(Photo 1). There was a correlation between nailwithdrawal and compressive strength in the trial test on decayed Lauan veneer bolt. (Fig. 2). At the other test, practiced with 41 bolts of 26 different Sulawesi wood species in our laboratory 1955, there were also good correlation among nailwithdrawal, specific gravity and compressive strength.(Fig.3). We can apply this portable nailwithdrawal tester for the decay tester of wood poles in the subway construction field., 農林水産研究情報センターで作成したPDFファイルを使用している。}, pages = {78--80}, title = {可搬型釘引抜抵抗試験器の試作}, volume = {9}, year = {1987} }
