The invention relates to an external ring beam structure under a cantilever beam and a construction method thereof, and mainly aims to enhance the anti-collapse capability of the structure and the overall closing performance of an external wall ring beam. The external ring beam structure under the cantilever beam comprises a cantilever beam, a cantilever plate, an external ring beam and a cantilever beam lower ring beam part, wherein the external ring beam is integrally closed along the periphery of a building; the cantilever beam lower ring beam part and the external ring beam below the cantilever plate are not in the same plane, and the height H of the cantilever beam lower ring beam part is 180 mm away from the bottom surface of the cantilever beam; and the external ring beam and the cantilever beam lower ring beam part are integrally poured together by ring beam main reinforcements, beam lower connecting reinforcements, bottom connecting reinforcements and stirrups. Therefore, the external ring beam and the cantilever beam lower ring beam part on the high plane and the low plane form a closed whole along the periphery of the building, the structures are reliably connected in a pulling mode, and common stress is guaranteed.
本发明涉及一种悬挑梁下外加圈梁结构及其施工方法，主要是为了增强结构的抗倒塌能力和外墙圈梁的整体闭合性。包括悬挑梁、悬挑板、外加圈梁、悬挑梁下圈梁部分；所述的外加圈梁沿楼四周形成整体闭合；所述的悬挑梁下圈梁部分与悬挑板下的外加圈梁不在一个平面内，挑梁下圈梁部分的高度H距悬挑梁底面180mm；所述的外加圈梁和悬挑梁下圈梁部分由圈梁主筋、梁下连接筋、底部连接筋、箍筋整体浇筑在一起。这就使高、低两平面的外加圈梁和悬挑梁下圈梁部分沿楼四周形成闭合整体，结构互相可靠拉接，保证共同受力。
