Description

本発明は解体方法およびこれに用いる解体補助装置に関する。   The present invention relates to a disassembly method and a disassembly assistance device used therefor.

一般的に、ビル等の高層の構造物の解体は最上階から下階へと順に行われ、解体時には、移動式クレーンやジブクレーン、天井クレーンなど、大掛かりな揚重機械を必要とする。これらの機械は、解体用の機材を屋上に搬入したり、また構造物を解体した解体材を下方へ搬出するために用いられる。   Generally, a high-rise structure such as a building is demolished in order from the top floor to the lower floor, and a large lifting machine such as a mobile crane, a jib crane, or an overhead crane is required at the time of demolition. These machines are used to carry equipment for dismantling on the rooftop or to carry down the dismantling material that dismantled the structure.

しかしながら、これらの機械を用いた従来の解体工法は、準備作業、解体作業ともに大掛かりなものになり、解体工事に時間的空間的制約が加わる要因となる。例えば狭隘な敷地では隣地との間隔も少なく、工事に必要な性能を有する大型の移動式クレーンやジブクレーンを設置することが難しい。構造物に天井クレーンを設ける場合でも、その組み立てにジブクレーンなどの設置が必要であり同様の問題が生じる。   However, the conventional dismantling method using these machines requires a large amount of preparation work and dismantling work, and is a factor that adds time and space restrictions to the dismantling work. For example, it is difficult to install a large mobile crane or jib crane that has the performance required for construction in a narrow site with little space between adjacent sites. Even when an overhead crane is provided in a structure, it is necessary to install a jib crane or the like for the assembly, and the same problem occurs.

さらに、周囲環境によっては夜間や休日に作業が限定される場合もあり、クレーンからの吊荷の落下やクレーンの転倒などの安全性の懸念もあった。   Furthermore, depending on the surrounding environment, work may be limited to nights and holidays, and there are concerns about safety such as dropping of suspended loads from the crane and falling of the crane.

これに対し、特許文献1には、上部架台および下部架台を塔状構造物に挿通するように設けて該塔状構造物に沿って昇降可能とした解体装置を用い、塔状構造物を頂部から順次解体する解体方法が記載されている。また、特許文献2には、コンクリート構造物内部の貫通溝にブロックを積層して支柱を構築し、該支柱に支持した解体作業機により最上階から解体を行い、ブロックを解体するとともに解体作業機を降下させ順次下階の解体を行う方法が示されている。   On the other hand, Patent Document 1 uses a dismantling device that is provided so that an upper frame and a lower frame are inserted through a tower-like structure and can be moved up and down along the tower-like structure. The dismantling method of dismantling sequentially is described. Further, in Patent Document 2, a block is constructed by laminating blocks in a through groove inside a concrete structure, a dismantling work machine supported by the strut is dismantled from the top floor, and the block is dismantled and the dismantling work machine The method of descending and sequentially dismantling the lower floor is shown.

特開2003−184320号公報JP 2003-184320 A 特開昭62−141262号公報Japanese Patent Laid-Open No. 62-141262

これらの解体方法は、従来の解体工事における時間的空間的制約の軽減を可能にするものである。しかしながら、一方で特許文献1の解体方法は、平面が途中でセットバックした構造物など、その平面形状によっては適用することが難しい構造物もある。また、特許文献2の解体方法では、解体装置の昇降のための支柱等の構成が大掛かりになる。   These dismantling methods make it possible to reduce temporal and spatial restrictions in conventional dismantling work. However, on the other hand, the dismantling method of Patent Document 1 is difficult to apply depending on the planar shape, such as a structure in which the plane is set back in the middle. Moreover, in the dismantling method of patent document 2, the structure of the support | pillar for the raising / lowering of a dismantling apparatus becomes large.

