[Abstract]:According to the climate characteristics of summer heat and winter humidity and cold in Fujian area and the present situation of building energy consumption in this area, the concept of economy, energy saving and environmental protection, and improving the thermal comfort of houses are adopted. Research and development of composite insulation roof of EPS module in Fujian area. In this paper, the key problems such as structural integration of EPS composite roof slab, structural connection technology and mechanical properties are deeply studied by using the method of theoretical stress calculation and finite element simulation analysis. The main work is as follows: (1) by analyzing the shortcomings of the mechanical properties of the existing roof panels, the structural design of the new composite roofs is studied, and the thermal performance of the new composite roof panels is analyzed according to the characteristics of climate and energy consumption in Fujian. To determine the thickness of the composite roof slab. 2) in combination with the actual engineering requirements, 25 pieces of EPS module composite insulation roof board are established. The failure pattern and deflection performance of the composite roof slab are analyzed by using ANSYS finite element analysis software. The ultimate bearing capacity performance is simulated. 3) on the basis of the previous finite element ANSYS simulation, by changing the parameters such as span, section size, thickness and so on, the composite roof plate of EPS module is changed. To simulate the influence of these factors on the bearing capacity and deformation of composite roof slab. Main achievement: 1) by improving the structural design of the opening connection of the original module, a new type of EPS module is proposed, which improves the tensile strength between the EPS modules that are jointed with each other and makes the connection structure of the module stable. (2) according to the requirement of DBJ13-62-2014, the optimum thickness of EPS composite insulation roof in Fujian area is determined to be 80mm. 3) the mechanical properties of EPS module are analyzed by ANAYS finite element software. Under the limitation of not only suitable for roof, a new type of roofing board on EPS module is developed by changing the arrangement of span.
