As a result, being set up in the pivot 42 between the horizontal part 21a and fulcrum bearing 41 of the 1st truss support angle section 21, pressed from both sides
It holds between lid 44 and the upper surface of pedestal 27.
In the present embodiment, for example, when due to earthquake and in the 1st truss support angle section 21 and the 1st angle section supporting station 25
Between generate along the length direction of truss 3 relative movement when, to 42 acting shear load of pivot.When shear-type load is more than
When the mechanical strength of the engaging portion 52 of pivot 42, pivot 42 fractures at the position of engaging portion 52.
As a result, axial element 51a, 51b of pivot 42 is separated from each other, pivot 42 is to the 1st truss support angle section 21 and the 1st jiao
The connection of material supporting station 25 is released from.
In with above such escalator 1 constituted, for example, due to earthquake and on the 1st floor of building 2
In the case of producing the relative storey displacement along the width direction of truss 3 between face 4 and the 2nd floor 5, with the pivot 42 of standing
Centered on, be fixed on 3 upper layer side horizontal part 10a of truss the 1st truss support angle section 21 and the 1st angle section supporting station 25 relatively
Rotation.
By the rotation, the relative storey displacement amount along the width direction of truss 3 can be absorbed, can avoid making truss 3
With excessive external force.
When the relative storey displacement with the width direction along truss 3 is accompanied, the 1st truss support angle section 21 and the 1st angle section branch
When relative rotation range between cushion cap 25 is more than the upper limit, the either side in stop part 30a, 30b of directing plate 28a, 28b
It is resisted against the horizontal part 21a of the 1st truss support angle section 21.As a result, the 1st truss support angle section 21 and the 1st angle section supporting station 25 it
Between relative rotation limited, the 1st truss support angle section 21 can be avoided to be collided with building 2.
On the other hand, when producing the length along truss 3 between the 1st floor 4 of building 2 and the 2nd floor 5
In the case of the relative storey displacement in direction, in small-scale earthquake or middle scale earthquake, the 2nd truss branch of on-fixed portion B is constituted
Angle section 23 is held relatively to move along the length direction of truss 3 with the 2nd angle section supporting station 26.By the movement, edge can be absorbed
The relative storey displacement amount for the length direction of truss 3 can avoid acting on truss 3 excessive compressing force.
In contrast, in the extensive earthquake extremely rarely occurred, relative storey displacement amount increases to and small-scale earthquake
Or the degree that middle scale earthquake can not compare.Therefore, it is impossible to avoid the distance between semifixed portion A and on-fixed portion B substantially
Degree reduces, and only is difficult to absorb relative storey displacement amount by on-fixed portion B.
According to the present embodiment, it is significantly reduced and truss 3 at a distance from due to semifixed portion A between on-fixed portion B
The 1st truss support angle section 21 strongly pressed towards the direction close to the 1st floor 4 in the case of, which is transferred to
Pivot 42.
Pivot 42 is by across erecting in a manner of between the 1st truss support angle section 21 and the 1st angle section supporting station 25, and conduct
The engaging portion 52 for losing reservations 57 is located at the near border of the 1st truss support angle section 21 and the 1st angle section supporting station 25.
Therefore, when pivot 42 is strongly pressed towards the direction of the 1st floor 4, to axial element 51a, 51b and with
Axial element 51a, 51b compares the smaller 52 acting shear load of engaging portion of mechanical strength.When shear-type load is more than engaging portion 52
Mechanical strength when, pivot 42 fractures at the position of engaging portion 52.
It is fixed on the axial element 51a of a side of the 1st truss support angle section 21 as a result, and is embedded in another party of fulcrum bearing 41
Axial element 51b be separated from each other, the axial element 51a of a side is in a manner of along escape groove 46 towards the blocking far from fulcrum bearing 41
It moves in the direction of wall portion 48.
As a result, the 1st truss support angle section 21 moves together with the axial element 51a of a side towards close to the direction of the 1st floor 4
Dynamic and 1 a considerable amount of the 1st gap L absorbs the relative storey displacement amount of the length direction along truss 3.
Thus, even if can avoid acting on truss 3 excessive compressing force if when extensive earthquake occurs, Neng Goufang
Only truss 3 buckle or the breakage of the 1st truss support angle section 21 and the 1st angle section supporting station 25.
Then, referring to Fig.1 0 to Figure 13 to truss 3, the 1st angle section supporting station 25 and the 2nd when having occurred extensive earthquake
Relative position relation between angle section supporting station 26 illustrates.
In the initial installation of escalator 1, as shown in Figure 1, support the 1st floor 4 supporting member 22 end face with
It is provided with the 1st gap L 1 between the front end of the upper layer side horizontal part 10a of truss 3.Equally, in the branch for supporting the 2nd floor 5
It is provided with the 2nd gap L 2 between the end face of bearing member 24 and the front end of the lower layer side horizontal part 10b of truss 3.
In turn, in the semifixed portion A being made of the 1st truss support angle section 21 and the 1st angle section supporting station 25,42 frame of pivot
It is located between the fulcrum bearing 41 on the 1st truss support angle section 21 and the 1st angle section supporting station 25.Thus, it is in the following state：In purlin
It in the on-fixed portion B of frame 3, is not limited along the displacement of the 2nd truss support angle section 23 of the length direction of truss 3, with this phase
It is right, in semifixed portion A, limited by pivot 42 along the displacement of the 1st truss support angle section 21 of the length direction of truss 3.
