Description

The invention relates to an installation board, comprising an insulation board which has at least one flat area and at least one channel-shaped recess on its upper side, and a heat-conducting sheet with a flat flat area and at least one trough-shaped recess for receiving a fluid-carrying pipe, the flat area of the heat-conducting sheet being the flat area Covered area on the upper side of the insulation board and the channel-shaped recess accommodates the channel-shaped depression, as well as surface heating or cooling comprising at least two installation panels, as well as a method for manufacturing an installation panel.

One application of these installation panels can be the installation of surface heating or cooling. It is also conceivable to arrange the installation plates on the wall or on the ceiling to accommodate heating pipes and / or cooling pipes.

Underfloor heating in particular has become more and more popular in recent years. An important reason for this is the comfort of being able to go barefoot in the house even in winter. Another advantage is that conventional radiators can be dispensed with, which saves space in the respective rooms. There is also no need to clean these conventional radiators, which is often time-consuming and laborious. In addition, the even surface heat from the underfloor heating ensures that undesirable organisms such as house dust mites or mold cannot multiply as much.

The pipes for the surface heating are laid either with the help of the wet system, i.e. in the screed, or the dry system, i.e. outside the screed. In the last variant, prefabricated installation panels, which usually include an insulation panel and a heat-conducting layer, play an important role. Channel-shaped recesses can be milled into these insulation panels beforehand. The heat-conducting layer, usually in the form of a heat-conducting sheet, can be reshaped so that a channel-shaped depression for receiving a fluid-carrying pipe, usually a composite pipe for carrying heating water, is formed. In the composite of the insulation board and the heat conducting sheet, several installation plates can be laid in whole or in part in a room. The fluid-carrying pipes can then be introduced into the channel-shaped depressions. Laying panels of this type make laying underfloor heating much easier and is therefore designed to be feasible even for the hobbyist. These installation panels are mainly used in the renovation of an old building or surface heating in solid wood construction in order to retrofit these, whereby the installation panels are placed on the existing floor. After the pipes have been introduced, the new flooring, dry screed or wet screed can then be laid directly on the installation plate. However, it is also conceivable that this system will be used in new buildings. The advantage arises from this that the underfloor heating can be implemented in dry construction.

Laying plates of the generic type for receiving heating pipes for underfloor heating are well known from the prior art. The insulation boards in the prior art usually consist of a base material such as styrofoam, dry screed or soft wood fiber, in which the planned shape for the heating pipes can be milled. For better heat distribution, a heat-conducting layer in the form of a heat-conducting sheet is usually applied to the insulation board.

Disadvantages of these known systems, however, are that Styrofoam has a very low compressive strength and can therefore be damaged very easily during storage or laying of the prefabricated panels. Even after installation, there is a risk that the styrofoam will be damaged if the plate is improperly loaded. Dry screed has the disadvantage that, firstly, it is more expensive than standard screed, also because the design with dry screed requires more precise planning, and secondly, with underfloor heating, the permissible upper temperature limit may not correspond to the desired value, as the properties of the material used are taken into account got to. Soft wood fibers as the base material for the insulation board are most common in the prior art. However, the structure is so tight and hard that the heat conducting plates have to be glued or screwed onto the insulation panels. The disadvantage of the adhesive connections is that they wear off over time, so that the heat conducting sheet can detach from the insulation board. A screw connection has the disadvantage that screws have to be introduced into the installation plate as a further component. This is costly and complex to manufacture. In the development of the installation panels, there are already initial attempts to create a cost-effective, mechanical connection between the insulation panel and the heat-conducting sheet. A kind of tongue is cut into the heat baffle, which protrudes into the softwood fiber board at an acute or right angle. However, these connecting elements do not achieve the necessary strength. Soft wood fiber boards can only enter into a firm connection with inexpensive connecting elements to a limited extent, as these are difficult to form on the surface. Second, it can be seen that fasteners that are only under one at an acute or right angle in the soft fiber board, which can be easily loosened towards the top.

It is therefore the object of the present invention to develop an installation plate, preferably a surface heating system for receiving heating and / or cooling pipes, the insulating plate of which has a suitable structure to establish a simple and inexpensive mechanical connection with the heat conducting plate, and additionally a has high compressive strength, and to provide an inexpensive and easy-to-manufacture fastening device that connects the insulation board and the heat-conducting sheet firmly and permanently to one another.

