  Here, in the passenger conveyor device configured as in Patent Document 1, the inter-beam dimension between the upper-floor side building-side receiving beam and the lower-floor side building-side receiving beam is short due to interlayer deformation. In order to prevent the main body frame from being damaged due to the compressive force acting on the main body frame, a gap having a dimension longer than the assumed interlayer deformation is provided between the main body frame and the building side receiving beam. Yes. Also, assuming that the gap between the beams becomes longer due to inter-layer deformation due to securing such a gap having a relatively long dimension, the allowance of the support angle to the building-side receiving beam is sufficiently long. It is necessary to make the dimensions.

  However, in order to install a passenger conveyor device having an earthquake-resistant structure as described in Patent Document 1, there is a gap between beams between a building-side receiving beam on the upper floor side and a building-side receiving beam on the lower floor side. It is essential to set the dimension to a predetermined value. That is, since a gap having a dimension longer than the assumed amount of interlayer deformation is provided between the main body frame and the building-side receiving beam, it is necessary to set the dimension between the beams longer. However, if it is a new building structure, there is no problem. However, in the case of an existing building structure, the inability to change the beam-to-beam dimension becomes an obstacle, and the above-mentioned earthquake-resistant structure is provided when renewing the passenger conveyor device. There was a problem that it could not be installed.

  The present invention has been made from the above-described prior art, and the object thereof is to prevent the body frame from dropping due to interlayer deformation without requiring the change of the inter-beam dimension of the building structure. It is to provide a passenger conveyor device.

In order to achieve the above object, the present invention provides an upper horizontal part that is constructed between an upper floor and a lower floor of a building structure, and that is connected to the upper floor, and a lower horizontal part that is connected to the lower floor. And a main body frame having an inclined portion formed between the upper horizontal portion and the lower horizontal portion, and provided at both end portions of the main body frame, and supported by a building-side receiving beam of the building structure. The main body frame is provided with at least one of the upper horizontal portion and the lower horizontal portion to be lower in rigidity than other regions of the main body frame, and the main body frame. A compression region that can be compressed preferentially over other regions of the main body frame by a compressive force acting in the longitudinal direction of the main frame material, and the compression region is a main chord material that extends in the horizontal direction constituting the main body frame. It is characterized that you are formed by having a notch.

  According to the present invention, when an excessive compressive force is applied to the main body frame due to the interlayer deformation, the compressive area provided in the upper or lower horizontal portion is positively compressed to absorb the compressive force. It is possible to prevent other regions from being deformed, and thereby prevent the main body frame from being deformed at an unexpected location other than the horizontal portion where the influence of the deformation is small, thereby preventing the breakdown of the device or the main body frame from dropping. In addition, even if the overall length of the main frame is shortened due to compression, the extension of the main frame receiving beam secures the allowance for the building receiving beam and the main frame falls. Can be prevented. Therefore, when renewing a passenger conveyor device for an existing building structure, the gap between the beams of the building structure cannot be changed, so that a sufficiently long gap is provided between the main body frame and the building-side receiving beam. Even if it cannot be provided and the risk of compression of the main body frame increases, the main body frame can be prevented from dropping due to compression.

It is a side view of the upper horizontal part which shows one Example of the passenger conveyor apparatus which concerns on this invention. It is a longitudinal cross-sectional view which follows the AA line of FIG. It is a longitudinal cross-sectional view which follows the BB line of FIG. It is a side view of the upper horizontal part which shows the state which the compression area | region compressed.

  Embodiments of the present invention will be described with reference to the drawings. In the drawings, the same or similar components are denoted by the same reference numerals and description thereof is omitted.

  The passenger conveyor apparatus 1 of the present embodiment is, for example, renewed and installed in an existing building structure, and is constructed between the upper floor 2 and the lower floor 3 of the building structure, and the upper floor 2 A main body frame 4 having an upper horizontal portion 4a continuous to the lower floor 3, a lower horizontal portion 4b continuous to the lower floor 3, and an inclined portion 4c formed between the upper horizontal portion 4a and the lower horizontal portion 4b.

