Safety design of curtain wall

The safety of the building Windows and curtain wall window is the most important points for Windows and doors curtain wall and the connection of structures. The bearing capacity will affect the Windows and doors curtain wall, which may occur from the building structure overall collapse and loss of serious safety accidents, especially during a powerful typhoon influence. The connection point, as the key point of the safety of the window and window curtain wall, it is not only a design problem, but also a quality problem in the construction process. Here, we only discuss the test verification and construction supervision related to the design.

The main purpose of the real sample model test of the door and window curtain wall is to verify the design effect. However, in the current test verification, the test of doors and Windows is basically not able to truly reflect the actual installation and connection of doors and Windows and openings, and the test verification of curtain wall is also incomplete. Therefore, the actual model test of curtain wall facade is not completely true in the aspect of verifying the connection point with the building structure, which should be paid more attention to. In order to make up for this defect, we should strengthen the door and window curtain wall and building structure connection point in the construction process of on-site detection and construction quality supervision. In particular, these connection parts are in a hidden state after the completion of the project construction. It is very difficult to observe in the routine inspection and maintenance process of the normal use of the door and window curtain wall. Once the problem occurs in terms of curtain wall structure, it may cause immeasurable heavy losses and safety accidents.

At present, in the process of engineering construction, the acceptance of concealed works including the connection of door and window curtain wall and structure installation is mostly a mere formality, and there is no strict supervision, which can be reflected in the acceptance record of concealed works of many door and window curtain wall projects. Most of the concealed works recorded only “acceptance” and other words, neither found any problems, nor treatment of the problem of opinion and results. This is a completely impossible phenomenon. The entire construction industry, the legal profession and the government were recently implicated in a potential shortage of steel bars in the construction of a subway station in Hong Kong. In order to ensure the safety of the project, they made a plan to dig up the construction of the existing structure. It is very common and developed digital and information, and we should be introduced in engineering field in the management of a large number of these scientific and feasible means, like aluminium curtain wall, in addition to use written records, we should increase and keep the pictures or video, film and television inspection data.
