Description

TECHNICAL FIELD

[0001] The present application relates to an installation structure and an installation method of a landing sill device of an elevator. BACKGROUND

[0002] In the conventional landing sill device of an elevator, a plurality of sill mounting members 1 are arranged in the lateral width direction of a landing entrance, in a manner that the support arms 1b are vertical and the mounting portions 1a are anchored to the wall surface of the shaft side of the concrete floor 11. The upper surfaces of the placement portions 2b of the sill receiving members 2, i.e., the sill placement surfaces, are on the same level, and the mounting portions 2a of the sill receiving members 2 are tightly fixed to the support arms 1b of the respective sill mounting members 1 by means of the bolts 12 and the nuts 13. The concrete receiving plates 3 are extended over the entire area in the lateral width direction of the landing entrance, in a manner that the concrete receiving portions 3b are placed on the sill placement surfaces of the respective placement portions 2b and the abutting portions 3a abut against the wall surface of the shaft side of the concrete floor 11. The sill members 5 are tightly fixed to the placement portions 2b of the respective sill receiving members 2 by means of the bolts 14 and the nuts 15, with the concrete receiving portions 3b interposed therebetween, and are extended in the lateral width direction of the landing entrance (see, for example, Patent Document 1).

[0003] According to the above-described landing sill device of an elevator, since the gap between the concrete floor 11 and the sill members 5 is blocked by the concrete receiving plates 3, the steel plate for blocking the gap, which has been conventionally prepared for each landing, is not required, and thus the landing sill device can be easily attached. Further, when the mortar 7, 8 is applied to the concrete floor 11, the mortar can be applied thicker on the side of the sill members 5, and thus sufficient strength can be obtained. Therefore, it is also possible to prevent the occurrence of cracks in the processed surface of the landing floor.

[0007] PROBLEMS TO BE SOLVED BY THE INVENTION

[0008] However, in the conventional landing sill device of an elevator, since the gap between the concrete floor 11 and the sill members 5 is blocked by the abutting portions 3a of the concrete receiving plates 3 abutting against the wall surface of the shaft side of the concrete floor 11, and the concrete receiving portions 3b of the concrete receiving plates 3 are interposed between the sill members 5 and the placement portions 2b of the respective sill receiving members 2 and are tightly fixed by means of the bolts 14 and the nuts 15, when the position of one of the sill members 5 and the concrete receiving plates 3 is adjusted, the position of the other one is sometimes deviated, and the installation time is lengthened.

[0009] The present application has been made to solve the above-described problems.

[0010] Means for solving the problems

[0011] The installation structure of the landing sill device of the elevator of the present application is provided with: a sill disposed at the lower portion of an entrance that connects a shaft and a landing; a sill support member fixed to the inner side wall of the shaft below the entrance and supporting the sill; a first weir plate that is hung downward from the sill; a second weir plate placed on the upper surface of the sill support member, one end of the second weir plate abutting against the wall surface, the other end of the second weir plate facing the side opposite to the wall surface; and a third weir plate, one end of which is placed on the upper surface of the sill support member or the upper surface of the second weir plate and abutting against the side surface of the sill support member facing the side opposite to the wall surface or the side surface of the second weir plate facing the side opposite to the wall surface, the other end of the third weir plate standing up and abutting against the first weir plate, the first weir plate, the second weir plate, and the third weir plate blocking the gap between the sill and the wall surface.

[0012] The installation method of the landing sill device of the elevator of the present application blocks the gap between the sill and the wall surface with a first weir plate, a second weir plate, and a third weir plate, the sill being disposed at the lower portion of an entrance that connects a shaft and a landing and being supported by a sill support member fixed to the inner side wall of the shaft below the entrance, wherein the installation method of the landing sill device of the elevator includes the following steps: a first weir plate installation step of making the first weir plate hang downward from the sill; a second weir plate installation step of placing the second weir plate on the upper surface of the sill support member, abutting one end of the second weir plate against the wall surface, and facing the other end of the second weir plate toward the side opposite to the wall surface; and a third weir plate installation step performed after the first weir plate installation step and the second weir plate installation step of placing one end of the third weir plate on the upper surface of the sill support member or the upper surface of the second weir plate and abutting against the side surface of the sill support member facing the side opposite to the wall surface or the side surface of the second weir plate facing the side opposite to the wall surface, and standing up the other end of the third weir plate to abut against the first weir plate.

[0013] Effects of the invention

[0014] In the installation structure and the installation method of the landing sill device of the elevator of the present application, even if the relative positions of the sill and the wall surface change, the state of the third weir plate leaning against the first weir plate to block the gap between the first weir plate and the second weir plate can be maintained without the need to readjust the positions of the first weir plate, the second weir plate, and the third weir plate, and thus the installation time can be reduced.

[0027] The building structure wall 3 divides the hoistway 1 from the hall 2. The building structure wall 3 is formed with a wall hole portion 3a. The building structure wall 3 is made of, for example, concrete.

[0028] The finishing wall 4 is provided on a side opposite the hoistway 1 from the building structure wall 3. The finishing wall 4 is provided around the door frame 8.

[0029] The building structure floor 5 divides a floor of the hall 2 from a floor below the hall 2. The building structure floor 5 extends from the building structure wall 3 of the hoistway 1 to a side opposite the hoistway 1.

[0030] The finishing floor 6 is provided above the building structure floor 5. The finishing floor 6 extends from a side 9a of the sill 9 facing the hall 2 to a side opposite the hoistway 1.

[0031] The entrance 7 is provided at the wall hole portion 3a of the building structure wall 3. The entrance 7 communicates the hoistway 1 and the hall 2.

[0032] The door frame 8 is disposed at the wall hole portion 3a of the building structure wall 3 of the hall 2. The door frame 8 forms the entrance 7.

