Description

本発明は、構造部材を支持する支保装置及び支保工法に関する。 The present invention relates to a support device and a support method for supporting a structural member.

地面に立設された管状の柱材にスクリュージャッキを設け、型枠を支持する大引をスクリュージャッキで支持する型枠支保工がある（例えば、特許文献１参照）。 There is a formwork supporting work in which a screw jack is provided on a tubular column member standing on the ground and a large jack that supports the formwork is supported by the screw jack (for example, see Patent Document 1).

特許文献１の構成では、１本の大引が複数のスクリュージャッキで支持されることにより架設されている。そして、スクリュージャッキを動かすことで、大引の高さ調整を行っている。 In the configuration of Patent Document 1, one large fork is constructed by being supported by a plurality of screw jacks. And the height adjustment is performed by moving the screw jack.

また、支保工の他の例として、柱材の上部にスクリュージャッキを設けると共に複数のスクリュージャッキ間に大引としての角パイプを架設し、この角パイプで直接、構造部材（一例として鉄骨）を受けるものがある。 As another example of the support work, a screw jack is provided on the upper part of the pillar material, and a square pipe as a large pull is installed between a plurality of screw jacks, and a structural member (a steel frame as an example) is directly formed by the square pipe. There is something to receive.

しかし、これらの支保工では、構造部材が大引に載置されるだけであり、構造部材の位置決めを行う手段が設けられていない。このため、構造部材の高さ調整は行えるが、構造部材の水平方向の位置を正確に保持することが難しく、複数回の位置調整が必要となり、構造部材を効率よく保持することができなかった。さらに、構造部材の水平方向の位置を正確に保持することが難しいため、隣接する構造部材の間隔を正確に保持することができなかった。 However, in these support works, the structural member is merely placed on the large scale, and no means for positioning the structural member is provided. For this reason, although the height of the structural member can be adjusted, it is difficult to accurately hold the horizontal position of the structural member, and it is necessary to adjust the position multiple times, and the structural member cannot be efficiently held. . Furthermore, since it is difficult to accurately hold the position of the structural member in the horizontal direction, the interval between the adjacent structural members cannot be accurately held.

同様に、第３支持プレート３４は、略矩形の板材であり、Ｄ方向に沿った上辺部３４Ａには、下方向に向けて切り込まれた縦長スリット状の第５差込部３４Ｂ、３４ＣがＤ方向に間隔をあけて形成されている。また、第３支持プレート３４のＤ方向に沿った下辺部３４Ｄには、下方側へ突出した第４板片３４Ｅ、３４ＦがＤ方向に間隔をあけて形成されている。 Similarly, the third support plate 34 is a substantially rectangular plate material, and the upper side portion 34A along the D direction has fifth elongated insertion portions 34B and 34C in the form of vertically long slits cut downward. It is formed at intervals in the D direction. Further, on the lower side portion 34D along the D direction of the third support plate 34, fourth plate pieces 34E and 34F projecting downward are formed at intervals in the D direction.

図４（Ｅ）に示すように、第４支持プレート３５は、上部３５Ａの中央にアーチ部材１２又は斜材１４（図２参照）が嵌る切込部３７が形成されている。また、第４支持プレート３５は、平坦な下辺部３５Ｂに上方向に向けて切り込まれた縦長のスリット部３５Ｃ、３５Ｄが、Ｃ方向に間隔をあけて形成されている。 As shown in FIG. 4 (E), the fourth support plate 35 has a cut portion 37 into which the arch member 12 or the diagonal member 14 (see FIG. 2) fits in the center of the upper portion 35A. Further, the fourth support plate 35 is formed with vertically long slit portions 35C and 35D cut in the flat lower side portion 35B with an interval in the C direction.

