Steel bridge high-strength bolt anti-loose connection node device
The invention discloses a high-strength bolt anti-loose connecting joint device for a steel bridge and belongs to the technical field of bolt connection. The device comprises a first steel beam and a second steel beam, each of which comprises upper flanges, webs and lower flanges; an upper C-shaped steel plate which is arranged on the upper flange, a convex block which is arranged on the inner side of the upper C-shaped steel plate, a first steel plate which is arranged on the convex block, a first bolt that penetrates through the upper C-shaped steel plate, the first steel plate and the upper flange to fixedly connect these components, groove-shaped steel plates that are symmetrically arranged on the two sides of the lower flange, second bolts which penetrate through the groove-shaped steel plates and the lower flange to fixedly connect the both, belly groove-shaped steel plates which are symmetrically arranged on the two sides of the web plate, and third bolts which penetrate through the belly groove-shaped steel plates and the web plate to fixedly connect the both. The high-strength bolt connection joint is supported and fixed through the steel plate, an integral joint is formed, and therefore the looseness prevention performance of the high-strength bolt connection joint of the steel bridge is improved.
本发明公开了一种钢桥高强螺栓防松连接节点装置。属于螺栓连接技术领域,包括第一钢梁和第二钢梁，第一钢梁和第二钢梁包括上翼缘、腹板及下翼缘；设于上翼缘的上部C型钢板，设于上部C型钢板内侧的凸块及设于所述凸块上的第一钢板，第一螺栓穿过上部C型钢板、第一钢板及上翼缘将其固定连接在一起；对称设于下翼缘两侧的槽型钢板，第二螺栓穿过槽型钢板和下翼缘将其固定连接在一起；对称设于所述腹板两侧的腹部槽型钢板，第三螺栓穿过所述腹部槽型钢板和腹板将其固定连接在一起。本发明通过利用钢板对高强螺栓连接节点处进行支撑和固定，形成整体性节点，从而提高钢桥高强螺栓连接节点的防松性。
