  An upper floor support angle 28 is provided at the end of the upper floor horizontal truss 14, and is placed on the upper floor support 2 via a plurality of adjustment plates 40 for adjusting the height. ing. The support angle 28 on the upper floor side will be described in detail later.

  A support angle 30 on the lower floor side is provided at the end of the horizontal truss 18 on the lower floor side, and is placed on the receiving base 3 on the lower floor side via a plurality of adjustment plates 32 that adjust the height. It is fixed by welding to the cradle 3 on the lower floor side. In addition, a positioning plate 34 bent in an L-shape is provided on the receiving floor 3 on the lower floor side in order to position the support angle 30 on the lower floor side.

(2) Upper floor support angle 28
Next, the support angle 28 on the upper floor side will be described with reference to FIGS.

  The support angle 28 on the upper floor side is composed of a mounting plate 36 in a horizontal state and a fixing plate 38 bent downward from the mounting plate 36, and the fixing plate 38 is a horizontal truss 14 on the upper floor side. It is fixed to the end of the bolt with bolts. The mounting plate 36 is mounted on the upper-stage cradle 2 via a plurality of adjusting plates 40 that adjust the height. However, this mounting plate 36 is not fixed with respect to the cradle 2 and is placed so as to overlap the cradle 3 by the length of the hook margin L stipulated in the enforcement guideline of the elevator seismic design. Yes.

  As shown in FIG. 4, the mounting plate 36 has a plurality of measurement holes 42. The plurality of measurement holes 42 are provided at predetermined intervals along the front-rear direction of the truss 12 and are shifted in the left-right direction every one or more. The measurement hole 42 is a round hole, and is set to a size so that the upper surface of the cradle 2 can be seen inside when an operator looks into it from above, as shown in FIG. That is, the plurality of measurement holes 42 are not provided in a straight line along the front-rear direction of the truss 12 but are provided with variations in the left-right direction. This is to maintain the strength of the support angle 28. A position where the plurality of measurement holes 42 penetrate the mounting plate 36 of the support angle 28 is provided at a position other than the adjustment plate 40.

  As shown in FIG. 4, a scale 50 is provided along the plurality of measurement holes 42 provided in the front-rear direction. The scale 50 is used as a reference for confirming the position of the cradle 2.

  On the upper surface of the cradle 2 on which the support angle 28 is placed, a phosphorescent paint that emits light by itself when it is exposed to light is applied.

  As shown in FIG. 3, a detachable cover 44 is provided above the upper floor side mounting plate 36, and the board 46 for the escalator 10 and the floor 48 on the upper floor are on the same plane. It is configured as follows.

(3) Checking method for L of the support angle 28 on the upper floor side When the escalator 10 is newly installed, or after a large earthquake occurs, check the cost L of the support angle 28 on the upper floor side. The inspection method will be described.

  First, the operator removes the cover 44 shown in FIG.

  Next, as shown in FIG. 2, the operator looks into the mounting plate 36 of the support angle 28 on the upper floor side from above and emits light with a flashlight into the plurality of measurement holes 42 opened in the mounting plate 36. Hit it. When the light hits, the phosphorescent paint applied to the cradle 2 on the upper floor emits light, and the end of the cradle 2 can be confirmed from above as shown in FIG. Then, the operator compares the position of the end of the cradle 2 viewed from the side scale 50 and the measurement hole 42 to check whether the allowance L is a specified length. To do.

  Next, when the worker satisfies the length defined by the start allowance L, the worker puts on the cover 44 again and continues using the escalator 10.

(4) Effect With the escalator 10 according to the present embodiment as described above, it is possible to confirm whether or not the defined allowance L is satisfied when the operator looks into the measurement hole 42. Further, since the scale 50 is provided, the cost L can be measured more accurately.

  In addition, since the mortar is not applied to the mounting plate 36 of the support angle 28 to form a floor as in the prior art, but the cover 44 is only covered, the cover 44 is simply removed. The cost L can be checked.

  In addition, since the phosphorescent paint is applied to the upper surface of the cradle 2, the inside of the measurement hole 42 can be easily confirmed even when the dark portion is looked into from the bright portion. That is, it can be determined that the cradle 2 is present when the light of the phosphorescent paint is visible, and that the cradle 2 is not present under the measurement hole 42 when the light is not visible.

  Further, since the plurality of measurement holes 42 are not provided on a straight line, the strength of the support angle 28 can be maintained.

(5) Modification Example Next, a modification example of the above embodiment will be described.

  In the above embodiment, the measurement hole 42 is a round hole, but is not limited thereto, and may be a long hole, an elliptical hole, or a square hole.

  In the above embodiment, the scale 50 is provided, but the scale 50 may not be provided, and the length of the margin L may be determined based on the position of the measurement hole 42 where the end of the cradle 2 can be seen.

  Further, in the above-described embodiment, the plurality of measurement holes 42 are opened at a ratio of 2, 2, 2, and 1. However, the number is not limited to this number as long as the measurement holes 42 are not limited to this and are shifted in the left-right direction. .

  Moreover, in the said embodiment, although the upper floor side was non-fixed and the lower floor side was fixed, on the contrary, the upper floor side may be fixed and the lower floor side may be unfixed. In this case, the measurement hole 42 is provided in the support angle 30 on the lower floor side.
