Die Erfindung betrifft ein trägerartiges, aus Einzelteilen zusammengesetztes Bauelement, mit einem Gurt und zwei Stegen sowie ein daraus gebildetes Konstruktionselement. Weiters betrifft die Erfindung ein Verfahren und eine Vorrichtung zur Herstellung dieses Bauelements.The invention relates to a carrier-like, composed of individual components, with a belt and two webs and a structural element formed therefrom. Furthermore, the invention relates to a method and an apparatus for producing this device.
Bauelemente dieser Art, die im Querschnitt mit dem Gurt und den zwei Stegen ein Dreieck bilden, sind bekannt. Bauelemente dieser Art werden als Strang-Press-Profil hergestellt. Die Erfindung stellt sich die Aufgabe, ein Bauelement dieser Art zu schaffen, das aus Einzelteilen zusammengesetzt ist, sodass das Bauelement gegebenenfalls aus unterschiedlichen Werkstoffen bzw. aus unterschiedlich behandelten, d.h. unterschiedlich vorgefertigten Werkstoffen, für den Gurt und die Stege gebildet werden kann. Das Bauelement soll weiters eine hohe Tragfähigkeit und eine hohe Torsionssteifigkeit aufweisen sowie insbesondere auf einfache Art und Weise herstellbar sein.Components of this type, which form a triangle in cross-section with the belt and the two webs, are known. Components of this type are manufactured as a strand-press profile. The invention has as its object to provide a component of this kind, which is composed of individual parts, so that the component optionally made of different materials or from differently treated, i. different prefabricated materials for the belt and the webs can be formed. The device should further have a high load capacity and high torsional stiffness and in particular be easy to produce.
Diese Aufgabe wird erfindungsgemäß dadurch, gelöst, dass ein Gurt an seinen beiden Längsseiten jeweils mit einem Steg versehen ist, wobei jeder Steg an einer Längsseitenwand des Gurtes befestigt ist, vorzugsweise mittels Klebstoff, und dass die dem Gurt abgewandten Endbereiche der Stege mit den zueinander gerichteten Flächen miteinander flächig verbunden sind, vorzugsweise mittels Klebstoff, wobei die Stege jeweils im Querschnitt die Form eines „gestreckten S" aufweisen, und wobei vorteilhaft jeder Steg die gesamte Längsseitenwand des Gurtes, an der er befestigt ist, über ihre gesamte Höhe bedeckt.This object is achieved in that a strap is provided at its two longitudinal sides each with a web, each web is attached to a longitudinal side wall of the belt, preferably by means of adhesive, and that the belt facing away from the end portions of the webs with the mutually facing Surfaces are connected to each other surface, preferably by means of adhesive, wherein the webs in each case in cross-section in the form of a "stretched S", and wherein advantageously each web covers the entire longitudinal side wall of the belt to which it is attached over its entire height.
Vorzugsweise schließen die Enden der Stege, die sich entlang der Längsseitenwand des Gurtes erstrecken, mit zumindest einem Teil der Außenseiten des Gurtes bündig ab, insbesondere durch eine spannabhebende Bearbeitung am zusammengesetzten Bauelement bzw. einem Bauelementrohling.Preferably, the ends of the webs extending along the longitudinal side wall of the webbing terminate flush with at least a portion of the outside of the webbing, in particular by a chucking operation on the assembled component or a component blank.
Zur Erzielung einer hohen Tragfähigkeit bei gleichzeitig guter Torsionssteifigkeit liegt das Verhältnis der Gurtbreite zur Steghöhe im Bereich zwischen 1 :20 und 1:1, vorzugsweise im Bereich von 1 :6 bis 1 : 1, insbesondere im Bereich von 1 :3,5 bis 1 :2,5.To achieve a high load-bearing capacity and at the same time good torsional rigidity, the ratio of the belt width to the web height is in the range between 1:20 and 1: 1, preferably in the range from 1: 6 to 1: 1, in particular in the range from 1: 3.5 to 1 : 2.5.