[0033] The sill 9 is disposed at a lower portion of the entrance 7. The sill 9 is located inside the hoistway 1. The sill 9 is formed with a groove portion 9c at a lower surface 9b thereof, the groove portion 9c extending in a width direction of the entrance 7. The sill 9 is formed with a groove portion 9d at the side 9a thereof, the groove portion 9d extending in the width direction of the entrance 7.

[0034] The sill support member 10 is fixed to a wall surface la of the hoistway 1 inside a side opposite the hoistway 1 below the entrance 7. The sill support member 10 supports the sill 9. The sill support member 10 has a wall side support member 13 and a sill side support member 14.

[0035] The wall side support member 13 has a wall side fixing piece 13a and a wall side connecting piece 13b.

[0036] The wall side fixing piece 13a extends along the wall surface 1a. The wall side fixing piece 13a abuts against the wall surface 1a. The wall side fixing piece 13a extends in the width direction of the entrance 7. The wall side fixing piece 13a extends in the up-down direction. The wall side fixing piece 13a is formed with an elongated hole 13c that is longer in the width direction of the entrance 7. The wall side fixing piece 13a is fixed to the wall surface 1a by a first joining member 15. The first joining member 15 has an anchor bolt 15a, a nut 15b, and a washer 15c. The anchor bolt 15a is driven into the wall surface 1a. The threaded portion of the anchor bolt 15a passes through the elongated hole 13c of the wall side fixing piece 13a and the washer 15c in that order. The nut 15b is screwed into the threaded portion of the anchor bolt 15a to fasten the wall side fixing piece 13a to the wall surface 1a with the washer 15c.

[0037] The wall side connecting piece 13b extends from the wall side fixing piece 13a toward the side opposite the wall surface 1a. The wall side connecting piece 13b extends in the depth direction of the entrance 7. The wall side connecting piece 13b extends in the up-down direction. The wall side connecting piece 13b is formed with an elongated hole 13d that is longer in the depth direction of the entrance 7. The wall side connecting piece 13b has an upper surface 13e at the end portion thereof on the upper side. The upper surface 13e extends in the depth direction of the entrance 7. The upper surface 13e extends in the width direction of the entrance 7.

[0038] The threshold side supporting member 14 has a threshold side fixing piece 14a and a threshold side connecting piece 14b.

[0039] The threshold side fixing piece 14a extends along the lower surface 9b of the threshold 9. The threshold side fixing piece 14a extends in the width direction of the entrance 7. The threshold side fixing piece 14a extends in the depth direction of the entrance 7. The threshold side fixing piece 14a is formed with a round hole 14c. The threshold side fixing piece 14a is fixed to the lower surface 9b of the threshold 9 by a second joining member 16. The second joining member 16 has a bolt 16a and a nut 16b. The head portion of the bolt 16a is fitted into a groove portion 9c formed in the lower surface 9b of the threshold 9. The threaded portion of the bolt 16a passes through the round hole 14c of the threshold side fixing piece 14a. The nut 16b is screwed into the threaded portion of the bolt 16a to fasten the threshold side fixing piece 14a to the lower surface 9b of the threshold 9.

[0040] The threshold side connecting piece 14b extends from the threshold side fixing piece 14a toward the lower side. The threshold side connecting piece 14b extends in the up-down direction. The threshold side connecting piece 14b extends in the depth direction of the entrance 7. The threshold side connecting piece 14b is formed with an elongated hole 14d that is longer in the up-down direction. The threshold side connecting piece 14b has a side surface 14e at the end portion thereof on the side closer to the wall surface 1a. The side surface 14e faces toward the wall surface 1a side. The side surface 14e extends in the up-down direction. The side surface 14e extends in the width direction of the entrance 7. The side surface 14e is located at a position higher than the upper surface 13e. The upper surface 13e is located between the side surface 14e and the wall surface 1a.

[0041] The wall side connecting piece 13b of the wall side supporting member 13 and the sill side connecting piece 14b of the sill side supporting member 14 are fixed by a third joining member 17. The third joining member 17 has a bolt 17a, a nut 17b, a washer 17c, and a washer 17d. The threaded portion of the bolt 17a passes through the washers 17c, 17d, the long hole 14d of the sill side connecting piece 14b, the long hole 13d of the wall side connecting piece 13b in this order. The nut 17b is screwed into the threaded portion of the bolt 17a to fasten the wall side connecting piece 13b and the sill side connecting piece 14b with the washers 17c, 17d.

[0042] Thus, the sill 9 is fixed to the wall surface la by the sill supporting member 10, so that the position of the sill 9 can be adjusted in the width direction, the height direction, and the depth direction of the doorway 7.

[0043] Further, the long hole 13c, the long hole 13d, the round hole 14c, and the long hole 14d of the sill supporting member 10 can be, for example, long holes, round holes, or notches, and the orientation of the long holes and the notches can be appropriately determined.

[0044] Further, the sill supporting member 10 can have, for example, one wall side supporting member 13 and two sill side supporting members 14. In this case, the wall side supporting member 13 can have one wall side fixing piece 13a and two wall side connecting pieces 13b.

[0045] Further, the wall side supporting member 13 and the sill side supporting member 14 can be integrally formed by bending one member in a plate shape, for example.

[0046] Further, in the case where the wall surface la of the shaft 1 is made of iron, the sill supporting member 10 can be attached to the wall surface la of the shaft 1 by welding, for example.

[0047] Further, the sill 9 is supported by three sill supporting members 10, but can be supported by two or more sill supporting members 10.

[0048] The dam plate 11 closes the gap 18 between the sill 9 and the wall surface la. The dam plate 11 has a first dam plate 19, a second dam plate 20, and a third dam plate 21.

[0049] The first dam plate 19 is suspended downward from the sill 9. The first dam plate 19 is sandwiched between the sill 9 and the sill supporting member 10. The first dam plate 19 has a fixing portion 19a and a blocking portion 19b.

