Application of ribbed floors and wide flat beams in frame-core tube structure system

Abstract

The invention discloses application of ribbed floors and wide flat beams in a frame-core tube structure system. According to the application of the ribbed floors and the wide flat beams in the frame-core tube structure system, the wide flat beams with the small section height are used for replacing traditional frame beams with the large section height, the floors outside a core tube are all the ribbed floors, connection of peripheral frame columns and the core tube is achieved, the clear height of a corridor is increased, the clear height of the corridor can be increased by at least 300 mm, and comfort is improved; meanwhile, the ribbed floors are used for replacing the traditional floors, formwork erecting can be reduced in the construction process, the construction difficulty is lowered, the construction efficiency is improved, and the construction period can be effectively shortened; and meanwhile, the ribbed floors are adopted to replace the traditional floors, the wide flat beams are adopted to replace the traditional frame beams, the frame-core tube is improved, the main body structures of frame columns and the core tube are not changed, and the shock strength of a building can be effectively improved.

Description

technical field [0001] The present invention relates to the field of construction, in particular to the application of densely ribbed floors and wide flat beams in frame-core tube structures, especially the combination of densely ribbed floors and wide flat beams as connecting structures in high-rise buildings with frame-core tube structures as structural systems applications in buildings. Background technique [0002] The frame-core tube structure refers to the structural system composed of the frame system composed of peripheral beams and columns and the central tube. Because of its good mechanical performance and relatively flexible internal space, it has become the current international high-rise building. It is the mainstream structural form and is widely used in super high-rise buildings. [0003] Such as figure 1 As shown, in the frame-core tube structure, there is often a large distance between the peripheral frame column 1 and the core tube 2, and the frame beam 3...

Problems solved by technology

For example, when the height of the structural layer is 3.3m, the section height of the frame beam 3 is 700mm (ie 0.7m), plus the space occupied by the water, electricity, heating and other pipelines in the building, as well as the brick laying and Suspended ceilings cause the clear height of each floor of the building to be less than 2.3m, seriously affecting the comfort of the corridor

However, there are many problems in the construction of the slab-column-shear wall structure: firstly, the thicker slab without beams increases the amount of concrete and reinforcement, and increases the total project cost; secondly, in order to obtain more accurate The calculation and analysis of the structure, the slab-column usually adopts the finite element calculation method, which increases the calculation time, and the safety reserve of the obtained result is small, and there are safety problems
