Bei der Erfindung handelt es sich um ein plattenförmiges Wandelement für nach dem Baukastenprinzip zu erstellende Gebäude unter Verwendung einer wenigstens ein Wandblatt tragenden, rechteckigen Einfassung aus Stahl, wobei das sandwichartig aufgebaute Wandblatt an seinen vertikalen Längsseiten mit Bohlen aus Holz bewehrt ist und eine aus einem wärmedämmenden Material bestehende Kernschicht aufweist, die an ihren beiden Seiten je eine Deckschicht trägt, welche die Bohlen übergreift, und zur Bildung der Einfassung ein umlaufender Rahmen dient und Verbindungsmittel vorgesehen sind, welche Rahmen und Wandblatt verbinden.The invention is a plate-shaped wall element for buildings to be built according to the modular principle using a rectangular frame made of steel carrying at least one wall sheet, the sandwich-like wall sheet being reinforced with planks of wood on its vertical long sides and one made of a heat-insulating one Material existing core layer, which carries on both sides of a cover layer, which overlaps the planks, and a peripheral frame is used to form the enclosure and connecting means are provided which connect the frame and wall panel.

Das vorgeschlagene Wandelement findet insbesondere Anwendung bei der Erstellung von fabrikmäßig vorgefertigten Industriehallen in Fertigbauweise.The proposed wall element is used in particular in the production of prefabricated prefabricated industrial halls.

Plattenförmige Wandelemente mit einer ein Wandblatt tragenden Einfassung aus Stahl sind in verschiedenen Ausführungsformen bekannt. Bei einem Teil davon entspricht die Wärmedämmungnicht den heutigen hohen Erfordernissen die meisten besitzen keine ausreichenden Fähigkeiten zum Tragen der Dachkonstruktion, wieder andere sind nur recht umständlich, fertigbar oder müssen zeitaufwendig montiert werden, und viele sind aufgrund ihres Aufbaues einfachen statischen Berechnungsmethoden nicht zugängich (DE-U 7 826 852, DE-A 2 335 863, DE-A 23 51 063, DE-A 28 00 769, EP-A 0 083 276, EP-A 0 096 118, DE-A 1 957255).Plate-shaped wall elements with a steel frame supporting a wall sheet are known in various embodiments. In some of them, the thermal insulation does not meet today's high requirements, most of them do not have sufficient abilities to support the roof structure, others are only very cumbersome, can be manufactured or require time-consuming assembly, and many are not accessible due to their structure, simple static calculation methods (DE- U 7 826 852, DE-A 2 335 863, DE-A 23 51 063, DE-A 28 00 769, EP-A 0 083 276, EP-A 0 096 118, DE-A 1 957255).

Es ist zwar ein zur Einstellung von Gebäuden in Leichtbauweise vorgesehenes, plattenförmiges Bauteil bekannt, welches ein sandwichartig aufgebautes, seitlich mit Holzbohlen bewehrtes Wandblatt aufweist, das mit einer rechteckigen Einfassung aus Winkelprofilen versehen ist. Das Wandblatt weist zwei Deckschichten auf, deren Zwischenraum zur Wärmedämmung mit Holzfasern gefühllt ist. Die Festigkeit und die Tragfähigkeit dieses Bauelementes ist jedoch begrenzt, sodaß es nur zur Anwendung beim Bau von Baracken, Garagen o.ä. geeignet ist (US-A-2 031 568).There is known a plate-shaped component intended for setting buildings of lightweight construction, which has a sandwich-like wall sheet reinforced with wooden planks on the side, which is provided with a rectangular border made of angle profiles. The wall sheet has two cover layers, the space between which is filled with wood fibers for thermal insulation. The strength and load-bearing capacity of this component is limited, however, so that it can only be used in the construction of barracks, garages or the like. is suitable (US-A-2 031 568).

Die Aufgabe der Erfindung besteht in der Konzeption eines plattenförmigen, großflächigen Wandelementes für Gebäude, welches sich zugleich durch hervorragende Wärmedämmeigenschaften, hohe Tragfähigkeit zwecks Auflage des Daches, rationelle Herstellbarkeit und schnelle Montage, einfache Demontierbarkeit z.B. bei Beschädigungen und leichte statische Berechenbarkeit auszeichnet.The object of the invention is to design a plate-shaped, large-area wall element for buildings, which is also characterized by excellent thermal insulation properties, high load-bearing capacity for the purpose of supporting the roof, rational manufacturability and quick assembly, easy dismantling e.g. in the event of damage and easy static predictability.

