Description

The invention relates to a Velcro fiber board.

For heating and cooling rooms, it is known to lay pipe systems in floors, walls or ceilings. The corresponding pipe systems are traversed by water or steam and thus heat or cool a surrounding space. Before suitable pipelines are poured with a layer of screed into floors, walls or ceilings, the pipes are mounted on supports by means of suitable rails or holders. These beams or semi-finished elements are partially finished and must be delivered to the site and assembled on site.

A more flexible system is possible with on-site attachable rails and support systems that are used on appropriately pre-perforated supports by an installer. In this way, the pipe systems and supports can be adapted to the given room situation. Although these systems are more flexible and cheaper than (semi) finished elements, nevertheless, several steps are still necessary and a subsequent change in the publishers of the pipe system is possible only by additional steps. In most cases it is also necessary to provide special tools for the installation.

There is therefore a need to provide a device for laying heating and cooling systems, in particular floor heating systems, which are both less expensive and more flexible in use.

The object is solved by the subject matter of the independent claim. Further advantageous embodiments are the subject of dependent claims.

In one embodiment, the hook and loop fiberboard comprises a fabric reinforced film or other adhesive material adapted to releasably secure a flexible pipe, in particular a plastic pipe, composite pipe or metal pipe, by means of a hook and loop device. The Velcro device has for this purpose a first and a second element. The film is provided flat with a first element. In this case, the first element preferably comprises the entire surface of the film. The flexible tube has a second element and is at least partially encased by this. The Velcro fibreboard further comprises a dimensionally stable planar support, on one side of which the film is attached.

The film is attached, for example, on the dimensionally stable sheet-like support by means of an adhesive or in some other way preferably insoluble. The carrier with the film is first introduced into the room in which, for example, a floor heating system is to be installed. For this purpose, the dimensionally stable planar support can be tailored accordingly and thus complete the entire room. Preferably, the carrier itself is placed or fastened on a further layer, which may for example have different insulating materials. Once the planar carrier has been applied together with the foil, an installer can flexibly and releasably apply the flexible tube, in particular the plastic tube, to the flat carrier. For this purpose, the first and second elements engage each other so that a detachable connection is formed. It is not specified by using the Velcro fiber board how the pipe should be laid. Rather, it is the installer by means of the Velcro device or the planar application of the first element in a very flexible way possible to move the tube as desired and also to solve again, if a different course of the tube is desired or a correction is necessary. At the same time the Velcro device causes the tube remains on the film and does not float when, for example, a screed or other building material is placed on the carrier.

The Velcro fiber board is a quick and flexible system for easy installation of a heating or cooling system, preferably a floor heating, presented without other special tools. Advantageously, it is possible to carry out the entire installation by a single person. Also, a subsequent position correction of the laid pipes is easily possible. The Velcro fiber board thus enables a flexible pipe installation, which can be adapted to different room geometries. By means of the Velcro corresponding many possible adhesion points for laying the flexible tube are realized. This is of particular advantage because it makes it possible to lay the tube without specification by separate components or fasteners almost anywhere along the film. In this way, a particularly simple and flexible installation is given, which allows not only to make corrections, but also to enclose almost any spatial geometries easily. Furthermore, the tubes lie in one plane without significant height deviations. Another advantage is that an insulating layer for the heating can be made separately from the Velcro fiber board and laid. This significantly reduces the cost of laying the floor heating.

In order to reduce structural requirements, for example with regard to impact strength and insulating behavior on the dimensionally stable, flat support, the film is made of fabric reinforced. Through this reinforcement, the film itself is more stable and thus takes over as stabilizing tasks. Of It is also possible through the fabric reinforcement that when laying the flexible tube slight bumps can be compensated by the tube is pressed into the film. Due to the flexibility of the film and a slight indentation, the connection between the first and second element is improved and the tube adheres better to the foil.

In the text which follows, a fabric-reinforced film is a film which, due to its material properties, is elastic and gives way under the action of a pressure.

According to a further embodiment, the hook and loop device comprises hooks or fibers which can detachably engage in a velor fabric.

