従来、コンクリート基礎の現場打ち工法においては、まず、型枠内に異形棒鋼を用いて配筋し、コンクリートを打設した後、さらにその天端面にレベラーを流し込んで、基礎コンクリート全体の天端を均一な面にすることが行われている。このレベラーを流し込むときの上面の目印として、天端レベル管理具が用いられる。 Conventionally, in the concrete foundation on-site method, first of all, after placing bar using deformed steel bar in the formwork, placing concrete, leveler is poured into the top end surface, and the top end of the entire foundation concrete is A uniform surface is used. A top level control tool is used as a mark on the upper surface when the leveler is poured.
例えば、特許文献１には、調整軸部材の下端側外壁に固定されて鉄筋に着脱自在に取り付けられる鉄筋取付部材を備えた天端出し治具が記載されている。図１６は特許文献１に記載の天端出し治具を示す正面図、図１７は図１６の天端出し治具の鉄筋取付部材を示す一部破断正面図、図１８は同鉄筋取付部材を示す平面図である。 For example, Patent Document 1 describes a top end jig including a reinforcing bar attachment member that is fixed to a lower end side outer wall of an adjustment shaft member and is detachably attached to the reinforcing bar. 16 is a front view showing the top end fitting jig described in Patent Document 1, FIG. 17 is a partially broken front view showing the reinforcing bar attaching member of the top end fitting jig of FIG. 16, and FIG. FIG.
図１６〜図１８に示すように、この天端出し治具１１０の鉄筋取付部材１１８は、調整軸部材１１１に着脱可能に取り付けられる円筒状の第１取付部１１９と、鉄筋に着脱可能に取り付けられる略円筒状の第２取付部１２３とが軸方向を揃えてかつ隣接して一体で形成されている。また、第２取付部１２３は、軸方向下端近傍位置にて、内周面からわずかに突出したリング状の係止部１２６を設けており、鉄筋に装着されたときに鉄筋の突起に係止されて、軸方向に移動しないように確実に鉄筋に固定されるようになっている。 As shown in FIGS. 16 to 18, the reinforcing bar attaching member 118 of the top end jig 110 is attached to the adjusting shaft member 111 so as to be detachable, and is attached to the reinforcing bar so as to be detachable. The substantially cylindrical second mounting portion 123 is integrally formed with the axial direction aligned and adjacent. The second mounting portion 123 is provided with a ring-shaped locking portion 126 slightly protruding from the inner peripheral surface at a position near the lower end in the axial direction, and is locked to the protrusion of the reinforcing bar when attached to the reinforcing bar. Thus, it is securely fixed to the reinforcing bar so as not to move in the axial direction.
ところで、コンクリート基礎の配筋に用いられる鉄筋は、軸線方向に所定のピッチで複数の凸状の節が形成された異形棒鋼である。上記従来の天端出し治具１１０の鉄筋取付部材１１８は、第２取付部１２３の軸方向下端近傍位置にて内周面からわずかに突出したリング状の係止部１２６が、この異形棒鋼の凸状の節（突部）に係止されることにより、軸方向に移動しないように固定されるというものであるが、このリング状の係止部１２６は節と節との間で上下に移動してしまう可能性がある。 By the way, the reinforcing bar used for the reinforcement of the concrete foundation is a deformed steel bar in which a plurality of convex nodes are formed at a predetermined pitch in the axial direction. The reinforcing bar mounting member 118 of the conventional top end protruding jig 110 has a ring-shaped locking portion 126 slightly protruding from the inner peripheral surface at a position near the lower end in the axial direction of the second mounting portion 123. It is fixed so that it does not move in the axial direction by being locked to a convex node (protrusion), but this ring-shaped locking portion 126 is vertically moved between the nodes. There is a possibility of moving.

