Description

本発明は、コンクリート躯体の養生方法及びその装置に関するものである。   The present invention relates to a method for curing a concrete frame and an apparatus therefor.

一般に柱や壁等のコンクリート躯体を構築する際には、生コンクリートを打設するために型枠を用いており、型枠を組み立てる際には、図１０に示す如く型枠固定用ロッド１と型枠固定具２とを用いて左右の型枠３，３を固定している。   In general, when building a concrete frame such as a column or wall, a formwork is used for placing ready-mixed concrete. When assembling a formwork, as shown in FIG. The left and right mold frames 3 and 3 are fixed by using the mold fixture 2.

型枠固定用ロッド１は、構築するコンクリート躯体の厚さ寸法に応じた長さのものを選定して用いられ、型枠固定用ロッド１の両側には、雄ネジ部４が形成されている。また型枠固定具２は、図１１に示す如く型枠位置決め駒５と、締付ロッド６と、押し具７と、締付ナット８により構成されている。   The mold fixing rod 1 has a length corresponding to the thickness dimension of the concrete frame to be constructed and is used, and male screw parts 4 are formed on both sides of the mold fixing rod 1. . Further, as shown in FIG. 11, the mold fixture 2 includes a mold positioning piece 5, a clamping rod 6, a pusher 7, and a clamping nut 8.

前記型枠位置決め駒５は、前記型枠固定用ロッド１の雄ネジ部４に螺合する雌ネジ部９が一端に開口したナット１０を有している。該ナット１０の外周には、雌ネジ部９の開口側の外径が小さく開口と反対側に向かって大径となる截頭円錐形状の位置決め部材１１が一体に固定されており、更に、位置決め部材１１の中心部には、前記雌ネジ部９の開口と反対側に向かって所要の長さで延設されたボルト部１２を備えている。また前記型枠位置決め駒５の位置決め部材１１は、一般に合成樹脂にて截頭円錐形の筒状に形成されており、更に、その他の部材は鋼等の金属で形成されている。   The formwork positioning piece 5 has a nut 10 having a female screw part 9 screwed into the male screw part 4 of the formwork fixing rod 1 opened at one end. On the outer periphery of the nut 10, a frustoconical positioning member 11 having a small outer diameter on the opening side of the female screw portion 9 and a larger diameter toward the opposite side of the opening is integrally fixed. At the center of the member 11, there is provided a bolt portion 12 extending in a required length toward the side opposite to the opening of the female screw portion 9. In addition, the positioning member 11 of the mold positioning piece 5 is generally formed of a synthetic resin in the shape of a truncated cone, and the other members are formed of metal such as steel.

前記締付ロッド６は、前記型枠位置決め駒５のボルト部１２に螺合する雌ネジ部１３を一端に有しており、また締付ロッド６の他端には所要長さの雄ネジ部１４が形成されている。また前記押し具７は、開口１５を介して前記締付ロッド６に嵌合し、更に図１０に示すように型枠３の外面を押圧して支持するための二本のパイプ材１６を支持するようにした凹部１７を両側に備えている。更に前記締付ナット８は、前記締付ロッド６の雄ネジ部１４に螺合して前記押し具７を押圧するようにしている。   The clamping rod 6 has a female screw portion 13 that is screwed into the bolt portion 12 of the mold positioning piece 5 at one end, and a male screw portion of a required length at the other end of the clamping rod 6. 14 is formed. The pusher 7 is fitted into the clamping rod 6 through the opening 15 and further supports two pipe members 16 for pressing and supporting the outer surface of the mold 3 as shown in FIG. A concave portion 17 is provided on both sides. Further, the tightening nut 8 is screwed into the male thread portion 14 of the tightening rod 6 to press the pusher 7.

