Detailed Description
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
Embodiment mode 1
Fig. 1 is a side view showing an escalator according to embodiment 1 of the present invention. In the figure, an escalator is a passenger conveyor that transports passengers between an upper floor and a lower floor of a building. The upper building portion 10 is disposed on the upper floor. The upper building portion 10 is formed with an upper floor 11. The lower building unit 20 is disposed on a lower floor lower than the upper floor. The lower building portion 20 is formed with a lower floor 21.
A truss 30 of the escalator is provided between the upper building portion 10 and the lower building portion 20. The truss 30 includes a truss main body 3, and an upper supporting structure 4 and a lower supporting structure 5 provided to the truss main body 3, respectively.
The truss main body 3 is arranged along a reference line from the upper building portion 10 to the lower building portion 20. The lengthwise direction of the truss body 3 coincides with the direction along the reference line. The width direction of the truss body 3 coincides with a direction perpendicular to both the length direction and the vertical direction of the truss body 3.
One of the 2 longitudinal ends of the truss body 3 is a longitudinal end 3a facing the upper building portion 10. The upper support structure 4 is provided at the longitudinal upper end 3a of the truss body 3. The longitudinal upper end 3a of the truss body 3 is supported by the upper building unit 10 via the upper support structure 4.
The other of the 2 longitudinal ends of the truss body 3 is a longitudinal lower end 3b facing the lower building unit 20. The lower support structure 5 is provided at the lower end 3b in the longitudinal direction of the truss body 3. The longitudinal lower end 3b of the truss body 3 is supported by the lower building unit 20 via the lower support structure 5.
A plurality of steps 6 connected in a ring shape are supported by the truss main body 3. Each step 6 is circulated between the upper building portion 10 and the lower building portion 20 by a driving force of a driving machine, not shown, provided inside the truss body 3.
A pair of balustrades 7 disposed at both ends in the width direction of the truss main body 3 are provided at the upper portion of the truss main body 3. A moving handrail 8 that moves in synchronization with the steps 6 is provided on the outer periphery of each balustrade 7.
Fig. 2 is a side view showing the upper support structure 4 of fig. 1. Fig. 3 is a plan view showing the upper support structure 4 of fig. 2. Fig. 4 is a sectional view taken along line IV-IV of fig. 2. The upper building portion 10 is formed with a 1 st support surface 12 located at a height lower than the floor 11 of the upper floor and a pair of 2 nd support surfaces 13 located at a height lower than the 1 st support surface 12. The 1 st support surface 12 and the pair of 2 nd support surfaces 13 are located closer to the truss body 3 than the ground 11 on the upper floor.
The pair of 2 nd bearing surfaces 13 are located at the same height from each other, respectively. As shown in fig. 4, the positions of the pair of 2 nd supporting surfaces 13 are separated from each other in the width direction of the truss 30.
The 1 st bearing surface 12 is located between the pair of 2 nd bearing surfaces 13 when viewed from above. Thus, a step portion 14 is formed between each of the pair of 2 nd supporting surfaces 13 and the 1 st supporting surface 12. The dimension of the 1 st support surface 12 in the width direction of the truss body 3 is equal to or less than the dimension in the width direction of the truss body 3.
The truss body 3 has a pair of side frames 35 that constitute both ends in the width direction of the truss body 3. Each side frame 35 has an upper chord member 31, a lower chord member 32, and a plurality of longitudinal members 33.
The upper chord member 31 is disposed along the longitudinal direction of the truss body 3. The lower chord member 32 is disposed below the upper chord member 31 along the longitudinal direction of the truss body 3. The plurality of vertical members 33 are disposed between the upper chord member 31 and the lower chord member 32 along the vertical direction. One end of the vertical member 33 is fixed to the upper chord member 31. The other end of the vertical member 33 is fixed to the lower chord member 32. Some of the vertical members 33 are disposed at the longitudinal upper end 3a and the longitudinal lower end 3b of the truss body 3.
The upper support structure 4 includes a 1 st bridging member 41 and a pair of 2 nd bridging members 42.
The 1 st bridging member 41 is fixed to the longitudinal end 3a of the truss body 3. The 1 st bridging member 41 is an angle member disposed along the width direction of the truss body 3. The 1 st bridging member 41 is fixed between the pair of side frames 35. As shown in fig. 3, the 1 st bridging member 41 is disposed within the range of the truss body 3 in the width direction.
