Description

本発明は高層建物の解体システム及び解体方法に係り、高層建物の外部養生設備の降下動作と、解体廃材を搬出する揚重設備の降下動作とを独立して機能させることで、解体作業の進捗に応じた効率のよい建物の解体作業を実現した高層建物の解体システム及び解体方法に関する。 The present invention relates to a dismantling system and a dismantling method for a high-rise building, wherein the lowering operation of the external curing equipment of the high-rise building and the lowering operation of the lifting equipment for carrying out the dismantled waste material are independently operated, thereby the progress of the dismantling work. The present invention relates to a demolition system and a demolition method for a high-rise building that realizes efficient demolition work for a building.
近年、都心部において、建て替えを含めた地域再開発等のために既存の高層建物の解体工事の要請がある。都心部では騒音等が発生する解体工事は、特に周辺環境に配慮して効率的に行う必要がある。そのため、既存建物の全体、たとえば屋上部分を仮設屋根等で、建物の解体作業を行う階の上下数階の外周部分を養生パネル等で覆った閉鎖空間内での解体作業が種々実施されている。このような解体工事では、仮設屋根や建物外周の養生足場や防音パネルの設備全体を建物の解体の進捗に合わせて降下させる昇降装置を備えている場合が多い。 In recent years, there has been a demand for demolition work of existing high-rise buildings in urban areas for regional redevelopment including rebuilding. In the city center, the dismantling work that causes noise, etc. needs to be carried out efficiently in consideration of the surrounding environment. Therefore, various dismantling works are being carried out in a closed space where the entire existing building, for example, the rooftop part is covered with a temporary roof, and the outer peripheral parts of the upper and lower floors where the building is dismantled are covered with curing panels. .. In such demolition work, in many cases, a temporary roof, a curing scaffold on the outer periphery of the building, and a lifting device that lowers the entire equipment of the soundproof panel according to the progress of the demolition of the building are provided.
この用途に用いられる昇降装置は各種開発されているが、特許文献1に開示された昇降フレームユニットは、互いに上下方向に相対移動自在な支柱フレーム、内フレーム、外フレームとで構成され、たとえば外フレームに駆動装置により回転可能なネジロッド(スクリューロッド)が設けられ、内フレームにネジロッドに螺合し、ネジロッドの回転により回転不能にフレーム内を昇降するナットが設けられている。ネジロッドの所定方向への回転によって両フレームの所定ストロークの降下動作と、支持体(建物躯体等)への支持動作とを繰り返すことで、昇降装置の配備された建物部位を解体の進捗に従って降下させるようになっている。 Although various lifting devices used for this purpose have been developed, the lifting frame unit disclosed in Patent Document 1 is composed of a column frame, an inner frame, and an outer frame that are relatively movable in the vertical direction. The frame is provided with a screw rod (screw rod) that can be rotated by a drive device, and the inner frame is provided with a nut that is screwed onto the screw rod and that is rotated in the frame so as to be unrotatable. By repeating the lowering motion of both frames by a predetermined stroke by the rotation of the screw rod and the supporting motion to the support (building frame etc.), the building part where the lifting device is installed is lowered according to the progress of the dismantling. It is like this.
また、特許文献1に開示された昇降フレームユニットを、建物の外周に確実に固定するための固定装置も提案されている(特許文献2)。特許文献2に開示された固定装置は、建物の一部に固定される鋼材を組み立ててなる筐体と、筐体から先端側が建物の外部に張り出してピンが配設されたブラケットとを備え、昇降装置側に設けられた嵌合部がピンに着脱自在に嵌合することで、昇降装置を支持固定するようになっている。これにより昇降装置は、確実、迅速に建物側に固定支持される。 Further, a fixing device for securely fixing the elevating frame unit disclosed in Patent Document 1 to the outer periphery of a building has also been proposed (Patent Document 2). The fixing device disclosed in Patent Document 2 includes a housing formed by assembling a steel material that is fixed to a part of a building, and a bracket on which a tip side of the housing projects to the outside of the building and pins are arranged. The fitting portion provided on the lifting device side is detachably fitted to the pin to support and fix the lifting device. As a result, the lifting device is securely and quickly fixedly supported on the building side.