型枠３，３を組み立てて生コンクリートを打設する際には、先ず、構築する柱や壁等の厚さ寸法に応じた長さの型枠固定用ロッド１を用意する。この時、型枠固定用ロッド１の両端の雄ネジ部４には、型枠位置決め駒５の雌ネジ部９が螺合して取り付けられており、型枠位置決め駒５の位置決め部材１１の大径側端部の相互間距離Ｓが、構築するコンクリート躯体の厚さとなるので、型枠位置決め駒５のねじ込みにより距離Ｓを調整する。   When assembling the molds 3 and 3 and placing the ready-mixed concrete, first, the mold fixing rod 1 having a length corresponding to the thickness dimension of the pillar or wall to be constructed is prepared. At this time, the female screw portions 9 of the mold positioning piece 5 are screwed onto the male screw portions 4 at both ends of the mold fixing rod 1, and the positioning member 11 of the mold positioning piece 5 is large. Since the distance S between the radial side ends is the thickness of the concrete frame to be constructed, the distance S is adjusted by screwing the formwork positioning piece 5.

左右の型枠３，３に予め所要の間隔で形成されている開口３ａに、型枠固定用ロッド１の両端に備えた型枠位置決め駒５のボルト部１２を貫通させる。そして、型枠３，３を貫通したボルト部１２の先端に、前記締付ロッド６の雌ネジ部１３を螺合し、型枠位置決め駒５と締付ロッド６により型枠３，３を挾持する。   Bolt portions 12 of the mold positioning piece 5 provided at both ends of the mold fixing rod 1 are passed through openings 3a formed in the left and right molds 3 and 3 at a predetermined interval in advance. Then, the female thread portion 13 of the clamping rod 6 is screwed to the tip of the bolt portion 12 that penetrates the mold frames 3, 3, and the mold frames 3, 3 are held by the mold positioning piece 5 and the clamping rod 6. To do.

次に、型枠３，３の外面に二本のパイプ材１６を当て、このパイプ材１６を外側から押すように押し具７を当てて締付ロッド６の雄ネジ部１４に螺合した締付ナット８を締込むようにする。すると、押し具７及びパイプ材１６を介して型枠３，３は外側に湾曲しないようにしっかり支持される。型枠３，３は、所要の間隔で形成されている複数の開口３ａにおいて、前記型枠固定用ロッド１と型枠固定具２とにより連結され、これにより型枠３，３は、距離Ｓの間隔を保持した状態で高い強度に組立てられる。   Next, two pipe members 16 are applied to the outer surfaces of the molds 3 and 3, and the pressing member 7 is applied so as to press the pipe members 16 from the outside and screwed into the male thread portion 14 of the tightening rod 6. The attached nut 8 is tightened. Then, the molds 3 and 3 are firmly supported via the pusher 7 and the pipe material 16 so as not to be bent outward. The molds 3 and 3 are connected to each other by the mold fixing rod 1 and the mold fixture 2 at a plurality of openings 3a formed at a predetermined interval. It is assembled with high strength while maintaining the interval of.

このように組み立てられた型枠３，３間に生コンクリートを打設する。   Fresh concrete is placed between the molds 3 and 3 assembled in this way.

続いて、生コンクリートの打設後、所要の固化時間を経過した後に前記型枠３，３を除去する際には、先ず、締付ナット８を緩めて押し具７を緩めることにより二本のパイプ材１６を取り外した後、締付ロッド６を回して型枠位置決め駒５のボルト部１２から締付ロッド６を取り外し、続いて、型枠３，３をボルト部１２から抜き出して型枠３を取り外す。   Subsequently, when removing the molds 3 and 3 after the required solidification time has elapsed after placing the ready-mixed concrete, first, the fastening nut 8 is loosened and the pusher 7 is loosened to remove the two pieces. After removing the pipe material 16, the clamping rod 6 is turned to remove the clamping rod 6 from the bolt part 12 of the mold positioning piece 5, and then the molds 3 and 3 are extracted from the bolt part 12 to form the mold 3. Remove.

次に、ボルト部１２を指で掴んで回すか、又は型枠位置決め駒５の内側のナット１０に工具を係合させて回すことにより、型枠位置決め駒５を型枠固定用ロッド１の雄ネジ部４から取り外す。   Next, the bolt 12 is grasped with a finger and turned, or the tool is engaged with the nut 10 inside the mold positioning piece 5 and turned to turn the mold positioning piece 5 into the male part of the mold fixing rod 1. Remove from the screw part 4.

