Definitions
- the invention relates to a brick comprising an essentially cuboid body which has a longitudinal connecting groove on a first side with a cross-section which is at least partially enlarged towards the inside.
- bricks of the type mentioned which have a groove for connection to another brick.
- the groove has an inwardly at least partially enlarged cross-section, as a result of which a positive connection with a corresponding tongue or pin can be formed.
- the brick can, for example, have a groove on one side and a tenon on the other side, so that adjacent bricks can be connected to one another by inserting the tenon of one brick into the groove of another brick.
- a particular disadvantage of these solutions is that only a row of bricks is connected to one another. This creates gaps in the connections, so that the wall is not tight and an unwanted exchange of air can take place between the outside and inside, reducing the insulation of the wall.
- a transverse connection groove running essentially parallel to the longitudinal connection groove is provided with an inwardly at least partially enlarged cross section in a second side adjacent to the first side.
- at least two grooves are provided, which are provided on two different sides of the brick. The sides are adjacent, that is, they have a common (possibly imaginary) edge. The two sides (surfaces) are preferably essentially perpendicular to one another.
- a brick according to the invention is essentially cuboid and therefore basically has six sides.
- the sides can each be flat or have grooves and other elevations or depressions.
- the longitudinal connecting grooves and the transverse connecting grooves run continuously and each have a transverse opening (“groove opening”) running along the groove and a longitudinal opening arranged on the upper and lower side of the brick.
- a connecting element e.g is created across the course of the groove.
- the brick consists of solid wood, preferably spruce wood.
- the brick is made from a single piece of wood, into which the longitudinal connection groove(s) or the transverse connection groove(s) are preferably milled.
- connections between individual pieces of wood e.g. using screws or adhesive, especially glue.
- the brick is open to diffusion, so that no vapor barrier is required. It is preferably provided that the brick consists of untreated wood.
- the brick is preferably solid, that is to say without continuous cavities, for example bores, formed in the brick between two opposite sides. No additional insulating material is required here.
- the brick can preferably have openings, in particular continuous bores, for example for electrical lines.
- the longitudinal connection groove and the transverse connection groove extend essentially perpendicularly to an underside and/or an upper side of the brick.
- This arrangement enables one brick to be longitudinally joined to two other bricks, one of the further bricks being joined to the brick on the first side and the other of the further bricks being joined to the brick on the third side.
- a further transverse connection groove is provided in the fourth side opposite the second side, with the two longitudinal connection grooves preferably lying essentially opposite one another.
- a multi-shell wall by connecting the brick on the second side to a first further brick and on the fourth side to a second further brick.
- a multi-shell wall can be constructed in a simple manner using bricks arranged in a staggered manner.
- the presence of at least two cross-connecting grooves enables the connection of a brick with two bricks arranged next to it in a further layer, so that a solid, stable wall that is as impermeable as possible to the weather can be formed.
- two or more longitudinal connecting grooves are provided in the first and/or the third side.
- This design increases the flexibility of the bricks, for example by allowing a larger brick to be connected to two smaller bricks.
- a first, smaller brick is connected to a first longitudinal connection groove and a second, smaller brick is connected to a second longitudinal connection groove.
- first side and the third side as well as the second side and the fourth side are each arranged essentially parallel to one another.
- the cross section of the longitudinal connection groove and/or the transverse connection groove widens continuously away from the groove opening. Provision is particularly preferably made for the longitudinal connection groove and/or the transverse connection groove to be designed as a dovetail groove.
- a groove shape has the advantage that a connecting element arranged in the groove and corresponding to the groove shape, for example a wooden dowel, is held firmly in the groove with a positive fit. Furthermore, there is only one place for the connecting element, which means that when the connecting element is inserted, the bricks to be connected can be brought into the correct position relative to one another without any further action.
- a fold is arranged in at least one edge region.
- the brick here has a Stage in at least one, preferably two opposite edge areas.
- the step is formed by two boundaries, which are preferably substantially perpendicular to each other. If two folds are provided, they are preferably essentially parallel to one another.
- the fold is arranged between two sides of the essentially cuboid brick, preferably the upper side and another side, for example the second and/or fourth side. This fold can be used to form a form-fitting connection in the transverse direction to the fold line with another brick.
- the brick has a fold on an upper side in two opposite edge regions and a tenon on the underside in each of these two opposite edge regions.
- the tenons are designed in such a way that they can engage in the rabbets of another brick that has the same rabbet-tenon combination.
- the bottom of a first brick can engage in the top of a similar second brick and be connected as a result.
- the height of the pegs and the depth of the folds are preferably essentially the same size, so that stones of the same type lying on top of one another end flush.
- the height of the pegs is greater than the depth of the folds, as a result of which a cavity is created between the bricks lying one on top of the other, in which space, for example, air is arranged. Such a cavity increases the insulating effect of the wall formed by the bricks.
- the fold or folds is or are preferably arranged in such a way that the longitudinal opening of a transverse connection groove or a longitudinal connection groove, preferably completely, in Fold is arranged.
- the groove openings of the transverse connection groove(s) or the longitudinal connection groove(s) open into the corresponding fold and are arranged directly on the outside of the brick, so that a simple connection to another brick, for example using a connecting dowel, is possible.
