BENT REINFORCING BAR WITH BEARING PRESSURE PLATE
PROBLEM TO BE SOLVED: To provide a bent reinforcing bar with a bearing pressure plate fitted at the bent part of the reinforcing bar, and a reinforced concrete structure having the bent reinforcing bar with a bearing pressure plate embedded in the concrete.SOLUTION: A reinforcing bar is bent at any location, and a bearing pressure plate is fitted at the bent part. A bent reinforcing bar 1 with a bearing pressure plate secures a pressure bearing area with a bearing pressure plate 8, such that a bearing stress intensity in a radial direction at a bent part 6 of the reinforcing bar that accompanies tensile force exerted on the reinforcing bar is less than an allowable bearing stress intensity of concrete. Therefore, bearing failure is prevented for the concrete even if yielding tensile force is exerted on the bent part 6 of the reinforcing bar that is not mitigated by adhesion resistance at a linear part of the reinforcing bar.SELECTED DRAWING: Figure 6
【課題】鉄筋の折曲げ部に支圧板を取付けた支圧板付き折曲げ加工鉄筋ならびに支圧板付き折曲げ加工鉄筋をコンクリート内に定着した鉄筋コンクリート構造を提供する。【解決手段】鉄筋の任意の箇所を折曲げ、かつこの折曲げ部に支圧板を取付けた。支圧板付き折曲げ加工鉄筋１は、鉄筋に作用する引張力に伴って鉄筋折曲げ部６に生じる半径方向支圧応力度を、コンクリートの許容支圧応力度以下になるような支圧面積を支圧板８で確保することにより、直線部の付着抵抗による低減がない鉄筋の降伏時引張力が作用する鉄筋折曲げ部６であっても、コンクリートの支圧破壊を防止できる。【選択図】図６