本発明は、上記の問題点に鑑みてなされたもので、簡易な構成で様々な構造物の解体に適用でき、解体工事の時間的空間的制約を軽減できる解体方法等を提供することを目的とする。   The present invention has been made in view of the above problems, and an object thereof is to provide a dismantling method that can be applied to dismantling of various structures with a simple configuration and can reduce the temporal and spatial constraints of dismantling work. And

前述の目的を達するための第1の発明は、構造物内部に、昇降手段を備えた解体補助装置を設ける工程と、前記解体補助装置に解体用の機材を配置し、前記解体補助装置の上方の構造物を解体しながら、前記解体補助装置を前記昇降手段により構造物の頂部まで上昇させる工程と、構造物を上から下へと順に解体するとともに、前記解体補助装置を前記昇降手段により下降させる工程と、を具備することを特徴とする解体方法である。   According to a first aspect of the present invention for achieving the above object, there is provided a step of providing a disassembly assisting device provided with lifting means inside a structure, disposing dismantling equipment in the disassembly assisting device, and above the disassembly assisting device While dismantling the structure, the step of lifting the disassembly assisting device to the top of the structure by the lifting means, and disassembling the structure from top to bottom in order, and lowering the disassembly assisting device by the lifting means And a disassembling method comprising the steps of:

本発明では、解体作業がほぼ構造物の内部で完結できるので、時間的空間的制約を軽減できる。さらに、本発明の解体方法は、構造物の平面がセットバックしている場合なども含め、任意の形状の構造物に適用することができる。加えて、解体補助装置の昇降のため支柱等を設ける必要もなく、簡易に解体作業を行うことができる。さらに、解体作業中には、解体補助装置が、該解体補助装置の上昇時に形成された開口を塞いだ状態であるので、作業員や工具の落下を防ぐことができる利点もある。また、解体補助装置は構造物の下部で組み立てることができるので安全性も高い。   In the present invention, since the dismantling work can be almost completed inside the structure, the temporal and spatial constraints can be reduced. Furthermore, the disassembling method of the present invention can be applied to a structure having an arbitrary shape including the case where the plane of the structure is set back. In addition, it is not necessary to provide a column or the like for raising and lowering the disassembly assisting device, and the disassembly work can be easily performed. Further, during the dismantling operation, the disassembly assisting device is in a state of closing the opening formed when the disassembling assisting device is lifted, so that there is an advantage that it is possible to prevent a worker or a tool from dropping. Moreover, since the disassembly assistance device can be assembled at the lower part of the structure, safety is high.

前記解体補助装置には、解体用の機材および構造物を解体した解体材を搬送するためのリフトが備えられていることが望ましい。
このように、解体補助装置にリフトを設けることで、新たな機材の搬入、機材の搬送、および解体材の搬出などが容易に行える。また、構造物の内部でリフトを昇降してこれらを搬送できるので、外部に落下する恐れも無い。さらに、解体補助装置を昇降するだけで、リフト自体を移設したのと同様の効果が得られる利点もある。
The disassembly assisting device is preferably provided with a lift for transporting the dismantling material obtained by disassembling the dismantling equipment and structure.
Thus, by providing a lift to the disassembly assisting device, it is possible to easily carry in new equipment, transport equipment, and carry out dismantling material. Moreover, since these can be conveyed by raising / lowering a lift inside a structure, there is no possibility of falling outside. Furthermore, there is also an advantage that the same effect as that obtained by moving the lift itself can be obtained simply by raising and lowering the disassembly assisting device.

前記解体補助装置を構造物の頂部まで上昇させた後、構造物の外周部から前記解体補助装置へと屋根を架け渡すことが望ましい。
これにより、解体に伴う粉塵等の飛散や騒音を抑制できる。また、解体補助装置を用いて屋根を架け渡すので、屋根を支持する間隔が狭くなり、大きな屋根フレーム等が不要となるなど、屋根の構成を簡易とできる。
After raising the disassembly assisting device to the top of the structure, it is desirable to bridge the roof from the outer periphery of the structure to the disassembly assisting device.
Thereby, scattering of dust etc. and noise accompanying dismantling can be suppressed. Further, since the roof is bridged by using the disassembly assisting device, the roof configuration can be simplified such that the interval for supporting the roof is narrowed and a large roof frame or the like is not required.

前記解体補助装置は複数配置され、前記解体補助装置を構造物の頂部まで上昇させた後、複数の前記解体補助装置を連結することが望ましい。
これにより、解体補助装置の平面寸法を拡張して剛強な構造とでき、解体作業中に解体補助装置に加わる荷重を広面積に分散させ、解体補助装置から構造物へ加わるモーメントを低減できる。
It is desirable that a plurality of the disassembly assistance devices are arranged, and the plurality of the disassembly assistance devices are connected after raising the disassembly assistance device to the top of the structure.
Accordingly, the planar dimension of the disassembly assisting device can be expanded to have a rigid structure, and the load applied to the disassembly assisting device during the dismantling operation can be dispersed over a wide area, and the moment applied from the disassembly assisting device to the structure can be reduced.

