摘要： PROBLEM TO BE SOLVED: To provide installation structure of a bridge bearing device and an installation method capable of easily carrying out work for installing an elastic bearing body to a lower structure, at the same time, acting on an anchor bolt while buffering lateral, abrupt and large impact force and shear force caused by horizontal movement by means of a cylindrical member or a cylindrical impact absorption member and preventing the anchor bolt from large impact force abruptly acting thereon. SOLUTION: This structure is so constituted that an anchor bolt 9 is inserted into an anchor bolt insertion hole 13 of a base plate 5 in an elastic bearing device and that a bridge elastic bearing device is fixed to a lower structure 2 with the anchor bolt 9. In that case, the inside diameter of an anchor bolt insertion hole 1 in the base plate 5 is so formed that it is larger than an outside diameter of a vertical intermediate section of the anchor bolt 9 inserted from an upper side of the anchor bolt insertion hole 13 and embedded in the lower structure 2 to fix, the cylindrical impact absorption member attached anchor bolt 9 fitting and interlocking a cylindrical impact absorption member 10 is inserted into the anchor bolt insertion hole 1 of the base plate 5 and, at the same time, the circumferential surface of the cylindrical impact absorption member 10 is so placed that it approaches the inside circumferential surface of the anchor bolt insertion hole 1 to oppose them.

摘要： PURPOSE:To provide a wide plastic region in the stress-strain characteristic as well as to enlarge the limit and coefficient of elasticity in a rubber cushion by arranging pipes inside a rubber board for providing a required stress-strain characteristic and strength. CONSTITUTION:A plurality of steel pipes 2 are buried in a rubber board 1 to be almost in parallel with each other and the obverse and reverse faces of the rubber board 1. An abverse plate 3 and a reverse plate 4 made of steel are arranged on both faces of the rubber board 1. Besides, side plates 5A of thin steel with an arc- shaped section are arranged on parallel sides with pipes 2 for restraining the lateral expansion of the rubber. In this construction, the limit and coefficient of elasticity in a rubber cushion can be enlarged greatly by a simple process. Since pipes 2 cause plastic deformation against an excess load, a very wide plastic region can be provided in the stress- strain characteristic of the rubber cushion.

摘要： PROBLEM TO BE SOLVED: To provide a construction method which can repair an existing bridge support device without jacking up an upper structure. SOLUTION: This repair construction method for an existing bridge support device supports a supperstructure through a steel support on a substructure 2. A horizontal force support function is lost by removing a projection of a steel support and turned into a support exclusive for a vertical force, and as a newly provided horizontal force support, a reaction wall 6 is constructed in the substructure 2 with a fixed clearance 7 provided onto the side of a steel box frame 4 being the superstructure, and the clearance 7 formed between the side of the reaction wall 6 and the steel box frame 4 is longitudinally provided with a damping member 8 having attaching plates 13, 14 arranged on both the sides of an elastic body 12, and either attaching plate 13 is fixed to the side of the reaction wall 6 and the other attaching plate 14 is fixed to the steel box frame 4.

摘要： PROBLEM TO BE SOLVED: To obtain a quake-free rubber composition having high attenuating properties, by making the composition include an unvulcanized rubber, a telomer and a vulcanizing agent. SOLUTION: This composition includes (A) an unvulcanized rubber (a natural rubber, an SBR, an NBR, a BR or the like), (B) a telomer having 2,000-8,000 number-average molecular weight (e.g. one synthesized by using trichloro acetic acid, carbon tetrachloride or the like as a telogen and acrylic acid hexyl ester or the like as a taxogen and (C) a vulcanizing agent. In the composition, 1-15 pts.wt. of the component B is mixed with 100 pts.wt. of the component A. In vulcanization using the components, carbon black is added to the components to improve the properties of a vulcanized rubber.