- the longitudinal opening preferably extends in an area parallel to the surface of the brick.
- the depth of the transverse connection groove or of the longitudinal connection groove preferably corresponds essentially to the extent of the fold in the depth direction of the groove.
- a connecting dowel arranged in the groove and protruding beyond it lies against the delimitation of the fold perpendicular to the depth direction of the groove, so that the connection between the groove and the connecting dowel is stabilized.
- a further fold is preferably arranged in an edge region of the brick which runs transversely to the other fold. If three edge areas of the brick have a fold, a U-shape is formed by the folds when viewed from above.
- the brick preferably has a groove at the top, which runs perpendicularly to the longitudinal connection groove and the transverse connection groove.
- the groove particularly preferably runs essentially parallel to a fold arranged on the upper side of the brick.
- the groove is preferably designed to be continuous.
- a second brick arranged transversely to a first brick can be arranged in this groove in order to establish a connection.
- the longitudinal connection groove and/or the transverse connection groove preferably has a chamfer on the longitudinal opening in order to make it easier to insert a connection element, for example a wooden dowel.
- the longitudinal connecting groove and/or the transverse connecting groove preferably have a cross section that is essentially constant over the length of the groove in order to enable or facilitate the insertion of a wooden dowel or a tongue.
- At least one side of the brick has a weather profile that includes, in cross-section, a plurality of protrusions that serve to better drain water.
- the brick also preferably has a further, preferably continuous, groove on its underside. When connected to other bricks, this groove serves as an air volume, which further improves the wall's insulation.
- the grooves in particular the transverse connection groove(s) and the longitudinal connection groove(s), and possibly the fold and other grooves are preferably produced by milling.
- the invention further relates to a set comprising at least one brick according to the invention and at least one connecting dowel which is designed to be able to positively engage in the longitudinal connecting groove and/or the transverse connecting groove.
- the connecting dowel can therefore only be pulled out of the groove through a longitudinal opening in order to release the connection. Since it is difficult to simply pull it out in many cases because the connecting dowel is firmly connected to the brick, it is often easier to split the connecting dowel, for example with an axe, in order to loosen the connection between the dowel and the brick.
- the connecting dowel is designed to be able to engage in the longitudinal connecting groove and/or the transverse connecting groove of a first brick and at the same time to be able to engage in the longitudinal connecting groove and/or the transverse connecting groove of a second brick, whereby the first and the second brick are connected to one another can be connected.
- the connecting dowel can be used here to connect two bricks to one another by the connecting dowel engaging in a form-fitting manner both in a first groove of a first brick and in a second groove of a second brick.
- the cross section of the at least one connecting dowel essentially corresponds to the cross section of the longitudinal connecting groove and/or the transverse connecting groove.
- the connecting dowel(s) preferably has/have at least a length which corresponds to the height of the brick.
- the length of the connecting dowel is particularly preferably greater than the height of the brick, so that bricks arranged one above the other can also be easily connected to one another using a connecting dowel.
- the length of the connecting dowel preferably corresponds to at least 1.5 times, particularly preferably at least 2 times, in particular at least 2.5 times the length of the longitudinal or transverse connecting groove of a brick. This enables a stable connection between the bricks.
- the brick is made of spruce wood and the connecting dowel is made of beech wood. This combination results in a particularly good connection between the brick and the connecting dowel.
- the brick and the connecting dowel are made of the same type of wood.
- the connecting dowel is designed in such a way that the first brick and the second brick touch each other in the connected state.
- the connecting dowel is designed, for example, in such a way that the areas that can be inserted into the grooves, in particular longitudinal or transverse connecting grooves, are directly adjacent to one another.
- the connecting dowel has two dovetails directly adjoining one another in cross section.
- the connecting dowel has grooves (is corrugated) in the longitudinal direction, as a result of which any adhesive used for the connection, for example glue, better adheres to the dowel.
- the connecting dowel preferably has a chamfer, which facilitates the insertion of the connecting dowel into the corresponding groove in the brick.
- the invention further relates to a wall constructed from a set according to the invention, in which connecting dowels are arranged in longitudinal or transverse connecting grooves of at least one brick. It is preferably provided here that the connecting dowels are fastened in the longitudinal or transverse connecting grooves with the aid of wood glue, in particular casein glue.
- a wall with two, three or more shells is preferably provided, in which the individual shells are connected to one another by means of the transverse connecting grooves.

Description
Die Erfindung betrifft einen Mauerstein, umfassend einen im Wesentlichen quaderförmigen Körper, welcher in einer ersten Seite eine Längsverbindungsnut mit einem sich nach innen zumindest teilweise vergrößerten Querschnitt aufweist.The invention relates to a brick comprising an essentially cuboid body which has a longitudinal connecting groove on a first side with a cross-section which is at least partially enlarged towards the inside.
