In the truss 1, a plurality of steps (not shown) that are connected endlessly and circulate in the truss 1 between the upper floor and the lower floor are accommodated. In the truss 1, a guide rail 5 for guiding a step that circulates is installed.

  A plurality of column bases 6, which are column connection portions, are attached to the upper surface portion of the truss upper chord member 2 along the longitudinal direction of the truss upper chord member 2. The column base 6 is attached to the truss upper chord member 2 by bolting. The column base 6 is attached to the truss upper chord member 2 in the factory where the truss 1 is manufactured before the truss 1 is shipped.

  A balustrade column 7 is rotatably connected to the column base 6. One end of the balustrade column 7 is rotatably connected to the column base 6, and a handrail deck 8 and a panel support 9 are fixed to the other end side of the balustrade column 7. A handrail rail (not shown) is connected to the handrail deck 8, and a handrail belt (not shown) that circulates and moves in synchronization with the steps is wound around the handrail rail. A plurality of support members 10 are attached to the panel support 9, and tips of these support members 10 are brought into contact with one side surface of the balustrade panel 11 attached to the upper portion of the truss 1, Prevent distortion.

  The pivot position of the balustrade pillar 7 connected to the pillar base 6 so as to be pivotable is that the balustrade pillar 7 stands up with respect to the truss 1 (see FIGS. 2 to 4 and 7) and the balustrade pillar 7 is A lying position (see FIGS. 1 and 6) that falls toward the inside of the truss 1 on the step side.

  As shown in FIG. 5, the column base 6 is formed in an L-shaped cross section including a first plate portion 6 a and a second plate portion 6 b.

  Four mounting holes 12a, 12b, 12c, and 12d are formed in the first plate portion 6a from the upper side to the lower side, and these mounting holes 11a to 11d are formed in a round hole shape or a long hole shape.

  The second plate portion 6b is attached with a support portion 13 that supports the lower portion of the balustrade pillar 7 rotated to the upright position. The support portion 13 is attached to the second plate portion 6b with bolts 14. Note that a mounting hole (not shown) through which the bolt 14 formed in the second plate portion 6b is inserted has a long hole shape in the vertical direction, and the mounting position of the support portion 13 is adjusted in the vertical direction. Is possible.

  As shown in FIG. 5, the balustrade pillar 7 is formed in an L-shaped cross section including a first plate portion 7a and a second plate portion 7b. When the balustrade pillar 7 is located in the upright position, the first plate portion 7 a faces the first plate portion 6 a of the column base 6 in parallel, and the second plate portion 7 b is the second plate portion of the column base 6. It is parallel to 6b.

  Two elongated hole-shaped attachment holes 15a and 15b and one arcuate hole 16 are formed in the first plate portion 7a. The arc-shaped hole 16 is formed in an arc shape centering on a fulcrum portion 17 that becomes a rotation center when the balustrade column 7 rotates with respect to the column base 6. The fulcrum portion 17 is a contact portion between the lower end portion of the second plate portion 7 b and the support portion 13. Moreover, the support part 13 functions also as a guide part which guides the balustrade pillar 7 which rotates, when the balustrade pillar 7 rotates between a standing position and a lying position.

  Two positioning bolts 18a and 18b, which are support portions, are attached to the second plate portion 7b. As shown in FIGS. 4 and 7, these positioning bolts 18 a and 18 b are arranged such that when the balustrade pillar 7 is rotated to the standing position, the bolt tip comes into contact with the surface of the second plate portion 6 b of the pillar base 6. It is provided so that it can be adjusted. Positioning of the balustrade pillar 7 rotated to the upright position in the truss width direction (direction perpendicular to the longitudinal direction of the upper truss member 2) by the tips of the positioning bolts 18a and 18b coming into contact with the surface of the second plate portion 6b And adjustment of the standing angle of the balustrade pillar 7 is performed.

  Here, a connection structure between the column base 6 and the balustrade column 7 will be described.

  FIG. 4 shows a state in which the balustrade pillar 7 is rotated to the upright position in the pre-shipment adjustment work performed before the truss 1 is shipped. The adjustment work before shipment means that the dimensions in the width direction, the height direction, and the traveling direction are temporarily assembled in the factory from the escalator standard so that the balustrade pillar 7 becomes the same as the field installation dimensions. In this temporarily assembled state, the bolt 19 is inserted into the mounting hole 15a of the balustrade column 7 and the mounting hole 12a of the column base 6 and tightened. Further, a bolt 20 as a support shaft member is inserted into the arc-shaped hole 16 of the balustrade pillar 7 and the mounting hole 12c of the pillar base 6 and tightened. Further, the front ends of the positioning bolts 18 a and 18 b are in contact with the surface of the second plate portion 6 b of the column base 6. Further, the lower end portion of the second plate portion 7 b of the balustrade pillar 7 is in contact with the surface of the support portion 13.

