Tensioning construction method for beam top tooth blocks of large-span bonded prestressed concrete beam
The invention discloses a tensioning construction method for beam top tooth blocks of a large-span bonded prestressed concrete beam. The tensioning construction method specifically comprises the following steps that 1, a formwork is laid, and beam steel bars are bound; 2, prestressed tendons are positioned; 3, a corrugated pipe is laid; 4, the size of a beam top tooth block is calculated, and steel bars of the beam top tooth block are bound; 5, the prestressed tendons are pulled; 6, an anchor bearing plate at the tensioning end of the corrugated pipe is installed; 7, a beam top tooth block formwork is installed; 8, hidden acceptance inspection is carried out; 9, concrete pouring, maintenance and form removal are carried out; 10, the prestressed tendons are tensioned; 11, hole channel grouting is conducted; and 12, anchor sealing is conducted at the tensioning end. According to the tensioning construction method for the beam top tooth blocks of the large-span bonded prestressed concrete beam, longitudinal stressed steel bars of a prestressed beam structure are not damaged, potential safety hazards are avoided, the section size of a prestressed beam is not changed, the original design appearance effect is guaranteed, the process is simple, construction is convenient, and the quality is guaranteed.
本发明公开了一种大跨度有粘结预应力混凝土梁梁顶齿块张拉施工方法，具体包括以下步骤：步骤1：铺设模板、绑扎梁钢筋；步骤2：预应力筋定位；步骤3：铺放波纹管；步骤4：梁顶齿块尺寸计算及梁顶齿块钢筋绑扎；步骤5：预应力筋穿束；步骤6：波纹管张拉端锚垫板的安装；步骤7：梁顶齿块模板安装；步骤8：隐蔽验收；步骤9：混凝土浇筑、养护、拆模；步骤10：预应力筋张拉；步骤11：孔道灌浆；步骤12：张拉端封锚。本发明不损害预应力梁结构纵向受力钢筋，无安全隐患，也不改变预应力梁的截面尺寸，保证了原设计外观效果，工艺简单，施工方便，质量有保障。
