Description

Construction of energy-saving insulation layer for prefabricated exterior walls of prefabricated buildings

technical field

The utility model relates to the field of building assembly, in particular to an energy-saving and thermal insulation layer structure of a prefabricated outer wall of an assembled building.

Background technique

There are a variety of technical systems similar to the concrete structure of prefabricated buildings abroad, such as the German "Double-WallPrecast Concrete Building System", Australia's precast concrete assembly technology (NPC), Japan's PC and PCF (precast shear wall external formwork, Precast Concrete Form ) technology, American precast concrete shear wall panel structure (Precast concrete shear wall panel structure), etc.

At present, the standard provisions of many countries involve prefabricated structures, and there are principle provisions related to prefabricated concrete wall panel structures. Especially in the "Precast and Prestressed Concrete Design Manual" compiled by the American Precast and Prestressed Association (PCI), the application of precast concrete technology, material requirements, preliminary design methods of prefabricated structural systems, part design methods and components. Standardization, node connection form, impact of temperature and climate change, and fire protection requirements have been elaborated in detail.

The research and application of prefabricated housing structures in my country mainly focused on large-slab assembled residential structures during the 1970s and 1980s. The large-slab assembled residential buildings in Beijing built a total of 1.726 million m2 from 1959 to the end of 1984 , of which the high-rise (12-13 floors) is 48.9m2, and the multi-storey is 2.237 million m2, and the industry standard "Design and Construction Regulations for Prefabricated Large Slab Residential Buildings" (JGJ 1-91) has been compiled. However, many defects such as leakage and poor thermal insulation performance in the prefabrication of large slabs to the maximum extent and joint filling of exterior wall blocks were exposed during the promotion, which made large slab assembly houses from a certain amount of popularization to almost extinct.

With the promotion of my country's housing industrialization policies and the needs of housing technology development, housing technology progress has accelerated, and the research and practice of housing industrialization production in my country has entered a new period of development. The housing industry modernization pilot projects have been listed in many places. On the platform promoted by the state and supported by enterprises, people began to re-examine the prefabricated shear wall structure system suitable for high-rise residential buildings. way.

The prefabricated exterior wall decoration surface layer often adopts traditional construction technology, which cannot eliminate the temperature transmission and sound transmission very well, and cannot meet the real ultra-low energy consumption prefabricated building standards. At present, there are many prefabricated prefabricated construction projects in my country. , but to achieve a real energy-saving thermal insulation exterior wall system, the current existing technical level is still very difficult.
