I introduce you today, this is the site of bar arrangement before reinforced concrete construction. This is to make the foundation of wooden house.
These iron bars are arranged based on the regulation. The regulation provides that arrangement method, separation, joint lap length and diameter of bar.
The diameter of the bars is 10 - 13mm. The bars are reused iron from scrapped automobiles and others.
The inspectors do precise check like typical Japanese. Sometimes it's too much.
However, we follow the regulation and after the construction, Japan Inspection Organization who is authorized by Ministry of Land, inspects the conditions. We have to pass the inspection.
Recent years, most of the Japanese wooden houses have this type of concrete foundation. By the way, 70-80% of detached houses (for a family) are wooden in Japan. We still like the house made of wood.
