JP-A 61-243792

  However, in the above-mentioned, the L-shaped material whose base is welded to the building structure, that is, the presser fitting has a vertical surface, and this vertical surface abuts on the vertical surface of the support angle and restricts the movement of the support angle. It is supposed to be. By the way, it is stipulated that the presser fitting has a strength capable of withstanding an acceleration of 0.6 G in the horizontal direction. In order to satisfy this standard, the presser fitting must be firmly welded to the building structure. From the viewpoint of earthquake resistance, it is possible to improve the rigidity of presser foot welding and reduce the risk of shearing of the presser foot welding to the building structure when the presser foot is subjected to a heavy load due to earthquake motion or various vibrations. This is desirable.

  The present invention has been made from the above-described prior art, and an object of the present invention is to provide a passenger conveyor device capable of improving the fastness of welding of the presser fitting.

  In order to achieve the above object, the present invention provides a fixed side portion for immovably fixing one end portion of a main body frame to one building structure, and the other end portion of the main body frame for the other building. A mounting side portion mounted on the structure, and an interval that enables movement of the main body frame in the longitudinal direction between the main body frame and the building structure on which the mounting side portion is positioned. A sliding portion that can follow the longitudinal direction of the main body frame with respect to a positional shift between the main body frame and the building structure, and the other building structure. In a passenger conveyor device that is attached to a body and has a presser fitting that is opposed to both side surfaces of the sliding part and suppresses movement of the main body frame in the short direction, the contact surface between the presser fitting and the sliding part An inclined part is provided, and the presser fitting and the sliding part are connected to the sliding part via the inclined part. Is characterized in that the side bottom parts and into contact.

  In the present invention configured as described above, by providing an inclined portion on the contact surface between the presser fitting and the sliding portion, when the main body frame moves due to earthquake motion or various vibrations, the presser fitting and the sliding portion are inclined. It contacts at the lower end of the side surface of the sliding part via the part. Therefore, since the height of contact of the sliding portion with the presser foot is reduced, the bending moment acting on the presser foot is reduced when the slide portion is in contact with the presser foot. The robustness can be relatively improved.

  In addition, the present invention is characterized in that the inclined portion is formed on a side of the presser fitting that is in contact with the sliding portion, and an upper side in the vertical direction has an inclined direction away from the sliding portion.

  In the present invention configured as described above, the inclined portion provided on the contact surface between the presser fitting and the sliding portion is formed on the contact side with the sliding portion of the presser fitting, and the upper side in the vertical direction is inclined away from the sliding portion. By having the direction, the horizontal force of the sliding part caused by the acceleration of the main body frame can be reduced by the frictional force, so the bending moment acting on the presser bracket is further reduced, and the presser bracket welding is robust Can be improved relatively.

  Furthermore, the present invention is characterized in that the inclined portion is formed on the abutting side of the sliding portion with the presser fitting, and the upper side in the vertical direction has an inclined direction away from the presser fitting.

  In the present invention configured as described above, the inclined portion provided on the contact surface between the presser fitting and the sliding portion is formed on the contact side of the slide portion with the presser fitting, and the upper side in the vertical direction is separated from the presser fitting. By having a direction, even when an inclined part is provided on the sliding part side, the contact height of the sliding part to the presser fitting is reduced, so when the sliding part comes into contact with the presser fitting, The bending moment acting on the presser fitting can be reduced, whereby the fastness of welding of the presser fitting can be relatively improved.

  According to the present invention, the contact portion between the presser fitting and the sliding portion is provided with an inclined portion, and the lower end of the side surface of the slide portion can be brought into contact with the presser fitting. Since the dimensions are reduced, the bending moment acting on the presser fitting can be reduced when the sliding portion comes into contact with the presser fitting. Thereby, the robustness of presser fitting welding can be relatively improved, and a passenger conveyor device having high earthquake resistance can be obtained. Moreover, since it is a simple structure which provides an inclined part in the contact surface of a pressing metal fitting and a sliding part, it can apply easily to a passenger conveyor apparatus.

  Embodiments of a passenger conveyor device according to the present invention will be described below with reference to the drawings.

  The passenger conveyor apparatus 1 is, for example, an escalator, and as shown in FIG. 5, the upper boarding gate that is the other boarding gate that is connected to the upper floor F2 from the lower boarding board 2 that is one boarding board using the lower floor F1. 3, a step 4 connected endlessly and moving, a handrail 5 moving in synchronization with the step 4, a balustrade 6 standing on both sides of the step 4 and forming a travel path of the handrail 5, etc. With structural parts.

