Research on Mortise Nodes of Flat Steel, Carbon Fiber Reinforced Repair Method of Huizhou Ancient Residential Renovation

Abstract Huizhou ancient residential flat carbon fiber cloth mortice and tenon joints, repair and reinforcement design method is one of the hot spots in the present study of ancient architecture. According to the data collection and field research and then combined with the research on reinforcement repair method of ancient houses of Huizhou state mortice and tenon joints procedures, analysis of Huizhou ancient dwellings mortice and tenon joints forms of damage, summarizes the Huizhou ancient dwellings mortise and tenon joints the ability to check formula, and the Huizhou ancient residential flat mortice and tenon joints using the finite element method, the carbon fiber cloth reinforcement method is analyzed by numerical simulation. The study shows that by node force performance before and after the reinforcement of mortise and tenon mortise and tenon contrast, mechanical properties of the reinforced joints is improved obviously; damaged ancient dwellings mortise and tenon nodes through flat steel, carbon fiber cloth etc. a method for stabilizing after the renovation is meet the requirements of the standard. Based on the comparison of theoretical calculation and numerical analysis of the mortise and tenon joints of Huizhou ancient residential buildings, the calculation results are consistent, which verifies the feasibility of the flat steel and carbon fiber cloth reinforcement and repair design method, To provide reference for the restoration and protection of Liang Fang in Huizhou traditional architecture.
