Description

  The present invention relates to a cartridge type support device for supporting various structures such as buildings and bridges, and a receptor structure for a support device for detachably holding the cartridge type support device.

  2. Description of the Related Art Conventionally, it is common that a support device that performs a seismic isolation function is disposed between an upper structure and a lower structure constituting a structure such as a building or a bridge. The bearing device is required to have a vertical load support function for supporting a vertical load, a horizontal load support function for supporting a horizontal load, and a rotation support function for following rotation in a vertical plane of a structure or supporting a rotational load. . As a configuration form for achieving these functions, the bearing device is roughly classified into a steel bearing device in which most of the components are made of metal, and a rubber bearing device whose main component is rubber. In particular, after the Great Hanshin-Awaji Earthquake in 1995, many rubber bearing devices have been demanded instead of the steel bearing devices that have been the mainstream until then. This is because in the case of bridges that used steel bearing devices, not only the bridge girder, which is the upper structure, but also the lower structures such as the bridge piers collapsed across the board, resulting in a devastating situation. This is due to the experience of avoiding collapse at the place where the device was installed.

  By the way, in the steel bearing device, for example, a roller type as described in Patent Document 1, a pivot type as described in Patent Document 2, or a pin bearing as described in Patent Document 3 is used. There are many forms such as molds, and each is devised to support various input loads. However, common problems with these steel bearings are that there may be a decrease in strength due to rust, wear, etc., and a decrease or deterioration in seismic isolation performance, and that a decrease in performance is also observed due to dust and the like due to wind and snow over time. Can be mentioned. In addition, the seismic isolation performance is inferior to that of rubber bearings due to the previous earthquake, and socially, it is required to replace steel bearings with rubber bearings in existing bridges.

  On the other hand, the rubber bearing device is described in, for example, a laminated rubber bearing device as described in Patent Document 4 or a patent document 5 in which this laminated rubber bearing device is further downsized to improve the load resistance of a vertical load. A bearing device or the like configured in such a cylindrical shape has been proposed. However, it is a rubber bearing device that has been widely used in place of steel bearings. However, in the Chuetsu earthquake that occurred in 2004, in the bridge where the laminated rubber bearing device was introduced, the upper structure and lower structure Although damage was avoided, there were some cases where the bearing device itself was damaged.

  In view of the large scale and long period of earthquakes expected in recent years, it is desirable to adopt a rubber bearing device that can protect the upper structure and lower structure from damage from the viewpoint of safety and economic rationality. It is also considered necessary to replace the existing steel bearing device with a rubber bearing device. Moreover, even if it is a rubber bearing device, replacing it with a new rubber bearing device promptly after the earthquake will extend the life of the entire structure, which is social infrastructure, or reduce the life cycle cost. Is important not only from the viewpoint of social safety.

  Also in such a background, conventionally, whether the support device is a steel support device or a rubber support device, the installation and installation to the structure is performed by almost the same method. That is, in the support device, a base plate that is the lowermost base is fixed to the lower structure with an anchor bolt or the like, and a sole plate that is the uppermost base is fixed to the upper structure with a set bolt or the like. At this time, a shear key is generally interposed between the upper structure and the support device so that a resistance force against an input of a horizontal load can be obtained.

JP 2002-285514 A JP-A-4-47010 JP 2004-84263 A JP 2002-181129 A JP 2005-337002 A

  In the mounting operation of the support device between the upper structure and the lower structure in such a structure, at least the support device and the upper structure are embedded while the support device in which anchor bolts are set in advance is embedded in the lower structure. It is necessary to jack up the upper structure by the height of the shear key inserted between the two. Therefore, since the upper structure is lifted by that amount, for example, a considerable amount of height difference occurs in the joint portion of the bridge girder. For this reason, in exchanging the bearing device in the existing bridge, traffic regulation such as closing of the road is necessary, and there is a problem that the construction cost is increased in addition to the social influence.

  Of course, the replacement work of the support device requires not only jack-up, but also complicated work such as attaching / detaching the set bolt, detaching from the anchor bolt, and mounting, etc., so it is not easy and expensive. is there.

  In general, since the size of the support device is set by the size of the upper structure such as a bridge, a support device for a small upper structure cannot be replaced and installed as a support device for a large upper structure. And vice versa. For this reason, it is necessary to design and manufacture a dedicated support device in accordance with specifications such as the size of the upper structure, leading to an increase in product cost.

  The present invention has been made in view of the above-described circumstances, and the construction at the initial installation is easy, and the replacement work after the next time can be remarkably facilitated and the cost can be reduced.
