Definitions
- the invention relates to a wall element for creating a wall, in particular a large-area formwork wall, from a plurality of wall elements which abut one another with their side abutting edges, the wall element having a vertical base plate in the installed state with straight and mutually parallel side abutting edges on the longitudinal sides of the base plate .
- Wall elements according to the invention are used in particular to create prefabricated large-area formwork walls.
- the invention can also be used for other types of wall elements with which, for example, walls are erected as conversions to exhibition stands or room partition walls.
- Large-area formwork walls prefabricated as such walls have the advantage that there are as few joints as possible in the wall area, since these are relatively complex to work on both during assembly and in treatment for the finished wall surface (formwork and supports in the assembled state for concreting the walls , Bandages and filling of the joints for smooth wall surfaces).
- Such prefabricated large-area formwork walls are currently only known from wood-based panels, but due to their combustibility and rotability, for example, they do not always meet the requirements that are placed on a building structure for external wall surfaces.
- plate-shaped combinable wall elements which have either a single wedge-shaped hooking projection protruding laterally in the center on the longitudinal sides of the plates or a hooking recess which fits centrally with the hooking projection and extends into the plate.
- the attachment of one wall element is suspended in the recess of another wall element, so that the abutting edges of two adjacent wall elements are pulled together.
- German Patent No. 2 165 977 discloses plate-shaped wall elements which can be combined to form a shell concrete wall which can be filled with a filler.
- the wall elements In order to place the wall elements next to one another, the wall elements have rectangular, stepped cutouts on the side abutting edges and pegs fitting into them that protrude beyond the side abutting edges.
- the invention solves the problem of how wall elements of the type mentioned at the outset can be designed such that they can also be produced in a relatively small size from material other than wood material, in particular also, for example, from cement-bound material, and can be quickly attached to one another to form a large-area wall.
- a second wall element for example with a construction crane, can be hung relatively easily into a wall element that has already been set up, by raising the second wall element with its attachment attachment to the level of the insertion recess of the first double wall element and then inserting it into the insertion recess, after which it is inserted is lowered and thereby slides with the lower end edge of its attachment lug on the lower boundary edge of the insertion recess into it until the abutting edges meet.
- the assembly also has the advantage that the double wall element to be hooked in with the flat outer sides of the Hook-in lugs on the base-side flat boundary surfaces of the hook-in recesses are also guided transversely to the base plates because the hook-in lugs engage between them due to their arrangement on the inside of the base plates.
- suspension lugs and the suspension recesses Due to the arrangement of the suspension lugs and the suspension recesses on the inside of the base plates, each seen from the outside behind the abutting edges, the suspension lugs and suspension recesses are also covered outwards after the assembly of the double wall elements, so that from the outside only the straight butt joints between the adjacent ones Bump edges are visible.
- Double wall elements are preferably used to erect large-area composite formwork walls in which the base plates e.g. are firmly connected to each other via spacers.
- Double wall elements according to the invention offer the further advantage that, due to their stability, they can be put together to form a large double wall, essentially without or with only a few support and formwork aids.
- the acute angle which the lower end edges of the attachment lugs and the lower boundary edges of the attachment recesses form with the plane of the adjacent abutting edge, should preferably not be too obtuse and not too acute.
- the attachment lugs and attachment recesses can also be designed differently, but the embodiments with obliquely downward lower edges are preferred.
- the insertion inserts and the insertion recesses are laterally offset from the plane of the respectively adjacent abutting edge, so that a fold is present on the longitudinal sides of the base plates having the insertion attachment, into which the relevant longitudinal side of the adjacent base plate, which has the insertion recess engages, and the butt joint is completely covered from the inside.
- suspension lugs can be flush with the inside of the base plates, the suspension lugs and plate parts delimiting the suspension recesses are preferably placed on the flat inner sides of the base plates.
- the attachment lugs and the plate parts delimiting the insertion recesses can be placed as individual pieces on the inside of the base plate.
- the suspension lugs and / or the suspension recesses are each formed on a bar that runs through the height of the base plates.
- a simple production of the attachment projection and the insertion recess can be achieved by cutting out an elongated strip from a plate, which has the insertion attachment and thus forms the "negative" of a further strip which has the insertion recess.
- the two different strips can then be mounted on the respective long side of the base plates. In both cases, by cutting the base plates, any waste that would otherwise have to be disposed of can be used for the formation of the suspension lugs and the plate parts delimiting the suspension recesses.
