以上のように構成される補強用棒状部材配置用補助具81を用いて、中空柱100を補強する補強工法について図9乃至図27を参照しながら作業順に説明する。   A reinforcing method for reinforcing the hollow column 100 using the reinforcing bar-shaped member arranging auxiliary tool 81 configured as described above will be described in the order of work with reference to FIGS. 9 to 27.

まず最初に、まだ補強されてなく、内部に何も入っていない中空柱100の中に対しては、まずガイド棒23が側部開口100aから中空柱100内に挿入される。図14は、ガイド棒23以外にその他の部材も中空柱100内にある状態を示しているが、ガイド棒23は、この図14に示すように、中空柱100の底から側部開口100aの真横まで真っすぐ垂直に伸びているものであり、その上端は側部開口100aの真横に設定される。なお、このガイド棒23の下端には、ガイド棒固定用冶具27が取り付けられていて、このガイド棒固定用冶具27によりガイド棒23を中空柱100の中心軸に設定するようになっている。   First, the guide rod 23 is first inserted into the hollow column 100 from the side opening 100a into the hollow column 100 which has not been reinforced and has nothing inside. FIG. 14 shows a state in which other members other than the guide rod 23 are also in the hollow column 100. However, as shown in FIG. 14, the guide rod 23 extends from the bottom of the hollow column 100 to the side opening 100a. It extends straight up to the side, and its upper end is set to the side of the side opening 100a. A guide rod fixing jig 27 is attached to the lower end of the guide rod 23, and the guide rod 23 is set to the central axis of the hollow column 100 by the guide rod fixing jig 27.

このようにガイド棒23が中空柱100内に挿入された状態において、次に図6に示すように、補強用棒状部材配置用補助具81の固定部材84を中空柱100の側部開口100aに対向する奥側の内壁100bにドライバー300によりねじ86で取り付ける。それから、この内壁100bに取り付けられた固定部材84の載置部84cに対して、図2に示すように、ロッド挿入補助部材83およびPC挿入補助部材82を重ねて載置し、その上から挿入補助部材貫通押え部材85の棒状部材85aをロッド挿入補助部材83およびPC挿入補助部材82のそれぞれの中心孔83a、82aおよび載置部84cの開口部に挿入し、その上に押え部85bを載せて、ロッド挿入補助部材83とPC挿入補助部材82を押え部85bで上から押さえつけ、図1に示すように、ロッド挿入補助部材83およびPC挿入補助部材82を固定部材84の載置部84cの上に載置する。   In the state where the guide rod 23 is inserted into the hollow column 100 in this way, the fixing member 84 of the reinforcing rod-shaped member arranging auxiliary tool 81 is inserted into the side opening 100a of the hollow column 100 as shown in FIG. It attaches with the screw | thread 86 with the driver 300 to the opposing inner wall 100b. Then, as shown in FIG. 2, the rod insertion auxiliary member 83 and the PC insertion auxiliary member 82 are placed on top of each other on the placement portion 84c of the fixing member 84 attached to the inner wall 100b, and inserted from above. The rod-like member 85a of the auxiliary member penetrating pressing member 85 is inserted into the center holes 83a and 82a and the opening portions of the mounting portion 84c of the rod insertion auxiliary member 83 and the PC insertion auxiliary member 82, and the pressing portion 85b is placed thereon. Then, the rod insertion assisting member 83 and the PC insertion assisting member 82 are pressed from above by the presser portion 85b, and the rod insertion assisting member 83 and the PC insertion assisting member 82 are attached to the mounting portion 84c of the fixing member 84 as shown in FIG.

それから、図18に示す第1のロッド配置用スペーサ71を図28に示すように垂直に立てながら側部開口100aから中空柱100内に挿入し、中空柱100内で水平にする。なお、この第1のロッド配置用スペーサ71は、中空柱100内に挿入される複数の第1のロッド配置用スペーサ71のうちの最初、すなわち1番目の第1のロッド配置用スペーサ71である。   Then, the first rod arrangement spacer 71 shown in FIG. 18 is inserted into the hollow column 100 from the side opening 100a while standing vertically as shown in FIG. The first rod arrangement spacer 71 is the first of the plurality of first rod arrangement spacers 71 inserted into the hollow column 100, that is, the first first rod arrangement spacer 71. .