図１および図２に示すように、本発明の実施の形態における天端レベル管理具１は、表面に凹凸の突起を有する異形棒鋼を用いて型枠内に配筋し、コンクリートを打設した後、さらにその天端面にレベラーを流し込んで基礎天端を形成するときの天端レベルを設定する治工具である。天端レベル管理具１は、延在方向（軸線方向）Ｘ１を垂直方向とする縦筋Ｒ１および延在方向（軸線方向）Ｘ２を水平方向とする横筋Ｒ２からなる配筋のうち、縦筋Ｒ１に取り付けられる天端レベル管理具本体２と、天端レベル管理具本体２に保持されて天端レベルの目印とするレベル設定用棒材３とからなる。縦筋Ｒ１および横筋Ｒ２は、軸線方向に所定のピッチで複数の凸状の節Ｇ１が形成された異形棒鋼である。 As shown in FIG. 1 and FIG. 2, the top level control tool 1 according to the embodiment of the present invention uses a deformed steel bar having uneven projections on the surface thereof to place a bar in a formwork and cast concrete. Later, it is a jig that sets the top end level when a leveler is poured into the top end face to form the base top end. The top level management tool 1 includes the vertical streak R1 among the reinforcing bars composed of the vertical streak R1 having the extending direction (axial direction) X1 as the vertical direction and the horizontal streak R2 having the extending direction (axial direction) X2 as the horizontal direction. The top end level management tool main body 2 attached to the top end and the level setting bar 3 which is held by the top end level management tool main body 2 and serves as a mark of the top end level. The vertical bars R1 and the horizontal bars R2 are deformed steel bars in which a plurality of convex nodes G1 are formed at a predetermined pitch in the axial direction.
天端レベル管理具本体２およびレベル設定用棒材３は、硬質樹脂で形成されている。硬質樹脂としては、例えばＰＰ（ポリプロピレン）、ＰＯＭ（ポリアセタール）、ＡＢＳ樹脂、ＰＣ（ポリカーボネート）やＰＡ６（ポリアミド）等の工業用プラスチック樹脂を用いることができる。また、摺動性が良い複数種類の硬質樹脂を組み合わせて使用することも可能である。 The top end level management tool body 2 and the level setting bar 3 are made of hard resin. As the hard resin, for example, an industrial plastic resin such as PP (polypropylene), POM (polyacetal), ABS resin, PC (polycarbonate) or PA6 (polyamide) can be used. It is also possible to use a combination of a plurality of hard resins having good slidability.
レベル設定用棒材３は、丸棒状に形成され、上端３０を、レベラーを流し込んで基礎天端を形成するときの天端レベルの目印としている。また、レベル設定用棒材３の上端から予定距離、例えば１０ｍｍだけ下がった位置には、レベル設定用棒材３から両側に拡がる鱗状の拡径部３１が設けられている。拡径部３１の上面は、レベラーを流す前に打設するコンクリートの上端レベルの目印となっている。 The level setting bar 3 is formed in a round bar shape, and the upper end 30 is used as a mark of the top end level when the leveler is poured into the base top end. Further, a scale-like diameter-expanding portion 31 that extends from the level setting bar 3 to both sides is provided at a position that is lower than the upper end of the level setting bar 3 by a predetermined distance, for example, 10 mm. The upper surface of the enlarged diameter portion 31 serves as a mark for the upper end level of the concrete to be placed before flowing the leveler.
レベル設定用棒材３の下部には、螺旋状の溝部３２が形成されている。溝部３２の内径は、レベル設定用棒材３の上部の外径と同じに形成され、強度の低下が防止されている。また、溝部３２の断面形状は、矩形波状に形成され、衝撃が加わったときや、摺動による破損を防止している。溝部３２の溝は１条で、ピッチは例えば３．０〜３．５ｍｍに形成されている。 A spiral groove 32 is formed below the level setting bar 3. The inner diameter of the groove portion 32 is formed to be the same as the outer diameter of the upper portion of the level setting bar 3, and the strength is prevented from decreasing. Moreover, the cross-sectional shape of the groove part 32 is formed in a rectangular wave shape, and prevents damage caused by an impact or sliding. The groove 32 has a single groove and a pitch of, for example, 3.0 to 3.5 mm.
