On-site wet connection construction method of prefabricated cover beam
The invention discloses an on-site wet connection construction method of a prefabricated cover beam and belongs to the field of bridge engineering construction. The method is mainly invented for solving the problem of low efficiency of a construction method for cast-in-place of a capping beam by adopting a vertical mold. A capping beam reserved opening is formed in a pier body, and after a bottom die and a template of the reserved opening are installed, capping beam steel bars are bound. Pre-embedded sleeves are arranged at the contact positions of main reinforcements of the cover beam and the reserved opening formwork, pre-embedded sleeve steel is connected to the reinforcements, connecting reinforcements of the pre-embedded sleeves are welded to the main reinforcements of the cover beam, two sleeves are pre-embedded at the bottom of the position of the cover beam, side formwork installation of the cover beam is conducted after the steel reinforcements of the cover beam are bound, and the cover beam is constructed in a prefabricating field. A small platform formwork is additionally arranged at the top end of the pier column formwork, steel bars are embedded in a small platform, and steel bars extending into the bent cap are reserved at the top end of the pier column. And after pier column concrete pouring and curing are completed, the bent cap is hoisted, and the steel bars in the reserved opening of the bent cap are connected. And after all the steel bars are bound, the reserved opening is wetted by spraying water, and wet connection operation is carried out on site. The construction efficiency is improved.
一种预制盖梁现场湿接的施工方法属于桥梁工程施工领域。主要是为解决采用立模现浇盖梁的施工方法效率低的问题而发明的。在墩身设置盖梁预留口，底模及预留口的模板安装完毕后，进行盖梁钢筋的绑扎。在盖梁主筋与预留口模板接触处的位置设置预埋套筒，预埋套钢连接在钢筋上，预埋套筒的连接钢筋焊接在盖梁主筋上，在盖梁位置底部预埋两个套筒，盖梁钢筋绑扎完毕后进行盖梁的侧模安装，盖梁在预制场内施工，墩柱模板顶端加设小平台模板，在小平台预埋钢筋，墩柱顶端预留伸入盖梁的钢筋。墩柱混凝土浇筑养护完毕后，盖梁吊装，对盖梁预留口内钢筋进行连接。钢筋全部绑扎完成后，对预留口进行喷水湿润，现场进行湿接作业。优点是提高施工效率。
