Cable support joint for improving collapse resistance of space steel structure
The invention discloses a cable support joint for improving the anti-collapse performance of a space steel structure. Comprising an outer pipe, a supporting pipe inserted into the outer pipe and in lap joint with the outer pipe, a rolling shaft connected with the end of the outer pipe, an inhaul cable penetrating through the rolling shaft, a hoop arranged on the outer side of the outer pipe in a sleeving mode, a first annular push plate arranged on the outer side of the outer pipe in a sleeving mode, a second annular push plate arranged on the outer side of the supporting pipe in a sleeving mode and a spring arranged between the first annular push plate and the second annular push plate. Outer pipe notches are formed in the two sides of the outer pipe, supporting pipe lug plates are arranged on the two sides of the supporting pipe, and clamping hoop lug plates are arranged on the two sides of the clamping hoop. The supporting pipe lug plate is inserted into the outer pipe notch to achieve lap joint of the outer pipe and the supporting pipe, the supporting pipe lug plate is connected with the clamping hoop lug plate through a bolt, and the relative sliding direction of the supporting pipe lug plate and the clamping hoop lug plate is arranged in the axial direction of the outer pipe. According to the method, the energy dissipation capacity of the structure can be improved while the increase rate of the internal force of the inhaul cable is effectively controlled and the fracture probability of the inhaul cable is reduced, and the purpose of enhancing the anti-collapse performance of the space steel structure is achieved.
本发明公开了一种提高空间钢结构抗倒塌性能的索撑节点，包括外管、插入外管中并与之搭接的撑管、与外管端部相连的滚轴、穿过滚轴的拉索、套装在外管外侧的卡箍、套设在外管外侧的第一环形推板、套设在撑管外侧的第二环形推板、设置于第一环形推板和第二环形推板之间的弹簧；外管的两侧设有外管槽口，撑管的两侧设有撑管耳板，卡箍的两侧设有卡箍耳板；撑管耳板插入外管槽口中，实现外管与撑管的搭接，撑管耳板与卡箍耳板通过螺栓连接，且撑管耳板与卡箍耳板的相对滑动方向沿外管轴向设置。本发明能在有效控制拉索内力增大速率，降低拉索断裂概率的同时，还能提升结构的耗能能力，达到增强空间钢结构抗倒塌性能的目的。
