Description

本発明は、建屋の下階と上階との間に乗客コンベアとしてのエスカレータのトラスを設置する乗客コンベアの架設方法に関する。   The present invention relates to a passenger conveyor erection method in which an escalator truss as a passenger conveyor is installed between a lower floor and an upper floor of a building.

この種の従来の乗客コンベアの架設方法としては、例えば、トラスの上階側端部を支承する上階側トラス支承部の直上、又はその付近に揚重機等の吊上機を設置するとともに、トラスの下階側を支承する下階側トラス支承部の直上、又はその付近に門型吊上機を設置した後、上階の吊上機によりトラスの上階側を吊上げて、この上階側の端部を上階側トラス支承部よりトラスの上下厚み程度上方へ上昇させ、次いで、下階の門型吊上機によりトラスの下階側を下階側トラス支承部より多少上方に吊上げている。このようにしてトラス全体を設置箇所の上方に一旦配置した後、トラスの傾斜角度を設置時と同等の状態に保ちながらトラス全体を吊下ろして、トラスの上階側端部を上階側トラス支承部に取り付けるとともにトラスの下階側を下階側トラス支承部に取り付けるようにしたものがある。なお、建屋の梁が十分な強度を有する場合、上記の門型吊上機を下階の床上に設ける代わりに、建屋の梁にトラスの下階側を吊上げる吊上機を設置することもある。   As a method for installing this type of conventional passenger conveyor, for example, a hoisting machine such as a lifting machine is installed directly above or near the upper floor side truss support section for supporting the upper floor side end of the truss, After installing a portal-type lifting machine directly above or near the lower floor truss support that supports the lower floor of the truss, the upper floor of the truss is lifted by the upper floor lifting machine. The upper end of the truss is raised above the upper floor truss support by about the vertical thickness of the truss, and then the lower floor of the truss is lifted slightly above the lower floor truss support by the lower-floor portal type lifting machine. ing. After the entire truss is placed above the installation location in this way, the entire truss is suspended while maintaining the same angle of inclination of the truss as the installation. There is one that is attached to the support part and the lower floor side of the truss is attached to the lower floor truss support part. If the beam of the building has sufficient strength, it is possible to install a lifting machine that lifts the lower side of the truss to the beam of the building instead of installing the above-mentioned gate type lifting machine on the floor of the lower floor. is there.

しかしながら、上述した架設方法では、トラス全体を上下させる作業、すなわち長い重量物の揚重作業を要するため、吊上げ能力の大きい大型の吊上機を要し、上階および下階の各トラス支承部の直上またはその付近に吊上機を設置する際に運搬、固定および段取りに労力や時間がかかるとともに、上階での高所作業が難しく、かつ作業者の危険が伴うという問題がある。また、下階に設置する門型吊上機が大型であり特別仕様となるため、この門型吊上機をエスカレータ据付現場ごとに製作する必要があり、門型吊上機の製作費および取付費が高いという問題もある。   However, the above-described erection method requires the work of raising and lowering the entire truss, that is, the lifting work of a long heavy object, and therefore requires a large lifting machine having a large lifting capacity, and each truss support part on the upper floor and the lower floor. When installing a hoisting machine directly above or in the vicinity of it, there are problems that it takes labor and time to transport, fix and set up, and that it is difficult to work at high places on the upper floor and there is a danger to the operator. In addition, since the portal type lifting machine installed on the lower floor is large and has a special specification, it is necessary to manufacture this portal type lifting machine at each escalator installation site. Production costs and installation of the portal type lifting machine There is also the problem of high costs.

また、トラス全体を設置箇所の上方に一旦配置した後、トラスの傾斜角度を設置時と同等の状態に保ちながらトラス全体を吊下ろすことにより建屋の下階と上階との間に設置するようにしているため、トラスを上下方向に移動させる距離が長くなり作業効率の改善が要望されている。   Also, once the entire truss is placed above the installation location, the entire truss is suspended between the lower and upper floors of the building by suspending the entire truss while maintaining the same angle of inclination as the installation. Therefore, the distance for moving the truss in the up-and-down direction becomes long, and improvement in work efficiency is desired.