前記解体補助装置は複数配置され、前記解体補助装置には、解体用の機材および構造物を解体した解体材を搬送するためのリフトが備えられ、前記複数の解体補助装置のリフトをつるべ式に接続しリフトによる搬送を行うことが望ましい。
このように、各解体補助装置に備えたリフト同士を繋いでつるべ式にすることで、リフト昇降に係る動力を抑制できる。
A plurality of the disassembly assisting devices are arranged, and the disassembly assisting device is provided with a lift for transporting the dismantling material dismantling the dismantling equipment and structure, and the lifts of the plurality of disassembly assisting devices are in a sliding manner. It is desirable to connect and carry by lift.
Thus, the motive power which concerns on lift raising / lowering can be suppressed by connecting the lifts with which each disassembly assistance apparatus was made, and making it a slab type.

前記解体補助装置に、解体用のクレーンが取り付けられることが望ましい。
これにより、解体作業をスピードアップさせることができる。
It is desirable that a crane for disassembly is attached to the disassembly assisting device.
This can speed up the dismantling work.

前記解体補助装置に、構造物の外側に配置された足場が接続されることが望ましい。
構造物の外側に足場を設けることで、構造物の外側からの作業が省スペースで可能になり、また、昇降式の解体補助装置と足場を接続するので、足場の移設も容易にできる。
It is desirable that a scaffold disposed outside the structure is connected to the disassembly assistance device.
By providing a scaffold outside the structure, it is possible to work from the outside of the structure in a space-saving manner, and the lifting / disassembling auxiliary device and the scaffold are connected, so that the scaffold can be easily moved.

第2の発明は、解体する構造物の内部に配置し、構造物の解体に用いる解体補助装置であって、本体フレームに、解体補助装置を昇降させるための昇降手段と、解体用の機材および構造物を解体した解体材を搬送するためのリフトと、を取り付けたことを特徴とする解体補助装置である。   A second invention is a disassembly assisting device that is disposed inside a structure to be dismantled and used for dismantling the structure, and is provided with lifting means for lifting and lowering the disassembly assisting device on the main body frame, dismantling equipment, and A disassembly assisting device comprising a lift for transporting a dismantling material dismantling a structure.

また、解体補助装置には、解体用のクレーンが取り付けられることが望ましい。
さらに、構造物の外側に配置された足場が取り付けられることも望ましい。
Moreover, it is desirable that a dismantling crane is attached to the dismantling auxiliary device.
Furthermore, it is also desirable that a scaffold placed outside the structure is attached.

本発明により、簡易な構成で様々な構造物の解体に適用でき、解体工事の時間的空間的制約を軽減できる解体方法等を提供することができる。   According to the present invention, it is possible to provide a dismantling method that can be applied to dismantling of various structures with a simple configuration and can reduce the temporal and spatial restrictions of dismantling work.

図2は解体補助装置10を示す図である。図2(a)は解体補助装置10の立面を示す図、図2(b)は解体補助装置10の上面を示す図である。図に示すように、この解体補助装置10は、本体フレーム11に、リフト12およびアウトリガー13を設けたものである。   FIG. 2 is a view showing the disassembly assisting device 10. FIG. 2A is a diagram illustrating an elevation surface of the disassembly assisting device 10, and FIG. 2B is a diagram illustrating an upper surface of the disassembly assisting device 10. As shown in the figure, the disassembly assisting device 10 has a main body frame 11 provided with a lift 12 and an outrigger 13.

本体フレーム11は鋼材等により立体格子状に形成される。本体フレーム11上には天板が設けられ、その上で解体用の機材の配置、および移動が可能である。また、本体フレーム11の下部には鉛直方向に伸縮可能な伸縮柱11aが設けられている。   The main body frame 11 is formed in a three-dimensional lattice shape with a steel material or the like. A top plate is provided on the main body frame 11, on which disposition equipment can be arranged and moved. In addition, a telescopic column 11 a that can extend and contract in the vertical direction is provided at a lower portion of the main body frame 11.

The outrigger 13 can be moved back and forth with respect to the end portion of the beam member 11b. In the present embodiment, the telescopic column 11 a and the outrigger 13 constitute an elevating unit for elevating the disassembly assisting device 10.

