Definitions

• the invention relates to an edge insulation strip for separating the edges of heated, floating floors from the wall in buildings.
• a distance is known to be provided between the edges of the floor and the wall.
• Edge insulation strip used for insertion, the originally flat edge insulation strips are bent in an L-shape, 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 floor or an underlying layer of insulating material and the top of the supporting floor is arranged.
• Known edge insulation strips consist of impregnated corrugated cardboard strips or covered with a wax layer, which strips are inserted between the floor and the wall in this way.
• corrugations run vertically on the respective wall, which corrugated cardboard strips are perforated along a line perpendicular to the corrugations, so that a section of the corrugated cardboard strip can be folded over to assume the L-shape mentioned above.
• 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 both known 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 vertical 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. If the floating floor thus expands, the edge insulation strip cannot be pressed together at the blocked areas, so that cracks occur again. Waste that has fallen into the troughs can also cause hygienic problems. Furthermore, the corrugated cardboard used for the production of the known edge insulation strips, e.g. quality class "B 3" of DIN standard 4102, i.e. it is simply flammable. However, quality class "B 2", normally flammable, is desirable. Finally, the production of a laminate consisting of a corrugated cardboard and associated plastic strips is obviously a rather expensive process.
• the aim of the invention is to remedy the disadvantages mentioned.
• the edge insulation strip according to the invention is through characterized the features of 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.
• 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 manufacturing process for edge insulation strips
• FIG. 3 shows a section through a back part of a room with inserted edge insulation strips
• FIG. 1 shows a diagrammatic view of an embodiment of the edge insulation strip according to the invention.
• This edge insulation strip is a one-piece component which is made of a flexible plastic and can optionally have various additives, for example color pigments, fillers, fire-retardant substances, etc.
• the plastic is a closed-cell polyolefin foam, for example foamed polyethylene or a foamed, cross-linked polyethylene or a pillarpori ⁇ ger 'polyvinylchloride. Open-pore foamed materials can also be used, but closed-pore foamed plastics are preferred because their thermal insulation and also sound insulation are better.
• the edge insulation strip shown in FIG. 1 has a first, flat side 1. On the side opposite this flat surface 1, two parallel longitudinal surface sections can be distinguished, namely a first longitudinal surface section 2, which has shafts 8 which run in the longitudinal direction of the strip, and a second longitudinal surface section 3, which has a flat longitudinal surface section forms, which runs parallel to the first, flat page 1.
• the strip is thus composed of a longitudinal section 4, which is flat on both sides, and a longitudinal section 5 directly adjoining it, one side of which is profiled by the shafts 8.
• This incision 9 of this embodiment facilitates to a certain extent the folding of the strip shown in FIG. 1 into the L-shape, as shown in FIG. 3, in which form the edge insulation strip is used
• the dimension of the thickness 6 of the longitudinal section 4, which is flat on both sides is equal to the distance 7 measured between the deepest point of a respective wave trough, which is described by the waves 8, and the first flat side 1.
• the dimension of the thickness 6 of the longitudinal section 4, which is flat on both sides is the same size as the shaft height 10 of the shafts 8.
• the distance 19 between the apex of a respective shaft 8 and the first flat side 1 is selected such that it is twice the thickness 6 of the longitudinal section 4 which is flat on both sides.
• the strip is advantageously made of a polyethylene foam which corresponds to quality class "B 2" according to DIN 4102. This grade of polyethylene foam is commercially available from various manufacturers.
• a manufacturing method of the edge insulation strip will now be explained with reference to FIG. 2. It is generally known that plastics which are in the form of long strips and in the foamed state can be cut horizontally by means of a profile cutting machine in order to produce plastic strips which have at least one particularly profiled side.
• a strip 11 is assumed which has a rectangular cross-sectional shape, as shown in FIG. 2. If this starting strip 11 is cut by means of a profile cutting machine, two blanks, two raw strips 13, 14 are formed. In order to further form the second, flat, longitudinal surface section 3, a number of shafts 15 and 16 are cut away on each side of the two blanks 13, 14. The section lines are indicated in FIG. 2 by reference numbers 20 and 21. Comparing FIG. 2 with FIG. 1, it can be seen that the lower, cut-off part of the strip 11 is identical to the strip shown in FIG. 1, an upper part being present on the lower part, which again is identical to the strip shown in FIG. 1 but rotated by 180 °.
• Fig. 3 shows in section a load-bearing floor 22 and a wall 18 of a building standing thereon drawn on which the heated, floating floor 17.
• this floating floor 17 can contain lines 25 of the underfloor heating system, for example, the edge insulation strip is now inserted in such a way that the corrugated longitudinal section 5 in the space between the edge of the floating floor 17 of the wall 18 is arranged and the section 4 which is flat on both sides is arranged under the insulating layer 23. It is important here that the waves of this edge insulation strip run horizontally and not vertically, as is the case with the known edge insulation strips. Consequently, the top wave acts as a seal and prevents any foreign matter from accidentally falling into the empty space of the wave troughs. This not only prevents that thermal expansion of the floating floor 17 is prevented, but also that it is not possible for substances which produce hygienic problems to enter the space mentioned.
• OMPI can penetrate.
• the profiling of the edge insulation strip shown in the above figures consists of waves which are approximately sinusoidal in cross section. However, a wide variety of waveforms are provided, some of which are shown, for example, in FIGS. 4, 5 and 6.
• edge insulation strip described for example, namely that a foam pipe strip is cut according to the description, should not be taken as a limitation.
• the edge insulation strips described can also be produced by means of extrusion or by means of thermoforming processes.