ところで、仮設屋根で建物上部が覆われている場合には、躯体を解体した際に発生する廃材を搬出するためのタワークレーン等を設置することができない。このため、解体工事を行っている階から地上階まで解体廃材を下ろすことができる搬出経路を建物内部に設ける必要がある。この場合、一般にはすべての階の同一位置の床スラブの一部を撤去して開口を設け、建物の上下方向に貫通させた荷降ろしシャフト(立坑)とし、その荷降ろしシャフトを利用して解体廃材を上階から地上階(外部への搬出階)まで下ろす等の方策がとられている。この場合、解体作業を行っている階では解体廃材を荷降ろしシャフトまで横引き移動する作業が発生し、引き続き荷降ろしシャフト内を下方に降下させる作業が発生する。これらの作業を一貫して行うために、テルハ(横行クレーン)等の設備が設置されている。このときテルハの横行レールとなる桁(ガーダー)のスパンは、建物全体を覆うように、建物の外周で特許文献1,2に開示された昇降装置、固定装置で支持された仮設屋根のスパンと合わせて架設する必要がある。このため、平面積が大きい建物では、横行レールのスパンが大きくなってしまい、設置できるクレーン(揚重設備)の吊り上げ性能が制限されてしまう等の問題がある。 By the way, when the upper part of the building is covered by the temporary roof, it is not possible to install a tower crane or the like for carrying out waste materials generated when the building is disassembled. For this reason, it is necessary to provide a delivery route inside the building from which the demolition waste material can be lowered from the floor where the demolition work is being performed to the ground floor. In this case, generally, a part of the floor slab at the same position on all floors is removed and an opening is provided to form an unloading shaft (vertical shaft) that penetrates the building in the vertical direction, and the unloading shaft is used to dismantle the building. Measures such as lowering waste materials from the upper floor to the ground floor (the floor to which the material is carried out to the outside) are taken. In this case, on the floor where the dismantling work is being performed, a work of unloading the dismantled waste material is performed to laterally pull it to the shaft, and a work of subsequently lowering the interior of the unloading shaft is generated. In order to perform these operations consistently, equipment such as Telha (transverse crane) is installed. At this time, the span of the girder that becomes the traverse rail of Telha is the span of the temporary roof supported by the lifting device and the fixing device disclosed in Patent Documents 1 and 2 on the outer periphery of the building so as to cover the entire building. It is necessary to install them together. Therefore, in a building with a large flat area, the span of the traverse rail becomes large, and the lifting performance of the crane (lifting equipment) that can be installed is limited.
また、テルハの横行レールを荷降ろしシャフト上に独立して架設した場合、各階での解体作業が完了するごとに横行レールを支持する支持部材を既存柱等に取り付けて、各階毎に横行レールの設置、解体を繰り返して行う付加的な作業が発生し、解体作業の効率化が図れない。そこで、本発明の目的は上述した従来の技術が有する問題点を解消し、建物の解体工事を行う際、建物を覆う仮設屋根の昇降装置の降下動作と、解体廃材を建物外に搬出する搬出装置の降下動作とを独立して連続稼動できるようにした高層建物の解体システムと解体方法を提供することにある。 In addition, when the traverse rail of Telha is unloaded and installed independently on the shaft, a support member that supports the traverse rail is attached to the existing pillar etc. each time the dismantling work on each floor is completed, and the traverse rail of each floor is installed. The additional work of repeatedly installing and dismantling occurs, and the efficiency of the dismantling work cannot be improved. Therefore, an object of the present invention is to solve the problems of the above-described conventional technology, and when performing the dismantling work of a building, the lowering operation of the lifting device of the temporary roof covering the building and the unloading of the dismantled waste material to the outside of the building. An object of the present invention is to provide a dismantling system and a dismantling method for a high-rise building, which enables continuous operation independently of the descending operation of the device.