[0050] The fixing portion 19a is sandwiched between the sill 9 and the sill side supporting member 14. The fixing portion 19a extends along the lower surface 9b of the sill 9. The fixing portion 19a extends in the width direction of the doorway 7. The fixing portion 19a extends in the depth direction of the doorway 7. The fixing portion 19a extends toward the wall surface la side. The fixing portion 19a does not protrude more than the end portion of the sill 9 on the side opposite to the landing 2. The fixing portion 19a is formed with an elongated hole 19c that is longer in the width direction of the doorway 7. In addition, the fixing portion 19a extends to the same length as the blocking portion 19b in the width direction of the doorway 7, but can extend shorter than the blocking portion 19b or longer than the blocking portion 19b.

[0051] The threaded portion of the bolt 16a passes through the elongated hole 19c of the fixing portion 19a and the circular hole 14c of the sill side fixing piece 14a in that order. The nut 16b is screwed into the threaded portion of the bolt 16a to fasten the fixing portion 19a and the sill side fixing piece 14a to the lower surface 9b of the sill 9.

[0052] The blocking portion 19b extends downward from the end portion of the fixing portion 19a on the side of the wall surface la. The blocking portion 19b extends in the vertical direction. The blocking portion 19b extends longer than the wall hole portion 3a of the building structure wall 3 in the width direction of the doorway 7. The blocking portion 19b is disposed between the wall surface la and the side surface 14e of the sill supporting member 10. A gap is left between the blocking portion 19b and the wall surface la. A gap is left between the blocking portion 19b and the side surface 14e of the sill supporting member 10. The blocking portion 19b can follow along the side surface 14e of the sill supporting member 10. The blocking portion 19b can abut against the side surface 14e of the sill supporting member 10.

[0053] The 2nd weir plate 20 is placed on the upper surface 13e of the sill supporting member 10. The 2nd weir plate 20 abuts against the upper surface 13e of the sill supporting member 10. One end 20a of the 2nd weir plate 20 abuts against the wall surface la. The other end 20b of the 2nd weir plate 20 faces the side opposite to the wall surface la. The 2nd weir plate 20 has a 1st piece 20c and a 2nd piece 20d.

[0054] The 1st piece 20c is placed on the upper surface 13e of the sill supporting member 10. The 1st piece 20c abuts against the upper surface 13e of the sill supporting member 10. The 1st piece 20c extends longer than the wall hole portion 3a of the building structure wall 3 in the width direction of the doorway 7. The 1st piece 20c extends in the depth direction of the doorway 7. The 1st piece 20c has the one end 20a.

[0055] The second piece 20d extends upward from the end of the first piece 20c on the side opposite the wall surface 1a. The second piece 20d extends in the up-down direction. The second piece 20d extends in the width direction of the entrance 7. The second piece 20d has a side surface 20e toward the side opposite the wall surface 1a. The second piece 20d has the other end 20b. In addition, the second piece 20d can extend to the same length as the first piece 20c in the width direction of the entrance 7, but can also extend shorter than the first piece 20c or longer than the first piece 20c.

[0056] The one end 21a of the third weir plate 21 is placed on the upper surface 13e of the sill support member 10. The one end 21a of the third weir plate 21 abuts against the upper surface 13e of the sill support member 10. The one end 21a of the third weir plate 21 abuts against the side surface 20e of the second weir plate 20 on the side opposite the wall surface 1a. The other end 21b of the third weir plate 21 stands up against the first weir plate 19. The third weir plate 21 extends longer than the wall hole portion 3a of the building structure wall 3 in the width direction of the entrance 7. The third weir plate extends in the depth direction of the entrance 7. The third weir plate extends in the up-down direction.

[0057] As described above, the first weir plate 19, the second weir plate 20, and the third weir plate 21 block the gap 18 between the sill 9 and the wall surface 1a.

[0058] The filling material 12 is filled between the sill 9 and the wall surface 1a. The filling material 12 is filled in a liquid state and solidifies after being filled. The filling material 12 is, for example, mortar.

[0059] In the installation structure of the landing sill device of the elevator in Embodiment 1, there are provided: a sill 9 disposed at the lower portion of an entrance 7 that communicates between a hoistway 1 and a landing 2; a sill support member 10 fixed to the wall surface 1a on the inner side of the hoistway 1 below the entrance 7 and supporting the sill 9; a first weir plate 19 that hangs downward from the sill 9; a second weir plate 20 placed on the upper surface 13e of the sill support member 10, one end 20a of the second weir plate 20 abutting against the wall surface 1a, and the other end 20b of the second weir plate 20 facing the side opposite the wall surface 1a; and a third weir plate 21 having one end 21a placed on the upper surface 13e of the sill support member 10 and abutting against the side surface 20e of the second weir plate 20 on the side opposite the wall surface 1a, and the other end 21b of the third weir plate 21 standing up against the first weir plate 19, the first weir plate 19, the second weir plate 20, and the third weir plate 21 blocking the gap 18 between the sill 9 and the wall surface 1a.

[0060] Thus, even if the relative positions of the sill 9 and the wall surface la are changed, the state in which the third weir plate 21 leans against the first weir plate 19 to block the gap between the first weir plate 19 and the second weir plate 20 is maintained, and therefore it is not necessary to readjust the positions of the first weir plate 19, the second weir plate 20, and the third weir plate 21, and the installation time can be reduced.

[0061] Further, when the filler material 12 is filled between the sill 9 and the wall surface la, even if the third weir plate 21 is pressed by the filler material 12, since one end 21a of the third weir plate 21 is pressed against the second weir plate 20 and the other end 21b of the third weir plate 21 is pressed against the first weir plate 19, it is not necessary to provide a member for fixing the third weir plate 21 to the first weir plate 19 and the second weir plate 20, the manufacturing cost can be reduced, and the installation time can be reduced.

