Large-span concrete beam retard-bonded prestressed construction method
The invention discloses a large-span concrete beam retard-bonded prestressed construction method, and relates to the technical field of constructional engineering. The large-span concrete beam retard-bonded prestressed construction method aims to solve the problem that the large-span prestressed construction cost is greatly improved due to the fact that required prestressed tendons are mostly purchased directly during existing large-span prestressed construction. The method comprises the steps of 1, burying prestressed steel strands; 2, checking a component; step 3, manufacturing prestressed tendons; step 4, penetrating prestressed tendons; step 5, inspecting an anchorage device; step 6, installing the anchorage device, and pre-detecting tensioning equipment; step 7, tensioning; step 8, duct grouting; and step 9, plugging an anchor head.
本发明公开了一种大跨度混凝土梁缓粘结预应力施工方法，涉及建筑工程技术领域，为解决现有的大跨度预应力施工时大多是直接购买获得需要的预应力筋，导致大跨度预应力施工成本大大提高的问题。步骤1：埋设预应力钢绞线；步骤2：检查构件；步骤3：预应力筋制作；步骤4：穿预应力筋；步骤5：锚具检验；步骤6：安装锚具及张拉设备预检；步骤7：张拉；步骤8：孔道灌浆；步骤9：锚头封堵。
