Said panel comprises a flat rectangular base body (1) and cavities for accommodating thermal conduits (3). The cavities are configured as a grid-type arrangement of channels (2), consisting of several intersecting, rectilinear channels (2.1.1, ..., 2.1.n; 2.2.1, ..., 2.2.n) that run parallel to the lateral edges, several rectilinear channels (2.3.1, ..., 2.3.n; 2.4.1, ..., 2.4.n) that likewise intersect and run diagonally and at least two rows (R1, R2) of arched channel sections (2.5.1, ..., 2.5.n), positioned mirror-symmetrically, the vertexes (S) of said arched channel sections facing towards the lateral edges and the respective ends (18.1, 18.2) of said sections being connected to the rectilinear channels. The intersecting channels (2.1.1, ..., 2.1.n; 2.2.1, ..., 2.2.n) that run parallel to the lateral edges (11.1, ..., 11.4) are located at equal distances (A) from one another. The channels running diagonally intersect at intersection points (P1), said channels are equidistant (D) - measured diagonally - from the intersection points (P2) of the channels that run parallel to the lateral edges. The invention also comprises a surface heating system, such as an underfloor heating system, containing at least one modular panel and at least one thermoconductive sheet element.

Description

Modular laying plate for laying in floor or wall heating systems and heat conducting plates

The invention relates to a modular laying plate made of thermally insulating material, such as polystyrene foam, for laying in floor or wall heating systems, comprising a rectangular flat base body and cavities for receiving heat conduction pipes, with at least one of the side edges of the flat base body all over The length is graded to enable a fold connection between two installation panels. Furthermore, the invention relates to a surface heating system with modular installation plates and heat-conducting plate elements, each of which is to be placed on the installation plate with at least one wing part and which are provided with a recess to be engaged in the cavity.

From DE 77 29 992 Ul and DE 73 24 964 Ul a laying system is known which consists of several so-called head plates to be laid in the base areas and several middle plates with preformed troughs. The top plate has a tennis racket-shaped configuration of the trough, which ends in short, straight trough sections. Again, straight troughs are arranged on the middle plate. The disadvantage is that two types of slabs have to be used for laying. DE 81 07 402 Ul shows a laying plate with heat-conducting sheet elements. The heat-conducting plate element also has a trough for insertion into the cavity of the laying plate. The cavities of the laying plate are characterized by a U-shaped cross-section, whereas the trough of the heat-conducting sheet element is Ω-shaped. It is disadvantageous that, due to the thermal stresses, the heating pipes are deformed and the heat-conducting sheet elements can therefore tend to jump out of the U-shaped cavities of the laying plate. It is also disadvantageous that, after laying, a cavity is created between the floor and the thermally insulating plate element, which can cause an undesirable “drum effect”.

The object of the invention is to design a universal installation board which is particularly suitable for dry installation and which can be used both in the edge or base regions and in the middle region of the floor or the wall in between. The new laying plate is also intended to provide various options for laying the heat pipe, e.g. enable a diagonal, spiral or meandering course. Another object of the invention is to provide a heat-conducting sheet metal element which can be better held in the cavities of the laying plate.

This object is achieved by a modular laying plate of the type mentioned at the outset in that the cavities are designed as a grid-like channel arrangement which consists of a plurality of straight, intersecting channels, each running parallel to side edges, and a plurality of diagonally intersecting channels the cavities are designed as a grid-like channel arrangement, which consists of a plurality of crossing, rectilinear channels, each running parallel to side edges, a plurality of likewise crossing, diagonally running, rectilinear channels and at least two rows of arched channel sections lying in mirror image to one another, where the arched channel sections are directed with their apexes to the side edges and their ends are each connected to the rectilinear channels, so that the intersecting channels running parallel to the side edges are each arranged at equal distances from one another, the first and last, before the Channels running along the side edges are each half a distance from the respective side edge, and that the diagonally running channels intersect at intersection points that are measured at the same distance - diagonally dimensioned - from the intersection points of the parallel to the se edge channels are removed.

The advantage of this configuration is that several panels can be laid next to each other in the same grid-like channel arrangement without having to use special top and middle panels.

The diagonally running channels preferably intersect at intersection points that are at the same distance - measured diagonally - from the intersection points of the channels running parallel to the side edges. This results in a denser arrangement of the inclined channels and thus one achieved better variability in the laying of heat pipes.

It is important that the ends of the arcuate channel sections connect to the intersection of the channels running parallel to the side edge. This enables a smooth transition of the arcuate channel section into the straight-line channels arranged both obliquely and parallel to the side edges.

