Abstract

PURPOSE: To provide a structure of more strength, by additionally providing a reinforcement to the material below a center of gravity of non-quake-proof switchboard.
CONSTITUTION: For a vertical skeleton 1a of the conventional non-quake-proof switchboard frame, to a portion below a center of gravity of the board frame, is firmly secured a shape steel 2 of big section modulus by methods of welding, further with its bottom end secured by a mating to a fundamental material 1b that runs along a floor level of the board. In this way, the reinforcement of the lower part causes a center of gravity to lower its position as compared with that of the standard type, and an increase of the weight can be suppressed as compared with those a strengthening is promoted up to the ceiling part. In addition, because of a lightness of the weight in the top part of the board, in case of vibration due to earthquake, a stress caused in each of the material members can be lessened.
