Description

本発明は建築物の解体工法に関するものである。   The present invention relates to a building demolition method.

建築物を解体するに際して、近接して建物、鉄道、道路などが存在する場合には、特に外壁の解体の工程でコンクリートの破片などが外部へ飛散する危険を避けなければならない。
そのための工法として例えば特許文献1記載の方法が公知である。
この公知の方法は図5に示すように、解体する建築物aの周囲に、影響を与えてはいけない区域が存在する場合にその区域に面する外壁bを、影響を与えない区域まで移動させてから解体する方法である。
When building is demolished, if there are buildings, railways, roads, etc. close to each other, the risk of concrete debris scattering to the outside must be avoided, especially in the process of demolishing the outer wall.
As a construction method therefor, for example, a method described in Patent Document 1 is known.
In this known method, as shown in FIG. 5, when there is an area that should not be affected around the building a to be demolished, the outer wall b facing the area is moved to an area that will not be affected. It is a method of dismantling.

特開2010−265595号公報JP 2010-265595 A

前記したような従来の建築物の解体工法にあっては、次のような問題点がある。
<1> この工法はまず外壁bや柱(以下「壁」で代表させる)の下端を水平に切断して床と縁切りを行い、その後に壁bや柱からなるブロックcを外壁に直交する方向に、安全区域まで引き寄せて、その後に安全区域内で解体する工法である。したがって外壁bの床からの切り離しと、切り離した壁を含むブロックcの解体という2工程で処理できるはずの工法である。
<2> しかし実際に実施してみると、3工程を要することが分かった。それは図6に示すように、ワイヤソーやウォールソーによって壁を床から切り離す際に、ソーの下側にも軸受などの機構が存在するから、この機械高よりも下は切断できない。すると壁の付け根、すなわち床面と同一面では切断できないため、壁の裾部dが残ることになる。
<3> 壁の裾部dが残ると、図5に示すように切断後のブロックcをスライドさせる際に、外壁bから離れる側は問題はないが、それと直交する側がスライドする軌跡は、残った裾部dと重なることになる。それでは裾部dがブロックcのスライドの障害となるので、事前に裾部dを破砕解体してスライド面を平坦に仕上げる工程が必要となる。
<4> 上記の問題は壁bだけでなく、切断後のブロックcのスライド範囲内に支柱が存在する場合も同様であって、支柱の切断後に残る裾部dも二次解体してスライド面を平坦に仕上げておかなければならない。
<5> このように従来の工法を実際に採用すると、外壁bを床から切り離す工程(一次解体)、残った裾部dを床面まで破砕してブロックcが床面上をスライド可能に整地する工程(二次解体)、そして安全区域に引き込んだブロックcを解体する工程(三次解体)という3回の解体工程が必要となることが分かった。
<6> さらに従来の方法では、床から切断したブロックcを外壁bに直交する方向に引き込む工法であるために、出隅部のブロックcではまずX方向に引き寄せ、次にY方向に引き寄せるという二段階の作業が必要であることも分かった。
The conventional building demolition method as described above has the following problems.
<1> This construction method first cuts the lower end of the outer wall b or pillar (hereinafter referred to as “wall”) horizontally to cut the edge from the floor, and then the block c composed of the wall b or pillar is perpendicular to the outer wall. It is a construction method that draws to the safe area and then dismantles in the safe area. Therefore, the construction method should be able to be processed in two steps: separation of the outer wall b from the floor and disassembly of the block c including the separated wall.
<2> However, when actually implemented, it was found that three steps were required. As shown in FIG. 6, when a wall is cut off from the floor by a wire saw or a wall saw, there is a mechanism such as a bearing on the lower side of the saw. Then, since the base of the wall, that is, the same surface as the floor surface cannot be cut, the skirt portion d of the wall remains.
<3> When the skirt d of the wall remains, there is no problem on the side away from the outer wall b when sliding the block c after cutting, as shown in FIG. It overlaps with the bottom part d. Then, since the skirt part d becomes an obstacle to the slide of the block c, a process of crushing and disassembling the skirt part d to finish the slide surface in advance is required.
<4> The above problem is the same not only when the wall b is present but also when a column is present within the slide range of the block c after cutting. Must be finished flat.
<5> Thus, when the conventional construction method is actually adopted, the step of separating the outer wall b from the floor (primary dismantling), the remaining hem d is crushed to the floor surface, and the block c is slidable on the floor surface It was found that three dismantling steps were required: a step of dismantling (secondary dismantling) and a step of dismantling the block c drawn into the safety zone (tertiary dismantling).
<6> Furthermore, in the conventional method, since the block c cut from the floor is drawn in a direction perpendicular to the outer wall b, the block c at the protruding corner is first drawn in the X direction and then drawn in the Y direction. I also found that two steps were necessary.

