Weight steel frame stake construction
	Structure calculation is carried out on the basis of the result of foundations investigation. There are various methods supporting a house. Since 5-12m has many stratums strong a Nagoya in the city A stake is struck to the stratum. But it is from Nagoya Castle up to Atsuta Shrine. The very good stratum has spread. a boundary [ this ] -- north -- the sands -- well -- well . west -- the sands -- well -- well . Gradually, an east becomes good and goes. South becomes bad suddenly and goes. Let's consult with a designer well. The left photograph has struck the stake.
	The method supporting a house If a strong stratum is in near The direct foundation is made. About 1m, if it is, it will be called foundations improvement. Cement is mixed with the ground and it hardens. Or it is called wrapul concrete. It digs to a strong stratum and concrete is struck. As for a left photograph, a stake appears.
	There are various kinds also in a stake. A left photograph is called PHC pile and is a very strong stake. This stake is struck to a strong stratum.
	A left photograph is called variant pile. It is the stake which enlarges friction and supports a house. The length which bears the weight of a house strikes this stake.