- each longitudinal side of the base plates preferably has a plurality of attachment lugs or attachment recesses. This makes it possible to achieve a more stable connection between the adjacent double wall elements.
- the distribution density of suspension attachments or suspension recesses on the respective longitudinal sides can be greater in the lower region of the double wall element than in the upper region thereof. This ensures a higher connection strength in the lower area, in which, in the application form of the double-wall elements as formwork panel elements, there is a higher load due to the pressure of the liquid concrete poured between the base plates.
- the suspension lugs are each formed by individual plates placed on the base plate, intermediate pieces can be built into the gaps between the suspension lugs, which results in a more stable construction and a better positional accuracy of the suspension lugs and also the joint edge in the area between successive ones Attachment approaches can be covered by intermediate pieces protruding over the edge of the joint.
- Such a cover can also be achieved with the above-mentioned bar, which carries the attachment lugs, if it extends laterally beyond the edge of the joint.
- the suspension recesses can, apart from the required play, be complementary to the suspension lugs. However, it is preferred that the height of the mounting recesses measured parallel to the abutting edges is greater than the relevant height of the mounting lugs. This favors the assembly of the double wall elements.
- the double wall element consisting of one is advantageous cement-bound material, made of plasterboard or wood.
- the choice of material is made according to the respective application, ie the use as a partition or the like or for a lost formwork.
- the double-wall elements can be assembled on site to form the double wall, it is preferred according to the invention to assemble and connect them together in the factory to form a prefabricated large-area double wall, preferably by gluing, but also with the aid of other types of connection such as screwing, riveting or dowelling and The like.
- the invention therefore also relates to such a prefabricated double wall.
- fittings as well as all necessary openings such as doors, windows, openings and the like can already be provided in the factory.
- the double wall element has two base plates 1, which run parallel to one another.
- the two base plates 1 are in the embodiment shown by means of spacers 2 with each other connected and are held firmly by them in their parallel position.
- spacers 2 with each other connected and are held firmly by them in their parallel position.
- Lateral abutting edges 15, 16 are formed from the two long sides of the base plates 1 and lie bluntly on the abutting edges of the base plates of the respectively adjacent double wall elements after the double wall elements have been assembled.
- plate-shaped suspension lugs 3 protrude outward beyond the joint edge 15, according to FIGS. 1 a and 1 b, on the mutually facing inner sides of the base plates 1, the plate plane of which therefore runs parallel to the base plates.
- These suspension lugs 3 can be glued, screwed or otherwise connected to the base plate 1.
- the lower end edge 6 of the plate-shaped suspension lugs 3 projecting outward beyond the abutting edge 15 extends obliquely downwards from the plane of the abutting edge 15 at an angle which in the exemplary embodiment is 45 °.
- the hanging lugs 3 are designed as single plate pieces, between which intermediate pieces 4 also connected to the base plate 1 are inserted, the hanging lugs 3 according to FIG. 1b are designed on a bar 9 common to them.
- FIGS. 2a and 2b in a perspective view, 16 recesses 7 are formed behind the other joint edge, each of which is delimited at the top and bottom by two plate parts 8.
- the lower boundary edge 10 of the suspension recesses 7 runs at the same angle as the lower end edge 6 of the suspension lugs 3 towards the center of the base plate 1 downwards.
- the plate parts 8 as well as the attachment lugs 3 are placed on the base plate 1 and glued, screwed or connected in some other way.
- the plate parts 8 are as Single pieces executed, whereas in the embodiment from FIG. 2b they are formed on a bar 9a common to them.
- the double wall elements can therefore be put together in such a way that the attachment lugs 3 of one double wall element engage in the suspension recesses 7 of the other double wall element, the abutting edges 15, 16 of the double wall elements lying on one another. Therefore, the composite double wall elements are firmly interlocked.
- the gaps between the rhombic suspension lugs 3 are filled on the inside of the base plate 1 by also plate-shaped rhombic intermediate pieces 4, which protrude slightly beyond the joint edge 15 with their outer side edge, so that their protruding side edge and the suspension lugs 3 on the one hand and the joint edge 15 on the other hand a fold 5 is limited.
- the also rhombic plate parts 8, between which the suspension recesses 7 are formed, are offset against the abutting edge 16, so that when two double wall elements are put together, the longitudinal side of the base plate 1 forming the abutting edge 16 of one double wall element in the fold 5 of the relevant base plate 1 of the other Double wall element can intervene and therefore the butt joint between the butt edges 15 and 16 is covered from the inside.
- Corresponding covering takes place in the embodiment from FIG. 1b with the aid of the strip 9 projecting with its continuous part over the abutting edge 15.
