The jack bolt 54 is screwed into the screw holes 52b and 52c of the first attachment metal 52A, and the tip of the jack bolt 54 protruding from the screw holes 52b and 52c is directed to the low floor portion 7a, and the anchor bolt 51 is inserted into the long hole 52a. The top end of the jack bolt 54 is brought into contact with the upper surface of the low floor portion 7a. Further, the longitudinal direction of the first attachment metal (the longitudinal direction of the long hole 52a) is set to the depth direction so that the other end side in the longitudinal direction of the first attachment metal 52A extends from the low floor portion 7a to the hoistway 2 side. Match. The depth direction is a direction that is perpendicular and horizontal to the opening direction of the hall opening 3a.

Next, the pressing nut 60 is tightened so as to press the first attachment metal 52A. Thus, one first attachment metal 52A is supported on the low floor portion 7a.
Similarly, the other first attachment metal 52A is supported on the low floor portion 7a so as to be symmetrical with the first attachment metal 52A with respect to the center of the hall opening 3a.

Next, the head of the sill mounting bolt 58a is fitted to one end of the sill fixing hole 5b, and the sill mounting bolt 58a is slid along the sill fixing hole 5b and attached to the sill 5A. Further, the shaft portion of the sill mounting bolt 58a is inserted into the through hole 53b of the second mounting metal 53A, and the sill mounting nut 59 is screwed into the shaft portion.
Thus, one second attachment metal 53A is attached to the sill 5A. At this time, the sill attachment nut 59 is not tightened, and the second attachment metal 53A is slidable along the sill fixing hole 5b.
Similarly, the other second attachment metal 53A is attached to the sill 5A.

Next, the direction of the second mounting metal 53A is adjusted so that one end side of each of the pair of second mounting metal 53A extends from the sill 5A to one side in the groove width direction of the sill groove 5a of the sill 5A, 2. Slide the attachment metal 53A to a position corresponding to the first attachment metal 52A. Furthermore, one end side of the second attachment metal 53A is disposed above the other end side of the first attachment metal 52A. Next, the connecting bolt 55 is inserted into the elongated hole 53a of the second mounting metal 53A and screwed into one of the screw holes 52d of the first mounting metal 52A. Thereby, one second attachment metal 52A is fastened and fixed to the first attachment metal 52A.

Similarly, the other second attachment metal 53A is fastened and fixed to the first attachment metal 52A.

  Next, each of the pair of sill mounting nuts 59 is tightened, and the lower part of the sill 5A and the second mounting metal 53A are sandwiched between the heads of the pair of sill mounting bolts 58a and the pair of sill mounting nuts 59, and the second mounting. The space between the gold 53A and the threshold 5A is fixed.

  Next, if necessary, the pressing nut 60 is loosened, and the first mounting brackets of the four jack bolts 54 are arranged so that the height position of the upper surface of the sill 5A coincides with the floor finish surface indicated by the two-dot chain line in FIG. After adjusting the protruding amount from 52A, the pressing nut 60 is tightened to fix the first attachment metal 52A. And it confirms that the upper surface of the present sill 5A is horizontally arrange | positioned at the same height position as a floor finishing surface, and the height position of the upper surface of the sill 5A has shifted | deviated from the height position of the floor finishing surface. In this case, the amount of protrusion of the jack bolt 54 from the first attachment metal 52A is adjusted again.

Here, in order to arrange the floor finish surface and the upper surface of the sill 5A at the same height position, it is necessary to arrange the pair of first attachment metal 52A while maintaining the level at a predetermined height. It is difficult to adjust the amount of protrusion of the four jack bolts 54 from the first attachment metal 52A at a time to align the pair of first attachment metal 52A at a predetermined height while maintaining the level. For this reason, while adjusting the protruding amount of the four jack bolts 54 from the first attachment metal 52A little by little, the first attachment metal 52A is set to a predetermined height so that the upper surface of the sill 5A is the same height as the floor finish surface. It will be moved to the position. Therefore, it takes a long time to support the threshold 5A at a desired installation position.

