Description

本発明は主として、建築・土木の分野で使用するセメント系硬化材パネルに関するものであって、特に新素材を使用して薄く成形したセメント系硬化材パネル及びそれを使用した盛土表面の壁面構造に関するものである。   The present invention mainly relates to a cement-based hardened material panel used in the field of construction and civil engineering, and particularly relates to a cement-based hardened material panel formed thinly using a new material and a wall surface structure of a embankment surface using the same. Is.

斜面保護のためなどの盛土構造において、盛土表面を覆う構造としては、盛土の表面に沿ってコンクリートブロックやコンクリートパネルを配置する構造が広く採用されている。
例えば特開２００８−１３３６８２号公報に記載されているように、盛土表面から離れてプレキャストコンクリートパネルを設置し、上下のパネル間に緊張ロッドを貫通させてグラウト材を注入して固定し、背後にはアンカー材を伸ばして、繰り返し盛土するという施工を行うものである。 In the embankment structure for protecting slopes, as a structure covering the embankment surface, a structure in which concrete blocks and concrete panels are arranged along the embankment surface is widely adopted.
For example, as described in Japanese Patent Application Laid-Open No. 2008-133682, a precast concrete panel is installed away from the embankment surface, a tension rod is inserted between the upper and lower panels, and a grout material is injected and fixed. Is a construction where the anchor material is stretched and repeatedly filled.

上記したような盛土構造の施工では、コンクリートブロックやパネルが背後の盛土圧に耐えるための剛構造であるため、極めて厚く、重量の重いものとなり、重機によって運搬・設置を行う必要がある。
また上下のブロックやパネルの連結や、背後の盛土との定着にも煩雑で工程の多い工事が要求される。
このために、従来の剛構造のブロックやパネルの代わりとなる軽量で、人力で運搬・設置が可能であって、施工の容易なパネルが求められていた。 In the construction of the embankment structure as described above, since the concrete block or panel is a rigid structure that can withstand the embankment pressure behind, it is extremely thick and heavy, and needs to be transported and installed by heavy machinery.
In addition, it is complicated and requires a lot of work to connect the upper and lower blocks and panels, and to fix them to the backfill.
For this reason, there has been a demand for a panel that is light in weight, can be transported and installed by human power, and can be easily installed instead of a conventional rigid block or panel.

しかしながら他方、従来のコンクリートパネルは、補強材として内部に鉄筋を配していたが、軽量にするために薄いものとするということは、鉄筋のかぶりも薄くなるということを意味している。
かぶりが薄くなるということは、内部の鉄筋の腐食の危険性が出てくるため、薄くするには限界が生じてくる。
特開２００８−１３３６８２号公報 However, on the other hand, the conventional concrete panel has a reinforcing bar disposed therein as a reinforcing material. However, when it is made thin in order to reduce the weight, it means that the covering of the reinforcing bar is also thinned.
When the cover is thin, there is a risk of corrosion of the internal rebar, so there is a limit to making it thin.
JP 2008-133682 A

以下、図に示す実施例に基づき、本発明を詳細に説明する。
＜１＞ 補強素材
本発明のセメント系硬化材パネル１は、内部に埋設する補強素材２として、多数本の合成樹脂繊維３を絡ませたものを使用する。
使用する合成樹脂としては様々なものが使用できるが、ポリプロピレンなどの熱可塑性樹脂を押し出して、複雑に絡ませたものなどが使用可能である。
絡ませるとは、曲がりくねった繊維同士が複雑・多重に絡み合う状態であり、例えば、乾燥したヘチマの繊維が複雑に絡んでいるような状態と似ている。
合成樹脂繊維としては、数百ミクロンから数ｍｍ程度の太さを有するものが、ある程度の剛性を備えていて、補強素材として好適である。 Hereinafter, the present invention will be described in detail based on the embodiments shown in the drawings.
<1> Reinforcing Material The cement-based hardened material panel 1 of the present invention uses a material in which a large number of synthetic resin fibers 3 are entangled as a reinforcing material 2 embedded therein.
A variety of synthetic resins can be used, and those that are intricately entangled by extruding a thermoplastic resin such as polypropylene can be used.
Entangling is a state in which twisted fibers are entangled in a complex / multiple manner, and is similar to a state in which, for example, dried loofah fibers are entangled in a complex manner.
A synthetic resin fiber having a thickness of about several hundred microns to several mm has a certain degree of rigidity and is suitable as a reinforcing material.

