A steel structure roof structure of a tower building and its construction method

Abstract

A steel structure roof structure of a tower building and its construction method, including a roof main body, corner hanging columns and side hanging columns; the roof main body is in the shape of an inverted pyramid, including a tower crown structure, a peripheral structure and a connecting grid; the tower The crown structure is set on the top of the core tube; the peripheral structure includes slanted columns and frame beams; the frame beams are rectangular and connected to the top of the slanted columns; the connecting grid is connected between the tower crown structure and the peripheral structure; The top plate of the frame tube corresponds to the four corner positions of the frame beam; the bottom of the corner hanging column is connected to the top plate through the corner post connecting seat; the side hanging column is set on the top plate of the outer frame tube, corresponding to the position where the upper side of the frame beam is connected to the short column place; the bottom of the side hanging column is connected with the top plate through the side column connecting seat. The invention solves the technical problems that the traditional steel structure roof is simple in shape, difficult to stand out from the building group, and the traditional construction method cannot satisfy the construction of the steel structure roof structure with complex structure, and cannot guarantee the safety of the installation process.

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
