摘要： PROBLEM TO BE SOLVED: To provide a rail rolling stock capable of absorbing impact energy. SOLUTION: In a body of the rail rolling stock comprising a hollow shape 40, an annealed hollow shape is used for the hollow shape 40 constituting an end of a base frame 30. A longitudinal direction of the hollow shape 40 is that of a body. The base frame 30 is formed by arranging a plurality of the hollow shapes in a width direction, and joining them by friction agitating joint. When impact load is applied, the hollow shape of an end is deformed in the form of a bellows, and impact force is absorbed. At this moment, the impact force is applied on a friction agitating joint part, but since it is the friction agitating joint, cracks do not occur, and the hollow shape is not prevented from deforming into bellows.

摘要： PROBLEM TO BE SOLVED: To improve the outer looking of side groove body in the outer side of a railway vehicle, work efficiency and production accuracy by removing a pier panel on the outer side thereof construction a continuous window by a hollowwise extruded shape, eliminating the part on the inner side of the vehicle at the position where the continuous window is not constructed. SOLUTION: Window members 15 are mounted at a window operating part 19. The members 15 are arranged continuously to the longitudinal direction of vehicle body to thereby form a continuous window 14. A side groove body 2 is composed of a screen part 6, waist part, pier panel 8 and a vehicle body end general part 9. A part of the general part 9 existing at the height at which the window member 15 is mounted is a vehicle body special part 20. In the panel 8, no rib is used to thereby secure a s pace into which the member 15 is inserted. In the special part 320, any rib and part, forming protrusion on the inner side of the vehicle, of a vehicle inner side surface plate are eliminated to thereby ensure the maximum space on the inner side thereof. Accordingly the work efficiency and production accuracy are improved.

摘要： PROBLEM TO BE SOLVED: To provide a function to insulate heat and insulate noise in addition to rigidity and the strength of a body structure and to reduce the weight of car body, simplify attachment at heat insulation material and to reduce the production of noise in a rolling stock by a method wherein a honeycomb panel is attached to a plate part between the ribs of a section by means of an adhe sive. SOLUTION: In a waist part 2, by using an adhesive 13, a honeycomb panel 12 is joined with each of plate parts 7 between a sheet belt 5 and a rib 8, between the ribs 8 and 8, and between the rib 8 and a side beam 6. In which case, the thickness and the material of the honeycomb panel 12 are considered to provide target rigidity and strength by forming integrally with a section consisting of the plate part 7 and the rib 8 at the waist part 2. The honeycomb panel 12 is formed of a non-metallic material, for example, a composite material. The honeycomb panel 12 comprises two face plates; and a hexagonal core, arranged between the two face plates, and contact parts are interjoined through an adhesive.

摘要： PURPOSE:To reduce a vertical variable and to enhance vehicular passing by connecting the lower portions of bays with a pin and by expanding a gap between the upper portions to insert a spacer and by forming a camber for upwardly providing an entire bridge with a projected shape. CONSTITUTION:The lower portions of adjacent bays 2 are pivotally connected to each other with a connecting pin 8. A hydraulic jack 9 is provided between the upper portions. A gap is expanded to provide a spacer 10 in the gap. A camber is formed to have an emergency bridge 1 upwardly projected under a deadweight state from a line straightly connected between supporting points at both banks. Vertical deflection due to a maximum passing load is evolved above and below the line straightly connecting between the supporting points at both the banks under the deadweight state. Thus the maximum value of an upward and downward variable is decreased; and horizontal movement at the supporting points is reduced, enhancing vehicular passing.

摘要： PURPOSE:To enhance pressure resisting strength and reliability in strength by using a brazing aluminium allay laminated panel capable of weld joining as a floor plate material of an underframe, and arranging a core material rigidity reinforcing member inside of a core material in a joining part of this core material and a lateral beam. CONSTITUTION:In an underframe structure where a floor plate 7 composed of a laminated panel is spread all over an upper surface of a lateral beam 5 between bolsters among an overall length of an underframe, the laminated panel is constituted by joining members integrally together by brazing by interposing a core material and a joining member arranged in the outer peripheral part between surface materials integrally formed of two sheets. Thin pipes 14 being a rigidity reinforcing material are arranged inside of a honeycomb-shaped core material 12 in a part where the floor plate 7 and the lateral beam 5 come into contact with each other, and thes thin pipes 14, and the core material 12 are joined together by interposing a blazing material or an adhesive 16 between both. The lateral beam 5 and the laminated panel are joined together by brazing one surfaces of thin pipes 15 to reinforce rigidity of the core material 12 swelling out from a flange width of the lateral beam 5 to a flange end part of the lateral beam 5.

摘要： PURPOSE:To prevent a floating body in the up-stream side from sinking, in a power boat supporting a floating bridge used in a river or the like against the stream of river. CONSTITUTION:A pad plate 3 horizontally contacting against a floating body 1 and a pushing bar 4 pressing down the floating body 1 are fitted at the bow of a power boat 2. The pushing force of the pushing bar 4 is adjusted by a jack 6. Since the floating body 1 receives the horizontal force of the pad plate 3 and the downward force of the pushing bar 4, the floating body 1 at the up-stream side is raised and applicable maximum stream speed can be increased.
