Loading Apparatus for Bending Member

摘要

The present invention relates to a weight load device which is simply installed on a site using a wire rod such as a steel wire or a steel rod and an abutment test rod to test a structural performance of a bent structure such as a beam or a girder forming an upper structure of a bridge which supports bent weight, thereby easily loading weight required for the test on the bent structure. The weight load device (100) loading vertical weight on the bent structure (300) for a weight load test of the bent structure (300) includes a longitudinal abutment test rod (4) extending in a longitudinal direction; a plurality of transverse abutment test rods (3) extending in a transverse direction on an upper portion of the longitudinal abutment test rod (4); a weight-transferring wire rod (1) formed of a wire rod, having a lower end anchored and fixed to the ground and an upper end coupled to both sides of the transverse direction of the transverse abutment test rods (3), and transferring the weight applied to the transverse abutment test rods (3) to the ground; and a flexible jack device (2) disposed between the longitudinal abutment test rod (4) and the bent structure (300) at a lower portion of the longitudinal abutment test rod (4) and extended and shrunk to apply the vertical weight to the bent structure (300), wherein the force generated by the extending and shrinking of the flexible jack device (2) is applied as vertical downward weight to the bent structure (300).
