Steel structure is actually a lightning protection net bird's nest

Steel structure is actually a lightning protection net bird's nest, water cube can fight a magnitude 8 earthquakeIn "steel" of the national stadium (bird's nest), can withstand the test of lightning? In the recently published "hi-tech Olympics ─ ─ analytical ideas of science and technology of Beijing Olympic Games a book reveal in detail the" bird's nest, water cube, "lightning protection, seismic technology. Revealed in the book, the "bird's nest" appearance is smooth, no ordinary of lightning rod on big construction, in fact, it's the whole "steel" constitutes the ideal "cage lightning protection net".

Steel Structure Warehouse http://www.jingtabuilding.com/steel-structure-workshop.html of lightning protection does not hurt the audience

Revealed in the book, "bird's nest" design of the lightning protection is not mysterious, just make full use of the favorable conditions of building structure itself. Designer metal roof will be the "bird's nest" of the steel components, steel structure and reinforced concrete reinforcement, effectively connected by welding way, so that the "bird's nest" itself is formed a huge lightning protection network, the "bird's nest" of the steel structure has been a huge receiving lightning device, can put the lightning quick import underground.

"Bird's nest" steel structure receives the lightning itself, will not affect the safety inside the "bird's nest"? Explained in the book, in order to prevent lightning damage to human body, venues, my wife can touch place, such as steel structure, do the special handling, offset the effect of lightning to the person, never hurt people; At the same time, the "bird's nest" in almost all of the devices are connected to the lightning protection network for reliable, ensure that lightning coming moment, smooth will be huge current through the ground, to ensure the venue itself, equipment and personal safety.

Water cube can fight a magnitude 8 earthquake

Appearance of bubble water cube, no sharp lightning rod shaft near the venue, the bubble can also lightning protection? Revealed in the book, the original underground and basic part of the water cube is a reinforced concrete structure, the floor is steel space frame, steel welded together, the rack and the underground in reinforced concrete is formed a cube of cage, the lightning protection network structure material completely on its own, as a wire connected to the ground, no longer separate lightning rod, can make the thunder into the underground.

The most special is, the water cube and effeminate, there are 12000 bearing nodes, these nodes can evenly bear the weight of the building. At the same time, the water cube to Shanghai underground reinforced concrete structure and fully welded together, the whole venue as a whole, to fight against a magnitude 8 earthquake standards.

1 the "bird's nest" surface no general lightning rod on big construction. Its steel structure are connected through a welding way, being attacked by a lightning, Steel Structure Warehouse has become a huge receiving lightning device.

2 in order to prevent lightning damage to human body, venues, my wife can touch place, do the special handling, offset the lightning effects on people, won't hurt people.

3 "bird's nest" in almost all of the devices are connected to the lightning protection network for reliable, thunder and lightning coming moment, smooth will be huge current through the ground, to ensure the venue itself, equipment and personal safety.

"Bird's nest" national stadium steel structure

"Bird's nest" national stadium steel structure first hoisting successsteel structure disgn With the construction of the difficulty of the national Steel Structure Building disgn Has experienced a long process, from concept design to design, from the roof can be opened, to cancel the open roof, roof openings. The "bird's nest" scheme of weaving shape steel structure modelling is unique, but greatly improve the construction difficulty accordingly. Maximum cross section truss column x 20 m, 25 m height is 67 m, single heaviest cross 600 tons. Main truss height of 12 m, the double cross through the largest span of 258.365 m, component size, heavy weight monomers. To decrease the difficulty of components assembled truss column USES lie to spell, will use the main truss flat spelling (inner ring main truss stand spell except), so that component of the vertical lifting, hoisting in place extremely hard and high stability. And facade secondary structure weight is relatively small, but oddly shaped, and tilt outward, operation platform, and it is difficult to set and stability measures.
Shanghai treasure smelting construction national stadium project department would make each project is the project's concept, all up and down together, overcome difficulties, to overcome technical difficulties one by one, make sure that the first piece of truss column hoisting on schedule, to treasure smelting construction fired the first shot in the construction of the national stadium, also treasure smelting Steel Sheds http://www.jingtabuilding.com/steel-sheds.html of the construction of the brand to a heavy sum.
