Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an exterior body such as an escalator, and a mechanism capable of extremely easily attaching a side plate as an exterior to a truss of an escalator without using a conventional welding process, and also enables a bottom plate to be easily attached. .
[0002]
[Prior art]
In a conventional escalator, steps and risers are configured to circulate on a track to carry a person, and the track section, drive section, etc. are housed in a truss that forms a box shape, and the exterior is made of iron plate, stainless steel plate or other plate Decoratively covered with body. However, the plate was directly or indirectly welded to the truss when the outer plate was attached.
[0003]
Japanese Patent Application Laid-Open No. Hei 10-236755 proposes another fixing method which avoids this welding work. It has upper mounting means that can fix the side plate to the upper beam that forms the truss on the upper part, and the lower plate can be positioned and mechanically fixed to the lower beam that forms the truss. An escalator exterior body provided with a side exterior body having a suitable lower attachment means has been proposed.
[0004]
Japanese Patent No. 2909896 discloses that the upper portion of a side plate is locked by an exterior member disposed above an upper beam, and the lower beam is provided with side plate connecting and supporting means capable of positioning vertically and horizontally. Thus, there has been proposed an escalator exterior body in which the lower part of the side plate is attached to the lower beam.
[0005]
[Problems to be solved by the invention]
In the above, one side plate is attached to the upper beam at the upper part and to the lower beam at the lower part.In the former, however, the upper part of the side plate is provided with upper fixing means capable of mechanical fixing. On the other hand, the latter is locked by an exterior member arranged above the upper beam. The lower portion is provided with mounting means capable of positioning and mechanical fixing, and is mounted on the lower beam.
[0006]
For this reason, in the known example, one side plate is securely fixed. However, even when a plurality of the side plates are continued, the side plate is similarly fixed. Must be fixed. Therefore, it is necessary to determine the height of the adjacent side plates, the left and right gaps, the degree of joining, etc., and fix them while adjusting them. This work is extremely troublesome when fixing the side plates flush, and it takes time for adjustment. Further, when the lower end of the side plate is fixedly provided on the lower beam via the connecting means, the lower end is fixed by bolts which can be inserted into the L-shaped angle and the C channel, and the opposing force against the pressure from the outside is provided. There are weak points.
[0007]
[Means for Solving the Problems]
Therefore, in the present invention, the connection and fixing of the adjacent side plates is extremely easily and reliably performed, and the operation is performed smoothly and quickly, and the side plates with high strength can be fixed. A long screw is adjustably fixed to a stud bolt erected on the frame, and a side plate fixing bracket provided with at least a folded piece is provided on the long screw so as to be adjustable, while a side plate fixing bracket has a folded piece. Each side plate is locked and fixed by contacting adjacent ends of both side plates.

【Example】
Next, the mode of use will be described.
First, the mounting bracket 3 is temporarily fixed to the stud bolt 2 at a desired position in advance with a nut 21, and the side plate mounting bracket 4 is inserted into the long screw 32 and temporarily fixed. At this time, the mounting bracket 3 and the side body mounting bracket 4 are moved forward, backward, left and right using the long holes 33 and the long holes 44, respectively, such that the folded-up piece 41 of the side plate mounting bracket 4 approaches the mounting position of the side plate 7. Move it. Then, the side plate 7 is brought outside the escalator truss 1. Then, the reinforcing plate 71 or the fixing plate 74 thereof is applied to the upright piece 41, and the bolt 48 is tightened with a nut on the back surface of the fixing plate 74 through the through hole 45, and when the side plate 7 comes to an appropriate position, it is attached. The bracket 3 and the side plate attaching bracket 4 are respectively fixed, and the side body 7 is fixed.
[0015]
Next, the upper end of the side plate 7 is brought inside the aster deck 10 when the side plate 7 is fixed, and the pushing screw 93 of the extrusion fitting 9 is screwed out via the reinforcing plate 76 of the side plate 7, The upper end of the side plate 7 is pressed and fixed to the outer deck 10. Thus, the upper and lower sides of the side plate 7 are fixedly supported. After the position of the side plate mounting bracket 4 is fixed, the long screw 61 and the bent piece 42 inserted into the through holes 47 of the bent piece 42 of the side plate mounting bracket 4 are fixed in position by nuts 62, 62, and the side plate is mounted. The support bracket 4 is also supported by the support plate 5.
[0016]
Subsequently, the side plate 7 is brought to the position adjacent to the fixed side plate 7, and the folded piece 72 of the reinforcing plate 71 of the side plate 7 to be fixed is slid on the folded piece 72 of the reinforcing plate 71 of the fixed side plate 7. And the outer ends 73 of the side plates 7 are overlapped. At the same time, the reinforcing plate 71 and the fixing plate 74 are applied to the folded pieces 41 of the bracket 4 for attaching the side plate, and the side plate 7 is fixed by the bolt 49. At this time, if necessary, the same operation as that of adjusting the position of the side plate attaching bracket 4 when attaching the side plate 7 is repeated. Of course, the adjustment this time is not as large as the adjustment of the side plate 7 attached before, and should be fine adjustment. As described above, the upper end of the side plate 7 is pressed and fixed to the outer deck 10 by the extrusion fitting 9.
[0017]
In this way, the side plate 7 and the side plate 7 are connected and fixed by one side plate mounting bracket 4, and the upper end and the lower end use one of the through holes 45, 46 of the upright piece 41, or The side plate 7 is fixed using the side mounting bracket 4 having the upright piece 41 having only one through hole. The bottom plate 8 has its outer end 84 placed on the lower bent edge 75 of the side plate 7, and is fixed by an L-shaped bracket 65 and screws 86, 86. Further, the center of the bottom plate 8 is suspended by being fixed to the mounting frame 53 or the mounting cover 54 attached to the support plate 5 by a long screw 87 provided on the reinforcing plate 81. Placement and fixation on the side plate 7 are the same as described above, but when the bottom plate 8 and the adjacent bottom plate 8 are joined with the reinforcing plates 81 at both ends, the folded pieces 82 are overlapped. In addition, the outer ends 83 of the bottom plate 8 are overlapped with each other to strengthen the joint between the bottom plates 8 and 8. Thus, the exterior of the escalator is formed by covering the outside of the escalator with the side plate 7 and the bottom plate 8.
