The utility model discloses a concrete preformed hole plugging device, including the precast concrete piece with fix the reinforcing bar on precast concrete piece upper portion, the size and the preformed hole size phase -match of precast concrete piece, the reinforcing bar is U type structure, is being used for the kink of the fixed reinforcing bar of block respectively at two tops of U type structure. The portion of buckling is reserved to device itself for the fixed reinforcing bar of block is connected more firmly, has avoided the potential safety hazard, device itself comprises higher reinforcing bar and the concrete of intensity simultaneously, places in the preformed hole, effectively strengthens the intensity of preformed hole, do not need subsequent coating operation of paining, save the cost. 本实用新型公开种混凝土预留孔封堵装置，包括有预制混凝土块和固定在所述预制混凝土块上部的钢筋，所述预制混凝土块的尺寸与预留孔尺寸相匹配；所述钢筋为U型结构，在U型结构的两个顶部分别为用于卡合固定钢筋的弯折部。装置本身预留弯折部，用于卡合固定的钢筋，连接比较牢固，免除了安全隐患；同时装置本身由强度较高的钢筋和混凝土构成，放置在预留孔内，有效加强预留孔的强度；不需要后续的涂抹涂料操作，节省成本。
