(3-2) Structure for Attaching the Rope 40 to the Lower Horizontal Frame Member 15 Next, a structure for attaching the central portion of the rope 40 to the lower horizontal frame member 15 of the truss 10 will be described.

As shown in FIGS. 2 and 5 to 7, a plate-shaped first holding member 60 is arranged on the outer surface of the horizontally arranged lower horizontal frame member 15. The first holding member 60 is rectangular, and the length of the first holding member 60 in the left-right direction is shorter than the distance between the pair of left and right vertical frame members 13, 13. A pair of left and right hooks 72, 72 project from the lower parts on both the left and right sides of the first holding member 60. The pair of left and right hooks 72, 72 are welded to the outer surface of the lower horizontal frame member 15. The upper portion of the first holding member 60 projects upward from the upper end portion of the lower horizontal frame member 15.

As shown in FIG. 6, a pair of left and right guide plates 70, 70 are welded to both sides of the first holding member 60 projecting from above the lower horizontal frame member 15. The rope 40 is arranged in the left-right direction between the lower end of the guide plate 70 and the upper end of the lower horizontal frame member 15. A curved surface 68 is formed at the lower ends on both the left and right sides of the guide plate 70. The curved surface 68 is a guide surface for preventing the rope 40 arranged in the left-right direction from bending at a right angle when the rope 40 is bent in the vertical direction.

As shown in FIGS. 5 to 7, a pair of left and right second sandwiching members 62 is formed on the inner surface of the lower horizontal frame member 15, that is, the surface facing the first sandwiching member 60 with the lower horizontal frame member 15 interposed therebetween. , 62 are arranged. The pair of left and right second holding members 62, 62 are rectangular plates arranged at the left and right corners of the first holding member 60, respectively. That is, the pair of left and right second holding members 62 are located at positions corresponding to the pair of left and right guide plates 70, and are arranged on the inner surface of the lower horizontal frame member 15. Then, the lower horizontal frame member 15 and the lower portion of the second holding member 62 are fixed by a plurality of bolts 64. Further, the upper portion of the second holding member 62 is fixed to the guide plate 70 and the first holding member 60 by a plurality of bolts 66.

As shown in FIGS. 2 and 5, the rope 40 can be fixed above the lower horizontal frame member 15 by the first holding member 60, the guide plate 70, and the pair of left and right second holding members 62.

(3-3) Structure for Protecting the Rope 40 As described above, as shown in FIGS. 3 and 4, the left and right ends of the rope 40 are formed by a pair of left and right clamp portions 42, 42 provided on the anchor plate 26. It is fixed, and as shown in FIGS. 2, 5 and 6, the central portion of the rope 40 is fixed by the first holding member 60, the guide plate 70 and the second holding member 62.

By the way, in the method of arranging the rope 40 as described above, the rope 40 is arranged below the horizontal plate 34 of the support angle 30, and may be pinched by the anchor plate 26 and damaged. Further, the rope 40 may be damaged by the horizontal plane of the skeleton 2 and the corners of the cliff portion 5. Therefore, as shown in FIG. 5, the protective member 80 is arranged below the support angle 30 so as not to damage the rope 40.

As shown in FIG. 8, the metal protective member 80 includes a horizontal protective portion 82 of a long and thin rectangular parallelepiped, and a vertical protective portion 84 vertically hung downward from the front side of the horizontal protective portion 82. Is provided with a horizontal groove 86 extending in the longitudinal direction, and the vertical protection portion 84 is provided with a vertical groove 88. The horizontal groove 86 and the vertical groove 88 are continuously connected by an arc-shaped connecting groove 90.

As shown in FIGS. 2 and 5, the rope 40 extending in the front-rear direction from the clamp portion 42 is housed in the lateral groove 86 of the protective member 80, and then stored in the connecting groove 90 and the vertical groove 88, and then the protective member. It is exposed from 80 and extends toward the lower horizontal frame member 15.