なお、第1のロッド配置用スペーサ71は、図18に示すように補強用リング73が周囲に取り付けられているものであるが、この補強用リング73がないものが図19に示す第2のロッド配置用スペーサ75であり、両者の補強用リング73を除いた内部構造は、同じであり、アラミドロッドおよびPC鋼線からなる複数の補強用棒状部材を挿通して保持する保持部である複数のアラミドロッド保持部71cおよびPC鋼線保持部71eを有する。   As shown in FIG. 18, the first rod arrangement spacer 71 has a reinforcing ring 73 attached to the periphery, but the one without the reinforcing ring 73 is the second rod shown in FIG. The rod arrangement spacer 75 has the same internal structure excluding the reinforcing ring 73, and a plurality of holding portions that are inserted and held by a plurality of reinforcing rod-shaped members made of an aramid rod and a PC steel wire. The aramid rod holding part 71c and the PC steel wire holding part 71e are provided.

更に詳しくは、第1、第2のロッド配置用スペーサ71、75は、中心部にガイド棒23が挿通される中心孔71aが形成され、この中心孔71aから四方に放射状に等角度で均等に延出する複数の連結部71bの先端には、補強用棒状部材であるアラミドロッドが挿通されて保持されるリング状のアラミドロッド保持部71cが複数(本実施形態では6個)形成されている。また、この複数のアラミドロッド保持部71cは、隣接するもの同士がリンク71dで環状に連結され、このリンク71dの中間には別の補強用棒状部材であるPC鋼線が挿通されて保持されるリング状の小径のPC鋼線保持部71eが複数(本実施形態では6個)形成されている。   More specifically, the first and second rod arrangement spacers 71 and 75 have a central hole 71a through which the guide rod 23 is inserted at the center, and are evenly equidistant from the central hole 71a in a radial direction. A plurality (six in this embodiment) of ring-shaped aramid rod holding portions 71c that are inserted and held by aramid rods that are reinforcing rod-shaped members are formed at the ends of the plurality of extending connecting portions 71b. . In addition, adjacent ones of the plurality of aramid rod holding portions 71c are connected in a ring shape by a link 71d, and a PC steel wire that is another reinforcing rod-like member is inserted and held in the middle of the link 71d. A plurality of ring-shaped small-diameter PC steel wire holding portions 71e (six in this embodiment) are formed.

なお、上述したように構成される第1、第2のロッド配置用スペーサ71、75の複数のアラミドロッド保持部71cおよびPC鋼線保持部71eは、補強用リング73の周方向において、ひいては中空柱100の周方向において等角度で均等に形成されているとともに、複数のアラミドロッド保持部71cとPC鋼線保持部71eは、中空柱の周方向に交互に配設されている。   The plurality of aramid rod holding portions 71c and the PC steel wire holding portions 71e of the first and second rod arrangement spacers 71 and 75 configured as described above are eventually hollow in the circumferential direction of the reinforcing ring 73. A plurality of aramid rod holding portions 71c and PC steel wire holding portions 71e are alternately arranged in the circumferential direction of the hollow column while being equally formed at an equal angle in the circumferential direction of the column 100.

このように構成される第1、第2のロッド配置用スペーサ71、75は、上述したように、中空柱100内に水平に入れられ、それぞれの複数のアラミドロッド保持部71cおよびPC鋼線保持部71eに補強用棒状部材であるアラミドロッドおよびPC鋼線が複数挿通され、これらのアラミドロッドおよびPC鋼線を保持し、これによりアラミドロッドおよびPC鋼線を中空柱100の周方向において等角度で均等に配設するようになっている。   As described above, the first and second rod arrangement spacers 71 and 75 configured as described above are horizontally placed in the hollow column 100, and each of the plurality of aramid rod holding portions 71c and the PC steel wire is held. A plurality of aramid rods and PC steel wires, which are reinforcing rod-shaped members, are inserted into the portion 71e, and these aramid rods and PC steel wires are held, whereby the aramid rods and PC steel wires are equiangular in the circumferential direction of the hollow column 100. Are arranged evenly.