図1は、本発明の高層建物の解体システムを用いて既存の高層建物1(以下、建物1)を上階から順次解体していく解体作業の状態を模式的に示した説明図である。同図には、すでに屋上から数階が解体された状態が示されている。解体対象の建物1では、N階に配備された解体用重機2による(N+1)階の解体作業が進行している。 FIG. 1 is an explanatory view schematically showing a state of dismantling work in which an existing high-rise building 1 (hereinafter referred to as building 1) is sequentially dismantled from the upper floor using the high-rise building dismantling system of the present invention. The figure shows a state in which several floors have already been demolished from the roof. In the building 1 to be dismantled, the dismantling work on the (N+1)th floor by the dismantling heavy equipment 2 deployed on the Nth floor is in progress.
本発明の高層建物の解体システム10の昇降装置100は、建物の外周養生設備20を解体作業の進捗に従って降下させる外周昇降装置110と、解体廃材を搬出するための揚重設備30を解体作業の進捗に従って降下させる内部昇降装置120とで構成されている。以下、上述した各設備の構成、動作について説明する。なお、本発明の実施形態において、外周昇降装置110と内部昇降装置120は設置位置、用途により名称を区別しているが、それらの構成、昇降動作は同一である。 The lifting device 100 of the dismantling system 10 for a high-rise building of the present invention includes an outer circumference lifting device 110 for lowering the outer circumference curing equipment 20 of a building according to the progress of the dismantling work, and a lifting equipment 30 for carrying out dismantled waste materials. It is composed of an internal elevating device 120 that descends according to the progress. Hereinafter, the configurations and operations of the above-mentioned facilities will be described. In the embodiment of the present invention, the outer circumference lifting device 110 and the inner lifting device 120 are distinguished in name by installation position and use, but their configurations and lifting operations are the same.
[外周養生設備と外周昇降装置]
建物の外周は、建物の複数本の既存柱に設置された外周支持ユニットに支持された複数基の外周昇降装置110と、外周養生設備20として複数基の外周昇降装置110の外周面に壁つなぎアンカー21を介して立設された外部養生足場22と、外部養生足場22の外面に取り付けられた防音パネル23と、一列に並んで配置された外周昇降装置110の上端を繋ぐように架設された支持梁24で支持され、建物の上部を覆うトラス構造フレーム25からなる仮設屋根26とが配置されている。
[Outer peripheral curing equipment and outer peripheral lifting device]
The outer periphery of the building is connected to the outer peripheral elevating devices 110, which are supported by outer peripheral supporting units installed on a plurality of existing pillars of the building, and the outer peripheral elevating devices 110 serving as outer peripheral curing equipment 20, by connecting walls to the outer peripheral surfaces. The external curing scaffold 22 erected via the anchor 21, the soundproof panel 23 attached to the outer surface of the external curing scaffold 22, and the outer peripheral elevating device 110 arranged side by side in a row were installed so as to connect to each other. A temporary roof 26 composed of a truss structure frame 25 that is supported by the support beams 24 and covers the upper part of the building is arranged.
本発明で使用される昇降装置100(外周昇降装置110、内部昇降装置120に共通する内容についての説明では、以下、単に昇降装置100と記す。)は、特許文献1に開示された装置と同等機能を有する公知の装置である。すなわち、駆動伝達機構であるネジロッドが外フレームに、ネジロッドと螺合するナットが内フレームに回転不能に昇降可能に保持されている。外フレームに組み込まれたネジロッドを電動モータで回転させることでネジロッドを保持する外フレームとナットを保持する内フレームの相対移動を制御し、昇降装置の外フレームが支持する架台等(本発明では外周養生設備、揚重設備)を所定のストロークで昇降する。昇降装置100に含まれる昇降機構としては、ネジロッドとナットとの組み合わせの他、所定ストロークでステップロッドに支持をとりながら昇降可能なセンターホールタイプの油圧ジャッキ等を利用することもできる。 The lifting device 100 used in the present invention (in the description of the contents common to the outer circumference lifting device 110 and the inner lifting device 120, hereinafter, simply referred to as the lifting device 100) is equivalent to the device disclosed in Patent Document 1. It is a known device having a function. That is, a screw rod that is a drive transmission mechanism is held by the outer frame, and a nut that is screwed with the screw rod is held by the inner frame so as to be non-rotatably liftable. By rotating the screw rod incorporated in the outer frame with an electric motor, relative movement of the outer frame holding the screw rod and the inner frame holding the nut is controlled, and a frame or the like supported by the outer frame of the elevating device (in the present invention, the outer circumference). The curing equipment and lifting equipment) are moved up and down with a predetermined stroke. As the elevating mechanism included in the elevating device 100, a combination of a screw rod and a nut, or a center hole type hydraulic jack capable of elevating while supporting the step rod with a predetermined stroke may be used.
