摘要
近年来我国高大模板坍塌事故时有发生,国家及地方行政部门对此虽然进行了重点整治,但仍无法从根源上杜绝。介绍了英美相关规范对模板支架在设计荷载、设计方法和施工管理等方面的规定,比较了中外规范的不同之处,提出模板支架施工中,我国在荷载、设计以及搭设质量检查验收等方面的注意事项。指出应重视剪刀撑的作用,充分考虑施工过程中模板支架可能承受的动力荷载,以提高模板支架的安全水准。
Recently,although national and local administrations have taken a lot of measures,collapses of formwork often happen in China. The requirements on design loads,design method and construction management of formwork in British and American codes are introduced. On the basis of comparison between Chinese and foreign codes,some useful revelations are obtained and suggestions on loads,design and detection and acceptance for the construction of formwork in China are given. Furthermore,it is pointed out that bridging should be paid more attention during construction,as well as the dynamic loads of formwork support,to improve the safety level.