上記のような課題を解決する本発明の建築物の解体工法は、建築物の外壁を含むブロックを、解体中の建築物の内側に移動させてから解体する工法であって、外壁、内壁、柱など、ジャッキで支持した状態でその下端部を、裾部を残して水平に切断し、外壁は、外壁表面に直交する方向ではない、内側に斜めに引き寄せる方向と平行の方向に切断し、移動方向が、建物の外壁の表面に直交する方向ではない方向であって、かつ裾部が残っていない方向に移動させてから解体することを特徴としたものである。
また本発明の建築物の解体工法は、建築物の内外の壁あるいは支柱の表面に面接触をする鉛直板を備えた支持部材を取り付け、この鉛直板を備えた支持部材をローラ付きジャッキで支持し、内外の壁あるいは支柱の下部を水平に切断し、切断後の外壁を含むブロックをローラ付きジャッキで支持したまま、外壁より内側に、外壁の表面に直交する方向ではない方向に移動させてから解体することを特徴としたものである。
また本発明の建築物の解体工法は外壁を、外壁の表面に直交する方向でない方向で切断して行うことを特徴としたものである。
The building demolition method of the present invention that solves the above problems is a method of demolition after moving the block including the outer wall of the building to the inside of the building being demolished, the outer wall, the inner wall, Cut the lower end of the pillar, such as a pillar, horizontally, leaving the skirt, and cut the outer wall in a direction parallel to the direction of pulling diagonally inside, not perpendicular to the outer wall surface, The moving direction is a direction that is not a direction orthogonal to the surface of the outer wall of the building , and is moved in a direction in which no skirt remains, and then dismantled.
In the building demolition method of the present invention, a support member provided with a vertical plate that makes surface contact with the inner and outer walls of the building or the surface of the column is attached, and the support member provided with the vertical plate is supported by a jack with a roller. Then, cut the inner and outer walls or the lower part of the column horizontally, and move the block including the outer wall after cutting to the inside of the outer wall in a direction that is not perpendicular to the surface of the outer wall while supporting it with a jack with a roller. It is characterized by dismantling.
The building demolition method of the present invention is characterized in that the outer wall is cut in a direction that is not perpendicular to the surface of the outer wall.

