The two legs 13 and 14 of the first frame are arranged on the same axis, and the first frame-side separate leg 14 and the second frame-side leg 16 are arranged to face each other in a parallel state. In addition, the first frame body-side separate leg portion 14 extends from the end of the continuous portion 19 on the first frame body 12A side toward the inner side in the width direction.

上記連結部17は、上記一対の枠体12A,12Bの一方から他方に連続して両者を連結固定している。言換えると、連結部17は、枠体12から鉄筋4,6の軸方向の延びる延設部であるとともに、一対の枠体12A,12Bの一方から他方に連続する連続部でもある。   The connecting portion 17 is connected and fixed continuously from one of the pair of frame bodies 12A and 12B to the other. In other words, the connecting portion 17 is an extending portion extending in the axial direction of the reinforcing bars 4 and 6 from the frame body 12 and is also a continuous portion continuing from one to the other of the pair of frame bodies 12A and 12B.

この連結部17は、上下一対で設けられている。上側の連結部17である上側連結部17Aは、一対の枠体12,12における本体部18,18の上端部同士を連結し、下側の連結部17である下側連結部17Bは、第1枠体側一体脚部13と、第2枠体側脚部16の幅方向内側端部とを連結しており、この一対の連結部17A,17Bは、平面視で、鉄筋4,6位置に配置形成されている。   This connection part 17 is provided in a pair of upper and lower sides. The upper connecting portion 17A that is the upper connecting portion 17 connects the upper end portions of the main body portions 18 and 18 in the pair of frame bodies 12 and 12, and the lower connecting portion 17B that is the lower connecting portion 17 is the first connecting portion 17A. The one frame body side integrated leg portion 13 and the inner end portion in the width direction of the second frame body side leg portion 16 are connected, and the pair of connecting portions 17A and 17B are arranged at positions of the reinforcing bars 4 and 6 in plan view. Is formed.

すなわち、第2枠体側脚部16→下側連結部17B→第1枠体側一体脚部13→第1枠体12Aの本体部18→上側連結部17A→第2枠体12Bの本体部18→連続部19→第1枠体側別体脚部14の順番及びこの逆の順番で各部が連続し、このため、単一の棒状部材bを曲げ加工することにより、各部がまとめて形成可能となる。   That is, the second frame body side leg portion 16 → the lower connection portion 17B → the first frame body side integrated leg portion 13 → the main body portion 18 of the first frame body 12A → the upper connection portion 17A → the main body portion 18 of the second frame body 12B → Each part is continuous in the order of the continuous part 19 → the first frame side separate leg part 14 and the reverse order thereof. Therefore, by bending the single rod-shaped member b, the parts can be formed together. .

各連結部17には、鉄筋4,6の軸方向視で、U字状又はV字状(図示する例では、U字状)をなす溝部21が設けられている。この溝部21の底側には、鉄筋4,6の軸方向視で、該鉄筋4,6の外周面の半円を越える範囲(図示する例では、3分の2周以上の範囲)に沿う円弧状をなす係合部21aが形成されている。言換えると、係合部21aは、半円を越える円弧状に形成されている。   Each connecting portion 17 is provided with a groove portion 21 that is U-shaped or V-shaped (in the illustrated example, U-shaped) when the reinforcing bars 4 and 6 are viewed in the axial direction. On the bottom side of the groove portion 21, along the axial direction of the reinforcing bars 4, 6, a range exceeding the semicircle of the outer peripheral surface of the reinforcing bars 4, 6 (in the illustrated example, a range of two thirds or more) An engaging portion 21a having an arc shape is formed. In other words, the engaging portion 21a is formed in an arc shape exceeding a semicircle.

溝部21の係合部21a以外の部分は、開放端から溝部側への方向(深さ方向)に向かって、幅が次第に縮小し、溝部21の円弧状の係合部21a側で再び幅が拡大される。このため、係合部21aに鉄筋4,6の周面を嵌合して係脱自在に係合させる際には、棒状部材bの材質等によって、溝部21を、弾力的に幅方向に拡大・縮小変更可能な構造とし、これによって、鉄筋4,6を、周面側から、溝部21に嵌合挿入して、該周面を弾力的に係止させることが可能になる。   The portion of the groove portion 21 other than the engagement portion 21a gradually decreases in width in the direction from the open end to the groove portion side (depth direction), and the width is increased again on the arcuate engagement portion 21a side of the groove portion 21. Enlarged. Therefore, when the peripheral surfaces of the reinforcing bars 4 and 6 are fitted to the engaging portion 21a so as to be freely disengaged, the groove portion 21 is elastically expanded in the width direction depending on the material of the rod-like member b. A structure that can be reduced and changed, whereby the reinforcing bars 4 and 6 can be fitted and inserted into the groove portion 21 from the peripheral surface side to elastically lock the peripheral surface.