[0062] Further, since the second weir plate 20 is placed and supported on the upper surface 13e of the sill support member 10, the deflection of the second weir plate 20 that occurs when a vertical load acts on the second weir plate 20 can be suppressed.

[0063] Further, even if the gap 18 between the sill 9 and the wall surface la becomes large, since the second weir plate 20 is installed between the wall surface la and the third weir plate 21, the inclination of the third weir plate 21 can be maintained within a desired range, and the deflection of the third weir plate 21 that occurs when a vertical load acts on the third weir plate 21 can be suppressed.

[0064] In the installation structure of the landing sill device of the elevator in Embodiment 1, the first weir plate 19 is sandwiched between the sill 9 and the sill support member 10.

[0065] Thus, the member for making the first weir plate 19 hang down with respect to the sill 9 can be reduced, the manufacturing cost can be reduced, and the installation time can be reduced.

[0066] In the installation structure of the landing sill device of the elevator in Embodiment 1, the second weir plate 20 has a first piece 20c that has one end 20a of the second weir plate 20, and a second piece 20d that extends upward from the side of the first piece 20c opposite the wall surface la and has the other end 20b and the side surface 20e of the second weir plate 20, and one end 21a of the third weir plate 21 is placed on the upper surface 13e of the sill support member 10 and abuts against the side surface 20e of the second weir plate 20.

[0067] Thus, even if the installation intervals of the plurality of sill support members 10 in the width direction of the doorway 7 become large, the deflection of the second weir plate 20 that occurs when a vertical load acts on the second weir plate 20 can be suppressed.

[0068] Further, the end 21a of the third weir plate 21 can be prevented from being detached from the other end 20b of the second weir plate 20, and a member for fixing the end 21a of the third weir plate 21 is not required, so that the manufacturing cost can be reduced, and the installation time can be reduced.

[0069] Next, the installation method of the landing sill device of the elevator in Embodiment 1 will be described with reference to the drawings.

[0070] Figure 4 is a flowchart of the installation method of the landing sill device of the elevator in Embodiment 1. The installation method of the landing sill device of the elevator in Embodiment 1 is constituted of the first to eighth processes shown in S1 to S8 in Figure 4

[0071] In the first process, a position serving as a reference for installing the sill 9 is determined. The first process is performed as follows.

[0072] For example, a position vertically disposed between the top and the bottom of the hoistway 1 is set as the reference of the position in the width direction and the depth direction of the doorway 7. For example, the height of the floor finish surface is set as the reference of the position in the vertical direction.

[0073] In the second process, the sill support member 10 is installed to the wall surface la of the hoistway 1. The second process is performed as follows.

[0074] The wall side support member 13 of the sill support member 10 is installed to the wall surface la. The anchor bolt 15a is driven into a prescribed position of the wall surface la. The threaded portion of the anchor bolt 15a is sequentially passed through the long hole 13c of the wall side fixing piece 13a of the wall side support member 13 and the washer 15c. The nut 15b is screwed into the threaded portion of the anchor bolt 15a to temporarily fasten, so that the wall side fixing piece 13a is fastened to the wall surface la with the washer 15c.

[0075] The sill side support member 14 of the sill support member 10 is installed to the wall side support member 13. The threaded portion of the bolt 17a is sequentially passed through the washer 17c, the long hole 14d of the sill side connecting piece 14b of the sill side support member 14, the long hole 13d of the wall side connecting piece 13b of the wall side support member 13, and the washer 17d. The nut 17b is screwed into the threaded portion of the bolt 17a to temporarily fasten, so that the wall side connecting piece 13b and the sill side connecting piece 14b are fastened with the washer 17c and the washer 17d.

[0076] Alternatively, the sill side support member 14 can be installed to the wall side support member 13 before the second process.

[0077] In the third process, the sill 9 is installed to the sill support member 10. The third process is performed as follows. ​

[0078] The sill 9 is installed to the sill side supporting member 14. The head of the bolt 16a is inserted into the groove portion 9c of the sill 9. The threaded portion of the bolt 16a is passed through the round hole 14c of the sill side fixing piece 14a of the sill side supporting member 14. The nut 16b is screwed into the threaded portion of the bolt 16a to be temporarily fastened, thereby fastening the sill side fixing piece 14a to the lower surface 9b of the sill 9.

[0079] Further, the sill 9 can be installed to the sill supporting member 10 before the third step.

[0080] In the fourth step (first dam plate installation step), the first dam plate 19 is installed. The fourth step is performed simultaneously with the third step. The fourth step is performed as follows.

[0081] The first dam plate 19 is installed when the sill 9 is installed to the sill side supporting member 14. The fixing portion 19a of the first dam plate 19 is sandwiched between the sill 9 and the sill side supporting member 14, so that the blocking portion 19b of the first dam plate 19 extends downward from the fixing portion 19a and is disposed between the wall surface la and the side surface 14e of the sill supporting member 10.

[0082] The threaded portion of the bolt 16a is passed through the round hole 19c of the first dam plate 19 and the round hole 14c of the sill side fixing piece 14a of the sill side supporting member 14. The nut 16b is screwed into the threaded portion of the bolt 16a to be temporarily fastened, thereby fastening the fixing portion 19a and the sill side fixing piece 14a to the lower surface 9b of the sill 9.

[0083] In the fifth step, the position of the sill 9 is adjusted. The fifth step is performed as follows.

[0084] For example, the position of the sill 9 in the width direction and the depth direction of the entrance 7 is adjusted with reference to the plumb bob provided in the shaft 1 in the first step. For example, the position of the sill 9 in the vertical direction is adjusted with reference to the height of the floor finish surface.

