JP 2001-158585 A

  The technique disclosed in Patent Document 1 is a countermeasure against the passenger conveyor device, and is based on the premise that the building in which the passenger conveyor device is installed has an earthquake-resistant structure. Therefore, even if measures are taken against the fall of the passenger conveyor device during an earthquake, it is meaningless if the building is damaged by shaking.

  The objective of this invention is providing the passenger conveyor apparatus for building earthquake resistance which can improve the earthquake resistance with respect to a building.

  In order to achieve the above object, according to the present invention, the upper part of the frame of the passenger conveyor is fixed to a strength member provided in the building via a connecting means.

  As explained above, by fixing the upper part of the frame of the passenger conveyor to the building, it can be suppressed until the passenger conveyor is damaged against the shaking during the earthquake of the building, and as a result, the building It is possible to obtain a passenger conveyor device for building earthquake resistance that can improve the earthquake resistance of the building.

  A first embodiment of a passenger conveyor device for building earthquake resistance according to the present invention will be described below with reference to an escalator device shown in FIGS. The escalator device 1 shown here is installed across a platform (ground) 2 of a station building and a bridge passage (building) 4 supported from the platform 2 via a support 3.

  And the escalator apparatus 1 has installed the frame 5 across the floor surface 2F of the platform 2 which is the ground, and the floor surface 4F of the bridge passage 4 which is a building.

  As shown in FIG. 3, the frame body 5 includes a pair of left and right side frames 6A and 6B, and a connecting beam 7 that connects the side frames 6A and 6B. The side frames 6A and 6B include upper chord members 8A and 8B extending in the longitudinal direction, lower chord members 9A and 9B disposed below the upper chord members 8A and 8B, and the upper chord members 8A and 8B. 8B and lower chord members 9A and 9B are provided with connecting members 10A and 10B.

  As shown in FIG. 2, the frame 5 configured in this manner includes an inclined section L1, an upper horizontal section L2 that is continuous with the upper portion of the inclined section L1, and a lower horizontal section L3 that is continuous with the lower portion of the inclined section L1. Have.

  The lower horizontal section L3 of the frame body 5 thus configured is housed in the pit 2P provided in the home 2, and its end is engaged in the vicinity of the floor surface 2F, and the end of the upper horizontal section L2 Is engaged in the vicinity of the floor surface 4F of the bridge passage 4. In such a frame body 5, a plurality of step plates 11 connected endlessly are guided so as to be rotated by a driving means (not shown). A balustrade panel 12 is erected on each of the side frames 6A and 6B along both sides of the tread board 11, and a moving handrail 13 driven in synchronization with the tread board 11 is guided along the periphery of the balustrade panel 12. Has been.

  Further, the upper bent portion P1 between the inclined section L1 and the upper horizontal section L2 of the frame body 5 and the lower bent section P2 between the inclined section L1 and the lower horizontal section L3 are applied to compressive force and tensile force. Therefore, the upper reinforcing plates 14A and 14B are provided from the upper horizontal section L2 to the part of the inclined section L1 through the upper bent section P1, and the inclined section from the lower horizontal section L3 through the lower bent section P2. Lower reinforcing plates 15A and 15B are provided over part of L1.

  The upper reinforcing plates 14A, 14B and the lower reinforcing plates 15A, 15B are within the width dimension W so as not to interfere with the installation of the components of the escalator device 1 beyond the width dimension W of the side frames 6A, 6B. In order to be positioned, plate materials having substantially the same thickness as the upper chord members 8A and 8B and the lower chord members 9A and 9B are used. The upper reinforcing plates 14A and 14B and the lower reinforcing plates 15A and 15B extend in the height direction and are connected by welding over the lower edges of the upper chord members 8A and 8B and the upper edges of the lower chord members 9A and 9B. In addition, it is connected to the connecting members 10A and 10B by welding as necessary.

  As shown in FIG. 1, the upper part of the frame body 5 configured in this way, specifically, the upper part of the inclined section L1 of the frame body 5 is connected to the support body 3 of the bridge passage 4 as a strength member. It connects via the wire rope 16 which is a means. Specifically, a connecting seat 17 is fixed to the upper part of the pair of left and right lower chord members 9A, 9B in the inclined section L1 of the frame body 5, and eyebolts 18A, 18B are connected to the connecting seat 7 and the support body 3, respectively. The tension is applied through the wire rope 16 between the eyebolts 18A and 18B. In place of the wire rope 16, a chain or a connecting rod may be used.

