buckling resistant means for hanger bolt of drop ceiling system
The present invention relates to a buckling resistance means for a hanger bolt of a lightweight steel frame ceiling system having a spacer, wherein the spacer is interposed between a tubular part and a full thread bolt, a screw processing part capable of being coupled to the full thread bolt is formed on an inner circumferential surface, and a tapered part or a multi-stage cake shape part capable of being in surface contact with inner circumferential surfaces of the tubular parts having different inner diameters is formed on an outer circumferential surface.
본 발명은, 관형부와 전산볼트 사이에 스페이서를 개재시키되, 내주면에 상기 전산볼트에 체결될 수 있는 나사가공부가 형성되고, 그리고 외주면에 상이한 내경을 가진 상기 관형부들의 내주면에 면접촉할 수 있는 테이퍼부 또는 다단케익형상부가 형성된 상기 스페이서를 구비한 '경량철골천장시스템의 행거볼트용 좌굴저항수단'에 관한 것이다.
