図を参照して本発明に実施形態を説明する。   Embodiments will be described with reference to the drawings.

図１は実施形態１に係る壁体構成部材１００を示し、溝形鋼矢板からなる壁体構成用本体部材１と、これに溶接接合される支持力増強用形鋼２から構成される。支持力増強用形鋼２は、所定長のＨ形鋼で構成されている。また、壁体構成用本体部材１の長手方向と直交する方向の断面形状と、支持力増強用形鋼２の長手方向と直交する方向の断面形状は、壁体構成部材１００を鉛直方向に見たとき互いに重なり合わないようにして溶接等の手段で接合される。   FIG. 1 shows a wall constituting member 100 according to the first embodiment, and is constituted by a wall constituting main body member 1 made of a grooved steel sheet pile and a supporting force enhancing shape steel 2 welded and joined thereto. The supporting force enhancing section steel 2 is composed of a predetermined length of H-section steel. Moreover, the cross-sectional shape in the direction orthogonal to the longitudinal direction of the wall-body-constituting main body member 1 and the cross-sectional shape in the direction orthogonal to the longitudinal direction of the support-strengthening structural steel 2 are such that the wall-body constituting member 100 is viewed in the vertical direction. Then, they are joined by means such as welding so as not to overlap each other.

さらに説明すると、Ｕ形鋼矢板からなる壁体構成用本体部材１と、そのウエブ７の両面に溶接接合されるＨ形鋼で構成される支持力増強用形鋼２の両部材において、支持力増強用形鋼２を壁体構成用本体部材１の全長にわたって溶接接合してもよいが、両部材のうち、Ｕ形鋼矢板からなる壁体構成用本体部材１が地盤への打ち込み時に上側になり、Ｈ形鋼からなる支持力増強用形鋼２が下側になるようにし、かつ一部が重なり合い、その重なり部を溶接するように構成してもよい。   More specifically, in both members of the wall-constituting main body member 1 made of a U-shaped steel sheet pile and the H-shaped steel 2 made of H-shaped steel welded to both surfaces of the web 7, The reinforcing structural steel 2 may be welded over the entire length of the wall constituting main body member 1, but the wall constituting main body member 1 made of a U-shaped steel sheet pile is on the upper side when driven into the ground. Therefore, it may be configured such that the supporting force enhancing structural steel 2 made of H-shaped steel is on the lower side, and a part thereof overlaps and the overlapping part is welded.

溶接接合は任意でよいが、図に示すように、支持力増強用形鋼２のウエブ９に、その上端縁１１から所定の深さ（Ｌ２）のスリット３を設け、そのスリット３を壁体構成用本体部材１のウエブ７の下端部１２に嵌挿させて嵌挿部４を構成し、この嵌挿部４におい溶接１３にて両部材を接合することで、前記壁体構成用本体部材１の下部に支持力増強用形鋼２を接合してなる壁体構成部材１００を構成する。   As shown in the drawing, a slit 3 having a predetermined depth (L2) from the upper end edge 11 is provided on the web 9 of the support-strengthening structural steel 2 as shown in the figure. The wall body constituting main body member is formed by fitting the lower end portion 12 of the web 7 of the constituting main body member 1 to form the fitting inserting portion 4 and joining both members by welding 13 in the fitting inserting portion 4. The wall constituting member 100 is formed by joining the support-steel-enhancing shape steel 2 to the lower part of 1.

