Fig. 2 is a front view of an elevator according to embodiment 1.
The separator 10 includes a plurality of sheets 11, a plurality of winding mechanisms 12, and a plurality of fasteners 13.
Each of the plurality of sheets 11 is a flexible planar member. The sheet 11 is, for example, a mesh sheet having holes for passing air in the plane. The sheet 11 may also be flame-proof. The sheet 11 is a sheet obtained by covering high-strength polyester filaments with vinyl chloride resin, for example, in a net shape. The sheet 11 is, for example, rectangular in shape. The plurality of sheets 11 may include sheets having different sizes. The sheet 11 is stretched between the plurality of beams 3 arranged one above another. When focusing on the sheet 11b, the upper beam 3b is an example of the first beam. The lower beam 3c is an example of a second beam.

For example, in the case where a plurality of rope passage holes are provided in the sheet 11 so as to be aligned in the vertical direction, the tension rope 14 is passed through the rope passage holes and is included in the surface of the sheet 11. Alternatively, for example, in the case where a rope tube extending in the vertical direction is provided on the sheet 11, the tension rope 14 is contained in the surface of the sheet 11 by passing through the rope tube. The tension cord 14 is wound together with the sheet 11 and stored in the winding mechanism 12.
The plurality of sheets 11 each have a joint 15. The coupling portions 15 are disposed on the left and right sides when the sheet 11 is stretched between the beams 3. The joint 15 is a portion that joins 1 group of sheets 11 adjacently arranged in the front-rear direction. The joint 15 is, for example, a thread fastener, a surface fastener, a button, or the like.
Fig. 4 to 7 are perspective views of the fastener according to embodiment 1.
As shown in fig. 4, the shape of the fastener 13 is コ -shaped. The fastener 13 is formed of, for example, metal. The fastener 13 is provided with a fixing bolt 16. The fixing bolt 16 is provided, for example, in one of 1 set of portions facing each other in the コ -shaped portion of the fastener 13.
As shown in fig. 5, the fastener 13 has teeth 17. The tooth 17 is provided at a portion facing a portion where the fixing bolt 16 is provided. The teeth 17 are wave-shaped portions.
As shown in fig. 6, the fastener 13 has a hole portion 18. The shape of the hole 18 is, for example, circular. The hole 18 is provided in a portion facing a portion where the fixing bolt 16 is provided, for example. The fastener 13 may also have a plurality of hole portions 18. The shape of the hole 18 may be, for example, an oval, an ellipse, a polygon, or the like, and may be provided in any shape, number, and arrangement within a range in which the strength of the fastener 13 is ensured.
As shown in fig. 7, the fastener 13 includes a pressing plate 19. The pressing plate 19 is provided at the front end of the fixing bolt 16. The platen 19 is, for example, a rectangular plate-like member. The pressure plate 19 has a slip-preventing surface 20 on the opposite side of the surface to which the fixing bolt 16 is attached. The non-slip surface 20 is formed of, for example, a rubber material or the like. The anti-slip surface 20 may have irregularities on the surface thereof to engage with the meshes of the sheet 11.
Next, a partitioning method according to embodiment 1 will be described with reference to fig. 8.
Fig. 8 is a vertical cross-sectional view of a beam provided with the partitioning device according to embodiment 1.
In this example, maintenance work is performed in the right path 2 a. The right-hand passage 2a is an example of a first passage. The left side passage 2b is an example of the second passage. The first path is a path 2 for performing maintenance work. The partitioning method in this example includes an expanding process and a fixing process.
The operator rides on the upper part of the car 8 at the uppermost part of the passage 2 a. The operator feeds out the end of the sheet 11a of the separator 10 from the corresponding winding mechanism 12. The worker fixes the end of the fed sheet 11a to the passage 2a side of the highest beam 3a not shown. At this time, the worker clamps the end of the fed sheet 11a with the fastener 13 and fixes it to the flange 5 on the passage 2a side of the beam 3 a. Next, the operator screws in the fixing bolt 16 of the fastener 13. Thereby, the nonslip surface 20 of the presser plate 19 presses the sheet 11a against the flange 5. At this time, the worker may also clamp and fix the portion of the sheet 11a between the tension ropes 14 with the fastener 13. Alternatively, the worker may clamp and fix the portion of the sheet 11 including the tension rope 14 with the fastener 13.
