DETAILED DESCRIPTION

[0030] A mode for carrying out the object of the present disclosure will be described with reference to the drawings. In the drawings, the same or corresponding portions are denoted by the same reference numerals, and repeated explanation is appropriately simplified or omitted. Furthermore, the object of the present disclosure is not limited to the following embodiments, and any modification of the constituent elements of the embodiments or omission of the constituent elements of the embodiments can be made within the scope of the gist of the present disclosure.

[0031] Embodiment 1

[0032] Figure 1 is a longitudinal sectional view showing a state in which the installation template device of the elevator of Embodiment 1 is provided at the top of the shaft. In the drawing, a shaft 102 is provided at a building 101. A landing entrance 103 is provided at each landing of the building 101. At each landing, a space of the shaft 102 is opened to the landing through the landing entrance 103. A lateral width direction of the landing entrance 103 of each landing is a direction parallel to a width direction of the shaft 102.

[0033] A plurality of hoisting beams 104 as fixed members are fixed to the top of the hoistway 102. Each hoisting beam 104 is arranged horizontally and parallel to each other. In the present embodiment, each hoisting beam 104 is arranged in the width direction of the hoistway 102. In addition, in the present embodiment, two hoisting beams 104 are arranged separately from each other in the depth direction of the hoistway 102. The depth direction of the hoistway 102 is a horizontal direction perpendicular to the width direction of the hoistway 102. In the present embodiment, a H-shaped steel is used as the hoisting beam 104.

[0034] When installing an elevator in the hoistway 102, in order to perform positioning of objects provided in the hoistway 102, the installation template device 1 is installed to the plurality of hoisting beams 104. In the present embodiment, a landing sill not shown that is provided at the lower part of each of the landing entrances 103 of the floors and a pair of car guide rails not shown that are provided to face each other in the width direction of the hoistway 102 become positioning objects. The installation template device 1 is arranged at the top of the hoistway 102 by being installed to each hoisting beam 104.

[0035] A plurality of plumb lines 3 that respectively suspend a weight 2 are connected to the installation template device 1. By this, each plumb line 3 is pulled in the vertical direction from the installation template device 1 in the hoistway 102. As the plumb line 3, for example, a piano wire is used. The position of each plumb line 3 when the hoistway 102 is viewed from above is set to a position that becomes a positioning reference of each object in the hoistway 102. By this, each plumb line 3 becomes a positioning reference of each object.

[0036] In the present embodiment, a pair of plumb lines 3 that become a positioning reference of the landing sill among the plurality of plumb lines 3 are pulled in the hoistway 102 as a pair of landing sill plumb lines 3a. In addition, in the present embodiment, a pair of plumb lines 3 that become a positioning reference of the pair of car guide rails among the plurality of plumb lines 3 are pulled in the hoistway 102 as a pair of car guide rail plumb lines 3b.

[0037] Figure 2 is a perspective view of the installation template device 1 that represents Figure 1 The installation template device 1 has a plurality of support members 4, a plurality of ruler members 5, a plurality of support mounts 6, and a plurality of ruler mounts 7.

[0038] Each support member 4 is placed on each hoisting beam 104 across the plurality of hoisting beams 104. In the present embodiment, two support members 4 are placed on each hoisting beam 104 across the two hoisting beams 104. Each support member 4 is arranged in the depth direction of the hoistway 102. Each support member 4 is arranged separately from each other in the width direction of the hoistway 102. Each support member 4 is installed to each hoisting beam 104 by the plurality of support mounts 6.

[0039] Each ruler member 5 is placed across each support member 4. Each ruler member 5 is arranged along the width direction of the hoistway 102. A plurality of ruler members 5 are arranged separately from each other in the depth direction of the hoistway 102. Each ruler member 5 is attached to each support member 4 by a plurality of ruler attachment members 7.

[0040] In the present embodiment, two ruler members 5 are attached to each support member 4. In the present embodiment, one of the two ruler members 5 is a landing sill ruler member 5a, and the other is a car guide rail ruler member 5b. In the present embodiment, when the hoistway 102 is viewed from above, the landing sill ruler member 5a is arranged closer to the landing entrance 103 than the car guide rail ruler member 5b. In the present embodiment, a pair of landing sill plumb lines 3a is connected to the landing sill ruler member 5a, and a pair of car guide rail plumb lines 3b is connected to the car guide rail ruler member 5b.

[0041] Each ruler member 5 has a ruler member body 51, a plurality of link members 52, and a pair of connection members 53. The plurality of link members 52 and the pair of connection members 53 are attached to the ruler member body 51.

[0042] The ruler member body 51 has a plurality of ruler blocks 54. The plurality of ruler blocks 54 are continuously connected to each other in the length direction of the ruler member 5 in a detachable manner. Each ruler block 54 is arranged along the length direction of the ruler member 5. The length of the ruler member body 51 can be adjusted by adjusting the number of the ruler blocks 54.