With the help of hooks or fibers of the Velcro device, a detachable connection between the film and the flexible tube is made possible together with the velor fabric. In this case, the Velcro device interlocks by means of hooks or fibers in the film on the dimensionally stable planar support and thus fixes the tubes. The Velcro device and the film are preferably optimally matched to each other for maximum holding forces. This is ensured inter alia by a high number of support points, which extend to some extent along the entire tube or the film.

According to a further embodiment, the first element comprises a Velcro material and the second element the velor fabric.

According to a further, alternative embodiment, the first element comprises the velor fabric and the second element Velcro material.

In a further embodiment, the film is provided in such a flat manner with the first element that the flexible tube can be detachably connected to the film at any desired locations.

The flat hook-and-loop device designed in this way allows pipe laying over the entire surface of the film. In this way, a special flexibility is realized, which also offers an advantageous stability of the laid pipes. The flexible tube will, so to speak, find suitable adhesive points along the entire surface of the film which can releasably bond it to the film. These detachable connections in turn make it possible to lay the tube in almost any geometry, without a pipe run would have to be defined in advance in a further step by means of suitable separate components or fasteners. Also, it is possible in a particularly simple manner to correct the pipe run by the connection is released.

According to a further embodiment of the dimensionally stable planar support is designed so that it is designed to be stable according to the laying of the pipe, in particular as part of a floor heating. In this case, this carrier can be constructed of different materials. Alternatively, these materials may comprise wood fibers, plastics such as polymer based, polystyrene or suitable blending materials such as composites or biofibers. Also metallic materials, such as a suitable corrugated metal sheet, are possible.

One possible criterion in the selection of the material is, for example, its tread resistance. This allows on the one hand a safe installation of the pipe by a specialist, but in the long term also contributes to the longevity of the laid heating or cooling system. Criteria for building protection and building regulations can also be incorporated into the choice of materials. In particular, the material should be suitable to carry a screed.

According to a further embodiment, the dimensionally stable, flat carrier is provided on its other side with a covering film, in particular a plastic covering film.

According to a further embodiment, the cover foil is made water-repellent.

With the help of the cover an effective water protection is possible, for example, prevents moisture or from the heating system leaking water can penetrate into the room floor or the insulating material.

In a further embodiment, the cover is after the Standard DIN 18560 T2 executed.

According to a further embodiment, an elastic coating is arranged between the dimensionally stable planar carrier and the Velcro film.

The elastic coating allows a certain yielding in the attachment of the flexible tube and thus additionally serves the improved pipe fixation. Even minor bumps in the ground can be compensated.

In a further embodiment, the elastic coating has a thickness between 2 and 3 mm.

According to a further embodiment, the dimensionally stable planar carrier has holes.

With the help of the holes in the dimensionally stable support, this can be used, for example, with structures in the room in which the underfloor heating system is laid should fix, or even below adjacent carriers.

According to a further embodiment, the holes in the dimensionally stable planar support are adapted to fix the carrier.

According to a further embodiment, the dimensionally stable flat carrier for fastening the Velcro fiber board is carried out with at least one further Velcro fiber board by means of fasteners for fastening.

With the help of the fasteners Velcro fiber boards can be interconnected. Preferably, the edges are designed so that they engage in such a way that a firm attachment of the plates is made possible with each other. For example, the connecting elements can be designed as a meandering shape.

According to a further embodiment, the dimensionally stable flat carrier has a thickness of between 2.0 and 5 mm, but may also comprise other thicknesses due to material or production.

According to a further embodiment, the flexible tube is set up for a heating system or a cooling system. Preferably, the heating system or the cooling system are introduced into a floor.

According to a further embodiment, the film or the dimensionally stable planar support also performs the function of impact sound insulation and / or thermal insulation.

The invention will be explained in more detail below with reference to several exemplary embodiments with reference to FIGS. As far as parts or components correspond in their function, their description is not repeated in each of the following figures.

Show it:

1 an exemplary embodiment of a Velcro fibreboard according to the proposed principle,

2 a further exemplary embodiment of a Velcro fibreboard according to the proposed principle, and

3 a plan view of a Velcro fiber board according to the proposed principle.