Zur Lösung der gestellten viefältigen Aufgabe wird von einem plattenförmigen Wandelement für nach dem Baukastenprinzip zu erstellende Gebäude unter Verwendung einer wenigstens ein Wandblatt tragenden, rechteckigen Einfassung aus Stahl wie eingangs beschrieben ausgegangen und gelöst wird diese Aufgabe dadurch, daß die Kernschicht aus Hartschaumkunststoff besteht, die Deckschichten aus Stahlblech gefertigt sind, die Deckschichten mit der Kernschicht schubfest haftverbunden sind, die Einfassung aus zwei gleichgroßen, biegesteifen Rahmen aus U-Profil-Stählen besteht, welche mit ihren Rücken gegeneinander gerichtet sind und mit den Rücken auf dem Wandblatt liegen und als Verbindungsmittel Muttern tragende Gewindebolzen dienen.To solve the manifold problem, a plate-shaped wall element for buildings to be built according to the modular principle using a rectangular frame made of steel carrying at least one wall sheet, as described in the introduction, is assumed and this object is achieved in that the core layer consists of rigid foam plastic, the cover layers are made of sheet steel, the cover layers are bonded to the core layer in a shear-resistant manner, the edging consists of two equally large, rigid frames made of U-profile steels, which are directed towards each other with their backs and lie on the wall sheet with their backs and bear nuts as a connecting means Serve threaded bolts.

Die geforderte Wärmedämmung wird durch die aus Hartschaumkunststoff bestehende Kernschicht des Wandblattes und demzufolge der thermischen Trennung von Außen- und Innenseite, die statische Festigkeit insbesondere durch die schubfeste Verbindung der Schichten des Wandblattes in Kombination mit den U-Profil- Stählen der beiden biegesteifen Rahmen, die einfache Herstellbarkeit sowie die schnelle Montage und Demontage durch den Aufbau aus nur drei Elementen und die leichte Berechenbarket durch die Ausbildung der beiden gleichen Rahmen erreich. Das Wandelement wirkt mit seinen fest miteinander verbundenen Bestandteilen als starre Scheibe, sodaß Gebäude, die aus einem solchen Wandelement erstellt werden, keine weiteren Aussteifungs- und Stabilisierungselemente in der Wandebene benötigen.The required thermal insulation is due to the core layer of the wall sheet made of rigid foam plastic and consequently the thermal separation of the outside and inside, the static strength in particular through the shear-resistant connection of the layers of the wall sheet in combination with the U-profile steels of the two rigid frames Easy to manufacture as well as the quick assembly and disassembly through the construction of only three elements and the easy predictability by the formation of the two same frames. The wall element with its firmly connected components acts as a rigid disc, so that buildings that are created from such a wall element do not require any further stiffening and stabilizing elements in the wall plane.

Zum Zwecke der Erleichterung bei der Herstellung besteht das Wandblatt aus zwei oder mehreren Einzelblättern, welche durch Nuten und Federn verbunden sind und stumpf aneinander stoßen.For the purpose of making it easier to manufacture, the wall sheet consists of two or more single sheets which are connected by grooves and tongues and butt butt.

Zwecks Erhöhung der Biegesteifigkeit der beiden Rahmen tragen diese an iheren Ecken Aussteifungen; als solche dienen zweckmäßig Dreieckbleche, welche in die Ecken eingeschweißt sind.In order to increase the bending stiffness of the two frames, they are braced at their corners; triangular plates which are welded into the corners serve expediently as such.

Eine wichtige erfinderische Ausgestaltung der Erfindung besteht in einem am Rand des Wandelementes befestigten, prismatisch ausgebildeten Verstärkungselement, dessen Länge mit dem Rand übereinstimmt und dessen Dicke wenigstens derjenigen des Wandelementes entspricht. Mit Hilfe dieses einfachen zusätzlichen Bauelementes kann die Tragfähigkeit des Wandelementes mit geringem Aufwand entscheidend vergrößert werden. Dieses Verstärkungselement wird zwischen zwei benachbarten Wandelementen angeordnet und an den Rändern dieser beiden befestigt. Zusammen mit den in gleicher Richtung sich erstreckenden vier U-Profil-Stählen der beiden Rahmen und der beiden Bohlen aus Holz, mit welchen das Wandblatt bewehrt ist, wird mit geringem Aufwand ein ungewöhnlich und unerwartet widerstandsfähiges Tragelement gebildet.An important inventive embodiment of the invention consists in a prismatic reinforcement element attached to the edge of the wall element, the length of which corresponds to the edge and the thickness of which corresponds at least to that of the wall element. With the help of this simple additional component, the load-bearing capacity of the wall element can be significantly increased with little effort. This reinforcing element is arranged between two adjacent wall elements and attached to the edges of these two. Together with the four U-profile steels, which extend in the same direction, of the two frames and the two wooden planks with which the wall panel is reinforced, an unusually and unexpectedly resistant support element is formed with little effort.