Next, the pair of sill mounting nuts 59 is slightly loosened, and the sill 5A is slid in the opening direction of the landing opening 3a to place the sill 5A at a desired position in the front opening direction, and the pair of sill mounting nuts 59 is tightened. Thus, the space between the threshold 5A and the second attachment metal 53A is strongly fixed.
As described above, the threshold 5A is supported at a desired installation position.

Next, an operation of fixing the sill 5A to the building wall 9 extending in the vertical direction using the sill book fixing tool 61 will be described.
First, the head of the sill book fixing bolt is fitted to one end of the sill fixing hole 5b and slid and moved, and the sill book fixing bolt is attached to the sill 5A.

  Next, a pair of main anchor bolts are separated by a distance in the height direction at a predetermined portion of the building wall 9 on one side of one sill support jig 50A with respect to the frontage direction of the landing opening 3a, and below the sill 5A, And, it is driven by making the axial direction coincide with the depth direction. At this time, when one piece of the support portion 63 is pressed against the lower surface of the sill 5A and the other piece is extended downward, the height position of the longitudinal center of the long hole 63b on the other side is approximately that of the fixed anchor bolt. Drive this fixed anchor bolt so that it is at the height of the shaft center.

  Next, with one piece of the support portion 63 facing upward, the pair of long holes 63b of the other piece is fitted into the pair of main anchor bolts, and the main nut is screwed into one end of the main anchor bolt. Next, after the sill main fixing bolt is slid and moved above the main fixing anchor bolt, the one through hole 63a of the support portion 63 is inserted into the shaft portion of the sill main fixing bolt extending from the sill fixing hole 5b. .

The fixing means 22 includes a sill mounting bolt 23 and a sill mounting nut 24.

Further, as shown in FIG. 4, the other sill support jig 10B is configured in the same manner as the sill support jig 10A except that the first attachment metal 12B is used instead of the first attachment metal 12A.
As shown in FIG. 8, when the first connecting piece 12B is viewed from the surface where the adjustment bolt insertion piece 13 is not extended, the first connecting piece 14B has an elongated hole 14b which is a notch recessed hole 14a. It is formed and configured so as to be arranged on the other side of the cutout concave hole 14a with respect to the width direction. The configuration of the other first attachment metal 12B is the same as that of the first attachment metal 12A.

  In FIG. 9, the sill book fixing tool 30 includes a first sill fixing metal 31 formed in a U shape having a bottom part 31 </ b> A and opposing side pieces 31 </ b> B and 31 </ b> C, and fixed metal connection pieces 32 </ b> A and orthogonal to each other.

Each of the side pieces 31B and 31C is formed with a pair of through holes 31b that are separated from each other in the longitudinal direction of the first sill fixing metal 31.

  Further, a pair of through holes 32a are formed in the fixed metal connecting piece 32A of the second sill fixed metal 32 so as to be spaced apart in a direction perpendicular to the sill support piece 32B, and the sill support piece 32B has a predetermined width. The long hole 32b is formed so that the longitudinal direction coincides with the direction perpendicular to the fixed metal connecting piece 32A.

  The distance between the pair of through holes 31b in the side pieces 31B and 31C is equal to the distance between the pair of through holes 32a in the fixed metal connecting piece 32A. Then, when the first sill fixing metal 31 and the second sill fixing metal 32 are arranged so that the pair of through holes 32a correspond to the pair of through holes 31b and the fixed metal coupling piece 32A is along the side pieces 31B and 31C, The sill support piece 32 </ b> B side of the second sill fixing metal 32 extends from one end of the first sill fixing metal 31 in the longitudinal direction.