本発明は、上述した問題点に着目してなされたもので、その目的とするところは、建屋の下階と上階との間にトラスを迅速に設置できるとともに、その際の作業空間を縮小でき、かつ吊上機の小型化を図ることのできる乗客コンベアの架設方法を提供することにある。   The present invention has been made paying attention to the above-mentioned problems, and the object is to quickly install a truss between the lower floor and upper floor of the building and reduce the work space at that time. An object of the present invention is to provide a passenger conveyor erection method capable of reducing the size of a lifting machine.

上記目的を達成するため本発明の第1の特徴は、建屋の下階と上階との間に設置されるトラスと、このトラスの幅方向の両側に立設される欄干と、前記トラスに沿って周回移動可能となるように無端状に連結された複数の踏段とを有する乗客コンベアの架設方法であって、前記トラスを移動させる複数の移動手段を配置する工程と、前記下階側で前記トラスの下階側を牽引する牽引ロープを取り付ける工程と、前記牽引ロープを介して前記トラスの下階側を牽引することにより前記トラスを水平方向に移動させる工程と、前記下階に移動式吊上機を設置して前記トラスの下階側を吊上げ、下階側の前記移動手段を外す工程と、前記上階の床上に他の吊上機を設け、その吊上ロープを前記トラスの下階側に結ぶ工程と、前記トラスの上階側を上階レベルと同じレベルまで吊上げて上階側の前記移動手段を外す工程と、前記トラスの下階側を降ろして下階側トラス支承部に取付けるとともに、前記トラスの上階側端部を上階側トラス支承部に取付ける工程と、前記トラスの下階側および上階側の水平位置を調整する工程と、前記トラスの下階側および上階側の固定位置を調整する工程と、前記牽引ロープおよび前記各吊上機をそれぞれ撤去する工程と、を有することを要旨とする。   In order to achieve the above object, the first feature of the present invention is that a truss installed between a lower floor and an upper floor of a building, a balustrade erected on both sides in the width direction of the truss, and the truss A method of laying a passenger conveyor having a plurality of steps connected endlessly so as to be capable of circular movement along a step of disposing a plurality of moving means for moving the truss; Attaching a tow rope that pulls the lower floor side of the truss, moving the truss horizontally by pulling the lower floor side of the truss via the tow rope, and moving to the lower floor Installing a lifting machine to lift the lower floor side of the truss, removing the moving means on the lower floor side, providing another lifting machine on the floor of the upper floor, the lifting rope of the truss The process of tying to the lower floor and the upper floor of the truss Lifting up to the same level as the level and removing the moving means on the upper floor side, lowering the lower floor side of the truss and attaching it to the lower floor truss support part, and connecting the upper floor side end of the truss to the upper floor side Attaching to the truss support, adjusting the horizontal positions of the lower and upper floors of the truss, adjusting the fixed positions of the lower and upper floors of the truss, the tow rope and And a step of removing each of the hoisting machines.

本発明の乗客コンベアの架設方法では、建屋の下階と上階との間にトラスを迅速に設置できるとともに、その際の作業空間を縮小でき、かつ吊上機の小型化を図ることができ、したがって、乗客コンベアの架設時の作業効率を改善でき、乗客コンベア据付作業に要するコストを削減できるという効果がある。   In the passenger conveyor erection method of the present invention, a truss can be quickly installed between the lower floor and the upper floor of the building, the working space at that time can be reduced, and the lifting machine can be downsized. Therefore, it is possible to improve the work efficiency at the time of installing the passenger conveyor and to reduce the cost required for the passenger conveyor installation work.

本発明によれば、建屋の下階で牽引ロープを介してトラス下階側を牽引して移動手段で移動させることによりトラスの水平移動を行なった後、トラスの下階側および上階側を同時ではなく別々に上下させるようにしたことにより、吊上げ能力が比較的小さい小型な吊上機を用いることができ、各吊上機の運搬、固定および段取りが容易であり労力が少なくて済み、建屋の下階と上階との間にトラスを迅速に設置できる。また、トラスを設置箇所の上方に一旦配置した後にトラス全体を吊下ろす必要がないため、トラスを上下方向に移動させる距離を短くして作業空間を縮小できる。   According to the present invention, the lower floor side and the upper floor side of the truss are moved after the truss is horizontally moved by pulling the truss lower floor side via the pulling rope on the lower floor of the building and moving by the moving means. By raising and lowering separately rather than simultaneously, it is possible to use a small lifting machine with a relatively small lifting capacity, and it is easy to transport, fix and set up each lifting machine and requires less labor. A truss can be quickly installed between the lower and upper floors of the building. In addition, since it is not necessary to suspend the truss once after the truss has been disposed above the installation location, the working space can be reduced by shortening the distance for moving the truss in the vertical direction.

