An H-shaped reinforcing material 702 is disposed inside the upper surface 703 and the outer surface 704 of the support arm 701, and the upper surface 703 of the support arm 701 and the upper surface 705 of the reinforcing member 702 are fixed by a plurality of bolts 708. A plurality of screw holes 709 pass through the lower surface 706 of the reinforcing member 702 at a position inside the connecting portion 707.

  As shown in FIG. 1, a support angle 72 having the same configuration as the support angle 70 is also provided at the rear end of the truss 12, that is, the end on the lower floor side.

  As shown in FIG. 1, the housings 2 and 2 are provided on the upper and lower floors of the building 1 in order to support the support angles 70 and 72 of the truss 12 of the escalator 10. The housing 2 is made of reinforcing steel or concrete, and as shown in FIGS. 2 and 3, is composed of a mounting surface 3, a front wall 4, a left wall 5, and a right wall 6 formed in a substantially horizontal state. The upper surface and the rear surface are open. The horizontal dimension of the mounting surface 3 is a rectangle formed to be slightly larger than the horizontal dimension of the support angles 70 and 72.

  As shown in FIGS. 3 and 4, a plurality of lower shims 74 are placed on the housing 2. The lower shim 74 is a rectangle that is slightly smaller than the mounting surface 3 of the housing 2, and a plurality of bolt holes 76 are opened along the left-right direction of the front end portion.

  As shown in FIGS. 4 and 5, an anchor plate 78 is placed on the lower shim 74. The anchor plate 78 is a rectangular plate that is slightly smaller in size than the mounting surface 3 of the housing 2, and is provided with bolts 82 that are screwed into the bolt holes 76 of the lower shim 74 along the left-right direction of the front end portion. Yes. A pair of left and right fixing members 80 are welded to the upper surface of the anchor plate 78. The fixing member 80 has a rectangular parallelepiped shape, and its longitudinal direction is arranged along the front-rear direction. The rear end portion of the fixing member 80 coincides with the position of the rear end portion of the anchor plate 78, and the front end portion is in the vicinity of the bolt 82. It extends to. When the fixing member 80 is welded to the anchor plate 78, it is welded in advance at the factory, not at the construction site where the escalator 10 is installed. As shown in FIG. 2, the attachment positions of the pair of left and right fixing members 80 and 80 are provided inside the pair of left and right support arms 701 and 701.

  As shown in FIG. 5, shim bases 84, 84 are disposed on the left and right sides of the anchor plate 78. As shown in FIG. 5, the shim base 84 has a rectangular planar shape, and the bolt holes 86 are opened along the front-rear direction.

  In a state where the support arm 701 is placed on the shim base 84, a space 98 (see FIGS. 10 and 11) between the shim base 84 and the fixing member 80 is shown in FIGS. As described above, an anti-swing member 92 is provided. The anti-sway member 92 has a rectangular planar shape and has a dish shape. As shown in FIGS. 6 and 12, a plurality of screw holes 94 are opened in the swing-preventing member 92 and can be screwed to the anchor plate 78 with screws 96.

(3) Method of Attaching Truss 12 A method of attaching the support angle 70 of the truss 12 to the housing 2 on the upper floor will be described in order with reference to FIGS.

(First step)
In the first step, as shown in FIG. 3, the operator places one or a plurality of rectangular plate-shaped lower shims 74 with bolt holes 76 opened on the placement surface 3 of the housing 2. . There are two purposes for placing the lower shim 74. The first purpose is to adjust the height of the support angle 70, and the second purpose is to adjust the placement surface 3 horizontally.

(Second step)
In the second step, as shown in FIG. 4, the operator places a plate-shaped anchor plate 78 on the plurality of lower shims 74. Then, the operator passes the bolt 82 through the bolt hole 76 and fixes the anchor plate 78 to the mounting surface 3 of the housing 2 with the shim 74 sandwiched therebetween.

(Third step)
In the third step, as shown in FIGS. 5, 7, and 8, the operator places shim bases 84, 84 on the left and right sides of the pair of left and right fixing members 80, 80 welded to the anchor plate 78. Further, a pair of left and right support arms 701 and 701 and reinforcing members 702 and 702 of the support angle 70 are disposed in a jacked up state. Similarly to the upper floor side, the lower floor support angle 72 is also arranged above the anchor plate 78 of the lower floor housing 2.

(4th process)
In the fourth step, as shown in FIGS. 6 and 9, the operator sequentially inserts shims 88 between the lower surface 706 of the reinforcing member 702 in the jacked up state and the shim base 84 to adjust the height. I do. In this case, as shown in FIG. 9, since the shim 88 can be inserted from the space 98 between the shim base 84 and the fixing member 80, the left wall 5 of the housing 2 becomes an obstacle as in the conventional case. There is no.

(5th process)
In the fifth step, when the height adjustment is finished, as shown in FIG. 10, the operator finishes jacking up and places the reinforcing member 702 horizontally on the shim 88.

(6th process)
In the sixth step, the operator screws the bolt 710 into the screw hole 709 of the reinforcing member 702, the screw hole 90 of the shim 88, and the screw hole 86 of the shim base 84 as shown in FIG. Then, the reinforcing member 702, the shim 88, and the shim base 84 are fixed.

(Seventh step)
In the seventh step, the operator arranges the swing prevention member 92 as shown in FIG. 12 in the space 98 between the shim base 84 and the fixing member 80 as shown in FIG. Secure to. Thereby, the attaching operation of the support angle 70 is completed.

  The member that fixes the swing prevention member 92 to the anchor plate 78 is not limited to the screw 96, but may be any member that receives shear such as a bolt or a pin.

(4) Effects According to the present embodiment, when the shim 88 is inserted between the jacked-up reinforcing member 702 and the shim base 84, the shim is removed from the space 98 between the shim base 84 and the fixing member 80. Since 88 can be inserted, that is, it can be inserted from the inside of the support arm 701, the left and right side walls 5 and 6 of the housing 2 do not become an obstacle as in the prior art.

  Further, since the anti-swing member 92 is provided between the shim base 84 and the fixing member 80, it is possible to prevent the support angle 70 from swinging in the lateral direction (left-right direction).

  Further, since the anti-sway member 92 and the fixing member 80 are arranged inside the pair of left and right support arms 701 and 701, the present embodiment can be realized with the housing 2 having the same size of the mounting surface 3 as the conventional one. Can do.

  Further, the support angles 70 and 72 of the truss 12 can be attached to the housing 2 of the building 1 without welding at the construction site of the escalator 10. Since the anchor plate 78 and the fixing member 80 are welded in advance at the factory, the operator does not need to perform welding at the site, is easy to perform, and is excellent in terms of environment.

  Further, when the anti-sway member 92 is screwed to the anchor plate 78 with the screw 96, the upper space is not covered with the support arm 701 and the reinforcing member 702, and thus can be easily screwed. .

(5) Modification Example In the above-described embodiment, the structure in which the building 2 is provided in the building 1 has been described. However, the present embodiment can also be applied to a receiving beam configured from a reinforcing bar.

  Moreover, in the said embodiment, although demonstrated applying to the escalator 10, you may replace with this and may apply to the moving sidewalk.

  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. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