- the hanging recesses 7 have a greater clearance than the hanging lugs 3, as a result of which the hanging lugs 3 can be easily inserted laterally into the hanging recesses 7.
- a double wall element 11 is just fitted into a double wall element 12, which in turn is already firmly fitted into a double wall element 13.
- the double wall element 11 When fitting the double wall element 11 in that Double wall element 12, the double wall element 11 is lifted, for example with the help of a construction crane, and laterally inserted with the hanging lugs 3 into the hanging recesses 7 of the other double wall element 12 and then lowered, so that the hanging lugs 3 slide down and into the lower boundary edges 10 of the hanging recesses 7 until the abutting edges 15 and 16 of the base plates 1 of the double wall elements 11, 12 meet.
- the double wall elements are interlocked with one another in a form-fitting manner, as shown for the double wall elements 12 and 13 on the left of FIG. 3.
- the individual double wall elements can be glued to one another or otherwise fixed to one another, in particular assembled to form a prefabricated large-area wall element.
- the attachment lugs 3 and the attachment recesses 7 are each formed on a bar 9 and 9a, respectively, which is placed on the inside of the base plates 1.

Abstract
Description
Die Erfindung betrifft ein Wandelement zum Erstellen einer Wand, insbesondere einer großflächigen Schalungswand, aus einer Mehrzahl von Wandelementen, die mit ihren seitlichen Stoßrändern stumpf aneinanderstoßen, wobei das Wandelement eine im Einbauzustand vertikale Grundplatte mit geraden und zueinander parallelen seitlichen Stoßrändern an den Längsseiten der Grundplatte aufweist.The invention relates to a wall element for creating a wall, in particular a large-area formwork wall, from a plurality of wall elements which abut one another with their side abutting edges, the wall element having a vertical base plate in the installed state with straight and mutually parallel side abutting edges on the longitudinal sides of the base plate .
Erfindungsgemäße Wandelemente dienen insbesondere zum Erstellen von vorgefertigten großflächigen Schalungswänden. Die Erfindung kann jedoch auch für andersartige Wandelemente angewendet werden, mit denen beispielsweise Wände als Umbauten von Messeständen oder Raumteilerwände errichtet werden.Wall elements according to the invention are used in particular to create prefabricated large-area formwork walls. However, the invention can also be used for other types of wall elements with which, for example, walls are erected as conversions to exhibition stands or room partition walls.
Als derartige Wände vorgefertigte großflächige Schalungswände haben den Vorteil, daß möglichst wenige Stöße im Wandbereich vorhanden sind, da diese sowohl während der Montage als auch in der Behandlung für die fertige Wandoberfläche relativ aufwendig zu bearbeiten sind (Abschalungen und Abstützungen im Montagezustand für das Ausbetonieren der Wände, Bandagen und Spachtelung der Stöße für glatte Wandoberflächen). Derartige vorgefertigte großflächige Schalungswände sind derzeit nur aus Holzwerkstoffplatten bekannt, die jedoch beispielsweise aufgrund ihrer Brennbarkeit und Verrottbarkeit nicht immer den Anforderungen entsprechen, welche für Wandaußenflächen an einen Hochbau gestellt werden.Large-area formwork walls prefabricated as such walls have the advantage that there are as few joints as possible in the wall area, since these are relatively complex to work on both during assembly and in treatment for the finished wall surface (formwork and supports in the assembled state for concreting the walls , Bandages and filling of the joints for smooth wall surfaces). Such prefabricated large-area formwork walls are currently only known from wood-based panels, but due to their combustibility and rotability, for example, they do not always meet the requirements that are placed on a building structure for external wall surfaces.
Aus der GB-A-578 631 sind plattenförmige miteinander kombinierbare Wandelemente bekannt, die an den Längsseiten der Platten entweder einen seitlich mittig hervorstehenden einzelnen keilförmigen Einhängeansatz oder eine mittig in die Platte hineinreichende mit dem Einhängeansatz zusammenpassende Einhängeausnehmung aufweist. Der Einhängeansatz eines Wandelementes wird in die Ausnehmung eines anderen Wandelementes eingehängt, so daß die Stoßränder zweier nebeneinanderliegender Wandelemente aneinandergezogen werden.From GB-A-578 631, plate-shaped combinable wall elements are known which have either a single wedge-shaped hooking projection protruding laterally in the center on the longitudinal sides of the plates or a hooking recess which fits centrally with the hooking projection and extends into the plate. The attachment of one wall element is suspended in the recess of another wall element, so that the abutting edges of two adjacent wall elements are pulled together.
