特開２０１５−１０８２５９JP 2015-108259

近頃、３階建てのツーバイフォー建物が多く建築されるようになってきた。
このような高いツーバイフォー建物では地震時等に壁体の下端に作用する引き抜き力が大きくなるため、あらかじめ基礎コンクリートにアンカーボルトを植設することで、アンカーボルトの引き抜き耐力を高めた工法が用いられている。Recently, many three-story two-by-four buildings have been built.
In such a high two-by-four building, the pull-out force acting on the lower end of the wall body becomes large in the event of an earthquake, etc. ing.

特許文献１に記載された壁体建て起こし装置では、壁体を建て起こした状態で壁体の底面を支持すると共に、壁体を降下させる壁体降下手段を備えるので、建て起こした壁体をアンカーボルトの上から降下させて壁体の貫通孔にアンカーボルトを挿通することができる。そのため、基礎に予めアンカーボルトを植設したツーバイフォー建物の場合でも壁体の建て起こしが可能となった。 The wall body raising device described in Patent Document 1 is provided with a wall body lowering means for supporting the bottom surface of the wall body in a state where the wall body is raised and lowering the wall body. Anchor bolts can be inserted into the through holes of the wall body by lowering them from above the anchor bolts. Therefore, even in the case of a two-by-four building in which anchor bolts are planted in advance on the foundation, it is possible to build up the wall body.

しかし、特許文献１に記載された壁体建て起こし装置では、施工現場で油圧発生装置を必要とすると共に、壁パネルに壁建て起こし装置を設置、取り外すため多くの手間と時間が必要であり費用と効率の面で問題があった。 However, the wall-building device described in Patent Document 1 requires a flood control generator at the construction site, and requires a lot of labor and time to install and remove the wall-building device on the wall panel, which is costly. There was a problem in terms of efficiency.

このような問題を解決するため、床にアンカーボルトが植設されている場合でも、壁パネルを壁起こしすることが可能な壁起こし工法を提供することを課題とする。 In order to solve such a problem, it is an object of the present invention to provide a wall raising method capable of raising a wall panel even when anchor bolts are planted on the floor.

かかる課題を解決するため、請求項１に記載の発明は、ツーバイフォー建物の壁起こし工法において、壁パネルの下枠のアンカーボルトを挿入する位置にアンカーボルト貫通孔を開けると共に、基礎に埋め込んだアンカーボルトの土台上部の床合板から突き出した部分に所定の外径、内径、パイプ肉厚、長さを有する金属製のパイプの中央部を所定寸法の半径で９０度に折り曲げたアンカーパイプの一端を挿入し、前記アンカーパイプの他端を、床合板の上に水平に載置された壁パネルの下枠に空けたアンカーボルト貫通孔に挿入し、壁パネルの上枠に、壁起こし工具の受けを挿入し、壁起こし工具にツーバイフォー材を差し込み、ツーバイフォー材の下端に止め板を固定し、ハンドルを上下に動かすことにより、壁起こし工具がツーバイフォー材を抱え込むようにして除々に上昇し、壁起こし工具の受けが上枠を持ち上げることにより壁パネルが下枠を中心として回動し壁パネルを立て起こすことにより壁パネルの下枠に開けたアンカーボルト貫通孔がアンカーパイプの曲がった形状に沿って案内されて、アンカーボルト貫通孔にアンカーパイプの前記一端が挿入され土台上部の床合板に壁パネルの下枠を載せたあと、アンカーパイプを壁パネルの下枠から引き抜き、アンカーボルトに座金とナットを取り付け、壁パネルを基礎に固定したことを特徴とする。In order to solve such a problem, the invention according to claim 1 is an anchor bolt through hole at a position where an anchor bolt is inserted in a lower frame of a wall panel and an anchor embedded in a foundation in a wall raising method for a two-by-four building. One end of an anchor pipe in which the central part of a metal pipe having a predetermined outer diameter, inner diameter, pipe wall thickness, and length is bent at 90 degrees with a radius of a predetermined dimension at a portion protruding from the floor plywood at the upper part of the base of the bolt. The other end of the anchor pipe is inserted into the anchor bolt through hole made in the lower frame of the wall panel horizontally placed on the floor plywood, and the wall raising tool is received in the upper frame of the wall panel. Insert the two-by-four material into the wall-raising tool, fix the stop plate to the lower end of the two-by-four material, and move the handle up and down so that the wall-raising tool gradually rises to hold the two-by-four material and raises the wall. When the tool receiver lifts the upper frame, the wall panel rotates around the lower frame, and when the wall panel is raised, the anchor bolt through holes made in the lower frame of the wall panel follow the curved shape of the anchor pipe. Guided, the one end of the anchor pipe is inserted into the anchor bolt through hole, the lower frame of the wall panel is placed on the floor plywood at the top of the base, the anchor pipe is pulled out from the lower frame of the wall panel, and the anchor bolt has a seat and a nut. The feature is that the wall panel is fixed to the foundation.

