Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding laminated rubber bearing for supporting various structures such as buildings and test facilities so as to be capable of horizontal seismic isolation or vibration isolation, and a method of assembling the bearing.

[0002]

2. Description of the Related Art A laminated rubber bearing is used as a bearing for supporting various structures such as buildings and test facilities so as to be seismically isolated or isolated. In buildings built on foundations and precision equipment installed on installation stands, it is necessary to minimize the transmission of external vibrations caused by earthquakes and passing vehicles, and to attenuate the transmitted vibrations as early as possible. Required. Also,
To protect the structure from earthquakes,
When protecting structures requiring high security and precision, such as computers, semiconductor manufacturing equipment, and electron microscopes, from vibrations, in addition to shutting off large-scale earthquakes over a wide range of frequencies, shut down even minute vibrations. Is also requested.

[0003] In order to respond to such demands and to elastically support various structures so as to be seismically isolated or anti-vibration, laminated rubber bearings are used. This laminated rubber bearing for seismic isolation support has a laminated rubber portion in which a rubber layer and a reinforcing plate are alternately laminated and integrated. As the reinforcing plate, for example, a metal or hard plastic plate is used. Such a laminated rubber bearing body is usually manufactured by a method in which a rubber material and a reinforcing plate, which are alternately laminated, and a mounting flange are integrated into a mold by vulcanization molding.
The laminated rubber bearing body has a high spring constant in the vertical direction and a low spring constant in the horizontal direction, and the vertical / horizontal spring constant ratio may be as large as 800 or more.

Further, in the above-described laminated rubber bearing, holes (cavities) are formed through the rubber layer and the reinforcing plate in the vertical direction in order to improve the vibration damping ability, and raw rubber and tar are formed therein. By encapsulating a filler of viscoelastic material such as metallic lead (column-shaped lead plug), it is possible to prevent the free surface area of the bearing from increasing and restrain the deformation, thereby preventing the longitudinal spring constant from excessively decreasing. Laminated rubber bearings having increased vibration damping capacity have been proposed in, for example, JP-A-63-293340 and JP-A-2000-110878.

On the other hand, when various structures are supported by seismic isolation or vibration isolation, in addition to the bearings fixed to the upper and lower structural members,
It has been practiced to use a slide bearing (slidable in the horizontal direction) that can slide on one structural member.
Such a sliding bearing may be a laminated rubber bearing (sliding laminated rubber bearing) using a laminated rubber in which a rubber layer and a reinforcing plate are alternately laminated and integrated. Figure 1
5 is a schematic longitudinal sectional view showing an example of a conventional slide laminated rubber bearing, and FIG. 16 is a schematic plan view taken along line 16-16 in FIG.

In FIG. 15 and FIG.
And the reinforcing plate 112 are alternately laminated, a flange member 113 is joined to the lower surface thereof, and the end face fitting 1 is attached to the upper surface thereof.
The laminated rubber portion 115 is formed by joining the two components 14 and integrating them by vulcanization molding or the like. This laminated rubber part 1
A slide plate portion 116 is positioned and fixed to the end face metal fitting 114 forming the upper end face of the slide 15. In the illustrated example, the sliding plate portion 116 is configured by fixing a sheet-like sliding surface member 118 to the surface of a sliding plate (back plate) 117. The structural member supported by the seismic isolation is slidably supported on the surface (slip surface) of the slip surface member 118. And, the sliding plate portion 116 includes:
A key member (a column-shaped or disk-shaped key plate in the illustrated example) is attached to the end surface fitting 114 of the laminated rubber portion 115.
A shear force is applied at 119 and a plurality of locations (for example, eight locations) on the circumference are fastened and fixed by bolts 120.

The key member 119 is for positioning the sliding plate portion 116 in the horizontal direction, and the bolt 120 is for connecting the sliding plate portion 116 to the laminated rubber portion 115 in a retaining state. . By joining and fixing the slide plate portion 116 to the laminated rubber portion 115 in this manner, a slide laminated rubber support (a slide support made of laminated rubber) 110 is formed. When the sliding laminated rubber bearing body 110 is actually constructed and used, the flange member 113 is fastened to a lower structural member (for example, a foundation) with a bolt or the like, and the flange member 113 is mounted on the sliding plate portion 116 on the upper side. By mounting the structural member (for example, a building or a test device), the upper structural member is slidably supported so as to be slidable.

[0008]

However, in the conventional sliding laminated rubber bearing, as shown in FIGS. 15 and 16, a predetermined means is provided at the peripheral portion as a means for fixing the sliding plate 117 to the laminated rubber portion 115. Since the fastening means such as a plurality of bolts 120 provided at intervals are used, useless space for fixing means irrespective of the performance of the slide bearing is required, and the slip surface formed by the slip surface member 118 is required. Is reduced by the area of the arrangement area of the fastening (fixing) means in the peripheral portion, and the ratio of the area of the slip surface (effective area) to the installation area of the slide bearing is reduced. There were technical issues to be addressed. That is, the total area of the sliding plate portion 116 (or the total cross-sectional area of the laminated rubber portion 115) is equal to the sliding plate portion 116.
It has to be much larger than the area of the effective sliding surface 118 formed thereon, which has the disadvantage that it is difficult to convert the bearing structure into a corresponding portion.

The present invention has been made in view of such technical problems, and an object of the present invention is to significantly increase the ratio of the area of the slip surface to the cross-sectional area of the laminated rubber portion. It is an object of the present invention to provide a sliding laminated rubber bearing and a method for assembling the same, which can reduce the size and installation space of the laminated rubber bearing, as well as reduce workability and man-hours during construction.