同様に、第４支持プレート３６は、上部３６Ａの中央にアーチ部材１２又は斜材１４（図２参照）が嵌る切込部３８が形成されている。また、第４支持プレート３６は、平坦な下辺部３６Ｂに上方向に向けて切り込まれた縦長のスリット部３６Ｃ、３６Ｄが、Ｃ方向に間隔をあけて形成されている。なお、本実施形態では一例として、切込部３７と切込部３８が同じ大きさ（形状）であるため、切込部３７について説明し、切込部３８の説明を省略する。 Similarly, the fourth support plate 36 is formed with a cut portion 38 into which the arch member 12 or the diagonal member 14 (see FIG. 2) fits in the center of the upper portion 36A. Further, the fourth support plate 36 is formed with vertically long slit portions 36C, 36D cut upward in a flat lower side portion 36B with a gap in the C direction. In the present embodiment, as an example, since the notch 37 and the notch 38 have the same size (shape), the notch 37 will be described, and the description of the notch 38 will be omitted.

図３（Ａ）に示すように、第４支持プレート３５の下辺部３５Ｂを水平に配置した状態で、切込部３７は、側壁３７Ａ、底壁３７Ｂ、側壁３７Ｃ、及び傾斜壁３７Ｄで構成されている。側壁３７Ａは、鉛直方向に直立しており、底壁３７Ｂは、側壁３７Ａの下端に連続して水平方向に配置されている。また、側壁３７Ｃは、底壁３７Ｂにおける側壁３７Ａ側とは反対側で鉛直方向に直立しており、傾斜壁３７Ｄは、側壁３７Ｃの上端から鉛直方向に対して角度θで側壁３７Ａから離れる方向に傾斜している。 As shown in FIG. 3A, the notch 37 is composed of a side wall 37A, a bottom wall 37B, a side wall 37C, and an inclined wall 37D with the lower side part 35B of the fourth support plate 35 arranged horizontally. ing. The side wall 37A stands upright in the vertical direction, and the bottom wall 37B is disposed in the horizontal direction continuously to the lower end of the side wall 37A. Further, the side wall 37C stands upright in the vertical direction on the side opposite to the side wall 37A side of the bottom wall 37B, and the inclined wall 37D extends away from the side wall 37A at an angle θ with respect to the vertical direction from the upper end of the side wall 37C. It is inclined.

さらに、底壁３７Ｂの水平方向の幅Ｗ１は、嵌められる（挿入される）ウェブ１２Ａの水平方向の幅Ｗ２よりも大きくなるように設定されている。そして、側壁３７Ａと傾斜壁３７Ｄとの間（幅）は、Ｗ１よりも大きくなっている。これにより、ウェブ１２Ａを切込部３７内に嵌める（挿入する）とき、ウェブ１２Ａと切込部３７が接触することが抑制されている。 Furthermore, the horizontal width W1 of the bottom wall 37B is set to be larger than the horizontal width W2 of the web 12A to be fitted (inserted). The space (width) between the side wall 37A and the inclined wall 37D is larger than W1. Thereby, when the web 12A is fitted (inserted) into the cut portion 37, the web 12A and the cut portion 37 are prevented from contacting each other.

また、第４支持プレート３５では、第４支持プレート３５の下端から傾斜壁３７Ｄの上端までの高さｈ１よりも、第４支持プレート３５の下端から側壁３７Ａの上端までの高さｈ２の方が高くなっている。即ち、側壁３７Ａの高さは、側壁３７Ｃの高さよりも高くなっており、側壁３７Ａの面にウェブ１２Ａの側面を接触させることで、アーチ部材１２が位置決めされるようになっている。 In the fourth support plate 35, the height h2 from the lower end of the fourth support plate 35 to the upper end of the side wall 37A is higher than the height h1 from the lower end of the fourth support plate 35 to the upper end of the inclined wall 37D. It is high. That is, the height of the side wall 37A is higher than the height of the side wall 37C, and the arch member 12 is positioned by bringing the side surface of the web 12A into contact with the surface of the side wall 37A.

