EXPERIMENT ON FLEXURAL PROPERTIES OF PREFABRICATED LIGHT-GAUGE STEEL-CONCRETE COMPOSITE EXTERNAL WALL PANELS
-
摘要: 新型预制轻钢复合混凝土外挂墙板是一种结构保温一体化预制外挂墙体系统，以轻钢龙骨为骨架，以高性能混凝土板作为外面板与龙骨通过剪力钉连接，内填保温材料并辅以水泥纤维板为内面板形成一体化墙板，工厂预制，现场吊装，起到建筑外围护作用。通过对该组合墙板四点弯曲试验结果与有限元模拟结果的对比，得出了不同构造对组合墙板抗弯性能的影响规律。试验结果表明：该墙板具有良好的整体受力性能，墙体中的轻钢龙骨对整体的抗弯承载力贡献较大，可明显提高组合墙板的刚度。有限元模拟结果表明：增加混凝土厚度可以提高墙板整体受力性能，但提升幅度不大；为提高墙板保温性能而设置的保温层的厚度对墙板承载力有较大影响。Abstract: The new prefabricated light-gauge steel-concrete composite external wall panel is a new structural thermal-insulated external wall system, with light-gauge steel keel frame as its framework and the external boards of high performance concrete boards connected with the steel keel frame with studs. Thermal-insulated materials and cement fiberboards as internal boards were filled in. The wall panel could be prefabricated in plants and installed in project sites, and played the role of enclosure walls for buildings. Compared the results of the four-point bending tests and finite element simulations, the influence laws of different structural types on flexural performances of wall panels were obtained. Results showed that the wall panels had good overall mechanical properties; the light-gauge steel keel frame could significantly improve the stiffness of the composite wall panels. Besides, the simulation results by FEM showed that the thickness of concrete boards could slightly improve the overall mechanical properties of wall panels, and the thickness of thermal-insulated layer in wall panels had great influence on the bearing capacity of wall panels.
