The utility model discloses a fixing device for a turnover
floor slab sleeve. The fixing device comprises angle steel, a fixing device and a fixing device, the fixing
assembly is installed at the upper end of the angle steel, the fixing
assembly comprises a pair of fixing nuts and a pair of screws, the fixing nuts are fixed to the left side and the right side of the angle steel correspondingly, and the screws are fixed to the left side and the right side of the angle steel correspondingly. After the sleeve is placed, the angle steel on the floor is fixed through the fixing
assembly, the square waste formwork is placed in the center of the upper portion of the sleeve and then screwed through the movable nut,
friction force is formed between the sleeve and the floor, and therefore the effect of preventing the sleeve from moving is achieved, the quality effect can be guaranteed, and cost can be effectively reduced. And meanwhile, the fixing mode considers the existing conventional materials on site, the materials are convenient to take, the cost is further reduced by turnover use, and the requirement of green construction is met by using the waste template.