(解体補助装置10を用いた構造物1の解体方法)
本実施形態では、この解体補助装置10を利用して構造物1を解体する。この解体方法を図3〜図9を参照して以下説明する。
(Disassembly method of the structure 1 using the disassembly assistance apparatus 10)
In the present embodiment, the structure 1 is disassembled using the disassembly assisting device 10. This dismantling method will be described below with reference to FIGS.

(1.解体補助装置10の構築)
図3は構造物1における解体補助装置10の構築を示す図である。図3(a)は構造物1の垂直方向の断面を示す図、図3(b)は図3(a)の線B−Bによる水平方向の断面を示す図である。
(1. Construction of disassembly assistance device 10)
FIG. 3 is a diagram illustrating the construction of the disassembly assistance device 10 in the structure 1. 3A is a diagram showing a cross section in the vertical direction of the structure 1, and FIG. 3B is a diagram showing a cross section in the horizontal direction along the line BB in FIG. 3A.

図に示すように、本実施形態では、まず、グラウンドレベルで前記の本体フレーム11、リフト12、アウトリガー13等を組み立てて、2基の解体補助装置10を構造物1内部の隣り合う区画で構築する。なお、解体補助装置10の構築のためのスペースは、構造物1の一部を解体するなどして確保する。
また、解体補助装置10の上に、スラブ5や梁9を解体するためのスラブ・梁解体ロボット21を配置する。
As shown in the figure, in the present embodiment, first, the main body frame 11, the lift 12, the outrigger 13 and the like are assembled at the ground level, and the two disassembly assisting devices 10 are constructed in adjacent sections inside the structure 1. To do. In addition, the space for construction of the disassembly assistance apparatus 10 is ensured by disassembling a part of the structure 1 or the like.
Further, a slab / beam disassembly robot 21 for disassembling the slab 5 and the beam 9 is disposed on the disassembly assisting device 10.

なお、2基の解体補助装置10のリフト12については、リフト12の下降時にモーター制御等で生じる回生電流を蓄電等し、該リフト12、あるいは他のリフト12の稼働に使用するようにしてもよい。これにより、リフト12の昇降にかかる動力を低減できる。
あるいは、これらのリフト12はワイヤ等でつるべ式に接続してもよい。すなわち、一方のリフト12が上昇すると、他方のリフト12が下降するように接続することもできる。これによっても、リフト12の昇降にかかる動力を低減できる。
For the lifts 12 of the two disassembly assistance devices 10, the regenerative current generated by motor control or the like when the lift 12 is lowered is stored and used for the operation of the lift 12 or other lifts 12. Good. Thereby, the power concerning the raising / lowering of the lift 12 can be reduced.
Alternatively, these lifts 12 may be connected in a sliding manner with wires or the like. That is, it can be connected such that when one lift 12 is raised, the other lift 12 is lowered. This can also reduce the power required to raise and lower the lift 12.

一方、構造物1の外側では、支柱31を構造物1に接続しつつ上方へと組み上げるとともに、該支柱31に昇降式の外部養生足場30を取り付ける。この外部養生足場30は、支柱31に沿って昇降可能である。   On the other hand, outside the structure 1, the support 31 is assembled upward while being connected to the structure 1, and an elevating external curing scaffold 30 is attached to the support 31. The external curing scaffold 30 can be moved up and down along the column 31.

(2.解体補助装置10の上昇)
続いて、スラブ・梁解体ロボット21で上方のスラブ5等を解体しながら、図4に示すように、解体補助装置10を上昇させてゆく。解体材は、リフト12を用いて下方に搬出する。なお、本実施形態では、2基の解体補助装置10を配置した隣り合う区画の間の梁9は解体せずに残しておき後の工程で解体する。これにより、解体の手間をかけずに解体補助装置10を上昇させることができる。ただし、この梁9は解体補助装置10を上昇させる際に解体してもよい。
(2. Ascent of disassembly assisting device 10)
Subsequently, while disassembling the upper slab 5 and the like with the slab / beam dismantling robot 21, the disassembly assisting device 10 is raised as shown in FIG. The dismantling material is carried out downward using the lift 12. In this embodiment, the beam 9 between adjacent sections where the two disassembly assisting devices 10 are arranged is left without being disassembled and disassembled in a later process. Thereby, the disassembly assistance apparatus 10 can be raised without taking the effort of disassembly. However, the beam 9 may be disassembled when the disassembly assisting device 10 is raised.

