Definitions

• the invention relates to an edge insulation strip for separating the edges of heated, floating floors from the wall in buildings.
• edge insulation strip As is known, a flexible component, a so-called edge insulation strip, is used in the space prevailing between the floor and the wall.
• edge insulation strips which originally run flat, are bent in an L-shaped manner, the vertical leg of the L-shape then being between the edge of the heated, floating floor and the wall, and the other, shorter leg between the underside of the heated one floating bottom or an underlying insulating layer and the top of the load-bearing bottom is arranged.
• Known edge insulation strips consist of
• edge insulation strips are laminated bodies and consist of a corrugated cardboard strip which has been treated as mentioned above and on which a foamed plastic is applied.
• the foamed plastic has the effect that the edge insulation strip is thermally and acoustically insulated, including a reduction in the lateral transmission of sound resulting from impacts.
• a common disadvantage of the two edge insulation strips described above is that they are designed in such a way that the waves extend vertically along the respective wall. Foreign bodies, for example construction waste, can very easily fall into the vertically extending wave troughs, which can lead to clogging at various points in the wave troughs. Such a blockage affects the flexibility of the edge insulation strips.
• the edge insulation strip cannot be pressed together at the blocked point, so that cracks occur again.
• waste that has fallen into the wave valleys can also cause hygienic problems.
• the corrugated cardboard used to manufacture the known edge insulation strips corresponds e.g. quality class "B 3" of DIN standard 4102 ,. i.e. it is simply flammable.
• quality class "B 2" normally flammable, is desirable.
• the aim of the invention is to parts to fix.
• the edge insulation strip according to the invention is characterized by the features of patent claim 1.
• top wave of the profiling can act as a seal against the wall, it is not possible for waste materials to penetrate into troughs between the edge insulation strip and the wall. Furthermore, these edge insulation strips can be produced in an extremely cost-saving manner using known machines.
• the subject of the invention is explained in more detail below with reference to the drawings, for example. It tends:
• FIG. 1 shows a diagrammatic representation of an embodiment of the edge insulation strip according to the invention
• FIG. 2 shows a section through a strip-shaped blank made of foamed plastic to illustrate a production method for edge insulation strips
• Fig. 3 shows a section through a corner of a room with inserted edge insulation strips
• Fig. 4 to 6 simplified sections through others
• Stripes This Randdämm- is an integral part which is made from a flexible foamed plastic and can optionally contain ver ⁇ various additives, for example pigments, fillers, fire retardants, etc.
• the plastic may be for example a closed-cell polyolefin ⁇ foamable be, for example, a foamed polyethylene or a foamed, cross-linked polyethylene or a closed-pore polyvinyl chloride foam. Open-pore foams can also be used, but closed-pore foams are preferred because they provide excellent thermal insulation and also an excellent CTE
• OMPI Provide sound absorption.
• Open-pore foams can be disadvantageous for this application in certain cases because liquid, water, can easily penetrate.
• the flat side of the strip can be provided with a water-impermeable film or a water-impermeable coating, so that water, which can be released in particular when freshly introduced concrete, cannot penetrate.
• the edge insulation strip shown in FIG. 1 has a lower first, flat side 1. The side opposite this is divided into three individual parallel longitudinal surface sections directly adjoining one another, starting according to FIG.
• the one-piece edge insulation strip consists of a central, wavy, profiled longitudinal section 5 which is delimited on both sides by a first 6 or second 7 longitudinal section which is flat on both sides.
• This incision 26 permits the strip to be bent in an L-shape, so that it takes the ready-to-install form shown in FIG. 3.
• the dimensions of the edge insulation strip shown in FIG. 1 are to simplify its manufacture on conventional machines and corresponding to the mechanical requirements placed on the edge insulation strips.
• the built-in edge insulation strip must have a compressive strength that is so deep that no high stresses occur due to the expected thermal expansion of the floor and, on the other hand, must be high enough that the edge insulation strip is subjected to a force of the freshly produced ( cast) floor can withstand.
• the person skilled in the art will simply be able to choose an optimal choice of the strip profile, depending on the physical properties of the particular foam selected, on the architectural requirements of the respective part of the building and on the available manufacturing machines and apparatus.
• the thickness 9 of the first flat longitudinal section 6 has a dimension which is equal to the distance 10 between the lowest point of a respective wave trough of the waves 8 from the flat side 1.
• the extent of the thickness 11 of the second longitudinal section 7, which is flat on both sides, is equal to that of the distance 14 between the apex 13 of a respective shaft 8 and the flat side 1.
• the measure of the thickness 9 of the first longitudinal section 6, which is flat on both sides is equal to the extent of the The height 15 of the shafts 8, the wavy profiled longitudinal section 5, and the extent of the thickness 11 of the second longitudinal section 7, which is flat on both sides, is twice as large as the extent of the thickness 9 of the first longitudinal section 6, which is located on the left and planar, as shown further below is, the selection of the various dimensions described allows a cost-saving manufacturing process of the edge insulation strip.
• the strip is preferably made of a foamed polyethylene which corresponds to quality class "B 2" according to DIN 4102. Such a polyethylene foam is commercially available from various manufacturers.
• OMPI Plastic strip or plastic pieces which have a profiled surface at one side are, for example, provided by means of profile cutting machinery manufacturers'.
• FIG. 2 For the production of edge insulation strip is believed 16 strips of fabric from a Kunststoff ⁇ having the selected physikali ⁇ rule "properties and a rectangular Quer ⁇ shows sectional shape according to FIG. 2. In this Ausry ⁇ tion, the extent of the thickness 19 of the réellestrei- fens 16 only about three times the size of the wave height 15 of the waves 8 (see FIG. 1).
• This output strip 16 is now cut by means of the machine in such a way that two identical edge insulation strips 20, 21 are produced, for which purpose only one cut 22 is necessary It can be seen that the lower cut
• FIG. 3 shows, in a simplified manner, a side wall 18 and the load-bearing floor 22 of a corner part of a room in a building. Furthermore, the known insulating layer 24 is shown and the heated, floating floor 17 lying above it. This floating floor 17 can contain lines 25 of a floor heating system, for example. The components shown and their installation position are known.
• the longitudinal section 7 will even have its effect if its exposed edge is somewhat damaged during the known rough construction work, parts of the same can be knocked off and nevertheless a perfect seal in the space between the floating floor 17 and the Maintain sidewall. This ensures that not only thermal expansion of the floating floor 17 is absorbed by the edge insulation strip, but also "that there is no blocking of the expanding floating floor 17 and thus generation of tension, and the penetration is also hygienic harmful substances safely prevented.
• the shafts 8 of the designs shown in FIGS. 1 to 3 are approximately sinusoidal in cross section. However, it is provided that the waveform can be borrowed in accordance with the designs shown in FIGS. 4 to 6, for example depending on the selected material and the intended use of the edge insulation strip.
• edge insulation strip has been explained in connection with the cutting of a foamed, plate-shaped plastic blank, the scope is not limited to this manufacturing process.
• edge insulation strips described can be produced by extrusion or by means of a thermoforming process.
