METHOD OF MANUFACTURING BRIDGE PART TRACK

摘要

PROBLEM TO BE SOLVED: To provide a method of constructing a bridge part track, which easily constructs a track with high vibrationproof performance in a bridge part. SOLUTION: This method of manufacturing a bridge part track comprises: a releasing means stacking step of installing a steel plate 7 as a releasing means on the upper surface of each of the vertical beam and the lateral beam 2 of the bridge part 1; a formwork forming step of forming a formwork for preventing the main beam web 3 of the bridge part 1 to be integrated when concrete is placed and forming the concrete in a plate shape on the laid steel plates 7 stacked on the vertical beam and the lateral beam 2; a jackup step of jacking up a floor slab concrete 9; a vibrationproof material installation step of disposing a vibrationproof material 10 in the gaps between the jacked up floor slab concrete 9 and the vertical beam and the lateral beam 2; and a jack-down step of jacking down the floor slab concrete 9. The vibrationproof material is easily installed between the vertical beam and the lateral beam of the bridge part and the floor slab concrete. COPYRIGHT: (C)2009,JPO&INPIT
