Definitions
- the invention relates to a cavity floor, comprising a profiled Intermediate floor arranged between an upper and a lower floor and is plate-shaped, the intermediate bottom pot-shaped Has depressions through substantially flat edge areas connected together and filled with a sound-absorbing filler and wherein on the side of the bottoms facing away from the depressions Wells each a foot muffler is arranged, which the floor in essentially completely covered
- Such a cavity floor is known from DE-U-93 18 517.
- the cavity floor is designed to accommodate underfloor installations and is manufactured using the press or thermoforming process.
- the sound-absorbing filler which consists of a closed-cell foam body with a density of 20 to 70 kg / m 3 , provides impact sound insulation.
- the cup-shaped depressions are circular in cross-section.
- Raised floor has a profiled and covered with screed Floor film with truncated cone-shaped feet, the Floor film adjusts unevenness of the sub-floor and is accessible.
- the Floor film forms a formwork for the screed material to be applied, the forms the topsoil.
- the floor film is plate-shaped and as thin as possible formed so that adjacent foil plates loose at their edges can be laid one on top of the other without steps in the screed layer.
- the invention has for its object a cavity floor of the known Kind to develop in such a way that internal tensions in the screed, the Forms topsoil and avoid that the screed is shorter Has drying time.
- the raised floor is also said to be a good one Have impact sound insulation and in manufacturing technology and economical Regarding be simple and inexpensive to manufacture.
- the The muffler has the shape of a regular hexagon.
- the depressions in the intermediate floor do not form the screed that forms the top floor are filled out, but with a sound-absorbing filler, the Screed drying time by avoiding material accumulation in the The area of the depressions is significantly shortened and internal tensions within the Avoid screed reliably.
- a transmission of annoying impact sound from The top floor on the underbody is covered with the soundproofing Filler-filled depressions significantly reduced.
- the sub-floor mostly consists of concrete, on which the Intermediate floor liquid screed material applied to produce the top floor becomes.

- the force acting on the intermediate floor is essentially determined by added the filler.
- the filler can be held in the recesses in an adhesive and / or form-fitting manner be.
- an adhesive and / or form-fitting manner be.
- the filler during curing claws with the adjacent surfaces of the floor film and thereby is held positively in its position.
- the edge areas can be used to improve their dimensional stability at least one bead, preferably at least two beads apply to each other at an angle of substantially Cut through 90 °.
- the increased Dimensional stability the laying of the intermediate floor on the sub-floor simplified.
- the filler is preferably formed by a PU foam.
- the bulk density of the filler is 50 to 120, preferably 60 to 100 kg / m 3 for most applications.
- Such a filler has a comparatively high load-bearing capacity, prevents screed from penetrating into the recesses and provides good impact sound insulation when walking on the cavity floor.
- the filler can also be formed, for example, by a one-piece rubber cork body, which is inserted into a depression and is adhesively connected to it, for example.
- the rubber cork bodies preferably consist of recycled components that are pressed together. The advantage here is that the mezzanine floor can be produced particularly economically in an economical manner.
- the depressions are each designed to match and that the ratio of the largest diameter and height 0.6 to 1.8, preferably 0.8 is up to 1.2.
- the design of the depressions shows the intermediate floor to a high degree Load capacity, with a buckling of the wells even when initiated of transverse forces, for example when walking on the intermediate floor for application of the screed is reliably avoided.
- the depressions are frustoconical and are provided with stiffening ribs that run along the entire height of the Extend depressions and are evenly distributed in the circumferential direction.
- stiffening ribs By which taper in the shape of a truncated cone towards the underbody Wells also arise compared to being substantially cylindrical trained depressions a relatively enlarged cavity for laying Connection cables and hoses.
- stiffening ribs can contribute to the material thickness of the intermediate floor specified minimum resilience can be further reduced.
- the intermediate floor can be formed by at least two separately produced individual elements be formed by each other by at least one fastening device can be determined.
- the intermediate floor is the laying of the intermediate floor and its handling is significantly simplified.
- the individual elements can have external dimensions that the Euro pallet size correspond so that an optimal transport space allocation at Truck and / or train loading is guaranteed.
- the fastening device can be formed by a push button system with at least one cup-shaped bulge of the first individual element at least one congruently shaped recess or recess of the second Individual element can be brought into engagement.
- the thickness of the inserted Material thickness of the partial area of the individual element corresponds to that Top floor is facing.
