预制构件高空坠落是非常危险的。为了防止事故发生,施工现场操作人员必须在构件挂钩起吊时检查和判断吊环的安全情况。说到这,自然会提出检查图纸设计,吊环的钢筋截面和锚固长度是不是符合规范要求,这无疑是重要的一环。但是,设计无误不等于施工无误,构件生产无误不等于安装起吊无误。每一环节均失误都有可能导致事故。那么,构件吊装过程中的检查和判
It is very dangerous for a prefabricated unit to fall from a height. In order to prevent accidents, the operator at the construction site must inspect and judge the safety condition of the rings when the components are hooked and hoisted. Speaking of this, it will naturally be proposed to check the design of the drawings. Whether the reinforced section and the anchorage length of the rings are in compliance with the requirements of the specification is undoubtedly an important link. However, designing without error does not mean that the construction is correct, and the correct production of the components does not mean that the installation has been hoisted correctly. Every mistake in every link can lead to an accident. Then, the inspection and judgment during the lifting of the components
