Construction method of tower crown structure of super high-rise building
The invention discloses a construction method of a tower crown structure of a super high-rise building, which comprises the following steps: according to the tower crown structure, a hoisting unit is pre-assembled on the ground, and the hoisting unit comprises a double-truss hoisting unit, a single-truss hoisting unit and a triangular hoisting unit; one tower crane is used for installing a double-truss hoisting unit in the middle of the south side of the super high-rise building; before hoisting, a profile steel support is welded to the lower portion of the double-truss hoisting unit, and a cable rope is bound to the lower portion of the double-truss hoisting unit; after hoisting in place, connecting the double-truss hoisting unit by using a pin shaft; the hoisted double-truss hoisting unit is kept connected with a tower crane, and the other tower crane is used for hoisting a connecting rod piece between the double-truss hoisting unit and a core tube of the super high-rise building. According to the construction method of the tower crown structure of the super high-rise building, the steps are reasonable, the hoisting units are assembled on the ground in advance, and the high-altitude welding amount is effectively reduced; and double lifting is matched with in-situ lifting, so that the construction safety is ensured, the construction period is shortened, and the construction cost is reduced.
本发明公开了一种超高层建筑的塔冠结构的施工方法，其包括：根据塔冠结构，在地面预先组装吊装单元，所述吊装单元包括双榀吊装单元、单榀吊装单元和三角吊装单元；使用其中一台塔吊安装超高层建筑南侧中间部位的双榀吊装单元；起吊前，在所述双榀吊装单元的下部焊接型钢支撑并绑扎缆风绳；吊装到位后，使用销轴连接所述双榀吊装单元；吊装的所述双榀吊装单元与塔吊保持连接，使用另一台塔吊吊装所述双榀吊装单元与超高层建筑的核心筒之间的连接杆件。本发明提供的一种超高层建筑的塔冠结构的施工方法，其步骤合理，在地面预先组装吊装单元，有效降低高空焊接量；使用双抬吊配合原位吊装，保证施工安全性，缩短了施工周期，降低施工成本。
