PURPOSE:To construct a retaining wall without the use of sheathing boards by a method in which metal form materials having claws on their sides are fabricated to form an axial set, a metal net is hooked on the inside claws of the axial set, and concrete is placed into the mutually facing metal nets. CONSTITUTION:Lower horizontal parts 7, struts 8, and upper horizontal parts 9. made of metal form materials having plural claws 6 and a lip groove-shaped cross section, are fabricated to form an axial set 2. The axial set 2 is then erectly supported on the concrete foundation 1 by means of a tembering work consisting of beams 3, slant materials 4, and angle materials 5. Then, metal nets 17, e.g., wire laths, etc., are hooked on the inside claws 6 of each axial set 2, and concrete 20 is placed into the spaced set with iron bars 19 between the metal nets 17. Since the metal nets 17 can play the part of sheathing boards simply by being hooked on the claws 6, the time taken for fabricating the form materials can be shortened. |
