A comb-like comb 60 is provided at the tip of the upper floor board 32, and a comb-like comb 62 is also provided at the lower board 34.

(2) Structure of Support Angles 2 and 3 Next, the support angles 2 and 3 will be described with reference to FIGS.

  The support angle 2 is fixed to the upper part of the short side surface on the upper floor side of the truss 12. The support angle 2 is formed of a horizontal plate 64 and a vertical plate 66 by bending a rectangular metal plate into a U shape. The vertical plate 66 is welded and fixed to the frame material on the upper side of the short side surface of the truss 12, and the horizontal plate 64 protrudes in the longitudinal direction of the truss 12. The escalator 10 can be installed in the building 1 by placing the horizontal plate 64 on the upper surface of the receiving beam 4 of the building 1.

  The support angle 3 on the lower floor side of the truss 12 has the same configuration and is placed on the receiving beam 4 of the building 1.

  By the way, the overlapping portion of the horizontal plate 64 that is placed on the receiving beam 4 is referred to as “barge allowance”. It is preventing. However, since it is necessary to extend the length of the allowance due to the strengthening of the seismic structure, in this embodiment, the extending member 68 is attached to extend the allowance for the support angles 2 and 3.

  The extending member 68 is formed by laminating and fixing a metal upper plate 70 and a lower plate 72, and the dimensions in the width direction of the upper plate 70 and the lower plate 72 are the same as the dimensions in the width direction of the support angle 2. This is the length, and the thickness of the support angle 2 and the thickness of the lower plate 72 are the same. Further, the length of the upper plate 70 in the longitudinal direction is determined by the length of the extending margin, and when it is desired to extend the margin by L1, as shown in FIG. And the horizontal plate 64 have a length L3 that is the sum of the lengths of L2.

  The lower plate 72 is fixed by welding to the lower surface of the upper plate 70, and is fixed to a portion of the upper plate 70 that does not overlap with the horizontal plate 64 in FIG. Therefore, the length of the lower plate 72 in the longitudinal direction is L1.

  As shown in FIG. 2, the end portion 76 of the upper plate 70 that overlaps the horizontal plate 64 is formed with a rectangular cutout portion 74 and is formed in an uneven shape.

  When fixing the extending member 68 to the support angle 2, as shown in FIG. 2, the operator puts the upper plate 70 on the horizontal plate 64 from above the support angle 2 placed on the receiving beam 4, The lower plate 72 is placed on the receiving beam 4. Then, the operator welds the horizontal plate 64 and the upper plate 70 along the uneven end portion 76. As a result, the allowance for the support angle 2 is increased by L <b> 1 by the extending member 68.

  The extension member 68 is similarly attached to the support angle 3 on the lower floor side.

(3) Effect According to the present embodiment, it is possible to extend the cost by simply fixing the extending member 68 to the support angle 2 that is already placed on the receiving beam 4 of the building 1, and the earthquake resistant structure Can be strengthened.

  When the extending member 68 is attached to the upper plate 70 of the support angle 2, it is only necessary to weld the upper plate 70 to the horizontal plate 64 from above, and the operation can be easily performed. Cost can be reduced.

  Moreover, since the edge part 76 of the upper board 70 of the extending member 68 is formed in uneven | corrugated shape, a welding location becomes long and can be fixed more firmly.

(4) Modification 1
Modification 1 will be described. In the above-described embodiment, the end portion 76 of the upper plate 70 of the extending member 68 is formed in a concavo-convex shape. However, the present invention is not limited thereto, and the end portion 76 may be formed in a linear shape and welding may be performed along the linear shape.

(5) Modification 2
Modification 2 will be described with reference to FIGS. The difference between the modified example 2 and the above embodiment is that the end portion 76 of the upper plate 70 of the support angle 2 is linear, and the upper plate 70 and the horizontal plate 64 are fixed by a plurality of bolts 78 instead of welding. There is in point.

  Thus, even if the extending member 68 is fixed to the support angle 2 with a plurality of bolts 78, the length of the support angle can be easily extended.

  In addition, since the extending member 68 is also fastened only by a plurality of bolts 78, the operation is easy.

(6) Others In the above-described embodiment, the description has been made by adapting to the step 30 of the escalator 10, but it may be adapted to a step (step) of a moving sidewalk instead.

  Although one embodiment of the present invention has been described above, this embodiment is presented as an example and is not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention.
