copolymer.
  • the thickness of the mat is approx. 4-15 mm " and the thickness of the board is approx. 15-50 mm.
  • a par ⁇ ticularly preferred material is an approx. 5-mm-thick foamed polyethylene mat.
  • a mat-like material has the advantage that it can easily be folded up against a wall, whereby a floating structure is obtained.
  • the resilient footfall-sound ab- sorbing material layer may comprise two or more mats and/or boards one on top of the other, for example two mineral wool mats one on top of the other or a mineral wool mat and a foamed polyethylene mat fitted on top of it.
  • the thickness of an individual mat may be as small as 2 mm.
  • composition of the self-leveling, rapidly setting and rap ⁇ idly drying slurry screed is preferably as follows:
  • the binder is preferably cement
  • the aggregate is preferably sand
  • the filler is preferably fly ash.
  • the adhesive agent used may be, for example, a polyvinyl ace ⁇ tate powder, and the shrinkage-compensating agent used may be, for example, gypsum.
  • the fluidifier, i.e. the flow-promoting agent may be, for example, Melment (trademark, manufactured by SKW) .
  • the said fibers are preferably synthetic polymer and/or carbon fibers, particularly polyolefin, polyacrylic nitrile and/or polyvinyl alcohol fibers.
  • Polypropylene fibers are especially preferred.
  • the length of the fibers is preferably 1-20 mm, especially preferably 5-7 mm.
  • the said slurry screeds may additionally contain a small amount, preferably less than 1 % by weight, of various admix ⁇ tures, for example anti-foaming agents and retarders, such as gypsum retarder.
  • the said layer combination i.e. a resilient footfall-sound absorbing material layer and a slurry screed layer
  • a new concrete floor such as an in situ cast concrete floor
  • hollow-core slabs on solid concrete components and on air- entrained concrete components.
  • the said new con ⁇ crete floor can be made considerably thinner and lighter than corresponding conventional concrete floors while producing the same or even better level of footfall-sound insulation.
  • commercial hollow-core slabs must normally be made 265 mm thick in order to achieve a sufficient level of footfall- sound insulation even when strength standards do not require so thick a structure.
  • hollow- core slabs may be made 200 mm thick and be covered with the said layer combination, whereby a sufficient level of footfall- sound insulation and at the same time a light overall structure are achieved.
  • the components constituting the intermediate floor usually have to be leveled before the installation of the surface material. Nor ⁇ mally the leveling is carried out by spreading on top of the components a slurry-screed layer approx. 10-20 mm thick.
  • the resilient footfall-sound absorb ⁇ ing mat or board is installed directly on top of the com ⁇ ponents, and then slurry screed is pumped on top of the mat or board.
  • the said layer combination can be formed on top of an already existing load-bearing base, which may be a concrete floor of any of the above-mentioned types or, for example, a wooden floor or a floor made of shell-structured slabs.
  • This layer combination may be made considerably thinner than conventional systems, even as thin as 20 mm, and is thus excellent for renovation building. Normally doors and thresholds will allow the floor level to be raised by approx. 30 mm.
  • the composite layer which contains a closed-cell plastics material as the footfall-sound absorbing material can be formed on top of a concrete floor which has not yet completely dried, for example 2-14 days after its casting. In this case the moisture from the base concrete will evaporate downwards. In new building this will considerably speed up construction work. Furthermore, the slurry screed used in the invention dries and hardens rapidly, and so the surface finish ⁇ ing material can be installed as early as a few hours after the slurry screed has been pumped on top of the closed-cell plas ⁇ tics material.
  • three persons can in one working day make up to 1,000 m of such concrete-floor covering structure, which comprises a layer of a footfall-sound absorbing material and a slurry screed.
  • a mineral wool mat and/or a foamed polyethylene mat was in ⁇ stalled on top of a solid concrete slab or a hollow-core con ⁇ crete slab.
  • a 20-mm-thick layer of the completely self-leveling slurry screed described above was cast on top of this mat.
  • the footfall-sound insulation capacity of the structure thus formed was determined according to the following methods: ISO 140/6 and 8-1978 (L n ) and ISO 717/2-1982 (footfall-sound level L n w ) .
  • Any surface finishing material for example hard materials such as clinker, can be used on these intermediate floors in apart ⁇ ment buildings.
  • Example 2 A structure similar to that described in Example 1 was formed by using a 265-mm-thick hollow-core slab, a 5-mm-thick foamed polyethylene mat, and on top of it a slurry-screed layer as de ⁇ scribed in Example 1. On top of this structure, a mosaic par ⁇ quet or clinker was installed as a surface finish.
  • results show that, because of the footfall-sound insulation standards, a 265-mm-thick hollow-core slab with a 10-mm-thick layer of slurry screed cannot be surface finished with a mosaic parquet or clinker.
