Embodiment Construction

[0022] The specific connection mode of the column joint connection device of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] as attached Figure 1~5 As shown, a column joint connecting device of an assembled steel structure system of the present invention includes a lower column (1), an upper column (2), a lower column hook (3), and an upper column bent plate (4).

[0024] The lower column (1) and the lower column hook (3) are welded together at the factory to form a component A1; the upper column (2) and the upper column bent plate (4) are welded together at the factory to form a component A2.

[0025] After the components A1 and A2 are hoisted on site, concrete is poured inside the column for connection.

[0026] The above is a typical embodiment of the present invention, and the practice of the present invention is not limited thereto.

Abstract

The invention discloses a column joint connecting device of an assembled steel structure system and belongs to the technical field of structural engineering. The column joint connecting device comprises a lower column, an upper column, a lower column lifting hook and an upper column bent plate, the lower column and the lower column lifting hook are welded into a whole in a factory, and the upper column and the upper column bent plate are welded into a whole in the factory. Welding is completed in the factory, lifting is adopted for on-site assembly, and concrete is fully poured into the insides of the columns. A column joint is around a point of inflection, so that the point of inflection is slightly stressed; the concrete has certain connecting effect with reinforced concrete formed by the bent plate and the lifting hook inside the columns, and both size and length of the lifting hook and the bent plate can be adjusted to adjust connecting force, so that welding between the upper column and the lower column is not a must and depends on stress of the columns. The column joint connecting device can greatly improve construction speed and quality and can adapt to development of assembled steel structures.

Description

technical field [0001] The invention relates to a column joint connecting device of an assembled steel structure system, belonging to the technical field of structural engineering. Background technique [0002] The prefabricated steel structure system refers to the building produced by manufacturing housing units or components according to uniform and standard building part specifications, and then transporting them to the construction site for assembly in place. It is characterized by light building weight, energy saving and environmental protection, fast construction speed, and high degree of industrialization. It can solve many problems such as the low level of construction industrialization in my country, low labor productivity in house construction, and low quality of traditional house products, and adapt to the development of my country's construction industry. [0003] The connection method of column joints is an important connection method in the fabricated steel str...
