Description

The invention relates to a system with at least one clay building board.

Clay is generally known as a building material. The clay is applied directly to a wall structure on site and then dries on the wall.

The disadvantage of this is that no prefabrication is possible.

It is therefore an object of the invention to create a system which can be prefabricated and/or assembled in a simple manner.

The solution to this task is carried out through the system of independent claims.

According to the invention, the system has at least one clay building board.

The clay building board can also simply be referred to as a clay board.

The clay building board has, preferably dried and/or fired, clay and, preferably dried and/or fired, clay.

The clay building board preferably has or consists of dried, unfired clay and dried, unfired clay. Fired components are preferably not provided.

Loam and clay, especially in combination with each other, have good moisture and/or heat properties and, for example, give off heat over a long period of time. The system according to the invention can therefore also serve as a heat storage device, for example in conjunction with a heat pump.

For example, the clay building board can be referred to as a building board. The term clay building board was chosen purely for the sake of simplicity, although the clay building board has at least clay in addition to clay. The proportion, e.g. the % by weight, of clay is preferably equal to, larger or smaller than the proportion of clay.

The proportion of clay to clay is preferably at least or exactly 2:1, 3:1, 4:1 or 5:1.

Preferably, the clay building board can have at least one additive, e.g. sawdust, hemp shives and/or other natural materials.

The clay building board has a first component of a tongue-and-groove connection on at least one end face. The first component of the tongue and groove connection is preferably a groove or a tongue.

The first component of the tongue and groove connection preferably extends over the entire length of the end face.

For example, the clay building board can be rectangular. If the clay building board is not square, the first component of the tongue and groove connection is preferably provided on a long or short end face of the clay building board.

The length and/or width of the clay building panel can be between 20 cm and 40 cm, for example 24 cm or 36 cm. With larger dimensions, there is a risk that the clay building panels will warp in a drying chamber.

The depth, i.e. the thickness, of the clay building board can be between 3 cm and 6 cm, e.g. 4.5 cm.

On one flat side, the clay building board has channels open to the outside for heating cables.

The heating cables can be used for heating and/or cooling.

With heating cables inserted, the clay building board can form surface heating or surface cooling.

For example, at least or exactly two, three, four, five, six, seven, eight, nine or ten channels can be provided.

The channels are preferably oriented parallel to one another and/or in the longitudinal or transverse direction of the clay building board.

If the clay building board is used as a floor element, the channels are open at the top, for example. However, if the clay building board is used as a wall element, the channels are open to the side.

The channels can be round or square, for example.

Preferably, the channels each have at least one undercut. The channels can be V-shaped or cup-shaped, for example. This prevents the heating cables from coming loose unintentionally.

The heating cables can be an optional part of the system.

For example, the heating cables can be an aluminum composite pipe. The diameter can be, for example, 14 mm or 16 mm.

Because the clay building board has channels for heating cables, the different trades can be separated from each other during assembly, which simplifies the coordination of the craftsmen. This means that the clay building panels can first be installed without the need for a heating engineer. This preferably only lays the heating cables after the clay building panels have been installed.

Inside, the clay building board has at least or exactly one passage for weight reduction.

The bushing is preferably completely enclosed on the circumference, i.e. the bushing is not open to the outside at the side. However, this is preferably open at the end areas, i.e. at the front and/or back.

The earth building panels can be easily transported and/or assembled due to the implementation. For example, these can also be used as wall elements. Without this this would not be possible and would require a lot of effort on the part of the fitter.

The implementation simplifies and/or reduces prefabrication. This way, material can be saved.

Preferably, the bushing completely penetrates the clay building board.

The implementation is preferably oriented in the longitudinal or transverse direction of the clay building panel.

For example, the feedthrough can be oriented parallel to the channels.

The system has at least one bearing bar.

The storage slat is used to store the clay building board. This means the clay building board can be attached easily.

For example, the bearing slat can comprise or consist of a wooden material, e.g. spruce wood.

Preferably, the support bar can be between 2 m and 3 m, e.g. 2.5 m, long. The width can be, for example, between 5 cm and 8 cm, e.g. 6.5 cm. The depth, i.e. the thickness, can be between 3 cm and 6 cm, for example 4.5 cm.

The bearing bar has a second component of the tongue-and-groove connection on at least one end face. The second component of the tongue-and-groove connection is preferably a tongue or a groove.

The second component of the tongue-and-groove connection preferably forms a counterpart to the first component of the tongue-and-groove connection. If a groove is provided on the clay building board, the support bar has a tongue and vice versa.

The second component of the tongue and groove connection preferably extends over the entire length of the, preferably long, end face.

Preferably, several clay building panels and several bearing slats are provided.

The invention therefore also relates to an arrangement with several clay building panels and several bearing slats.

Preferably, clay building panels and storage slats alternate. A clay building panel is always arranged between two support slats.

