标准化安全措施在超高层钢结构建筑中的应用

Application of Standardized Safety Measures in Super High-Rise Steel Structure Buildings

北京某超高层项目采用框筒结构,核心筒为钢板墙暗柱,外框为钢柱钢梁楼层板框架结构。施工过程中核心筒钢板墙施工在上部,外框钢柱钢梁施工在中部,外框楼层板施工在下部,其余土建机电施工紧随钢结构。因此各工序交叉作业频繁,容易产生物体打击、高空坠落、机械伤害、触电、火灾等安全隐患。本文通过某项目为实例,论述该项目为消除隐患,采用高空焊接平台、装配式水平通道、钢板墙操作平台、外挑网、焊机房、屯料平台、钢梁焊接挂笼、爬梯等标准化安全措施,以供相关人员参考。

A super high-rise building project in Beijing adopts a frame-tube structure,with a steel plate wall embedded column as the core tube and a steel column and steel beam floor plate frame structure as the outer frame.In the construction process,the steel plate wall of the core tube is constructed in the upper part,the outer frame steel column and steel beam are constructed in the middle part,the outer frame floor plate is constructed in the lower part,and the rest civil mechanical and electrical construction follows the steel structure.Therefore,the cross-operation of each process is frequent,which is easy to produce potential safety hazards such as object strikes,high-altitude falls,mechanical injuries,electric shocks,and fires.This paper takes a project as an example and discusses the standardized safety measures such as high-altitude welding platform,prefabricated horizontal channel,steel plate wall operation platform,external lifting net,welding machine room,storage platform,steel beam welding hanging cage,and ladder to eliminate hidden dangers,for the reference of relevant personnel.
