An insulating edge member with the continuous flat side of the insulating edge member facing the floating floor, the contoured surface of the insulating edge member facing the wall, and a thin flat longitudinal section bent over the supporting floor. A method for using a heat insulating edge member, which is characterized by filling the gap between a wall and a floating floor with the heat insulating edge member.

Description The present invention relates to an insulating edge member for separating the edge and wall of a floating floor, particularly a heated floating floor.

For several years, it has become common, especially in new buildings, for heating to be provided by conduits placed in the floor. When comparing whether this so-called floor heating system has a uniform heating effect compared to heating equipment placed in a recess in the wall below the window,
It has special advantages and requires less thermal energy than conventional heating methods.

In order for a heated floating floor to freely expand thermally in a room equipped with a so-called floor heating system, a space is required between the edge of the floating floor and the wall.

If a heated floating floor were in contact with or tightly joined to the walls of the corresponding room, the walls would be stressed and cracked due to thermal expansion and contraction. There is also the possibility of damage to the conduit system within the floor.

However, expansion joints with openings generally cannot be used. This is because if the open portion is blocked by a foreign object or the like, the floating floor will come into contact with the wall through the foreign object or the like. In order to prevent the blockage of this opening, flexible structures, so-called insulating edges, are used in the space between the floating floor and the wall.

Typically, an originally flat insulating edge is bent into an L-shape, with its vertical leg placed between the heated floating floor and the wall, and the other short leg placed below or below the heated floating floor. It is sometimes placed between the underlying insulation layer and the upper side of the building's supporting floor.

The conventional edge members used hitherto consist of a piece of impregnated or waxed corrugated cardboard mounted between the wall and the floor, the corrugated section extending vertically along the wall. The corrugated cardboard strip has perforated lines extending perpendicular to its corrugated surface, and a portion of the corrugated cardboard can be folded to create the L-shape described above.

Laminate edge seals are also known. It consists of a corrugated piece of cardboard with a layer of foamed plastic material. The foamed plastic material provides the edge member with thermal and acoustic insulation properties. In particular, the transmission of impact sound from the sides is reduced.

A common drawback of both edge members is that the corrugated surface extends vertically along the wall. Foreign objects, such as small particulate building materials, can fall into the vertically extending open spaces of the corrugated surface and become clogged. Such clogging reduces the flexibility of the edge member. When the floating floor expands due to heating, the edge members cannot be pushed together at this location and cannot absorb the thermal expansion of the floating floor. Stresses arise between the wall and the floor or under the floor, which must be avoided by means of edge members. Additionally, debris between the corrugated surfaces is a hygiene problem.

Furthermore, the cardboard used to make the known edge members is defined according to DIN standard 4102 as class B3, ie easily combustible. However, it is desirable to have B2 class, that is, to have normal flammability or non-flammability. Finally, the production of laminates consisting of cardboard and laminated layers of plastic material is quite expensive.

The object of the invention is to provide an insulating rim that does not have the disadvantages of known materials and can be manufactured more cost-effectively than known rims for filling spaces between walls and floating floors.

This purpose consists of two different longitudinal sections 4, 5 made of flexible plastic material and extending parallel to the longitudinal direction, a first longitudinal section 5
one surface of has a longitudinal wavy contour 8;
Its opposite surface 1 is flat, the second longitudinal section 4 has a flat surface 3 on both sides, and the thickness 6 of the second longitudinal section 4 is equal to that of the first longitudinal section. 5, one flat surface of the second longitudinal section 4 is thinner than the thickness 19 of the first longitudinal section 5.
This is achieved by providing an insulating edge member with a contoured surface characterized by being coplanar with the flat surface 1 of the material and creating a continuous surface.

Preferred embodiments of the invention are described in the embodiment section of the claims.

The invention also includes a method of manufacturing the insulating edge member and its use for edge-to-wall separation of a floating floor in a building, preferably for a heated floating floor. The space between the wall and the floating floor is filled, the flat surface of the insulating edge member faces the floating floor, the contoured surface of the first longitudinal section faces the wall, and both sides are flat. The second longitudinal section is placed on a support bed.

In a preferred embodiment of the invention, the second longitudinal thickness, which is flat on both sides, is between the lowest point of the respective undulating profile and the opposite side of the first longitudinal section with the undulating surface. Corresponds to the distance between flat surfaces.

