[China Glass Network] In order to protect the safety of people's lives and property, the current work of eliminating the risk of Xiamen glass curtain wall has been realized. For the identification standards and technical means of the glass curtain wall, the Municipal Construction Bureau, as the regulatory department, also took the lead in formulating relevant regulations and provided “technical guidance†for the owners and appraisers.
Keywords: realization of institutionalized management for the glass curtain wall "on the account", issued a self-test reminder
In order to avoid accidents caused by the aging of the glass curtain wall, the Municipal Construction Bureau first started from "finding the bottom of the family" and institutionalized the management of the glass curtain wall of the city on the basis of monitoring the dynamic changes.
Since 2011, the Municipal Construction Bureau has started a general survey of the city's high-rise buildings, and has built a file for the glass curtain wall of the city's buildings, such as “upper residence†and “archivesâ€, closely monitoring the use and age of the glass curtain wall, and establishing a long-term management mechanism. According to statistics, there are currently 1048 glass curtain wall buildings in the city. According to the age, the Municipal Construction Bureau has classified and archived them, and the statistical data will be updated every year. The relevant person in charge told the reporter that the cities that independently archived the glass curtain wall are rare in the country.
Mastering the city's situation is only a step forward in the institutional management of glass curtain wall de-rising. For the glass curtain wall that should be re-evaluated for safety beyond the detection period, the Municipal Construction Bureau will also issue a series of “warning†information – in addition to the announcement of the “overage†list on the website of the Media and Municipal Construction Bureau, the Municipal Construction Bureau will The self-inspection notice will be mailed to the owner of each building, and it is required to conduct self-inspection in time and submit the safety appraisal report within the specified time. In addition, the Municipal Construction Bureau will also submit the “overage†list to the construction bureaus and safety supervision bureaus of each district to remind all departments to jointly supervise and supervise the “overage†glass curtain wall buildings to complete the inspection.
“This process has been implemented for several years and will continue to be implemented.†The relevant person in charge of the Municipal Construction Bureau said that the glass curtain wall safety maintenance implements the owner responsibility system, but from the perspective of citizen safety, the Municipal Construction Bureau will spare no effort to continue. Carry out such institutionalized supervision.
Enacted a “Technical Guide†to support scientific identification
“At present, the glass curtain wall industry has a design life of 25 years, but the key material structure of glass bonding silicone sealant has a warranty life of only 10 years. Some nodes such as the opening fan of the glass curtain wall will also loosen due to long-term use. Deformation." The relevant person in charge of the Municipal Construction Bureau said that the owner of the glass curtain wall is safely maintained. After the glass curtain wall project is completed and accepted for delivery, in principle, it should be inspected every 5 years. After 10 years of use, the structural silicone sealant of different parts of the project should be tested for bonding performance.
However, due to the variety of methods for identifying glass curtain walls, the identification criteria are not uniform, and many owners have doubts and fail to conduct self-inspection in time. In response to such problems, on January 1 this year, the Municipal Construction Bureau and the Municipal Quality Supervision Bureau jointly issued the "Safety Identification Procedure for Bonded Glass Curtain Walls in Xiamen City" ("Procedures"), which is the safety of glass curtain wall in our city. Sexual identification provides a “technical guideâ€.
The “Procedure†draws a “standard line†for the safety of the glass curtain wall, stipulates a number of identification standards, and also proposes three effective identification methods, two of which can achieve non-destructive testing of the glass curtain wall. In this way, it is not only convenient for the owner to carry out scientific appraisal, but also helps the owner to select the appropriate appraisal unit. At the same time, the “Procedure†also provides the identification basis for the appraisal unit to achieve the ultimate goal of reducing costs and innovative ways.
"The 'Procedure' can be said to be the leading standard in the country." The relevant person in charge of the Municipal Construction Bureau told the reporter that the country has not issued relevant standards for the safety assessment of glass curtain walls. Xiamen can be said to be at the forefront of the country.
In addition, the Municipal Construction Bureau also entrusted China Building Materials Inspection and Certification Group to carry out special research on the safety appraisal of glass curtain wall, hoping to provide more convenient and instructive methods for the safety identification of glass curtain wall in our city, with the advancement of technology. And the depth of the research, the cost of testing will be greatly reduced.
Is the glass curtain wall expensive and troublesome?
Municipal Construction Bureau: Some projects only need 5 years of inspection, and two methods can achieve non-destructive identification.
After receiving the public notice, how many self-inspections have been carried out by the owner? Recently, the newspaper investigated this.
