In the embodiment of Fig. 1 a, Fig. 1 b, by two post parts 1A, 1B, be configured between these two post parts 1A, 1B exempting from shake post 10 and be located at two post parts 1A, 1B and exempt from the trigger mechanism 11 shaken between post 10 form described in exempt to shake structure 5.
But, exempt from described in replacement shake structure 5, can also by described plate-shaped member 12,12', be configured between this plate-shaped member 12,12' exempting from shake structure 5 and be located at described plate-shaped member 12,12' and exempt from the trigger mechanism 11 shaken between structure 5 realize with the structure of exempting to shake independently blocking exempt from shake structure 5.The shake structure 5 of exempting from of blocking like this easily can load and easily be configured between the such parts in the midway of post parts 1A, 1B of structure or the beam 2 of formation structure and beam 2.
And, according to described trigger mechanism 11, when two post parts 1A, 1B are to horizontal direction relative movement, be connected to the inner face of stop component 13 by the ora terminalis of exempting from the end face 6,7 shaking post 10, prevent exempting from shake post 10 and move outside horizontal direction relative to two post parts 1A, 1B.Therefore, the inner face of described stop component 13 becomes fulcrum E with the ora terminalis of exempting from the end face 6,7 shaking post 10, exempts from shake post 10 and starts to dump.In addition, when exempting from shake post 10 described in making and tilting, as shown in Fig. 1 a, 1b, between the outside shaking post 10 at the inner face and exempting from of stop component 13, substitute and to be formed along with deviating from from plate-shaped member 12,12' from the gap 14 of exempting to shake post 10 and deviating from, post 10 given clearance parallel with the external surface arranged between stop component 13 with exempt to shake post 10 can also be shaken described exempting from.
Fig. 1 c, Fig. 1 d illustrate other examples of described trigger mechanism 11.Described trigger mechanism 11 owing to configuring with having laterally zygomorphic shape, therefore in Fig. 1 c, figure d, only illustrates and is exempting to shake the trigger mechanism 11 arranged between the lower end of post 10 and the post parts 1A of downside.The trigger mechanism 11 of Fig. 1 c forms stop component 13, this stop component 13 is made up of protuberance, this protuberance is given prominence to from plate-shaped member 12 in the mode formed with exempt to shake gap 14' parallel outside post 10, and, be extruded with protuberance 26 in the periphery of exempting from one end 10a (lower end) shaking post 10.Thus, described in exempt from shake post 10 be connected to stop component 13 by protuberance 26 and be prevented from moving to horizontal direction, and, exempt from shake post 10 can using protuberance 26 as fulcrum E start tilt.Described protuberance 26 can also be located at the inner face with the near stop component 13 of the plate-shaped member 12 being located at post parts 1A above.In addition, described protuberance 26 can exempt from multiple, spaced apartly to arrange side by side around shake post 10, in addition, can also exempt to arrange around shake post 10 continuous annular.
In addition, the trigger mechanism 11 of Fig. 1 d is provided with when stop component 13 is arranged with the mode of exempting to shake gap 14' parallel outside post 10 to be formed, the extension 10'(flange part relative to one end of post parts 1B is given prominence to laterally).Thus, exempt from shake post 10 and be connected to stop component 13 by the outboard end of described extension 10' and be prevented from moving to horizontal direction, and exempting from shake post 10 can start to tilt as fulcrum E using the outboard end of extension 10'.In addition, although in Fig. 1 c, Fig. 1 d, show stop component 13 to form situation about arranging with the mode exempting to shake gap 14' parallel outside post 10, but as shown in Figure 1a, the mode that stop component 13 can also strengthen towards the length direction central side exempting to shake post 10 with interval tilts.
In addition, between the bearing surface 8,9 shaking post 10 at the end face 6,7 and exempting from of described plate-shaped member 12,12', can also be situated between the flaky elastic material 28 having and formed by thin elastomeric material etc.
