FOUNDATION FORMWORK STRUCTURE FOR HOUSE AND METHOD FOR CONSTRUCTING FOUNDATION FORMWORK

摘要

To solve the problem in which a conventional foundation formwork is heavyweight and long so that work efficiency in carrying or construction is poor, and work efficiency becomes poorer when reuse work is added; the use of foamed resin materials has been proposed, however, there are problems with installation and removal work.SOLUTION: Inside and outside heat insulation frame plates made of a formed resin material are positioned upright at a certain height from the ground surface while the thickness of a foundation concrete frame body is maintained. The inside heat insulation frame plate is positioned upright at a certain height on a foundation concrete base installed on a concrete ground surface. The lower half part of the outside heat insulation frame plate abuts on an outer end surface of the foundation concrete base, and the upper half part of the outside heat insulation frame plate protrudes from the ground surface. The foundation concrete frame body is formed by concrete installation between the inside and outside heat insulation frame plates.SELECTED DRAWING: Figure 1
