摘　　要：拉索式点式玻璃幕墙是近几年国内发展较快的一种新型幕墙体系。其大跨度、超高的索网结构与点式玻璃幕墙共同组成完整的受力平衡体系,施工难度较大。通过对55m高索肋组合点驳接式幕墙的体系深入分析,明确其受力特点,通过仿真模拟验算、明确施工顺序、测量及监测、同步对称张拉等技术,保证了玻璃、索具等材料的下料精度,减少了材料的浪费,提高了点驳件支座的安装精度,降低了幕墙施工成本,加快了施工进度。Point-supporting glass curtain wall with cable net is a new type structure developed rapidly in recent years in China. It has large span,super high cable net structure and point glass rib curtain wall forming a complete force balance system. So it is difficult to construct. Through in-depth analysis of point-supporting glass curtain wall with 55 meters high cable net,characteristics of the system is clear.Through the simulation calculation, clear construction sequences, measurement and monitoring,synchronous symmetrical tensioning technology,the glass,locks and other materials using precision are guaranteed,reducing material waste,improving the installation accuracy. The cost of curtain wall construction is reduced and the construction schedule is accelerated.
