<p>PROBLEM TO BE SOLVED: To obtain a lid installation-type U-shaped structure whose working efficiency at a site is high, by which a working environment is made good and by which a posterior cleaning operation and a finishing treatment are executed easily. SOLUTION: A structure is composed of a U-shaped structure body 2 and of a lid body 3, and it is used to house cables 9 and to branch and/or connect them. At this time, one or more branch cutout parts 10 through which branch wires 9a of the cables 9 are passed are made at the upper end of at least one sidewall 6 along the laying direction of the cables 9 at the U-shaped structure body 2. Thereby, when the cables 9 are branched, the branch wires 9a are passed through the branch cutout parts 10, the lid body 2 is just put on the U-shaped structure body 2, and the cables 9 can be branched.</p> |