壁体構成用本体部材１と支持力増強用形鋼２を接合する手段は、溶接１３に代えてボルト接合としてもよい。この場合は、図２に実施形態１の変形例として示すように、壁体構成用本体部材１と支持力増強用形鋼２の嵌挿部４の部位において、支持力増強用形鋼２のウエブ９にスリット３とほぼ同じ長さで、所定の幅の接合フランジ１４を溶接しておき、この接合フランジ１４と、これに対向する壁体構成用本体部材１ウエブ７のと接合面に開設のボルト孔にボルト１５を挿入してナットを締結することで、壁体構成用本体部材１と支持力増強用形鋼２を強固に接合できる。   The means for joining the wall constituting main body member 1 and the support-strengthening shaped steel 2 may be bolted instead of the weld 13. In this case, as shown as a modification of the first embodiment in FIG. 2, the support-strengthening structural steel 2 is formed at the site of the wall-forming main body member 1 and the fitting-inserting portion 4 between the support-strengthening structural steel 2. A welding flange 14 having a predetermined width is welded to the web 9 in substantially the same length as the slit 3, and the bonding flange 14 and the wall-forming main body member 1 web 7 opposite to the welding flange 14 are opened on the joining surface. By inserting the bolt 15 into the bolt hole and fastening the nut, the wall member-forming main body member 1 and the support-strengthening shaped steel 2 can be firmly joined.

壁体構成部材１００の各部の長さの具体的１例を説明すると、壁体構成用本体部材１の長さ（Ｌ）が例えば１０ｍ、支持力増強用形鋼２の長さ（Ｌ１）が３．１ｍ、重なり部つまり、溶接長の長さ（Ｌ２）が１０ｃｍであり、よって、壁体構成部材１００の全長（Ｌ３）が１３．０ｍに構成するものである。勿論、各部の長さは、適宜変更して構わない。   Explaining a specific example of the length of each part of the wall member 100, the length (L) of the wall member main body member 1 is, for example, 10 m, and the length (L1) of the support-strengthening structural steel 2 is The overlap portion, that is, the length (L2) of the welded length is 10 cm, and thus the total length (L3) of the wall member constituting member 100 is 13.0 m. Of course, you may change the length of each part suitably.

実施形態１に係る壁体構成部材１００を複数本用いて打設などの手段で基礎地盤に貫入させて土留め壁など各種の壁体を構築できる。この場合、互いに結合する全ての壁体構成部材を実施形態1に係る支持力増強用形鋼２で補強された壁体構成部材１００で構築してもよいし、または、この壁体構成部材間１００と通常の溝形鋼矢板とを組み合わせて構築してもよい。   Various wall bodies such as a retaining wall can be constructed by using a plurality of wall body constituting members 100 according to Embodiment 1 and penetrating the foundation ground by means such as placing. In this case, all the wall members that are coupled to each other may be constructed with the wall members 100 reinforced with the support-strengthening structural steel 2 according to the first embodiment, or between the wall members.

Considering the efficiency of the quantity, as in the first embodiment, a part of the overlap (L4) is provided, and the web 7 and the flange 18 are welded to each other at the overlap (L4).

また実施形態２において、溶接１３により前記壁体構成用本体部材１と支持力増強用形鋼２を接合する手段に代えてボルト接合としてもよい。この場合は、前記壁体構成用本体部材１と支持力増強用形鋼２の重なり部（Ｌ４）において、ウエブ７とフランジ１８を挿通するようにボルトを配設し、ナットを締結するとよい。   Moreover, in Embodiment 2, it is good also as a bolt joining instead of the means which joins the said main body member 1 for wall structure and the structural steel 2 for a supporting force reinforcement by the welding 13. FIG. In this case, bolts may be disposed so as to pass through the web 7 and the flange 18 in the overlapping portion (L4) between the wall constituting main body member 1 and the supporting force enhancing structural steel 2 and the nut may be fastened.

実施形態２に係る壁体構成部材１００を複数本用いて打設などの手段で基礎地盤に貫入させて壁体を構築できる。この場合、互いに結合する全ての壁体構成部材を実施形態２に係る壁体構成部材１００ａで構築し、または、壁体構成部材間１００ａと通常の溝形鋼矢板とを組み合わせて構築してもよいのは実施形態１と同じである。   A wall body can be constructed by using a plurality of wall body constituent members 100 according to Embodiment 2 and penetrating the foundation ground by means such as placing.
