Recyclable cylindrical structures and usage methods are provided. A recyclable cylindrical structure includes multiple prefabricated cylindrical units. Each unit is provided with a ring block coaxially fixed on the top of the unit, a ring slot coaxially formed in the bottom of the unit, two first sealing rings arranged on the top of the unit and a second sealing ring arranged on the top of the ring block of the unit. The ring block is provided with multiple first connection elements. Multiple second connection elements are arranged in the ring slot. For two adjacent prefabricated cylindrical units of the recyclable cylindrical structure, the ring block of the lower unit inserts into the ring slot of the upper unit and the first connection elements of the lower unit are corresponding and jammed one-to-one with the second connection elements of the upper unit.

Recyclable cylindrical structure and usage method thereof

The present disclosure provides a cylindrical structure construction platform that both a first telescopic portion and an elastic member drive a guiding wheel to tightly abut against an outer template, adjusting radial positions of a pouring pipe and a tamping device according to an outline of the outer template by a second telescopic portion to reduce construction errors, adjusting an inclination angle of the guiding wheel by an adjusting mechanism, a slewing mechanism driving a rotary table to drive the guiding wheel to climb along a surface of the outer template, the pouring pipe is poured layer by layer from the bottom to the top of a pouring cavity to reduce a height difference during pouring for further reducing generation of air holes, the tamping device vibrates layer by layer from the bottom to the top of the pouring cavity to further eliminate the air holes.

Cylindrical structure construction platform

A construction platform that is freely movable up and down is provided, which includes several curved platforms, several columns and a control panel. The curved platforms are connected with one after the other to form a ring-shaped platform that surrounds a cylindrical building and is movable along the columns. Each curved platform is provided with one or more mounting brackets. Each mounting bracket is provided with one or more movable brackets, one or more pressing mechanisms, one or more locking mechanisms, one or more movable rods, one or more suction cups, a pumping mechanism, and one or more emergency braking mechanisms. Each emergency braking mechanism includes a sprocket, a chain, a counterweight, an angle sensor, and a configuring assembly. Each configuring assembly includes a ring gear, a mounting sleeve, a configuring rod, a pawl, a torsion spring, an electromagnet and a magnetic block.