The worker fixes the plurality of sheets 11a to the beam 3a so as to be adjacent in the front-rear direction. When the bracket 6 is attached to the beam 3a, the worker may hold the bracket 6 in the front and rear directions to fix the sheet 11 a.
Next, the worker performs the job of the sheet material 11a setting step as follows, for example. The operator moves the car 8 to the position of the 1 st beam 3b below the beam 3a while feeding out the sheet 11a from the winding mechanism 12. At this time, the worker joins 1 group of sheets 11a arranged adjacent to each other in the front-rear direction to each other by the joining portion 15. The worker places the winding mechanism 12 that has fed out the sheet 11a on the web 4 of the beam 3 b. At this time, the sheet 11a is stretched between the beams 3a and 3 b.
Next, the worker performs the fixing process of the sheet 11a as follows, for example. The worker grips a portion of the sheet 11a stretched between the beams 3a and 3b on the beam 3b side, and forms the fold 21 so that the fold line extends in the front-rear direction. The operator feeds out the end of the other sheet 11b from the corresponding winding mechanism 12. The worker overlaps the fold 21 of the sheet 11a and the end of the sheet 11b with the flange 5 on the passage 2a side. The worker lowers the winding mechanism 12 that has fed out the sheet 11b from the beam 3b toward the path 2 a. The worker clamps the fold 21 of the overlapped sheet 11a and the end of the sheet 11b together with the flange 5 on the passage 2a side with the fastener 13. Next, the worker fastens the sheets 11a and 11b to the beam 3b by screwing the fixing bolts 16 of the fasteners 13. At this time, the worker may pull the tension rope 14 and screw the fixing bolt 16 of the fastener 13 to apply tension to the tension rope 14 of the sheet 11 a.
Next, the worker performs the job of the sheet material setting step 11b as follows, for example. The operator moves the car 8 to the position of the 1 st beam 3c (not shown in fig. 8) below the beam 3b while feeding the sheet 11b fixed to the beam 3b in the fixing step out of the winding mechanism 12. At this time, the worker joins 1 group of sheets 11b adjacently arranged in the front-rear direction to each other by the joining portion 15. The worker places the winding mechanism 12 that has sent out the sheet 11b on the web 4 of the beam 3 c. At this time, the sheet 11b is stretched between the beam 3b and the beam 3 c.
In this way, the worker alternately repeats the stretching step and the fixing step to perform the partition work from the upper portion to the lower portion of the hoistway 1.
As described above, the partitioning device 10 according to embodiment 1 includes the first sheet and the fastening tool 13. The first sheet is stretched from the first passage side of the first beam to the first passage side of the second beam. The fastener 13 clamps and fixes the fold 21 of the first sheet extending forward and backward of the fold line together with the second sheet on the first path side of the second beam. Here, the first beam extends back and forth between the first passage and the second passage. The second beam extends fore-aft below the first beam between the first and second passages. The first passage and the second passage are passages 2 adjacent to each other on the left and right in a hoistway 1 of an elevator. The second sheet is stretched downward on the first path side of the second beam.
The method for partitioning the hoistway 1 according to embodiment 1 includes an expanding step and a fixing step. The stretching step is a step of stretching the first sheet fixed to the first path side of the first beam between the first beam and the second beam on the first path side of the first beam. The fixing step is a step of folding the first sheet with a fold line 21 so that the fold line extends in the front-rear direction after the stretching step, and fixing the first sheet and the second sheet to the first path side of the second beam by sandwiching them with a fastener.
Thereby, the sheet 11 that defines the work area in the hoistway 1 is always stretched on the first path side of the beam 3. The worker or the device under work does not protrude to the adjacent second path in the attachment and detachment of the partition device 10. This can suppress interference with the adjacent second passages even when the partition device 10 is attached and detached. In addition, the sheet 11 is individually stretched between the beams 3 arranged up and down. In general, the difference in the interval between the beams 3 due to the length of the hoistway 1 is small. Therefore, the same partition device 10 can be used for the hoistways 1 having different lengths. This facilitates management of the apparatus for maintenance work. Further, a sheet 11 is set on each of the beams 3 arranged up and down. Therefore, tension is easily applied to the sheet 11. Therefore, the partition work is easily performed.
