Description

Technical field

BACKGROUND OF THE INVENTION The invention relates to a knob plate for installing a conduit for heating or cooling devices integrated in a floor or wall with a plurality of knobs that protrude from a substantially plate-shaped base body and between which conduits are arranged.

BACKGROUND OF THE INVENTION

Such stud plates are known, for example, from DE 302 42 08. The studs are here evenly distributed over the entire plate-shaped base body. In the plan view, the studs have the shape of an isosceles triangle, the bases of these triangles of two adjacent studs facing each other. By this arrangement of the studs, passages are formed between the studs, in which passages can be arranged substantially parallel to or at 45 ° to the bases of the rectangular base body. The lines can then be inserted into the passages, whereby the lines can also be arched in order to form, for example, spirals or meander loops. For this purpose, they are designed in the form of flexible hoses.

For the installation of, for example, underfloor heating, the stud plates are laid on the floor and subsequently a flexible heating conduit is inserted into the passages on the stud plate. In order to finish the floor, screed is then applied to the stud plate and the heating conduit.

By arranging the knobs on the plate base body of the knob plate, it is possible to install the heating conduit or in a spiral or even meandering manner, but on the other hand some radii of curvature are introduced to the heating conduit by the arrangement of the knobs. This restricts the freedom of establishment when installing a heating line. This may result in the installation of a heating conduit with these knob plates not at all or only partially possible in spaces of unusual shapes.

A further problem with such stud plates is the high need for space for their transport and storage. Although the stud plates usually consist of very lightweight plastics, such as styrpor, on the other hand, they are bulky and need a correspondingly large transport and storage space.

SUMMARY OF THE INVENTION

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a top plate of the type described above so that it can be used flexibly while providing advantages in transportation and use.

The object according to the invention is solved by a stud plate of the above-mentioned kind, which is characterized in that the studs are arranged in groups spaced apart and thus creating free spaces whose dimensions between the groups correspond at least to the outer dimensions of the groups.

This solution is simple and has the advantage that the heating ducts with almost any radius of curvature can be installed by means of the free spaces created. It is also possible to carry out unusual lines of the heating lines in the passages between the knobs, which differ from the usual installation schemes of the heating lines. Thus, the heating lines are no longer held by the knobs over the entire knob plate, but only within the knob groups. Between the groups of knobs, the heating line lies in a freely selectable arrangement. At the same time, the free space allows to reduce the transport volume of the burner boards. Based on the selected dimensioning, it is possible to stack two knob plates on top of each other, the knobs of both adjacent plates being folded together. The groups of one of the stud plates are arranged between the groups of the other stud plate in the free spaces. This greatly reduces the stacking height.

In a further preferred embodiment of the invention, rib-like protrusions can be provided on the base body, which protrude less than the studs against the base body and can then be guided on the projections. By means of these projections, the heating conduit located between the knobs does not lie entirely on the base body, but only on the projections. This makes it easier for the screed to come under the heating line so that the screed heating line can be completely surrounded. By this complete embedding, it is possible to improve the heat transfer from the heating line to the screed and thus to improve the efficiency of the floor heating.

It is also preferred that the groups of knobs are spaced at regular intervals throughout the base body. By means of this regular arrangement, the stud plate can be used universally. It may also be advantageous for the free spaces to be distributed at regular intervals over the entire surface area of the base body. This regular arrangement improves the stackability of the ram plates. In principle, groups and free spaces may also have different dimensions and be irregularly distributed on the base body. However, it would then have to be ensured that the groups and the voids are dimensioned and arranged in such a way that it is possible to stack the nail plates on top of one another with the nails facing each other.

Advantageously, the knobs within the group are arranged such that they form longitudinally extending passages and transversely extending passages for accommodating the guides with respect to the directions of the main axes of the rectangular stud plate. The installation of the wiring is thereby simplified.

It has also been found to be advantageous if the studs of adjacent groups form passages between them which extend in the direction of the main axes of the base body. It is also possible to simplify the installation, especially of direct heating lines.

Furthermore, it is advantageous if the knobs of the adjacent groups form passages between them which extend obliquely, preferably inclined by 45 [deg.] Against the directions of the main axes of the base body. This measure also facilitates the installation of direct heating lines.

It is also preferred that each group has an even number of knobs. Then it is always possible to arrange the knobs in pairs so that the installation can be facilitated.

