According to the excellent structure of the beetle elytron plate (BEP), a new type of bionic prefabricated wallboard with vertical trabeculae and honeycomb walls (the vertical trabeculae beetle elytron plate: VBEPsc) was proposed. The relationships between the main structural parameters, including the concrete frame thickness (T), honeycomb wall thickness (t), trabecula number (N) and trabecular radius (R), and the performance of the VBEPsc were analyzed. In addition, to improve the mechanical and insulation performance of the VBEPsc, an initial optimal design was determined. The results showed that 1) in addition to the mechanical properties of the VBEPsc being mainly affected by T, as is known, N had an apparent impact on the stiffness of the VBEPsc; the insulation performance was affected greatly by T, N, and t. 2) Under the given conditions, the mechanical properties of the optimized VBEPsc met the requirements for bearing capacities and serviceability; The insulation performance of the optimized VBEPsc met the requirements for self-insulating walls of category II buildings in areas that are cold in winter and hot in summer. In addition, a double-layer mold and complete production technology for VBEPsc were proposed. These works started a discussion for the application of such prefabricated wallboards.

基于机械和热绝缘性能的垂直小梁甲壳虫Elytron板结构参数的优化

根据甲壳虫电子板的优良结构,提出了一种新型的具有垂直小梁和蜂窝壁的仿生预制墙板(垂直小梁甲虫电子板:VBEP sc)。分析了主要结构参数之间的关系,包括混凝土框架厚度(T),蜂窝壁厚度(t),小梁数(N)和小梁半径(R)以及VBEP sc的性能。另外,为了提高VBEP sc的机械性能和绝缘性能,确定了初始的最佳设计。结果表明:1)除VBEP sc的力学性能众所周知,N主要受T影响,N对VBEP sc的刚度有明显影响;绝缘性能受T,N和t的影响很大。2)在给定条件下,优化后的VBEP sc的机械性能满足承载能力和可维修性的要求;经过优化的VBEP sc的隔热性能满足了在冬季寒冷和夏季炎热的地区对II类建筑物的自保温墙的要求。此外,还提出了用于VBEP sc的双层模具和完整的生产技术。这些工作开始讨论这种预制墙板的应用。