The 1 st bridging member 41 includes: a plate-shaped 1 st fixing portion 411 fixed to the pair of side frames 35 by welding or the like; and a plate-shaped 1 st placing part 412 protruding outward in the longitudinal direction of the truss body 3 from the 1 st fixing part 411. The cross-sectional shape of the 1 st mounting member 41 when cut along a plane perpendicular to the width direction of the truss body 3 is formed into an L shape by the 1 st fixing portion 411 and the 1 st mounting portion 412. The 1 st bridging member 41 is fixed to the truss body 3 in a state where the 1 st placing portion 412 is horizontal and the 1 st fixing portion 411 faces downward.
The 1 st placing portion 412 protrudes from the 1 st fixing portion 411 toward the upper building portion 10. The 1 st placing portion 412 is placed on the 1 st supporting surface 12 with the plurality of spacers 43 interposed therebetween. Each spacer 43 is formed of a plurality of thin plates that overlap each other. The thickness of each spacer 43 is adjusted by adjusting the number of thin plates.
The pair of 2 nd bridging members 42 are fixed to the longitudinal upper ends 3a of the truss body 3, respectively. Further, the pair of 2 nd lap members 42 are disposed on the outer sides in the width direction of the truss main body 3, respectively. The pair of 2 nd bridging members 42 are disposed at positions sandwiching the truss body 3 in the width direction of the truss body 3. Thus, one 2 nd lap member 42 is fixed to one side frame 35. The other 2 nd lap member 42 is fixed to the other side frame 35.
Each of the 2 nd bridging members 42 has: a 2 nd fixing portion 421 fixed to the vertical member 33 positioned at the longitudinal upper end 3a of the truss body 3; and a 2 nd mounting portion 422 protruding outward in the longitudinal direction of the truss body 3 from the 2 nd fixing portion 421. In this example, each 2 nd mounting member 42 is formed in an L-shape by the 2 nd fixing portion 421 and the 2 nd mounting portion 422. Each 2 nd bridging member 42 is fixed to the truss body 3 in a state where the 2 nd mounting portion 422 is horizontal and the 2 nd fixing portion 421 faces downward.
The 2 nd fixing portion 421 is disposed along the longitudinal direction of the vertical member 33, i.e., the vertical direction. The 2 nd fixing portion 421 overlaps the vertical member 33 on the outer side in the width direction of the truss body 3. In this example, the 2 nd fixing portion 421 is a rod-shaped portion having a rectangular cross section. In this example, the 2 nd fixing portion 421 is fixed to the vertical member 33 by a plurality of bolts 45.
Fig. 5 is a side view showing a state where the 2 nd bridging member 42 of fig. 2 is detached from the truss body 3. A plurality of through holes are provided as bolt through holes 34 in the vertical members 33 located at the longitudinal upper end 3a of the truss body 3. The plurality of bolt passage holes 34 are provided at intervals in the longitudinal direction of the vertical member 33.
The 2 nd fixing portion 421 has a plurality of screw holes spaced from each other so as to match the positions of the bolt passing holes 34. As shown in fig. 2, the 2 nd fixing portion 421 is fixed to the vertical member 33 by fastening the plurality of bolts 45 inserted through the bolt passage holes 34 to the respective screw holes of the 2 nd fixing portion 421.
The 2 nd placing portion 422 protrudes from the 2 nd fixing portion 421 toward the upper building portion 10. Further, the 2 nd placing part 422 is placed on the 2 nd supporting surface 13 via the carrier plate 44. Thus, the 2 nd placing portions 422 are respectively disposed on both sides of the 1 st supporting surface 12 in the width direction. The movement of the truss 30 with respect to the upper building portion 10 is restricted in the width direction of the truss 30 by the second placing portion 422 abutting against the step portion 14.
When the 1 st and 2 nd mounting members 41 and 42 are viewed in the width direction of the truss body 3, the length of the 2 nd mounting portion 422 is longer than the length of the 1 st mounting portion 412. The thickness of the 2 nd mounting portion 422 in the vertical direction is greater than the thickness of the 1 st mounting portion 412 in the vertical direction.
The position of the lower surface of the 2 nd mounting part 422 is lower than the position of the lower surface of the 1 st mounting part 412. The position of the upper surface of the 2 nd mounting part 422 is higher than the position of the upper surface of the 1 st mounting part 412. In a state where the 1 st placing part 412 is placed on the 1 st supporting surface 12, the upper surface of the 1 st placing part 412 is located at a position lower than the upper floor level a, which is the height level of the upper floor 11. In addition, in a state where the 2 nd placing part 422 is placed on the 2 nd supporting surface 13, the upper surface of the 2 nd placing part 422 is located at the same height as the upper floor level a.
