钢结构在建筑机械上的应用很广泛,是机械的重要组成部分,但对其防腐问题容易被人们所忽视。一般认为钢结构的防腐即是除锈涂漆,实质上,这只是问题的一个方面,更重要的是钢结构设计上和制造上的防腐。本文就此谈一点不成熟的意见。钢结构的防腐,是结构本身的重要要求,是影响钢结构自然寿命的重要因素之一。因此,结构设计时应予以考虑。笔者认为:①应尽量避免出现存水结构。例如,60、80系列塔机底节斜撑铰接点处、底节铰接处、标准节之间子母节口等处出现了存水问题,这不但影响结
Steel structures are widely used in construction machinery and are an important part of the machinery. However, their anticorrosion problems are easily overlooked by people. It is generally believed that corrosion protection of steel structures is rust-removing and painting. In essence, this is only one aspect of the problem. What is more important is corrosion protection in the design and manufacture of steel structures. This article talks about immature opinions. The corrosion of steel structures is an important requirement of the structure itself, and it is one of the important factors influencing the natural life of steel structures. Therefore, structural design should be considered. The author believes that: 1 The structure of water retention should be avoided as much as possible. For example, the problem of water retention occurred at the hinge joints of the bottom section of the 60 and 80 series tower cranes, at the articulated joints at the bottom section, and at the joints between the standard sections. This not only affects the knots.