昇降装置100は、昇降時に反力を支持体(本発明では建物躯体)に負担させることで装置自体を昇降させるため、本発明のような場合には、昇降装置100の昇降時(解体作業では降下動作が基本となる。)の反力を支持体としての建物の既存柱等に確実に支持させる支持ユニット130,140で装置本体を支持することが重要である。 The elevating device 100 elevates and lowers the device itself by applying a reaction force to the support body (building frame in the present invention) during elevating and lowering. Therefore, in the case of the present invention, during elevating the elevating device 100 (in the demolition work, It is important to support the main body of the apparatus by the support units 130 and 140 that surely support the reaction force of (the descending operation) on the existing pillars of the building as a support.
たとえば、本発明に用いられる外周昇降装置110の場合では、図1に示したように、N+1階の解体を行う際、装置の内フレームと外フレームは、下階(N階、(N−1)階)の2箇所の外周支持ユニット130で独立して支持される。さらに解体された(N+1)階から1階分を降下する時には新たな支持ユニット(図示せず)が、階下((N−2)階)に設けられ、(N−2)階を含めた3階分の支持ユニット間において、内フレームと外フレームの支持位置を盛り替えるようにして、装置の内フレーム、外フレームの降下動作、支持動作とが繰り返され1階分が降下する。N階の支持ユニットは撤去され、昇降装置は、その下階((N−1)階、(N−2)階)の2箇所の外周支持ユニット130で支持される。 For example, in the case of the outer peripheral lifting device 110 used in the present invention, as shown in FIG. 1, when disassembling the N+1 floor, the inner frame and the outer frame of the device are lower floors (N floor, (N-1 ) Floors) are independently supported by two outer peripheral support units 130. Further, when descending one floor from the dismantled (N+1) floor, a new support unit (not shown) is provided in the lower floor ((N-2) floor), including the (N-2) floor. Between the support units of the floors, the support positions of the inner frame and the outer frame are exchanged, and the lowering operation and the supporting operation of the inner frame and the outer frame of the apparatus are repeated to lower the first floor. The support unit on the Nth floor is removed, and the lifting device is supported by two outer peripheral support units 130 on the lower floors ((N-1)th floor and (N-2)th floor).
図2は、図1に示した解体システムの一部の平面レイアウトを模式的に示した平面図である。図1、2に示したように、外部養生足場22と仮設屋根26とは既存の外周柱3の配列に倣って所定間隔に配設された複数基の外周昇降装置110によって支持されている。各外周昇降装置110の降下量は、外部養生足場22と仮設屋根26とが捩れたりせずに安定した状態で水平を保持して降下するように、図示しない制御手段によってネジロッドの回転速度(回転量)が同期制御されている。なお、外部養生足場22と仮設屋根26の総重量や重量バランスに応じて、外周昇降装置110は外周柱3の配置を考慮して複数スパン間隔で配置したり、適正な支点位置を設定することが好ましい。 FIG. 2 is a plan view schematically showing a planar layout of a part of the disassembly system shown in FIG. As shown in FIGS. 1 and 2, the outer curing scaffold 22 and the temporary roof 26 are supported by a plurality of outer peripheral elevating devices 110 arranged at predetermined intervals in accordance with the existing arrangement of the outer peripheral columns 3. The descent amount of each outer circumference elevating device 110 is controlled by a control means (not shown) so that the outer curing scaffolding 22 and the temporary roof 26 can be lowered horizontally while maintaining a stable state without being twisted. Quantity) is controlled synchronously. It should be noted that, depending on the total weight and weight balance of the external curing scaffold 22 and the temporary roof 26, the outer peripheral elevating device 110 should be arranged at a plurality of span intervals in consideration of the arrangement of the outer peripheral pillars 3 or set an appropriate fulcrum position. Is preferred.