Vorzugsweise ist das Bauelement dadurch gekennzeichnet, dass es zur Gänze aus Holz gebildet ist, wobei der Gurt vorzugsweise aus Schnittholz und die Stege vorzugsweise aus Sperrholz gefertigt sind, wobei zweckmäßig die Stege von einem Dreischichtsperrholz gebildet sind und sich die Holzfasern der beiden Außenschichten des Sperrholzes in Längsrichtung des Bauelements erstrecken. Ausbildungen dieser Art ergeben ein besonders gutes Verhältnis von Eigengewicht zu Tragfestigkeit. Zudem lässt sich für den Gurt minderwertiges Schnittholz aus der Sägeindustrie verwenden, wodurch eine Erhöhung der Wertschöpiung dieses Holzes gegeben ist.Preferably, the component is characterized in that it is formed entirely of wood, wherein the belt is preferably made of sawn timber and the webs are preferably made of plywood, wherein suitably the webs of a three-ply plywood are formed and extend the wood fibers of the two outer layers of the plywood in the longitudinal direction of the device. Formations of this kind give a particularly good ratio of dead weight to bearing strength. In addition, for the belt inferior sawn timber from the sawmill industry can be used, whereby an increase in the value added of this wood is given.
Ist das Bauelement mittels Klebstoffen zusammengefügt, so werden als Klebstoffe für Holz vorzugsweise Leime eingesetzt, insbesondere Kunstharzleime und PU-Leime. Weitere Möglichkeiten bieten moderne Kleber, die Mikrowellen- oder UV-härtend sind. Ebenso ist es möglich, statt flüssigem Leim auch eine Leimfolie zu verwenden.If the component is joined together by means of adhesives, glues are preferably used as adhesives for wood, in particular synthetic resin glues and PU glues. Other options include modern adhesives that are microwave or UV curing. It is also possible to use a glue film instead of liquid glue.
Vorzugsweise ist der von den Stegen und dem Gurt gebildete Hohlraum mit einem Werkstoff gefüllt, wie beispielsweise Quarzsand, Celluloseflocken, Schaumstoff, PU- Schaum, etc. Durch die Befüllung ergeben sich Lösungen für unterschiedlichste Aufgaben, wie z.B. zur Befriedigung von wärme- und schalltechnischen Anforderungen. Je nach Wunsch kann die Befüllung vor der Montage oder nach der Montage des Bauelements erfolgen, wobei letzteres den Vorteil einer einfacheren Manipulation ergibt, zumal dann nur die leichten hohlen Bauelemente transportiert werden müssen.Preferably, the cavity formed by the webs and the belt is filled with a material, such as quartz sand, cellulose flakes, foam, PU foam, etc. By filling solutions for a variety of tasks, such. for the satisfaction of heat and sound requirements. As desired, the filling can be done prior to assembly or after assembly of the device, the latter gives the advantage of easier manipulation, especially since then only the light hollow components must be transported.
Beanspruchungsmäßig günstig ist ein Bauelement mit einem symmetrischen Querschnitt, welcher dadurch gekennzeichnet ist, dass die miteinander flächig verbundenen Endbereiche der Stege mittig der Breite des Gurtes liegen.In terms of cost, a component with a symmetrical cross-section, which is characterized in that the mutually surface-connected end portions of the webs are located centrally of the width of the belt.
Zur Erhöhung der Tragfähigkeit ist ein sich vom Gurt bis zu den miteinander flächig verbundenen Endbereichen der Stege erstreckender Zwischensteg vorgesehen, wobei der Zwischensteg vorteilhaft an der Innenseite des Gurtes ansteht oder, nach einer anderen Ausführungsform, sich bis zur Außenseite des Gurtes durch diesen hindurch erstreckt. Der Zwischensteg muss sich nicht über die gesamte Länge des Bauelements erstrecken, sondern er kann von den Enden her eingeschoben werden oder durch einen Schlitz des Gurtes in dieses eingebracht werden.To increase the carrying capacity, an intermediate web extending from the belt to the areally connected end regions of the webs is provided, the intermediate web advantageously bearing against the inside of the belt or, according to another embodiment, extending as far as the outside of the belt. The gutter does not have to extend over the entire length of the component, but it can be inserted from the ends or inserted through a slot of the belt in this.
Eine weitere Erhöhung der Tragfähigkeit ergibt sich, wenn der Zwischensteg mit dem Bauelement mittels eines Klebers verbunden ist.A further increase in the load capacity results when the gutter is connected to the device by means of an adhesive.

