发明名称 FASTENING STRUCTURE OF NATIVE ROCK AND THE METHOD
摘要 A combining structure of natural stones, and its combining method are provided to prevent the separation of natural stones due to the external impact, thereby minimizing the human casualties or injuries due to the falling of natural stone. A combining structure of natural stones combines first and second natural stones where first and second combination holes are formed, respectively, by using a combining unit(100), wherein the combining unit comprises a first sleeve(110) which is inserted into the first combination hole of the first natural stone, and has a penetration hole at the center and a first cut part(112) at the front part; a first bolt member(120) which is inserted into the penetration hole of the first sleeve and is provided with a first expansion part(122) for expanding the first cut part in case of backward going; a second sleeve(130) which has a penetration hole at the center and a second cut part(132) at the front part; a second bolt member(140) which is inserted into the penetration hole of the second sleeve and is provided with a second expansion part(142) for expanding the second cut part in case of backward going; and a nut member whose one terminal part is combined to the back terminal part of the first bolt member and whose other terminal part is combined to the back terminal part of the second bolt member.
