Abstract

The invention discloses a self-climbing formwork and a core tube binding construction method, and is applied to the field of core tube construction. The self-climbing formwork comprises a lifting frame. The lifting frame is installed on the side face of the core tube and can climb upwards. The lifting frame comprises a top platform, a bar binding platform, a transition platform and a formwork operation platform which are sequentially arranged at intervals from top to bottom. The top platform is used for storing steel bars and binding the steel bars, the bar binding platform is used for binding the steel bars, and the transition platform and the formwork operation platform are used for formwork construction. When the self-climbing formwork is constructed, the top platform and the bar binding platform provide working faces for reinforcement workers to bind super-layer steel bars, the phenomenon that the reinforcement workers have no working faces in the mold closing stage and the concrete pouring stage, and consequently work idling is caused can be avoided, and the comprehensive efficiency of core tube construction is improved.

Description

technical field [0001] The present application relates to the field of building construction, in particular to a self-climbing formwork frame and a core tube binding construction method. Background technique [0002] A series of super high-rise buildings constructed in my country generally adopt the structural form of a steel structure outer frame and a reinforced concrete core tube, and often adopt a construction method in which the core tube is poured ahead of the outer frame. The main process of core tube construction includes steel bar binding, formwork erection, concrete pouring and curing, formwork removal and other construction procedures, involving the cross work of steel bar, formwork and concrete work shifts. For the construction of the core tube with a large cross-sectional area, at least two assembly line construction sections can be divided at the same height of the core tube to carry out the construction separately, so as to ensure that each work class can carr...
