The invention relates to the field of construction and, more specifically, to a mounting element for mounting essentially straight, parallel parts heat conductor, in particular for floor element for a floor heating system or cooling. In addition, the invention relates to a method of manufacturing such an installation element, in particular a floor element.

Floor element according to the invention is designed to determine the paths, which would provide the correct mutual spacing between the different parts of the conductor circuit made with the possibility to supply heat to the room and accordingly discharge of heat from it. The conductor can be, for example, a heat-producing electrical cable or pipe, which transported hot or cold fluid. The floor element is covered with a layer are fixed under material to achieve essentially uniform distribution of the heating/cooling effect of the surface area of the floor.

Although the invention will be described with reference mainly to the so-called heated floor, it is obvious that this flooring system can be used also for cooling.

Known installation tool to install essentially direct, parallelizable heat conductor, contains the sheet that has at least one channel, and a layer of heat transfer material which extends along the one main surface of the sheet and on each side of the respective channels and forming open up the recess to accommodate heat conductor, and the upper side of the conductor is flush with the upper side of the sheet or below it, and the channels extend over the entire thickness of the sheet (see, for example, patent SE-B-468057).

Famous outdoor element has several shortcomings. For example, a plate made of a thick and hard to preserve the physical dimensions of the floor element. Due to the stiffness of the slab is impossible to lay ceramic floor directly on the aluminum plate of the specified element, or near it, due to possible cracking or weakening of ceramic tiles due to thermal stresses. The cost of laying the next layer on top of such floor elements is quite significant. In addition, the stove is expensive due to its required thickness. Due to the thickness of the plate cutting floor is a difficult operation. Moreover, the plate is relatively thick and expensive.

The present invention is the creation of the installation element, whereby fully or hour is ichno eliminated, at least one of the above disadvantages. Another object of the invention is to create an installation element, whose width can be minimized, for example, during transportation, and which provides a predetermined maximum width for these channels at maximum magnification, the width of the installation element. Another objective is to provide a method of manufacturing such elements.

The task is achieved due to the fact that in the installation element for installation essentially straight, parallel parts heat conductor containing sheet, which has at least one channel, and a layer of heat transfer material which extends along the one main surface of the sheet and on each side of the respective channels and forming open up the recess to accommodate heat conductor, and the upper side of the conductor is flush with the upper side of the sheet or below it, and the channels extend over the entire thickness of the sheet, the layer of heat transfer material consists of thin, easily bendable foil, the thickness of which is less than than 200 μm, and the other main surface of the sheet with one or more other thin films, which are mutually held together adjacent parts of the sheet formed by the ka is Alami, and which define the maximum distance between the parts of the sheet corresponding to the diameter of the conductor.

Preferably, through the installation element from the second main surface of the sheet until the first main surface of the specified sheet, except for the layer of heat transfer material, extends transverse slot, which forms a rotation between two mutually foldable parts of the installation element formed by the slot, with the adjusting element is designed for folding two slots for transportation.

Additionally, other thin film can be made flexible, and for transportation of the item can be made with the possibility of transverse compression with a connection between adjacent parts of the sheet which form the channels, while on the second main surface of the posted by line segments connecting the tape to overlap butt joints and thereby stabilize the installation of the element.

Another aspect of the invention is a method of manufacturing a mounting element for essentially straight, parallel parts heat conductor, in which is placed a group of separate, parallel portions of the sheet so that said parts are mutually parallel and spaced from each other at a selected distance in one plane, C is kreplach stretched flat foil of heat transfer material on one main surface of the group of parts of the sheet, then reduce the distance between the parts of the sheet to a selected value and to cause the holding thin film on the opposite main surface of the specified group parts list to determine the corresponding maximum channel width in the installation member, the width of the layer of heat transfer material between the adjacent parts of the sheet is chosen to ensure that the layer of heat transfer material is stretched by being around half the circumference of the conductor in the channel, while the conductor is placed between the two main surfaces of the specified element.

Preferably, the cut element from the one main surface, holding a thin film, until a layer of heat transfer material in the form of foil and fold the specified element twice at the place of incision, where the foil forms a rotation.

Preferably also applied to the flexible holding thin film, and then bring together part of the sheet is essentially a connection with each other, causing the segments connecting the tape to the other main surface of the group parts list for stabilization element, and cut the segments connecting the tape before installing the heat conductor in the installation element.

