the specific steps for detaching the first pull rope and the second pull rope are as follows:
after a pull rod is arranged between the adjacent two groups of oblique columns, the first pull rope and the second pull rope are detached with the stress direction close to the adjacent oblique column groups, the stress direction is kept away from the adjacent oblique column groups, the first pull rope and the second pull rope are arranged, all the oblique column groups are treated to pass through the pull rod after being connected into a closed loop structure, and then the first pull rope and the second pull rope are detached with the stress direction away from the adjacent oblique column groups.
10. The construction method of the inverted cone helical building according to claim 8 or 9, wherein the installing of the inner helical ring and the outer helical ring on the inverted cone skeleton comprises the following steps:
spirally mounting the inner spiral annular channel along the inner wall surface of the inverted cone framework from bottom to top until the top surface of the inner spiral annular channel reaches the designed height of the bottom surface of the outer spiral annular channel;
and spirally installing the outer spiral annular channel from bottom to top along the outer wall surface of the inverted cone framework, and simultaneously installing the rest inner spiral annular channels until the inner spiral annular channel and the outer spiral annular channel are closed.