When the protective member 80 is attached to the rope 40, the protective member 80 is laid on its side on the anchor plate 26 with the vertical protective portion 84 protruding from the cliff portion 5. Next, the rope 40 is stored in the lateral groove 86 of the lateral protection portion 82. Next, the protective member 80 is rotated by 90 ° to make the vertical protective portion 84 in the vertical direction along the cliff portion 5. Next, the rope 40 is stored in the vertical groove 88.

As a result, since the metal protective member 80 is sandwiched between the horizontal plate 34 of the support angle 30 and the anchor plate 26, the rope 40 housed inside the protective member 80 is not damaged. Further, since the connecting groove 90 connecting the horizontal groove 86 and the vertical groove 88 has an arc shape, the rope 40 bends smoothly without bending at a right angle and is not scratched. Further, since the surface of the rope 40 is coated with a synthetic resin, the wire rope inside can be protected.

(4) Role of Rope 40 The role of the rope 40 fixed to the anchor plate 26 and the truss 10 as described above will be described.

An earthquake occurs, and as shown in FIG. 9, the mortar 28 is destroyed, and the support angle 30 of the truss 10 is displaced from the skeleton 2 of the building 1.

However, the left and right ends of the rope 40 are fixed to a pair of left and right clamp portions 42, 42 on the anchor plate 26, and the central portion of the rope 40 is fixed to the lower horizontal frame member 15 of the truss 10. Therefore, the truss 10 is suspended from the anchor plate 26 by the rope 40, and the truss 10 does not fall from the building 1.

(5) Effect According to the present embodiment, even if the support angle 30 of the truss 10 is disengaged from the anchor plate 26 due to an earthquake, the truss 10 does not fall because it is suspended by the rope 40.

Further, when the rope 40 is pulled toward the truss 10 side at the time of the earthquake, the wedge portion 52 of the clamp portion 42 becomes thinner toward the truss 10 side and thicker toward the side opposite to the truss 10 side. Therefore, even if the rope 40 moves to the truss 10 side, the holding force between the fixing portion 46 and the wedge portion 52 is strengthened by the wedge effect, and the rope 40 does not come off from the clamp portion 42. Further, in the rope 40, the portion extending from the truss 10 is clamped between the pressing surface 48 of the fixing portion 46 and the wedge portion 52, and then the left end portion of the rope 40 is bent in the left-right direction via the curved surface 50. , The rope 40 is not scratched when bent.

Further, since the metal protective member 80 is arranged at the lower end of the support angle 30, the rope 40 is not directly sandwiched between the support angle 30 and the anchor plate 26 and is not scratched. Further, when the rope 40 bends from the front-rear direction to the vertical direction, it is bent by the arc-shaped connecting groove 90, so that it is not scratched. Further, since the surface of the rope 40 is coated with a synthetic resin, the wire rope inside can be protected.

Further, the central portion of the rope 40 attached to the lower horizontal frame member 15 is arranged in the left-right direction, and both sides thereof are bent in the vertical direction, and this bent portion is perpendicular to the curved surface 68 of the guide plate 70. Since it can be bent without bending, it will not be scratched.

Further, since the rope 40 is only housed in the vertical groove 88 of the protective member 80, when an earthquake occurs and the truss 10 is separated from the cliff portion 5, the rope 40 is a protective member according to the degree of separation. The truss 10 can be suspended away from the 80 without hindering the movement of the rope 40.

Further, since the pair of left and right hooks 72, 72 protruding from below are hung on the lower horizontal frame member 15, the first holding member 60 does not come off even if a lifting force is applied by the rope 40.

Change example

In the above embodiment, in the clamp portion 42, the cuneus portion 52 is arranged with respect to the rope 40 extending in the front-rear direction. Instead, the cuneus portion 52 is provided after bending the rope 40 extending in the front-rear direction and extending in the left-right direction. You may arrange it. Also in this case, the wedge portion 52 is tapered in the direction of the rope 40 on the truss 10 side so that the wedge portion 52 can be fixed when the rope is pulled toward the truss 10.

In the above embodiment, it has been described by applying it to the escalator 100, but it may be applied to a moving walkway instead.
