Embodiment Construction

[0034] The L-shaped steel-concrete composite structural member of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0035] An embodiment of the L-shaped steel-concrete composite structural member proposed by the present invention, such as figure 1 , the structural member includes an L-shaped steel member 1 with an outer profile formed by connecting steel plates or section steel. There is a partition 2 inside the steel member 1, and the steel member is divided into 3 cavities 3. There is no concrete in the cavity at the corner, and the remaining 2 Each cavity contains concrete 4 (ie precast concrete). In another embodiment, such as figure 2 , The L-shaped steel member 1 is divided into three cavities 3 by the partition plate 2, and there is concrete 4 (that is, precast concrete) in the cavity at the corner, and there is no concrete in the remaining cavities. The number of cavities divided by the partition p...

Abstract

The invention relates to an L-section steel and concrete combined structural member and belongs to the technical field of steel and concrete structures. This structural member comprises a steel member with L-shaped contour and concrete, the steel member is formed by connecting steel plates or section steel and forms a plurality of cavities, concrete is poured into part of the cavities, and other cavities receive no concrete. Load-carrying capacity and industrial level of a structure will be improved.

Description

technical field [0001] The invention relates to an L-shaped steel-concrete composite structural member. Background technique [0002] Steel-concrete composite structural members have the advantages of concrete structure and steel structure, and are more and more widely used in building structures. The shear wall has high bearing capacity and high lateral stiffness, and is the main lateral force-resistant structural component of high-rise structures. [0003] Composite members such as concrete-filled steel tube columns are generally square or circular in cross-section, giving full play to the confinement effect of steel tubes. The steel-concrete composite shear wall has the performance advantages of the shear wall, and also has the advantages of the manufacture and installation of the steel structure; the ratio of the long side to the short side of the section of the steel-concrete composite shear wall is greater than 1, and the restraining effect of the steel is reduced. G...