＜２＞ セメント系硬化材
実施例では、セメント系硬化材４としてモルタルを使用するが、セメントミルクやコンクリートも使用可能である。
前記した補強素材２を、型枠５の中に敷き詰める。
補強素材２の厚みは、成形するパネルの厚みよりも若干薄くなっている。
つまりは、型枠５にセメント系硬化材４を充填したとき、パネル１の仕上がり面よりも５〜１０ｍｍ程度低くなるような厚みとしている。
セメント系硬化材４を型枠５に流し込んだ後、テーブルに振動を与えて、合成樹脂繊維の間に硬化材４が密に入り込むようにする。
型枠５としては、底面に凹凸模様などを有する化粧面板を使用することも可能である。
つまりは、型枠５に硬化材４を流しこんだとき、底面側がパネル１の表面側となり、上面側が、パネル１の裏面側となる。
以上のようにして成形した実施例のパネル１は、厚みが１０〜２０ｍｍであって、その平面の縦横の長さは、７００ｍｍ×９００ｍｍである。
以上記載した数値はあくまで例示であって、本発明にかかるセメント系硬化材パネル１は、様々なサイズのパネル１とすることが可能である。 <2> Cement-based hardener In the examples, mortar is used as the cement-based hardener 4, but cement milk or concrete can also be used.
The above-described reinforcing material 2 is spread in the mold 5.
The thickness of the reinforcing material 2 is slightly thinner than the thickness of the panel to be molded.
That is, the thickness is set to be about 5 to 10 mm lower than the finished surface of the panel 1 when the mold 5 is filled with the cement hardening material 4.
After the cement-based hardener 4 is poured into the mold 5, the table is vibrated so that the hardener 4 enters between the synthetic resin fibers densely.
As the formwork 5, it is also possible to use a decorative face plate having an uneven pattern on the bottom surface.
That is, when the hardening material 4 is poured into the mold 5, the bottom side becomes the front side of the panel 1, and the top side becomes the back side of the panel 1.
The panel 1 of the Example shape | molded as mentioned above is 10-20 mm in thickness, The vertical and horizontal length of the plane is 700 mm x 900 mm.
The numerical values described above are merely examples, and the cement-based hardened material panel 1 according to the present invention can be a panel 1 of various sizes.

＜３＞ 補強材料
型枠５に振動を与えた後、未だ乾き切らないセメント系硬化材４の上面、つまりはパネル１としては、盛土側に向く裏面側に、補強材料６を貼付する。
補強材料６としては、不織布、織布、メッシュ布などが使用可能であるが、その他、木板や合成樹脂板なども使用可能である。
実施例では、補強材料６として不織布を使用し、パネル１の上部と下部には別の不織布を貼付している。
下部の補強材料６は、パネル１の上下中間よりも若干上まで貼付し、そこから背面側に補強材料６の一部を長く伸ばして、それを後に述べる控え材７としている。
補強材料６の接着には、硬化材４の接着力でなく、別途接着剤を使用して接着することも可能である。
この補強材料６と控え材７とは、ストック時や運送時に緩衝材の役割も果たすもので、図６に示すように控え材７部分をパネル１に巻きつけるようにする。 <3> Reinforcing Material After the vibration is applied to the mold 5, the reinforcing material 6 is affixed to the upper surface of the cement-based hardened material 4 that has not yet dried, that is, the back surface side facing the embankment side.
As the reinforcing material 6, a non-woven fabric, a woven fabric, a mesh fabric or the like can be used, but a wooden board or a synthetic resin board can also be used.
In the embodiment, a non-woven fabric is used as the reinforcing material 6, and another non-woven fabric is attached to the upper part and the lower part of the panel 1.
The lower reinforcing material 6 is stuck to a position slightly above the middle of the upper and lower sides of the panel 1, and a part of the reinforcing material 6 is extended to the back side from there so as to be a holding material 7 described later.
The reinforcing material 6 can be bonded by using an adhesive instead of the adhesive force of the curing material 4.
The reinforcing material 6 and the retaining material 7 also serve as a cushioning material at the time of stocking or transportation, and the portion of the retaining material 7 is wound around the panel 1 as shown in FIG.