Fig. 2 a ~ Fig. 2 d illustrates the shape example of stop component 13, and this stop component 13 forms the described trigger mechanism 11 being located at two post parts 1A, 1B and exempting to shake between post 10.Because form the stop component 13 being located at the trigger mechanism 11 of two post parts 1A, 1B there is laterally zygomorphic shape, so in Fig. 2 a ~ Fig. 2 d, the stop component 13 arranged at the plate-shaped member 12 of lower lateral column parts 1A is only shown.
Fig. 2 and Fig. 1 a is same, the situation of the stop component 13 that the mode of the whole periphery of exempting from one end 10a shaking post 10 described in being provided with to surround is given prominence to is shown, Fig. 2 b illustrates the variation of stop component 13, the situation being only provided with stop component 13' in 4 corner portion of plate-shaped member 12 is shown, Fig. 2 c illustrates the situation being only provided with stop component 13'' in 4 edge of plate-shaped member 12.Fig. 2 d shows the mode of the periphery to surround one end 10a exempting to shake post 10 relative to plate-shaped member 12, is provided with the situation of the stop component 13 of the projection 15 being based upon stud (stud) parts.
In addition, although in the embodiment of Fig. 1 a ~ Fig. 1 d, Fig. 2 a ~ Fig. 2 d, describe the situation possessing the stop component 13 as trigger mechanism 11 at two post parts 1A, 1B, described stop component 13 can also be located at one end 10a and other end 10b that exempt to shake post 10.
< exempts from the shake width of post and the setting > of depth
The width or depth of exempting from the post 1 shaking structure 5 if increase, then can be used in exempting from the increase of the triggering loads shaking structure 5 and exempting from the increase of the rigidity of shaking structure 5.
Exempt from the cross sectional shape shaking post 10 described in Fig. 3 a ~ Fig. 3 d illustrates, this exempts from the shape of the bearing surface 8,9 of cross sectional shape performance end 10a, 10b of shaking post 10.Fig. 3 a illustrates that the cross sectional shape exempting to shake post 10 is that above width B 1 and depth B2 are the foursquare situation of formed objects at level two direction of principal axis (X, Y), Fig. 3 b illustrates that the cross sectional shape exempting to shake post 10 is on level two direction of principal axis (X, Y), the rectangular situation varied in size of width B 1 and depth B2.In addition, described in exempt to shake the cross sectional shape of post 10 and can also have the octagon shape shown in Fig. 3 c of foursquare four clipped corners of Fig. 3 a, or, can also have the elongated octagon-shaped shown in Fig. 3 d of rectangular four clipped corners of Fig. 3 b.In addition, described in exempt to shake the cross sectional shape of post 10 can adopt the polygons such as hexagon except above-mentioned shape, or, circle or ellipse can be adopted.
In the above-described embodiments, action as follows.
Fig. 1 a illustrates the post 1 during inactive state, the load putting on the goods of lateral column parts 1B shakes via the smooth bearing surface 9 and exempting from that the flat end 7 and exempting from of post parts 1B shakes post 10 the post parts 1A that the smooth bearing surface 8 of post 10 and the flat end 6 of post parts 1A are passed to downside, and post 1 keeps linear state.
In addition, in fig 1 a, even if when there is rocking of smaller acceleration S1 in the horizontal direction at post 1 in consequence of an earthquake, described post 1 also keeps linear state.
That is, by putting on the load of post 1, the end face of described post parts 1B 7 and the bearing surface 9 exempting to shake post 10 abut and are crimped, and, exempt from the shake bearing surface 8 of post 10 and the end face 6 of post parts 1A abuts and is crimped.Now, at post parts 1A, 1B, owing to being provided with the stop component 13 surrounding and exempt to shake one end 10a of post 10 and the periphery of other end 10b, therefore preventing exempting from shake post 10 and move outside horizontal direction.Thus, even if due to the earthquake of middle and small scale, there is rocking of smaller acceleration S1 in the horizontal direction, due to the Trigger Function that the end face 6,7 of exempting from the bearing surface 8,9 and post parts 1A, 1B that shake post 10 abuts, exempt from shake post 10 can not tilt, post 1 remains linear state.Now, if exempting from shown in Altered Graphs 3a ~ Fig. 3 d shakes the size of the width B 1 that abuts with the end face 6,7 of post parts 1A, 1B of the bearing surface 8,9 of post 10 and depth B2, then can change and exempt from the size that shake post 10 starts the triggering loads of inclination.If set described width B 1 and depth B2 significantly, then exempt to shake post 10 and start the triggering loads change of inclination greatly.