The truss 1 is installed between the lower floor 2 and the upper floor 3 of the building. A part of the balustrade 4 is erected.

下階2の床2aの所定位置には、トラス1の下部トラス1aを収容するピット5が設けられ、このピット5の底部に下部トラス1aを支承する下階側トラス支承部6が配設されている。この下階側トラス支承部6に取り付けた下部トラス1aの先端とこれに対向するピット壁部5aとの間には、比較的大きな間隙Gが設けられている。   A pit 5 for receiving the lower truss 1a of the truss 1 is provided at a predetermined position on the floor 2a of the lower floor 2, and a lower floor truss support portion 6 for supporting the lower truss 1a is disposed at the bottom of the pit 5. ing. A relatively large gap G is provided between the tip of the lower truss 1a attached to the lower floor side truss support portion 6 and the pit wall portion 5a facing the lower truss 1a.

上階3の床3aにはトラス1を設置するために開口部7が設けられ、上階3の床3aの縁部には、上部トラス1bを支承する上階側トラス支承部8が配設されている。上部トラス1bの先端底部には、図示しない吊りピースなどが工場出荷時に溶接等により取り付けられている。   An opening 7 is provided in the floor 3a of the upper floor 3 for installing the truss 1, and an upper floor side truss support section 8 for supporting the upper truss 1b is disposed at the edge of the floor 3a of the upper floor 3. Has been. A suspension piece (not shown) or the like is attached to the bottom of the tip of the upper truss 1b by welding or the like at the time of factory shipment.

本実施の形態のエスカレータの架設方法では、下階2の床2a上に設けられ、トラス1を移動させる移動手段、例えば台車9,10と、下階2の柱等の固定体11に取り付けられ、牽引ロープ12を介してトラス1の下階側を牽引する牽引ウインチ13と、下階2に移動可能に設けられ、トラス1の下階側を吊上げる移動式吊上機、例えば門型吊上機14と、上階3の床3a上に設置され、トラス1の上階側を吊上げる他の吊上機15とが用いられている。   In the escalator installation method of the present embodiment, the escalator is installed on the floor 2a of the lower floor 2 and is attached to moving means for moving the truss 1, for example, the carriages 9 and 10 and the fixed body 11 such as the pillar of the lower floor 2. A tow winch 13 that pulls the lower floor side of the truss 1 via the tow rope 12 and a movable lifting machine that is movably provided on the lower floor 2 and lifts the lower floor side of the truss 1, for example, a gate-type suspension An upper machine 14 and another lifting machine 15 that is installed on the floor 3a of the upper floor 3 and lifts the upper floor side of the truss 1 are used.

下階2に移動可能に設けられる門型吊上機14は、ピット5の両側に跨った状態で下部トラス1aを吊上げ可能である。図2に示すように、上階3に設けられる吊上機15は、上階3の床3aに固設される支持部16に搭載され、吊上ロープ17を巻取る巻上部本体18と、支持部16に搭載されて上階3の床3aの縁部より突出し、吊上ロープ17が巻掛けられる滑車19と、巻上部本体18に油圧油を供給する油圧ユニット20とから構成されている。この吊上機15の支持部16は上階3の床3aにアンカボルト21で固定されている。滑車19が上階3の床3aの縁部より突出することにより、滑車19から垂下する吊上ロープ17が上階側トラス支承部8と干渉することが防止されている。なお、上階3の吊上機15は、例えば、商標名が油圧チルホールなどと称される周知のものを用いることができる。   The gate type lifting machine 14 provided movably on the lower floor 2 can lift the lower truss 1 a while straddling both sides of the pit 5. As shown in FIG. 2, the lifting machine 15 provided on the upper floor 3 is mounted on a support portion 16 fixed to the floor 3 a of the upper floor 3, and a winding upper body 18 that winds the lifting rope 17, The pulley 19 is mounted on the support 16 and protrudes from the edge of the floor 3 a of the upper floor 3, on which the lifting rope 17 is wound, and the hydraulic unit 20 that supplies hydraulic oil to the winding upper body 18. . The support 16 of the lifting machine 15 is fixed to the floor 3a of the upper floor 3 with anchor bolts 21. Since the pulley 19 protrudes from the edge of the floor 3 a of the upper floor 3, the suspension rope 17 hanging from the pulley 19 is prevented from interfering with the upper floor side truss support portion 8. As the lifting machine 15 on the upper floor 3, for example, a well-known machine whose trade name is referred to as a hydraulic chill hall can be used.

