図を参照しながら、本発明の実施形態を説明する。まず、本発明の第１の実施形態について説明する。   Embodiments of the present invention will be described with reference to the drawings. First, a first embodiment of the present invention will be described.

図１（ａ）の斜視図には、継手部材内の鉄筋挿入長さ管理治具（以下、「管理治具」とする）１０が第１鉄筋１２へ取り付けられる前の状態が示され、図１（ｂ）の斜視図には、管理治具１０が第１鉄筋１２へ取り付けられた状態が示されている。   The perspective view of FIG. 1A shows a state before a reinforcing bar insertion length management jig (hereinafter referred to as “management jig”) 10 in the joint member is attached to the first reinforcing bar 12. The perspective view of 1 (b) shows a state where the management jig 10 is attached to the first rebar 12.

図２（ｅ）の側面図に示すように、管理治具１０は、第１鉄筋１２と第２鉄筋１４とが挿入された状態で連結される継手部材１６への第１鉄筋１２と第２鉄筋１４との挿入長さを規定する。第１鉄筋１２と第２鉄筋１４とは、端面を向き合わせて配置され、同径の異形鉄筋によって構成されている。継手部材１６は、第１鉄筋１２及び第２鉄筋１４を差し込むことにより挿入可能な差し込み式の機械式継手によって構成されている。   As shown in the side view of FIG.2 (e), the management jig | tool 10 is 1st rebar 12 and 2nd to the coupling member 16 connected in the state in which the 1st rebar 12 and the 2nd rebar 14 were inserted. The insertion length with the reinforcing bar 14 is defined. The 1st reinforcing bar 12 and the 2nd reinforcing bar 14 are arrange | positioned with the end surfaces facing each other, and are comprised by the deformed reinforcing bar of the same diameter. The joint member 16 is configured by a plug-in mechanical joint that can be inserted by inserting the first rebar 12 and the second rebar 14.

図１（ｂ）に示すように、管理治具１０は、基準部材としての円筒状の管部材１８と、管部材１８の材軸方向（以下、「方向Ｙ」とする）における管部材１８の端部に設けられた位置合せ部としての円筒状の照準部２０とによって構成されている。図１（ｂ）の状態で、第１鉄筋１２、第２鉄筋１４、管部材１８及び照準部２０の材軸は略一致している。   As shown in FIG. 1B, the management jig 10 includes a cylindrical tube member 18 as a reference member, and a tube member 18 in the material axis direction of the tube member 18 (hereinafter referred to as “direction Y”). It is comprised by the cylindrical aiming part 20 as an alignment part provided in the edge part. In the state of FIG. 1B, the material axes of the first reinforcing bar 12, the second reinforcing bar 14, the pipe member 18, and the aiming portion 20 are substantially aligned.

管部材１８は、鋼製であり、照準部２０は、図１（ｂ）の状態において、照準部２０の外側から照準部２０を通して第１鉄筋１２及び第２鉄筋１４の端部が目視できるように、アクリルガラス等の透明な材料によって形成されている。管部材１８と照準部２０との内径は、略等しく、第１鉄筋１２（第２鉄筋１４）の外径よりも僅かに（例えば、３ｍｍ程度）大きくなっている。   The pipe member 18 is made of steel, and the sighting portion 20 can be visually observed from the outside of the sighting portion 20 through the sighting portion 20 and the ends of the first rebar 12 and the second rebar 14 in the state of FIG. Further, it is made of a transparent material such as acrylic glass. The inner diameters of the tube member 18 and the aiming portion 20 are substantially equal, and are slightly larger (for example, about 3 mm) than the outer diameter of the first reinforcing bar 12 (second reinforcing bar 14).