Aus dem Stand der Technik sind verschiedene Holzziegel zum Aufbau von Wänden für Häuser und andere Gebäude bekannt, die unterschiedliche Formen und Verbindungsmöglichkeiten aufweisen. Insbesondere aufgrund der erstarkenden Umweltschutzbewegungen wird Holz als nachwachsender Rohstoff wieder stärker nachgefragt und auch als Ersatz für bereits bekannte Lösungen, bspw. Tonziegel, verwendet. Um die einzelnen Holzziegel zu verbinden, werden im Stand der Technik bspw. Nägel, Schrauben oder Dübel genutzt. Weiters sind Holzziegel bekannt, die eine spezielle Form aufweisen und miteinander im Mauerverbund fest verbunden werden können.Various wooden bricks for building walls for houses and other buildings are known from the prior art, which have different shapes and connection options. In particular due to the growing environmental protection movements, wood is in greater demand again as a renewable raw material and is also used as a substitute for already known solutions, such as clay bricks. In order to connect the individual wooden bricks, nails, screws or dowels, for example, are used in the prior art. Furthermore, wooden bricks are known which have a special shape and can be firmly connected to one another in the wall composite.
Darüber hinaus sind Mauersteine der eingangs genannten Art bekannt, die eine Nut zur Verbindung mit einem anderen Mauerstein aufweisen. In einigen Fällen weist die Nut einen sich nach innen zumindest teilweise vergrößerten Querschnitt auf, wodurch eine formschlüssige Verbindung mit einer entsprechenden Feder oder einem Zapfen gebildet werden kann. Der Mauerstein kann bspw. auf der einen Seite eine Nut und auf der anderen Seite einen Zapfen aufweisen, sodass nebeneinanderliegende Mauersteine durch ein Einführen des Zapfens eines Mauersteines in die Nut eines anderen Mauersteines miteinander verbunden werden können. Nachteilig bei diesen Lösungen ist insbesondere, dass lediglich eine Reihe von Mauersteinen miteinander verbunden wird. Dadurch entstehen bei den Verbindungen Lücken, sodass die Mauer nicht dicht ist und ein ungewollter Luftaustausch zwischen der Außen- und der Innenseite stattfinden kann, wodurch die Dämmung der Mauer reduziert wird.In addition, bricks of the type mentioned are known which have a groove for connection to another brick. In some cases, the groove has an inwardly at least partially enlarged cross-section, as a result of which a positive connection with a corresponding tongue or pin can be formed. The brick can, for example, have a groove on one side and a tenon on the other side, so that adjacent bricks can be connected to one another by inserting the tenon of one brick into the groove of another brick. A particular disadvantage of these solutions is that only a row of bricks is connected to one another. This creates gaps in the connections, so that the wall is not tight and an unwanted exchange of air can take place between the outside and inside, reducing the insulation of the wall.
Es ist daher eine Aufgabe der Erfindung, einen Mauerstein der eingangs genannten Art bereitzustellen, der einen Maueraufbau ermöglicht, der eine verbesserte Dämmwirkung aufweist.It is therefore an object of the invention to provide a brick of the type mentioned at the outset which enables a wall structure which has an improved insulating effect.
Erfindungsgemäß ist bei einem Mauerstein der eingangs genannten Art vorgesehen, dass eine zur Längsverbindungsnut im Wesentlichen parallel verlaufende Querverbindungsnut mit einem sich nach innen zumindest teilweise vergrößerten Querschnitt in einer, zur ersten Seite benachbarten, zweiten Seite vorgesehen ist. Bei einem erfindungsgemäßen Mauerstein sind also zumindest zwei Nuten vorgesehen, die an zwei unterschiedlichen Seiten des Mauersteins vorgesehen sind. Die Seiten sind benachbart, das heißt, sie weisen eine gemeinsame (ggf. gedachte) Kante auf. Die beiden Seiten(flächen) stehen bevorzugt im Wesentlichen senkrecht zueinander.According to the invention, in a brick of the type mentioned at the outset, a transverse connection groove running essentially parallel to the longitudinal connection groove is provided with an inwardly at least partially enlarged cross section in a second side adjacent to the first side. In a brick according to the invention, at least two grooves are provided, which are provided on two different sides of the brick. The sides are adjacent, that is, they have a common (possibly imaginary) edge. The two sides (surfaces) are preferably essentially perpendicular to one another.
Ein erfindungsgemäßer Mauerstein ist im Wesentlichen quaderförmig und weist daher grundsätzlich sechs Seiten auf. Die Seiten können jeweils flach sein oder Nuten und sonstige Erhebungen bzw. Versenkungen aufweisen.A brick according to the invention is essentially cuboid and therefore basically has six sides. The sides can each be flat or have grooves and other elevations or depressions.
Die Längsverbindungsnuten und die Querverbindungsnuten verlaufen durchgehend und weisen jeweils eine längs der Nut verlaufende Queröffnung ("Nutöffnung") sowie eine an der Ober- bzw. Unterseite des Mauersteins angeordnete Längsöffnung auf. Ein Verbindungselement, bspw. ein Holzdübel, kann durch die Längsöffnung in die Nut eingeführt werden, sodass eine formschlüssige Verbindung quer zum Nutverlauf geschaffen wird.The longitudinal connecting grooves and the transverse connecting grooves run continuously and each have a transverse opening ("groove opening") running along the groove and a longitudinal opening arranged on the upper and lower side of the brick. A connecting element, e.g is created across the course of the groove.
