Description:

The invention relates to a plate for laying heating pipes of underfloor heating, in particular baffle plate for the arched guiding of the heating pipes, consisting Made of a solid plate body with a rectangular shape, the grooves open on the top for embedding the heating pipes having.

For laying the heating pipes for underfloor heating Panels of the type mentioned are used in which the panel body due to its choice of material impact sound and thermal insulation as well as step resistance guaranteed and has grooves in which the heating pipes to be laid, which usually consist of plastic or copper, can be fixed. Most of the floor space is filled with parallel heating pipe runs, but are on two opposite walls and especially at the corners, deflections and return lines of the heating pipes to connection points are necessary. For this Until now, there have been deflection plates and distributor plates for purposes. Such deflection and distribution plates are also used for floor surfaces required that deviate from a clear square shape and projections, bay windows or the like. Include.

A plate of the type mentioned above, which is also disclosed in DE-GM 81 07 402, is known for this purpose.

This document discloses a plate which has a connecting part and a deflecting part. The deflection part has two grooves running in the longitudinal direction of the plate to accommodate the heating pipes and the baffle is with numerous triangular, rectangular, circular and quarter-circle-shaped elevations fitted in such a way that they are in extension the grooves of the connecting part running parallel grooves, furthermore at a distance from the grooves of the connecting part Running two transverse grooves, one circular in the middle and four quarter-circular grooves at each of the four corners Forms grooves. The quarter-circle and circular grooves run parallel to the axes of the two mutually extending grooves that cross each other at right angles in the deflection plate.

The distribution and deflection possibilities of this known plate are very limited. Do you want something because of the achievement A uniform temperature profile has been strived for so far, as well as the mutual spacing of the heating pipes in the area of the deflection and distribution plate at any point, in this known design either only once using the circular central groove or once each using one of the quarter circular grooves are deflected. Further curves and connection options are then used up.

The known plate has, at least in the connecting part, grooves with an omega-shaped profile in cross-section, so that the heating pipes can be firmly locked into the grooves. A metal lamination on the surface creates a Heat conduction achieved, which a uniform temperature distribution guaranteed. A special stiffening, i.e. H. However, the metal cladding does not have a reinforcing effect. As a result, the deflection parts of these known panels are quickly and easily damaged during the laying work are, in particular, the triangular small elevations are very easily crushed, deformed, broken off o. The like. In addition, the production of such a shaped plate is cumbersome.

If you want the steering part alone with the well-known record use what, in common cases, is necessary to repatriations To create the underfloor heating pipes, the connecting parts of the deflection parts along a predetermined break or Dividing line to be divided. The disks used in this way are very large without any expansion the laying and deflection options is created.

The invention is therefore based on the object of a plate to create the type mentioned, which offers a much larger number of deflection options, mechanically is more stable than known designs and can be manufactured more easily, especially during the laying work.

To solve this problem, a plate of the type mentioned is characterized according to the invention in that the aspect ratio of the rectangular shape is 1: 2, that a square deflector and a square connector are provided, wherein the grooves in the connecting part are arranged to run parallel and in a straight line, while the deflecting part has equidiametral, full half and quarter krexsförmxge elevations, each of which at the points of the smallest mutual distance approximate to a distance corresponding to the width of the grooves, and that. the grooves in the connector run parallel to the long, rectangular side, with a groove on the Longitudinal center line of the rectangular shape and each left and right next to this one further groove, their Center is arranged at a distance corresponding to a third of the short side of the rectangle, and that the diameter of the circular and part-circular elevations of the deflection part, a third reduced by the width of the groove corresponds to the short side of the rectangle, the deflection part corresponding to the groove division of the connecting part its edges have two semicircular elevations in the middle and quarter-krexsförmxge at the corners Has elevations, while four circular elevations are arranged in the middle, the centers of which the intersection points of lines parallel to the edge, which the Centers of opposite semicircular elevations

connect gene, and that at least the grooves of the connecting part, if necessary. Also the gaps in the area of the zones are largest mutual approach of the circular and part-circular elevations of the deflection part an omega-shaped Have cross-section.

