PURPOSE:To avoid the waiting state of a carpenter by forming the inserting groove of a girder-eave ceiling material along the outer circumferential section of the opening section of a main body, forming a wiring through-hole to an external wall section facing the upper side of the girder-eave ceiling material and installing an outlet box functioning as the corbel of the girder-eave ceiling material. CONSTITUTION:One end of a conduit tube 3 is inserted into the wiring through- hole 11 of a main body 1 first, and the conduit tube 3 is deflected and inserted into the wiring through-hole 11, to which the other end must be connected, of the main body 1. The conduit tube is adjusted so as to be positioned in specified height at approximately the central section of the conduit tube 3, and can be fixed by using a screw, a nail, etc. Consequently, the conduit tube 3 as a continuous length can simply be mounted even by one carpenter. Since inserting grooves 10, 30 as the corbels of a girder-eave ceiling material 4 are formed up to that time, the carpenter craftsman need not wait until an electrical work craftsman completes the mounting work of an outlet box and the conduit tube, and the carpenter craftsman can set up the girder-eave ceiling material 4 continuously. |