Das deutsche Patent No. 2 165 977 offenbart plattenförmige Wandelemente, die zum Ausbilden einer mit einem Füllstoff ausfüllbare Mantelbetonwand kombiniert werden können. Um die Wandelemente nebeneinanderzusetzen, weisen die Wandelemente an den seitlichen Stoßrändern rechteckige gestufte Aussparungen und in diese passende über die seitlichen Stößränder vorstehende Zapfen auf.German Patent No. 2 165 977 discloses plate-shaped wall elements which can be combined to form a shell concrete wall which can be filled with a filler. In order to place the wall elements next to one another, the wall elements have rectangular, stepped cutouts on the side abutting edges and pegs fitting into them that protrude beyond the side abutting edges.
Durch die Erfindung wird das Problem gelöst, wie Wandelemente der eingangs erwähnten Art so gestaltet werden können, daß sie in relativ kleinen Abmessungen auch aus anderem Material als Holzmaterial, insbesondere auch beispielsweise aus zementgebundenem Material, hergestellt und rasch zu einer großflächigen Wand aneinandergesetzt werden können.The invention solves the problem of how wall elements of the type mentioned at the outset can be designed such that they can also be produced in a relatively small size from material other than wood material, in particular also, for example, from cement-bound material, and can be quickly attached to one another to form a large-area wall.
Dies wird erfindungsgemäß mit einem Wandelement mit den Merkmalen gemäß Anspruch 1 erreicht.This is achieved according to the invention with a wall element with the features according to
Durch die erfindungsgemäße Gestaltung der Wandelemente kann in ein bereits aufgestelltes Wandelement ein zweites Wandelement beispielsweise mit einem Baukran verhältnismäßig einfach eingehängt werden, indem das zweite Wandelement mit seinem Einhängeansatz bis in Höhe der Einhängeausnehmung des ersten Doppelwandelementes angehoben und dann in die Einhängeausnehmung eingeführt wird, wonach es abgesenkt wird und dabei mit dem unteren Stirnrand seines Einhängeansatzes auf dem unteren Begrenzungsrand der Einhängeausnehmung in diese bis zum Aufeinandertreffen der einander benachbarten Stoßränder hineingleitet.Due to the design of the wall elements according to the invention, a second wall element, for example with a construction crane, can be hung relatively easily into a wall element that has already been set up, by raising the second wall element with its attachment attachment to the level of the insertion recess of the first double wall element and then inserting it into the insertion recess, after which it is inserted is lowered and thereby slides with the lower end edge of its attachment lug on the lower boundary edge of the insertion recess into it until the abutting edges meet.
Bei einem derartigen Doppelwandelement wird bei dem Zusammensetzen außerdem der Vorteil erreicht, daß das einzuhängende Doppelwandelement mit den ebenen Außenseiten der Einhängeansätze an den grundplattenseitigen ebenen Begrenzungsflächen der Einhängeausnehmungen auch quer zu den Grundplatten gleitend geführt wird, weil die Einhängeansätze aufgrund ihrer Anordnung an der Innenseite der Grundplatten zwischen diese eingreifen. Dadurch ist nach dem Einhängen des zweiten Doppelwandelementes zugleich eine formschlüssige Verbindung der Doppelwandelemente in horizontaler Richtung sowie in Richtung nach unten und quer zu der Ebene der Grundplatten gewährleistet.In the case of such a double wall element, the assembly also has the advantage that the double wall element to be hooked in with the flat outer sides of the Hook-in lugs on the base-side flat boundary surfaces of the hook-in recesses are also guided transversely to the base plates because the hook-in lugs engage between them due to their arrangement on the inside of the base plates. As a result, after the second double wall element has been hooked in, a positive connection of the double wall elements in the horizontal direction as well as in the direction downward and transversely to the plane of the base plates is ensured.
Durch die Anordnung der Einhängeansätze und der Einhängeausnehmungen an den Innenseiten der Grundplatten, jeweils von außen her gesehen hinter den Stoßrändern sind außerdem die Einhängeansätze und Einhängeausnehmungen nach dem Zusammenbauen der Doppelwandelemente nach außen hin abgedeckt, so daß von außen her nur die geraden Stoßfugen zwischen den aneinanderliegenden Stoßrändern sichtbar sind.Due to the arrangement of the suspension lugs and the suspension recesses on the inside of the base plates, each seen from the outside behind the abutting edges, the suspension lugs and suspension recesses are also covered outwards after the assembly of the double wall elements, so that from the outside only the straight butt joints between the adjacent ones Bump edges are visible.
