Description

Sveiset hjørneforbindelse av lettmetall-profiler. Welded corner connection of light metal profiles.

Foreliggende oppfinnelse angår en hjorneforbindelse av lettmetall-profiler, hvis ender er gjæret. En slik hjorneforbindelse er særlig The present invention relates to a corner connection of light metal profiles, the ends of which are mitered. Such a corner connection is special

egnet for konstruksjoner av rammeelement-bæreprofiler. suitable for constructions of frame element bearing profiles.

Ved oppstilling av byggverk i stillasform blir det som oftest benyttet rammeelementer av metall, idet det tidligere utelukkende ble benyttet Jern og stål mens det nå mer og mer benyttes lettmetall. Stolper og dragere har vanligvis T- eller dobbelt-T-tverrsnitt. When erecting structures in scaffolding form, frame elements made of metal are most often used, as previously only iron and steel were used, while now more and more light metal is used. Posts and girders usually have a T or double-T cross-section.

Ved stillasbygging er rammehjbrnene en vesentlig del av konstruksjonen da her både boyemomenter og trykk-krefter må overfores fra et element til et annet. Opp til nå har det også i lettmetallkonstruk-sjoner vært benyttet konstruksjonsmåter kjent fra stålkonstruksjoner, f.eks. fastsveising, nagling eller skruing av lasker som muliggjor tilslutning til flensene. Disse lasker anordnes over eller under flensene, 'er synlige, rager frem fra rammesidens alminnelige plan, virker derfor lite pene og er til hinder når det skal anbringes forskalinger eller andre elementer mot rammen. Overforingen av påkjenninger skjer som regel gjennom sveisesbmmer, henhv. nagle- eller skrue-rekker som ligger på tvers av stolper og dragere. Alt etter påkjenningen må det i rammehjbrnene anordnes ytterligere ribber eller stegplater som overtar en del av trykkoverfbringen. In scaffolding construction, the frame supports are an essential part of the construction as here both bending moments and compressive forces must be transferred from one element to another. Up until now, construction methods known from steel structures have also been used in light metal constructions, e.g. welding, riveting or screwing of tabs that enable connection to the flanges. These flaps are arranged above or below the flanges, are visible, protrude from the general plane of the frame side, therefore look unattractive and are an obstacle when formwork or other elements are to be placed against the frame. The transfer of stresses usually takes place through welding beams, respectively. rows of rivets or screws that lie across posts and girders. Depending on the stress, additional ribs or stepped plates must be arranged in the frame supports which take over part of the pressure transfer.

Disse forbindelsesmåter, som er betinget av bearbeidelsesegenskapene for stål, er imidlertid forholdsvis komplisert, krever meget arbeid og motvirker derfor bestrebelsene for oppnåelse av en rasjonell frem-stilling av en hurtig montering. Dertil kommer at lbperetningen for de sveisesbmmer som er anordnet på tvers av stolper og dragere ikke er gunstig for de påkjenninger som oppstår i rammen. However, these connection methods, which are conditioned by the processing properties of steel, are relatively complicated, require a lot of work and therefore counteract the efforts to achieve a rational production of a rapid assembly. In addition, the direction of operation of the welding beams which are arranged across posts and beams is not favorable for the stresses that occur in the frame.

Den sveisede hjorneforbindelse i henhold til foreliggende oppfinnelse overvinner de foran nevnte ulemper og utnytter de bedre bearbeidelses-egenskaper som aluminium og legeringer derav har, hvormed det vil kunne strengpresses forholdsvis kompliserte profiltverrsnitt. The welded corner connection according to the present invention overcomes the disadvantages mentioned above and utilizes the better processing properties that aluminum and its alloys have, with which relatively complicated profile cross-sections can be extruded.

Hjorneforbindelsen i henhold til oppfinnelsen sammenstilles på en enkel måte av få deler og muliggjor anbringelse av de nbdvendige sveisesbmmer slik at den mekaniske styrke i hjbrnet ikke nedsettes. Også når det gjelder påmontering av andre elementer, henhv. den estetiske virkning betyr konstruksjonen en forbedring da forbindelses-elementene i det vesentligste forsvinner i det indre av rammen. The corner connection according to the invention is assembled in a simple way from a few parts and enables the placement of the necessary welding beams so that the mechanical strength of the corner is not reduced. Also when it comes to mounting other elements, respectively the aesthetic effect means an improvement to the construction as the connection elements essentially disappear in the interior of the frame.

Det særegne ved den sveisede hjorneforbindelse i henhold til oppfinnelsen fremgår av krav 1. The peculiarity of the welded corner connection according to the invention appears in claim 1.

De rammelignende lettmetallprofiler som omfatter hjorneforbindelser i henhold til foreliggende oppfinnelse egner seg særlig for vegger, men kan også benyttes for gulv og tak. I det sistnevnte tilfelle omfatter rammen ikke stolper men bare horisontale bjelker. I begge tilfeller er imidlertid hjorneforbindelsen i henhold til oppfinnelsen i praksis den samme. The frame-like light metal profiles which include corner connections according to the present invention are particularly suitable for walls, but can also be used for floors and ceilings. In the latter case, the frame does not include posts but only horizontal beams. In both cases, however, the corner connection according to the invention is practically the same.