Preferably, at the transition point between the first longitudinal section and the second longitudinal section, a notch is provided on the side with the corrugated surface and extends in the longitudinal direction of the insulating edge member. This makes it easy to bend the longitudinal portion into an L-shape.

It is particularly preferred that the contour height of the first longitudinal section corresponds to the thickness of the second longitudinal section, which is flat on both sides.

The insulating edge member of the present invention is an integral element and is made from a flexible plastic material. In order to obtain sufficient flexibility, a foamed plastic material, preferably a closed cell foam, is used for the insulating edge member. Various additives can be included in the foam, such as pigments, fillers, flame retardants. The inclusion of flame retardants is particularly suitable. This is because such a heat insulating edge member can obtain good quality in terms of flame retardancy according to the DIN 4102 method. The addition of flame retardants is limited by the fact that the flexibility of the insulating edge member must not be reduced to the extent that the insulating edge member is unable to perform its function of absorbing the thermal expansion of the floating floor.

The plastic material is a closed cell polyolefin foam, such as expanded polyethylene, or expanded crosslinked polyethylene, or closed cell polyvinylidene chloride. However, materials other than such foamable plastics can also be used. Although open cell foams can generally be used, closed cell foams are preferred due to their good thermal and acoustic insulation properties. Open cell plastic materials are not suitable as they are, as they are permeable to water. However, in the case of open cell polyethylene foam, the flat surface of the insulating edge member is covered with a foil or layer impermeable to liquids. Such coated surface of the insulating edge member contacts the floating floor. In order to prevent the penetration of water into the insulating edge member, especially from freshly poured concrete, it is useful to use a water-impermeable barrier layer on such side of the insulating edge member. .

Closed cell foam insulating edges do not require such barrier layers.

The final insulating edge member must have a sufficiently low compressive strength to avoid high stress generation due to thermal expansion of the floor, but this compressive strength is limited to the horizontal static position of the newly created floor. It must have a value high enough to withstand the load.
Those skilled in the art will determine the optimal choice of profile for the insulating edge member of the present invention, depending on the physical properties of the foam material selected, the architectural requirements of the particular job, and the processing equipment available. could be done easily.

Preferably the insulating edge member is made from polyethylene foam meeting the standard of DIN 4102. Such foams are commercially available from several companies.

Since the wavy top contour of the insulating edge acts as a seal against the wall, the cavity is closed at the top and no foreign material is trapped in the trough of the contour between the insulating edge and the wall. will not fall. These insulating edge members can be manufactured very inexpensively using known equipment.

The insulating edge member according to the invention can be manufactured by longitudinally cutting thick pieces of raw material. However, the insulating edge member according to the invention can also be made by extrusion or thermoforming.

The present invention will now be described in detail with reference to the accompanying drawings.

FIG. 1 shows a perspective view of a preferred embodiment of the insulating edge member of the present invention, and FIG. 2 shows a method of manufacturing the insulating edge member.
FIG. 3 shows a cross-section of a piece of foamed plastic raw material before cutting; FIG. 3 shows a cross-section of the edge of a room with a heated floating floor and an insulating edge; FIGS. 4 to 6: FIG. 7 is a partial cross-sectional view of an insulating edge showing another possible implementation of the insulating edge with a different wavy profile;

FIG. 1 is a perspective view of a preferred embodiment of the insulating edge member of the present invention. The planar surface 1 of the first longitudinal section is the underside of the internally placed insulating edge member;
Therefore, it is in direct contact with the floor. The opposite surface of the insulating edge member has two distinct portions. 1st
The longitudinal part 5 of has an undulating contour 2, the undulating contour running in the longitudinal direction. Parallel to the first longitudinal section 5 there is a second longitudinal section 4 with a flat surface 3 . At the border between the first longitudinal section 5 and the second longitudinal section 4,
There is a longitudinal cut between faces 2 and 3, which starts from these faces and extends approximately half the thickness 6 of the insulating edge. The notches 9 facilitate longitudinal bending of the insulating edge member into an L-shape and gluing. The thickness of the second longitudinal section 4, which is flat on both sides, is the distance between the trough of the wavy contour of the first longitudinal section 5 and the lower surface 1 of the insulating edge member. is preferred. In the embodiment shown in FIG.
corresponds to the thickness 6 of the second longitudinal section 4 which is flat on both sides. In other words, the distance 19 between the crest of the wavy contour 8 and the flat surface 1 is twice the thickness 6 of the first longitudinal section 4 which is flat on both sides.