In another preferred embodiment of the invention, the protrusions may be designed as ribs. These ribs can then pass between adjacent groups. The function of the ribs and knobs can then be separated. As a result, the heating lines inside the knobs can be installed at a distance from the base body, and then lie on the ribs or on the base body only outside the groups of knobs.

For this, it has proved advantageous if the ribs form an angle of 60 [deg.] With the side edge of the rectangular base body. In this way, it is also possible to ensure that the heating lines on the base body or on the ribs are brought to rest on diagonally installed heating lines on the rectangular base plate.

It may further be advantageous if the ribs form a cross-grid pattern. It is also possible to ensure that the heating lines are supported on the fins.

The knob groups may preferably be framed by ribs. Also by this measure the functions of the knobs and ribs can be separated.

Preferably, the grid pattern is formed by ribs substantially diamond-shaped. With such a rhombic arrangement of the fins, it is possible to reliably reach the heating lines on the fins in the numerous arrangements of the heating lines.

The ribs may preferably cross in free spaces. It is also possible to improve the reliable positioning of the heating lines on the fins.

In a further preferred embodiment of the invention, the base body may have a peripheral edge that extends substantially from the base body at the same height as the ribs. In this way, it is also possible to ensure that the heating lines are brought to rest on the passages to the adjacent stud plates.

According to a further preferred embodiment of the invention, the studs may be substantially prismatic with five side surfaces having a front side surface on which the joining side surfaces adjoin on both sides, the two joining side surfaces being substantially parallel to each other, and the rear side sides then adjoining the rear side surfaces surfaces that are connected to each other. Such a five-surface design of the knob allows the individual installation of heating lines.

It may also be advantageous that the front sides and / or the connecting sides and / or the back sides of two adjacent studs have a greater distance at the end of the stud facing away from the base body than between this end and the base body. In this way it is possible to realize a substantially concave design of the side surfaces. By means of two opposing concave side surfaces, it is possible to create a recess for the heating conduit. These recesses can be selected such that the greatest distance of the side surfaces corresponds essentially to the diameter of the tubular heating ducts, and the distance at the upper end is chosen such that the elasticity of the material of the nipples or nipples is allowed. lines from a recess formed by knobs.

With the studs thus formed, it has proved to be advantageous if the rear side surfaces or the front side surfaces of the paired studs are facing each other. In this way, passages are easily formed.

Flexibility in the installation of heating lines can also be increased by the rear side surfaces at an angle of 90 °.

Furthermore, the flexibility in the installation of in particular straight lines can be increased when the rear side surfaces and / or the connecting side surfaces and / or the front side surfaces of adjacent pairs of studs are aligned.

In particular, the installation of straight lines can also be simplified when the rear side surfaces and / or the connecting surfaces and / or the front side surfaces of the knobs of adjacent groups are flush with one another.

In a further preferred embodiment of the invention, two different types of studs may be provided which differ in the formation of the front side surface, with a rib of the first type having a rib-like projection which overhangs the front side surface and a groove recess in the second type. snapped back against the front side. In this arrangement of the knobs, it is possible to improve the gripping of the heating lines between adjacent knobs by means of ribs. Thus, the front side surfaces of the adjacent studs form, on the one hand, a passage which guides the heating conduit and, on the other hand, a rib-like projection and a recess for the heating conduit.

In this case, it may be advantageous if groups are formed of at least one pair of knobs whose front side faces and one pair of knobs whose rear side faces are facing each other. In this way groups with at least four knobs are formed. Due to the arrangement of the knobs, the heating pipes can be installed in any pattern.

It has also been found to be advantageous if groups are formed from one pair of knobs whose front faces are facing each other and from one pair of knobs whose back faces are facing each other. This allows for a symmetrical design of the stud plates, facilitating the overview of the installation of the heating lines.

For this, it is advantageous if at least the studs are of an elastic material. It is thus possible to press the heating conduit between the knobs and with a certain bias.

If the stud plate is made of plastic, preferably styropore, it may have good insulating properties.

DETAILED DESCRIPTION OF THE INVENTION

The stud plate 1 is formed by a base body 1a with a plurality of studs 2. It consists of a thermally insulating, resilient and compressible material, for example foamed or extruded polystyrene.

The knobs 2 are concentrated in mutually separated groups 3, the groups 3 being evenly distributed over the entire surface 4 of the knob plate 1. Between the groups 3, free spaces 5 are formed. Also these free spaces 5 are arranged evenly distributed over the entire surface 4 of the knob plate 1. or its base body 1a. The distances between the groups 3 are chosen in such a way that they create free spaces with dimensions which are at least as large as the external dimensions of the groups.