Oppfinnelsen skal nærmere beskrives under henvisning til vedfoyde tegning som viser en foretrukket utfbrelsesform. Fig. 1 viser de enkelte deler av eh rettvinklet hjorneforbindelse, forut for sammenstilling. The invention shall be described in more detail with reference to the attached drawing which shows a preferred embodiment. Fig. 1 shows the individual parts of eh right-angled corner connection, prior to assembly.

Fig. 2 viser den ferdige hjorneforbindelse. Fig. 2 shows the finished corner connection.

På tegningen betegner 1 den ende av et stolpeprofil som vender mot In the drawing, 1 denotes the end of a post profile that faces

et rammehjbrne, og 2 betegner den tilsvarende ende av et dragerprofil. For forenkling av fabrikasjon og lagerhold er begge profiler i dette eksempel utfort med utformnlngsmessig og dimensjonsmessig det samme dobbelt-T-tverrsnitt. For begge profiler er steget betegnet 3» Flensene k- i hvert profil 1 og 2 består hver av i tverrsnitt en T-formet del 5 og en renneformet del 6 hvis lengdekanter sammen med delen 5 danner to underskårne spor 7 i flensene h. For bedre klar-gjøring er på tegningen to av flensene k- innsirklet. 8 betegner et hjorneforbindelsesstykke som består av en firkantet stegplate 9 og åtte festestaver 10 som i områdene nær endekantene 12 og 13 på stegplaten rager ut i ^-5° med denne mot stolpen 1 og drageren 2. Ved sammenstilling av elementene som danner hjorneforbindelsen blir disse staver 10 fort fullstendig inn i de underskårne spor 7 i stolpe og drager. Stbrrelsen og utformningen av stegplaten 9 bestemmes av den firkant som avgrenses av de skråskårne endeflater på stolpe- og drager-profilene. a frame support, and 2 denotes the corresponding end of a girder profile. To simplify manufacturing and stocking, both profiles in this example are made with the same double-T cross-section in terms of design and dimensions. For both profiles, the pitch is designated 3". The flanges k- in each profile 1 and 2 each consist of a T-shaped part 5 in cross section and a channel-shaped part 6 whose longitudinal edges together with the part 5 form two undercut grooves 7 in the flanges h. For better preparation, two of the flanges are circled in the drawing. 8 denotes a corner connection piece consisting of a square step plate 9 and eight fastening rods 10 which, in the areas near the end edges 12 and 13 of the step plate, protrude at ^-5° with this towards the post 1 and the beam 2. When assembling the elements that form the corner connection, these rods 10 fast completely into the undercut grooves 7 in the post and beams. The size and design of the step plate 9 is determined by the square delimited by the beveled end surfaces of the post and girder profiles.

Fortrinnsvis er sideveggende på den U-formede del 6 av flensen h omboyet i rett vinkel ved 11 mot den T-formede del 5 av flensen, hvorved det dannes spor 7 som er underskåret på begge sider. Dette hjelper til å hindre at festestavene 10, ved bbyepåkjenninger i stolpe- og drager-profilene, trykkes ut av sporene 7. Ombbyningen av kanten på sideveggende ved 11 er imidlertid ikke ubetinget nbdvendig. Det kan også benyttes profiler med langsgående spor uten under-skjæring, men det kreves da mere sveisesbm. Preferably, the side walls of the U-shaped part 6 of the flange are curved at right angles at 11 to the T-shaped part 5 of the flange, whereby a groove 7 is formed which is undercut on both sides. This helps to prevent the fastening rods 10 from being pushed out of the grooves 7 by bending stresses in the post and girder profiles. However, the remodeling of the edge on the side wall end at 11 is not absolutely necessary. Profiles with longitudinal grooves without undercutting can also be used, but more welding power is then required.

Generelt sagt. er de langsgående spor hensiksmessig underskåret på minst en side og fortrinnsvis på begge sider. Generally speaking. the longitudinal grooves are suitably undercut on at least one side and preferably on both sides.

Av estetiske årsaker kan det være onskelig å avskråne den ytre endeside 12 på stegplaten 9 på begge sider slik at de avskrånede flater kommer i flukt med overflaten på de ytre flenser h. Av tilsvarende årsaker kan den indre ende 13 av stegplaten være utformet med en rille. For aesthetic reasons, it may be desirable to bevel the outer end side 12 of the step plate 9 on both sides so that the beveled surfaces come flush with the surface of the outer flanges h. For similar reasons, the inner end 13 of the step plate can be designed with a groove .

Fortrinnsvis tilsvarer tverrsnittet på samtlige festestaver 10 tverrsnittet av sporene 7 på en slik måte at det etter innforing av stavene ikke er noen klaring mellom sideflatene på stavene 10 og veggene i sporene 7 hvorved det fås et godt feste av stavene i sporene. Preferably, the cross-section of all fastening rods 10 corresponds to the cross-section of the grooves 7 in such a way that, after inserting the rods, there is no clearance between the side surfaces of the rods 10 and the walls of the grooves 7, whereby a good fastening of the rods in the grooves is obtained.