図１（ａ）に示すように、管部材１８は、管部材１８を縦割りに略二等分した円弧状の外周部材２２Ａ、２２Ｂによって構成され、照準部２０は、照準部２０を縦割りに略二等分した円弧状の透明部材２４Ａ、２４Ｂによって構成されている。方向Ｙにおける外周部材２２Ａ、２２Ｂの両端部の内周面には、帯状のゴムシート２６が貼られている。   As shown in FIG. 1A, the pipe member 18 is constituted by arc-shaped outer peripheral members 22A and 22B obtained by dividing the pipe member 18 into two substantially equal parts, and the aiming part 20 vertically divides the aiming part 20. It is constituted by arcuate transparent members 24A and 24B which are substantially divided into two. On the inner peripheral surfaces of both end portions of the outer peripheral members 22A and 22B in the direction Y, a belt-like rubber sheet 26 is attached.

外周部材２２Ａ及び透明部材２４Ａと、外周部材２２Ｂ及び透明部材２４Ｂとの円周方向の一方端部同士は、ヒンジ２８によって回転可能に連結されている。これにより、第１鉄筋１２に外周部材２２Ａを添えた状態で、ヒンジ２８を回転中心にして外周部材２２Ａに対し外周部材２２Ｂを回転させ、さらに、各ゴムシート２６を第１鉄筋１２へ押し付けるようにして、外周部材２２Ａ、２２Ｂにより第１鉄筋１２を挟み込む。   One end portions in the circumferential direction of the outer peripheral member 22A and the transparent member 24A, and the outer peripheral member 22B and the transparent member 24B are rotatably connected by a hinge 28. Accordingly, the outer peripheral member 22B is rotated with respect to the outer peripheral member 22A with the hinge 28 as the rotation center in a state where the outer peripheral member 22A is attached to the first reinforcing bar 12, and each rubber sheet 26 is pressed against the first reinforcing bar 12. Thus, the first rebar 12 is sandwiched between the outer peripheral members 22A and 22B.

そして、外周部材２２Ａの円周方向の他方端部に設けられた爪部３０を、外周部材２２Ｂの円周方向の他方端部に設けられた溝部３２に引っ掛けてロックする。これにより、ゴムシート２６が第１鉄筋１２に押し付けられて密着した状態が保持され、第１鉄筋１２へ管部材１８が装着される。すなわち、第１鉄筋１２へ管理治具１０が取り付けられる。透明部材２４Ａは外周部材２２Ａと、透明部材２４Ｂは外周部材２２Ｂと一体になって動く。なお、ゴムシート２６を第１鉄筋１２へ押し付ける力は、第１鉄筋１２へ装着された状態の管部材１８を手の力で方向Ｙへ移動できるように、ゴムシート２６の厚さや材質を選定して設定する。   And the nail | claw part 30 provided in the other end part of the circumferential direction of 22 A of outer peripheral members is hooked and locked in the groove part 32 provided in the other end part of the outer peripheral member 22B in the circumferential direction. As a result, the rubber sheet 26 is pressed against the first rebar 12 and is kept in close contact, and the pipe member 18 is attached to the first rebar 12. That is, the management jig 10 is attached to the first reinforcing bar 12. The transparent member 24A moves integrally with the outer peripheral member 22A and the transparent member 24B moves together with the outer peripheral member 22B. The thickness and material of the rubber sheet 26 are selected so that the force that presses the rubber sheet 26 against the first reinforcing bar 12 can move the pipe member 18 attached to the first reinforcing bar 12 in the direction Y by hand force. And set.

管部材１８は、爪部３０を溝部３２から外しロックを解除することにより、第１鉄筋１２から取り外すことができる。すなわち、管部材１８は、第１鉄筋１２へ着脱自在に装着することができる。   The pipe member 18 can be removed from the first reinforcing bar 12 by removing the claw 30 from the groove 32 and releasing the lock. That is, the pipe member 18 can be detachably attached to the first rebar 12.

次に、管理治具１０を用いた、継手部材内の鉄筋挿入長さ管理方法について説明する。   Next, a reinforcing bar insertion length management method in the joint member using the management jig 10 will be described.

継手部材内の鉄筋挿入長さ管理方法は、図２（ａ）〜（ｅ）の側面図の順に示す、プレキャストコンクリート製の柱部材３４とプレキャストコンクリート製の梁部材３６との接合手順における、管部材装着工程及び管部材移動工程によって行われる。   The reinforcing bar insertion length management method in the joint member is a tube in the joining procedure of the column member 34 made of precast concrete and the beam member 36 made of precast concrete shown in the order of the side views of FIGS. It is performed by a member mounting process and a pipe member moving process.