Bevorzugt ist vorgesehen, dass der Mauerstein aus Vollholz, bevorzugt Fichtenholz, besteht. Hierbei ist der Mauerstein aus einem einzigen Stück Holz hergestellt, in welches die Längsverbindungsnut(en) bzw. die Querverbindungsnut(en) bevorzugt gefräst sind. Dadurch sind keine Verbindungen zwischen einzelnen Holzstücken, bspw. mithilfe von Schrauben oder Klebstoff, insbesondere Leim, nötig. Weiters entstehen bei einem derart hergestellten Mauerstein auch keine Fugen zwischen einzelnen Holzstücken, wodurch die Dichtheit des Mauersteines und der daraus gebauten Mauer verbessert wird. Der Mauerstein ist hierbei diffusionsoffen, sodass keine Dampfsperre benötigt wird. Bevorzugt ist vorgesehen, dass der Mauerstein aus unbehandeltem Holz besteht.It is preferably provided that the brick consists of solid wood, preferably spruce wood. In this case, the brick is made from a single piece of wood, into which the longitudinal connection groove(s) or the transverse connection groove(s) are preferably milled. As a result, there is no need for connections between individual pieces of wood, e.g. using screws or adhesive, especially glue. Furthermore, with a brick made in this way, there are no gaps between individual pieces of wood, which improves the tightness of the brick and the wall built from it. The brick is open to diffusion, so that no vapor barrier is required. It is preferably provided that the brick consists of untreated wood.
Der Mauerstein ist bevorzugt massiv, also ohne zwischen zwei gegenüberliegenden Seiten durchgehende Hohlräume, bspw. Bohrungen, im Mauerstein ausgebildet. Hierbei wird kein zusätzlicher Dämmstoff benötigt. Alternativ kann der Mauerstein bevorzugt Öffnungen, insbesondere durchgehende Bohrungen, bspw. für elektrische Leitungen, aufweisen.The brick is preferably solid, that is to say without continuous cavities, for example bores, formed in the brick between two opposite sides. No additional insulating material is required here. Alternatively, the brick can preferably have openings, in particular continuous bores, for example for electrical lines.
Weiters ist bevorzugt vorgesehen, dass die Längsverbindungsnut und die Querverbindungsnut sich im Wesentlichen senkrecht zu einer Unterseite und/oder Oberseite des Mauersteins erstrecken. Bei dieser Ausbildung wird es ermöglicht, mehrere Mauersteine übereinander zu schichten, wobei die Längs- bzw. Querverbindungsnuten mehrerer Mauersteine so angeordnet sind, dass hierdurch eine oder mehrere durchgehende Nuten gebildet werden, die zur Verbindung bzw. Stabilisierung der Mauer genutzt werden können.Furthermore, it is preferably provided that the longitudinal connection groove and the transverse connection groove extend essentially perpendicularly to an underside and/or an upper side of the brick. This design makes it possible to stack several bricks one on top of the other, with the longitudinal or transverse connecting grooves of several bricks being arranged in such a way that one or more continuous grooves are formed as a result, which are used to connect or stabilize the wall be able.
Bevorzugt ist vorgesehen, dass in der der ersten Seite gegenüberliegenden dritten Seite eine weitere Längsverbindungsnut vorgesehen ist, wobei die beiden Längsverbindungsnuten einander bevorzugt im Wesentlichen gegenüberliegen. Diese Anordnung ermöglicht die Verbindung eines Mauersteins mit zwei weiteren Mauersteinen in Längsrichtung, wobei einer der weiteren Mauersteine auf der ersten Seite mit dem Mauerstein verbunden ist und der andere der weiteren Mauersteine auf der dritten Seite mit dem Mauerstein verbunden ist.Provision is preferably made for a further longitudinal connection groove to be provided in the third side opposite the first side, with the two longitudinal connection grooves preferably lying essentially opposite one another. This arrangement enables one brick to be longitudinally joined to two other bricks, one of the further bricks being joined to the brick on the first side and the other of the further bricks being joined to the brick on the third side.
Weiters ist bevorzugt vorgesehen, dass in der der zweiten Seite gegenüberliegenden vierten Seite eine weitere Querverbindungsnut vorgesehen ist, wobei die beiden Längsverbindungsnuten einander bevorzugt im Wesentlichen gegenüberliegen. Hierbei ist es möglich, eine mehrschalige Wand bereitzustellen, indem der Mauerstein auf der zweiten Seite mit einem ersten weiteren Mauerstein verbunden wird und auf der vierten Seite mit einem zweiten weiteren Mauerstein verbunden wird.Furthermore, it is preferably provided that a further transverse connection groove is provided in the fourth side opposite the second side, with the two longitudinal connection grooves preferably lying essentially opposite one another. Here it is possible to provide a multi-shell wall by connecting the brick on the second side to a first further brick and on the fourth side to a second further brick.
