Abstract

The invention relates to a framework construction having low weight, high rigidity and strength and of the kind comprising beams (11) in the form of tubes, which are interconnected by means of joints (21) to form a three-dimensional frame structure. The beams (11) in their basic shape consist of two tubes (13) connected to one another by means of a web (14), forming an I-beam (12). The beams (11), depending on load conditions and demands for rigidity, are assembled from several I-beams, forming L, U and/or box-profiles or combinations thereof. In order to form the frame structure, at least the tubes (13) of the beams are connected to each other through tube joints (21) at the ends of the beams and/or along the length of the beam in regions (22) designed therefore. The tube joints (21) are non-rotationally mounted to at least the tubes.

Beskrivning av ett utfóringsexempel Fackverkskonstruktionen enligt uppfinningen består av ett ramverk uppbyggt av balkprofiler 11, som kan vara I-, L-, U- eller lådprofiler, men även andra kombinationer är tänkbara. I sitt enklast utförande utgöres balken av en I-profil 12, där profilens “flänsar” 13 består av rör, t.ex. av kolfiber, aluminium, titan eller liknande material med låg vikt, och "livet" 14 utgöres av en sandwichstruktur, exempelvis uppbyggd av ett lämpligt kärnmaterial, t.ex. skummad PVC, och ett täckmaterial i form av exempelvis ett laminat, t.ex. kolfiber. Flänsarna 13 är kraftupptagande förbundna med livet 14 på lämpligt sätt i beroende av ingående material, t.ex. genom limning, svetsning, i samband med extrudering av profilen eller dylikt.Description of an exemplary embodiment The truss construction according to the invention consists of a framework built up of beam profiles 11, which can be I-, L-, U- or box profiles, but other combinations are also conceivable. In its simplest embodiment, the beam consists of an I-profile 12, where the profile's' nssens ”13 consist of pipes, e.g. of carbon fiber, aluminum, titanium or similar lightweight materials, and the "web" 14 consists of a sandwich structure, for example built of a suitable core material, e.g. foamed PVC, and a cover material in the form of, for example, a laminate, e.g. carbon fiber. The flanges 13 are force-absorbingly connected to the web 14 in a suitable manner depending on the constituent material, e.g. by gluing, welding, in connection with extrusion of the profile or the like.

Den enkla I-balken 12 kan sammansättas till ett flertal olika strukturer, beroende på vilka krav på styvhet och hållfasthet som ställes på fackverkskonstruktionen. L-balken 15 är således sammansatt av två I-balkar med en gemensam förbindelsepunkt - rör 16- mellan L-ets :open 517 '975 'f '* båda skänklar 17 och 18. På samma sätt är U-profilen 19 och lådprofilen 20 uppbyggd.The simple I-beam 12 can be assembled into a number of different structures, depending on the requirements for rigidity and strength that are placed on the truss construction. The L-beam 15 is thus composed of two I-beams with a common connection point - tube 16- between the L-ets: open 517 '975' f '* both legs 17 and 18. In the same way, the U-profile 19 and the box profile 20 structured.

Balkarna 12, 15, 19 och 20 kan “skräddarsys” och monteras till godtyckliga ramverk för olika tillämpningar. Balkama sammanfogas med hjälp av rörkopplingar 21 av typen grenkopplingar, varvid varje enskilt rör i de olika balkama kopplas samman till en fackverkskonstruktion. I fi g. 5 visas en hållare för ett föremål, som av en robot skall positioneras i ett bestämt läge för bearbetning i en automatiserad tillverkningsprocess eller montering vid exempelvis ett chassi inom fordonsindustrin. Rörkopplingarna 21 kan lämpligen vara av två slag, en typ som träs på rören från ändama och en typ som är delade, för att kunna monteras på godtyckligt ställe längs något av rören. I sistnämnda fall anordnas en urtagning 22 i livet 14, där den delade rörkopplingen 21 skall anbringas. Rörkopplingarna finns åtminstone i de vanligast förekommande vinklar, 15, 30, 45 och 90 grader samti form av knutpunktskopplingar 23, för sammankoppling av flera tex. fyra korslagda balkar.The beams 12, 15, 19 and 20 can be "tailored" and mounted to arbitrary frameworks for different applications. The beams are joined by means of pipe couplings 21 of the branch couplings type, each individual pipe in the various beams being connected together into a truss construction. Fig. 5 shows a holder for an object which is to be positioned by a robot in a specific position for processing in an automated manufacturing process or assembly at, for example, a chassis in the automotive industry. The pipe couplings 21 can suitably be of two types, a type which is threaded on the pipes from the ends and a type which are divided, in order to be able to be mounted in any place along one of the pipes. In the latter case, a recess 22 is provided in the web 14, where the divided pipe coupling 21 is to be fitted. The pipe couplings are available at least in the most common angles, 15, 30, 45 and 90 degrees and in the form of hub couplings 23, for interconnection of several e.g. four crossed beams.