そして、本実施の形態にあっては、図1に示す作業手順にしたがってトラス1を建屋の下階2と上階3との間に設置するようになっている。すなわち、手順S1として、図3に示すように、下部トラス1a,上部トラス1bおよび中間トラス1cを下階2に搬入してトラス1を組立て、下階2の床2a上に台車9,10をセットした後、下部トラス1aおよび中間トラス1c間の屈折部を台車9に搭載するとともに、上部トラス1bの端部を他の台車10に搭載した後、手順S2として、下階2の固定体11に牽引ウインチ13を取り付けて、この牽引ウインチ13で牽引ロープ12を介してトラス1の下階側(下部トラス1a)を固定体11の方向に牽引することにより、図4に示す吊上位置までトラス1を下階2の床2a上で水平移動させる。   And in this Embodiment, the truss 1 is installed between the lower floor 2 and the upper floor 3 of a building according to the operation | work procedure shown in FIG. That is, as step S1, as shown in FIG. 3, the lower truss 1a, the upper truss 1b and the intermediate truss 1c are carried into the lower floor 2 to assemble the truss 1, and the carriages 9, 10 are placed on the floor 2a of the lower floor 2. After the setting, the bending portion between the lower truss 1a and the intermediate truss 1c is mounted on the carriage 9, and the end of the upper truss 1b is mounted on the other carriage 10, and then the fixed body 11 on the lower floor 2 is set as step S2. A tow winch 13 is attached to the hoist, and the lower floor side (lower truss 1a) of the truss 1 is pulled in the direction of the fixed body 11 through the tow rope 12 with the tow winch 13 to the lifting position shown in FIG. The truss 1 is moved horizontally on the floor 2a of the lower floor 2.

次いで、手順S4として、図4に示すように、下階2に門型吊上機14を設置しトラス1の下階側(下部トラス1a)を吊上げて台車9を外し、トラス1の下階側をピット5の直上まで移動させる。手順S5として、上階3の床3a上に設けた吊上機15の吊上ロープ17を上部トラス1bの先端底部の吊りピースに結び、手順S6として、図5に示すように、吊上機15でトラス1の上階側(上部トラス1b)を上階レベルとほぼ同じレベルまで吊上げて台車10を外す。このとき牽引ウインチ13を操作して牽引ロープ12を送出したり巻取ったりすることによりトラス1の下階側に対して図5の右側への張力を付与しながら、上階3の吊上機15でトラス1の上階側を吊上げる。これにより、上階3の吊上機15でトラス1の上階側を吊上げる動作と、下階2の牽引ウインチ13でトラス1の下階側を図5の右側へ牽引する動作とのバランスを取りながら、上階3の吊上機15でトラス1の上階側、すなわち図5の左側を吊上げた状態でトラス1が図5の左側へ移動し過ぎることを抑制している。   Next, as step S4, as shown in FIG. 4, a gate type lifting machine 14 is installed on the lower floor 2, the lower floor side (lower truss 1a) of the truss 1 is lifted, the carriage 9 is removed, and the lower floor of the truss 1 Move side to just above pit 5. As step S5, the hoisting rope 17 of the hoisting machine 15 provided on the floor 3a of the upper floor 3 is tied to the hoisting piece at the bottom of the tip of the upper truss 1b, and as the procedure S6, as shown in FIG. 15, the upper floor side of the truss 1 (upper truss 1 b) is lifted to a level substantially equal to the upper floor level, and the carriage 10 is removed. At this time, the towing winch 13 is operated to send out or wind up the towing rope 12 so as to apply the rightward tension in FIG. 15 lift the upper floor side of truss 1. Thus, the balance between the operation of lifting the upper floor side of the truss 1 with the lifting machine 15 on the upper floor 3 and the operation of pulling the lower floor side of the truss 1 to the right side in FIG. In the state where the upper floor side of the truss 1, that is, the left side of FIG. 5 is lifted by the lifting machine 15 of the upper floor 3, the movement of the truss 1 to the left side of FIG. 5 is suppressed.

