PURPOSE:To stably fix an electric apparatus so that it is protected from the effect of an external force such as an earthquake by fastening a foundation bolt and a foundation plate with a bolt and securing a fixing metal member to be linked with an electric apparatus to the foundation plate. CONSTITUTION:A bolt 6 is inserted into a taper hole in a foundation plate 5, and screwed into a foundation bolt 4 to position and fix the bolt 6 to to the plate 5. After an electric apparatus 1 is set at a given position, a fixing metal member 7 is secured to the plate 5 by welding. If the position of the bolt 4 and the installation position of the apparatus 1 are out of location, the size of a hole 9 can compensate it. Therefore, positioning is ready. This permits each bolt to equally bear its share of the load against a side slipping force. Therefore, the electric apparatus can be stably fixed with bolts having an optimum diameter and number. |
