Why the glass curtain wall is frequently blew?
Silver billion property company, the reporter went to the Global Centre Block C property said the glass curtain wall from Westin falling 36 floors, it should be responsible by the hotel property.
It is understood that the global center of all the glass curtain wall is by Ningbo glory estate companies responsible for. The person in charge of the company's purchasing department, Liu said that the the company procurement glass are Nanbo glass withstand the test of the quality of this glass, all glass are entrusted to the Shenzhen the Sanxin glass curtain wall company installed this is a public company, the industry is also very famous.
As for why the glass curtain wall will frequently blew, Liu said, all tempered glass the thousandths blew rate, which is the inherent defects of tempered glass. Toughened glass containing nickel sulfide component called, in the thermal expansion and contraction of the case, such small particles will become large to small, and the size of the glass deformation do not coincide. This may cause the glass internal stress change, resulting blew, this is no way to avoid this blew the probability is also relevant national provisions within the allowable range.

Glass curtain wall in dire need of "inhibition"
Da Moke a sword has led the glass curtain wall of the building trend, but now it has become the overhang on each person's head.
Fall wounding after the burst of the glass curtain wall has not news, since blew terms of safety glass, like cancer, can not be overcome, then there is no way to reduce the probability of occurrence of the events of the glass curtain wall blew wounding, after all, we can not always luck and hedge.
Management of the glass curtain wall, promulgated by the Ministry of Construction in 2006 "Existing Building walls Security Maintenance and Administration" in two specific requirements: First, both the safety of the building curtain wall maintenance owner responsible; another local construction authorities should be the responsibility for maintaining the safety of existing buildings curtain wall's compliance with the maintenance of security responsibility to supervise.
In other words, the owners of the house is responsible for the maintenance of the glass curtain wall, maintenance, safety testing. But practical operation, the relationship may not be so simple.
By the contractor responsible for warranty reporter has learned that, within the first two years of use of glass curtain wall, curtain wall company warranty period will be based on the size of the glass curtain wall and the degree of complexity of the process to make proper adjustments, but the warranty period and tempered glass dangerous period "compared to, or have a certain gap.
Out of the warranty period, and you are looking for the owners. But most of the glass curtain wall used in commercial buildings such as hotels, office buildings, especially complex office property rights owner is responsible for safety testing of curtain walls or require the consent of the owners of a certain percentage of the curtain wall security testing, is not easy.
Therefore, the basic maintenance of the glass curtain wall by the property commitments. Commitment to the property maintenance There are several problems: no professional maintenance of technical knowledge, the so-called maintenance is carried out daily cleaning; lack the necessary maintenance funds.
In February this year, the implementation of the glass curtain wall construction management approach ", the way to clear several very important, one of which is to limit the use of glass curtain wall in Shanghai prohibited the T-shaped intersection of the straight sections of the building on the glass curtain wall; prohibit residential, outpatient hospital emergency room floor and ward building, teaching building of primary and secondary schools, nurseries, kindergartens, homes for the aged "above the second floor of Building glass curtain wall; Second, the clear responsibility of the owners and unit in charge of regulatory responsibilities, such as how the glass curtain wall maintenance funds to pay, if the owners is not responsible for the "bear any responsibility for the unit in charge of what kind of punishment is not responsible behavior.
In April of this year, Ningbo the deputies proposed, Ningbo whether similar management approach can also be introduced. But this proposal is the industry means yet to be demonstrated, "For example, the problem of who is going to enforce the law, not one or two hundred people, I am afraid it is not effective."
Yesterday, the Municipal Housing and Urban-Rural Development Committee qualitative Ann at a Chus staff told reporters, according to her understanding, Ningbo yet not introduced the exact schedule of the Measures for the Administration of the glass curtain wall.