The base body is substantially rectangular with side edges extending perpendicular to each other. At the side edges, the plate-like base body 1a has a raised edge 6, on which the insulated rows 7 of the knobs 2 are located. These groups are incomplete and can be refilled by assembling the individual knob plates.

In FIG. 1, the distances 8 between the groups 3 of the knobs 2 are entered. The dimensions of these distances are chosen so as to allow the installation of conventional mostly flexible heating lines, in particular for floor heating. The distance shown by way of example is 50 mm. However, larger distances, such as 200 mm between the groups in the vertical direction in the representation of FIG. 1 and 120 mm perpendicular to it. The dimensions of 120 x 200 mm for the free space correspond to the external dimensions of the stud group. This is shown in FIG. 1 clearly apparent.

The groups 3 have a paired arrangement of the studs 2. The studs form rows parallel to the sides of the stud plate 1. By this arrangement of studs, longitudinal and transverse passages 10 and 11 are formed between adjacent studs.

12th

As an example, FIG. 2 to illustrate, in the passages so formed, the insertions 9 of the straight guide. As is well understood, the conduit part 9 may be installed either parallel to or at an angle to the side edges of the stud plate. The obliquely extending guide portions 9 form an angle of 45 [deg.] With one of the two lateral edges of the stud plate 1. On the other hand, the group arrangement of the knobs does not allow arbitrary installation of the curved sections 9 of the conduit, as shown in FIG. Third

Another possibility of installing a part of the conduit is shown in FIG. 5, wherein the knob plate is installed on the wall

13. For this purpose, the stud plate must be appropriately cut in advance. Nevertheless, the arrangement of the knobs along such an inclined wall also allows the installation of a heating pipe close to the wall.

In the present exemplary embodiment, the individual groups 3 are formed by eight knobs 2. However, it is also possible to form groups of four knobs. It is also possible to create these groups from a plurality of knobs. The arrangement of the studs or groups of studs is preferably strictly symmetrical, even each group having the same number of studs.

The studs themselves have essentially the same basic form. In the present example, the studs 2 have an almost identical shape. They differ only in the central area of one of their sides.

The knobs 2 have a body 14 with a shape corresponding to a pin with straight sides, whereby the knobs have a champignon-like shape. More specifically, each knob 2 has a conically extended base 15 on which the knob extends from the base plate body and through which it is connected to the base body surface 4. The body 14 of each stud extends as a pin 16 and is concave on the sides. This gives the pin or stud a certain forming ability perpendicular to their longitudinal dimension.

Due to the conical design of the body 14 of each nipple 2, the end of the body 14 forms a part 17 that faces away from the base body, forming a peripheral edge as a retainer. The distance of the adjacent studs is selected such that it essentially corresponds to the outside diameter of the heating conduit. The distance in the region of the end 17 has a smaller dimension, which, on the one hand, allows the heating line to be held between the knobs and, on the other hand, it allows the heating line to be pressed between the knobs.

Basically, the stud plate has two types of studs. Both types have a substantially prismatic base form with front side faces VS, adjoining connecting side faces VB, which on both sides adjoin the front side faces, and rear side faces RS, which adjoin and are connected to each other. Thus, in the plan view of the surface 4 of the base body 1a, the studs 2 are pentagonal.

They are symmetrical along a line perpendicular to the front side surfaces and through the connecting section of the two rear side surfaces. The two connecting side surfaces VB run parallel to each other. All side surfaces, i.e. the front side surfaces VS, the joining side surfaces VB and the rear side surfaces RS are concave. Each of these flanks thus forms a depression 21.

It is necessary to distinguish two types of front side surfaces, namely the front flank 18 with pressure sides 22 with a ribbed collar 23 that extends in a vertical direction and the front flank 25 having a groove recess 26, thereby forming two prismatic collars 27 and 28 that extend towards the outside of the body of the stud. These collars form two support zones with a recess 26 that increase the pressure exerted by the rib 24 of the second stud on the leading edge when both sides 22 and 25 form passages 10.

The studs 2 form a straight and longitudinal passage therebetween when the front flanks 22 and 25 are arranged to form a shaft. The heating section 9 inserted by way of example is retained by the two front sides.

The basic arrangement within the same group of knobs is shown in FIG. 9, 10, 14 and 15. This is a group of eight knobs as will be explained in the following description. However, the groups may also have a smaller number of knobs, for example 4 or 6, or another even number of knobs, as desired.