図5(a)〜(d)は解体補助装置10の上昇について示す図である。図5(a)〜(d)において、上図は解体補助装置10の立面を示し、下図はアウトリガー13の進退について示す。   FIGS. 5A to 5D are diagrams illustrating the lifting of the disassembly assisting device 10. 5A to 5D, the upper diagram shows the elevation of the disassembly assisting device 10, and the lower diagram shows the advance and retreat of the outrigger 13.

図5(a)に示すように、解体補助装置10は、アウトリガー13を桁材11bから出して構造物1の梁9上に載置して固定することで、梁9上で支持される。そして、上方のスラブ5等の解体を行いながら、図5(b)に示すように、解体補助装置10の伸縮柱11aを伸長させる。   As shown in FIG. 5A, the disassembly assisting device 10 is supported on the beam 9 by taking out the outrigger 13 from the beam 11b and placing it on the beam 9 of the structure 1 and fixing it. Then, while disassembling the upper slab 5 and the like, as shown in FIG. 5B, the telescopic column 11a of the disassembly assisting device 10 is extended.

その後、本体フレーム11を固定手段(不図示)で構造物1に固定し、図5(c)に示すように、アウトリガー13の固定を外して桁材11b内部に引込める。そして、前記の伸縮柱11aを収縮させて桁材11bを上階の梁9の位置まで引き上げる。その後、アウトリガー13を桁材11bから出して上階の梁9上に載置して固定し、上階の梁9上で解体補助装置10を支持する。   Thereafter, the main body frame 11 is fixed to the structure 1 by a fixing means (not shown), and the outrigger 13 is unfixed and retracted into the beam member 11b as shown in FIG. 5 (c). Then, the telescopic column 11a is contracted to raise the beam member 11b to the position of the beam 9 on the upper floor. Thereafter, the outrigger 13 is removed from the beam member 11b and placed on the beam 9 on the upper floor and fixed, and the disassembly assisting device 10 is supported on the beam 9 on the upper floor.

そして、本体フレーム11の固定を解除し、上方のスラブ5等の解体を行いながら、図5(d)に示すように伸縮柱11aを伸長させる。解体補助装置10は、以上の作業を繰り返しながら上方へ移動させる。   Then, the main frame 11 is released and the telescopic column 11a is extended as shown in FIG. 5 (d) while disassembling the upper slab 5 and the like. The disassembly assistance device 10 is moved upward while repeating the above operations.

ただし、解体補助装置10を昇降させる方法はこれに限ることはない。例えば、アウトリガー13を用いる代わりに、特開2005−272116号公報に示されているように、構造物1内部に解体補助装置10を支持するための仮設のブラケットを取け付けてもよい。すなわち、構造物1の下階に取り付けた仮設のブラケットで解体補助装置10を支持しつつ、前記と同様に伸縮柱11aの伸縮等を行い、その後、構造物1の上階に仮設のブラケットを取り付けてこれにより解体補助装置10を支持させる。これを繰り返すことで、解体補助装置10を上昇させることもできる。   However, the method of raising / lowering the disassembly assistance apparatus 10 is not restricted to this. For example, instead of using the outrigger 13, a temporary bracket for supporting the disassembly assisting device 10 may be attached to the inside of the structure 1 as disclosed in JP-A-2005-272116. That is, while supporting the disassembly assisting device 10 with a temporary bracket attached to the lower floor of the structure 1, the telescopic column 11a is expanded and contracted in the same manner as described above, and then the temporary bracket is mounted on the upper floor of the structure 1. It attaches and this supports the disassembly assistance apparatus 10. By repeating this, the disassembly assisting device 10 can be raised.

一方、構造物1の外側では支柱31を引き続き上方へと組み上げ、該支柱31に沿って外部養生足場30をクライミングさせる。このようにして、図6に示すように、解体補助装置10と外部養生足場30を構造物1の頂部まで移動させる。   On the other hand, on the outside of the structure 1, the support 31 is continuously assembled upward, and the external curing scaffold 30 is climbed along the support 31. In this way, the disassembly assistance device 10 and the external curing scaffold 30 are moved to the top of the structure 1 as shown in FIG.

