建筑施工中经常发生物体打击事故,这类事故主要是由高处掉落物料和建筑机械在运转中螺母松动飞出等原因所致。预防这类事故的主要措施如下。1.凡4米以上的在施工程,首层要设3-6米宽的安全网,每隔4层再支一道3米宽的固定安全网,施工层处支一道3米宽的安全网。高层施工时,首层网点要支双层6米宽的安全网。若采取立网防护,立网应高出建筑物1米以上。安全网的质量应符合要求。2.各种脚手架的搭设必须符合国家标准。每层要设护身栏和挡脚板。施工层脚手板必须铺严,架子上不准留单跳板、探头板。脚手板与建筑物之间的距离不得大于20厘米。各种脚手架使用前应经过安全技术部门的验收。
Occurred in the construction of an object hit the accident, such accidents are mainly caused by falling materials and construction machinery in the operation of the loose nut flight due to other reasons. The main measures to prevent such accidents are as follows. 1. Where more than 4 meters in the construction process, the first floor should be 3-6 meters wide safety net, every 4 layers and then supported by a 3 m wide fixed safety net, the construction layer at a 3 meters wide support safety net . High-rise construction, the first floor outlets to support double safety net 6 meters wide. If you take the legislation network protection, legislation should be more than 1 m above the building. Safety net quality should meet the requirements. 2. All kinds of scaffold erection must meet the national standard. Each floor to be equipped with fencing and footboard. The construction floor scaffolding must be paved, the shelf is not allowed to stay single springboard, probe plate. The distance between the scaffolding and the building should not exceed 20 cm. Before using a variety of scaffolding safety technical departments through the acceptance.
