Description

Technical Field

[0001] This invention belongs to the field of building structure and construction technology, and relates to a profiled steel sheet modular combination structure house and its construction method. Background Technology

[0002] Traditional low-rise buildings mostly use masonry structures, meaning the walls are typically made of brick masonry, and the floors and roofs are made of cast-in-place reinforced concrete slabs. This construction method involves a lot of wet work on-site, resulting in slow construction speed and easy material waste and environmental pollution. Later, reinforced concrete components for building structures developed rapidly. However, cast-in-place reinforced concrete structures usually require on-site reinforcement binding, formwork erection, concrete pouring, and then formwork removal, which requires a lot of on-site labor and a long construction period.

[0003] With the further development of urbanization and the increasing level of industrialization in the construction industry, in addition to the structural design and performance requirements of reinforced concrete components, higher requirements are also being placed on the component manufacturing process and the rationality of installation.

[0004] To address the problems associated with traditional construction techniques and existing prefabricated construction techniques used in low-rise and high-rise buildings, and to improve the construction methods for these buildings, it is necessary to propose effective construction technology solutions that are structurally sound, easy to construct, and cost-effective for low-rise and high-rise buildings.
