することが可能になる。In the method of the present invention, it is possible to appropriately increase the mechanical strength of the foundation beam to be constructed by inserting a reinforcing bar at an appropriate pitch into the gap between the plastic foam plate of the special panel and the flat wire mesh at the time of construction. It is possible. (The reinforcing bars are also used as connecting bars for the structural members constructed on the upper part.) Therefore, the foundation beams constructed by the method of the present invention have a mechanical strength equal to or higher than that of the conventional reinforced concrete foundation beams. Since it has strength and does not require assembling and removing the formwork, it is possible to construct a foundation beam with simpler construction and lower construction costs than the conventional method.
