Concrete residential life of at least 1000?

All types of housing network in the past, there is always the certainty of residential life of 30 years, 50 years to prove the absurd conclusions such as homeowners, and such remarks to now no one can reasonably argue. Indeed, the relevant norms have said very clearly: the ordinary civil construction is in accordance with 50-year design life.

House life expectancy is only 30 years, you buy a mortgage for 30 years is a bunch of garbage? House life expectancy is only 50 years, then, even now have, we can not leave the next generation too?

And it is interesting to note that the use of 50-year life of the house turned out to be 70 years, which adds to the mystery of residential life, so many people did not believe he lived in the house, plus the constant crack house to see outdoor pavement subsidence, more panic buyers together to denounce these "shabby."

However, the fact is that so?

Of course not, today, I can certainly tell you that the average life expectancy of concrete shear wall frame house is more than 300 years, the average life expectancy of multi-storey residential concrete frame is more than 1000, the average life expectancy concrete frame villa is more than 10,000 years. Shocked you!

First, the impact of the structural life of what?

Second, in addition to the structure of life, the life of the building itself, there are those problems?

Pick a major say. Own house decoration will change, not to mention.

Pipeline: 15 years to 50 years

Waterproof: 10 years to 15 years

Elevator: 15 years to 20 years

Wall decoration: 15 years to 20 years

These kind of things need to remind it. Basically the house after 98 years in charge of road are not buried in concrete inside, so easy maintenance, replacement is easy. Waterproof mainly roofing and facades, repair when you can handle, construction quality is not bad as long as a few years on the bad, the body maintenance payments basically enough. Elevator can be a major problem, but fortunately a lot cheaper now lift.

These maintenance problems currently houses the main problem is not the quality of the project, precisely, is really to be replaced when the owners are not necessarily the views of unity, not pushed everyone leak, all the electrical short circuit, appeared elevator accident to know to deal with. In fact, if the district consensus, each scrape together a few thousand pieces, bulk gold is not enough to solve the problem.

Calmly say, blow up the reconstruction of the house, but also 2000 per square meter.

Having said that, I do not know clearly no. Simply put your conclusion. House wooden structure can be used for hundreds of years, thousands of masonry everywhere, and reinforced concrete machinery commodity house almost unlimited life.
