A plurality of steps 5 circulating in a step moving space, a side panel 6 as an exterior panel covering left and right outer surfaces of the truss 4, and an exterior panel covering a bottom surface of the truss 4 , A pair of left and right deck boards 8 covering a pair of left and right upper surfaces of the truss 4, and a pair of left and right ledge skirts arranged to cover the left and right step moving spaces of the truss 4. An integrated member 9, a plurality of balustrades 10 erected on the deck board 8 at intervals, a handrail belt 11 laid over the upper surface of the plurality of balustrades 10, a handrail belt 11, a deck board 8 and each balustrade And a glass panel 12 which is disposed in each space surrounded by 10. The plurality of steps 5 circulate by receiving the rotational force of a driving device (not shown) via a power transmission means such as the drive chain 13.
[0010]
The truss 4 is configured by assembling a large number of horizontal beams 4a horizontally arranged at upper and lower positions and oblique beams 4b arranged obliquely between the horizontal beams 4a at upper and lower positions.
[0011]
Next, the mounting structure of the side panel 6 and the bottom panel 7 covering the outer periphery of the truss 4 will be described with reference to FIGS. As shown in FIGS. 2 to 4, first brackets 20 are fixed to the lower surfaces of the left and right horizontal beams 4 a at the lower position, and second brackets 21 extending downward are screwed to the respective first brackets 20. Have been. A plurality of hook members 22 are screwed to the left and right first brackets 20 at appropriate intervals in the longitudinal direction of the truss 4, and each hook member 22 is disposed at a position facing the side surface of the truss 4. I have. Hook members 23 arranged in the horizontal direction are connected between the left and right opposed second brackets 21, respectively. Each hook member 23 is arranged at a position facing the bottom side of the truss 4.
[0012]
In addition, auxiliary plates 24 are fixed to appropriate positions on the inner surface side of the side panel 6, and a hook member 25 is screwed to each auxiliary plate 24. Similarly, a hooked member 26 is screwed to an appropriate position on the inner surface side of the bottom plate 7.
[0013]
On the other hand, the ledge / skirt integral member 9 is made of stainless steel as shown in detail in FIG. 5, and an inner ledge portion 9a and a skirt portion 9b are integrally formed. The ledge / skirt integral member 9 is fixed to the truss 4 side by screwing or hooking means, its upper edge substantially abuts on the glass panel 12, and its lower edge goes deeper into the lower position than the upper surface of the step 5. Position has been reached.
[0014]
As described above, in the escalator 1 described above, the side panels 6 and the bottom panel 7 can be attached to the truss 4 by hooking the hook members 22 and 23 of the truss 4 on the hooked members 25 and 26 of the side panel 6 and the bottom panel 7. Therefore, the workability of attaching the side panel 6 and the bottom panel 7 is good. In addition, since welding work is not required and can be mounted by simple hooking work, mounting can be performed even by a non-technical expert. Further, the mounting position can be easily adjusted.
[0015]
Further, in the escalator 1 described above, the ledge / skirt integrated member 9 in which the inner ledge portion 9a and the skirt portion 9b are integrally formed is provided on the inner side surface of the truss 4 on the side of the step moving space. By attaching only the ledge / skirt integral member 9 to the step moving space side of 4, and by removing only the ledge / skirt integral member 9, the inner ledge portion 9a and the skirt portion 9b can be attached and detached. Therefore, the attachment workability and the removal workability of this portion are good. That is, conventionally, the step moving space side of the truss 4 has been covered by attaching two parts, the inner ledge member and the skirt member. Therefore, when removing the skirt member, it is necessary to remove the inner ledge member. Although the operation was troublesome, in the present invention, the attachment workability and the removal workability were improved for the reasons described above. In addition, the design, ordering, manufacturing, and transportation costs can be reduced by using the ledge / skirt integrated member 9 as one member.
