<p>PURPOSE:To provide a parallel joint member light in weight with high connecting strength by arranging a plurality of connecting surfaces, having curvature equal to an external diameter of a fiber reinforced resin-made pipe, respectively toward the outside, and integrally forming all the connecting surfaces by fiber reinforced resin through a rib. CONSTITUTION:In a rolling stock use bogie frame or the like in which two fiber reinforced resin-made pipes 7, 8 of constituting a side beam, lateral beam, etc., are connected by a parallel joint member 9 to each other by maintaining a parallel condition, the parallel joint member 9 is constituted by arranging two connecting surfaces 1, having curvature equal to an external diameter of the pipes 7, 8, respectively toward the outside, and by integrally molding both the connecting surfaces 1, 1 by fiber reinforced resin through a rib 2. After connecting the pipes 7, 8 to each connecting surface 1 of this parallel joint member 9 through a liquid-state bonding agent, a jig 10 is attached, and after applying a contact pressure to the connecting surface to place the three members in a fixed condition, the members are heated by a drying machine. In this way, the pipes 7, 8 are integrally formed through the parallel joint member 9, thereafter to remove the jig 10.</p> |