Figure 10 indicate for example due to extensive earthquake and the 2nd floor 5 towards the X-direction close to the 1st floor 4 relatively
The state of the amount of the 1st gap L 1 of displacement and the 2nd gap L 2.That is, the displacement of the 2nd floor 5 towards X-direction is L1+L2.
When extensive earthquake occurs, in the on-fixed portion B of truss 3, the 2nd truss support angle section 23 and the 2nd angle section branch
Cushion cap 26 is relatively moved along the length direction of truss 3, thus absorbs the relative storey displacement amount along the length direction of truss 3.
On the other hand, in the semifixed portion A of truss 3, as already mentioned, the 1st truss support angle section 21 and pivot
Axis 42 is pressed towards close to the direction of the 1st floor 4 together.Shear-type load is applied to pivot 42 as a result, pivot 42 is as folding
The engaging portion 52 of damage reservations 57 fractures.
As a result, the 1st truss support angle section 21 is released from relative to the fixation of the 1st angle section supporting station 25, the 1st truss support
Angle section 21 is moved in a manner of absorbing the 1st gap L 1.Therefore, it is possible to avoid to 3 compressive press forces of truss.
Figure 11 indicates that the 2nd floor 5 exists towards the -X direction displacement far from the 1st floor 4, truss 3 from the state of Figure 10
The state being significantly biased against towards 4 side of the 1st floor between 1st floor 4 and the 2nd floor 5.
In this state, the 2nd truss support angle section 23 is opposite along the length direction of truss 3 with the 2nd angle section supporting station 26
Ground moves, and thus absorbs the relative storey displacement amount along the length direction of truss 3.In turn, even if truss 3 is big towards 4 side of the 1st floor
Amplitude is biased against, and the 2nd truss support angle section 23 also maintains the state being hooked on the 2nd angle section supporting station 26.
Figure 12 indicates truss 3 from the state of Figure 11 towards the state of the direction displacement of the 2nd floor 5.As shown in figure 12,
1st truss support angle section 21 is followed the activity of truss 3 and is moved towards the direction far from the 1st floor 4.Therefore, even it is fixed
In the axial element 51a of a side of the horizontal part 21a of the 1st truss support angle section 21, the activity of truss 3 is also followed and in escape groove
It is moved towards the direction far from the 1st floor 4 in 46.
The lower end of the axial element 51a of one side enters in escape groove 46, therefore, when axial element 51a is towards far from the 1st
When the direction movement of floor 4, the lower end of the axial element 51a of a side is resisted against the blocking wall 48 of fulcrum bearing 41.That is, bearing
The blocking wall 48 of seat 41 limits the activity of the axial element 51 of a side.
On the other hand, Figure 13 indicate the 1st truss support angle section 21 can follow the activity of truss 3 and towards far from the 1st floor
The comparative example that the direction in face 4 moves freely through.According to comparative example, when escalator 1 truss 3 from the state of Figure 12 towards the 2nd
When 5 side displacement of floor, the 1st truss support angle section 21 is followed the activity of truss 3 and is moved towards the direction far from the 1st floor 4.
But in a comparative example, work of the 1st truss support angle section 21 towards the direction far from the 1st floor 4 can not be limited
It is dynamic.Therefore, when the relative storey displacement amount between the 1st floor 4 and the 2nd floor 5 increases, the water of the 1st truss support angle section 21
Flat portion 21a is detached from from the 1st angle section supporting station 25.As a result, as shown in the arrow of Figure 13, escalator 1 is fallen.
In contrast, link mechanism 40 according to the present embodiment, consists of, and in the state that pivot 42 fractures, permits
Perhaps axial element 51a is towards truss 3 close to the movement in the direction of the 1st floor 4, and limitation axial element 51a is towards truss 3 more than initial peace
Holding position and close to the movement in the direction of the 2nd floor 5.
Specifically, in the initial installation of escalator 1, it is welded in the resistance of the fulcrum bearing 41 of the 1st angle section supporting station 25
Retaining wall portion 48 is facing from 3 side of truss and the peripheral surface of pivot 42.
Therefore, as shown in figure 12, in the 2nd floor 5 relative storey displacement has been carried out towards the -X direction far from the 1st floor 4
Under state, even if truss 3 will carry out displacement, the blocking wall 48 of fulcrum bearing 41 from 4 side of the 1st floor towards the 2nd floor 5
The activity of axial element 51a to following the 1st truss support angle section 21 limits.
As a result, the antidetonation of escalator 1 is strengthened, falling for escalator 1 can be prevented trouble before it happens.
In turn, the blocking wall 48 of fulcrum bearing 41 limits the activity of axial element 51a, therefore can shorten the 1st purlin
Frame supports lap of the angle section 21 relative to the 1st angle section supporting station 25.Thus, it is possible to shorten the water of the 1st truss support angle section 21
The length S1 of flat portion 21a, can realize the miniaturization and lightweight of the 1st truss support angle section 21.
The engaging portion 52 of pivot 42 not specifically for adhesive layer, such as can also by be brazed, spread engagement, solid phase expand
It dissipates engagement, diffusion bonding or electric resistance welding, crimp engagement, forging welding and friction welded such crimping engagement to be formed.