すなわち、上述したように側部開口100aから挿入され中空柱100内で水平にされた第1のロッド配置用スペーサ71の中心孔71aにガイド棒23の上端が図17(a)に示すように挿入され、このガイド棒23の上端に設けられているスペーサ配置用補助具37の上に第1のロッド配置用スペーサ71を載せる。それから、この第1のロッド配置用スペーサ71の2箇所のアラミドロッド保持部71cに対して2本の案内管1の上端を挿入する。すなわち、図17(b)に示すように、第1のロッド配置用スペーサ71の複数のアラミドロッド保持部71cのうち、対角にある、すなわち距離をあけて対向する2箇所のアラミドロッド保持部71cに2本の案内管1の上端を挿入する。   That is, as described above, the upper end of the guide rod 23 is inserted into the central hole 71a of the first rod arrangement spacer 71 inserted through the side opening 100a and leveled in the hollow column 100 as shown in FIG. The first rod arrangement spacer 71 is placed on the spacer arrangement auxiliary tool 37 inserted and provided at the upper end of the guide rod 23. Then, the upper ends of the two guide tubes 1 are inserted into the two aramid rod holding portions 71 c of the first rod arrangement spacer 71. That is, as shown in FIG. 17 (b), two aramid rod holding portions that are diagonal, that is, facing each other at a distance, out of the plurality of aramid rod holding portions 71 c of the first rod arrangement spacer 71. The upper ends of the two guide tubes 1 are inserted into 71c.

なお、前記第1のロッド配置用スペーサ71の中空柱100内への挿入においては、前記スペーサ配置用補助具31に取り付けられたステンレスワイヤ33を第1のロッド配置用スペーサ71の中心孔71aに近い開口部を貫通させてから第1のロッド配置用スペーサ71を中空柱100内に挿入する。このようにステンレスワイヤ33を設定することにより、ステンレスワイヤ33を中空柱100の外部で引き上げたり、引き下げたりした場合、このステンレスワイヤ33でスペーサ配置用補助具31を円滑に引き上げたり、引き下げたりでき、ひいてはスペーサ配置用補助具31上に載せられた第1のロッド配置用スペーサ71を同様に円滑に引き上げたり、引き下げることができる。   When inserting the first rod arrangement spacer 71 into the hollow column 100, the stainless wire 33 attached to the spacer arrangement auxiliary tool 31 is inserted into the central hole 71a of the first rod arrangement spacer 71. The first rod arrangement spacer 71 is inserted into the hollow column 100 after passing through the close opening. By setting the stainless steel wire 33 in this way, when the stainless steel wire 33 is pulled up or pulled down outside the hollow column 100, the spacer arranging auxiliary tool 31 can be smoothly pulled up or pulled down by the stainless steel wire 33. As a result, the first rod arrangement spacer 71 placed on the spacer arrangement auxiliary tool 31 can be smoothly raised or lowered similarly.

また、前記2本の案内管1の挿入においては、図17(a)において矢印200で示すように、案内管1を上方に引き上げ、この引き上げられた案内管1の上端を第1のロッド配置用スペーサ71のアラミドロッド保持部71cに挿入し、この状態で案内管1が中空柱100の底から浮いていることを確認してから、案内管1をピンで第1のロッド配置用スペーサ71に固定する。   Further, in the insertion of the two guide tubes 1, as indicated by an arrow 200 in FIG. 17A, the guide tube 1 is pulled upward, and the upper end of the pulled guide tube 1 is disposed in the first rod arrangement. After inserting the guide tube 1 into the aramid rod holding portion 71c of the spacer 71 and confirming that the guide tube 1 is floating from the bottom of the hollow column 100 in this state, the guide tube 1 is pinned with the first rod arrangement spacer 71. Secure to.

次に、スペーサ配置用補助具35のいもねじを緩めて、フリーにしてから、スペーサ配置用補助具31のステンレスワイヤ33を緩め、図20において矢印201で示すように、例えば10cm程度、第1のロッド配置用スペーサ71をスペーサ配置用補助具31、スペーサ配置用補助具35、スペーサ配置用補助具37とともに下降させる。また、第1のロッド配置用スペーサ71を下降させたら、案内管1を固定していたピンを引き抜き、図20において矢印202で示すように下降させる。   Next, after loosening the potato screw of the spacer arranging auxiliary tool 35 to make it free, the stainless steel wire 33 of the spacer arranging auxiliary tool 31 is loosened, and as shown by an arrow 201 in FIG. The rod arranging spacer 71 is moved down together with the spacer arranging auxiliary tool 31, the spacer arranging auxiliary tool 35, and the spacer arranging auxiliary tool 37. When the first rod arrangement spacer 71 is lowered, the pin that has fixed the guide tube 1 is pulled out and lowered as indicated by an arrow 202 in FIG.

