At present, the urbanization process is accelerated, the large-volume construction project lacks enough understanding on the green environmental protection problem, the development of the construction industry is restricted, and the development of the construction industry follows the principle of green high-quality development. The assembly type building is to improve the industrialization level of the building through an assembly technology, prefabricate components and carry out modularized assembly. The assembly type green building technology saves resources, reduces pollution, is convenient for cost control and construction management, and can meet the requirements of construction quality and the goal of sustainable development of green buildings.
The energy consumption of buildings in China is greatly increased year by year, so that the energy saving of the buildings becomes an important field for the development of the building industry in China, at present, the heat consumption of building enclosure structures accounts for more than one third of the energy consumption of heating and air conditioning of the buildings, wherein the wall accounts for the maximum density and accounts for 75-80% of the heat transfer and consumption of the enclosure structures. The assembled enclosure system is an important component of an assembled building, and the composite heat-insulation external wall board made of light, new and green novel materials can meet the heat-insulation and energy-saving requirements of an outer wall and becomes an effective means for realizing building energy conservation. The traditional single-material wall is difficult to meet the mechanical and high heat-insulation requirements at the same time, so that the composite wallboard is produced at the right moment. The composite wall is a composite wall formed by combining two or more materials, and the composite wall applied to an outer enclosure system of a building structure generally has the advantages of light weight, high strength, good heat insulation performance, fire resistance, water resistance, corrosion resistance, high production efficiency, convenience in assembly and the like. The external protective composite wallboard of the building structure has good heat insulation performance and needs to bear out-of-plane horizontal earthquake action, wind load or out-of-plane impact load, so that the research on the out-of-plane stress performance test of the composite wallboard is very necessary.
Since the middle of the 20 th century, cold-formed thin-walled lightweight steel structures have been widely used in developed countries. Compared with other types of steel structures, the widely cold-formed thin-walled section steel has the advantages of light self weight, high industrialization degree, high comprehensive economic benefit, capability of realizing assembly and the like, and is mainly applied to an external enclosure structure wallboard system integrating enclosure, heat preservation and decoration of an assembly type building. As a main matched part of the assembled steel structure system, the light steel keel wallboard has multiple functions of enclosure, heat preservation, decoration and the like.
The foamed ceramic is a light plate-shaped ceramic product with heat preservation and insulation performances, which is prepared by taking industrial solid waste or other mineral raw materials as main raw materials, adding an additive and a foaming agent and roasting and foaming at high temperature. The foamed ceramic not only adopts industrial waste residues, accords with the national policy of energy conservation and emission reduction, but also has the advantages of light weight, heat insulation, heat preservation, fire prevention, sound insulation and the like, is easy to cut and assemble, and is suitable for being applied to an assembled external enclosure structure system. How to scientifically and reasonably use the foamed ceramic plate for the external enclosure structure wallboard system integrating the enclosure, the heat preservation and the decoration of the fabricated building, how to safely and reliably combine the light steel keel and the foamed ceramic plate and how to realize the light wallboard integrating the enclosure and the decoration of the structure is a key technical problem which is very concerned and urgently needed to be solved in the engineering industry at present.
