In China, the total energy consumption of buildings in the total social energy consumption accounts for nearly one-third portion, while the heat transfer through the building envelope generating residential houses can reach two-thirds of the building use energy consumption. In the 21 st century, China put forward a new energy efficiency standards, and promote the rapid development of composite wall. Currently, the study of thermal insulation sandwich composite panels is still relatively small, especially how to properly troubleshoot connectivity issues between the inner and outer leaf wall: both to make composite panels have better overall performance of the force, but also to reduce the thermal bridges because the connection generated.This paper presents a new type of ceramic insulation sandwich composite concrete wall.Such wallboard by previously Styrofoam plates burrow, and then in the inner and outer sides of the pouring leaf wall panels, wall panels so that the inner and outer leaves can be filled by ceramic concrete burrow at the connected together. In this connection, not only the composite wall with overall mechanical performance, but also has good thermal performance.By ANSYS software to build a wall thickness of the inner and outer leaves of different models and 36 different communication radius, the model analysis of mechanical properties and thermal properties of linear elastic and elastic-plastic analysis. Under horizontal loads and wind loads, mainly analyzes the composite wall displacement and equivalent stress distribution, the impact of the distribution of the reinforced effect, as well as different leaf wall thickness and internal and external communication with different radii of their produce. By contrast, obtained under lateral loads, both inside and outside the wall thickness of the leaf contribution to the overall mechanical properties of the composite wall is greater than the radius of communication; under wind loads, the contribution of the inner and outer wall thickness of the leaves and the communication radius of the overall mechanical properties of the composite wallboard basically the same. Thermal Performance focuses on the influence of temperature distribution node includesa horizontal cross-sectional temperature distribution, and different leaf wall thickness and internal and external communication with different radii of their produce. By comparing the composite wall inner surface of minimum and maximum temperatures and found that thermal bridge effect is not obvious; contrast composite wall inside surface minimum temperature by the temperature field obtained by the specification and the calculated indoor dew point temperature, within the composite wall surface does not produce condensation. All calculated composite wall heat transfer coefficient, according to the existing thermal specifications can be obtained compound wall 1A,1B,2A and 3A can be used as part of the envelope outside walls; all models can be used as part of the envelope wall use.In this paper, the new ceramic concrete sandwich composite wall insulation with good mechanical and thermal properties, to meet the relevant regulatory requirements, can apply to have the insulation requirements envelopes.
