Description

  Embodiments described herein relate generally to a passenger conveyor and a method for attaching the passenger conveyor.

  When a passenger conveyor such as an escalator or a moving sidewalk is attached to a building, a building or a receiving beam is provided in the building, and a support angle of the truss of the passenger conveyor is bridged on the mounting surface of the building or the receiving beam.

  In the passenger conveyor as described above, the support angle on the lower floor side is a structure in which an anchor plate attached to the housing is fixed by a pin (generally referred to as a “shear pin”). Therefore, since the plate-like base into which this pin is inserted differs in the building to which the passenger conveyor is attached, the base is welded to the anchor plate in the field. However, the base welding work at the site is troublesome for the operator, and there is a problem that the work cannot be performed at a site where the use of fire is restricted.

  Therefore, in view of the above problems, an embodiment of the present invention proposes a passenger conveyor that can attach a pin to a base without welding on site and a method for attaching the passenger conveyor.

  Next, the lower floor side support angle 72 and the upper floor side support angle 70 will be described with reference to FIGS. 1 and 2. A support angle 72 is provided at the front end of the truss 12, that is, the end on the lower floor side. The support angle 72 includes a vertical plate 74 and a horizontal plate 76 that protrudes horizontally forward from the upper end of the vertical plate 74, and the horizontal plate 76 is mounted on the mounting surface 3 of the housing 2 as described later. The vertical plate 74 is fixed to the upper part of the front end portion of the truss 12.

  Further, a support angle 70 is provided at the rear end portion of the truss 12, that is, the end portion on the upper floor side. The support angle 70 is similarly composed of a vertical plate and a horizontal plate, and the vertical plate is fixed to the upper portion of the rear end portion of the truss 12, that is, the upper portion of the upper floor side end portion.

  The housing 2 is made of a reinforcing bar or concrete and is composed of a mounting surface 3 formed in a substantially horizontal state, and a front wall 4, a left wall 5, and a right wall 6 as shown in FIG. The rear surface is open.

  The horizontal plate 76 of the support angle 72 has a horizontal dimension that is slightly smaller than the horizontal dimension of the mounting surface 3 of the housing 2.

  A bush mounting hole 98 is opened at the center of the support angle 72. Four screw holes 100 are opened in the outer peripheral portion of the bush mounting hole 98. Bolt holes 104 into which jackup bolts 102 and 102 are screwed are opened on both sides of the support angle 72.

  Next, the anchor plate 78 on the lower floor side will be described with reference to FIGS. The anchor plate 78 is a rectangle having substantially the same shape as the placement surface 3. On both the left and right sides of the anchor plate 78, fasteners 80 are welded in advance in the front-rear direction. The stopper 80 has a plate-like position determining portion 80b erected from the outer end portion of the plate-like leg portion 80a. In the factory, the leg portions 80a of the pair of left and right fasteners 80 are welded in advance to the left and right side portions of the upper surface of the anchor plate 78. The distance between the pair of left and right fasteners 80 is set to a dimension 3 to 5 mm larger than the dimension of the support angle 72 in the left-right direction. Thereby, the support angle 72 placed between the pair of left and right stoppers 80, 80 does not move in the left-right direction.

  A mortar cover support member 84 for supporting the mortar cover is welded to the rear portion of the anchor plate 78 in the left-right direction in advance. The mortar cover is a cover for preventing the mortar from flowing to the support angle.

  A rectangular pin mounting base 86 is welded to the center of the anchor plate 78. A pin hole 90 is provided at the center of the pin mounting base 86 at substantially the same position as the bush mounting hole 98.

  As shown in FIG. 4, a pin 126 is inserted into the pin hole 90. The bushing 106 is arranged on the pin 126 from above. That is, the bush 106 is inserted into the bush mounting hole 98 and the upper portion of the pin 126 is accommodated in the shaft hole 108 of the bush 106. The upper tip portion of the pin 126 is sharpened to the extent that scribing is possible, as will be described in detail in a work process described later.

  Then, when the presser shim 112 is placed around the bush 106 protruding from the support angle 72, the presser plate 114 is placed on the upper surface of the bush 106, and the presser plate 114 is fixed with the screw 101, the pin 126 becomes the pin In a state where it is inserted into the pin hole 90 of the mounting hole base 86, it is fixed to the support angle 72 via the bush 106.

