「従来の技術と発明が解決しようとする問題点」近年、
建物の地下階の構築又は地中建物の構築において、山止
め用の地下連続壁を地下外壁の構造体として利用するこ
とが行われている。“Problems to be solved by conventional technology and inventions” In recent years,
BACKGROUND OF THE INVENTION In constructing underground floors of buildings or underground buildings, underground continuous walls for heaping are used as structures for underground outer walls.
この場合、第５図に示すように、地下連続壁ｌと建物の
後打ちの！１２ （及び柱）とを、かぎ型、Ｕ字型、ル
ープ型等の長いアンカ一部分３１・・・を備えたシアコ
ネクタ３の埋設により結合し、地下連続壁１を建物の地
下外壁に兼用する０図中、１１．２１は、鉄筋かご、１
２．２２は、後打コンクリートである。In this case, as shown in Figure 5, the continuous underground wall l and the after-casting of the building! 12 (and columns) by burying a shear connector 3 equipped with a long anchor part 31 of a hook shape, U shape, loop shape, etc., and the underground continuous wall 1 is also used as the basement outer wall of the building. 0 In the figure, 11.21 is a reinforcing bar cage, 1
2.22 is post-cast concrete.
ところで、地下外壁に作用する地震力、土圧が大きい場
合又は建物が特殊なもので厚い地下外壁を要する場合に
は、梁、柱を後打ちするだけでなく、外壁の一部をも後
打ちする必要がある。By the way, if the seismic force or earth pressure acting on the underground external wall is large, or if the building is special and requires a thick underground external wall, it is necessary to post-cast not only the beams and columns, but also part of the external wall. There is a need to.
しかし、斯様な場合には１．後打ち外壁にもシアコネク
タを要して、シアコネクタの数が膨大な量となり、作業
手間、工期において問題が生ずる。However, in such a case, 1. Shear connectors are also required for the post-cast exterior walls, resulting in a huge number of shear connectors, which causes problems in terms of work time and construction period.
また、後打ち外壁に用いるシアコネクタは、特殊なもの
となり、かなりのコスト高を招く。In addition, the shear connector used for the post-fabricated exterior wall is a special one, resulting in a considerable increase in cost.
本発明は、斯る従来の問題点を解決しようとするもので
ある。The present invention attempts to solve these conventional problems.
「問題点を解決するための手段」
本発明は、地下連続壁と後打ち外壁との間に、凹凸面を
形成したデツキプレート、キーストンプレート、縞鋼板
等の凹凸！ｉ１ｍを埋入介在させて両者を結合して成る
。"Means for Solving the Problems" The present invention provides an uneven structure such as a deck plate, a keystone plate, a striped steel plate, etc., which have an uneven surface between an underground continuous wall and a post-cast exterior wall. The two are bonded by implanting i1m.
「作用」
如上の構成であるから、介在させた凹凸鋼板は、地下連
続壁と後打ち外壁とを継ぐコネクタとして作用し、せん
断耐力の大きな構造体の一部として作用し、また、信頼
性の高い止水板として作用する。``Function'' With the above structure, the interposed uneven steel plate acts as a connector connecting the underground continuous wall and the post-cast exterior wall, and acts as a part of the structure with high shear strength, and also improves reliability. Acts as a high water stop.
「実施例」 そのｌ。"Example" That l.
第１図、第２図は、第１の例を示し、地下連続壁１と後
打ち外壁４との間に、凹凸鋼板たるデツキプレート５を
、溝方向を上下に向けて埋入介在させ、該デプレート５
には、コンクリートの付着力を高めるために両面に複数
の鋼棒６・・・を溝方向に直交させて並設している。な
お、鋼棒６・・・は、鉄筋でもよい。FIGS. 1 and 2 show a first example, in which a deck plate 5, which is a textured steel plate, is inserted between the underground continuous wall 1 and the post-cast exterior wall 4, with the groove direction facing up and down, The deplate 5
In order to increase the adhesion of concrete, a plurality of steel rods 6 are arranged in parallel on both sides perpendicular to the groove direction. Note that the steel rods 6 may be reinforcing bars.
施工手順は次の通りである。The construction procedure is as follows.
■、まず、掘削機により、地下連続壁用の掘削溝を掘削

キプレート５とはあらかじめ一体化させてユ二フトとし
ておいてもよい。(1) First, an excavation machine is used to excavate an excavation groove for the underground continuous wall, and the deck plate 5, to which steel rods 6 are welded in advance, is inserted into the excavation groove and brought into contact with the side ditch wall. Further, the reinforcing bar cage 11 and the deck plate 5, in which the required reinforcing bar cage 11 is erected, may be integrated in advance to form a unit.
続いて、掘削溝内にトレミー管を用いてコンクリート１
２を打設し、硬化させて、地下連続壁ｌを構築する。Next, concrete 1 is poured into the excavated trench using a tremie pipe.
2 is poured and hardened to construct the underground continuous wall l.
■０次に、その地下連続壁ｌの内側に建物用空間を掘削