まず、図２（ａ）に示すように、柱部材３４の接合面３８から突出する第２鉄筋１４に、継手部材１６をセットする（継手部材準備工程）。継手部材１６は、継手部材１６の中空部に第２鉄筋１４が挿入された状態で接合面３８側へ寄せてセットする。   First, as shown to Fig.2 (a), the coupling member 16 is set to the 2nd reinforcing bar 14 which protrudes from the joining surface 38 of the column member 34 (coupling member preparation process). The joint member 16 is set close to the joint surface 38 in a state where the second rebar 14 is inserted into the hollow portion of the joint member 16.

次に、図２（ｂ）に示すように、梁部材３６の接合面４０と、柱部材３４の接合面３８とが対向するように、梁部材３６を配置する（梁部材配置工程）。このとき、第１鉄筋１２と第２鉄筋１４とは、略水平に配置され、端面同士が隙間をあけて向き合っている。   Next, as shown in FIG. 2B, the beam member 36 is arranged so that the joint surface 40 of the beam member 36 and the joint surface 38 of the column member 34 face each other (beam member placement step). At this time, the 1st reinforcing bar 12 and the 2nd reinforcing bar 14 are arrange | positioned substantially horizontal, and end surfaces face each other with the clearance gap.

次に、第１鉄筋１２へ管部材１８を着脱自在に装着する（管部材装着工程）。
次に、図２（ｃ）に示すように、第１鉄筋１２へ装着した状態の管部材１８を方向Ｙへ移動させて、第１鉄筋１２及び第２鉄筋１４の端部に照準部２０を合せる（管部材移動工程）。すなわち、照準部２０の外側から照準部２０を通して第１鉄筋１２及び第２鉄筋１４の端部が見えるように管部材１８を移動させる。 Next, the pipe member 18 is detachably attached to the first rebar 12 (tube member attachment step).
Next, as shown in FIG. 2 (c), the tube member 18 attached to the first rebar 12 is moved in the direction Y, and the aiming portion 20 is placed at the ends of the first rebar 12 and the second rebar 14. (Pipe member moving process). That is, the pipe member 18 is moved from the outside of the aiming part 20 so that the ends of the first reinforcing bar 12 and the second reinforcing bar 14 can be seen through the aiming part 20.

次に、管部材１８を基準にして（管部材１８の端部に位置する）第１鉄筋１２又は第２鉄筋１４の部位にマジック・インキ、テープ等によってマーク４２を付ける（継手部材位置規定工程）。   Next, a mark 42 is attached to the portion of the first reinforcing bar 12 or the second reinforcing bar 14 (located at the end of the pipe member 18) with magic ink, tape or the like with reference to the pipe member 18 (joint member position defining step). ).

次に、図２（ｄ）に示すように、第１鉄筋１２から管部材１０を取り外した後、図２（ｅ）に示すように、マーク４２を基準にして（マーク４２と、継手部材１６の端部とを合わせるようにして）継手部材１６を移動させる（継手部材移動工程）。これにより、継手部材１６を所定の連結位置に配置することができる。すなわち、管部材移動工程により配置された管部材１８を基準にして継手部材１６の連結位置を規定することができ、これによって、継手部材１６への第１鉄筋１２と第２鉄筋１４との挿入長さを規定できる。   Next, as shown in FIG. 2 (d), after removing the pipe member 10 from the first reinforcing bar 12, as shown in FIG. 2 (e), the mark 42 is used as a reference (the mark 42 and the joint member 16). The joint member 16 is moved so as to match the end of the joint member (joint member moving step). Thereby, the joint member 16 can be arrange | positioned in a predetermined | prescribed connection position. In other words, the connection position of the joint member 16 can be defined with reference to the pipe member 18 arranged in the pipe member moving step, whereby the first rebar 12 and the second rebar 14 are inserted into the joint member 16. You can define the length.

