Construction method applying pulling and tying method in large-span net rack starting frame
The embodiment of the invention provides a construction method applying a pulling and tying method in a large-span net rack starting frame. The construction method comprises the steps that spherical net rack supporting seats on the two sides are assembled; an A-section starting span arc-shaped net rack and a B-section starting span arc-shaped net rack are assembled; The A-section starting span arc-shaped net rack and the B-section starting span arc-shaped net rack are spliced; and the A-section starting span arc-shaped net rack and the B-section starting span arc-shaped net rack are in air butt joint. By applying the scheme provided by the embodiment of the construction method, the construction efficiency can be improved; in addition, the spherical net rack supporting seats are applied to realize the effect that the free end can freely rotate by taking the spherical net rack supporting seats as fulcrums in the hoisting process so that the hoisting position of the starting span arc-shaped net racks can be conveniently adjusted; and moreover, the starting span arc-shaped net racks are pulled tied by adopting steel strands, steel strand lock catches and chain blocks, and therefore the deflection of the starting span arc-shaped net racks can be provided, and the hoisting safety is improved.
本发明实施例提供了一种大跨度网架起步架中应用拉结法的施工方法，包括：两侧球形网架支座的拼装；A段起步跨弧形网架和B段起步跨弧形网架的拼装；A段起步跨弧形网架和B段起步跨弧形网架的拼装；A段起步跨弧形网架和B段起步跨弧形网架的空中对接。应用本发明实施例提供的方案，通能够提高施工效率；此外，应用球形网架支座实现在吊装过程中自由端能够以球形网架支座为支点自由转动方便调整起步跨弧形网架的吊装位置；并且，采用钢绞线、钢绞线锁扣以及倒链对起步跨弧形网架进行拉结，能够提供起步跨弧形网架的挠度，提高吊装安全性。
