Description
Technical Field
The invention relates to an environment-friendly energy-saving building heat-insulation composite structure and a construction method thereof, belonging to the technical field of wall heat-insulation engineering.
Background
With the rapid development of economy in China and the improvement of the life quality of residents, the energy consumption is increased day by day. Among them, the energy consumption caused by the construction industry is very large. The building outer wall structure is used as a building outer protective structure, and can directly influence the internal energy loss of a building. Therefore, if the building outer wall has good heat preservation and insulation effects, the energy consumption can be obviously reduced, and the energy-saving target is realized, so that the sustainable development strategy of China is realized.
The building external wall thermal insulation generally comprises three types of external wall external thermal insulation, external wall internal thermal insulation and sandwich thermal insulation. The heat insulation in the outer wall not only occupies the using area of the building, but also can cause the phenomenon of 'heat bridge' inevitably, and has poor water resistance and air tightness, thereby being not beneficial to the protection of the building envelope structure. The sandwich heat preservation also easily generates a 'heat bridge', air convection is easily formed inside, the construction is relatively difficult, and the shock resistance is poor. In contrast, the external thermal insulation of the external wall can basically eliminate the influence of a thermal bridge, is favorable for better exerting the protection effect of the wall body on the outside and improving the water resistance and the air tightness of the wall body, and is widely applied. However, the insulation layer is arranged on the outer side of the wall body, and the environment is severe, so that the requirements on the performance and the structure of each material of the insulation system are strict.
At present, the building materials applied to the external thermal insulation of the wall mainly comprise inorganic materials and organic materials. The organic heat-insulating material mainly comprises polyurethane, a foamed polystyrene board, an extruded polystyrene board and the like, has the advantages of light weight, good processability, high compactness, good heat-insulating effect and the like, and has the defects of poor stability, easiness in combustion, high engineering cost and the like. The organic heat-insulating material mainly comprises expanded perlite, foamed concrete, rock wool and the like, and although the inorganic heat-insulating material has the advantages of good stability, high flame retardance, low cost and the like, the inorganic heat-insulating material seriously restricts the large-scale application of the inorganic heat-insulating material in the building industry due to the large dead weight and poor heat-insulating property.
In the existing construction technology of building external walls, cast-in-place, prefabricated walls or masonry walls are mostly adopted. Most of the templates applied in construction are wooden templates or steel templates. The template has low reuse rate and large material consumption, and increases the construction cost to a certain extent. In the existing technology related to the external thermal insulation of the wall body, the construction difficulty is high, the weather resistance and the seismic performance of the material are poor, and the service life of the wall body is seriously shortened.
As the largest ceramic producing country and consuming country in the world, China generates nearly 1000 million tons of ceramic waste every year, and the air quality and the land use area are seriously influenced. Therefore, if the solid waste ceramics are recycled, the solid waste ceramics are changed into valuables, so that the environmental pressure caused by the solid waste ceramics can be relieved, and the positive promotion effect on the sustainable development of the society can be achieved.