図４〜図１１に示すように、天端レベル管理具本体２は、レベル設定用棒材３の上下位置を調整して保持可能な保持部１０と、縦筋Ｒ１に取り付けられる縦筋取付部１１と、縦筋取付部１１から縦筋Ｒ１が脱落するのを防止する脱落防止部１２とを備える。 As shown in FIGS. 4 to 11, the top level management tool main body 2 includes a holding portion 10 that can be held by adjusting the vertical position of the level setting bar 3, and a vertical bar attachment portion that is attached to the vertical bar R <b> 1. 11 and a dropout prevention portion 12 that prevents the vertical stripe R1 from dropping off from the vertical stripe attachment portion 11.
保持部１０は、上下方向に延びる略円筒状であって上下方向のスリット１０ａを有し、上下方向からみて略Ｃ字状に形成されたものである。保持部１０の内径は、レベル設定用棒材３の溝部３２が形成された下部外周に当接して保持可能な程度の大きさに設定されている。また、保持部１０の内側の上端部には、レベル設定用棒材３の溝部３２に嵌入する突起部１０ｂを有する。レベル設定用棒材３は、この突起部１０ｂが溝部３２に嵌入することによって、ねじのように回転させることができ、１回転につき上下に３．０〜３．５ｍｍ移動する。 The holding part 10 has a substantially cylindrical shape extending in the vertical direction, has a slit 10a in the vertical direction, and is formed in a substantially C shape when viewed from the vertical direction. The inner diameter of the holding part 10 is set to such a size that it can be held in contact with the outer periphery of the lower part where the groove part 32 of the level setting bar 3 is formed. In addition, the upper end portion on the inner side of the holding portion 10 has a protruding portion 10 b that fits into the groove portion 32 of the level setting bar 3. The level setting bar 3 can be rotated like a screw by inserting the protrusion 10b into the groove 32, and moves up and down 3.0 to 3.5 mm per rotation.
縦筋取付部１１は、上下方向に延びる略円筒状であって上下方向の開口１１ａを有し、上下方向からみて略Ｃ字状に形成されたものである。縦筋取付部１１の内径は、縦筋Ｒ１の外径に対応する大きさであり、縦筋Ｒ１の凸状の節Ｇ１まで含めた外径よりも若干小さく、形成されている。また、縦筋取付部１１には、縦筋Ｒ１の複数の凸状の節Ｇ１がそれぞれ嵌入する複数の間隙からなる節嵌入部２０が節Ｇ１のピッチに応じたピッチで形成されている。 The vertical streak attachment portion 11 has a substantially cylindrical shape extending in the vertical direction, has an opening 11a in the vertical direction, and is formed in a substantially C shape when viewed from the vertical direction. The inner diameter of the vertical bar attachment portion 11 is a size corresponding to the outer diameter of the vertical bar R1, and is formed slightly smaller than the outer diameter including the convex node G1 of the vertical bar R1. In addition, in the vertical stripe attaching portion 11, node insertion portions 20 each having a plurality of gaps into which the plurality of convex nodes G1 of the vertical stripe R1 are respectively inserted are formed at a pitch corresponding to the pitch of the node G1.
縦筋取付部１１の開口１１ａが縦筋Ｒ１に横方向から押し当てられると、縦筋取付部１１が弾性変形して開口１１ａが拡がり、縦筋Ｒ１が開口１１ａを通過する。その後、縦筋取付部１１が弾性復元することにより、縦筋Ｒ１が縦筋取付部１１に嵌合する。このとき、縦筋Ｒ１の複数の凸状の節Ｇ１は、節嵌入部２０にそれぞれ嵌入して位置決めされ、縦筋取付部１１はその位置に縦筋Ｒ１に固定される。 When the opening 11a of the vertical stripe attachment portion 11 is pressed against the vertical stripe R1 from the lateral direction, the vertical stripe attachment portion 11 is elastically deformed to expand the opening 11a, and the vertical stripe R1 passes through the opening 11a. Thereafter, the vertical bar attachment portion 11 is elastically restored, so that the vertical bar R1 is fitted to the vertical bar attachment portion 11. At this time, the plurality of convex nodes G1 of the vertical bars R1 are respectively inserted and positioned in the node insertion portions 20, and the vertical bar attachment portions 11 are fixed to the vertical bars R1 at the positions.