The object of the invention is achieved by an installation board, comprising an insulation board, which has at least one flat area and at least one channel-shaped recess on its upper side, and a heat-conducting sheet with a flat flat area and at least one channel-shaped recess for receiving a fluid-carrying pipe, the flat area of the heat conducting sheet covers the flat area on the top of the insulation board and the channel-shaped recess receives the channel-shaped depression, with at least one fastening device torn like a hole in the flat area and in the flat area forming at least one fastening element which protrudes at least partially from the flat area at an obtuse angle and protrudes into a corrugated cardboard structure of the insulation board.

The material selected for the insulation board with a corrugated cardboard structure can advantageously be used to achieve an installation board which, on the one hand, has an extremely high compressive strength and, at the same time, can be manufactured cost-effectively. On the other hand, the selected insulation board is advantageously suitable for being torn like a hole on the cellulose top. As a result, the top and the corrugated cardboard structure underneath are only deformed or destroyed at certain points, but the overall strength, and above all the high compressive strength of the material, does not suffer.

The fastening device is created in that the flat area of the heat conducting plate and the flat area of the insulation board, the flat area covering the flat area flush and in a flat contact, are jointly torn at least at one point like a hole. The joint deformation of the flat area, the flat area and the corrugated cardboard structure creates a form-fitting, mechanical connection. The fastening device advantageously forms a fastening element.

The fastening element protrudes from the flat area at least partially at an obtuse angle. In the prior art, fastening elements are known which are at a flat angle or at a right angle from the flat area. In the prior art, the fastening element is flat to vertical. The obtuse angle of the present invention extends beyond 90 degrees, that is, it is greater than 90 degrees and less than 180 degrees.

The fastening element protrudes into the corrugated cardboard structure of the insulation board at the obtuse angle. The obtuse angle has the advantage that the heat-conducting plate is fixed to the heat-conducting plate in the horizontal and vertical direction due to the both horizontal and vertical components of the obtuse angle. Furthermore, due to the obtuse angle that is formed, there is advantageously deformed material of the insulation board, i.e. top and corrugated cardboard structure material, between the fastening element and the flat flat area of the heat conducting sheet, so that a form-fitting connection is created.

"Cracked like a hole" in this context means that in the manufacturing process, preferably through an at least partially blunt object, a vertical force was applied to the flat area of the heat conducting sheet, to the flat area underneath and to the corrugated cardboard structure until the material yielded to the force and thus at least partially tear like a hole. In contrast to cutting or punching, irregular but desired structures are created here. The material of the heat conducting sheet, the surface and the corrugated cardboard structure is bent or pressed together at the edge of the hole-like crack downwards and preferably to an at least partially obtuse angle by penetration of the blunt object beyond a perpendicular angle to the flat area. The joint deformation of the flat area of the heat conducting sheet and the surface and corrugated cardboard structure of the insulation board advantageously creates a firm, mechanical connection, with the material wedged into one another around the hole-like crack. The installation plate can thus advantageously be installed as a component in a room.

The heat conducting sheet consists in particular of aluminum. However, other metals or materials, such as copper or graphite, or particularly conductive plastics can also be used.

According to a preferred embodiment, the at least one fastening element is formed in one piece with the heat conducting plate. This has the advantage that in addition to the heat conducting plate and the insulation board, no additional materials have to be introduced for fastening. That Fastening element is created by the hole-like tearing of the heat conducting sheet at the edge of the hole, the fastening element being formed from the material of the flat area. The fastening element is preferably tooth-like and sharp-edged, so that it is advantageously connected to the corrugated cardboard structure. One-piece accordingly means that the heat conducting plate and the fastening element are made from one part and are connected at the molecular level.

According to a further, preferred embodiment, the at least one fastening device firmly connects the heat-conducting sheet to the insulating plate, the at least one fastening element and the corrugated cardboard structure being positively connected. The fastening element and the corrugated cardboard structure can preferably also be positively connected. Furthermore, it is conceivable that whatever heat-conducting sheet is additionally glued to the surface of the insulation board or that further fastening devices, which are known in the prior art, are used to connect the boards.

