Steel structure roof structure of tower building and construction method thereof

Abstract

The invention discloses a steel structure roof structure of a tower building and a construction method thereof. The steel structure roof structure comprises a roof body, corner hanging columns and side hanging columns. The roof body is in the shape of an inverted pyramid and comprises a tower crown structure, a peripheral structure and a connecting net frame. The tower crown structure is arrangedat the top of a core tube. The peripheral structure comprises oblique columns and a frame beam. The rectangular frame beam is connected to the tops of the oblique columns. The connecting net frame isconnected between the tower crown structure and the peripheral structure. The corner hanging columns are mounted on a top plate of a frame tube and positions corresponding to four corners of the framebeam. The bottoms of the corner hanging columns are connected with the top plate through corner column connecting seats correspondingly. The side hanging columns are arranged on the top plate of theframe tube and positions corresponding to connecting short columns of the upper side portion of the frame beam. The bottoms of the side hanging columns are connected with the top plate through side column connecting seats correspondingly. According to the steel structure roof structure of the tower building and the construction method, the technical problems that a traditional steel structure roofis simple in modeling and hard to stand out in building groups, a traditional construction method fails to meet construction requirements of steel structure roof structures with a complex structure,and the safety of the mounting process fails to be guaranteed are solved.

Description

technical field [0001] The invention belongs to the technical field of building engineering construction, and in particular relates to a steel structure roof structure of a tower building and a construction method thereof. Background technique [0002] With the rapid development of high-rise and super high-rise buildings, the height of new super high-rise buildings in major cities in China generally reaches more than 200 m. The top of high-rise buildings directly affects the design effect of the entire high-rise building, especially for super high-rise buildings above 200 m The top design of the building plays a finishing touch to the overall image of the building, and can make it stand out among the high-rise buildings. At present, most of the top structures of super high-rise buildings adopt the shape of steel structure roofs, and boldly adopt complex structural forms such as cantilever, suspension, and tilting. a series of unprecedented challenges. [0003] The construc...

Problems solved by technology

[0004] The purpose of the present invention is to provide a steel structure roof structure of a tower and its construction method, to solve the problem that the traditional steel structure roof is simple in shape, without innovation, without technically complicated structural forms such as overhanging, hanging, and tilting, which are difficult Standing out from the technical problems of the building complex, it is also necessary to solve the technical problems that the traditional construction methods cannot meet the construction of steel structure roof structures with complex structures, and cannot guarantee the safety of the installation process