図３（Ｂ）に示すように、第４支持プレート３５の下端から最高点までの高さと、第４支持プレート３６の下端から最高点までの高さは、いずれもｈ２で揃えられている。このように、高さが揃えられている第４支持プレート３５、３６は、アーチ部材１２がほぼ水平配置される箇所に用いられる。 As shown in FIG. 3B, the height from the lower end of the fourth support plate 35 to the highest point and the height from the lower end of the fourth support plate 36 to the highest point are all aligned at h2. Thus, the 4th support plates 35 and 36 with which height is equalized are used in the location where the arch member 12 is arrange | positioned substantially horizontally.

一方、アーチ部材１２又は斜材１４（図２参照）が水平方向に対して傾斜配置される箇所では、図３（Ｃ）に示すように、第４支持プレート３５に換えて、第４支持プレート３９が用いられる。第４支持プレート３９は、下端から最高点までの高さがｈ３（＞ｈ２）となっており、第４支持プレート３９の切込部３７の高さ位置の方が、第４支持プレート３６の切込部３８の高さ位置よりも高くなっている。これにより、切込部３７、３８に合せてアーチ部材１２又は斜材１４（図２参照）を配置することで、アーチ部材１２又は斜材１４が傾斜配置される。 On the other hand, in the place where the arch member 12 or the diagonal member 14 (see FIG. 2) is inclined with respect to the horizontal direction, the fourth support plate 35 is replaced with the fourth support plate 35 as shown in FIG. 39 is used. The height from the lower end to the highest point of the fourth support plate 39 is h3 (> h2), and the height position of the cut portion 37 of the fourth support plate 39 is higher than that of the fourth support plate 36. The height of the cut portion 38 is higher. Thereby, the arch member 12 or the diagonal member 14 (see FIG. 2) is arranged in accordance with the notches 37 and 38, so that the arch member 12 or the diagonal member 14 is inclined.

なお、第４支持プレート３５、３６、３９における各高さｈ１、ｈ２、ｈ３は、配置するアーチ部材１２又は斜材１４の傾斜角度（設計値）に基づいて設定されている。また、図３（Ｃ）において、アーチ部材１２又は斜材１４（図２参照）の傾斜方向が逆になる場所では、第４支持プレート３６と第４支持プレート３９を入れ換えて配置する。 The heights h1, h2, and h3 of the fourth support plates 35, 36, and 39 are set based on the inclination angle (design value) of the arch member 12 or the diagonal member 14 to be arranged. Further, in FIG. 3C, the fourth support plate 36 and the fourth support plate 39 are interchanged and arranged in a place where the inclination direction of the arch member 12 or the diagonal member 14 (see FIG. 2) is reversed.

It is supported by the support plate 36. Since the fourth support plate 35 side is the same as the fourth support plate 36 side, description thereof is omitted.

続いて、図８（Ｂ）に示すように、ウェブ１２Ａと側壁３８Ｃとの隙間に三角柱状の楔材５２を打ち込む。これにより、ウェブ１２Ａの一方の側面が側壁３８Ａと接触し、アーチ部材１２が位置決めされる。即ち、アーチ部材１２は、下方向及びウェブ１２Ａの幅方向への移動が第４支持プレート３６により規制されると共に、ウェブ１２Ａの軸方向への移動が楔材５２により規制されることで、三方向の移動が規制されて位置決めされる。 Subsequently, as shown in FIG. 8B, a triangular prism wedge material 52 is driven into the gap between the web 12A and the side wall 38C. Thereby, one side surface of the web 12A comes into contact with the side wall 38A, and the arch member 12 is positioned. In other words, the arch member 12 is restricted by the fourth support plate 36 from moving in the downward direction and the width direction of the web 12A, and the movement of the web 12A in the axial direction is restricted by the wedge material 52. Positional movement is restricted.