Hierbei ist vorteilhaft der Gurt in einer Symmetrie-Mittelebene des Bauelements angeordnet.A modified Ausföhrungsform a component is characterized in that the two webs attached to the webs extend to both sides of the belt and both end portions of the two webs with the mutually facing surfaces with each other The webs in each case have a "double S" in cross-section, in which case the belt is advantageously arranged in a plane of symmetry of the component.
Erfindungsgemäße Bauelemente lassen sich durch Nebeneinanderanordnen und Aneinanderbefestigen zu Konstruktionselementen zusammensetzen, wobei vorteilhaft mindestens zwei Bauelemente nebeneinander liegend angeordnet sind, die Gurte der beiden Bauelemente eine Fläche bilden und die Bauelemente mit den hierbei aneinanderliegenden Endbereichen der Stege, dio an den Gurten angeordnet sind, miteinander verbunden sind, vorzugsweise mittels eines Klebers, und wobei weiters zwischen die beiden freien miteinander flächig verbundenen Endbereiche der Stege der benachbarten Bauelemente ein den Gurten der Bauelemente gegenüberliegender Gurt eingesetzt ist und mit den Endbereichen der miteinander flächig verbundenen Stege verbunden ist, vorzugsweise mittels eines Klebers.Inventive components can be assembled by juxtaposition and Aneinanderbefestigen to construction elements, wherein advantageously at least two components are arranged side by side lying, the straps of the two components form a surface and the components with the adjacent end portions of the webs, dio are arranged on the straps, connected to each other are, preferably by means of an adhesive, and wherein further between the two free mutually surface-connected end portions of the webs of the adjacent components, a belt of the components opposite belt is used and is connected to the end portions of the web-connected webs, preferably by means of an adhesive.
Eine Vielzahl von solcherart nebeneinander liegenden Bauelementen mit einer Vielzahl von den Gurten der Bauelemente gegenüberliegenden Gurten ergibt ein plattenförmiges Konstruktionselement.A plurality of such juxtaposed components with a plurality of the straps of the components opposite straps results in a plate-shaped construction element.
Plattenförmige Konstruktionselemente sind in unterschiedlichsten Varianten bekannt. So zeigt beispielsweise die AT 285 129 A ein Wandelement, gebildet von zwei im Abstand voneinander angeordneten, aus Brettern zusammengesetzten Abdeckwänden, zwischen denen in zickzackförmiger Anordnung Bretter eingesetzt sind, die an den beiden Abdeckwänden jeweils zur Anlage gelangen. Sie sind gegebenenfalls mit den Abdeckwänden verleimt. Diese Konstruktion ist nicht nur schwer, sondern auch sehr aufwändig herzustellen.Plate-shaped construction elements are known in a wide variety of variants. Thus, for example, the AT 285 129 A shows a wall element formed by two spaced-apart, composed of boards cover walls between which boards are used in a zigzag arrangement, which come to the two cover walls in each case to the plant. If necessary, they are glued to the cover walls. This construction is not only difficult, but also very expensive to produce.
Aus der WO 02/06606 Al ist ein plattenförmiges Bauelement bekannt, bei dem ebenfalls zwei Abdeckplatten, die im Abstand voneinander liegen, mit dazwischen liegenden Stegen in Verbindung stehen, wobei die Stege sich jeweils rechtwinkelig zu den beiden Abdeckplatten erstrecken.From WO 02/06606 Al a plate-shaped component is known, in which also two cover plates, which are at a distance from each other, are in communication with webs lying therebetween, wherein the webs each extend at right angles to the two cover plates.
