Description
この発明は、従来のコンクリート擁壁の代わりに用いる土留擁壁で、一般的には傾斜地に宅地造成を行う場合、或いは道路などを作る場合に地盤高さの調整に用いられるコンクリート壁に関するものである。 The present invention relates to a retaining wall used in place of a conventional concrete retaining wall, and generally relates to a concrete wall used for adjusting the ground height when building a residential land on an inclined land or when creating a road or the like. is there.
従来の土留擁壁は、例えば図21のような構造が一般的で、たて壁7、かかと版8、つま先版9から成り、地盤が悪い場合は杭10で壁を支持する方法がとられていた。 For example, a conventional retaining wall has a structure as shown in FIG. 21 and is composed of a vertical wall 7, a heel plate 8, and a toe plate 9. When the ground is bad, a method of supporting the wall with a pile 10 is used. It was.
このような構造物を作るには、現場において土砂の掘削、整地、くい打ち、均しコンクリートの打設、型枠組立て、配筋、躯体コンクリートの打設、型枠の取り外し等多くの工程と手順を踏んでようやく出来上がる。 In order to make such a structure, there are many processes such as excavation of earth and sand, leveling, pile driving, placing of leveled concrete, formwork assembly, bar arrangement, placing of concrete, and removal of formwork. The steps are finally completed.
また、その後にも、かかと版のうしろに土砂の埋戻しを何層にも分けて転圧しながら行うのが一般的であり、多くの人手と長期にわたる工期、高い費用を要していた。
したがって、いままでに各コンクリート製品メーカーも研究を重ね、擁壁そのものの製品化には成功し、市場に出廻っているが、くいが必要な地盤の擁壁では根本的な工期、費用の縮減には至ってない。
なお、これらの問題点を箇条書に整理すると次のようになる。
(イ)工事期間つまり施工に要する期間は、従来工法では最低でも40日程度必要とした。
(ロ)通常、地盤が軟弱で沈下の恐れがある場合には、従来の土留め擁壁を示す図21で説明すると、たて壁7およびかかと版8、つま先版9と上に乗る土の重量を杭10で支えるように設計していたため、たて壁7の重量を支えるだけの杭より4〜5倍の重量を支えていた。
(ハ)本来の土留壁のみであれば必要な用地幅は壁厚さだけでいいが、かかと版8とつま先9の幅の用地が必要であった
(ニ)土留壁が不要となり撤去したい時には、従来は土を掘り返して擁壁を破砕し、産業廃棄物として処分するのが実情であった。
本発明は、従来の問題点を解決し且つ発明の目的を達成するために提供するものである。
Therefore, each concrete product maker has been researching so far and has succeeded in commercializing the retaining wall itself, and it is on the market. However, in the retaining wall of the ground that requires piles, the fundamental construction period and cost reduction It has not reached.
In addition, these problems are organized into bullets as follows.
(B) The construction period, that is, the period required for construction, is at least about 40 days in the conventional construction method.
(B) Normally, when the ground is soft and there is a risk of subsidence, it will be explained with reference to FIG. 21 showing a conventional retaining wall. The vertical wall 7 and the heel plate 8, the toe plate 9 and the soil on the top Since the weight was designed to be supported by the pile 10, it supported 4 to 5 times the weight of the pile that only supported the weight of the vertical wall 7.
(C) If only the original retaining wall is required, the necessary land width is only the wall thickness, but a site with the width of the heel plate 8 and toe 9 was necessary. (D) When the retaining wall is no longer needed and you want to remove it. In the past, the actual situation was to dig up the soil, crush the retaining wall, and dispose of it as industrial waste.
The present invention is provided to solve the conventional problems and achieve the object of the invention.
本発明の第1はコンクリート壁において、縦長で長方形を成すコンクリート壁体の片面にH型鋼製杭体のフランジの片方を当該フランジ頭頂部をコンクリート壁体頂部より少し低い位置で埋め込んで一体にすると共に、下部をコンクリート壁体の下辺より延長させ、当該コンクリート壁体とH型鋼製杭体とで合成構造にし、コンクリート壁体の両側端辺に目地を設けたものである。 In the first concrete wall of the present invention, the flange of one of the H-type steel pile body on one side of the concrete wall forming a rectangle together embed the flange top portion at a position slightly lower than a concrete wall top in portrait In addition, the lower part is extended from the lower side of the concrete wall body, a composite structure is formed by the concrete wall body and the H-shaped steel pile body, and joints are provided on both side edges of the concrete wall body.
