webs 11 for the heating pipes 8 provided. You have the task of placing the heating pipes 8 above the rest To keep the level of the surface of the element, so when pouring the built-in elements in the screed this can completely enclose the heating pipes 8. This creates good thermal contact.

The installation of the elements for liquid surface heating is as follows: The built-in elements are placed over the entire surface of an existing concrete ceiling. For comparison The plate 1 is cut along the webs 11 of the dimensions available on site. Form thereby the support webs 11 in addition to the support tasks also a visual aid for dividing the panel. The craftsman on site is thus one further ease of work given. He also has the advantage that a cut through the Plate practically guided through a homogeneous material will. Should a cut be made straight through a holding device 2, this can be unscrewed.

After covering the concrete ceiling with the installation elements, the heating pipes S are laid on them by

pressed into the holding devices and held by their jaws. After connecting and Defining the heating pipe 8, the liquid screed can then be poured on. After the The floor can be walked on with the screed.

For use in so-called dry construction or in prefabricated house construction, it is necessary to use the built-in elements to be used in another embodiment. In these buildings, a load-bearing ceiling layer, For example, made of concrete, another floor layer applied, for example, from a consists of thin chipboard with a carpet coating. Pouring with screed is not intended. For this case is the embodiment according to Fig. 2a / b used. With this built-in element, numerous stools 13, 14 are provided, distributed over the area, which also adapt in size to the grid dimensions, as is the case for the built-in element according to FIG. 1 is provided. Numerous, square humps 13 or half-format stools 14 are distributed in such a way that that in each case free lanes 15, 16 are left open, in which a heating pipe 8 is laid & ann. The same holding devices 2 as in FIG. 1 are provided here. This is done on support bars

other plates are installed than those which have been described with reference to FIGS. 1a / b and 2a / b.

All holding devices 2 or 20 or 20 'have in common that they consist of a base 21 (or 21', 21 ¹¹ ) with an upright rim 22 which is provided with two by two opposing recesses in such a way that two around 90 cross paths are created for the heating pipe to be inserted. In this case, according to FIG. 3, an element is selected which consists of a wide foot piece which is formed in the form of a ring from which four fingers 23 protrude upwards and are distributed rotationally symmetrically over the base

and are provided with a curved, resilient end portion which faces the center of the base. Between the fingers 23 each result in the recesses.

The heating pipes 8 are clamped in these recesses. In this case, recesses lying opposite each other in alignment, with two crosswise by 90 arranged paths for the heating pipe to be inserted are given.

According to Fig. 1b, the base 21 of the holding device is embedded in the Styrofoam foam mass, which is vorzugaeise happens directly when the plate is foamed.

However, it has been found to be useful, initially when transporting and storing the built-in elements to refrain from installing the holding devices. These are only in the form of the holding devices 20 subsequently inserted into prefabricated depressions 25 and glued there (FIG. 4). The holding elements 20 according to Fig. 4 accordingly consist of similar fingers as in Fig. 3, but the base consists of a simple, cylindrical ring which can be inserted into a corresponding circular recess 25. Included are the wells in the plates supplied?

act. When installing the panels, the holding devices plugged in there. This has the further advantage that when installing the heating pipe 8, in which not all holding devices 20 are used, they do not even have to be installed, so that there is another cheaper effect.

Finally, FIG. 5 shows a further holding device 20 ′, which consists of a The basis is similar to that of FIG. 3. The wreath on top is, however, with a center screw 26 held so that the wreath can be rotated as required and then screwed is.

The choice of materials for the actual plate and for the holding devices is essentially based according to the requirements of the building regulations. In addition to organic plastics, inorganic, such as rock wool or pressed minerals are used as the material. The holding devices are preferred made of plastic. However, it is also possible to manufacture the holding devices from metal. The anchoring of the heating pipes 8 takes place by snapping the pipe into the recesses, the latter being

are to be measured that they reach over with their fingers 23 somewhat over the greatest width of the pipe 8. Included it is possible to simply push the heating pipes into the recesses or let them snap into place.

However, it is also possible to deviate from this design by inserting the tubes into the recesses and additionally attached.

Another advantage is that the holding devices 2 can each be colored differently. 6 shows schematically a covering of a room composed of many elements 1. This results in different rows of holding devices 2 colored red and blue, shown here by crosses. The special arrangement in staggered form as a regular grid, in which each four holding devices of one color - exactly centered between them include a holding device of a different color, makes it possible that when designing the flow pipes 8 'only red holding devices and the return pipes 8 ¹ 'only blue ones can ever be used. This makes the laying work much easier.
