Definitions
- the invention relates to a building and insulating material using small parts made of foamed plastic, such as expandable polystyrene (EPS).
- foamed plastic such as expandable polystyrene (EPS).
- So-called lightweight materials as they are used in a wide variety of ways today to improve thermal insulation, contain, apart from straw, wood wool and the like, organic light components in most cases in addition to concrete or corresponding binders as the actual lightweight material, elements made of foamed plastic, such as the one below foamed polystyrene known by the brand ST ⁇ ROPOR.
- foamed plastics are used for use in a building or insulating material either in the form of small balls, or in the form of shredded material in shredders, with parts made of foamed plastic, such as packaging or the like, which have already been used as the starting material , can be recycled.
- the major disadvantage of using foamed plastic in the form of small balls is the fact that the cohesion of the entire composite material is only relatively poor due to the shape of the plastic particles - as easily conceivable, these particles "run apart" without mutual support, so that If the spaces between the individual plastic spheres are completely closed by the adhesive or binder, the material obtained has the disadvantage of very poor water vapor permeability - the known foamed plastics laid in sheet form External thermal insulation of buildings can, for example, only have a layer thickness of approx. 4 cm, because the vapor barrier effect of the plate becomes so great that there are condensation phenomena with correspondingly serious disadvantages inside the wall to be insulated mmt.
- the tearing mechanisms used in known recycling techniques of such foamed plastics in turn have the disadvantage that the resulting snippets no longer have closed pores on the surface, so that water and the like can penetrate into the interior, which in the overall composite of the construction and insulation material has major disadvantages with regard to the Insulating effect and also with regard to bacterial infestation and the like.
- the object of the present invention is to avoid the disadvantages mentioned of the known building and insulating materials of the type described and to provide such a material which, in particular, improves the water vapor permeability with consistently good insulation and long-term durability guaranteed.
- the use of recycled foamed plastic should also be possible without any problems.
- this object is achieved in the case of a material of the type mentioned at the outset in that it has angular snippets of foamed plastic, such as, for example, poystyrene, which in turn have pores which are closed on all sides and are arranged adjacent to one another with the leaving of free spaces.
- foamed plastic such as, for example, poystyrene
- Such angular snippets can be produced, for example, similarly to that described in DE 25 16 461 A1, by moving or dropping correspondingly fusible, foamed plastic material through cutting grids with heated cutting wires staggered one behind the other, which results in certain sizes according to the mesh size after the last cutting grid of essentially cubic-shaped edged snippets, which have melted-on pores on all sides due to the melting process of the cutting wires. Since the thickness of the superficial enamel skin on such angular chips can easily be influenced via the cutting parameters (temperature, cutting speed, etc.), the corresponding properties of the chips obtained can easily be adapted to the respective requirements. Apart from, for example, new material in sheet form, plastic parts that have already been used once, for example as packaging, can also be recycled.
- these angular snippets can, for example, be introduced directly into the spaces to be filled, for example blown in, no further binding or strengthening being required.
- a further embodiment of the invention is advantageous for the most diverse purposes of using such building and insulating materials, according to which the snippets are superficially covered with adhesive, adhesive or binding material. are coated and brought together to the desired shape before it hardens.
- a wetting agent can initially be used in the production of such at least partially bound layers or molds, after which the angular snippets, for example, in a free-fall mixer with binder (cement and the like) and if necessary also add aggregates (sand and the like) and then bring them into the desired shape (for example wall layers, building blocks or the like) before these agents harden.
- the snippets preferably have an irregular size and / or shape, which can ensure a good thermal insulation effect with excellent water vapor diffusion.
- the building and insulating material according to the invention is preferably used as a building block or as a surface layer.
- the angular snippets have to be treated on the surface with appropriate binders as described above.
- the building block can be processed as usual (cut, laid, etc.). Apart from that, it would of course also be possible to manufacture strands with suitable machines.
- the material which is somehow bound or solidified at least on the surface of the respective layer can be used as described; if such surface layers are to be attached to substantially vertical walls (for example outer walls of houses or the like), the snippets are filled in a preferred embodiment of the invention before the adhesive, adhesive or binding agent cures behind a formwork spaced apart from the surface to be coated.
- Fastening elements such as dowel screws or the like provided with large holding surfaces, can be attached beforehand together with the formwork, with which the hardened vertical surface layer is securely held on the wall to be insulated after the formwork has been removed. With such insulating layers, unevenness in the wall can also be easily compensated for.
