If only the width direction displacement restricting portion 11 is fixed to the upper surface of the base member 10 by welding or the like from the preparation step, a step of placing the base member on the upper surface of the building support beam (step S21) is executed. Before, at the installation site of the passenger conveyor, the longitudinal displacement restricting portion 12 is fixed to the upper surface of the base member 10 by welding or the like, the height adjusting bolt hole 13 is formed on the upper surface of the base member 10, and the base member 10 What is necessary is just to form the hole 14 for an architectural fixing. That is, a process other than the process performed in the above-described preparation process may be performed at the installation site of the passenger conveyor before the process of placing the base member on the upper surface of the building receiving beam (step S21). .

As described above, according to the present embodiment, it is possible to provide a passenger conveyor installation method capable of improving workability without requiring any special work on the building frame.
Further, according to the present embodiment, in the installation work of the passenger conveyor, the step of fixing the width direction displacement restricting portion on the upper surface of the base member shown in the preparation step (step S11), the longitudinal direction on the upper surface of the base member By performing at least one of the step of fixing the direction displacement restricting portion (step S12) and the step of forming the bolt hole for adjusting the height of the base member (step S13) in advance in a factory or the like, the narrow portion Work can be reduced, and the installation workability of the passenger conveyor can be improved.
In addition, although the present Example demonstrated as an example the case where the lower surface of the horizontal surface of the truss support angle 3 as an example of a passenger conveyor support part was fixed to the upper surface of the base member 10 fixed to the building receiving beam 4a, It is not limited to. For example, it is good also as a structure which mounts on the upper surface of the base member 10, without fixing the lower surface of the horizontal surface of the truss support angle 3 as an example of a passenger conveyor support part, and the truss support angle 3 can slide (slid). .

  In addition, according to the present embodiment, the fixing part has a bolt fastening structure, so that welding work involving fire is not required at the installation site of the passenger conveyor, the quality control can be simplified, and the welding qualification can be achieved. Even an operator who does not have it can perform the installation work of the passenger conveyor.

  Furthermore, according to this embodiment, when the bolt fastening structure is adopted, the size of the hole is made larger than the diameter of the bolt, that is, by using an oblong hole in the width direction or the vertical direction, the adjustment margin in the positioning operation is increased. However, if the dimensions of the oblong hole are less than the allowable design tolerance, it will be impossible to perform installation work against the design intentions at the installation site. Work quality control can be simplified.

  In addition, although the present Example described about the local construction work of the truss support angle 3 and the building receiving beam 4a, it can apply similarly to the local construction work which fixes the intermediate support pillar etc. which are not shown in figure and a passenger conveyor.

  In addition, this invention is not limited to an above-described Example, Various modifications are included. For example, the above-described embodiments have been described in detail for easy understanding of the present invention, and are not necessarily limited to those having all the configurations described.