最後に、接合面３８と接合面４０との間の接合部４４にコンクリートを打設し硬化させて、柱部材３４と梁部材３６との接合を完了させる（打設工程）。
なお、施工品質管理のための検査写真を撮影する場合には、例えば、図２（ｃ）、（ｅ）の状況を撮影すればよい。 Finally, concrete is cast and cured at the joint 44 between the joint surface 38 and the joint surface 40 to complete the joint between the column member 34 and the beam member 36 (placement process).
In addition, what is necessary is just to image | photograph the condition of FIG.2 (c), (e), for example, when image | photographing the inspection photograph for construction quality control.

次に、本発明の第１の実施形態の作用及び効果について説明する。   Next, the operation and effect of the first embodiment of the present invention will be described.

図２（ｃ）に示すように、第１鉄筋１２及び第２鉄筋１４の端部に照準部２０を合わせることにより継手部材１６の連結位置を規定することができ、これによって、継手部材１６への第１鉄筋１２と第２鉄筋１４との挿入長さを規定できる。
具体的には、図１（ｂ）に示すように、方向Ｙにおける管部材１８の長さをａ、方向Ｙにおける照準部２０の長さをｂ、継手部材１６に第１鉄筋１２をそれ以上挿入してしまうと継手部材１６への第２鉄筋１４の挿入長さがａよりも小さくなってしまう長さをｃ（不図示）、第１鉄筋１２の端面と第２鉄筋１４の端面との間の長さをｔとし、ａ＋ｂ＝ｃ＋ｔとなるように管理治具１０を構成すれば、管部材移動工程を行なうことによって、継手部材１６への第１鉄筋１２と第２鉄筋１４との挿入長さがａより長くなるように規定できる。 As shown in FIG. 2 (c), the connection position of the joint member 16 can be defined by aligning the aiming portion 20 with the ends of the first reinforcing bar 12 and the second reinforcing bar 14. The insertion length of the first reinforcing bar 12 and the second reinforcing bar 14 can be defined.
Specifically, as shown in FIG. 1B, the length of the tube member 18 in the direction Y is a, the length of the aiming portion 20 in the direction Y is b, and the first rebar 12 is more than the joint member 16. If inserted, the length by which the insertion length of the second rebar 14 into the joint member 16 becomes smaller than a (c) (not shown), and the end surface of the first rebar 12 and the end surface of the second rebar 14 If the management jig 10 is configured so that the length between the two is t and a + b = c + t, the first rebar 12 and the second rebar 14 are inserted into the joint member 16 by performing the pipe member moving step. The length can be defined to be longer than a.

よって、例えば、継手部材１６と第１鉄筋１２（第２鉄筋１４）との連結において必要とする連結強度を得ることが可能な、継手部材１６への第１鉄筋１２（第２鉄筋１４）の許容最小挿入長さをａとすれば、管部材移動工程を行なうことによって、第１鉄筋１２と第２鉄筋１４とが確実に連結できるように、継手部材１６への第１鉄筋１２と第２鉄筋１４との挿入長さを規定できる。
なお、これは一例であり、管部材１８及び照準部２０の方向Ｙにおける長さａ、ｂは、適宜決めればよい。例えば、先の許容最小挿入長さよりもａを長くしてもよい。 Therefore, for example, the first rebar 12 (second rebar 14) to the joint member 16 capable of obtaining the connection strength required for the connection between the joint member 16 and the first rebar 12 (second rebar 14). If the allowable minimum insertion length is a, the first rebar 12 and the second rebar 12 to the joint member 16 can be reliably connected to each other by performing the pipe member moving step. The insertion length with the reinforcing bar 14 can be defined.
This is only an example, and the lengths a and b in the direction Y of the tube member 18 and the aiming portion 20 may be determined as appropriate. For example, a may be longer than the previous allowable minimum insertion length.

