Description

Die Erfindung betrifft einen Stein, insbesondere Blockstein und ein Verfahren zu dessen Herstellung, mit zwei Längswänden, die eine Außenwand und eine Innenwand bilden, wobei die Außenwand mit einem isolierenden und die Innenwand mit einem betonartigen Werkstoff versehen ist.The invention relates to a stone, in particular Block and a method for its production, with two longitudinal walls, which have an outer wall and an inner wall form, the outer wall with an insulating and the inner wall with a concrete-like material is provided.

Ein gattungsgemäßer Stein ist beispielsweise aus der EP 0 751 266 bekannt.A generic stone is for example from the EP 0 751 266.

Der in der genannten Druckschrift offenbarte Stein weist zwei Längswände auf, die eine Außenwand und eine Innenwand bilden. Dabei sind beide Längswände durch zwei rechtwinklig zu den Längswänden verlaufende Querstege miteinander verbunden. Bezogen auf die seitlichen Stirnseiten (Stirnseite der Außen- und der Innenwand) sind die Querstege dabei etwas nach innen versetzt.The stone disclosed in said document has two longitudinal walls, which has an outer wall and a Form inner wall. Both longitudinal walls are through two transverse webs extending at right angles to the longitudinal walls connected with each other. Relative to the lateral End faces (front of the outer and inner wall) the crossbars are slightly shifted inwards.

Die Innenwand und die mit der Innenwand verbundenen Querstege sind einstückig aus Beton oder einem betonähnlichem Material gefertigt, während die Außenwand aus Polystyrol, also einem dämmenden Werkstoff, hergestellt ist. Der offenbarte Stein ist sowohl an der Steinoberseite als auch an der Steinunterseite offen, so daß der Stein beispielsweise im Verbund geschoßhoch verbaut und der zwischen der Außen- und Innenwand verbleibende freie Raum vergießbar ist. Dabei erfolgt das Vergießen der Steine in nachteilhafter Weise erst vor Ort, d.h. auf der Baustelle.The inner wall and the one connected to the inner wall Crossbars are made in one piece from concrete or a concrete-like one Material made while the outer wall made of polystyrene, ie an insulating material is. The revealed stone is both on the Stone top as well as at the stone bottom open, so that the stone, for example, in the composite projectile high installed and remaining between the outer and inner wall free space is pourable. This is done Potting the stones in a disadvantageous way before Place, i. on the site.

Weitere bekannte Steine sind in der DE 43 18 578 A1, der DE 295 10 640 A1, der DE 297 09 614 A1 und der DE 298 12 981 beschrieben.Further known stones are in DE 43 18 578 A1, DE 295 10 640 A1, DE 297 09 614 A1 and DE 298 12 981 described.

Die offenbarten Steine bestehen ebenfalls aus zwei Querstegen und zwei Längswänden, die eine Außenwand und eine Innenwand bilden. Der zwischen den Wänden liegende Hohlraum wird ebenfalls zur Befüllung mit Beton verwendet. Bei den bisher bekannten Steinen kann außerdem eine Isolierungseinlage zur Wärmedämmung vorgesehen sein.The revealed stones also consist of two Crossbars and two longitudinal walls, an outer wall and form an inner wall. The one between the walls lying cavity is also for filling with Concrete used. In the previously known stones can also provided an insulation insert for thermal insulation be.

Nachteilig bei allen bisher bekannten Steinen ist, daß die aus einem dämmenden Material bestehende Außenwand in ihrer Herstellung durch die für die Verbindung mit den Querstegen der Innenwand notwendigen Querteile teuer und aufwendig ist. Darüber hinaus ist zur Verbindung der Außenwand mit der Innenwand bzw. den Querstegen eine entsprechende Präzision notwendig, die Zeit benötigt und Kosten verursacht. Die speziellen Verbindungselemente, sowohl die Querstege als auch die Querteile sind jedoch notwendig, damit der Stein in vorteilhafter Weise mit Beton verfüllt werden kann und alle Belastungsanforderungen erfüllt.A disadvantage of all previously known stones is that the exterior wall made of insulating material in their manufacture by those for connection with the transverse webs of the inner wall necessary cross members expensive and expensive. In addition, to the connection the outer wall with the inner wall or the transverse webs a corresponding precision necessary, the Time needed and costs incurred. The special ones Connecting elements, both the transverse webs and the However, cross pieces are necessary to allow the stone in can advantageously be filled with concrete and meets all load requirements.