(3.構造物1の解体)
解体補助装置10を頂部まで移動させると、図7に示すように、解体補助装置10の本体フレーム11同士を連結部14で連結する。さらに、図8に示すように、構造物1の外周部から解体補助装置10の頂部へと屋根40を架け渡し、構造物1の頂部を屋根40で覆う。屋根40は、シートをワイヤにより支持した簡易なもので、蛇腹状に折り畳んだものを引き延ばしつつ架け渡すことができる。
(3. Dismantling of structure 1)
When the disassembly assisting device 10 is moved to the top, the main body frames 11 of the disassembly assisting device 10 are connected by the connecting portion 14 as shown in FIG. Furthermore, as shown in FIG. 8, the roof 40 is bridged from the outer periphery of the structure 1 to the top of the disassembly assisting device 10, and the top of the structure 1 is covered with the roof 40. The roof 40 is a simple one in which a sheet is supported by a wire, and the roof 40 can be stretched over while being stretched in a bellows shape.

また、必要に応じて、前記のスラブ・梁解体ロボット21に加え、解体に必要なユニット型の支保工や柱3を解体するための柱解体ロボット22、あるいは別のスラブ・梁解体ロボット21など、解体用の機材をリフト12を用いて新たに搬入する。
そして、これらを用いてスラブ5、梁9、柱3の順に構造物1を解体する。解体材はリフト12を用いて下方へと搬出する。構造物1の1フロアを解体するごとに、リフト12により解体用の機材等を下階へ搬送し、図5と逆の手順により解体補助装置10を下階へと降ろす。
If necessary, in addition to the slab / beam demolition robot 21, a unit-type support work necessary for demolition, a column demolition robot 22 for demolition of the column 3, or another slab / beam demolition robot 21 Then, new equipment for dismantling is carried in using the lift 12.
And the structure 1 is demolished in order of the slab 5, the beam 9, and the pillar 3 using these. The demolished material is carried out downward using the lift 12. Each time one floor of the structure 1 is dismantled, the dismantling equipment and the like are transported to the lower floor by the lift 12, and the disassembly assisting device 10 is lowered to the lower floor by the reverse procedure of FIG.

一方、構造物1の外側では、これと並行して、外部養生足場30を用いて、カーテンウォール7の解体と、解体材の下方への搬出を行う。カーテンウォール7の解体は頂部から行い、これに伴い不要となった支柱31の上部はカーテンウォール7と同じく解体し撤去する。   On the other hand, on the outside of the structure 1, in parallel with this, the external curing scaffold 30 is used to disassemble the curtain wall 7 and carry out the dismantling material downward. The curtain wall 7 is disassembled from the top, and the upper portion of the column 31 that is no longer necessary is disassembled and removed in the same manner as the curtain wall 7.

こうして、図9に示すように構造物1を頂部から下方へと順に解体してゆき、グラウンドレベルまで構造物1の解体を行う。   Thus, as shown in FIG. 9, the structure 1 is disassembled sequentially from the top to the bottom, and the structure 1 is disassembled to the ground level.

なお、本実施形態では、解体用の機材として、スラブ・梁解体ロボット21や柱解体ロボット22等を用いているが、これに限ることはない。例えば、図4で説明したように解体補助装置10の上昇時に上方のスラブ5等を解体したり、図8等で説明したように構造物1を頂部から解体する際に、解体用の機材として破砕機などを用いることも可能である。   In this embodiment, the slab / beam dismantling robot 21 and the pillar dismantling robot 22 are used as dismantling equipment, but the present invention is not limited to this. For example, when disassembling the upper slab 5 or the like when the disassembly assisting device 10 is lifted as described in FIG. 4 or when disassembling the structure 1 from the top as described in FIG. It is also possible to use a crusher or the like.

以上説明したように、本実施形態では、解体補助装置10を上記のように使用することで、解体用の機材や解体材を搬送するための大型の移動式クレーンやジブクレーン等が不要になり、解体作業がほぼ構造物1の内部で完結できるので、解体工事の時間的空間的制約を軽減できる。   As described above, in the present embodiment, by using the disassembly assisting device 10 as described above, a large mobile crane, a jib crane, or the like for transporting dismantling equipment or dismantling material becomes unnecessary. Since the dismantling work can be almost completed inside the structure 1, the temporal and spatial restrictions of the dismantling work can be reduced.