[0085] After the position of the sill 9 is adjusted, the sill 9 and the sill supporting member 10 are fixed. The nut 15b of the first engaging member 15 is fastened to fix the wall surface la and the wall side supporting member 13 of the sill supporting member 10. The nut 16b of the second engaging member 16 is fastened to fix the sill 9, the sill side supporting member 14 of the sill supporting member 10, and the first dam plate 19. The nut 17b of the third engaging member 17 is fastened to fix the wall side supporting member 13 and the sill side supporting member 14.

[0086] In the sixth step (second dam plate installation step), the second dam plate 20 is installed. The sixth step is performed as follows.

[0087] The second weir plate 20 is placed on the upper surface 13e of the sill support member 10 with one end 20a of the second weir plate 20 facing the wall surface la, the other end 20b of the second weir plate 20 facing the side opposite the wall surface la, and the second piece 20d of the second weir plate 20 extending upward from the first piece 20c. The one end 20a of the second weir plate 20 is abutted against the wall surface la.

[0088] Further, the sixth step is performed after the wall side support member 13 of the sill support member 10 is installed on the wall surface la, and can be performed before the third weir plate 21 is installed.

[0089] In the seventh step (third weir plate installation step), the third weir plate 21 is installed. The seventh step is performed as follows.

[0090] The one end 21a of the third weir plate 21 is placed on the upper surface 13e of the sill support member 10. The one end 21a of the third weir plate 21 is abutted against the upper surface 13e of the sill support member 10. The one end 21a of the third weir plate 21 is abutted against the side surface 20e of the second weir plate 20. The other end 21b of the third weir plate 21 is stood up against the first weir plate 19.

[0091] In the eighth step, the filling material 12 is filled between the sill 9 and the wall surface la of the shaft 1.

[0092] As described above, the landing sill device of the elevator is installed by the first step to the eighth step.

[0093] In the installation method of the landing sill device of the elevator in Embodiment 1, the gap 18 between the sill 9 and the wall surface la is blocked by the first weir plate 19, the second weir plate 20, and the third weir plate 21, the sill 9 is disposed at a lower portion of the entrance 7 that communicates the shaft 1 and the landing 2 and is supported by the sill support member 10 of the wall surface la of the shaft 1 fixed to the lower portion of the entrance 7, and the installation method of the landing sill device of the elevator includes the following steps: a first weir plate installation step of causing the first weir plate 19 to hang downward from the sill 9; a second weir plate installation step of placing the second weir plate 20 on the upper surface 13e of the sill support member 10, abutting the one end 20a of the second weir plate 20 against the wall surface la, and facing the other end 20b of the second weir plate 20 toward the side opposite the wall surface la; and a third weir plate installation step performed after the first weir plate installation step and the second weir plate installation step, of placing the one end 21a of the third weir plate 21 on the upper surface 13e of the sill support member 10 and abutting against the side surface 20e of the second weir plate 20 facing the side opposite the wall surface la, and standing up the other end 21b of the third weir plate 21 against the first weir plate 19.

[0094] Thus, even if the relative position of the sill 9 to the wall surface la changes, the state of the third weir plate 21 leaning against the first weir plate 19 to block the gap between the first weir plate 19 and the second weir plate 20 is maintained, and therefore it is not necessary to readjust the positions of the first weir plate 19, the second weir plate 20, and the third weir plate 21, and installation time can be reduced.

[0095] Further, when the filler material 12 is filled between the sill 9 and the wall surface la, even if the third weir plate 21 is pressed by the filler material 12, since one end 21a of the third weir plate 21 is pressed to the second weir plate 20 and the other end 21b of the third weir plate 21 is pressed to the first weir plate 19, it is not necessary to provide a member for fixing the third weir plate 21 to the first weir plate 19 and the second weir plate 20, manufacturing cost can be reduced, and installation time can be reduced.

[0096] Embodiment 2

[0097] Next, the hall sill device of the elevator in Embodiment 2 will be described. In addition, the same reference numerals are assigned to the same structures as those of Embodiment 1, and the description will be appropriately omitted hereafter.

[0098] In the hall sill device of the elevator in the above-described Embodiment 1, the wall-side support member 13, the first weir plate 19, and the second weir plate 20 are provided, but in the hall sill device of the elevator in Embodiment 2, a wall-side support member 22, a first weir plate 23, and a second weir plate 24 are provided instead of the wall-side support member 13, the first weir plate 19, and the second weir plate 20.

[0099] Use Figure 5 The wall-side support member 22, the first weir plate 23, and the second weir plate 24 will be described. Figure 5 is a right view of the hall sill device of the elevator in Embodiment 2. Figure 5 is a view corresponding to Figure 3 .

[0100] In the hall sill device of the elevator in Embodiment 2, the wall-side support member 22 is the same as the wall-side support member 13 of the hall sill device of the elevator in Embodiment 1 except that the shape of the upper surface 22e is different from the shape of the upper surface 13e of the hall sill device of the elevator in Embodiment 1.

[0101] The wall-side fixing piece 22a, the wall-side connecting piece 22b, the long hole 22c, the long hole 22d, and the upper surface 22e of the wall-side support member 22 correspond to the wall-side fixing piece 13a, the wall-side connecting piece 13b, the long hole 13c, the long hole 13d, and the upper surface 13e of the wall-side support member 13, respectively.

[0102] The upper surface 22e of the threshold support member 10 has a first upper surface 22f and a second upper surface 22g. The threshold support member 10 has a side surface 22h between the first upper surface 22f and the second upper surface 22g. The wall side support member 22 has the first upper surface 22f, the second upper surface 22g, and the side surface 22h. The first upper surface 22f is located on the side of the other end 24b of the second weir plate 24 toward the wall surface la. The first upper surface 22f is recessed downward more than the second upper surface 22g. The second upper surface 22g is located on the side of the other end 24b of the second weir plate 24 opposite the wall surface la. The second upper surface 22g is protruded upward more than the first upper surface 22f. The side surface 22h is located on the side of the other end 24b of the second weir plate 24 opposite the wall surface la. The side surface 22h faces the wall surface la. The wall surface la, the first upper surface 22f, and the side surface 22h form a recess 25.