Von Nachteil bei allen bisher bekannten Steinen ist außerdem, daß durch die für die Verbindung der Außenwand mit der Innenwand notwendigen Querstege anteilsmäßig hohe Produktions- und Materialkosten entstehen.A disadvantage of all previously known stones in addition, that by the for the connection of the outer wall with the inner wall necessary transverse webs proportionately high production and material costs arise.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, einen Stein mit den bekannten vorteilhaften Eigenschaften, insbesondere einer guten Dämmung, und ein Verfahren zu dessen Herstellung zu schaffen, der eine einfache, schnelle, stabile und dauerhafte Befestigung der Außenwand an der Innenwand ermöglicht, der kostengünstig und bei Bedarf in einfacher Weise vollständig im Werk herstellbar ist.The present invention is therefore the task underlying a stone with the well-known beneficial Properties, in particular a good insulation, and to provide a method for its production, the a simple, fast, stable and durable attachment the outer wall on the inner wall allows the cost-effective and in a simple way if required completely can be produced in the factory.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß die Außenwand und/oder die Innenwand eine auf die jeweils andere Längswand gerichtete Aussparung aufweist, die an einer Steinunterseite oder einer Steinoberseite und den seitlichen Stirnseiten des Steines wenigstens teilweise von der jeweiligen Längswand begrenzt ist, und die Aussparung mit einem aushärtenden Material verfüllt ist. According to the invention, this object is achieved in that the outer wall and / or the inner wall one on top of each having another longitudinal wall directed recess, those at a stone base or a stone top and the lateral ends of the stone at least is partially bounded by the respective longitudinal wall, and the recess with a hardening material is filled.

Dadurch, daß die Außenwand und/oder die Innenwand eine Aussparung aufweist, die an die jeweils andere Längswand angrenzt, läßt sich durch die Verfüllung der Aussparung mit einem aushärtenden Material eine sichere und stabile Verbindung zwischen den beiden Längswänden herstellen. Separate Querstege, die die Außenwand mit der Innenwand verbinden, können somit entfallen. Dadurch läßt sich der Baustein anteilsmäßig günstiger herstellen. Insbesondere entfallen die bisherigen konstruktiv aufwendigen und teuren Verbindungselemente, wie z.B. die Querstege und die Querteile, mit denen die Innen- und die Außenwand miteinander verbunden werden mußten.Characterized in that the outer wall and / or the inner wall a Recess which, to the respective other longitudinal wall adjoins, can be through the filling of the recess with a hardening material a safe and stable connection between the two longitudinal walls produce. Separate transverse webs that with the outer wall connect the inner wall, can thus be omitted. Thereby can the block proportionally cheaper produce. In particular, the previous design omitted elaborate and expensive fasteners, such as. the transverse webs and the crosspieces with which the inner and the outer wall are connected had to be.

Dadurch, daß die Aussparung an der Steinunterseite oder Steinoberseite von der jeweiligen Längswand begrenzt ist, ist es möglich, den Stein bereits im Werk mit dem auszuhärtenden Material zu verfüllen. Somit lassen sich auch einzelne Steine direkt verbauen, ohne daß vor Ort noch zusätzliche Füllarbeiten, wie bei Steinen üblich, notwendig sind.Because of the recess on the underside of the stone or stone top bounded by the respective longitudinal wall is, it is possible the stone already in the factory to fill with the material to be cured. Consequently can also block individual stones directly, without that on-site additional filling work, as in Stones are common, necessary.

