PURPOSE: A strong anchor bolt with a spacer is provided to prevent a nut coupled onto the upper part of a bolt from being spun with no traction by being out of a screw-thread as a spacer is arranged on the top surface of stone. CONSTITUTION: A strong anchor bolt with a spacer includes a bolt (110), a sleeve (120), a spacer (130), a washer (140), and a nut (150). The bolt penetrates through a construction hole formed on stone and includes a wedge (112) on the lower part and a screw-thread (114) on the outer periphery. The sleeve is divided so that the lower part of the sleeve is bent outwardly by the wedge while the sleeve surrounds the outer periphery of the bolt. The washer and the nut are coupled on the upper part of the bolt penetrated through the upper part of the spacer. A spacer includes the sleeve fitted into the construction hole; an adhesion plate (132) seated on the top surface of the stone; a coupling unit (134) formed on the top surface of the adhesion plate; and a screw-thread (136) on the outer periphery of the coupling unit. The sleeve, the adhesion plate, and the coupling unit are formed to be integrated. A supporting member having an anchor bolt as a base is coupled to a screw-thread formed on the coupling unit. |
