Research On The Safety Performance Of A New Energy-saving Fireproof Insulation Board

With China’s rapid development of urbanization and the increasing scale of housing construction, building energy consumption maybe will have exceeded the industry, transportation and other industries and rank the first place, so it is necessary for building energy efficiency to implement as a national policy. Then technical safety issues such as the insulation board shedding phenomenon, durability problem, crack problem, construction quality problem, etc accompanied by the appearance of energy- saving materials, energy-saving insulation wall products. So in this paper based on the new composite insulation board , it is focused on the safety of this type of product.In the first part, the safety of the new composite insulation board are studied and designed a series of related test, such as plane bearing strength, bond strength, compressive strength, flexural strength, hanging point bolts shear strength and tensile strength, Local compression strength of the wall, tensile strength of masonry with bolt through and hanging system strength. The results show that in the satisfaction of basic processing technology and construction requirements, the safety of the composite insulation board can be guaranteed.In the second part with the finite element analysis software ANSYS, several factors such as boundary condition, strength of masonry, height to thickness ratio, tie bar spacing are took to analysis the overall performance of the wall, included analysis the plane bearing strength, the stress and strain distribution, displacement, crack morphology . And the results show that increasing masonry strength, reducing the height to thickness ratio and tie bar spacing, and making a good close connection between the wall and the boundary around can improve the bearing capacity of the out-of-wall, and the factor height to thickness ratio is the most effective.Finally, comparatively analysis the similarities and differences of finite elements results and text results, then some proposals to practical projects and research new prospects are given.