Dadurch, daß die Aussparung an den seitlichen Stirnseiten des Steines von der jeweiligen Längswand begrenzt ist, kann der Stein in vorteilhafter Weise verfüllt werden, ohne daß das einzufüllende Material auslaufen kann.The fact that the recess on the lateral end faces of the stone bounded by the respective longitudinal wall is, the stone can be filled in an advantageous manner be without the einzufüllende material leak can.

Eine Befüllung mit dem aushärtenden Material kann dabei je nach Ausgestaltung und Lage des Steines bei seiner Herstellung entweder von der Steinunterseite oder der Steinoberseite erfolgen. Durch das Aushärten des Materials entsteht eine stabile und dauerhafte Verbindung zwischen den beiden Längswänden. Je nach Wahl des aushärtenden Materials läßt sich die Zeitspanne, bis das eingefüllte Material ausgehärtet ist, variieren.A filling with the hardening material can thereby depending on the design and location of the stone its production either from the stone base or the top of the stone. By curing The material creates a stable and lasting Connection between the two longitudinal walls. Depending on Choice of the hardening material can be the time span, until the filled material has hardened, vary.

In vorteilhafter Weise lassen sich mit Hilfe der Aussparung und des aushärtenden Materials verschieden dicke Außenwände mit der Innenwand verbinden. Dadurch läßt sich die Isolierstärke der Außenwand stufenlos und variabel gestalten.Advantageously, can be with the help of the recess and the thermosetting material differently connect thick outer walls with the inner wall. Thereby can the insulation thickness of the outer wall is infinitely variable and variable.

In überraschender und nicht naheliegender Weise hat der Erfinder erkannt, daß die Schalldämmung bzw. die Frequenzen durch die zwei verschiedenen Betonschichten positiv beeinflußt bzw. gedämpft werden. Dies gilt unabhängig davon, aus welcher Richtung der Schall bzw. die Frequenzen auf den Stein treffen.In a surprising and unobvious way has the inventor recognized that the sound insulation or the Frequencies through the two different concrete layers be positively influenced or damped. this applies regardless of which direction the sound or hit the frequencies on the stone.

Erfindungsgemäß kann ferner vorgesehen sein, daß vertikale Vorsprünge der Außen- und/oder Innenwand die Aussparung an den seitlichen Stirnseiten begrenzen, wobei sie sich vorzugsweise in Richtung der Öffnung der Aussparung verdicken.According to the invention may also be provided that vertical Projections of the outer and / or inner wall the Limit recess at the lateral end faces, preferably in the direction of the opening thicken the recess.

Durch das Verdicken der vertikalen Vorsprünge, die die Aussparung an den seitlichen Stirnseiten begrenzen, wird nach dem Verfüllen mit dem aushärtenden Material eine besonders stabile und sichere Verbindung zwischen den beiden Längswänden geschaffen. By thickening the vertical projections, which the Limit recess at the lateral end faces, will after filling with the hardening material a particularly stable and secure connection between created the two longitudinal walls.

Von Vorteil ist es, wenn die vertikalen Vorsprünge derart ausgebildet sind, daß die Aussparung eine schwalbenschwanzförmige Form aufweist.It is advantageous if the vertical projections are formed such that the recess a having dovetail shape.

Der Erfinder hat in nicht naheliegender Weise erkannt, daß sich durch die schwalbenschwanzförmige Ausgestaltung der Aussparung eine besonders sichere, stabile und einfach herzustellende Verbindung zwischen den beiden Längswänden erstellen läßt.The inventor has recognized in a non-obvious way, that by the dovetail-shaped configuration the recess a particularly safe, stable and easy to make connection between the create two longitudinal walls.