[0043] In each ruler member 5, one of the plurality of ruler blocks 54 is a base ruler block 54a, and the ruler blocks 54 other than the base ruler block 54a are extension ruler blocks 54b. The length of the base ruler block 54a is longer than the length of the extension ruler block 54b. The lengths of the extension ruler blocks 54b are the same as each other. The length of the ruler member body 51 is adjusted by adjusting the number of the extension ruler blocks 54b.

[0044] In the present embodiment, the length of the ruler member body 51 of the landing sill ruler member 5a is shorter than the length of the ruler member body 51 of the car guide rail ruler member 5b.

[0045] In the ruler member body 51 of the landing sill ruler member 5a, one extension ruler block 54b is connected to each of the both end portions of the base ruler block 54a. Thus, in the ruler member body 51 of the landing sill ruler member 5a, three ruler blocks 54 are continuously connected.

[0046] On the other hand, in the gauge member main body 51 of the car guide rail gauge member 5b, two extended gauge blocks 54b are continuously joined at both end portions of the base gauge block 54a. Thus, in the gauge member main body 51 of the car guide rail gauge member 5b, five gauge blocks 54 are continuously joined.

[0047] Each of the link members 52 joins two gauge blocks 54 adjacent to each other. Each of the link members 52 is installed to the gauge member main body 51 in a state of covering the boundaries of the two gauge blocks 54 adjacent to each other.

[0048] One of the pair of the link members 53 is installed to the extended gauge block 54b at one end portion of the gauge member main body 51. The other of the pair of the link members 53 is installed to the extended gauge block 54b at the other end portion of the gauge member main body 51. The pair of the plumb lines 3 is connected to each of the link members 53. In addition, in a case where the base gauge block 54a is located at the end portion of the gauge member main body 51, the link member 53 is installed to the base gauge block 54a.

[0049] In the landing sill gauge member 5a, the pair of the landing sill plumb lines 3a is connected to the pair of the link members 53, respectively. In the car guide rail gauge member 5b, the pair of the car guide rail plumb lines 3b is connected to the pair of the link members 53, respectively.

[0050] Figure 3 is a perspective view of the base gauge block 54a included in each of the gauge members 5 of Figure 2 Figure 4 is a perspective view of the extended gauge block 54b included in each of the gauge members 5 of Figure 2 The base gauge block 54a and the extended gauge block 54b each, that is, each of the gauge blocks 54 has a back plate portion 541 and a pair of side plate portions 542.

[0051] The back plate portion 541 and the pair of the side plate portions 542 are arranged along the length direction of the gauge member 5, respectively. The side plate portions 542 are provided at both edge portions of the back plate portion 541, respectively. The pair of the side plate portions 542 faces each other across a space in the width direction of the back plate portion 541. Thus, the cross-sectional shape of the gauge block 54 in a plane perpendicular to the length direction of the gauge member 5 becomes a C shape by the back plate portion 541 and the pair of the side plate portions 542. In each of the gauge blocks 54, an open portion along the length direction of the gauge member 5 is formed between the edge portions of the pair of the side plate portions 542. Each of the gauge blocks 54 is arranged in a manner that the back plate portion 541 faces upward and the open portion of the gauge block 54 faces downward. The width direction of each of the gauge blocks 54 coincides with the width direction of the back plate portion 541, and the thickness direction of each of the gauge blocks 54 coincides with the thickness direction of the back plate portion 541. ​

[0052] At both end portions of each ruler block 54, a connection-use mounting hole 56 is provided to the back plate portion 541, and a coupling-use mounting hole 57 is provided to each of the pair of side plate portions 542. The connection-use mounting hole 56 is a through hole that penetrates the back plate portion 541 in the thickness direction of the back plate portion 541. The coupling-use mounting hole 57 is a through hole that penetrates the side plate portion 542 in the thickness direction of the side plate portion 542. In the present embodiment, the coupling-use mounting hole 57 is a threaded hole.

[0053] Figure 5 is an enlarged perspective view of the ruler block main body 51 and the connection member 53 in the landing sill ruler member 5a. Figure 2 Figure 6 is an enlarged perspective view of a state in which the extension ruler block 54b is detached from the base ruler block 54a. Figure 5 Figure 7 is an enlarged perspective view of an end portion of the base ruler block 54a. Figure 6

[0054] Here, the structure of the car guide rail ruler member 5b is different from the structure of the landing sill ruler member 5a only in the number of extension ruler blocks 54b. Therefore, the structure common to each of the landing sill ruler member 5a and the car guide rail ruler member 5b will be described as the structure of the ruler member 5. In addition, the structure of the base ruler block 54a is the same as the structure of the extension ruler block 54b except that the length of the base ruler block 54a is longer than the length of the extension ruler block 54b. Therefore, hereafter, the base ruler block 54a and the extension ruler block 54b will be described as the ruler block 54 except for cases where it is necessary to distinguish the base ruler block 54a and the extension ruler block 54b.