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 on horizontal left and right directions, 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 because the ora terminalis of bearing surface 8,9 is connected to the inner face of stop component 13, therefore when the load exceeding triggering loads scope that the abutting by end face 6,7 and bearing surface 8,9 causes act on exempt from shake post 10, as shown in Figure 1 b, exempt from shake post 10 ora terminalis 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 set the size of left and right directions width of bearing surface 8,9 and the size 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, simply exempting to shake structure 5 by possessing formation, on level two direction of principal axis, can effectively exempting from shake to acting on rocking of tiered warehouse facility 100 (structure) post 1.
As previously mentioned, the shake post 10 of exempting from tilted due to earthquake is done in order to make the restorable power of inclination centered by described fulcrum E, therefore under the state of rocking end, and two post parts 1A, 1B and exempt from shake post 10 and restore as shown in Figure 1a to linear state.
As shown in Fig. 1 a ~ Fig. 1 d, due to following trigger mechanism 11, therefore coupled columns 1 can be carried out on level two direction of principal axis, effectively carry out exempting from shake by forming simple trigger mechanism 11, this trigger mechanism 11 arranges the stop component 13 given prominence in the mode of surrounding one end 10a and other end 10b that exempt from shake post 10 from the plate-shaped member 12 being located at two post parts 1A, 1B, to prevent the movement to horizontal direction of exempting to shake post 10, and from fulcrum E, exempt from the inclination of shaking post 10.
Such as, for in the direction applied the large load of rocking during automated warehouse storage goods for tiered warehouse facility 100, near with the distance of adjacent structure, the direction making to exempt to shake structure 5 action is not wanted in the earthquake of middle and small scale degree, comparatively large by making not want the size B making to exempt from the direction shaking structure 5 action, can set significantly exempt to shake structure 5 exempt from shake the triggering loads that post 10 starts to tilt.Namely, as shown in Fig. 3 a, Fig. 3 c, when making the width B 1 of level two direction of principal axis (X, Y) of exempting from the cross sectional shape shaking post 10 identical with the size B of depth B2, can at level two direction of principal axis (X, Y) triggering loads that above setting is identical.In addition, as shown in Fig. 3 b, Fig. 3 d, when making to exempt from the width B 1 of level two direction of principal axis (X, Y) of the cross sectional shape shaking post 10 and the size of depth B2 is different size, the triggering loads on level two direction of principal axis (X, Y) differently can be set.
In the trigger mechanism 11 shown in above-described embodiment, two post parts 1A, 1B and exempt to shake post 10 and be retained as straight line by the abutting of flat end 6,7 and smooth bearing surface 8,9.And when two post parts 1A, 1B are to horizontal direction relative movement, one end 10a and the other end 10b that exempt from shake post 10 described in being prevented by stop component 13 are moved outside horizontal direction relative to two post parts 1A, 1B.Therefore, exempt from shake post 10 tilt centered by fulcrum E, thereby, it is possible to by form simply exempt from shake structure 5 on level two direction of principal axis to structure effectively exempt from shake.That is, can exempt to shake to the horizontal omnirange of intersecting with level two direction of principal axis (X, Y).
At this, between the bearing surface 8,9 shaking post 10 at the end face 6,7 and exempting from of described plate-shaped member 12,12', if arrange the flaky elastic material 28 formed with TR thin rubber etc., then can suppress plate-shaped member 12,12' and exempt from the contact load of the impact of shaking post 10.Described flaky elastic material 28 can also utilize expanded material as the replacement of elastomeric material.In this case, although recuperability diminishes compared with elastomeric material, the inhibition improving contact load can be expected.