For example, the bearing slats can be mounted on a wall. The clay building panel can then be inserted from above and is held laterally by the two bearing slats. This makes it easy to safely install prefabricated clay building panels.

Further developments of the invention can also be found in the dependent claims, the description and the accompanying drawings.

According to one embodiment, the clay building board has a first component of a tongue-and-groove connection on two opposite end faces.

The clay building board can therefore be easily stored on two sides on a support slat. This allows for a secure hold.

According to a further embodiment, one of the end faces has a groove and the opposite end face has a tongue.

The first components of the tongue-and-groove connections on the various end faces therefore differ.

This is advantageous because adjacent clay building panels can be connected to one another directly, i.e. without an intermediate support lath. This can be advantageous, for example, with fired clay building panels.

According to a further embodiment, both end faces have a groove or both end faces have a tongue.

The first components of the tongue-and-groove connections on the various end faces are constructed the same.

The clay building board is preferably designed to be axially symmetrical.

This allows production to be simplified.

According to a further embodiment, the bearing bar has a second component of a tongue-and-groove connection on two opposite end faces.

The support slat can therefore be easily connected to a clay building board on two sides and stored there.

For example, one of the end faces can have a tongue and the opposite end face can have a groove.

The second components of the tongue-and-groove connections on the various end faces therefore differ.

Alternatively, both end faces can have a tongue or both end faces can have a groove.

The second components of the tongue-and-groove connections on the different end faces are constructed the same.

In this case, the bearing bar is preferably designed to be axially symmetrical.

This allows production to be simplified.

The design of the bearing slat can preferably be adapted to the design of the clay building panels so that the tongue and groove connections engage with one another and can thus be connected.

According to a further embodiment, the clay building board has grooves on at least one flat side as a plaster adhesion area.

The grooves are preferably arranged on the same flat side as the open channels. However, the grooves are preferably less deep.

It is also conceivable that grooves are provided on both flat sides.

The grooves are preferably oriented parallel to one another and/or in the longitudinal direction of the clay building board.

The grooves preferably extend over the entire length and/or width of the flat side.

According to a further embodiment, the clay building board has at least or exactly one, two, three, four, five, six, seven, eight, nine, ten, eleven or twelve bushings on the inside.

The more penetrations there are, the lighter the clay building panel is.

For example, adjacent bushings can be arranged equidistantly or in pairs equidistantly in the clay building panel.

All feedthroughs are preferably arranged in one plane and/or oriented parallel to one another.

Preferably, one feedthrough or two feedthroughs can be provided between two adjacent channels.

The form of the bushings is basically arbitrary. For example, the cross-sectional area can be round, oval, angular, for example rectangular or triangular.

The bushings are preferably designed to be identical in construction. Alternatively, these can be shaped differently.

According to a further embodiment, the clay building board is produced using the extrusion process.

This enables simple and cost-effective prefabrication of the clay building panel.

The invention relates to the use of the system according to the invention as a wall element.

The lightweight design makes it easy to mount on the wall. The bearing slats can be used to screw the system to a wall structure.

If heating cables are inserted into the ducts, wall heating is easily achieved.

The invention further relates to the use of the system according to the invention as a floor element.

Depending on your needs, the system can be used as a wall element or floor element.

The bearing slats can be used to screw the system to a floor substructure and/or a floor covering to the system underneath.

In principle, it is also possible to use the system according to the invention as a ceiling element.

The system can therefore be used in a variety of ways.

Finally, the invention relates to a method for assembling a system according to the invention, in which the earth building board is connected to a bearing bar via tongue-and-groove connections on opposite end faces.

The system is screwed to the bearing slats with a holding structure or floor covering, for example at an angle of 45°.

For example, the bearing slats can first be mounted on a wall. The clay building panel can then be inserted from above.

When installing on the floor, the bearing slats do not need to be pre-assembled. This means that a support slat and a clay building board can be laid alternately on the floor.

Regardless of whether the system is mounted on the wall or on the floor, clay building panels and support slats alternate. A clay building panel is always stored between two support slats.

The clay building board is preferably only attached indirectly via the support slats. For example, the clay building board itself is free of drilling and/or screw holes.

Once the system is installed, heating cables can, for example, be laid in the open channels.

The system can then be plastered, for example, or a base plate, for example made of wood, can be placed on top and screwed on if necessary.

All embodiments and components of the device described here are preferably designed to be assembled using the method described here. Furthermore, all embodiments of the device described here and all embodiments of the method described here can each be combined with one another, preferably also independently of the specific embodiment in the context of which they are mentioned.

1 shows a system with a clay building board 10 and a support bar 12.

The clay building board 10 has a first component 14 of a tongue-and-groove connection 16 on two opposite end faces.

The first component 14 is designed as a spring 18 on one end face. On the other end, however, the first component 14 is designed as a groove 20.