  The main body frame 4 includes a pair of left and right upper chord members 5 and lower chord members 6, a plurality of vertical members 7 that connect these members, and a cross member 8 that connects the vertical members 7 that are paired left and right. . The upper chord member 5 and the lower chord member 6 function as main chord members extending in the longitudinal direction of the main body frame 4.

  A body frame-side receiving beam 9 such as a support angle is provided at the terminal end of the upper horizontal portion 4a, and a building-side receiving beam 10 that supports the body frame-side receiving beam 9 is formed on the upper floor 2. Yes. The main body frame side receiving beam 9 is fixed to the building side receiving beam 10 and constitutes a fixed portion A.

  A body frame side receiving beam 11 such as a support angle is provided at the terminal end of the lower horizontal portion 4b, and a building side receiving beam 12 that supports the body frame side receiving beam 11 is formed on the lower floor 3. Yes. Although not described in detail, the main body frame side receiving beam 11 is placed on the building side receiving beam 12 so as to be relatively movable, and constitutes a non-fixed portion B. That is, when an interlayer displacement due to interlayer deformation occurs between the upper floor 2 and the lower floor 3 due to an earthquake or the like and an external force is applied in the longitudinal direction of the main body frame 4, the main body frame 4 is elongated through a sliding structure (not shown). By moving in the direction, a large compressive force is prevented from acting in the longitudinal direction of the main body frame 4.

  And the passenger conveyor apparatus 1 of a present Example is devised in order to prevent that the main body frame 4 falls by interlayer deformation, without changing the dimension between beams of a building structure. Specifically, as shown in FIG. 2, the upper horizontal portion 4 a has a lower rigidity than other regions of the main body frame 4, and the other regions of the main body frame 4 are compressed by a compressive force acting in the longitudinal direction of the main body frame 4. A compression region 13 that can be compressed more preferentially is provided, and an extension member 14 that extends a contact amount with the building side receiving beam 10 is provided on the main body frame side receiving beam 9. The extension member 14 is extended beyond the cost before renewal. The compression region 13 is provided with a notch 15 in the upper chord member 5 which is a main chord member extending in the horizontal direction constituting the main body frame 4, and thereby has a lower rigidity than other regions of the main body frame 4. Thus, a compression region 13 is formed.

  Reinforcing members 16, that is, additional vertical members 16 a and 16 b provided between the upper chord material 5 and the lower chord material 6 are provided at positions adjacent to the compression region 13. A notch 15 of the upper chord material 5 is disposed between the additional vertical members 16a and 16b. Further, the additional vertical members 16 a and 16 b are provided with a receiving member 17 that extends along the compression region 13 and can support the compressed compression region 13. As shown in FIGS. 3 and 4, the receiving member 17 is supported by the additional vertical member 16a and is supported by the flat steel 17a extending toward the additional vertical member 16b and the additional vertical member 16b. It extends toward the additional vertical member 16a, and has an L-shaped cross section, and is composed of an L steel 17b arranged so that its horizontal side is located at the upper end of the flat steel 17a.

  A bending point reinforcing member 18 is provided between the bent portion of the main body frame 4, that is, between the upper horizontal portion 4a and the inclined portion 4c. In addition, you may make it provide the break point reinforcement member 18 similarly between the lower horizontal part 4b and the inclination part 4c.

  In this embodiment, for example, when an interlayer deformation occurs in the longitudinal direction of the main body frame 4 between the upper floor 2 and the lower floor 3 due to an earthquake motion, the main body frame is interposed via the sliding structure of the non-fixed portion B. 4 moves in the longitudinal direction, and a large compressive force is prevented from acting in the longitudinal direction of the main body frame 4. However, the amount of inter-layer deformation in the longitudinal direction is not so large in small-scale to medium-scale earthquakes and can be accommodated by the displacement of the non-fixed portion B, but the amount of inter-layer deformation is large in large-scale earthquakes. A force acts in the longitudinal direction of the main body frame 4. When a load of a predetermined value or more is applied to the main body frame 4 by this compression force, as shown in FIG. 5, the compression is made to have a lower rigidity than other regions of the main body frame 4 by the notches 15 formed in the upper chord material The region 13 is preferentially deformed and compressed over the other regions of the main body frame 4. At this time, due to the presence of the reinforcing member 16 (additional vertical members 16 a and 16 b) provided between the upper chord member 5 and the lower chord member 6 and the break point reinforcing member 18 provided at the bent portion of the main body frame 4, Is strongly rigid, the compression region 13 is reliably deformed.