Solche Doppelwandelemente dienen bevorzugt zum Errichten von großflächigen Verbundschalungswänden bei dem die Grundplatten z.B. über Abstandshalter fest miteinander verbunden sind. Erfindungsgemäße Doppelwandelemente bieten den weiteren Vorteil, daß sie aufgrund ihrer Standfestigkeit im wesentlichen ohne oder mit nur wenigen Abstützungs- und Abschalungshilfen zu einer großflächigen Doppelwand zusammengesetzt werden können.Such double wall elements are preferably used to erect large-area composite formwork walls in which the base plates e.g. are firmly connected to each other via spacers. Double wall elements according to the invention offer the further advantage that, due to their stability, they can be put together to form a large double wall, essentially without or with only a few support and formwork aids.
Der spitze Winkel, welchen die unteren Stirnränder der Einhängeansätze und die unteren Begrenzungsränder der Einhängeausnehmungen mit der Ebene des jeweils angrenzenden Stoßrandes einschließen, soll vorzugsweise nicht zu stumpf und nicht zu spitz sein. Als günstig hat sich ein Winkel im Bereich von 30 bis 60°, insbesondere 45° erwiesen. Allerdings können die Einhängeansätze und Einhängeausnehmungen auch andersartig ausgebildet sein, jedoch werden die Ausführungsformen mit schräg nach unten verlaufenden unteren Rändern bevorzugt.The acute angle, which the lower end edges of the attachment lugs and the lower boundary edges of the attachment recesses form with the plane of the adjacent abutting edge, should preferably not be too obtuse and not too acute. An angle in the range from 30 to 60 °, in particular 45 °, has proven to be favorable. However, the attachment lugs and attachment recesses can also be designed differently, but the embodiments with obliquely downward lower edges are preferred.
Im weiteren werden bevorzugte Ausgestaltungen der Erfindung für Doppelwandelemente beschrieben; die betreffenden Merkmale lassen sich jedoch entsprechend auch für erfindungsgemäße Einfachwandelemente anwenden.Preferred embodiments of the invention for double wall elements are described below; the characteristics in question can however also be used accordingly for single wall elements according to the invention.
Gemäß einer besonders bevorzugten Ausgestaltung der Erfindung sind die Einhängeeinsätze und die Einhängeausnehmungen gegen die Ebene des jeweils angrenzenden Stoßrandes seitlich versetzt, so daß an den den Einhängeansatz aufweisenden Längsseiten der Grundplatten ein Falz vorhanden ist, in den die betreffende, die Einhängeausnehmung aufweisende Längsseite der benachbarten Grundplatte eingreift, und die Stoßfuge von innen her vollflächig abgedeckt ist.According to a particularly preferred embodiment of the invention, the insertion inserts and the insertion recesses are laterally offset from the plane of the respectively adjacent abutting edge, so that a fold is present on the longitudinal sides of the base plates having the insertion attachment, into which the relevant longitudinal side of the adjacent base plate, which has the insertion recess engages, and the butt joint is completely covered from the inside.
Wenngleich die Einhängeansätze mit der Innenseite der Grundplatten bündig sein können, sind vorzugsweise die Einhängeansätze und die Einhängeausnehmungen begrenzende Plattenteile auf die ebenen Innenseiten der Grundplatten aufgesetzt.Although the suspension lugs can be flush with the inside of the base plates, the suspension lugs and plate parts delimiting the suspension recesses are preferably placed on the flat inner sides of the base plates.
