本発明は建築物等の基礎工事に適用される基礎、地中梁
等の基礎構築物の施工方法に係るものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method of constructing foundation structures such as foundations and underground beams applied to foundation construction of buildings and the like.
（従来の技術）
従来、建築物等の基礎工事においては、基礎や地中梁を
構築する場合、型枠の組立、解体が行なわれるように、
同基礎、地中梁の大きさよりも広い面積に亘って掘削し
、掘削土を場内または場外に搬出する。(Conventional technology) Conventionally, in foundation work for buildings, etc., when constructing foundations and underground beams, formwork is assembled and dismantled.
An area larger than the size of the foundation and underground beams will be excavated, and the excavated soil will be carried inside or outside the site.
かくして所定の深さまで掘削したのち割栗地業を施し、
捨てコンクリートを打設し、基礎や地中梁の位置を墨出
して、同位置に鉄筋を組立てる。After excavating to a predetermined depth in this way, we applied the Waricuri method.
Pour concrete, mark out the locations of the foundation and underground beams, and assemble reinforcing bars at the same locations.
次いで基礎、地中梁の型枠を組立てスラブコンクリート
下端までコンクリートを打設し、同打設コンクリートの
硬化後、前記型枠を解体したのち、基礎、地中梁の余堀
り部に土砂等を埋戻し、地盤の転圧後砂利地業を施す。Next, formwork for the foundation and underground beams is assembled and concrete is poured to the bottom edge of the slab concrete. After the poured concrete has hardened, the formwork is dismantled, and earth and sand etc. are poured into the excess excavations of the foundation and underground beams. After backfilling and compacting the ground, apply gravel.
次いで防濡、断熱処理後、スラブ補強筋を配筋してスラ
ブコンクリートを打設する。Next, after moisture-proofing and heat insulation treatment, slab reinforcement is placed and slab concrete is poured.
かくして基礎工事を完了し、次の工程に移る。In this way, the foundation work is completed and we move on to the next process.
（発明が解決しようとするｔＪｌｌり
しかしながら前記従来の方法には、次のような問題点が
ある。However, the conventional method has the following problems.
＋ｉｌ 型枠が組立て解体されるように、基礎、地中

多くなり、掘削土砂を場内、または場外へ搬出し、埋戻
し時には場外より土砂を搬入するため、作業量が増大し
、工費が嵩む。+il In order to assemble and dismantle the formwork, the excavation is carried out wider than the prescribed size of the foundation and underground beams, so the amount of excavated soil is large, and the excavated soil is carried inside or outside the site, and when backfilling, it is carried out from outside the site. Carrying in earth and sand increases the amount of work and construction costs.
Ｔｉ１ｌ 基礎、地中梁の型枠を組み、スラブコンク
リート下端までコンクリートを打設し、同打設コンクリ
ートの硬化後でなければ型枠を解体することができず、
作業手順が悪く作業性に難点がある。Ti1l Formwork for the foundation and underground beams was constructed, concrete was poured to the bottom of the slab concrete, and the formwork could not be dismantled until the poured concrete had hardened.
The work procedure is poor and there are difficulties in workability.
（ｉｉｉｌ 型枠の組立、解体により労務が増大し、
多くの資材が必要となる。(iii) Labor increases due to assembly and dismantling of formwork,
Many materials are required.
本発明は前記従来技術の有する問題点に鑑みて提案され
