Defect repairing method for bottom concrete of self-supporting box of hollow floor system
The invention provides a defect repairing method for bottom concrete of a self-supporting box of a hollow floor system. The defect repairing method comprises the following steps: chiseling away concrete at a defect part at the bottom of the self-supporting box; according to the size of the self-supporting box and the size of concrete on the upper side of the self-supporting box, a grouting piece is manufactured; a grouting piece containing hole used for containing the grouting piece and an observation hole are formed in the self-supporting box and the position, extending to the upper side of the self-supporting box, of the concrete; erecting a template at the bottom of the self-supporting box; and a manufactured grouting piece is installed in the grouting piece containing hole, repairing slurry is injected into the grouting piece, and the repairing slurry enters the defect part at the bottom of the self-supporting box through the grouting piece till the space containing the repairing slurry is filled with the repairing slurry. By means of the repairing method, the problems that according to an existing repairing method, the bonding degree of cement mortar and the bottom of the self-supporting box is not high after repairing, the maintenance quality is poor, the appearance perception is poor, and efficiency is low can be solved.
本发明提供一种空心楼盖自承箱底部混凝土的缺陷修补方法，包括：对自承箱底部的缺陷部位的混凝土进行凿除；根据所述自承箱以及所述自承箱上侧混凝土的尺寸，制作注浆件；在所述自承箱以及延伸至所述自承箱上侧的混凝土的位置设置用于容纳所述注浆件的注浆件容纳孔以及观察孔；在所述自承箱底部架设模板；将制作好的注浆件安装到所述注浆件容纳孔中，并将修补浆料注入到所述注浆件，所述修补浆料通过所述注浆件进入到所述自承箱底部的缺陷部位，直至所述修补浆料注满容纳修补浆料的空间。利用本发明，能够解决现有的修补方法存在修补后水泥砂浆与自承箱底部粘结度不高、维修质量差、外形感观差，并且效率低等问题。
