Embodiment Construction
[0025] The specific connection mode of the L-2 type low-reinforcement outsourcing concrete shaped steel special-shaped column of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0026] as attached Figure 1~6 As shown, a L-2 type low-reinforcement outsourcing concrete shaped steel special-shaped column of the present invention includes shaped steel (1), outsourcing concrete (2), longitudinal erection reinforcement (3) and stirrups (4).
[0027] The outsourcing concrete (2) of the L-2 type low-reinforcement outsourcing concrete section steel special-shaped column is connected with the section steel (1) through vertical erection reinforcement (3) and stirrup (4), and longitudinal erection reinforcement (3) and stirrup (4) The reinforced cage and the section steel (1) are welded and connected. The welded part is the part where the stirrup and the section steel column are in contact. The welded connection is prefabricated in ...

The invention discloses an L-2 type low-reinforced concrete encased type specially-shaped steel column, and belongs to the technical field of structural engineering. A component adopts a concrete encased shape steel mode, wherein vertically erected steel bars and stirrups which are configured for the encased concrete do not participate in vertical stress; local stability of a specially-shaped column plate piece can be limited, the size of a shape steel can be reduced, and the problems of poor fire resistance, high possibility of rusting and the like of a steel structural building can be effectively solved; the size of the encased concrete is relatively small, so that the cross section of the component cannot be increased greatly, and inter-module assembly and repair can be performed according to requirements. The welding of a reinforcement cage and shape steel can effectively ensure effective adhesion of the encased concrete and the shape steel. The concrete encased type specially-shaped steel column is machined in a factory. An upper column is connected with a lower column only through shape steel welding connection or bolts; after the upper column and the lower column are connected, the encased concrete is added to a connecting part. The L-2 type low-reinforced concrete encased type specially-shaped steel column is high in industrialization degree; the integration of design, production and construction is realized; the level of housing industry is improved. The component is hoisted to be assembled on the scene, and the construction period is short.
Description
technical field [0001] The invention relates to an L-2 type low-reinforcement outsourcing concrete shaped steel special-shaped column, which belongs to the technical field of structural engineering. Background technique [0002] With the continuous advancement of national policies, the 16th National Congress of the Communist Party of China put forward the concept of new industrialization, and the 18th National Congress of the Communist Party of China proposed to take the road of new industrialization in Chinese style. The innovation and industrialization of the corresponding system of housing steel structure in my country ushered in unprecedented opportunities. [0003] The basic requirements of the Chinese-style new road to industrialization are to improve scientific and technological innovation capabilities, reduce environmental pollution, reduce energy consumption and improve economic efficiency. The characteristics of construction industrialization are mainly divided int...
