FIXING STRUCTURE OF HEAT-INSULATING MATERIAL AND WIRING BUNDLES IN RAILROAD VEHICLE STRUCTURAL BODY, AND RAILROAD VEHICLE STRUCTURAL BODY PROVIDED WITH THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a fixing structure of a heat-insulating material and wiring bundles in a railroad vehicle structural body, and a railroad vehicle structural body provided with such a fixing structure that allow easy attachment and detachment of the heat-insulating material and the wiring bundles to/from a surface of each structural body or pedestal frame constituting the railroad vehicle structural body, within a short work time.;SOLUTION: A fixing member 100 for fixing a heat-insulating material 50 and wiring bundles 230 to a surface of each structural body or pedestal frame constituting a railroad vehicle structural body 10 is fixed to fixing rails 25 provided to the railroad vehicle structural body 10 by using fixing portions 110 provided to both end portions of the fixing member 100 along the longitudinal axis. Each pinching portion 130 of the fixing member 100, which is formed in a cylindrical shape, holds the wiring bundle 230 by a restoring force at the time of its elastic deformation, and holding portions 120 of the fixing member 100 hold the heat-insulating material 50 by pressing the heat-insulating material 50 against a vehicle body inner surface. Because the restoring force of the fixing member 100 at the time of its elastic deformation is utilized, the heat-insulating material 50 and the wiring bundles 230 can be fixed to the railroad vehicle structural body 10 more easily, compared to conventional fixing structures of both.;COPYRIGHT: (C)2011,JPO&INPIT
