Definitions
- the present invention relates to a joining member used for a laminated rubber body used in a seismic isolation structure in a building structure, and a laminated rubber body and a structure using the joining member.
- Bearing mounting structure for building structures and civil engineering structures especially laminated rubber bodies used for seismic isolation structures in building structures, laminated rubber bodies used for seismic isolation structures and horizontal force distribution structures in civil engineering structures Due to the structure of the rubber body, it has a large yield strength in the compression direction and can support the load of the upper structure, but the yield strength in the tensile direction is inferior to that in the compression direction.
- the flange plates 66 and 67 of the laminated rubber body 64 are fixed to the anchor plate 65 fixed to the lower structure 69 such as the foundation of the structure 61 and the upper structure 70.
- the mounting bolt 62 and the cap nut 63 are fixed to the upper plate 68, and a large horizontal deformation acts on the laminated rubber body 64, the relative relationship between the upper surface 64a and the lower surface 64b of the laminated rubber body 64 in the horizontal direction. Due to the deviation, a rotational moment is generated in the laminated rubber body 64, and a vertical pulling force is generated in the mounting structure portion of the laminated rubber body 64.
- the dowel pin type joining method at the time of large horizontal deformation, the dowel pin part is separated, and the tensile force in the vertical direction does not act on the bearing mounting structure part. However, if the degree of separation is further increased, the dowel pin is detached and laminated. There was a risk of deformation in the rubber body itself. In such a state, the horizontal resistance force of the laminated rubber body is reduced, and there is a risk that the laminated rubber body starts to fall. Therefore, when the mounting structure using the dowel pins is adopted, the horizontal force is reduced. It was necessary to determine the use limit of the laminated rubber body with the amount of deformation as the fall limit (rollout displacement) (see Non-Patent Document 1, for example).
- the laminated rubber body and the upper and lower structures are Various studies have been conducted on the binding method.
- the laminated rubber body is connected to the upper structure or the lower structure with bolts, if a large horizontal deformation occurs in the laminated rubber body, the vertical tensile force due to the rotational moment is exerted on the laminated rubber body. May cause damage to or damage to the laminated rubber body, damage to the structure due to excessive input to the superstructure or substructure, and, in addition, in a building structure with a large aspect ratio, There is a possibility that an excessive tensile force due to rocking acts on the laminated rubber body.
- Patent Document 1 discloses that one mounting plate (flange plate) fixed to one end surface of the laminated rubber seismic isolation device and an outer edge of one end surface of the laminated rubber seismic isolation device. It is fixed to one mounting plate and to the mounting surface of the foundation or structure facing one end surface of the laminated rubber seismic isolation device inside the portion fixed to the one mounting plate. Since the other mounting plate is provided, when the lift occurs between the upper structure and the lower structure, the mutual fixing portion of both mounting plates can move upward, and the mounting plate can be bent. Since rigidity can be utilized, a technique is disclosed in which a large vertical tensile force does not act on the laminated rubber seismic isolation bearing device.
- Patent Document 2 a thin-walled portion or an opening for reducing the bending rigidity of the flange member is formed in a portion between the outer periphery of the laminated rubber portion and the fixing portion to the structural member, and the laminated rubber body A technique for preventing the laminated rubber body from being damaged even when a pulling force is applied is disclosed.
- Patent Document 3 discloses a configuration in which the bolt is fastened to the isolator and the structure via a buffer seat, for example, a disc spring, and is firmly tightened for horizontal movement, and the buffer seat is used for vertical movement. A technique for making a soft fastening is shown.
- a buffer seat for example, a disc spring
- Patent Document 4 discloses a mechanism for pulling out a seismic isolation device in which a cushion material such as a rubber sheet is interposed between a flange portion of a laminated rubber and a head portion of a bolt that tightly connects the casing. As shown, a structure consisting of a ring-shaped steel plate and rubber sheet is shown, and the cushion material can be deformed in the thickness direction, so even if an instantaneous lifting force is applied during an earthquake, etc., deformation or destruction of the cushion material A technique for releasing the force and applying no tensile force to the laminated rubber is shown.
- a cushion material such as a rubber sheet
- Patent Document 5 discloses a vertical motion seismic isolation body in which a laminated rubber body is arranged so that the shear direction of the laminated rubber body acts in the vertical direction against vertical vibration. Although it is different from the problem, the mounting bolt of the horizontal motion isolation body that shears in the horizontal direction and the laminated rubber body that constitutes the horizontal motion isolation body even if the upper structure is lifted up in the secondary direction Thus, a vertical tensile force does not act on the laminated rubber portion.
- a laminated rubber body mounting plate is made to have a double structure as in Patent Document 1, or a flange is processed to reduce the bending rigidity of the flange member of the laminated rubber body as in Patent Document 2, so that the laminated rubber is processed.
- the means for reducing the tensile force on the body involved a design change of the structure body of the laminated rubber body, which required cost and time and required a review of the installation space, and was not easily applicable.
- the technique of interposing a cushioning material in the attachment portion of the laminated rubber body can reduce the tensile force applied to the laminated rubber due to lifting, and further increases the size of the laminated rubber body. It can be said that it is preferable because it can cope with the relaxation of the pulling force caused by horizontal deformation.
- rust prevention of the contact portion of the steel material or a portion that causes elastic deformation becomes a problem.