  Further, the longitudinal direction of the structural part such as the balustrade 6, that is, the main body frame 7 of the total length L from the lower entrance 2 to the upper entrance 3 via the lower curved path 4A, the inclined path 4B, and the upper curved path 4C, The lower horizontal portion 7A, the inclined portion 7B, and the upper horizontal portion 7C are connected to each other and are arranged between the lower floor F1 and the upper floor F2 so as to straddle the seismic isolation floor Y of the building structure. The main body frame 7 is made of, for example, a steel material, and the beam body 7a fixed to the main body frame 7 is firmly integrated with the upper building structure 8 so as not to move and to be detached. Thus, the fixed side portion 1A is formed.

  Further, as shown in FIG. 2, the edge portion 7b of the lower end portion of the main body frame 7 forms a mounting side portion 1B to which seismic measures are applied, and is separated from the lower floor F1 or dropped. It is to be prevented. And if a large interlayer displacement angle occurs due to an earthquake or the like, and the interval between the main body frame 7 and the receiving beam 9 which is the building structure on the lower floor F1 side becomes excessive, or conversely, it becomes too small. It is illustrated. That is, the sliding part 10 is provided between the terminal part 2A of the lower entrance 2 which is the mounting side part 1B of the main body frame 7, and the receiving beam 9 of the lower floor F1. The sliding portion 10 is made of L-shaped steel, and a plurality of vertical sides of the sliding portion 10 are fixed to the lower edge portion 7b of the main body frame 7, and a plurality of the sliding portions 10 are provided on a horizontal side of the beam body 10a via a predetermined gap. And a bolt 10b whose tip is in contact with the smooth plate 9a. In addition, as shown in FIG. 1, both side surfaces of the beam body 10a are vertical surfaces. Moreover, the smooth plate 9a is being fixed to the upper surface of the receiving beam 9 with the welding 9b, as shown in FIG.

  Further, as shown in FIGS. 1 to 3, presser fittings 11 that are opposed to both side surfaces of the beam body 10 a of the sliding portion 10 and suppress the movement of the main body frame 7 in the short direction are attached to the smooth plate 9 a. ing. The presser fitting 11 is fixed to the smooth plate 9a by welding 11a.

  And in the 1st Example, the device is given in order to improve the robustness of presser fitting welding. Specifically, as shown in FIGS. 1 and 4, an inclined portion 12 is provided on the contact surface between the presser fitting 11 and the beam body 10 a of the sliding portion 10, and the lower end of the side surface of the beam body 10 a contacts the presser fitting 11. It is possible to contact. The inclined portion 12 is formed on the contact side of the presser fitting 11 with the beam body 10a, and the upper side in the vertical direction has an inclination direction away from the beam body 10a.

  In the first embodiment, when the main body frame 7 tries to move in one direction in the short direction due to earthquake motion or various vibrations, one side surface of the beam body 10a of the sliding portion 10 presses the presser fitting 11. . At this time, an inclined portion 12 having an inclination direction in which the upper side in the vertical direction is separated from the beam body 10a is provided on the contact side of the presser fitting 11 with the beam body 10a, and the side surface of the beam body 10a is a vertical surface. Therefore, the lower end of the side surface of the beam body 10 a comes into contact with the presser fitting 11.

  Thereby, as shown in FIG. 4, the contact height dimension h of the beam body 10a to the presser fitting 11 can be lowered. Here, the bending moment M acting on the presser fitting 11 is expressed by the equation M = f × h using the horizontal force f acting on the beam body 10a generated by the acceleration of the main body frame 7 and the contact height dimension h. Desired.

  If both the presser fitting 11 and the beam body 10a do not have an inclined portion and contact each other on vertical surfaces as in the conventional case, the size of f does not change, and the contact height dimension for obtaining the bending moment h ′ = h + (thickness of beam body 10a / 2), which is larger than h.

  Therefore, according to the first embodiment, as shown in FIG. 4, since the contact height dimension h of the beam body 10a to the presser fitting 11 can be lowered, the bending acting on the presser fitting 11 can be performed. The moment M can be reduced.

  Further, when the inclined portion 12 is formed on the presser fitting 11 side as in the first embodiment, the horizontal force f acting on the beam body 10a is in the vertical direction of the contact surface perpendicular to the contact surface. The force f1 and the force f2 in the contact surface horizontal direction (inclination direction) parallel to the contact surface are divided into two forces. At this time, a frictional force acts on the contact surface in proportion to the force f1 in the contact surface vertical direction. This frictional force acts as a drag against the force f2 in the contact surface horizontal direction (inclination direction) (works in the opposite direction to the direction of movement), and as a result, in the contact surface horizontal direction (inclination direction). This produces an effect of reducing the force f2. As a result, since the horizontal force f in the mathematical formula for obtaining the bending moment is also reduced, the bending moment is also reduced.

