摘要:
针对装配式混凝土构件轻量化发展需求，将普通混凝土叠合板与砂加气混凝土材料相结合，提出一类轻质叠合板。为研究该类轻质叠合板的受弯性能并建立其弯曲刚度计算公式，通过四点弯曲试验分析预制底板材质、配置桁架钢筋和设置高延性混凝土衬板对叠合板破坏形态、抗弯承载力、弯曲刚度等受弯性能的影响；基于试验结果提出了适用于该类轻质叠合板在不同受力阶段的短期弯曲刚度计算公式。结果表明：桁架钢筋有效提高了轻质叠合板的叠合面抗剪能力和极限抗弯承载力；预制底板中分别添加0.4%碳纤维和0.4%玄武岩纤维且不设置高延性混凝土衬板时，叠合板的弯曲刚度和承载力均得到不同程度提高，但碳纤维增强效果更明显；预制底板设置高延性混凝土衬板时，碳纤维和玄武岩纤维对叠合板弯曲刚度和承载力的影响差异较小；对该轻质叠合板受弯性能的影响由大到小依次为桁架钢筋、纤维、衬板构造；所建立的短期弯曲刚度公式计算结果与试验结果吻合较好。
Abstract:
In response to the demand for lightweight development of prefabricated concrete components, a type of lightweight composite slab was proposed by combining ordinary concrete composite slabs with sand aerated concrete materials. In order to study the bending performance of this type of lightweight composite slab and establish its bending stiffness calculation formula, four point bending tests were conducted to analyze the effects of prefabricated bottom plate material, truss steel bar configuration, and high ductility concrete lining on the failure mode, flexural bearing capacity, bending stiffness, and other bending properties of the composite slab. Based on the experimental results, a formula for calculating the shortterm bending stiffness of this type of lightweight composite slab under different stress stages was proposed. The results show that the truss steel bar effectively improves the shear resistance and ultimate bending capacity of the composite surface of lightweight composite slab. When 0.4% carbon fiber and 0.4% basalt fiber are added to the prefabricated bottom plate without setting high ductility concrete lining, the bending stiffness and bearing capacity of the composite slab are improved to varying degrees, but the carbon fiber reinforcement effect is more significant. When setting high ductility concrete lining for prefabricated bottom plates, there is little difference in the influence of carbon fiber and basalt fiber on the bending stiffness and bearing capacity of composite slab. The order of influence on the bending performance of the lightweight composite slab from large to small is truss steel bar, fiber, and lining plate construction. The calculation results of the established shortterm bending stiffness formula is in good agreement with the experimental results.
