To provide a leakage prevention tool, upon exhaust of ready-mixed concrete from a drum of a concrete mixer truck or after its exhaust, preventing the leakage of ready-mixed concrete, cleaning water or the like, e.g., from a gap between the back edge part of the outer circumference of the drum and a scoop or a sheet made of synthetic resin arranged around the back edge part at the outer circumference of the drum.SOLUTION: A ready-mixed concrete leakage prevention tool 1 mounted on the outer circumferential edge part on the side of the exhaust port in the drum of a mixer truck is composed of: a leakage prevention tool body 2 extending almost in an arc shape in a longitudinal direction; and a locking member 3 connected with both the edge parts of the body. The leakage prevention tool body 2 includes: a base member 21 whose cross section slid with the outer circumferential edge part of the drum has an almost rectangular shape; and a guard member 22 extending in an almost vertical direction from the base member 21. The locking member 3 includes: a locking member body 31; and a locking part 32 for suspending the concrete leakage prevention tool arranged at the edge part of the locking member body 31.SELECTED DRAWING: Figure 1
【課題】コンクリートミキサー車のドラムから生コンクリート排出の際、又は排出後に、ドラム外周の後端部と、ドラム外周の後端部の周囲に配置しているスクープや合成樹脂製のシートなどの隙間から生コンクリートや洗浄水等が漏れ出すことを防ぐ漏出防止具を提供する。【解決手段】本発明の生コンクリート漏出防止具1は、ミキサー車のドラムの排出口側の外周端部に装着する生コンクリート漏出防止具1であって、長手方向に略円弧状に延伸している漏出防止具本体2と、本体の両端部に連結した係止部材3とから構成し、漏出防止具本体2は、ドラムの外周端部と摺動する断面が略矩形であるベース部材21と、ベース部材21から略鉛直方向に延伸するガード部材22とを備え、係止部材3は係止部材本体31と係止部材本体31の端部に配置したコンクリート漏出防止具を吊り下げるための係止部32とを備えること、を特徴とする漏出防止具1である。【選択図】図1