Weiters sind noch aus der GB 560913 A plattenförmige Konstruktionselemente bekannt, zwischen denen ebenfalls eine zickzackartige Einlage entweder liegend oder auch stehend unter Bildung einer wabenartigen Struktur vorgesehen ist. Eine wabenartige Struktur zwischen Plattenelementen ist auch aus der AT 196 113 A bekannt. Die Erfindung betrifft weiters ein Verfahren zum Herstellen eines Bauelements der erfindungsgemäßen Art. Dieses Verfahren ist dadurch gekennzeichnet, dass an einem Gurt, vorzugsweise gefertigt aus Schnittholz, an den Längsseitenflächen sich vertikal vom Gurt wegerstreckende Stege unter Bildung eines U-förmigen Querschnitts eines Bauelementrohlings befestigt, vorzugsweise angeklebt werden, worauf die freien, dem Gurt gegenüberliegenden Endbereiche der Stege in eine sich keilförmig verjüngende Nut, die mit ihrer engsten Stelle in eine parallelwandige Nut übergeht, eingebracht werden und durch Bewegen des Bauelementrohlings entlang der keilförmigen Nut bis in die parallelwandige Nut durch die Keilform unter Verformung miteinander in Kontakt gelangen und in der parallelwandigen Nut in Kontakt verbleiben, wobei die miteinander in Kontakt gelangenden Innenseiten der Stege zuvor mit einem Klebstoff versehen wurden.Furthermore, from GB 560913 A plate-shaped construction elements are known, between which also a zigzag-like insert is provided either lying or standing to form a honeycomb-like structure. A honeycomb structure between plate elements is also known from AT 196 113 A. The invention further relates to a method for producing a component of the type according to the invention. This method is characterized in that on a belt, preferably made of sawn timber, webs extending vertically away from the belt fasten to the longitudinal side surfaces to form a U-shaped cross-section of a component blank. glued preferably, whereupon the free, the belt opposite end portions of the webs in a wedge-shaped tapered groove, which merges with its narrowest point in a parallel-walled groove, and introduced by moving the component blank along the wedge-shaped groove into the parallel-walled groove through the Form wedge shape come under contact with each other and remain in contact in the parallel-walled groove, wherein the contacting inner sides of the webs were previously provided with an adhesive.
Vorzugsweise erfolgt das Bewegen des Bauelementrohlings entlang der Nuten mittels eines sich entlang des Bauelementrohlings erstreckenden Zugelements, wie eines Seiles, das an einem Ende des Bauelementrohlings befestigt wird und welches Seil mittels einer Winde gezogen wird. Selbstverständlich kann der Bauelementrohling auch entlang der Nut durch Druckkräfte verschoben werden.Preferably, moving the component blank along the grooves by means of a along the component blank extending tension element, such as a rope which is attached to one end of the component blank and which cable is pulled by a winch. Of course, the component blank can also be displaced along the groove by compressive forces.
Eine Vorrichtung zur Herstellung eines erfindungsgemäßen Bauelements ist gekennzeichnet durch eine in Längsrichtung keilförmige Nut, deren größte Breite gleich oder größer ist als die Summe der Breite des Gurtes und der beiden Dicken der Stege und dessen engste Breite gleich oder geringfügig größer ist als die beiden Dicken der Stege in Summe, und durch eine an die engste Breite der keilförmigen Nut anschließende oder anschließbare, in Längsrichtung parallelwandige Nut, deren Längserstreckung gleichgerichtet ist der Längserstreckung der keilförmigen Nut und deren Breite etwa der engsten Breite der keilförmigen Nut entspricht, wobei die Tiefe der beiden Nuten mindestens etwa der Breite der miteinander zu verbindenden Endbereiche der Stege des Bauelements entspricht.A device for producing a component according to the invention is characterized by a wedge-shaped groove in the longitudinal direction whose largest width is equal to or greater than the sum of the width of the belt and the two thicknesses of the webs and whose narrowest width is equal to or slightly greater than the two thicknesses of Webs in total, and by a subsequent to the narrowest width of the wedge-shaped groove or connectable, longitudinally parallel-walled groove whose longitudinal extent is rectified, the longitudinal extension of the wedge-shaped groove and whose width corresponds approximately to the narrowest width of the wedge-shaped groove, wherein the depth of the two grooves at least approximately corresponds to the width of the end regions of the webs of the component to be joined together.
Eine bevorzugte Ausführungsform ist gekennzeichnet durch eine einen Bauelementrohling durch die keilförmige Nut in die parallelwandige Nut bewegende Bewegungseinrichtung, vorzugsweise eine den Bauelementrohling ziehende Bewegungseinrichtung, wie eine Seilzugeinrichtung, wobei hierzu eine Seilzugeinrichtung, deren Seil entlang des Bauelementrohlings bis an dessen Ende bringbar ist und dort befestigbar ist, sich als vorteilhaft erwiesen hat. Für eine Serienproduktion ist es zweckmäßig, wenn zwei oder mehrere nebeneinander angeordnete, parallelwandige Nuten und eine fluchtend zu diesen von Nut zu Nut verbringbare keilförmige Nut vorgesehen ist.A preferred embodiment is characterized by a movement of a component blank through the wedge-shaped groove in the parallel-walled groove moving means, preferably a device blank pulling movement device, such as a cable pulling device, for this purpose a cable pulling device, the rope along the component blank can be brought to the end and fastened there is, has proven to be beneficial. For a series production, it is expedient if two or more juxtaposed, parallel-walled grooves and an aligned to these groove-to-groove can be provided wedge-shaped groove is provided.
