Cable-beam composite large-span cable support arch shell and construction method thereof
The invention relates to the technical field of structures covering large-area spaces, and discloses a cable-beam composite large-span cable support arch shell and a construction method thereof. Comprising outer ring beams which are arranged along the periphery of an arch shell and define a ring, arch shell beams which are arranged in the range of the outer ring beams in parallel at intervals, and joist cables which are perpendicular to the arch shell beams and are arranged in the range of the arch shell beams at intervals. The arch shell beams and the joist cables enclose grids which are fully distributed in the range of the outer ring beams, and the ends of the arch shell beams and the ends of the joist cables are hinged to the outer ring beams; the beam supporting cable penetrates through and supports the arch shell beam and is connected with the arch shell beam through the cable clamp. In the invention, the steel beams in one direction in the arch-shaped steel beam grid are replaced by the inverted-arch-shaped beam supporting cables with prestress, and the beam supporting cables support the arch shell beam in a form of penetrating through the arch shell beam, so that the arch shell beam is prevented from warping down or losing stability due to overlarge span; therefore, the wind resistance of the steel beam grid and the large-span cable support arch shell of the prestressed cable net are combined, and the requirement of a large-span single-span transparent ceiling can be met.
本发明涉及覆盖大面积空间的结构技术领域，公开了一种索梁复合的大跨度索托拱壳及其施工方法，包括沿拱壳一周设置并围合成环的外环梁、平行间隔设置在外环梁范围内的拱壳梁、以及垂直于拱壳梁并间隔设置在拱壳梁范围内的托梁索；拱壳梁以及托梁索围合成布满外环梁范围内的网格，拱壳梁以及托梁索的端部均与外环梁铰接连接；托梁索穿透并托住拱壳梁，并通过索夹与拱壳梁连接。本发明中，通过将拱状的钢梁网格中一个方向上的钢梁换成反拱形且带预应力的托梁索，托梁索以穿透拱壳梁的形式托住拱壳梁，避免拱壳梁因跨度过大而下挠或失稳，从而形成了兼具钢梁网格的抗风能力以及预应力索网的大跨度的索托拱壳，能够满足大跨度的单跨透明顶棚的需求。