Next, an operation of supporting the threshold 5A at a desired installation position using the threshold support jigs 10A and 10B will be described.
3 to 5, first, the anchor bolt 11 is driven into a predetermined portion of the low floor portion 7a located on one side of the center of the hall opening 3a in the frontage direction.
Next, the four jack bolts 19 are screwed into the screw holes 13b of the adjustment bolt insertion pieces 13 of the first mounting bracket 12A from the first connecting piece 14A side, and the tip ends of the jack bolts 19 slightly from the adjustment bolt insertion pieces 13. To protrude.
Next, the elongated bolt 13a of the adjustment bolt insertion piece 13 is fitted to the anchor bolt 11, the adjustment bolt insertion piece 13 is positioned on the low floor portion 7a, and the first connection piece 14A is directed to the hoistway 2 side, In addition, the first attachment metal 12 </ b> A is disposed so as to extend above the adjustment bolt insertion piece 13.
Thereby, the front-end | tip of the jack volt | bolt 19 is contact | abutted on the upper surface of the low floor part 7a. Next, the pressing nut 20 is screwed onto the distal end side of the anchor bolt 11.

  Next, the protruding amount of the jack bolt 19 from each adjustment bolt insertion piece 13 is finely adjusted so that the first connecting piece 14 </ b> A extends upward in the vertical direction from the adjustment bolt insertion piece 13. This operation is performed while placing a leveler (not shown) on the adjustment bolt insertion piece 13 and checking the level of the adjustment bolt insertion piece 13 so that the adjustment bolt insertion piece 13 extends horizontally.

When installing hall equipment such as the sill 5A, a pair of piano wires (not shown) for centering the hall equipment is hung down vertically so as to pass near the hall opening 3a, and a pair of pianos The direction in which the lines are separated from each other is used as a reference for the frontage direction of the hall opening 3a.
Using this piano wire, the orientation of the connecting piece 14A is adjusted so that the connecting piece 14A is parallel to the separating direction of the pair of piano wires, that is, parallel to the frontage direction of the hall opening 3a.
In this manner, one first attachment metal 12A is supported on the low floor portion 7a.

  Similarly, the other first attachment metal 12B is supported on the low floor portion 7a so as to be symmetric with respect to the first attachment metal 12A with respect to the center of the hall opening 3a. Thereby, the direction of the notch recessed hole 14a and the long hole 14b of 1st connection piece 14A, 14B corresponds to a perpendicular direction. Further, the pressing nut 20 is tightened to temporarily fix the first mounting brackets 12A and 12B. In addition, temporary fixation means what can move 1st attachment metal 12A, 12B when force more than predetermined is applied along the long hole 13a with respect to 1st attachment metal 12A, 12b. Further, the height positions of the pair of first mounting brackets 12A and 12B do not have to coincide with each other.

  Next, as shown in FIGS. 10 and 11, the heads of the bolts 23 and 37 are fixed to the sill in the order of the sill book fixing bolt 37, the pair of sill mounting bolts 23, and the other sill book fixing bolt 37. It is fitted to one end of the hole 5b, and the sill mounting bolt 23 and the sill main fixing bolt 37 are sequentially slid and attached to the sill 5A.

Next, the tip of the sill support piece 32B of the second sill fixing metal 32 is directed to the side opposite to the side piece 31B of the first sill fixing metal 31, and the side of the first sill fixing metal is inserted into the through hole 32a of the fixed metal connection piece 32A. Align with the through hole 31b of the piece 31B. Next, the fixed metal connecting bolt 39 is inserted into the through holes 32a and 31b, the fixed metal connecting nut 40 is screwed into the fixed metal connecting bolt 39, and the fixed metal connecting piece 32A is fastened and fixed to the side piece 31B.
In the same manner, another fixed metal connecting piece 32A of the second sill fixing metal 32 is fastened and fixed to the side piece 31C of the first sill fixing metal 31.

  Next, the shaft portions of the one and the other sill book fixing bolts 37 are inserted into the elongated holes 32b of the one and the other sill support pieces 32B.

