Construction method of high-altitude ring beam cantilever structure
The invention discloses a construction method of a high-altitude ring beam cantilever structure. The construction method comprises the following steps of performing slip form construction to 36.75 m,and embedding embedded parts and anchoring steel bars; sliding a platform, reinforcing climbing poles, and removing slip forms; mounting a main beam and inclined struts below a slip form platform through a hanging basket; dismounting slip form platform supporting tie bars at the corresponding positions, laying secondary beams, welding the secondary beams to the main beam, and then laying battens and forms; erecting ring beam scaffold vertical rods on the main beam, erecting scaffolds, and hanging a large-hole safety net at the same time; and binding ring beam reinforcing steel bars, mounting the forms, carrying out reservoir top part embedding and bolt mounting, and pouring concrete. According to the construction method, the main beam is laid at a certain interval at the bottom of a ring beam according to the upper structure load, the secondary beams are laid on main beam channel steel, the channel steel inclined struts are additionally arranged at the lower portion, a steel structuretriangular frame is formed and bears all the loads of the upper cantilever ring beam, and round steel is adopted for manufacturing a hoop to be fixed to the inclined struts, so that the stability of the inclined struts is consolidated.
本发明公开一种高空环梁悬挑结构的施工方法，按照如下工序依次施工：滑模施工至36.75m，埋设预埋件及锚固钢筋；滑空平台，加固爬杆，拆除滑模模板；在滑模平台下使用吊篮安装主梁及斜撑；拆除对应位置滑模平台支撑系杆，铺放次梁，并将次梁焊接到主梁上，然后铺放木方及模板；在主梁上搭设环梁脚手架立杆，搭设脚手架，同时挂上大眼安全网；环梁钢筋绑扎，模板安装，库顶埋件及螺栓安装，浇灌混凝土。本发明在环梁底部根据上部结构荷载按一定间距铺设主梁，在主梁槽钢上铺设次梁，下部增加槽钢斜撑，形成钢结构三角架，承担上部悬挑环梁所有的荷载，采用圆钢制作一道卡箍固定在斜撑上，巩固斜撑的稳定性。
