Study on Steel Wire Grid Tile Insulation Roof Panel and Its Bending Resistance

Abstract

Abstract: The roof system of traditional houses in villages and towns is mostly slope roof system. The traditional slope roof system has complex construction, poor safety and insufficient thermal insulation, which can not meet the needs of building a new countryside. A new type of steel wire gride tile insulation roof panel was designed to replace the traditional slope roof system. Starting from the raw materials, tile type and structure of roof panel, this paper selected fiber cement-based materials as the base material and steel wire grid insulation composite board as the insulation layer. According to the existing tile type modeling, Abaqus software was used to design the scale tile roof panel, wave tile roof panel and tubular tile roof panel. The three tile roof panels were simulated and calculated, and the tile type with the best mechanical properties was selected to make the steel wire gride tile insulation roof panel. The size of roof panel is 4 500 mm×835 mm×185 mm, self weight is 159 kg/m², heat transfer coefficient is 0.45 W/(m²·K). Through the three-point bending performance test, under the span of 4 020 mm, the roof panel bear maximum load is 8.70 kN and the bending moment is 8.74 kN·m. The new steel wire grid tile insulation roof panel based on the assembly idea has excellent mechanical and thermal insulation properties, which provides a reference for the research of characteristic traditional village slope roof system.

Key words: roof panel, steel wire grid frame panel, tile type, heat preservation, Abaqus software, bending resistance
