The invention discloses a crane, a crane truss, a crane truss node structure and a construction method thereof.The crane truss comprises a track, the track comprises an upper chord and a lower chord which are opposite, the upper chord is provided with a box-shaped structure with a box-shaped cross section, and the box-shaped structure comprises an upper flange and a lower flange which are opposite; a middle web is arranged between the upper flange and the lower flange; a transverse partition plate is arranged on the middle web plate; an outer side web plate is arranged below the transverse partition plate, a first diagonal web member and a second diagonal web member are connected to the outer side web plate, and the transverse partition plate and the extension line of the first diagonal web member and the extension line of the second diagonal web member intersect at the node position of the upper chord. The middle web transmits the vertical load of the track to the node position through the transverse partition plate. The anti-fatigue performance of the truss can be improved so as to meet the use requirements of the crane truss, especially a large-span crane truss, the reliability of the truss during use is improved, and the service life of the truss during use is prolonged.
本发明公开了一种吊车、吊车桁架、吊车桁架节点结构及其施工方法,所述吊车桁架包括轨道,所述轨道包括相对的上弦和下弦,所述上弦设置有横截面呈箱型的箱型结构,所述箱型结构包括:相对的上翼缘、下翼缘,所述上翼缘和下翼缘之间设置有中间腹板;所述中间腹板上设置有横隔板;在所述横隔板下方设置有外侧腹板,所述外侧腹板上分别连接有第一斜腹杆和第二斜腹杆,所述横隔板与所述第一斜腹杆和第二斜腹杆的延长线相交于所述上弦的节点位置,所述中间腹板通过所述横隔板将所述轨道的竖向载荷传递至所述节点位置。本发明能够提高桁架的抗疲劳性能,以满足吊车桁架,特别是大跨度吊车桁架的使用需求,提高桁架使用时的可靠性和使用寿命。
