Abstract
PURPOSE: To accomplish a manual combination or releasing of the truss posts quickly and accurately in a truss posts combining apparatus for a self-lifting marine working platform.
CONSTITUTION: The truss post 5 is erected on the bottom of sea to retain the working platform 3 on the surface of sea and a drilling is performed on the bottom of sea by an excavating rig. When the apparatus is moved to a remote place, it is separated by a dimension 1 to be placed on another working platform and combined again after moved. At this point, the truss post 5 is cut up into a dimension (a) to be held within the range of lifting capacity of a crane. Overhangs 10' and 11' are mounted horizontally on planks 10 and 11 respectively at the upper end of a lower truss post and at the lower end of an upper truss post. The planks are combined together at the center thereof through a scalelike convex fixture while the overchanges 10' and 11' of the upper and lower truss supports are combined together with an inert fitting 13.
