Problems solved by technology

[0005] In addition, in the construction method of the building using the existing shock absorber, it is necessary to sandwich the air jack between the upper and lower foundations, and to lift the upper foundation after the concrete has hardened. increase cost
Furthermore, since the sliding support main body is inserted under the concrete base, it cannot penetrate deep inside, so it is restricted, and the sliding support main body can only be arranged at the peripheral part of the hand reach range.

Embodiment Construction

[0064] The damping device 1 of the first embodiment of the present invention is as Figure 1~3 As shown, for example, a low-friction combined structure is formed by the point contact of an approximately flat hardboard base 3 with a smooth flat sliding plate 4 having Surface layer of convex surface protrusion 2. The convex curved surface protrusions 2 are formed at least three or more. image 3 In the shown embodiment, for example, the pitch t=50mm is arranged in a row, and the hard board base 3 can obtain a more stable sliding by aligning the pitch t in the range of 10mm≤t≤100mm. performance. The height of the shock absorber 1 is about 4mm in this embodiment.

[0065] Such as figure 2 As shown, the shock absorber 1 has a substantially planar hard plate base 3 having a convexly curved surface protrusion 2 as a lower base, and a smooth flat slide plate 4 is disposed thereon. The sliding plate 4 is formed as a movable body having a tapered shape 4c formed by upward bending ...

Abstract

The present invention provides a seismic isolation apparatus which, as well as widening an applicable shaking range, can be easily configured and is low in height, a seismic isolation apparatus is configured of a low friction combination formed by a point contact between a planar hard plate base, which has a surface on which are disposed at least three convexly curved projections of a uniform height, and a glide plate which is a smooth, hard, flat plate.

Description

technical field [0001] The present invention relates to a shock absorber, equipment such as an automatic vending machine using the shock absorber, and structures such as buildings. Background technique [0002] The ideal shock absorption in the shock absorber is the case where the coefficient of friction is zero. In this case, even if the support surface vibrates due to an earthquake, the object does not move at all. If the coefficient of friction is not 0, even if there is only a small amount, objects will move, and residual displacement may occur after an earthquake. However, if this residual displacement can be easily returned, there is no problem as an earthquake countermeasure. However, if the coefficient of friction is too small, there is a problem that it is easy to move during normal use. Design to meet the coefficient of friction of these two aspects. Generally, in order to reduce the coefficient of friction, in addition to using materials such as bearings and t...
