PURPOSE:To shorten the period of construction for concrete foundation by a method in which plural metal struts with claws are erected on the bottom of an excavated trench, metal nets are attached to between the metal struts by bent claws, and concrete is placed into the metal nets. CONSTITUTION:Plural metal struts 1 having plural claws on their sides are erected on the bottom of an excavated trench A of a given shape, metal nets 3 are attached to bent claws 2 between the metal struts 1, and concrete 5 is placed into the metal nets 3. Thus, since the assembly and disassembly of formwork as in the conventional methods can be omitted, the construction method can be simplified and foundations of necessary size and shape can be simply constructed because the work is not governed by the shape and size of the foundation. |
