Japanese style exterior panela. Rijihua exterior wall hanging board (Figure 16), the specification is 400*3000*thickness, the price is about 250~300 yuan/m2;b. Beixin Jinbang board, the specification is 400*3000* thickness, and the price is about 150-250 yuan m2.


The North American style siding is easy to install and does not require special pendants.The installation of hanging panels in Japan is complicated and requires special pendants.This is not the main problem, the main problem is:■Exterior panels can only be used in low-rise and multi-story buildings.■Due to cost control, multi-storey buildings in the world, especially multi-storey residential buildings, rarely use external panels.■Considering safety factors such as wind resistance, earthquake resistance, and resistance to falling off, external panels cannot be used in high-rise buildings.3. Japanese style ALC boardJapanese ALC prefabricated wall panels have achieved large format, bas-relief shape and decorative color, which is a real prefabricated building exterior wall product.

Technology, market, and brand prospects of prefabricated exterior wall systemsThe main technical features of the prefabricated exterior wall system used in high-rise residential buildings should, but are not limited to the following:■Prefabrication (a necessary condition for realizing residential industrialization);■Light weight (sufficient conditions for prefabricated construction);■Insulation (sufficient conditions for energy saving, environmental protection and green);■Aesthetic (sufficient conditions for architectural aesthetics);■Inexpensive (sufficient conditions for market promotion);■Safety (necessary conditions for construction and use, or basic conditions).At present, precast concrete, the so-called concrete slab system, can only meet the two conditions of prefabrication and thermal insulation; it cannot meet the four conditions of light weight, beauty, cheapness, and safety.The most important thing is: In order to achieve the thermal insulation effect of the prefabricated concrete slab, inorganic material (a high-strength fiber) connector is used to connect the concrete slabs on both sides of the EPS insulation material. Due to the instability of the material and the manufacturing quality, etc. Many problems are plagued, and some model projects have already experienced major safety hazards such as peeling off the outer panels.Only the light steel keel composite panel exterior wall system completely composites the 6 major technical characteristics of the prefabricated exterior wall system used in multi-high-rise residential buildings.
