Abstract: The present invention relates to a technique wherein a sliding member is disposed between a supporting portion formed on a head of a pile and a binding portion formed on a bottom of a footing. Thus, the binding portion of the head of the pile acts as a roller bearing structure or a pin structure, thereby making it possible to relatively slidingly move in a horizontal direction or slidingly rotate the footing and the pile. As a result, the present invention can prevent damage or destruction in applying a great external force such as an earthquake to the structure, enhance execution and achieve low-cost by means of decreasing the amount of reinforcing steel used.
