Three pinch wall decoration materials more "light." As a decorative material itself is not load-bearing, and the need to "attach" to play a decorative role in the other load-bearing structure, if the weight is too large, will inevitably result in deformation of the load-bearing structure is too large, resulting in deformation of decorative material itself, affect the decorative effects; at the same time, excessive weight can also lead to the building under earthquake inertia is too large, too much self-respect to resist seismic effect, will cause an increase in the amount of construction steel main structure containing such structures are not economical, therefore, building exterior materials to light weight inevitable development direction. Exterior wall construction must meet energy requirements. China's building energy consumption accounts for 70% of the annual energy consumption in buildings, 70% of the energy is lost through the walls, so that energy-saving building wall is particularly important, according to China's current energy-saving regulations, new building exterior structure if it is not energy-efficient standards, will not be approved or acceptance, as the request has been enforced, which requires our facades must be designed and constructed in accordance with the new energy-saving insulation measures. Three-dimensional board wall decoration materials more "thin." Because the material thinning, thinning of the wall thickness along the same area of ??residential buildings, the use of light than traditional brick wall construction can increase the use of an area of ??about 8 to 11%, in line with China's development of land-efficient buildings direction; From another perspective, a 100 square meters of housing, more than the increase can be about 10 square meters floor area, in today's real estate prices, according to 5000 yuan per square meter prices, equivalent to 50,000 yuan of value-added, integrated economy benefits are considerable. Three-dimensional wall decoration board construction method to "dry work" direction. Traditional "wet work" decorative construction workers by skill level operation, a great influence on the process conditions, decorative quality can not be guaranteed, and the construction is very slow, the use of precast decorative dry operation method can greatly accelerate the construction schedule, such as: Paste tile average efficiency of 25 square meters / man-days, and the use of dry hanging facades average efficiency can reach 50 to 80 square meters / man-days, if we adopt Japan's advanced technology, efficiency can reach 150 to 200 square meters / man-days, is wet nearly ten times the job, so you can shorten the construction period rumored advance handover.
