某厂房项目大跨度预制双T板滑模安装及吊装施工分析

Analysis of Installation and Hoisting Construction of Long-Span Prefabricated Double-T Plate Slip-Form for a Plant Project

某工程局部区域有夹层结构,双T板无法一次性吊装到位。经对各施工方案的研究、比较和优化,决定采用滑模施工工艺。论文主要研究了大跨度预制双T板安装过程中使用滑模桁架的施工工艺和流程,并对吊装施工的验算复核进行了分析。

Because of the sandwich structure in some areas of a project,the double T plate can not be hoisted in place at one time.After the study,comparison and optimization of each construction scheme,it is decided to adopt the slip-form construction technology.This paper mainly studies the construction technology and flow of slip-form truss used in the installation process of long-span prefabricated double T plate,and analyzes the checking calculation of hoisting construction.
