JOINT STRUCTURE OF SYNTHETIC FLOOR SLAB

摘要

PROBLEM TO BE SOLVED: To provide a joint structure of a synthetic floor slab restraining an opening width of a joint part and having sufficient fatigue durability even to a repeated load at automobile traveling time in tension bolt joining requiring no work scaffold and advantageous in terms of a construction period and economic efficiency. SOLUTION: End plates 2 having a bolt hole are installed in the shape of projecting above bottom steel plates 1 in the direction parallel to shape steel 4 in an end part of the bottom steel plates 1 of this synthetic floor slab, the mutual end plates 2 of the adjacent bottom steel plates 1 are fastened by bolts 3, and are joined in a tension bolt form. The plate thickness of the end plates 2 is set not less than 80% of a nominal diameter of the bolts 3. The ratio a2/a1 of a distance a2 up to the upper end of the end plates 2 from the center of the bolt hole to a distance a1 up to an upper surface of the bottom steel plates 1 from the center of the bolt hole is set not less than 0.5.
