If the balustrade base 27 of the balustrade portion 33 is provided with an escape portion for allowing the head of the bolt 42 to escape, the bolt 42 can be screwed into the standing portion 25b in advance.

  By the way, when the frame body 21 is lifted by a lifting machine during the transportation or installation of the frame body 21, the frame body 21 is bent, and this bending causes an abnormal load on the balustrade portion 33, in particular, the balustrade panel 30. Fear arises.

  Therefore, in such a case, it is preferable to provide a tension member 45 between the balustrade bases 27 adjacent to each other, as shown in FIGS. 5 and 6 as the third embodiment.

  The tension member 45 includes a U-shaped connection tool 46 provided on the protrusion 39 of each balustrade base 27 adjacent to each other, a bolt shaft 47 connected to the connection tool 46, and one bolt shaft 47. And an adjustment nut 48 screwed over the end of the other bolt shaft 47, and by turning the adjustment nut 48, the distance between the two connecting devices 46 can be adjusted. ing. Each connecting tool 46 is provided with a set bolt 49 for fixing the connecting tool 46 to the projecting piece 39.

  When the frame body 21 is transported from the manufacturing plant to the site, the connecting tool 46 is attached to the projecting piece 39 of each balustrade base 27 that is lying down, and the adjusting nut 48 is turned to change the distance between the connecting tools 46. The connecting tool 46 is brought into close contact with the side edge of the projecting piece 39, and in this state, the fastening bolt 49 is tightened to fix each connecting tool 46 to the projecting piece 39.

  In this state, the frame body 21 is lifted by a lifting machine, loaded on a transport truck or the like and transported to the site, and the frame body 21 is lifted by the lifting machine and installed at a target location.

  When the frame body 21 is lifted by a lifting machine, the frame body 21 is bent, and this bending causes an abnormal load on the balustrade portion 33, in particular, the balustrade panel 30, which may cause deformation.

  However, if the tension member 45 is interposed between the protruding pieces 39 of the balustrade bases 27 adjacent to each other as described above, the bending of the frame body 21 is reduced, and the balustrade portion 33, particularly the balustrade panel 30 is deformed. Can be suppressed.

  In addition, after installing the frame body 21 at the target location, the tension member 45 is removed from between the projecting pieces 39, and the balustrade portion 33 is rotated upward about the hinge 28 and fixed.

  7 and 8 show a fourth embodiment. In this embodiment, the base member 24 provided on the upper surface of the beam member 22 at the upper side edge of the frame body 21 is attached to the frame member 21. A guide groove 51 extending in the width direction is formed.

  A guide projection 52 is formed on the lower surface of the horizontal portion 25 a of the support plate 25 that supports the balustrade portion 33, and the guide projection 52 is slidably fitted into the guide groove 51. A set bolt 54 is screwed from the horizontal portion 25 a of the support plate 25 to the base member 24. The set bolts 54 are screwed into the base member 24 through long holes 55 along the width direction of the frame body 21 formed in the horizontal portion 25a.

  In the case of this embodiment, by loosening the set bolt 54, the balustrade portion 33 together with the support plate 25 is slid along the guide groove 51 in the width direction of the frame body 21, and the set bolt 54 is tightened again. The support plate 25 and the balustrade part 33 can be fixed to the slide position.

  According to such a configuration, when the width dimension of the frame body 21 is small and the balustrade parts 33 provided on both sides of the frame body 21 are brought down inside, both the balustrade parts 33 interfere with each other. Even in such a case, the balustrade part 33 can be brought into a predetermined lying state by preventing the interference by sliding the balustrade part 33 toward the outer side of the frame body 21.

  9 and 10 show a fifth embodiment. In this embodiment, the balustrade panel 30 of the balustrade portion 33 is divided into a plurality of panel bodies 30a and 30b arranged in the longitudinal direction of the frame body. It is an example. When the balustrade panel 30 is made of glass, it is common to leave a gap of about 1 to 3 mm between the divided panel body 30a and the other panel body 30b.

  When the frame body is lifted by a lifting machine, the frame body is bent, and the bending may cause the panel bodies 30a and 30b to interfere with each other and break. Therefore, in this embodiment, a cushioning material 57 made of a material having elasticity such as rubber or urethane is provided in a gap between one panel body 30a and the other panel body 30b. The buffer material 57 has a structure that is simply sandwiched in the gap between the panel bodies 30a and 30b.

  According to such a configuration, the load when the frame body is lifted by the lifting machine and the frame body is bent and a load is applied to the panel bodies 30a and 30b is absorbed by the elastic deformation of the buffer material 57, and therefore An excessive load is not applied to the panel bodies 30a and 30b, and damage or the like can be prevented.

  FIG. 11 shows a sixth embodiment. In a frame body having a length that is not so long, even if the balustrade part is an integral one that is continuously connected, the weight is relatively light, so that it can be brought down and caused relatively easily.

  However, in passenger conveyors such as escalators with high floor height, the length of the frame body in the middle part becomes long, and an integral balustrade part that is continuously connected to the upper part of the side edge of the long frame body If it is provided, the weight of the balustrade part becomes considerably large, and it is difficult to bring down or cause it to fall.

  Therefore, in the fifth embodiment, the balustrade portion 33 is divided into a plurality of divided bodies 33a and 33b arranged in the longitudinal direction of the frame body, and the divided bodies 33a and 33b are supported via the rotation support mechanism 29. Each of the divided bodies 33a and 33b can be individually rotated and raised and lowered via the respective rotation support mechanisms 29.

  Therefore, in this case, each of the divided bodies 33a and 33b becomes relatively light, and the individual divided bodies 33a and 33b can be easily brought down or caused by a single worker, so that work efficiency and safety are improved. .

  The inner deck 31 and the handrail deck 35 in the balustrade portion 33 are divided into the respective divided bodies 33a and 33b. After the respective divided bodies 33a and 33b are raised and fixed, the inner deck 31 and the handrail deck 35 are separated. A separate piece of the inner deck 31a and the handrail deck 35a are attached to and connected to the blank space between the two parts to form a continuous structure. Although not shown, the outer deck is similarly divided into the respective divided bodies 33a and 33b, and after the respective divided bodies 33a and 33b of the balustrade section 33 are raised and fixed, in the blank space between the divisions of the outer deck. A separate piece of outer deck is attached and connected to form a continuous structure.

  Note that the present invention is not limited to the case where the escalator is a target, and can be similarly applied to a case where a passenger conveyor such as a moving sidewalk is a target.
