Description
Technical Field
[0001] The utility model relates to the technical field of construction, and more specifically to a self-supporting ultra-low energy consumption frame structure filled thermal insulation exterior wall. Background Art
[0002] Global warming is a severe challenge to human survival and development. With the continuous growth of the global population and economic scale, the environmental problems and causes of energy use are becoming more and more recognized by people. It is not only the hazards of smog, photochemical smog and acid rain, but also the global climate change caused by the increase of carbon dioxide concentration in the atmosphere. These are all serious consequences of human use of fossil energy. The energy consumption of buildings in the process of material production, construction, use and demolition accounts for about 30% of the total energy consumption of the whole society, which is an important cause of global warming.
[0003] Countries around the world are vigorously promoting energy-saving buildings. The current energy-saving practices for frame structure buildings are based on the German utility model external insulation board thin plastering system. Its disadvantages are that it can only guarantee a working life of 25 years at most, and it is easy to catch fire and fall off. Quality accidents are frequent now. Another mainstream system is AAC board, but because its board width is only 600mm, cracks and leakage are prone to occur at the joints. Insulated exterior walls are common structures in frame structure buildings, but existing insulation exterior walls have problems such as unstable structure, insufficient insulation performance, and complex construction.
