Combined large-span orthogonal truss roof structure supported by four corners of double-arch three-dimensional truss on ground, forming method and application
The invention discloses a combined large-span orthogonal truss roof structure supported by four corners of a double-arch three-dimensional truss on the ground. The combined large-span orthogonal truss roof structure comprises the double-arch three-dimensional truss on the ground, an orthogonal plane arc-shaped truss, roof connecting steel beams, large-opening boundary arc-shaped arched beams, two-side single-layer latticed shells and small-opening boundary structures. The double-arch three-dimensional truss on the ground is composed of two inclined vertical face arc-shaped inverted triangular three-dimensional arch trusses. The orthogonal plane arc-shaped truss is composed of multiple orthogonal plane arc-shaped trusses. The roof connecting steel beams comprise the upper chord steel beams and the lower chord steel beams. The large-opening boundary arc-shaped arched beams are composed of two inclined vertical face arc-shaped arched beams. The two-side single-layer latticed shells comprise radial main inclined rods and annular auxiliary rods. The small-opening boundary structures comprise main arc-shaped arches on the ground, longitudinal connecting rods and inclined connecting rods. Based on an overall stress system formed by combining the double-arch three-dimensional truss on the ground and the orthogonal plane arc-shaped truss, component forming modules are clear, force transmission is clear, and the combined large-span orthogonal truss roof structure has the advantages of being large in two-way span space, provided with arc-shaped curved faces and high in bearing capacity.
本发明公开了一种双拱立体桁架四角落地支承的组合大跨度正交桁架屋盖结构，包括落地双拱立体桁架、正交平面弧形桁架、屋盖连接钢梁、大开口边界弧形拱梁、两侧单层网壳和小开口边界结构；所述落地双拱立体桁架由2榀斜立面弧形倒三角立体拱桁架组成；所述正交平面弧形桁架由多榀正交向平面弧形桁架组成；所述屋盖连接钢梁包括上弦钢梁和下弦钢梁；所述大开口边界弧形拱梁由2榀斜立面弧形拱梁组成；所述两侧单层网壳包括径向主斜杆、环向次杆；所述小开口边界结构包括落地弧形主拱、纵连接杆和斜连接杆。本发明基于落地双拱立体桁架和正交平面弧形桁架结合的整体受力体系，构件组成模块明确，传力清晰，具有双向大跨空间、弧形曲面和高承载特点。
