在《危险性较大的分部分项工程安全管理办法》(建质[2009]87号)中规定,危险性较大的混凝土模板支撑工程为“搭设高度5m及以上;搭设跨度10m及以上;施工总荷载10 kN/m~2及以上;集中线荷载15kN/m及以上;高度大于支撑水平投影宽度且相对独立无联系构件的混凝土模板支撑工程。”超过一定规模的危险性较大的混凝土模板支撑工程为“搭设高度8 m及以上;搭设跨度18m及以上,施工总荷载15kN/m~2及以上;集中线荷载20kN/m及以上。”按照规定,上述工况均须编制专项方案,后者还须组织专家论证。对于搭设高度、跨度、搭设的高宽比及构件连
In the “dangerous part of the project safety management approach” (Jian-quality [2009] No. 87) provides that the more dangerous concrete formwork support project “set height 5m and above; erection span 10m and above ; The total load of construction is 10 kN / m ~ 2 and above; the load of concentrated line is 15 kN / m and above; the concrete formwork supporting project with height greater than the horizontal projection width of support and relatively independent non-contact member. Of the concrete formwork support project is ”erected height 8 m and above; erection span 18m and above, the total construction load of 15kN / m ~ 2 and above; concentration line load 20kN / m and above." According to regulations, Special programs need to be prepared, and the latter must organize expert testimony. For erected height, span, erected aspect ratio and the member even
