超高层核心筒液压爬模施工技术

CONSTRUCTION TECHNIQUE OF HYDRAULIC CLIMBING FORMWORK FOR SUPER-HIGH CORE TUBE

北京绿地中心超高层工程在核心筒结构施工中采用液压爬模体系,保证了核心筒墙体结构安全。同时,施工中针对水平构件钢筋连接做法、墙体变截面、桁架层托座、塔式起重机爬升等施工难点提前制订了一系列措施,特别针对高空消防安全采取了预控措施,取得了良好的效果。

Hydraulic climbing formwork was used for construction of core tube structure in the super-high Beijing Greenland Center project, to guarantee the structural safety of core tube wall. Meanwhile, a series of measures were prepared in advance against construction difficulties, such as connection of steel bars in horizontal component, variable cross-section of wall, base of truss layer and climbing of tower crane, etc., and advance control of fire and safety at high altitude were also adopted. These measures realized favorable construction effects.
