Abstract

The system described is intended for flat and curved supporting structures comprising hollow-section bars (12, 13) and nodal elements (18, 20) composed of hollow elements which can be assembled in a releasable manner with the hollow-section bars (12, 13) by means of screw fasteners (22, 24, 26) and by which an interconnectable and at least partly closed-off pipe network can be produced, whereby said network can be filled with a fluid or gaseous medium by means of a feed and discharge line. The nodal elements (18, 20) have a cup- or ring-shaped configuration and have, on their external surfaces, working and assembly surfaces (30, 32) intended for sealed assembly with the working and connection parts (34, 36) of the hollow sections (12, 13) or the adjacent nodal elements (18, 20). These surfaces (30, 32) each have at least one through-hole (40, 42) for securing screws which have a through-hole (60, 62), preferably axial, connecting the internal nodal space (50, 52) with the inside (54, 56) of the hollow-section bars (12, 13) assembled with the nodal elements (18, 20). The nodal elements (18, 20) are each provided at least with one aperture (64, 66, 68) which can be closed hermetically by means of a cover (70, 72, 74) which is fixed in a removable manner on the nodal body (18, 20).

Description

Die Erfindung betrifft ein Raumfachwerk nach dem Oberbegriff des Anspruches 1.The invention relates to a space framework according to the preamble of claim 1.

Bei den bekannten Systemen der eingangs genannten Art, wie sie z.B. in der DE-PS 24 28 524 beschrieben sind, sind die Verbindungsschrauben einstückig mit dem kugelförmigen Knotenkörper verbunden. Die Aufgabe des dort beschriebenen Knotenkörpers ist, nicht nur bestimmte Hohlprofile miteinander zu verbinden, er dient auch dazu, die bzw. das zur Kühlung dienende Flüssigkeit bzw. Gas von dem Speicher zu den Abnehmern zu leiten. Im bekannten Falle ist zwar eine gute Verbindung zwischen den Hohlprofilen und den Knotenelementen herstellbar, und zwar vor allem dann, wenn es sich um Hohlprofilelemente mit einem kreisrunden Querschnitt handelt. Diese Verbindung erfordert aber mehrere, aufeinander abgestimmte Verbindungsteile, die das Konten-Stab-System aufwendig und kostenintensiv machen. Ein weiterer Nachteil des bekannten Systems besteht darin, daß es vor Brand bzw. Überhitzung nur mittelbar geschützt ist. Dies wird dadurch erreicht, daß im Bedarfsfall durch die Hohlprofile Kühlmedium geleitet wird.In the known systems of the type mentioned, as described for example in DE-PS 24 28 524, the connecting screws are integrally connected to the spherical node body. The task of the knot body described there is not only to connect certain hollow profiles to one another, it also serves to guide the liquid or gas, which is used for cooling, from the store to the customers. In the known case, a good connection can be made between the hollow profiles and the node elements, especially when it comes to hollow profile elements with a circular cross section. However, this connection requires several, coordinated connecting parts, which make the accounts staff system complex and cost-intensive. Another disadvantage of the known system is that it is only indirectly protected against fire or overheating. This is achieved by passing cooling medium through the hollow profiles if necessary.

Ferner ist in der DE-A 31 33 946 ein Tragwerk und in der DE-A 29 17 422 ein aus Rohren und Kugeln bestehendes System zur Herstellung eines Baugitters beschrieben. Die Verbindung bei diesen Raumfachwerken erfolgt mittels Schrauben. Sie sind aber nicht dafür geeignet, Flüssigkeit oder Gase zu transportieren.Furthermore, DE-A 31 33 946 describes a supporting structure and DE-A 29 17 422 describes a system consisting of pipes and balls for the production of a building grid. These space trusses are connected by means of screws. However, they are not suitable for transporting liquids or gases.

Es ist daher Aufgabe der Erfindung, das gattungsgemäße Knoten-Stab-System ohne unangemessenen konstruktiven Aufwand so weiterzubilden, daß der Zusammenbau ebener und gekrümmter räumlicher Fachwerke deutlich einfacher erfolgen kann. Darüber hinaus soll das Knoten-Stab-System durch einfache Maßnahmen so umgebaut werden können, daß es als Feuerlöschanlage dienen kann.It is therefore an object of the invention to further develop the generic knot-rod system without undue constructive effort so that the assembly of flat and curved spatial trusses can be done much easier. In addition, the node-rod system should be able to be converted by simple measures so that it can serve as a fire extinguishing system.