Further, the main fixing nut 38 is screwed into each of the sill main fixing bolts 37, and the second sill fixing metal 32 is attached to the sill 5A. At this time, the main fixing nut 38 is not finally tightened, and allows the integrated first and second sill fixing metal 31 and 32 to be slidable along the sill fixing hole 5b and the long hole 32b.
In this way, the second sill fixing metal 32 fixed to the first sill fixing metal 31 of the one sill book fixing tool 30 is attached to the sill 5A.
Although not shown in detail, similarly, the second sill fixing metal 32 is fixed to the first sill fixing metal 31 of the other (other) sill book fixing tool 30, and the first and second sill fixing metal 31 are fixed. , 32 are attached to the sill 5A so as to be located on the other end side in the longitudinal direction of the sill 5A with respect to the first and second sill fixing metal 31, 32 of one sill book fixing tool 30.

  Next, as shown in FIGS. 3 and 4, the second connecting piece 17 is opposed to one side surface in the groove width direction of the sill groove 5a of the sill 5A, and the sill support piece 16 is opposed to the lower surface of the sill 5A. As described above, the second attachment metal 15 is disposed, and the notch 16a of the sill support piece 16 is fitted to the sill attachment bolt 23 disposed between the pair of sill support pieces 32B of the one sill book fixing tool 30. Next, the sill mounting nut 24 is screwed onto the sill mounting bolt 23.

  As described above, one second attachment metal 15 is attached to the sill 5A. At this time, the sill mounting nut 24 is not tightened, and the second mounting metal 15 is slidable along the sill fixing hole 5b.

  Then, in the same manner as the one of the second mounting brackets 15, the other second mounting bracket 15 is slidable corresponding to the sill mounting bolts 23 disposed between the pair of sill support pieces 32 </ b> B of the other sill main fixing tool 30. Attach to 5A. At this time, the other second attachment metal 15 is attached to the sill 5A so that the pair of cutout concave holes 14a of the one and the other second attachment metal 15 are disposed inside the pair of long holes 14b.

  Next, the square root bolts 26 are inserted into the two bolt insertion holes 17a of the pair of second connection pieces 17 located on the inner side in the longitudinal direction of the sill 5A from the sill support piece 16 side, The connecting piece fastening nut 27 is screwed onto the tip side of the square root bolt 26.

  Further, the pair of second mounting brackets 15 are arranged in the first and second positions so that the pair of square root bolts 26 are arranged at positions corresponding to the cutout concave holes 14a of the pair of first connecting pieces 14A, 14B. It is slid along the sill fixing holes 31 and 32 along the sill fixing holes 5b.

Furthermore, the sill support piece 16 is directed to the opposite side of the first connection pieces 14A and 14B, the second connection piece 17 is opposed to the first connection pieces 14A and 14B, and the shaft portions of the pair of square root bolts 26 are The pair of cutout concave holes 14a are inserted from above. In other words, the second fitting 15 is arranged so that the second connecting piece 17 is opposed to each of the first connecting pieces 14A and 14B with the bolt insertion hole 17a corresponding to the notch 14a and the long hole 14b. The square root bolt 26 is inserted into the cutout concave hole 14a and the bolt insertion hole 17a. Thereby, the 2nd connection piece 17 is attached to the 1st connection pieces 14A and 14B so that a movement to the length direction of the notch concave hole 14a and the long hole 14b is possible.
Next, the connecting piece fastening nut 27 is tightened to temporarily fix between the pair of second mounting brackets 15 and the pair of first mounting brackets 12A and 12B. At this time, the bolt insertion hole 17a into which the square root bolt 26 is not inserted is opposed to the elongated hole 14b.

  Temporary fixing here means that the second attachment metal 15 does not move relative to the first attachment metal 12A, 12B due to the gravity of the second attachment metal 15 and the threshold 5A. When a predetermined force or more is applied to 5A in the longitudinal direction of the cutout concave hole 14a, the second attachment metal 15 and the sill 5A are moved in the direction along the cutout concave hole 14a, in other words, in the height direction. This is what you can do.

