As we all know, Japan is located in the Pacific Volcano and Seismic Belt, where the Pacific Plate and the Eurasian Plate squeeze and collide. According to statistics, there are thousands of earthquakes in Japan every year. Faced with this natural situation, last year, Japan spent 400,000 to 500,000 yuan to build a new styrofoam house (Japan Dome House) that can withstand a magnitude 7 earthquake.
This styrofoam house is designed with ultra-lightweight polystyrene foam parts and is a dome-shaped house that looks a lot like a yurt. So why can this house withstand a magnitude 7 earthquake? The main reason lies in the material used in this house. It does not use ordinary styrofoam, but a new generation of materials developed using proprietary technology. It is better than those used for edible containers orPackaging The foam material is much more stable.
In principle, the beads in conventional polystyrene expand by about 50% to 60% of the original size of the styrene monomer, thereby absorbing a large amount of oxygen, resulting in a stable building Poor sex. To ensure stability, scientists developed a method to expand the styrene monomer by only about 20% and minimize oxygen absorption. This makes the material stronger than traditional foam while maintaining its insulating properties.
Although this houseThe materials used are very simple, but its price is not cheap. A domed styrofoam room can be constructed in a week using modular combinations, with a room area of ??approximately 36 square meters and a height of approximately 3 meters. Although it is small and does not have any columns or beams, its cost is not cheap. The cost of building such a small house is about 7-8 million yen (approximately RMB 430,000-490,000), and the total weight is about 80 kg.
But it is really worth the money. In addition to being able to withstand a 7-magnitude earthquake as mentioned before, it will not rot or rust, and it is not infested by termites. Danger. The most important thing is that it is customizable, allowing users to incorporate their own unique ideas into the house, so you can also become a designer.
However, this dome styrofoam house was not accepted by the Japanese people at first, because it was difficult for people to accept it and abandon traditional houses. But in April last year, Japans Kumamoto Prefecture was hit by a magnitude 7 earthquake, causing severe damage. However, the Jiuzhou Village next door did not suffer any damage. The reason is that they used this dome foam without any columns or beams. house.
So, many people in Japan have now accepted this house, which is used as permanent residences, hotels, etc., and also as temporary housing during disasters.
