Description
【０００１】
【発明の属する技術分野】
本発明は、橋脚、砂防ダム、護岸壁その他各種コンクリート構造物の磨耗や損傷を防止するためにその表面に取り付ける保護材の取り付け方法に関する。
【０００２】
【従来の技術】
各種コンクリート構造物の表面の保護工としてゴムや合成樹脂等の弾性材による板状の保護材をビルトイン状態で取り付けることが従来から行われておりその取り付け方法を図５、図６を用いて以下に説明する。
図６において、１は耐磨耗性や耐衝撃性等使用目的に応じた特性を有するゴムや合成樹脂等の弾性材製の保護材であり、コンクリートの打設によって構築される構造物２の所望個所に取り付けられている。図５において、３はその構造物２を構築するための型枠、４は構造物の所望個所に取り付ける保護材１と同形の型枠である。
【０００３】
そこで、構造物２に保護材１を取り付けるには、図５に示す如く、型枠３の内側にアンカーソケット５を仮付けした保護材用の型枠４を取り付けた状態で設置し、型枠３の内側にコンクリート打設養生後、型枠３および型枠４を外し、その型枠４の個所に図６に示す如く保護材１を嵌めてコンクリート面と保護材面とを同一面状態にしてアンカーソケット５にボルト６で固定するものである。
【０００４】
【発明が解決しようとする課題】
このような従来技術によると、保護材を設置するために、型枠にアンカーソケットを仮付けした保護材用の型枠を取り付けて一体に構成しなければならず、しかも、コンクリート打設養生後に保護材用の型枠を外し、その個所に保護材を嵌めるという作業が要求され、しかもその際に、保護材用の型枠と保護材の大きさやアンカーソケットの位置の誤差等が設置時に困難な条件となる等の問題がある。
【０００５】
【課題を解決するための手段】
そこで本発明は、型枠の内側に予め保護材を合わせた状態にして型枠を設置し、コンクリートの打設養生後に型枠を取り除くことにより、構造物のコンクリート表面に保護材が残るようにしたことを特徴とする。
【０００６】
【発明の実施の形態】
以下に本発明の実施の形態を図面を用いて説明する。
第１形態例
構造物７を構築するための型枠８を、その内側の所望個所に保護材９を抱き合わせボルト１０とアンカーソケット１１で挟んで一体にした状態で設置する。
【０００７】
なお、必要に応じて、破損防止材１２を取り付けておく。
そこで、コンクリートを打設養生後抱き合わせボルト１０を外して型枠８を取り外し、保護材９をボルト１３によって固定するものである。
このようにして構造物７に保護材９を取り付けることにより、保護材９はコンクリートと同一面状に正確に取り付けられることになり、しかも取り付け作業に手間取ることもない。
【０００８】
第２形態例
保護材９に予めアンカーソケット１１をボルト１３によって締め付けて一体としておき、このようにした保護材９を構造物７を構築するための型枠８の内側の所望個所に配置し、型枠８と保護材９を一緒に挟むように倒れ込み防止の押さえ治具１４で支えて設置し、コンクリートを打設する。
【０００９】
コンクリートの養生後外側の押さえ治具１４を外して型枠８を取り除くことにより、そのままで保護材９は構造物７のコンクリート面と同一面状に正確に取り付けられることになる。
【００１０】
【発明の効果】
以上詳細に説明した本発明によると、型枠の内側に予め保護材を合わせた状態にして型枠を設置し、コンクリートの打設養生後に型枠を取り除くことにより、構造物のコンクリート表面に保護材が残るようにしたことにより、保護材はコンクリート表面と同一面状に確実にビルトイン状態で取り付けることができる効果を有し、しかも、保護材は予め型枠と共に設置してコンクリートを打設するために、保護材は後付けとは異なり取り付け作業に手間取ることもなく、正確に設置することができる効果を有する。
【００１１】
また、予め保護材にアンカーソケットを一体にしておくと、アンカーソケットはコンクリート打設時に固定され、それによって保護材も容易に構造物に固定することができる効果を有する。

BACKGROUND OF THE INVENTION
The present invention relates to a method for attaching a protective material to be attached to a surface of a bridge pier, a sabo dam, a revetment wall, or other various concrete structures in order to prevent wear or damage.
[0002]
[Prior art]
A plate-shaped protective material made of an elastic material such as rubber or synthetic resin has been conventionally attached as a protective work for the surface of various concrete structures, and the attachment method is described below with reference to FIGS. Explained.
In FIG. 6, reference numeral 1 denotes a protective material made of an elastic material such as rubber or synthetic resin having characteristics according to the purpose of use, such as wear resistance and impact resistance, and is a structure 2 constructed by placing concrete. It is attached at the desired location. In FIG. 5, 3 is a formwork for constructing the structure 2, and 4 is a formwork of the same shape as the protective material 1 attached to a desired location of the structure.
[0003]
Therefore, in order to attach the protective material 1 to the structure 2, as shown in FIG. 5, the protective material 1 is installed in a state where the protective material mold 4 with the anchor socket 5 temporarily attached is attached inside the mold 3. 3, after the concrete is placed and cured, the mold 3 and the mold 4 are removed, and the protective material 1 is fitted to the mold 4 as shown in FIG. The anchor socket 5 is fixed with bolts 6.
[0004]
[Problems to be solved by the invention]
According to such a conventional technique, in order to install the protective material, it is necessary to attach and form a protective material mold temporarily attached with an anchor socket to the mold, and after the concrete placement curing. It is required to remove the protective material formwork and fit the protective material at the location, and at that time, it is difficult to install the protective material form and the size of the protective material and the position of the anchor socket. There are problems such as becoming a necessary condition.
[0005]
[Means for Solving the Problems]
Therefore, the present invention is such that the protective material is left on the concrete surface of the structure by installing the mold with the protective material in advance inside the mold and removing the mold after curing the concrete. It is characterized by that.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
A mold 8 for constructing the first embodiment structure 7 is installed in a state in which the protective material 9 is sandwiched between the bolts 10 and the anchor sockets 11 at a desired location inside thereof and integrated.
[0007]
In addition, the damage prevention material 12 is attached as needed.
Therefore, after the concrete is placed and cured, the tie bolts 10 are removed, the mold 8 is removed, and the protective material 9 is fixed by the bolts 13.
By attaching the protective material 9 to the structure 7 in this way, the protective material 9 can be accurately attached to the same surface as the concrete, and it does not take time for the attachment work.
[0008]
The anchor socket 11 is previously fastened to the second embodiment protective material 9 with bolts 13 so as to be integrated, and the protective material 9 thus constructed is arranged at a desired location inside the mold 8 for constructing the structure 7, The mold 8 and the protective material 9 are supported and installed by a holding jig 14 for preventing falling down, and concrete is placed.
[0009]
By removing the outer pressing jig 14 after curing the concrete and removing the mold 8, the protective material 9 can be accurately attached to the concrete surface of the structure 7 as it is.
[0010]
【The invention's effect】
According to the present invention described in detail above, the formwork is placed with the protective material in advance inside the formwork, and the concrete surface of the structure is protected by removing the formwork after the concrete is placed and cured. By making the material remain, the protective material has the effect that it can be securely mounted in the same plane as the concrete surface in a built-in state, and the protective material is installed together with the formwork in advance to place the concrete. Therefore, unlike the retrofitting, the protective material has an effect that it can be accurately installed without taking time for the mounting work.
[0011]
In addition, when the anchor socket is integrated with the protective material in advance, the anchor socket is fixed when the concrete is placed, whereby the protective material can be easily fixed to the structure.
