PREFABRICATED FLOOR BOARD FOR BRIDGE AND FLOOR BOARD EXECUTION METHOD

PROBLEM TO BE SOLVED: To provide a prefabricated floor board for a bridge and a floor board execution method capable of assembling the whole required reinforcing bar assembly in a form in advance, capable of connecting prefabricated floor boards together by utilizing the reinforcing bars in the reinforcing bar assembly as they are, and capable of increasing strength. SOLUTION: Distributing bars 35 formed into a slender hoop shape are assembled to main reinforcements 31 in advance with at least one-end sections 35r protruded from the end of a form 21 to form a reinforcing bar assembly 23. The reinforcing bar assembly 23 is assembled in a steel form 21 to manufacture prefabricated floor boards 1A, 1B. The prefabricated floor boards 1A, 1B are arranged on a main girder 9, the end sections 35r, 35f of the distributing bars 35 of adjacent prefabricated floor boards 1A, 1B are inserted together, and multiple connecting bars 45 are inserted into loops 43 formed by the insertion. The distributing bars 35 can be assembled to the prefabricated floor boards 1A, 1B in advance, and strength is increased.
