Double-limb pier cross tie beam construction method
The invention relates to a double-limb pier cross tie beam construction method which comprises the steps that when a double-limb pier is constructed, a reserved notch matched with a cross tie beam is formed in the double-limb pier, and when double-limb pier column steel bars are installed at the reserved notch, the cross tie beam steel bars are pre-buried into a pier column and comprise pre-buried steel bars and bent steel bars; the length of the pre-embedded steel bar is equal to the length of the portion, penetrating into the pier column, of the horizontal bar of the cross tie beam, the length of the bent steel bar is larger than that of the pre-embedded steel bar, the pre-bent section of the bent steel bar is placed in the reserved notch, and after the pier column at the reserved notch is formed in a pouring mode and the pier column formwork ascends, the bent steel bar is straightened and extends out of the reserved notch. By arranging the reserved notches, the pier column formwork can directly climb upwards, the construction period is shortened, cost is saved, potential safety hazards are reduced, after the formwork climbs, the bent steel bars are straightened, connectors of the bent steel bars extend out of the reserved notches, the situation that connectors of main reinforcements of a cross tie beam are concentrated in the same area is avoided, the project quality is ensured, and the construction method is simple in step, convenient to operate and high in practicability. The effect is good.
本发明关于一种双肢墩横系梁施工工法，施工双肢墩时在其上设置与横系梁匹配的预留槽口，预留槽口处安装双肢墩墩柱钢筋时，将横系梁钢筋预埋至墩柱内，其中包括预埋钢筋和折弯钢筋，预埋钢筋的长度等于横系梁水平筋深入墩柱内的长度，折弯钢筋的长度大于预埋钢筋的长度，折弯钢筋的预弯段放置于预留槽口内，待预留槽口处墩柱浇筑成型、墩柱模板上升后，将折弯钢筋调直，折弯钢筋伸出预留槽口。本发明通过设置预留槽口，使墩柱模板可直接向上爬升，缩短工期，节约成本，降低安全隐患，模板爬升后，折弯钢筋调直，使得折弯钢筋的接头伸出预留槽口，避免横系梁主筋接头在同一区域集中，确保工程质量，该施工工法步骤简单，操作方便，效果良好。
