(B) is a front view and a side view showing a state where the seismic isolation device is lifted by the installation device of the same heavy object, and FIGS. 3 (a) and 3 (b).
FIG. 4 is a front view and a side view showing a state where the seismic isolation device is installed after the seismic isolation device is lifted by the heavy installation device.

The heavy-weight installation apparatus 1 is provided with a frame 2 assembled as a three-dimensional frame by, for example, steel, a traveling wheel 3 provided on a leg of the frame 2, and a vertically movable frame 2. It has a basic configuration including the beam 4 provided, lifting / lowering means 5 for lifting / lowering the beam 4, and a hanger 6 provided on the beam 4.

As shown in FIG.
Pillars 7 provided at respective corners of the prism, reinforcing members 8 parallel to each other connecting lower ends of the pillars 7, and a quadrangular shape in plan view connecting upper ends of the pillars 7 are assembled. And a reinforcing member 9.

The traveling wheels 3 are provided with, for example, casters or chill rollers. In the example shown here, the frame 2 is configured to be movable by towing, but a so-called self-propelled type in which a driving device is mounted and the driving wheels are forcibly rotated by the driving device may be used.

The beam 4 is attached to the end of a piston rod 10a of a hydraulic cylinder 10 constituting the lifting / lowering means 5 so as to straddle a side bar 11, and is mounted so as to extend between the two side bars 11. Beam 4
Is one in the example shown here, but the number is not limited to this, and the number of the two or more can be changed as needed.

In the example shown here, a plurality of hydraulic cylinders 10 incorporated in each column 7 are used as the elevating means 5. Note that a hydraulic pump that operates the hydraulic cylinder 10
The hydraulic operating portion of the solenoid valve may be incorporated in the frame 2, but in order to reduce the size of the device, the hydraulic operating portion may be separately provided to operate the elevating means 5 from outside.

The hanging member 6 is made of a thin material such as a plenty trolley in order to secure a hanging allowance as long as possible. Further, the plenty trolley is movable along the length direction of the beam 4.

Next, the operation of the heavy-weight installation apparatus 1 having the above configuration will be described. FIG. 4 shows a procedure for installing the seismic isolation device 22 in which the laminated rubber 20 and the support jack 21 are integrated with each other at a predetermined position underground using the heavy installation device 1.

Reference numeral 23 in step 1 denotes a steel pipe pile. Steps 2 to 6 also have the steel pipe pile 23, but are not shown. A substantially central portion of the steel pipe pile 23 and a portion surrounded by the reinforcing bar 24 is a place where the seismic isolation device 22 is installed.

The seismic isolation device 22 has been transported in advance to the vicinity of the installation location. In order to install the seismic isolation device 22 at the installation location, first, the heavy-weight installation device 1 according to the present invention is moved directly above the seismic isolation device 22 (step 2). Then, the seismic isolation device 22 is locked by the hanging member 6 attached to the beam 4, and in this state, the lifting / lowering means 5 is driven to lift the seismic isolation device 22 (step 3). That is,
Each of the hydraulic cylinders 10 incorporated in the column 7 is extended to lift the seismic isolation device 22 together with the side bar 11 and the beam 4 attached to the piston rod 10a.

As described above, while the hydraulic cylinder 10 is extended and the seismic isolation device 22 is suspended, the traveling wheel 3 is used to move the seismic isolation device 22 together with the frame 2 to just above the installation location (step). 4).

Next, while finely adjusting the position of the frame 2 so that the seismic isolation device 22 is accurately located at the installation location,

After the seismic isolation device 22 is lowered to the installation location, the locking of the seismic isolation device 22 by the hanging device 6 is released, and the vehicle is moved to the vicinity of the next installation location of the seismic isolation device 22 using the traveling wheels 3. Let it. Then, a series of operations described above are repeated, and the seismic isolation device 22 is installed at the installation location.

In the case of the above-described heavy-weight installation apparatus, since the apparatus itself has a simple configuration, the frame 2 can be set in accordance with the size of the seismic isolation apparatus 22 to be installed. Since the entire frame 2 is moved while the frame 22 is suspended, workability in a narrow location is excellent.

Further, since the elevating means 5 is constituted by a plurality of hydraulic cylinders 10 incorporated in the column 7 of the frame 1, it is not necessary to secure a special space for installing the elevating means, and the The size of the device can be reduced. For this reason, workability in narrow places can be further improved.

The lifting means 5 using the hydraulic cylinder 10 described above has a small dead space when suspending and supporting the seismic isolation device 22, so that a long allowance for suspension can be obtained. 20 and the support jack 21 can be suspended and installed while being integrally assembled. As a result, the installation time of the seismic isolation device 22 can be reduced, which greatly contributes to shortening the construction period.

The above-described embodiment is merely an example of the present invention, and the design can be changed as needed without departing from the scope of the invention. For example, in the above-described embodiment, the present invention is described by taking the case where the seismic isolation device 22 is installed as an example. However, the present invention is not limited to this. Needless to say, it can also be used when installing the device.
