Description
Foreliggende oppfinnelse angår et forbindelseselement ifølge kravinnledningen. The present invention relates to a connecting element according to the preamble.
Store rammekonstruksjoner som især benyttes for boreplattformer, settes sammen av forbindelseselementer som mellom seg omfatter i et plan eller flate kryssende dragere 1 og et i rett vinkel til en eller to sider ført rør 2. Large frame constructions, which are especially used for drilling platforms, are assembled from connecting elements which between them comprise in a plane or flat intersecting girders 1 and a pipe 2 led at right angles to one or both sides.
Dragerne ligger i regelen i horisontalt plan og har vanligvis et tverrsnitt tilsvarende en dobbelt-T. Røret står vertikalt og tjener som støtte. As a rule, the girders lie in a horizontal plane and usually have a cross-section corresponding to a double-T. The pipe stands vertically and serves as a support.
Fra GB 1 30Jt 352 er en forbindelse kjent med i to i rett vinkel til hverandre liggende plan anordnede, rørformede dragere med et knute- hhv. forbindelseselement. Forbindelsesele-mentet består av et kuppelformet legeme viss kant ligger an mot et rørs ende og er sveist til dette og viss andre side omfatter ribbeformede deler viss ytre kanter ligger an mot og er sveist til det andre rør. From GB 1 30Jt 352, a connection is known with two flat, tubular girders lying at right angles to each other with a knot or connecting element. The connecting element consists of a dome-shaped body, one edge of which rests against the end of a pipe and is welded to it, and the other side comprises rib-shaped parts, while the outer edges rest against and are welded to the other pipe.
Videre er det fra DE-Z Stahl und Eisen 73 1953, Heft 9, 556-567 for sveisekonstruksjoner kjent å utforme et forbindelses-elements tilkoplingsende for forbindelsen av kryssende ståldragere med dobbelt T-tverrsnitt, slik at de er tilpasset dragernes profil. Furthermore, it is known from DE-Z Stahl und Eisen 73 1953, Heft 9, 556-567 for welding constructions to design the connection end of a connecting element for the connection of crossing steel girders with a double T cross-section, so that they are adapted to the profile of the girders.
Det er også kjent å sveise drageren direkte til røret med de ender som støter mot røret. For at den kryssende forbindelse av rør og drager også skal kunne overføre større krefter og bøyemomenter, er det videre kjent å benytte et relativt kort rør med tykk vegg i krysningsområdet, til hvilket det som støtte tjenende rør med vesentlig tynnere vegg, er sveist. It is also known to weld the girder directly to the pipe with the ends butting against the pipe. In order for the crossing connection of pipes and girders to also be able to transmit greater forces and bending moments, it is also known to use a relatively short pipe with a thick wall in the crossing area, to which the supporting pipe with a significantly thinner wall is welded.
Denne kjente utforming har den ulempe at sveisesømmene for så ulike materialtykkelser kan støte mot hverandre, noe som kan gjøre sveisingen ytterst vanskelig. På den annen side kan ikke rørets veggtykkelse i krysningsområdet dimensjoneres mindre, da det eller ville oppstå for liten styrke i knutepunktet. This known design has the disadvantage that the welding seams for such different material thicknesses can collide with each other, which can make welding extremely difficult. On the other hand, the pipe's wall thickness in the crossing area cannot be dimensioned smaller, as there would be too little strength at the junction.
Når det av statiske grunner kreves en tykkelse på ca. 60 mm eller mer, er det vanlig å sveise fast avstivninger inne i røret. Imidlertid er også disse likeledes sveiseteknisk ugunstig og relativt omstendelige på grunn av spenningsforholdene i rommet. When a thickness of approx. 60 mm or more, it is common to weld stiffeners inside the pipe. However, these are also unfavorable from a welding point of view and relatively cumbersome due to the tension conditions in the room.
Oppfinnelsen tar sikte på å modifisere denne konstruksjon som er begrenset av dimensjonene og sveiseteknikken, ved bruk av stålstøpegods slik at både store bøyemomenter og trykkrefter kan* overføres og sveiseforbindelsene kan reduseres til tykkelser under 60 mm idet sveisingen dermed forenkles betydelig. The invention aims to modify this construction, which is limited by the dimensions and the welding technique, by using steel castings so that both large bending moments and compressive forces can* be transferred and the welding connections can be reduced to thicknesses below 60 mm, as the welding is thus considerably simplified.
