PC STEEL PROTECTIVE SHEATH
To provide a short pipe structure connected to a grouting hose for grout injection/exhaust to ensure concrete cover thickness of a PC steel protection sheath with an exhaust port.SOLUTION: A PC steel material protection sheath 1 comprises a cylindrical sheath body 2 into which a PC steel material is inserted and grout is injected, an exhaust short pipe insertion hole part 5 opened at a position to be a circumferential top part of the sheath body 2 when the grout is injected, and an exhaust short pipe 10 which is connected to the exhaust short pipe insertion hole 5 at one end, extends in a direction not parallel to the axial direction of the sheath body 2 and not vertically upward, and is connected to the exhaust grout hose 56 at the other end.SELECTED DRAWING: Figure 1
【課題】コンクリートのかぶり厚を確保する。【解決手段】ＰＣ鋼材保護シース１に、内部にＰＣ鋼材が挿入され、グラウトが注入される筒状のシース本体２と、グラウトが注入されるときの、シース本体２の円周方向頂部となる位置に開口された排気短管挿通用孔部５と、一端が排気短管挿通用孔部５に接続され、シース本体２の軸方向に平行でない方向で且つ鉛直上向きでない方向に延びて他端が排気用グラウトホース５６に接続される排気短管１０とを設ける。【選択図】図１