Bevorzugt ist vorgesehen, dass in der zweiten und/oder der vierten Seite zwei oder mehr Querverbindungsnuten vorgesehen sind. Bei dieser Anordnung kann auf einfache Art und Weise eine mehrschalige Wand mithilfe von versetzt angeordneten Mauersteinen aufgebaut werden kann. Durch das Vorhandensein von zumindest zwei Querverbindungsnuten wird die Verbindung eines Mauersteins mit zwei in einer weiteren Schicht daneben angeordneten Mauersteinen ermöglicht, sodass eine feste, stabile und möglichst wetterundurchlässige Mauer gebildet werden kann.Provision is preferably made for two or more transverse connection grooves to be provided in the second and/or the fourth side. With this arrangement, a multi-shell wall can be constructed in a simple manner using bricks arranged in a staggered manner. The presence of at least two cross-connecting grooves enables the connection of a brick with two bricks arranged next to it in a further layer, so that a solid, stable wall that is as impermeable as possible to the weather can be formed.
Weiters ist bevorzugt vorgesehen, dass in der ersten und/oder der dritten Seite zwei oder mehr Längsverbindungsnuten vorgesehen sind. Diese Ausbildung erhöht die Flexibilität der Mauersteine, indem bspw. ein größerer Mauerstein mit zwei kleineren Mauersteinen verbunden werden kann. Hierbei ist im verbundenen Zustand bspw. ein erster kleinerer Mauerstein mit einer ersten Längsverbindungsnut verbunden und ein zweiter kleinerer Mauerstein mit einer zweiten Längsverbindungsnut.Furthermore, it is preferably provided that two or more longitudinal connecting grooves are provided in the first and/or the third side. This design increases the flexibility of the bricks, for example by allowing a larger brick to be connected to two smaller bricks. Here, in the connected state, for example, a first, smaller brick is connected to a first longitudinal connection groove and a second, smaller brick is connected to a second longitudinal connection groove.
Bevorzugt ist vorgesehen, dass die erste Seite und die dritte Seite sowie die zweite Seite und die vierte Seite jeweils im Wesentlichen parallel zueinander angeordnet sind.It is preferably provided that the first side and the third side as well as the second side and the fourth side are each arranged essentially parallel to one another.
Bei einer bevorzugten Ausbildung ist vorgesehen, dass sich der Querschnitt der Längsverbindungsnut und/oder der Querverbindungsnut von der Nutöffnung weg kontinuierlich verbreitert. Besonders bevorzugt ist vorgesehen, dass die Längsverbindungsnut und/oder die Querverbindungsnut als Schwalbenschwanznut ausgebildet ist. Eine derartige Nutform hat den Vorteil, dass ein in der Nut angeordnetes, der Nutform entsprechendes Verbindungselement, bspw. ein Holzdübel, formschlüssig fest in der Nut gehalten wird. Weiters gibt es hierbei lediglich einen Platz für das Verbindungselement, wodurch beim Einführen des Verbindungselements die zu verbindenden Mauersteine ohne weiteres Zutun in die richtige Position zueinander gebracht werden.In a preferred embodiment, it is provided that the cross section of the longitudinal connection groove and/or the transverse connection groove widens continuously away from the groove opening. Provision is particularly preferably made for the longitudinal connection groove and/or the transverse connection groove to be designed as a dovetail groove. Such a groove shape has the advantage that a connecting element arranged in the groove and corresponding to the groove shape, for example a wooden dowel, is held firmly in the groove with a positive fit. Furthermore, there is only one place for the connecting element, which means that when the connecting element is inserted, the bricks to be connected can be brought into the correct position relative to one another without any further action.
Weiters ist bei einem erfindungsgemäßen Mauerstein bevorzugt vorgesehen, dass in zumindest einem Randbereich ein Falz angeordnet ist. Der Mauerstein weist hierbei eine Stufe in zumindest einem, bevorzugt zwei gegenüberliegenden Randbereichen auf. Die Stufe wird durch zwei Begrenzungen gebildet, die bevorzugt im Wesentlichen senkrecht zueinanderstehen. Bevorzugt sind, wenn zwei Falze vorgesehen sind, diese im Wesentlichen parallel zueinander. Der Falz ist hierbei zwischen zwei Seiten des im Wesentlichen quaderförmigen Mauersteins angeordnet, bevorzugt der Oberseite und einer weiteren Seite, bspw. der zweiten und/oder vierten Seite. Dieser Falz kann genutzt werden, um eine formschlüssige Verbindung in Querrichtung zum Falzverlauf mit einem anderen Mauerstein zu bilden. Hierzu ist bevorzugt vorgesehen, dass der Mauerstein an einer Oberseite in zwei gegenüberliegenden Randbereichen jeweils einen Falz aufweist und an der Unterseite in diesen zwei gegenüberliegenden Randbereichen jeweils einen Zapfen. Die Zapfen sind derart ausgebildet, dass sie in die Falze eines anderen Mauersteins, der die gleiche Falz-Zapfen Kombination aufweist, eingreifen können. Dadurch kann die Unterseite eines ersten Mauersteins in die Oberseite eines gleichartigen zweiten Mauersteins eingreifen und hierdurch verbunden werden. Bevorzugt sind die Höhe der Zapfen und die Tiefe der Falze im Wesentlichen gleich groß, sodass übereinanderliegende Steine gleicher Art bündig abschließen. Alternativ kann vorgesehen sein, dass die Höhe der Zapfen größer ist als die Tiefe der Falze, wodurch zwischen übereinanderliegenden Steinen ein Hohlraum entsteht, in welchem bspw. Luft angeordnet ist. Solch ein Hohlraum erhöht die Dämmwirkung der durch die Mauersteine gebildeten Mauer.Furthermore, in the case of a brick according to the invention, it is preferably provided that a fold is arranged in at least one edge region. The brick here has a Stage in at least one, preferably two opposite edge areas. The step is formed by two boundaries, which are preferably substantially perpendicular to each other. If two folds are provided, they are preferably essentially parallel to one another. In this case, the fold is arranged between two sides of the essentially cuboid brick, preferably the upper side and another side, for example the second and/or fourth side. This fold can be used to form a form-fitting connection in the transverse direction to the fold line with another brick. For this purpose, it is preferably provided that the brick has a fold on an upper side in two opposite edge regions and a tenon on the underside in each of these two opposite edge regions. The tenons are designed in such a way that they can engage in the rabbets of another brick that has the same rabbet-tenon combination. As a result, the bottom of a first brick can engage in the top of a similar second brick and be connected as a result. The height of the pegs and the depth of the folds are preferably essentially the same size, so that stones of the same type lying on top of one another end flush. Alternatively, it can be provided that the height of the pegs is greater than the depth of the folds, as a result of which a cavity is created between the bricks lying one on top of the other, in which space, for example, air is arranged. Such a cavity increases the insulating effect of the wall formed by the bricks.