また、構造物1の平面がセットバックしたり、構造物1の形状が傾斜している場合では、屋上に大型の天井クレーンを設けたり、前記の特許文献1に記載の解体方法を適用することが困難であるが、本実施形態はこのような場合をはじめ、任意の構造物形状に適用できる。さらに、特許文献2の解体方法のように、解体補助装置10の昇降のために支柱等を組み立てる必要もなく、簡易に解体作業を行うことができる。さらに、解体作業中には、解体補助装置10が、該解体補助装置10の上昇時に形成された開口を塞いだ状態であるので、作業員や工具の落下を防ぐことができる利点もある。さらに、解体補助装置10は構造物1の下部で組み立てるので安全性も高い。   Moreover, when the plane of the structure 1 is set back or the shape of the structure 1 is inclined, a large overhead crane is provided on the roof, or the dismantling method described in Patent Document 1 is applied. However, the present embodiment can be applied to any structure shape including such a case. Furthermore, unlike the disassembly method of Patent Document 2, it is not necessary to assemble a column or the like for raising and lowering the disassembly assistance device 10, and disassembly work can be performed easily. Further, during the dismantling operation, the disassembly assisting device 10 is in a state of closing the opening formed when the disassembling assisting device 10 is lifted, so that there is an advantage that it is possible to prevent a worker or a tool from dropping. Furthermore, since the disassembly assistance apparatus 10 is assembled at the lower part of the structure 1, the safety is high.

また、解体補助装置10にリフト12を設けているので、新たな機材の搬入、機材の搬送、および解体材の搬出などを容易に行うことができ、大型のクレーン等が不要である。また、構造物1の内部でリフト12を昇降してこれらを搬送できるので、外部に落下する恐れも無い。また、解体補助装置10を昇降するだけで、リフト12自体を移設したのと同様の効果が得られる利点もある。   Further, since the disassembly assisting device 10 is provided with the lift 12, it is possible to easily carry in new equipment, transport equipment, and carry out dismantling material, and a large crane or the like is unnecessary. In addition, since the lift 12 can be lifted and lowered inside the structure 1, there is no possibility of dropping to the outside. Moreover, there exists an advantage by which the same effect as having moved the lift 12 itself is acquired only by raising / lowering the disassembly assistance apparatus 10. FIG.

さらに、構造物1の外周部から解体補助装置10へと屋根40を架け渡すので、解体に伴う粉塵等の飛散や騒音を抑制できる。また、解体補助装置10を用いて屋根40を架け渡すので、屋根40を支持する間隔が狭くなり、大きな屋根フレーム等が不要となるなど、屋根40の構成を簡易とできる。   Furthermore, since the roof 40 is bridged from the outer periphery of the structure 1 to the disassembly assisting device 10, scattering of dust and the like and noise accompanying disassembly can be suppressed. Moreover, since the roof 40 is bridged using the disassembly assistance apparatus 10, the space | interval which supports the roof 40 becomes narrow, a big roof frame etc. become unnecessary, and the structure of the roof 40 can be simplified.

また、本実施形態では、2基の解体補助装置10を並べて配置し、これらの解体補助装置10を構造物1の頂部まで上昇させた後連結するので、平面寸法を拡張して剛強な構造とでき、解体作業中に解体補助装置10に加わる荷重を広面積に分散させ、解体補助装置10から構造物1へ加わるモーメントを低減できる。   Further, in this embodiment, two disassembly assistance devices 10 are arranged side by side, and these disassembly assistance devices 10 are connected to the top of the structure 1 and then connected to each other. The load applied to the disassembly assisting device 10 during the dismantling operation can be dispersed over a wide area, and the moment applied to the structure 1 from the disassembly assisting device 10 can be reduced.

なお、本実施形態では2基の解体補助装置10をそれぞれ上昇させた後、最上階で連結しているが、予め地上で2基の解体補助装置10を連結した後、これらを同時に上昇させてもよい。
また、解体補助装置10の配置も適宜定めることができ、例えば構造物1内で離れた複数の位置に設けてもよく、あるいは構造物1内で1基のみ設けてもよい。加えて、本体フレーム11の大きさや形状等も適宜定めることができる。
In this embodiment, the two disassembly assisting devices 10 are respectively raised and then connected on the top floor. However, after the two disassembly assisting devices 10 are connected in advance on the ground, they are simultaneously raised. Also good.
Further, the disposition assisting device 10 can be arranged as appropriate. For example, the disassembly assisting device 10 may be provided at a plurality of positions separated from each other in the structure 1, or only one unit may be provided in the structure 1. In addition, the size and shape of the main body frame 11 can be determined as appropriate.

