REINFORCEMENT STRUCTURE FOR UNDERGROUND CONTINUOUS WALL
To provide a reinforcement structure for an underground continuous wall that can streamline the arrangement work of an element, suppress cracks that occur in a RC wall plate portion that is continuous with a joint portion, and improve the shear strength of the joint portion.SOLUTION: A preceding element 2 (first element) has a first unevenness forming portion 28 and a first wall plate portion 29 located on a side away from a second element from the first unevenness forming portion 28. A trailing element 3 (second element) has a second unevenness forming portion 38 and a second wall plate portion 39 located on a side away from the preceding element 2 from the second unevenness forming portion 38. The first wall plate portion 29 is provided with a first bundled reinforcing bar 221 in which a plurality of reinforcing bars extending in the wall height direction are bundled on the side of the first unevenness forming portion 28. The second wall plate portion 39 is provided with a second bundled reinforcing bar 321 in which a plurality of reinforcing bars extending in the wall height direction are bundled on the side of the second unevenness forming portion 38.SELECTED DRAWING: Figure 2
【課題】エレメントの配筋作業を効率化でき、継手部と連続するＲＣ造の壁板部に生じるひび割れを抑止し、継手部のせん断耐力を向上させることができる地中連続壁の補強構造を提供する。【解決手段】先行エレメント２（第１エレメント）は、第１凹凸形成部２８と、第１凹凸形成部２８よりも第２エレメントと離れる側に位置する第１壁板部２９と、を有し、後行エレメント３（第２エレメント）は、第２凹凸形成部３８と、第２凹凸形成部３８よりも先行エレメント２と離れる側に位置する第２壁板部３９と、を有し、第１壁板部２９には、第１凹凸形成部２８側に壁高さ方向に延びる複数の鉄筋が束ねられた第１束ね鉄筋２２１が設けられ、第２壁板部３９には、第２凹凸形成部３８側に壁高さ方向に延びる複数の鉄筋が束ねられた第２束ね鉄筋３２１が設けられている。【選択図】図２