, Is of particular advantage that least two mirror images of each side rows are incorporated by arcuately extending channel sections on the installation plate little ^¬. This results in several options for laying heat pipes, which can be routed in practically all directions and in all conceivable configurations. Rectangular flooring panels measuring 100 cm x 60 cm to approximately 120 cm x 60 cm are normally brought onto the market. In addition, it is expedient to arrange the arch sections on the narrow sides of the laying plate. It is also possible to produce square plates, on the four sides of which a series of curved sections is inserted. Finally, it is conceivable to use webs to be rolled out instead of the individual plates, on which the grid-like channel arrangements already described are incorporated.

The grid-like channel arrangement is preferably designed as a mirror image of a transverse and a longitudinal axis of the laying plate, the transverse and longitudinal axes crossing at a geometric center of the channel arrangement. This configuration betönt the variability of Verlegeplat ^¬ te.

All of the above-mentioned channels can each have a semicircular, Ω-shaped or trapezoidal cross section which tapers towards the surface of the laying plate, in which the two mutually facing edges of the channels are preferably gently rounded and each have a height which is approximately 10% to 35 % of the total depth of the channel.

Furthermore, corners can be formed by the intersecting channels of the laying plate, each of which has a gently rounded thickening.

Due to the special design of the edges of the channels and the thickening of the corners, the heating pipes and / or the heat-conducting plates can be pressed into the laying plate in such a way that the material of the laying plate is not damaged, in particular is not torn.

The laying plate according to the invention is preferably made of a rigid foam, such as rigid polyurethane or polystyrene foam. Other materials, for example plaster (in particular for wall heating) or integral foams, are also suitable as material for the production of the installation boards. In the case of a laying plate made of integral foam, the upper layer, that is to say with channels, can be set harder than the lower layer. In this way, improved impact sound insulation can be achieved.

The laying plate according to the invention can also be manufactured in a sandwich construction. It is expressly noted that the laying ^¬ plate according to the invention, both for heating, can be used as well as cooling systems.

Furthermore, the invention relates to a floor or wall configuration, which is constructed from laid panels, and to a surface heating system, such as an underfloor heating system, which comprises: - at least one already described modular laying panel, - and at least one heat-conducting sheet element, which has at least one wing part of the laying plate and that is provided with a recess to be inserted into the channel, the laying plates and / or the heating element being covered with dry screed plates or embedded in a bed or mortar or screed, and the heat pipes in any configuration, how to lay in a meandering and / or diagonal and / or spiral configuration.

The trough of the heat-conducting plate element is preferably slightly wider than a distance between the two opposite edges of the channels, so that when the trough is pushed into the channel, its edges can diverge due to the elasticity of the material of the laying plate and can press against the trough.

The trough of the heat-conducting plate element can be rounded or / and fluted at at least one of its free ends. In order to simplify the production and laying of the heat-conducting sheet metal elements, it is proposed that these are initially designed as one-piece heat-conducting sheet metal strands. The individual heat-conducting sheet elements can be cut to length from the one-piece heat-conducting sheet strand by kinking at its predetermined breaking line. Recesses can be machined at the predetermined breaking line, which preferably run transversely through the trough peripherally.

Furthermore, stiffening beads which are preferably arranged on the predetermined breaking line can be introduced on the heat-conducting sheet element or on the heat-conducting sheet strand outside the trough.

The heat-conducting plate element can also be designed as a deflection plate with an approximately semi-circular arc-shaped trough for receiving a heat-conducting tube bent into a loop.

The deflection plate preferably has at least one holding element to be clawed into the respective laying plate, which has been created, for example, by bending along the side edge or by bending a material section of the deflection plate projecting beyond the side edge.

In another embodiment of the heat-conducting sheet element, the trough can have at least one bead which reduces its cross section and which is arranged in the upper trough region, preferably on an outer trough edge, and which enables the heat pipe to be inserted into the trough to be snapped into place. It is of particular advantage that both the modular ^laying boards and the heat-conducting sheets according to the invention can be installed by a non-specialist. It is not necessary to pay attention to a special arrangement of the laying plates, since the top and middle plates have been replaced by plates of a single type.

FIG. 16 shows the heat conducting sheet strand according to FIG. 15 in end view, and FIG. 17 shows the heat conducting sheet strand according to FIG. 15 in a top view of its flat side.

In Figures 1 and 2, a molded foam, suitable for laying in underfloor heating systems made of polystyrene foam is shown, which has a rectangular flat base body 1 and cavities for receiving heat pipes 3. The laying board 100, hereinafter referred to as "board", has dimensions of 1020 mm x 645 mm and a total thickness D = 22 mm, which is still approximately 3 mm smaller than the thinnest boards available on the market.

