Description

[Detailed description of the invention] insulation edge member The present invention provides an insulating edge for separating the edge and wall of a floating floor, especially for heated floors. Regarding parts.

For several years now, especially in new buildings, Caloheat has been carried out through conduits placed in the floor. It has become commonplace. This so-called f’Ju heating system is installed in the wall below the window. Special advantages compared to heating elements arranged in recesses, i.e. compared to homogeneous 7In thermal effects It also requires less heating energy than conventional heating methods.

Thermal expansion of a heated floating bed in a room with a so-called unheated method In order to do so, there must be space between the edge of the floor and the wall.

such floors touch or are firmly joined to the walls of the corresponding room Then, due to thermal expansion and contraction, the walls would be stressed and cracks would form.

Damage to the floor duct system may also occur.

However, open expansion joints generally cannot be used. This is because a space like this is uncontrollable or inadvertently occluded, ultimately resulting in unreliable Therefore, the connecting part cannot be omitted. Therefore, flexible structures, so-called insulating edges, Used in the space between the floor and wall.

The originally flat insulating edge member was bent into an L shape, and its vertical legs were heated to create a floating structure. between the floor and the wall, with the other short leg underneath the heated floating floor or above it at any time. between the underlying insulation layer and the upper side of the building's supporting floor. The edge member consists of a piece of impregnated or waxed corrugated cardboard fitted between the wall and the floor. The corrugated portion extends vertically along the wall. A piece of corrugated cardboard has its wavy surface A piece of corrugated cardboard with a perforated line extending perpendicular to it is folded to form the above L. You can create glyphs.

Boards with sealed laminate edges are also known. This is a layer of foamed plastic. It consists of a piece of corrugated cardboard. Insulated edges made of foamed plastic material imparts thermal and acoustic barrier properties. In particular, the transmission of impact sound from the sides is reduced. do.

A common drawback of both edge members is that the corrugated surface extends vertically along the wall. be. Foreign objects, e.g. small particulate building materials, can be found in open spaces extending perpendicular to the corrugated surface. It may fall and clog it. Such clogging may reduce the flexibility of the edge member. decreases. When the floating bed expands due to heating, the edge members are pushed together at this location. This creates a countervailing effect. Stresses between the wall and the floor or under the floor However, this must be avoided by edge members. Furthermore, the dust between the wavy surfaces From a hygiene standpoint, it's a good idea.

The cardboard used to make the twill parts of the Zara-Ko Corporation is in accordance with DIN standard 4102. It is identified as grade 83, that is, easily combustible. However, the 82nd grade, that is, the IF regular It is desirable that it be flammable or non-flammable. Finally laminated with cardboard The production of laminates consisting of a layer of plastinx material is quite expensive.

The object of the invention is to create a space between the wall and the floating floor without the drawbacks of known materials. fill in An object of the present invention is to provide a heat insulating member that can be manufactured at a lower cost than known members for the purpose.

This purpose consists of a flexible foamed plastic, which extends parallel to the longitudinal direction. a first longitudinal section (5); ) has a longitudinal corrugated profile, and its opposite surface (1) and the second longitudinal portion (4) has round surfaces (3) on both sides; The thickness 6) of the longitudinal part (4) is equal to the thickness 1 of the first longitudinal part (5) 9) One flat surface of the thinner, second longitudinal portion (4) Create a continuous surface (1) that is in the same plane as the flat surface (1) of the opposite part (5) To provide an insulating edge member having a contoured surface characterized by: This can be achieved by

Preferred embodiments of the invention are set forth in the claims.

The invention also includes a method of manufacturing the insulation member and its application to floating floors of buildings. Separation from the wall preferably includes the method of using it for the ground floor. In other words, the wall and the float The space between the floating floor is filled, the flat surface of the insulation member faces the floating floor, and the first The contoured surface of the longitudinal part of the wall should be on one wall, and the second side Place the flat longitudinal sections regularly on the supports.

In a preferred embodiment of the invention, one flat longitudinal thickness has individual undulations. between the lowest point of the surface and the opposite flat surface of the first longitudinal section with the corrugated surface; corresponds to the distance of

Preferably at the transition point between the first longitudinal section and the second longitudinal section. The corrugated surface t is notched on the side of the member, and the member extends in the longitudinal direction. It extends and makes it easy to concave the longitudinal part into an L-shape.

The wooden insulation edge is an integral element and is made of flexible plastic material. It is given from the fee. To obtain sufficient flexibility, foam plastic should be applied to the insulation edges. Styx materials are used, preferably closed foam. The foam contains various additives. Additives such as pigments, fillers, flame retardants can be included. include flame retardant is particularly suitable. This is because such heat insulating edge members meet DIN standards regarding flame retardancy. This is because good quality can be obtained using the 4102 method. The member is exposed to the heat of the floor. The fact is that the flexibility of the member should not reduce the mechanism that offsets the expansion. Therefore, the addition of flame retardants must be limited.

The plastics material is a closed cell polyethylene foam, such as expanded polyethylene foam. , foamed cross-linked polyethylene, or closed-cell polyvinylidene It is. However, materials other than foamable plastics and wax can also be used. be able to. Open-cell foams are also commonly used, but they provide thermal and acoustic insulation. Closed cell foam is preferred because of its good breakability. open cell plasticine The material is not suitable as it is because it is permeable to water. But open cell polyethylene In the case of foam, the flat surface of the edge member is covered with a foil or layer impermeable to liquids. Cover with Such coated side of the member is brought into contact with the floating bed. book to the member To prevent permeation, especially from newly poured concrete, edge members should be It may be useful to have a barrier layer on such sides that is impermeable to water.

