Large bent cap supporting structure based on small-diameter cross-core steel bars and construction method of large bent cap supporting structure
The invention provides a large bent cap supporting structure based on a small-diameter center-penetrating steel bar and a construction method of the large bent cap supporting structure. The large bent cap supporting structure comprises a pier column, a jack, a fixing sleeve, the center-penetrating steel bar, a supporting beam arranged above the center-penetrating steel bar, a lower wing assembly, an upper wing assembly, a pre-tensioning assembly and a contact gasket, wherein the center-penetrating steel bar is arranged in the fixing sleeve in a penetrating mode, and the two ends of the center-penetrating steel bar are exposed out of the pier column to form supporting ends; the pre-tensioning assemblies are symmetrically arranged on the two sides of the center penetrating steel bar and connected between the upper wing plate and the lower wing plate so as to be used for applying pre-tensioning force between the upper wing plate and the lower wing plate. And the contact gaskets are filled among the mutual contact surfaces of the upper wing plate, the lower wing plate, the column embracing assembly and the outer wall of the pier column. The method not only solves the problem of great hidden danger of quality and safety caused by omission of anti-bending checking calculation in a conventional cross-core steel bar method process design, but also solves the problem of mutual conflict among the distance between the steel bars of the pier body, the diameter of the cross-core steel bar and the anti-bending performance of the steel bar under the condition of simultaneously considering the anti-shearing checking calculation and the anti-bending checking calculation of the cross-core steel bar.
本发明提供了一种基于小直径穿心钢棒的大型盖梁支承结构及其施工方法，包括墩柱，千斤顶，固定套管，穿设于固定套管内且两端露出墩柱形成支撑端的穿心钢棒，设置于穿心钢棒上方的支撑梁，下翼组件，上翼组件，预张紧组件，接触衬垫；所述预张紧组件对称设置于穿心钢棒两侧且连接于上翼板与下翼板之间，以用于对上翼板与下翼板之间施加预拉力；所述接触衬垫填充于上翼板、下翼板、抱柱组件与墩柱外壁的相互接触面之间。本发明不仅解决了常规穿心钢棒法工艺设计中遗漏抗弯验算造成质量安全重大隐患的问题，同时还解决了同时考虑穿心钢棒的抗剪验算和抗弯验算的情况下，墩身钢筋间距、穿心钢棒直径以及钢棒抗弯性能之间相互冲突的问题。
