Anti-twisting structure for ceiling light steel keels

XU JIANFENG / LI SHAOFENG

The invention discloses an anti-twisting structure for ceiling light steel keels. The structure comprises a main keel, a secondary keel and a connecting fastener, wherein the main keel and the secondary keel are clamped by the connecting fastener to form a cross-shaped fixed structure; the main keel and the secondary keel are of the same structure, and each of the main keel and the secondary keelcomprises a bottom plate, two side plates formed by vertical bending of two sides of the bottom plate in the same direction and two fastener plates formed by opposite bending of the tail ends of the two side plates; the connecting fastener comprises a fastener top plate, two fastener side plates formed by vertical bending of two sides of the fastener top plate in the same direction and fixing clamping grooves arranged at the tail ends of the two fastener side plates; the fastener top plate and the two fastener side plates form a U-shaped bayonet with a downward opening; and the U-shaped bayonet of the connecting fastener is buckled on the outer side of the main keel from top to bottom, and the two fastener plates of the secondary keel are inserted into the fixing clamping grooves. The structure can not only be constructed effectively and quickly, but also prevents distortion, deformation and falling-off of the connecting fastener of the main keel and the secondary keel due to irregularclimbing and trampling.

本发明公开了吊顶轻钢龙骨防扭曲结构，包括主龙骨、次龙骨和连接扣件，连接扣件将主龙骨与次龙骨卡住构成十字状的固定结构；主龙骨和次龙骨的结构相同，包括底板、底板的两侧相同方向垂直折弯形成的两个侧板以及两个侧板的末端相向地折弯形成的两个卡扣板；连接扣件包括扣件顶板、扣件顶板的两侧相同方向垂直折弯形成的两个扣件侧板、两个扣件侧板的末端开设有固定卡槽；所述扣件顶板和两个扣件侧板形成开口向下的U型卡口；连接扣件的U型卡口从上往下扣设在主龙骨的外侧，次龙骨的两个卡扣板穿插于固定卡槽中。该结构既能有效快捷的进行施工，又避免了不规范攀爬、踩踏造成主龙骨同次龙骨的连接扣件扭曲、变形、脱落。
