Roughening tool for precast concrete laminated slab component

A roughening tool for a precast concrete laminated slab member belongs to building facilities and is characterized by comprising a full-length round steel pipe, a plurality of sections of sleeves aresleeved outside the full-length round steel pipe, and a steel plate is arranged between every two adjacent sections of sleeves. The steel plates are provided with round holes, the diameter of the round holes of the steel plates is slightly larger than that of the full-length round steel pipes, the diameter of the sleeves is slightly smaller than the width of the steel plates, the steel plates penetrate through the full-length round steel pipes through the round holes, and the steel plates are separated through the sleeves to form a whole. The problems that traditional manual galling is low inefficiency, and construction quality is difficult to guarantee can be solved, the construction efficiency and the construction quality of the prefabricated concrete laminated slab structure are guaranteed, later maintenance co
