Description
Foreliggende oppfinnelse angår en fremgangsmåte ved bygging The present invention relates to a method for construction
av skip ved sammenstilling av sveisede skrogenheter. of ships by assembly of welded hull units.
Hittil er sådanne pre-fabrikerte skrogenheter fremstilt i normal stilling og overført til byggedokken i denne stilling, dvs. Until now, such pre-fabricated hull units have been produced in a normal position and transferred to the construction dock in this position, i.e.
den stilling som enheten vil ha i det ferdige skipsskrog. Forflytting av enhetene i denne stilling blir imidlertid i økende grad vanskelig og farlig ettersom enhetenes størrelse øker. the position that the unit will have in the finished ship's hull. However, moving the units in this position becomes increasingly difficult and dangerous as the size of the units increases.
Det er derfor et formål for foreliggende oppfinnelse å angi en It is therefore an object of the present invention to indicate a
ny fremgangsmåte ved bygging av skip, og som muliggjør forflytting av skrogenhetene og sammenstilling av disse til vedkommende skrog å bli utført sikkert og lett. new procedure for building ships, which enables the movement of the hull units and assembly of these to the relevant hull to be carried out safely and easily.
Det særegne ved fremgangsmåten i henhold til oppfinnelsen består The peculiarity of the method according to the invention consists
i kombinasjonen av følgende trinn: in the combination of the following steps:
at de sveisede skrogenheter overføres til kanten av en byggedokk hvis sidekant ligger høyere enn dokkbunnen idet skrogenhetene holdes med forbindelsesaksen mellom dekkplater og bunnplater liggende horisontalt, that the welded hull units are transferred to the edge of a construction dock whose side edge is higher than the dock bottom, with the hull units being held with the axis of connection between deck plates and bottom plates lying horizontally,
at bunnplatepartiet av enheten føres ut over dokk-kanten og inn i dokkområdet, that the bottom plate part of the unit is led out over the dock edge and into the dock area,
og at enheten reises opp til vertikal stilling for forbindelsesaksen mellom dekkplater og bunnplater ved å vippes om en horisontal akse ved sidekanten av dokken, idet skrogenhetens bunnplate dermed senkes ned til dokkbunnen. and that the unit is raised to a vertical position for the connecting axis between cover plates and bottom plates by tilting about a horizontal axis at the side edge of the dock, the bottom plate of the hull unit being thus lowered to the bottom of the dock.
Oppfinnelsen vil bli bedre forstått ut fra følgende beskrivelse under henvisning til vedføyde tegning. Fig. 1 er en perspektivskisse som viser fremstilling av en pre-fabrikert skrogenhet. Fig. 2 er et lengdesnitt som viser dreiningen av en sådan pre-fabrikert skrogenhet'om dokk-kanten. The invention will be better understood from the following description with reference to the attached drawing. Fig. 1 is a perspective sketch showing the manufacture of a pre-fabricated hull unit. Fig. 2 is a longitudinal section showing the rotation of such a prefabricated hull unit around the edge of the dock.
Det skal nå henvises til tegningen og særskilt til fig. 1. Etter kjent teknikk fremstilles en pre-fabrikert skrogenhet på en sådan måte at en skottvegg 2 i lengderetningen, en sideplate 3 og en tverrstilt skottvegg 4 alle oppstilles i normal stilling og festes til en bunnplate 1 som er plassert på et underlag, hvoretter dekkplaten 5 festes til den således fremstilte konstruksjon. Reference must now be made to the drawing and in particular to fig. 1. According to known techniques, a pre-fabricated hull unit is produced in such a way that a longitudinal bulkhead 2, a side plate 3 and a transverse bulkhead 4 are all set up in a normal position and attached to a bottom plate 1 which is placed on a base, after which the deck plate 5 is attached to the structure produced in this way.
