本発明は、地下又は半地下の店舗地下駐車場、倉庫等を
構築するための地下構造物の構築方法に関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method of constructing an underground structure for constructing an underground or semi-underground store, underground parking lot, warehouse, etc.
従来、地下構造物を構築する場合、予め構築予定部分を
掘削しておき、最下層より上層に向かって順次スラブ、
柱を構築してゆく方法や、掘削しながら上層から下層に
向かって順次柱等を樹立してゆく方法（いわゆる逆打工
法）があるが、いずれも、仮設時に切張、腹起し等を構
築して施工を進めなければならず、多大の仮設費と仮設
時間を必要とするという不都合があった。Conventionally, when constructing an underground structure, the area to be constructed is excavated in advance, and slabs are sequentially constructed from the lowest layer to the upper layer.
There are two methods: one is to build columns, and the other is to build columns sequentially from the upper layer to the lower layer while excavating (the so-called reverse construction method), but both methods require cutting, raising, etc. during temporary construction. There was an inconvenience in that it had to be constructed and the construction proceeded, which required a large amount of temporary construction cost and time.
そこで、かかる不都合を解消するために、敷地の周囲に
杭兼用の柱を打設し、かつ、地下外壁として地下連続壁
を構築した後、地表面で予め構築した必要階数骨のスラ
ブを前記柱に沿って吊り下ろしながら該スラブ下の地盤

に仮固定すると共に、仮固定したスラブより上部の柱に
コンクリートを打設し、かつ、該スラブ周辺部と前記地
中連続壁を接合する地下構造物の構築方法が開発されて
いる（特開昭６２−７２８２２号公報参照）。Therefore, in order to eliminate this inconvenience, after driving pillars that also serve as piles around the site and constructing an underground continuous wall as an underground outer wall, a slab of the required number of floors constructed in advance on the ground surface is attached to the pillars. The ground below the slab is excavated while being lowered along the slope, and the slabs on the upper floor are temporarily fixed in place in order from the slab on the upper floor, and concrete is poured into the pillars above the temporarily fixed slab. A method for constructing an underground structure that connects the surrounding area of the slab and the underground continuous wall has been developed (see Japanese Patent Laid-Open No. 72822/1982).
しかしながら、この従来方法では、地下連続壁を鉄筋コ

地の有効利用の点で不利であると共に、地下連続壁の形
状精度が悪い。施工にかなり時間がかかる。地下連続壁
にスラブとの接合部材を取り付は難い等の欠点があった
。However, in this conventional method, since the underground continuous wall is made of reinforced concrete, its cross section becomes thick, which is disadvantageous in terms of effective use of the site, and the shape accuracy of the underground continuous wall is poor. Construction will take a considerable amount of time. There were drawbacks such as difficulty in attaching the joining member to the slab to the underground continuous wall.
また、地下連続壁は前述の如（コンクリート製で地下水
が浸透し易いから、外部止水も内部止水も行わない場合
には、各階床面積が狭くなっても、地下連続壁の内側に
さらに連続壁を設け、該連続壁と地下連続壁との間を通
して該地下連続壁から浸入した地下水を地下ピットに集
める必要があるため、地下連続壁がコンクリート製であ
るということは各階床面積を確保する上で重大な欠点と
なっており、この点でも敷地の有効利用ができなかった
。In addition, as mentioned above, underground continuous walls are made of concrete and are easily penetrated by groundwater, so if neither external nor internal water shutoff is done, even if the floor area of each floor becomes narrower, there will be more water inside the underground continuous walls. Since it is necessary to install a continuous wall and collect groundwater that has entered from the continuous wall into an underground pit through the space between the continuous wall and the continuous underground wall, the fact that the continuous underground wall is made of concrete means that the area of each floor can be secured. This was a serious drawback in terms of the construction, and in this respect, the site could not be used effectively.

材を取り付は易くできるようにすることを目的とする。The present invention has been made to solve the above-mentioned problems, and it is possible to ensure reliability and water-stopping properties as an underground external wall while reducing the cross section of the underground external wall through rapid construction, and to improve the shape accuracy of the underground external wall. It is an object of the present invention to provide a method that allows easy attachment of a joining member to a slab.

A plurality of steel continuous wall members each having a connecting piece extending on the opposite side of the pipe and having an engaging part at the tip thereof and continuously protruding in the longitudinal direction of the pipe are connected to each other at the engaging parts to form the continuous wall member. The slab is press-fitted into the wall, and then the ground inside the underground outer wall thus formed is excavated and suspended, and the slab is joined to the underground outer wall via a joining material protruding from a continuous wall within the underground outer wall. It is characterized by