さらに、本実施形態ではグラウンドレベルで解体補助装置10を構築したが、構造物1の途中階で解体補助装置10を構築し、そこから解体補助装置10を上昇させることもできる。   Further, in the present embodiment, the disassembly assisting device 10 is constructed at the ground level, but the disassembly assisting device 10 can be constructed on the intermediate floor of the structure 1 and the disassembly assisting device 10 can be raised therefrom.

この他、解体補助装置10の本体フレーム11には、解体に用いる小型のウォールクレーンを取り付けることも可能である。図10に、解体補助装置10にウォールクレーン51を取り付けた例を示す。図10(a)は構造物1の垂直方向の断面を示す図である。図10(b)は解体補助装置10を上から見た図であり、点線は1台のウォールクレーン51の可動範囲を示す。また、図10(c)、図10(d)はウォールクレーン51のブーム51aの例を示す。   In addition, a small wall crane used for disassembly can be attached to the main body frame 11 of the disassembly assisting device 10. In FIG. 10, the example which attached the wall crane 51 to the disassembly assistance apparatus 10 is shown. FIG. 10A is a view showing a cross section of the structure 1 in the vertical direction. FIG. 10B is a view of the disassembly assisting device 10 as viewed from above, and the dotted line indicates the movable range of one wall crane 51. 10C and 10D show examples of the boom 51a of the wall crane 51. FIG.

ウォールクレーン51は、例えば、解体補助装置10を構造物1の頂部まで上昇させた後、リフト12により構成部材を地上から引き揚げ、これを組み立てて構築することができる。このウォールクレーン51は、ジブクレーンよりも小型かつシンプルな構成とし、多く設置できるので解体スピードを上げることができる。また、小さな作業半径の機械で済むので組立が容易である。さらに、解体補助装置10を昇降させることで、ウォールクレーン51等の設備が一度に移設できる利点もある。
また、ウォールクレーン51の場合、図10(c)に示すようにブーム51aを多段式としてスライド可能にしたり、あるいは図10(d)に示すようにブーム51aを折り畳み式にして端部を回転可能にすることで、ブーム51aを旋回しても構造物1の平面内から出ることなく、かつ構造物1の隅までクレーンを届かせることができる。
The wall crane 51 can be constructed by, for example, raising the disassembly assisting device 10 to the top of the structure 1 and then lifting the components from the ground by the lift 12 and assembling them. The wall crane 51 is smaller and simpler than a jib crane and can be installed in a large number, so that the disassembly speed can be increased. Further, since a machine with a small working radius is sufficient, assembly is easy. Furthermore, there is also an advantage that equipment such as the wall crane 51 can be moved at a time by raising and lowering the disassembly assisting device 10.
In the case of the wall crane 51, the boom 51a can be slid as a multi-stage as shown in FIG. 10C, or the end of the boom 51a can be foldable as shown in FIG. 10D. By doing so, the crane can reach the corner of the structure 1 without coming out of the plane of the structure 1 even if the boom 51a is turned.

また、本実施形態では、構造物1の外側に外部養生足場30を解体補助装置10と別に設けたが、構造物の外側の足場と解体補助装置10を接続してもよい。図11はこれを示す図であり、図11(a)は構造物1aの垂直方向の断面を示す図、図11(b)は図11(a)の線C−Cによる水平方向の断面を示す図である。   Further, in this embodiment, the external curing scaffold 30 is provided outside the structure 1 separately from the disassembly assisting device 10, but the scaffold outside the structure and the disassembly assisting device 10 may be connected. FIG. 11 is a view showing this, FIG. 11A is a view showing a vertical section of the structure 1a, and FIG. 11B is a horizontal section taken along line CC in FIG. 11A. FIG.

図11に示すように、この例では、構造物1aの外周部に沿って複数の解体補助装置10を設けるとともに、各解体補助装置10と、構造物1の外側に配置した外部養生足場30aとを接続している。この場合、構造物1の外部からの作業が容易になるとともに、外部養生足場30aが解体補助装置10の昇降とともに移設できるようになり手間がかからない。   As shown in FIG. 11, in this example, a plurality of disassembly assistance devices 10 are provided along the outer periphery of the structure 1 a, and each disassembly assistance device 10 and an external curing scaffold 30 a disposed outside the structure 1 are provided. Is connected. In this case, the work from the outside of the structure 1 is facilitated, and the external curing scaffold 30a can be moved along with the lifting and lowering of the disassembly assisting device 10, so that it does not take time.