それから、スペーサ固定用パイプ39を側部開口100aから中空柱100内に挿入し、このスペーサ固定用パイプ39を図20に示すようにガイド棒23の上端に挿入し、第1のロッド配置用スペーサ71の上に配設する。なお、このスペーサ固定用パイプ39は、今回の1番目の第1のロッド配置用スペーサ71と次の2番目の第1のロッド配置用スペーサ71との間に間隔を設けるためのものであり、その長さは、例えば13cm程度である。   Then, the spacer fixing pipe 39 is inserted into the hollow column 100 from the side opening 100a, and the spacer fixing pipe 39 is inserted into the upper end of the guide rod 23 as shown in FIG. 71 is disposed on 71. The spacer fixing pipe 39 is used to provide a space between the first first rod arrangement spacer 71 and the next second rod arrangement spacer 71. The length is, for example, about 13 cm.

このようにスペーサ固定用パイプ39をガイド棒23の上端に挿入したら、次に上述した1番目の第1のロッド配置用スペーサ71と同様に、2番目の第1のロッド配置用スペーサ71を側部開口100aから垂直に立てるようにして中空柱100内に挿入してから水平にし、この水平にされた2番目の第1のロッド配置用スペーサ71の中心孔71aにガイド棒23の上端を挿入し、このガイド棒23の上端に設けられているスペーサ固定用パイプ39の上に載せる。それから、この2番の第1のロッド配置用スペーサ71の2箇所のアラミドロッド保持部71cに対して2本の案内管1の上端を同様に、すなわち第1のロッド配置用スペーサ71の複数のアラミドロッド保持部71cのうち、対角にある2箇所のアラミドロッド保持部71cに案内管1の上端を挿入する。   When the spacer fixing pipe 39 is inserted into the upper end of the guide rod 23 in this way, the second first rod arrangement spacer 71 is moved to the side in the same manner as the first first rod arrangement spacer 71 described above. Inserted into the hollow column 100 so as to stand upright from the opening 100a and then horizontal, and the upper end of the guide rod 23 is inserted into the center hole 71a of the horizontal first rod arranging spacer 71. Then, it is placed on the spacer fixing pipe 39 provided at the upper end of the guide rod 23. Then, the upper ends of the two guide tubes 1 are similarly arranged with respect to the two aramid rod holding portions 71c of the second first rod arrangement spacer 71, that is, a plurality of first rod arrangement spacers 71 are arranged. The upper end of the guide tube 1 is inserted into two diagonal aramid rod holding portions 71c of the aramid rod holding portion 71c.

更に、同様に、2番目のスペーサ固定用パイプ39を側部開口100aから中空柱100内に挿入し、このスペーサ固定用パイプ39をガイド棒23の上端に挿入し、この上に更に3番目の第1のロッド配置用スペーサ71を挿入するという処理を13番目の第1のロッド配置用スペーサ71まで繰り返し行う。   Further, similarly, the second spacer fixing pipe 39 is inserted into the hollow column 100 from the side opening 100a, and this spacer fixing pipe 39 is inserted into the upper end of the guide rod 23. The process of inserting the first rod arrangement spacer 71 is repeated up to the thirteenth first rod arrangement spacer 71.