外部養生足場22と仮設屋根26とを支持する外周昇降装置110は各階の平面同位置に配置されている外周柱3に2箇所の外周支持ユニット130を介して固定保持されている。外周支持ユニットは、図2に示したように、外周柱3の外周面を囲むように取り付けられた、平面視して略ロ字形をなす形鋼組立材からなる。外周昇降装置110を外周柱3に固定保持する各外周支持ユニットはパーツ化され、外周昇降装置110の降下作業に合わせて、対象の外周柱3の所定位置に迅速に取り付けられるようになっている。一方、外周柱3には外周支持ユニットの取付位置に対応した位置にブラケット(図示せず)が取り付けられている。これにより、パーツ化された外周支持ユニット130をブラケットに載置し、部材同士をボルト接合することにより簡単、迅速に所定位置に組み付けることができる。 The outer peripheral elevating device 110 that supports the outer curing scaffold 22 and the temporary roof 26 is fixedly held to the outer peripheral pillars 3 arranged at the same position on the floor of each floor via the outer peripheral support units 130 at two locations. As shown in FIG. 2, the outer peripheral support unit is formed of a shaped steel assembly material which is attached so as to surround the outer peripheral surface of the outer peripheral column 3 and which has a generally square V shape in plan view. Each outer peripheral support unit for fixing and holding the outer peripheral elevating device 110 to the outer peripheral pillar 3 is made into parts, and can be quickly attached to a predetermined position of the target outer peripheral pillar 3 in accordance with the lowering work of the outer peripheral elevating device 110. .. On the other hand, a bracket (not shown) is attached to the outer peripheral post 3 at a position corresponding to the attachment position of the outer peripheral support unit. As a result, the outer peripheral support unit 130, which has been made into parts, is placed on the bracket, and the members are bolted to each other, so that the parts can be easily and quickly assembled at the predetermined positions.
[揚重設備と内部昇降手段]
本発明では、上述したように、解体時に発生する鉄骨、コンクリートガラ、鉄筋等の解体廃材を建物外に搬出するために、建物の内部に荷降ろしシャフト5が設けられている。荷降ろしシャフト5は、たとえば本実施形態では図1,2に示したように、4本の隣接した内部柱6で囲まれた範囲のスラブを切り取って開口7とし、建物1内の最上階から廃材の搬出を行う階(以下、搬出階と記す。)までの各階の同一箇所に開口7を設けることで上下に貫通させたものである。
[Lifting equipment and internal lifting means]
In the present invention, as described above, the unloading shaft 5 is provided inside the building in order to carry out dismantled waste materials such as steel frames, concrete debris, and reinforcing bars generated during dismantling to the outside of the building. In the unloading shaft 5, for example, in the present embodiment, as shown in FIGS. 1 and 2, a slab in a range surrounded by four adjacent inner columns 6 is cut out to form an opening 7, and the unloading shaft 5 is opened from the top floor in the building 1. An opening 7 is provided at the same location on each floor up to the floor where the waste material is to be carried out (hereinafter referred to as the carry-out floor), so that the material is vertically penetrated.
