“T”型预制看台板模板支设的优选方法

The Preferred Method of Setting up "T"-type Prefabricated Bleacher Slab

体育场的看台板外形较复杂,在工程实践中,往往采用预制板的形式。无论采用那种形式的预制看台板,模板支设涉及现场预制场地狭小的问题,如果采用传统地模支设,加固较困难。本文系统比较了"T"型预制看台板各类模板的优缺点,得出底模采用钢模,侧模采用木模的优选施工方法;详细阐述了优选方法的各项施工准备、工艺流程、支护工具、施工步骤;提出了模板支设过程中的施工注意事项;分析了优选方法的技术经济优势。

Stadium bleacher has complicated appearances and normally in engineering practice it adopts slab pre-casting.No matter what pre-casting method is adopted,formwork setting-up in a confined space is a problem.The adoption of traditional floor formwork setting may result in reinforcement difficulties.This article compares the pros and cons of all kinds of formwork for pre-casting.The conclusion shows the first choice for floor formwork shall be steel die,the side formwork shall be timber formwork.The article describes in detail the construction preparation,process flow,supporting tool and construction steps,proposes the matters needs to be attention during formwork setting-up,and analyzes advantages of technical and economy.