Der bzw. die Falze ist bzw. sind bevorzugt derart angeordnet, dass die Längsöffnung einer Querverbindungsnut oder einer Längsverbindungsnut, bevorzugt vollständig, im Falz angeordnet ist. Die Nutöffnungen der Querverbindungsnut(en) bzw. der Längsverbindungsnut(en) münden in den entsprechenden Falz und sind hierbei direkt an der Außenseite des Mauersteins angeordnet, sodass eine einfache Verbindung mit einem anderen Mauerstein bspw. mithilfe eines Verbindungsdübels möglich ist. Die Längsöffnung erstreckt sich bevorzugt in einer zur Oberfläche des Mauersteins parallelen Fläche.The fold or folds is or are preferably arranged in such a way that the longitudinal opening of a transverse connection groove or a longitudinal connection groove, preferably completely, in Fold is arranged. The groove openings of the transverse connection groove(s) or the longitudinal connection groove(s) open into the corresponding fold and are arranged directly on the outside of the brick, so that a simple connection to another brick, for example using a connecting dowel, is possible. The longitudinal opening preferably extends in an area parallel to the surface of the brick.
Bevorzugt entspricht die Tiefe der Querverbindungsnut bzw. der Längsverbindungsnut im Wesentlichen der Ausdehnung des Falzes in der Tiefenrichtung der Nut. Hierbei liegt ein in der Nut angeordneter und darüber hinausragender Verbindungsdübel an der zur Tiefenrichtung der Nut senkrechten Begrenzung des Falzes an, sodass die Verbindung zwischen der Nut und dem Verbindungsdübel stabilisiert wird.The depth of the transverse connection groove or of the longitudinal connection groove preferably corresponds essentially to the extent of the fold in the depth direction of the groove. In this case, a connecting dowel arranged in the groove and protruding beyond it lies against the delimitation of the fold perpendicular to the depth direction of the groove, so that the connection between the groove and the connecting dowel is stabilized.
Bevorzugt ist ein weiterer Falz in einem Randbereich des Mauersteins angeordnet, der quer zu dem anderen Falz verläuft. Falls drei Randbereiche des Mauersteins einen Falz aufweisen, wird in der Draufsicht durch die Falze eine U-Form gebildet.A further fold is preferably arranged in an edge region of the brick which runs transversely to the other fold. If three edge areas of the brick have a fold, a U-shape is formed by the folds when viewed from above.
Weiters weist der Mauerstein bevorzugt eine Nut an der Oberseite auf, die senkrecht zu der Längsverbindungsnut und der Querverbindungsnut verläuft. Besonders bevorzugt verläuft die Nut im Wesentlichen parallel zu einem an der Oberseite des Mauersteins angeordneten Falz. Weiters ist die Nut bevorzugt durchgehend ausgebildet. In diese Nut kann bspw. ein quer zu einem ersten Mauerstein angeordneter zweiter Mauerstein angeordnet werden, um eine Verbindung herzustellen.Furthermore, the brick preferably has a groove at the top, which runs perpendicularly to the longitudinal connection groove and the transverse connection groove. The groove particularly preferably runs essentially parallel to a fold arranged on the upper side of the brick. Furthermore, the groove is preferably designed to be continuous. For example, a second brick arranged transversely to a first brick can be arranged in this groove in order to establish a connection.
Bevorzugt ist vorgesehen, dass die zumindest eine Längsverbindungsnut und die zumindest eine Querverbindungsnut im Wesentlichen den gleichen Querschnitt aufweisen. Dies ermöglicht die Verwendung von gleichen Verbindungsstücken, um sowohl in Längsverbindungsnuten als auch in Querverbindungsnuten eingreifen zu können.Provision is preferably made for the at least one longitudinal connection groove and the at least one transverse connection groove to have essentially the same cross section. This allows the same connectors to be used to engage both longitudinal and transverse connection grooves.
