Novel unfoldable annular tensioning integral structure
The invention provides a novel unfoldable annular tensioning integral structure. The structure comprises 2p (p is larger than 3) horizontal rods, 2p stabilizing rods, 4p stay cables, p vertical cables, p I-class joints, p II-class joints and 2p III-class joints, wherein each I-class joint is connected with the two corresponding adjacent horizontal rods, each II-class joint is connected with the two corresponding horizontal rods, the two corresponding stabilizing rods and the four corresponding stay cables, each III-class joint is connected with the corresponding stabilizing rod, the two corresponding stay cables and the corresponding vertical cable, the 2p equal-length horizontal rods are connected end to end through the I-class joints and the II-class joints to form a regular p-polygon with a radius of R to serve as an inner ring of the unfolded annular tensioning integral structure, each II-class joint of the regular polygon is connected with the two corresponding stabilizing rods with a length of h and an included angle of 2 alpha, and a corresponding plane where the corresponding stabilizing rods on each II-class joint are located is a corresponding normal plane where a circumscribed circle of the regular polygon passes through the joint. According to the structure, defects of an existing unfoldable annular tensioning integral structure form are overcome, and an unfoldableannular tensioning integral structure system which can balance annular pressure and is high in storage ratio is provided.
本发明提供一种新型可展环形张拉整体结构，包括2p(p>3)个水平杆、2p个稳定杆、4p个斜索、p个竖索、p个Ⅰ类节点、p个Ⅱ类节点和2p个Ⅲ类节点；其中，Ⅰ类节点连接相邻的2个水平杆；Ⅱ类节点连接2个水平杆、2个稳定杆和4个斜索；Ⅲ类节点连接1个稳定杆、2个斜索和1个竖索；展开态的环形张拉整体结构由2p个等长的水平杆通过Ⅰ类节点和Ⅱ类节点首尾相接连成半径为R的正p边形作为内环，在正多边形的每个Ⅱ类节点上连接有2个长度为h、夹角为2α的稳定杆；每个Ⅱ类节点上的稳定杆所在平面为正多边形外接圆过此节点的法平面。本发明弥补了现有可展环形张拉整体结构形式上的不足，提供了一种可平衡环向压力、高收纳比的可展环形张拉整体结构体系。
