Embodiment Construction

[0028] In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific embodiments are described in detail with reference to the accompanying drawings.

[0029] The steel pipe reactive powder concrete column-flat beam-shear wall structural system of the present invention comprises a steel pipe concrete column, a reinforced concrete beam and a reinforced concrete shear wall 5, and is characterized in that: the steel pipe concrete column is cast by using active powder concrete The steel tube reactive powder concrete column 1, the reinforced concrete beam is a flat beam 2, 3 or 4, that is, the width of the reinforced concrete beam is greater than or equal to the height of the beam.

[0030] In this example, the weight ratio of each component of active powder concrete per cubic meter is: cement: silica fume: sand: ground quartz powder: superplasticizer: steel fiber: water=1:0.23:1.1:0.39: 0.019:0.175:0.19. The sand...

Abstract

The invention relates to a steel pipe reactive powder concrete column-flat beam-shear wall structure system, which comprises steel pipe concrete columns, reinforcing steel bar concrete beams and reinforcing steel bar concrete shear walls, wherein each steel pipe concrete column is a steel pipe reactive powder concrete column formed by pouring reactive powder concrete, and each reinforcing steel bar concrete beam is a flat beam, namely the width of each reinforcing steel bar concrete beam is larger than or equal to the height of the same. Since the compression strength of the reactive powder concrete (RPC) is 4-10 times of that of common concrete, the RPC and steel pipes are combined to form the steel pipe RPC columns, the section size of each column is greatly reduced, and the usable area of a building is increased. Additionally, the structure system has the advantages of a flat beam structure, such as capability of lowering story height, avoiding pipelines to penetrate through the beams and the like, thereby having extremely good comprehensive economic benefits and being suitable for large-scale popularization and application.

Description

technical field [0001] The invention relates to a building structure system in the construction field, and more specifically refers to a steel tube reactive powder concrete column-flat beam-shear wall structure system. Background technique [0002] With the development of high-rise buildings in our country, more and more places have built or are planning to build high-rise and super high-rise buildings. Steel tube concrete columns have become the choice of many high-rise and super high-rise buildings. The use of steel tube concrete columns can improve the ultimate bearing capacity of the columns and Plastic deformation ability, reduce the cross-sectional area of ​​the column, and increase the building space. However, for super high-rise buildings, the concrete-filled steel tube column is still large in cross-sectional size, and its bearing capacity still cannot meet the design requirements. If steel bars (longitudinal bars, stirrups, and profile steel) are installed in the s...
