Safety Appraisal of Steel Net Frame Roof of Huaibei City Gymnasium

钢网架结构因众多的优点而广泛用于体育馆等公共建筑的屋盖,其缺点为钢构件易腐蚀,耐火性能差。钢网架结构使用一定年限后,因锈蚀等问题易存在安全隐患,严重时需要进行安全性鉴定。文章以淮北市体育馆钢网架屋盖的安全性鉴定为例,总结钢网架结构安全性鉴定的要点,供同类工程参考。

The steel grid structure is widely used in the roofs of public buildings such as stadiums due to its numerous advantages.The disadvantage is that the steel components are easily corroded and have poor fire resistance.After the steel grid structure has been used for a certain period of time,it is easy to have safety hazards due to problems such as corrosion,and it is necessary to carry out safety appraisal when it is serious.This paper takes the safety appraisal of the steel net frame roof of Huaibei City Gymnasium as an example,summarizes the key points of the safety identification of steel net frame structure,and provides reference for similar projects.