次いで、手順S7として、図6に示すように、トラス1の下階側をピット5内に降ろした後、図7に示すように、牽引ロープ12の張力を緩めながら上階3の吊上機15でトラス1の上階側を吊上げて上部トラス1bの先端を上階側トラス支承部8に取り付けるとともに、下部トラス1aをさらに降ろしてピット5内の下階側トラス支承部6に取り付け、手順S8として下部トラス1aおよび上部トラス1bの水平位置を調整し、手順S9として下部トラス1aおよび上部トラス1bの上下固定位置を調整した後、手順S10として牽引ウインチ13および各吊上機14,15を撤去して、下部トラス1aの先端とピット壁部5aとの間隙Gを覆う鉄板等を設ける。   Next, as step S7, as shown in FIG. 6, after lowering the lower floor side of the truss 1 into the pit 5, as shown in FIG. 15, the upper floor side of the truss 1 is lifted and the tip of the upper truss 1 b is attached to the upper floor truss support portion 8, and the lower truss 1 a is further lowered and attached to the lower floor truss support portion 6 in the pit 5. After adjusting the horizontal positions of the lower truss 1a and the upper truss 1b as S8, and adjusting the vertical fixing positions of the lower truss 1a and the upper truss 1b as procedure S9, the towing winch 13 and the lifting machines 14, 15 are installed as procedure S10. It removes and the iron plate etc. which cover the clearance gap G between the front-end | tip of the lower truss 1a and the pit wall part 5a are provided.

このように構成した本実施の形態では、下階2で組立てたトラス1を台車9,10に搭載した状態で牽引ウインチ13で牽引することにより水平移動を行なった後、トラス1の下階側および上階側を同時ではなく別々に吊上げるようにしたので、トラス1全体を同時に吊上げる従来の場合と比べて、比較的小さい小型な吊上機14,15を用いることができ、これらの吊上機14,15の運搬、固定および段取りが容易であり労力が少なくて済み、下階2と上階3との間にトラス1を迅速に設置できる。特に、高所作業を要する上階3の吊上機15が小型であるので、上階3の床3a上で吊上機15の設置や取扱いを容易に、かつ安全に行なうことができる。さらに、上階3の吊上機15でトラス1の上階側を吊上げる際に、牽引ウインチ13の牽引によりトラス1が図5の左側へ移動し過ぎることを抑制しているので、この点でもトラス1の吊上作業を安全にかつ正確に行なうことができる。   In this embodiment configured as described above, the truss 1 assembled on the lower floor 2 is horizontally moved by being pulled by the towing winch 13 in a state where the truss 1 is mounted on the carts 9 and 10, and then the lower floor side of the truss 1. Since the upper floor side is lifted separately instead of simultaneously, relatively small and small lifting machines 14 and 15 can be used as compared with the conventional case of lifting the entire truss 1 simultaneously. The lifting machines 14 and 15 can be easily transported, fixed, and set up, requiring less labor, and the truss 1 can be quickly installed between the lower floor 2 and the upper floor 3. In particular, since the lifting machine 15 on the upper floor 3 requiring work at a high place is small, the lifting machine 15 can be easily and safely installed and handled on the floor 3a of the upper floor 3. Further, when the upper floor side of the truss 1 is lifted by the lifting machine 15 on the upper floor 3, the truss 1 is prevented from moving too far to the left in FIG. However, the lifting work of the truss 1 can be performed safely and accurately.

また、本実施の形態では、吊上機14,15が小型であり特別仕様とする必要がないため、各吊上機14,15を異なるエスカレータ据付現場で共用することができ、吊上機14,15の製作費および取付費を削減できる。   In the present embodiment, since the lifting machines 14 and 15 are small and do not need to have special specifications, the lifting machines 14 and 15 can be shared at different escalator installation sites. , 15 production costs and installation costs can be reduced.

また、本実施の形態では、トラス1を設置箇所の上方に一旦配置した後にトラス1全体を吊下ろす必要がないので、トラス1を上下方向に移動させる距離を短くして作業空間を縮小できる。   Further, in the present embodiment, it is not necessary to suspend the truss 1 once after the truss 1 is arranged above the installation location, so that the working space can be reduced by shortening the distance for moving the truss 1 in the vertical direction.

