ねじ込み式挟締器具を用いた摩擦接合性能に関する実験的研究

Abstract

An experimental study has been conducted for the strength and the behavior of frictional connection between steel plates by a vice made of high hardness metal screw bolts. There are some difficulties to connect steel members by bolts, because the connection by the bolts needs to make accurate holes for the bolts. On the other hands, the vices are very convenient connecting devices for steel members, but there are uncertainties to use the vice for building structure contemporary due to the relaxation of the joint under large deformation, repetitive load and long term periods. A simple tensile test has been conducted to investigate the basic performance of the connection of the vice. Also cyclic loading test and relaxation test have been done to check the long term properties of the vice. The test results show that the connection by the vice possesses sufficient structural properties as good as normal joint by bolts.
