Built-in steel column in steel shear structure post-pouring section and pouring method thereof

Abstract

The invention discloses a built-in steel column in a steel shear structure post-pouring section and a pouring method thereof. The built-in steel column comprises a hollow column body; a main beam node, a column wall node and a pouring channel are formed in the column body; the main beam node is arranged on the column body; the design elevation corresponds to the position of a shear wall steel beam node; the column wall node is arranged in a position where the column body corresponds to a wall column node of a shear wall; the pouring channel is through inside and outside from top to bottom and is arranged on the column body. The pouring method comprises the following steps: pouring concrete into a post-pouring section node through a conveying pipe and the pouring channel by adopting a pouring funnel; vibrating while pouring, so that the post-pouring section node and the shear wall are condensed into an overall wall surface with a flush surface. The built-in steel column is connected with an exposed reinforcing steel bar of the shear wall, so that after the column body and the reinforced concrete shear wall are condensed into a whole, the aseismic strength of a whole building is enhanced. The built-in steel column disclosed by the invention has the effects that the structure is simple, the in-place is accurate, the assembly speed can be increased, and the comprehensive cost can be reduced, and is suitable for a multi-rise assembled residential building system.

Description

technical field [0001] The invention relates to a structural part in the field of prefabricated residential buildings and a pouring method thereof, in particular to a built-in steel column in a post-casting section of a steel shear structure and a pouring method thereof. Background technique [0002] At present, there are two main types of prefabricated buildings: reinforced concrete shear wall prefabricated type and steel structure hanging panel prefabricated type. Among them, the reinforced concrete prefabricated type needs a large number of supports and supporting accessories to hold the wall during the construction process of wall panel assembly. The installation and initial fixation of the boards are complicated procedures, which directly affect the progress of assembly construction, and there are many amortization of labor, machinery and auxiliary materials, which poses safety hazards; steel structure hanging board assembly buildings have imperfect structural forms and ...

[0002] At present, there are two main types of prefabricated buildings: reinforced concrete shear wall prefabricated type and steel structure hanging panel prefabricated type. Among them, the reinforced concrete prefabricated type requires a large number of supports and supporting accessories to hold the wall during the construction process of wall panel assembly. The installation and initial fixation of the boards are complicated procedures, which directly affect the progress of assembly construction, and there are many amortization of labor, machinery and auxiliary materials, which poses safety hazards; steel structure hanging board assembly buildings have imperfect structural forms and installations. Walls and beams are separated, occupying indoor space, affecting the appearance, costly for fire protection coating, various types of pendants, difficult to manufacture and install, and high cost