続いて、図７（Ｂ）に示すように、同様の手順で支保装置２０により複数のアーチ部材１２を位置決めした後、各アーチ部材１２の両端部を接続ブラケット４８、４９にボルト及びナット（図示省略）で締結することで、フレーム材４６、４７に複数のアーチ部材１２を取り付ける。これにより、複数のアーチ部材１２が間隔をあけて配置される。 Subsequently, as shown in FIG. 7B, after the plurality of arch members 12 are positioned by the support device 20 in the same procedure, both ends of each arch member 12 are connected to connection brackets 48 and 49 with bolts and nuts (illustrated). The plurality of arch members 12 are attached to the frame members 46 and 47 by fastening with (omitted). Thereby, the some arch member 12 is arrange | positioned at intervals.

続いて、図１に示すように、各アーチ部材１２に複数の斜材１４及び鉄骨材１５の両端部を接続することで、構造物１０の鉄骨部分が構築される。そして、一例として、複数のアーチ部材１２及び斜材１４上にアルミフレーム及びガラス（図示省略）が取り付けられ、構造物１０（屋根）が出来上がる。 Then, as shown in FIG. 1, the steel frame part of the structure 10 is constructed | assembled by connecting the both ends of the several diagonal material 14 and the steel frame material 15 to each arch member 12. As shown in FIG. And as an example, an aluminum frame and glass (illustration omitted) are attached on the some arch member 12 and the diagonal member 14, and the structure 10 (roof) is completed.

（支保装置の分解）
構造物１０の完成後、楔材５２（図８（Ｂ）参照）を抜いてパイプサポート２１の高さを低くする。そして、図４（Ｆ）、（Ｅ）、（Ｄ）に示す順で第４支持プレート３５、３６、（３９含む）を取り外すと共に、第３支持プレート３２、３４を大引３０から取り外す。さらに、図４（Ｃ）に示すように、クレーン（図示省略）により大引３０を吊り上げることにより、大引３０を第２支持プレート２７、２８から取り外す。なお、大引３０に第３支持プレート３２、３４、及び第４支持プレート３５、３６、３９が設けられたまま大引３０を取り外してもよい。 (Disassembly of support device)
After the structure 10 is completed, the wedge material 52 (see FIG. 8B) is pulled out, and the height of the pipe support 21 is lowered. Then, the fourth support plates 35, 36, (including 39) are removed in the order shown in FIGS. 4F, 4E, and 4D, and the third support plates 32, 34 are removed from the large pull 30. Furthermore, as shown in FIG. 4C, the large pull 30 is removed from the second support plates 27 and 28 by lifting the large pull 30 with a crane (not shown). Note that the large pull 30 may be removed while the third support plates 32 and 34 and the fourth support plates 35, 36 and 39 are provided on the large pull 30.

続いて、図４（Ｂ）、（Ａ）に示す順で第２支持プレート２７、２８を取り外すと共に、第１支持プレート２５、２６を受板２４から取り外す。そして、パイプサポート２１を回収することで、支保装置２０（図１参照）が撤去される。なお、第１支持プレート２５、２６及び第２支持プレート２７、２８の取り外しは、大引３０を取り外した直後でなくともよく、パイプサポート２１を回収した後でもよい。 Subsequently, the second support plates 27 and 28 are removed in the order shown in FIGS. 4B and 4A, and the first support plates 25 and 26 are removed from the receiving plate 24. Then, by collecting the pipe support 21, the support device 20 (see FIG. 1) is removed. The removal of the first support plates 25 and 26 and the second support plates 27 and 28 may not be performed immediately after removing the large pull 30 but may be performed after the pipe support 21 is recovered.

以上説明したように、第１実施形態の支保装置２０によれば、第４支持プレート３５、３６の切込部３７、３８にアーチ部材１２、斜材１４（架構材等）を嵌めると、アーチ部材１２、斜材１４をずらさずに支持できる。このため、アーチ部材１２、斜材１４を効率よく保持できる。 As described above, according to the support device 20 of the first embodiment, when the arch member 12 and the diagonal member 14 (framework material, etc.) are fitted into the notches 37, 38 of the fourth support plates 35, 36, the arch The member 12 and the diagonal member 14 can be supported without shifting. For this reason, the arch member 12 and the diagonal member 14 can be efficiently held.

