[Abstract]:Building energy saving is an important part of energy saving and emission reduction in China. Shale sintered insulating block is a new type of wall material recently studied and produced in our country. This product makes full use of the abundant shale resources in China. In terms of production resources, the purpose of energy conservation is realized, and it has good thermal performance. The single wall material can meet the requirements of building energy saving design standard. As a sub-content of the research and application of shale-sintered insulating block masonry structure, this paper mainly includes the following contents:. 1) according to shale sintered insulating block and its wall, the heat transfer coefficient is calculated by theoretical calculation and simulation, and the one-dimensional steady heat conduction process of the block and wall is analyzed by finite element analysis software ANSYS. The theoretical value of the heat transfer coefficient of the block and the simulated value of the wall heat transfer coefficient are calculated respectively. Based on the heat transfer coefficient, the heat transfer resistance, heat transfer coefficient, thermal inert index, inner surface and interior temperature of shale sintered insulating block wall are measured. The surface heat storage coefficient and its thermal stability were analyzed and studied. 3) the steady-state heat transfer of three kinds of wall insulation forms is simulated and analyzed by finite element analysis software ANSYS, which shows that shale sintered insulating block wall has advantages over composite wall in building energy conservation and engineering application. 4) the heat transfer of each heat bridge of shale sintered insulation block is simulated and analyzed by finite element analysis software ANSYS, and the thermal insulation structural measures to reduce the energy consumption of thermal bridge are put forward. According to the structural characteristics of shale-sintered insulating block wall, the reasonable calculation and design of its thermal insulation structure are carried out, and the concept and basic method of heat preservation construction technology at hot bridge are put forward. Through the theoretical analysis and experimental study on the wall thermal performance of shale sintered insulating block, it can be seen that shale sintered insulating block has better thermal performance than other wall materials. It is of great significance to improve the thermal insulation and energy saving performance of buildings. The conclusion of this paper on the structure technology of shale sintered insulating block wall also provides an important reference for the popularization and application of shale sintered insulating block masonry structure.