Two adjacent side edges 11.2, 11.3 of the plate are each equipped with a step fold 8, 9 (see FIG. 2) and the remaining side edges 11.1, 11.4 are also each compatible with a step fold 16, 17, so that the modular plates 100 are interconnected can be connected, as shown in Fig.6a.

The cavities accessible from above are designed as a grid or lattice-like channel arrangement 2, which consists of a multiplicity of intersecting ones, each parallel to side edges 11.1, 11.3; 11.2, 11.4 straight channels 2.1.1 2.1.n; 2.2.1 2.2.n and several intersecting, diagonally running, straight-line channels

2.3.1 2.3.n; 2.4.1 2.4.n exists. The channel arrangement 2 also includes two rows Rl, R2 of arc-shaped

Channel sections 2.5.1 2.5. , Within the described

Channel arrangement 2 are triangular, semi-lenticular and approximately trapezoidal elevations 4, 5, 6 and 7 of the same height, delimited from one another by the channels. As shown in FIG. 1, the channel arrangement 2 is designed as a mirror image both with respect to a transverse axis L and with respect to a longitudinal axis K, the two axes determining a geometric center M of the channel arrangement 2.

The channels 2.1.1 2.1.n running parallel to the side edges 11.1 11.4; 2.2.1 2.2.n are each the same

Distances A are arranged from one another, namely bidirectionally, i.e. in both directions determined by the adjacent side edges of the plate. The first and the last channels lying in front of the side edges are each half a distance from the respective side edge.

The arch-like channel sections 2.5.1 2.5.n, hereinafter referred to as "arches", are each directed with their apices S onto the side edges 11.2, 11.4 (narrow sides of the plate), the ends 18.1, 18.2 of the arches each at intersection points P2 of the channels running parallel to the side edges 2.1.1 2.1.n; 2.2.1 2.2.n are connected. The elbows are expediently located between the first and the second channels 2.2.1 and 2.2.2 or 2.2.n-l and 2.2.n, which run parallel to the narrow side, so that an inlet pipe can be laid in a straight line.

Furthermore, it can be seen in Fig.l that the channels 2.3.1 2.3.n; arranged obliquely at an angle of 45 °;

2.4.1 2.4.n cross at intersection Pl, each at an equal distance D - measured diagonally - from the intersection P2 of the channels 2.1.1 2.1.n running parallel to the side edges 11.1 11.4; 2.2.1 2.2.n are removed. All channels 2.1.1 2.1.n; 2.2.1 2.2.n;

2.3.1 2.3.n; 2.4.1 2.4.n and 2.5.1 2.5.n have an Ω-shaped cross section Q1 (see FIG. 4) tapering in the direction of the surface 10 and a depth T which corresponds approximately to the outer diameter of the heat pipe 3 , The approximately teardrop-shaped cross section Q1 allows the heat conduction pipe 3, which is made of polyethylene, to be easily pressed into the channel and ensures a good hold. It can also be seen from FIG. 4 that the channel has two opposite, reinforced edges 29.1, 29.2, which are gently rounded and raised. The height h of the edges 29.1, 29.2 in the present case is approximately 30% of the depth T.

At the side edges 11.2, 11.3 of the plate, which run out to a corner E, there are bores 14.1, 14n and at the rest

Side edges 11.1, 11.4 projecting knobs 12.1 12.n (cf. in particular FIG. 3) provided for the bores are provided. The height of the knobs 12.1 12.n corresponds to the depth T of the channels.

The plates built in this way with the grid-like channel arrangement 2 are suitable for receiving differently guided heat pipes 3, as shown in FIGS. 6b, 6c and 6d, it being possible to dispense with conventional center plates.

FIGS. 6b and 6c show different courses of the heat conduction pipes 3 on a bottom section shown in FIG. 6a and composed of three plates 100. FIG. 6b shows two groups of heat conduction pipes running parallel to one another, the loop ends of which 3.1 3.6 are each formed by an arch 2.5.1 2.5.6.

An oblique configuration of the heat pipes is shown in Fig.6 c. In view of the clarity of the drawing, connections and fittings have been omitted.

The advantage is that the entire surface of the channel arrangement - in plan view of the flat side of the plate - is less than half, in the present case about 45% of the total area of the plate and that the installed heat pipes 3 over almost their entire length from the material ^¬ al the plate are virtually surrounded. Thus, the ^{sound-¬-insulating} properties of the panel are improved because the cavities caused by the so-called drum effect is largely minimized.