  In addition, since play exists between the notch recessed hole 14a of a pair of 1st attachment metal 12A, 12B and the square root bolt 26, the height position of a pair of square root bolt 26 shifts | deviates, and the length of the threshold 5A The direction is slightly inclined with respect to the horizontal plane. Therefore, a leveler (not shown) is placed on the upper surface of the sill 5A, and one or the other second attachment metal 15 is shifted along the notch 14a in a direction to cancel the inclination of the sill 5A. Level the top surface of 5A.

  Further, until the shaft portion of the sill mounting bolt 23 comes into contact with the bottom of the notch 16a, the sill 5A is pushed toward the second connecting piece 17 to tighten the sill mounting nut 24, and the sill 5A is attached to the sill support piece 16. Fix it.

  Here, the driving position in the depth direction of the anchor bolt 11 is driven into a portion of the low floor portion 7a that is approximately a predetermined distance away from the threshold 5A with respect to the installation position in the depth direction of the desired threshold 5A. And when the 2nd attachment metal 15 is connected with respect to 1st attachment metal 12A, 12B which fitted and fixed the anchor bolt 11 to the intermediate part of the longitudinal direction of the long hole 13a, the threshold 5A of the installation position which 5A desires is desirable. It is arranged around. Here, since the hole direction of the long hole 13a coincides with the depth direction, the first attachment metal 12A can be shifted in the depth direction within the range of the long hole 13a.

Since there is play between the long hole 13a and the anchor bolt 11, for example, a force is applied alternately to the pair of first mounting brackets 12A and 12B in the depth direction, and the depth direction of the first mounting brackets 12A and 12B. If the position is moved little by little, the installation position in the depth direction of the sill 5A can be adjusted. Further, the threshold 5A around the anchor bolt 11 can be finely adjusted. Then, the positions of the first mounting brackets 12A and 12B in the depth direction and the positions around the anchor bolts 11 are arranged so that the sill 5A is arranged in parallel with the opening direction of the hall opening 3a at the desired installation position in the depth direction. adjust.
In addition, when the upper surface of the sill 5A is inclined from the horizontal due to the movement of the first mounting metal 12A, 12B, the amount of protrusion of the jack bolt 19 from the first mounting metal 12A, 12B is finely adjusted again to adjust the upper surface of the sill 5A. Make it horizontal.

  Next, the pressing nut 20 is tightened, and the first mounting metal 12 </ b> A and 12 </ b> B are fixed by the pressing nut 20 and the jack bolt 19. Further, the sill attachment nut 24 is loosened, the position in the frontage direction of the sill 5A is adjusted to a desired position, and the sill attachment nut 24 is tightened again to fix the second attachment metal 15 and the sill 5A.

  Next, the position of the second attachment metal 15 is adjusted so that the upper surface of the sill 5A is horizontally disposed at the same height position as the floor finish surface. As described above, there is play between the cutout recess 14a of the pair of first mounting brackets 12A and 12B and the square root bolt 26. Therefore, for example, a force is alternately applied to the pair of first mounting brackets 12A and 12B in the height direction, and the height positions of the pair of first mounting brackets 12A and 12B are alternately moved little by little. Adjust the top surface to the same height as the floor finish. Next, the connecting piece fastening nut 27 is tightened to firmly fix the first connecting pieces 14 </ b> A and 14 </ b> B and the second connecting piece 17.

Further, the square root bolt 26 is inserted from the bolt insertion hole 17a side into the elongated hole 14b and the bolt insertion hole 17a opposite to the elongated hole 14b, and the connecting piece fastening nut 27 is tightened to the square root bolt 26. The space between the first connecting pieces 14A, 14B and the second connecting piece 17 is further fixed.
As described above, the threshold 5A is supported at a desired installation position.