According to a further, preferred embodiment, the at least one fastening device forms a hole in the flat area of the heat conducting sheet and in the surface of the insulation board. Since the hole of the flat area and the surface are formed jointly and thus lie one above the other, this hole can be regarded as a joint hole. When viewed from above, the structure of the corrugated cardboard can be seen at least in part. Furthermore, viewed from above, the hole can assume any shape and size that is considered expedient for a fastening device. This can be, for example, and at least approximately round or polygonal. The cross-sectional area of the hole preferably corresponds to 10 mm ² to 50 mm ² , preferably about 25 mm ² . The hole is preferably slot-shaped with a length of 10 mm and a width of 2-3 mm. More preferably, the slot is at least approximately T-shaped and forms several connecting elements on the wall side. Because the hole is created by tearing it open, the hole is at least partially irregular, but a fundamentally identical design of the hole can be seen.

The at least one fastening element is preferably formed from the heat conducting sheet and protrudes at least partially in a height direction downward on the wall around the hole in the corrugated cardboard structure. The hole thus has a certain depth in the vertical direction. Downward on the wall side is not to be equated with vertical, it being possible for vertical components of the at least one fastening element to be present. However, the fastening element also has at least components that protrude from the flat area at an obtuse angle. The fastening element is preferably bent so that the wall of the hole widens in a cone-like manner in the downward vertical direction. Furthermore, the process of tearing open results in the wall of the hole not being completely closed, with individual wall elements of the hole forming the at least one fastening element of the fastening device.

According to a further, preferred embodiment, at least two first fastening elements of a fastening device are bent opposite one another in the longitudinal direction. Alternatively, the two fastening elements can be bent opposite one another in the width direction.

This has the advantage that the first fastening elements are firmly anchored and clamped in the corrugated cardboard structure in the opposite direction. A vertical or horizontal detachment of the heat conducting sheet from the insulation board is thus prevented.

According to an alternative or cumulative, preferred embodiment, at least two fastening devices that are adjacent in a width direction each form at least one second fastening element, the at least two second fastening elements being bent opposite one another in the width direction. Alternatively or cumulatively, the fastening elements can be adjacent in the longitudinal direction.

This also has the advantage that the second fastening elements are firmly anchored and clamped in the corrugated cardboard structure in the opposite direction. A vertical or horizontal detachment of the heat conducting sheet from the insulation board is further advantageously prevented with a combination of the first and second fastening elements.

According to a further preferred embodiment, the corrugated cardboard structure has corrugated cardboard elements that extend in a longitudinal direction and run next to one another in a width direction and have a horizontal oscillation plane spanned by the longitudinal direction and width direction.

More preferably, the corrugated cardboard structure has straight cardboard elements running in the longitudinal direction in contact between the corrugated cardboard elements. The orientation of the wave-shaped and straight cardboard elements with a stiffening force acting in the vertical direction ensures a high overall strength of the installation board. It is advantageous if the cardboard elements are sheet-like, that is, have a thickness that is in the It is small compared to its length and width, as this saves material and, at the same time, the orientation of the cardboard elements ensures high strength.

In this context, contacting means that the corrugated cardboard elements are connected to one another at least in places with the straight cardboard elements. The wave peaks and the wave troughs of the wave-shaped cardboard elements preferably contact the straight cardboard elements. This makes it easier to cut out the channel-shaped recesses, since the insulation board as a whole, for example in the form of a board 1 m long and 0.5 m wide, can be stretched for the milling process. After the groove-shaped recesses have been milled and connected to the heat-conducting sheet, the installation plate is also easy to transport, store and lay, since all cardboard elements are connected to one another.

In order to ensure the most permanent contact possible, which promotes the strength of the cardboard elements, it is advantageous if the cardboard elements are glued to one another. In particular, it is advantageous if these are glued to one another in a wet-strength manner. It is also advantageous if these are glued to one another in their contact area.

Another advantage of this structure is that the space between the cardboard elements is filled with air. This makes the insulation board particularly light. Air is also a good heat insulator, so that a good insulating effect can be achieved.

More preferably, the cardboard elements extend in a height direction so that the insulation board has a height of preferably 20 mm to 25 mm, particularly preferably 20 mm. At the channel-shaped recesses, the height is correspondingly lower by the depth of the recess.