なお、上述した複数の第1のロッド配置用スペーサ71の挿入においては、各第1のロッド配置用スペーサ71を挿入する毎に、スペーサ配置用補助具31に取り付けられたステンレスワイヤ33を各第1のロッド配置用スペーサ71の中心孔71aに近い対応する開口部を貫通させてから第1のロッド配置用スペーサ71を中空柱100内に挿入する。このとき、ステンレスワイヤ33を貫通させる第1のロッド配置用スペーサ71の中心孔71aに近い開口部がすべての第1のロッド配置用スペーサ71において同じ位置となり、ステンレスワイヤ33がほぼ真っすぐになるように、すなわちジグザグになったり、曲がらないように各開口部を貫通することが必要である。   In the insertion of the plurality of first rod arrangement spacers 71 described above, each time the first rod arrangement spacer 71 is inserted, the stainless wire 33 attached to the spacer arrangement auxiliary tool 31 is attached to each of the first rod arrangement spacers 71. The first rod arrangement spacer 71 is inserted into the hollow column 100 after passing through a corresponding opening close to the center hole 71 a of the first rod arrangement spacer 71. At this time, the opening close to the center hole 71a of the first rod arrangement spacer 71 through which the stainless wire 33 passes is the same position in all the first rod arrangement spacers 71, so that the stainless wire 33 is almost straight. In other words, it is necessary to penetrate each opening so as not to be zigzag or bend.

そして、このようにステンレスワイヤ33を真っすぐ貫通させることにより、ステンレスワイヤ33を中空柱100の外部で引き上げたり、引き下げたりした場合、このステンレスワイヤ33でスペーサ配置用補助具31を介して第1のロッド配置用スペーサ71をすべて同様に円滑に引き上げたり、引き下げることができる。   When the stainless steel wire 33 is pulled up or pulled down from the hollow column 100 by passing through the stainless steel wire 33 in this manner, the stainless steel wire 33 is used to pass the first via the spacer placement aid 31. The rod arrangement spacers 71 can all be raised and lowered smoothly in a similar manner.

図21は、上述したように13個の第1のロッド配置用スペーサ71を挿入した状態を示している。このように13個の第1のロッド配置用スペーサ71のそれぞれの対角にある2箇所のアラミドロッド保持部71cに2本の案内管1を挿入することにより、この13個の第1のロッド配置用スペーサ71は、それぞれの各アラミドロッド保持部71cが中空柱100の周方向の同じ位置に整列することになる。   FIG. 21 shows a state in which 13 first rod arrangement spacers 71 are inserted as described above. Thus, by inserting the two guide tubes 1 into the two aramid rod holding portions 71c at the diagonal positions of the thirteen first rod arrangement spacers 71, the thirteen first rods In the arrangement spacer 71, the respective aramid rod holding portions 71 c are aligned at the same position in the circumferential direction of the hollow column 100.

このように13個の第1のロッド配置用スペーサ71を挿入した後は、次に上述したと同様に、図21で一番上にある13個目の第1のロッド配置用スペーサ71の上から、ガイド棒23の上端にスペーサ固定用パイプ39を挿入し、それから更に図19に示す補強用リング73のない第2のロッド配置用スペーサ75を側部開口100aから中空柱100内に挿入する。そして、この第2のロッド配置用スペーサ75に対して上述した第1のロッド配置用スペーサ71と同様に、その中心孔71aにガイド棒23の上端を挿入し、ガイド棒23の上端のスペーサ固定用パイプ39の上に配設するとともに、上述と同様に、第2のロッド配置用スペーサ75の対角にある2箇所のアラミドロッド保持部71cに前記2本の案内管1を挿入し固定する。この状態が図22(a)に示す状態であり、また2本の案内管1が第2のロッド配置用スペーサ75のアラミドロッド保持部71cに挿入された第2のロッド配置用スペーサ75の状態が図22(b)に示されている。なお、この挿入された第2のロッド配置用スペーサ75は、1番目の第2のロッド配置用スペーサ75である。   After the thirteen first rod arrangement spacers 71 have been inserted in this manner, the top of the thirteenth first rod arrangement spacer 71 at the top in FIG. Then, the spacer fixing pipe 39 is inserted into the upper end of the guide rod 23, and then the second rod arrangement spacer 75 without the reinforcing ring 73 shown in FIG. 19 is inserted into the hollow column 100 from the side opening 100a. . Then, the upper end of the guide rod 23 is inserted into the center hole 71a in the same way as the first rod arrangement spacer 71 described above with respect to the second rod arrangement spacer 75, and the upper end of the guide rod 23 is fixed to the spacer. As described above, the two guide tubes 1 are inserted into and fixed to the two aramid rod holding portions 71c at the opposite corners of the second rod arrangement spacer 75 in the same manner as described above. . This state is the state shown in FIG. 22A, and the state of the second rod arrangement spacer 75 in which the two guide tubes 1 are inserted into the aramid rod holding portion 71 c of the second rod arrangement spacer 75. Is shown in FIG. The inserted second rod arrangement spacer 75 is the first second rod arrangement spacer 75.

