Maintenance and repair of the glass curtain wall

Date：2013-12-07 Author：zhaoyang Hits：1292

Curtain wall design and life metal wall is a relatively new peripheral structure , information about its durability is very small , and the construction of a metal plate durability test method can determine the methods and results have not yet fully determined. Therefore , the metal walls of the durability and performance of all other similarly graded , there is impossible. However, in the design and production and prices to be determined , it is impossible without considering the durability of this difficulty. Therefore, I hope to solve the problem of durability representation . As long as proper maintenance and repair, expected durability of more than 30 or 50 years of curtain wall durability , can be considered part of the upper or upper , inappropriate to ask the price of ordinary metal wall with a longer useful life is unreasonable.

The useful life of the building or part of its concept of useful life , usually divided into physical useful life and economic life of two , which in turn are divided into purely economic useful lives and social service lives . Physical limits of useful life is the number of years from a technical point of view , that it is impossible to use.

Economic durable life refers to the technique can still be used . But from the perspective of the maintenance costs of starting a new replace the old limit the number of years is more beneficial. Social service lives from an economic point of view though still can, but and social development compared to the design performance are obsolete . Limit the number of years that end should be updated .

Useful lives to the economic and social considerations are reasonable. However, mechanical equipment there should be studied in depth , in order to make the problem of simplicity, consider only the physical useful life , however , as a limit of two basic challenges: how to estimate the frequency and extent of repair , as well as parts of the problem repaired . How to determine whether it is durable state , coupled with insufficient quantitative data , is still unable to work out a reasonable standard . Physical useful life , obviously depending on environmental conditions around the building and the maintenance of the degree of management. Even if these conditions are the same , there are many factors not clear , therefore , the useful life of the variables considered to have a considerable probability that the dispersion is more secure, even if the expected value is the same , the reliability is not the same .

Node maintenance methods . Node is the main accessory curtain walls and floor connections. Anticorrosive surface treatment in order to be generally taken for A 3 zinc plated steel , installed and then painted red iron surface rust primer . Floor without seal repair node can always check and found that corrosion can then be painted locally polished , if the bolt is loose , re- tighten. Floor seal repair regularly check time is two years in arrears. Local examination , checking all the problems found and embalmed.