The size of the insulating edge member shown in FIG. 1 is selected with consideration to the ease with which the insulating edge member can be fabricated using conventional equipment and the mechanical strength and flexibility of the insulating edge member.

Next, a method of manufacturing the heat insulating edge member will be explained with reference to FIG.

It is known that plastics material, which is generally present in long strips in a foamed state, can be cut horizontally with a contour cutting machine to produce parts of plastics material having at least one specific contour.

In order to make the heat insulating edge member of the present invention, a raw material piece 1 having a rectangular cross section as shown in FIG.
Use 1. When this raw material piece 11 is fed to a contour cutting machine, two cut parts 13, 14 for the insulation edge part are obtained. To form the second longitudinal section 4 with a flat surface, a number of corrugations 15 or 16 are cut out at the edges of the two cut parts 13, 14. This creates a second longitudinal section that is flat on both sides and has the desired width. The cutting lines are at numbers 20 and 21 in FIG. Figures 1 and 2
Comparing the figures, the lower section 13 of the piece 11, minus the multiple wavy contours 15, is the same as the insulating edge member of FIG.
It can be seen that the upper cut-away member 14 minus the multiple undulating contours 16 is also identical to the insulating edge member of FIG. 1, but rotated 180°. The thickness of the raw material piece 11 need not be twice the maximum thickness 19 of the insulating edge member to be made. It is important that the thickness of the raw material piece 11 may be twice the maximum thickness of the insulating edge piece, reduced by the height 10 of the wavy profile. The thickness of the raw material piece therefore only needs to be three times that of the second longitudinal section 5 which is flat on both sides.

This allows considerable savings in raw material costs.

If open-pore foam is used, the insulating edge member is laminated with a water-impermeable film after manufacture. If the insulating edge member is made by extrusion, the impermeable layer can also be formed by coextrusion. Generally closed cell foams can also be provided with a barrier layer.

Figure 3 shows how the heat insulating edge member is installed between the wall and the floor. Figure 3 shows the supporting floor 2 of the building.
3 and the associated wall 18 of the building are shown. Also shown is the insulation layer 23 and the heated floating floor 17 above it. This insulation method is typical for underfloor heating. Floating bed 17 includes conduits 25 for heating the bed. The insulating edge member of the present invention is installed in the space between the wall 18 and the floating floor 17. A first longitudinal section 5 with a wavy contour of the insulation edge member is arranged in the space between the floating floor 17 and the wall 18, and a second longitudinal section 4, flat on both sides, lies below the insulation layer 23. will be placed in What is important is that the wavy contour 8 of the insulating edge extends horizontally and not vertically as in known insulating edges. The top wavy profile acts as a seal to prevent foreign objects from accidentally falling into the trough gaps of the wavy profile. The insulating edge member of the present invention not only allows for thermal expansion of the floating floor, but also prevents the ingress of unsanitary substances.

The wavy profile of the insulating edge member shown in FIGS. 1-3 is approximately sinusoidal. However, various contours are possible, some of which are shown in FIGS. 4-6.

FIG. 4 shows that the wavy profile of the central longitudinal section is rectangular.

FIG. 5 shows that the wavy profile of the central longitudinal section is sinuous.

FIG. 6 shows that the wavy profile of the central longitudinal section is zigzag-shaped.

In all cases, the height of the contour 10 for the distance 7 between the trough of the wavy contour and the surface 1
is selected to provide sufficient mechanical strength to the insulating edge member.

The heat insulating edge member of the present invention has a width of, for example, 195 mm,
The second longitudinal section, which is flat on both sides, has a width of 35 mm;
The width of the first longitudinal section with a wavy contour is
It is 160mm. The thickness of the second longitudinal section, which is flat on both sides, is 4 mm. The height of the contour is 4 mm and the thickness of the first longitudinal section with the contour is 8 mm including the contour. The length of the insulating edge is several meters, so one insulating edge is usually sufficient for one edge of the room.
