Why won’t this kind of house collapse even in earthquakes? Take it apart to see more clearly?

Japan, which suffers from frequent earthquakes, is recognized as the world's number one earthquake-resistant country

Although Japan has suffered heavy losses in previous strong earthquakes

most of them have survived. High-rise buildings

The materials used in building houses

Japanese architecture is also particularly particular about the selection of materials. For example, bricks and tiles, which are often used as the main building materials in Europe and China, are now almost nowhere to be found in Japanese architecture. "The Great Kanto Earthquake in 1923 proved that brick-structured buildings are not earthquake-resistant. Since then, brick-structured buildings have almost no longer been used in Japan, and have been replaced by reinforced concrete structures supplemented by lightweight wall materials." Construction industry experts believe that, Buildings with this structure are both safe and earthquake-resistant and energy-saving.

Light steel structure

Most Japanese buildings adopt rigid structures, which greatly reduces shaking. For example, when a major earthquake of magnitude 7 or above occurs, a building with a flexible structure will generally shake about 1 meter, while a building with a rigid structure will only shake 30 centimeters.

Wood Structure

In order to improve the earthquake resistance of traditional wooden buildings, ordinary Japanese houses adopt a box design - when an earthquake occurs, the whole house will roll over and will not be damaged. Professional and technical personnel will also regularly assess the seismic reinforcement levels of private houses, and the government will provide appropriate subsidies and incentives to residents as appropriate.

Using Rubber

Japanese architects commonly use rubber to improve the earthquake resistance of buildings. For example, there is an earthquake-proof structure apartment in Tokyo, Japan. Although it is 93 meters high, its outer periphery uses newly developed high-strength 16-layer rubber, and the central part of the building uses laminated rubber of the natural rubber system. In this way, when an earthquake with a rupture degree of 6 occurs, the stress on the building can be reduced to 1/2.

Japan invented earthquake-resistant houses, built with foam plastic

Foamed polystyrene is becoming more and more popular as a material because houses built with it are highly earthquake-resistant and cheap , fast and thermal insulation and other advantages.

Japan Dome House has been selling Styrofoam houses in Japan for 15 years, but demand for lightweight homes began to soar last year. In April 2016, Japan's Kumamoto region suffered a 7.0-magnitude earthquake, killing 49 people and injuring 3,000 people. More than 44,000 people were evacuated after their houses collapsed or caught fire, and many had to live in temporary housing. But there was one village that did not suffer much damage. The houses here are composed of 480 densely packed dome houses, built by the Japanese Dome House Company.

The Japanese company has been touting the earthquake resistance of its lightweight foam homes for more than a decade. The dome house, made from ultra-lightweight foam plastic fragments glued together, weighs only 80 kilograms and is highly resistant to earthquakes due to its shape and the fact that it does not require beams or columns. Now, the company has begun developing a new generation of foamed polystyrene materials that are stronger and highly insulating than ordinary materials.

Such a house only takes three people a week to build, and the price ranges from 7 million yen (approximately 430,000 yuan) to 8 million yen (approximately 490,000 yuan). The house has an area of ??approximately 387 square feet (approximately 36 square meters) and a height of 3 meters. Because the material is foam plastic, the house will not rot or rust, and there is no need to worry about termite infestation.

Another advantage of this kind of house is that it can be highly customized according to the customer's requirements. You can make it a permanent residence, guest house or hotel. Because they are cheap, they can be used as temporary housing during disasters.