1 shows a Velcro fibreboard according to the proposed principle, which is designed to install a heating or cooling system, for example, for a floor can. In this case, the Velcro fiber board comprises several components that can be configured differently and supplemented by other components.

For the design of the heating or cooling system finds a flexible tube 2 Use. This is in particular made of a plastic, wherein preferably crosslinked polymers are used. This allows the flexible tube 2 be adapted to the respective field of application. For example, the flexible tube 2 have a higher temperature or pressure resistance. A particularly suitable material is polyethylene (PE). Furthermore, the choice of material is also based on construction standards and the relevant industry standards. To DIN 4726 can the flexible pipe 2 also be made particularly oxygen-tight. Length of the flexible tube 2 and its pipe diameter depend on the specific application and can vary.

The flexible pipe 2 has a velor or adhesive material at the factory 22 on. This preferably surrounds the flexible tube in a spiral shape 2 , It is alternatively possible, the flexible tube 2 with the velor or adhesive material 22 to coat.

A fabric-reinforced film 1 has a hook and loop device, which is a Velcro material 21 and a velor fabric 22 includes. The Velcro device is, also factory-prepared and firmly connected, on a dimensionally stable planar support 3 or the flexible tube 2 , The Velcro material 21 It has small hooks, fibers or loops, which are in a suitable material, such as a velor or adhesive material 22 can intervene. Characteristic is that a connection between the Velcro material 21 and the velor or adhesive material 22 Although it has a certain strength, but basically can be solved by a single person. The desired connection strength depends on how velor or adhesive material 22 and the velcro material 21 mesh. Preference is given to a micro-toothing, which is particularly stable and has many microns large teeth.

The foil 1 is flat with the Velcro material 21 provided, wherein preferably the entire surface of the film 1 is covered. The foil 1 offers the possibility of the flexible tube anywhere on its surface 2 by means of the Velcro material 21 or the velor or adhesive material 22 releasably secure.

The carrier 3 is made of a suitable material. Such materials may be constructed of wood, wood fibers, plastics (such as polymer based), polystyrene, or other suitable blending materials such as composites or biofibers. Also metallic materials, such as a suitable corrugated metal sheet, are possible. The choice of material depends turn from the concrete application, building codes and building standards.

Of particular importance, however, is that the flat carrier 3 has a certain dimensional stability. On the one hand, this makes it possible for the wearer 3 along with the foil 1 in appropriate sizes to deliver as finished panels to a construction site. On the other hand, with the carrier 3 and its material has a certain impact resistance. This allows a simpler and safer installation of the entire Velcro fiber board. The thickness of the carrier 3 is usually based on practical considerations and can, among other things, take into account daemon requirements.

Another advantage relates to an insulating material 6 over or on the flat carrier 3 or the Velcro fiber board is laid. The carrier 3 is designed so that no damage to the insulation and the insulation material 6 when laying the flexible pipe 2 can occur.

The Velcro fiber board can be supplemented by other functional layers.

In 1 is on the carrier 3 an elastic coating 5 Applied to the film 1 located. This elastic coating 5 is made of a flexible material, such as a plastic, styrofoam or foam. It is conceivable that the elastic coating 5 stuck with the foil 1 or connected to it by means of an adhesive. The elastic coating 5 gives way to external pressure due to its material properties, thus making it possible to compensate for minor bumps. At the same time causes an impressing of the tube in the film for fastening a larger bearing surface, so that a stronger Velcro connection between the tube and the film is created.

On a bottom of the dimensionally stable support 3 For example, there is a cover 4 , A function of this cover sheet concerns about a water protection, as by DIN 18560 T2 is defined. Again, the under the Velcro fiber board laid insulation 6 protected: In this case, it protects against possible pipe breaks and an associated water leakage from the flexible pipe 2 , The cover foil 4 can be stuck with the foil 1 or be connected to this by means of an adhesive.