Die gestellte Aufgabe wird erfindungsgemäß durch die kennzeichenden Merkmale des Anspruches 1 gelöst.The object is achieved according to the invention by the characterizing features of claim 1.

Man erkennt, daß bei der Erfindung nicht nur die Knotenkörper, sondern auch die Verbindung zwischen den Knotenkörpern und den Profilstäben einfach herstellbar ist. Bei der Erfindung wird daher die Verbindung zwischen den Profilstäben und den Knotenkörpern so hergestellt, daß die Verbindungsschrauben durch den Durchbruch in den Innenraum des Knotenkörpers gebracht und danach in die für die Verbindungsschrauben vorgesehenen Öffnungen angeordnet werden. Danach wird die Verbindung zwischen den Schrauben und den Profilstäben hergestellt. Schließlich wird der Deckel mit dem Knotenkörper dicht verbunden. Eine solche Verbindung zwischen dem Knotenkörper und den Profilstäben ist daher geeignet, ein Medium von einem Profilstab in den anderen zu führen.It can be seen that not only the knot bodies, but also the connection between the knot bodies and the profiled bars can be easily produced in the invention. In the invention, therefore, the connection between the profile bars and the knot bodies is made such that the connecting screws are brought through the opening into the interior of the knot body and then arranged in the openings provided for the connecting screws. Then the connection between the screws and the profile bars is established. Finally, the lid is tightly connected to the node body. Such a connection between the node body and the profile bars is therefore suitable for guiding a medium from one profile bar into the other.

Weitere zweckmäßige und vorteilhafte Maßnahmen der Erfindung gehen aus den Unteransprüchen hervor.Further expedient and advantageous measures of the invention emerge from the subclaims.

Sind die Knotenkörper mit Bezug auf eine ihrer Achsen symmetrisch ausgebildet, wobei die Arbeits- und Verbindungsflächen der Knotenkörper eben sein können, dann ist eine gleichmäßige Belastung des Knotenkörpers sichergestellt, es wird vor allem vermieden, daß es zur Deformation der Knotenkörper kommen kann. Eine zweckmäßige Maßnahme der Erfindung sieht vor, daß die Arbeits-und Verbindungsflächen der Knotenkörper deckungsgleich mit den Arbeits- und Verbindungspartien der Hohlprofile ausgebildet sind. Hierdurch wird nicht nur eine optimale Nutzung der Außenfläche des Knotenkörpers gewährleistet, es wird auch sichergestellt, daß sich die Profilstäbe am Knotenkörper über ihre ganzen Arbeits-und Verbindungspartien abstützen. Ist der Knotenkörper napfförmig ausgebildet, dann ist es zweckmäßig, ihn so auszubilden, daß er zwölf Arbeits-und Verbindungsflächen besitzt. Bei ebenen räumlichen Fachwerken werden solche Knoten am häufigsten eingesetzt. Hierbei ist es zweckmäßig, wenn die jeweils benachbarten Arbeits- und Verbindungsflächen der Knotenkörper einen Winkel von 45° bilden.If the node bodies are symmetrical with respect to one of their axes, and the working and connecting surfaces of the node bodies can be flat, then an even loading of the node body is ensured, and above all it is avoided that the node bodies can be deformed. An expedient measure of the invention provides that the working and connecting surfaces of the node bodies are congruent with the working and connecting parts of the hollow profiles. This not only ensures optimal use of the outer surface of the knot body, it also ensures that the profiled bars are supported on the knot body over their entire working and connecting parts. If the node body is cup-shaped, it is expedient to design it in such a way that it has twelve working and connecting surfaces. Such nodes are most often used for flat spatial trusses. It is expedient here if the adjacent working and connecting surfaces of the node bodies form an angle of 45 °.