また、管理治具１０は、着脱自在に第１鉄筋１２又は第２鉄筋１４へ装着される管部材１８により、第１鉄筋１２又は第２鉄筋１４へ自由に取り付けたり、取り外したりできるので、メジャーや棒状のゲージ等を鉄筋に添えて継手部材の連結位置を規定する方法に比べて、短時間で容易に継手部材の連結位置を規定することができ、一人で行うことができる。また、継手部材の連結位置を規定する作業の人為的ミスを防ぐことができる。特に、継手部材による連結箇所が多数に及ぶ建物の施工においては、多数の継手部材の連結位置を短時間で確実に規定しなければならないので、管理治具１０の使用が有効となる。   Further, the management jig 10 can be freely attached to or detached from the first reinforcing bar 12 or the second reinforcing bar 14 by a pipe member 18 that is detachably attached to the first reinforcing bar 12 or the second reinforcing bar 14, so that the measure Compared with the method of defining the coupling position of the joint member by attaching a bar-shaped gauge or the like to the reinforcing bar, the coupling position of the coupling member can be easily defined in a short time and can be performed alone. Further, it is possible to prevent human error in the work of defining the connection position of the joint member. In particular, in the construction of a building having a large number of connection points by joint members, the connection positions of the large number of joint members must be reliably defined in a short time, so that the use of the management jig 10 is effective.

また、管理治具１０を第１鉄筋１２又は第２鉄筋１４へ取り付けた状態で、施工管理記録用の検査写真を一人で撮影することができる。すなわち、継手部材１６の連結位置を規定すると同時に、写真撮影による品質検査も行なうことができる。また、複数の第１鉄筋１２又は第２鉄筋１４に管理治具１０をそれぞれ取り付けて一度に写真撮影できる。   In addition, with the management jig 10 attached to the first reinforcing bar 12 or the second reinforcing bar 14, an inspection photograph for construction management recording can be taken alone. That is, quality inspection by photography can be performed at the same time as defining the connection position of the joint member 16. Moreover, the management jig | tool 10 can be attached to the some 1st reinforcing bar 12 or the 2nd reinforcing bar 14, respectively, and photography can be carried out at once.

また、照準部２０を第１鉄筋１２及び第２鉄筋１４の端部に合せた状況と、管部材１８を基準にして第１鉄筋１２の部位にマークが付けられた状況とを目視にて同時に確認できる。すなわち、目視又は写真撮影によって、継手部材１６の連結位置が規定されていることを瞬時に確認することができる。   In addition, the situation in which the aiming portion 20 is aligned with the ends of the first reinforcing bar 12 and the second reinforcing bar 14 and the situation in which the portion of the first reinforcing bar 12 is marked with respect to the pipe member 18 are simultaneously visually observed. I can confirm. That is, it can be confirmed instantaneously that the connection position of the joint member 16 is defined by visual observation or photography.

また、図３（ａ）〜（ｃ）の断面図に示すように、装着する鉄筋用の管理治具であるかを鉄筋の径の大きさに基づいて識別することができる。図３（ａ）、（ｃ）は、装着する鉄筋４６、６０用の管理治具１０でない場合の例であり、図３（ｂ）は、装着する第１鉄筋１２用の管理治具１０である場合の例である。
Moreover, as shown to sectional drawing of Fig.3 (a)-(c), it can be discriminate | determined based on the magnitude | size of the diameter of a reinforcing bar whether it is the management jig | tool for the reinforcing bar to mount | wear. FIGS. 3A and 3C are examples in the case where the management jig 10 is not used for the reinforcing bars 46 and 60 to be mounted, and FIG. 3B is a management jig 10 for the first reinforcing bar 12 to be mounted. It is an example in some cases.

また、使用する鉄筋の最外径に合わせて管部材１８の内径等のサイズを設定すれば、検査時に鉄筋径の確認を行なうことができる。すなわち、管部材１８を鉄筋に装着した際に管部材１８と鉄筋との間の隙間が大きい場合、鉄筋径が小さいことがわかるので、誤った鉄筋が使用されるのを防ぐことができる。   Further, if the size such as the inner diameter of the pipe member 18 is set in accordance with the outermost diameter of the reinforcing bar to be used, the diameter of the reinforcing bar can be confirmed at the time of inspection. That is, when the pipe member 18 is attached to the reinforcing bar, if the gap between the pipe member 18 and the reinforcing bar is large, it can be seen that the diameter of the reinforcing bar is small, so that the wrong reinforcing bar can be prevented from being used.

