Joint stiffened intersecting welded steel pipe
The invention discloses a joint stiffened intersecting welded steel pipe. The joint stiffened intersecting welded steel pipe comprises a main pipe, at least two branch pipes, horizontal stiffening plates and annular stiffening plates, wherein an included angle between the main pipe and each branch pipe is smaller than a set angle; the horizontal stiffening plates are fixedly arranged between the main pipe and each branch pipe or between the branch pipes; and the annular stiffening plates are fixedly arranged at the intersections of the branch pipes and the outer surface of the main pipe and inthe middle of the intersection lines of the branch pipes and the main pipe to wrap the main pipe, the branch pipes and the horizontal stiffening plates. By means of the horizontal stiffening plates,the length of welding seams for transmitting branch pipe loads to the main pipe is increased, so that the force transmission is more uniform, and the in-plane rigidity of joints is increased at the same time. The annular stiffening plates increase the radial stiffness of the main pipe and the branch pipes, improve the deformation resistance of the main pipe and the branch pipes, and improve the stable bearing capacity of the horizontal stiffening plates at the same time. According to the joint stiffened intersecting welded steel pipe, the stiffening method can effectively improve the rigidityand strength of the intersecting welded steel pipe joints, the force transmission is uniform, the stress concentration degree is reduced, and the overall bearing capacity of the joints is improved.
一种节点加劲相贯焊钢管，包括：主管、至少两根支管、水平加劲板、环形加劲板，且所述主管和支管的夹角小于设定角度；所述水平加劲板固定设置于所述主管和支管之间或各支管之间；在支管与主管外表面相交处和支管与主管相贯线的中间位置固定设置环形加劲板包裹住所述主管、支管和水平加劲板。通过水平加劲板，增加了支管荷载传递到主管的焊缝长度，使传力更加均匀，同时增加节点平面内刚度。环形加劲板增加了主管和支管的径向刚度，提高抵抗变形的能力。同时环形加劲板提高了水平加劲板的稳定承载力。本发明的加劲方法能有效提高相贯焊钢管节点的刚度和强度，传力均匀，降低应力集中程度，提高节点的整体承载能力。