Ist der Knotenkörper ring- bzw. röhrenförmig ausgebildet, dann ist es zweckmäßig, wenn er für die Konstruktion von Kuppeln und zweiachsig gekrümmten Gitterschalen entweder fünf, sechs oder acht Arbeits- und Verbindungsflächen besitzt. In diesen Fällen ist nach anspruch 14 die Längsmittelachse der Verbindungsstäbe gegenüber den Arbeits- und Verbindungspartien der Knotenkörper geneigt.If the node body is ring-shaped or tubular, then it is expedient if it has either five, six or eight working and connecting surfaces for the construction of domes and biaxially curved lattice shells. In these cases, the longitudinal central axis of the connecting rods is inclined relative to the working and connecting parts of the node bodies.

Die Herstellung der Verbindungen zwischen den Knotenkörpern und Profilstäben kann ferner so verbessert werden, indem die Öffnung der Knotenkörper so bemessen ist, daß die Verbindungsschrauben durch als Bohrungen ausgebildete Durchbrüche der Knotenkörper von innen nach außen einsteckbar sind. Hierbei werden zweckmäßigerweise Inbusschrauben benutzt, deren Köpfe im Innenraum der Knotenkörper angeordnet sind. Eine gute und dichte Verbindung zwischen dem Deckel und dem Knotenkörper ist dadurch herstellbar, daß die Öffnung des Knotenkörpers sich von außen nach innen verjüngt und daß der Deckel im Verbindungsbereich komplementär zu dem Knotenkörper ausgebildet ist. Hierbei ist es vorteilhaft, wenn der Deckel mit dem Knotenkörper mittels mehrerer Schrauben verbindbar ist. Dabei können die Schrauben selbstschneidend sein und in eingeprägte Gewindekanäle der ring- bzw. röhrenförmigen Profilabschnitte eingreifen.The production of the connections between the knot bodies and profiled bars can also be improved in such a way that the opening of the knot body is dimensioned such that the connecting screws can be inserted from the inside to the outside through openings in the knot body designed as bores. In this case, Allen screws are expediently used, the heads of which are arranged in the interior of the node body. A good and tight connection between the cover and the knot body can be produced in that the opening of the knot body tapers from the outside inwards and that the cover in the connection area is complementary to the knot body. It is advantageous here if the cover can be connected to the node body by means of several screws. The screws can be self-tapping and can engage in embossed thread channels of the ring or tubular profile sections.

Soll das Knoten-Stab-System gleichzeitig als Löschungsanlage dienen, dann ist es zweckmäßig, wenn der Deckel als Sprinkleranlage ausgebildet ist. Hierbei kann vorgesehen sein, daß der Deckel eine Bohrung mit Gewinde besitzt, in die eine Feuerlöschanlage, insbesondere eine Sprinkleranlage, einschraubbar ist.If the node-rod system is also to be used as an extinguishing system, then it is expedient if the cover is designed as a sprinkler system. It can be provided that the cover has a threaded bore into which a fire extinguishing system, in particular a sprinkler system, can be screwed.

Handelt es sich bei der Erfindung um ein Knoten-Stab-System mit Hohlprofilstäben, deren Längsmittelachsen die Arbeits- und Verbindungspartien unter einem von 90° verschiedenen Winkel schneiden, dann ist es zweckmäßig, wenn zwischen den im Innenraum des Knotenkörpers angeordneten Köpfen der Verbindungsschrauben und dem Knotenkörper Unterlegscheiben angeordnet sind, die sich verjüngen, wobei der Neigungswinkel der Unterlegscheiben dem Winkel entspricht, den die Längsmittelachsen mit den Arbeits- und Verbindungspartien einschließen.If the invention is a knot-rod system with hollow profile bars whose longitudinal central axes intersect the working and connecting parts at an angle other than 90 °, then it is expedient if the connecting screws and the heads arranged in the interior of the knot body Knot body washers are arranged that taper, the angle of inclination of the washers corresponds to the angle that the longitudinal central axes include the working and connecting parts.

The node bodies 18, 20 each have at least one opening 64, 66, 68, which can be sealed tightly by means of a cover 70, 72, 74 which can be releasably connected to the node body 18, 20.