In einer konstruktiven Ausgestaltung der Erfindung kann ferner vorgesehen sein, daß eine Rückwand der Aussparung Verzahnungselemente aufweist, und daß die Längswand, die an die mit der Aussparung versehene andere Längswand angrenzt, im Bereich der Aussparung mit Verzahnungselementen versehen ist.In a constructive embodiment of the invention can also be provided that a rear wall of the Recess has toothed elements, and that the Longitudinal wall, which is provided with the recess another longitudinal wall adjacent, in the region of the recess provided with toothing elements.

In Versuchen hat sich herausgestellt, daß sich die Qualität und die Stabilität der Verbindung zwischen der Außenwand und der Innenwand durch die Verzahnungselemente deutlich erhöhen läßt. Besonders vorteilhaft ist es dabei, wenn sowohl die Rückwand als auch die Längswand, die an die mit der Aussparung versehene andere Längswand angrenzt, Verzahnungselemente aufweist. Durch die Verzahnungselemente erhält das aushärtende Material eine Vielzahl von vorteilhaften Ansatzstellen, an denen eine besonders hoch belastbare Verbindung möglich ist. In experiments it has been found that the Quality and stability of the connection between the outer wall and the inner wall by the toothing elements can increase significantly. Especially advantageous It is there when both the back wall and the Longitudinal wall, which is provided with the recess adjacent other longitudinal wall, has toothed elements.

In einer Weiterbildung der Erfindung kann ferner vorgesehen sein, daß die Verzahnungselemente Hinterschneidungen aufweisen.In a further development of the invention can also be provided be that the toothing elements undercuts exhibit.

Durch die Hinderschneidungen der Verzahnungselemente läßt sich eine besonders vorteilhafte Verbindung zwischen dem aushärtenden Material und den beiden Längswänden erreichen.Due to the obstruction of the toothed elements can be a particularly advantageous connection between the hardening material and the two longitudinal walls to reach.

In einer konstruktiven Ausgestaltung der Erfindung kann ferner vorgesehen sein, daß die im Bereich der seitlichen Stirnseiten angeordneten Verzahnungselemente als Verbindungselemente für die mit der Aussparung versehene Längswand ausgebildet sind.In a constructive embodiment of the invention may be further provided that in the field of lateral end faces arranged toothing elements as connecting elements for those with the recess provided longitudinal wall are formed.

Durch die Ausbildung der im Randbereich angeordneten Verzahnungselemente als Verbindungselemente läßt sich die mit der Aussparung versehene Längswand in vorteilhafter Weise an der anderen Längswand bzw. an deren Verbindungselemente anbringen. Dadurch wird vor dem Einfüllen des aushärtenden Materials in die Aussparung eine Verbindung zwischen den beiden Längswänden erzeugt, so daß sich das aushärtende Material in vorteilhafter Weise einfüllen und verfestigen läßt.Due to the formation of the arranged in the edge region Gear elements as connecting elements can be the provided with the recess longitudinal wall in an advantageous Way on the other longitudinal wall or at the Attach connecting elements. This will be before the Fill the hardening material into the recess creates a connection between the two longitudinal walls, so that the thermosetting material in an advantageous Fill and solidify manner.

Von Vorteil ist es, wenn mittels der vertikalen Vorsprünge und der Verbindungselemente eine schwalbenschwanzartige Verbindung zwischen den beiden Längswänden bildbar ist. It is advantageous if by means of the vertical projections and the connecting elements a dovetail-like Connection between the two longitudinal walls is picturable.

Durch die schwalbenschwanzartige Verbindung läßt sich die Außenwand in besonders vorteilhafter Weise durch ein Zusammenstecken mit der Innenwand verbinden. Somit kann das aushärtende Material in vorteilhafter Weise in die Aussparung eingebracht werden.By dovetail connection can be the outer wall in a particularly advantageous manner connect a mating with the inner wall. Consequently can the curing material in an advantageous manner be introduced into the recess.

The vertical projections 5 are in this case designed so that they are over the entire Height of the recess 3 extend and towards an opening 6 of the recess 3 thicken. The Thickening of the vertical projections 5 takes place such that the inner sides adjacent to the recess 3 the vertical projections 5 a bend in Direction of the central axis of the stone, which the recess 3 is a dovetail-like Form receives.