Im einfachsten Falle ist das Verstärkungselement ein Balken aus Holz; das Verstärkungselement kann auch eine wasserfest verleimte Schichtholz-Planke, eine glas- oder kohlefaserverstärkte Kunststoffleiste oder auch ein Flachstahlstück sein.In the simplest case, the reinforcement element is a wooden beam; the reinforcing element can also be a waterproof glued plywood plank, a glass or carbon fiber reinforced plastic strip or a flat steel piece.

Zweckmäßig ist das Verstärkungselement unter Verwendung von Befestigungsmitteln in Gestalt von Gewindebolzen an den beiden Rahmen befestigt.The reinforcing element is expediently fastened to the two frames using fastening means in the form of threaded bolts.

Das in den Zeichnungen dargestellte, plattenförmige Wandelement besteht aus einem zweiteiligen Wandblatt 1, zwei Rahmen 2 und 3 sowie Verbindungsmitteln 4 und 5. Das Wandelement kann mit Tür- und Fensteröffnungen (nicht dargestellt) versehen sein.The plate-shaped wall element shown in the drawings consists of a two-part wall sheet 1, two frames 2 and 3 and connecting means 4 and 5. The wall element can be provided with door and window openings (not shown).

Das rechteckige Wandblatt 1 ist sandwichartig aufgebaut und besteht aus einer Kernschicht 6 sowie zwei-Dechschichten 7 und 8. Die beiden Deckschichten 7 und 8 sind mit der Kernschicht 6 schubfest haftverbunden, z.B. durch eine Klebverbindung.The rectangular wall sheet 1 is constructed like a sandwich and consists of a core layer 6 and two double layers 7 and 8. The two cover layers 7 and 8 are bonded to the core layer 6 in a shear-resistant manner, e.g. through an adhesive connection.

Die Kernschicht 6 besteht aus einem wärmedämmenden, festen Hartschaumkunstoff. Bei Herstellung das Wandblattes 1 mittels einer Form, in welche die beiden Deckschichten 7 und 8 eingelegt sind und dann das Material der Kernschicht 6 in flüssiger Form eingebracht wird, bildet dieses bei seiner Erstarrung die schubfeste Haftverbindung, und eine gesonderte Klebeverbindung entfällt.The core layer 6 consists of a heat-insulating, rigid foam plastic. When the wall sheet 1 is produced by means of a mold in which the two cover layers 7 and 8 are inserted and then the material of the core layer 6 is introduced in liquid form, this forms the shear-resistant adhesive connection when it solidifies, and a separate adhesive connection is not required.

Die beiden Deckschichten 7 und 8 aus Stahlblech gefertigt. Hierbei können ebene Blechplatten oder Bleche mit einem niederen U- oder Trapez-Profil, die eine höhere Steifigkeit besitzen, verwendet werden.The two cover layers 7 and 8 made of sheet steel. Flat sheet metal plates or sheets with a lower U or trapezoidal profile, which have a higher rigidity, can be used.

Das Wandblatt 1 besteht aus zwei länglichrechteckigen Einzelblättern 9 und 10, welche mit ihren Längskanten 11 in der Mitte des Wandelementes stumpf aneinander stoßen. Die beiden Einzelblätter 9 und 10 tragen entlang ihren Längskanten 11 Nuten 12, in welche eine die Verbindung der beiden Einzelblätter 9 und 10 bewirkende 13 eingelegt ist.The wall sheet 1 consists of two elongated rectangular single sheets 9 and 10, which abut each other with their longitudinal edges 11 in the middle of the wall element. The two single sheets 9 and 10 have 11 grooves 12 along their longitudinal edges, into which a connection 13 which connects the two single sheets 9 and 10 is inserted.

Jedes Einzelblatt 9 bzw 10 ist an seiner äußeren Längsseite-vgl. Figure 3-mit einer Bohle 14 aus Holz bewehrt. Diese Bohle 14 erstreckt sich über die ganze Länge des Einzelblattes 9 bzw. 10, und sie besitzt einen rechteckigen Querschnitt. Die beiden Deckschichten 7 und 8 übergreifen die Bohle 14 und deren Kanten stehen mit der Außenseite der Bohle 14 bündig; die Deckschichten 7 und 8 können an der Bohle 14 bzw. durch Schrauben o.ä. befestigt sein.Each single sheet 9 or 10 is on its outer longitudinal side - cf. Figure 3-reinforced with a wooden plank 14. This screed 14 extends over the entire length of the single sheet 9 or 10, and it has a rectangular cross section. The two cover layers 7 and 8 overlap the screed 14 and their edges are flush with the outside of the screed 14; the cover layers 7 and 8 can be attached to the screed 14 or by screws or the like. be attached.