以上、本発明の第１の実施形態について説明した。
なお、第１の実施形態では、第１鉄筋１２へ管部材１８を装着する例を示したが、第２鉄筋１４へ管部材１８を装着するようにしてもよい。 The first embodiment of the present invention has been described above.

However, the pipe member 18 may be formed of any material. For example, the pipe member 18 may be made of acrylic resin and wooden. Further, the pipe member may be attached by any method as long as the connection position of the joint member can be defined and the pipe member can be attached to the reinforcing bar to such an extent that photography can be performed. For example, the tube member may be an arc-shaped magnetic member in which the cylindrical member is vertically divided, or may be a dominant arc-shaped elastic member in which a slit is formed in the material axis direction of the cylindrical member.

また、第１の実施形態では、照準部２０をアクリルガラス等の透明な材料によって形成した例を示したが、第１鉄筋１２及び第２鉄筋１４の端部に合せられるものであればよく、例えば、照準部２０を半透明な材料によって形成してもよいし、覗き窓によって照準部を構成するようにしてもよい。   Moreover, in 1st Embodiment, although the example which formed the aiming part 20 with transparent materials, such as an acrylic glass, was shown, as long as it can match | combine with the edge part of the 1st rebar 12 and the 2nd rebar 14, For example, the aiming unit 20 may be formed of a translucent material, or the aiming unit may be configured by a viewing window.

Any member may be used. For example, a sponge or a rubber tube may be used.

また、第１の実施形態では、第１鉄筋１２へ装着した状態の管部材１８を方向Ｙへ移動させる例を示したが、第１鉄筋１２へ管部材１８を仮装着した状態（各ゴムシート２６を第１鉄筋１２へ軽く押し付けるようにして、外周部材２２Ａ、２２Ｂにより第１鉄筋１２を軽く挟み込んだ状態）で方向Ｙへ移動させ、その後、第１鉄筋１２へ管部材１８を完全に装着するようにしてもよい。   Moreover, although the example which moves the pipe member 18 in the state attached to the 1st reinforcing bar 12 to the direction Y was shown in 1st Embodiment, the state (temporarily attached to each rubber sheet) the pipe member 18 to the 1st reinforcing bar 12 26 is lightly pressed against the first rebar 12 and moved in the direction Y in a state where the first rebar 12 is lightly sandwiched by the outer peripheral members 22A and 22B), and then the pipe member 18 is completely attached to the first rebar 12 You may make it do.

In the description of the fourth embodiment, the same components as those in the first embodiment are denoted by the same reference numerals and are appropriately omitted.

図６（ａ）の側断面図に示すように、第４の実施形態の管理治具７０は、基準部材としてのゲージ棒７２、７４の一方端部に、位置合せ部としての目印領域７６、７８が設けられている。ゲージ棒７２、７４の他方端部は、接着剤等によって第１鉄筋１２、第２鉄筋１４の端部に固定された鋼製のキャップ部材８０、８２に着脱自在に装着されている。目印領域７６、７８は、継手部材１６が所定の連結位置に配置されたときに、継手部材１６の端部に位置するようにゲージ棒７２、７４に設けられている。   As shown in the side sectional view of FIG. 6 (a), the management jig 70 of the fourth embodiment has a mark region 76 as an alignment portion at one end of gauge bars 72 and 74 as reference members. 78 is provided. The other ends of the gauge bars 72 and 74 are detachably attached to steel cap members 80 and 82 fixed to the ends of the first rebar 12 and the second rebar 14 with an adhesive or the like. The mark regions 76 and 78 are provided on the gauge rods 72 and 74 so as to be positioned at the end portions of the joint member 16 when the joint member 16 is disposed at a predetermined connection position.

