摘要： The seismic isolation sliding support bearing system includes a pair of sliding bearings, which can be moved relatively to each other and are arranged in opposition and in contact with each other between a superstructure and a substructure. At least one of the pair of sliding bearings is a sliding bearing (a) made from a molding, having a porous structure including a plurality of voids, of a composition including PTFE as a main component and aromatic polyester resin, or a composite including a base member having the molding on the surface thereof. Furthermore, a lubricant holding layer for holding a flow lubricant in the voids is formed in a surface portion of the molding. Since the sliding bearing (a) has a high compression elastic modulus (of 900 MPa or more) and a low coefficient of friction (of 0.02 or less) and can maintain the low friction for a long period of time, it can be particularly effectively used in a seismic isolation sliding bearing support system for structures with a large load.

摘要： 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.

摘要： The present invention relates to a technique wherein a complex structure is adopted as a joint structure between each head of plural piles (1) and a bottom of a footing (2), and the complex structure may be selected among either a complex of a roller bearing structure (Y) interposing a sliding member (12) and a pin bearing structure (X) interposing a sliding member (32), another complex of a rigid joint structure (Z) and the roller bearing structure (Y), or still another complex of the rigid joint structure (Z) and a pin bearing structure (X). This can restrain the rotation of an upper structure (A), reduce stress concentration applied to a joint portion and occurrence of a bending moment on the pile (1) in applying a great external force such as an earthquake thereto, prevent damages or destroys of the joint portion and the pile, and also enhance excellent positional restoration performance for restoring the upper structure (A) to an initial position thereof, after the earthquake happens.