脱落防止部１２は、縦筋取付部１１の上側に設けられている。脱落防止部１２は、縦筋取付部１１の略Ｃ字状の開口１１ａを挟む左右両側からそれぞれ外側に延びる第１アーム２２と、第１アーム２２の先端部で折り返して縦筋取付部１１の略Ｃ字状の開口に向かって延びる第２アーム２３とからそれぞれ構成される左右一対のアーム２１からなる。アーム２１の先端、すなわち第２アーム２３の先端２４は、縦筋取付部１１に取り付けられた縦筋Ｒ１に対峙する位置に設けられている。 The drop-off prevention part 12 is provided on the upper side of the vertical bar attachment part 11. The drop-off prevention part 12 is folded back at the first arm 22 extending outward from the left and right sides sandwiching the substantially C-shaped opening 11a of the vertical bar attachment part 11 and the distal end of the first arm 22, and the vertical bar attachment part 11 It consists of a pair of left and right arms 21 each composed of a second arm 23 extending toward a substantially C-shaped opening. The distal end of the arm 21, that is, the distal end 24 of the second arm 23 is provided at a position facing the longitudinal stripe R 1 attached to the longitudinal stripe attachment portion 11.
この左右一対のアーム２１は、左右一対のアーム２１間に縦筋Ｒ１が外側から挿入される際には弾性変形、特に第２アーム２３の部分が弾性変形して左右一対のアーム２１の間隔が拡がり、左右一対のアーム２１間を縦筋Ｒ１が通過した際に、左右一対のアーム２１の先端２４が縦筋Ｒ１に対峙する位置に弾性復帰する。 The pair of left and right arms 21 are elastically deformed when the longitudinal muscle R1 is inserted between the pair of left and right arms 21 from the outside, and particularly, the portion of the second arm 23 is elastically deformed so that the distance between the pair of left and right arms 21 is increased. When the longitudinal muscle R1 passes between the pair of left and right arms 21, the distal ends 24 of the pair of left and right arms 21 elastically return to positions where they face the longitudinal muscle R1.
上記構成の天端レベル管理具１では、天端レベル管理具本体２を図３に示すように縦筋Ｒ１に装着すると、縦筋取付部１１に形成された節嵌入部２０に、異形棒鋼からなる縦筋Ｒ１の複数の凸状の節Ｇ１がそれぞれ嵌入して位置決めされるので、縦筋取付部１１がその位置で縦筋Ｒ１に固定され、上下に移動してしまうことが防止されるので、天端レベルを精度良く管理することができる。 In the top end level management tool 1 having the above-described configuration, when the top end level management tool body 2 is attached to the longitudinal bars R1 as shown in FIG. Since the plurality of convex nodes G1 of the vertical streak R1 are respectively inserted and positioned, the vertical streak mounting portion 11 is fixed to the vertical streak R1 at that position and is prevented from moving up and down. The top level can be managed with high accuracy.
また、この天端レベル管理具１では、縦筋取付部１１の上側に脱落防止部１２を備えており、縦筋Ｒ１に装着すると、縦筋取付部１１の略Ｃ字状の開口１１ａに向かう脱落防止部１２の左右一対のアーム２１の先端２４が縦筋Ｒ１に対峙する位置にあるので、縦筋Ｒ１は縦筋取付部１１から脱落することが防止される。なお、本実施形態においては、脱落防止部１２と縦筋取付部１１との間に節嵌入部２０を設けているが、図１２に示すように、脱落防止部１２と縦筋取付部１１とを一体とすることも可能である。 Further, this top end level management tool 1 includes a drop prevention portion 12 above the vertical bar attachment portion 11, and when attached to the vertical bar R 1, it heads toward the substantially C-shaped opening 11 a of the vertical bar attachment portion 11. Since the tips 24 of the pair of left and right arms 21 of the drop-off prevention part 12 are in positions where they face the vertical line R1, the vertical line R1 is prevented from falling off the vertical line attachment part 11.