この1番目の第2のロッド配置用スペーサ75の挿入においても、前記第1のロッド配置用スペーサ71の場合と同様に、スペーサ配置用補助具31に取り付けられたステンレスワイヤ33をこの1番目の第2のロッド配置用スペーサ75の中心孔71aに近い開口部を貫通させてから第2のロッド配置用スペーサ75を中空柱100内に挿入することは同じである。   Also in the insertion of the first second rod arrangement spacer 75, the stainless wire 33 attached to the spacer arrangement auxiliary tool 31 is attached to the first rod arrangement spacer 71 in the same manner as in the case of the first rod arrangement spacer 71. It is the same that the second rod arrangement spacer 75 is inserted into the hollow column 100 after passing through the opening near the center hole 71a of the second rod arrangement spacer 75.

次に、前記スペーサ固定用パイプ39よりも短めの、例えば長さ10cm程度のガイド棒連結パイプ65を側部開口100aから挿入し、前記1番目の第2のロッド配置用スペーサ75の上の、ガイド棒23の上端に挿入し、高ナットで固定する。なお、このガイド棒連結パイプ65が挿入された状態は、図23に示されているが、この図23では、ガイド棒連結パイプ65の上には次に説明する2番目の第2のロッド配置用スペーサ75が既に挿入された状態で示されている。   Next, a guide rod connecting pipe 65 that is shorter than the spacer fixing pipe 39, for example, about 10 cm in length, is inserted from the side opening 100a, and above the first second rod arrangement spacer 75, It is inserted into the upper end of the guide bar 23 and fixed with a high nut. The state where the guide rod connecting pipe 65 is inserted is shown in FIG. 23. In FIG. 23, the second rod arrangement described below is arranged on the guide rod connecting pipe 65. The spacer 75 for use is already inserted.

すなわち、次に、2番目の第2のロッド配置用スペーサ75を側部開口100aから中空柱100内に挿入し、この2番目の第2のロッド配置用スペーサ75の中心孔71aにガイド棒連結パイプ65の上に突出しているガイド棒23の上端を図23に示すように挿入するとともに、上述と同様に、この2番目の第2のロッド配置用スペーサ75の対角にある2箇所のアラミドロッド保持部71cに前記2本の案内管1を挿入し固定する。このように13個の第1のロッド配置用スペーサ71に続いて、2個の第2のロッド配置用スペーサ75を挿入し、この2個の第2のロッド配置用スペーサ75のアラミドロッド保持部71cにも2本の案内管1を挿入することにより、上述したように、13個の第1のロッド配置用スペーサ71のみならず、2個の第2のロッド配置用スペーサ75のそれぞれの各アラミドロッド保持部71cも第1のロッド配置用スペーサ71に続いて中空柱100の周方向の同じ位置に整列することになる。なお、この2番目の第2のロッド配置用スペーサ75には、前記スペーサ配置用補助具31に取り付けられているステンレスワイヤ33は通さない。   That is, next, the second second rod arrangement spacer 75 is inserted into the hollow column 100 from the side opening 100a, and the guide rod is connected to the center hole 71a of the second second rod arrangement spacer 75. The upper end of the guide rod 23 protruding above the pipe 65 is inserted as shown in FIG. 23, and two aramids at the opposite corners of the second second rod arrangement spacer 75 are inserted as described above. The two guide tubes 1 are inserted and fixed to the rod holding portion 71c. Thus, following the 13 first rod arrangement spacers 71, the two second rod arrangement spacers 75 are inserted, and the aramid rod holding portions of the two second rod arrangement spacers 75 are inserted. By inserting the two guide tubes 1 into the 71c as well, as described above, each of the two second rod arrangement spacers 75 as well as the 13 first rod arrangement spacers 71 is provided. The aramid rod holding portion 71 c is also aligned at the same position in the circumferential direction of the hollow column 100 following the first rod arrangement spacer 71. Note that the stainless steel wire 33 attached to the spacer arranging auxiliary tool 31 does not pass through the second second rod arranging spacer 75.

