There are a lot of earthquakes of Japan where we live. When a large-scale earthquake happens in Japan, I can get goods from the Self Defense Forces and the volunteer. However, I see the hardship of securing of the bed. the victim take time to the restoration of the house. Then, we thought about 'Three rules' that used the familiar one. 'Three rules' is the one that the room can be made if there are three sticks. Moreover, it doesn't originally prepare, and because it only has to be a long stick such as the washing poles that remained after the earthquake, it is easy to obtain.
It stuck to '3' in 'Three rules' all. One room can be done only by leaning three long sticks like the triangle. Moreover, the large room can be made by building the beam across the roof. The number of rooms can be changed by how to build the beam. We obtained two to the shelter for the emergency. First of all, it thought about the use of the material that shed moisture such as the vinyl sheets as surpassing 1 and rain. The room shut out the rain on the inside in covering with the thing made like the bag such as the garbage bags on after it had tucked it with the vinyl sheet. Moreover, the space between rooms covered with the vinyl sheet from the beam.Moreover, 2 and a private space became possible by use the vinyl sheet that attached the color. In addition the rest room and the bath, a private space can be made from this. I think that this 'Three rules' is rules that not only Japan but also any country when the earthquake happens can use.
