Definitions

  • the present invention relates to composite elements for heat or sound insulation of buildings.
  • the known hollow bricks can be used to insulate the outer and also the inner walls of buildings in view of the above.
  • hollow tiles have to be shaped using special shapes and then baked.
  • Hollow concrete bricks can also only be produced with the help of special molds and usually have an open area.
  • Hollow concrete bricks are not easy to attach to existing facades, unless they have sufficient load-bearing capacity and thus represent a second wall, so to speak, that is attached to an existing facade.
  • Boards made of pressed wood shavings or fibers with admixtures of inorganic oxides are relatively easily accessible and easy-to-install insulators, but they have increasing production costs due to the increase in energy costs. The same applies to a greater extent to sheets made of organic foams such as polystyrene or polyurethane.
  • Such insulators which are used in the form of plates, also require cladding on both sides, since the plates normally have no surface protection and are sensitive to moisture and mechanical stress.
  • the applicant has described in her LU 81.739 a method which, on the one hand, allows flexible insulators, for example in the form of matted slag or glass wool mats or rigid organic foam sheets, to impart effective surface protection without impairing their insulating properties and on the other hand providing them with one to convey sufficient mechanical strength, which makes it possible to dispense with complicated brackets and cladding during installation.
  • This method provides for porous flexible mats or pressed panels to impart surface protection by covering the surfaces of the mats or panels with a colloidal cement mortar consisting of cement and a just sufficient amount of water, which may also contain additives Spray coated.
  • the insulating elements obtained in this way are, however, relatively heavy and therefore cannot be attached to walls without the aid of intensively acting adhesives, or must be applied uncoated and only coated with colloidal cement mortar after application.
  • the aim of the invention is to propose insulating composite elements which avoid the use of expensive starting materials and which have a very low density.
  • a full or hollow base body consisting of a cellulose-based material, for example cardboard, has an adhesive layer made of a colloidal cement mortar consisting of cement and water.
  • the idea on which the invention is based is based on the surprising finding that conventional, pressed or vacuum-produced cardboard can be coated with colloidal cement-water mixtures and that when the colloidal mixture hardens it forms a real adhesive bond between the inorganic phase and the substrate comes on a cellulose basis.
  • Coating the cardboard bodies with colloidal concrete is conventional in e.g. feasible by spraying.
  • the colloidal concrete used is preferably a material made from cement and water, as described by the applicant in its LU 79.486.
  • the colloidal concrete will preferably be reinforced with glass fibers, which can be added to the concrete during the spraying.
  • the colloidal concrete will be provided with organic additives such as sawdust in accordance with the method described by the applicant in its LU 82.862.
  • organic additives such as sawdust in accordance with the method described by the applicant in its LU 82.862.
  • the composite elements according to the invention become practically impermeable to water if the colloidal concrete is provided with additives such as 0.1-2% water glass.
  • cardboard shells can form a hollow body of suitable geometry, the outer surfaces of which have the adhesive layer made of colloidal concrete.
  • conventionally pressed cardboard, or cardboard produced by suction can easily be converted into closed and open forms.
  • cardboard packaging for fragile foods or for drinks in bottles are known to offer excellent protection, the packaging being precisely adapted to the shape of the goods.
  • At least one cardboard board has at least one of its surfaces the adhesive layer made of colloidal concrete, which also covers the edge surfaces.
  • FIG. 1 shows cross sections through 2 cardboard cardboard trays that are nested, while FIG. 2 shows a hollow body produced by nesting before being coated with colloidal concrete and FIG. 3 shows a top view of the hollow body; 4 shows a section through a wall which is insulated by means of the hollow body according to the invention.
  • Fig. 5 shows a composite panel in which a one-piece corrugated board has a double-sided coating with colloidal concrete;
  • FIG. 6 shows a composite plate in which the corrugated cardboard is designed twice, while in FIG. 7 a composite plate is shown which understands two adjacent corrugated cardboard plates with a common cover made of colloidal concrete.
  • Fig. 1 shows the upper and lower shells (1 and 2) which are nested. 2 shows the body before the concrete layer is sprayed on.
  • the preferred geometric shape shown here proves to be extraordinarily favorable with regard to the attachment of the composite elements to walls.
  • the bodies are connected to the wall via their surfaces (A) or (B) and to one another via their surfaces (F), additional cavities (20) being formed as shown in FIG. 4, which reinforce the insulating effect .
  • the finished body is given a glaze or a varnish coating, or that the colloidal concrete used can be provided with dyes before spraying, means that the construction specialist has access to aesthetic, effective and inexpensive components with the composite elements according to the invention Help both new and existing structures can be embellished on the outside and inside and at the same time insulated against heat and noise.
  • Fig. 5 you can see the cardboard board, which consists of 2 straight plates (11 and 12), between which there is a corrugated cardboard film (10). Of course, plates can also be used that have a completely different structure. Each of the plates (11 and 12) is connected to an adhesive layer (14 or 15) made of colloidal concrete.
  • Fig. 6 shows a structure consisting of a cardboard construction that understands 2 outer plates (11 and 13) and a central plate (12); between the plates (11 and 12) and (12 and 13) there is a corrugated film (10 and 16).
  • both outer plates (11 and 13) each have an adhesive layer (14 or 15) made of colloidal concrete.
  • FIG. 7 shows a composite panel comprehensively 2 adjacent corrugated cardboard panels, each of which has a structure according to FIG. 5, namely 2 cardboard panels, each surrounding a corrugated film.
  • the plates (11 and 11a) lie against each other, while the plates (12 and 12a) are coated with colloidal concrete, the Concrete layer (14) also covered the edge surfaces of the plates.
  • a composite panel, as shown in FIG. 7, can easily be used for the internal and external insulation of all types of structures.
  • the cardboard base will suitably be a base plate made by a suction process, which will be brought into the desired shape and coated with colloidal concrete.