また、本実施の形態では、ピット5の寸法を大きくして下部トラス1aの先端と壁部5aとの間隙Gを比較的大きく設定したので、図6に示すように上部トラス1bの先端を上階側トラス支承部8に取り付ける際に、下部トラス1aの先端下部が壁部5aとの干渉することがなくて済み、円滑にトラス1を設置できる。さらに、下部トラス1aの先端下部を削り落とすことによっても同様の効果を得ることができる。   In the present embodiment, the size of the pit 5 is increased to set the gap G between the tip of the lower truss 1a and the wall 5a to be relatively large, so that the tip of the upper truss 1b is raised as shown in FIG. When attaching to the floor side truss support part 8, the lower end of the lower truss 1a does not need to interfere with the wall part 5a, and the truss 1 can be installed smoothly. Further, the same effect can be obtained by scraping off the lower end of the lower truss 1a.

また、本実施の形態では、上階3の床3a上に吊上機15を設置して用いるようにしたので、建屋の梁などの吊元がない場合や吊元の強度が十分でない場合、また建屋の天井高さに余裕がない場合にも適用可能であり、門型吊上機14も同様である。   In the present embodiment, since the lifting machine 15 is installed and used on the floor 3a of the upper floor 3, when there is no suspension source such as a beam of the building or when the strength of the suspension source is not sufficient, Further, the present invention can be applied to a case where the ceiling height of the building is not sufficient, and the same applies to the gate type lifting machine 14.

なお、上記実施の形態にあっては、ピット5の底部に下階側トラス支承部6をあらかじめ配設する場合を例示したが、本発明はこれに限らず、トラス1の下階側を設置した後、このトラス1の下階側を支承するトラス支承部を後付で設けることもできる。   In the embodiment described above, the case where the lower floor truss support 6 is disposed in advance at the bottom of the pit 5 is exemplified, but the present invention is not limited to this, and the lower floor of the truss 1 is installed. Then, a truss support part for supporting the lower floor side of the truss 1 can be provided later.

また、上記実施の形態にあっては、下階2にピット5を設けた場合を例示したが、下階2にピット5を設ける代わりに、下階2に支持梁を設けてこの支持梁に下階側のトラス支承部を設けることもでき、この場合には、トラス1の設置作業と支持梁の取付作業とを平行して行なうことができる。   Moreover, in the said embodiment, although the case where the pit 5 was provided in the lower floor 2 was illustrated, instead of providing the pit 5 in the lower floor 2, a support beam is provided in the lower floor 2 and this support beam is attached to this support beam. A truss support part on the lower floor side can also be provided. In this case, the installation work of the truss 1 and the installation work of the support beam can be performed in parallel.

また、上記実施の形態にあっては、下階2に台車9,10をセットした場合を例示したが、下部トラス1aおよび中間トラス1c間の屈折部の下に台車9を取り付け、上部トラス1bの端部の下に他の台車10を取り付けることもでき、さらに、台車9、10の代わりに、他の移動手段を設けてもよい。また、下階2に躯体や部屋等が設けられ、トラス1の設置部分の下方が塞がれている場合には、上記の躯体や部屋等の上方に斜路を形成して、この斜路上を、上記の移動手段を取り付けたトラス1を移動させることもできる。   Moreover, in the said embodiment, although the case where the trolley | bogies 9 and 10 were set to the lower floor 2 was illustrated, the trolley | bogie 9 was attached under the bending part between the lower truss 1a and the intermediate truss 1c, and upper truss 1b Another carriage 10 can be attached under the end of the carriage, and other moving means may be provided instead of the carriages 9 and 10. In addition, when the lower floor 2 is provided with a frame, a room, and the like, and the lower part of the truss 1 is blocked, a ramp is formed above the frame, the room, and the like. The truss 1 to which the above moving means is attached can be moved.

また、上記実施の形態にあっては、吊上機15の支持部16を上階3の床3aにアンカボルト21により固定したが、支持部16を建屋の鉄骨等の躯体に溶接付けしてもよく、さらに、支持部16を設けることなく、巻上部本体18および滑車19を上階3の床3aなどに直接取り付けてもよい。   Moreover, in the said embodiment, although the support part 16 of the lifting machine 15 was fixed to the floor 3a of the upper floor 3 with the anchor bolt 21, the support part 16 was welded to housings, such as a steel frame of a building. Furthermore, the winding upper body 18 and the pulley 19 may be directly attached to the floor 3a of the upper floor 3 without providing the support portion 16.
