Prefabricated column and cast-in-place concrete structure sleeve inverted insertion type one-time grouting construction method
The invention provides a prefabricated column and cast-in-place concrete structure sleeve inverted insertion type one-time grouting construction method. The method comprises the steps that 1, a cast-in-place concrete structure is constructed, the cast-in-place concrete structure is provided with cast-in-place piles and a cast-in-place floor, sleeves are arranged at the upper ends of cast-in-place pile column ribs, cup openings of the sleeves are flush with the top end of the cast-in-place floor, the sleeves are provided with upper-end slurry openings and lower-end slurry openings, the cast-in-place piles are sequentially constructed, the sleeves are mounted, positioning plates at the upper ends of the sleeves are mounted and the cast-in-place floor is constructed; 2, the positioning plates are dismounted; 3, the limiting plates are constructed; 4, a prefabricated column is hoisted, a joint grout outlet pipe is arranged in the prefabricated column, connecting ribs are arranged at the lower ends of prefabricated column ribs and are inserted into the sleeves one by one; 5, the prefabricated column is supported; 6, grouting construction is conducted in the sleeves one by one, so that grouting materials overflow from a grout outlet pipe, and grouting is conducted on the last sleeve till the grouting materials are discharged from the joint grout outlet pipe; and 7, construction is completed. According to the construction method, air in the sleeves and a joint in assembly type construction can be discharged easily, grouting fullness is guaranteed, and the method has the advantages of being high in construction quality, good in effect and easy to operate.
本发明提出一种预制柱与现浇砼结构套筒倒插式一次灌浆施工方法，步骤有：1、现浇砼结构施工；现浇砼结构具有现浇桩和现浇楼板；其中现浇桩柱筋上端设有套筒、其杯口与现浇楼板顶端持平，套筒上具有上端浆口和下端浆口；依次施工现浇桩、安装套筒、套筒上端安装定位板、施工现浇楼板；2、拆除定位板；3、施工限位板；4、吊装预制柱，预制柱内设有接缝出浆管；预制柱柱筋下端具有连接筋并一一插于套筒内；5、支撑预制柱；6、逐根向套筒内进行灌浆施工，使灌浆料由出浆管溢出，最后一根套筒灌浆至灌浆料由接缝出浆管出浆；7、完成施工。本发明有利于装配式施工中套筒内及接缝内空气的排出，确保灌浆饱满度，具有施工质量高、效果好和易于操作的特点。
