Description

Composite heat-insulation outer wall structure of hollow wall

Technical Field

The utility model relates to an utilize the compound incubation outer wall that industry by-product gypsum was made as the raw materials and was founded with the assembled means, especially a cavity wall body compound incubation outer wall structure.

Background

The annual production amount of industrial byproduct gypsum in China is about 1.84 hundred million tons, and the accumulated stockpiling amount exceeds 5 hundred million tons. But the comprehensive utilization rate of the newly increased production amount is only 48.1% every year, and the unused part can be only stocked in the open air. A large amount of gypsum waste residues are piled up, namely, a large amount of land is occupied; secondly, the investment of a storage yard is large, the operation cost is high, and the volume of the storage yard and the anti-seepage treatment requirement of the foundation are strict; thirdly, precious sulfur resources are wasted; and the contained acidity and other harmful substances are easy to cause pollution to the surrounding environment, and are not qualified with the environmental protection policy advocated by the state. However, the industrial byproduct gypsum is an important regenerated gypsum resource, the main component of which is calcium sulfate (CaSO4 & 2H2O), is an excellent cementing material, has the technical characteristics of early setting and quick hardening, fire resistance and energy conservation, is harmless to human bodies, and is suitable for being used as indoor decorative materials including wall materials. But at present, the cement retarder, the paper-surface plasterboard and the like are mainly used, the utilization amount tends to be saturated, and the rising space is limited. Therefore, the development of gypsum as an industrial by-product for use in other fields of building materials is urgently needed.

At present, the country advocates assembly type building house technique vigorously, including assembled concrete structure, assembled steel construction, assembled timber structure to require that the non-bearing enclosure wall of building adopts non-masonry technique and enclosure wall and heat preservation, thermal-insulated integration. The known non-masonry type enclosure wall comprises various medium and large plates, curtain walls, wood frameworks or light steel framework composite walls and the like, and meets the requirements of factory production, field installation and dry construction.

The spray-built gypsum composite wall is a new technology developed by my department and is mainly used for non-bearing internal partition walls. As an assembly type technology, if the spray-built gypsum composite wall is only made on the inner partition wall, and the part of the peripheral retaining wall requiring water prevention is additionally built, the construction management is inconvenient. In addition, building energy conservation is a mandatory standard in the field of buildings in China, and the existing energy-saving mode of wall bodies in China is mainly to install a heat-preservation energy-saving system on the outer side or the inner side of an outer wall. The high-efficiency heat-insulating material has low strength, is inconvenient to use on the inner side of the outer wall, is easy to crack and fall off on the outer side of the outer wall, has insufficient fireproof grade, is easy to catch fire and threatens lives of residents.
