随着社会的进步和城市现代化建设的发展,大量大型工业、公共建筑的兴建,超高、大跨度构件的工程越来越多。高大模板支撑体系也越来越多的应用在建筑施工中,施工单位作为工程建设的责任主体之一,必须在施工过程中进行安全施工,确保人民生命财产的安全。国家住房和城乡建设部将搭设高度8m及以上;搭设跨度18m及以上,施工总荷载15kN/m2及以上;集中线荷载20kN/m及以上(即俗称“两超一大”)的混凝土模板支撑工程规定为超过一定规模的危险性较大的模板工程及支撑体系分部分项工程范围,并就防范和遏制其所引起的建筑施工生产安全事故的发生作出严格规定。本文分析高大模板在施工中应注意的问题,以做到符合规范要求、按施工方案正确施工、保证施工安全、最终保障结构安全。
With the progress of society and the development of urban modernization, a large number of large-scale industrial and public buildings have been built and more and more projects of ultra-high and long-span components have been built up. Tall template support system is also more and more used in construction, construction unit as one of the main responsibility for the construction, construction must be carried out in the safe construction to ensure the safety of people’s lives and property. The Ministry of Housing and Urban-Rural Development will set up a height of 8m and above; set up a span of 18m and above, with a total construction load of 15kN / m2 and above; concrete with a load of 20kN / m and above (commonly known as “two super and one big” Template support engineering provisions for more than a certain size of the greater risk of the template project and support system sub-project scope, and to prevent and curb the construction safety accidents caused by it to make strict rules. This paper analyzes the tall formwork in the construction should pay attention to the problem, in order to meet the requirements of the specification, according to the construction program of the correct construction, to ensure construction safety, and ultimately ensure structural safety.