管理治具７０を用いた、継手部材内の鉄筋挿入長さ管理方法は、継手部材１６を移動させ、継手部材１６の端部が目印領域７６、７８に合ったところで継手部材１６の移動を止めて、キャップ部材８０、８２からゲージ棒７２、７４を外す。よって、継手部材１６の連結位置を規定することができ、これにより、継手部材１６への第１鉄筋１２と第２鉄筋１４との挿入長さを規定できる。   The reinforcing bar insertion length management method in the joint member using the management jig 70 moves the joint member 16 and stops the movement of the joint member 16 when the end of the joint member 16 matches the mark regions 76 and 78. Then, the gauge rods 72 and 74 are removed from the cap members 80 and 82. Therefore, the connection position of the joint member 16 can be defined, and thereby the insertion length of the first rebar 12 and the second rebar 14 into the joint member 16 can be defined.

図６（ｂ）、（ｃ）の側断面図には、管理治具７０の変形例が示されている。図６（ｂ）の管理治具８４では、第１鉄筋１２及び第２鉄筋１４の端面に、バネ８６によりキャップ部材８０、８２を押し付けることによって、キャップ部材８０、８２を第１鉄筋１２及び第２鉄筋１４に固定している。図６（ｃ）の管理部材８８では、キャップ部材８０にゲージ棒７４を着脱自在に装着し、キャップ部材８２にゲージ棒７２を着脱自在に装着している。   6 (b) and 6 (c) show modified examples of the management jig 70.

Moreover, you may form any one of the column member 34 and the beam member 36 by a cast-in-place concrete.

また、第１〜第４の実施形態では、継手部材１６を、第１鉄筋１２及び第２鉄筋１４を差し込むことにより挿入可能な差し込み式の機械式継手によって構成した例を示したが、第１及び第２の実施形態において、ねじ節鉄筋によって第１鉄筋１２及び第２鉄筋１４を構成し、継手部材１６を、第１鉄筋１２及び第２鉄筋１４を捩じ込むことにより挿入可能な捩じ込み式の機械式継手によって構成してもよい。   In the first to fourth embodiments, the example in which the joint member 16 is configured by a plug-in mechanical joint that can be inserted by inserting the first rebar 12 and the second rebar 14 has been described. And in 2nd Embodiment, the 1st rebar 12 and the 2nd rebar 14 are constituted by the screw rebar, and the joint member 16 can be inserted by screwing the first rebar 12 and the second rebar 14 into the screw. A built-in mechanical joint may be used.

また、第１〜第４の実施形態で示した、継手部材内の鉄筋挿入長さ管理方法は、継手部材１６により連結される全ての第１鉄筋１２及び第２鉄筋１４に対して行なってもよいが、梁部材３６の接合面４０から突出する全ての第１鉄筋１２の突出長さが略等しくなっており、柱部材３４の接合面３８から突出する全ての第２鉄筋１４の突出長さが略等しくなっている場合には、１つの第１鉄筋１２又は第２鉄筋１４に対して継手部材内の鉄筋挿入長さ管理方法により継手部材１６を配置し、この継手部材１６に合わせて残りの継手部材１６を配置してもよい。   Further, the reinforcing bar insertion length management method in the joint member shown in the first to fourth embodiments may be performed for all the first reinforcing bars 12 and the second reinforcing bars 14 connected by the joint member 16. Although the protruding lengths of all the first reinforcing bars 12 protruding from the joint surface 40 of the beam member 36 are substantially equal, the protruding lengths of all the second reinforcing bars 14 protruding from the connecting surface 38 of the column member 34 are good. Are substantially equal to each other, the joint member 16 is arranged with respect to one first rebar 12 or the second rebar 14 by the reinforcing bar insertion length management method in the joint member, and the rest is matched to the joint member 16. The joint member 16 may be arranged.

