Pre-tensioning method prestressed steel reinforced concrete combined bracket bearing structure
The invention relates to the field of tensioning pedestal bracket equipment, in particular to a pre-tensioning method prestressed steel reinforced concrete combined bracket bearing structure. The problems that concrete of a traditional tensioning pedestal is crushed, concrete at the tension position is cracked, and only one beam can be tensioned between two tensioning brackets are solved. The steel reinforced concrete combined bracket is fixed to the tensioning pedestal and comprises a steel box formed by welding profile steel, a plurality of pieces of I-shaped steel welded to one side of the steel box and a steel bar set fixed to the steel box. The steel box, the I-shaped steel and the steel bars are wrapped through concrete pouring. According to the device, the pressure-bearing area bracket wraps the profile steel and the steel bar set through the concrete, the compressive strength of the concrete and the structural integrity are improved, meanwhile, multiple beams can be tensioned synchronously, and the tensioning efficiency is improved.
本发明涉及张拉台座牛腿设备领域，具体为一种先张法预应力型钢混凝土组合牛腿承重结构。解决了传统张拉台座混凝土被压溃，受拉处混凝土被拉裂，两个张拉牛腿之间只能张拉一片梁的预应力等问题。型钢混凝土组合牛腿固定于张拉台座上，所述型钢混凝土组合牛腿包括由型钢焊接而成的钢箱，焊接在钢箱一侧的若干工字型钢和固定在钢箱上的钢筋组；钢箱、工字型钢和钢筋通过混凝土浇筑包裹。本装置将承压区牛腿利用混凝土包裹型钢和钢筋组，提高混凝土的抗压强度和提高了结构的整体性，同时可多片梁同步张拉，提高张拉效率。
