Description

本発明は、束柱を形成するための捨型枠、該捨型枠を用いた束柱の形成方法、及び該束柱の形成方法を利用する建物の解体方法に関する。 The present invention relates to a waste form for forming a bundle pillar, a method for forming a bundle pillar using the waste form, and a method for dismantling a building using the method for forming the bundle pillar.

複数階層の建物の未解体部の最上階に解体重機を投入し、上階から下階に向けて順次解体する建物の解体方法が広く行われている。ここで、解体重機が投入される階層の床面を解体重機の重量に耐えるように補強することが必要である。 A widespread method of dismantling a building is to put a demolition machine on the top floor of the undemolition part of a multi-story building and dismantle it sequentially from the upper floor to the lower floor. Here, it is necessary to reinforce the floor surface of the layer on which the demolition machine is inserted so as to withstand the weight of the demolition machine.

特許文献１には、捨型枠を上階の床スラブの下面と下階の床面との間に固定し、上階の床スラブに貫通孔を設けてこれを介して上階から捨型枠内にセメント系固結性流動物を注入することで、下階の床面上に上階の床スラブを補強する束柱を形成する方法が開示されている。 In Patent Document 1, a scraping frame is fixed between the lower surface of the floor slab on the upper floor and the floor surface on the lower floor, and a through hole is provided in the floor slab on the upper floor, and the scraping frame is formed from the upper floor through the through hole. A method of forming a bundle column for reinforcing the floor slab of the upper floor on the floor surface of the lower floor by injecting a cement-based solidified fluid into the frame is disclosed.

ここで、上階を下階から補強するには、上階の床スラブを補強するよりも、床スラブを支持する梁を束柱で補強するのが望ましい。しかし、梁には貫通孔を設けることができないため、特許文献１に開示された方法では梁を束柱で補強することができない。 Here, in order to reinforce the upper floor from the lower floor, it is preferable to reinforce the beams supporting the floor slab with bundle columns rather than reinforcing the floor slab on the upper floor. However, since the beam cannot be provided with a through hole, the beam cannot be reinforced with a bundle column by the method disclosed in Patent Document 1.

（束柱の形成方法）
捨型枠１０を用いた束柱の形成方法を説明する。 (Method of forming bundle pillars)
A method of forming a bundle column using the waste formwork 10 will be described.

まず、図３に示すように、捨型枠１０の型枠本体１１を上階１の梁１ｃと下階２の床面２ａとの間に固定する。ここで、型枠本体１１の下端に設けられた取り付け片（不図示）を下階２の床面２ａに固定し、継手部１１ａの上端に設けられた取り付け片（不図示）を梁１ｃの下面に固定する。 First, as shown in FIG. 3, the formwork body 11 of the formwork 10 is fixed between the beam 1c on the upper floor 1 and the floor surface 2a on the lower floor 2. Here, the mounting piece (not shown) provided at the lower end of the formwork body 11 is fixed to the floor surface 2a of the lower floor 2, and the mounting piece (not shown) provided at the upper end of the joint portion 11a is attached to the beam 1c. Fix it on the bottom surface.

次に、図４に示すように、補助筒１２ａ、エルボ１２ｂ、及び延長筒１２ｃを接続して補助型枠１２を構成し、その下端（すなわち、延長筒１２ｃの一端）を継手部１１ａの接続部１１ｂに嵌入して型枠本体１１に接続し、その上端を上階１の床スラブ１ａの下面に固定する。ここで、補助筒１２ａの上端に設けられた取り付け片（不図示）を、上階１の床スラブ１ａの下面に固定する。 Next, as shown in FIG. 4, the auxiliary cylinder 12a, the elbow 12b, and the extension cylinder 12c are connected to form the auxiliary formwork 12, and the lower end thereof (that is, one end of the extension cylinder 12c) is connected to the joint portion 11a. It is fitted into the portion 11b and connected to the formwork main body 11, and the upper end thereof is fixed to the lower surface of the floor slab 1a on the upper floor 1.

The number of bundle columns to be formed shall bear the weight of the demolition machine.

ここで、梁１ｃに限らず床スラブ１ａを支持する束柱（特許文献１に記載のものと同様）を合わせて設けてもよいが、梁１ｃを支持することで十分な強度となり不要であることが多い。 Here, not only the beam 1c but also a bundle column supporting the floor slab 1a (similar to that described in Patent Document 1) may be provided together, but supporting the beam 1c provides sufficient strength and is unnecessary. Often.

次に、最上階に解体重機を投入して、解体する。 Next, a dismantling machine is put on the top floor to dismantle.

次に、最上階の直下の階層の１つ下の階層に、上述と同様に複数の束柱を形成して、最上階の直下の階層の梁１ｃを支持する。 Next, in the same manner as described above, a plurality of bundle columns are formed in the layer immediately below the layer directly below the top floor to support the beam 1c in the layer directly below the top floor.

次に、解体重機を最上階の直下の階層に移動して、解体する。この際、形成された複数の束柱をも解体するものとする。 Next, the dismantling machine is moved to the floor directly below the top floor and dismantled. At this time, it is assumed that the formed plurality of bundle pillars are also dismantled.

以下、階層を１つずつ下に移動しつつ、複数の束柱を形成して梁１ｃを支持することと、支持された梁１ｃの上の階層に解体重機を投入して解体することを繰り返し、建物を上階から下階に向けて順次解体する。 After that, while moving down the hierarchy one by one, forming a plurality of bundle columns to support the beam 1c, and throwing a demolition machine into the hierarchy above the supported beam 1c and dismantling it are repeated. , The building will be demolished from the upper floor to the lower floor.

なお、複数の束柱を形成して梁１ｃを支持することは、必ずしも支持された梁１ｃの上の階層に解体重機を投入して解体する直前に行わなくともよい。例えば、最上階を除く全ての階層に複数の束柱を形成することを、最初に行ってもよい。 It should be noted that the formation of a plurality of bundle columns to support the beam 1c does not necessarily have to be performed immediately before the weight-reducing machine is put into the layer above the supported beam 1c and dismantled. For example, the formation of a plurality of bundle columns on all layers except the top floor may be performed first.

本発明の捨型枠及び束柱の形成方法によれば、上階の梁を下階の床面上で支持する束柱を形成することが可能となる。また、本発明の建物の解体方法によれば、解体重機を投入して建物を上階から下階に向けて順次解体することが可能となる。多くの建設業者による利用が考えられる。 According to the method for forming a waste formwork and a bundle column of the present invention, it is possible to form a bundle column that supports the beams on the upper floor on the floor surface of the lower floor.
