PROBLEM TO BE SOLVED: To provide a structure of a floor slab connecting part superior in a vibration control characteristic with high expandability by having a floor slab expandable connecting device having a reinforced fiber sheet, and capable of reducing generation of vibration and noise caused by the passing of a vehicle by preventing swelling of a road surface, particularly, in summer. SOLUTION: This floor slab connecting part 100 is provided with the floor slab expandable connecting device 1 having support plates 10A and 10B respectively installed in a skeleton 201 positioned on both sides of a joint opening part G in a connecting part of a floor slab 101, and the reinforced fiber sheet 3 having an expandable curved part 3A, and having at least a part joined to both support plates 10A and 10B. The support plates 10A and 10B have an installing part 11 installed in the skeleton 201 positioned on both sides of the joint opening part G, and a tip part area 12 continuously connected to the installing part 11, and extending to the reinforced fiber sheet curved part 3A. The tip part area 12 is formed into the deformable free end. COPYRIGHT: (C)2005,JPO&NCIPI |