ところで、連結部17は、溝部21の幅方向の一方側半部(溝半部)22が一の枠体12A側に形成されるとともに、溝部21の幅方向他方側半部(溝半部)23が、もう片方の枠体12B側に形成されている。この一対の溝半部22,23の底側端部同士が、鉄筋4,6の軸方向に沿う(図示する例では平行な)サポート部24によって、連結されている。   By the way, as for the connection part 17, while the one side half part (groove half part) 22 of the width direction of the groove part 21 is formed in the one frame 12A side, the width direction other side half part (groove half part) of the groove part 21 is formed. 23 is formed on the other frame 12B side. The bottom end portions of the pair of groove halves 22 and 23 are connected to each other by a support portion 24 (parallel in the illustrated example) along the axial direction of the reinforcing bars 4 and 6.

また、該一対の各溝半部22,23は、枠体12A,12Bから溝部21の深さ方向に突出し、この溝半部22,23の突出端部(先端部)は、幅方向内側に曲げ形成されている。このため、各溝半部22,23は、鉄筋4,6の軸方向視で、フック状に形成されている。さらに、一対の溝半部22,23は、鉄筋4,6の軸方向視で、該鉄筋4,6を境に対称形状をなし、その先端部同士の間に、鉄筋4,6の軸方向に延びる上述のサポート部24が架設され、両者は連続している。このため、サポート部24は、鉄筋4,6の係合時に、鉄筋4,6の周面に沿ってサポートする状態になる。   Further, the pair of groove halves 22 and 23 protrude from the frame bodies 12A and 12B in the depth direction of the groove 21, and the projecting ends (tips) of the groove halves 22 and 23 are inward in the width direction. It is bent. For this reason, each groove | channel half part 22 and 23 is formed in the hook shape by the axial view of the reinforcing bars 4 and 6. FIG. Further, the pair of groove halves 22 and 23 are symmetrical with respect to the reinforcing bars 4 and 6 as viewed in the axial direction of the reinforcing bars 4 and 6, and the axial direction of the reinforcing bars 4 and 6 is between the tips. The above-described support portion 24 extending to the center is erected, and both are continuous. For this reason, the support part 24 will be in the state supported along the surrounding surface of the reinforcing bars 4 and 6 at the time of engagement of the reinforcing bars 4 and 6.

ちなみに、上側連結部17Aの溝部21は上方が開放され、下側連結部17Bは下方が開放されており、各連結部17は、一方の溝半部22と、サポート部24と、他方の溝半部23とがこの順序及びこの順序と逆の順序で連続形成されて構成されている。   Incidentally, the upper portion of the groove portion 21 of the upper connecting portion 17A is open, the lower portion of the lower connecting portion 17B is open, and each connecting portion 17 includes one groove half portion 22, a support portion 24, and the other groove. The half part 23 is continuously formed in this order and in the reverse order.

該構成の検測枠8では、格子状に配置された下側鉄筋6に対して、鉄筋6方向に複数の検測枠8を並べて配置する際に、各検測枠8の下側連結部17Bの係合部21aに該鉄筋6が周面側から係合されて嵌合係止されるようにして、下側鉄筋側6に検測枠8を位置決め係止させる。   In the measurement frame 8 having such a configuration, when the plurality of measurement frames 8 are arranged side by side in the rebar 6 direction with respect to the lower rebar 6 arranged in a lattice shape, the lower connection portion of each measurement frame 8 The measuring frame 8 is positioned and locked to the lower reinforcing bar side 6 so that the reinforcing bar 6 is engaged and locked to the engaging portion 21a of 17B from the peripheral surface side.

続いて、上側鉄筋4を、上記検測枠8の上側連結部17Aの係合部21aに、周面側から係合させることにより、上側鉄筋4を設置する。   Subsequently, the upper rebar 4 is installed by engaging the upper rebar 4 with the engaging portion 21a of the upper connecting portion 17A of the measurement frame 8 from the peripheral surface side.

