Abstract

A carcase (1) is firstly manufactured by arranging a plurality of elongate members (4) of a composite material around a plurality of spacer members (2). A plurality of taut wires (5, 5') is subsequently wound around the carcase (1) such that each elongate member (4) is contacted by one of the wires (5, 5') in the plane of each spacer member (2). The wires (5, 5') may be subsequently adhered to the carcase (1), preferably by means of melting a thermoplastics coating of the wires (5, 5') and allowing the coating to set. The beam produced by this method is lightweight and strong.

Description

Fremgangsmåte for fremstilling av en fagverksbjelke. Procedure for manufacturing a truss beam.

Foreliggende oppfinnelse vedrører en fremgangsmåte for å fremstille en fagverksbjelke. The present invention relates to a method for producing a truss beam.

Fagverksbjelker er vanligvis fremstilt av enten stål eller komposittmateriale. Stålbjelker er sterke, men er meget tunge og derfor ubekvemme å håndtere. Sammenlignbart sterke bjelker av komposittmateriale lages i seksjoner ved bruk av et verktøy, noe som uvilkårlig øker fremstillingsomkostning-ene. Videre har slike bjelker av komposittmateriale store massive tverrsnitt, noe som medfører at bjelkene blir tunge på en ikke ønskelig måte. Oppfinnelsen søker å tilveie-bringe en sterk fagverksbjelke med lav vekt, som er enkel og billig å fremstille. Truss beams are usually made from either steel or composite material. Steel beams are strong, but are very heavy and therefore inconvenient to handle. Comparably strong beams of composite material are made in sections using a tool, which indiscriminately increases the manufacturing costs. Furthermore, such beams of composite material have large massive cross-sections, which causes the beams to become undesirably heavy. The invention seeks to provide a strong truss beam with a low weight, which is simple and cheap to manufacture.

Oppfinnelsen tilveiebringer en fremgangsmåte for fremstilling av en fagverksbjelke som erkarakterisert vedfølgende trinn: a) fremstille en stamme innbefattende en flerhet langstrakte organer som er adskilt av en flerhet plane avstandselementer; og b) deretter vikle en flerhet spente, fleksible elementer rundt stammen på en slik måte at hvert langstrakt organ er i The invention provides a method for manufacturing a truss beam which is characterized by the following steps: a) manufacturing a trunk including a plurality of elongated members which are separated by a plurality of planar spacing elements; and b) then wrapping a plurality of tensioned flexible members around the trunk in such a manner that each elongate member is in

kontakt med ett av de fleksible elementer i planet for hvert avstandselement og derved holdes på plass. contact with one of the flexible elements in the plane for each distance element and thereby held in place.

Fortrinnsvis er noen av de fleksible elementer viklet rundt stammen slik at avstandselementenes kanter er i kontakt med en del av nevnte fleksible elementer mellom inntil hverandre liggende langstrakte organer. Preferably, some of the flexible elements are wound around the stem so that the edges of the spacer elements are in contact with a part of said flexible elements between adjacent elongated bodies.

Fortrinnsvis er hvert fleksible element festet til stammen på hvert kontaktpunkt mellom disse. Preferably, each flexible element is attached to the stem at each point of contact therebetween.

Fortrinnsvis er de langstrakte organer rørformede. Preferably, the elongate members are tubular.

Fortrinnsvis er de langstrakte organer av et komposittmate riale som innbefatter herdbar plast eller termoplast og fibre. Preferably, they are elongate members of a composite material which includes curable plastic or thermoplastic and fibres.

Fortrinnsvis er de anvendte materialer valgt slik at deres elastisitetsmoduler, Poisson's tall og densiteter har verdier av samme størrelsesorden. Preferably, the materials used are chosen so that their modulus of elasticity, Poisson's number and density have values of the same order of magnitude.

Fortrinnsvis er de benyttede materialer valgt slik at de har elastisitetsmoduler, Poisson's tall og densiteter med til-nærmet samme verdi. Preferably, the materials used are chosen so that they have elastic moduli, Poisson's numbers and densities with approximately the same value.

Fortrinnsvis er hvert fleksibelt element av elektrisk ledende materiale og har fortrinnsvis et overflatebelegg av et termoplastisk materiale. Preferably, each flexible element is of electrically conductive material and preferably has a surface coating of a thermoplastic material.

Fortrinnsvis er de fleksible elementer innrettet til å festes til stammen ved at en elektrisk strøm sendes gjennom dem. Preferably, the flexible elements are adapted to be attached to the stem by passing an electric current through them.