  Next, a process in which the worker attaches the support angle 72 of the truss 12 to the lower-side housing 2 will be described with reference to FIGS.

  As shown in FIG. 5, first, one or a plurality of rectangular plate-like lower shims 77 having bolt holes opened are placed on the placement surface 3 of the lower floor side casing. There are two purposes for placing the lower shim 77. The first purpose is to adjust the height of the support angle 72, and the second purpose is to place the placement surface 3 horizontally. Next, a plate-shaped anchor plate 78 is placed on the plurality of lower shims 77. Then, the operator fixes the anchor plate 78 to the mounting surface 3 of the housing with the plurality of lower shims 77 sandwiched therebetween. Thereafter, the pair of left and right height adjustment members are placed on the upper surface of the anchor plate 78 between the pair of left and right fasteners. Then, the pin mounting base 86 is fixed to the upper surface of the anchor plate 78. Thereafter, the horizontal plate of the support angle 72 of the truss is disposed above the pair of left and right fasteners and placed on the pair of left and right height adjustment plates. In this state, the operator checks whether the left and right direction of the support angle 72 is horizontal, and whether it is adjusted to the required height. If not, or if the height is not enough If not, the upper shim is sandwiched between the height adjustment plate and the horizontal plate. After adjusting the height of the support angle 72, the pin 126 is inserted into the pin hole 90 formed in the pin mounting base 86 using the bush mounting hole 98 of the support angle 72.

  After that, as shown in FIG. 6, a metal cylindrical bush member 106 ′ with no shaft hole formed therein is inserted into the bush mounting hole 98, and the bottom surface is pressed so as to contact the tip of the pin 126. Then, an indentation is made on the bottom surface of the bush member 106 ′. The tip of the pin 126 is a conical protrusion so that it can be marked.

  Then, as shown in FIG. 7, the bush member 106 ′ with the indentation is taken out from the bush mounting hole 98, and the bush member 106 ′ is excavated into a cylindrical shape around the indentation to form the shaft hole 108. create. In this excavation work, in the state shown in FIG. 5, the diameter of the pin 126 and the length of the pin 126 protruding from the pin mounting base 86 are measured in advance, and the diameter of the pin 126 and the protruding length of the pin 126 are determined. For reference, the bush member 106 ′ is excavated into a cylindrical shape so as to be accommodated in the protruding portion of the pin 126 from the pin mounting base 86, thereby creating the bush 106 in which the shaft hole 108 is formed. The length of the shaft hole 108 is the same as or longer than the protruding length of the pin 126 so that the bush 106 can be smoothly inserted into the protruding portion of the pin 126.

  As shown in FIG. 8, the created bush 106 is inserted into the bush mounting hole 98 and the pin 126 is accommodated in the shaft hole 108. As described above, since the shaft hole 108 is formed so that the pin 126 is accommodated around the indentation formed by the tip end portion of the pin 126, the mounting operation of the bush 106 to the pin 126 is smoothly performed. It can be carried out.

  9, after the bush 106 is accommodated in the bush mounting hole 98, as shown in FIG. 10, a predetermined number of donut-shaped presser shims 112 are stacked so as to be uniform with the upper surface of the bush 106. 4 is mounted and screwed to the support angle 72 with the screw 101, the completed state shown in FIG. 4 is obtained. Note that a screw hole may be formed in the holding plate 114, and a bolt may be screwed into the screw hole to fix the tip portion of the pin 126.

  Thus, the operator simply forms the shaft hole 108 corresponding to the pin 126 in the bushing material 106 'at the site, and the bushing material 106' corresponding to the site is formed, and the support angle 72 on the lower floor side is pinned. 126 can be fixed to the anchor plate 78.

  The upper floor support angle 70 is merely placed on the anchor plate 78 and is not fixed by the pin 126.

  According to this embodiment, the support angle 72 on the lower floor side of the truss 12 can be attached to the housing 2 of the building 1 without welding at the site where the escalator 10 is attached. Since the anchor plate 78 and the fastener 80 are welded in advance at the factory, the operator does not need to perform welding at the site, is easy to work, and is excellent in terms of environment.

  Although the above embodiment has been described with the configuration in which the building 1 is provided with the housing 2, the present embodiment can also be applied to a receiving beam composed of reinforcing bars.

  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.
