Research On The Construction Documents Of Wooden Arch Bridge In The North Of East Fujian

Wooden arch bridge is the category with the highest technical content among traditional wooden bridges in China.More than 100 existing wooden arch bridges are mainly distributed in the mountainous areas bordering Fujian and Zhejiang,while there are 51 in the Ningde region in northeast Fujian,including 19 in Shouning.Shouning Bridge is known as the "hometown of wooden arch bridges in the world" due to its characteristics such as "the largest number,the longest single arch span,and the most up-to-date construction sequence.".At present,there are still a group of wooden arch bridge craftsmen active in the Ningde region of northeast Fujian.In the era of promoting traditional Chinese culture,wooden arch bridge construction is not decorated,construction technology civilization is continued,and construction custom culture is inherited.This study focuses on the stage process of the wooden arch bridge construction system,and takes the literature generated during the construction process of the wooden arch bridge as the research object.The specific research content includes the bridge construction agreement signed before the construction of the bridge,the design drawings drawn by traditional artisans during the construction,and the ink books written on the bridge roof and beam frame after the construction.Through field research,artisan interviews,and literature research during the three-year study period,the collected data on the construction of wooden arch bridges were collected and analyzed,and the construction literature generated at different stages of the construction of wooden arch bridges was placed within the overall framework of the construction of wooden arch bridges for research.The research contents and achievements showed that by systematically collecting and sorting out the bridge contracts of lounge bridge,it is classified according to the times and contents,focusing on the analysis of the characteristics and composition of the bridge contracts,and exploring its practical significance for the current construction of lounge bridge;Design pattern is the core component of lounge bridge’s construction technology.The design concept and method behind the1: 1 proofing of bridge arch and the rules for setting the structural dimensions of bridge houses can be understood as "cracks" in the construction of traditional buildings in China,which can open the door to the knowledge of traditional buildings in China.The ink calligraphy on the beam structure is not only used to publicize the information such as participants,details of donations and the time of bridge construction,but also has certain rules in the distribution of writing order,which is a concrete spatial cultural representation similar to Zhao Mu system.This research attempts to make academic contributions in the following three aspects:(1)systemically sort out,analyze and discuss the existing wooden arch bridge;(2)interpret and analyze the collected graphic data of wooden arch bridge design,summarize the design principles and construction practices of traditional craftsmen,and reveal the design thinking system of craftsmen;(3)analyze and interpret the collected ink book atlas of Shouning wooden arch bridge,and summarize the types The distribution pattern and its value connotation.By organizing and analyzing the literature on the construction of wooden arch bridges mentioned above,we aim to make some humble notes on the cultural and technological inheritance and evolution of wooden arch bridge construction,and also provide some reference for subsequent academic research by scholars.
