Abstract

The invention provides a prefabricated column and cast-in-place concrete structure sleeve inverted insertion type secondary 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, 1.1, the cast-in-place piles are constructed; 1.2, the sleeves are installed at the upper ends of the cast-in-place pile column ribs; 1.3, positioning plates are mounted to positions the upper ends of the sleeves; and 1.4, the cast-in-place floor are constructed; 2, the positioning plates are dismounted; 3, limiting plates are constructed; 4, the prefabricated column is hoisted, the lower end of a prefabricated pile column rib is provided with connecting ribs, and a joint grouting pipe and a joint grout outlet pipe are pre-buried in the lower portion in the prefabricated column; 5, the sleeves are grouted from cup openings of the sleeves, and the connecting ribs of the precast pile are inserted into the sleeves in a one-to-one correspondence manner; 6, joint grouting construction is carried out after the joint base mortar construction; and 7, all construction is completed. By means of the secondary grouting construction procedure, the complexity of pipeline pre-burying and grouting operation in sleeve grouting construction is effectively avoided, and the method has the advantages of being high in construction quality, good in effect, rapid and efficient.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a sleeve-inverted secondary grouting construction method for prefabricated columns and cast-in-situ concrete structures. Background technique [0002] There are more or less cast-in-place concrete structures in the prefabricated building structure, and the connection forms between the cast-in-place concrete structure and the prefabricated components can be steel sleeve grouting connection, steel grout anchor lap joint and post-cast concrete steel bar lap joint. Compared with the other two overlapping methods, the steel sleeve grouting connection is superior to the other two in terms of mechanical properties of joints, construction quality control and reliability. Usually, in the steel bar sleeve grouting connection structure, the sleeve is located in the upper structure, the cup mouth is downward, the column bar is located in the lower structure, inserted into the sleeve upw...
