Description

本発明は、建築構造物を取り囲んだ状態に組上げられる足場等の仮設構造物の組上げ方法に関するものである。   The present invention relates to a method for assembling a temporary structure such as a scaffold that is assembled in a state of surrounding a building structure.

この種の作業台として、枠組足場が知られている。一般に、枠組足場は、軸組となる複数の建枠と、作業床となる複数の布枠と、補強部材となるブレース等とにより主要部を構成している。
建枠は、２本の建地とこの建地の上端部間に設置された横地とから略門形（鳥居形）状に形成されたユニット材で、工事中の建築構造物の各面に所定間隔おきに建て付けられ、且つ、上下を差し込む等して複数段に組み上げられている。また、布枠は各段の建枠の横地間に架け渡されている。 A frame scaffold is known as this type of workbench. In general, a frame scaffolding includes a plurality of building frames as a shaft, a plurality of fabric frames as work floors, and braces as reinforcement members.
The building frame is a unit material formed in the shape of a gate (torii-shaped) from two buildings and a horizontal land installed between the upper ends of this building, on each side of the building structure under construction It is built at predetermined intervals and is assembled in multiple stages by inserting the top and bottom. Moreover, the cloth frame is spanned between the horizontal grounds of the building frame of each step.

枠組足場の組立てに際しては、建枠と布枠を一段一段上に順に組み上げ、解体に際しては一段一段上から下へ順に建枠と布枠を解体して撤去する（例えば特許文献１参照）。
特開２００３−１２００１８号公報 When assembling the frame scaffolding, the building frame and the cloth frame are assembled one by one in order, and when disassembling, the building frame and the cloth frame are disassembled in order from the top to the bottom one by one (see Patent Document 1, for example).
JP 2003-120018 A

しかしながら、上記枠組み足場の組立てにおいては、建築構造物の各面に対して順次建枠と布枠を組み上げていくこととなり、手間がかかるばかりでなく、各面の前方に広い作業スペースを必要とする問題があった。また、作業者の行き来の盛んな地上においても建築構造物の手前に足場が構築されているため、該足場を介さなければ建築構造物にアクセスすることができず、足場の存在により地上での作業を効率よく行うことが却って困難となってしまう問題もある。
そこで、本発明は、狭小なスペースにおいて組み上げることができ、且つ組上げ後も地上での建築構造物へのアクセスを容易なものとする仮設構造物の組上げ方法を提供するようにしたものである。 However, in assembling the above-mentioned framework scaffold, the building frame and the cloth frame are sequentially assembled on each side of the building structure, which is troublesome and requires a large work space in front of each side. There was a problem to do. In addition, since the scaffolding is built in front of the building structure even on the ground where workers come and go, the building structure cannot be accessed without the scaffolding. There is also a problem that it is difficult to perform the work efficiently.
Therefore, the present invention provides a method for assembling a temporary structure that can be assembled in a narrow space and that allows easy access to the building structure on the ground even after the assembly.

前記目的を達成するため、本発明においては以下の技術的手段を講じた。
即ち、本発明における課題解決のための技術的手段は、仮設構造物の組上げ方法において、建築構造物の周囲に根柱を点在させた状態で設置し、
隣り合う根柱どうしを根太材で連結して前記建築構造物の下端部を包囲する下基枠を形成し、
各根柱上に支柱をそれぞれ立設し、
各支柱の上端部を屋根フレームで連結して前記建築構造物全体を取り囲む中間構造体を形成した後、
前記根太材を取り外すことを特徴としている。 In order to achieve the above object, the present invention takes the following technical means.
That is, the technical means for solving the problems in the present invention is a method for assembling a temporary structure, in a state where the root pillars are scattered around the building structure,
Adjacent root pillars are connected with joist to form a lower base frame surrounding the lower end of the building structure,
Each column is erected on each root pillar,
After forming the intermediate structure surrounding the entire building structure by connecting the upper end of each column with a roof frame,
The joist is removed.

これによれば、先ず、建築構造物の下端部を取り囲んで下基枠が形成され、該下基枠上に支柱が立設されるので、各支柱が下基枠を介して連結されることとなる。したがって、下基枠と各支柱とからなる構造体が形成されることとなり、各支柱に対する支持強度を向上させることができる。そして、該構造体の支柱の上端部に屋根フレームが連結されて中間構造体が形成された後、下基枠を構成する根太材を取り外すと、支柱を屋根フレームにより連結してなる構造体が成立することとなり、これによって、各支柱及び屋根フレームは当該構造体として一体となって外力に抗するものとなるのである。   According to this, first, the lower base frame is formed surrounding the lower end portion of the building structure, and the columns are erected on the lower frame, so that the columns are connected via the lower frame. It becomes. Therefore, a structure composed of the lower base frame and each column is formed, and the support strength for each column can be improved. Then, after the roof frame is connected to the upper end of the pillar of the structure to form the intermediate structure, the structure formed by connecting the pillar with the roof frame when the joist material constituting the lower base frame is removed. As a result, the respective struts and the roof frame are integrated as a structure to resist external forces.