- the advantages according to the invention in which the construction and insulation material has a thermal insulation which is practically independent of the water vapor permeability, also come into play here again.
- FIG. 1 shows a schematic cross section through a device for producing snippets from foamed plastic for building and insulating material according to the present invention
- FIG. 2 shows as an example a single angular snip be made of foamed plastic for construction and insulation material according to the invention, produced for example in a device according to Fig. 1
- Fig. 3 shows various uses of the construction and insulation material according to the invention on a partially cut multi-storey house
- Fig. 4 shows a partial section through an outer wall with a vertical insulating layer made of building and insulating material according to the present invention
- FIG. 5 shows an example of a building corner set with building blocks made of building and insulating material according to the present invention.
- three cutting frames 2 are installed offset in height in the essentially upright shredding unit 1, the heating wires 3 of which are supplied with heating current in a manner not shown here and are thus heated.
- EPS expanded poystyrene
- These parts fall on the next cutting frame 2, whereby they come to lie relatively disordered and are further shredded; after passing through the third cutting frame 2, essentially cubic snippets 5 are formed - shown enlarged in FIG. 2.
- the size and shape of the snippets 5 can be influenced by the grid width or alignment of the cutting frame 2.
- the thickness and consistency of the resulting melt skin on the surface of the snippets 5 can be influenced particularly by the temperature of the heating wires 3.
- the chips 5 accumulating on the underside of the comminution device according to FIG. 1 in a collecting area 6 can be sucked off continuously or intermittently via a blower 7 and transported further via a line 8, the inlet side of this blower 7 being at a distance from the underside of the collecting area 6 here , so that the sucked-in air is not sucked through the entire cutting device.
- the snippets 5 made of foamed plastic, for example in the manner described, are angular and have pores which are closed on all sides, so that no water, no microorganisms or the like can penetrate the snippets 5.
- These snippets 5 are eminently suitable as building and insulating material, as can easily be seen, for example, from FIG. 3.
- a layer 10 of snippets 5 is filled between the latter and the surrounding soil, which serves to isolate and dry this area.
- Standing surface layers 14 are arranged on the outer wall 12 of the building and on the inner wall 13 of the basement and attic, the manufacture of which is explained in more detail in relation to FIG. 4, and which consist of snippets 5 which are superficial with adhesive, adhesive or binder have been encased and filled before being hardened behind a formwork spaced apart from the surface to be coated.
- these layers could also consist of pre-assembled plates, for example brought together with tongue and groove, which in turn are suitably constructed from material according to the present invention.
- unbound layers of snippets 5 are provided behind appropriate cladding.
- the floors 17 are each provided with at least partially unbound corresponding layers which are superficially covered, for example, with tread plates or can also have thin screed layers or the like.
- the essential advantage of the material according to the invention comes into play that the layer thickness can be easily increased to increase the thermal insulation without the water vapor diffusion through the layer being significantly impaired or worsened thereby.
- 4 shows an example of the production of a surface layer with material according to the present invention on essentially vertical walls.
- dowels 18 are placed in the unplastered wall 19, into which longer screws with large washers are screwed.
- Formwork beams 20, which can extend over two to four grid fields and are, for example, one grid field wide, are mounted on the outside in the intended layer thickness spacing. Window and door recesses are attached to the formwork panels 20 in a manner that cannot be seen here by means of lost or removable frames.
- the snippets 5 are encased in a free-fall or compulsory mixer with binder (wall binder plus sand, cement plus sand and additives, or the like) and water and then filled behind the formwork beam 20. After setting, the formwork can be removed, the resulting layer being held securely to the wall by means of the dowels 18. The finished insulating layer can then be reinforced and plastered in a known manner if desired.
- FIG. 5 shows the use of building blocks 21, which are produced in a known manner by filling angular snippets 5 coated on the surface with adhesive, adhesive or binding agent into corresponding shapes.
- the spaces in the building blocks 21 can be filled with concrete or the like for a number of rows arranged one above the other, provided with reinforcing irons, cable ducts or the like, or can also be left empty in certain areas.
- the material of the block 21 in turn brings the advantages of the invention which have already been mentioned several times - the thickness can be used to select the thermal insulation which is independent of the water vapor permeability determined via the remaining channels between the angular snippets.
