Abstract
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.