  As described above, by connecting the upper part of the frame 5 of the escalator device 1 to the support 3, even if the bridge passage 4 is swayed during an earthquake, the sway of the escalator device 1 connected by the wire rope 16 is generated. The frame 5 becomes a strength member and is suppressed. As a result, the earthquake resistance of the bridge passage 4 is improved.

  However, in the case of an earthquake with a low seismic intensity or a building with a seismic structure (bridge passage 4), the frame 5 of the escalator device 1 is not reinforced by the upper reinforcing plates 14A and 14B and the lower reinforcing plates 15A and 15B. However, although it can withstand to some extent, a large force acts on the frame body 5 of the escalator device 1 and tries to deform the frame body 5 by suppressing the shaking of the bridge passage 4 during an earthquake with a large seismic intensity. In that case, the upper bending portion P1 and the lower bending portion P2 of the frame body 5 where the compressive force and the tensile force are easily concentrated are reinforced by the upper reinforcing plates 14A and 14B and the lower reinforcing plates 15A and 15B. Since seismic strength can be imparted to the body 5 itself, shaking of the bridge passage 4 can be easily suppressed.

  Thus, even if the bridge passage 4 is about to roll due to an earthquake, the frame body 5 of the escalator device 1 reinforced against compressive force or tensile force can prevent the roll, and the bridge passage 4 is earthquake resistant. Can be improved. In other words, since the escalator device 1 improves the earthquake resistance of the bridge passage 4, the support body 3 of the bridge passage 4 may be designed with emphasis on the vertical load, and therefore the design and construction of the support body 3 can be simplified. It becomes possible to.

  Further, by fixing the upper part of the inclined section L1 of the frame 5 to the support 3 of the bridge passage 4 that is a building, a tensile force acting in the longitudinal direction of the frame 5 can be applied to the upper bent portion P1. In some cases, the mechanical strength of the upper reinforcing plates 14A and 14B can be lowered or omitted.

  FIGS. 5 and 6 show a first modification of the frame 5, and the same reference numerals as those shown in FIGS. 1 to 4 indicate the same components, and thus detailed description thereof will not be repeated.

  In this modification, the configuration different from that of the first embodiment is that portions other than those reinforced by the upper reinforcing plates 14A and 14B and the lower reinforcing plates 15A and 15B in the inclined sections L1 of the side frames 6A and 6B are further provided. Reinforce and improve the earthquake resistance of the building.

  That is, in the side frames 6A and 6B of the inclined section L1 other than those reinforced by the upper reinforcing plates 14A and 14B and the lower reinforcing plates 15A and 15B, the lower and upper edges of the upper chord members 8A and 8B and the lower chord members 9A and 9B. In addition, the upper edge side intermediate reinforcing plates 19A and 19B and the lower edge side intermediate reinforcing plates 20A and 20B are connected in the same manner as in the first embodiment.

  Thus, by connecting the upper edge side intermediate reinforcing plates 19A and 19B and the lower edge side intermediate reinforcing plates 20A and 20B to the lower and upper edges of the upper chord members 8A and 8B and the lower chord members 9A and 9B, the upper chord member 8A, As a result, the cross-sectional areas of 8B and the lower chord members 9A and 9B are increased. As a result, the strength of the upper chord members 8A and 8B and the lower chord members 9A and 9B in the inclined section L1 can be improved, and a frame 5 that is strong against compressive force and tensile force can be obtained. ) Can be further improved.

  FIG. 7 shows a second modification of the frame 5 that is a further modification of FIGS. 5 and 6. The same reference numerals as those shown in FIGS. 1 to 6 indicate the same components. Description is omitted.

  In the second modification, as a configuration for further improving the strength against the compressive force of the upper bent portion P1 of the frame body 5, the lower chord members 9A and 9B and the inclined section L1 in the upper horizontal section L2 are provided inside the upper bent section P1. A reinforcing beam 21 is provided across the lower chord members 9A and 9B in FIG. 2 and the space between the reinforcing beam 21 and the lower chord members 9A and 9B is closed with an auxiliary reinforcing plate 22 or the upper reinforcing plates 14A and 14B are extended to the reinforcing beam 22. It extends so as to close the space between the reinforcing beam 22 and the lower chord members 9A and 9B.

  Thus, by providing the reinforcing beam 22, even if the compression force acts on the frame 5 and the upper bent portion P1 is bent inward, the reinforcing beam 22, the auxiliary reinforcing plate 22, and the upper reinforcing plates 14A and 14B. Therefore, the bending can be counteracted, and as a result, the shaking of the building can be suppressed.
