Embodiment Construction

[0025] The in-line steel-high performance concrete composite member of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0026] A schematic cross-sectional view of an embodiment of the in-line steel-high performance concrete composite member proposed by the present invention, such as figure 1 , the composite member includes a box-shaped steel piece 1, a connecting piece 2 and a concrete 3, the connecting piece 2 is connected to the long-side steel plate of the box-shaped steel piece 1, and the opposite side connecting pieces 2 are lapped together; The area is poured with concrete 3. The connecting piece is made of steel bars; or the connecting piece is made of deformed steel bars; the connecting piece is U-shaped. In the actual project, longitudinal bars are arranged in the unpoured concrete space in the in-line steel-high performance concrete composite member, which is connected with the longitudinal bars o...

Abstract

The invention relates to an I-shaped steel and high-performance concrete combined member, and belongs to the technical field of combined structures.The I-shaped steel and high-performance concrete combined member comprises a box-shaped steel member, connectors and high-performance concrete.The connectors are connected onto steel plates at the long edges of the box-shaped steel member, and the connectors on opposite sides of the I-shaped steel and high-performance concrete member are overlapped with one another; the high-performance concrete is arranged in regions where the connectors are located.The I-shaped steel and high-performance concrete combined member has the advantages that the stress performance of structures can be improved, and the industrialization level of the structures can be upgraded.

Description

technical field [0001] The invention relates to an in-line steel-high-performance concrete composite member. Background technique [0002] The steel structure has a high degree of industrialization and good mechanical performance, and is more and more widely used in building structures. Shear walls have high bearing capacity and high lateral stiffness, and are the main lateral force-resistant structural components of high-rise structures. [0003] The cross-section of composite members such as CFST columns is generally square or circular, giving full play to the restraint effect of steel pipes. The steel-concrete composite shear wall has the performance advantages of the shear wall, and also has the advantages of the production and installation of the steel structure; the ratio of the long side to the short side of the steel-concrete composite shear wall is greater than 1, and the restraint effect of the steel is reduced. Generally, the components are separated by setting ...
