Under the typhoon, the wind resistance of building metal roof is concerned

"Du Suri" just left, "Kanu" followed, and the recent typhoon raged, bringing severe tests and huge damage to the building. Last week, Quanzhou Strait Sports Center ceiling color steel plate and heat insulation quilt was torn off by the typhoon, as the May Day Quanzhou concert venue, this news immediately triggered heated discussion among netizens, who are worried about whether the concert planned for August 24 will be postponed.

In bad weather conditions, the roof of the building as the first line of defense against wind and rain, its wind resistance, water resistance and sealing is particularly important. Due to the strong wind speed and sudden change of wind direction, the typhoon puts forward higher requirements for building structure and building materials.

Over the past 45 years, wiskind has been deeply engaged in the metal enclosure industry, providing high-quality products and services for the Lhasa Cultural and Sports Center, Qingdao World Expo City, Qingdao International Convention Center, Yulin Yuyang Airport, Qingdao Guzhen University Gymnasium and other high-quality public buildings in the field of public buildings.

Wiskind roofing system waterproof performance is excellent, in the Zhengzhou Olympic Sports Center project introduced in this article, wiskind also with excellent strength and professional ability, became a strong supporter of its success in the "China Metal Envelope System Engineering Jin Yu Award". At the same time, the wind resistance performance of wiskind roofing system has been strictly tested, which can effectively resist the invasion of extreme weather, and is an ideal green building material.

Zhengzhou Olympic Sports Center, innovative structure show power

As the first project in Henan Province to win the global BIM Award, Zhengzhou Olympic Sports Center has a total construction area of 573,600 square meters, including a stadium, a Class A gymnasium and a Class A swimming pool, which can accommodate up to 80,000 spectators.

The steel structure of its "one and two halls" uses a total of 47,000 tons of steel, which is equivalent to building a "bird's nest". However, unlike the "Bird's Nest" all-steel structure ceiling, the Zhengzhou Olympic Sports Center uses a combination structural system of "triangular giant truss + facade truss + grid + large opening spoke cable grid", which creates excellent strength and rigidity for the building. It can effectively resist the influence of external loads and ensure the stability of the building under various conditions.

Wiskind metal roofing system, safe and stable, wind resistance

The success of the project is not only the excellent structural system, but also the blessing of high-quality building envelope materials. Zhengzhou Olympic Sports Center uses Wiskind vertical locking aluminum magnesium manganese roofing system, a total of about 21,500 square meters. The roof plate is fixed by the aluminum alloy fixed seat through the vertical edge bite, and two EPDM waterproof rubber pads are added under the fixed seat and the sealant is fully coated, so that no perforation can be seen to ensure the integrity of the roof plate, so as to achieve good waterproof effect.

The vertical locking process of plate and plate is completed automatically by machinery, and the connection between the occluding edge and the support can solve the plate stress caused by thermal expansion and cold contraction, and can effectively resist the torsion and displacement under high wind speed.

The length of the Wiskind vertical locking aluminum magnesium manganese roof panel is about 70m, and the panel is transported to the roof installation area in the form of cableway, which reduces the lifting process of the roof panel and the damage of the finished product during transportation. In addition, its lightweight characteristics greatly improve the installation efficiency and greatly reduce the comprehensive cost.

And the aluminum magnesium and manganese used in the plate has considerable strength and good flexibility, which can perfectly realize various design ideas and help Zhengzhou Olympic Sports Center realize the design concept of "heaven and earth, the Yellow River and Tianshui". After the completion of the project, the "two pavilions" is like three islands, and the smooth curved roof lines with the lighting design around the body are like the Yellow River, and the square design of the gymnasium and natatorium on the side jointly presents the traditional cultural concept of China's "round sky and place".

Peroration

Nowadays, the green requirements for public buildings are increasing, and there is bound to be a higher pursuit in terms of its energy-saving technology and equipment. Ceaselessly and innovatively, wiskind will also adhere to the vision of empowering China's manufacturing industry with green and energy-saving new materials and becoming a respected and sustainable enterprise, constantly explore new materials and new technologies, create green, sustainable and intelligent quality projects for customers, and inject lasting power into China's manufacturing industry!
