Abstract

PURPOSE:To enhance both lateral rigidity and vibration-damping-capacity, by fixing both a clamp plate, to which a track bed is fixed via a pair of projections for insertion of the lower part of the track bed, and a base plate to the machinery. CONSTITUTION:A track bed 1 is inserted into a pair of projections 8 and 8 of a clamp plate 7 and is fixed to both a base plate 6 and the clamp plate 7 by means of bolts 5 and 9. In this state, both base plate 6 and clamp plate 7 are fixed to a base 4 by means of a bolt 10. At this time, a lateral load is born by both bolt 5 and projections 8 of the clamp plate 7, while the vibration is absorbed by a minute slip occurring at a space between the base plate 6 and the clamp plate 7 or between the clamp plate 7 and the track bed 1, all of which are fastened to each other by means of the bolts 5, 10, and 9. Accordingly, both rigidity to a lateral load and damping capacity to the vibration can be enhanced.