Rommet mellom de langstrakte organer i en bjelke fremstilt ifølge fremgangsmåten beskrevet ovenfor gjør det mulig å fremstille en bjelke med lav masse pr. lengdeenhet. De fleksible elementer er i kontakt med de langstrakte organer i hvert avstandselements plan for å presse de langstrakte organer mot avstandselementene og opprettholde god kontakt mellom dem. Den således fremstilte bjelke opptrer da som en eneste enhet for mekaniske formål: de fleksible elementer opptar hoveddelen av alle påkjenninger som bjelken utsettes for. Denne er derfor sterk og har lav vekt. Den kan også fremstilles i passende lengder istedenfor i seksjoner. The space between the elongated members in a beam produced according to the method described above makes it possible to produce a beam with a low mass per unit of length. The flexible members are in contact with the elongate members in the plane of each spacer to press the elongate members against the spacers and maintain good contact between them. The beam produced in this way then acts as a single unit for mechanical purposes: the flexible elements absorb the main part of all stresses to which the beam is subjected. This is therefore strong and has a low weight. It can also be produced in suitable lengths instead of in sections.

En utførelse av oppfinnelsen er vist på vedføyede tegning, hvor: Fig. 1 er et perspektivisk riss av tre avstandselementer anordnet langs et rør eller en aksel; Fig. 2 er et perspektivisk riss av en stamme som innbefatter avstandselementene og akselen ifølge fig. 1 og dertil rør anordnet på en forutbestemt måte; Fig. 3 er et perspektivisk riss av stammen på fig. 2 med en første tråd viklet rundt rørene; og Fig. 4 er et perspektivisk riss av stammen ifølge fig. 3 med en andre tråd viklet rundt rørene. An embodiment of the invention is shown in the attached drawing, where: Fig. 1 is a perspective view of three spacer elements arranged along a pipe or an axle; Fig. 2 is a perspective view of a trunk which includes the distance elements and the shaft according to fig. 1 and thereto pipes arranged in a predetermined manner; Fig. 3 is a perspective view of the stem in fig. 2 with a first thread wrapped around the tubes; and Fig. 4 is a perspective view of the trunk according to fig. 3 with a second thread wrapped around the tubes.

Som det fremgår av tegningen, begynner fremgangsmåten ifølge oppfinnelsen med fremstilling av stammen 1. Avstandselementer 2 av et komposittmateriale av glassfiber og en termoplast er plassert med lik innbyrdes avstand langs en aksel eller et rør 3. Akselen eller røret 3 er anordnet på et vertikalt roterbart dreiebord for å øke adkomsten til bjelken under fremstillingen. Langstrakte organer i form av rør 4, som likeledes består av et lignende komposittmateriale, anordnes deretter i forutbestemte stillinger i forhold til avstandselementene 2. As can be seen from the drawing, the method according to the invention begins with the production of the trunk 1. Spacer elements 2 of a composite material of glass fiber and a thermoplastic are placed at equal distances from each other along a shaft or a pipe 3. The shaft or pipe 3 is arranged on a vertically rotatable turntable to increase access to the beam during manufacture. Elongated organs in the form of tubes 4, which likewise consist of a similar composite material, are then arranged in predetermined positions in relation to the spacer elements 2.

En flerhet tråder 5 vikles deretter ifølge et forutbestemt mønster rundt stammen 1. Dette mønster kan være et spiral-mønster. Hvert rør 4 er i kontakt med en tråd 5 i hvert avstandselements 2 plan. Kantene av hvert avstandselement 2 krysses av en tråd 5 mellom inntilliggende rør 4. Ytterligere tråder 5' påvikles deretter for å øke stabiliteten og styrken av bjelken. De ytterligere tråder 5' vikles også i et spiralmønster, fortrinnsvis roterende i motsatt retning i forhold til de første tråder 5. De ytterligere tråder 5<1>er også i kontakt med rørene 4 i hvert avstandselements 2 plan, og avstandselementenes 2 kanter krysses alle av en tråd 5' A plurality of threads 5 are then wound according to a predetermined pattern around the stem 1. This pattern can be a spiral pattern. Each tube 4 is in contact with a thread 5 in the plane of each spacer element 2. The edges of each spacer element 2 are crossed by a wire 5 between adjacent pipes 4. Additional wires 5' are then wound to increase the stability and strength of the beam. The further threads 5' are also wound in a spiral pattern, preferably rotating in the opposite direction to the first threads 5. The further threads 5<1> are also in contact with the tubes 4 in the plane of each spacer element 2, and the edges of the spacer elements 2 all cross of a strand 5'

mellom inntil hverandre liggende rør 4.between adjacent pipes 4.

