Abstract

The invention provides a novel composite floor system for a super high-rise building and aims to overcome the defects that an existing high-rise building is small in span, large in self-weight, large in occupied space and the like. The novel composite floor system is characterized in that an interlayer composite floor system assembly is arranged on the top of each layer of the ground portion of the super high-rise building; each interlayer composite floor system assembly is composed of a core tube wall cap and a beam, wherein the core tube wall cap is a closed annular frame body; each beam is composed of a beam body and a wide and flat beam skeleton assembly. The novel composite floor system for the super high-rise building has the technological effects that the height of the beams in the novel composite floor system is only 8% to 15% of that of beams in a traditional technological structure, and therefore building space losses are saved; the usage amount of reinforcing bars and concrete in the beams is reduced due to the fact that hollow steel tubes are arranged internally, the self-weight of the structure is reduced, and structural stiffness is enhanced; in addition, due to the fact that the core tube wall caps and the beams are integrated, namely, the span of the beams is increased, therefore, labor and materials are saved, usable areas are increased, and firmness and durability of the building are improved.

Description

technical field [0001] The invention belongs to the technical field of buildings, and in particular relates to a novel composite floor system for super high-rise buildings in high-rise building construction. Background technique [0002] Frame-core tube structure is a structural type commonly used in high-rise buildings. It is a structural system composed of a core tube located in the middle of the building and a peripheral frame. The core tube is surrounded by an outer wall (shear wall) arranged in the center of the floor. , It has a great ability to resist lateral force. The frame is arranged around the building. Generally, the column spacing is relatively large, which can provide a large space for the building. This structural form is also produced to meet the needs of the building. With the continuous improvement of the level of architectural design, high-rise buildings have higher requirements for floor clearance. While ensuring structural stability, how to effectively ...