本発明の建築物の解体工法は以上説明したようになるから次のような効果を得ることができる。
<1> 切断後の外壁を含むブロックを、外壁の表面に直交する方向ではない方向に移動させるから、ブロックは残った裾部の上を走行することがない。そのため従来の工法のように、壁や柱の切断後に残った裾部をさらに破砕して平坦にするような二次解体の必要がなく、直ちにブロックを外部への影響のない範囲に引き入れて解体できるので迅速で効率的な作業を行うことができる。
<2> 建築物の外壁あるいは支柱の表面に面接触をする支持部材の鉛直板を取り付けて移動させる場合には、引き寄せ力は点ではなく面でブロックに作用するから、移動中のブロックの変形が生じにくく、円滑な移動が可能となる。これがブロックにアンカーを打設して移動させる工法では、引き寄せ力が点で作用するから、ブロックが移動中に変形してスライドが困難になるような問題が生じやすい。
<3> 解体する建築物は古いものが多く、躯体のコンクリート強度が低下していることが多い。その点からも面接触式の利点がある。すなわち建築物の外壁あるいは支柱の表面に支持部材の鉛直板を取り付けて両側から圧着して移動する場合には、移動する建築物の自重を鉛直板面全体の摩擦で支持するため、建築物のコンクリート圧縮強度が低い場合でも十分対応が可能となる。
<4> これが従来のように圧着ではなく一般的なアンカーボルトを躯体に打設して移動する建築物の自重を支持する場合には、建築物のコンクリート圧縮強度が低いとアンカーボルトの耐力が期待出来ない場合がある。その結果、アンカーボルトの打設本数が増加したり、場合によっては支持部材の取り付けが出来なくなったりして対応が困難になりやすい。
<5> 外壁を含むブロックを、外壁の表面に直交する方向ではない方向、すなわち斜め方向に移動させて引き寄せると、特にX面とY面とが直交する建物の出隅部では、X面とY面とを同時に内側へ引き入れることができるので、作業がきわめて能率的である。
Since the building demolition method of the present invention is as described above, the following effects can be obtained.
<1> Since the block including the outer wall after cutting is moved in a direction that is not perpendicular to the surface of the outer wall, the block does not travel on the remaining skirt. Therefore, unlike the conventional method, there is no need for secondary dismantling that further crushes and flattens the hem remaining after cutting the walls and pillars, and the block is immediately drawn into a range that does not affect the outside. Because it can, you can work quickly and efficiently.
<2> When a vertical plate of a supporting member that makes surface contact with the outer wall of a building or the surface of a column is attached and moved, the pulling force acts on the block not on the point but on the block. Is less likely to occur and smooth movement is possible. In the construction method in which the anchor is placed on the block and moved, the pulling force acts at a point, so that there is a problem that the block is deformed during the movement and difficult to slide.
<3> Many buildings that are demolished are old, and the concrete strength of the frame is often reduced. From this point, there is an advantage of the surface contact type. In other words, when a vertical plate of a supporting member is attached to the outer wall of a building or the surface of a column and moved by crimping from both sides, the weight of the moving building is supported by the friction of the entire vertical plate surface. Even when the concrete compressive strength is low, it is possible to cope sufficiently.
<4> If this is not a conventional crimping but a general anchor bolt is placed on the housing to support its own weight, the anchor bolt's proof strength will be reduced if the concrete compressive strength of the building is low. You may not be able to expect. As a result, the number of anchor bolts to be installed is increased, and in some cases, it is difficult to attach the support member, which makes it difficult to cope with it.
<5> When the block including the outer wall is moved in a direction that is not orthogonal to the surface of the outer wall, that is, in an oblique direction, the X-plane is Since the Y plane can be drawn inward at the same time, the work is extremely efficient.

以下図面を参照にしながら本発明の建築物の解体工法の好適な実施の形態を詳細に説明する。   Hereinafter, preferred embodiments of a building demolition method according to the present invention will be described in detail with reference to the drawings.

<1>前提条件
本発明は、建築物の外壁1を含むブロック2を、解体中の建築物の内側に移動させてから解体する工法である。
その理由は前記したように、外壁1の解体中に外側へ転倒して落下する危険を避けるためであり、たとえ壁面が外側に転倒しても外部へ落下しない範囲、すなわち1階層の高さ以上の距離だけ内側へ引き寄せ、その後に解体を行うものである。
<1> Precondition The present invention is a method of dismantling after moving the block 2 including the outer wall 1 of the building to the inside of the building being dismantled.
The reason for this is to avoid the risk of falling outside and falling during dismantling of the outer wall 1, as described above. Even if the wall falls outside, it does not fall outside, that is, the height of one layer or more. The distance is drawn inward, and then dismantling is performed.