  Further, the first and second sill fixing metal 31 and 32 of the pair of sill book fixing tools 30 are slid in the longitudinal direction of the long hole 32b until the bottom 31A of the first sill fixing metal 31 is pressed against the building wall 9. Let Next, holes for driving the fixed anchor bolts 34 are made in the building wall 9 through the long holes 31a of the bottom 31A. And this fixed anchor bolt 34 is inserted in the long hole 31a formed in the bottom part 31A of each 1st sill fixed metal 31 so that an axial direction may correspond to a depth direction, and it fixes to the hole formed in the building wall 9. .

  Next, an anchor screw nut 35 is screwed into each main fixing anchor bolt 34, and the bottom 31 </ b> A is fastened and fixed to the building wall 9. Further, the fixing nut 38 is tightened to fix the threshold 5A to the threshold support piece 32B. Thereby, the sill 5 </ b> A is fixed to the building wall 9 via the pair of sill book fixing tools 30.

Next, the anchor bolt 11, the first attachment metal 12A, 12B, and the second attachment metal 15 are removed. The sill mounting nut 24 once removed to remove the second mounting metal 15 is fastened to the sill mounting bolt 23 again after the second mounting metal 15 is removed.
Thus, the installation work of the sill 5A is completed.
Next, the floor of the hall 3 is configured by covering the building floor 7A with a mortar and a floor finishing material (not shown).

Next, a case where the pair of sill support jigs 10A and 10B is provided on the building floor of the hall with a small distance from the floor finish surface to install the sill 5A will be described.
FIG. 12 is a cross-sectional view for explaining another installation example of the sill using the sill support jig according to the embodiment of the present invention.
In FIG. 12, the same or corresponding parts as those in FIGS. 1 to 11 and 16 are denoted by the same reference numerals, and the description thereof is omitted. Moreover, in FIG. 12, illustration of a sill book fixing tool is omitted for convenience of explanation.
In FIG. 12, the method of installing the sill 5A using the pair of sill support jigs 10A, 10B installed on the building floor 7B is the method of installing the sill 5A using the pair of sill support jigs 10A, 10B installed on the building floor 7A. It is the same as the method of installing.

  When adjusting the height position of the upper surface of the sill 5A, the height position of the upper surface of the sill 5A depends on the bolt insertion hole 17a and the shaft portion of the square root bolt 26 inserted into the cutout concave hole 14a or the long hole 14b. When it is arranged at the lower end of the cutout concave hole 14a and the long hole 14b, it becomes the lowest.

  The height obtained by adding the thickness in the vertical direction of the sill 5A to the height position of the upper surface of the sill support piece 16 when the shaft portion of the square head bolt 26 is disposed at the lower ends of the cutout concave hole 14a and the long hole 14b. If the distance between the bolt insertion hole 17a and the sill support piece 16 is set so that the height is not higher than the floor finish surface, the sill 5A is supported on the upper part of the sill support piece 16 and is desired. It can be arranged at the installation position.

