长期以来,人们在修理、维护起重机械时,往往只重视对传动及动力设备的养护,而忽略了对钢结构的检查及修复,给施工带来诸多隐患。在此结合实际经验,谈谈钢结构使用中的损坏原因及维修。钢结构的损坏形式及原因分析 1.1表面锈蚀起重设备工作环境比较恶劣,经常在含酸碱等腐蚀性气体下作业,加上使用中的碰撞及防锈油漆的自然老化、脱落,使表面失去保护,造成局部乃至多层次腐蚀,整体强度下降,不同程度地出现表面锈蚀现象。
For a long time, people often pay attention to the maintenance of transmission and power equipment while they are repairing and maintaining the crane, neglecting the inspection and repair of the steel structure and bringing many hidden dangers to the construction. In this combination of practical experience, talk about the reasons for the use of steel structure damage and maintenance. Steel structure damage and analysis of the reasons 1.1 surface rust Lifting equipment working environment is relatively harsh, often with caustic soda and other corrosive gas operations, coupled with the use of the collision and anti-rust paint natural aging, loss, so that the surface loss Protection, resulting in partial or even multi-level corrosion, the overall intensity decreased, to varying degrees, the phenomenon of surface corrosion.
