Abstract

En fremgangsmåte og apparat for å forbinde seksjoner av et boreriggfundament (5) beskrives. Den viste oppfinnelse er en spesiell konstruksjonskopling hvori seksjoner av et boreriggfundament (5) kan forbindes til hverandre uten bruk av bolter eller koplinger av bolttypen. Konstruksjonskoplingen ifølge den foreliggende oppfinnelse anvender spesielt formede faste holderelementer (61, 62) som er forbundet til og strekker seg gjennom underlagsplater (60) som er festet til seksjoner av et boreriggfundament (5) som sammenpasser med spesielt formede sammenpassende festeører (46, 47) som er montert på sammenpassende festeøreplater (43, 44) som er festet til separate seksjoner av boreriggfundamentet (5). Når seksjonene av boreriggfundamentet (5) som skal forbindes posisjoneres sammen kommer de spesielt formede sammenpassende festeører (46, 47) i inngrep med de spesielt formede holderelementer (61, 62) og danner en konstruksjonsforbindelse med høy styrke mellom seksjonene av boreriggfundamentet (5).A method and apparatus for connecting sections of a drilling rig foundation (5) is described. The present invention is a special structural coupling in which sections of a drill rig foundation (5) can be connected to each other without the use of bolts or bolt type couplings. The structural coupling of the present invention utilizes specially shaped fixed retaining members (61, 62) which are connected to and extend through support plates (60) which are attached to sections of a drill rig foundation (5) which fit into specially shaped mating fasteners (46, 47). which is mounted on matching fastening ear plates (43, 44) which are attached to separate sections of the drill rig foundation (5). When the sections of the drilling rig foundation (5) to be joined are positioned together, the specially shaped matching fastening ears (46, 47) engage the specially shaped holding members (61, 62) and form a high strength structural connection between the sections of the drilling rig foundation (5).
