Fabrication and transport tooling

A transport and assembly alignment tool, for prefabrication, transport, erection and final assembly of a separate plurality of individual near identical arcuate segments each having an inner periphery and an outer periphery manufacture a large annular or toroidal structure or framework, which during final assembly enables the circumferential alignment and facilitates subsequent permanent attachment of the arcuate segments end-to-end to create an annulus or ring that can maintain its circularity and structural integrity without the external support of the tool permitting post-assembly removal of the tool;

• having at least one alignment fixture with the or each alignment fixture comprising a corresponding matched pair of mating first and second alignment members separate and distinct from the arcuate segments comprising a first circularity axial alignment member which can mate and align circumferentially to a second circularity and axial alignment member, a radially extending alignment feature to determine circumferential and tangential alignment of the first and second alignment members when married together and attachment, clamping or locking means to maintain said circumferential alignment and mating contact of the alignment members;
• the first axial alignment member adapted in use to be rigidly but removably secured to a first one of the arcuate segments at or immediately adjacent one circumferential end thereof and similarly the second axial alignment member being rigidly but removably secured to a second one of the arcuate segments at or immediately adjacent one circumferential end thereof;
• wherein a first portion of the first circularity axial alignment member and a second portion of the second circularity axial alignment member each extend radially outward from the outer periphery.
