Zusammenfassung: | PROBLEM TO BE SOLVED: To reduce a height of timbering, and easily construct a roof frame by excavating the ground, and forming the angle-shaped ground by banking according to a shape of the roof frame and an installing position of a footing part. SOLUTION: The ground is excavated according to a shape of a roof frame 3 whose central part is high and peripheral footing part is low so that a peripheral part becomes deep and a central part becomes shallow, and angle-shaped surplus soil 1 is formed, and timbering 2 is arranged on the angle-shapes surplus soil 1, and a roof frame 3 is integrally assembled on the timbering 2. Afterwards, the timbering 2 is removed, and the angle-shaped surplus soil 1 is excavated/removed, and construction work of the roof frame 3 is completed. When an installing position of the footing part of the roof frame 3 is high, it is better that angle-shaped banking is formed on the ground or a peripheral part is excavated and banking is formed in a central part. Therefore, a height of the timbering 2 is reduced, and labor and time to install and disassemble the timbering 2 can be sharply reduced, and the roof frame 3 can also be safely assembled in a lower position. |
