The system features that unique cement mate, insulating adhesive, alkali-resistant glass reinforced grid, special cutting tools, grinding tools and toothed plastering tool are used. Its advantages are high quality, short construction period, low cost and saving energy by more than 50%.

Description

technical field [0001] The invention relates to a thermal insulation system, more specifically to an external wall thermal insulation system, and at the same time, the invention also relates to a construction process of the external wall thermal insulation system. Background technique [0002] The wall insulation system is an important technology that affects the quality and duration of building construction. Especially in cold areas, the use of a reasonable wall insulation system can not only shorten the construction period, improve construction quality, reduce heating costs, reduce environmental pollution, but also provide users with a more comfortable and warm living environment. Wall insulation systems vary widely depending on the insulation material used. Materials traditionally used in wall insulation systems include EPS (expandable polystyrene), foamed polyurethane, rock wool, perlite, etc., but EPS is the main one. There are four main ways to use EPS insulation: EP...

AI Technical Summary

Problems solved by technology

These four main methods have their own advantages and disadvantages. (1) The obvious defects of the external insulation of EPS (with steel mesh) are that it will form large cracks, there are thermal bridge problems, and the problems of traditional technology are more obvious; (2) EPS paste The method of external insulation can effectively solve the problem of large cracks and thermal bridges. The construction is more convenient and the process is reasonable, but it is difficult to solve the water content in the strong water-absorbing wall; (3) EPS internal insulation has the advantage of simple construction, but it cannot solve the problem of thermal insulation. Bridge problem, it is difficult to meet the "Civil Building Energy Conservation Design Standard", and the strength of the inner wall is limited, and the decorative pendant is difficult; (4) EPS sandwich wall is low in cost, but the construction is very difficult, the wall strength is limited, and it cannot overcome the heat bridge, it is difficult to meet the "Civil Building Energy Efficiency Design Standards"

Moreover, the plastering technology used in these traditional constructions requires a thickness of more than 20mm to ensure health preservation and curing, and it takes 21 days to dry, and the brick wall using traditional plastering technology has a high water content, although the surface contains water Up to the standard, but the water content of the wall is still high, so the 21-day health preservation period does not have good decoration conditions