[0103] The first weir plate 23 is hung downward from the threshold 9. The first weir plate 23 is disposed between the wall surface la and the side surface 9a of the threshold 9. The first weir plate 23 is along the side surface 9a of the threshold 9. The first weir plate 23 is abutted to the side surface 9a of the threshold 9. The first weir plate 23 is disposed between the wall surface la and the side surface 14e of the threshold support member 10. The first weir plate 23 is along the side surface 14e of the threshold support member 10. The first weir plate 23 is abutted to the side surface 14e of the threshold support member 10. A gap is left between the first weir plate 23 and the wall surface la.

[0104] The first weir plate 23 is mounted to the side surface 9a of the threshold 9. The first weir plate 23 is fixed to the side surface 9a of the threshold 9 by a fourth joint member 26. The first weir plate 23 is formed with a round hole 23a. The fourth joint member 26 has a bolt 26a and a nut 26b. The head of the bolt 26a is embedded in the groove portion 9d of the threshold 9. The threaded portion of the bolt 26a passes through the round hole 23a of the first weir plate 23. The nut 26b is screwed into the threaded portion of the bolt 26a, thereby fastening the first weir plate 23 to the side surface 9a of the threshold 9.

[0105] The second weir plate 24 is placed on the upper surface 22e of the threshold support member 10. The second weir plate 24 is abutted to the upper surface 22e of the threshold support member 10. The second weir plate 24 is placed on the first upper surface 22f of the threshold support member 10. The second weir plate 24 is abutted to the first upper surface 22f of the threshold support member 10. One end 24a of the second weir plate 24 is abutted to the wall surface la. The other end 24b of the second weir plate 24 faces the side opposite the wall surface la. The second weir plate 24 is embedded in the recess 25. The second weir plate 24 has a first piece 24c and a second piece 24d.

[0106] The first piece 24c is placed on the upper surface 22e of the threshold support member 10. The first piece 24c abuts against the upper surface 22e of the threshold support member 10. The first piece 24c is placed on the first upper surface 22f of the threshold support member 10. The first piece 24c abuts against the first upper surface 22f of the threshold support member 10. The first piece 24c is embedded in the recess 25. The first piece 24c extends longer than the wall hole portion 3a of the building structure wall 3 in the width direction of the entrance 7. The first piece 24c extends in the depth direction of the entrance 7. The first piece 24c has one end 24a, the other end 24b, and the upper surface 24e of the second weir plate 24.

[0107] The second piece 24d extends upward from between the one end 24a and the other end 24b of the first piece 24c. The second piece 24d protrudes from the upper surface 24e of the first piece 24c. The second piece 24d extends in the vertical direction. The second piece 24d has a side surface 24f toward the side opposite to the wall surface la. The second piece 24d is located on the side closer to the wall surface la than the other end 24b of the second weir plate 24. The second weir plate 24 is formed with one second piece 24d. The cross section of the second piece 24d perpendicular to the vertical direction is, for example, circular. The second piece 24d is, for example, a screw screwed into the second weir plate 24. The second piece 24d is, for example, a rivet hammered into the second weir plate 24. The cross section of the second piece 24d perpendicular to the vertical direction is, for example, polygonal. The second piece 24d extends upward by, for example, cutting a portion of the end 24b of the second weir plate 24 and standing it up.

[0108] The one end 21a of the third weir plate 21 is placed on the upper surface 24e of the second weir plate 24. The one end 21a of the third weir plate 21 abuts against the upper surface 24e of the second weir plate 24. The one end 21a of the third weir plate 21 abuts against the side surface 24f of the second weir plate 24. The other end 21b of the third weir plate 21 stands up against the first weir plate 23.

[0109] As described above, the first weir plate 23, the second weir plate 24, and the third weir plate 21 block the gap 18 between the threshold 9 and the wall surface la.

[0110] In the installation structure of the landing sill device of the elevator in Embodiment 2, there are provided: a sill 9 disposed at a lower portion of an entrance 7 that communicates between a hoistway 1 and a landing 2; a sill support member 10 that is fixed to an inner side wall surface la of the hoistway 1 below the entrance 7 and supports the sill 9; a first weir plate 23 that is hung downward from the sill 9; a second weir plate 24 that is placed on an upper surface 22e of the sill support member 10, one end 24a of the second weir plate 24 abutting against the wall surface la, and the other end 24b of the second weir plate 24 facing a side opposite to the wall surface la; and a third weir plate 21 whose one end 21a is placed on an upper surface 24e of the second weir plate 24 and abuts against a side surface 24f of the second weir plate 24 facing the side opposite to the wall surface la, and whose other end 21b stands up to abut against the first weir plate 23, the first weir plate 23, the second weir plate 24, and the third weir plate 21 blocking a gap 18 between the sill 9 and the wall surface la.

[0111] Thus, even if the relative positions of the sill 9 and the wall surface la change, the state in which the third weir plate 21 leans against the first weir plate 19 to block the gap between the first weir plate 23 and the second weir plate 24 is maintained, so it is not necessary to readjust the positions of the first weir plate 23, the second weir plate 24, and the third weir plate 21, and the installation time can be reduced.

[0112] Further, when the filler material 12 is filled between the sill 9 and the wall surface la, even if the third weir plate 21 is pressed by the filler material 12, since one end 21a of the third weir plate 21 is pressed against the second weir plate 24 and the other end 21b of the third weir plate 21 is pressed against the first weir plate 23, it is not necessary to provide a member for fixing the third weir plate 21 to the first weir plate 23 and the second weir plate 24, the manufacturing cost can be reduced, and the installation time can be reduced.

