Description

本発明は、構造物を構築する構造物構築方法、および、既存構造物を解体する構造物解体方法に関する。   The present invention relates to a structure construction method for constructing a structure and a structure disassembly method for disassembling an existing structure.

従来より、建物の新築・解体工事の工事現場では、作業エリアを覆う閉鎖型の仮設構造物が提案されている。(特許文献1参照)。   Conventionally, a closed temporary structure covering a work area has been proposed at a construction site for new construction or demolition of a building. (See Patent Document 1).

例えば、建物の新築工事では、以下のような閉鎖型の仮設構造物が提案されている(特許文献1参照)。この仮設構造物は、セルフクライミング機構を備えた複数のタワークレーンマストと、このセルフクライミング機構同士の間に架設された受梁と、この受梁の上に設けられた仮設屋根と、を備える。この仮設屋根は、屋根フレームと、この屋根フレームに張られた屋根シートと、を備える。   For example, in a new construction of a building, the following closed type temporary structure has been proposed (see Patent Document 1). The temporary structure includes a plurality of tower crane masts provided with a self-climbing mechanism, a receiving beam constructed between the self-climbing mechanisms, and a temporary roof provided on the receiving beam. The temporary roof includes a roof frame and a roof sheet stretched on the roof frame.

このような構造物によれば、作業スペースを仮設構造物で囲むので、全天候環境下で作業できるうえに、日射を抑制できるから、内部の作業環境を良好に維持できる。   According to such a structure, since the work space is surrounded by the temporary structure, it is possible to work in an all-weather environment and to suppress solar radiation, so that the internal work environment can be favorably maintained.

また、この移動仮囲い20の移動により、作業スペースSは、2階および3階に位置することになる。
In step S4, as shown in FIGS. 9 and 10, the moving temporary enclosure 20 is raised by one layer.
Specifically, the pulling member 33 is pulled out from the opening 15 at the lower level of the third floor beam, and then the hydraulic jack 72 of the lifting device 21 is driven to pull the suspension member 71 downward. Thereby, the movement temporary enclosure 20 raises. Thereafter, the yoke member 33 is inserted into the opening 15 at the lower level of the fourth floor beam.
Further, the work space S is located on the second and third floors by the movement of the movable temporary enclosure 20.

ステップS5では、ステップS3、S4を1セットとして繰り返して、移動仮囲い20を支柱11Aに沿って上昇させながら、建物1の構築作業を下階から上階に向かって行う。   In step S5, steps S3 and S4 are repeated as one set, and the construction work of the building 1 is performed from the lower floor to the upper floor while raising the moving temporary enclosure 20 along the column 11A.

本実施形態によれば、以下のような効果がある。
(1)本設床躯体30および外周足場40で作業スペースSを覆うので、全天候環境下で作業できるうえに、日射を抑制でき、内部の作業環境を良好に維持できる。また、内部で発生した騒音や粉塵が外部に漏れるのを防止できるので、周辺環境に与える影響を小さくできる。
According to this embodiment, there are the following effects.
(1) Since the work space S is covered with the main floor frame 30 and the outer periphery scaffold 40, it is possible to work in an all-weather environment, to suppress solar radiation, and to maintain a good internal work environment. Moreover, since the noise and dust generated inside can be prevented from leaking to the outside, the influence on the surrounding environment can be reduced.

また、建物1の屋上階の床躯体つまり本設床躯体30を、作業スペースSを覆う屋根とするとともに、本設の柱11を支柱11Aとして利用して、本設床躯体30を支持した。このように本設の床躯体30や柱11を用いて作業スペースSを覆ったので、仮設材を大幅に削減できるから、施工費を低減できる。   In addition, the roof frame on the roof floor of the building 1, that is, the permanent floor frame 30 was used as a roof covering the work space S, and the permanent column 11 was used as the support column 11 </ b> A to support the permanent floor frame 30. As described above, since the work space S is covered by using the main floor frame 30 and the pillars 11, temporary materials can be greatly reduced, so that the construction cost can be reduced.

Absent. For example, all the pillars 11 may be the pillars, and the positions and the number of pillars used as the pillars may be appropriately determined based on the weight of the main floor frame 30 and the outer periphery scaffold 40.

また、本実施形態では、本設床躯体30を、1層つまりR階の梁12および床スラブ13で構成したが、これに限らない。例えば、本設床躯体を、2層つまりn階およびR階の梁12および床スラブ13で構成してもよい。
また、本実施形態では、枠組足場42を、6段としたが、これに限らず、枠組足場の段数は適宜設定されてよい。
Moreover, in this embodiment, although the permanent floor frame 30 was comprised by the beam 12 and floor slab 13 of one layer, ie, the R floor, it is not restricted to this. For example, the permanent floor frame may be composed of two layers, that is, the nth and Rth floor beams 12 and the floor slab 13.
In the present embodiment, the frame scaffold 42 has six steps. However, the present invention is not limited to this, and the number of steps of the frame scaffold may be set as appropriate.

また、本実施形態では、地上にて移動仮囲い20を構築したが、これに限らず、上層階にて移動仮囲い20を構築してもよい。   Moreover, in this embodiment, although the movement temporary enclosure 20 was constructed | assembled on the ground, you may construct the movement temporary enclosure 20 not only in this but on an upper floor.

また、本実施形態では、仮設壁として外周足場40を設けたが、これに限らず、仮設壁をフレームとこのフレームに張られたネットで構成してもよいし、仮設壁を設けなくてもよい。   In the present embodiment, the outer periphery scaffold 40 is provided as a temporary wall. However, the present invention is not limited to this, and the temporary wall may be configured by a frame and a net stretched on the frame, or may not be provided with a temporary wall. Good.

また、本実施形態では、揚重設備として走行クレーン50および天井走行ホイスト60を設けたが、これらの揚重設備を必ずしも設ける必要はない。   Moreover, in this embodiment, although the traveling crane 50 and the overhead traveling hoist 60 were provided as the lifting equipment, it is not always necessary to provide these lifting equipment.

また、本実施形態では、かんぬき部材33により、移動仮囲い20を支柱11Aに仮支持させたが、これに限らない。例えば、かんぬき部材を設けず、吊り材71により、移動仮囲い20を常に吊り下げ支持してもよい。   In the present embodiment, the moving temporary enclosure 20 is temporarily supported on the support 11A by the yoke member 33, but the present invention is not limited thereto. For example, the moving temporary enclosure 20 may be always suspended and supported by the suspension member 71 without providing the yoke member.
