Definitions

  • the present invention initially relates to a spacer made of a mineral material for integration into a concrete structure. Furthermore, the invention relates to a concrete structure, in particular a concrete ceiling with such a spacer. Finally, the invention relates to a method for producing such a spacer.
  • Such spacers serve primarily the spacing of reinforcing elements during the manufacture of concrete structures, whereby on the one hand the desired distance between individual reinforcing bars or the like and on the other hand, the distance of these reinforcing elements is maintained by the formwork used in the manufacturing process.
  • Such spacers consist for example of metal or plastic and can take over design tasks in addition to the spacing function itself, in particular serve as a reinforcement. Spacers have already become known in various respects. It is for example on the DE 36 24 447 A1 Reference is made, in which an insertable into concrete insert body is described, which has a chemically bonded to a base body coating, which is connectable to the surrounding concrete.
  • Such spacers also made of mineral material, are used, for example, to carry reinforcing bars, which are subsequently poured over with concrete, to form, for example, a concrete ceiling.
  • the mentioned coating in particular the connection between the insert body and the surrounding concrete is to be improved.
  • the production cost of such insert body is high and it It must be checked on a case by case basis whether the applied coating is compatible with the respective ambient conditions.
  • Concrete structures such as e.g. Concrete ceilings are used in residential, commercial and production areas. In addition to their static load-bearing function, such concrete structures must fulfill numerous other tasks. Frequent acoustic requirements exist that can not be met by smooth concrete surfaces, so that e.g. After production of the concrete slab, separate soundproofing panels must be installed, which usually span the entire concrete floor. The installation effort for such ceilings is significant.
  • the DE 34 44 881 C2 shows a sound-absorbingschreibwand- or ceiling structure of joint-bumped mineral fiber boards, which are connected to a supporting structure.
  • the mineral fiber boards are designed as prefabricated elements and have an adhesive layer on both sides.
  • the DE 93 21 610 U1 is an acoustic ceiling of sound-absorbing lightweight panels described.
  • the lightweight panels consist of interconnected by means of synthetic resin Blähglas-, Blähton- or similar particles.
  • the insulating body has a hovwerksporige structure, which is formed from expanded glass granules in a stable binder framework.
  • the DE 44 08 177 A1 shows a noise protection wall part, in which a wall element of solid concrete is provided on one side with an open-pore absorption layer.
  • the absorption layer Contains mineral-silicate particulate material, in particular expanded clay or expandable slate.
  • a molded body made of a lightweight material known which has sound insulating properties is a liquid phase sintering of a mixture of a lightweight aggregate and a soda water glass.
  • the lightweight aggregate used are expanded glass, perlite and / or expanded clay.
  • the lightweight aggregate particles are connected to form a soda-lime glass with this network. It is proposed to use the shaped body as an acoustic panel, in particular as a baffle, for which, however, no further instructions are given.
  • the DE 100 20 955 A1 shows a shaped body which is formed exclusively of sintered together lightweight aggregates selected from expanded glass granules, expanded clay granules or thermally pre-expanded perlites.
  • the GB 1 444 331 A discloses a method of manufacturing an envelope-containing acoustic spacer according to the preamble of claim 13 and a soundproofing body, its integration into a soundproofing block, and a wall of soundproofing blocks on an inclined surface.
  • the soundproofing body itself consists of several layers, each containing spherical particles of different sizes.
  • the CH 565 909 A5 shows a ceiling construction with a formwork, a cavity and a space-facing surface heating element, which covers the formwork body.
  • Another object of the invention is to provide a concrete structure, in particular to provide a concrete floor, in which such a spacer is integrated and thereby has favorable acoustic properties.
  • the spacer not only fulfills the mechanical spacing function for the positioning of the reinforcement but also comprises a sound absorbing material to permanently influence the acoustic properties of the concrete structure in which the spacer is installed, ie to act as a sound absorbing element.
  • the spacer is preferably made of a glass-based, acoustically effective foam.
  • the spacer adjoins the formwork during manufacture of the concrete structure with at least one absorption surface, so that this absorption surface is exposed after removal of the formwork from the concrete structure and can absorb sound.
  • it is a mineral foam which may have high strength, such as a stone, brick or concrete block processed in construction.
