摘要：PROBLEM TO BE SOLVED: To provide a precast concrete pole having an increased tensile strength and a method of joining the precast concrete pole. SOLUTION: In this precast concrete pole 1, PC steel members 7 each comprising a plurality of pieces are disposed on the insides of the column main reinforcements 5 of a precast concrete pole body 2, respectively. The upper parts of the PC steel members 7 project a proper length from the top end of the pole. The lower part thereof projects a proper length into a sleeve 10 disposed on the lower part of the precast concrete pole body 2. Insertion holes 4, 19 for inserting crimpingly joining cables 20, 21, respectively, are vertically formed through the center part of the precast concrete pole body 2. Beam joining jaws 3, 14 project from the upper side surface of the precast concrete pole body 2. COPYRIGHT: (C)2009,JPO&INPIT