Man erkennt, daß die Knotenkörper 18,20 mit Bezug auf eine ihrer Achsen symmetrisch ausgebildet und ihre Arbeits- und Verbindungsflächen 30,32 eben sind. Hierbei sind diese Arbeits- und Verbindungsflächen 30,32 der Knotenkörper 18,20 vorzugsweise deckungsgleich mit den Arbeits- und Verbindungspartien 34,36 der Hohlprofile 12,16. Der in den Fig. 1 bis 3 dargestellte napfförmige Knotenkörper 18 besitzt zwölf Arbeits- und Verbindungsflächen 30, wobei die jeweils benachbarten Arbeits- und Verbindungsflächen 30,31 des Knotenkörpers 18 einen Winkel von 45° bilden.It can be seen that the node bodies 18, 20 are symmetrical with respect to one of their axes and their working and connecting surfaces 30, 32 are flat. These working and connecting surfaces 30, 32 of the node bodies 18, 20 are preferably congruent with the working and connecting parts 34, 36 of the hollow profiles 12, 16. The cup-shaped knot body 18 shown in FIGS. 1 to 3 has twelve working and connecting surfaces 30, the adjacent working and connecting surfaces 30, 31 of the knot body 18 forming an angle of 45 °.

Der ring- bzw. röhrenförmige Knotenkörper 20 besitzt acht Arbeits- und Verbindungsflächen 32,33. Die Öffnungen 64,66,68 der Knotenkörper 18,20 sind so bemessen, daß die Verbindungsschrauben 22,24 durch die als Bohrungen ausgebildete Durchbrüche 40,42 von innen nach außen ohne weiteres einsteckbar sind. Insbesondere die Fig. 2 und 5 lassen erkennen, daR die Öffnungen 64,66,68 des Knotenkörpers 18,20 sich von außen nach innen verjüngen und daß die Deckel 70,72,74 im Verbindungsbereich komplementär zu den Knotenkörpern ausgebildet sind. Die Deckel 70,72,74 sind mit dem Knotenkörper 18,20 mittels Schrauben 80,82 verbindbar. Im Verbindungsbereich des Deckels 70 und des Knotenkörpers 18 ist ein Dichtungskörper 84 angeordnet. Eine dichte Verbindung zwischen dem Profilstab 12,16 und dem Knotenkörper 18,20 ist durch Dichtungsringe 90,92 hergestellt. Der Deckel 70 besitzt eine Bohrung 96,98 mit Gewinde, in das eine Brause bzw. eine Sprinklerdüse 98,100 einschraubbar ist.The ring-shaped or tubular node body 20 has eight working and connecting surfaces 32, 33. The openings 64, 66, 68 of the node body 18, 20 are dimensioned such that the Connecting screws 22, 24 can be easily inserted from the inside to the outside through the openings 40, 42 designed as bores. 2 and 5 in particular show that the openings 64, 66, 68 of the knot body 18, 20 taper from the outside inwards and that the covers 70, 72, 74 in the connection area are designed to be complementary to the knot bodies. The covers 70, 72, 74 can be connected to the node body 18, 20 by means of screws 80, 82. A sealing body 84 is arranged in the connection area of the cover 70 and the node body 18. A tight connection between the profile rod 12, 16 and the knot body 18, 20 is produced by sealing rings 90, 92. The cover 70 has a bore 96, 98 with a thread into which a shower or a sprinkler nozzle 98, 100 can be screwed.

Die Fig. 5 läßt ferner erkennen, daß Hohlprofilstäbe vorgesehen sind, deren Längsmittelachse die Arbeits- und Verbindungspartien unter einem von 90° verschiedenen Winkel schneiden. Um auch in solchen Fällen eine dichte und feste Verbindung zwischen dem Knotenkörper 20 und dem Hohlprofilstab 14 herstellen zu können, befindet sich zwischen dem im Innenraum des Knotenkörpers 20 angeordneten Kopf 102 der Verbindungsschrauben und dem Knotenkörper 20 eine Unterlegscheibe 104, die sich verjüngt, wobei der Neigungswinkel dieser Unerlegscheibe 104 dem Winkel entspricht, den die Längsmittelachse mit den Arbeits- und Verbindungspartien einschließt.5 also shows that hollow profile bars are provided, the longitudinal center axis of which intersect the working and connecting parts at an angle different from 90 °. In order to be able to establish a tight and firm connection between the knot body 20 and the hollow profile rod 14 in such cases, there is a washer 104 between the head 102 of the connecting screws arranged in the interior of the knot body 20 and the knot body 20, which tapers Inclination angle of this washer 104 corresponds to the angle which the longitudinal central axis includes with the working and connecting parts.