Die beiden Rahmen 2 und 3 bilden zusammen eine das Wandblatt 1 tragende, aus Stahl bestehende Einfassung. Diese beiden umlaufenden Rahmen 2 und 3 sind hinsichtlich ihrer äußeren Abmessungen gleich groß und biegesteif ausgebildet und bestehen aus Profilstählen. Zwischen diese Rahmen 2 und 3 ist das ein- oder mehrteilige Wandblatt 1 (im dargestellten Falle: die beiden Einzelblätter 9 und 10) eingesetzt. Wird das Wandelelement zur Auflage eines Daches benutzt, dann kann der äußere Rahmen 3 etwas niederer ausgebildet sein als der innere Rahmen 2.The two frames 2 and 3 together form a wall sheet 1 supporting, made of steel. These two circumferential frames 2 and 3 are of the same size and rigid in terms of their outer dimensions and consist of section steels. Between these frames 2 and 3, the one-part or multi-part wall sheet 1 (in the case shown: the two single sheets 9 and 10) is inserted. If the converting element is used to support a roof, then the outer frame 3 can be designed somewhat lower than the inner frame 2.

Die beiden Rahmen 2 und 3 bestehen aus U-Profil-Stählen welche an ihren Ecken auf Gehrung abgeschnitten und dort mittels Schweißnähten 15 miteinander verbunden sind.The two frames 2 and 3 are made of U-section steels which are mitred at their corners and connected there by means of weld seams 15.

Die U-Profil-Stähle der beiden Rahmen 2 und 3 sind mit ihren Rücken 16 gegeneinander gerichtet und liegen mit diesen Rücken 16 auf dem Wandblatt 1 auf, vgl. insbesondere Figur 2.The U-profile steels of the two frames 2 and 3 are directed towards one another with their backs 16 and lie with these backs 16 on the wall sheet 1, cf. in particular Figure 2.

Zur Erstellung der Wand eines Gebäudes werden mehrere der vorgeschlagenen plattenförmigen Wandelemente neben- und auch übereinanderer angeordnet und stumpf aneinander stoßen, so daß die Rücken, der U-Profil-Stähle dicht nebeneinander liegen und fest miteinander verbunden werden können. Zu diesem Zweck weisen die Rücken benachbarter U-Profil-Stähle Reihen von miteinander fluchtenden Löchern 17 für entsprechende, die Rücken durchsetzende Verbindungsschrauben auf. Durch die Verbindung der jeweils benachbarten Profil-Stähle zweier Wandelemente entsteht ein hoch belastbares, tragfähiges Bauelement, z.B. eine Stütze zur Auflage des Daches, deren Querschnitt in Figur 3, ganz rechts mit Strichlinien angedeutet ist. Entsprechend lassen sich Riegl bilden.To create the wall of a building, several of the proposed plate-shaped wall elements are arranged side by side and also one above the other and butt against one another, so that the backs of the U-profile steels lie close together and can be firmly connected to one another. For this purpose, the backs of adjacent U-profile steels have rows of holes 17 aligned with one another for corresponding connecting screws passing through the backs. By connecting the adjacent section steels of two wall elements, a highly resilient, load-bearing component is created, e.g. a support for supporting the roof, the cross section of which is indicated on the far right in FIG. 3 with dashed lines. Riegl can be formed accordingly.

Der untere horizontale Schenkel 18 des äußeren Rahmens 3 besteht-vgl. insbesondere Figur 2-aus einem Z-Profil-Stahl.The lower horizontal leg 18 of the outer frame 3 consists - see. in particular Figure 2 - made of a Z-profile steel.

Zwecks Erhöhung ihrer Biegesteifigkeit tragen die beiden rahmen 2 und 3 an ihren Ecken Aussteigungen 19 in Gestalt von Dreiecksblechen, welche in die Ecken eingeschweißt sind.In order to increase their bending stiffness, the two frames 2 and 3 have exits 19 at their corners in the form of triangular sheets which are welded into the corners.

