Large-opening multi-stage bifurcated cable-supported aluminum alloy reticulated shell structure system and construction method
A large-opening multi-stage bifurcated cable-supported aluminum alloy reticulated shell structure system comprises a reticulated shell which comprises a circular ring body structure defined by a first steel ring beam and a second steel ring beam and cantilever structures defined by the second steel ring beam and a steel arched beam, and an opening is formed between the cantilever structures and located at the position of the second steel ring beam; the first inner ring cable is circumferentially arranged on the lower side of the reticulated shell, is pulled with the first steel ring beam through a first radial cable, and is connected with the second steel ring beam through a first steel stay tube; the second inner ring cable is arranged on the lower side of the steel arched beam in an arc shape, is arranged with the second steel ring beam in a pulling mode through a second radial cable and is connected with the aluminum structure single-layer reticulated shell at the cantilever structure through a second steel supporting pipe; and the sliding basin type support is arranged on the outer edge of the reticulated shell. The cable has the advantages of being light in structure, reasonable in stress and free of thrust self-bearing, and the advantages of being light in weight, high in strength, resistant to corrosion, integrated, excellent in waterproof performance, good in building appearance, high in inhaul cable strength, good in permeability and the like of an aluminum alloy structure are brought into full play.
一种大开口多级分叉索承铝合金网壳结构体系，包括：网壳，包括由第一钢环梁和第二钢环梁围闭形成的圆环体结构，由第二钢环梁与钢拱梁围闭形成的悬挑结构，并在悬挑结构之间且介于第二钢环梁处形成开口；第一内环索，呈圆周状设置在网壳的下侧，并通过第一径向索与第一钢环梁拉设，通过第一钢撑管与第二钢环梁连接；第二内环索，呈弧形设置在钢拱梁下侧，并通过第二径向索与第二钢环梁拉设，通过第二钢撑管与悬挑结构处的铝结构单层网壳连接；滑动盆式支座，设置在网壳外边沿。本发明具有结构轻盈、受力合理、无推力自承重的优点，充分发挥了铝合金结构轻质高强、耐腐蚀、一体化、防水性能优越、建筑外观佳以及拉索强度高、通透性好等优点。