Der in Fig. 4 und 5 dargestellte ring- bzw. röhrenförmige Knotenkörper 18,20 weist acht äußere quadratische Anschlußflächen auf. Wie bei dem napfförmigen Knotenkörper (vgl. Fig. 1 bis 3) sind auch bei diesem Knotenkörper, die inneren Anschlußflächen quadratisch. Der Größenunterschied zwischen innerem und äußerem Quadrat wird durch einen stufenförmigen Absatz ausgeglichen. Die in den Arbeits- und Verbindungsflächen 32 ausgebildeten Bohrungen 92 (es sind jeweils zwei vorgesehen) ermöglichen nicht nur eine Verbindung des Knotenkörpers mit einem Stab 16, indem eine Schraube in Stab-Linksrichtung in einen entsprechenden Gewindekanal des Stabes 16 von innen eingedreht wird; sie erlauben auch die Verbindung der Knotenkörper 20 untereinander. Durch Einlegung einer achteckigen Scheibe oder auch eines achteckigen Bandes in die stufenförmige Vertiefung des Knotenrandes können mehrere bandförmige Knotenkörper in Profillängsrichtung miteinander verbunden werden. Der stufenförmige Rand des Knotenkörpers ermöglicht auf diese Weise auch die Verbindung eines napfförmigen mit einem ring- bzw. röhrenförmigen Knotenelement. Der stufenförmige Rand der ring- bzw. röhrenförmigen Knotenelemente kann auch durch das Ineinanderfügen zweier fünf-, sechs- oder achteckiger Profilstränge unterschiedlicher Schlüsselweite erzielt werden. Dabei können in einem der Profilstränge zylinderförmige Kanäle eingeprägt werden, in die selbstschneidende Schrauben eingreifen. Auf diese Weise erübrigt sich das Bohren und Gewindeschneiden zur Verbindung der ringförmigen Knotenkörper mit dem abdichtenden Deckel. Der stufenförmige Rand der Knotenelemente ermöglicht das Einlegen einer achteckigen Scheibe, die nicht nur die formschlüssige Verbindung der Knotenelemente in Profillängsrichtung erlaubt, sondern auch eine Aussteifung der ring- bzw. röhren- und napfförmigen Knoten bewirkt.The annular or tubular node body 18, 20 shown in FIGS. 4 and 5 has eight outer square connection surfaces. As in the case of the cup-shaped node body (cf. FIGS. 1 to 3), the inner connection surfaces are also square in this node body. The Difference in size between the inner and outer square is compensated for by a step-like heel. The bores 92 formed in the working and connecting surfaces 32 (two are provided in each case) not only enable the knot body to be connected to a rod 16 by screwing a screw in the rod left direction into a corresponding threaded channel of the rod 16 from the inside; they also allow the node bodies 20 to be connected to one another. By inserting an octagonal disc or an octagonal band in the step-shaped depression of the edge of the knot, several band-shaped knot bodies can be connected to one another in the longitudinal direction of the profile. The stepped edge of the knot body also enables the connection of a cup-shaped to an annular or tubular knot element. The step-shaped edge of the ring-shaped or tubular node elements can also be achieved by joining two pentagonal, hexagonal or octagonal profile strands of different width across flats. Cylindrical channels can be stamped into one of the profile strands, into which self-tapping screws engage. This eliminates the need for drilling and tapping to connect the annular knot bodies to the sealing lid. The step-like edge of the knot elements enables the insertion of an octagonal disc, which not only allows the positive connection of the knot elements in the longitudinal direction of the profile, but also stiffens the ring-shaped or tubular and cup-shaped knots.

