Definitions

  • the invention relates to a hollow floor with a sub-floor and a support feet resting on the sub-floor and with this an upper floor enclosing a cavity.
  • the sub-floor consists of a concrete layer over which an insulating layer is arranged.
  • the support feet on which the top floor rests protrude through recesses in the insulation layer and stand directly on the concrete layer.
  • the disadvantage here is that the insulation layer does not dampen the impact sound.
  • the impact sound is rather transmitted from the top floor directly to the concrete layer via the support feet.
  • the support feet which are mostly made of metal 'may additionally also form cold bridges.
  • the invention has for its object to improve a hollow floor of the type mentioned with regard to thermal insulation and sound insulation.
  • the subfloor has a pressure distribution layer above an insulation layer, which is more sensitive than the insulation layer.
  • the insulation layer extends without interruptions over the entire area of the hollow floor - possibly with the exception of marginal areas that can be neglected. This significantly reduces heat losses downwards. It should be taken into account here that the voids of raised floors can be used as underfloor heating if warm air is introduced into them. This warm air is primarily intended to heat the top floor, while the bottom floor is to provide heat shielding and insulation downwards.
  • the pressure distribution layer has numerous openings. These openings are used for sound absorption. They cause in the cavity, for example as a result of - can penetrate air turbulence occurring airborne sound in the insulating layer, where it is absorbed.
  • the top of the pressure distribution layer is profiled in such a way that the support feet or only part of its height are molded onto it.
  • the cavity of the hollow floor extends not only into the area of the support feet or the upper floor, but also into the area of the lower floor. This increases the usable cavity or improves the ratio of the cavity to the total volume of the raised floor.
  • the pressure distribution layer can either consist of an essentially continuous layer produced by casting or of prefabricated plates placed against one another. It is preferably provided that the joints between the plates of the pressure distribution layer are arranged offset from the top floor joints in plan view. This prevents the board edges from pressing into the insulation layer.
  • the cavity delimited by a formwork for the top floor made by cast-in-place is laterally closed by profile strips.
  • the profile strips prevent the pouring compound of the top floor from entering the cavity. They are arranged along the edge of the raised floor.
  • the casting compound that forms the top floor then creates a solid block between the wall and the cavity of the raised floor, so that no special measures for adapting the mold of the top floor to the side wall of the room are required.
  • the profile strips preferably consist of interconnectable modules, the lengths of which are graduated in the grid dimension of the support feet.
  • the cavity of the hollow floor usually serves as warm air underfloor heating.
  • the lower and / or the upper boundary wall of the cavity at least in places with a heat ; reflective coating.
  • a coating on the boundary wall of the cavity generally brings about a lowering of the floor temperature at this point. In this way, the heat distribution in the raised floor can be influenced by targeted distribution of heat-reflecting coatings.
  • the pressure distribution layer consists of prefabricated panels, there may be gaps between the edge panels and the neighboring building wall. In order to avoid that these gaps have to be filled in by elaborate cutting of plates, it is provided according to a preferred development of the invention that the pressure distribution layer has lateral edges which extend over the entire height of the cavity and that the space between one of the edges and the neighboring wall is filled with the material of the top floor or another material.
  • the side edge also acts as formwork to delimit a pouring ledge to be made along the wall.
  • the subfloor 10 consists of a concrete layer 11 on which an insulation layer 12 is arranged, and the pressure distribution layer 13 covering the insulation layer 12.
  • the insulation layer 12 serves both for thermal insulation and sound insulation. It can consist of foam, fiber mats or another heat and sound insulating material. Since the insulation layer 12 is relatively soft, the pressure distribution layer 13 made of a harder material is arranged above it.
  • the pressure distribution layer 13 in the present case consists of a perforated steel sheet, the holes of which are designated by 14.
  • the top floor consists of a mass of screed, gypsum or the like applied to a lost formwork 17 in a flowable form, which fills the formwork 17 and one for the formwork 17 Load-bearing capacity forms a sufficiently strong layer.
  • the formwork 17 consists of a load-bearing plastic film from which the support feet 16 are shaped in the manner of an egg carton. Between the support feet 16 are arcuate over gears so that the vault-like cavity 18 is formed in the top floor 15 between the support feet 16. Air can be directed into this cavity for heating or cooling purposes.
  • the formwork 17 has such a load-bearing capacity that it initially carries the mass 19 which is applied in a flowable manner. This mass 19 then hardens and forms the supporting structure of the upper floor 15.
  • the support feet 16 taper downward, their side walls abutting the pressure distribution layer 13 at almost right angles.
  • the formwork 17 consists of prefabricated profiled plastic plates which are placed on the pressure distribution layer 13. In order not to have to cut these panels to size so that they each extend to the side wall 20 of the room or building, a profile strip 21 is laid under the edge of the outermost panel, which laterally delimits the cavity 18. The edge of the formwork 17 is fastened in a sealing manner on this profile strip 21 with an adhesive tape 22. The edge of the pressure distribution layer 13 lying outside the profile strip 21 is covered with a tough pasty mass 23, which covers the holes 14 in this area.
  • a block .19 ' is formed between the wall 20 and the profile strip 21, which projects up to the wall 20.
  • the block 19 ' is separated from the wall 20 only by a separating strip 24, which consists of a sound-absorbing material, for example foam. In this way, the transfer of body prevents sound between the top floor 15 and the side wall 20.
  • the pressure distribution layer 33 consisting of individual prefabricated plates is placed on the insulation layer.
  • the pressure distribution layer 33 has a smooth underside and a profiled top.
  • the elevations 34 are provided, on which the downward-facing lugs 35 of the top floor are placed.
  • the elevations 34 and the lugs 35 each form a support foot.
  • the elevations 34 are each between troughs of the pressure distribution layer 33, so that the cavity 18 is partly formed in the interior of the underbody 10 and another part in the interior of the upper floor 15.
  • the tops of the elevations 34 are each surrounded by a centering ring 36, in which an extension 35 of the top plate 15 is centered.
  • the projections 35 are omitted and the elevations 34 extend to the flat underside of the top floor.
  • the edge 37 of the pressure distribution layer 33 facing the side wall 20 is raised in the embodiment of FIG. 3 up to the upper limit of the cavity 18.
  • the end of the formwork 17 is placed on the top of the edge 37 and glued there.
  • the space between the edge 37 and the section 32 of the insulation layer resting against the wall 20 is filled with the mass 19 of the top floor 15. This mass extends down to the insulation layer 32 in the space mentioned.
  • the sub-floor 10 has a concrete slab 11, which is covered by the insulation layer 32.
  • a section 32 ′ of the insulation layer 32 protrudes a little from the wall 20.
  • the sub-floor 10 also includes the plates 38, which lie with their flat undersides on the insulation layer 32 and have upstanding support feet 39.
  • the upper floor 15 consists of the flat plates 40, which lie on the upper sides of the support feet 39 and whose gaps are sealed by elastic joint seals 41.
  • the troughs 42 between the support feet 39 limit the cavity 18 in connection with the plates 40.
  • the cross section of the support feet 39 decreases upwards, so that the vertical contact forces which are transmitted from the plates 40 to the support feet 39 via the relatively rigid panels 38 are evenly distributed over the relatively soft insulation layer 32.
  • the edge 43 of the outer plate 38 facing the wall 20 forms a continuous edge strip 43.
  • the space between the section 32 ′ of the insulation layer 32 resting against the wall 20 and the edge strip 43 is filled with a screed filler 44, on the top of which the outermost plate 40 rests.