この時、コンクリート躯体１８の表面には、図１２に示す如く前記型枠位置決め駒５による截頭円錐形の凹部１９が所要の間隔で形成されており、更に各凹部１９には、前記型枠固定用ロッド１の雄ネジ部４が所要の長さで突出している。   At this time, as shown in FIG. 12, truncated conical recesses 19 are formed on the surface of the concrete casing 18 by the mold positioning piece 5 at a predetermined interval. The male screw portion 4 of the fixing rod 1 protrudes with a required length.

その後、コンクリート躯体１８をビニールシート（図示せず）で囲んで養生し、コンクリート躯体１８の内部や外面で適切に凝結が進むようにしている。   After that, the concrete case 18 is surrounded by a vinyl sheet (not shown) and cured so that the congealing proceeds appropriately inside and outside the concrete case 18.

尚、コンクリート躯体を養生する技術としては、生コンクリートの打設前に型枠の内面に予めコンクリート養生保持板を配置し、養生時に、コンクリート躯体の表面に接触するコンクリート養生保持板を連続的に用いてコンクリート躯体を養生するものがある（例えば、特許文献１参照）。   In addition, as a technology for curing the concrete frame, a concrete curing holding plate is placed in advance on the inner surface of the formwork before placing the ready-mixed concrete, and the concrete curing holding plate that is in contact with the surface of the concrete frame during curing is continuously applied. Some use it to cure concrete frames (see, for example, Patent Document 1).

しかしながら、コンクリート躯体１８をビニールシートで囲んで養生する際には、コンクリート躯体１８とビニールシートとの接触面や隙間に結露を生じ、結露等の空気中の汚れがコンクリート躯体１８の表面に付着するという問題があった。またビニールシートで囲んだコンクリート躯体１８に対して機材や資材が接触した場合には、コンクリート躯体１８の表面に凹みや欠損を生じてコンクリート躯体１８の表面を適切に保護できないという問題があった。更に特許文献１の如くコンクリート養生保持板を用いる場合には、養生時であってもコンクリート養生保持板がコンクリート躯体１８の表面に常に接触するため、乾燥養生を適切に行うことができず、また型枠３，３を外した後であってもコンクリート躯体１８の表面状態を確認することできないという問題があった。   However, when the concrete casing 18 is cured by being surrounded by a vinyl sheet, condensation occurs on the contact surface or gap between the concrete casing 18 and the vinyl sheet, and dirt in the air such as condensation adheres to the surface of the concrete casing 18. There was a problem. In addition, when equipment or materials come into contact with the concrete housing 18 surrounded by the vinyl sheet, there is a problem that the surface of the concrete housing 18 cannot be properly protected due to the formation of a dent or a defect on the surface of the concrete housing 18. Further, when a concrete curing holding plate is used as in Patent Document 1, since the concrete curing holding plate is always in contact with the surface of the concrete frame 18 even during curing, drying curing cannot be performed properly, and Even after the molds 3 and 3 are removed, there is a problem that the surface state of the concrete housing 18 cannot be confirmed.

本発明は、斯かる実情に鑑み、コンクリート躯体の表面に結露等の汚れが付着することを抑制して表面の仕上げ状態を良好にし、且つコンクリート表面を適切に保護するコンクリート躯体の養生方法及びその装置を提供しようとするものである。   In view of such circumstances, the present invention suppresses the adhesion of dirt such as dew condensation on the surface of the concrete frame to improve the surface finish state, and appropriately protects the concrete surface. The device is to be provided.

It is possible to appropriately protect the surface of the frame and improve the finish state of the surface of the concrete frame. Furthermore, since the plate part is arranged through the support tube after removing the formwork, the plate part is not brought into contact with the concrete case, and the concrete case can be properly dried and cured. When it is done, the surface state of the concrete frame can be confirmed, and an excellent effect that the finished state of the surface can be improved can be achieved.