The insulation material 6 Includes a material with low heat conduction and serves mainly the impact sound insulation. Typical materials include foamed plastics (polystyrene, neopor, polyurethane), foamed elastomers (neoprene rubber or rubber-like base materials), inorganic insulating materials (mineral wool, such as rock wool or glass wool) or natural insulating materials from renewable raw materials, such as wood fiber or wood wool.

The Velcro fiber board is placed in a room and on the insulation material 6 laid. By suitable cutting rooms can be completely enclosed despite different geometry.

With the help of the surface Velcro device is then the flexible tube 2 detachable with the foil 1 connected. This can be done by a single person without any additional special tools. Also subsequent changes in the situation or corrections are easily and quickly executed by this person. In this way, therefore, a flexible installation of a pipe system, for example, a floor heating possible.

The surface Velcro device allows a pipe laying on on the entire surface of the film 1 , In this way, a special flexibility is realized, which also has an advantageous stability of the laid pipes 2 offers. The flexible pipe 2 takes place, as it were, along the entire surface of the film 1 suitable adhesion points that make it detachable with the foil 1 connect. Due to the flexible detachable connections, the tube 2 as well as the carrier in almost any geometry will be laid without a pipe run would have to be defined in advance in a further step by means of suitable separate components or fasteners. Also, it is possible in a particularly simple manner to correct the pipe run by the connection is released.

Basically, it is also conceivable more than a flexible tube 2 to attach to the Velcro fiber board and so realize several heating or cooling circuits.

The elastic coating 5 allows some yielding in the attachment of the flexible tube 2 and thus serves the improved pipe fixation. Even minor bumps in the ground can be compensated.

In a further, not shown embodiment, the film 1 the Velcro fibreboard grid or similar geometries on which the orientation when laying the flexible tube 2 serve.

2 shows a Velcro fibreboard according to the proposed principle. The fabric-reinforced film 1 has an elastic coating 5 on mono- or multi-ply tissue, such as velor, plush, terry cloth or other textile fabrics made from almost perpendicularly crossed thread systems.

The fabric-reinforced film 1 or the elastic coating supports the way to a certain extent carrier 3 To the structural requirements, for example, in terms of footing and insulation behavior of the dimensionally stable support surface 3 to support. The reinforcement is the film 1 even more stable and thus assumes the stabilizing tasks of the wearer 3 , In particular, it is through the fabric reinforcement of the film 2 possible, the dimensionally stable carrier 3 to perform with smaller thicknesses.

Another advantage is that the fabric-reinforced film 1 is reinforced against traction. These occur above all after installation, as people move around on the laid heating or cooling system. Even in the room standing furniture lead to a certain permanent pressure and correspondingly acting forces. By reinforcing the fabric, the film is reinforced against this stress and thus contributes to the longevity of the laid pipe system and the Velcro fiber board.

3 shows a plan view of a Velcro fibreboard according to the proposed principle. Shown is a section of a tube 2 by means of the Velcro device 21 on the slide 1 is attached.

To install a heating or cooling system, such as a floor heating, a single person can bring several Velcro Fiberboard in a room. For this purpose, the Velcro fibreboards on the insulation material 6 laid or fastened and cut according to the geometry of the room. Single Velcro panel can be at their edges by appropriate devices, such as puzzle pieces, plugged together, but also just be juxtaposed. The flat design of the carrier plates with foil allows to line all room geometries and to make a decision about a laying of the tubes at a later time.

Depending on the room size and can have one or more flexible pipes 2 be moved. The flexible pipes 2 can be laid in a variety of geometries: as spirals, serpentine or in general, as required by the spatial form. The exact location of the flexible pipe 2 can be subsequently changed and corrected by a single person by means of the detachable connection of the hook and loop device, without the need for special tools or fixtures on the flat support 3 must be provided. The Velcro fibreboards can be connected to one another, for example by a meandering form, the edges of which intervene in respectively adjacent Velcro fibreboards.

In this way, a particularly simple and fast installation system is realized. Due to the high number of adhesive points of the Velcro device and the dimensionally stable flat carrier 3 lies the flexible tube 2 in a defined plane without significant height deviations. The Velcro fiber plate also allows through the film 1 and the Velcro device a stable pipe installation, which does not dissolve even by finishing with a screed.
