PROBLEM TO BE SOLVED: To position and retain an opening of an embedded object in a state that it is securely brought into contact with a mold surface in a place where concrete surfaces are orthogonal to each other because of beams, slabs or the like of a building and the space between the mold and reinforcing iron bars or the like embedded in the concrete is small, thus securely preventing the intrusion of grout into the opening at the time of the pouring of the concrete, and to easily connect a protective tube of a wiring/plumbing material to a connection part. SOLUTION: The concrete embedded object has a connection part 11, the opening 3, a first contact surface 22 and a second contact surface 32. A corrugate tube is connected to the connection part, and the opening is exposed from the concrete wall surface for pulling out a cable drawn into the corrugate tube. The first contact surface and the second contact surface 32 which are formed of two surfaces orthogonal to each other are continuously brought into contact with two surfaces of the concrete mold which are orthogonal to each other. The opening 3 is formed at the second contact surface. COPYRIGHT: (C)2009,JPO&INPIT |
