Description
本発明は、仮設足場を用いた建物の解体作業時に発生する解体材の飛散を防止する飛散防止装置およびこれを用いた養生方法に関するものである。 The present invention relates to a scattering prevention device that prevents scattering of a dismantling material that occurs during dismantling work of a building using a temporary scaffold, and a curing method using the scattering prevention device.
従来、建物の解体作業時に発生する解体材の飛散を防止するため、仮設足場を利用して防護ネットを設ける技術が提案されている。例えば、特開２０１８−０４０１６９号公報には、仮設足場に取り付けられて鉛直方向に伸縮可能な複数の支柱と、複数の支柱間に架設されるワイヤと、複数の支柱およびワイヤに保持された防護ネットと、を備える飛散防止装置が提案されている（特許文献１）。 BACKGROUND ART Conventionally, there has been proposed a technique of providing a protective net by using a temporary scaffold in order to prevent the dismantling material from scattering during the dismantling work of a building. For example, in Japanese Unexamined Patent Application Publication No. 2018-040169, a plurality of pillars attached to a temporary scaffold and capable of expanding and contracting in the vertical direction, a wire installed between the plurality of pillars, and a plurality of pillars and a protection held by the wires are disclosed. A scattering prevention device including a net has been proposed (Patent Document 1).
特許文献１には、防護ネットを展張させる具体的な方法は開示されていないものの、防護ネットの上端縁に沿ってワイヤを挿通させ、当該ワイヤを各支柱の上端部に設けられたアイボルトに挿通させた後、入れ子状に分割された複数段の支柱を一段ずつ上方へ向けて伸ばすことによって展張していると考えられる。 Although Patent Document 1 does not disclose a specific method for expanding the protective net, a wire is inserted along the upper edge of the protective net, and the wire is inserted into an eyebolt provided at the upper end of each column. After this, it is considered that the columns are extended by expanding the nested columns into a plurality of columns up one step at a time.
しかしながら、防護ネットと支柱を同時に持ち上げるには、かなりの力が必要となるため、作業者の負担が大きく、大人数が必要であるという問題がある。また、防護ネットを高い位置まで展張するには、入れ子状の支柱を複数回に渡って上方へ伸ばす必要があるため、展張作業が煩雑となり時間がかかるという問題もある。さらに、伸縮可能に構成された入れ子状の支柱を多数本用意するには、コストが高いという問題もある。よって、実用性に乏しかった。 However, since a considerable amount of force is required to lift the protective net and the support at the same time, there is a problem that the burden on the operator is large and a large number of people are required. In addition, in order to extend the protective net to a high position, it is necessary to extend the nested support column upwards a plurality of times, which causes a problem that the extension work is complicated and takes time. Further, there is a problem that the cost is high in preparing a large number of telescopic columns that are configured to be expandable and contractible. Therefore, it was not practical.
本発明は、このような問題点を解決するためになされたものであって、安価で簡素な構成でありながら簡単かつ迅速に養生ネットを展張し、解体材の飛散を防止することができる飛散防止装置およびこれを用いた養生方法を提供することを目的としている。 The present invention has been made in order to solve such a problem, and can spread a curing net easily and quickly with a cheap and simple structure, and can prevent the dismantling material from scattering. An object of the present invention is to provide a prevention device and a curing method using the same.

以下、本発明に係る飛散防止装置およびこれを用いた養生方法の実施形態について図面を用いて説明する。 Embodiments of a shatterproof device and a curing method using the same according to the present invention will be described below with reference to the drawings.
本発明に係る飛散防止装置１は、図１に示すように、仮設足場を用いた建物の解体作業時に発生する解体材の飛散を防止するものである。本実施形態において、飛散防止装置１は、図２に示すように、所定間隔を隔てて並設される複数本の支柱パイプ２と、これら支柱パイプ２のそれぞれに挿通される操作ワイヤ３と、各操作ワイヤ３の先端部に取り付けられる養生ネット４とを有している。以下、各構成について説明する。 As shown in FIG. 1, a scattering prevention device 1 according to the present invention prevents scattering of dismantling material that occurs during dismantling work of a building using a temporary scaffold. In this embodiment, as shown in FIG. 2, the anti-scattering device 1 includes a plurality of support pipes 2 arranged in parallel at a predetermined interval, and an operation wire 3 inserted into each of the support pipes 2. It has a curing net 4 attached to the tip of each operation wire 3. Hereinafter, each configuration will be described.