Die Eigenspannung der Stege, insbesondere wenn diese aus Sperrholz gebildet sind, in der parallelwandigen Nut ist so groß, dass sich Druckkräfte nach außen ergeben, also in Wirkrichtung senkrecht zum Nutgrund von der Nut weg, welche Druckkräfte ein Herausspringen des Bauelements bewirken könnten. Folglich ist ein Gegendruck in Richtung zur Nut senkrecht zum Nutgrund zweckmäßig. Dieser Gegendruck wird dadurch bewirkt, dass eine kraftaufnehmende Führungseinrichtung im Abstand der Nut, an der der Gurt des Bauelementrohlings zur Anlage gelangt, vorgesehen ist.The residual stress of the webs, in particular if they are formed of plywood, in the parallel-walled groove is so large that pressure forces result to the outside, ie in the effective direction perpendicular to the groove bottom away from the groove, which pressure forces could cause the component to pop out. Consequently, a back pressure in the direction of the groove perpendicular to the groove bottom is appropriate. This back pressure is effected by providing a force-absorbing guide device at a distance from the groove on which the belt of the component blank comes into contact.

Die beiden freien Enden der Stege 3, 4 sind mit ihren Endbereichen 7 flächig miteinander verbunden, und zwar mit den gegeneinandergerichteten Flächen 8, 9 und ebenfalls vorzugsweise mittels Klebstoff. Hierdurch weisen die Stege 3, 4 jeweils im Querschnitt die Form eines gestreckten S auf. Der Gurt 2 ist vorzugsweise aus Schnittholz, das billig aus der Sägeindustrie zur Verfügung steht und in Längsrichtung auch aus mehreren miteinander in üblicher Weise verbundenen Einzelteilen zusammengesetzt sein kann, gebildet. Die Stege 3, 4 sind zweckmäßig von Sperrholz gebildet, und zwar vorzugsweise aus dreischichtigem Sperrholz, wobei die beiden Außenschichten sich mit ihren Längsfasern längs des Bauelements erstrecken. Das Bauelement weist im Querschnitt eine Symmetrielinie 10 auf, d.h., dass die beiden miteinander verbundenen Endbereiche 7 der Stege 3, 4 vertikal mittig der Breitenerstreckung des Gurtes 2 zu liegen kommen.The illustrated in Fig. 1 component 1 is formed by a belt 2 and two webs 3, 4, wherein the webs are fixed to the side surfaces 5, 6 of the belt 2, namely on its narrow side surfaces, preferably by gluing. The two free ends of the webs 3, 4 are connected with their end portions 7 flat with each other, with the oppositely directed surfaces 8, 9 and also preferably by means of adhesive. As a result, the webs 3, 4 in each case in cross section in the form of an elongated S on. The belt 2 is preferably made of sawn timber, which is cheap from the sawing industry available and can be composed in the longitudinal direction of a plurality of interconnected in a conventional manner items. The webs 3, 4 are expediently formed of plywood, preferably of three-layer plywood, wherein the two outer layers extend with their longitudinal fibers along the component. The structural element has a line of symmetry 10 in cross-section, that is to say that the two interconnected end regions 7 of the webs 3, 4 come to rest vertically in the middle of the widthwise extension of the belt 2.
Das erfindungsgemäße Bauelement 1 weist den Vorteil auf, dass es prinzipiell aus unterschiedlichsten Materialien insgesamt und auch aus unterschiedlichen Materialien für jeweils Gurt 2 und Stege 3, 4 gebildet sein kann, wobei für die Stege 3, 4 in erster Linie Materialien in Frage kommen, die Schubkräfte aufnehmen können und zudem biegsam und vorzugsweise klebbar sind. So können die Stege 3, 4 beispielsweise aus Karton, Kunststoff, Blech, mehrlagigem Sperrholz oder anderen Holzwerkstoffen gebildet sein. Ebenso ist es möglich, den Gurt 2 aus unterschiedlichen Werkstoffen, wie Kunststoff, Karton, mehrlagigem Sperrholz oder auch aus Metall zu bilden.The component 1 according to the invention has the advantage that it is made of different materials as a whole and also of different materials for each belt 2 and webs 3, 4 may be formed, for the webs 3, 4 are primarily materials in question, which can absorb shear forces and are also flexible and preferably glued. Thus, the webs 3, 4 may be formed for example of cardboard, plastic, sheet metal, multi-ply plywood or other wood materials. It is also possible to form the belt 2 of different materials, such as plastic, cardboard, multi-ply plywood or metal.