The first sheet has a joint 15 at the left and right ends. The joint 15 is a portion that is joined to another first sheet stretched between the first beam and the second beam adjacent to each other in the front-rear direction.
The stretching step includes a step of joining the first sheet to another first sheet stretched between the first beam and the second beam adjacent to each other in the front-rear direction.
Thus, the worker can use a plurality of first sheets having different widths in combination. Therefore, the same partition device 10 can be used even in the hoistway 1 having different depths. This facilitates management of the apparatus for maintenance work.
The first sheet includes tension cords 14 in a plane, and the tension cords 14 are stretched in the vertical direction between the first beam and the second beam.
The tension cords 14 contained in the plane are stretched between the first beam and the second beam, thereby suppressing the vibration of the sheet 11 in the out-of-plane direction. Thereby, even when the car 8 travels on the second path, vibration of the sheet 11 of the partitioning device 10 due to wind pressure or the like can be suppressed.
The partition device 10 further includes a winding mechanism 12. The winding mechanism 12 winds and stores the first sheet together with the tension cord 14 with the front-rear direction of the first sheet when the first sheet is stretched between the first beam and the second beam as a winding axis.
The operator can use the first sheet by feeding it to a desired length by the winding mechanism 12. This enables the same partition device 10 to be used even in the hoistway 1 in which the intervals between the beams 3 are different. This facilitates management of the apparatus for maintenance work.
In addition, the fastener 13 presses and fixes the sheet 11 by the slip-resistant surface 20 of the pressing plate 19. Therefore, even if the sheet 11 is a mesh sheet, the sheet 11 is less likely to be entangled by fastening of the fixing bolt 16. In addition, since the sheet 11 is not wound by the fixing bolt 16, the fixing bolt 16 is difficult to rewind. Therefore, the sheet 11 is more reliably fixed.
The partition device 10 may not include the winding mechanism 12. At this time, at least one of the upper and lower end portions of the sheet 11 stretched between the beams 3 may be wound and stored only by the sheet 11. At least one of the upper and lower end portions of the sheet 11 may be folded into a corrugated shape, for example, and stored.
The sheet 11 may not include the tension cord 14.
The partitioning method and the partitioning device 10 according to embodiment 1 can also be applied to an elevator having a beam 3 that is not H-shaped steel. The beam 3 may be, for example, a channel steel.
In the above example, the partitioning method and the partitioning device 10 according to embodiment 1 can be similarly applied even when the left and right sides are reversed.
In embodiment 2, points different from the example disclosed in embodiment 1 will be described in detail. As for the features not described in embodiment 2, any of the features in the example disclosed in embodiment 1 can be adopted.
Fig. 9 is a perspective view of a fastener according to embodiment 2.
The fastener has a first fixing portion 22a and a second fixing portion 22 b. The first fixing portion 22a and the second fixing portion 22b are shaped like コ. In this example, the first fixing portion 22a and the second fixing portion 22b are disposed symmetrically to each other. The first and second fixing portions 22a and 22b are mounted back to back with each other.
The first fixing portion 22a includes a fixing bolt 23. The fixing bolt 23 is, for example, a butterfly bolt. The fixing bolt 23 is provided, for example, on one of 1 set of portions facing each other in the コ -shaped portion of the first fixing portion 22 a. The first fixing portion 22a has a tooth portion 17. The tooth 17 is provided at a portion facing a portion where the fixing bolt 23 is provided. The teeth 17 are wave-shaped portions. The first fixing portion 22a includes a holding plate 19. The pressing plate 19 is provided at the front end of the fixing bolt 23. The platen 19 is, for example, a rectangular plate-like member. The pressure plate 19 has a slip-preventing surface 20 on the opposite side of the surface to which the fixing bolt 23 is attached. The non-slip surface 20 is formed of, for example, a rubber material or the like. The anti-slip surface 20 may have irregularities on the surface thereof to engage with the meshes of the sheet 11.
