PURPOSE: To obtain a reinforced concrete structure, in which rainwater, etc., are not accumulated and a scaffolding is not brought to an unstable state even when an operator gets on the scaffolding and in which a member for lightening, wherein breaking, etc., are not generated, is buried.
CONSTITUTION: Slab lower-end reinforcements 1a, 1b are arranged onto a form bottom plate 6, and a lightening member 41 is disposed at a proper position in forms. Slab upper-end reinforcements 2a, 2b are arranged, but the lightening member 41 is not broken because the lightening member has high rigidity by the action of a face bar 41a even when an operator gets on the lightening member 41 and conducts operation at the time of the arrangement of the reinforcements. Accordingly, even when the foamed lightening member 41 is cracked, the face bar 41a is used, thus preventing breaking from the cracking section of the lightening member 41. The face bar 41a obstructs the absorption of moisture, thus generating no problem, in which rainwater, etc., are accumulated in the foamed lightening member (b).
