Pentagonal sequence multi-supporting-rod mixed type cable dome structure
The invention discloses a pentagonal sequence multi-supporting-rod mixed type cable dome structure. In the prior art, the structure construction difficulty is high, and the node structure is complex. The device comprises two types of pentagonal space basic units, an inner ring cable and an outer ring beam. The spatial basic units are divided into two spatial three-dimensional pentagons, namely a forward spatial three-dimensional pentagon and an inverted spatial three-dimensional pentagon, the former spatial three-dimensional pentagon is provided with three supporting rods and two stay cables, the latter spatial three-dimensional pentagon is provided with four supporting rods and a stay cable, and the latter spatial three-dimensional pentagon is provided with four upper chord ridge cables, an upper chord annular component and a lower chord annular cable section. In the space basic units, one ends of the supporting rods and the stay cables are connected with upper chord ridge cable nodes, and the other ends intersect at the same lower chord node. The same-kind space basic units expand in the circumferential direction to form a forward-placed circumferential substructure and a reverse-placed circumferential substructure, and the lower chord ring cable sections of the same circle are connected end to end to form a lower chord ring cable. The two kinds of annular substructures alternately expand in the radial direction, the bottommost annular substructure is supported on the outer ring beam, and the top of the bottommost annular substructure is provided with an inner ring cable. The structure is stable, the building modeling is simple and attractive, and the space effect is strong.
本发明公开了五边形序列多撑杆混合型索穹顶结构。现有技术存在着结构施工难度大，节点构造复杂。本发明包括两类五边形空间基本单元、内环索、外环梁。空间基本单元分为正放和倒放两种空间立体五边形，前者有三根撑杆和两根斜索，后者有四根撑杆和一根斜索，此外两者皆有四根上弦脊索、一根上弦环向构件和一根下弦环索段。空间基本单元内，撑杆和斜索的一端接上弦脊索节点，另一端交汇于同一个下弦节点。同类空间基本单元沿环向扩展，形成正放和倒放两类环向子结构，同圈下弦环索段首尾相连构成下弦环索；两类环向子结构沿径向交替扩展，最底部环向子结构支承在外环梁上，顶部设有内环索。本发明结构稳定，建筑造型简洁、美观、空间效果强。