[0113] Further, since the second weir plate 23 is placed and supported on the upper surface 22e of the sill support member 10, the deflection of the second weir plate 24 that occurs when a vertical load acts on the second weir plate 24 can be suppressed.

[0114] Further, even if the gap 18 between the sill 9 and the wall surface la becomes large, since the second weir plate 24 is installed between the wall surface la and the third weir plate 21, the inclination of the third weir plate 21 can be maintained within a desired range, and the deflection of the third weir plate 21 that occurs when a vertical load acts on the third weir plate 21 can be suppressed.

[0115] In the installation structure of the landing sill device of the elevator in Embodiment 2, the first weir plate 23 is along a side surface 14e of the sill support member 10 that faces the wall surface la side.

[0116] Thus, when the filler material 12 is filled between the sill 9 and the wall surface la, even if the first weir plate 23 is pressed by the filler material 12 toward the sill support member 10 side, the first weir plate 23 is restrained from being deflected by abutting against the side surface 14e of the sill support member 10, so there is no need to provide a member for fixing the lower portion of the first weir plate 23, manufacturing cost can be reduced, and installation time can be shortened.

[0117] In the installation structure of the landing sill device of the elevator in Embodiment 2, the second weir plate 24 has a first piece 24c having one end 24a, the other end 24b, and the upper surface 24e of the second weir plate 24, and a second piece 24d extending upward from between the one end 24a and the other end 24b of the first piece 24c and having the side surface 24f of the second weir plate 24, the one end 21a of the third weir plate 21 is placed on the upper surface 24e of the second weir plate 24 and abuts against the side surface 24f of the second weir plate 24.

[0118] Thus, the one end 21a of the third weir plate 21 can be restrained from being separated from the other end 24b of the second weir plate 24, there is no need to provide a member for fixing the one end 21a of the third weir plate 21, manufacturing cost can be reduced, and installation time can be shortened.

[0119] Further, even if the relative angle of the side surface 9a of the sill 9 and the wall surface la in the horizontal direction changes, the one end 21a of the third weir plate 21 rotates along the upper surface 24e and the side surface 24f of the second weir plate 24, and maintains the state of blocking the gap between the second weir plate 24 and the third weir plate 21, so there is no need to readjust the positions of the first weir plate 23, the second weir plate 24, and the third weir plate 21, and installation time can be shortened.

[0120] In the installation structure of the landing sill device of the elevator in Embodiment 2, the upper surface 22e of the sill support member 10 has a first upper surface 22f and a second upper surface 22g, and has a side surface 22h between the first upper surface 22f and the second upper surface 22g, the first upper surface 22f is located on the side of the other end 24b of the second weir plate 24 to the wall surface la and is recessed downward more than the second upper surface 22g, the second upper surface 22g is located on the side opposite to the wall surface la from the other end 24b of the second weir plate 24 and is protruded upward more than the first upper surface 22f, and the side surface 22h is located on the side opposite to the wall surface la from the other end 24b of the second weir plate 24 and faces the wall surface la side, the wall surface la and the first upper surface 22f and the side surface 22h of the sill support member 10 form a recess 25, and the second weir plate 24 is embedded in the recess 25.

[0121] Thus, the position of the second weir plate 24 can be inhibited from shifting in the depth direction of the entrance 7, and therefore it is not necessary to provide a member for fixing the second weir plate 24, manufacturing costs can be reduced, and installation time can be shortened.

[0122] In addition, the side surface 14e of the threshold support member 10 is preferably arranged without a step difference from the side surface 9a of the threshold 9, but can be arranged with a step difference from the side surface 9a of the threshold 9. In this case, for example, the first weir plate 23 is bent along the side surface 14e of the threshold support member 10.

[0123] Embodiment 3

[0124] Next, the landing threshold device of the elevator in Embodiment 3 will be described. In addition, the same reference numerals are assigned to the same structures as those of Embodiment 1, and the description will be appropriately omitted hereafter.

[0127] In the landing threshold device of the elevator in Embodiment 3, the wall side support member 27 is the same as the wall side support member 13 of the landing threshold device of the elevator in Embodiment 1 except that the shape of the upper surface 27e is different from the shape of the upper surface 13e of the landing threshold device of the elevator in Embodiment 1.

[0128] The wall side fixing piece 27a, the wall side connecting piece 27b, the long hole 27c, the long hole 27d, and the upper surface 27e of the wall side support member 27 correspond to the wall side fixing piece 13a, the wall side connecting piece 13b, the long hole 13c, the long hole 13d, and the upper surface 13e of the wall side support member 13, respectively.

[0131] The hook portion 28a is hooked to the groove portion 9d of the threshold 9. The hook portion 28a is placed in the groove portion 9d of the threshold 9. The hook portion 28a extends from the groove portion 9d of the threshold 9 to the wall face 1a side. The hook portion 28a extends in the width direction of the entrance 7. The hook portion 28a extends in the depth direction of the entrance 7. In addition, the hook portion 28a extends in the width direction of the entrance 7 to the same length as the plug portion 28b, but can extend shorter than the plug portion 28b or longer than the plug portion 28b.

[0132] The plug portion 28b extends downward from the wall face 1a side end of the hook portion 28a. The plug portion 28b extends in the vertical direction. The plug portion 28b extends longer than the wall hole portion 3a of the building structure wall 3 in the width direction of the entrance 7. The plug portion 28b is disposed between the wall face 1a and the side surface 9a of the threshold 9. The plug portion 28b follows along the side surface 9a of the threshold 9. The plug portion 28b abuts against the side surface 9a of the threshold 9. The plug portion 28b is disposed between the wall face 1a and the side surface 14e of the threshold support member 10. The plug portion 28b follows along the side surface 14e of the threshold support member 10. The plug portion 28b abuts against the side surface 14e of the threshold support member 10. A gap is left between the plug portion 28b and the wall face 1a.

