Construction method of special-shaped large-section prestressed annular frame beam
The invention relates to a construction method of a special-shaped large-section prestressed annular frame beam. The construction method comprises the following steps: step 1, selecting or blending high-performance concrete; 2, dividing construction sections; 4, ring beam steel bars are bound, corrugated pipes penetrate into the ring beam steel bars, corrugated pipes are fixed, seam needle bar anchoring holes are reserved in the position of a post-cast strip, temperature monitoring points, pressure rings for tension control and strain gauges are arranged after the steel bars are bound, and the temperature monitoring points are arranged along the axis of a ring beam; 5, concrete is poured in a layered mode; 6, the formwork is removed; 7, prestress tensioning is conducted; 8, segmented tensioning is completed; step 9, pouring a post-cast strip; and step 10, checking and accepting the whole ring beam. It is guaranteed that the formwork has enough strength and does not deform; and meanwhile, the concrete pouring forming quality and the construction progress are also ensured.
本发明涉及一种异形大截面预应力环形框架梁的建造方法，步骤1：挑选或调配高性能混凝土；步骤2：划分施工段；步骤3：模板搭设：步骤4：环梁钢筋绑扎，穿入并固定波纹管，后浇带处预留缝针筋锚固洞口，钢筋绑扎完成后布置温度监测点及张拉控制的压力环及应变片，温度监测点沿环梁轴线布置；步骤5：混凝土分层浇筑；步骤6：模板拆除；步骤7：预应力张拉；步骤8：完成分段张拉；步骤9：后浇带浇筑；步骤10：环梁整体验收。本发明保证了模板具有足够的强度，不变形；同时也保证了混凝土浇筑成型质量以及施工进度。