<2>ブロックの形成
本発明の方法でも公知の方法と同様に、外壁1、内壁3、柱4などのできるだけ下端部分を水平に切断する。
切断後には、1枚の床版である天井部に、外壁1、内壁3、支柱4が一体化したひとつのブロック2を構成することになる。
このブロック2を、できるだけ変形や破損させることなく、一体化を維持したまま内側に引き寄せ、安全範囲において解体するものである。
外壁1などの裾部分を切断した場合にも、前記したようにワイヤソーやウォールソーの下側にはその回転軸などが位置しているから、床面と同一面での切断は不可能で、切断後の裾部5が残るが、本発明の方法では残った裾部5を解体する工程は不要である。
<2> Formation of Block In the method of the present invention, as in the known method, the lower end portions of the outer wall 1, the inner wall 3, the pillar 4 and the like are cut horizontally as much as possible.
After cutting, one block 2 in which the outer wall 1, the inner wall 3, and the support column 4 are integrated with each other on the ceiling portion which is one floor slab is formed.
The block 2 is pulled inward while maintaining the integration without being deformed or damaged as much as possible, and disassembled in a safe range.
Even when the hem portion of the outer wall 1 or the like is cut, as described above, the rotating shaft is located below the wire saw or wall saw, so cutting on the same surface as the floor is impossible. Although the bottom 5 after cutting remains, the method of the present invention does not require a step of dismantling the remaining bottom 5.

<3>移動方向(図1)
本発明の工法では外壁1を含むブロック2の移動方向に、従来にない特徴を有する。
すなわち外壁1を含むブロック2の移動方向が、建物の外壁1の表面に直交する方向ではない方向に移動させることを特徴としたものである。
外壁1を含むブロック2をこのような斜め方向に移動させて引き寄せると、特にX面とY面とが直交する建物の出隅部では、X面とY面とを同時に内側へ引き入れることができるので、きわめて能率的である。
また移動方向が建物の外壁1の表面に直交する方向でない方向へ移動させることにより、外壁1、内壁3、柱4の裾部5が床面の残っていても移動の障害となることがない。
<3> Movement direction (Fig. 1)
The construction method of the present invention has an unprecedented feature in the moving direction of the block 2 including the outer wall 1.
That is, the moving direction of the block 2 including the outer wall 1 is moved in a direction that is not perpendicular to the surface of the outer wall 1 of the building.
When the block 2 including the outer wall 1 is moved and pulled in such an oblique direction, the X plane and the Y plane can be drawn inward at the same time, particularly at the corner of the building where the X plane and the Y plane are orthogonal to each other. So it is extremely efficient.
Further, by moving the moving direction in a direction that is not perpendicular to the surface of the outer wall 1 of the building, even if the outer wall 1, the inner wall 3, and the skirt part 5 of the pillar 4 remain on the floor, there is no obstacle to movement. .

<4>支持部材
ブロック2を移動するためには、牽引力を受ける支持部材6が必要である。
そのために、支持部材6として、断面がL字状の鉛直板61と水平板62とで構成した鋼材の板体を使用する。
この支持部材6の鉛直板61を、建築物の外壁1や支柱4の表面に面接触をする状態で取り付ける。
取り付けに際しては、鉛直板61を外壁1や柱4の片側に位置させ、反対側に当て板63を配置してその間を貫通させたボルトとナットで一体化する。
このように外壁1などに取り付ける材料を広い面を備えた鉛直板61としたから、大きな引張力が作用しても外壁1などが部分的に破損することがなく、ブロック2に安定した形状を維持させたまま移動が可能である。
断面L字状に構成した支持部材6の水平板62は、後述するジャッキ64で支持する際に機能させる。
<4> Support member In order to move the block 2, the support member 6 which receives traction force is required.
For this purpose, a steel plate made up of a vertical plate 61 and a horizontal plate 62 having an L-shaped cross section is used as the support member 6.
The vertical plate 61 of the support member 6 is attached in a state of surface contact with the outer wall 1 of the building or the surface of the column 4.
At the time of attachment, the vertical plate 61 is positioned on one side of the outer wall 1 or the column 4, the abutting plate 63 is disposed on the opposite side, and the bolts and nuts penetrated therebetween are integrated.
Since the material attached to the outer wall 1 or the like is a vertical plate 61 having a wide surface, the outer wall 1 and the like are not partially damaged even when a large tensile force is applied, and the block 2 has a stable shape. It can be moved while being maintained.
The horizontal plate 62 of the support member 6 having an L-shaped cross section is caused to function when supported by a jack 64 described later.