When the 1 st and 2 nd mounting members 41 and 42 are viewed in the width direction of the truss body 3, the length of the portion of the 2 nd mounting portion 422 to be mounted on the upper building portion 10, i.e., the overlapping amount L2 of the 2 nd mounting portion 422 with respect to the upper building portion 10, is longer than the length of the portion of the 1 st mounting portion 412 to be mounted on the upper building portion 10, i.e., the overlapping amount L1 of the 1 st mounting portion 412 with respect to the upper building portion 10.
Fig. 6 is a side view showing the lower support structure 5 of fig. 1. The lower building portion 20 is formed with a 1 st support surface 22 positioned at a height lower than the floor 21 of the lower floor and a pair of 2 nd support surfaces 23 positioned at a height lower than the 1 st support surface 22. The 1 st support surface 22 and the pair of 2 nd support surfaces 23 are located closer to the truss body 3 than the lower floor 21.
The positional relationship between the 1 st support surface 22 and the pair of 2 nd support surfaces 23 in the lower building portion 20 is the same as the positional relationship between the 1 st support surface 12 and the pair of 2 nd support surfaces 13 in the upper building portion 10. Therefore, a step portion 24 is formed between each of the pair of 2 nd support surfaces 23 and the 1 st support surface 22, similarly to the upper building portion 10.
The lower support structure portion 5 has a 1 st lap member 51 and a pair of 2 nd lap members 52.
The 1 st bridging member 51 is fixed to the longitudinal lower end 3b of the truss body 3. The 1 st bridging member 51 is an angle member disposed along the width direction of the truss body 3. The 1 st mounting member 51 is fixed between the pair of side frames 35. The 1 st bridging member 51 is disposed within the width direction of the truss body 3.
The 1 st bridging member 51 includes: a plate-shaped first fixing portion 511 fixed to the pair of side frames 35 by welding or the like; and a plate-shaped 1 st placing portion 512 protruding outward in the longitudinal direction of the truss body 3 from the 1 st fixing portion 511. The 1 st fixing portion 511 and the 1 st mounting portion 512 have the same configurations as the 1 st fixing portion 411 and the 1 st mounting portion 412 of the upper support structure portion 4.
The 1 st placing portion 512 protrudes from the 1 st fixing portion 511 toward the lower building portion 20. The 1 st placing portion 512 is placed on the 1 st supporting surface 22 with the plurality of spacers 53 interposed therebetween. Each spacer 53 is formed of a plurality of thin plates that overlap each other. The thickness of each spacer 53 is adjusted by adjusting the number of thin plates.
The pair of 2 nd bridging members 52 are disposed on the outer sides in the width direction of the truss body 3. Further, the pair of 2 nd lap members 52 are disposed at positions sandwiching the truss body 3 in the width direction of the truss body 3, respectively.
The pair of second bridging members 52 are fixed to the longitudinal lower ends 3b of the truss bodies 3, respectively. Further, the pair of 2 nd lap members 52 are disposed on the outer sides in the width direction of the truss main body 3, respectively. The pair of 2 nd bridging members 52 are disposed at positions sandwiching the truss body 3 in the width direction of the truss body 3. Thus, one 2 nd lap member 52 is fixed to one side frame 35. The other 2 nd bridging member 52 is fixed to the other side frame 35.
Each 2 nd bridging member 52 has: a 2 nd fixing part 521 fixed to the vertical member 33 positioned at the lower end 3b in the longitudinal direction of the truss body 3; and a 2 nd mounting portion 522 protruding outward in the longitudinal direction of the truss body 3 from the 2 nd fixing portion 521. In this example, each 2 nd mounting member 52 is formed in an L-shape by the 2 nd fixing portion 521 and the 2 nd mounting portion 522. Each 2 nd bridging member 52 is fixed to the truss body 3 in a state where the 2 nd mounting portion 522 is horizontal and the 2 nd fixing portion 521 faces downward.
The 2 nd fixing portion 521 is disposed along the longitudinal direction of the vertical member 33, i.e., the vertical direction. The 2 nd fixing portion 521 overlaps the vertical member 33 on the outer side in the width direction of the truss body 3. In this example, the 2 nd fixing portion 521 is a rod-shaped portion having a rectangular cross section. In this example, the 2 nd fixing portion 521 is fixed to the vertical member 33 by a plurality of bolts 55, similarly to the 2 nd fixing portion 421 of the upper support structure portion 4.
