Description
Technical field
The present invention relates to the engineering-built field, be specifically related to a kind of insulation construction system and construction method thereof that is applicable to the existing building masonry.
Background technology
The existing building of China, the especially building of building up before 2000, its energy consumption is about 2～3 times of new building, and storage is very huge again simultaneously for the dwelling environment difference.Residential building to only northern heating zone need reducing energy consumption in the end of the year 2000 just reaches 31.68 hundred million m according to statistics
2Therefore, along with China's economic development, under the new building total amount will the reality of sustainable growth, the reducing energy consumption of existing building will have crucial meaning to reaching of Chinese target for energy-saving and emission-reduction.Body of wall accounts for the volume maximum of space enclosing structure.Greatly account for 20% of building total amount of heat by the exterior wall dispersed heat winter; And absorb about the 3O% of heat for building total by the heat that exterior wall absorbs summer.Therefore, aspect the exterior wall heat preservation construction. answer the compound enclosed structure of first-selected exterior-wall heat insulation,, improve thermal resistance value, reduced heat bridge effect simultaneously, make the room temperature that in a comfort standard, keeps the long period with less energy with this wall heat transfer speed that slows down.
The existing building reducing energy consumption is the emphasis of the current builing industry energy-saving and emission-reduction of China, and practices well is to require to carry out external wall outer insulation according to " building energy conservation engineering construction quality standards of acceptance " GB 50411-2007.Usually make to stick with glue the method that connects, warming plate is sticked on the body of wall, or adopt steel wire or other materials that the mode on the body of wall is followed closely, hung over to warming plate.After the PROCESS FOR TREATMENT through the multiple tracks complexity, do outer the decoration again.The heat preservation energy-saving reforming technology of this existing body of wall, the work progress complexity, speed is slow and body of wall is easy to crack, hollowing.Insulation, heat-proof quality is relatively poor, fireproof performance is bad, the cost height, long in time limit, can not guarantee the safety of binding face tile, and the application life of this class exterior wall insulated structure short (25 years), quality problems will occur after two more than ten years, and produce maintenance cost, and the application life of building is generally in 50～70 years, the life-span in body of wall and house will be asynchronous like this, the external surface of buildings cracking takes place in the design life of being everlasting, quality problems such as peel off, do not have good heat insulation effect and influence attractive in appearance, in repair procedures, also can produce a large amount of building wastes, contaminated environment.