  With this compression, the overall length of the main body frame 4, particularly the length of the upper chord material 5 of the upper horizontal portion 4 a is shortened, but the building side receiving beam 10 is provided by the extension member 14 provided on the main body frame side receiving beam 9. Is secured to prevent the body frame 4 from falling.

  In addition, the rigidity of the upper chord member 5 decreases with the deformation of the compression region 13, but the strength necessary for supporting the load of the main body frame 4 by the receiving member 17 is ensured. That is, the compression of the compression region 13 causes the flat steel 17a supported by the additional vertical member 16a to be displaced in the direction of the L steel 17b supported by the additional vertical member 16b, and the upper end of the flat steel 17a is the lower side of the horizontal side of the L steel 17b. And the load of the main body frame 4 is supported by the flat steel 17a via the L steel 17b, and the necessary strength is ensured.

  According to the present embodiment, when an excessive compressive force is applied to the main body frame 4 due to interlayer deformation, the compressive region 13 provided in the upper horizontal portion is positively compressed to absorb the compressive force, and the main body frame 4 This prevents the other area from being deformed, thereby preventing the main body frame from being deformed at an unexpected location other than the horizontal part where the influence of the deformation is small, and preventing the breakdown of the device or the main body frame 4 from falling. it can. Even if the overall length of the main body frame 4 is shortened due to compression, the extension member 14 provided on the main body frame side receiving beam 9 secures the allowance for the building side receiving beam 10. 4 can be prevented from falling. Accordingly, when the passenger conveyor device of an existing building structure is renewed, the dimension between the beams of the building structure cannot be changed, so that the gap between the main body frame 4 and the building-side receiving beams 10 and 12 is provided. Even if the compression risk of the main body frame 4 increases, it is possible to prevent the main body frame 4 from falling due to compression.

  Moreover, by providing the notch 15 in the compression area | region 13, the compression area | region 13 can be made into desired rigidity by a simple method.

  Further, the reinforcing member 16 is provided at a position adjacent to the compression region 13 of the main body frame 4 and the bending point reinforcing member 18 is provided at the bent portion of the main body frame 4, so that the compression region 13 and its surrounding rigidity can be reduced. The difference can be increased, and the compression region 13 can be surely deformed.

  In addition, since the receiving member 17 that is supported by the reinforcing member 16 and extends along the compression region 13 and can support the compressed compression region 13 is provided, the deformation and breakage of the compression region 13 can be achieved. Even if the rigidity of the upper chord member 5 is lowered, the strength necessary for supporting the load of the main body frame 4 can be ensured.

  In the above description, the example in which the compression region 13 is provided in the upper horizontal portion 4a has been described. However, the present invention is not limited thereto, and the compression region 13 may be provided in the lower horizontal portion 4b. Or you may make it provide the compression area | region 13 in both the upper horizontal part 4a and the lower horizontal part 4b.

  Here, the compression area | region 13 can implement | achieve the compression of the stable compression area | region 13 the one provided in the upper horizontal part 4a. That is, when a compressive force is applied to the main body frame 4 of the passenger conveyor device 1 installed between the upper floor 2 and the lower floor 3, an eccentric state occurs in which the force is applied to a position separated by the floor height dimension. The upper horizontal portion 4a generates a moment in the floating direction, and the lower horizontal portion 4b generates a moment in the sinking direction. The compression can be realized more stably by providing the compression region 13 in the upper horizontal portion 4a in which the moment and the compression direction coincide. Although it is possible to provide a compression region in the lower horizontal portion 4b, in this case, the moment and the compression direction described above have a drag relationship, and a large rigidity unintended in design occurs in the compression region, so that stable compression cannot be realized. There is a fear.

  The embodiments of the present invention have been described above. However, the configurations described in the embodiments so far are only examples, and the present invention can be appropriately changed without departing from the technical idea.