The five-button foam edge member does not require such a barrier layer.

Confining edge members have sufficiently low compressive strength to avoid high stresses due to thermal expansion of the floor. However, this compressive strength is determined by the static load in the horizontal direction of the newly created floor. It has a value high enough to withstand heavy loads. Industry experts have selected foam materials Physical properties of materials, architectural requirements for specific jobs, and resulting U-engineering equipment With respect to .

Preferably the edge member is made of polyethylene foam meeting the standards of DXN 4102. able to make. Such foams are commercially available from several companies.

The uppermost corrugation of the edge member profile acts as a seal against the wall, so the gap is It is closed at the top and the debris falls into the contoured undulating gutter 3B between the edge member and the wall. There is no downside. Furthermore, these edge members can be manufactured very inexpensively using known equipment. can be done.

The edge member of the present invention can be manufactured by cutting a thick member in the longitudinal direction. Wear. However, the insulating edge members of the present invention can also be made by extrusion or heat processing. Ru.

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

FIG. 1 shows a sketch of a preferred embodiment of the insulating edge member of the present invention, and FIG. 2 shows the insulating edge member. Showing the raw materials of foamed plastic materials to show the manufacturing method of the materials, Figure 3 shows the edge of the room that accommodates the floating heat and edge members; Figures 4-8 2 shows a simplified section of another possible embodiment of an insulating edge member with different contours; FIG. .

FIG. 1 is a sketch of a preferred embodiment of the insulating edge member of the present invention. The first flat surface ( 1) is the underside of the edge member placed on the inside and thus in contact with the floor. the opposite of this edge The side surface has two different parts. The first longitudinal section (5) is corrugated (2), with the waves running in the longitudinal direction. First longitudinal section (5) A second longitudinal section (4) with a parallel surface (3) is inserted. first At the border between the longitudinal section (5) and the second longitudinal section (4) there is a longitudinal There is a notch between surfaces (2) and (3) in the direction, starting from the chain and ending at the edge. It extends to approximately half of the thickness 6) of the member. The cut C9) lengthens the member. It is bent toward the hand to form an L-shape, making it easy to install. Longitudinal direction with both sides flat (0 thickness is the trough-like part of the wave of the first longitudinal part (5) and the lower side of the member ( 1) is preferable. In the embodiment shown in Figure 1, , the height 10) of the wave (8) corresponds to the thickness (6) of the second flat-sided part (4) are doing. In other words, the distance (18) between the top of the wave (8) and the flat bottom (1) is It is twice the thickness 6) of the second flat longitudinal section (4).

The size of the insulating edge member shown in Figure 1 allows the member to be easily attached using conventional equipment. The material is selected in consideration of the mechanical strength and flexibility of the member.

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

- Butestinx, which exists in a long shape with foam at the crotch #The door has a contoured cut. Plastics material cut horizontally with a cutting machine and having a specific contour of at least -. It is known that pieces of material can be made.

In order to make the heat insulating edge member of the present invention, it is necessary to have a rectangular cross section as shown in FIG. Use the member piece (11). This raw material piece (11) is cut into a contour cutting machine. When supplied, you will get 2 bonds of material (13, 14). length with second flat surface To form the hand section (4), both edges of the two pieces of material (13° and 14) Cut out a number of corrugations (15) or (16) at the desired width and make both sides flat. A straight longitudinal section must be created. The cutting line is the number (20, 21). Comparing Figures 1 and 2, we can see that the lower cut of piece (11) is The section is the same as the side piece in Figure 1, and the upper part is again attached to the lower part of the Figure 1 piece. Although it is attached, it can be seen that it has been rotated 180'. Raw material pieces (11) The thickness of the raw material piece (18) does not need to be twice the maximum thickness of the piece made. It is important that 11) can have a thickness reduced by the wave height 1o). Ru. Therefore, this thickness only needs to be three times that of the portion (5) in the direction of the yam, where both sides are flat.

This allows considerable savings in raw material costs.

If open-pore foam is used, ÷ should be laminated with a water-impermeable film after manufacture. Changed. When making the shoulder piece by extrusion, use the simultaneous extrusion method to make the transparent layer 7. We can create it together. Closed-cell foams are also commonly fitted with barrier layers. I can do it.

Figure 3 shows how the heat insulating edge member is installed between the wall and the floor. Figure 3 shows the bildy The supporting floor (22) of the building and the associated wall (18) of the building are shown.

Also shown is the insulation layer (23) and the heated floating bed above it. This insulation method The equation is typical for bed heating. The floating bed (17) is for heating the bed. Contains a conduit (25). The insulation edge member of the present invention is connected to the wall (18) and the wall (17). The part (5) of the edge member with a contour is installed in the space between the floating floor (17) and g ( There is a pickpocket in the space between the insulation layer (23) and the flat piece (4) on both sides. Make it come down. What is important is that the corrugations (8) of the heat insulating edge members extend horizontally. It does not extend vertically like the insulating edge members. The top waveform is the waveform It acts as a sealing material to prevent foreign objects from accidentally falling into the gap in the gutter. present invention The edge members do not promote thermal expansion of the floating bed and also prevent the ingress of unsanitary substances.

The contour of the insulating edge shown in FIGS. 1 to 3 consists essentially of a sine wave.

However, various shapes are possible, some of the profiles of which are shown in Figures 4-6.
