Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vibration-proof mounting device for vibration-proofly supporting a vibrating device using existing anchor bolts protruding from a floor surface.

When supporting vibration-proof equipment using anchor bolts that conventionally fixed equipment to the floor, the third
As shown in the figure, the lower part of the mold angle 20 is fixed to the existing anchor bolt 1, and the elastic body 20 is attached to the upper part.
, place the mounting part 5a of the vibrating device 5 on it, and fix it with the bolt 22 and nuts 23, 24, or insert the elastic body 25 into the existing anchor bolt 1 as shown in FIG. , furthermore, the mounting part 5 of the vibration device 5
a through the hole 5b, and then insert another elastic body 26 from above.
The former uses a different type of angle, which increases the height of the equipment and may impede operation.Also, the height of the existing anchor bolt from the floor The length is set in advance to match the mounting part of the device, so even if you try to do the latter, the actual situation is that there is not enough length to insert the elastic bodies 25 and 26. Furthermore, the hole 5b of the vibrating device 5 is If it comes into contact with the anchor bolt 1, the vibration isolation effect is impaired, so it is necessary to enlarge the hole 5b with a drill or the like and insert the elastic body 28 into the gap to insulate the vibration, which is extremely time-consuming.

The present invention eliminates the drawbacks of the conventional method by making it possible to extremely easily mount a vibration device in a vibration-isolated manner without requiring any additional work by using existing anchor bolts.

Next, an embodiment of the vibration isolator used in the present invention shown in the attached FIG. 1 will be described in detail. A center hole 12a through which the anchor bolt 11 protruding from the floor is inserted is formed in the center of the bottomed cylindrical base 12, and an annular elastic body 14 is placed on the bottom surface 12b of the base 12 concentrically with the center hole 12a. Place it. Reference numeral 15 denotes a mounting bracket having a bolt 15a protruding from its upper part that can be inserted into the hole 10b of the mounting part 10a of the vibrating device 10, and a collar 15 provided at its lower part.
b is formed. This mounting bracket 15 is placed concentrically on the annular elastic body 14, and the annular elastic body 16 is placed on the collar 15b, and the upper collar 12c of the base 1 is placed.
A cover plate 17 is placed on the plate and fixed with bolts 18 and nuts 19, and at the same time, the elastic body 16 is pressed and fixed together to form a vibration isolator.

The nut 19 of this vibration isolator is removed, the cover plate 17 is removed, and the base 12 is separated. The anchor bolt 11 protruding from the floor is inserted into the center hole 12a of the separated base 12, and the base 12 is fixed to the floor with a nut 13. An annular elastic body 14 is placed around the nut 13 on the base 12, a mounting bracket 15 is placed on it, an annular elastic body 16 is placed on the collar 15b, and a cover plate 17 is placed on the annular elastic body 14. The upper flange 12 of the base 12
c and fix it with bolts 18 and nuts 19, and at the same time press and fix the elastic body 16, and then insert the mounting bolt 1 into the hole 10b of the mounting part 10a of the vibrating device 10.
5a and tighten and secure with a nut.

According to the present invention, the vibrations generated by the vibrating equipment are reliably absorbed by the elastic body in any direction, up, down, left, or right, and since the mounting bracket is on the same axis as the anchor bolt, the vibrating equipment can be stably supported. Since the height of the vibrating device is only increased by the thickness of the elastic body, there is no problem with operation, and even if the vibrating device tries to move on the floor due to vibration, it can be blocked by the anchor bolt.