- Denne fremgangsmåte krever meget sveisearbeide høyt oppe eller - This procedure requires a lot of welding work high up or
i retning oppover fra sveiseren dvs. slik at en må se opp mot sveisestedet. Sådant arbeide er vanskelig og farlig, og dette gjelder iøkende grad ettersom enhetenes størrelseøker. I overensstemmelse med den her omhandlede fremgangsmåte, plasseres imidlertid den tversgående skottvegg 4 på underlaget, slik som vist i fig. 1, hvoretter den langsgående skottvegg 2, sideplaten 3, bunnplaten 1 og dekkplaten 5 festes til tverrveggen, således at konstruksjonen som helhet vil være lavere. Hvis blokken i tillegg dreies om aksen X-X gjennom dekkplaten og bunnplaten, vil alt sveisearbeide kunne utføres i retning nedover for sveiseren, dvs. slik at sveiseren kan se ned mot sveisestedet. in an upward direction from the welder, i.e. so that you have to look up towards the welding site. Such work is difficult and dangerous, and this applies to an increasing degree as the size of the units increases. In accordance with the method described here, however, the transverse bulkhead wall 4 is placed on the substrate, as shown in fig. 1, after which the longitudinal bulkhead 2, side plate 3, bottom plate 1 and cover plate 5 are attached to the transverse wall, so that the construction as a whole will be lower. If the block is additionally rotated about the axis X-X through the cover plate and the bottom plate, all welding work will be able to be carried out in a downward direction for the welder, i.e. so that the welder can look down towards the welding site.
Da imidlertid ikke den pre-fabrikerte skrogenhet kan bygges inn i skipsskroget i denne stilling, må enheten dreies til normal innbyggingsstilling. Den pre-fabrikerte enheten forskyves da i henhold til foreliggende oppfinnelse til kanten av bygningsstokken, mens hele tiden linjen X-X holdes horisontal, slik som vist i fig. 2. ■ Når den forflyttes på denne måte, er den pre-fabrikeirte enhet stabil under transporten, og dette resulterer da i øket sikkerhet og lettere arbeidsforhold under transporten. Ved kanten av dokken 6 er det anordnet et svingbord 7, som er dreibart om en horisontal akse 8. En hydraulisk heve-innretning 9 er anordnet under svinge-bordet 7 og et passende antall hydrauliske sylindre 10 er montert i bunnen av dokken. However, since the prefabricated hull unit cannot be built into the ship's hull in this position, the unit must be turned to the normal installation position. The pre-fabricated unit is then moved according to the present invention to the edge of the building block, while the line X-X is kept horizontal all the time, as shown in fig. 2. ■ When moved in this way, the prefabricated unit is stable during transport, and this then results in increased safety and easier working conditions during transport. At the edge of the dock 6, a swivel table 7 is arranged, which can be rotated about a horizontal axis 8. A hydraulic lifting device 9 is arranged below the swivel table 7 and a suitable number of hydraulic cylinders 10 are mounted at the bottom of the dock.
Den pre-fabrikerte enhet 12 anbringes på sving-bordet 7, hvoretter bordet dreies.om aksen 8 mot urvisernes retning ved hjelp av heveinnretningen 9. Stempelstengene 11 i dé hydrauliske sylindre 10 senkes suksessivt mens de hele tiden holdes i kontakt med svingbordet 7, som dreies slik som antydet med stiplete linjer i fig'..2... På denne måte kan den pre-f abrikerte enhet oppstilles'' på bunnen av dokken i normal stilling. Den oppstilte enhet transporteres deretter til resten av skroget og sammenføyes med dette. The prefabricated unit 12 is placed on the turntable 7, after which the table is rotated around the axis 8 in a clockwise direction by means of the lifting device 9. The piston rods 11 in the hydraulic cylinders 10 are successively lowered while they are constantly kept in contact with the turntable 7, which rotated as indicated by dashed lines in fig'..2... In this way, the prefabricated unit can be set up'' on the bottom of the dock in the normal position. The erected unit is then transported to the rest of the hull and joined with it.
Det ovenfor beskrevne svingbord er ikke alltid nødvendig. Det ville også være mulig å anordne ruller ved sidekanten av dokken for dreining og føring av vedkommende skrogenhet. Kraner kan også anvendes for tipping av den pre-fabrikerte enhet, istedetfor de ovenfor angitte hydrauliske mekanismer. The turntable described above is not always necessary. It would also be possible to arrange rollers at the side edge of the dock for turning and guiding the relevant hull unit. Cranes can also be used for tipping the prefabricated unit, instead of the above-mentioned hydraulic mechanisms.
I henhold til foreliggende oppfinnelse kan således den pré-fabrikerte skrogenhet lett svinges uten anvendelse av stor kraft, fordi den tippes om sidekanten av dokken. Videre kan den pre-fabrikerte blokk lett og sikkert forskyves i en stilling hvor forbindelsesaksen gjennom dekkplaten og bunnplaten holdes horisontal. According to the present invention, the pre-fabricated hull unit can thus be easily swung without the use of great force, because it is tipped over the side edge of the dock. Furthermore, the pre-fabricated block can be easily and safely moved into a position where the connection axis through the cover plate and the bottom plate is kept horizontal.
