Description

  The present invention relates to passenger conveyor equipment such as an escalator in which a step board has a step or an electric road in which a step board does not have a step, and more particularly to a passenger conveyor equipment effective when an earthquake occurs.

  In the conventional passenger conveyor equipment, countermeasures such as those disclosed in Patent Document 1 are taken against the swinging of the building during an earthquake. That is, a sliding portion is provided between the passenger conveyor equipment and the floor so that the passenger conveyor equipment is not plastically deformed due to the displacement of the distance between the floors due to the swinging of the building during the earthquake.

JP 2001-158585 A

  The said patent document 1 is a countermeasure with respect to a passenger conveyor installation, and is a countermeasure on the assumption that the building structure in which the passenger conveyor installation was installed becomes an earthquake-resistant structure. Therefore, in the event of an earthquake, it would be meaningless to take measures to prevent plastic deformation of passenger conveyor equipment if the building structure is damaged.

  The objective of this invention is providing the passenger conveyor installation which can be installed which can improve the yield strength with respect to a building structure.

  In order to achieve the above-mentioned object, the present invention provides a passenger conveyor facility having a main body frame installed straddling between floors provided apart from each other, and a reinforcement for connecting the floors in the vicinity of the main body frame. He provided a body.

  In this way, by connecting the floors where passenger conveyor facilities are installed with reinforcements, it is possible to obtain a robust building structure in which the distance between floors is not displaced during an earthquake. Can prevent accidents in which passenger conveyor equipment installed with a large distance is dropped.

  As described above, according to the present invention, it is possible to obtain a passenger conveyor facility that can be installed so as to improve the proof stress on a building structure.

  Hereinafter, a passenger conveyor facility according to the present invention will be described based on the escalator shown in FIGS.

  The escalator 1 includes a main body frame 4 supported across an upper floor 2 and a lower floor 3 that are installed apart from each other at the top and bottom of the building structure, and is guided in the main body frame 4 and connected endlessly. A plurality of steps 5 that move, and a balustrade 6 that is erected along both sides of the rotation direction of these steps 5 are basically configured.

  Such an escalator 1 is installed in a building structure in such a manner that, on the upper floor 2 side, the upper side support beam 4A of the main body frame 4 is placed on the receiving beam portion 7A provided on the structure beam 7, and the lower floor 3 On the side, a lower support beam 4B of the main body frame 4 is placed and installed on a receiving beam portion 8A provided on the structural beam 8.

  In the present embodiment, a reinforcing body 9 made of, for example, H-shaped steel is arranged along the body frame 4 outside the escalator 1 in the relationship between the escalator 1 and the building structure installed as described above, and this reinforcing body. 9 is connected to the structural beams 7 and 8 of the upper floor 2 or the floor 3 via connecting tools 10A and 10B. The reinforcing bodies 9 are installed, for example, on both the left and right sides below the main body frame 4, and the reinforcing bodies 9 on both the left and right sides are connected to each other with a connecting girder 11 at a constant interval.

  By connecting the receiving beam portion 7A and the receiving beam portion 8A of the upper floor 2 and the lower floor 3 with the reinforcing body 9 as described above, the displacement in the horizontal direction X generated in the upper floor 2 at the time of an earthquake, for example. As a result, the expansion and contraction of the distance between the upper floor 2 and the lower floor 3 can be prevented, and the resistance of the building structure itself to rocking during an earthquake, in other words, Horizontal strength can be increased.

  Since the horizontal strength of the building structure is improved, the distance between the upper floor 2 and the lower floor 3 can be prevented from expanding and contracting. Therefore, the main body frame 4 of the escalator 1 by reducing the distance between the upper floor 2 and the lower floor 3. The plastic deformation in the compression direction can be prevented, and the upper side support beam 4A, the lower side support beam 4B, the receiving beam part 7A and the receiving beam of the main body frame 4 are extended by extension of the distance between the upper floor 2 and the lower floor 3. It is possible to avoid the worst situation that the engagement with the portion 8A is released and the main body frame 4 falls.

  By the way, in the said embodiment, although the said reinforcement body 9 is installed along the inclination of the main body frame 4 on the right-and-left outer side below the main body frame 4, as shown in FIG. It may be installed along the inclined direction on both sides directly below the main body frame 4, or may be installed side by side with the main body frame 4 or included in the main body frame 4 without departing from the spirit of the present invention.

  Further, in the present embodiment, no load is transferred between the main body frame 4 and the reinforcing body 9, but in a building structure where the distance between the upper floor 2 and the lower floor 3 is large, the reinforcing body By causing 9 to share the load of the main body frame 4, it is possible to prevent the escalator 1 from being bent due to its own weight.

  Further, in a building structure where the distance between the upper floor 2 and the lower floor 3 is large, the upper ends of the supports 11A and 11B are connected to an intermediate position of the reinforcing body 9, and the lower ends are structural beams of the lower floor 3. You may improve the earthquake resistance of a building structure where the distance between the upper floor 2 and the lower floor 3 is large so that it may fix to 12A, 12B. At that time, these supports 11A and 11B may be increased or decreased according to the length of the escalator installed, and the loads of the main body frame 4 of the escalator 1 may be shared by these supports 11A and 11B.

  Furthermore, since the reinforcing body 9 can be installed on the existing building structure when the escalator 1 is installed, it is not necessary to take special measures for improving the proof stress even if the building structure is modified, and the effect is great. is there.

  By the way, although the said embodiment demonstrated the escalator 1 as a passenger conveyor installation, it can be applied also to the electric road which does not produce a level | step difference in a tread, and in an electric road, it is not necessarily inclined over an upper floor and a lower floor. It is not limited to the type of electric road.
