我们知道，移动脚手架的使用都是有年限的，理论上来说是十年，但往往由于维护不到位，发生变形，磨损等情况，使用年限大大缩短。还有在保管中的不当，造成部分配件丢失的情况也时有发生，这些都使得生产成本大大提高。要想延长移动脚手架的使用年限，要注意以下几点：

We know that mobile scaffolding is used for a period of ten years in theory, but often due to inadequate maintenance, deformation, wear and tear, the service life is greatly shortened. There are also inappropriate storage, resulting in the loss of parts from time to time, which makes the production cost greatly increased. To extend the service life of mobile scaffolding, we should pay attention to the following points: 首先，以碗扣式脚手架为例，在施工中要严格按照规划施工，避免不必要的耗损。碗扣式脚手架有些配件是极易损坏的，所以要有一定经验的专业人员进行施工，这样可以有效减少损失，同时保证作业安全。

First of all, take the bowl-buckle scaffold as an example, in the construction, we should strictly follow the planning construction to avoid unnecessary wastage. Some parts of bowl-buckle scaffolding are extremely vulnerable to damage, so we need experienced professionals to carry out construction, which can effectively reduce losses, while ensuring the safety of operation.

第二，妥善保管。在放置脚手架时要做好防水、防潮措施，避免发生锈蚀。同时排放有序，这样方便规范化管理，也不容易造成配件的混乱或者丢失，所以最好是有专人负责架子的回收入库，对于使用情况随时记录。

Second, keep it safe. When placing scaffolds, waterproofing and moisture-proof measures should be done to avoid corrosion. At the same time, the discharge is orderly, which is convenient for standardized management, and it is not easy to cause chaos or loss of accessories, so it is better to have a special person responsible for the shelf recycling and storage, and record the use situation at any time.

第三，定期维护。要定期对架子涂抹防锈漆，一般两年一次。湿度比较大的地区，要求一年一次，以保证架子不会发生锈蚀。

Third, regular maintenance. It is necessary to apply antirust paint regularly to the shelves, usually two years. In areas with relatively high humidity, it is required once a year to ensure that the shelves will not rust.

对于从事移动脚手架租赁的企业来说，延长架子使用年限，可以提高使用率，创造更多的收益。当然到了国家规定的使用年限，我们也要按照规定做报废处理，这也直接关系到施工安全以及企业信誉。

For enterprises engaged in scaffolding leasing, extending the shelf life can improve the utilization rate and create more revenue. Of course, when it comes to the service life stipulated by the state, we should also dispose of the scrap according to the regulations, which is also directly related to the construction safety and the credibility of enterprises.

　　脚手架和矩形管冷弯成型时不同的特点冷弯脚手架、冷弯矩形管是通过外辊与管坯外壁的单向接触形成弯矩使带料弯折,冷弯会使弯折线产生压缩,压缩效应使弯折线纵向伸长,弯折处金属出现堆积变厚,这就是冷弯的压缩/增厚效应。Cold-formed square pipe and cold…
