Embodiment 1

[0055] Such as figure 1 and 2 As shown, the seismic isolation structure 11 of Embodiment 1 is installed between the machine 1 as a heavy object and the ground F. As shown in FIG. The machine 1 includes a plurality of legs 2 , while the isolation structure 11 includes a mechanism for adjusting the height of the legs 2 relative to the ground F. As shown in FIG. The shock-isolation structure 11 is provided with: a shock-absorbing pad 12 (referring to figure 2 ), the vibration damping pad is set on the ground F; the pressure plate 13, the pressure plate 13 squeezes the vibration damping pad 12; plate 13.

[0056] Such as figure 2 and 3 As shown, the vibration-damping pad 12 is composed of a gel-like elastic body 15 having elastic-viscosity and a support body 16 capable of plastic deformation. The gel-like elastic body 15 is formed in a circular shape from a transparent or translucent polymer material. Adhesive layers 15a and 15b (see image 3 a) Provided on the bottom and...

Embodiment 2

[0064] exist Figure 5 and 6 In the shown shock-absorbing structure 211 , the base 21 of the holder 14 is clamped to the pressure plate 13 by the four arcuate members 28 with the vibration-proof rubber 29 interposed between the base 21 and the pressure plate 13 . The arcuate parts 28 are assembled to cross each other, and are fastened with bolts 30 to bolts 31 provided on the pressing plate 13 . Bonded to the lower surface of the base 21 is an intermediate plate 32 provided with a restricting wall 34 formed along the periphery of the intermediate plate 32 for blocking the caulking compound 33 . In addition, the anti-vibration rubber 29 is disposed within the restricting wall 34, so that the upper and lower two-layer elastic members composed of the anti-vibration rubber 29 and the vibration-damping pad 12 can provide improved shock absorption.

Embodiment 3

[0066] according to Figure 7 and 8 In the shown shock-absorbing structure 311 , the holder 14 includes: a cylindrical member 36 surrounding the leg 6 of the weight 5 , and the lateral movement of the leg 6 on the pressing plate 13 is restricted by the cylindrical member 36 . The legs 6 are attached to the weight 5 (only part of which is shown) in a manner that allows the height of the legs 6 to be adjusted with screws 7 , and the legs 6 are also removably inserted into the cylindrical member 36 . Therefore, the shock-absorbing structure 311 of Embodiment 3 is preferably applicable to heavy objects that are relatively light in weight and need to be transported, such as tool tables and display cabinets. Note that, in the illustrated vibration-damping pad 12 , a single support body 16 and a single ring 12 are embedded at the center of the gel-like elastic body 15 .

Abstract

[Problem] To prevent, using a simple seismic isolation structure, vibration, noise, and overturning of a heavy object arranged on a floor surface where an anchor bolt cannot be used. [Solution] A seismic isolation structure (11) for a machine (1), wherein a plastically deformable support body (16) is buried in a gel-like elastic body (15) in a vibration-damping pad (12). A rear-surface adhesive layer in the gel-like elastic body (15) is bonded to the floor surface, and a pressurizing plate (13) is bonded to a surface adhesive layer of the gel-like elastic body (15). The pressurizing plate (13) receives the weight of the machine (1) and applies pressure uniformly to the entire vibration-damping pad (12). The base (21) of a holder (14) is welded to the upper surface of the pressurizing plate (13); a bolt (22) vertically installed on the base (21) is caused to penetrate a through-hole (3) in a leg section (2); and the leg section (2) is confined upon the pressurizing plate (13), by the holder (14), so as to be horizontally immovable.

Description

technical field [0001] The present invention relates to an isolation structure and an isolation method for preventing vibration, noise, and toppling due to an earthquake of various heavy objects installed on the ground, such as machinery, water tanks, showcases, and the like. Background technique [0002] Traditionally, anchor bolts are used to fix facilities installed in factories to the ground. For example, Figure 12 The machine 51 shown in FIG. However, there are various types of heavy objects that cannot use the anchor bolt 53 as a means for preventing it from toppling over. For example, if Figure 13 As shown, a water tank 55 for storing drinking water is held in an elevated position on a base frame 56 due to hygienic requirements. The legs 57 of the pedestal 56 are supported on a waterproof floor F via a metal floor 58 to facilitate rearrangement when the manufacturing line is changed. [0003] In addition, for the convenience of installation, a shock-isolating st...