The clay building board 10 has channels 22 for heating cables 24 that are open to the outside on the upper flat side. These are in 1 cup-shaped, but can basically be of any shape.

Furthermore, grooves can optionally be provided on the upper flat side as a plaster adhesion area, which are not shown.

Inside, the clay building board has 10 bushings 26 to reduce weight. These are in 1 round, but can basically be of any shape.

The bushings 26 are preferably arranged between the channels 22.

The bearing bar 12 has a second component 28 of the tongue-and-groove connection 16 on two opposite end faces.

The second component 28 is designed as a groove 20 on one end face. On the other end, however, the second component 28 is designed as a spring 18.

The spring 18 of the clay building board 10 can be inserted into the groove 20 of the bearing bar 12.

In the system that in 2 is shown, the bushings 26 are each arranged in pairs.

Two feedthroughs 26 are preferably arranged between the channels 22.

In 3 an arrangement of several systems is shown. Bearing slats 12 and clay building panels 10 alternate here.

In the case of a floor structure, a fill 30 can be provided as the subsurface. For example, CEMWOOD®, expanded clay, Naturefloor, lime chippings or the like can be used as a load-bearing fill.

At least one compensating plate or insulation 32 can be attached to the fill. These can be, for example, pressed straw panels and/or soft fiber panels, e.g. made of wood, or similar materials.

The clay building panels 10 and bearing slats 12 are laid on this insulation 32.

As an upper end - after the heating cables 24 have been inserted into the channels 22 - a floor covering 34 designed, for example, as a plank or solid floor can be laid.

The solid floor 34 can be screwed to the bearing slats 12, for example.

A solid floor 34 can therefore be laid on underfloor heating without adhesive.

4 shows a top view of several systems according to the invention. The bearing slats 12 are preferably longer than the earth building panels 10. A bearing slat 12 can thus be used for a large number of earth building panels 10.

There are various ways to fill the channels 22 with heating cables 24. In the in 4 In the variant shown, only two heating cables 24 are provided per clay building board 10.

In the variant which in 5 is shown, each clay building board 10 has three heating lines 24.

In the in 6 In the variant shown, each clay building board 10 has five heating cables 24.

The heating lines 24 are preferably connected to one another or designed as a common heating system. In this case, the term heating cable describes a, preferably straight, section of the heating system.

The heating lines 24 are preferably oriented parallel to one another.

In 7 A floor structure is shown, which is shown partially transparent for better visibility.

A fill 30 is followed by a compensating plate or insulation 32.

Above this are the clay building panels 10, the bearing slats 12 and the heating cables 24.

The upper end is formed by a plank or solid floor 34.

8th shows a wall structure that is partially transparent for better visibility.

Horizontal slats 36 form a holding structure on a wall to be insulated. Preferably, several slats 36 can be arranged parallel to one another, for example at a distance of 60 cm or 80 cm.

For example, diffusion-open materials 38, e.g. stuffing hemp, can be provided between the slats 36. These can, for example, push the clay building panels 10 slightly forward.

The entire system is preferably open to diffusion.

The clay building panels 10, the bearing slats 12 and the heating cables 24 are arranged in front of it. For example, a spacer, for example made of wood, preferably spruce, can be provided at the very bottom. The spacer can be designed, for example, as a three-layer plate. Preferably the thickness is only 2/3 in order to create space for the arcuate connecting piece of the heating cables 24. The connecting piece can, for example, be installed without denomination. For example, it can be a 500 Ifm aluminum composite pipe. Due to the overlap of the heating lines 24, a notch can be provided. For example, the lowest heating cable 24 can be bent backwards.

An area can also remain free at the top. The curved connecting pieces of the heating conductors 24 therefore have enough space available. The connecting piece can, for example, be installed without denomination. For example, it can be a 500 Ifm aluminum composite pipe.

For example, solid wood floorboards 40 can be installed in front of it. These can be screwed to the bearing slats 12, for example.

As in 9 is shown, instead of solid wood floorboards 40, lightweight clay building boards 42, hemp building boards, gypsum fiber boards, e.g. Fermacell®, gypsum plasterboards, plasterboards, lime carrier boards, gasket carrier boards or other plaster carrier boards can be provided. These panels 42 can optionally be plastered, for example with clay plaster 44 or lime plaster.

Furthermore, it is conceivable to plaster the clay building panels 10 directly.

Since the slat spacing of the bearing slats 12 in all variants and embodiments preferably corresponds to the construction grid dimension, e.g. 125 cm with two dividing slats in the gap, the components, which can also come from common manufacturers, for example, can be screwed together in a simple manner.

A vapor barrier and/or vapor barrier can optionally be provided.

Overall, the structure is comparatively narrow. For example, the system is suitable for the subsequent installation of interior wall insulation, underfloor heating and/or wall heating, e.g. in public and/or listed buildings.