Rörkopplingama förbindes vridfast med respektive rör 13 medelst lim-, svets- eller kläm- förband eller liknande.The pipe couplings are connected in a rotationally fixed manner to the respective pipe 13 by means of glue, welding or clamping joints or the like.

Utföringsexemplet enligt fig. 5 och 6 åskådliggör en fackverkskonstruktion i form av ett ramverk, som bildar en hållare 24, även kallad grimma, för en konstruktionsdetalj (ej visad), vilken skall bearbetas eller monteras i en annan konstruktionsdetalj. Hållaren 24 är utformad med en central knutpunktskoppling 23, som även bildar fäste för en robotarm. Knutpunkts- kopplingen 23 förbinder fyra korslagda I-balkar 25, vars yttre ändpartier är sammankopplade med ett rektangulärt ramverk bestående av mittemot belägna I-balkar 26 och 27 och tvärs mot dessa anordnade L-balkar 28 och 29. På balkama är anordnade fästen 30, för fasthållning av konstruktionsdetaljen i fråga. Vid balkarnas 25 fria ändar är anordnade fästen 31för positio- nering av hållaren relativt fasta referenspunkter. Mellan balkama kan vara anordnade förstyv- ningssträvor 32 i form av enkla rör, vid vilka även kan vara anbragta ytterligare fästen. l det visade utföringsexemplet är ramverkets balkar 26, 27 och 28,29 belägna på olika nivåer, men det är givetvis möjligt att utforma grenkopplingar 21 för anslutning av fler än två rör, tex tre eller fyra, vilka dessutom kan ha olika vinklar. 517.975 Det kan i vissa sammanhang vara lämpligt att i en knutpunkt inte enbart förbinda rören 13 med varandra, utan även liven 14, så som är visad i fig. 6. Rörkopplingarna 21 kan även utformas så, att både rören 13 och livet 14 kan skjutas in i dessa, så att en effektiv förbindelse av hela balken åstadkommes.The exemplary embodiment according to Figs. 5 and 6 illustrates a truss construction in the form of a framework, which forms a holder 24, also called a halter, for a construction detail (not shown), which is to be machined or mounted in another construction detail. The holder 24 is formed with a central node coupling 23, which also forms a bracket for a robot arm. The junction coupling 23 connects four crossed I-beams 25, the outer end portions of which are connected by a rectangular framework consisting of opposite I-beams 26 and 27 and transversely arranged L-beams 28 and 29. On the beams are arranged brackets 30, for holding the construction detail in question. At the free ends of the beams 25, brackets 31 are arranged for positioning the holder relatively fixed reference points. Stiffening struts 32 can be arranged between the beams 32 in the form of simple pipes, to which additional brackets can also be arranged. In the exemplary embodiment shown, the beams 26, 27 and 28, 29 of the framework are located at different levels, but it is of course possible to design branch connections 21 for connecting more than two pipes, for example three or four, which can also have different angles. 517,975 In some contexts it may be convenient to connect not only the tubes 13 to each other at a junction, but also the webs 14, as shown in Fig. 6. The tube couplings 21 can also be designed so that both the tubes 13 and the web 14 can be pushed into these, so that an efficient connection of the whole beam is achieved.