<5>ローラー付きジャッキ
この鉛直板61を備えた支持部材6の水平部をローラー付きジャッキ64で支持する。
ローラー付きジャッキ64とは、複数本のジャッキ64を鉛直に並立させて組み立て、その下面に水平にローラー65を配置した装置である。
このローラー付きジャッキ64を利用することによって、ジャッキ64で支持したままの重量物を引き出すことができる。
<5> Jack with roller A horizontal portion of the support member 6 including the vertical plate 61 is supported by a jack 64 with a roller.
The roller-equipped jack 64 is a device in which a plurality of jacks 64 are vertically arranged and assembled, and a roller 65 is horizontally disposed on the lower surface thereof.
By using the jack 64 with a roller, it is possible to pull out a heavy object that is supported by the jack 64.

<6>施工方法の説明
次の本発明の施工方法について説明する。
<6> Description of Construction Method The following construction method of the present invention will be described.

<7>支持部材の取り付け(図2)
まず外壁1、内壁3、柱4の表面に支持部材6の鉛直板61を取りつける。
その取り付けは前記したように外壁1の両面を鉛直板61と当て板63とで挟み、鉛直板61と外壁1と当て板63を貫通させたボルトによって強固に締め付けて圧着して一体化する。
解体工事中には建物の全周囲は足場で囲うから、当て板63の取り付けの際に、建築物の外から作業を行うことは容易である。
<7> Attaching the support member (FIG. 2)
First, the vertical plate 61 of the support member 6 is attached to the surfaces of the outer wall 1, the inner wall 3, and the pillar 4.
As described above, the both sides of the outer wall 1 are sandwiched between the vertical plate 61 and the contact plate 63 as described above, and are firmly tightened and bonded together by a bolt that penetrates the vertical plate 61, the outer wall 1, and the contact plate 63.
During the demolition work, the entire perimeter of the building is enclosed by a scaffold, so it is easy to work from outside the building when attaching the pad plate 63.

<8>ジャッキで支持(図2)
支持部材6の水平板62の下にローラー付きジャッキ64を位置させ、ジャッキ64を延長して支持部材6の水平板62をその下から支持する。
ジャッキ64で支持したブロック2の移動を容易にするために、ローラーの下面には移動方向に沿ってレールや鉄板を敷設しておく。
<8> Supported by jack (Fig. 2)
A jack 64 with a roller is positioned under the horizontal plate 62 of the support member 6, and the jack 64 is extended to support the horizontal plate 62 of the support member 6 from below.
In order to facilitate the movement of the block 2 supported by the jack 64, rails and iron plates are laid along the movement direction on the lower surface of the roller.

<9>壁の水平切断(図3)
ローラー付きジャッキ64で支持した状態で、内外の壁1あるいは支柱4の下部を、ウォールソー、ワイヤソーなどを利用して水平に切断する。
前記したように機械の構造上、壁1や柱4を床面と同一面で切断することはできないから、壁1の切断後には帯状の裾部5が、柱4の切断後には矩形の裾部5が残ることになるが、本発明の工法であればそれらが残っても問題がない。
<9> Horizontal cutting of wall (Fig. 3)
While being supported by the jack 64 with a roller, the inner and outer walls 1 or the lower portions of the columns 4 are horizontally cut using a wall saw, a wire saw, or the like.
As described above, the wall 1 and the pillar 4 cannot be cut in the same plane as the floor surface due to the structure of the machine, so that the strip-like skirt 5 is cut after the wall 1 is cut, and the rectangular skirt is cut after the pillar 4 is cut. Although the part 5 remains, there is no problem even if they remain if it is the construction method of the present invention.

