German Vortex GnIbH ₇ 7141 Aldingen near Stuttgart Pipeline for underfloor heating

The invention relates to a pipe mat, e.g. for floor, ceiling or wall heating made of flexible Material with pipes bent in a meandering shape to form coiled pipes, each pipe loop being made up of bends and straight parts.

The pipes used for underfloor heating are either made of metal pipes or plastic pipes outside the house, bent into a tube coil mat and then inserted into the room or else molded in place and attached to the ground. Also tube mats made of meandering pre-bent tubes that are connected to sheet metal strips extending over the entire length are known. In all cases it is The amount of work involved in installing underfloor heating is very great, and it also requires the production of such pipe coils significant manual skills.

The disadvantage in the production of plastic pipes is that plastic pipes for a given diameter-wall thickness ratio allow only relatively large bending radii, so that the pitch of the coils is very large. Per Only a relatively small amount of pipe can thus be accommodated in the unit of area of the floor. This leads to given thermal area performance leads to relatively high water temperatures, which in turn has negative effects

have on the aging resistance of the plastics. If small bending radii are to be used Hoses with very large wall thicknesses are required. These not only lead to high costs, but also have a particular effect strong isolation. The use of sufficiently thin-walled hoses is therefore only possible with large ones Bending radii.

The invention aims at a tube coil mat in which the required tube length per unit area of the floor can be carried out with larger bending radii than before.

The invention solves this problem in that adjacent arches are connected to one another by connecting elements are. According to the invention, the pipe to be laid in the floor consists of a pipe that is already in the form of a coil of a relatively small width, e.g. 1 meter, bent pipe, which is held by at least one holding device, e.g. B. a steel spring strap, is kept at a distance. This makes it possible to deliver the pipe coil in a rolled form about an axis parallel to the extension of the width. The installer then only has to lay out the role, cut it off at the end and other roles next to it spread out. Another improvement is that two pipes are laid directly next to each other, so the pipes are laid bifilar.

The invention is to be described with reference to figures.

Figure 1 shows an embodiment according to the invention. Figures la and Ib show sectional detail perspectives. FIG. 2 shows the tube, a holding device and the spring band running along the extension.

which can be seen the connection of adjacent sections to form a mat. The tube 3 is bent in loops, its Elbow areas 41 touch. Clamps 40 (FIG. 1a) or in the case of bifilar hoses are provided around these elbow areas Clamps according to 43 (Figure 1b) arranged.

FIG. 2 shows another type of fastening, in which steel strips 1 running parallel to the floor are provided which sheet metal clamps 2 are pushed that clasp the plastic pipes 3. These bells are along the strip 1 displaceable and allow a sufficient distance to the floor 4. ■

Claims (2)

Claims M.J pipe mats, e.g. for floor, ceiling or Wall heaters made of flexible material with pipes bent in a meandering shape to form coiled pipes, with each pipe loop consists of arches and straight parts, characterized in that adjacent arches (41) through each other Connecting elements (40) are connected. 2. Pipe mat according to claim 1, characterized in that that the connecting elements simultaneously form the fastening elements of the mat on its base. 609837/0319 Le first page