Dabei können die Einhängeansätze und die die Einhängeausnehmungen begrenzenden Plattenteile als Einzelstücke auf die Innenseiten der Grundplatte aufgesetzt sein. Jedoch ist es auch möglich, daß die Einhängeansätze und/oder die Einhängeausnehmungen jeweils an einer Leiste ausgebildet sind, die über die Höhe der Grundplatten hin durchläuft. Dadurch kann eine einfache Herstellung des Einhängeansatzes und der Einhängeausnehmung verwirklicht werden, indem aus einer Platte eine langgestreckte Leiste ausgeschnitten wird, welche den Einhängeansatz aufweist und so das "Negativ" einer weiteren Leiste ausbildet, welche die Einhängeausnehmung aufweist. Auf diese Weise läßt sich eine sehr materialsparende Herstellung verwirklichen. Die beiden unterschiedlichen Leisten können dann an die jeweilige Längsseite der Grundplatten montiert werden. In beiden Fällen können durch den Zuschnitt der Grundplatten anfallender Verschnitt, der andernfalls entsorgt werden müßte, für die Ausbildung der Einhängeansätze und der die Einhängeausnehmungen begrenzenden Plattenteile verwendet werden.The attachment lugs and the plate parts delimiting the insertion recesses can be placed as individual pieces on the inside of the base plate. However, it is also possible that the suspension lugs and / or the suspension recesses are each formed on a bar that runs through the height of the base plates. As a result, a simple production of the attachment projection and the insertion recess can be achieved by cutting out an elongated strip from a plate, which has the insertion attachment and thus forms the "negative" of a further strip which has the insertion recess. In this way, a very material-saving production can be realized. The two different strips can then be mounted on the respective long side of the base plates. In both cases, by cutting the base plates, any waste that would otherwise have to be disposed of can be used for the formation of the suspension lugs and the plate parts delimiting the suspension recesses.
Im Prinzip kann je nach der Höhe der Grundplatten bereits ein Einhängeansatz bzw. eine Einhängeausnehmung an den Längsseiten der Grundplatten genügen. Vorzugsweise jedoch weist jede Längsseite der Grundplatten eine Mehrzahl von Einhängeansätzen bzw. Einhängeausnehmungen auf. Dadurch läßt sich eine stabilere Verbindung zwischen den einander benachbarten Doppelwandelementen erzielen. Gemäß einer vorteilhaften Weiterbildung der Erfindung kann dabei die Verteilungsdichte von Einhängeansätzen bzw. Einhängeausnehmungen bei den jeweiligen Längsseiten im unteren Bereich des Doppelwandelements größer sein als in dessen oberem Bereich. Dadurch ist eine höhere Verbindungsfestigkeit im unteren Bereich gewährleistet, in welchem in der Anwendungsform der Doppelwandelemente als Schalungsplattenelemente eine höhere Belastung aufgrund des Druckes des zwischen die Grundplatten gegossenen flüssigen Betons vorhanden ist.In principle, depending on the height of the base plates, a hooking attachment or a hooking recess on the long sides of the base plates can suffice. However, each longitudinal side of the base plates preferably has a plurality of attachment lugs or attachment recesses. This makes it possible to achieve a more stable connection between the adjacent double wall elements. According to an advantageous development of the invention, the distribution density of suspension attachments or suspension recesses on the respective longitudinal sides can be greater in the lower region of the double wall element than in the upper region thereof. This ensures a higher connection strength in the lower area, in which, in the application form of the double-wall elements as formwork panel elements, there is a higher load due to the pressure of the liquid concrete poured between the base plates.
In dem Fall, daß die Einhängeansätze jeweils durch einzelne auf die Grundplatte aufgesetzte Platten ausgebildet sind, können in die Lücken zwischen die Einhängeansätze Zwischenstücke eingebaut sein, wodurch sich eine stabilere Konstruktion und eine bessere Lagegenauigkeit der Einhängeansätze ergibt und außerdem der Stoßrand auch im Bereich zwischen aufeinanderfolgenden Einhängeansätzen durch über den Stoßrand vorstehende Zwischenstücke abgedeckt werden kann. Eine solche Abdeckung kann auch mit der oben erwähnten, die Einhängeansätze tragenden Leiste erreicht werden, wenn diese über den Stoßrand seitlich hinausragt.In the event that the suspension lugs are each formed by individual plates placed on the base plate, intermediate pieces can be built into the gaps between the suspension lugs, which results in a more stable construction and a better positional accuracy of the suspension lugs and also the joint edge in the area between successive ones Attachment approaches can be covered by intermediate pieces protruding over the edge of the joint. Such a cover can also be achieved with the above-mentioned bar, which carries the attachment lugs, if it extends laterally beyond the edge of the joint.
Die Einhängeausnehmungen können, abgesehen von dem erforderlichen Spiel komplementär zu den Einhängeansätzen ausgebildet sein. Vorgezogen wird jedoch, daß die parallel zu den Stoßrändern gemessene Höhe der Einhängeausnehmungen größer als die betreffende Höhe der Einhängeansätze ist. Hierdurch wird die Montage der Doppelwandelemente begünstigt.The suspension recesses can, apart from the required play, be complementary to the suspension lugs. However, it is preferred that the height of the mounting recesses measured parallel to the abutting edges is greater than the relevant height of the mounting lugs. This favors the assembly of the double wall elements.