支柱パイプ２は、図４に示すように、複数段に組まれた仮設足場のうち最上段にある建枠１０の上端連結部１１に連結されるものである。本実施形態において、支柱パイプ２は、中空状のアルミパイプによって構成されており、図２に示すように、その外周面の上方位置と下方位置には、操作ワイヤ３の先端部および基端部をそれぞれ挿通するワイヤ挿通孔２１が形成されている。 As shown in FIG. 4, the pillar pipe 2 is connected to the upper end connecting portion 11 of the building frame 10 in the uppermost stage of the temporary scaffolds assembled in a plurality of stages. In the present embodiment, the support pipe 2 is composed of a hollow aluminum pipe, and as shown in FIG. 2, the distal end portion and the proximal end portion of the operation wire 3 are located above and below the outer peripheral surface thereof. Wire insertion holes 21 through which the respective wires are inserted are formed.
また、支柱パイプ２の下端側は、建枠１０の上端連結部１１に抜き差し可能な内径を有しているとともに、上端連結部１１に設けられた連結ピン１２を挿通させて連結するためのピン挿通孔２２を有している。なお、本実施形態では、施工性を高めるため、支柱パイプ２の下端部を建枠１０の上端連結部１１に差し込んで連結しているが、この構成に限定されるものではなく、連結クランプ等を用いて支柱パイプ２の下端部と建枠１０の上端連結部１１とを連結してもよい。 Further, the lower end side of the pillar pipe 2 has an inner diameter capable of being inserted into and removed from the upper end connecting portion 11 of the building frame 10, and a pin for inserting and connecting the connecting pin 12 provided in the upper end connecting portion 11 It has an insertion hole 22.

You may connect the lower end part of the support pipe 2 and the upper end connection part 11 of the building frame 10 using.
さらに、本実施形態において、支柱パイプ２の外周面には、図２に示すように、長手方向に沿って所定間隔を隔てて複数の連通孔２３が設けられている。この連通孔２３は、養生ネット４の側縁部を縛り付けて固定するための固定ヒモ（図示せず）等を連通させるようになっている。 Further, in the present embodiment, as shown in FIG. 2, a plurality of communication holes 23 are provided on the outer peripheral surface of the support pipe 2 at predetermined intervals along the longitudinal direction. The communication hole 23 is adapted to communicate with a fixed string (not shown) or the like for binding and fixing the side edge portion of the curing net 4.
操作ワイヤ３は、養生ネット４の昇降作業を操作するためのワイヤである。本実施形態において、操作ワイヤ３は、図２に示すように、支柱パイプ２に挿通されており、先端部が支柱パイプ２の上方位置に設けられたワイヤ挿通孔２１から出ているとともに、基端部が支柱パイプ２の下方位置に設けられたワイヤ挿通孔２１から出ている。 The operation wire 3 is a wire for operating the lifting operation of the curing net 4. In the present embodiment, as shown in FIG. 2, the operation wire 3 is inserted into the support pipe 2, and the tip end thereof is output from the wire insertion hole 21 provided above the support pipe 2, and The end portion is projected from the wire insertion hole 21 provided at the lower position of the support pipe 2.
なお、本実施形態では、支柱パイプ２の上下に設けられたワイヤ挿通孔２１から操作ワイヤ３の先端部と基端部を引き出しているが、この構成に限定されるものではない。具体的には、操作ワイヤ３の先端部を支柱パイプ２の上端開口から出してもよい。また、上述した連結クランプ等によって支柱パイプ２の下端部と建枠１０の上端連結部１１とを連結する場合には、操作ワイヤ３の基端部を支柱パイプ２の下端開口から出してもよい。 In the present embodiment, the distal end portion and the proximal end portion of the operation wire 3 are drawn out from the wire insertion holes 21 provided on the upper and lower sides of the support pipe 2, but the configuration is not limited to this. Specifically, the tip portion of the operation wire 3 may be projected from the upper end opening of the support pipe 2. Further, when the lower end portion of the support pipe 2 and the upper end connection portion 11 of the building frame 10 are connected by the above-described connecting clamp or the like, the base end portion of the operation wire 3 may be extended from the lower end opening of the support pipe 2. ..
