Definitions

  • the invention relates to a hollow floor with an upper floor resting on supporting feet on a sub-floor and forming a cavity with the lower floor, to which the supporting feet in the form of circular knobs which have filled with the material of the upper floor and form a smooth coating are molded on, whereby the support feet form a vault-like structure without flat side surfaces and continuously widen upwards and merge into the horizontal top floor without kinks.
  • a known hollow floor of this type (US-A-3 442 058) has support feet which are formed by pouring molded parts with screed. These molded parts consist of pre-cast concrete, plaster, glazed clay or the like, in any case from a rigid material. The molded parts are open on the undersides of the support feet. If a hollow floor is made from such molded parts, it can happen that the lower ends of the individual molded parts do not or not fully stand on the sub-floor, because the sub-floor is either rough or uneven. This is particularly the case if the sub-floor consists of raw concrete. In such cases, the filled concrete swells out of the lower ends of the support feet and forms a base with an irregular, rough outside on the sub-floor.
  • a hollow floor in which the molded parts forming the feet consist of a plastic and are closed at the bottom (DE-C-1 123 817).
  • the molded parts have flat side surfaces to form a honeycomb structure.
  • the molded parts serve as a moisture barrier, as a tub against groundwater and to create an air cushion for thermal insulation. Your feet don't hit the floor at almost a right angle.
  • the top shelf always consists of plates that can be picked up individually.
  • the invention has for its object to form a hollow floor of the type mentioned in such a way that it is suitable for the subsequent retraction of cables, hose lines and other lines without them tightening at deflection points on the support feet.
  • the material from which the formwork is made is so flexible and supple that it adapts to any unevenness in the sub-floor when exposed to screed.
  • This surface material is covered with the plastic mass, which not only fills the bulges of the surface material, which are directed downwards and later form the support feet, but also forms the top floor.
  • the leveling is carried out on the surface of the top floor and not on the support feet supporting the top floor. This eliminates the leveling work otherwise required.
  • the formwork made of the sheet material prevents the flowable mass from penetrating. It must therefore have such a tightness that it forms the underside of the top floor and the outside of the support feet without a substantial amount of the flowable mass getting into the cavity formed between the surface material and the underbody.
  • the flowable mass preferably consists of a self-leveling suspension which automatically forms an exactly horizontal and smooth surface. However, the flowable mass can also have a paste-like consistency, which, however, requires mechanical smoothing.
  • the surface material remains like a lost formwork on the top floor and the support feet and forms a coating on the wall of the cavity.
  • This smooth coating preferably consists of a relatively hard pressure distribution layer, which is arranged on a relatively soft insulation layer.
  • the insulation layer is used for heat and sound insulation. It consists of a soft material, such as foam or fiberglass panels. This soft material, which provides good thermal insulation and sound insulation downwards, has a relatively soft surface. It is therefore covered with the pressure distribution layer on which the feet of the top floor stand. The pressure of the feet is distributed over a larger area of the insulation layer over the pressure distribution layer so that it does not suffer any local impressions.
  • the pressure distribution layer is provided with holes for sound absorption.
  • the airborne sound penetrates through the holes into the insulation layer and is absorbed in it. In this way, multiple reflections of the airborne sound in the cavity are avoided.
  • the profiled surface material can be in the form of a sheet or in sheet form, the sheets or sheets, however, having to be connected in a sealing manner in such a way that a continuous casting mold is created for the locally cast, continuous top floor. Therefore, the edges of the surface material are usually designed as interlocking or opposable straight strips.
  • the bendable surface material can be reinforced in some areas by further meltable plastics or combined with metal inserts to improve heat conduction and stability.
  • the hollow floor shown in section in FIG. 1 consists of the sub-floor 10, 11, 12 and the upper floor 13 arranged above it Metal sheet 12 for better load distribution.
  • the metal sheet 12 has holes.
  • a mold 14 made of a deep-drawn plastic film is first placed on the sub-floor 10, 11, 12 to form the top floor 13.
  • Form 14 is self-supporting. It has numerous knobs or ribs 15 projecting downwards. The undersides of the ribs 15 rest on the sheet 12.
  • the shape 14 is flexible or bendable overall, so that it adapts to any unevenness in the underbody 10, 11, 12.
  • edges 16 of the mold 14 are designed as strips with a uniform profile that lie at the level of the raised surface areas of the mold 14.
  • the edges 16 have a groove-like bulge, so that the bulges of two adjoining molds 14 can be inserted into one another in a sealing manner.
  • the edges 16 can also be connected to one another with an adhesive or by welding, so that the plates provide an overall sealing mold for the top 13.
  • Filling bodies 25 made of rolled gravel are filled into the knobs or ribs 15 and protrude beyond the shape 14 into the area of the later upper floor.
  • the top floor 13 is produced from a self-leveling screed which is applied to the mold 14 and thereby encloses and embeds the filler 25.
  • the support feet 17 are formed in the ribs 15 of the mold 14 and a layer 18 covering the entire mold 14 is formed over it forms. The height compensation takes place in that the layer 18 is given different thicknesses at different points if necessary.
  • the mold 14 When the liquid screed has hardened, the mold 14 remains in the hollow floor, so that it forms a smooth coating which closely surrounds the support feet 17. If electrical cables or other pipelines are introduced into the cavity, they slide along the coating so that they do not come into contact with a relatively rough concrete or mortar surface.
  • FIGS. 3 and 3 A hollow floor is shown in FIGS. 3 and 3, in which the feet 17 are also circular knobs, each of which has the same distances from one another.
  • the support feet 17 are arranged in rows and the support feet of two rows are each in a gap. This creates a uniform load-bearing structure and load distribution. In addition, straight channels for the passage of air are avoided within the hollow floor. The air is swirled and branched at the support feet 17, so that the heat transfer to the top floor 13 is improved.
  • a vaulted structure i. H. the diameter of the support feet 17 widens upwards, so that each support foot - seen in cross section - merges into the adjacent support foot in the form of an arc.
  • This vaulted structure also increases the load-bearing capacity of the top floor 13, so that the continuous top layer 18 can be made relatively thin.
  • This film consists of some areas of the hollow floor a plastic film and in other areas of the hollow floor made of a metal foil or a combined metal / plastic film in order to influence the heat transfer from the cavity into the material of the top floor 13.