次に、上述したように、13個の第1のロッド配置用スペーサ71に続いて、2個の第2のロッド配置用スペーサ75を挿入し、これらのアラミドロッド保持部71cにも2本の案内管1を挿入して固定し終わったら、側部開口100aの補強用棒状部材配置用補助具81に保持されているアラミドロッド61を図24(a)で矢印205で示すように補強用棒状部材配置用補助具81から2本取り出し、この取り出した2本のアラミドロッド61を上述したように整列した13個の第1のロッド配置用スペーサ71および2個の第2のロッド配置用スペーサ75のすべてのアラミドロッド保持部71cに図24(a)および(b)に示すように挿入する。   Next, as described above, two second rod arrangement spacers 75 are inserted after the 13 first rod arrangement spacers 71, and two aramid rod holding portions 71c are also provided with two pieces. When the guide tube 1 is inserted and fixed, the aramid rod 61 held by the reinforcing rod-shaped member arranging auxiliary tool 81 in the side opening 100a is shaped like a reinforcing rod as shown by an arrow 205 in FIG. Two pieces are taken out from the member arranging auxiliary tool 81, and the two removed aramid rods 61 are arranged as described above, the 13 first rod arranging spacers 71 and the two second rod arranging spacers 75. As shown in FIGS. 24A and 24B, all the aramid rod holding portions 71c are inserted.

そして、この挿入した2本のアラミドロッド61が下降して、下に着いたことを確認したら、5cm程度浮かせた状態で、上から2番目の第2のロッド配置用スペーサ75で仮止めする。この2本のアラミドロッド61の挿入は、図24(b)に示すように、対角にある2箇所のアラミドロッド保持部71cに対して行う。   Then, when it is confirmed that the inserted two aramid rods 61 are lowered and are attached to the lower side, the second rod arrangement spacer 75 is temporarily fixed with the second rod arrangement spacer 75 from the top in a state of floating about 5 cm. The two aramid rods 61 are inserted into the two aramid rod holding portions 71c on the diagonal as shown in FIG.

上述したように、2本のアラミドロッド61を挿入すると、図24(a)および(b)に示すように、第1のロッド配置用スペーサ71および第2のロッド配置用スペーサ75のアラミドロッド保持部71cには、この2本のアラミドロッド61と2本の案内管1が挿入されているので、次に、図25(a)に示すように、このうちの、2本の案内管1を第1のロッド配置用スペーサ71および第2のロッド配置用スペーサ75のアラミドロッド保持部71cから引き抜くために、まず1本目の案内管1を引き抜き、補強用棒状部材配置用補助具81の空きスペースに収容し、それから2本目の案内管1をアラミドロッド保持部71cから引き抜き、この案内管1を側部開口100aから外部に撤去する。それから、上述したように、補強用棒状部材配置用補助具81の空きスペースに収納した1本目の案内管1を空きスペースから取り出し、同様に側部開口100aから外部に撤去する。   As described above, when the two aramid rods 61 are inserted, as shown in FIGS. 24A and 24B, the aramid rod holding of the first rod arrangement spacer 71 and the second rod arrangement spacer 75 is performed. Since the two aramid rods 61 and the two guide tubes 1 are inserted into the portion 71c, next, as shown in FIG. In order to pull out from the aramid rod holding portion 71c of the first rod arrangement spacer 71 and the second rod arrangement spacer 75, first, the first guide tube 1 is pulled out, and an empty space for the reinforcing rod-shaped member arrangement auxiliary tool 81 is obtained. Then, the second guide tube 1 is pulled out from the aramid rod holding portion 71c, and the guide tube 1 is removed from the side opening 100a to the outside. Then, as described above, the first guide tube 1 housed in the empty space of the reinforcing bar-shaped member arranging auxiliary tool 81 is taken out from the empty space and similarly removed from the side opening 100a to the outside.