The 2 nd placing portion 522 protrudes from the 2 nd fixing portion 521 toward the lower building portion 20. The 2 nd mounting portion 522 is mounted on the 2 nd support surface 23 via the carrier plate 54. Thus, the 2 nd placing portions 522 are disposed on both sides of the 1 st supporting surface 22 in the width direction. The movement of the truss 30 relative to the lower building unit 20 is restricted in the width direction of the truss 30 by the second mounting portion 522 abutting against the step portion 24.
When the 1 st and 2 nd mounting members 51 and 52 are viewed in the width direction of the truss body 3, the length of the 2 nd mounting portion 522 is longer than the length of the 1 st mounting portion 512. The thickness of the 2 nd mounting portion 522 in the vertical direction is larger than the thickness of the 1 st mounting portion 512 in the vertical direction.
The position of the lower surface of the 2 nd mounting portion 522 is lower than the position of the lower surface of the 1 st mounting portion 512. The position of the upper surface of the 2 nd mounting portion 522 is higher than the position of the upper surface of the 1 st mounting portion 512. In a state where the 1 st placing portion 512 is placed on the 1 st supporting surface 22, the upper surface of the 1 st placing portion 512 is located at a position lower than the height level of the floor surface 21 of the lower floor, that is, the lower floor level B. In addition, in a state where the 2 nd placing portion 522 is placed on the 2 nd supporting surface 23, the upper surface of the 2 nd placing portion 522 is positioned at the same height as the lower floor level B.
When the 1 st and 2 nd mounting members 51 and 52 are viewed in the width direction of the truss body 3, the length of the portion of the 2 nd mounting portion 522 placed on the lower building portion 20, that is, the overlapping amount L4 of the 2 nd mounting portion 522 with respect to the lower building portion 20 is longer than the length of the portion of the 1 st mounting portion 512 placed on the lower building portion 20, that is, the overlapping amount L3 of the 1 st mounting portion 512 with respect to the lower building portion 20.
When the 2 nd bridging member 42 of the upper supporting structure 4 is attached to the existing truss in which the 1 st bridging member 41 is fixed to the longitudinal upper end 3a of the truss body 3, a plurality of bolt passing holes 34 are formed in the vertical member 33 located at the longitudinal upper end 3a of the truss body 3 by machining such as drilling. Thereafter, a pair of the 2 nd lap members 42 are disposed on the outer sides of the truss body 3 in the width direction, and the 2 nd lap members 42 are fixed to the longitudinal direction upper end portion 3a of the truss body 3 by a plurality of bolts 45 inserted through the bolt passage holes 34.
In the case where the 2 nd bridging member 52 of the lower supporting structure 5 is attached to the existing truss in which the 1 st bridging member 51 is fixed to the longitudinal lower end 3b of the truss body 3, the pair of 2 nd bridging members 52 are fixed to the longitudinal lower end 3b of the truss body 3, similarly to the case of the 2 nd bridging member 42 of the upper supporting structure 4.
In the truss 30 of such an escalator, the 2 nd bridging member 42 of the upper supporting structure 4 is disposed on the outer side in the width direction of the truss main body 3. Therefore, the adjustment range of the vertical position of the 2 nd bridging member 42 with respect to the truss body 3 can be increased. Thus, the position of the lower surface of the 2 nd mounting portion 422 of the 2 nd bridging member 42 can be set to a position lower than the position of the upper surface of the truss body 3. Therefore, the 2 nd mounting member 42 can be supported by the upper building portion 10 without placing the 2 nd mounting member 42 on the upper floor 11. This prevents the 2 nd engaging member 42 from protruding largely from the floor surface 11, and the 2 nd engaging member 42 can be prevented from interfering with the user of the escalator.
In the lower support structure 5, the 2 nd bridge member 52 is also disposed on the outer side in the width direction of the truss main body 3. Therefore, the same effect as that of the upper support structure 4 is obtained also in the lower support structure 5.
When the 1 st and 2 nd landing members 41 and 42 are viewed in the width direction of the truss body 3, the overlapping amount L2 of the 2 nd mounting portion 422 with respect to the upper building portion 10 is longer than the overlapping amount L1 of the 1 st mounting portion 412 with respect to the upper building portion 10. Therefore, even if the 1 st mounting part 412 falls off from the upper building part 10 when the building is shaken by an earthquake, a strong wind, or the like, the state in which the 2 nd mounting part 422 is mounted on the upper building part 10 can be maintained. This can more reliably prevent the truss 30 from falling off from the upper building portion 10.
