摘要/Abstract

摘要： 村镇传统民居的屋面系统多为坡屋面系统,但传统坡屋面系统施工复杂,安全性较差,保温不足,已不能满足建设新农村的需要,现设计一种新型钢丝网架瓦形保温屋面板来替代传统的坡屋面系统。本文从屋面板的原材料、瓦形、结构出发,选用纤维水泥基材料作为基材,钢丝网架保温复合板作为保温层,采用Abaqus软件根据现有的瓦形建模,设计出鳞形瓦屋面板、波形瓦屋面板和筒形瓦屋面板。对以上三种瓦形屋面板进行模拟抗弯计算,选出具有最优力学性能的瓦形制作钢丝网架瓦形保温屋面板。本研究制作的屋面板尺寸为4 500 mm×835 mm×185 mm,自重为159 kg/m²,传热系数为0.45 W/(m²·K)。通过三点抗弯性能测试,在4 020 mm跨距下,该屋面板所能承受的最大载荷为8.70 kN,实际测试弯矩为8.74 kN·m。基于装配式思想制作的新型钢丝网架瓦形保温屋面板具有优良的力学性能和保温性能,为特色传统村镇坡屋面系统的研究提供参考。

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