請求項１に記載の発明によれば、ツーバイフォー建物の壁起こし工法において、壁パネルの下枠のアンカーボルトを挿入する位置にアンカーボルト貫通孔を開けると共に、基礎に埋め込んだアンカーボルトの土台上部の床合板から突き出した部分に所定の外径、内径、パイプ肉厚、長さを有する金属製のパイプの中央部を所定寸法の半径で９０度に折り曲げたアンカーパイプの一端を挿入し、前記アンカーパイプの他端を、床合板の上に水平に載置された壁パネルの下枠に空けたアンカーボルト貫通孔に挿入し、壁パネルの上枠に、壁起こし工具の受けを挿入し、壁起こし工具にツーバイフォー材を差し込み、ツーバイフォー材の下端に止め板を固定し、ハンドルを上下に動かすことにより、壁起こし工具がツーバイフォー材を抱え込むようにして除々に上昇し、壁起こし工具の受けが上枠を持ち上げることにより壁パネルが下枠を中心として回動し壁パネルを立て起こすことにより壁パネルの下枠に開けたアンカーボルト貫通孔がアンカーパイプの曲がった形状に沿って案内されて、アンカーボルト貫通孔にアンカーパイプの前記一端が挿入され土台上部の床合板に壁パネルの下枠を載せたあと、アンカーパイプを壁パネルの下枠から引き抜き、アンカーボルトに座金とナットを取り付け、壁パネルを基礎に固定したことにより、簡単な構造で安価な工具を用いて大工さんが一人で容易に壁パネルを壁起こしすることが可能となった。According to the invention of claim 1, in the wall raising method of a two-by-four building, an anchor bolt through hole is formed at a position where an anchor bolt is inserted in the lower frame of the wall panel, and an anchor bolt base upper portion embedded in the foundation is formed. One end of an anchor pipe, which is a metal pipe having a predetermined outer diameter, inner diameter, pipe wall thickness, and length and bent at 90 degrees with a radius of a predetermined dimension, is inserted into a portion protruding from the floor plywood. Insert the other end of the pipe into the anchor bolt through hole made in the lower frame of the wall panel placed horizontally on the floor plywood, insert the wall raising tool receiver into the upper frame of the wall panel, and insert the wall. By inserting the two-by-four material into the raising tool, fixing the stop plate to the lower end of the two-by-four material, and moving the handle up and down, the wall raising tool gradually rises as if holding the two-by-four material, and the receiver of the wall raising tool rises. By lifting the frame, the wall panel rotates around the lower frame, and by raising the wall panel, the anchor bolt through holes made in the lower frame of the wall panel are guided along the curved shape of the anchor pipe, and the anchor is anchored. After the one end of the anchor pipe is inserted into the bolt through hole and the lower frame of the wall panel is placed on the floor plywood on the upper part of the base, the anchor pipe is pulled out from the lower frame of the wall panel, the seat metal and nut are attached to the anchor bolt, and the wall panel.
