[0002] As a common structural form at home and abroad, the spiral concrete staircase is also widely used in water. For the underwater vase-shaped pedestal, a spiral concrete staircase is needed as a connecting walkway from the pedestal body to the pedestal top. Usually, cast-in-place construction is adopted on water, but its construction speed is slow, temporary measures consume a lot of materials, and the technical and economic cost performance is low; if prefabricated hoisting construction is adopted, the requirements for the hanger are relatively high, and it must be able to meet the requirements that after the hoisting of the stairs is completed, the hanger will not overturn, and it must not be interfered with by the platform and the body of the vase-shaped pedestal. The on-site requirements are very harsh. The stair installation devices in the prior art are mostly fixed and non-adjustable hangers.

When the hoisting structure is pulled out, it is easy for the hanger to overturn or collide with the stairs and the pedestal. That is, the hoisting in the prior art is difficult to meet the hoisting of the spiral concrete staircase. Utility Model Content

[0049] Install concrete stairs: After the trial hoisting and adjustment are completed, place the prefabricated spiral staircase on the base, fill the water tank with water to the scale line, connect the top of the support frame to the lifting equipment, use the lifting equipment (crane ship) to lift the support frame, water tank, and prefabricated spiral staircase together smoothly, hoist them to the work station, and place the prefabricated spiral staircase flat on the elliptical vase-shaped platform ladder beam, leaving a 5 cm gap between the staircase and the platform body for subsequent blocking;

[0050] Release the counterweight and remove the bracket: When the prefabricated rotating concrete staircase contacts the pedestal, the self-weight of the prefabricated rotating staircase is transferred from one side of the support frame to the pedestal. By releasing the water in the water tank, the forces on both sides of the support frame are adjusted to ensure the stability of the support frame. The support frame is detached from the rotating concrete staircase that has been placed in place to keep the support frame stable.