[0055] In each ruler member 5, at the boundary between two ruler blocks 54 adjacent to each other, as shown in Figure 5 , the end faces of the two ruler blocks 54 are in contact with each other. That is, at the boundary between two ruler blocks 54 adjacent to each other, the end faces of the back plate portions 541 of the two ruler blocks 54 are in contact with each other, and the end faces of the side plate portions 542 of the two ruler blocks 54 are in contact with each other. Thus, in each ruler member 5, a plurality of ruler blocks 54 are arranged in a straight line.

[0056] In each ruler member 5, at the boundary between two ruler blocks 54 adjacent to each other, a plurality of fitting structure portions 58 are provided. As shown in Figure 6 , each fitting structure portion 58 has a protrusion portion 581 and a recess portion 582. The protrusion portion 581 protrudes from one of the two ruler blocks 54 adjacent to each other. The recess portion 582 is formed in the other of the two ruler blocks 54 adjacent to each other. In each fitting structure portion 58, in a state in which the two ruler blocks 54 are coupled to each other, the protrusion portion 581 is fitted into the recess portion 582.​​​

[0057] The fitting structure 58 is respectively provided at the boundary between the back plate portion 541 of two adjacent ruler blocks 54 and the boundary between the side plate portion 542 of two adjacent ruler blocks 54.

[0058] Here, in the main body 51 of the ruler component, the width direction of the ruler block 54 is defined as the X direction, and the thickness direction of the ruler block 54 is defined as the Y direction. The length direction of the ruler component 5 is the Z direction, which is perpendicular to both the X and Y directions. In this case, when the two ruler blocks 54 are connected to each other, the fitting structure 58 provided at the boundaries between the back plate portions 541 prevents the two ruler blocks 54 from shifting position relative to each other in the X direction. Furthermore, when the two ruler blocks 54 are connected to each other, the fitting structure 58 provided at the boundaries between the side plate portions 542 prevents the two ruler blocks 54 from shifting position relative to each other in the Y direction.

[0059] Figure 8 It means Figure 2 An enlarged perspective view of the connector 52 in the gauge component 5a of the station sill. Figure 9 It means Figure 8 An exploded perspective view of the connecting member 52 detached from the main body 51 of the gauge component. The structure of each connecting member 52 is the same in the gauge component 5a for the landing sill and the gauge component 5b for the car guide rail. Each connecting member 52 has a connecting member body 521, a first fastening bolt 522, and a second fastening bolt 523.

[0060] The connecting body 521 is configured to span the boundaries of two adjacent ruler blocks 54. The connecting body 521 is embedded in the ruler component body 51 in a state that covers the boundaries of the two adjacent ruler blocks 54. When the connecting body 521 is embedded in the ruler component body 51, the length direction of the connecting body 521 is consistent with the length direction of the ruler component 5.

[0061] The connector body 521 has a first overlapping plate portion 521a and a pair of second overlapping plate portions 521b. The first overlapping plate portion 521a is a plate-shaped portion along the length direction of the connector body 521. The second overlapping plate portions 521b are respectively provided at the two edges of the first overlapping plate portion 521a. The pair of second overlapping plate portions 521b are opposite to each other in the width direction of the first overlapping plate portion 521a. Thus, the cross-sectional shape of the connector body 521 in a plane perpendicular to the length direction of the connector body 521 is U-shaped by the first overlapping plate portion 521a and the pair of second overlapping plate portions 521b. In this embodiment, the connector body 521 is formed by bending a raw material plate.

[0062] In the main body 521 of the connector, each of the pair of second overlapping plate portions 521b is provided with a first through hole 524 and a second through hole 525. The first through hole 524 and the second through hole 525 are through holes that penetrate the second overlapping plate portion 521b.

[0063] The first through hole 524 is provided at one end of the connecting body 521 along its length. The second through hole 525 is provided at the other end of the connecting body 521 along its length. When the connecting body 521 covers the boundaries of the two ruler blocks 54 and is embedded in the ruler component body 51, the first through hole 524 overlaps with the mounting hole 57 for connecting one ruler block 54, and the second through hole 525 overlaps with the mounting hole 57 for connecting the other ruler block 54.

[0064] The first fastening bolt 522 is the first fastening component that fastens the connecting body 521 to one of the two ruler blocks 54. The connecting body 521 is fastened to a ruler block 54 by screwing the first fastening bolt 522, which passes through the first through hole 524, into the connecting mounting hole 57 of a ruler block 54. In this embodiment, the connecting body 521 is fastened to a ruler block 54 only by passing the first fastening bolt 522, which is provided in either of the two first through holes 524 of the connecting body 521.

