REINFORCING STRUCTURE FOR OPENING
PROBLEM TO BE SOLVED: To provide a solution to a problem of a prior art in accordance with the present invention, that is, to provide a reinforcing structure for an opening capable of meeting increased reinforcing bars in a limited effective area as well as allowing an installation of the reinforcing bars to be easier than that of the prior art.SOLUTION: A reinforcing structure for an opening includes side reinforcing bars and center reinforcing bars. The side reinforcing bars are curved steel bars each having a horizontal part and a ramp part, and are disposed on right and left side surfaces of a concrete beam while securing a predetermined covering, by making four reinforcing bars as one set. The center reinforcing bars are disposed between the side reinforcing bars positioned on the right and left side surfaces. The opening is surrounded with four ramp parts (of four side reinforcing bars) on the side surface sides, and is contained in a closed area formed by all or part of the center reinforcing bars on the cross-sectional center side.SELECTED DRAWING: Figure 1
【課題】本願発明の課題は、従来技術が抱える問題を解決することであり、すなわち、補強鉄筋の設置作業が従来に比して容易であり、しかも限られた補強有効範囲であっても補強鉄筋の増加に柔軟に対応することができる開口部の補強構造を提供することである。【解決手段】本願発明の開口部の補強構造は、側方補強鉄筋と中央補強鉄筋を備えた構造である。側方補強鉄筋は、水平部と傾斜部を有する折り曲げ鉄筋であり、４本を１組として、コンクリート造梁の左右の側面に所定のかぶりを確保したうえで配置される。また中央補強鉄筋は、左右側面に配置された側方補強鉄筋の間に配置される。開口部は、側面側では４つの（４本の側方補強鉄筋の）傾斜部によって取り囲まれ、断面中央側では中央補強鉄筋の全部又は一部によって形成される閉鎖領域の中に収められる。【選択図】図１