More preferably, the top and a bottom of the insulation board are made of solid cardboard, paper or kraft liner and are connected to the corrugated cardboard structure, preferably glued, more preferably glued to one another in a wet-tight manner. The installation panels are laid on the floor with the underside downwards.

It can further be provided that a parallel separating layer is present in the corrugated cardboard structure between the upper side and the lower side.

In addition, the upper side, the lower side or the separating layer can be equipped with a moisture-resistant, but vapor-permeable protective layer.

According to a further, preferred embodiment, the insulation board has at least one channel-shaped recess with a rectangular cross section.

According to a further, preferred embodiment, the at least one channel-shaped depression has an omega cross section, the tube being able to be introduced into the heat conducting plate by a reversibly expandable tapering of the omega cross section. The omega cross-section is shown in the description of the figures and in the 5 described in more detail.

The tapering advantageously has a smaller opening width than the tube, so that an inserted tube cannot unintentionally lift out again into the channel-shaped depression. This could be the case, for example, if the tube expands in length due to a heated fluid that is guided in the tube.

Accordingly, when the tube is introduced into the recess, a force must be applied against a resistance of the taper, the taper being able to be widened by the action of the force. The reversible widening has the advantage that the taper can be narrowed again automatically after the pipe has been introduced.

According to a further, preferred embodiment, the at least one channel-shaped recess and the at least one channel-shaped depression run in a straight line and / or curved in a horizontal plane.

The bending angle is preferably 90 degrees or 180 degrees, but other bending angles are also conceivable.

A combination of different shapes is also conceivable, so that a straight section of the depressions is followed, for example, by an arcuate section and this is followed by a straight section. The course of the depressions ideally takes into account both geometric specifications such as the size of the installation plate or the minimum bending radius of the pipes as well as functional specifications, i.e. in particular the achievement of a uniform pipe distribution in the room.

It is also conceivable that both heating and cooling pipes are arranged. This can be advantageous if two adjacent sections of a room are to be heatable on the one hand, but also to be able to be cooled. It is also conceivable that one and the same section of a pipe is used both as a heating and as a cooling pipe, in that the temperature of the fluid that flows through the pipe can be changed and thus on the one hand high and on the other hand low. This can be advantageous for a room provided with installation panels according to the invention, which in this way can be heated in winter and cooled in summer.

In particular, the underlying object is achieved by surface heating or cooling, comprising at least two installation plates in a preferred embodiment according to the invention, whereby by placing the at least two installation plates next to each other, the at least one channel-shaped depression is flush with the other channel-shaped depression.

Correspondingly, the channel-shaped recesses also connect flush with one another, as do the side surfaces of the installation panels.

The installation plates are preferably standardized, for example by the dimensions of the installation plates in height, length and width, and / or by the spacing of the recesses in a installation plate. As a result, any number of installation plates can advantageously be combined with one another. The base areas of the installation plate are preferably rectangular.

Laying panels can also be advantageously combined with curved or straight laying panels so that rooms and even entire floors can be covered with laying panels in a meaningful way. The installation panels can preferably be cut to size according to the size of the room.

In particular, the underlying object is also achieved by a method for manufacturing an inventive or preferred installation panel, comprising the following method steps:

1. a. Placing the insulation board on a workbench of a manufacturing facility, with the top face with the groove-shaped recess facing upwards,
2. b. Placing the heat conducting sheet on the top of the insulation board, with the channel-shaped recess receiving the channel-shaped depression,
3. c. Applying a force perpendicular to the heat conducting plate to the flat area by means of an at least partially blunt tool,
4. d. Hole-like tearing of the flat area and the surface with at least partial penetration of the tool into the corrugated cardboard structure through the flat area and through the surface, wherein at least one fastening device is formed with at least one fastening element that protrudes at least partially at an obtuse angle from the flat area and into the corrugated cardboard structure of the Insulation board protrudes.

Preferably, between process steps b. and c. a perforated plate placed on top of the heat conducting sheet, the perforated plate having several recesses at those points in the longitudinal and width directions at which a fastening device is to be formed in the installation plate.

Preferably, the insulation board, the heat conducting plate and the perforated plate are prior to process step c. tense. Thus, the layers can advantageously no longer slip.

The perforated plate also offers the advantage that when a force is applied perpendicular to the heat conducting plate, the flat area and the insulating plate located below it are only deformed at certain points.

