Multi-limb column used for fabricated steel structure house

Abstract

The invention relates to a construction component, in particular to a multi-limb column used for a fabricated steel structure house. The multi-limb column comprises multiple single-limb columns made of H-shaped steel. Every two adjacent single-limb columns are connected through horizontal connection beams made of H-shaped steel. Flange plates of the connection beams are fixedly connected with flange plates of the single-limb columns. Connection plates are arranged between flange plates of the adjacent single-limb columns. The upper ends and the lower ends of the connection plates are fixedly connected with the flange plates of the connection beams correspondingly. The two sides of each connection plate are fixedly connected with the flange plates of the corresponding single-limb column correspondingly. The upper portion and the top end of each connection plate are provided with a grouting hole and a grout vent hole correspondingly. The height of the connection beams corresponds to thefloor height of the steel structure house. The portions between the adjacent single-limb columns are filled with concrete to form a prefabricated piece. The height of the sections of the single-limb columns and the connection beams is smaller than or equal to the wall thickness of the steel structure house. By means of the multi-limb column, the supporting strength of the multi-limb column is ensured, the defect of wall bleed-out is overcome, the multi-limb column is prefabricated in a factory, advantages of fabricated houses are achieved, and the construction efficiency is improved.

Description

technical field [0001] The invention relates to a building component, in particular to a multi-leg column for a prefabricated steel structure residence. Background technique [0002] In recent years, the prefabricated steel structure housing has been vigorously promoted by the state, and a wave of prefabricated steel structure housing has set off in the market, and major companies have entered this field one after another. The prefabricated steel structure residence still upholds the advantages of the steel structure system itself, such as light weight, short construction period, and low environmental pollution. Prefabricated steel structure residences need to consider the conflict and matching between the structural system and the apartment type. In traditional design, the cross-section of steel columns and connecting beams is determined according to the design. However, in residential applications, the height of residential buildings is too high, resulting in too large cro...

Problems solved by technology

Prefabricated steel structure residences need to consider the conflict and matching between the structural system and the apartment type. In traditional design, the cross-section of steel columns and connecting beams is determined according to the design. However, in residential applications, the height of residential buildings is too high, resulting in too large cross-sections of components. Especially in the design of residential buildings, the thickness of the wall is generally not more than 200mm. If the size of the steel column is greater than 200mm or the size of the connecting beam is too high or too wide, it will lead to leakage of indoor components, which is a defect.

In the traditional design of residential buildings, if it is necessary to ensure that the indoor steel structural members do not leak, it is generally necessary to make a steel frame-support system, but when the floor is too high or the seismic fortification intensity is too high, it is necessary to use a steel frame-concrete shear wall structure system, which will increase the difficulty of construction and increase the construction period