Die Längsverbindungsnut und/oder die Querverbindungsnut weist bevorzugt eine Fase an der Längsöffnung auf, um ein Einführen eines Verbindungselements, bspw. eines Holzdübels, zu erleichtern.The longitudinal connection groove and/or the transverse connection groove preferably has a chamfer on the longitudinal opening in order to make it easier to insert a connection element, for example a wooden dowel.
Die Längsverbindungsnut und/oder die Querverbindungsnut weisen bevorzugt einen über die Länge der Nut im Wesentlichen gleichbleibenden Querschnitt auf, um ein Einführen eines Holzdübels oder einer Feder zu ermöglichen bzw. zu erleichtern.The longitudinal connecting groove and/or the transverse connecting groove preferably have a cross section that is essentially constant over the length of the groove in order to enable or facilitate the insertion of a wooden dowel or a tongue.
Bei einer bevorzugten Ausführungsform weist zumindest eine Seite des Mauersteins ein Wetterprofil auf, welches im Querschnitt mehrere Vorsprünge umfasst, die dazu dienen, um Wasser besser abzuleiten.In a preferred embodiment, at least one side of the brick has a weather profile that includes, in cross-section, a plurality of protrusions that serve to better drain water.
Der Mauerstein weist weiters bevorzugt an seiner Unterseite eine weitere, bevorzugt durchgehende, Nut auf. Im mit anderen Mauersteinen verbundenen Zustand dient diese Nut als Luftvolumen, welches die Dämmung der Wand weiter verbessert.The brick also preferably has a further, preferably continuous, groove on its underside. When connected to other bricks, this groove serves as an air volume, which further improves the wall's insulation.
Die Nuten, insbesondere die Querverbindungsnut(en) sowie die Längsverbindungsnut(en), sowie ggf. der Falz und weitere Nuten sind bevorzugt durch Fräsen hergestellt.The grooves, in particular the transverse connection groove(s) and the longitudinal connection groove(s), and possibly the fold and other grooves are preferably produced by milling.
Die Erfindung betrifft weiters ein Set, umfassend zumindest einen erfindungsgemäßen Mauerstein sowie zumindest einen Verbindungsdübel, der ausgebildet ist, um in die Längsverbindungsnut und/oder die Querverbindungsnut formschlüssig eingreifen zu können. Hierdurch wird eine Verbindung geschaffen, die im Wesentlichen keine Bewegung des Verbindungsdübels quer zum Nutverlauf ermöglicht. Der Verbindungsdübel kann also lediglich durch eine Längsöffnung aus der Nut herausgezogen werden, um die Verbindung zu lösen. Da das einfache Herausziehen in vielen Fällen nur schwer durchzuführen ist, weil sich der Verbindungsdübel mit dem Mauerstein fest verbunden hat, ist es oftmals einfacher, den Verbindungsdübel bspw. mit einem Beil zu spalten, um die Verbindung zwischen dem Dübel und dem Mauerstein zu lösen.The invention further relates to a set comprising at least one brick according to the invention and at least one connecting dowel which is designed to be able to positively engage in the longitudinal connecting groove and/or the transverse connecting groove. This creates a connection that essentially does not allow any movement of the connecting dowel transverse to the course of the groove. The connecting dowel can therefore only be pulled out of the groove through a longitudinal opening in order to release the connection. Since it is difficult to simply pull it out in many cases because the connecting dowel is firmly connected to the brick, it is often easier to split the connecting dowel, for example with an axe, in order to loosen the connection between the dowel and the brick.
Bevorzugt ist vorgesehen, dass der Verbindungsdübel ausgebildet ist, um in die Längsverbindungsnut und/oder die Querverbindungsnut eines ersten Mauersteins eingreifen zu können und gleichzeitig in die Längsverbindungsnut und/oder die Querverbindungsnut eines zweiten Mauersteins eingreifen zu können, wodurch der erste und der zweite Mauerstein miteinander verbunden werden können. Der Verbindungsdübel kann hierbei verwendet werden, um zwei Mauersteine miteinander zu verbinden, indem der Verbindungsdübel sowohl in eine erste Nut eines ersten Mauersteins und in eine zweite Nut eines zweiten Mauersteins formschlüssig eingreift.It is preferably provided that the connecting dowel is designed to be able to engage in the longitudinal connecting groove and/or the transverse connecting groove of a first brick and at the same time to be able to engage in the longitudinal connecting groove and/or the transverse connecting groove of a second brick, whereby the first and the second brick are connected to one another can be connected. The connecting dowel can be used here to connect two bricks to one another by the connecting dowel engaging in a form-fitting manner both in a first groove of a first brick and in a second groove of a second brick.
Weiters ist bevorzugt vorgesehen, dass der Querschnitt des zumindest einen Verbindungsdübels im Wesentlichen dem Querschnitt der Längsverbindungsnut und/oder der Querverbindungsnut entspricht.Furthermore, it is preferably provided that the cross section of the at least one connecting dowel essentially corresponds to the cross section of the longitudinal connecting groove and/or the transverse connecting groove.