  That is, when the inclined portion 12 is formed on the side of the presser fitting 11 as in the first embodiment, the horizontal force f acting on the beam body 10a due to the frictional force is also reduced, so that it acts on the presser fixture 11. The bending moment M can be further reduced.

  As described above, according to the first embodiment, the inclined portion 12 is provided on the contact surface between the presser fitting 11 and the beam body 10a of the sliding portion 10, and the lower end of the side surface of the beam body 10a is in contact with the presser fitting 11. By making it possible, when the beam body 10a abuts against the presser fitting 11 when the beam body 10a abuts against the presser fitting 11, the bending moment M acting on the presser fitting 11 is reduced. Can be reduced. In particular, the inclined portion 12 is formed on the side of the presser fitting 11 in contact with the beam body 10a, and has an inclined direction in which the upper side in the vertical direction separates from the beam body 10a, thereby acting on the beam body 10a by frictional force. Since the force f is also reduced, the bending moment M acting on the presser fitting 11 can be further reduced. Thereby, the robustness of presser fitting welding can be relatively improved, and a passenger conveyor device having high earthquake resistance can be obtained. Further, the required strength can be ensured while reducing the welding amount of the weld 11a for fixing the presser fitting 11 as compared with the conventional structure. Furthermore, since the inclined portion 12 is provided on the contact surface between the presser fitting 11 and the beam body 10a, it can be easily applied to a passenger conveyor device.

  Here, a second embodiment of the passenger conveyor apparatus according to the present invention will be described with reference to FIGS. In addition, the same code | symbol is attached | subjected to the thing equivalent to what was mentioned above, and repeated description is abbreviate | omitted.

  The difference between the second embodiment and the first embodiment described above is the configuration of the inclined portion 120 provided on the contact surface between the presser fitting 110 and the beam body 100a of the sliding portion 100. Specifically, as shown in FIGS. 6 and 9, an inclined portion 120 having an inclination direction in which the upper side in the vertical direction is away from the presser fitting 110 is formed on the side of the beam body 100 a that contacts the presser fitting 110. Yes. The side surface of the presser fitting 110 shown in the second embodiment is a vertical surface, and the presser fixture 110 is fixed to the smooth plate 9a by welding 110a.

  In the second embodiment, when the main body frame 7 tries to move in one direction in the short direction due to earthquake motion or various vibrations, one side surface of the beam body 100a of the sliding portion 100 presses the presser fitting 110. . At this time, an inclined portion 120 having an inclined direction in which the upper side in the vertical direction is away from the presser fitting 110 is provided on the side of the beam body 100a that contacts the presser fixture 110, and the side surface of the presser fitting 110 is a vertical surface. Therefore, the lower end of the side surface of the beam body 100 a comes into contact with the presser fitting 110. Accordingly, by reducing the contact height dimension h of the beam body 100a to the presser fitting 110, the bending moment M acting on the presser fitting 110 when the beam body 100a contacts the presser fitting 110 is reduced. Can be reduced. This is because the bending moment M is obtained by an equation of M = f × h, and the bending moment M is reduced under the condition that the value of the contact height dimension h is reduced.

  In the case where both the presser fitting 110 and the beam body 100a are in contact with each other on the vertical surfaces as in the prior art, the size of f does not change and the contact height dimension for obtaining the bending moment is not changed. Since h ′ = h + (thickness of the beam body 100a / 2), which is larger than h, the bending moment is larger than that in the second embodiment.

  According to the second embodiment, the inclined portion 120 provided on the contact surface between the presser fitting 110 and the beam body 100a of the sliding portion 100 is formed on the contact side of the beam body 100a with the presser fitting 110, Since the upper side in the vertical direction has an inclination direction away from the presser fitting 110, even when the inclined portion 120 is provided on the beam body 100a side, the contact height dimension of the beam body 100a to the presser fitting 110 is reduced, When 100a abuts against the presser fitting 110, the bending moment acting on the presser fitting 110 is reduced, thereby making it possible to relatively improve the fastness of welding of the presser fitting.

  In addition, this invention is not limited to the Example mentioned above, Various modifications are included. For example, the above-described embodiments have been described in detail for easy understanding of the present invention, and are not necessarily limited to those having all the configurations described. Further, a part of the configuration of one embodiment can be replaced with the configuration of another embodiment, and the configuration of another embodiment can be added to the configuration of one embodiment. Furthermore, it is possible to add, delete, or replace other configurations for a part of the configuration of each embodiment.
