Why facade fall
buildings in the city the past few years more to build, the more build more dense, more and more luxurious facade decoration, from the The initial cement facade, to the coated paint, paste mosaic, glass curtain wall installed, affixed granite, weight on the wall is also growing, and the resulting security risks more and more each year are a wall off of the incident.
Letters recent reports on the facade falling on July 22 last year, all the way across China Resources Supermarket granite wall of a building fell 20, crushing a car and a Mercedes-Benz a gray modern commercial vehicles.
quality inspector for a construction company in Hangzhou Mr Tse said: the risk of falling, and now basically out of this construction method. In order to ensure safety, and now the general approach to double the insurance, first granite plate and base (wall) steel mesh connected with brass banding, and then sand slurry irrigation. / p>
facade off several reasons: either because the proportion of sand and cement not; either because of poor quality sand or cement, such as the use of the sand is too fine, resulting in tack is not enough; also caused some poor construction quality, such as installation, granite is not saturated, the amount of cement not so; thermal expansion and contraction can also cause off the wall; other paste at a gap, a long soaking rain can also cause wall loosening.
In addition, the construction workers also contributed to steal off of the main reasons, the most typical in the old tile is affixed directly on the new tiles. The correct four-step construction procedure should be -
First, the walls knock down all the original surface has been knocked to the concrete floor so far. If there is no cement layer has been exposed to so far hit the bricks.
Second, re-paint the base surface. This has two effects, one waterproof, the second is to increase the tile adhesion.
third tiles.
fourth, pointing. This not only increase the aesthetics and increase firmness.