Thus, the installation element according to the invention the difference is between a known construction, however, instead of using a relatively thick and rigid aluminum plate, as in the known technical solution proposed in SE-B-468057, we offer a layer of heat transfer material consisting of easily bendable foil which has a thickness of less than 200 microns.

Due to the fact that the heat radiating foil has selected the free width between mutually adjacent polusobrannye parts bearing installation sheet item, you can press the heat-conducting conductor between the said strips and press the strips to the opposite sides of the conductor through aluminum foil; this foil covers essentially half the circumference of the conductor; and the specified conductor placed between the two main surfaces of the sheet. Part of the sheet may be mutually bonded before or after clamping of the conductor.

The use of relatively thin and easily bendable aluminum foil according to the invention makes it easy to find the size of the installation element by cutting the foil in the channel formed by the respective polusobrannye parts. You can easily reduce the width of the slot or channel.

The element according to the invention can be stored and transported in two different configurations.

In one configuration Prosobranchia part of the supporting sheet can be tightly compressed in erachem direction, when this excess foil in the slots or channels located in the gap of the connection or flat stacked on one main surface of the sheet. On the opposite side of the sheet on top of the connection strips can be glued pieces of masking tape to make installation element stiffness when bending in one direction around a longitudinal line passing. In addition, the sheet in its Central length portion can be conveniently divided by a slit, which extends transversely to the longitudinal axis prosobranch parts; this incision penetrates through the sheet almost to the heat transfer foil, which in this case forms a rotation around which the sheet can be folded in half, due to the above-mentioned segments of the tape specified sheet folded in half in this case constitutes a single product with sufficient rigidity for transport. The installation element can easily prepare for placement on a support surface, for which it is initially deploy tools around the corner, and then cut the sticky tape at the joints of the bands.

Essentially U-shaped and longitudinally extending channels in the sheet elements, in which is placed a knee conductors, can be pre-formed in the respective floor slab, which at its bottom side provided with a masking tape or foil, which UD is rivet together those parts of the plate, separated channels/slots. Thermally conductive foil, such as aluminum foil may preferably completely cover the upper surface of the floor plate.

In the installation element is usually placed mutually parallel, longitudinal sections, for example, the winding of the conductor, and the part of the conductor, curved 180°placed in U-shaped channels in the specified floor plate. Floor plate and mounting element can be connected to a heat transfer image by applying heat transfer foil, which covers the heat transfer foil plate and the specified element. The floor plate can be made using the sheet, which is a rectangular foam sheet, provided on one side (plastic) thin film, and on the other main surface of the heat transfer foil such as aluminum foil. Hot punch corresponding to the channels required for the curved sections of the guide, press on the side with aluminum foil in the direction of the plastic thin film, which is heat-resistant, whereby the foam form channels for space Explorer. Aluminum foil may be interrupted approximately at the inner radius of the channel, while the aluminum foil curves on the outer radius is the anal. If you wish to increase or strengthen the heat transfer, you can apply additional aluminum foil in the channels and along them. However, it is usually enough to bring warmth to those parts of the aluminum foil on the stove, which are located on the outer radius of the channel. The flat part, which are separated by channels that are physically held together by means of a plastic thin film.

Other advantages and features of the invention set forth in the following description of various embodiments of the invention, given solely as non-limiting examples and are presented in the attached drawings, which depict:

Figure 1 shows a floor element according to the invention essentially in transit. When using the element 1 has an essentially flat, rectangular shape and contains a layer 10 of a heat transfer material such as thin aluminum foil of appropriate size and thickness, which is less than 200 microns, preferably 100 microns.

The layer 10 of the foil is supported by the floor sheet 11, for example, mesh sheet, wood boards, gypsum Board, sheet and other Sheet 11 contains end-to-end, mutually parallel channels 12, made for example in the form of slots, which are also parallel to the longitudinal edges of the sheet 11. The slits divide the sheet 11 on mutually parallel, longitudinally extending part 13, for example, in the form of strips, the side strips of the sheet, respectively, have a width equal to half the width of the inside lanes.

The channels 12 are overlapped with parts of the foil 15 whose width is selected in accordance with the thickness of the sheet 11 and the outer diameter of the conductor placed in sections or parts of the foil 15, so that the foil 15 is tightly cover the lower half of the circumference of the conductor, the conductor can be located between the upper and lower main surfaces of the sheet.

