Abstract

PURPOSE:To achieve simplification and reduction of field construction and make construction period much shorter by installing a steel framed foundation beam on a steel framed foundation beam supporting base provided at the bottom of excavation and filling concrete into the bottom of the excavation. CONSTITUTION:Excavation is carried out to form a trench and a foundation 4 is formed at the bottom of the excavation. Thereafter steel framed foundation beam supporting bases 1 are installed at specified intervals in a continuing direction of excavation and a steel framed foundation beam 3 is installed between the bases 1, 1 and fixedly secured onto said bases. And then lower sheathings 12, 12 and upper sheathings 13, 13 are provided on both the left and right sides of the base 1 to form a foundation form 2. And concrete 16 is cast into the form 2.
