step three: before hoisting, carrying out component size rechecking and quality appearance inspection;
step four: measuring and paying off, and positioning a column size line;
step five: cleaning and sprinkling water for wetting the column bottom, and adjusting the elevation of the column bottom;
step six: installing prefabricated columns with corresponding numbers;
step seven: hoisting corresponding prefabricated mortise-tenon type nodes, and correspondingly inserting vertical slots of the nodes into lower fixing plates on the prefabricated columns;
step eight: hoisting the precast beam to a specified elevation, aligning the mounting holes of the precast mortise-tenon joint, and then inserting and temporarily fixing;
step nine: repeating the work of the step six, the step seven and the step eight;
step ten: pouring ultra-early-strength ultra-high-strength grouting material, screwing up the fixing screws, and reliably connecting the precast beams, the columns and the precast mortise-tenon joints in a bolting way;
step eleven: and (5) finishing splicing the prefabricated nodes.