[0135] As described above, the first weir plate 28, the second weir plate 29, and the third weir plate 21 block the gap 18 between the sill 9 and the wall surface la.

[0136] In the installation structure of the landing sill device of the elevator in Embodiment 3, there are provided: the sill 9 disposed at the lower portion of the entrance 7 that communicates the hoistway 1 with the landing 2; the sill support member 10 fixed to the wall surface la on the inner side of the hoistway 1 below the entrance 7 and supporting the sill 9; the first weir plate 28 hanging downward from the sill 9; the second weir plate 29 placed on the upper surface 27e of the sill support member 10, one end 29a of the second weir plate 29 abutting against the wall surface la, and the other end 29b of the second weir plate 29 facing the side opposite to the wall surface la; and the third weir plate 21 having one end 21a placed on the upper surface 27e of the sill support member 10 and abutting against the side surface 27h of the sill support member 10 facing the side opposite to the wall surface la, and the other end 21b of the third weir plate 21 standing up against the first weir plate 28, the first weir plate 28, the second weir plate 29, and the third weir plate 21 blocking the gap 18 between the sill 9 and the wall surface la.

[0137] Thus, even if the relative position of the sill 9 to the wall surface la is changed, the state in which the third weir plate 21 leans against the first weir plate 28 to block the gap between the first weir plate 28 and the second weir plate 29 is maintained, and therefore it is not necessary to readjust the positions of the first weir plate 28, the second weir plate 29, and the third weir plate 21, and the installation time can be reduced.

[0138] Further, when the filler material 12 is filled between the sill 9 and the wall surface la, even if the third weir plate 21 is pressed by the filler material 12, since one end 21a of the third weir plate 21 is pressed to the sill support member 10 and the other end 21b of the third weir plate 21 is pressed to the first weir plate 28, it is not necessary to provide a member for fixing the third weir plate 21 to the sill support member 10 and the first weir plate 28, the manufacturing cost can be reduced, and the installation time can be reduced.

[0139] Further, since the second weir plate 29 is placed and supported on the upper surface 27e of the sill support member 10, the deflection of the second weir plate 29 when vertical load acts on the second weir plate 29 can be suppressed.

[0140] Further, even if the gap 18 between the sill 9 and the wall surface la becomes large, since the second weir plate 29 is installed between the wall surface la and the third weir plate 21, the inclination of the third weir plate 21 can be maintained within a desired range, and the deflection of the third weir plate 21 when vertical load acts on the third weir plate 21 can be suppressed.

[0141] In the installation structure of the landing sill device of the elevator in Embodiment 3, the sill 9 is formed with a groove portion 9d extending in the width direction of the entrance 7 on the side surface 9a toward the landing 2 side, and the first weir plate 28 is hooked to the groove portion 9d of the sill 9 to hang downward.

[0142] Thus, it is not necessary to provide a member for hanging the first weir plate 28 downward with respect to the sill 9, the manufacturing cost can be reduced, and the installation time can be reduced.

[0143] In the installation structure of the landing sill device of the elevator in Embodiment 3, the first weir plate 28 is along the side surface 14e of the sill support member 10 toward the wall surface la side.

[0144] Thus, when the filler material 12 is filled between the sill 9 and the wall surface la, even if the first weir plate 28 is pressed by the filler material 12 toward the sill support member 10 side, the first weir plate 28 will abut against the side surface 14e of the sill support member 10 to suppress the deflection of the first weir plate 28, and therefore it is not necessary to provide a member for fixing the lower portion of the first weir plate 28, the manufacturing cost can be reduced, and the installation time can be reduced.

[0145] In the installation structure of the landing sill device of the elevator in Embodiment 3, the upper surface 27e of the sill support member 10 has a first upper surface 27f and a second upper surface 27g, and the sill support member 10 has a side surface 27h between the first upper surface 27f and the second upper surface 27g, the first upper surface 27f is located at a position closer to the wall surface 1a than the other end 29b of the second weir plate 29 and protrudes upward more than the second upper surface 27g, the second upper surface 27g is located at a position from the other end 29b of the second weir plate 29 to the side opposite to the wall surface 1a and is recessed downward more than the first upper surface 27f, the side surface 27h is located at a position closer to the wall surface 1a than the other end 29b of the second weir plate 29, the second weir plate 29 is placed on the first upper surface 27f of the sill support member 10, one end 21a of the third weir plate 21 is placed on the second upper surface 27g of the sill support member 10 and abuts against the side surface 27h of the sill support member 10, and the one end 21a and the other end 21b of the third weir plate 21 abut against the second weir plate 29.

[0146] Thus, even if the relative position of the sill 9 to the wall surface 1a changes, the state in which the third weir plate 21 leans against the first weir plate 28 side to block the gap between the first weir plate 28 and the second weir plate 29 is maintained, so it is not necessary to readjust the positions of the first weir plate 28, the second weir plate 29, and the third weir plate 21, and the installation time can be reduced.

[0147] Further, even if the relative position of the sill 9 to the wall surface 1a changes, the state in which the second weir plate 29 leans against the third weir plate 21 side to block the gap between the second weir plate 29 and the third weir plate 21 is maintained, so it is not necessary to readjust the positions of the first weir plate 28, the second weir plate 29, and the third weir plate 21, and the installation time can be reduced.

[0148] Further, the side surface 14e of the sill support member 10 is preferably arranged without a step difference from the side surface 9a of the sill 9, but can be arranged with a step difference from the side surface 9a of the sill 9. In this case, for example, it is sufficient to bend the first weir plate 28 along the side surface 14e of the sill support member 10.