[0065] The second fastening bolt 523 is a second fastening component that fastens the connecting body 521 to the other of the two gauge blocks 54. The connecting body 521 is fastened to the other gauge block 54 by screwing the second fastening bolt 523, which passes through the second through hole 525, into the connecting mounting hole 57 of the other gauge block 54. In this embodiment, the connecting body 521 is fastened to the other gauge block 54 only by passing the second fastening bolt 523, which is provided in either of the two second through holes 525 of the connecting body 521.

[0066] With the two ruler blocks 54 connected to each other by the connecting member 52, separation of the two ruler blocks 54 in the Z direction is prevented. As a result, in each fitting structure portion 58, the protrusion 581 is maintained in the state of being embedded in the recess 582.

[0067] Figure 10 It means Figure 2 A perspective view of connector 53. Figure 11 It means Figure 10 An enlarged perspective view of the connector 53 installed on the main body 51 of the ruler component. Additionally, in Figure 11 In the image, a portion of the connector 53 is omitted. Each connector 53 has a protruding part 531 and a connector body 532.

[0068] The protruding member 531 is a plate-shaped member arranged along the length direction of the ruler member 5. The protruding member 531 is attached to the ruler block 54 at the end of the ruler member main body 51 in a state of protruding in the length direction of the ruler member 5 in a detachable manner. In the present embodiment, the protruding member 531 is attached to the extension ruler block 54b. A part of the protruding member 531 is inserted into the inside of the ruler block 54 at the end of the ruler member main body 51. The remaining part of the protruding member 531 protrudes from the ruler block 54 at the end of the ruler member main body 51.

[0069] As shown in FIG. 5, a threaded hole 533 and a plurality of adjustment holes 534 are provided in the protruding member 531. The threaded hole 533 is provided in the part of the protruding member 531 inserted into the inside of the ruler block 54. The plurality of adjustment holes 534 are provided in the part of the protruding member 531 protruding from the ruler block 54. Figure 10

[0070] Each of the adjustment holes 534 is a through hole passing through the protruding member 531. The plurality of adjustment holes 534 are provided in the protruding member 531 at intervals from each other in the length direction of the ruler member 5. The interval of the plurality of adjustment holes 534 is shorter than the dimension of the extension ruler block 54b in the length direction of the ruler member 5. In the present embodiment, the plurality of adjustment holes 534 are arranged at equal intervals in the length direction of the ruler member main body 51. In the present embodiment, the distance between the centers of two adjustment holes 534 adjacent to each other is set to several tens of mm.

[0071] The protruding member 531 is attached to the ruler block 54 at the end of the ruler member main body 51 by screwing the fastening bolt 530 passing through the connecting member of the ruler block 54 into the threaded hole 533 of the protruding member 531. Thus, the protruding member 531 is detachable with respect to the ruler block 54.

[0072] The connecting member main body 532 is attached to the protruding member 531 in a detachable manner. The connecting member main body 532 is attached to the protruding member 531 in a state of being selectively arranged in any of the plurality of adjustment holes 534. The position of the connecting member main body 532 with respect to the protruding member 531 is adjusted by changing the adjustment hole 534 of the plurality of adjustment holes 534 in which the connecting member main body 532 is arranged. The distance from the end of the ruler member main body 51 to the connecting member main body 532 is adjusted by adjusting the position of the connecting member main body 532 with respect to the protruding member 531.

[0073] ​The plumb line 3 is connected to the connecting member body 532. The connection position of the plumb line 3 with respect to the connecting member 53 is adjusted by adjustment of the position of the connecting member body 532 with respect to the protruding member 531. In each of the scale members 5, the distance between a pair of the plumb lines 3 is adjusted by adjustment of the number of the extension scale blocks 54b and adjustment of the position of the connecting member body 532 with respect to the protruding member 531 in each of the connecting members 53.

[0074] As shown in Figure 10 , the connecting member body 532 has a mounting bolt 532a, a mounting nut 532b, and a connecting nut 532c.

[0075] The threaded portion of the mounting bolt 532a passes through any of a plurality of adjustment holes 534. The threaded portion of the mounting bolt 532a is screwed into the mounting nut 532b. The mounting bolt 532a is mounted to the protruding member 531 by fastening the protruding member 531 between the head of the mounting bolt 532a and the mounting nut 532b. Thus, the connecting member body 532 can be attached to or detached from the protruding member 531.

[0076] The connecting nut 532c is screwed into the threaded portion of the mounting bolt 532a mounted to the protruding member 531. In the present embodiment, a wing nut is used as the connecting nut 532c. The plumb line 3 is connected to the connecting member body 532 by fastening the connecting nut 532c to the mounting nut 532b.

[0077] As shown in Figure 2 , each of the support members 4 has a support member body 41 and a link member 42. The link member 42 is mounted to the support member body 41.