In the plate designed according to the invention are per se known and new measures in a surprisingly advanced manner with surprising inventive results united. Due to the fact that the deflection part has sufficient part-circle or circular elevations and no knob-shaped, Has triangular elevations, the desired stability and resistance is in the Laying work as well as the simplicity of manufacture are guaranteed. Because the connector not as known two, but three longitudinal grooves and the deflection part of this groove division arranged accordingly Bearing elevations, many times greater deflection possibilities are created. It can be in any Form not just one, but three arch guides of the heating pipes can be laid at the same time without the heating pipes come closer than in the connection part. In addition, there are also many other laying options by using the semicircles and quarter circles given on the edges. In most cases, you can therefore come without having to separate the deflector

with the plate and can implement all laying patterns.

There is a previously unattainable effect of the new plate in that the heating pipe grid, d. H. So the distance between the heating pipes due to the shape of the room can be changed as required. This possibility is to achieve an ideal temperature profile underfloor heating is of vital importance. When choosing the installation spacing of the heating pipes, which was previously As already mentioned, the entire floor area was the same size, it was ignored that a room with four walls in the extreme case with all four walls can border on four different temperature zones. So can For example, a room wall can be an outside wall that is extremely cold in winter, the second wall can be attached to one Adjacent cold room, e.g. B. a stairwell that is not heated is, a third wall to a normally heated adjoining room and the fourth wall z. B. to a room that is excessively warm due to commercial use or the like. Due to the design or spatial shaping of the invention formed plate can meet these different boundary conditions by changing the installation grid of the heating pipes, d. H. thus change in the mutual distance, must be taken into account. On extremely warm walls or In the vicinity of such walls, the installation spacing can be selected to be large and accordingly small on extremely cold walls.

This advantage has not yet been achieved in any known panel for laying underfloor heating. That the Plate designed according to the invention for laying heating pipes is excellently suited in a uniform grid does not need to be emphasized 2. ^. will.

Merely for the sake of completeness, it should be pointed out that in Handbuch 77 from Wärmetechnik GmbH, Duisburg, a distribution plate VPH is shown on pages 8 to 15, in particular on page 12, bottom right, the square plan in the middle six parallel arranged circular elevations, two on two edges semicircular and at the corners each have a quarter-circle elevation. The distances between these elevations of each other are a multiple of the diameter of the circles and partial circles and are flawless Fixing of underfloor heating pipes naturally not suitable. In addition, this plate offers because of the space-shaped Distribution of the elevations also does not allow the connection possibilities like the plate designed according to the invention.

According to claim 2 it is provided that the plate between the deflection part and the connection part has a predetermined breaking or dividing line having.

With this measure, it is possible in exceptional cases to implement feed-ins and other special measures.

According to claim 3 it is provided that the plate body made of heat and impact sound absorbing foam, e.g. B. Polystyrene rigid foam is made of and is provided with a metal lamination on the top, which both extends over the groove surfaces as well as the flanks of the elevations or the surfaces of the spaces.

On the one hand, the metal lamination ensures reliable heat transfer from the heating pipes to the plate surfaces achieved and a perfect temperature distribution over the surface is guaranteed. Simultaneously the rigid foam offers the necessary step resistance, impact sound insulation and thermal insulation down.

In another further development of the one designed according to the invention Plate is provided that the plate body on its underside, at least in the area of the deflection part, is provided with a base plate, which is a sandwich panel with a middle layer of rigid foam, such as. B. Rigid PVC foam, and an upper and lower layer Metal or fiberglass (GRP) is formed, with the upper and lower layers of either the same or different materials.

In this development, on the one hand, particularly high mechanical strength is ensured when the base plate At least one outer surface is made of GRP, and there is also an additional safe Impact sound insulation and heat insulation as well as harmonic distribution ensured, with the insulation from the middle layer of rigid foam and the heat distribution is achieved by the metal layer that may be used.

Use of the plate designed according to the invention.

The figures show a plate 1 for laying heating pipes 2 for underfloor heating. The plate 1 has a rectangular shape with an aspect ratio of 1; 2, for example 50 cm: 1 m, and is in a connection part 3 as well a deflecting part 4 structured. Connection part 3 and deflection part 4 are separated by a predetermined breaking line or dividing line 5 designed separable from each other.

The connecting part 3 of the plate 1 has three grooves 6, which run parallel to the long side of the rectangle. The middle groove runs on the longitudinal center line of the Rectangular shape while the "two outer with their center have a distance from the longitudinal center line or center of the central groove, which is expediently one third corresponds to the short side of the rectangle. The distance of the outer grooves from the edge, i.e. H. the long side of the rectangle, is about a third of the short side of the rectangle.

