Large-cantilever prestressed bent cap cast-in-place bracket
The invention relates to the technical field of constructional engineering, and in particular relates to a large-cantilever prestressed bent cap cast-in-place bracket. The problems that due to fact that a bent cap cantilever is long, the total weight is large, super-high-altitude operation is adopted, the influence of wind power is large, the bearing capacity of the bracket cannot be guaranteed, and potential safety hazards exist are solved. The bracket is characterized by comprising triangular brackets arranged on two opposite side walls of a pier stud, wherein each triangular bracket comprises a vertical rod, a transverse rod and an inclined supporting rod. The bottom of each vertical rod is fixedly connected with a supporting piece. Each supporting piece is connected with an embedded part through a bolt or a flange, the embedded part comprises a plurality of embedded steel bars arranged in the pier column, corrugated pipes are arranged on the opposite sides of the embedded steel bars, lap joint ribs are arranged in the corrugated pipes in a penetrating mode, the corrugated pipes and the embedded steel bars are arranged in parallel, and reinforcing ribs are arranged on the outersides of the corrugated pipes and the embedded steel bars in a sleeving mode. Compared with an existing bracket structure, the bracket has the advantages that the overall rigidity, stability and safety are improved.
本申请涉及建筑工程技术领域，具体涉及一种大悬臂预应力盖梁现浇托架，旨在解决由于盖梁悬臂长，总体重量大，加之超高空作业，受风力影响较大，托架承重能力不能保证，具有安全隐患的问题，其技术要点在于包括设置在墩柱相对两侧壁上的三角托架，所述三角托架包括竖杆、横杆和斜撑杆，所述竖杆的底部固定连接有支撑件，所述支撑件通过螺栓或法兰连接有预埋件，所述预埋件包括若干根设置于所述墩柱内部的预埋钢筋，所述预埋钢筋相对一侧设有波纹管，所述波纹管内穿设有搭接筋，所述波纹管与预埋钢筋平行设置且两者外侧套设有加强筋。本发明比现有托架结构整体刚度、稳定性和安全性均有提高。
