上述したようにして、ＲＣ構造により、分割したフラットデッキ１２上にコンクリート１３を打設してコンクリート床１１が構築されるが、以下のような問題があった。   As described above, the concrete floor 11 is constructed by placing the concrete 13 on the divided flat deck 12 by the RC structure. However, there are the following problems.

（１）通し鉄筋１７のフラットデッキ１２への溶接不良により、フラットデッキ１２が焼き切れるおそれがあった。
（２）通し鉄筋１７では、コンクリート１３からのフラットデッキ１２の剥離防止効果が不十分な場合があった。
（３）フラットデッキ１２同士は、角材１６上に突き合わされているのみであるので、コンクリート１３のノロ漏れが生じて、美観上、好ましくない。 (1) The flat deck 12 may be burned out due to poor welding of the through-bar 17 to the flat deck 12.
(2) In the case of the threaded reinforcing bar 17, the effect of preventing the flat deck 12 from peeling from the concrete 13 may be insufficient.
(3) Since the flat decks 12 are only abutted on the square member 16, the leak of the concrete 13 occurs, which is not preferable from an aesthetic point of view.

従って、この発明の目的は、フラットデッキの焼き切れのおそれがなく、コンクリートからのフラットデッキの剥離防止効果が高く、しかも、コンクリートのノロ漏れのおそれがない、フラットデッキプレートの剥離防止金物を提供することにある。   Accordingly, an object of the present invention is to provide a flat deck plate peeling prevention metal which has no fear of burnout of the flat deck, has a high effect of preventing the flat deck from peeling off from the concrete, and has no risk of leakage of the concrete.