Der bzw. die Verbindungsdübel weist bzw. weisen bevorzugt zumindest eine Länge auf, die der Höhe des Mauersteins entspricht. Besonders bevorzugt ist die Länge des Verbindungsdübels größer als die Höhe des Mauersteins, sodass auch übereinander angeordnete Mauersteine einfach mithilfe eines Verbindungsdübels miteinander verbunden werden können. Die Länge des Verbindungsdübels entspricht bevorzugt zumindest der 1,5-fachen, besonders bevorzugt der zumindest 2-fachen, insbesondere der zumindest 2,5-fachen Länge der Längs- bzw. Querverbindungsnut eines Mauersteins. Dies ermöglicht eine stabile Verbindung der Mauersteine miteinander.The connecting dowel(s) preferably has/have at least a length which corresponds to the height of the brick. The length of the connecting dowel is particularly preferably greater than the height of the brick, so that bricks arranged one above the other can also be easily connected to one another using a connecting dowel. The length of the connecting dowel preferably corresponds to at least 1.5 times, particularly preferably at least 2 times, in particular at least 2.5 times the length of the longitudinal or transverse connecting groove of a brick. This enables a stable connection between the bricks.
Bevorzugt ist vorgesehen, dass der zumindest eine Mauerstein und der zumindest eine Verbindungsdübel aus unterschiedlichen Holzarten gefertigt sind. Besonders bevorzugt ist hierbei vorgesehen, dass der Mauerstein aus Fichtenholz und der Verbindungsdübel aus Buchenholz besteht. Durch diese Kombination ergibt sich eine besonders gute Verbindung zwischen dem Mauerstein und dem Verbindungsdübel. Alternativ ist vorgesehen, dass der Mauerstein und der Verbindungsdübel aus der gleichen Holzart gefertigt sind.Provision is preferably made for the at least one brick and the at least one connecting dowel to be made from different types of wood. In this case, it is particularly preferred that the brick is made of spruce wood and the connecting dowel is made of beech wood. This combination results in a particularly good connection between the brick and the connecting dowel. Alternatively, it is provided that the brick and the connecting dowel are made of the same type of wood.
Weiters ist bevorzugt vorgesehen, dass der Verbindungsdübel derart ausgebildet ist, dass der erste Mauerstein und der zweite Mauerstein einander im verbundenen Zustand berühren. Der Verbindungsdübel ist in dieser Ausführungsform bspw. derart ausgebildet, dass die jeweils in die Nuten, insbesondere Längs- bzw. Querverbindungsnuten, einführbaren Bereiche direkt aneinander angrenzen. Beispielsweise weist der Verbindungsdübel im Querschnitt zwei direkt aneinander anschließende Schwalbenschwänze auf.Furthermore, it is preferably provided that the connecting dowel is designed in such a way that the first brick and the second brick touch each other in the connected state. In this embodiment, the connecting dowel is designed, for example, in such a way that the areas that can be inserted into the grooves, in particular longitudinal or transverse connecting grooves, are directly adjacent to one another. For example, the connecting dowel has two dovetails directly adjoining one another in cross section.
Weiters ist bevorzugt vorgesehen, dass der Verbindungsdübel in Längsrichtung Rillen aufweist (geriffelt ist), wodurch ein eventuell zur Verbindung verwendeter Klebstoff, bspw. Leim, besser am Dübel haften bleibt.Furthermore, it is preferably provided that the connecting dowel has grooves (is corrugated) in the longitudinal direction, as a result of which any adhesive used for the connection, for example glue, better adheres to the dowel.
Weiters weist der Verbindungsdübel bevorzugt eine Fase auf, die ein Einführen des Verbindungsdübels in die entsprechende Nut des Mauersteins erleichtert.Furthermore, the connecting dowel preferably has a chamfer, which facilitates the insertion of the connecting dowel into the corresponding groove in the brick.
Die Erfindung betrifft weiters eine aus einem erfindungsgemäßen Set aufgebaute Mauer, bei welcher Verbindungsdübel in Längs- bzw. Querverbindungsnuten zumindest eines Mauersteins angeordnet sind. Hierbei ist bevorzugt vorgesehen, dass die Verbindungsdübel mithilfe von Holzleim, insbesondere Kaseinleim, in den Längs- bzw. Querverbindungsnuten befestigt sind.The invention further relates to a wall constructed from a set according to the invention, in which connecting dowels are arranged in longitudinal or transverse connecting grooves of at least one brick. It is preferably provided here that the connecting dowels are fastened in the longitudinal or transverse connecting grooves with the aid of wood glue, in particular casein glue.
Bevorzugt ist eine zwei-, drei- oder mehrschalige Mauer vorgesehen, bei welcher die einzelnen Schalen mithilfe der Querverbindungsnuten miteinander verbunden sind.A wall with two, three or more shells is preferably provided, in which the individual shells are connected to one another by means of the transverse connecting grooves.
Die Erfindung wird nachfolgend anhand eines in der Zeichnung schematisch dargestellten Ausführungsbeispiels näher erläutert. In dieser zeigen