[0078] The support member body 41 has a plurality of support blocks 43. The plurality of support blocks 43 are continuously connected to each other in the length direction of the support member 4 in an attachable and detachable manner. Each of the support blocks 43 is arranged along the length direction of the support member 4. The length of the support member body 41 can be adjusted by adjustment of the number of the support blocks 43.

[0079] In each of the support members 4, one of the plurality of support blocks 43 is a base support block 43a, and the support blocks 43 other than the base support block 43a are extension support blocks 43b. The length of the base support block 43a is longer than the length of the extension support block 43b.

[0080] In the present embodiment, the length of each support member 4 is set to the same length as each other. In addition, in the present embodiment, one extension support block 43b is joined to one base support block 43a in each support member 4. The base support block 43a has the same structure as the base ruler block 54a, and the extension support block 43b has the same structure as the extension ruler block 54b. Each support member 4 is arranged so that the open portion of the support block 43 faces downward.

[0081] The link member 42 links two support blocks 43 adjacent to each other. The link member 42 is attached to the support member body 41 in a state of covering the boundary of the two support blocks 43 adjacent to each other. The structure of the link member 42 in the support member 4 is the same as the structure of the link member 52 in the ruler member 5.

[0082] As shown in Figure 2 , each support mounting member 6 is arranged at a position where the support member body 41 intersects the crane beam 104. Each support mounting member 6 is attached to the support member body 41 in a detachable manner. Each support mounting member 6 attaches the support member 4 to the crane beam 104 at a position where the support member body 41 intersects the crane beam 104.

[0083] Figure 12 is an enlarged side view showing a state in which the support mounting member 6 of Figure 2 attaches the support member 4 to the crane beam 104. Figure 13 is an enlarged side view showing a state in which the support mounting member 6 of Figure 12 attaches the support member 4 to the crane beam 104.

[0084] As shown in Figure 12 , the support pressing member 61 has a hooking portion 611, a holding portion 612, and a connecting portion 613. The shape of the support pressing member 61 becomes Z-shaped by the hooking portion 611, the holding portion 612, and the connecting portion 613. The support pressing member 61 is formed by bending one raw material plate.

[0085] The support pressing member 61 is arranged in a state in which the hooking portion 611 overlaps the lower surface of the upper flange of the crane beam 104, which is an H-shaped steel. Thereby, the hooking portion 611 becomes a state of sandwiching a part of the crane beam 104 between the support member 4. That is, the support pressing member 61 is arranged in a state of sandwiching a part of the crane beam 104 between the support member 4 and the hooking portion 611.

[0086] The holding portion 612 is arranged inside the support block 43. In addition, the holding portion 612 is held to the support block 43 by the holding structure 62. In the present embodiment, the holding portion 612 is held to the base support block 43a.

[0087] The connecting part 613 connects the hook part 611 disposed on the outside of the support block 43 and the retaining part 612 disposed on the inside of the support block 43. Thus, the connecting part 613 reaches the retaining part 612 from the hook part 611 through the opening of the support block 43.

[0088] The retaining structure 62 has a sliding component 621 and a supporting fastening bolt 622.

[0089] The sliding member 621 is mounted on the support member 4 in a manner that allows it to slide along the length of the support member 4. For example... Figure 13 As shown, the sliding member 621 has a C-shaped cross-section in a plane perpendicular to the length direction of the support member 4. The sliding member 621 is mounted on the support member 4 with the support block 43 passing through the inside of the sliding member 621.

[0090] like Figure 12 As shown, the support fastening bolt 622 is a support fastening component installed on the sliding component 621. The threaded portion of the support fastening bolt 622 is screwed into the threaded hole provided in the sliding component 621. The screwing amount of the support fastening bolt 622 relative to the sliding component 621 is adjusted by rotating the support fastening bolt 622. The retaining portion 612 of the support pressing component 61 is held in place on the support component 4 by being pressed against the support component 4 by the support fastening bolt 622.

[0091] The support fastening bolt 622 is inserted into the inside of the support block 43 through the opening of the sliding member 621. The support fastening bolt 622 presses the retaining part 612 against the support member 4 on the inside of the support block 43.

[0092] The retaining part 612 is an elastic part capable of elastic deformation. Therefore, the retaining part 612 functions as a leaf spring. The retaining part 612 elastically deforms between the supporting fastening bolt 622 and the supporting member 4. The amount of elastic deformation of the retaining part 612 when pressed against the supporting member 4 is adjusted by adjusting the amount of screwing of the supporting fastening bolt 622 relative to the sliding member 621.

[0093] With the retaining part 612 in a state of elastic deformation between the supporting fastening bolt 622 and the supporting part 4, the supporting pressing member 61 presses a portion of the lifting beam 104 against the supporting part 4 via the hook part 611. Thus, a portion of the lifting beam 104 is held between the hook part 611 and the supporting part 4. By holding a portion of the lifting beam 104 between the hook part 611 and the supporting part 4, the supporting part 4 is installed on the lifting beam 104. The holding force when holding a portion of the lifting beam 104 between the hook part 611 and the supporting part 4 is adjusted by adjusting the amount of elastic deformation of the retaining part 612 when pressed against the supporting part 4.