The second fixing portion 22b includes the fixing bolt 23 and the pressure plate 19, similarly to the first fixing portion 22 a. The second fixing portion 22b has the tooth portion 17 similarly to the first fixing portion 22 a. In the first fixing portion 22a and the second fixing portion 22b, the fixing bolts 23 are provided facing the same direction.
Next, a partitioning method according to embodiment 2 will be described with reference to fig. 10.
Fig. 10 is a vertical cross-sectional view of a beam provided with the partitioning device according to embodiment 2.
The worker performs the operation of the sheet 11a stretching step fixed to the highest-position beam 3a, not shown, in the following manner, for example. The operator moves the car 8 to the position of the 1 st beam 3b below the beam 3a while feeding out the sheet 11a from the winding mechanism 12. At this time, the worker joins 1 group of sheets 11a arranged adjacent to each other in the front-rear direction to each other by the joining portion 15. The worker places the winding mechanism 12 that has fed out the sheet 11a on the web 4 of the beam 3 b. At this time, the sheet 11a is stretched between the beams 3a and 3 b.
Next, the worker performs the fixing process of the sheet 11a as follows, for example.
The worker attaches the fastener 13 to the flange 5 of the beam 3b on the passage 2a side by the first fixing portion 22 a. At this time, the worker is disposed so as to hold the upper end of the flange 5 by the pressing plate 19 and the tooth portion 17 of the first fixing portion 22 a. The first fixing portion 22a is disposed so that the fixing bolt 23 is closer to the passage 2a side than the flange 5. The worker screws in the fixing bolt 23 of the first fixing portion 22a, for example, by hand, thereby fixing the fastener 13 to the beam 3 b.
Then, the worker grips the portion of the sheet 11a stretched between the beams 3a and 3b on the beam 3b side, and forms the fold 21 so that the fold line extends in the front-rear direction. The operator feeds out the end of the other sheet 11b from the corresponding winding mechanism 12. The worker overlaps fold 21 of sheet 11a and the end of sheet 11b so that sheet 11b is on the side of passage 2 a. The worker may form the fold 21 by overlapping the sheet 11a and the sheet 11 b. The worker sandwiches the fold 21 of the overlapped sheet 11a and the end of the sheet 11b between the pressing plate 19 of the second fixing portion 22b of the fastener fixed to the beam 3b and the tooth portion 17. The worker screws in the fixing bolt 23 of the second fixing portion 22b, for example, by hand, and thereby clamps and fixes the fold 21 of the sheet 11a to the beam 3b together with the sheet 11 b. At this time, the worker screws in the fixing bolt 23 in a state where the sheet 11b is turned upward from the fastener 13. The worker may pull the tension rope 14 and screw the fixing bolt 23 of the fastener 13 to apply tension to the tension rope 14 of the sheet 11 a. After the sheet 11a and the sheet 11b are fixed to the beam 3b, the worker drops the winding mechanism 12 that has sent out the sheet 11b from the beam 3b toward the passage 2 a.
Next, the operator performs the operation of the sheet material setting step 11 b. After that, the worker performs the fixing process of the sheet 11 b. In this way, the worker alternately repeats the stretching step and the fixing step to perform the partition work from the upper portion to the lower portion of the hoistway 1.
As described above, the fastener 13 of the spacer 10 according to embodiment 2 includes the first fixing portion 22a and the second fixing portion 22 b. The first fixing portion 22a is attached to the second beam. The second fixing portion 22b sandwiches and fixes the fold of the first sheet together with the second sheet.
The fixing step of the method for partitioning a hoistway 1 according to embodiment 2 includes a first step and a second step. The first step is a step of attaching the fastener 13 to the first path side of the second beam. The second step is a step of clamping and fixing the fold 21 of the first sheet together with the second sheet by the fastener 13 attached to the second beam.
The step of fixing the sheet 11 to the beam 3 is separated into a step of fixing the fastener 13 to the beam 3 and a step of fixing the sheet 11 to the fastener 13. Therefore, the operator may not perform the operation of fixing 3 parts at the same time. Therefore, the partitioning work is more easily performed.
Further, since the fixing bolts 23 are provided in the same direction in the first fixing portion 22a and the second fixing portion 22b, the worker can consistently perform work from one side with respect to the beam 3. Therefore, the partitioning work is more easily performed.
