Curtain wall safety modification

In the domestic cities, the curtain wall building has been more and more, the project is more and more big, the corresponding occurrence of engineering quality safety accidents, wounding cases are also seen in the news from time to time, which involves mainly glass curtain wall, glass fracture falling is the main phenomenon, there is a hidden frame glass curtain wall of the glass plate off. Countries in recent years on the wall in such aspects as design, construction, operation and maintenance is put forward, in order to achieve standard architectural curtain wall in construction project application, specifications, clear of all security responsibilities in building curtain wall project, the security problem of domestic large curtain wall project can be effectively controlled, the objective is maximum in making the application of architectural curtain wall.
For the existing building curtain wall that has been built, it is clear that the curtain wall suppliers should do a good job in daily management and maintenance according to the relevant standards and specifications of the curtain wall, and carry out corresponding special inspection and maintenance work to the corresponding service life, so as to eliminate potential safety hazards and ensure the safe use of the curtain wall. But in practice due to the existence of project inspection, maintenance cost is high, the lack of easy and efficient way to check it, a large number of existing architectural curtain wall or in a state of disorder free control, the department concerned has taken a different approach to maintenance and upgrading work, for the safety of the existing architectural curtain wall maintenance experience, which can provide some reference.

Chengdu commerce-residence building project, the project was completed using ~ 1996, 8 layer building, curtain wall window to 500 square meters, mainly for the single 6 mm ordinary coated glass of concealed frame glass curtain wall, due to the use fixed number of year has nearly 20 years, structural adhesive, it should be said that there are potential safety problems, considering the factors of the project party, After consultation, it is proposed to enhance the fixation by adding point mechanical fixing method on the glass plate, that is, drill 4 holes in the 4 corners of the non-tempered glass plate, install stainless steel bolts with large caps through the Angle code, and fix them on the aluminum alloy enclosure frame. It also solves the safety problem caused by the possible failure of structural adhesive to a certain extent.

Of the engineering examples, but said curtain wall structural adhesive should have good bonding performance, long service life, but after all, no one can for more than 10 years of structural adhesive pledged on engineering application, especially the factors affecting the safety of structural adhesive, such as the quality of the structural adhesive, construction of quality problems, the use of the environment problem and so on, Will make a great difference to the service life of structural adhesive, bring hidden curtain wall frame of uncertain safety hidden trouble, so check in the preservation of both the construction curtain wall must cause enough attention.