Gemäß der in Fig. 2 dargestellten Ausführungsform ist in den vom Gurt 2 und den Stegen 3, 4 eingeschlossenen Hohlraum 11 ein Zwischensteg 12 eingesetzt, und zwar von den Endseiten des Bauelements 1 her eingeschoben. Dieser Zwischensteg 12, der gegebenenfalls aus dem gleichen Material gebildet ist wie die Stege 3, 4, kann mit den Stegen 3, 4 bzw. mit dem Gurt 2 durch Kleben verbunden sein.According to the embodiment shown in Fig. 2, a gutter 12 is inserted into the enclosed by the belt 2 and the webs 3, 4 cavity 11, and inserted from the end sides of the device 1 ago. This intermediate web 12, which is optionally formed of the same material as the webs 3, 4, may be connected to the webs 3, 4 or to the belt 2 by gluing.
Gemäß der in Fig. 3 dargestellten Ausführungsform sind Zwischenstege 12 in schlitzförmige Ausnehmungen 13 des Gurtes 2 eingesetzt und sie erstrecken sich bis zur Außenseite 14 des Gurtes 2. Die in Fig. 2 und 3 dargestellten Varianten des Bauelements 1 ergeben eine besonders hohe Tragkraft bei gesteigerter TorsionsfestigkeitAccording to the embodiment shown in Fig. 3, intermediate webs 12 are inserted into slot-shaped recesses 13 of the belt 2 and they extend to the outer side 14 of the belt 2. The variants of the component 1 shown in Fig. 2 and 3 give a particularly high load capacity with increased torsional strength
Das in Fig. 4 und 5 dargestellte Konstruktionselement 15 ist aus mehreren nebeneinander angeordneten und miteinander verbundenen Bauelementen 1 gemäß Fig. 1 gebildet, wobei die jeweils freien Enden der miteinander verbundenen Stege 3, 4 der einzelnen Bauelemente 1 mittels eines Gurtes 16 miteinander verbunden sind, vorzugsweise ebenfalls durch Leimen. In Fig. 6 ist ein Konstruktionselement veranschaulicht, bei dem das Verhältnis der Bauelementbreite 17 zur Bauelementhöhe 18 in etwa bei 1:1,5 liegt, wogegen gemäß Fig. 4 dieses Verhältnis knapp über 1 :3 liegt.The construction element 15 shown in FIGS. 4 and 5 is formed from a plurality of juxtaposed and interconnected components 1 according to FIG. 1, the respective free ends of the interconnected webs 3, 4 of the individual components 1 being connected to one another by means of a belt 16, preferably also by gluing. FIG. 6 illustrates a construction element in which the ratio of the component width 17 to the component height 18 is approximately 1: 1.5, whereas according to FIG. 4 this ratio is just above 1: 3.