The blunt tool is preferably clamped in a machine which executes a firmly defined movement perpendicular to the heat conducting plate from top to bottom.

The machine preferably comprises a multiplicity of identical, blunt tools, preferably in the number of desired fastening devices per installation plate. As a result, all of the fastening devices per installation plate can advantageously be formed in one work step.

"Hole-like tearing" in this context means that, preferably through the at least partially blunt object, a vertical force is applied to the flat area of the heat conducting sheet and to the underlying surface and corrugated cardboard structure until the material yields to the force and thus at least partially tears like a hole. The material of the heat conducting sheet, the surface and the corrugated cardboard structure is bent or pressed downwards together at the edge of the hole-like crack and preferably by penetration of the blunt object beyond a perpendicular angle to the flat area. By jointly deforming the flat area of the heat conducting sheet and the surface and corrugated cardboard structure of the insulation board, a firm, mechanical connection is advantageously created, with the material wedged into one another around the hole-like crack.

The at least partially obtuse angle results from the fact that the connecting element is bent downwards, beginning at its tip, up to the edge of the hole. As a result, the connecting element takes on a circular arc-shaped bend, preferably at an arc angle of 45 degrees to 90 degrees. According to the invention, the fastening element projects, preferably in the region of its tip, at an obtuse angle from the flat region.

the 1 shows a section of an installation plate 1 in a preferred embodiment, comprising an insulation board 2 and a heat baffle 3 , which in a height direction H on top of the insulation board 2 rests. A flat area 2c on a surface 2a the insulation board 2 makes contact with a flat area 3a of the heat conducting sheet 3 .

The insulation board 2 has a groove-shaped recess in this section shown 4th on the in the direction of height H and straight in a longitudinal direction L. along the top 2a the insulation board extends. The groove-shaped recess 4th is just big enough that it has a groove-shaped recess inside 5 of the heat conducting sheet 3 in height direction H and length direction L. can accommodate. The groove-shaped depression 5 is made in one piece from the heat conducting sheet 3 formed, for example by reshaping the sheet. Inside the channel-shaped recess 5 extends essentially along the longitudinal direction L. a pipe 6th that in height direction H and lengthways L. completely in the groove-shaped recess 5 is recorded.

In the excerpt shown there is a bit of a corrugated cardboard structure 20th in an interior of the insulation board 2 recognizable, which is essentially in the longitudinal direction L. and width direction B. extends. In height direction H becomes the corrugated cardboard structure 20th through the top 2a and a bottom 2 B the insulation board 2 limited.

The installation board 1 further comprises several fastening devices 10 , 10a , 10b on that extends over the flat area 3a in width direction B. and longitudinal direction L. extend evenly distributed. In height direction H extends the fastening device 10 , 10a , 10b down through the top 2a into the corrugated cardboard structure 20th , the fastening device 10 , 10a , 10b a hole 12th in the flat area 3a and in the flat area 2c has so that at least partially through the hole 12th the corrugated cardboard structure 20th is disclosed.

the 2a shows a top view of one of the insulation board 2 insulated heat conducting sheet 3 according to a preferred embodiment. The hole 12th that by the fastening device 10 , 10a , 10b is formed, corresponds essentially to the shape of the letter T, with the proportions of the hole 12th are distributed differently compared to the letter T. Longitudinal L. the hole is about 10 mm long and in the width direction B. about 2 mm wide at the narrow point, and 3 mm wide at the broad point. Longitudinal L. are two adjacent holes 6th about 65 mm away, in the width direction B. spaced about 25 cm. The specified dimensions are only exemplary values. In addition, the shape and size of the hole 12th , as well as the distances to each other can also be chosen differently.

the 2 B shows a bottom view of one of the insulation board 2 insulated heat conducting sheet 3 according to a preferred embodiment. The fastening devices 10 , 10a , 10b form one piece with the heat conducting plate 3 the fasteners 11 , 11a , 11b the end. In the embodiment shown, the fastening devices 10 , 10a , 10b two first fastening elements each 11a on that in the longitudinal direction L. opposite to each other and in the vertical direction H are bent downwards. The first two fasteners 11a are accordingly opposite at the hole 12th the fastening device 10 , 10a , 10b arranged and stand around the vertical axis H rotated at an angle of 180 degrees to each other.