The deflecting part 4 contains four circular elevations 7 in the middle and a quarter-circle at each of the four corners Elevation 8 and in the middle of the four edges two, with the spacing of the grooves 6 arranged to match semicircular elevations 9. The circular, semicircular and quarter-circular elevations 7, 8, 9 have the same Diameter. The diameters of the circular elevations lie on the intersection points of lines which form the Centers of the semicircular elevations 9 opposite

Connect lying sides of the connecting part 3 with each other. The common diameter of all circular and part-circular Elevations 7, 8, 9 correspond to a third of the short side of the rectangle, reduced by the width of one Groove 6. In this way, all circular and part-circular approaches Elevations 7, 8, 9 in the connection part 3 in certain zones to one another in such a way that they with their flanks define the groove distance of the grooves 6. This approximation creates gaps to define the heating pipes 2 created.

The structure of the plate 1 can be seen in FIGS. It can be seen that the grooves 6 in cross section are omega-shaped so that the heating pipe 2 can be pushed in through the upper opening and then is set in the respective groove 6. This omega shape of the grooves can also be applied to the areas of greatest approximation the circular and part-circular elevations 7, 8, 9 of the connecting part 3 are expanded, if at least in that Area of approach, the flanks of the elevations 7, 8, 9 are designed according to the omega shape.

The width of the grooves depends on the diameter of the pipes to be laid. You can z. B. 10 or 16 mm and, if necessary, also depends on whether plastic or copper pipes 2 are laid.

The plate body of the plates 1 normally consists of a heat and impact sound insulating, also step-resistant Axle foam, like polystyrene, possibly also PVC. The top of this plate body of the plates 1 is at the simple embodiment according to FIGS. 2 and 4 as well as in the embodiment according to FIG. 3 with a glued-on metal lamination 10 provided. This metal lamination 10 extends extends over the surfaces of the grooves 6 and it also covers the flanks of the circular and part-circular Elevations 7, 8, 9 and the spaces between the elevations, so that the heating pipes their Can transfer heat well on all sides.

An improved version of the plate 1 is shown in FIG. This version is on the underside of the plate body of the plate 1, a base plate 11 is glued, which is itself designed as a sandwich panel. The bottom plate 11 has a middle layer 12, which consists of a rigid foam, for example made of PVC, while the upper layer 13 and the lower layer 14 are made of Glass fiber reinforced plastic or metal can be made. Both layers 13, 14 can consist of GRP, it can but also the lower layer 14 on GRP and the upper layer 13 made of metal, such as aluminum, and vice versa. The base plate 11 increases the mechanical strength, the impact sound insulation and thermal insulation and especially when a layer of metal is

stands, also the heat distribution. This considerably improves the technical properties of the plate 1. When you want to work particularly economically and still achieve optimal technical properties should, then only the Umlenkteix 4 with a cross section according to FIG. 3 and the connecting part 3 can be provided with a cross section according to FIG.

pie Figures 5 and 6 show the laying examples of heating pipes 2 using the plate 1. It is to see that in Figure 5 on three outer walls of a room, the heating pipes 2 at a close distance from each other . run, while they have a greater distance in the central area.

In the exemplary embodiment according to FIG. 6, the installation distance of the heating pipes 2 is on two opposite sides Walls are particularly narrow and wide in the central area, while for the two other opposing walls no special laying measures are required because these walls z. B. adjoin neighboring heated rooms.

The examples according to FIGS. 5 and 6 can be varied vary and, in particular, extend to structured rooms. As an essential aspect of the invention but consists in the fact that for the first time different

spacing between the heating pipes is possible Example, reference is made exclusively to these laying examples.

In. In many cases, the metal cladding 10, the preferably made of copper, at least within the Grooves 6 provided with a thin plastic coating as a sliding layer to prevent wandering and expansion noises suppress that caused by the cooling and heating of the heating pipes 2 or by the associated changes in length and creeping movements occur within the grooves 6. In many cases, the plates 1 is a Metal plate or foil applied before the usual floor structure, if necessary with screed or intermediate layers and glued carpeting, etc., is carried out. For the further Design of the floor structure above the panels 1. The invention does not require any restriction, which is why these details are also not specifically shown.