Wie aus Fig. 6 und 7 ersichtlich ist, ergibt sich durch das Verhältnis 1:1,5 eine stärkere S- förmige Biegung der Stege 3, 4, was bei hinreichender Biegsamkeit der Stege 3, 4 zulässig ist und eine erhöhte Festigkeit ergibt, insbesondere beim Auftreten von Schubkräften zwischen den Gurten 16 an der Oberseite des Konstruktionselements 15 und den Gurten 2 an der Unterseite des Konstruktionselements 15.As is apparent from FIGS. 6 and 7, the ratio 1: 1.5 results in a stronger S-shaped bend of the webs 3, 4, which is permissible given sufficient flexibility of the webs 3, 4 and results in increased strength, in particular on the occurrence of shear forces between the straps 16 at the top of the structural element 15 and the straps 2 at the bottom of the structural element 15th
Fig. 8 veranschaulicht eine Ausführungsform ähnlich der Fig. 6, jedoch sind dort die Hohlräume 11 mit PU-Schaum 19 gefüllt, der auch zur Erhöhung der Tragfestigkeit beiträgt. Diese Hohlräume 11 können je nach Bedarf (Schallschutz, Erhöhung der Tragfestigkeit, Wärmedämmung, etc.) mit unterschiedlichen Materialien gefüllt sein. Fig. 10 zeigt ein Konstruktionselement 15', gebildet von einer Ausfiihrungsform von Bauelementen 1', bei denen jeweils sich die beiden am Gurt 2 befestigten Stege 3', 4' nach beiden Seiten des Gurtes 2 erstrecken und beide Endbereiche 7, T der beiden Stege 3', 4' mit den zueinandergerichteten Flächen miteinander flächig verbunden sind. Hierdurch weisen die Stege 3', 4' im Querschnitt ein gestrecktes Doppel-S auf.Fig. 8 illustrates an embodiment similar to Fig. 6, but there are the cavities 11 filled with PU foam 19, which also contributes to increase the bearing strength. These cavities 11 may be filled with different materials as needed (sound insulation, increase the bearing strength, thermal insulation, etc.). Fig. 10 shows a construction element 15 ', formed by an embodiment of components 1', in each of which the two webs 3 ', 4' fastened to the belt 2 extend to both sides of the belt 2 and both end regions 7, T of the two webs 3 ', 4' with the mutually facing surfaces are connected to each other surface. As a result, the webs 3 ', 4' in cross-section on an elongated double-S.
In Fig. 11 ist eine Vorrichtung 20 zur Herstellung eines Bauelements 1, wie es in Fig. 1 gezeigt ist, veranschaulicht. Diese Vorrichtung 20 umfasst einen kastenförmigen Tunnel 21, der zur Aufnahme von nach außen wirkenden Kräften mit in seiner Längsrichtung im Abstand voneinander angeordneten Rahmen 22 verstärkt ist.FIG. 11 illustrates a device 20 for producing a component 1, as shown in FIG. 1. This device 20 comprises a box-shaped tunnel 21 which is reinforced to receive outward forces with frames 22 spaced apart in its longitudinal direction.
Am Boden 23 des Tunnels befinden sich Leisten 24 in einem Abstand, der geringfügig größer ist als die Dicke 25 zweier miteinander verbundener Endbereiche 7 der Stege 3, 4. Diese Leisten 24 bilden sozusagen parallelwandige Nuten 26, deren Höhe ebenfalls geringfügig größer bemessen ist als die Höhe, über die die beiden Endbereiche 7 der Stege 3, 4 miteinander verbunden sind. Die Breite der Stege entspricht vorzugsweise der Breite eines Gurtes 2.At the bottom 23 of the tunnel are strips 24 at a distance which is slightly greater than the thickness 25 of two interconnected end portions 7 of the webs 3, 4. These strips 24 form, so to speak, parallel-walled grooves 26 whose height is also dimensioned slightly larger than that Height over which the two end portions 7 of the webs 3, 4 are interconnected. The width of the webs preferably corresponds to the width of a belt 2.
Eine keilförmige Nut 27, ebenfalls gebildet von Leisten 28 etwa gleicher Art wie die Leisten 24, ist an einer Tragvorrichtung 29 vorgesehen, die von parallelwandiger Nut 26 zu parallelwandiger Nut 26 in Richtung der Pfeile 30 verschiebbar ist. Diese keilförmige Nut 27, deren Keilform sich in Längsrichtung zu den parallelwandigen Nuten 26 verjüngt, dient dazu, einen Bauelementrohling 31, der gebildet ist von einem Gurt 2 und zwei sich längs des Gurtes 2 erstreckenden und an diesen befestigten, noch unverformten Stegen 3, 4, die parallel zueinander liegen, aufzunehmen und bei Verschieben des Bauelementrohlings in Richtung des Pfeiles 32 der Fig. 12 mit aneinander angepressten Endbereichen 7 der Stege 3, 4 in die parallelwandige Nut 26 einzubringen. Hierbei sind die Endbereiche 7 der Stege 3, 4, die miteinander verbunden werden sollen, vorher