Metal covering decorative board external thermal insulation connecting system
Technical Field
The invention relates to an external thermal insulation connecting system of a metal surface decorative plate and belongs to the technical field of building thermal insulation systems.
Background
The building field is the field with larger energy resource consumption and environmental impact, and the building energy conservation is the fundamental way of relieving energy shortage, improving the living condition of people, reducing the environmental pollution and promoting the sustainable development of economy. The energy consumption of buildings in China accounts for 46.7% of the total energy consumption of the whole society, only the energy consumption of the buildings in the using process accounts for 27.6% of the energy consumption of the whole society, and the proportion is continuously increased along with the acceleration of the progress of the urbanization strategy. The development of energy-saving buildings and green buildings by manpower becomes an important component of national energy conservation and emission reduction. The implementation of energy conservation of the enclosure structure is one of effective important ways for realizing the aim of energy conservation. At present, the wall body heat preservation in China almost completely adopts the external wall heat preservation technology, and accounts for more than 95% of the engineering application amount.
The external wall external insulation is an insulation method of placing an insulation layer outside a main wall material, and is the most widely applied insulation method at present; although the external thermal insulation technology of the external wall is developed rapidly in China, the traditional external thermal insulation system represented by pasting a thermal insulation board, plastering, insulating slurry composite thermal insulation boards, spraying hard foam polyurethane and the like has a plurality of problems in the popularization and application and engineering practice of many years, for example, the quality safety problems of hollowing, cracking, dropping, fire and the like frequently occur in the external thermal insulation engineering of the external wall, and great quality safety hidden dangers are brought to the engineering.