The fastening devices 10 , 10a , 10b each have a second fastening element 11b on which in the width direction B. and in height direction H is bent downwards. Corresponding stands around the vertical axis H rotated the second fastener 11b essentially each at an angle of 90 degrees to the first fastening elements 11a .

One lengthways L. adjacent fastening device 10 , 10a , 10b is designed essentially identically, which differ slightly from one another due to the manufacturing process step of the hole-like tearing open. However, all fasteners achieve this 10 , 10a , 10b the same technical effect.

One to a fastener 10a in width direction B. adjacent fastening device 10b is designed essentially identically, but around the vertical axis H turned 180 degrees. Consequently, the respective second fastening elements 11b in the width direction B. curved downwards in opposite directions.

The flat area 3a of the heat conducting sheet 3 lies flush and contacting on the flat area 2c the top 2a the insulation board 2 on. The hole-like in the flat area 3a and in the flat area 2c torn fastening devices 10 each have two first fastening elements 11a and a second fastener 11b on. In this sectional view it can be seen that the fastening elements 11a at least partially at an obtuse angle α from the flat area 3a stick out and into the corrugated cardboard structure 20th protrude into the insulation board. On the fastening devices 10 is the corrugated cardboard structure 20th deformed by the hole-like tearing. The corrugated cardboard structure nestles advantageously 20th around the fasteners 11 , 11a , 11b so that the fasteners 11 , 11a , 11b by joint deformation firmly with the corrugated cardboard structure 20th are connected. A detachment of the heat conducting sheet 3 from the insulation board 2 is not possible under normal force, because the fastening elements 11 , 11a , 11b in all directions in the corrugated cardboard structure 20th are wedged.

The fastening elements advantageously have 11 , 11a , 11b as on the fasteners 11a can be seen in the figure, a substantially circular arc-shaped bend. The fasteners 11 , 11a , 11b make at least partially the wall of the hole 12th so that the hole 12th is advantageously widened cone-like downwards and the detachment or displacement of the heat conducting sheet is further prevented.

In relation to the height of the insulation board 2 has the fastening device 10 , 10a , 10b only a small depth, for example 3 mm of the fastening device 10 , 10a , 10b compared to 20 mm of the insulation board 2 . Below the fastening devices 10 , 10a , 10b the corrugated cardboard structure remains 20th largely preserved and guarantees a high level of strength of the insulation board 2 . Away from the fastening devices 10 , 10a , 10b the corrugated cardboard structure remains 20th anyway untouched and stable.

the 3b shows a sectional view of a laying plate 1 along the width direction B. according to a preferred embodiment, wherein the bend of the second fastening element 11b in width direction B. can be seen downwards. The second fasteners 11b two adjacent fastening devices 10a , 10b are bent in opposite directions from one another and thus advantageously synergistically prevents the detachment or displacement of the heat conducting sheet 3 from the insulation board 2 .

Here you can see that the corrugated cardboard elements 21 with one through the longitudinal direction L. and width direction B. spanned horizontal plane of vibration E2 and the straight cardboard elements 22nd the corrugated cardboard structure 20th essentially in the longitudinal direction L. spread out, alternating a wave-shaped cardboard element 21 and a straight cardboard element 22nd are arranged adjacent to one another in the width direction. The straight cardboard elements 22nd run in the longitudinal direction L. parallel, the phases of the corrugated cardboard elements 21 are slightly offset lengthways.

Between the cardboard elements 21 , 22nd cavities are formed, which are preferably filled with air. This results in a particularly light, but nevertheless extremely robust structure.

The cardboard elements 21 , 22nd are with each other along lines of contact of wave crests 21a and wave troughs 21b each glued. In particular, this is a corrugated cardboard structure 20th with the top 2a and the bottom 2 B glued to the insulation board.

the 5 shows an omega cross-section 5a the channel-shaped depression 5 according to a preferred embodiment. The cross section of the channel-shaped depression essentially has 5 the shape of the Greek capital letter omega (Ω). Inside the insulation board 2 is the omega cross-section 5a essentially round, making a tube 6th can be positively stored in the channel-shaped recess. To the top, i.e. to the top 2a the insulation board 2 down, is the channel-shaped depression 5 opened, this opening having a taper 5b represents, according to which the width of the taper is narrower than the diameter of the pipe 6th .
