Description

Technical Field

[0001] The utility model belongs to the field of concrete component preparation, and in particular relates to an assembled concrete component. Background Art

[0002] my country is vigorously promoting the transformation of traditional buildings to industrialized buildings. In traditional buildings, most of the work needs to be completed on site. Problems such as long construction period, serious environmental pollution, large stockpiling site, and shortage of construction workers have become barriers to the progress of the construction industry. Although prefabricated buildings have advantages in terms of construction, there are still some problems that cannot be ignored, such as the reliability of the vertical nodes of the PC structure, cracking and water leakage of the steel and composite structure enclosure walls, and they are usually expensive. Although the steel structure has a more reliable node structure and its construction quality is easy to guarantee, the steel structure itself has poor sound insulation and heat preservation, low rigidity and poor comfort, and requires additional fire prevention and anti-corrosion treatment. This is a difficulty that must be overcome in residential buildings. The steel-concrete composite structure has the advantages of both structures. Most of its main body is covered with concrete, and it has the same connection nodes as the steel structure. It perfectly overcomes the shortcomings of the steel structure and the PC structure, but it still has the problem of high steel consumption. Utility Model Content
