The second plate fixing portion 52c protrudes toward the first frame side plate 51 at right angles from the second connecting portion 52b. The intermediate plate 53 is fixed to the second plate fixing portion 52c.
　図５は、図２の空間形成体２２の組立途中の状態を示す斜視図である。空間形成体２２を組み立てる場合、まず下枠３４上に底板４１がセットされる。このとき、第１凸部４１ａが第１吊枠３１内に挿入され、第２凸部４１ｂが第２吊枠３２内に挿入される。 FIG. 5 is a perspective view showing a state in which the space forming body 22 of FIG. 2 is being assembled. When assembling the space forming body 22 , the bottom plate 41 is first set on the lower frame 34 . At this time, the first protrusion 41 a is inserted into the first suspension frame 31 and the second protrusion 41 b is inserted into the second suspension frame 32 .
　この後、図５に示すように、後カバー４３の最下段の分割体５０、及び前カバー４２の最下段の分割体５０が、底板４１上に組み立てられる。各分割体５０の組立においては、第１枠側板５１が第１吊枠３１に固定され、第２枠側板５２が第２吊枠３２に固定される。そして、第１枠側板５１と第２枠側板５２との間に、中間板５３が固定される。また、予め組み立てられた分割体５０を第１吊枠３１と第２吊枠３２とに固定してもよい。 After that, as shown in FIG. 5 , the lowermost divided body 50 of the rear cover 43 and the lowermost divided body 50 of the front cover 42 are assembled on the bottom plate 41 . In assembling each divided body 50 , the first frame side plate 51 is fixed to the first suspension frame 31 and the second frame side plate 52 is fixed to the second suspension frame 32 . An intermediate plate 53 is fixed between the first frame side plate 51 and the second frame side plate 52 . Also, the divided body 50 assembled in advance may be fixed to the first suspension frame 31 and the second suspension frame 32 .
　この後、前カバー４２及び後カバー４３のそれぞれについて、必要な段数だけ、複数の分割体５０が第１吊枠３１と第２吊枠３２との間に固定される。 After that, for each of the front cover 42 and the rear cover 43, a plurality of divided bodies 50 are fixed between the first suspension frame 31 and the second suspension frame 32 by the required number of steps.
　空間形成体２２が組み立てられた後、収容空間２６内に質量体２３が流し込まれる。そして、質量体２３が硬化した後、質量体２３上に上カバー２４が載せられ、一対の押さえ具２５が釣合おもり枠２１に取り付けられる。 After the space forming body 22 is assembled, the mass body 23 is poured into the accommodation space 26 . After the mass body 23 is cured, the upper cover 24 is placed on the mass body 23 and a pair of pressers 25 are attached to the counterweight frame 21 .
　このような釣合おもり装置９では、空間形成体２２は、底板４１、前カバー４２、及び後カバー４３を有している。前カバー４２及び後カバー４３のそれぞれは、複数の分割体５０を有している。各分割体５０は、第１枠側板５１、第２枠側板５２、及び中間板５３を有している。このため、質量体２３が収容される収容空間２６のサイズを容易に変更することができる。 In such a counterweight device 9 , the space forming body 22 has a bottom plate 41 , a front cover 42 and a rear cover 43 . Each of the front cover 42 and the rear cover 43 has a plurality of split bodies 50 . Each split body 50 has a first frame side plate 51 , a second frame side plate 52 and an intermediate plate 53 . Therefore, it is possible to easily change the size of the accommodation space 26 in which the mass body 23 is accommodated.
　例えば、図６は、釣合おもり枠２１の前後方向における質量体２３の寸法が図２よりも大きい釣合おもり装置を示す斜視図である。この場合、図３と同様の複数の中間板５３を用いつつ、底板４１、上カバー２４、各第１枠側板５１、及び各第２枠側板５２を変更することにより、収容空間２６のサイズを容易に変更することができる。 For example, FIG. 6 is a perspective view showing a counterweight device in which the dimension of the mass body 23 in the longitudinal direction of the counterweight frame 21 is larger than that in FIG. In this case, while using a plurality of intermediate plates 53 similar to those in FIG. can be easily changed.
　また、図７は、第１吊枠３１と第２吊枠３２との間隔が図２よりも大きい釣合おもり装置を示す斜視図である。この場合、図２と同様の複数の第１枠側板５１及び複数の第２枠側板５２を用いつつ、底板４１、上カバー２４、及び各中間板５３を変更することにより、収容空間２６のサイズを容易に変更することができる。 Also, FIG. 7 is a perspective view showing a counterweight device in which the distance between the first suspension frame 31 and the second suspension frame 32 is larger than that in FIG. In this case, while using a plurality of first frame side plates 51 and a plurality of second frame side plates 52 similar to those in FIG. can be easily changed.
　また、第１吊枠３１と第２吊枠３２との間隔の相違が小さければ、第１枠側板５１及び第２枠側板５２と中間板５３との重なり代を変更するだけで、収容空間２６のサイズを容易に変更することができる。 Further, if the difference in the distance between the first suspension frame 31 and the second suspension frame 32 is small, the accommodation space 26 can be adjusted by simply changing the overlapping margin between the first frame side plate 51 and the second frame side plate 52 and the intermediate plate 53 . can be easily resized.
　また、前カバー４２及び後カバー４３のそれぞれは、複数の分割体５０に分割されている。このため、前カバー４２及び後カバー４３のそれぞれの高さ寸法も容易に変更することができる。 Also, each of the front cover 42 and the rear cover 43 is divided into a plurality of divided bodies 50 . Therefore, the height dimension of each of the front cover 42 and the rear cover 43 can be easily changed.
　また、個々の部品が小型化されているため、空間形成体２２の組立作業を容易にすることができる。また、狭い昇降路１内での作業性を向上させることができる。 Also, since the individual parts are miniaturized, the assembly work of the space forming body 22 can be facilitated. In addition, workability in the narrow hoistway 1 can be improved.