対応する係合部21aに弾力的に係止された各鉄筋4,6は、別途固定具を用いて、検測枠に固定させる必要がなく、作業工程が省略化される。   The reinforcing bars 4 and 6 elastically locked to the corresponding engaging portions 21a do not need to be separately fixed to the measurement frame by using a fixing tool, and the work process is omitted.

また、鉄筋4,6を係止させる溝部21を構成する一対の溝半部22,23は、互いに鉄筋4,6方向にずらされているため、鉄筋4,6の溝部21内への係止を簡単に行うことが可能になる他、鉄筋4,6の軸方向にずらして配置された一対のフック状の溝半部22,23は、サポート部24と共に、安定的に鉄筋4,6を保持することが可能になるため、鉄筋4,6の支持安定性も向上する。   Further, since the pair of groove halves 22 and 23 constituting the groove portion 21 for engaging the reinforcing bars 4 and 6 are shifted from each other in the direction of the reinforcing bars 4 and 6, the reinforcing bars 4 and 6 are locked in the groove portion 21. The pair of hook-shaped groove halves 22 and 23 arranged so as to be shifted in the axial direction of the reinforcing bars 4 and 6 together with the support part 24 can stably connect the reinforcing bars 4 and 6. Since it becomes possible to hold | maintain, the support stability of the reinforcing bars 4 and 6 is also improved.

また、複数の脚部13,14,16によって、検測枠8は、安定して自立するため、利便性が高く、さらに間隔Lを十分に確保することによって、自立時の安定性がより向上する。また、この間隔Lは、鉄筋4,6を安定的に支持するとうい観点からも、長さの設定がなされている。   In addition, the measurement frame 8 is stable and independent due to the plurality of legs 13, 14, and 16, and thus is highly convenient. Further, by securing a sufficient interval L, the stability during independence is further improved. To do. The distance L is also set from the viewpoint of stably supporting the reinforcing bars 4 and 6.

次に、図5乃至図6に基づき、検測枠8の別実施形態について上述した形態と異なる点を説明する。   Next, based on FIG. 5 thru | or FIG. 6, a different point from the form mentioned above about another embodiment of the measurement frame 8 is demonstrated.

図5,図6は、別実施形態に係る検測枠の構成を示す斜視図及び正面図である。図示する検測枠は、単一の枠体12のみからなる。枠体12の本体部18は、鉄筋4,6の軸方視で、法枠1における半円山形状の断面形状の全体に沿う半円の円弧状に成形されている。   5 and 6 are a perspective view and a front view showing a configuration of a measurement frame according to another embodiment. The inspection frame shown is composed of only a single frame 12. The main body 18 of the frame 12 is formed in a semicircular arc shape along the entire semicircular cross-sectional shape of the normal frame 1 in the axial view of the reinforcing bars 4 and 6.

この本体部18の両端部からは、法枠1の幅方向内側に向かって、それぞれ脚部26,27が延出される。言換えると、枠体12は、1つの本体部18と、一対の脚部26,27によって、構成されている。また、本体部18の法枠1の幅方向中央部には、鉄筋4,6の軸方向視で、U字状又はV字状(図示する例ではU字状)をなす溝部21が形成されている   Legs 26 and 27 extend from both ends of the main body 18 toward the inner side in the width direction of the frame 1. In other words, the frame body 12 is constituted by one main body portion 18 and a pair of leg portions 26 and 27. Further, a groove portion 21 having a U shape or a V shape (U shape in the illustrated example) is formed in the central portion in the width direction of the normal frame 1 of the main body portion 18 when the reinforcing bars 4 and 6 are viewed in the axial direction. ing

溝部21内には、上側鉄筋4,6を、周面から側から挿入して嵌合係止させるため、この溝部21の底側が鉄筋4,6を係合させる係合部21aになる。この溝部21は、上述の形態ではサポート部24を介して、2つの枠体12,12に跨るように形成されていたが、本形態では、1つの枠体12に連続形成されている。   In the groove portion 21, the upper rebars 4, 6 are inserted from the peripheral surface and fitted and locked, so that the bottom side of the groove portion 21 becomes an engaging portion 21 a for engaging the rebars 4, 6. The groove portion 21 is formed so as to straddle the two frame bodies 12 and 12 via the support portion 24 in the above-described form, but is continuously formed on the single frame body 12 in the present embodiment.

