近年来,在房屋建筑和公共工程的墙体施工中,钢制大模板的使用显著增加,发生的事故也不断增加,其次数现已和吊装工程或土方工程事故的次数相近。据不完全统计,因模板倾倒而造成的事故占92%;另外,人从模板上坠落的事故占8%。这些数字表明因模板倾倒而造成的事故远比其它事故为多。1.模板倾倒的直接原因因风对模板的作用力倾倒的占76%;因模板被一运动物体碰撞倾倒的占4%;由于其它外力使模板重心移动而倾倒的占20%。因风力作用造成模板倾倒所占的比重很
In recent years, in the construction of walls for house construction and public works, the use of large steel formwork has increased significantly, and the number of accidents has increased. The number of accidents is similar to the number of accidents in lifting or earthworks projects. According to incomplete statistics, accidents caused by the dumping of templates accounted for 92%; in addition, 8% of accidents caused by people falling from the formwork. These figures show that the accidents caused by the dumping of the template are far more than other accidents. 1. The direct cause of the template dumping is 76% due to the force of the wind acting on the template; 4% due to collision of the template with a moving object; and 20% due to the displacement of the center of gravity of the template due to other external forces. The proportion of dumping due to wind force is very high