＜４＞ 控え材
控え材７は、盛土の中に伸ばしてパネル１を定着する部材であって、前記したように補強材料６の一部を背面側に伸ばしてもよいが、補強材料６とは別体の部材を使用し、補強材料６の表面に貼付してもよい。
図５に示すように、パネル１内に一端を埋設して、残りを背面側に伸ばしたベルト状の部材も使用可能である。 <4> Retaining Material The reserving material 7 is a member that extends into the embankment and fixes the panel 1, and as described above, a part of the reinforcing material 6 may be extended to the back side. May be attached to the surface of the reinforcing material 6 using a separate member.
As shown in FIG. 5, it is also possible to use a belt-like member in which one end is embedded in the panel 1 and the rest is extended to the back side.

＜５＞ 盛土表面
以上のようなセメント系硬化材パネル１を使用して、盛土表面に壁面構造を構築する場合について説明する。
１０ｃｍ程度の間隔ごとに鉄筋８を縦横に配することによって網状に組んで、それをＬ形に屈曲した鋼製壁面枠９を設置し、その背後に盛土１０を盛る。
しかしながら、鉄筋８の間隔が比較的大きいため、鋼製壁面枠９の起立した面３０ｃｍと底面側の奥行き５０ｃｍを覆い、更に盛土１０したときにその上面の奥行き５０ｃｍ程度とを、断面コ字状に覆う内壁シート１６を配してある。
実施例では、内壁シート１６として不織布を使用している。
その盛土１０の上に鋼製壁面枠９を設置し、その背後に更に盛土１０する。 <5> Embankment surface The case where a wall surface structure is constructed on the embankment surface using the cement-based hardener panel 1 as described above will be described.
A steel wall frame 9 in which the reinforcing bars 8 are arranged in a net-like manner at intervals of about 10 cm and are bent in an L shape is installed, and the embankment 10 is placed behind the steel wall frame 9.
However, since the interval between the reinforcing bars 8 is relatively large, the steel wall frame 9 is covered with the standing surface 30 cm and the bottom side depth 50 cm, and when the bank 10 is further filled, the upper surface has a depth of about 50 cm. An inner wall sheet 16 is provided to cover the inner wall.
In the embodiment, a nonwoven fabric is used as the inner wall sheet 16.
A steel wall frame 9 is installed on the embankment 10, and the embankment 10 is further placed behind it.