  As shown in FIG. 4, it is sufficient that the truss 1 temporarily assembled in the adjustment work before shipment can be shipped as it is. However, the truss 1 in the upright position is restricted by the height regulation of the transport vehicle and the restriction of the local carry-in route where the escalator is installed. The problem of interference with the rotating balustrade pillar 7 occurs.

  Therefore, when the truss 1 is transported, the balustrade pillar 7 is rotated to the lying down position as shown in FIG. 1 or FIG. By rotating the balustrade pillar 7 to the lying position, the outer dimensions of the truss 1 with the balustrade pillar 7 attached can be kept small, and in the process of transporting the truss 1 to the site where the escalator is installed, the balustrade pillar 7 Can be prevented from interfering with other members. When the balustrade pillar 7 is rotated from the standing position shown in FIG. 4 to the lying position shown in FIG. 6, the bolt 19 is removed and the bolt 20 is loosened. Then, the balustrade pillar 7 is rotated around the fulcrum portion 17 toward the lying position. With this rotation, the bolt 20 relatively moves in the arcuate hole 16. Further, the lower end portion of the second plate portion 7b moves while being in contact with the support portion 13 that is a guide portion.

  After the balustrade pillar 7 is rotated to the lying position shown in FIG. 6, the bolt 20 is fastened and fixed. The bolt 20, the arc-shaped hole 16, and the attachment hole 12 c function as a fixing mechanism that fixes the balustrade pillar 7 at the lying down position. The balustrade pillar 7 that has been rotated to the lying position is prevented from rattling due to vibration during conveyance by the surface of the second plate portion 7b being in contact with the support portion 13 and being fixed by a fixing mechanism. The bolt 19 is attached to the attachment hole 12a in order to prevent loss.

  FIG. 7 shows a state in which, after the truss 1 is transported to the site where the escalator is installed, the balustrade pillar 7 is rotated and fixed to the standing position. When the balustrade pillar 7 is rotated from the lying position shown in FIG. 6 to the standing position shown in FIG. 7, the bolt 19 is removed and the bolt 20 is loosened. Then, the balustrade pillar 7 is rotated around the fulcrum portion 17 toward the standing position. With this rotation, the bolt 20 relatively moves in the arcuate hole 16. Further, the lower end portion of the second plate portion 7b moves while being in contact with the support portion 13 that is a guide portion.

  After the balustrade pillar 7 is rotated to the standing position shown in FIG. 7, bolts 19 are inserted into the attachment holes 15 a of the balustrade pillar 7 and the attachment holes 12 a of the pillar base 6 and tightened. Further, the bolt 21 is inserted into the mounting hole 15b of the balustrade column 7 and the mounting hole 12b of the column base 6 and tightened. Further, the bolt 20 is once removed, and the bolt 20 is inserted into the arcuate hole 16 and the mounting hole 12d and tightened.

 When the balustrade pillar 7 is rotated to the standing position shown in FIG. 7, the tip ends of the positioning bolts 18 a and 18 b are brought into contact with the surface of the second plate part 6 b of the pillar base 6. Thereby, it is possible to reproduce the state in which the dimension in the width direction of the balustrade pillar 7 is temporarily assembled by the adjustment work before shipment, and the adjustment work on the field in the width direction of the balustrade pillar 7 becomes unnecessary. Further, the lower end portion of the second plate portion 7 b of the balustrade pillar 7 is brought into contact with the surface of the support portion 13. Thereby, it is possible to reproduce the state in which the dimension in the height direction of the balustrade pillar 7 is temporarily assembled in the adjustment work before shipment, and the adjustment work on the field in the height direction dimension of the balustrade pillar 7 becomes unnecessary.

  Moreover, in the said embodiment, the balustrade pillar 7 is substantially horizontal in the lying position, but since the width of the truss 1 is narrow, when the balustrade pillar 7 is fallen down horizontally, the balustrade pillar 7 that is positioned oppositely, etc. If there is a possibility of interference, one balustrade pillar 7 is not limited to being substantially horizontal, but may be supported at an arbitrary angle (not shown).

  In such a configuration, the balustrade pillar 7 is rotatably connected to the truss 1 in the factory, and is transported to the site where the escalator is installed while being rotated to the lying position, and is rotated to the standing position on the site. . For this reason, the operation | work of connecting the balustrade pillar 7 to the truss 1 in the field which installs an escalator becomes unnecessary, and the period which the installation operation of an escalator requires can be shortened.

  Furthermore, since the operation of rotating the balustrade pillar 7 to the standing position can be performed for each individual balustrade pillar 7, it is necessary to prepare many workers for the operation of rotating the balustrade pillar 7 to the standing position. It can be done by a small number of workers.

  Moreover, since the balustrade pillar 7 can be transported together with the truss 1 for the transportation to the site where the escalator is installed, there is no need to pack the balustrade pillar 7 separately or transport it separately. Can reduce the load.