As shown in figure 1, the sheet 11 may include a through transverse slot 16 in the Central along the length of the part is the same whereby the connecting part 17 of the foil to form a rotation for both parts of the floor element.

On the back side of the sheet, the gap between the parts 13 are overlapped with bilateral amplifying thin films 77, made for example in the form of sticky tape 77 or any appropriate means, the tape 77 determines the maximum distance between the parts 13, in respect of which well matched the width of the foil 15 for grasping the pipe/conductor whose diameter corresponds to the greatest width between the parts 13. Of course, alternatively, the sticky tape 77 the gap between each pair of parts 13 can be positioned a thin film that completely covers the underside of the leaf.

Sticky tape 77, respectively, should have this flexibility, in order to minimize the width of the element by bringing together the side edges of the mutually adjacent parts 13, for example, during transport.

After distributing element 1, shown in figure 1, the specified item can be placed in the correct position on the black floor, with part 13 of the sheet is attached to the floor by stretched in the center of the adhesive tape 77. Now you can easily and correctly to push the heating cable/heating conductor/cooling conduit in the channels that are open after the removal ol the interstitial holders.

As shown in figure 2, the adhesive tape 77 may be replaced by an adhesive thin film that covers the corresponding main surface of the floor element. Of course, you need to cut the foil in the rotary joint.

Figs.4 and 5 show a variant embodiment of the invention, in which part of the foil 15 are folded together and laid flat on one main surface of sheet 11, while the portion 13 of the sheet transversely brought together in contact with each other. The hard condition of the item during transport through segments sticky, connecting tapes 34, 35, which block the channels 12 on the main surface, remote from the aluminum foil, the channels 12 are eliminated by compression of the strips to each other, and is achieved by folding element twice in a transverse slot located, for example, half the length of the sheet without penetration through the layer 10 of aluminum foil. After folding the sheet around the means of turning and cutting the connecting strips 34, 35 at the location of the channels 12 can place the sheet on a support surface and mutually separate lanes for disclosure channels 12 through which can be decomposed Explorer and pressed a piece of foil 15 in the channels.

As shown in Fig.7 and 8, the conductor 4 is usually laid sinuously, with mutually prima the surrounding, straight and parallel parts 45 are stacked in mutually adjacent clad foil, the corresponding channels in the element 1. Bends or elbows 41 of the conductor 4 is also placed in the channels 32 in the plate 30. As shown in Fig.7, the channels 32 typically have a semicircular shape, so that the ends of the channels 32 are connected with adjacent channels in the list.

Although the invention for simplicity described above in relation to outdoor construction, it is obvious that the invention is not limited to this particular case of application, and can also be applied to the use of the element and plate according to the invention on the surfaces of walls, ceilings or other surfaces for heat supply to these structures or removal of heat from them.

As shown in 6, 9 and 10, sheet 1 figure 1 can be made by moving along the path of feed of many plates, spaced transverse intervals, with the first part of the path plate are mutually separated from each other (figure 9) by means of an intermediate element 81. In the shown case, the intermediate elements 81 in the form of wheels of a certain width, through which concatenate the layer 10 of flat aluminum foil on one main surface. Then part 13 transversely reduce to a smaller distance between them using intermediate elements 82, which in the shown case the e is made in the form of wheels, pressing the aluminum foil in the channels, and then, on opposite sides of the parts 13 across channels 12 put pieces of the flat adhesive tape 77 for the formation of the largest channel width corresponding to the diameter of the conductor. The first referred to the width of the channels is chosen so that the conductor on its semicircle could be covered with aluminum foil and to simultaneously provide a space for the conductor between the main surfaces of the sheet.

In the absence of the heat-conducting foil in direct channels, but where such foil is desired, a conductive tape, in principle, can be performed in accordance with figure 5, the position 15'. The tape can be obtained either with glue and paper substrate, or only with adhesive on all or parts of the bottom surface of the formed foil, preferably on the two outer parts of the outside of the folded part. Folded in half, the part will be less than the width of the protruding part, and, thus, can be used particularly easily. During indentation of the conductor in the channel strip will automatically be U-shaped and cover the conductor, at least around half of its circumference.
