    1、 Performance and characteristics of composite insulation exterior wall panel system:






    The fabricated aerated concrete composite thermal insulation exterior wall panel system is an exterior wall enclosure system composed of composite thermal insulation exterior wall panel installed on the main structure, thermal insulation slurry leveling layer, plastering layer, finishing layer, and thermal insulation treatment measures for beams, columns or shear walls, which is referred to as composite thermal insulation exterior wall panel system for short.

    2、 Compared with the traditional exterior wall, the composite insulation exterior wall panel system has the following 10 technical advantages:






    1) Composite wallboard has excellent thermal performance






    The organic thermal insulation board is compounded on the base course of aerated concrete board, and the organic thermal insulation board is completely wrapped or covered with A-level fireproof thermal insulation slurry, which not only meets the requirements for the thermal performance of the wall in cold and severe cold areas, but also solves the problem of poor freeze-thaw resistance of aerated concrete and can not meet the technical index of freeze-thaw resistance specified in the technical standard for external wall external thermal insulation.






    2) The weight of composite wallboard is light






    It is only 1 / 6-1 / 4 of the prefabricated concrete sandwich wallboard. The requirements for lifting equipment during wallboard installation are low, and the installation accuracy is easy to control; At the same time, it also reduces the self weight of the structure and the cost of foundation treatment. It can give full play to the advantages of light self weight, high bearing capacity and good seismic performance of fabricated steel structure buildings, and reduce the project cost.






    3) It solves the problems of fire prevention and falling off of traditional external wall external insulation.






    There is no cavity between the structural layers of the composite wallboard, and a keyway is set on the surface of the insulation board, which increases the bonding area and biting force between the protective layer and the insulation layer, and ensures the connection safety between the structural layers by adding plastic anchor bolts to assist mechanical fixation; Both sides of the insulation board are made of non combustible materials ≥ 50mm thick, which solves the problems of poor fire safety and large fire hazards of the traditional external wall external insulation system.

    4) The node connection structure is simple and the production is convenient.






    The aerated concrete strip does not need to be provided with embedded parts, but is mechanically perforated and provided with sleeves on the strip produced by the normal process. The wallboard is connected with the main structure through sleeves and connectors, which has the advantages of simple structure and convenient installation. It solves the problems of complex production process and difficult manufacture of embedded parts in the aerated concrete strip, and also solves the problem of node thermal bridge in the conventional connection structure.






    5) Meet the requirements of factory manufacturing and assembly construction.






    Composite wallboard is a kind of integrated wallboard with thermal insulation and structure prefabricated in the factory. It is constructed by assembly method, which not only has high production efficiency and easy product quality control, but also conforms to the policy of vigorously developing prefabricated buildings in China.






    6) The treatment of slab joints is simple and the construction is convenient.






    A thermal insulation slurry leveling layer is set outside the composite wallboard, which can meet the requirements of wall leveling by adjusting the thickness of the slurry layer, which not only solves the problems of many strip joints and plate joint structure






    The utility model can deal with complex problems, and can also completely cover the panel joint caulking material, which improves the durability of the wallboard system.






    7) The purpose of building thermal insulation and the same service life of the wall is realized.






    The organic thermal insulation layer is located between the aerated concrete board on the inner side and the thermal insulation slurry layer on the outer side, which avoids the direct influence of ultraviolet radiation and fire damage, improves the durability of thermal insulation materials, and realizes the purpose of the same service life of the composite thermal insulation board and the main structure.






    8) Wide sources of raw materials.






    The main raw materials for composite wallboard production are rigid foam plastic insulation board (EPS, XPS, PU board, etc.), aerated concrete slab, rubber powder, vitrified microbead, alkali resistant fiberglass mesh cloth, plastic anchor bolt, etc., which are widely distributed.






    9) The production cost is low, the process is simple, and the product quality is easy to control.






    The composite insulation external formwork system has been popularized and developed mature in our province. The prefabricated aerated concrete composite wallboard production line only needs to upgrade the composite external formwork production equipment, with low production investment cost and broad application foundation. Composite wallboard production equipment has high degree of automation, low labor intensity, assembly line operation, high production efficiency and easy product quality control.








    10) Green environmental protection.






    Aerated concrete slab base is a green environmental protection material with a wide range of manufacturing materials






    It has the advantages of stable material, light weight, heat preservation, heat insulation and sound insulation, and has good machinability. It can be sawed, drilled, nailed and slotted, which solves the problems of nailing heavy objects on the wall and slotted pipeline layout; The composite thermal insulation exterior wall board adopts multi-layer structure design, and there is no noise and three wastes in the production process. The composite wallboard adopts the assembly dry method, which reduces the construction pollution and protects the ecological environment.
