How to use edge members.

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.

Laminated edge seals are 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.

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

This purpose consists of a flexible plastic material comprising three different longitudinal sections 5, 6, 7 extending parallel to the longitudinal direction, the surface of the central longitudinal section 5 having a longitudinally corrugated surface. The central longitudinal section 5 has a contour 8, the opposite surface 1 is flat, and the two longitudinal sections located on each side of the central longitudinal section 5 have surfaces 3, 4 that are flat on both sides. , the thickness 9 of the first longitudinal section 6 which is flat on both sides is less than the thickness 14 of the central longitudinal section 5 and the thickness 14 of the second longitudinal section 7 which is flat on the other side. The thickness 11 is no greater than the thickness of the contoured central longitudinal section 5, the flat surface of the central longitudinal section 5 being flush with the adjacent surfaces of the outer longitudinal sections 6, 7. This is accomplished by providing an insulating edge member having a contoured surface that is located within.

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

The present invention also includes a method of manufacturing the insulating edge member and its use for separating floating floors and edges and walls of buildings, preferably for heated floating floors. i.e. the space between the wall and the floating floor is filled, the continuous flat surface of the insulating edge member faces the floating floor, the contoured surface of the central longitudinal section faces the wall, and both sides The flat, thin longitudinal sections are placed regularly on a support bed. A thick longitudinal section, flat on both sides, seals the space between the upper wall of the contour and the floating floor.

In a preferred embodiment of the invention, the thickness of the first longitudinal section, which is flat on both sides, is the opposite of the lowest point of the undulating surfaces of the individual trough-shape and the central longitudinal section with the undulating surface. The thickness of the second longitudinal section, which is flat on both sides, corresponds to the distance between the side planar surfaces and the thickness of the central longitudinal section.

In a particularly preferred embodiment, the height of the profile of the central longitudinal section corresponds to the thickness of the first longitudinal section which is flat on both sides.

Preferably between the central longitudinal section and the first flat-sided longitudinal section having a thickness less than the second flat-sided longitudinal section there is a central longitudinal section. An incision is made on the side with the wavy surface of the section, the incision extending in the longitudinal direction of the central longitudinal section and extending along the length of the longitudinal section L.
This makes it easy to bend into shapes.

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 barrier 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.

a second flat-sided longitudinal section having a thickness no greater than the thickness of the undulating longitudinal section;
Preferably having the same thickness as the undulating longitudinal section, its second longitudinal section seals the cavity together with the uppermost undulating profile, so that this cavity It is impossible for foreign objects to fall into the undulating troughs of the contour. Furthermore, these insulating edge members can be manufactured very inexpensively due to known techniques.

The insulating edge member according to the invention can be produced by longitudinally cutting sections of thick 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 flat surface 1 is the underside of the inner insulating edge member and is in direct contact with the floor. The opposite surface of the insulating edge member has three distinct sections. The central longitudinal section 5 has an undulating contour 2, the undulating contour running in the longitudinal direction. Parallel to said longitudinal section 5 two further longitudinal sections 6, 7 having flat surfaces 3, 4
There is. At the border between the central longitudinal section 5 and the first longitudinal section 6 which is flat on both sides, there is a longitudinal incision at the transition point between surfaces 2 and 3; begins at the surface and extends approximately half the thickness 9 of the insulating edge member. The notch 26 facilitates installation by bending the insulating edge member longitudinally into an L-shape. The thickness of the first longitudinal section 6 which is flat on both sides is preferably the distance between the wavy trough of the central longitudinal section 5 and the flat lower surface 1 of that section. . In the embodiment shown in FIG. 1, the height 15 of the wavy contour 8 corresponds to the thickness 9 of the first longitudinal section 6 which is flat on both sides. In other words, the distance 14 between the top of the wavy profile 8 and the flat lower surface 1 is twice the thickness 9 of the first longitudinal section 6 which is flat on both sides.

On the other side of the central longitudinal section 5 there is a second longitudinal section 7 with flat surfaces 4 on both sides.

The thickness of the second longitudinal section, which is flat on both sides, is
It corresponds to the distance 14 between the crest 13 of the wavy profile and the flat lower surface 1 in the central longitudinal section 5 . The thickness 11 of the second longitudinal section 7, which is flat on both sides, is as shown on the left side of FIG.
It is twice the thickness of the first longitudinal section 6 with flat surfaces on both sides.

The size of the insulating edge member shown in FIG. 1 is chosen to take into account the ease with which the insulating edge member can be made 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 6. The thickness of this raw material piece 16 is 1
9 is approximately three times the height of the wavy profile of the central longitudinal section of the insulating edge member. This piece of raw material 16 is cut with a contour cutter and separated longitudinally so that two identical insulating edge parts 20, 21 are obtained. Two identical insulation edges can be obtained with one cutting point 22.
The lower half of cut piece 16 is the insulating edge member shown in FIG. The upper half of the cut piece 16 has the same shape as the lower half. This is a cross-sectional view
You can see it better if you rotate it 180 degrees. Part piece 1 before cutting
It is not necessarily necessary that the thickness 19 of the insulation edge member 6 be twice the thickest thickness of the insulation edge member to be made, and the member piece 16 before cutting may have a wavy shape from twice the thickest thickness of the insulation edge member to be made. It is sufficient if the thickness is equal to the height of the outline. It is therefore only necessary that the thickness of the raw material piece before cutting be at least three times the thickness of the thin first longitudinal section 6 which is flat on both sides. In short, a flexible plastic material with a rectangular cross-section whose thickness 19 is about three times thicker than the height 15 of the contour 8 of the central longitudinal part 5 with the surface of the contour to be made is cut at the cutting point 22. cut horizontally to form a second flat-sided longitudinal section 7 having a thickness 11 no greater than the thickness 14 of the contoured central longitudinal section; A central longitudinal section with a longitudinal wavy profile is cut in a wave pattern, and finally a first longitudinal section 6 that is flat on both sides has a thickness 9 that is less than the thickness of the central longitudinal section. By cutting horizontally to form two identically shaped insulating edge members.

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 24 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 central longitudinal section 5 with a wavy contour and a thicker second longitudinal section 7 which are flat on both sides of the insulating edge member have a floating floor 17 and walls 18.
A first longitudinal section 4, which is arranged in the space between and is flat on both sides, is arranged below the thermal insulation layer 24. What is important is that the wavy contour 8 of the insulating edge extends horizontally and not vertically as in known insulating edges. The uppermost undulating profile and the flat second longitudinal section serve as a seal to prevent foreign objects from accidentally falling into the gaps between the troughs of the undulating profile. This purpose can be achieved even if the second longitudinal part 7, its free edge is slightly damaged during rough construction work, and even if a part of it is cut away, the floating floor 17 and the wall 18 The space can be sealed.

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 1 for the distance 10 between the trough of the wavy contour and the surface 1
5 is chosen 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, 200 mm,
The two flat longitudinal sections each have a width of 30 mm.
mm, the width of the central longitudinal part with a wavy contour is 140 mm. The thickness of the first longitudinal section, which is flat on both sides, is 4 mm. The height of the contour is 4 mm and the thickness of the central longitudinal section with the contour is 8 mm including the contour. The thickness of the thicker second longitudinal section, which has flat surfaces on both sides, is again 8 mm and thus corresponds to the total thickness of the central longitudinal section.