<10>外壁の鉛直切断(図1)
それと前後して外壁1の二か所を、外壁1の表面に直交する方向でない方向で切断する。
その方向とは、外壁1を含むブロック2を建築物に内側に斜めに引き寄せる場合の方向と平行の方向である。
こうして壁1と柱4の下部を水平に切断し、さらに外壁1の二か所を、外壁1の表面に直交する方向でない方向に切断することによって、共通の天井スラブと一体化した、外壁1、内壁3、あるいは柱4を含むひとつの移動のためのブロック2を既存建物から分離させて形成することができる。
<10> Vertical cutting of outer wall (Fig. 1)
Before and after that, the two portions of the outer wall 1 are cut in directions that are not perpendicular to the surface of the outer wall 1.
The direction is a direction parallel to the direction in which the block 2 including the outer wall 1 is drawn obliquely inward to the building.
Thus, the outer wall 1 integrated with the common ceiling slab is obtained by cutting the wall 1 and the lower part of the pillar 4 horizontally and further cutting the two portions of the outer wall 1 in directions that are not perpendicular to the surface of the outer wall 1. The block 2 for movement including the inner wall 3 or the pillar 4 can be separated from the existing building.

<11>ブロック2の支持(図3)
建築物の一部を、水平線、鉛直線で切断した後の外壁1を含むブロック2は、事前に支持部材6を介してローラー付きジャッキ64で支持してある。
したがって切断後にブロック2が下降したり転倒することはない。
<11> Support of block 2 (FIG. 3)
A block 2 including an outer wall 1 after a part of a building is cut along a horizontal line and a vertical line is supported by a jack 64 with a roller via a support member 6 in advance.
Therefore, the block 2 does not descend or fall after cutting.

<12>斜め引き込み(図1、4)
次にローラー付きジャッキ64を内側に、外壁1の表面に直交する方向ではない方向に移動させる。
そのために例えばローラー付きジャッキ64にPC鋼棒73を取り付け、床面に反力アンカー7を打設して固定した牽引用のセンターホールジャッキ71によって牽引する。
すると1枚の天井スラブと一体化した外壁1、内壁3、支柱4からなるブロック2を、建物の外側から十分に離れた内部に引き込むことができる。
その際に床の上には、壁や柱4の切断後の裾部5が残っている。
しかし前記したように本発明の工法ではブロック2の移動方向が外壁1の表面と直交しない、というだけで、移動方向は自由に選択できる。
したがってそれらの裾部5が残っていない方向にレールを平行に敷設しておいて引き寄せることができ、裾部5の破砕の工程を要しない。
<12> Diagonal pull-in (Figs. 1 and 4)
Next, the jack with roller 64 is moved inward in a direction that is not perpendicular to the surface of the outer wall 1.
For this purpose, for example, a PC steel rod 73 is attached to the roller-equipped jack 64, and the reaction force anchor 7 is driven and fixed on the floor surface and pulled by a center hole jack 71 for towing.
Then, the block 2 consisting of the outer wall 1, the inner wall 3, and the support column 4 integrated with one ceiling slab can be drawn into the interior sufficiently away from the outside of the building.
At that time, the skirt 5 after cutting the wall and the pillar 4 remains on the floor.
However, as described above, in the method of the present invention, the moving direction of the block 2 is not perpendicular to the surface of the outer wall 1, and the moving direction can be freely selected.
Therefore, the rails can be laid in parallel in the direction in which the skirts 5 do not remain and can be drawn, and the process of crushing the skirts 5 is not required.

<13>内部でのブロックの解体
こうして少なくとも外壁1を含むブロック2の1階高よりも長い距離だけ内側に引き込んでおき、その後に公知の方法で解体する。
それだけ引き込んでおけば、外壁1が解体中に外側に転倒しても、建築物の外部へ落下することがなく、安全に解体を行うことができる。
<13> Disassembling the block inside In this way, the block 2 including at least the outer wall 1 is drawn inward by a distance longer than the first floor height, and then disassembled by a known method.
If it draws in so much, even if the outer wall 1 falls outside during the dismantling, it does not fall outside the building and can be dismantled safely.
