Description

Technical Field

[0001] The invention belongs to the field of industrialized building prefabricated exterior walls, and in particular relates to a steel-concrete combined energy-saving enclosure wall and an implementation method thereof. Background Art

[0002] In 2020, the Ministry of Housing and Urban-Rural Development, the Ministry of Science and Technology and other nine departments jointly issued the "Several Opinions on Accelerating the Development of New Building Industrialization", proposing to vigorously develop steel structure buildings. All components of steel structure residential products are rolled by industrialized and standardized procedures, which can reduce material and processing costs by 40%, reduce several construction links, shorten the construction period by 50% compared with traditional construction methods, greatly improve management and operation efficiency, and reduce comprehensive costs by more than 20%.

[0003] Through years of research and technical practice, my country has established a complete set of mature steel structure main body construction technology and supporting construction equipment, providing strong technical support for the development of building industrialization. However, in terms of steel structure enclosure, most of the steel structure projects in my country still use masonry brick wall structure for their exterior walls, which has slow construction speed, high construction cost, and poor energy-saving and thermal insulation performance. In order to improve the thermal insulation performance of the wall, secondary external insulation or internal insulation treatment is usually required, which greatly reduces the construction efficiency of steel structure buildings and increases time costs.

[0004] Therefore, developing a steel-concrete composite energy-saving enclosure wall suitable for steel structure building structures and its implementation method, which has integrated energy-saving insulation and enclosure functions, so that it can be produced in a prefabricated processing plant and transported to the construction site for rapid assembly, is of great significance to improving the level of industrialized construction of steel structure building projects.