På tegningen viser fig. 1 en kjent forbindelse mellom rørstusser og ståldragere ved hjelp av forsterkede rør, fig. 2 viser halvkuleformede stålstøpegodslegemer med påstøpte ender, fig. 3 viser halvkulef ormede stålstøpegodslegemer med konsentrisk påstøpt rør,' fig. 4 viser forbindelse med hjelp av ett eneste halvkuleformet stålstøpegodslegeme og fig. 5 viser forbindelse med hjelp av to halvkuleformede stålstøpegodslegemer. In the drawing, fig. 1 a known connection between pipe ends and steel girders by means of reinforced pipes, fig. 2 shows hemispherical steel casting bodies with cast-on ends, fig. 3 shows hemispherical steel casting bodies with concentrically cast-on pipes, fig. 4 shows connection using a single hemispherical steel casting body and fig. 5 shows a connection using two hemispherical steel casting bodies.
På rørstussens 2 ende buttsveises et tilnærmet halvkulef ormet legeme 6 av stålstøpegods. Dette halvkuleformede legeme har påstøpte ribbeformede deler både i stegenes 7 kryssende plan og i flensenes 8 plan. Flensplanenes høydenivå kan varieres tilsvarende ståldragernes høyde. An approximately hemispherical worm-shaped body 6 made of cast steel is butt-welded to the 2 end of the pipe. This hemispherical body has cast-on rib-shaped parts both in the crossing plane of the steps 7 and in the plane of the flanges 8. The height level of the flange planes can be varied corresponding to the height of the steel girders.
Den på fig. 2 viste ribbeformede del 7 danner sett ovenfra et kryss. Til denne del 7 sveises de kryssende drageres steg og dersom dragerens høyde stemmer overen med de ribbeformede delers 7, sveises også overflensene til disse. The one in fig. 2, the rib-shaped part 7 shown from above forms a cross. The steps of the crossing girders are welded to this part 7 and if the height of the girders matches the rib-shaped parts 7, the upper flanges are also welded to these.
En under hensyn til stigeløputformingen ved støpingen hensiktsmessig, spesiell form inneholder ifølge fig. 3, i midten mellom de steg som krysser hverandre, et påstøpt rør 9. Dette tillater anordning av et sentralt stigeløp og en spesielt enkel avbrenning av denne. Videre har det en spesiell avstivende virkning for de tilstøtende steg. An appropriate special form, taking into account the ladder design during casting, contains, according to fig. 3, in the middle between the steps that cross each other, a cast-on pipe 9. This allows the arrangement of a central ladder run and a particularly easy burning of this. Furthermore, it has a special stiffening effect for the adjacent steps.
Et slikt legeme kan ifølge fig. 4 benyttes alene. Hertil tjener de påstøpte flenser 8 for påsveising eksempelvis på ståldragerens 1 undergurt, mens ståldragerens steg 4 eller overgurt 5 eller kun deler av dens steg 4 sveises til stegene 7. Denne løsning kan være hensiktsmessig i en rammekonstruksjons øverste dekk. Such a body can, according to fig. 4 is used alone. For this purpose, the cast-on flanges 8 are used for welding, for example, on the lower chord of the steel girder 1, while the steel girder's step 4 or upper girder 5 or only parts of its step 4 are welded to the steps 7. This solution can be appropriate in the top deck of a frame structure.
Det halvkuleformede stålstøpegodslegeme 6 kan imidlertid også. benyttes dobbelt som vist på fig. 5, ved at både overgurten og undergurten 5 støpes til legemet 6 og de to legemers 6 påstøpte steg 7 sveises til hverandre. Dette muliggjør forbindelse mellom meget høye ståldragere 1 og deres meget stabile forbindelse til en rørstuss 2 over og under. However, the hemispherical steel casting body 6 can also. is used twice as shown in fig. 5, in that both the upper girth and the lower girth 5 are molded to the body 6 and the two bodies 6 molded steps 7 are welded to each other. This enables a connection between very high steel girders 1 and their very stable connection to a pipe connection 2 above and below.
