BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a passenger conveyor such as an escalator or a moving walkway, and more particularly to improvement of the installation form of a main frame in a building or a civil engineering structure.

[0002]

2. Description of the Related Art Conventionally, as a structure for installing a main body frame of a passenger conveyor in a building structure, for example, a method for preventing a drop on the upper side of the main body frame disclosed in Japanese Utility Model Laid-Open No. 61-75483, and for example, an actual open system is used. There is known an installation form disclosed in Japanese Patent Publication No. 51-116591, in which the upper end and the lower end of the main body frame and three inclined portions are dispersedly supported.

[0003]

The former of the above-mentioned conventional examples is as follows.
We have taken measures to prevent the upper part of the main frame from falling off the building structure and falling in the event of a seismic motion or various vibrations, but there is no intention to reduce the civil engineering work cost for installing the passenger conveyor. It was Further, the latter has a problem that the construction or civil engineering work cost is high because the objects of the construction or civil engineering work are distributed to the upper and lower end portions and the three inclined portions as described above.

An object of the present invention is to provide a passenger conveyor which can significantly reduce the construction cost of a building or civil engineering structure associated with the installation of the passenger conveyor, while improving the overall earthquake resistance.

[0005]

In order to achieve the above object, the present invention provides a step which is endlessly connected and moves from a lower entrance / exit to an upper entrance / exit, and a handrail which moves in synchronization with the step. , A balustrade forming a travel path of this handrail, and an upper horizontal portion provided for supporting these structures and extending in the longitudinal direction of the structures,
A main body frame having an inclined portion and a lower horizontal portion, wherein an edge portion of an end portion of an upper horizontal portion of the main body frame is fixed to a building structure, and further, a part of the inclined portion of the main body frame. And the lower horizontal part are housed in a pit constructed in the shape of a U-shaped groove, while the bottom part of the end part of the lower horizontal part and a part of the bottom part of the inclined part are connected to the civil engineering work in the pit through a support. Supporting on the floor, two centralized supports on the upper and lower sides of the body frame
It is characterized in that it has a holding type installation form. Further, the bottom part of the lower horizontal part housed in the pit and the support part that supports a part of the bottom part of the inclined part slide in accordance with the positional displacement between the civil floor and the main body frame. It is characterized by having a sliding body.

The passenger conveyor of the present invention is installed in such a manner that the edge portion of the upper end portion of the main body frame is placed on the building structure,
The lower side of the main body frame is fixed and stored in a pit formed in a U-shaped groove in a building or civil engineering structure, while the lower horizontal portion of the lower end and the bottom of the inclined portion are respectively placed in the pit. Because it is configured to be supported by the civil engineering floor, the target of construction or civil engineering work to bear the load of the passenger conveyor is substantially two places in the upper side and the lower pit,
It is cheaper than the conventional one (3 places). Also, the upper side edge of the main body frame, with respect to the building structure on which it is mounted,
Since the passenger conveyor is fixed by a sufficient overlapping margin or a fixing method such as welding, which will be described later, even if the passenger conveyor encounters a large earthquake, for example, there is no concern that the passenger conveyor will be separated from the upper side where the position is high and fall. Further, the sliding body can follow the movement of the lower structure and the main body frame due to the vibration, so that the overall earthquake resistance can be achieved.
