Release date:2017-06-072 Source: Click:93

March 11, 2017, the sixth China Summit Forum of the Safe Application of Curtain Wall was held at the Canton Fair Westin Hotel in Guangzhou by Guangzhou Baiyun Chemical Industry Co., Ltd and China Construction Metal Structure Association (Aluminum Windows, Doors and Curtain Walls Association).

The theme of this summit forum is Climate and the safety of Curtain Wall, Zhao Xian—researcher and professor of China Academy of Building Research, Zhang Jianjun—chief structural engineer of Shenzhen General Institute of Architectural Design and Research Co.,Ltd., RanelOpamin—technical director of ALT Cladding, Inc. / ALT Limited. and Zhang Guanqi—technical director of Guangzhou Baiyun Chemical Industry Co., Ltd. were invited to deliver their speech about this theme.

And here comes the content of their speech.

Zhang Jianjun—chief structural engineer of Shenzhen General Institute of Architectural Design and Research Co.,Ltd

Topic 1: The Perfect Combination between Curtain Wall and Building Structure.


How to combine curtain wall and building structure together perfectly?


1.The standard of structural displacement control

For example, Shenzhen Dayun Central Gym was used  predetermined camber to avoid structural displacement.

2. Make use of the grids of the curtain wall

Such as:Shenzhen Software Industrial Park, which made use of the grids of its curtain wall to meet the demand of building design.

3. Structure design with heavy wind resistance demand

In order to improve the rigidity of structure and weaken the wind vibration effect to strengthen the ability of wind resistance.

4.The structure stability control of curtain wall

Sample project: Entrance hall of Hangzhou Hospital Ningbo City. Its structure stability was greatly strengthened by connecting the curtain wall with the steel structure.

“Owe to the architects’ high demand of curtain wall, which not only raise the level structure engineer and curtain wall designer, also make the buildings suit the weather better and show the beauty of harmony between human and nature. ”


Zhang Guanqi—technical director of Guangzhou Baiyun Chemical Industry Co., Ltd.


Topic 2: Change of the weather and the safe application of construction sealant


Mr.Zhang described the more and more complicated developing trend of climate by listing a lot of data of global climate change during the speech.

Severe typhoon will bring Curtain walls will be badly affected like the falling of glass, the breaking of glass and etc. by severe typhoon.


Why not choose the right sealant under extreme climate?

1. Choosing high performance structural sealant can ensure the safety of curtain wall under high wind pressure.

2. Choosing high displacement performance weather-proofing sealant can ensure curtain wall watertight under high wind pressure.

3. Structural sealant with better quality and stability can ensure the safety of curtain wall under long-term high  temperature .

4. Stain-resistance weather-proofing sealant can ensure the curtain wall clean for a long time.

5. Using high performance structural sealant, high displacement performance weather-proofing sealant and stain-resistance weather-proofing sealant can not only be economical but also make sure of the safety and quality.

One more important thing is Baiyun can offer the whole process technical service.

RanelOpamin—technical director of ALT Cladding, Inc. / ALT Limited.


Topic 3 Delusion of Facade Construction


Ranel Opamin showed his opinion about the most common and unnoticed mistakes on the construction process of curtain wall like the lose efficacy of structural sealant, unreasonable design of anchoring parts, the wrong usage of mounting bracket and etc., which is vital to the safety of curtain wall buildings.

“If lowering the cost by using inappropriate sealing, flame-resistant and adiabatic materials, it will cause a lot of unsafe issues.”Ranel said and he called on everyone on this field to choose right materials, design and build with rigorous working attitude.

Zhao Xian—researcher and professor of China Academy of Building Research


Topic 4: Several problems of the wind engineering design of curtain wall


“The size of one single glass of headquarters of Apple is up to 15 m × 3.3 m≈50 without pillars which is a creative idea and was applied successfully by Chinese glass company!”

How to strengthen the wind resistance ability of curtain wall?

1. Silicone structural sealant must be used on the second sealing of the insulating glass of hidden frame curtain wall. Its width depends on the calculation of wind strength, which should be not less than 7 mm.

2. The window’s area should be ≤ 1.5 and has enough deepness and limit controls for hooks.

3. The thickness of platen should be ≥ 2.0 mm.

4. Isolation strips below the curtain wall and awning at the entrance should be set up .

Though severe typhoon, its wind strength might be 1.8 times than the normal wind resistance standard, just caused a few curtain walls slightly broken. Therefore if we design and build according to the standard, the wind resistance ability of curtain wall would be safe and reliable.
