Research On Application Of Resistograph For Wood Component Checking Of The Ancient Architecture

Resistograph is portable and simple to operate, and has high checking scale and veracity, which has made it be the most effective equipment to check the wood component of the ancient architecture. It is very important and necessary to research in-depth how the factors to influence the result of resistograph, and to form a full resistograph testing technique for the checking of the wood component of the ancient architecture.Density,moisture and resistance of the samples of new Korean Iarch,new Chinese white poplar,new common China-fir,old Korean larch,old Korean pine and old machilus were tested in this paper, and time,density,moisture and species influencing the results of resistograph are received. The results of the experiment indicates: time does not influence the result of resistograph obviously; density influences the result of resistograph obviously, the rules that moistrue influences the result of resistograph have never been founded; the species influence the result of resistograph, comparing denstiy, however, it do not influence the result of resistograph obviously.Besides, this paper described detailed how to use the results and the profile of resistograph to check wood component of ancient architecture in the open air,including of estimating density of wood component, bundle orientaion of the big diameter pilar, judgement of hollow position and rotted areas, judgement of wormhole and crack of wood compoment and primary differentiation of common used species in ancient architecture etc. This paper also introduced how to deal with the circumstance and how to use the results of resistograph in every checking and how to treat with the last results.[fig. 35,tab.19,ref. 58, for. 2]...