In the lower support structure 5, the overlapping amount L4 of the 2 nd mounting portion 522 with respect to the lower building portion 20 is also longer than the overlapping amount L3 of the 1 st mounting portion 512 with respect to the lower building portion 20. Therefore, the same effect as that of the upper support structure 4 is obtained also in the lower support structure 5.
The position of the lower surface of the 2 nd mounting portion 422 is lower than the position of the lower surface of the 1 st mounting portion 412. Therefore, the 2 nd overlapping element 42 can be more reliably prevented from largely protruding from the floor surface 11. Further, the thickness of the 2 nd mounting portion 422 in the vertical direction can be made thicker than the thickness of the 1 st mounting portion 412, and the strength of the 2 nd mounting portion 422 can be improved.
In the lower support structure portion 5, the position of the lower surface of the 2 nd mounting portion 522 is also lower than the position of the lower surface of the 1 st mounting portion 512. Therefore, the same effect as that of the upper support structure 4 is obtained also in the lower support structure 5.
The position of the 1 st support surface 12 on which the 1 st placing part 412 is placed is lower than the position of the 2 nd support surface 13 on which the 2 nd placing part 422 is placed. Therefore, the 2 nd overlapping element 42 can be more reliably prevented from largely protruding from the floor surface 11.
In the lower building unit 20, the position of the 1 st support surface 22 is also lower than the position of the 2 nd support surface 23. Therefore, the same effect as that of the upper support structure 4 is obtained also in the lower support structure 5.
The 2 nd fixing portion 421 of the 2 nd bridging member 42 is fixed to the vertical member 33 disposed at the longitudinal end 3a of the truss body 3. Therefore, the vertical member 33 can be reinforced by the 2 nd fixing portion 421, and the length of the 2 nd placing portion 422 protruding from the 2 nd fixing portion 421 can be increased. This can increase the overlapping amount L2 of the 2 nd placement portion 422 with respect to the upper building portion 10.
In the lower support structure 5, the 2 nd fixing portion 521 is also fixed to the vertical member 33 disposed at the lower end 3b in the longitudinal direction of the truss body 3. Therefore, the same effect as that of the upper support structure 4 is obtained also in the lower support structure 5.
The 2 nd fixing portion 421 of the 2 nd bridging member 42 is fixed to the vertical member 33 disposed at the longitudinal end 3a of the truss body 3 by a bolt 45. Therefore, the 2 nd fixing portion 421 can be easily fixed to the vertical member 33, and the mounting period, the rebuilding period, and the like of the escalator can be shortened. This can shorten the period during which the operation of the escalator is suspended due to the construction.
In the lower support structure 5, the 2 nd fixing portion 521 is also fixed to the vertical member 33 disposed at the lower end 3b in the longitudinal direction of the truss body 3. Therefore, the same effect as that of the upper support structure 4 is obtained also in the lower support structure 5.
In the above example, the 2 nd fixing portion 421 of the 2 nd overlapping member 42 is fixed to the vertical member 33 by the plurality of bolts 45. However, the 2 nd fixing portion 421 may be fixed to the vertical member 33 by welding. In this way, the fixing operation of the 2 nd fixing portion 421 to the vertical member 33 can be facilitated.
In the above example, the 2 nd fixing portion 521 of the 2 nd overlapping member 52 is fixed to the vertical member 33 by the plurality of bolts 55. However, the 2 nd fixing portion 521 may be fixed to the vertical member 33 by welding. In this way, the fixing operation of the 2 nd fixing portion 521 to the vertical member 33 can be facilitated.
In the above example, the 2 nd mounting member 42 is fixed only to the vertical member 33. However, the 2 nd fixing portion 421 of the 2 nd mounting member 42 may be fixed to the vertical member 33 and at least one of the upper chord member 31 and the lower chord member 32.
In the above example, the 2 nd lap member 52 is fixed only to the vertical member 33. However, the 2 nd fixing portion 521 of the 2 nd mounting member 52 may be fixed to the vertical member 33 and at least one of the upper chord member 31 and the lower chord member 32.
In the above example, the structure of the truss 30 including the upper support structure 4 and the lower support structure 5 is applied to an escalator.
