Fig. 2 a, Fig. 2 b, Fig. 2 c illustrate the example to exempting from the collocation method shaking the elastic body 19 that post 10 configures.Show 2 the limit 24x extended in (X-direction) in the width direction of exempting from the bearing surface 8,9 shaking post 10 with rectangular shape, separately 4 elastic bodys 19 are configured with phase mutual edge distance L1, and do not possess the situation of elastic body 19 at 2 the limit 24y extended along depth direction (Y direction).

As shown in Fig. 2 a, Fig. 2 b, Fig. 2 c, the elastic body 19 arranged at the limit 24x of width and the limit 24y of depth direction can be selected and arrange arbitrary quantity.Thus, as shown in Figure 1 b, stop component 13 can be connected to the periphery that level two direction of principal axis X, Y are at random set in abutment flange 17, exempt to shake the triggering loads that post 10 starts when tilting centered by fulcrum E.Described elastic body 19 can use the elastic body possessing identical resilience also to change and arrange several configuration, in addition, can also configure the different elastic body of resilience 19.

Fig. 6 a, Fig. 6 b, Fig. 6 c illustrate and exempt to shake the displacement limiting mechanism 25 that exempting from when post 10 tilts shakes post 10 and the displacement between two post parts 1A, 1B described in restriction.In addition, in this each figure, the setting of elastic body 19 is eliminated.The displacement limiting mechanism 25 of Fig. 6 a illustrates the situation being provided with hooking sheet 26, and this hooking sheet 26 is from the stop component 13 of post parts 1A, further until the upside of exempting to shake post 10 is extended in the mode with gap G.In addition, the displacement limiting mechanism 25 of Fig. 6 b illustrates the situation having the binder bolt 27 of the length of gap G to link on apparatus between the pressing flange 12 of post parts 1A and the abutment flange 17 exempting to shake post 10.In addition, the displacement limiting mechanism 25 of Fig. 6 c illustrates the situation being provided with latch for printed circuit 28, and this latch for printed circuit 28 is from the pressing flange 12 of post parts 1A, and the length with the upside of the pressing flange 12 relative to post parts 1B with gap G extends.In addition, described displacement limiting mechanism 25 can also adopt the shape doubling as stop component 13 as previously mentioned, in addition, can also arrange the unallied independent object formed with stop component 13.

In the above-described embodiments, action as follows.

Fig. 1 a illustrates the post 1 during inactive state, the smooth bearing surface 9 exempting to shake post 10 that the load putting on the goods of lateral column parts 1B is close to via the flat end 7 with post parts 1B and the flat end 6 of post parts 1A be close to the smooth bearing surface 8 exempting to shake post 10 are passed to lower lateral column parts 1A, and post 1 keeps the state of straight line.

In addition, in fig 1 a, even if when the rocking of the smaller acceleration S1 in consequence of an earthquake and in post 1 occurred level direction, described post 1 also remains linear state.That is, be close to by the flat end 6,7 of the pressing flange 12 by post parts 1A, 1B and the smooth bearing surface 8,9 of exempting to shake one end 10a of post 10 and the abutment flange 17 of the other end 10b confining force caused, post 1 remains the state of straight line.Now, because smooth end face 6,7 and smooth bearing surface 8,9 whole is close to due to load, therefore large because being close to the confining force caused, the triggering loads tilting required to make to exempt to shake post 10 becomes large.

And, in smooth end face 6,7 and smooth bearing surface 8,9, due to by clinging force additional by furthering of causing of elastic body 19, even if therefore due to the earthquake of middle and small scale, there is rocking of smaller acceleration S1 in the horizontal direction, described in exempt to shake the state that the bearing surface 8,9 of post 10 and the end face 6,7 of post parts 1A, 1B also keep being close to.

On the other hand, in the generation due to extensive earthquake, when there is the rocking of large acceleration S2 as shown in Figure 1 b in the horizontal direction, post parts 1A, 1B become the state to horizontal direction relative movement.Now, exempt to shake one end 10a of post 10 and other end 10b can not move due to the bight of the inner face and end face 6,7 that are connected to stop component 13, therefore when exceed based on the load of the triggering loads scope be close to of end face 6,7 and bearing surface 8,9 act on exempt from shake post 10, as shown in Figure 1 b, exempt from shake post 10 the left and right ora terminalis (limit) of bearing surface 8,9 to be started as fulcrum E tilt.So tilt by exempting from shake post 10, the rocking of large acceleration S2 of the horizontal left and right directions of subtend carries out exempting from shake.In addition, when the rocking of large acceleration S2 occurs along horizontal depth direction, similarly tilt to depth direction by exempting from shake post 10, shake is exempted to the rocking of large acceleration S2 of horizontal depth direction.Now, if form the width B of left and right directions of bearing surface 8,9 and the depth length of depth direction significantly, then exempt from shake post 10 and become and to be difficult in the lateral direction and depth direction tilts, thus can set large triggering loads.

So, by simply exempting to shake the post 1 that structure 5 is located at the tiered warehouse facility 100 (structure) shown in Fig. 7 a, Fig. 7 b by forming from, shake can effectively be exempted to the load acting on post 1 due to earthquake.That is, by arranging the trigger mechanism 11 of the triggering loads at random setting level two direction of principal axis X, Y, can play level two direction of principal axis X, Y of tiered warehouse facility 100 are required exempt from shake characteristic effectively to exempt to shake

As shown in Fig. 2 a, Fig. 2 b, Fig. 2 c, when elastic body 19 being configured at the limit 24y of limit 24x and the depth direction of exempting from the width shaking post 10, consider due to the configuration variance of elastic body 19 impact of exempting to shake characteristic that level two direction of principal axis X, Y give from making to exempt from the horizontal stiffness shaken when post 10 is out of shape in the horizontal direction.