Wie in Fig. 1 ebenfalls ersichtlich, weist die Außenwand 1 in ihrem an die Aussparung 3 angrenzenden Bereich und einer Rückwand 7 der Aussparung 3, Verzahnungselemente 8 auf. Dabei weisen die Verzahnungselemente 8 Hinterschneidungen 9 auf und sind damit schwalbenschwanzförmig ausgebildet.As can also be seen in Fig. 1, the outer wall 1 in its adjacent to the recess 3 area and a rear wall 7 of the recess 3, gear elements 8 on. In this case, the gear elements 8 undercuts 9 and are so dovetail-shaped.

Die im Bereich der seitlichen Stirnseiten der Außenwand angeordneten Verzahnungselemente 8 sind zur Erfüllung einer weiteren Funktion als Verbindungselemente 8a ausgebildet. Dabei entspricht die Krümmung der Verbindungselemente 8a, indem an die vertikalen Vorsprünge 5 angrenzenden Bereich, der Biegung der vertikalen Vorsprünge 5. Dadurch läßt sich die Außenwand 1 mittels der Verbindungselemente 8a in vorteilhafter Weise in die Aussparung 3 der Innenwand 2 einstecken. Somit läßt sich das aushärtende Material 4 in eine stabile, mittels einer Schwalbenschwanzverbindung aus der Außenwand 1 und der Innenwand 2 gebildete Form einspritzen.The in the area of the lateral end faces of the outer wall arranged gear elements 8 are to fulfill another function as connecting elements 8a formed. The curvature corresponds to the Connecting elements 8a, by the vertical projections 5 adjacent area, the bend of the vertical Projections 5. This allows the outer wall 1 by means of the connecting elements 8a in an advantageous Insert manner into the recess 3 of the inner wall 2. Thus, the curing material 4 can be in a stable, by means of a dovetail connection the outer wall 1 and the inner wall 2 formed shape inject.

Um ein Auslaufen des aushärtenden Materials zu verhindern, weist der Stein, wie in Fig. 3 ersichtlich, an der Steinunterseite 10 ein horizontales Querelement 11 auf, das die Aussparung in diesem Bereich begrenzt. Das horizontale Querelement 11 ist dabei derart ausgebildet, daß es sich in Richtung der Öffnung 6 der Aussparung 3 verjüngt. Somit ist die Aussparung 3 an drei Seiten von Querelementen 5, 11 begrenzt. Die Aussparung 3 kann dabei von der Steinoberseite 12 her verfüllt werden.To prevent leakage of the hardening material, the stone indicates, as can be seen in FIG the stone bottom 10 a horizontal cross member 11th on that limits the recess in this area. The horizontal cross member 11 is designed in this case, that it is in the direction of the opening 6 of the recess 3 rejuvenated. Thus, the recess 3 at three Pages bounded by cross members 5, 11. The recess 3 can be filled from the top stone 12 ago become.

Wie aus Fig. 1 und Fig. 3 erkennbar, ist die Innenwand 2 mit zwei Sackbohrungen 13 versehen. Durch die Sackbohrungen 13 als Grifflöcher für eine Hand oder einen Kran läßt sich der Stein in einfacher Weise auf der Baustelle handhaben und verbauen. Um ein schnelles und exaktes Verbauen der Steine gewährleisten zu können, sind die Außenwände 1 und/oder die Innenwände 2 an ihren Stirnseiten bzw. an der Steinunterseite 10 und der Steinoberseite 12 mit entsprechenden Nuten und Federn versehen.As can be seen from FIGS. 1 and 3, the inner wall is 2 provided with two blind holes 13. Through the blind holes 13 as handle holes for a hand or a Crane can be the stone in a simple way on the Handling and obstruct construction site. To a fast and to be able to ensure exact installation of the stones, are the outer walls 1 and / or the inner walls 2 at their faces or on the stone bottom 10 and the stone top 12 with corresponding grooves and Provided feathers.