さらに荷降ろしシャフト5の各階の開口7から廃材を降下させるための揚重設備30として本実施形態ではテルハ(横行クレーン)が設置されている。このテルハ30は開口7の四隅に位置する内部柱6に取り付けられた内部支持ユニット140に支持された、内部昇降装置120の上端に架設された支持ビーム32に支持されたI形鋼等からなる横行レール33と、横行レール33に沿って走行可能なホイスト34とから構成されている。横行レール33は開口7の上方で開口7の両端から所定長さが張り出すように設置されているため、解体廃材を吊ったホイスト34を横行レール33に沿って走行させることで、図1に白矢印で示したように、解体作業を行っている階(解体作業階)で発生した解体廃材を荷降ろしシャフト5まで横引き移動し、さらに荷降ろしシャフト5を通じて搬出階まで降下させることができる。 Further, in the present embodiment, a telha (transverse crane) is installed as a lifting facility 30 for lowering waste material from the opening 7 on each floor of the unloading shaft 5. The Telha 30 is made of I-shaped steel or the like supported by a support beam 32 that is supported by internal support units 140 that are attached to the internal columns 6 located at the four corners of the opening 7, and that is supported by a support beam 32 that is installed on the upper end of the internal lifting device 120. The traverse rail 33 and a hoist 34 capable of traveling along the traverse rail 33 are configured. Since the traverse rail 33 is installed above the opening 7 so as to project a predetermined length from both ends of the opening 7, by running the hoist 34 suspending the dismantled waste material along the traverse rail 33, as shown in FIG. As indicated by the white arrow, it is possible to unload the demolition waste material generated on the floor (demolition work floor) where the demolition work is being carried out, laterally pull it to the shaft 5, and further to the unloading floor through the unloading shaft 5. ..
内部昇降装置120は、支持するテルハ30全体を所定のストロークで昇降することができる。4基の内部昇降装置120の降下量は、支持ビーム32,横行レール33が捩れたりせずに安定した状態で水平を保持して降下するように、図示しない制御手段によって各ネジロッドの回転速度(回転量)が同期制御されている。本発明では、内部昇降装置120と外周昇降装置110とは、ともに単一の制御装置により独立してネジロッドの回転制御を行うことができる。 The internal elevating device 120 can elevate and lower the supported Telha 30 in a predetermined stroke. The descending amounts of the four internal elevating devices 120 are controlled by the control means (not shown) so that the supporting beams 32 and the traverse rails 33 are maintained in a horizontal state in a stable state without being twisted and are lowered ( The rotation amount) is synchronously controlled. In the present invention, both the internal elevating device 120 and the outer elevating device 110 can independently control the rotation of the screw rod by a single control device.
ここで、内部支持ユニット140の構成について、図3各図を参照して説明する。内部支持ユニット140は、開口7の四隅に位置する内部柱6に取り付けられるため、内部昇降装置120の設置位置と内部柱6の断面形状との関係を考慮した平面形状からなる。すなわち図3(a)に示したように、主部材である固定フレーム141は、中程が45°をなして屈曲した平面視して略ヘ字形をなす。2本の固定フレーム141は、内部柱6の対角線に関して対称に、短辺141a側の端部141bが内部柱6の隅角部で連結されるため、固定フレーム141は長辺141cが平行をなす。この平行な固定フレーム141の長辺141c間を繋ぐように補剛材142、内部昇降装置120との接続部材143がボルト固定されている。また既存梁8の直上の各固定フレーム141の対応位置には、固定フレーム141を支持する束柱144が既存梁8上に立設されている。束柱144の上端は固定フレーム141に固定され、下端には高さ調整ボルト144aが取り付けられている。この高さ調整ボルト144aを用いることで固定フレーム141組付け時の長辺141cのレベル調整が容易に行える(図3(b))。一方、内部柱6の側面の所定高さには固定フレーム141の短辺141aを支持するブラケット145が取り付けられている。これにより、パーツ化された内部支持ユニット140をブラケット145に載置し、部材同士をボルト接合することにより簡単、迅速に所定位置に組み付けることができる。これら束柱144とブラケット145とにより、内部支持ユニット140は、作用する鉛直方向荷重(テルハ30の総重量、内部昇降装置120の昇降時反力等)を確実に負担する。 