【０００２】 ［従来の技術］ 宅地造成等における境界壁工事の際使用されている従来の土留め用コンクリー トブロックは、図４に例示するように、隣接する土留め用コンクリートブロック と密着させて連結する鉛直竪板１の下端側に、鉛直竪板１との交角が１０５度位 （俯角１５度位）を保持する傾斜底板２の１端側を連設し、この鉛直竪板１の背 面側に、底辺側が傾斜底板２の上面側に連結する略三角形状の補強リブ３を設け 、この補強リブ３の鉛直竪板１に近接する複数箇所には、隣接する土留め用コン クリートブロックと連結するため鉄筋を通す連結用穴１０を穿設していた。寸法 は、鉛直竪板１が高さ約２ｍ、幅約１ｍ、厚さ約０，６ｍ、傾斜底板が奥行き約 １，３ｍ、厚さ約１ｍであり、総重量は約５トンのコンクリート成形重量物であ る。[Prior Art] A conventional concrete retaining block used for boundary wall construction in a residential land development and the like is closely connected to an adjacent concrete retaining block as shown in FIG. On the lower end side of the vertical vertical plate 1, the one end side of the inclined bottom plate 2 which holds the angle of intersection with the vertical vertical plate 1 of about 105 degrees (depression angle of about 15 degrees) is connected continuously, and the back surface of the vertical vertical plate 1 On the side, a substantially triangular reinforcing rib 3 whose bottom side is connected to the upper surface side of the inclined bottom plate 2 is provided. Adjacent soil retaining concrete blocks are provided at a plurality of positions of the reinforcing rib 3 near the vertical vertical plate 1. For connection, a connecting hole 10 through which a reinforcing bar is inserted is provided. The vertical vertical plate 1 has a height of about 2 m, a width of about 1 m, a thickness of about 0.6 m, an inclined bottom plate has a depth of about 1,3 m and a thickness of about 1 m, and the total weight is about 5 tons of concrete forming weight. It is a thing.
【０００３】 ［考案が解決しょうとする課題］ 土留め用コンクリートブロックは前記の通り寸法及び重量が大きいので、使用 する際は据え付けるための建設用機械を利用するが、作業性の悪い工事現場で図 ５に示すように１個毎に基礎コンクリート５上に鉛直竪板１を載せて位置決めし た後、傾斜底板２を所定角度位置に安定させて据付けるため、傾斜底板２の底面 下の空隙部９に側面から土石等を押し込んで充填し、空隙部９’を残存させずに 定位置に固定する作業は極めて非能率であり、この施工が最も重要であるだけに 据付け作業の能率が著しく低下していた。[Problems to be solved by the invention] Since the concrete block for retaining soil has a large size and weight as described above, a construction machine for installation is used when it is used, but at a construction site where workability is poor. As shown in Fig. 5, after placing and positioning the vertical vertical plates 1 on the foundation concrete 5 one by one, in order to stably install the inclined bottom plate 2 at a predetermined angle position, there is a space below the bottom surface of the inclined bottom plate 2. It is extremely inefficient to push and fill the part 9 with debris, etc. from the side, and to fix it in place without leaving the void 9 '. Since this construction is the most important, the efficiency of the installation work is extremely high. It was falling.
【０００４】 ［課題を解決するための手段］ 本考案に係る土留め用コンクリートブロックは、据え付け工事の際における従 来の問題を解決するために、据え付けた傾斜底板の底面下の空隙部に注入したモ ルタルが容易に入り込むような形状に構成したものである。即ち、側縁を密着し て連結する鉛直竪板の下端に傾斜底板の１端側を連設し、この鉛直竪板の背面側 に、１辺側が鉛直竪板に連結し底辺側が傾斜底板２の上面に連結し、かつ、前記 鉛直竪板の近接箇所に複数の連結用穴を有する略三角形状の補強リブを設けた土 留め用コンクリートブロックにおいて、前記傾斜底板は、隣接する傾斜底板側か らのモルタルが流入し易いように両側縁の下側角部を欠除すると共に、傾斜底板 の底面下の空隙部にモルタルを注入する際、隣接する傾斜底板との間隙から注入 する時は空気抜け穴となり、上面から注入する時は注入穴となる、複数の空気抜 き兼注入穴を穿設したことを特徴とする土留め用コンクリートブロックである。[Means for Solving the Problems] The concrete block for retaining soil according to the present invention is poured into a space below a bottom surface of an installed inclined bottom plate in order to solve a conventional problem during installation work. The shape is designed so that the above-mentioned motor can easily enter. That is, one end side of the inclined bottom plate is connected to the lower end of the vertical vertical plate that closely connects the side edges, and one side is connected to the vertical vertical plate and the bottom side is the inclined bottom plate 2 on the back side of this vertical vertical plate. In the concrete block for earth retaining that is connected to the upper surface of the vertical vertical plate and is provided with a substantially triangular reinforcing rib having a plurality of connecting holes in the vicinity of the vertical vertical plate, the inclined bottom plate is located on the side of the adjacent inclined bottom plate. The lower corners of both side edges are omitted to facilitate the inflow of mortar, and when pouring mortar into the space below the bottom of the inclined bottom plate, when pouring from the gap between the adjacent inclined bottom plates, This is a concrete block for retaining soil, which has a plurality of holes that serve as air vents and holes for pouring when injected from above.

Then, using an appropriate mortar filling machine 6, mortar is injected and fixed in the void space 9 below the bottom surface of the inclined bottom plate 2. At this time, since the lower corners of both side edges are removed from the inclined bottom plate 2 and a plurality of air venting / injection holes 4 are formed, as shown in FIG. 2, there is a gap between the inclined bottom plates 2 adjacent to each other. When injecting mortar from 11, the mortar easily flows in because the corners are cut off, and at the same time, the air bleeding / injection hole 4 serves as an air vent hole in the void 9 under the bottom surface, so mortar inflow is easy. Become. Further, as shown in FIG. 3, when the mortar is injected from the upper side of the inclined bottom plate 2, the air vent / injection hole 4 becomes a mortar injection hole. In this case, since the concrete block for retaining soil has a large weight, it does not move by the mortar injection pressure, and the gap 11 with the adjacent inclined bottom plate 2 and the mortar injected from one air vent / injection hole 4 are The mortar is stably injected into the void portion 9 without overflowing from the air bleeding / injection hole 4 together with the air and leaving the cavity.
【０００６】 ［実施例］ 図１により実施例を説明する。側縁を密着させて隣接する土留め用コンクリー トブロックに連結する鉛直竪板１の下端部と、両側縁の下側角部が欠除され複数 の空気抜き兼注入穴４が穿設された傾斜底板２の１端側を、交角が１０５度位（ 俯角約１５度）に傾斜させて連接し、鉛直竪板１の背面と傾斜底板２の上面に２ 辺側が連結する略三角形状の補強リブ３により構成される。[Embodiment] An embodiment will be described with reference to FIG.
