Prefabricated bent cap sectional wet connection counter-pulling construction method
The invention discloses a prefabricated bent cap sectional wet connection counter-pulling construction method, and relates to the technical field of construction. The method comprises the specific steps that a, finish rolling deformed steel bars are pre-buried in a bearing platform; b, upper cover beam sections are installed at the upper ends of the bridge piers correspondingly, and hole channels are formed in the ends, close to the other cover beam section, of the cover beam sections; c, the finish-rolled deformed steel bars penetrate through the hole channels and are connected with the finish-rolled deformed steel bars pre-buried in the bearing platform, and the finish-rolled deformed steel bars penetrating through the hole channels are in threaded connection with counter-pull nuts; d, steel bars are exposed at the ends, close to the other bent cap section, of the bent cap sections, and the steel bars are connected with the steel bars of the other bent cap section; e, concrete is poured between the bent cap sections; and f, the prestressed tendons penetrate through the bent cap sections and are tensioned; and the finish-rolled deformed steel bars are in a vertical state. The construction method has the beneficial effects that the stability of the bent cap sections is guaranteed through the tension of the finish rolling deformed steel bars, a support does not need to be arranged, and the construction speed is greatly increased.
本发明公开了一种预制盖梁分节湿接反拉施工方法，涉及施工技术领域；具体步骤为：步骤a：在承台上预埋精轧螺纹钢；步骤b:在桥墩上端分别安装上盖梁节段，在盖梁节段靠近另一个盖梁节段的一端均设有孔道；步骤c：在孔道中穿过精轧螺纹钢并和预埋在承台上的精轧螺纹钢连接，穿过孔道的精轧螺纹钢上螺纹连接有反拉螺母；步骤d：盖梁节段靠近另一个盖梁节段的一端均裸露有钢筋，将钢筋和另一个盖梁节段的钢筋连接起来；步骤e：在盖梁节段之间浇筑混凝土；步骤f：预应力筋穿过盖梁节段，并张拉；所述精轧螺纹钢呈竖直状态。本发明的有益效果是：用精轧螺纹钢的拉力来保证盖梁节段的稳定性，不需要设置支架，大大提升了施工的速度。
