Description

  The present invention relates to a passenger conveyor.

  The passenger conveyor may be renewed by removing the old passenger conveyor that has been aged and installing a new passenger conveyor at the same location. As a renewal method, as described in JP 2013-67461 A (Patent Document 1), when the existing passenger conveyor is removed, the truss frame, that is, the existing truss frame is left without being removed. There is a method of installing a new truss frame for a new passenger conveyor in the truss frame.

JP 2013-67461 A

  However, what is described in Patent Document 1 described above is that, in the case of renewal, the truss frame of the new passenger conveyor is installed in the storage space of the existing truss frame of the existing passenger conveyor, and the existing truss frame is placed on the building cradle. The existing support angle is mounted, and the new support angle of the new truss frame is mounted on the existing support angle. Therefore, it basically follows the earthquake resistance standards of existing passenger conveyors even after renewal. However, the earthquake resistance of passenger conveyors was strengthened in the wake of the recent large earthquake, and at the time of renewal of passenger conveyors, at least the support angle and the cradle of the building cradle were made larger than that of existing passenger conveyors, and a large layer was It is desired to provide a passenger conveyor with improved seismic resistance that does not drop the truss frame even when a displacement angle occurs and the inter-building beam dimension is relatively large.

  On the other hand, at the time of renewal, it is conceivable to remove the existing support angle from the end of the existing truss frame and provide a new support angle that has a larger allowance than the existing support angle and the building support. Since special processing is required on the side, it is difficult in terms of workability and cost, and generally, as shown in FIG. 10, the building cradle F1a has a size that matches the hanging amount of the existing support angle 3, In order to install a new support angle having a large allowance, it was necessary to remove a part of the building structure side, which caused a heavy burden on the customer and was difficult to realize.

  The present invention has been made from the above-described actual state of the prior art, and an object thereof is to provide a passenger conveyor that can extend the cost of a truss frame for a building structure with a simple structure.

In order to achieve the above object, the present invention provides a passenger conveyor provided with support angles at both end portions of a truss frame installed in a building structure, and a floor material that constitutes an entrance for a user to get on and off. Add frame but with mounted on the main chords of the truss frame, the other is placed on the finished floor surface of the building structure, to secure a large consuming allowance than consuming allowance between the support angle and the building structure And is characterized by providing.

  According to the present invention, one is attached to the main chord member of the truss frame, and the other is placed on the finished floor surface of the building structure, thereby securing a larger allowance than the allowance between the support angle and the building structure. By providing the additional frame, it is possible to extend the cost for the building structure with a simple structure, thereby improving the earthquake resistance of the passenger conveyor in a short time and at a low cost.

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

  In 1st Embodiment, the new escalator installed using the existing truss frame of an existing escalator is illustrated as a passenger conveyor. As shown in FIG. 2, the existing escalator 1 is constructed between the lower floor F1 and the upper floor F2 of the building structure, and extends to the lower floor F1. An existing truss frame 2 having an upper horizontal portion 2b extending toward F2 and an inclined portion 2c formed between the lower horizontal portion 2a and the upper horizontal portion 2b, and the end of the lower horizontal portion 2a The part is provided with an existing lower support angle 3 placed on the building cradle F1a on the lower floor F1, and placed on the building cradle F2a on the upper floor F2 at the end of the upper horizontal part 2b. An existing upper support angle 4 is provided.

  The existing truss frame 2 includes components, for example, a plurality of steps 5 connected endlessly and circulated between the entrances and exits, a step driver 7 installed in the upper machine room 6, and a step driver 7. The upper sprocket 8 to be driven, the lower sprocket 10 installed in the lower machine room 9, the step chain 11 wound around the upper sprocket 8 and the lower sprocket 10, and the side of the step 5 along the traveling direction of the step 5 A balustrade 12 standing on the side and a moving handrail 13 supported by the balustrade 12 are installed.

  In the first embodiment, at the time of renewal, the above-described components are first removed from the existing truss frame 2 and only the existing truss frame 2 is left. In this state, a truss frame (not shown) of the newly installed escalator is installed. Since this new truss frame is stored in the storage space of the existing truss frame 2, it is smaller than the existing truss frame 2 in the longitudinal direction and the short side direction (the lateral width direction of the storage space). And in this 1st Embodiment, when removing the existing escalator 1 and installing a new escalator, in order to extend the wall allowance with respect to a building structure with a simple structure, a device is given in the truss frame termination | terminus part. Yes.

  Specifically, as shown in FIG. 1, one is attached to the main chord member 2d of the existing truss frame 2, and the other is placed on the finished floor surface F1b of the lower floor F1, and the existing lower support angle 3 and An additional frame 14 is provided to secure a larger allowance W2 than the allowance W1 with the building cradle F1a. One side of the additional frame 14 is bolted to the main chord material 2d of the existing truss frame 2, for example, and the other side of the additional frame 14 is placed on the finished floor surface F1b of the lower floor F1. Therefore, no special processing is performed on each of the existing truss frame 2 and the lower floor F1. With such a configuration, the hanging allowance W1 between the existing lower support angle 3 and the building cradle F1a is, for example, 130 mm, but the building allowance W2 for the building structure of the additional frame 14, that is, the lower floor F1, is For example, 450 mm. In this way, by attaching the additional frame 14 to the existing truss frame 2 and improving the earthquake resistance of the existing truss frame 2, the new truss frame stored in the storage space of the existing truss frame 2 and the earthquake resistance of the new escalator are provided. The desired properties can be obtained. 1 shows the structure on the lower floor F1 side, the upper floor F2 side has the same structure.

  According to the first embodiment, one is attached to the main chord member 2d of the existing truss frame 2, and the other is placed on the finished floor surface F1b of the lower floor F1, and the existing lower support angle 3 and the building cradle. By providing the additional frame 14 that secures the allowance W2 larger than the allowance W1 with the F1a, the allowance for the building structure can be extended with a simple structure, thereby enabling a short time and low cost. The escalator can be improved in earthquake resistance. In particular, even when a large interlayer displacement angle is generated by the earthquake motion and the inter-building beam dimension is relatively large, the truss frame can be prevented from falling.