[0094] As shown in Figure 2 FIG. 7, each ruler mounting member 7 is arranged at a position where the ruler member 5 intersects the support member 4. Each ruler mounting member 7 is detachably mounted to the support member main body 41. Each ruler mounting member 7 mounts the ruler member 5 to the support member 4 at a position where the ruler member 5 intersects the support member 4.

[0095] Figure 14 is an enlarged perspective view of the ruler mounting member 7 of Figure 2 FIG. 7. Each ruler mounting member 7 has a support mounting structure 71, a ruler pressing member 72, and a ruler coupling bolt 73.

[0096] The support mounting structure 71 is detachably mounted to the support member 4. The support mounting structure 71 has a mounting member 711, a clamping plate 712, and a fastening bolt 713.

[0097] The mounting member 711 has a main body portion 711a which is fitted into the support member 4, and a pair of receiving plate portions 711b which protrude in opposite directions from the main body portion 711a. The mounting member 711 is mounted to the support member 4 in a state in which the main body portion 711a is fitted into the support member 4.

[0098] The clamping plate 712 is arranged inside the support block 43 of the support member 4. A threaded hole is provided in the clamping plate 712. The fastening bolt 713 which passes through the through hole provided in the main body portion 711a is screwed into the threaded hole of the clamping plate 712. In a state in which the main body portion 711a is fitted into the support member 4, by fastening the fastening bolt 713 to the threaded hole of the clamping plate 712, a portion of the support block 43 is held between the main body portion 711a and the clamping plate 712. By holding the portion of the support block 43 between the main body portion 711a and the clamping plate 712, the support mounting structure 71 is detachably mounted to the support member 4.

[0099] The ruler coupling bolt 73 is a ruler coupling member which mounts the ruler pressing member 72 to the support mounting structure 71. The ruler pressing member 72 is fastened to the support mounting structure 71 by the ruler coupling bolt 73. Thus, the ruler pressing member 72 is detachably mounted to the support mounting structure 71. In the present embodiment, a wing screw is used as the ruler coupling bolt 73.

[0100] The ruler pressing member 72 has a mounting plate portion 721 and a pressing portion 722. The pressing portion 722 is connected to the mounting plate portion 721. The ruler pressing member 72 is formed by bending one raw material plate.

[0101] The mounting plate portion 721 is mounted to one of the receiving plate portions 711b of the mounting member 711. A threaded hole is provided in the mounting plate portion 721. A through hole is provided in each of the pair of receiving plate portions 711b as a through hole 711c. By screwing the gauge combination bolt 73 that passes through the through hole 711c of one of the receiving plate portions 711b into the threaded hole of the mounting plate portion 721, the mounting plate portion 721 is mounted to one of the receiving plate portions 711b. Thus, the gauge pressing member 72 is mounted to the support mounting structure 71 in a detachable manner.

[0102] The gauge pressing member 72 is mounted to the support mounting structure 71, and thereby presses the gauge member 5 to the support member 4 with the pressing portion 722. Thus, the gauge member 5 is mounted to the support member 4.

[0103] Next, the step of arranging the mounting template device 1 of the elevator on the top of the hoistway 102 will be described. The mounting template device 1 is arranged on the top of the hoistway 102 by being mounted to the plurality of hoisting beams 104. When the mounting template device 1 is mounted to the plurality of hoisting beams 104, first, each support member 4 whose length is adjusted in accordance with the interval of the plurality of hoisting beams 104 is prepared. The length of each support member 4 is adjusted by adjusting the number of the extension support blocks 43b that are connected to the base support block 43a. Then, each support member 4 is placed on each hoisting beam 104 so as to span the plurality of hoisting beams 104. Then, each support member 4 is mounted to each hoisting beam 104 by the support mounting member 6.

[0104] Then, each gauge member 5 whose length is adjusted in accordance with the size and the arrangement position of the object to be positioned is prepared. In the present embodiment, a landing sill gauge member 5a whose length is adjusted in accordance with the size and the arrangement position of the landing sill, and a car guide rail gauge member 5b whose length is adjusted in accordance with the size and the arrangement position of the pair of car guide rails are prepared. The length of each gauge member 5 is adjusted by adjusting the number of the extension gauge block 54b that is connected to the base gauge block 54a.

[0105] Then, each gauge member 5 is placed on each support member 4 so as to span the plurality of support members 4. Then, each gauge member 5 is mounted to each support member 4 by the gauge mounting member 7. At this time, the position of each gauge member 5 in the horizontal direction is adjusted in accordance with the position at which the positioning of each object, i.e., the positioning of the landing sill and the pair of car guide rails, is performed.