  • the foam is surrounded by at least one surface portion of the foam, namely the absorption surface releasing envelope.
  • the foam has an angular structure in cross-section, in the simplest case a square or rectangular structure, the freed area section preferably corresponds to a total area which extends in cross-section from corner to corner.
  • This released absorption surface is then the surface which, when installed, faces outwards, i. is exposed to the acoustically influencing space.
  • the desired sound efficiency can be achieved particularly favorable by the foam.
  • the foam is replaced by another suitable sound absorbing material.
  • soft and possibly deformable materials e.g. Rock wool or mineral wool used for sound absorption.
  • the wrapper is cement based.
  • the sheath preferably has fiber portions, but the fiber portions may also be provided in the case of a sheath which is not cement-based.
  • the spacers according to the invention are installed in the concrete structure such that at least one outer surface of the spacer is exposed in the finished concrete floor.
  • spacers are connected by means of a surface element on which they are applied at a distance from one another.
  • This summary several spacers allows it to easily comply with desired distances, especially regular distances, between the spacers in the course of preparation, for example.
  • a concrete pavement or a precast concrete part In addition, they also allow easy handling, such as by unwinding the so summarized spacers.
  • the summary of a plurality of spacers by means of a surface element possibly also in one of the further embodiments, in particular of the surface element as described below, also has independent significance. In particular, regardless of whether the spacer is constructed on a glass-based, acoustically effective foam.
  • the surface element is a nonwoven, for example a cellulose-based nonwoven, or a cardboard or paper element.
  • the binder can be a hydraulic, also be hydraulically setting binder. It is preferably a binder based on cement or ceramic. It is also expedient if the binder has a fiber content. Last but not least, such a fiber content can ensure the possibly desired diffusion openness or support it. Also, the fiber content can contribute to the acoustic effectiveness.
  • the glass particles are preferably expanded glass granules which are compacted with the aid of the binder or else by a sintering process to form the acoustically effective foam.
  • the spacer according to the invention preferably has a rectangular or square, possibly also trapezoidal or triangular cross-section.
  • a cross-section forms a flat absorption surface, which can be integrated into the visible side or the outside of the concrete ceiling to be acoustically influenced.
  • this absorption surface is not flat, but is characterized by the structure of the spacer material.
  • the absorption surface which forms the visible side or is integrated into the outside of a concrete ceiling is also the surface which has no covering.
  • the absorption surface of the acoustically acting spacer is covered by a self-adhesive film or similar protective layer.
  • This protective layer protects the absorption surface from penetrating concrete sludge or other contaminants and can be removed after final completion of the structure.
  • Another object of the invention is a concrete structure, preferably a concrete floor, in which in at least one outer surface partially exposed spacer made of acoustically active foam are embedded, preferably of a glass-based acoustically active foam.
  • the spacers are exposed only in a direction parallel to the direction of extension of the concrete surface surface and specifically specifically only with an outer surface (namely, the absorption surface) of the spacer. Accordingly, viewed in cross-section, two or three further outer surfaces of the spacer in the concrete ceiling are covered by the concrete. Preferably, the faces of such a spacer are covered by concrete in the concrete floor. This overlap is also given by means of the already mentioned wrapping. The concrete then adheres to the outside of this enclosure.
  • the adhesion of such a spacer to the concrete can be achieved partially or exclusively by mechanical attachment or clawing of the unevenly textured surfaces of the spacer.
  • the spacer preferably has in its outer surfaces free-standing individual structures in the millimeter range, for example. In the size of 1 to 2 millimeters on. Integrated into an envelope, these may be spherical, glass-based or glass-like structures.
  • the acoustically effective area of the concrete structure can be further processed later with conventional techniques.
  • the area including the absorption surfaces of the spacers may be painted or coated with an open-pored plaster. It must be ensured that a coating remains acoustically transparent so that the sound absorbing properties of the absorption surfaces of the built-in spacers are maintained.
  • the glass-based acoustically-effective foam may be produced by conventional sintering techniques.
  • the wrapper can first be poured in a mold. Subsequently, the foam is placed in the freshly made wrapper and the wrapper is pressed in the not yet cured state to the inserted foam and fixed until the curing is done.