＜６＞ 通り調整材
鋼製壁面枠９の上端部に、水平に通り調整材１１を取り付ける。
通り調整材１１は断面Ｌ形の部材であって、水平面とその盛土表面側に下方に垂下する面とから成っている。
この通り調整材１１の幅方向に長い長孔１３に、鋼製壁面枠９の鉄筋８に繋いだ寸切りボルト１４を通し、その螺合したナット１５・１５によって通り調整材１１を上下から挟んで固定してある。
場合によっては、鋼製壁面枠９の鉄筋８のうち、一部の幾本かを他の鉄筋８よりも上方に突出させ、その突出させた鉄筋８の周囲にネジ切りを施し、それを寸切りボルト代わりに使用して通り調整材１１の長孔１３に通し、鉄筋８に螺合したナット１５・１５によって通り調整材１１を上下から挟んで固定することも考えられる。 <6> Street adjustment material The adjustment material 11 is attached to the upper end of the steel wall frame 9 horizontally.
The street adjuster 11 is a member having an L-shaped cross section, and includes a horizontal surface and a surface that hangs downward on the embankment surface side.
In this manner, a slitting bolt 14 connected to the reinforcing bar 8 of the steel wall frame 9 is passed through the long hole 13 which is long in the width direction of the adjusting material 11, and the adjusting material 11 is sandwiched from above and below by the screwed nuts 15 and 15. It is fixed with.
In some cases, some of the reinforcing bars 8 of the steel wall frame 9 are protruded upward from the other reinforcing bars 8, and threading is performed around the protruding reinforcing bars 8. It is also conceivable to use the nuts 15 and 15 screwed to the reinforcing bars 8 so as to sandwich the adjusting material 11 from above and below by using it instead of the cutting bolt and passing it through the long hole 13 of the adjusting material 11.

＜７＞ パネルの設置
セメント系硬化材パネル１の背面側を、通り調整材１１の表面側に接し、控え材７を通り調整材１１の水平面と同じ高さに維持した状態で、背後の盛土１０の上に敷き伸ばす。
控え材７の上に土砂を載せて押えるなり、盛土１０して押え、パネル１を定着する。 <7> Panel installation The back side of the cement-based hardened material panel 1 is in contact with the surface side of the adjustment material 11, and the back embankment is maintained in the state where it passes through the backing material 7 and is maintained at the same height as the horizontal surface of the adjustment material 11. Spread on top of 10.
The earth and sand are placed on the retentive material 7 and pressed. The bank 10 is pressed and the panel 1 is fixed.

＜８＞ パネルの積み上げ
下段のパネル１の設置の後、前記した鋼製壁面枠９の設置、盛土１０を繰り返し、適宜位置に通り調整材１１を取り付ける。
前記した手順で、再びパネル１の設置・定着を行うが、上段となるパネル１の下端部は、下段のパネル１の表面側上端部と重なるようにする。
このように上段のパネル１と下段のパネル１とを重ねることで、ヨロイ壁のような趣をかもし出すとともに、上段のパネル１の下端面と下段のパネル１の上端面とを突き合わせるという施工の困難性を回避できる。
また、背後の盛土が経年変化によって沈下したとき、上段と下段のパネル１の重なり代によって沈下量を吸収でき、外観が悪くならないという効果も得られる。 <8> Stacking of panels After the installation of the lower panel 1, the installation of the steel wall frame 9 and the embankment 10 are repeated, and the adjustment material 11 is attached to the appropriate position.
The panel 1 is again installed and fixed in the above-described procedure, but the lower end portion of the upper panel 1 is overlapped with the upper end portion on the surface side of the lower panel 1.
In this way, the upper panel 1 and the lower panel 1 are overlapped to bring out a taste like an armored wall, and the lower end surface of the upper panel 1 and the upper end surface of the lower panel 1 are butted together. Difficulty can be avoided.
In addition, when the back embankment sinks due to secular change, the amount of settlement can be absorbed by the overlap margin of the upper and lower panels 1, and the appearance is not deteriorated.

＜９＞ 盛土補強材
図において１２は、ジオテキスタイルなどの盛土補強材であって、盛土の適宜位置に挟み込んでいる。 <9> Embankment reinforcement material In the figure, 12 is an embankment reinforcement material such as geotextile, and is sandwiched between appropriate positions of the embankment.

図５に示すのは控え材１１の他の実施例であって、パネル１内に一端を埋設して、残りを背面側に伸ばしたベルト状の部材である。   FIG. 5 shows another embodiment of the retainer 11, which is a belt-like member in which one end is embedded in the panel 1 and the rest is extended to the back side.
