摘要

A form for pouring a conical concrete structure has a framework of obliquely inclined beams radiating from the axis of the structure in angularly offset relationship. Circumferentially elongated connecting members connect each beam to the two angularly adjacent beams. They are spaced longitudinally of the beams and sequentially increase in length in a direction away from the axis. Threaded fasteners connect the longitudinally terminal portions of each connecting member to respective connected beams. Sheeting covers the connecting members and is fastened to the members to constitute a substantially conically tapering wall extending about the axis of the form in a closed loop.