  The sill support jigs 10A and 10B according to this embodiment include anchor bolts 11 that are driven in the vertical direction to the building floors 7A and 7B, the adjustment bolt insertion pieces 13, and the first connection pieces 14A and 14B. The long hole 13a is formed in the adjusting bolt insertion piece 13 so that the longitudinal direction of the hole coincides with the direction perpendicular to the first connecting pieces 14A and 14B. A hole 14b is formed in the first connecting pieces 14A and 14B with the longitudinal direction of the hole aligned with the direction perpendicular to the adjusting bolt insertion piece 13, and the long hole 13a is formed in the anchor bolt 11 driven into the building floor 7A and 7B. The adjustment bolt insertion piece 13 is placed on the building floor 7A, 7B, and the first connection pieces 14A, 14B are arranged to extend above the adjustment bolt insertion piece 13 toward the hoistway 2 side. 1 Mounting bracket 1 A and 12B are respectively screwed into the adjustment bolt insertion piece 13 so that the amount of protrusion from the adjustment bolt insertion piece 13 can be adjusted, and the inclination of the adjustment bolt insertion piece 13 disposed on the building floors 7A and 7B is adjusted. A plurality of jack bolts 19 and a screw nut 20 which is screwed to the anchor bolt 11 and cooperates with the jack bolt 19 to fix the adjusting bolt insertion piece 13 to the building floor 7A, 7B, the sill support piece 16 and the bolt insertion. The second connecting piece 17 is formed in an L shape having a second connecting piece 17 in which a hole 17a is formed. The second connecting piece 17 has a bolt insertion hole 17a cut away to correspond to the recessed hole 14a and the elongated hole 14b, and the first connecting piece 14A, 1st connection so that the sill support piece 16 may be opposed to the first connection pieces 14A and 14B and may be moved in the length direction of the cutout concave holes 14a and the long holes 14b so as to face the 14B. Piece 1 A second mounting bracket 15 attached to A and 14B and supporting the sill 5A to the sill support piece 16, a square root bolt 26 inserted through the bolt insertion hole 17a and the cutout concave hole 14a (long hole 14b), and A connecting piece fastening nut 27 that is screwed into the square root bolt 26 and fastens and fixes the second connecting piece 17 to the first connecting piece 14A, and a fixing means 22 that fixes the sill 5A to the sill support piece 16. I have.

  According to the sill support jigs 10A and 10B, the cutout concave holes 14a and the long holes 14b are formed on the first connecting pieces 14A and 14B that are directed to the hoistway 2 side and extend above the adjustment bolt insertion pieces 13. The second attachment metal 15 is attached so as to be movable in the longitudinal direction, in other words, in the height direction. Thereby, the jack bolts 10A and 10B are used for leveling the upper surface of the sill 5A, in other words, for adjusting the inclination of the adjusting bolt insertion piece 13, and the adjustment of the height position of the sill 5A is performed by the jack bolts 10A and 10B. The second attachment metal 15 can be carried out by simply moving in the longitudinal direction of the cutout concave holes 14a and the long holes 14b of the first connecting pieces 14A and 14B.

Further, by shifting the first attachment metal 12A, 12B in the longitudinal direction of the long hole 13a, the position in the depth direction of the sill 5A can be easily adjusted, and the notched concave hole 14a and the long hole 14b of the square root bolt 26 are provided. The insertion position can be set to a desired position in the longitudinal direction of the cutout concave hole 14a and the long hole 14b, and the height position of the sill 5A can be easily adjusted.
Therefore, compared to the conventional case where adjustment of both the height position and leveling of the sill is performed by the jack bolt, the work efficiency when the sill 5A is supported at a desired installation position by using the sill support jigs 10A and 10B. Is significantly improved, and the threshold can be supported at a desired installation position in a short time.

  Here, in the case where the sill 5B is supported at a desired installation position using the conventional second sill support jig 50B installed on the building floor 7B of the hall 3 with a small distance from the floor finish surface, the above-described case is used. Thus, the sill attachment hole 5c must be formed on the design surface of the sill 5B, and there is a problem that the design of the sill 5B is impaired.

On the other hand, when supporting the sill 5A at a desired installation position using the sill support jigs 10A and 10B installed on the building floor 7B, the sill 5A is placed on the upper part of the sill support piece 16 as described above. The height position of the upper surface of the sill 5A can be matched with the height position of the floor finish surface. Thereby, it becomes unnecessary to form a hole or the like for fixing the sill 5A to the second attachment metal 15 on the design surface of the sill 5B, and it is possible to avoid the design property of the sill 5A from being impaired.
Conventionally, the first and second conventional sill support jigs 50A and 50B having different configurations are used to support the sills 5A and 5B with respect to the low floor portion 7a and the building floor 7B of the building floor 7A. It was necessary to prepare. On the other hand, the sill support jigs 10A and 10B can support the sill 5A at a desired installation position even if the sill support jigs 10A and 10B are commonly used for the low floor portion 7a and the building floor 7B of the building floor 7A.