本発明の第2はコンクリート壁において、内部に鉄筋を設けてあるコンクリート壁体の片面に型鋼製杭体又は円柱形の鋼製杭体に一体に設けた棒状の掛止部材を埋め込んで鉄筋に接合して一体とし、型鋼製杭体又は円柱形の杭体の頭頂部をコンクリート壁体頂部より少し低い位置にして一体にすると共に、下部をコンクリート壁体の下辺より延長させ、コンクリート壁体の両側端辺に目地を設け、且つ、コンクリート壁体と当該杭体との合成構造にしたものである。
The second aspect of the present invention is a concrete wall, in which a reinforcing bar is embedded by embedding a rod-shaped hook member integrally provided in a steel pile body or a cylindrical steel pile body on one side of a concrete wall body in which a reinforcing bar is provided. To make the steel steel pile or columnar pile heads a little lower than the top of the concrete wall body, and extend the lower part from the lower side of the concrete wall body. Joints are provided on both side edges of the body, and a composite structure of the concrete wall body and the pile body is provided.
本発明の効果を次の通りである。
(イ)工事期間つまり、施工時間は従来の方法に比べて約2分の1から3分の1で済む。
(ロ)土の重量を支えるための杭の必要がないので構造的な無駄がない。
(ハ)壁の厚さ程度の用地しか必要としないため用地費用の節約および用地の有効活用が可能である。
(ニ)壁を設置後、壁が不要となった場合には、引き抜くことが可能であり、壁を壊さないで何回でも使用できるため、仮設土留壁としても利用できる。
(ホ)構造全体が省資源であり、経済的である。
The effects of the present invention are as follows.
(B) The construction period, that is, the construction time is about one-half to one-third compared with the conventional method.
(B) There is no structural waste because there is no need for piles to support the weight of the soil.
(C) Since only a site with a wall thickness is required, the site cost can be saved and the site can be used effectively.
(D) When the wall is no longer needed after the wall has been installed, it can be pulled out and used as many times without breaking the wall, so it can also be used as a temporary earth retaining wall.
(E) The entire structure is resource-saving and economical.
コンクリート壁体にH形鋼の一部を埋込んで一体とし、コンクリート壁の両側端に凹溝形又は凸溝形の目地を設けたものであり、また、コンクリート壁体にH形鋼を掛止部材により接合して一体とし、コンクリート壁体の両側端辺に沿って目地を設けた構造とする。 Part of the H-shaped steel is embedded in the concrete wall and integrated, and both sides of the concrete wall are provided with concave or convex joints, and the H-shaped steel is hung on the concrete wall.

「具体的な施工例」
次に本発明の施工例を説明する。
(1) 図22の杭打ち機MのクランプCで図1に示すH型鋼製杭体2又はコンクリート壁体1の上部を掴持して吊り上げる。
(2) 設定の杭打ち地点においてコンクリート壁体1を下降させて杭体2の下端・コンクリート壁体1の下端の順に地中に所定の深さまで打ち込む。
(3) 同様に次のコンクリート壁体を吊り上げ、先に打ち込んだコンクリート壁体1の隣に並べてその凸溝形目地3に沿って吊り上げたコンクリート壁体1の凹溝形目地4を合わせながら下降させて先端から地中に所定の深さまで打ち込む。
(4) 以上のように、前記(1)〜(3)の工程を順次くり返していくことにより図3に示すような連続した壁が出来上がる。
"Specific construction examples"
Next, a construction example of the present invention will be described.
(1) The upper part of the H-shaped steel pile body 2 or the concrete wall body 1 shown in FIG. 1 is held and lifted by the clamp C of the pile driving machine M in FIG.
(2) The concrete wall 1 is lowered at the set pile driving point and driven into the ground to a predetermined depth in the order of the lower end of the pile body 2 and the lower end of the concrete wall body 1.
(3) Similarly, the next concrete wall is lifted, and it is placed next to the concrete wall 1 that has been driven in first, and lowered along with the grooved joint 4 of the concrete wall 1 lifted along the grooved joint 3. And drive it from the tip into the ground to a certain depth.
(4) As described above, a continuous wall as shown in FIG. 3 is completed by repeating the steps (1) to (3) in sequence.
次に産業上の利用可能性を述べると、一般的に土留擁壁は、地盤の段差を安定した状態に保つための構造である。
重量を支えるための構造ではないことを念頭に置き、土の水平方向の力を受け止め、その力を地中の下部に伝えるためだけの壁を設けることとし、強度的に十分な耐力を合理的に支える構造として、コンクリート壁と形鋼の合成構造を発明した。
なお、この構造は、従来の鉄筋コンクリート壁とは鋼材の用い方において発想が根本的に異なることを付言する。
Next, the industrial applicability will be described. Generally, the retaining wall is a structure for maintaining the level difference of the ground in a stable state.
Keeping in mind that it is not a structure to support the weight, we decided to provide a wall that only receives the force in the horizontal direction of the soil and transmits the force to the lower part of the ground, and rationally provides sufficient strength We invented a composite structure of concrete walls and shaped steel as a structure to support.
Note that this structure is fundamentally different from the conventional reinforced concrete wall in the way the steel is used.