First, consider that the elastic body 19 configured as Fig. 2 a, Fig. 2 b, Fig. 2 c is to the contribution of exempting from the horizontal stiffness shaking post 10.If the axial load applying of level two is in exempting to shake post 10, then exempt to shake post 10 for being tilted as center by the fulcrum E (with reference to Fig. 1 b) of lower end.Now, because elastic body 19 is to resist the mode effect of exempting from the inclination of shaking post 10, therefore recuperability is to exempt from for what tilt the mode effect that shake post 10 returns to plumbness.

If the height exempting to shake post 10 is h, the width exempting to shake post is B, the depth length of exempting to shake post is B', as shown in Figure 2 d, horizontal stiffness khoX when the upper end making to exempt to shake post 10 tilts along the direction of principal axis X parallel with the limit 24x of width is square proportional due to arm spring power and length, therefore as shown in formula 1.

[mathematical expression 1]

L1: elastomeric phase mutual edge distance

L2: elastomeric scope is set

Ko: spring constant.

Similarly, as shown in Fig. 2 (d), the horizontal stiffness khoY when upper end of exempting to shake post 10 is tilted along the direction of principal axis Y parallel with the limit 24y of depth direction is as shown in formula 2.

[mathematical expression 2]

At this, if establish L1=B/4, L2=B/2, be then

[mathematical expression 3]

[mathematical expression 4]

, relative to the direction of principal axis X shown in Fig. 2 d, the direction of principal axis according to Fig. 2 e, can to obtain on horizontal stiffness 1.73 times, different the exempting from of 1.3 times shakes characteristic on the natural period.Certainly, above-mentioned is an example, can give arbitrary difference exempt to shake characteristic by the configuration of elastic body 19 to level two direction of principal axis X, Y.

Thus, in the tiered warehouse facility 100 shown in Fig. 7 a, Fig. 7 b, make to exempt to shake the triggering loads of structure 5, the direction of natural period step-down as one man configures with the direction of exempting to shake effect for improving tiered warehouse facility 100.That is, configure in the mode that the direction of limit 24x extension arranging the width of the elastic body 19 of Fig. 2 a is consistent with the direction of principal axis X in the direction for narrower width W in the tiered warehouse facility 100 of Fig. 7 b.Thereby, it is possible to improve the direction of the narrower width W of Fig. 7 b exempt from shake effect.On the other hand, for compared with the direction of not wishing under side crops industry to exempt to shake structure 5 action, triggering loads is made to become the direction of the limit 24y extension of the depth direction of large Fig. 2 a unanimously.

As shown in Fig. 2 a, Fig. 2 b, Fig. 2 c, by at two post parts 1A, 1B and exempt to shake between post 10, the elastic body 19 of varying number is configured at the limit 24y of the limit 24x of width and depth direction, can simply to be formed the triggering loads on easily setting level arbitrarily two direction of principal axis X, Y.

As shown in Fig. 1 a, Fig. 1 b, Fig. 4 a, Fig. 4 b, Fig. 4 c, Fig. 4 d, due to stop component 13 from two post parts 1A, 1B with surround exempt from shake one end 10a of post 10 and the mode of other end 10b give prominence to, therefore can by simply form formed exempt from shake post 10 tilt time fulcrum E.

As shown in Fig. 1 a, Fig. 1 b, Fig. 2 a, because the ora terminalis of the flat end 6,7 by two described post parts 1A, 1B or the ora terminalis of smooth bearing surface 8,9 of exempting to shake post 10 form fulcrum E, therefore can support to exempt to shake large load when post 10 tilts by the fulcrum E of straight line.

As shown in Fig. 1 a, Fig. 1 b, Fig. 5 a, Fig. 5 b, due to described elastic body 19 with by two post parts 1A, 1B flat end 6,7 and described in exempt to shake post 10 the fulcrum E that formed of smooth bearing surface 8,9 compared be configured at inner side (exempting to shake the center axis of post 10), therefore trigger mechanism 11 can not stretch out significantly to the outside of post 1, thus can realize small-sized exempting from and shake structure 5.

As shown in Fig. 5 a, Fig. 5 b, if arrange convex stop component 20 chimeric each other and concavity stop component 21 at two post parts 1A, 1B with exempting to shake between post 10, then can prevent exempting from shake post 10 and move to horizontal direction relative to two post parts 1A, 1B simply to construct.

As shown in Fig. 6 a, Fig. 6 b, Fig. 6 c, owing to being provided with displacement limiting mechanism 25, the restriction of this displacement limiting mechanism 25 because of described in exempt to shake that the inclination of post 10 causes exempts from shake post 10 and the displacement between two post parts 1A, 1B, therefore the inclination of exempting from shake post 10 can be limited by forming simple displacement limiting mechanism 25.

In the tiered warehouse facility 100 with rigid different on level two direction of principal axis, the side lower to the axial triggering loads of level two had owing to being made to exempt to shake structure 5 by the configuration of elastic body 19 is as one man configured at post 1 with the direction of exempting to shake effect for improving tiered warehouse facility 100, therefore possess outstanding exempting from and shake effect, goods can be alleviated because of earthquake from the problem that the shelf of tiered warehouse facility 100 falls.

In addition, exempt from described in shake the post that structure 5 can be applicable to the various structure such as boiler steel structure, sky parking, handling facilities beyond tiered warehouse facility 100.

In addition, the present invention does not limit above-described embodiment certainly, without departing from the spirit and scope of the invention can all changes in addition.