したがって、本発明に係る仮設構造物の組上げ方法によれば、支柱の組上げから仮設構造物の組上げ完了に至るまで、また、組上げが完成した後も、一定の強度を有する構造体として成立することとなり、各部材が該構造体として一体となって外力に抵抗することとなるので、仮設構造物としての強度を一定に維持することができるものとなる。
そして、根太材が根柱間から取り外されることにより、地上での建築構造物とその周囲の間の往復の際に障害がなくなり、作業者は地上にて容易に建築構造物とその周囲の間を往復することができるものとなるのである。 Therefore, according to the method for assembling the temporary structure according to the present invention, the structure having a certain strength is established from the assembling of the support column to the completion of the assembling of the temporary structure and after the assembling is completed. Thus, each member is integrated with the structure and resists external force, so that the strength of the temporary structure can be maintained constant.
The joist is removed from between the pillars so that there is no obstacle in the round trip between the building structure on the ground and the surrounding area, and the operator can easily connect the building structure and the surrounding area on the ground. It is possible to reciprocate.

また、上記仮設構造物においては、建築構造物の周囲に複数の根柱を設置するスペースがあれば組み上げることができ、組上げのための作業スペースの狭小化を図ることができる。また、構成する部材も少なく、組上げに広大な作業領域を要することはない。
また、前記屋根フレームは、前記建築構造物の屋根面の流れ方向に向けて延びる梁材と、該屋根面の流れ方向とは垂直となる方向に延びる桁材とを備え、前記建築構造物を介して対向する前記支柱を梁材により連結した後、前記建築構造物に沿って隣り合う前記支柱の上端部を桁材により連結することが好ましい。 Further, the temporary structure can be assembled if there is a space for installing a plurality of root pillars around the building structure, and the work space for the assembly can be reduced. In addition, since the number of members is small, a large work area is not required for assembly.
The roof frame includes a beam member extending in a flow direction of the roof surface of the building structure, and a girder extending in a direction perpendicular to the flow direction of the roof surface. It is preferable to connect the upper ends of the struts adjacent to each other along the building structure with a beam after connecting the struts facing each other with a beam member.

また、前記根柱に取り付けられる支柱を、長尺に形成された柱部材の一端部に前記屋根フレームに連結可能な連結部材を設けることにより形成しておくことが好ましい。これにより、容易に支柱に屋根フレームを連結することができるものとなる。   Moreover, it is preferable to form the support | pillar attached to the said root pillar by providing the connection member which can be connected with the said roof frame in the end part of the column member formed in elongate. Thereby, a roof frame can be easily connected to a support | pillar.

本発明の仮設構造物の組上げ方法によれば、狭小なスペースにおいて組み上げることができ、且つ組上げ後も地上での建築構造物へのアクセスを容易なものとなる。   According to the method for assembling a temporary structure of the present invention, it is possible to assemble in a small space, and it is easy to access the building structure on the ground even after assembling.

Thereby, the intermediate structure 60 which forms the very stable structure which connects the lower end part of the frame structure which consists of the support | pillar 12 and the roof frame 13 by a base frame in each elevation surface will be formed.
Thereafter, as shown in FIGS. 10A to 10C, each joist member 61 of the lower base frame 62 is removed, and thereby the assembly of the temporary structure 1 surrounding the building structure A is completed.

なお、図１に示す如く、屋根フレーム１３の各梁材４０及び桁材４１に亘ってシート等の屋根面構成部材７０を被せることにより屋根面を構成することも可能である。これにより、建築構造物Ａへの降水や日射を防ぐことができるものとなる。
本実施の形態によれば、先ず、建築構造物Ａの下端部を取り囲んで下基枠６２が形成され、該下基枠６２上に支柱１２が立設されるので、各支柱１２が下基枠６２を介して連結されることとなる。したがって、下基枠６２と各支柱１２とからなる構造体が形成されることとなり、各支柱１２に対する支持強度が向上するものとなる。 In addition, as shown in FIG. 1, it is also possible to construct a roof surface by covering a roof surface constituting member 70 such as a sheet over the beam members 40 and the beam members 41 of the roof frame 13. Thereby, the precipitation and solar radiation to the building structure A can be prevented.
According to the present embodiment, first, the lower base frame 62 is formed so as to surround the lower end portion of the building structure A, and the support columns 12 are erected on the lower base frame 62. It will be connected via the frame 62. Therefore, a structure composed of the lower base frame 62 and each support column 12 is formed, and the support strength with respect to each support column 12 is improved.

