Description

 Fabrication self-insulation wall counter-removing preparation technology

 [0001] The present invention relates to the field of building materials technology, and in particular to a field of manufacturing, design and installation of a new type of fabricated wall.

 Background technique

 [0002] As the largest developing country, China's energy consumption per unit of GDP is more than twice the world average. In the face of increasingly severe energy security, the country is vigorously promoting energy conservation and emission reduction in various fields. Building energy consumption accounts for 20~30% of China's total energy consumption, so building energy efficiency is particularly important. The latest building energy efficiency standards are 75% energy efficiency standards in the northern regions such as Beijing, Tianjin, Shandong, Hebei, Xinjiang and other provinces. In most areas, urban residential buildings are 65%, and in very few areas 50%. Due to the late development of building energy efficiency in China, all aspects are not mature compared with developed countries in Europe and America, and energy-saving technical measures and standards are relatively backward. However, in general, ultra-low-energy buildings and green buildings are the development trend of China's buildings.

 [0003] Ultra-low-energy buildings are commonly referred to as passive buildings in the country, that is, buildings that do not require active heating and air conditioning or that maintain a comfortable indoor thermal environment with very low energy consumption. Passive building requires the building's external protection structure to have excellent insulation effect and airtightness. According to the current passive construction situation, the organic insulation material polyurethane or polystyrene foam with the best insulation performance is used as the insulation structure. More than 15cm, and the use of vacuum insulation insulation board, the total thickness of less than 6cm can meet the insulation needs of ultra-low energy buildings.

 [0004] Prefabricated buildings are the mainstream direction of engineering construction, that is, the construction of houses is like the production of cars, and the construction mode of factory prefabricated production and on-site assembly is fully implemented. However, at present, the prefabricated wall adopts a sandwich type structure, which is a structure in which a 5-8 cm thick concrete slab outside the heat insulating board is connected to the concrete of the main structure by a connecting member passing through the heat insulating board, and the structure of the sandwich is constructed. There are cumbersome production, high cost, low safety system, and the joints for fixing the outer 5-8cm thick concrete slabs are not implemented. The quality is difficult to guarantee, and a large number of cold bridges are formed. At present, all rely on imports, and the cost is high. No, the current assembly-type buildings are difficult to promote, and the incremental cost remains high.

technical problem [0005] For the assembled wall panel of the above sandwich structure, the present invention proposes to produce a fabricated self-insulating wall panel by the process of insulating the decorative panel, and cancels the connecting member of the outer panel in the original sandwich structure and the inner and outer joints. The cost has dropped drastically, increasing production efficiency, reducing the weight of buildings, and providing a guarantee for the promotion of prefabricated buildings on a large scale.
