摘要
为解决大型工业厂房中高大截面现浇钢筋混凝土柱的模板支设难度大且施工质量不易保证等问题,提出一种现浇钢筋混凝土柱半装配化工艺,其利用柱模板钢托架使柱模板与柱钢筋笼组装为一起,整体吊装直插入预留柱基础后再进行混凝土现场浇筑.本文对半装配化现浇混凝土柱的施工过程和工艺设计进行了研究,并进行了必要的力学分析.数值分析及工程实际应用结果表明:此工艺满足安全性要求且安装简单快捷,缩短了施工工期,具有良好的经济效益和社会效益.
In order to solve the problems of formwork support and construction quality of cast-in-place reinforced concrete column with high cross-section in large-scale industrial plant,a semi-assembly technology of cast-in-place reinforced concrete column is proposed,in which the column template is assembled with the column reinforcement cage by using the column template steel bracket,and the overall hoisting is directly inserted into the reserved column foundation,and then the concrete is poured on site.In this paper,the construction process and process design of semi-assembled cast-in-place concrete column are studied,and the necessary mechanical analysis is carried out.Results of numerical analysis and engineering application show that the technology meets the safety requirements,and the installation is simple and fast,which shortens the construction period and has good economic and social benefits.
