Direct Tensile Strength Test Method of Filler between Precast Concrete Members

摘要

The present invention is based on the idea that the connection between the precast concrete members in the integrated structure by bonding the narrow gap between the precast concrete member and the member using a suitable filler sufficiently secures the bonding strength so as to exhibit appropriate safety against the external load (4) having a plurality of bolt mounting holes (3) formed in a square plate and a barrel mounting hole (7) formed at the center of the plate; An inner plate (5) formed with the same number of bolt mounting holes (3) as the front plate and having a barrel mounting hole (7) formed at the center thereof; A bolt (1) installed at a predetermined interval through the front plate (4) and the bolt installation hole (3) formed in the inner plate (5) at the same time; A nut 2 fastened to the bolt 1; And a tensile force transmitting barrel (6) installed toward the front plate (4) from the inner plate (5) through the barrel mounting hole (7). The tensile force transmitting device (50) A tensile force transmitting device manufacturing step of manufacturing a tensile force transmitting device; A tensile test specimen preparation step of fabricating a tensile test specimen 20 for tensile strength test by directly fixing the tensile force transmission device 50 therein; And a tensile strength test of the tensile test piece (20) by using a universal testing machine (15) to evaluate the direct tensile bond strength test of the filler between the precast concrete members do.