Hver tråd 5, 5' har en kjerne av elektrisk ledende materiale og et overflatebelegg av et termoplastisk materiale. Trådene 5, 5<1>bringes til å hefte til stammen 1 ved at man lar en strøm passere gjennom kjernen slik at det termoplastiske belegg smelter. Komposittmaterialets termoplastiske plast i rørene 4 og avstandselementene 2 smelter også i det område som ligger rundt hvert kontaktpunkt med trådene 5, 5'. Når strømmen slås av og trådene 5, 5' kjølner, stivner termoplasten og forbinder trådene 5, 5<1>med rørene 4 og avstandselementene 2. Each wire 5, 5' has a core of electrically conductive material and a surface coating of a thermoplastic material. The threads 5, 5<1> are brought to adhere to the stem 1 by allowing a current to pass through the core so that the thermoplastic coating melts. The thermoplastic plastic of the composite material in the tubes 4 and the spacers 2 also melts in the area around each point of contact with the threads 5, 5'. When the current is switched off and the threads 5, 5' cool, the thermoplastic hardens and connects the threads 5, 5<1> with the tubes 4 and the spacers 2.

Selv om de langstrakte organer, som beskrevet ovenfor, er rørformede, kunne det være like akseptabelt å benytte massive stenger av relativt lett konstruksjon og rørformede organer fylt med skum eller syntetisk materiale. Forskjel-lige arrangementer av de langstrakte organer rundt avstandselementene er mulige idet arrangementet som er vist på tegningen kun skal anses som et eksempel. Oppfinnelsen er heller ikke begrenset til langstrakte organer av komposittmateriale - det er åpenbart at langstrakte organer av tynn-veggede stål- eller aluminiumsrør også ville kunne egne seg. Although the elongate members, as described above, are tubular, it could be equally acceptable to use solid rods of relatively light construction and tubular members filled with foam or synthetic material. Various arrangements of the elongate bodies around the spacer elements are possible, the arrangement shown in the drawing only being considered as an example. The invention is also not limited to elongate members of composite material - it is obvious that elongate members of thin-walled steel or aluminum tubes would also be suitable.

De fleksible elementer kan være tråder, liner eller bånd av stål eller annet metall, eller de kan utgjøres av ikke-metalliske materialer med høy strekkfasthet såsom kullfiber-eller glassfiberarmert plast. De fleksible elementer kan ha et overflatebelegg av et plastisk materiale og kan festes til stammen på annen måte enn den som er beskrevet ovenfor, f.eks. ved direkte tilførsl av varme til det termoplastiske overflatebelegg. Alternativt kan de fleksible elementer festes til stammen ved hver ende av bjelken eller ved perio-diske intervaller. Befestigelsen kan utføres på en hvilken som helst passende måte, f.eks. ved binding, sveising eller gjentatt vikling. Andre mønstre enn spiraler kan benyttes forutsatt at de langstrakte organer er i kontakt med de fleksible elementer i hvert avstandselements plan. The flexible elements can be threads, lines or bands of steel or other metal, or they can be made of non-metallic materials with high tensile strength such as carbon fiber or glass fiber reinforced plastic. The flexible elements can have a surface coating of a plastic material and can be attached to the stem in a different way than that described above, e.g. by direct application of heat to the thermoplastic surface coating. Alternatively, the flexible elements can be attached to the trunk at each end of the beam or at periodic intervals. The fastening can be carried out in any suitable way, e.g. by binding, welding or repeated winding. Patterns other than spirals may be used provided that the elongate members are in contact with the flexible elements in the plane of each spacer element.

En passende termoplast som kan benyttes for de langstrakte organer og overflatebelegget på trådene er det som i Sverige er kjent som "Aramid". Nylon kan også benyttes. Disse er kun nevnt som eksempler. A suitable thermoplastic that can be used for the elongated members and the surface coating on the threads is what is known in Sweden as "Aramid". Nylon can also be used. These are only mentioned as examples.

Det vil forstås at et enkelt fleksibelt element henviser til en tråd eller lignende som løper fra den ene ende av bjelken til den andre. Det ville naturligvis være mulig å benytte etter hverandre viklede fleksible elementer som ble forbundet ende mot ende og viklet frem og tilbake langs bjelken. It will be understood that a single flexible element refers to a wire or the like that runs from one end of the beam to the other. It would of course be possible to use successively wound flexible elements which were connected end to end and wound back and forth along the beam.
