Multilayer cold-formed steel integrally prefabricated house and splicing method thereof

Abstract

The invention discloses a multilayer cold-formed steel integrally prefabricated house and a splicing method thereof. The house comprises column modules, wall body modules, prefabricated floors and connectors, wherein vertical house connection is carried out on the column modules through column joints, column connectors, middle columns and connection wallboards, and concrete is poured in a cavity formed by the column connectors; and the column modules are transversely connected with the wall body modules through connection guide rails, connection wallboards, beams and beam connectors, so as to form an overall house framework. The multilayer cold-formed steel house structure is divided into three parts: the column modules, the wall body modules and the prefabricated floors, the three parts are connected in an integrally prefabricated manner through the connectors, all the modules are prefabricated in the factory, transported to the site and then constructed through mechanical hoisting, and only the concrete pouring stage after the column splicing has a fraction of wet operation at the construction site, so that the construction process is simple and convenient.

Description

technical field [0001] The invention relates to an integrally assembled building structure, in particular to an integrally prefabricated assembled cold-formed steel house structure, which belongs to the technical field of civil engineering. Background technique [0002] At present, my country is in the stage of high-speed urbanization and industrialization, and also in the stage of industrial structure adjustment and transformation. Traditional building structure systems and construction techniques not only have a large demand for natural resources and put enormous pressure on the natural environment, but also require a lot of on-site construction, which is costly and inefficient. In 2013, the General Office of the State Council of the People's Republic of China issued the "Green Building Action Plan", proposing that my country will vigorously develop green and energy-saving building structures, and is actively exploring new green building structure systems. In addition, in...

Problems solved by technology

In addition, the installation process of each wall panel and frame involves the installation of hundreds of screws, all of which require workers to operate, and the work gauge is large; when multi-layer structure construction is carried out, the installation of outdoor wall panels requires the construction personnel to operate technically. High, and there are certain construction risks, and the cost of personnel safety and security is high

In the existing multi-layer cold-formed steel structure technology, most of the side columns adopt cold-formed steel split sections or steel tube concrete columns. Load bearing requirements of steel structures

On the other hand, concrete-filled steel pipe columns generally use on-site grouting. A large number of wet operations will not only prolong the construction period, slow down the construction progress of the structure, but also reduce the mechanical properties of the wall panels; A large number of wet operations on site have high requirements on the construction site and construction equipment, requiring a large amount of human resources for management and coordination, and the cost is relatively high
