PURPOSE:To wire systematically telecommunication cables without burying private wiring of the complicated telecommunication cables in a wall, etc., while keeping the strength of a concrete structure. CONSTITUTION:Holes 6 are previously bored in reinforcing bars 5 buried and used in a column or a beam, etc., they are penetrated in the longitudinal direction of the reinforcing bars 5, and the telecommunication cables 7 are passed into the holes 6. When a concrete structure is constructed, one end of each of the telecommunication cables 7 is projected to the outside from a joint section of the reinforcing bars 5. One end of each of the telecommunication cables 7 is connected to a plug socket 3 for connecting the telecommunication cables exposed and provided to the inside of the structure. |
