METHOD OF ERECTING HIGH-RISE REINFORCED CONCRETE STRUCTURES, FOR EXAMPLE, INDUSTRIAL CHIMNEY-STACKS AND TOWERS

摘要

FIELD: construction.SUBSTANCE: invention relates to construction of high-rise reinforced concrete chimney-stacks and towers. Proposed method consists in using multi-cage mine hoist to rise concrete mix and reinforcements into area of their packing. Besides it includes rising riggers by cargo-and-passenger lifter arranged in one of the cages of said mine hoist to working area. Also it includes displacing working platform by lifter embracing said mine hoist from outside to work at different decks. This method uses external lifting travelling shuttering mounted on supports recurred and rearranged in lifting at embedded anchors. External and internal boards feature large-block unified design to be lifted by pulley blocks mounted on circular monorails arranged at mounting platform of lifter. Said boards are displaced from concrete surface to distance friendly for cleaning and lubrication. Compensation boards are arranged between internal and external boards. Note here that said compensation boards are suspended to beams of working platform to lift them therewith and to move them away from concrete by pull-off device arranged at working platform beams. Said compensation boards displace over rollers on working platform beam. Boards are centred and braced together. After laying concrete in moulds and concrete hardening, vertical reinforcements are mounted from special platform while horizontal reinforcements are fitted in place from working platform.EFFECT: lower costs, faster construction, higher quality and safety.8 dwg