Verwendet man für die Verbindung von Knotenkörpern und Stäben eine Schraube, die einen zylinderförmigen Hohlraum in Längsrichtung aufweist, entsteht auf einfachste Weise ein geschlossenes Rohrleitungsnetz, in dem Wasser und andere Medien geführt werden können. Diese Möglichkeit ist gerade bei Aluminiumtragwerken von entscheidender Bedeutung, da der Einsatz dieser Tragwerke häufig durch den bisher nicht vorhandenen Brandschutz ausgeschlossen wird. Das Rohrleitungsnetz ermöglicht nicht nur den passiven Brandschutz durch zirkulierendes Wasser; durch die Integration einer Sprinkleranlage in die tragende Struktur entsteht auf einfachste Weise eine aktiv arbeitende Feuerlöscheinrichtung. Die hohe Wärmeleitfähigkeit von Aluminium ermöglicht außerdem die Integration einer Heizung in das Tragwerk. Im Rahmen der Erfindung ist es auch möglich, etwa die Untergurtprofile eines Raumfachwerkes so auszubilden, daß Kunststoffprofile mit eingeschweißten Kupferbändern in das Tragprofil eingesetzt werden können und auf diese Weise an jeder beliebigen Stelle des Tragwerks eine Leuchte angeschlossen werden kann.If a screw is used to connect the knot bodies and rods, which has a cylindrical hollow space in the longitudinal direction, a closed pipeline network is created in the simplest way, in which water and others Media can be led. This option is particularly important for aluminum structures, since the use of these structures is often ruled out due to the lack of fire protection. The pipeline network not only enables passive fire protection through circulating water; The integration of a sprinkler system in the supporting structure creates an active fire extinguishing system in the simplest way. The high thermal conductivity of aluminum also enables a heater to be integrated into the structure. In the context of the invention, it is also possible, for example, to design the lower chord profiles of a space framework so that plastic profiles with welded copper strips can be inserted into the supporting profile and in this way a lamp can be connected at any point in the supporting structure.

In dem Hohlraum des Napfkörpers oder auch des ringförmigen Knotens kann die Verknüpfung der einzelnen Stromkreise erfolgen.The individual circuits can be linked in the cavity of the cup body or also of the ring-shaped node.

Die napf- oder auch ringförmige Ausbildung des Knotenkörpers eines Tragwerkes erlaubt das Eintragen der anfallenden Dachlasten direkt in das Obergurtprofil. Damit der Querkraftanteil dieser Lasten nicht durch die Verbindungsschraube von Stab und Knoten übertragen wird, kann ein hakenförmiges Element vorgesehen sein, das zwischen Knoten und Stab angeordnet ist und sich am stufenförmigen Rand des Knotens einhakt. Dieses Element verhindert auch ein Verdrehen der Stäbe. Handelt es sich um Knotenkörper, deren äußere Anschlußfläche nicht quadratisch, sondern rechteckig sind, dann erfolgt die Verbindung von Knoten und Stab durch zwei Schrauben. Auf diese Weise ist der Stab verdrehungssicher angeschlossen. Eine der beiden Schrauben kann wasserführend sein. Zusammen mit den beiden Deckeln, die über eine Dichtung den Hohlraum des Knotens abdichten, ist das bereits erwähnte Rohrleitungsnetz hergestellt.The bowl-shaped or ring-shaped design of the knot body of a supporting structure allows the roof loads to be entered directly into the upper chord profile. So that the lateral force component of these loads is not transmitted by the connecting screw of the rod and the knot, a hook-shaped element can be provided, which is arranged between the knot and the rod and hooks onto the step-shaped edge of the knot. This element also prevents the rods from twisting. If it is a knot body, the outer connection surface of which is not square, but rectangular, the knot and rod are connected by two screws. In this way, the rod is connected so that it cannot twist. One of the two Screwing can be water-bearing. Together with the two lids, which seal the cavity of the node via a seal, the pipeline network already mentioned is produced.

Schließlich lassen die Fig. 6, 7 und 8 erkennen, daß die Knotenkörper im Querschnitt regelmäßige Vielecke sind, die in ihrem Innenraum eingeprägte Gewindekanäle 83 für die Schrauben 82 besitzen.Finally, FIGS. 6, 7 and 8 show that the knot bodies are regular polygons in cross section, which have threaded channels 83 for the screws 82 stamped into their interior.
