2. Description of the Related Art In recent years, various seismic isolation structures have been adopted in newly constructed office buildings and condominiums as measures against large earthquakes. Such a seismic isolation structure is a structure that absorbs vibration by making the building itself a flexible structure, or that a building has a float structure by installing an elastic body such as laminated rubber between the foundation of the building and the main body of the building. Various methods have been proposed.

[0003] On the other hand, such a seismic isolation structure is intended for a new building and cannot be used for an existing building. However, it is also an important issue as a countermeasure against earthquake disaster to make a large number of existing buildings seismically isolated structures resistant to earthquakes. Therefore, a method in which a base is formed by digging below the existing building, and a seismic isolation device is installed between the base and the building foundation has also been proposed as an anti-seismic measure for the existing building.

However, in such a method of installing a seismic isolation device on an existing building, since the building-side reinforcing beam is located above the place where the seismic isolation device is to be installed, the seismic isolation device is lifted. There is a problem that it cannot be installed at a predetermined place and its movement is difficult. in this case,
Since the seismic isolation device itself has a weight of 600 to 700 kg, it is difficult to move or install it manually. Therefore, it was extremely difficult to manually move and install the seismic isolation device while positioning it under the building. Therefore, there has been a demand for a jig capable of easily and accurately installing a seismic isolation device under a building.

An object of the present invention is to provide a jig for installing a seismic isolation device which can easily and accurately install the seismic isolation device at a predetermined position.

The above and other objects and novel features of the present invention will become apparent from the description of the present specification and the accompanying drawings.

By matching the color and position of the marking on the gantry 3 (painted in yellow) and the gauge plate 18, the gantry 3 can always be installed at an accurate position. And the gantry 3
Since the template 13 is also provided with a positioning hole 13a, if the seismic isolation device 31 is placed in accordance with the template 13, the seismic isolation device 31 is moved to the correct position while always maintaining an accurate positional relationship. It can be installed.

Next, a procedure for installing the seismic isolation device 31 under a building using the installation jig 1 according to the present invention will be described. 8 to 13 are explanatory diagrams showing the procedure. In FIGS. 8 to 13, the configurations of the trolley 2 and the gantry 3 are simplified for explanation. 9 and the subsequent drawings, the building 50 and the support 4 are omitted.

In the installation jig 1, the gauge plate 18 is first attached to the grout 54 under the building 50.
That is, the gauge hole 18a of the gauge plate 18 and the mounting hole 56
Then, the gauge plate 18 is bolted on the lower base plate 53 by aligning the bolts with the bolt holes 55. After installing the gauge plate 18 in this manner, the marking 28 of the gauge plate 18 and the marking 29a of the gantry 3 and the gauge plate 18

8 are buried, and the base 52 is formed by the primary and secondary casting. The lower base plate 53 is placed on the base 52 completed in this way after adjusting the level with an adjustment bolt. Then, the non-shrinkable mortar is filled between the lower base plate 53 and the base 52 adjusted in the horizontal state through the grout injection hole 59 to form the grout portion 54.

On the other hand, after setting the gantry 3, FIG.
As shown in (1), the seismic isolation device 31 is temporarily placed on the template 13 outside the building. At this time, the mounting hole 33a of the seismic isolation device 31 and the positioning hole 13a of the template 13
And the seismic isolation device 31 is mounted. As a result, the seismic isolation device 31 is temporarily placed on the gantry 3 in an accurate direction. The seismic isolation device 31 is lifted by a wire or the like and carried to the position of the template 13.

Next, as shown in FIG. 10, the cart 2 is placed on the gantry 3 from the outside of the building, and the elastic body 34 of the seismic isolation device 31 is inserted into the recess 22a of the cart 2 to mount the seismic isolation device 31.

After attaching the cart 2 to the seismic isolation device 31, FIG.
As shown in FIG. 1, the screw support 23 is raised to lift the seismic isolation device 31 (up position), and in this state, the carriage 2 is moved under the building. Under the building, the trolley 2 is stopped on the lower base plate 53 which is the installation position of the seismic isolation device, and the mounting hole 33a of the seismic isolation device 31 and the mounting hole 56 of the lower base plate 53 are aligned (FIG. 12). The mounting hole 56 communicates with the bolt hole 55 of the grout portion 54. In this case, the gantry 3 is installed in alignment with the bolt hole 55 by the gauge plate 18, and the seismic isolation device 31 is also mounted on the trolley 2 together with the bolt hole 55 by the template 13. Hole 5
Positioning with 5 is easy.

After aligning the mounting holes 33a, the screw support 23 is lowered and the seismic isolation device 31 is lowered onto the lower base plate 53 (FIG. 13). And mounting hole 3
3a, the bolt 57 is screwed into the bolt hole 55 via the mounting hole 56, and the seismic isolation device 31 is fixed on the base 52, whereby the installation work of the seismic isolation device 31 is completed.

The installation jig 1 is withdrawn after the seismic isolation device 31 is installed. That is, the carriage 2 is first returned to the template 13 side and lowered from the gantry 3, and the support 4 is removed to make the gantry 3 free. Thereafter, the bolt 19 is removed, the steel material 11d is removed, and the gantry 3 is pulled out from under the building to complete the withdrawal of the installation jig 1 set.

As described above, according to the installation jig 1 of the present invention, the seismic isolation device 31 can be easily and accurately installed at a predetermined position only by performing positioning on the template 13. Further, since the seismic isolation device 31 is moved by the carriage 2, it is possible to move and install the seismic isolation device 31 without applying excessive force.

Although the invention made by the inventor has been specifically described based on the embodiment, the invention is not limited to the embodiment and can be variously modified without departing from the gist of the invention. Needless to say,

For example, in the above-described embodiment, the configuration using one gauge plate 18 as the gauge means has been described.
Such means is not limited to the gauge plate 18. That is, as long as the gantry 3 can be installed at a predetermined position, the gantry 3 may be a strip having a gauge hole that matches the bolt hole, and the material may be not only iron but also paper or synthetic resin. In this case, a band plate or a synthetic resin material is lighter in weight and easier to handle than a single plate material.

Further, by associating the position of the stopper 16 with the position of the gauge plate 18, the position where the carriage 2 stops by the stopper 16 can be exactly the installation position of the seismic isolation device 31. .

Further, the gauge plate 18 can be temporarily fixed to the gantry 3 for use. That is, the gantry 3
A hole or a notch for positioning may be provided in each of the gauge plate 18 and the gauge plate 18, and a positioning member such as a pin may be fitted into the hole or notch, and the support 4 may be stretched and fixed with the base 3 temporarily fixed. In addition, the color, shape, and installation position of the marking 28 and the like are arbitrary. For example, a line may be provided at the position where the end of the gauge plate 18 comes, or a mark member or a bolt may be attached.

In the above description, the case where the invention made by the present inventor is mainly applied to the installation of a seismic isolation device in an existing building, which is a field of use, has been described. However, the present invention is not limited to this. It can also be applied to the installation of seismic isolation devices on new buildings.