[0106] After that, the plumb lines 3 suspending the weights 2 are connected to the connectors 53 of the respective gauge members 5. Thus, a pair of the plumb lines 3 connected to the connectors 53 of the gauge members 5a for the landing sill are pulled and arranged in the vertical direction in the hoistway 102 as the plumb lines 3a for the landing sill. Also, a pair of the plumb lines 3 connected to the connectors 53 of the gauge members 5b for the car guide are pulled and arranged in the vertical direction in the hoistway 102 as the plumb lines 3b for the car guide. At this time, in the case where the distance between the pair of the plumb lines 3a for the landing sill needs to be adjusted, the position of the connector main body 532 with respect to the protruding member 531 is adjusted in the connector 53 of the gauge member 5a for the landing sill. Also, in the case where the distance between the pair of the plumb lines 3b for the car guide needs to be adjusted, the position of the connector main body 532 with respect to the protruding member 531 is adjusted in the connector 53 of the gauge member 5b for the car guide. In this way, the installation template device 1 is arranged at the top of the hoistway 102.

[0107] In the installation template device 1 of the elevator as such, the gauge member main body 51 of each of the gauge members 5 has a plurality of gauge blocks 54. The plurality of gauge blocks 54 are continuously connected to each other in the length direction of the gauge member 5 in a detachable manner. The length of the gauge member main body 51 can be adjusted by adjusting the number of the gauge blocks 54. In each of the gauge members 5, one connector 53 is attached to the gauge block 54 at one end portion of the gauge member main body 51, and the other connector 53 is attached to the gauge block 54 at the other end portion of the gauge member main body 51. Therefore, it is not necessary to slide the gauge blocks 54 over each other in order to adjust the length of the gauge member main body 51. Thus, it is possible to eliminate the overlapping portions of the gauge blocks 54 from each other in the gauge member main body 51. Therefore, it is possible to achieve the weight reduction of the gauge member main body 51, and it is possible to achieve the weight reduction of the gauge member 5. Thus, it is possible to make the operation of the gauge member 5 easy.

[0108] Also, since it is possible to adjust the length of the gauge member 5 by adjusting the number of the gauge blocks 54, it is possible to use the common installation template device 1 even in the case where the positioning of the object is performed when installing the elevator of another kind or another size, for example. Thus, in the case where the elevator is installed, it is not necessary to prepare a plurality of installation template devices different from each other in accordance with the kind and the size of the elevator. Therefore, it is possible to reduce the burden of the manufacturing management and the inventory management of the installation template device 1.

[0109] Further, the link member 52 of the ruler member 5 has a link member main body 521, a first fastening bolt 522, and a second fastening bolt 523. The link member main body 521 is arranged across the boundary of two ruler blocks 54 adjacent to each other. The first fastening bolt 522 fastens the link member main body 521 to one ruler block 54. The second fastening bolt 523 fastens the link member main body 521 to the other ruler block 54. Thus, the two ruler blocks 54 adjacent to each other can be more reliably linked. Further, the two ruler blocks 54 can be arranged imitating the link member main body 521 at the boundary of the two ruler blocks 54, and the ruler member 5 can be prevented from being bent at the boundary of the two ruler blocks 54. Thus, the state of the ruler member 5 along the straight line can be more reliably maintained.

[0110] Further, in each of the link members 53, the link plummet line 3 is attached to the link member main body 532 in a detachable manner. On the protruding member 531, a plurality of through holes as a plurality of adjustment holes 534 are provided at intervals from each other in the length direction of the ruler member 5. The link member main body 532 is attached to the protruding member 531 in a state of being selectively arranged in any of the plurality of adjustment holes 534. Thus, by changing the adjustment hole 534 through which the link member main body 532 passes, the position of the plummet line 3 connected to the ruler member 5 can be adjusted in the length direction of the ruler member 5. Thus, by making the interval of the plurality of adjustment holes 534 shorter than the size of the ruler block 54, the position of the plummet line 3 can be adjusted more finely and easily than the adjustment of the number of the ruler blocks 54.

[0111] Further, in the support mounting member 6, the support structure 62 holds the support pressing member 61 to the support member 4. The support structure 62 has a sliding member 621 attached to the support member 4 in a slidable manner, and a support fastening bolt 622 attached to the sliding member 621. The support fastening bolt 622 holds the holding portion 612 of the support pressing member 61 to the support member 4 by pressing the holding portion 612 against the support member 4. The support pressing member 61 presses a part of the crane beam 104 against the support member 4 through the hooking portion 611 in a state where the holding portion 612 is elastically deformed between the support fastening bolt 622 and the support member 4. Thus, a part of the crane beam 104 can be held between the hooking portion 611 and the support member 4 by the elastic restoring force of the holding portion 612 of the support pressing member 61. Thus, the support member 4 can be easily attached to the crane beam 104. Further, excessive force can be prevented from being applied to the crane beam 104 and the support member 4, and thus the crane beam 104 and the support member 4 can be prevented from being damaged. Moreover, a state where the holding portion 612 is applied with the elastic restoring force to the support fastening bolt 622 can be maintained, and thus the support fastening bolt 622 can be prevented from being loosened.

