164 screws 168 screwed togather are protruded through a part for check plate 164 and thread spindle from the lower surface of check plate 164.In screw
168 top is screwed with the nut 172 contacted with the upper surface of the 3rd truss support angle section 61.
The gasket 166 with specific thickness is suitably provided between the 3rd truss support angle section 61 and check plate 164.
Screw 168 is formed through in the hole of gasket 166.Screw 168 between nut 172 and check plate 164 to clip the 3rd truss support
The mode of angle section 61 and gasket 66 is fixed on the 3rd truss support angle section 61.
By proper choice of thickness, the number etc. of gasket 166, the 3rd truss support angle section 61 and check plate 164 can be adjusted
Between interval, the height i.e. until from base plate 80 to the 3rd truss support angle section 61.
Bottom plate 162 is the plate-shaped member for having specific thickness.On bottom plate 162, dash forward with from the lower surface of check plate 164
It is formed with through-hole 174 on the 168 corresponding position of screw gone out.In diameter of the through-hole 174 with the thread spindle than screw 168 is big
Diameter.It is being set between the stringer board 170 of directing plate 160 and the 3rd truss support angle section 61, is being provided with from 16 side of the 1st ground
Several gap W1 (with reference to Fig. 6).
Then, the function and effect of escalator 11 are illustrated.Assuming that the earthquake of small-scale or middle scale has occurred.
Since the 3rd truss support angle section 61 of escalator 11 is engaged by rotating support portion 140 with base plate 80, on the 1st ground
The displacement generated between face 16 and the 2nd ground 18 mainly passes through the opposite shifting between the 4th truss support angle section 67 and base plate 81
It moves to absorb.4th truss support angle section 67 has the horizontal plate 73 of sufficient length, therefore by opposite between base plate 81
The earthquake of scale degree during movement can be coped with fully.
In addition, at this point, in semifixed portion A, centered on the threaded 144 of rotating support portion 140, in sliding part 142
Bottom plate 162 and directing plate 160 between generate sliding, the 3rd truss support angle section 61 suitably rotates relative to base plate 81.By
This, truss 14 and the lateral displacement on the 1st ground 16 are absorbed.The reason is that the 1st prevents the mounting hole 130 of falling device 90
For slot hole, therefore the lateral wobble for preventing from also suitably following in falling device 90 truss 14 the 1st, will not apply excessive negative
It carries.Also, when truss 14 larger fascinates relative to the 1st ground 16, bottom plate 162 etc. is abutted with stringer board 170, inhibits truss
140 lateral wobble.
On the other hand, it is assumed that have occurred extensive earthquake, and the shape to be contacted from the 2nd ground 18 with downside layer horizontal part 28
State acts the mode active force for further reducing the interval between the 1st ground 16 and the 2nd ground 18.Then, via the 3rd truss support
Angle section 61 is to 144 acting shear power of threaded.Also, reach the stage of specified value in shearing force, threaded 144 is from notch 158
Place's fracture.Truss 14 avoids acting on truss 14 itself excessive compressing force further to the 1st ground 16 as a result,.
Later, when the interval between the 1st ground 16 and the 2nd ground 18 expands again, in upper layer horizontal part 26,
Relative movement is generated between 3 truss support angle sections 61 and base plate 80, in downside layer horizontal part 28, in the 4th truss support angle section
Relative movement is generated between 67 and base plate 81, and copes with the variation at the interval between the 1st ground 16 and the 2nd ground 18.
But the length of the lap of the 3rd truss support angle section 61 than the 4th truss support angle section 67 relative to truss 14
The length of lap is short, therefore when interval becomes larger, sometimes the hook between the 3rd truss support angle section 61 and the 1st ground 16, i.e.
Hook between base plate 80 can be detached from.
Even if the 3rd truss support angle section 61 is detached from from the hook of base plate 80, the effect for preventing falling device 90 by the 1st
And upper layer horizontal part 26 is also supported by base plate 80, truss 14 is not fallen out.
In turn, when the 3rd truss support angle section 61 is detached from from the hook of base plate 80, as shown in figure 9, washer 146 is from spiral shell
Line pin 144 is detached from.In addition, as shown in figure 11, bottom plate 162 is detached from from screw 168.In turn, when the threaded by notch 158
When 144 fracture, pin portion 156 falls the depth dose for the clearance D 1 being arranged between base portion 150, sinks to pin maintaining part 148
The inside in hole.
As a result, in rotating support portion 140, it is formed with up and down between the 3rd truss support angle section 61 and pin maintaining part 148
The gap in direction is formed with the gap of upper and lower directions in sliding part 142 between screw 168 and directing plate 160.Thus, i.e.,
Just due to rocking for earthquake and truss 14 is again close to the 1st ground 16, in rotating support portion 140, sliding part 142, the 3rd truss
Bearing angle section 61 will not be fixed on the component of base plate 80 with residual, specifically sell maintaining part 148, the hair of directing plate 160
Raw collision.Truss 14 can be restored on the base plate 80 on the 1st ground 16 as a result,.In addition, if setting makes steel wire and gasket
146, the mechanism appropriate of connection of bottom plate 162 etc. can prevent gasket 146, bottom plate 162 from being fallen towards lower layer then when being detached from.This
Outside, the component that can be detached from is not limited to gasket 146, bottom plate 162.
In addition, in escalator 11, on the 1st ground 16, using on the length direction of truss 14 length it is shorter
3rd truss support angle section 61, therefore the installation space on the 1st ground 16 can be shortened.
As described above, escalator 10 according to the present embodiment, even if in truss 14 and the 1st ground 16 etc.
Between interval be more than range that the 1st previous truss support angle section 60 copes with and it is widened in the case of, can also pass through
1st prevents falling device 90 from carrying out lattice 14, can prevent truss 14 from being fallen from the 1st ground 16 etc..
In escalator 10, the 1st prevents falling device 90 from not exposing on the 1st ground 16, also, does not make the 1st ground
The installation space of escalator on 16 expands, so even can also be arranged in the case where being unable to fully ensure space.
Due to preventing falling device 90 from keeping truss 14 from left and right by the 1st, so the transverse direction of truss 14 can be inhibited to shake
It shakes, the movement of truss 14 can be made to stablize.
Escalator 11 according to the present embodiment, rotating support portion 140 can be by being screwed into the 3rd purlin by threaded 144
Frame supports angle section 61 and the 3rd truss support angle section 61 is sticked in base plate 80, therefore operation is easy.
When improveing the escalator set as the escalator 10 of present embodiment, without making truss 14 from building structure
The divine force that created the universe 12 moves, therefore can construct with lower cost and within a short period of time.