Die Verbindungsmittel 4 bzw. 5 sind zur festen Verbindung der beiden Rahmen 2 und 3 mit dem Wandblatt 1 bzw. der beiden Einzelblätter 9 und 10 vorgesehen. Als Verbindungsmittel 4 dienen Gewindebolzen, welche beiderseits Muttern 20 tragen und das Wandblatt 1 sowie die beiden Profil-Stähle der Rahmen 2 und 3 durchsetzen. Durch entsprechendes Anziehen der Muttern 20 wird das Wandblatt 1 zwischen dem inneren und dem äußeren Rahmen 2 bzw. 3 festgepreßt. Um hierbei Beschädigungen des Wandblattes 1 zu vermeiden, oder die übertragene Schubkraft zu erhöhen, sind in letzteres Stahlhülsen 21 zur Aufnahme der Gewindebolzen eingelassen. An Stelle der Gewindebolzen können als Verbindungsmittel 5 auch geeignete Stahlschrauben verwendet werden, welche die Profil-Stähle durchsetzen und in das Wandblatt 1 eingedreht sind.The connecting means 4 and 5 are provided for the firm connection of the two frames 2 and 3 to the wall sheet 1 and the two individual sheets 9 and 10. The connecting means 4 are threaded bolts which carry nuts 20 on both sides and penetrate the wall panel 1 and the two profile steels of the frames 2 and 3. By appropriately tightening the nuts 20, the wall sheet 1 is pressed between the inner and outer frames 2 and 3, respectively. In order to avoid damage to the wall sheet 1 or to increase the transmitted thrust, steel sleeves 21 are inserted in the latter for receiving the threaded bolts. Instead of the threaded bolts, suitable steel screws can also be used as the connecting means 5, which penetrate the profile steels and are screwed into the wall sheet 1.

Zwecks Bildung hoch belastbarer Wandelemente ist (vgl. Figuren 1 und 3) am vertikalen Rand 22 des Wandelementes 1 ein prismatisch ausgebildetes Verstärkungselement 23 befestigt. Die Länge diese Verstärkungselementes 23 stimmt mit dem Rand 22 bzw. der Höhe des Wandelementes 1 überein und seine Dicke 24 entspricht derjenigen des Wandelementes 1.A prismatic reinforcing element 23 is attached to the vertical edge 22 of the wall element 1 in order to form wall elements which can withstand high loads (cf. FIGS. 1 and 3). The length of this reinforcing element 23 corresponds to the edge 22 or the height of the wall element 1 and its thickness 24 corresponds to that of the wall element 1.

Das Verstärkungselement 23 ist ein Balken aus Holz (Figur 3), es kann aber auch durch eine wasserfest verleimte Schichtholz-Planke, durch eine glas- oder kohlefaserverstärkte Kunststoffleiste oder ein Flachstahlstück gebildet sein.The reinforcing element 23 is a bar made of wood (FIG. 3), but it can also be formed by a waterproof glued plywood plank, by a glass or carbon fiber reinforced plastic strip or a flat steel piece.

Das Verstärkungselement 23 trägt zwei seinem Schutz dienende Längsleisten 25, beispielsweise aus Metall oder Kunststoff, welche einen U-förmigen Querschnitt aufweisen.The reinforcing element 23 carries two longitudinal strips 25 serving to protect it, for example made of metal or plastic, which have a U-shaped cross section.

Das Verstärkungselement 23 ist unter Verwendung von die Löcher 17 durchsetzenden Befestigungsmitteln 26-beispielsweise mit Muttern versehen Gewindeschrauben-an den beiden Rahmen 2 und 3 zweier benachbarter Wandelement 1 eingeschraubt, wie das in Figur 3 mit Strichlinien links angedeutet ist.The reinforcing element 23 is screwed onto the two frames 2 and 3 of two adjacent wall elements 1 using fastening means 26 which penetrate the holes 17, for example provided with nuts, as is indicated in FIG. 3 by dashed lines on the left.

Das Verstärkungselement 23, welches-siehe insbesondere Figur 4-nach seiner Befestigung an den Wandelementen 1 zusammen mit den benachbarten Profil-Stählen der Rahmen 2 und 3 sowie den Bohlen 14 (und gegebenenfalls der Längsleisten 25) ein überraschend hoch belastbares, tragfahiges Bauelement bildet, kann nicht nur am vertikalen Rand 22, sondern auch am horizontalen Rand des Wandlerelementes 1 befestigt sein. Der Querschnitt dieses Bauelementes ist in Figur 4 erkennbar.The reinforcing element 23, which - see in particular FIG. 4 - forms a surprisingly highly resilient, load-bearing component after it is fastened to the wall elements 1 together with the adjacent section steels of the frames 2 and 3 and the planks 14 (and, if appropriate, the longitudinal strips 25) can be attached not only to the vertical edge 22, but also to the horizontal edge of the transducer element 1. The cross section of this component can be seen in Figure 4.