According to a preferred embodiment, an even number of knobs is preferably used. Each pair has studs with different front sides 22 and 25. The studs are arranged side by side in one longitudinally extending line, either with their front side faces facing each other, or in the opposite arrangement, i. j. that their rear side surfaces are opposite. The pairs are arranged alternately on the transversally extending lines.

The studs located on the corners of the group 3 are bypassing studs 29, and in this case they are arranged so that their front sides face inwards of the group, or the guide studs 30, which in this case are arranged with their front side surface facing the outside of the group. The front side surfaces of both these types of studs, when arranged so as to form a shaft, not only form the conduit part 9 of the heating conduit 31, but in particular allow vertical fastening by clamping this part of the conduit.

As can be clearly seen from the drawings, not only the front flanks 22 and 25 and the front side faces VS of the individual studs, but also the rear side faces RS of adjacent stud pairs within the group, are aligned. They also fit the connecting side faces of VSBs of adjacent studs. To this end, the rear side surfaces RS and the front side surfaces VS of the studs of different groups are also flush.

In FIG. 4, the installation directions of the lines within the group are shown schematically in dashed lines.

The rib-like protrusions 32 extend between individual groups of studs. These rib-like studs 32 project from the base body, but substantially less than the studs themselves. The rib-like protrusions form a diamond pattern, with individual diamonds surrounding groups of knobs. These ribbed protrusions serve as a base for the heating conduit on the base body.

The function of the invention will now be described in more detail.

To install underfloor heating, a floorboard is first laid on the floor in a certain area. This is usually done at the stage of the building's rough construction. The floor is completely covered with studded boards. The stud plates lie on each other with their lateral edges. In accordance with the design of the space, the stud plates must still be properly trimmed, for example, as shown in FIG. 5th

After the floor is covered with the stud boards, a heating conduit 31 may be installed. Mostly they are flexible plastic conduits. Conventional heating lines may have different diameters, such as 12 mm, 14 nm, 16 mm, 18 mm and 20 mm, or intermediate dimensions, as well as dimensions coming from other unit assemblies. Due to the conical design of the side surfaces, it is then possible to install heating ducts of different diameters in the passages between the studs. During installation, the heating cables are pressed between the knobs, this being possible due to the elasticity of the knobs or the knob plates. The embossing can be effected, for example, with a foot to push the guide between the studs and to remain in the desired position.

The installation of the heating lines can be carried out in any path. It is possible to install a heating conduit either only between the front side surfaces of the studs, or between the connecting side surfaces of adjacent studs, or also between the rear side surfaces of adjacent studs. Since the rear side surfaces, the connecting side surfaces and the front side surfaces of the studs of the different stud groups are flush with each other, greater straight distances can also be bridged. At the same time, heating lines with almost any radii of curvature can be installed for free space. The various installation options are particularly clear from FIG. 2, 3, 4, 5, 6 and 7. FIG. 4 the installation directions are indicated by dashed lines.

Also in FIG. 16 and FIG. 17, examples of spatial installations can be seen. More boards are stacked side by side.

The various installation options are also shown in FIG. 12 to FIG. 15. FIG. 12 and FIG. 13 shows how heating ducts of different diameters can be installed in the burner plate. In FIG. 14 and FIG. 15 shows in dotted lines the directions in which the heating lines can be installed.

The possibility of arbitrary installation is based mainly on the free space between individual groups of knobs. Only this way it is possible to choose almost any installation direction for heating lines. This represents a different progress compared to conventional stud plates where a pattern is forced to be installed.

When the heating ducts are inserted into the passageways, they are supported perpendicularly to the surface of the base plate on the fins 32. This allows the heating lines to come into contact with the base plate body only in the region of the fins. Due to their rigidity, the heating lines are loose between the fins, which means that they are spaced apart from the base body. In alternative solutions, it is also conceivable to connect the pairs of knobs to each other by ribs. These ribs have the advantage that they completely surround the heating lines during the application of the screed. The screed is applied after the installation of the heating line as a step to finish the floor.

A further advantage of the invention resulting from the existence of free spaces relates to the shelf life and transport of the ram plates. FIG. 8, it is clear how the stud plates according to the invention can be stored. Because of the formation of the groups of studs and the free spaces arranged between them, it is possible to store the stud plates in such a way that the studs of the stacked stud plates are facing each other and the stud groups of one stud plate fit into the free spaces of the other stud plate. As a result, the stacked height is noticeably reduced.
