FIG. 6 and FIG. 6 are views of the escalator entrance / exit device of FIG.

  On both sides of the main frame 1 extending in the longitudinal direction, escalator entrance / exit devices 10 are provided. The escalator entrance / exit device 10 has a function to prevent the escalator entrance / exit device 10 from sliding and damaging the building part around the escalator entrance / exit device 10 when the escalator shakes. Yes.

In the escalator entrance / exit device 10, a building hole 12 having an opening A having an upper surface opened adjacent to the building floor 22 is provided. The opening A is covered with a floor plate 21.
A first edge plate 13a, a second edge plate 13b, and a third edge plate 13c are provided on each side wall surface 12a of the architectural hole 12. The first edge plate 13a is arranged on the side facing the step 3, and the second edge plate 13b and the third edge plate 13c are respectively movable handrails 4 from both ends of the first edge plate 13a. It extends in the same direction and is arranged on the side. The upper ends of the first edge plate 13 a, the second edge plate 13 b, and the third edge plate 13 c are fixed to the building floor 22 adjacent to the building hole 12.
A flat bearing plate 14 is fixed to the bottom surface of the architectural hole 12 by anchor bolts 15. At the corners on both sides of the bearing plate 14 on the side away from the step 3, support bodies 16 having a U-shaped cross section are disposed so as to cover the tip end portions of the anchor bolts 15. Both end surfaces of the support 16 abut against the surface of the bearing plate 14 and are fixed by welding.

A first engaging member 17 having an L-shaped cross section is in surface contact with a piece 16 a on the side of the building concrete portion 12 of the support 16 and is fixed by a bolt 18. The first engagement member 17 is provided with a second edge plate 13b in surface contact.
A groove 40 extending from the lower end surface is formed in the second edge plate 13b, and the second edge plate 13b is connected to the first engagement member 16 by a bolt 19 which is a fastening member penetrating the groove 40. Is engaged.
In addition, the 3rd edge board 13c is also being fixed to the building concrete part 12 via the 1st engaging member 17, the support body 16, and the bearing plate 14 by the structure similarly to the 2nd edge board 13b.

  As shown in FIG. 6, the first edge plate 13 a is also fixed to the architectural hole 12 via the bolt 24, the second engagement member 20, the support 16, and the bearing plate 14.

A floor plate 21 is fixed on the first engagement member 17 and the second engagement member 20.
A finishing material 23 is interposed between the side wall surface 12a of the building hole 12 and the edge plates 13a, 13b, and 13c in three directions excluding the step 3 side of the floor plate 21.

Next, a reference example of an entrance / exit device for an escalator will be described.
7 is a plan view showing an escalator entrance / exit device as a reference example of the present invention, FIG. 8 is a cross-sectional view taken along line VIII-VIII in FIG. 7, and FIG. 9 is IX-IX in FIG. It is arrow sectional drawing along the line.
In this reference example, the upper end portions of the first edge plate 13a, the second edge plate 13b, and the third edge plate 13c are fixed to the building floor portion 22 adjacent to the building hole 12, respectively.
The second edge plate 13b and the third edge plate 13c are provided with a support 33 having an L-shaped cross section using bolts 34 at the lower ends. The end of the support 33 is fixed to the upper surface of the building hole 12 facing the lower surface of the building floor 22 using anchor bolts 37.
The first edge 13a is connected to a support 33 having an L-shaped cross section via a first engagement member 35 and a second engagement member 36. The end of the support 33 is fixed to the upper surface of the building hole 12 facing the lower surface of the building floor 22 using anchor bolts 37.
In addition, the code | symbol 30 of FIG. 8 is a reinforcement body, the code | symbol 31 is a support body of the floor board 21, and the code | symbol 32 is a truss support part.

According to the escalator entrance / exit device 10 according to this embodiment, the upper end portion is fixed to the building floor portion 22 and the lower end portion is engaged with the engaging members 17 and 20 so as to be relatively slidable in the vertical direction. Edge plates 13a, 13b, and 13c are provided.
Therefore, as apparent from the comparison between the opening A of the first embodiment and the opening B partitioned by the side wall surface 12a of the architectural hole 12 shown in FIG. Form 1 has the effect of eliminating the need for the additional notch operation shown by the mesh pattern in FIG.

Further, the edge plates 13a, 13b, and 13c are formed with a groove portion 40 extending upward from the lower end surface, and the edge plate 40 and the engaging members 17 and 20 are fastening members that penetrate the groove portion 40. Since it is engaged with the bolt 19, the edge plate 40 and the engaging members 17, 20 can surely slide in the vertical direction together with the bolt 19 that moves along the groove 40.
The support 16 covers the end of the anchor bolt 15 and has a U-shaped cross section in which both end faces are fixed to the bearing plate 14. Therefore, both sides of the support 16 are open. It is easily fixed to the bearing plate 14 by welding work without interference with the anchor bolt 15.

In the above embodiment, the case of an escalator as a man conveyor has been described. Of course, the escalator is not limited to this, but may be a moving sidewalk, for example.
Further, instead of the anchor bolt 15, for example, a stat bolt may be used.
Furthermore, in the said embodiment, although the groove part 40 was formed in edge board 13a, 13b, 13c, a groove part is formed in an engagement member, and an engagement member and an edge board are used using the fastening member which penetrated this groove part. You may attach so that a relative sliding movement is possible.