[0112] Further, a fitting structure portion 58 is provided at the boundary of two ruler blocks 54 adjacent to each other. The fitting structure portion 58 has a protrusion portion 581 protruding from one ruler block 54 and a recessed portion 582 formed in the other ruler block 54. The protrusion portion 581 is fitted into the recessed portion 582. Thus, it is possible to prevent one ruler block 54 from being shifted with respect to the other ruler block 54 along the boundary of the two ruler blocks 54. Thereby, it is possible to more reliably maintain the state in which the ruler member 5 is aligned along a straight line.

[0113] Further, the fitting structure portion 58 is provided at the boundary of the back plate portion 541 of each of the two ruler blocks 54 and the boundary of the side plate portion 542 of each of the two ruler blocks 54. Thus, it is possible to prevent each of the ruler blocks 54 from being shifted in a plurality of directions along the boundary of the two ruler blocks 54 by each of the fitting structure portions 58. Thereby, it is possible to more reliably maintain the state in which the ruler member 5 is aligned along a straight line.

[0114] Further, the ruler mounting member 7 has a support mounting structure 71, a ruler pressing member 72, and a ruler coupling bolt 73. The support mounting structure 71 is detachably mounted to the support member 4. The ruler pressing member 72 presses the ruler member main body 51 to the support member 4. The ruler coupling bolt 73 mounts the ruler pressing member 72 to the support mounting structure 71. Thus, it is possible to easily and more reliably mount the ruler member 5 to the support member 4.

[0115] Further, in the above-described embodiment, the number of the support members 4 is two and the number of the ruler members 5 is two. However, the number of the support members 4 can be three or more. Further, the number of the ruler members 5 can be three or more according to the number of the positioning target objects.

[0116] Further, in the above-described embodiment, a plurality of adjustment holes 534 are provided in the protrusion member 531 in either of the pair of the connecting members 53 of each of the ruler members 5, whereby it is possible to adjust the connection position of the plummet line 3 with respect to the ruler member 5. However, it is also possible to adjust the connection position of the plummet line 3 with respect to the ruler member 5 in only one of the pair of the connecting members 53. Further, it is also possible to fix the connection position of the plummet line 3 with respect to the ruler member 5 so as not to be adjustable in either of the pair of the connecting members 53.

[0117] Further, in the above-described embodiment, the two ruler blocks 54 adjacent to each other are connected by the link member 52. However, if the two ruler blocks 54 can be connected to each other even without the link member 52, it is also possible to have no link member 52. For example, a part of each of the ruler blocks 54 can be provided as a permanent magnet, and the two ruler blocks 54 can be connected to each other by the magnetic force of the permanent magnets.

[0118] Further, in the above embodiment, the fitting structure portions 58 are provided at the boundaries of two ruler blocks 54 adjacent to each other. However, the fitting structure portions 58 can be omitted. Even if the fitting structure portions 58 are omitted, the plurality of ruler blocks 54 can be continuously and detachably connected to each other in the ruler member 5, and the length of the ruler member body 51 can be adjusted by adjusting the number of the ruler blocks 54.

[0119] Further, in the above embodiment, the plurality of support blocks 43 are continuously connected in the support member 4. However, the structure of the support member 4 is not limited thereto. For example, a rod without a joint through which the length adjustment is not possible can be used as the support member 4.

[0120] Further, in the above embodiment, the length of the base ruler block 54a is longer than the length of the extension ruler block 54b. However, the length of the base ruler block 54a can be set to the same length as the length of the extension ruler block 54b, and the lengths of the plurality of ruler blocks 54 in each ruler member 5 can be all set to the same length. In this way, the lengths of the ruler blocks 54 can be unified, and the ruler blocks 54 can be easily manufactured.

[0121] In the above embodiment, in the ruler member 5, the lengths of the plurality of extension ruler blocks 54b are all the same length. However, the lengths of the plurality of extension ruler blocks 54b in the ruler member 5 can be set to different lengths from each other. In this way, by adjusting the combination of the lengths of the plurality of extension ruler blocks 54b, the adjustment of the length of the ruler member body 51 can be performed more finely.

[0122] The above-described structure of the above embodiment represents one example of the content of the present disclosure. The embodiment can be combined with other known technologies. A part of the structure of the embodiment can be omitted or changed within a range not departing from the gist of the present disclosure.

[0123] Hereinafter, examples of the modes that can be included in the present disclosure are explicitly described as appendices.