Vorteilhaft ist das Doppelwandelement aus einem im wesentlichen zementgebundenen Material, aus Rigips oder aus Holz hergestellt. Die Wahl des Werkstoffs erfolgt passend zu der jeweiligen Anwendung, d.h. der Anwendung als Stellwand oder dergl. oder für eine verlorene Schalung.The double wall element consisting of one is advantageous cement-bound material, made of plasterboard or wood. The choice of material is made according to the respective application, ie the use as a partition or the like or for a lost formwork.
Wenngleich die Doppelwandelemente auf der Baustelle zu der Doppelwand zusammengesetzt werden können, wird es erfindungsgemäß bevorzugt, sie bereits im Werk zu einer vorgefertigten großflächigen Doppelwand zusammenzusetzen und miteinander zu verbinden, bevorzugt durch Verkleben, aber auch mit Hilfe anderer Verbindungsarten wie Verschrauben, Vernieten oder Verdübeln und dergl. Die Erfindung bezieht sich daher auch auf eine derartige vorgefertigte Doppelwand. Hierbei können auch Paßstücke wie auch sämtliche erforderlichen Öffnungen, wie Türen, Fenster, Durchbrüche und dergl. bereits im Werk vorgesehen werden.Although the double-wall elements can be assembled on site to form the double wall, it is preferred according to the invention to assemble and connect them together in the factory to form a prefabricated large-area double wall, preferably by gluing, but also with the aid of other types of connection such as screwing, riveting or dowelling and The like. The invention therefore also relates to such a prefabricated double wall. Here, fittings as well as all necessary openings such as doors, windows, openings and the like can already be provided in the factory.

- 3 shows a side view of two mutually suspended base plates of two double-wall elements and a third double-wall element shortly before hanging, seen on the inside of the base plates;
- 4 shows a section along the section line AB in FIG. 3; and
- Fig. 5 is a side view of a base plate, viewed from the inside, ie from the space between the base plates.
Wie aus Fig. 1a und 1b ersichtlich ist, weist das Doppelwandelement zwei Grundplatten 1 auf, welche parallel zueinander verlaufen. Die beiden Grundplatten 1 sind in der gezeigten Ausführungsform mittels Abstandshaltern 2 miteinander verbunden und werden von diesen fest in ihrer parallelen Lage gehalten. Es ist aber auch möglich, die Grundplatten 1 auf andere Weise fest zusammenzuhalten, z.B. mit Hilfe von Schrauben und Hülsen.As can be seen from FIGS. 1a and 1b, the double wall element has two
Von den beiden Längsseiten der Grundplatten 1 werden seitliche Stoßränder 15, 16 gebildet, die nach dem Zusammensetzen der Doppelwandelemente stumpf auf den Stoßrändern der Grundplatten der jeweils benachbarten Doppelwandelemente aufliegen.Lateral
Hinter dem einen Stoßrand 15 sind entsprechend Fig. la und 1b auf die einander zugewandten Innenseiten der Grundplatten 1 über den Stoßrand 15 nach außen hinausragende plattenförmige Einhängeansätze 3 aufgesetzt, deren Plattenebene daher parallel zu den Grundplatten verläuft. Diese Einhängeansätze 3 können mit der Grundplatte 1 verklebt, verschraubt oder auf sonstige Weise verbunden sein. Der über den Stoßrand 15 nach außen hinausragende untere Stirnrand 6 der plattenförmigen Einhängeansätze 3 verläuft von der Ebene des Stoßrandes 15 aus in einem Winkel, der im Ausführungsbeispiel 45° beträgt, schräg nach unten. Während nach Fig. la die Einhängeansätze 3 als Einzelplattenstücke ausgeführt sind, zwischen denen ebenfalls mit der Grundplatte 1 verbundene Zwischenstücke 4 eingesetzt sind, sind die Einhängeansätze 3 nach Fig. lb an einer ihnen gemeinsamen Leiste 9 ausgeführt.According to FIGS. 1 a and 1 b, plate-
