Mechanism to prevent damage of disaster. |
A big exhibition gathers 100,000 people in a day.
There are a lot of victims at the disaster. Fortunately, the building
have been built very strongly today . However, when the disaster is caused in such a place once, or when rumor extends, 、it causes the panic, and furthermore big secondary disaster is caused by that . Therefore, it is necessary to prepare all the ways as safety and fire precautions.

When
you say "Attention! This is the earthquake!!", the dispersion of the glass is worried about
at first.
To take the lighting, the glasses are multiused in the exhibition hall. There are a lot of parts of the roof made by the glass explaining the example of Tokyo Big Sight. The customer worries cracking and dropping of it. Therefore, the glass is made tempered glass. The wire net is put in the glass. The dispersion prevent film is pasted to the surface of the glass. Moreover, room is applied to connected part of the glass so that the shake of the earthquake may be endured. It is necessary to consider the expansion of the glass due to the heat at the midsummer etc. in the design. |
At the Great Hanshin Earthquake,
it is a famous story that the telephone was able to be used though electricity was disconnected. The fire occurs simultaneously when the disconnected electricity is switched on. The reason why the telephone was not disconnected is that there is "Surplus" on interior wiring. In the ideal exhibition hall, the remainder will be given to all electric wires including electric equipment. | |
Watch your step. If the exhibition hall is built in coastal region, it is necessary to prepare in "Liquefaction" at the earthquake. The ground subsides and moves on ground of reclamation it afterwards. Some time ago, the subsidence of Kansai International Airport became a topic.
I think that it was able to forecast beforehand. | |
