Abstract

콘크리트 벽면에 PC판넬 등을 부착 고정함에 있어서, 종래 단순한 마찰력의 작용만을 발휘하도록 한 앵커볼트를 횡으로 나사가 형성되고 확장볼트(7)의 원추상 머리부(7a)보다 직경이 작게 한 다수개로 분할가능한 횡나사원통체(1)의 내부에 끼워질 수 있는 직경의 다수의 횡방향 분할선(6)이 기단부(5)에 형성된 내부원통체(4)로 구성되는 것, 선단부와 기단부 양쪽에 각각 다수의 황방향 분할선(13a, 13b)이 형성되고 확장볼트(7)의 원추상머리부(7a) 직경보다 작고, 테이퍼형상 기단부가 있는 테이퍼면 원통체(16)가 있는 것을 개발하여 강한 결합력을 발휘하고 생산성, 작업성을 개선함.In attaching and fixing a PC panel or the like to a concrete wall, a plurality of anchor bolts are formed laterally with screws to exhibit only a simple frictional force and smaller in diameter than the conical head portion 7a of the expansion bolt 7. Consisting of an inner cylindrical body 4 formed in the proximal end 5 having a plurality of transverse dividing lines 6 of a diameter that can be fitted inside the dividable transverse threaded cylindrical body 1, respectively at both the distal end and the proximal end. A strong coupling force was developed by the formation of a tapered cylindrical body 16 having a plurality of yellow dividing lines 13a and 13b and having a diameter smaller than the conical head portion 7a of the expansion bolt 7 and having a tapered base end. Performance and productivity.
