Description

  The present invention relates to a balustrade panel mounting device for a man conveyor such as an escalator and a moving sidewalk, and a positioning jig therefor.

  As is well-known, man conveyors such as escalators and moving walkways are trusses, endlessly arranged, a large number of steps that circulate in the truss, and a pair of left and right guide rails that guide these steps in the direction of movement. And a pair of left and right balustrades erected on both sides in the moving direction of the step, and a pair of left and right endless handrail belts that are attached to the periphery of each balustrade and move in synchronization with the step.

  The balustrade includes a balustrade panel made of glass or the like, a deck that is provided at the upper end of the balustrade and supports a handrail belt, and a skirt that protects the feet of passengers.

  When renewing or refurbishing the man conveyor, it is necessary to change and replace parts related to the design of the man conveyor, such as balustrade panels, decks, and handrail belts, leaving guide rails. A panel receiver is detachably attached to the hole formed in the hole through a bolt, and the lower end of the balustrade panel is received and supported by this panel receiver.

  Conventionally, the panel receiver has been attached as follows. In other words, a downward swing is hung from the center line stretched between a pair of center poles erected on both ends of the truss, and the panel receiver is positioned and adjusted one by one from the center line. It was fixed with bolts while supporting it so that it would not slip off.

  In such a method, it is necessary to install the panel receiver while adjusting the position by swinging down one by one, so it takes a lot of work, and if the height between the floors is large and the number of panel receivers is large, It takes more time to install the panel holder, which affects the construction period.

  Further, in such a method, the position of the panel receiver is slightly shifted, and when the balustrade panel is attached, a step is generated between the panels, and an unnecessary force may act on the panel.

  In addition, because the panel holders are attached to the truss with a pre-set hole pitch, the balustrade panel must be assigned with the hole pitch, making it difficult to reflect customer requests, In this case, the standard panel cannot be used, so the cost is high.

  In addition, when changing the pitch, the truss must be drilled one by one with an electric drill or hydraulic puncher so that the panel receiver can be attached to other positions. It is necessary to fix with about 4 points using a large size bolt, and even when drilling a hole in the truss, a large hole cannot be drilled at one time. It is necessary to perform drilling in about three stages to open the circle, which requires a huge amount of time and a large number of workers.

  In addition, if the hole position is shifted, an additional work for drilling or expanding the hole is added, which requires great effort and time.

  In addition, since the strength of the truss may be affected by processing the truss, the portion that can be processed may be limited.

In order to solve the above problems, according to the present invention,
A panel receiving base placed on the truss of the man conveyor,
A plurality of panel receivers mounted on the panel receiver base and receiving and supporting the lower end of the balustrade panel of the man conveyor,