  Moreover, according to the installation method of the elevator sill using the sill support jigs 10A and 10B, the jack bolt 19 is used in the step of adjusting the inclination of the adjustment bolt insertion piece 13, and the height of the sill 5A and 5B is adjusted. The adjustment is performed only by moving the second attachment metal 15 in the direction of the cutout concave hole 14a and the long hole 14b of the first connecting pieces 14A and 14B without using the jack bolt 19. Therefore, the working efficiency when supporting the sill 5A at a predetermined position using the sill support jigs 10A and 10B can be remarkably improved, and the sill can be supported at a desired installation position in a short time.

In the above-described embodiment, the first connecting pieces 14A and 14B of the first attachment metal 12A and 12B have been described as having the cutout concave holes 14a and the elongated holes 14b. One of 14a and the long hole 14b may be omitted.
Moreover, after attaching the sill support piece 16 to the sill 5A, 5B, it demonstrated as the sill 5A being supported by the sill support piece 16 by fixing the 2nd attachment money 15 to the 1st attachment metal 12A, 12B. The sill support pieces 16 may support the sills 5A and 5B after the second mounting metal 15 is attached to the first mounting metal 12A and 12B.

  Further, the cutout concave hole 14a of the first connecting pieces 14A and 14B may be a long hole, and the long hole 14b may be a cutout concave hole. However, by forming the cutout concave hole, the shaft portion of the square head bolt 26 that has been previously inserted through the bolt insertion hole 17a can be inserted into the cutout concave hole 14a. The second mounting metal 15 that supports the first mounting metal 12A and 12B can be easily attached. Further, in advance, the square root bolt 26 is inserted into the second connecting piece 17 and the connecting piece fastening nut 27 is screwed into the square root bolt 26. Since it can be set as the state penetrated to the hole 14a, the risk of dropping the connection piece fastening nut 27 etc. to the hoistway 2 can be reduced.

  Further, in the step of matching the height of the upper surface of the sill 5A with the height of the floor finish surface, a force is applied alternately to the pair of first mounting brackets 12A and 12B in the height direction, and the pair of first mounting brackets. Although the height positions of 12A and 12B are alternately moved little by little, the upper surface of the sill 5A has been described as being the same height as the floor finish surface. For example, a plurality of workers support the part of the sill 5A that is spaced apart in the longitudinal direction, loosen the connecting piece fastening nut 27, and after matching the height of the upper surface of the sill 5A with the height of the floor finish surface, The connecting piece fastening nut 27 may be fixed.

  Further, the first mounting brackets 12A and 12B are composed of adjustment bolt insertion pieces 13 and first connection pieces 14A and 14B which are orthogonal to each other, and the longitudinal direction of the long hole 13a is perpendicular to the first connection pieces 14A and 14B. It has been described that the longitudinal direction of the cutout concave hole 14 a and the long hole 14 b coincides with the direction perpendicular to the adjustment bolt insertion piece 13. However, as long as the first attachment metal is formed in an L shape, the adjustment bolt insertion piece and the first connection piece may not be orthogonal to each other, and the longitudinal direction of the elongated hole is the same as that of the adjustment bolt insertion piece. It coincides with the direction from the tip toward the first connecting piece, and the longitudinal direction of the cutout concave hole 14a and the long hole 14b coincides with the direction from the tip of the first connecting piece 14A, 14B toward the adjusting bolt insertion piece 13. That's fine.

  Moreover, although the 2nd attachment metal 15 demonstrated as what consists of the sill support piece 16 and the 2nd connection piece 17 which are mutually orthogonally crossed, if the 2nd attachment metal is formed in L shape, a sill support piece and The 2nd connection piece does not need to be orthogonal.