この結果、第1のロッド配置用スペーサ71および第2のロッド配置用スペーサ75には、図25(b)に示すように、アラミドロッド61のみが対角で挿入された状態になり、この状態でも13個の第1のロッド配置用スペーサ71および2個の第2のロッド配置用スペーサ75のすべてのアラミドロッド保持部71cは同じ位置に整列されていることになる。   As a result, as shown in FIG. 25 (b), only the aramid rod 61 is diagonally inserted into the first rod arrangement spacer 71 and the second rod arrangement spacer 75, and this state However, all the aramid rod holding portions 71c of the 13 first rod arrangement spacers 71 and the two second rod arrangement spacers 75 are aligned at the same position.

次に、図26に示すように、複数(本実施形態では、6本)のPC鋼線63を第1のロッド配置用スペーサ71および第2のロッド配置用スペーサ75のPC鋼線保持部71eに挿入するために、PC鋼線63を1本づつ順次、補強用棒状部材配置用補助具81の受止保持部82cから取り出し、この取り出したPC鋼線63を上述したように整列した13個の第1のロッド配置用スペーサ71および2個の第2のロッド配置用スペーサ75のすべてのPC鋼線保持部71eに図26に示すように挿入し固定する。   Next, as shown in FIG. 26, a plurality of (six in this embodiment) PC steel wires 63 are made of PC steel wire holding portions 71e of the first rod arrangement spacer 71 and the second rod arrangement spacer 75. In order to insert the PC steel wire 63, the PC steel wires 63 are sequentially taken out from the receiving holding portion 82c of the reinforcing bar-shaped member arranging auxiliary tool 81 one by one, and the 13 PC steel wires 63 taken out are aligned as described above. As shown in FIG. 26, the first rod arrangement spacer 71 and the two second rod arrangement spacers 75 are inserted and fixed as shown in FIG.

それから、図27に示すように、残り(本実施形態では、4本)のアラミドロッド61を第1のロッド配置用スペーサ71および第2のロッド配置用スペーサ75のアラミドロッド保持部71cに挿入するために、アラミドロッド61を1本づつ順次、補強用棒状部材配置用補助具81の受止保持部83bから取り出し、この取り出したアラミドロッド61を順次、上述したように整列した13個の第1のロッド配置用スペーサ71および2個の第2のロッド配置用スペーサ75のすべてのアラミドロッド保持部71cに図27に示すように挿入し固定する。   Then, as shown in FIG. 27, the remaining (four in this embodiment) aramid rods 61 are inserted into the aramid rod holding portions 71 c of the first rod arrangement spacer 71 and the second rod arrangement spacer 75. Therefore, the aramid rods 61 are sequentially taken out one by one from the receiving holding portion 83b of the reinforcing rod-shaped member arranging auxiliary tool 81, and the taken out aramid rods 61 are sequentially arranged as described above. The rod arrangement spacers 71 and the two second rod arrangement spacers 75 are inserted and fixed in all aramid rod holding portions 71c as shown in FIG.

上述したアラミドロッド61およびPC鋼線63の挿入では、13個の第1のロッド配置用スペーサ71および2個の第2のロッド配置用スペーサ75のすべてのアラミドロッド保持部71cおよびアラミドロッド保持部71cが中空柱100の周方向の同じ位置に整列されているので、アラミドロッドおよびPC鋼線の挿入は、極めて容易となり、作業の効率化、作業時間の短縮化を図ることができることに加えて、アラミドロッド61およびPC鋼線63は、上述した作業の前に、すべて補強用棒状部材配置用補助具81の受止保持部82c、83bで保持されて、中空柱100の側部開口100aの上方に設けられているので、上方でワイヤで吊るしたり、ワイヤから取り外すなどの作業が不要となり、作業の効率化、迅速化、安全性を向上することができる。   In the insertion of the aramid rod 61 and the PC steel wire 63, all the aramid rod holding portions 71c and the aramid rod holding portions of the 13 first rod arrangement spacers 71 and the two second rod arrangement spacers 75 are used. Since the 71c is aligned at the same position in the circumferential direction of the hollow column 100, the insertion of the aramid rod and the PC steel wire becomes extremely easy, and it is possible to improve the work efficiency and the work time. The aramid rod 61 and the PC steel wire 63 are all held by the receiving holding portions 82c and 83b of the reinforcing rod-shaped member arranging auxiliary tool 81 before the above-described operation, and the side opening 100a of the hollow column 100 is formed.
