<p>PURPOSE:To protect the fixing frame from deformation due to irregularities of wall face by securing the fixing frame mounting a wiring fixture to a reinforcing frame with screws, mounting the reinforcing frame and the fixing frame on the wiring fixture fixing holes and then securing the frames thereto with fixing screws. CONSTITUTION:A wiring fixture 1 is secured to a fixing frame 2. Wires wired to wiring fixture fixing holes 50 are then connected with the wiring fixture 1. The fixing frame 2 is then secured firmly with screws to a reinforcing frame 3, thus obtaining a reinforcing frame assembly. The reinforcing frame assembly is then inserted into a protective cover 42, and the reinforcing frame 3 and the fixing frame 2 are secured with screws to the wall face. At this time, the fixing frame 2 contacts at four positioning protrusions 2f, 2g and the opposite inclining faces 2h with the recessed side of the inflated part of the reinforcing frame 3 and a gap is provided between other parts. Since the gap accomodates the deformation of the reinforcing frame 3 even if the fixing screw 20 is tightened firmly, the fixing frame 2 is not subjected to deformation.</p> |
