The Research On Experiment And Theoretical Analysis Of Insulation Composite Wallboard

This paper analyses mechanical properties of insulation composite wallboard by nonlinearfinite element software ANSYS.Firstly, referencing contrast test as the theoretical basis, simulating shear strength test andflexural capacity test of two kinds of insulation composite wallboard by ANSYS finite elementsoftware. One situation is that benzene board is placed on side,the other situation is that benzeneboard is placed in the middle. The experiment adopts the horizontal unidirectional gradingloading and three locations loading. Through the test, we can get load-displacement curve,displacement and stress equivalent graphs, cracking loads and ultimate load. Simulation resultsand test were compared. Analysis results show that failure shape, bearing capacity, thedeformation and crack development for polystyrene plastic board in the middle is slightly betterthan on the side, but not big change. Considering placing the polyphony board in middle position,that makes concrete thickness on both sides of the insulation wallboard structure system is thesame. Thereby, its construction is more convenient, feasible, and easier to get quality guarantee.Secondly, this paper simulats analysis on a proposed two kinds of new thermal insulationcomposite wallboard by ANSYS. And ontrasted analysising carrying capacity size of benzeneboard placed on both sides and placed in the middle. And load force-displacement curve graph,stress and displacement equivalence equivalent graphs of two kinds of structures are compared.Results show that bearing capacity of benzene board placed in both sides was improvedobviously, crack development later.Finally this paper makes a comparative analysis on the insulating performance and the marketprice of polyphony board and heat transfer coefficient lower polyurethane foam plastics,polystyrene foamed board.And having analyzed theory calculation on the thermal performanceof insulation composite wallboard with exemption dismantle. Results show that the insulationcomposite wallboard with exemption dismantle can meet application requirements, and energysaving effect is very good.The research results provide a reference for engineering application and further analysis ofinsulation composite wall structure.
