Fabricated multi-limb steel column-simple support concrete board residential building structure system and construction method thereof

Abstract

The invention provides a fabricated multi-limb steel column-simple support concrete board residential building structure system and a construction method thereof. The residential building structure system comprises vertical bearing units, transverse bearing units and prefabricated slabs. Each vertical bearing unit comprises a vertical bearing section or is formed by vertically and sequentially butt-jointing a plurality of vertical bearing sections. In short, the fabricated multi-limb steel column-simple support concrete board residential building structure system is simple in construction andhigh in reliability, a large number of reinforcing bar projects in a construction site are avoided, and the construction efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to an assembled multi-leg steel column-simply supported concrete board residential structure system and a construction method thereof. Background technique [0002] At present, my country's steel structure buildings account for less than 10%, which are mainly used in industrial plants, high-rise commercial buildings and public buildings. There are many factors that restrict the promotion and application of steel structure buildings in China, including some technical problems at the structural level, for example: 1. Steel structure buildings are mostly frame structures, and there are problems with exposed beams and columns in residential buildings; 2. In the construction process There are a large number of beam-column-bracing connections in the main structural components. The existence of these connection nodes puts forward higher requirements on the precision of the...

Problems solved by technology

There are many factors that restrict the promotion and application of steel structure buildings in China, including some technical problems at the structural level, for example: 1. Steel structure buildings are mostly frame structures, and there are problems with exposed beams and columns in residential buildings; 2. In the construction process There are a large number of beam-column-bracing connections in the main structural components. The existence of these connection nodes puts forward higher requirements on the precision of the factory prefabrication and on-site hoisting of the components, and also limits the assembly speed of the main structure to a certain extent. ;3. The floor slabs of steel structure buildings have various forms, but they all need to be bound with on-site steel bars, and there is a problem of complicated connection with the main structure, which is also an important factor that limits the efficiency of steel structure assembly construction; 4. Enclosure walls and steel structures The main body does not match, it is difficult to reduce the thickness of the outer wall and save indoor space while realizing the building function of the enclosure wall; 5. The on-site installation of the enclosure wall creates gaps between the main structure and the post-processing It has brought a lot of problems to the construction, and also brought hidden dangers to the anti-seepage and anti-crack of the enclosure wall.
