Jig for ensuring grouting fullness of vertical sleeve for prefabricated structure and working method
The invention discloses a jig for ensuring the grouting fullness of a vertical sleeve for a prefabricated structure and a working method, and relates to a prefabricated shear wall installed on a lower-layer cast-in-place concrete plate. A grouting sleeve is arranged at the bottom of the prefabricated shear wall, an upper connecting steel bar extending into the grouting sleeve is arranged in the prefabricated shear wall, and a lower connecting steel bar extending into the grouting sleeve is arranged on the lower-layer cast-in-place concrete plate; the upper part and the lower part of the grouting sleeve are respectively provided with a grouting pipeline and a grout outlet pipeline which are inclined upwards and extend out of the prefabricated shear wall; and a horizontal joint is arranged between the bottom of the prefabricated shear wall and the lower-layer cast-in-place concrete plate, and peripheral bed mortar is arranged at the outer edge of the horizontal joint by a circle to define a closed cavity. The jig has the advantages that full grouting of a grout outlet part and parts below the grout outlet part can be accurately guaranteed, operation is convenient, the grouting quality is good, one-time forming is achieved, supplementary grouting is not needed, plumpness detection does not need to be conducted on the grout outlet part, and cost is saved.
本发明公开了一种用于预制结构确保竖向套筒灌浆饱满度的治具及工作方法，涉及安装于下层现浇混凝土板上的预制剪力墙，预制剪力墙底部设置有灌浆套筒；预制剪力墙内设置有延伸入所述灌浆套筒内的上连接钢筋，下层现浇混凝土板上设置有延伸入灌浆套筒内的下连接钢筋；灌浆套筒的上部和下部分别具有向上倾斜并延伸出预制剪力墙的注浆管道和出浆管道；预制剪力墙的底部与下层现浇混凝土板之间具有水平接缝，水平接缝的外缘一圈设置有周边座浆，围合构成封闭腔体。本发明的优点是:可精准确保出浆口部位及以下部位灌浆饱满，操作方便、灌浆质量好，一次成型，无需补灌，无需对出浆口部位进行饱满度的检测，节省成本。