mit einem Klebstoff bestrichen. Um ein Herausspringen des Bauelementrohlings 31 aus der parallelwandigen Nut 27 zu verhindern - was durch die sich bei der Verformung der Stege 3, 4 ergebenden Druckkräfte bewirkt wird - ist die Höhe des Tunnels 21 derart bemessen, dass der Gurt 2, wie aus Fig. 12 ersichtlich, an der Innenfläche 33 des Tunnels 21 zur Anlage gelangt, die den parallelwandigen Nuten 26 gegenüberliegt. Anhand der Fig. 13A bis 13D ist gezeigt, wie die Verformung der Stege 3, 4 beim Längsverschieben entlang der keilförmigen Nut 27 vor sich geht.A wedge-shaped groove 27, also formed by strips 28 of approximately the same type as the strips 24, is provided on a support device 29 which is displaceable from parallel-walled groove 26 to parallel-walled groove 26 in the direction of the arrows 30. This wedge-shaped groove 27, whose wedge shape tapers in the longitudinal direction to the parallel-walled grooves 26, serves a component blank 31, which is formed by a belt 2 and two extending along the belt 2 and secured thereto, still undeformed webs 3, 4th , which are parallel to each other, absorb and bring in moving the component blank in the direction of arrow 32 of FIG. 12 with pressed-together end portions 7 of the webs 3, 4 in the parallel-walled groove 26. Here, the end portions 7 of the webs 3, 4, which are to be joined together, previously coated with an adhesive. In order to prevent jumping out of the component blank 31 from the parallel-walled groove 27 - which is caused by the compressive forces resulting from the deformation of the webs 3, 4 - the height of the tunnel 21 is dimensioned such that the belt 2, as shown in FIG can be seen, comes to rest on the inner surface 33 of the tunnel 21, which faces the parallel-walled grooves 26. The deformation of the webs 3, 4 during longitudinal displacement along the wedge-shaped groove 27 is shown with reference to FIGS. 13A to 13D.
Das Verschieben des Bauelementrohlings 31 kann durch Druckkräfte oder auch durch Zugkräfte erfolgen, insbesondere ist es vorteilhaft, ein Seil durch den zwischen den Stegen 3, 4 liegenden Hohlraum des Bauelementrohlings 31 zu fuhren und an dessen hinterem Ende zu befestigen und das Seil, das sich auch durch den Tunnel 21 erstreckt, mittels einer Seilwinde Zugkräften, die die Bewegung des Bauelementrohlings 31 in Richtung des Pfeiles 32 bewirken, auszusetzen.The displacement of the component blank 31 can be done by compressive forces or by tensile forces, in particular it is advantageous, a rope through the between the webs 3, 4 lying cavity of the component blank 31 to drive and fasten at the rear end and the rope, which also extends through the tunnel 21, by means of a winch tensile forces that cause the movement of the component blank 31 in the direction of arrow 32, suspend.
Das Bilden von plattenförmigen Konstruktionselementen 15 aus den einzelnen Bauelementen 1 bzw. 1 ' erfolgt zweckmäßig in einem Pressbett, in dem nebeneinanderliegende Bauelemente 1, 1' unter vorherigem Aufbringen von Klebstoff an den aneinander zur Anlage gelangenden Seiten gegeneinander verpresst werden. Vorher sind jedoch zwischen die freien Endbereiche 7 der miteinander verbundenen Stege 3, 4 bzw. 3', 4' der einzelnen Bauelemente 1, 1' einem Gurt 2 eines Bauelements 1, 1' entsprechende Gurte 16 eingesetzt.The formation of plate-shaped construction elements 15 from the individual components 1 and 1 'is expediently carried out in a press bed in which adjacent components 1, 1' are pressed together with previous application of adhesive to the abutting sides. Before, however, between the free end portions 7 of the interconnected webs 3, 4 and 3 ', 4' of the individual components 1, 1 'a belt 2 of a component 1, 1' corresponding belts 16 are used.
Die Verbindung der Stege 3, 4, 3', 4' mit den Gurten 2, 16 bzw. der Bauelemente 1, 1' miteinander erfolgt bei Verwendung von Holz vorzugsweise mittels Leim, insbesondere Kunstharzleim, bei anderen Materialien für die Einzelelemente des Bauelements erfolgt das Verbinden dieser Einzelteile artgerecht, also beispielsweise durch Löten, Schweißen, Schrauben, etc. The connection of the webs 3, 4, 3 ', 4' with the straps 2, 16 or the components 1, 1 'together takes place when using wood, preferably by means of glue, in particular resin glue, in other materials for the individual elements of the device is the Connecting these items in an appropriate manner, for example, by soldering, welding, screws, etc.