また、第１及び第２の実施形態では、第１鉄筋１２のマーク４２を基準にして継手部材１６を移動させる例を示したが、第１鉄筋１２にマークを付けずに、１つの第１鉄筋１２又は第２鉄筋１４に管理治具１０を取り付けて、残りの第１鉄筋１２又は第２鉄筋１４に設けられている継手部材１６をこの管理治具１０を基準にして移動させてもよい。   Moreover, although the example which moves the joint member 16 on the basis of the mark 42 of the 1st reinforcing bar 12 was shown in 1st and 2nd embodiment, without attaching a mark to the 1st reinforcing bar 12, one 1st 1st reinforcement The management jig 10 may be attached to the reinforcing bar 12 or the second reinforcing bar 14, and the joint member 16 provided on the remaining first reinforcing bar 12 or the second reinforcing bar 14 may be moved with reference to the management jig 10. .

また、第１〜第４の実施形態で示した、梁部材３６の接合面４０から突出する第１鉄筋１２、及び柱部材３４の接合面３８から突出する第２鉄筋１４の突出長さを、図７（ａ）〜（ｄ）の側断面図に示す方法により検査治具９０を用いて確認してもよい。   Moreover, the protrusion length of the 1st reinforcement 12 which protrudes from the joining surface 40 of the beam member 36 shown in the 1st-4th embodiment, and the 2nd reinforcement 14 which protrudes from the joining surface 38 of the column member 34, You may confirm using the inspection jig 90 by the method shown to the side sectional drawing of Fig.7 (a)-(d).

検査治具９０は、円筒状の部材であり、内部に突出部材９２が収容されている。また、突出部材９２には、第１表示部９４が設けられている。検査治具９０の各寸法は、図７（ｄ）に示すように、長さｄを鉄筋の許容最大突出長さとし、長さｅを鉄筋の許容最小突出長さよりも少し長くする。また、突出部材９２の長さｆを、検査治具９０の全長から長さｅを引いた長さにする。   The inspection jig 90 is a cylindrical member, and a protruding member 92 is accommodated therein. The protruding member 92 is provided with a first display portion 94. As shown in FIG. 7D, the dimensions of the inspection jig 90 are such that the length d is the maximum allowable protrusion length of the reinforcing bar and the length e is slightly longer than the minimum allowable protrusion length of the reinforcing bar. Further, the length f of the protruding member 92 is set to a length obtained by subtracting the length e from the entire length of the inspection jig 90.

第２鉄筋１４の突出長さが所定の長さであることを確認する場合には、図７（ａ）に示すように、確認対象となる第２鉄筋１４が検査治具９０の中空部９６に挿入されるようにして、検査治具９０を第２鉄筋１４にセットする。そして、検査治具９０の末端面９８を柱部材３４の接合面３８に当てた状態で、第１表示部９４が検査治具９４の先端面１００から突出するか否かによって、第２鉄筋１４の突出長さが所定の長さであるかどうかを判断する。   When it is confirmed that the protruding length of the second rebar 14 is a predetermined length, the second rebar 14 to be confirmed is a hollow portion 96 of the inspection jig 90 as shown in FIG. The inspection jig 90 is set on the second rebar 14 so as to be inserted into the second rebar 14. Then, depending on whether or not the first display portion 94 protrudes from the distal end surface 100 of the inspection jig 94 with the end surface 98 of the inspection jig 90 in contact with the joint surface 38 of the column member 34, the second rebar 14. It is determined whether or not the protruding length of is a predetermined length.

第２鉄筋１４の突出長さが所定の長さの許容範囲内にある場合には、図７（ｂ）に示すように、検査治具９０の先端面１００から第１表示部９４が突出する。また、第２鉄筋１４の突出長さが所定の長さの許容範囲よりも小さい場合には、図７（ｃ）に示すように、検査治具９０の先端面１００から第１表示部９４が突出しない。また、第２鉄筋１４の突出長さが所定の長さの許容範囲よりも大きい場合には、図７（ｄ）に示すように、検査治具９０の末端面９８を柱部材３４の接合面３８に当てることができない。   When the protruding length of the second reinforcing bar 14 is within the allowable range of the predetermined length, as shown in FIG. 7B, the first display portion 94 protrudes from the tip surface 100 of the inspection jig 90. . Further, when the protruding length of the second reinforcing bar 14 is smaller than the allowable range of the predetermined length, as shown in FIG. Does not protrude.
