Truss and steel beam connection cross-shaped davit structure
The invention relates to a truss and steel beam connection cross-shaped davit structure which comprises a davit body and a reinforcing part arranged on the upper portion of the davit body, the lower portion of the davit body is fixedly connected with a steel beam at the lower end of a truss, and the upper portion of the davit body is fixedly connected with a lower chord of the truss. The two variable-cross-section auxiliary plates are symmetrically welded to the centers of the two sides of the variable-cross-section main plate and form a cross-shaped structure with the variable-cross-section main plate, the variable-cross-section auxiliary plates are hinged to the corresponding steel beams through bolts respectively, the reinforcing part comprises a plurality of stiffening plates and hoops, the stiffening plates are fixedly connected to the upper portions of the right-angle inner walls of the variable-cross-section main plate and the variable-cross-section auxiliary plates, and the hoops are fixedly connected to the upper portions of the right-angle inner walls of the variable-cross-section main plate. And the hoop sleeves the upper parts of the variable cross-section main plate and the variable cross-section auxiliary plate and is welded and fixed with the stiffening plate. The device is simple in structure, convenient to operate, low in cost and capable of effectively shortening the steel truss lower-end steel beam hoisting time and shortening the construction period.
本发明是一种桁架与钢梁连接十字吊柱结构，包括吊柱主体以及设置在吊柱主体上部的加强部，吊柱主体下部与桁架下端的钢梁连接固定，上部与桁架的下弦杆连接固定，吊柱主体包括一块变截面主板和两块变截面副板，且两块变截面副板对称焊接在变截面主板的两侧中心，并与变截面主板组成十字形结构，变截面副板分别与对应的钢梁通过螺栓铰接连接，加强部包括若干加劲板和环箍，若干加劲板固定连接在变截面主板和变截面副板的直角内壁上部，且环箍套设在变截面主板和变截面副板的上部并与加劲板焊接固定。本发明结构简单，操作便捷，成本低廉，同时可有效缩短钢桁架下端钢梁吊装时间，节省工期。
