【摘要】：徽州传统建筑木结构是徽州文化的代表,也是宝贵的古建筑遗产,是地域与人文的结合,是带给我们思考与借鉴的文化瑰宝。由于多种原因,造成徽州传统建筑木结构均出现不同程度的残损,需要对这些珍贵的历史遗产进行保护与修复,但是在保护维修中缺少相应的文字记录,也没有形成一套完整的加固修缮指导方法,因此需要对这些加固修缮方法进行系统地总结归纳。本文首先对徽州传统建筑木结构现状进行描述,系统地总结归纳了徽州传统建筑木结构各构件出现残损的原因,在研究进展中主要从中国古建筑的加固修缮方法总结、徽州传统建筑木结构加固修缮方法总结、国内采用新型材料加固修缮木结构方法总结、国外加固木结构方法总结四个方面。文中也给出了徽州传统建筑木结构加固修缮设计的编制程序,主要包括徽州传统建筑木结构的检测与可靠性鉴定,加固修缮设计方案的选择,加固修缮设计,加固修缮施工与验收共四个部分的内容。其次文中针对徽州传统建筑木结构的破坏形式,通过大量的实地勘验、向老工匠请教及遵循国家相关规范及标准,系统地总结了徽州传统建筑木结构木构架传统的加固修缮设计方法,主要包括柱、梁、枋、斗h1、小木作的加固修缮设计方法,文中也总结采用新型材料碳纤维增强复合材料(CFRP)加固徽州传统建筑木结构柱、梁的加固修缮设计方法,加固修缮设计方法已经成功应用于黄山市歙县许村敦睦堂、大墓祠、云溪堂,安徽泾县查济,祁门县馀庆堂古戏台,黄山市徽州区潜口镇的潜口民宅。文中最后针对加固修缮设计中梁枋水平裂缝深度及剜补截面的剜补形状进行了相关数值程序模拟,以验证梁枋水平裂缝深度的限值要求,并分析对构件截面承载力的影响,得到加固修缮设计方法中的水平裂缝深度限值是符合要求的,水平裂缝深度不同对截面承载力影响不同,同时得到剜补形状对截面承载力存在不同的影响,同等剜补体积下圆柱体加固效果要优于方体、三棱柱,方体要优于三棱柱,考虑实际施工的方便,加固修缮施工中建议采用方体,同时对于截面为多面体的要避免出现尖角,以免产生应力集中现象。本文的研究成果可为徽州传统建筑加固修缮设计与施工提供技术参考,也为其他地区传统建筑的加固修缮提供一种借鉴。
[Abstract]:The wooden structure of Huizhou traditional architecture is a representative of Huizhou culture, a precious ancient architectural heritage, a combination of region and humanity, and a cultural treasure for us to think and learn from. Due to various reasons, the wooden structures of Huizhou traditional buildings are damaged to varying degrees. It is necessary to protect and restore these precious historical heritage, but there is a lack of corresponding written records in the conservation and maintenance. There is not a complete set of reinforcement and repair guidance methods, so it is necessary to systematically summarize and summarize these reinforcement and repair methods. Firstly, this paper describes the present situation of wood structure of Huizhou traditional architecture, systematically summarizes the reasons for the damage of each component of the wood structure of Huizhou traditional architecture, and summarizes the methods of strengthening and repairing ancient buildings in China in the research progress. This paper summarizes the methods of strengthening and repairing wood structures in Huizhou traditional buildings, the methods of strengthening and repairing wood structures with new materials in China, and the methods of strengthening wood structures in foreign countries. This paper also gives the program of strengthening and repairing the wood structure of Huizhou traditional building, mainly including the inspection and reliability appraisal of the wood structure of the traditional building in Huizhou, the selection of the design scheme of the reinforcement and repair, the design of the strengthening and repairing, and the design of the strengthening and repairing. Reinforcement and repair construction and acceptance of a total of four parts of the content. Secondly, according to the destruction form of traditional building wood structure in Huizhou, through a large number of on-the-spot inspection, the paper consults the old craftsman and follows the relevant national norms and standards. This paper systematically summarizes the traditional design methods of strengthening and repairing wood frame of Huizhou traditional building, including column, beam, Fang, Dou H1 and small wood. This paper also summarizes the design method of strengthening and renovating the beams of traditional Huizhou building with new material carbon fiber reinforced composite material (CFRP). The design method of strengthening and repairing has been successfully applied to Xucun Motun Tang and Tomb Temple in Shexian County, Huangshan City, China. Yunxi Tang, Zha Ji County, Anhui Province, Qimen County Yuqing Tang ancient stage, Huizhou District, Huangshan City, the town of potential mouth residential. At the end of the paper, the numerical simulation of Fangfang horizontal crack depth and gouging out section shape of beam in reinforcement and repair design is carried out to verify the limit requirement of Fangfang horizontal crack depth, and to analyze the influence on the bearing capacity of member section. The limit value of horizontal crack depth in reinforcement and repair design method is obtained. The influence of horizontal crack depth on section bearing capacity is different. At the same time, it is found that there is different influence on section bearing capacity by gouging out and filling shape. At the same volume, the reinforcement effect of the cylinder should be better than that of the square, and the triangular prism and square should be superior to the triangulation. Considering the convenience of practical construction, it is suggested that the square should be adopted in the reinforcement and repair construction, and at the same time, for the polyhedron section, the sharp angle should be avoided. Avoid stress concentration. The research results of this paper can provide a technical reference for the design and construction of the strengthening and repairing of Huizhou traditional buildings, and also provide a reference for the strengthening and repairing of the traditional buildings in other areas.