Before the heat pipes are inserted, heat conducting sheet elements 50.1; 60 can be used in the channels. The heat-conducting sheets are provided with a centrally arranged straight or curved trough, to which lateral wings 30.1, 30.2 are connected in one piece. The heat-conducting sheets intended for bends can also serve with their troughs as a teaching for bending the heat-conducting tubes, so that the corresponding bend section can be bent with them.

6d shows a helical configuration of the pipe laying. As can be seen from the figure, several approximately diagonally arranged heat-conducting sheet elements 50.1 and four groups of differently cut heat-conducting sheet strands 60, each forming a triangle in plan view, are pressed into the laying plates. FIG. 7 shows a further embodiment of the plate (reference number 200), in which the arcs 2.5.1 2.5.n form a closed circle 25. The square plate 200 is otherwise similar to the rectangular plate 100.

8 shows a laying of the heat-conducting sheet strands 60 and the deflection plates 50.3. The individual deflection plate 50.3 is shown in detail in FIG. 9. This has an arc-shaped trough 35.3, which merges into two straight trough sections 71 ending at 32.1 and 32.2. An elongated support element 64 runs along a side edge 43.3 opposite the ends 32.1, 32.2, which is created by simply bending the flat body at an angle o = 45 ° and has a free edge 74. This angle size was chosen to be optimal because, firstly, it ensures sufficient hold on the plastic plate and secondly, the brittle material of the plastic plate is not torn.

In order to be able to fix the already laid deflection plate 50.3 to a laying plate 100 or 200, it is placed on the plate in such a way that the mounting element 64 with its free edge 74 deepens into the relatively soft material of the plate element, specifically within a channel , as can be seen in Figure 10.

Figures 11 and 12 show a special attachment of the heat pipe 55 in the trough of the deflection plate. There are four button-shaped beads on the trough, pointing towards the inside of the trough and reducing a trough cross section Q2 15.1 15.4 introduced, which are arranged on an outer trough edge 67. The beads 15.1 15.4 form a simple and inexpensive fastening or snap-in system for the heat pipe 55 to be installed. The beads 15.1 15.4 ensure that the heat pipe 55 is laid in a stable position within the arc-shaped trough, ie the heat pipe 55 can practically no longer come out of the trough "Jump out".

FIGS. 15 to 17 show a one-piece heat conducting sheet strand 60 which is manufactured in the form of a rectangular flat body made of galvanized steel sheet with the aid of a punching machine (not shown). The dimensions of the flat body are: total length L1: 1000 mm, total width B1: 120 mm, thickness D: 0.5 mm.

The flat body is provided with a central groove or trough 35.1 for receiving a heat conduction tube, which merges into two planar wing parts 30.1, 30.2 arranged in mirror image to one another. The trough has a semicircular cross section which tapers slightly in the direction of the wing parts, as can be seen from FIG. 16. In another embodiment (not shown), the trough cross section is semicircular.

Transversely running, pre-punched predetermined breaking lines 44.1 44.n are furthermore applied to the elongated flat body, which are at the same distance A = 100 mm from one another and divide the heat-conducting sheet strand into heat-conducting sheet elements of the same length. The division or cutting to length of the heat conducting sheet However, the strand is only made by bending the strand by hand along the respective predetermined breaking line.

The predetermined breaking lines 44.1 44. or pre-punched sections are each divided into two predetermined breaking lines sections 77.1, 77.2 by a recess 46.1 46.n, the length of which corresponds approximately to the width of the wing part. The recesses 46.1, 46.n are each designed as a slot 56 with rounded ends that runs through the trough, the length L2 of which slightly exceeds a width dimension B2 of the trough — in projection onto a flat side 68 of the flat body 1.

Furthermore, FIG. 17 shows a plurality of elongated beads 42.1 42.n arranged on the predetermined breaking lines 44.1 44.n and lying outside the trough, each of which runs parallel to the trough 35.1. The beads 42.1 42.n stiffening the heat-conducting sheet strand are also punched out in one working step.

Cutting the heat-conducting sheet strand 60 to length creates heat-conducting sheet elements which in the present case are each 100 mm long. Of course, other division of the heat conducting sheet strand 60 is also possible, as required. If the heat-conducting sheet element is not cut to length from a heat-conducting sheet strand, but prefabricated as a single stamped piece (cf. FIG. 14), the slot is not punched out. The ends of the trough are each provided with a groove 81.

13 shows a heat-conducting sheet metal element 50.2 with an arcuate trough 35.2, which is aligned with the straight line Trough 35.1 connects. The arc radius B _R is approximately 60 mm. Such a heat-conducting plate element 50.2 can serve to hold a straight or a heat-conducting pipe bent by 90 °.