そして、該構造体の支柱１２の上端部に屋根フレーム１３が連結されて中間構造体６０が形成されることにより、各支柱１２は屋根フレーム１３を介してもそれぞれ連結されることとなる。これにより、その後に下基枠６２を構成する根太材６１を取り外す場合にも、前記構造体が解消される一方、支柱１２を屋根フレーム１３により連結してなる新たな構造体が成立することとなり、各支柱１２及び屋根フレーム１３は当該構造体として一体となって外力に抗するものとなるのである。
したがって、本実施形態の仮設構造物１の組上げ方法によれば、支柱１２の組上げから仮設構造物１の組み上げ完了に至るまで、また、組上げが完成した後も、一定の強度を有する構造体として成立することとなり、該構造体として外力に抵抗することとなるので、仮設構造物１としての強度を一定に維持する。 Then, the roof frame 13 is connected to the upper end portion of the support column 12 of the structure to form the intermediate structure 60, so that each support column 12 is also connected through the roof frame 13. As a result, even when the joist member 61 constituting the lower base frame 62 is subsequently removed, the structure is eliminated, while a new structure is formed by connecting the column 12 with the roof frame 13. Each strut 12 and the roof frame 13 are integrated as a structure to resist external forces.
Therefore, according to the method for assembling the temporary structure 1 according to the present embodiment, the structure having a certain strength is obtained from the assembly of the support column 12 to the completion of the assembly of the temporary structure 1 and after the assembly is completed. As a result, the structure body resists external force, so that the strength of the temporary structure 1 is maintained constant.

そして、この様に支柱１２と屋根フレーム１３とによって仮設構造物１としての強度を有する構造体が構成されるからこそ、上述の如く根太材６１を取り外すことができるのである。そして、根太材６１を根柱１１から取り外して建築構造物Ａの下端部を開放状とすることにより、地上での建築構造物Ａへのアクセスの妨げとなる障害が除去され、作業者は容易に建築構造物Ａにアクセスすることができる。
また、上記仮設構造物１は、長尺な部材を連結することにより形成されるので、建築構造物Ａの周囲に複数の根柱１１を設置する狭小なスペースがあれば組み上げることができる。 And since the structure which has the intensity | strength as the temporary structure 1 is comprised by the support | pillar 12 and the roof frame 13 in this way, the joist 61 can be removed as mentioned above. Then, by removing the joist 61 from the root pillar 11 and opening the lower end of the building structure A, obstacles that hinder access to the building structure A on the ground are removed, and the operator can easily The building structure A can be accessed.
Moreover, since the said temporary structure 1 is formed by connecting an elongate member, if there is a narrow space which installs the several root pillar 11 around the building structure A, it can assemble.

したがって、本実施形態の組上げ方法によれば、周囲に十分な作業領域を確保できない崖際に建築構造物Ａが建設されている場合や、仮設構造物１の組上げの対象となる建築構造物Ａと当該建築構造物Ａに隣接する他の建築構造物Ａとの間に狭小なスペースしか確保できない場合であっても、この様な狭小なスペースに仮設構造物１が組み上げられるものとなるのである。
また、構成する部材も少なく、組上げに広大な作業領域を要することはない。
以上、本発明の実施の形態を詳述したが、本発明は上記の実施の形態に限定されるものではない。 Therefore, according to the assembling method of the present embodiment, when the building structure A is constructed on a cliff where a sufficient work area cannot be secured around the building structure A, or the building structure A that is a target for assembling the temporary structure 1 Even if only a narrow space can be secured between the building structure A and another building structure A adjacent to the building structure A, the temporary structure 1 can be assembled in such a narrow space. .
In addition, since the number of members is small, a large work area is not required for assembly.
Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the above-described embodiments.

例えば、根柱１１の数や梁材４０、桁材４１の長さは建築構造物Ａの大きさによって適宜変更が可能である。また、また、各部材間にワイヤ等を張設する構成を採用することも可能である。
また、屋根フレーム１３の構成は、建築構造物Ａの屋根面Ｒの形状に応じて適宜変更可能であり、アーチ状、片流れ状、入母屋状等に形成することも可能である。また、建築構造物Ａの屋根面Ｒの勾配に合わせて梁材４０の傾斜角度を可変とすべく、梁角度調整部材４２の傾斜面４７をジャッキや油圧シリンダ等によって平板面４６に対して傾斜角度調整自在とすることも可能である。 For example, the number of root pillars 11 and the lengths of the beam members 40 and the beam members 41 can be appropriately changed depending on the size of the building structure A. It is also possible to employ a configuration in which a wire or the like is stretched between the members.
Moreover, the structure of the roof frame 13 can be suitably changed according to the shape of the roof surface R of the building structure A, and can also be formed in an arch shape, a single-flow shape, a wardrobe shape, or the like. Further, the inclined surface 47 of the beam angle adjusting member 42 is inclined with respect to the flat plate surface 46 by a jack, a hydraulic cylinder or the like in order to make the inclination angle of the beam member 40 variable in accordance with the inclination of the roof surface R of the building structure A. It is also possible to adjust the angle freely.