Here, the configuration of the internal support unit 140 will be described with reference to each of FIGS. Since the internal support unit 140 is attached to the internal columns 6 located at the four corners of the opening 7, the internal support unit 140 has a planar shape that considers the relationship between the installation position of the internal lifting device 120 and the cross-sectional shape of the internal column 6. That is, as shown in FIG. 3A, the fixed frame 141, which is the main member, has a substantially V shape when viewed in a plan view in which the fixed frame 141 is bent at a middle angle of 45°. Since the two fixed frames 141 are connected symmetrically with respect to the diagonal line of the inner column 6 at the end portions 141b on the short side 141a side at the corners of the inner column 6, the long sides 141c of the fixed frame 141 are parallel to each other. .. The stiffening member 142 and the connecting member 143 to the internal elevating device 120 are fixed by bolts so as to connect the long sides 141c of the parallel fixed frame 141. At the corresponding position of each fixed frame 141 immediately above the existing beam 8, a bundle column 144 that supports the fixed frame 141 is erected on the existing beam 8. The upper end of the bundle column 144 is fixed to the fixed frame 141, and the height adjusting bolt 144a is attached to the lower end. By using the height adjusting bolt 144a, the level of the long side 141c can be easily adjusted when the fixed frame 141 is assembled (FIG. 3B). On the other hand, a bracket 145 that supports the short side 141a of the fixed frame 141 is attached to a predetermined height on the side surface of the inner column 6. Thus, the internal support unit 140, which is made into parts, is placed on the bracket 145, and the members are bolted to each other, so that the internal support unit 140 can be easily and quickly assembled at a predetermined position. Due to the bundle columns 144 and the brackets 145, the internal support unit 140 surely bears the vertical load acting (the total weight of the Telha 30, the reaction force when the internal lifting device 120 is moved up and down, etc.).
図3を参照して上述したように、内部支持ユニット140の各部材の形状は、内部柱6の断面形状に応じて決定される。たとえば、固定フレームの短辺141aの長さは、内部柱6の一辺の長さにほぼ等しくなるため、内部柱6の断面形状が正方形であれば、2本の固定フレーム141は、平面視して対称形状(同一形状を天地反転させて対応できる)に製作される。このため、内部柱6に取り付けられた固定フレーム141は、内部柱6から開口7に向けて45°をなして突出した形状となる。さらに2本の固定フレーム141の先端間を繋いだ接続部材143に内部昇降装置120の内フレーム、外フレームがそれぞれボルト連結され、各内部昇降装置120は開口7の隅角部において、各縁辺と45°をなして配置される。言い換えると、固定フレーム141の屈曲角度は内部柱6の断面形状によって適宜設定されるため、内部柱6の断面形が正方形でない場合には、連結される2本の固定フレーム141は対称形状とならないが、固定フレーム141が開口7側に突出する角度は45°となるように、各固定フレーム141の形状(辺長)を決定することが好ましい。 As described above with reference to FIG. 3, the shape of each member of the internal support unit 140 is determined according to the cross-sectional shape of the internal column 6. For example, since the length of the short side 141a of the fixed frame is substantially equal to the length of one side of the inner column 6, if the inner column 6 has a square cross-sectional shape, the two fixed frames 141 can be seen in a plan view. It is made into a symmetrical shape (the same shape can be turned upside down to correspond). Therefore, the fixed frame 141 attached to the inner pillar 6 has a shape protruding from the inner pillar 6 by 45° toward the opening 7. Further, the inner frame and the outer frame of the internal lifting device 120 are bolted to the connecting member 143 that connects the ends of the two fixed frames 141, and each internal lifting device 120 is connected to each edge at the corner of the opening 7. It is placed at 45°. In other words, since the bending angle of the fixed frame 141 is appropriately set according to the cross-sectional shape of the inner pillar 6, the two fixed frames 141 to be connected do not have a symmetrical shape when the cross-sectional shape of the inner pillar 6 is not square. However, it is preferable to determine the shape (side length) of each fixed frame 141 so that the angle at which the fixed frame 141 projects toward the opening 7 side is 45°.
