APPLIED TECHNOLOGY OF EXTERIOR INSULATION SYSTEM FOR OUTER-WALL WITH POLYSTYRENE BOARD AND STEEL-PLASTIC PLUGGING BOLT IN CAST-IN-PLACE CONCRETE FORMWORK

The exterior insulation system for outer-wall with polystyrene board and steel-plastic plugging bolt in cast-in-place concrete formwork is composed of the polystyrene insulation board,anti-crack polymer mortar layer and finishing coat.Major construction processes are as follows: steel binding,polystyrene board installation,inserting steel-plastic plugging bolt,formwork installation,pouring concrete,formwork demolition,placement of steel plate network coated with Zinc,plastering anti-crack polymer mortar and sticking ties.Due to its safety,reliability,durability and considerable cheap,this system may be widely used for external wall's exterior heat insulation in the future.
