摘要： PURPOSE:To provide a high strength bolt joint for frictional connection whose coefficient of friction joint is set to more than a specific value and the reluction rate of whose axial force is small by using coating material including titanate potassium in inorganic zinc rich paint as a coating material to the joint of high strength bolt joint for frictional connection. CONSTITUTION:Splice steel plates 2, 2' are arranged on the upper and lower sides of joint steel plates 1, 1' serving as a base material through coating material 4, 4' including titanate potassium fiber in inorganic zinc rich paint. A material having high tension is used for a high strength bolt 3, and a large tension axial force is generated to the high strength bolt 3 by increasing clamping force of the high strength bolt 3, and stress is transmitted as its reaction by means of a frictional force generated by compressive force of the joint steel plated 1, 1'. The layer thickness of the coating material 4 is 50mum to 150mum. Thereby, the coefficient of friction can be set to 0.5 or more, moreover the decrease of the bolt axial force can be made smaller.

摘要： PROBLEM TO BE SOLVED: To provide a hybrid traffic system having a shared track, which can be constructed and maintained by spending only limited financial resources, imposes only low load thereon, and allows many types of vehicles to travel therethrough. SOLUTION: The hybrid traffic system having the shared track is comprised of a ladder type assembly; sound insulation walls 6A, 6B; and rails 9A, 9B. The ladder type assembly is formed of concrete foundation sections 5A, 5B on which tire track surfaces 7A, 7B are formed in a traveling direction in a manner being opposed to each other; large-diameter conduits 2A, 2B embedded in the concrete foundation sections 5A, 5B, respectively, and arranged in the traveling direction in a manner being opposed to each other; and small-diameter conduits 3 (3A, 3B, etc.) connected to the concrete foundation sections 5A, 5B so as to bridge a gap between the same. The sound insulation walls 6A, 6B are erected from side portions of the concrete foundation sections 5A, 5B, respectively. The rails 9A, 9B are laid on step portions 8A, 8B formed at ends of the tire track surfaces 7A, 7B, respectively. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PURPOSE:To contrive the increase of braking power of a train by lowering a pair of right and left brake shoes from the bottom part of a rolling stock toward the inside in the top part of a rail or the like and pressing each shoe to an inner side surface in the top part of each rail so as to obtain the braking power. CONSTITUTION:In case of braking a rolling stock running on a rail 15 through a wheel 9, first a lift cylinder 3 is moved lowering, and a pair of right and left brake shoes 1 are lowered between positions, opposed facing to inner side surfaces in the top part of the rail or the like, through a piston rod 5. Successively, actuating a brake cylinder 2, each shoe 1 is pressed almost at a right angle to the inner side surface in the top part of the rail or the like through a push rod 4, and braking power is obtained by friction between this shoe 1 and the rail 15. This braking power is generated to a degree not exceeding a cross pressure of the wheel.

摘要： PURPOSE:To increase the coefficient of friction for lessening the lowering rate of bolt shaft force by applying an epoxy resin plate based on grass fiber unwoven cloth to an insulating plate to be inserted between the friction faces of an insulating high strength bolt joint. CONSTITUTION:First the fastening force of a high strength bolt 33 is enlarged to generate large tensile axial force, and stress is transmitted through frictional force caused by compressive force generated in a joining steel plate 31 (base metal) as the reaction force to the above tensile force, and an insulating high strength bolt joint is composed in the above structure. The surface of the axial part of the high strength bolt 33 is covered with insulating material 35. Next, an epoxy resin plate 34 based on a grass fiber un woven cloth having the thickness from 0.1mm to 0.7mm between a joining steel plate 31 and a splice steel plate 32 to insulate conductivity. In addition, the similar process is executed between the splice steel plate 32 and the other joining steel plate 31 to insulate between the above steel plates. Thus the insulated high strength bolt joint which has high insulating ability, the coefficient of friction being above 0.4 and the bolt axial lowering rate being above 90% can be formed.
