Description
【発明の詳細な説明】 「産業上の利用分野」 本発明は、地下連続壁と鉄骨鉄筋コンクリート又は鉄筋
コンクリート建物の躯体との接合構造に関する。TECHNICAL FIELD The present invention relates to a joint structure between an underground continuous wall and a steel frame reinforced concrete or a skeleton of a reinforced concrete building.
「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 Techniques and Inventions” In recent years, in the construction of a basement floor of a building or the construction of an underground building, it has been practiced to use an underground continuous wall for a mountain stop as a structure of an underground outer wall. ing.

クリートである。In this case, as shown in FIG. 3, a shear provided with an underground continuous wall 1 and a post-fabricated beam 2 (and a pillar) of a building, which is provided with a long anchor portion 31 of a hook shape, a U shape, a loop shape, or the like. The connectors 3 are connected by being buried, and the underground continuous wall 1 is also used as the underground outer wall of the building. In the figure, 11 and 21 are rebar cages, and 12 and 22 are 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, when the seismic force and earth pressure acting on the underground outer wall is large, or when the building is special and requires a thick underground outer wall, not only the beams and columns are post-cast, but also a part of the external wall is post-cast. There is a need to.

ト高を招く。However, in such a case, a rear connector external wall also needs a shear connector, and the number of shear connectors becomes enormous, which causes a problem in labor and construction period. In addition, the shear connector used for the post-strike outer wall becomes a special one, which causes a considerable cost increase.
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 is intended to solve such conventional problems.

る。"Operation" Because of the above configuration, the uneven steel plate with steel rods with steel rods attached on both sides and embedded intervene acts as a strong connector that connects the underground continuous wall and the outer wall to be stamped. The steel rods increase the adhesion of concrete to both sides of the uneven steel plate. As a result, the corrugated steel sheet with a steel bar acts as a part of the structure having a large shearing force.
Moreover, the uneven steel plate acts as a highly reliable water stop plate.

A deck plate 5, which is an uneven steel plate, is embedded between the continuous underground wall 1 and the outer wall 4 after finishing, with the groove direction facing up and down. The deck plate 5 has both sides for increasing the adhesive force of concrete. , A plurality of steel rods 6 are arranged side by side in the groove direction. The steel rods 6 may be reinforcing bars.

る。[Advantage of the Invention] According to the present invention, since the corrugated steel plate with steel rods with steel rods on both sides is embedded between the underground continuous wall and the post-cast outer wall, the corrugated steel plate with steel rods underground The continuous wall and the outer wall for post-casting can be strongly bonded, and the attached steel rods on both sides can increase the adhesion of concrete to both sides of the corrugated steel sheet. And, in the uneven steel plate with steel rod,
It can be made to work as a part of a structure having a large shearing force, a structure having excellent mechanical properties can be easily constructed, and workability can be improved. Therefore, it is possible to omit the shearing connector and the work of mounting the shearing connector, shorten the construction period, and reduce the cost. Further, the wall thickness of the outer wall for post-strike can be reduced.
