BESKRIVELSEDESCRIPTION
BenævnelseDenominations
Fundering af rørtårn via RockAdapter flange opdelt i segmenter. AnvendelsesområdeFoundation of pipe tower via RockAdapter flange divided into segments. Field of application
Anvendes til at fundere rørtårne til f.eks. vindmøller på hård jordbund med forankrings kapacitet.Used to fund pipe towers for e.g. wind turbines on hard ground with anchoring capacity.
Kendt teknikPrior art
RockAdapter princippet har tidligere været anvendt til fundering af rørtårne på klippe, idet metoden er fordelagtig pris- og tidsmæssigt samt med mindst mulig anvendelse af materialer for minimeret miljøpåvirkning.The RockAdapter principle has previously been used for founding pipe towers on rock, the method being advantageous in terms of price and time, and with the least possible use of materials for minimized environmental impact.
En ståladapter anbringes på et afrettet betonlag på klippen og forankres direkte ned i klippen via et antal efterspændte ankre.A steel adapter is placed on a cut concrete layer on the rock and anchored directly into the rock via a number of tensioned anchors.
Klippen under adapteren anvendes som modvægt til det væltende moment fra rørtårnet, idet ankrene sammensyr en tilstrækkelig stor klippe masse.The rock under the adapter is used as a counterweight to the overturned torque from the pipe tower, as the anchors coalesce a sufficiently large rock mass.
Den kendte adapter type består af en bundflange med forankringshuller, et opdelt svøb, samt en topflange tilpasset bundflangen i rørtårnet. Alt i en sammensat enhed.The known adapter type consists of a bottom flange with anchoring holes, a split sleeve, and a top flange adapted to the bottom flange of the tube tower. All in one composite unit.
Det tekniske problemThe technical problem
Belastninger fra rørtårn i form af lodret last, vandret last samt bøjende moment skal overføres til klippen både for ekstrem last og udmattelse (f.eks. produktionslast for vindmøller).Loads from pipe towers in the form of vertical load, horizontal load and bending torque must be transferred to the rock both for extreme load and fatigue (eg production load for wind turbines).
Adapteren skal kunne overføre belastningerne i alle tilfælde med passende sikkerhed.The adapter must be able to transfer the loads in all cases with appropriate safety.
Endvidere må jordbunden ikke "mærke” udmattelses belastningerne, hvorfor disse skal være optaget inden via efterspændte ankre.Furthermore, the soil must not "feel" the fatigue loads, which is why these must be absorbed within via tensioned anchors.
DK 2003 00203 U3DK 2003 00203 U3
Den nye teknikThe new technique
RockAdapteren udføres udelukkende som en bundflange i tilstrækkelig tykkelse med huller for forankring, samt huller der modsvarer bundflangen på rørtårnet.The Rock Adapter is designed exclusively as a bottom flange of sufficient thickness with holes for anchoring, as well as holes corresponding to the bottom flange of the tube tower.
Endvidere opdeles RockAdapteren i et antal segmenter for lettere fremstilling, transport og montage.Furthermore, the Rock Adapter is divided into a number of segments for easier manufacture, transport and assembly.
Teknisk virkningTechnical effect
Rockadapteren samles og fastholdes på stedet for etablering af efterspændt forankring i jordbunden.The rock adapter is assembled and retained at the site for the establishment of tensioned anchorage in the soil.
Rørtårnet monteres direkte på toppen af Rockadapteren via f.eks. gevindhuller.The pipe tower is mounted directly on top of the Rock adapter via e.g. threaded holes.
Herefter kan de ønskede belastninger overføres direkte igennem Rockadapteren (flangen) til den etablerede forankring. Svejsning er ikke nødvendigt ved fremstilling af adapteren, hvilket gør kraftoverførslen i adapteren uafhængig af svejsesømmes ringe bæreevne til udmattelse.The desired loads can then be transferred directly through the Rock adapter (flange) to the established anchorage. Welding is not necessary in the manufacture of the adapter, which makes the transfer of power in the adapter independent of the low bearing capacity of the weld seams for fatigue.
Opdelingen i segmenter får kun mindre betydning for kraftoverførslen, idet flangen nu ikke kan forudsættes kontinuerlig hvor der er etableret opdeling.The division into segments only becomes less important for the transmission of power, since the flange can now not be assumed continuously where a division has been established.
Idet Rockadapteren er presset ned mod jordbunden gennem efterspænding af forankringen vil jordbunden således ikke få udmattelses påvirkning. Denne er allerede optaget ved efterspænding og kun højere ekstrem belastninger giver yderligere belastning.As the Rock adapter is pressed down to the soil through tensioning of the anchorage, the soil will not have the effect of fatigue. This is already occupied by post-tensioning and only higher extreme loads provide additional load.

Det nye ved frembringelsen er reduceringen af RockAdapteren til kun af bestå af en flange, samt at flangen opdeles i et antal segmenter.What is new about the generation is the reduction of the Rock Adapter to consist of only one flange, and that the flange is divided into a number of segments.
