<p>A sliding member (22) is interposed between a bearing portion (13) formed on the head of a pile (12) and a connection (19) formed on a lower portion of a footing (18) to form a pile head connection in a roller support structure or pin structure, whereby the footing (18) and the pile (12) are made horizontally slidable or slidingly rotatable relative to each other to prevent damage and breakage at the time of application of great external forces such as in earthquakes, thereby reducing an amount of reinforcement used for such components to improve workability and cost reduction. </p> |