Etter innforing i sporene 7 sveises stavene 10 fast til kantene på sporene, fortrinnsvis over hele stavlengden. Sveisesbmmene ligger i lengderetningen av stolpe- og drager-profilene og sikrer en bedre overforing av påkjenninger og dermed en bedre mekanisk styrke i hele hjorneforbindelsen enn tilfellet er med tversgående sveisesbmmer. Dertil blir stegplaten 9 sveiset til de gjærete endeflater på stolpe-og drager-profilene, og fortrinnsvis bare mellom stegplaten 9 og stegene 3i hvorved selve sveisearbeidet forenkles og allikevel en fullstendig tilstrekkelig sterk forbindelse oppnås. After insertion in the grooves 7, the rods 10 are welded firmly to the edges of the grooves, preferably over the entire rod length. The welding beams lie in the longitudinal direction of the post and girder profiles and ensure a better transfer of stresses and thus a better mechanical strength in the entire corner connection than is the case with transverse welding beams. In addition, the step plate 9 is welded to the mitered end surfaces of the post and girder profiles, and preferably only between the step plate 9 and the steps 3i, whereby the welding work itself is simplified and yet a completely sufficiently strong connection is achieved.

I det viste utfbrelseseksempél er sporene 7 anordnet på utsiden av flensene k. Det er imidlertid mulig å anordne dem på innsiden av flensene men i et slikt tilfelle vil sveisearbeidet være vanskeligere og overforingen av momentet i hjbrnet vil frembringe stbrre spenninger i sveisesbmmene. Endelig kan sporene også være anordnet på sidekantene av flensene <*>+. In the embodiment shown, the grooves 7 are arranged on the outside of the flanges k. It is, however, possible to arrange them on the inside of the flanges, but in such a case the welding work will be more difficult and the transfer of the moment in the corner will produce greater stresses in the welding beams. Finally, the grooves can also be arranged on the side edges of the flanges <*>+.

Den nbdvendige lengde av hver festestav 10 beregnes ved spennings-analyse. The required length of each fastening rod 10 is calculated by stress analysis.

Tverrsnittsflaten for en hvilken som helst av flensene tilsvarer omtrent summen av tverrsnittsflåtene for de festestaver som er fort inn i sporene i vedkommende'flens. Ved den utfbrelsesform som er vist i fig. 1 og 2 tilsvarer tverrsnittsflaten av en av flensene h omtrent det dobbelte av tverrsnittsflaten for hver enkelt festestav 10, idet jo to festestaver er fort inn i hver flens. The cross-sectional area of any one of the flanges corresponds approximately to the sum of the cross-sectional areas of the fastening rods which are fast into the grooves of the flange in question. In the embodiment shown in fig. 1 and 2, the cross-sectional area of one of the flanges h corresponds to approximately twice the cross-sectional area of each individual fastening rod 10, as two fastening rods are inserted into each flange.

Dobbelt-T-profilene fremstilles fordelaktig av en aluminiumlegering, fortrinnsvis ved strengpressing av legeringen i form av AlZnMg i overensstemmelse med tyske normer (M—5 % Zn, 0,8-1,6 io Mg, resten Al), hvilken legering egner seg særlig for sveisede konstruksjoner. The double-T profiles are advantageously produced from an aluminum alloy, preferably by extrusion of the alloy in the form of AlZnMg in accordance with German standards (M—5% Zn, 0.8-1.6 io Mg, the rest Al), which alloy is suitable especially for welded constructions.

Av hensyn til den mekaniske styrke blir hjorneforbindelsesstykket fordelaktig fremfremstilt av den samme AlZnMg-legering. Det kan eksempelvis fremstilles ved utskjæring fra et strengpresset profil hvor det overflbdige material bortfreses, eller det kan fremstilles ved formstbping. For reasons of mechanical strength, the corner connecting piece is advantageously produced from the same AlZnMg alloy. It can, for example, be produced by cutting from a string-pressed profile where the excess material is milled away, or it can be produced by mould-casting.

Rammekonstruksjoner med hjorneforbindelser i henhold til oppfinnelsen er, sammenlignet med tidligere kjente konstruksjoner, enklere i frem-stilling av de enkelte elementer og enklere i montering, samt kan leveres monteringsklar til taonteringsstedet. Frame constructions with corner connections according to the invention are, compared to previously known constructions, simpler to manufacture the individual elements and easier to assemble, and can be delivered ready for assembly to the installation site.

Forsbk har vist at hjorneforbindelsen i henhold til oppfinnelsen tåler alle de betingelser som settes når det gjelder mekanisk styrke. Hjbrneforbindelsen egner seg særlig for seriefremstilling av boliger og andre bygninger. Forsbk has shown that the corner connection according to the invention withstands all the conditions set in terms of mechanical strength. The Hjbrne connection is particularly suitable for serial production of homes and other buildings.
