The invention provides a grouting plugging structure and method for connecting nodes of prefabricated columns. The invention changes the original manual control plugging method to reserving caulking grooves on the floor surface, and the prefabricated columns on the lower layer are hoisted on the prefabricated columns on the upper layer. After the completion, use the caulking groove to plug the seam, avoid the leakage of grout in the process of grouting the sleeve in the later stage, ensure the quality of the plugging seam, ensure the grouting effect, ensure the quality of the vertical steel grouting connection, simplify the post-processing steps, save the cost, and improve the Construction efficiency and quality of prefabricated buildings.
Description
technical field [0001] The invention relates to a prefabricated column connecting node grouting plugging structure and method. Background technique [0002] With the large-scale application of prefabricated concrete structures, during the construction of prefabricated buildings, vertical reinforced sleeve grouting is required after the upper component columns are hoisted and installed. There is a 20mm gap between the upper and lower prefabricated columns. The quality of the plugged seam of the component directly affects the quality of the grouting. However, at present, the width of the plugged seam is mostly controlled by hand. This method is not uniform in the width of the plugged seam, and the quality is difficult to control. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a prefabricated column connecting node grouting plugging structure and method, which can avoid the problems of manual control of uneven width of plug joints, diffic...
