Double-triangle combined floor supporting three-dimensional arch truss large-span roof and forming method
The invention relates to a double-triangle combined floor supporting three-dimensional arch truss large-span roof and a forming method, a floor three-dimensional arch truss combination comprises two groups of triangular floor three-dimensional arch trusses, and the two groups of triangular floor three-dimensional arch trusses are in central symmetry along a central positioning point, intersect and are rigidly connected to form a hexagonal star structure; a hexagonal space is formed in the floor three-dimensional arch truss combination, and outer boundary single-layer latticed shells are arranged in six corners of the outer side of the hexagonal space. The roof structure has the beneficial effects that lateral supporting of the annular plane arc truss combination is achieved through the roof radial connecting steel beams, an overall stress mode is formed through the outer boundary single-layer latticed shell and the center single-layer latticed shell, the self weight can be reduced, and the bearing performance can be guaranteed; the building modeling and functions of the multi-angle combined floor supporting large-span roof with a bottom multi-direction large-span space, a roof multi-direction arc-shaped curved surface, high bearing rigidity and an entrance boundary structure are achieved.
本发明涉及一种双三角组合落地支承立体拱桁架大跨屋盖及构成方法，落地立体拱桁架组合包括两组三角落地立体拱桁架，两组三角落地立体拱桁架沿中心定位点中心对称，交汇并刚性连接形成六角星结构，落地立体拱桁架组合内部形成六边形空间，六边形空间外侧的六个角内均设有外边界单层网壳。本发明的有益效果是：通过屋盖径向连接钢梁实现环向平面弧形桁架组合的侧向支撑，通过外边界单层网壳、中心单层网壳构成整体受力模式，可达到在减轻自重和保证承载性能的同时，实现底部多向大跨空间、屋面多向弧形曲面、高承载刚度和入口边界结构的多角组合落地支承大跨度屋盖建筑造型及功能。
