Design of Prefabricated External Thermal Insulation System with Point Supported Horizontal Keel

摘要

Based on the basic thought of industrialized building, one prefabricated external thermal insulation system (ETIS) with point supported horizontal keel was designed in this paper. Bad support was fastened on the structural wall and horizontal keel was fastened on bed support. Then panel was fixed on horizontal keel by interdigitated cards and moreover thermal insulation material was fastened on the structural wall independently. ETIS has the ability to adjust the three-dimension and angle. The installation of panel could not only be invisible, but also be disassembled independently. The test result indicated that weathering resistance could meet the requirements of relevant standards and the maxima of wind resistance could be up to -6300Pa. In addition, panel deformation performance, air impermeability and water tightness could reach grade 5, grade 4 and grade 5, respectively.