また、本実施形態において、操作ワイヤ３の先端部には、図２に示すように、養生ネット４と連結するための連結具５が取り付けられている。この連結具５は、図３（ａ）に示すように、略Ｃ字形状の本体部材５１と、この本体部材５１の開口部５２を開閉する開閉部材５３とを有している。本実施形態において、開閉部材５３は、開口部５２を閉じる方向にバネの弾力で付勢されており、内方へ押し込むと開口部５２を開くようになっている。 Further, in the present embodiment, a connecting tool 5 for connecting with the curing net 4 is attached to the distal end portion of the operation wire 3, as shown in FIG. As shown in FIG. 3A, the connecting tool 5 has a substantially C-shaped main body member 51 and an opening / closing member 53 that opens and closes an opening 52 of the main body member 51. In the present embodiment, the opening / closing member 53 is biased by the elastic force of the spring in the direction of closing the opening 52, and opens the opening 52 when pushed inward.
なお、連結具５は上記構成に限定されるものではなく、図３（ｂ）に示すように、開閉部材５３として長ナットを採用し、この長ナットを回動させることで、本体部材５１の開口部５２を開閉させてもよい。あるいは、養生ネット４を取り外す必要がない場合には、操作ワイヤ３の先端部を養生ネット４に直接結び付けて取り付けてもよい。 The connector 5 is not limited to the above configuration, and as shown in FIG. 3B, a long nut is used as the opening / closing member 53, and the long nut is rotated to rotate the main member 51. The opening 52 may be opened and closed. Alternatively, when it is not necessary to remove the curing net 4, the tip of the operation wire 3 may be attached directly to the curing net 4.
養生ネット４は、解体作業時に飛散する解体材を受け止めるものである。本実施形態において、養生ネット４は、ポリエステル製のラッセルネット等によって構成されており、図２に示すように、連結具５を介して各操作ワイヤ３の先端部に取り付けられて吊り下げられるようになっている。 The curing net 4 receives the dismantled material scattered during the dismantling work. In the present embodiment, the curing net 4 is composed of a polyester Russell net or the like, and as shown in FIG. It has become.
つぎに、本実施形態の飛散防止装置１の作用、および飛散防止装置１を用いた養生方法について説明する。 Next, the operation of the shatterproof device 1 of the present embodiment and the curing method using the shatterproof device 1 will be described.
本実施形態の飛散防止装置１を用いて、解体しようとする建物の周囲を養生する場合、まず、図４に示すように、複数段に組まれた仮設足場のうち最上段にある建枠１０の上端連結部１１に支柱パイプ２を連結し、複数本の支柱パイプ２を所定間隔を隔てて並設する（支柱パイプ連結工程）。このとき、支柱パイプ２の下端部を建枠１０の上端連結部１１に差し込むだけで、連結ピン１２がピン挿通孔２２から突出するため、簡単かつ迅速に連結される。また、この段階では、養生ネット４を取り付けていないため、軽量で作業員の負担が小さい。 When the surroundings of the building to be demolished are cured using the shatterproof device 1 of the present embodiment, first, as shown in FIG. 4, among the temporary scaffolds assembled in a plurality of stages, the building frame 10 in the uppermost stage is used. The support pipe 2 is connected to the upper end connecting portion 11 of the above, and a plurality of support pipes 2 are arranged side by side at predetermined intervals (support pipe connecting step). At this time, the connecting pin 12 projects from the pin insertion hole 22 only by inserting the lower end portion of the support pipe 2 into the upper end connecting portion 11 of the building frame 10, and thus the connection is simple and quick. Further, at this stage, since the curing net 4 is not attached, the weight is light and the burden on the worker is small.
つぎに、図５に示すように、各操作ワイヤ３の先端部に養生ネット４を取り付ける（養生ネット取付工程）。このとき、本実施形態では、操作ワイヤ３の先端部に取り付けられた連結具５が、開閉部材５３によって容易に開口部５２を開閉するため、養生ネット４が簡単かつ迅速に取り付けられる。 Next, as shown in FIG. 5, the curing net 4 is attached to the tip of each operation wire 3 (curing net attaching step). At this time, in the present embodiment, the connector 5 attached to the distal end of the operation wire 3 easily opens and closes the opening 52 by the opening / closing member 53, so that the curing net 4 can be easily and quickly attached.
