Description
Technical field
The invention belongs to building field, and in particular to a kind of preparation method of light insulating wall.
Background technology
With the improvement of people ' s living standards, develop all along the direction of skyscraper in city and part district, it is existing
Reinforced concrete frame structure typically is being used when building body is built, while constituting wall using the ash bricks of lightweight, is working as Lou Tijie
Structure still carries out the decoration of external and internal wall after the completion of making.The exterior wall of building building body is typically built using concrete or building block now
Build, with cement mortar it is floating after, in exterior wall using the organic plastics plate thin plastering heat-insulation system such as styrofoam, this mode is present not
Fire prevention, site operation of poor quality, low construction efficiency, it is long in time limit the problems such as, with science and technology progress, people design with hair
Soaked mud belongs to A grades of fire-protection rating as exterior-wall heat insulation fire-proof board, can exceed the heat insulation effect of expansion polyphenyl plate, but
Foam cement poor waterproof properties, and because its bulk density is low, cause intensity relatively low, integral rigidity poor performance, it is impossible to as
Composite.Therefore study a kind of fireproof heat-preserving wall that load bearing heat preserving is integrated in one meets market needs very much.Existing interior
The reason for brick wall, Chang Yinwei seif-citing rates, causes wall crazing, therefore, wall is formed integrally becomes one kind well
Settling mode.
The content of the invention