Wie aus den Fig. 2a und 2b ebenfalls in perspektivischer Darstellung ersichtlich, sind hinter dem anderen Stoßrand 16 Einhängeausnehmungen 7 ausgebildet, die jeweils nach oben und nach unten von zwei Plattenteilen 8 begrenzt sind. Der untere Begrenzungsrand 10 der Einhängeausnehmungen 7 verläuft in dem gleichen Winkel wie der untere Stirnrand 6 der Einhängeansätze 3 zur Mitte der Grundplatte 1 hin schräg nach unten. Die Plattenteile 8 sind ebenso wie die Einhängeansätze 3 auf die Grundplatte 1 aufgesetzt und mit dieser verklebt, verschraubt oder auf sonstige Weise verbunden. Bei der Ausführungsform aus Fig. 2a sind die Plattenteile 8 als Einzelstücke ausgeführt, wohingegen sie bei der Ausführungsform aus Fig. 2b an einer ihnen gemeinsamen Leiste 9a ausgebildet sind.As can also be seen in FIGS. 2a and 2b in a perspective view, 16
Die Doppelwandelemente können daher derart zusammengesetzt werden, daß die Einhängeansätze 3 des einen Doppelwandelementes in die Einhängeausnehmungen 7 des anderen Doppelwandelementes eingreifen, wobei die Stoßränder 15, 16 der Doppelwandelemente aufeinanderliegen. Daher sind die zusammengesetzten Doppelwandelemente fest miteinander verzahnt.The double wall elements can therefore be put together in such a way that the attachment lugs 3 of one double wall element engage in the suspension recesses 7 of the other double wall element, the abutting
Die Lücken zwischen den rhombischen Einhängeansätzen 3 sind auf der Innenseite der Grundplatte 1 durch ebenfalls plattenförmige rhombische Zwischenstücke 4 ausgefüllt, die mit ihrem äußeren Seitenrand etwas über den Stoßrand 15 hinausragen, so daß von ihrem vorstehenden Seitenrand und den Einhängeansätzen 3 einerseits und dem Stoßrand 15 andererseits ein Falz 5 begrenzt wird. Entsprechend sind die ebenfalls rhombischen Plattenteile 8, zwischen denen die Einhängeausnehmungen 7 gebildet werden, gegen den Stoßrand 16 versetzt, so daß beim Zusammensetzen zweier Doppelwandelemente die den Stoßrand 16 bildende Längsseite der Grundplatte 1 des einen Doppelwandelementes in den Falz 5 der betreffenden Grundplatte 1 des anderen Doppelwandelementes eingreifen kann und daher die Stoßfuge zwischen den Stoßrändern 15 und 16 von innen her abgedeckt ist. Eine entsprechende Abdeckung erfolgt bei der Ausführungsform aus Fig. 1b mit Hilfe der mit ihrem durchlaufenden Teil über den Stoßrand 15 vorstehenden Leiste 9.The gaps between the rhombic suspension lugs 3 are filled on the inside of the
Wie links aus Fig. 3 ersichtlich ist, haben die Einhängeausnehmungen 7 eine größere lichte Höhe als die Einhängeansätze 3, wodurch sich die Einhängeansätze 3 leicht in die Einhängeausnehmungen 7 seitlich einführen lassen. Wie in der Fig 3 ersichtlich ist, wird ein Doppelwandelement 11 soeben in ein Doppelwandelement 12 eingepaßt, welches seinerseits bereits fest in ein Doppelwandelement 13 eingepaßt ist.As can be seen on the left in FIG. 3, the hanging
Beim Einpassen des Doppelwandelements 11 in das Doppelwandelement 12 wird das Doppelwandelement 11 z.B. mit Hilfe eines Baukrans angehoben und mit den Einhängeansätzen 3 seitlich in die Einhängeausnehmungen 7 des anderen Doppelwandelementes 12 eingeführt und danach abgesenkt, so daß die Einhängeansätze 3 auf den unteren Begrenzungsrändern 10 der Einhängeausnehmungen 7 nach unten und in diese hineingleiten, bis die Stoßränder 15 und 16 der Grundplatten 1 der Doppelwandelemente 11, 12 aufeinandertreffen. In dieser Position sind die Doppelwandelemente formschlüssig miteinander verzahnt, wie links aus Fig. 3 für die Doppelwandelemente 12 und 13 gezeigt ist. Zusätzlich können die einzelnen Doppelwandelemente miteinander verklebt oder auf sonstige Weise aneinander fixiert werden, insbesondere zu einem vorgefertigten großflächigen Wandelement zusammengebaut werden.When fitting the
Bei der Ausführungsform aus den Fig. 3 und 4 sind im übrigen die Einhängeansätze 3 und die Einhängeausnehmungen 7 jeweils an einer Leiste 9 bzw. 9a ausgebildet, die auf die Innenseite der Grundplatten 1 aufgesetzt ist.In the embodiment from FIGS. 3 and 4, the attachment lugs 3 and the attachment recesses 7 are each formed on a
