Construction method of PC outer wall connecting joint in basement civil air defense project
The invention discloses a construction method of a PC outer wall connecting joint in a basement civil air defense project, which comprises the following steps of: reserving a horizontal construction joint above a basement bottom plate, arranging a water stop steel plate at the position of the horizontal construction joint, and reserving a steel bar joint above the basement bottom plate; according to the steel bar positioning line of the PC outer wall, positioning ribs for fixing the PC outer wall are initially determined; the PC outer wall is hoisted to a basement bottom plate, and after the appearance of the PC outer wall and the hanging ring connection condition are detected, the PC outer wall slowly descends to the position above the basement bottom plate through sliding ropes and agraffes; installing an inclined support for the PC outer wall, and correcting the perpendicularity of the PC outer wall; expansion water-stop strips are arranged on the two sides of the bottom of the PC outer wall, and the outer sides of the expansion water-stop strips are sealed through non-shrinkage mortar. Whether a grouting sleeve of the PC outer wall is blocked or not is checked, and grouting operation is conducted on the PC outer wall; and waterproof paint is smeared on the outer side of the joint of the PC outer wall and the basement bottom plate, and waterproof coiled materials are laid on the outer side of the waterproof paint.
本发明公开了一种地下室人防工程中PC外墙连接节点的施工方法，其包括：在地下室底板的上方留置水平施工缝，水平施工缝的位置设置止水钢板，并且，在地下室底板的上方预留钢筋接头；根据PC外墙的钢筋定位线，初定固定PC外墙的定位筋；将PC外墙吊装至地下室底板，检测PC外墙的外观及吊环连接情况后，使用溜绳及搭钩将PC外墙缓慢下降至地下室底板的上方；为PC外墙安装斜支撑，并校正PC外墙的垂直度；在PC外墙的底部两侧设置膨胀止水条，膨胀止水条的外侧使用无收缩砂浆密封；检查PC外墙的灌浆套筒是否堵塞，并对PC外墙灌浆作业；在PC外墙与地下室底板的连接处的外侧涂抹防水涂料，在防水涂料的外侧贴铺防水卷材。