Eine verfahrensmäßige Herstellung des Steines kann beispielsweise dadurch erfolgen, daß die Innenwand 2 mit der Kontur der Aussparung 3 in üblicher Weise in einer Form durch Einbringen von Beton vorgefertigt wird. Anschließend kann die Außenwand 1 aus isolierenden Werkstoff, z.B. Polystyrol (Markenzeichen Styropor), mit der auf diese Weise vorgefertigten Innenwand 2 zusammengesteckt werden. Dabei wird mittels einer Presse derart nachgepreßt, daß die Außenwand 1 und Innenwand 2 an der Steinunterseite 10 bzw. der Steinoberseite 12 eine plane Fläche bilden.A procedural production of the stone can For example, take place in that the inner wall. 2 with the contour of the recess 3 in the usual way in prefabricated a form by introducing concrete becomes. Subsequently, the outer wall 1 of insulating Material, e.g. Polystyrene (trademark Styrofoam), with the prefabricated interior wall in this way 2 are put together. It is by means of a Pressed in such a way that the outer wall 1 and Inner wall 2 on the stone bottom 10 and the stone top 12 form a flat surface.

Nach dem Nachpressen der Längswände 1, 2 kann das aushärtende Material 4, beispielsweise ein leichtflüssiger Beton, in die Aussparung 3 gefüllt werden. Das Einfüllen kann dabei mittels einer Düse und einer Betonpumpe erfolgen.After pressing the longitudinal walls 1, 2, the curing Material 4, for example, a light liquid Concrete to be filled in the recess 3. The It can be filled with a nozzle and a concrete pump respectively.

Nach dem Einfüllen des aushärtenden Materials kann der Stein einer bekannten Fräseinrichtung zugeführt und auf der Ober- und/oder Unterseite maßgenau gefräst werden.After filling the curing material of the Stone fed to a known milling device and Milled on the top and / or bottom accurately become.

In einem alternativen Verfahren kann die Außenwand 1 soweit auf die Innenwand 2 gesteckt werden, daß das horizontale Querelement 11 mit der Außenwand 1 eine an der Steinunterseite geschlossene Fläche bildet. Dadurch kann das aushärtende Material 4 bereits vor dem Pressen eingefüllt werden.In an alternative method, the outer wall 1 as far as the inner wall 2 are plugged that the horizontal cross member 11 with the outer wall 1 a the stone base forms closed surface. Thereby can the curing material 4 before the Presses are filled.

In vorteilhafter Weise kann auf die Steinoberseite 12 eine Trennschicht, beispielsweise aus einer pulverförmigen Schicht wie z.B. Sand, aufgebracht werden, so daß bei einem Stapeln von mehreren Steinen eine Bindung zwischen den Steinen verhindert wird.Advantageously, on the stone top 12th a release layer, for example of a powdery Layer such as e.g. Sand, be applied, so that in a stacking of several stones a bond between the stones is prevented.

Ein Einfüllen des aushärtenden Materials kann in besonders vorteilhafter Weise dadurch erfolgen, daß das aushärtende Material 4 entsprechend dem Volumen der Aussparung 3 dosiert eingefüllt wird.A filling of the hardening material can in particular advantageously done by the curing material 4 according to the volume of Recess 3 is metered filled.

Selbstverständlich kann die Aussparung 3 sowohl in die Außenwand 1, wie in die Innenwand 2 eingebracht werden. In einer alternativen Ausgestaltung kann dabei auch vorgesehen sein, daß sowohl die Außenwand 1 als auch die Innenwand 2 eine Aussparung 3 aufweist.Of course, the recess 3 in both the Outside wall 1, as introduced into the inner wall 2. In an alternative embodiment can thereby Also be provided that both the outer wall 1 as also the inner wall 2 has a recess 3.