つづいて、図６に示すように、各操作ワイヤ３の基端部を引っ張って養生ネット４を引き上げる（操作ワイヤ引張工程）。これにより、養生ネット４が支柱パイプ２の上端部から吊り下げられ、略鉛直方向に沿って展張された状態となる。このとき、作業者は操作ワイヤ３を一本ずつ引き上げるだけでよく、展張作業が簡易化および迅速化する。また、養生ネット４は比較的軽量のため、操作ワイヤ３は軽い力でスムーズに引っ張ることができる。 Subsequently, as shown in FIG. 6, the base end portion of each operation wire 3 is pulled to pull up the curing net 4 (operation wire pulling step). As a result, the curing net 4 is suspended from the upper end portion of the support pipe 2 and is stretched in the substantially vertical direction. At this time, the operator only has to pull up the operation wires 3 one by one, and the spreading work is simplified and speeded up. Further, since the curing net 4 is relatively lightweight, the operation wire 3 can be smoothly pulled with a light force.
さらに、本実施形態では、ワイヤ挿通孔２１から引き出した操作ワイヤ３の先端部に連結具５を取り付けている。このため、誤って操作ワイヤ３の基端部を引っ張り過ぎた場合でも、連結具５がワイヤ挿通孔２１で引っ掛かり、操作ワイヤ３の先端部が支柱パイプ２の内部に入り込むのを防止する。 Further, in the present embodiment, the connecting tool 5 is attached to the distal end portion of the operation wire 3 pulled out from the wire insertion hole 21. Therefore, even if the proximal end portion of the operation wire 3 is accidentally pulled too much, the connector 5 is prevented from being caught in the wire insertion hole 21 and the distal end portion of the operation wire 3 entering the inside of the support pipe 2.
養生ネット４を引き上げた後は、引っ張った各操作ワイヤ３の基端部を建枠１０等に繋ぎ止めて固定する（操作ワイヤ固定工程）。これにより、養生ネット４が略鉛直方向に沿って展張された状態で保持される。また、本実施形態では、支柱パイプ２の連通孔２３に挿通させた固定ヒモ（図示せず）によって、養生ネット４の側縁部を縛り付ける。これにより、養生ネット４が風等によって揺動しにくくなり、解体材の飛散防止機能を安定的に維持する。 After pulling up the curing net 4, the proximal ends of the pulled operation wires 3 are fixed to the building frame 10 and the like (operation wire fixing step). As a result, the curing net 4 is held in a stretched state along the substantially vertical direction. In addition, in the present embodiment, the side edge portion of the curing net 4 is bound by a fixed string (not shown) inserted through the communication hole 23 of the support pipe 2. As a result, the curing net 4 is less likely to swing due to the wind or the like, and the dispersal material scattering prevention function is stably maintained.
以上のような本実施形態によれば、以下のような効果を奏する。
１．安価で簡素な構成でありながら簡単かつ迅速に養生ネット４を展張し、解体材の飛散を防止することができる。
２．操作ワイヤ３の先端部が支柱パイプ２の内部に入り込むのを防止するとともに、操作ワイヤ３の先端部に養生ネット４を簡単かつ迅速に取り付けることができる。
３．養生ネット４が展張された状態を保持し、解体材の飛散防止機能を安定的に維持することができる。
４．既存の建枠１０に支柱パイプ２を簡単かつ迅速に連結することができる。
５．作業員が一人でも無理なく安全に養生ネット４を展張することができる。
According to this embodiment as described above, the following effects are obtained.
1. Although the structure is inexpensive and simple, the curing net 4 can be spread easily and quickly to prevent the dismantling material from scattering.
2. The tip of the operation wire 3 can be prevented from entering the inside of the support pipe 2, and the curing net 4 can be easily and quickly attached to the tip of the operation wire 3.
3. It is possible to maintain the stretched state of the curing net 4 and to stably maintain the scattering prevention function of the dismantled material.
4. The support pipe 2 can be easily and quickly connected to the existing building frame 10.