脚部26,27は、互いに平行な状態で、一部が正面視で、重複するようにして、鉄筋4,6の軸方向にずらして配置されている。このため、本体部18は、平面視で、法枠1の幅方向に対して若干傾斜した状態となる。   The leg portions 26 and 27 are arranged in parallel with each other and are shifted in the axial direction of the reinforcing bars 4 and 6 so as to partially overlap in front view. For this reason, the main body 18 is slightly inclined with respect to the width direction of the method frame 1 in plan view.

ちなみに、この一対の脚部26,27の間には、枠体12の外側から内側、或いは内側から外側への鉄筋6の周面側からの通過を許容する許容スペース(第1許容スペース)S1が形成されている。この他、鉄筋6の軸方向で、本体部18及び一対の脚部26,27に囲繞された空間も、鉄筋6の枠体18内での移動を許容する許容スペース(第2許容スペース)S2となる。   Incidentally, between the pair of leg portions 26 and 27, an allowable space (first allowable space) S1 that allows passage of the reinforcing bar 6 from the outer side to the inner side or from the inner side to the outer side from the peripheral surface side. Is formed. In addition, the space surrounded by the main body 18 and the pair of legs 26 and 27 in the axial direction of the reinforcing bar 6 is also an allowable space (second allowable space) S2 that allows the reinforcing bar 6 to move within the frame 18. It becomes.

一方の脚部26の延出側端部は平面視で鉄筋6位置とラップしており、この延出側端部からは鉄筋6の軸方向に向かって延設部17が延出されている。具体的には、該延設部17は、上記一方の脚部26の延出側端部から垂直に立上る起立部28と、該起立部28の上端部からは、他方の脚部27側に向かって螺旋状に延びる係合部29とから構成されている。   The extension side end portion of one leg portion 26 is overlapped with the position of the reinforcing bar 6 in a plan view, and the extension portion 17 extends from the extension side end portion in the axial direction of the reinforcing bar 6. . Specifically, the extended portion 17 includes an upright portion 28 that rises perpendicularly from the extending side end portion of the one leg portion 26, and the other leg portion 27 side from the upper end portion of the upright portion 28. And an engaging portion 29 extending in a spiral shape.

この螺旋状に形成された係合部29内に鉄筋6を挿通させ、その周面を係合して係止させる。これに加えて、この螺旋状の係合部29を構成し且つ該延出させた方向で隣接する環状部分同士の間には、鉄筋6の周面側からの通過を許容する許容スペース(第3許容スペース)S3が形成されている。   The rebar 6 is inserted into the engagement portion 29 formed in a spiral shape, and its peripheral surface is engaged and locked. In addition to this, between the annular portions that constitute the helical engagement portion 29 and that are adjacent in the extending direction, an allowable space (first step) that allows passage of the reinforcing bar 6 from the circumferential surface side is allowed. 3 allowable space) S3 is formed.

この検測枠8の設置手段について説明すると、最初に、複数の上側鉄筋4及び下側鉄筋6を、法面2上に格子状に配筋し、この状態で、上側鉄筋4の溝部21内への係合作業や、下側鉄筋6の螺旋状の係合部29へ係合作業を行うが、この際、鉄筋4,6の端部側からの溝部21内への挿入や、螺旋状の係合部29内への挿入を行うことができない。   The means for installing the inspection frame 8 will be described. First, a plurality of upper rebars 4 and lower rebars 6 are arranged in a lattice pattern on the slope 2, and in this state, in the groove portion 21 of the upper rebar 4. The engaging operation is performed on the spiral engaging portion 29 of the lower rebar 6. At this time, insertion into the groove portion 21 from the end side of the reinforcing bars 4 and 6, Cannot be inserted into the engaging portion 29.

このため、まず、この下側鉄筋6の周面を、螺旋状の係合部29に挿通して係止させ、その後、上側鉄筋4の周面を、溝部21内に嵌合挿入させて係止させる。この際における下側鉄筋6の螺旋状の係合部29への係合作業について以下に詳述する。   For this reason, first, the peripheral surface of the lower rebar 6 is inserted and locked into the spiral engaging portion 29, and then the peripheral surface of the upper rebar 4 is fitted and inserted into the groove portion 21. Stop. The engagement operation of the lower rebar 6 with the helical engagement portion 29 at this time will be described in detail below.

