Construction method for cold-bent thin-wall light steel structure building

Abstract

The invention provides a construction method for a cold-bent thin-wall light steel structure building. The construction method comprises main body component construction, wall board construction, rooftruss construction, roof construction and exterior wall construction, wherein a light steel main body component is light-gage steel joist which is formed by cold-bending and forming an aluminum-coated zinc steel strip. According to the construction method provided by the invention, the aluminum-coated zinc steel strip is assembled from the cold-bent and formed light-gage steel joist, the assemblystructure shortens the construction period to a very great extent, a building process adopts dry-process operation, is free of wet-process operation, assembly is performed on a plant processing site,assembly can be accomplished through block-building type simple assembly, the construction period is short, and field assembly is time-saving and labor-saving; and quality and anti-seismic property of the cold-bent thin-wall light steel structure building are excellent than those of a conventional structure, so that management is convenient. The building uses an environment-friendly energy-savingmaterial, and a waste material can be utilized for a second time; the obtained roof is stable in structure, and is not liable to move for a long time; and the obtained exterior wall has a ventilatingfunction, so that moist gas is smoothly discharged, and indoor air is effectively circulated to form a circulating system with outside.

Description

technical field [0001] The invention relates to a construction method of a building, in particular to a construction method of a cold-formed thin-wall light steel structure building. Background technique [0002] Green building is to save various resources to the greatest extent within the entire life cycle of the building, meet the requirements of protecting the environment and reducing pollution, create a healthy, applicable and efficient living space for people, and make the building and nature live in harmony. Its purpose is to reduce the damage of the building to the environment, and to create the healthiest and natural living space on the premise of saving energy and resources. [0003] The prefabricated building refers to the main structural components of the building. It does not need to be fabricated on site, but is prefabricated in the prefabrication yard or processing factory, and transported to the site for lifting, installation, connection, etc., just like build...

Problems solved by technology

At present, there are some deficiencies in the existing mud walls and mortars: on the one hand, due to the simple coordination of the existing mortars and poor cohesiveness, the mud walls made of mud walls are poor in crack resistance, water resistance and airtightness, thus Causes problems of cracking, holes and weathering drop of the mud wall; on the other hand, due to the low strength of the existing mud wall and weak resistance to rain erosion, it is easy to cause the wall to deform due to erosion, etc.