また、大引３０が複数のパイプサポート２１に跨って架設されており、大引３０の軸方向両端部の位置（高さ）を合わせるだけで大引３０の軸方向中央部の位置（高さ）が合うので、各第４支持プレート３５、３６の座標位置合せが容易になる。これにより、隣接するアーチ部材１２、斜材１４の間隔を正確に保持できる。さらに、大引３０で複数のパイプサポート２１が連結されるため、支保全体（複数の支保装置２０）の剛性が高くなる。 In addition, the large pull 30 is extended over the plurality of pipe supports 21, and the position (height) of the central portion in the axial direction of the large pull 30 is obtained only by matching the positions (heights) of both ends in the axial direction of the large pull 30. ), The coordinate alignment of the fourth support plates 35 and 36 is facilitated. Thereby, the space | interval of the adjacent arch member 12 and the diagonal 14 can be hold | maintained correctly. Further, since the plurality of pipe supports 21 are connected by the large pull 30, the rigidity of the support body (the plurality of support devices 20) is increased.

加えて、第１実施形態の支保装置２０によれば、大引３０が水平方向に対して傾斜配置されることで、第４支持プレート３５、３６、３９が大引３０の傾斜に応じた高さ位置となる。これにより、アーチ部材１２及び斜材１４を含む構造部材が不整形な部材（各部位の高さが違う部材）であっても、別途、高さ位置を調整する補助部材を設けずに構造部材を的確に保持できる。 In addition, according to the support device 20 of the first embodiment, the fourth support plates 35, 36, and 39 are arranged according to the inclination of the large pull 30 by arranging the large pull 30 to be inclined with respect to the horizontal direction. Position. Thereby, even if the structural member including the arch member 12 and the diagonal member 14 is an irregularly shaped member (a member having a different height of each part), the structural member is separately provided without an auxiliary member for adjusting the height position. Can be accurately maintained.

また、第１実施形態の支保装置２０によれば、不整形で複雑なアーチ部材１２、斜材１４の部位毎の傾きに応じて第２支持プレート２７、２８の形状を決めることで、大引３０を的確な傾斜で保持できると共にアーチ部材１２、斜材１４を的確に保持できる。さらに、第４支持プレート３５、３６を第３支持プレート３２、３４と交差するように差し込むことで立設させているので、第４支持プレート３５、３６の強度を高めることができる。そして、第４支持プレート３５、３６を第３支持プレート３２、３４に差し込むだけで組み立てられるので、支保装置２０の組立、分解が容易となる。 In addition, according to the support device 20 of the first embodiment, the shape of the second support plates 27 and 28 is determined according to the inclination of each part of the arch member 12 and the diagonal member 14 which are irregular and complicated, so that 30 can be held with an appropriate inclination, and the arch member 12 and the diagonal member 14 can be accurately held. Further, since the fourth support plates 35 and 36 are erected by being inserted so as to intersect the third support plates 32 and 34, the strength of the fourth support plates 35 and 36 can be increased. And since it assembles only by inserting the 4th support plates 35 and 36 in the 3rd support plates 32 and 34, assembly and disassembly of support device 20 become easy.

加えて、第１実施形態の支保装置２０による支保工法によれば、第１支持プレート２５、２６、第２支持プレート２７、２８、第３支持プレート３２、３４、及び第４支持プレート３５、３６が地組みされる。これにより、作業し難い高所での作業時間が減るので、支保装置２０の設置を短時間で行うことができる。 In addition, according to the support method using the support device 20 of the first embodiment, the first support plates 25 and 26, the second support plates 27 and 28, the third support plates 32 and 34, and the fourth support plates 35 and 36 are used. Is grounded. Thereby, since the working time at a high place where it is difficult to work is reduced, the support device 20 can be installed in a short time.