図7(A)乃至(D)は、下側鉄筋を係合部に係合させる工程を順次示す斜視図である。ちなみに、実際は、下側鉄筋6に対して、検測枠8の姿勢変更や、移動等を行うが、この際、検測枠8に対して下側鉄筋6は、相対的に姿勢変更及び移動されることになり、同図には、この状態が示されている。   FIGS. 7A to 7D are perspective views sequentially showing steps of engaging the lower reinforcing bar with the engaging portion. By the way, in practice, the posture of the inspection frame 8 is changed or moved with respect to the lower rebar 6. At this time, the lower rebar 6 is relatively changed in posture and moved with respect to the inspection frame 8. This state is shown in FIG.

最初に、第1許容スペースS1を介して、下側鉄筋6の周面を、枠体12内に挿通させる(同図(A)参照)。続いて、枠体12内において、第2許容スペースS2を介して、螺旋状の係合部29側に下側鉄筋6を変位させ、さらに詳しくは、螺旋状の係合部29における最初の環状部分に下側鉄筋6の周面を変位させる(同図(B)参照)。   First, the peripheral surface of the lower reinforcing bar 6 is inserted into the frame body 12 through the first allowable space S1 (see FIG. 5A). Subsequently, in the frame body 12, the lower reinforcing bar 6 is displaced toward the spiral engaging portion 29 via the second allowable space S <b> 2, and more specifically, the first annular shape in the spiral engaging portion 29 is arranged. The peripheral surface of the lower rebar 6 is displaced to a portion (see FIG. 5B).

続いて、下側鉄筋6の周面を、第3許容スペースS3内に変位させ(同図(C)参照)、螺旋状の係合部29における次の環状部分に下側鉄筋6の周面を位置させ(同図(D)参照)、この作業を螺旋状の係合部29における最後の環状部分に下側鉄筋6の周面が変位するまで繰返し、これよって、下側鉄筋6を螺旋状の係合部29に挿通させる。ちなみに、上記3つの許容スペースS1,S2,S3の弾力的な拡大・縮小が可能なように、棒状部材は、弾性変形可能な部材で構成される。   Subsequently, the peripheral surface of the lower reinforcing bar 6 is displaced into the third allowable space S3 (see FIG. 3C), and the peripheral surface of the lower reinforcing bar 6 is placed on the next annular portion in the spiral engaging portion 29. (See FIG. 4D), this operation is repeated until the peripheral surface of the lower rebar 6 is displaced to the final annular portion of the helical engagement portion 29, whereby the lower rebar 6 is spirally moved. Is inserted into the engagement portion 29. Incidentally, the rod-like member is formed of a member that can be elastically deformed so that the three allowable spaces S1, S2, and S3 can be elastically expanded and reduced.

以上のように構成される検測枠8によれば、第1許容スペースS1を空けて配置された一対の脚部26,27によって、枠体12が自立可能になる。   According to the inspection frame 8 configured as described above, the frame body 12 can stand on its own by the pair of leg portions 26 and 27 arranged with the first allowable space S1 therebetween.

また、延設部17→一方の脚部26→本体部18→他方の脚部27の順及びこの逆の順で各部が連続形成されるため、単一の上記棒状部材bを曲げ加工することによって、各部を形成できる。   Further, since each part is continuously formed in the order of the extension part 17 → one leg part 26 → the main body part 18 → the other leg part 27 and vice versa, the single rod-like member b is bent. Thus, each part can be formed.

また、鉄筋6の軸方向に沿って延びる螺旋状の係合部29への該鉄筋6の挿通によって、該鉄筋6を支持して保持するため、鉄筋6をより安定的に保持させることが可能になる。   Further, since the reinforcing bar 6 is supported and held by inserting the reinforcing bar 6 into the spiral engaging portion 29 extending along the axial direction of the reinforcing bar 6, the reinforcing bar 6 can be held more stably. become.

さらに、鉄筋4,6を配筋した後に、検測枠8を設置できるため、利便性が高い。   Furthermore, since the inspection frame 8 can be installed after the reinforcing bars 4 and 6 are arranged, the convenience is high.

なお、上側鉄筋4は、省略も可能であり、この場合には、本体部18に形成された溝部21も省略させる。   Note that the upper reinforcing bar 4 can be omitted, and in this case, the groove portion 21 formed in the main body portion 18 is also omitted.
