Upper joint of stay bar of aluminum alloy suspended dome structure and ultimate bearing capacity calculation method of upper joint
The invention provides an aluminum alloy suspended dome structure supporting rod upper node and an ultimate bearing capacity calculation method thereof.The aluminum alloy suspended dome structure supporting rod upper node comprises an upper cover plate, a center cylinder, stiffening ribs, aluminum alloy H-shaped rod pieces, a lower cover plate, supporting rods, inhaul cable pin shafts and oblique inhaul cables, and the center cylinder is fixedly arranged between the upper cover plate and the lower cover plate; web plates of the aluminum alloy H-shaped rod pieces are connected to the central cylinder through bolts; upper and lower flange plates of the aluminum alloy H-shaped rod pieces are respectively connected with the upper cover plate and the lower cover plate through bolts; the multiple aluminum alloy H-shaped rod pieces are distributed from the center axis of the upper cover plate and the center axis of the lower cover plate at equal angles, the stiffening ribs are arranged in the space between every two adjacent aluminum alloy H-shaped rod pieces, and the two ends of each stiffening rib are fixed to the upper cover plate and the lower cover plate respectively. An inclined inhaul cable lug plate is fixedly arranged at the bottom of the lower cover plate, the inclined inhaul cable is connected with the inclined inhaul cable lug plate through an inhaul cable pin shaft, and the supporting rod is rotatably connected with the lower cover plate. The upper joint of the supporting rod is clear in stress, reliable in connection, good in corrosion resistance and capable of being widely applied to the field of building structures.
本发明提供一种铝合金弦支穹顶结构撑杆上节点及其极限承载力计算方法，包括：上盖板、中心圆筒、加劲肋、铝合金H型杆件、下盖板、撑杆、拉索销轴和斜向拉索，上盖板和下盖板之间固定设置有中心圆筒，铝合金H型杆件的腹板螺栓连接在中心圆筒上，铝合金H型杆件的上下翼缘板分别与上盖板和下盖板螺栓连接；多个铝合金H型杆件自上盖板和下盖板的中心轴等角度分布，加劲肋设置在相邻两个铝合金H型杆件的空间内，两端分别与上盖板和下盖板固定；下盖板底部固定设置有斜向拉索耳板，斜向拉索通过拉索销轴与斜向拉索耳板连接，撑杆与下盖板可转动连接。本申请的撑杆上节点受力明确、连接可靠，具有良好的耐腐蚀性能，可广泛使用于建筑结构领域。
