Construction method for bracket floor steel beam of large cantilever steel structure
The invention provides a construction method for a large-cantilever curved-surface connecting bracket steel beam, which comprises the following steps of: forming a first supporting groove and a second supporting groove in an arc-shaped supporting plate, and limiting the lateral positions of a transverse bracket and an inclined bracket through a bracket position adjusting bolt; a column bottom sand box is arranged at the bottom end of the formwork supporting column. The transverse position of the side formwork between the legs is controlled through a formwork supporting pier on the cantilever supporting plate and a sixth position adjusting body; transverse inner supports and vertical inner supports which are perpendicular to each other are arranged in the net rack segments; the spatial position of the net rack segment is adjusted by adjusting the lengths of the first suspender, the second suspender and the third suspender; the position of the sliding cross beam is limited through the transverse position adjusting bolt, and then the lateral positions of the splicing supporting column and the net rack guide groove are controlled through the eighth position adjusting body and the ninth position adjusting body. According to the method, the mounting and positioning precision of the transverse bracket and the inclined bracket is improved, the column side concrete pouring difficulty is reduced, and the hoisting and mounting quality of the net rack section is improved.
本发明提供一种大悬挑曲面连接牛腿钢梁施工方法，在弧形撑板上设置第一撑槽和第二撑槽，并可通过牛腿调位栓限定横向牛腿和斜向牛腿的侧向位置；在模板撑柱的底端设置了柱底砂箱；通过悬臂撑板上的模板撑墩及第六调位体控制腿间侧模的横向位置；在网架节段内设置相互垂直的横向内撑和竖向内撑；通过调整第一吊杆、第二吊杆和第三吊杆的长度，调整网架节段的空间位置；先通过横向调位栓限定滑移横梁的位置，再通过第八调位体和第九调位体控制拼装撑柱及网架导槽的侧向位置。本发明提升了横向牛腿和斜向牛腿的安装定位精度，减小了柱侧混凝土浇筑难度，提高了网架节段吊放安装的质量。
