Description

Floor drain structure suitable for old bathroom is reformed transform Technical Field The utility model relates to the technical field of sewer, in particular to a floor drain structure suitable for reconstruction of old toilets. Background At present, the old bathroom is transformed and faces a problem, in the ground renovation process, the old floor drain is inevitably required to be removed, so that the original drain pipe orifice is flush with the bathroom floor, namely, the drain pipe orifice is moved downwards, and a new floor drain cannot be installed in the ground renovation process, thereby causing trouble to the renovation work of the old bathroom. When the old bathroom is renovated, the PVC is directly inserted into the inside and outside, and the direct inserted end of the PVC is inserted into the original drain pipe orifice, so that the height of the drain pipe orifice is increased, and the requirement on the height of the drain pipe orifice during floor drain installation is met. However, this method will seriously affect the drainage flow of the drain pipe, because the drain pipe is usually a dn50 PVC pipe with an inner diameter of about 45 mm and a wall thickness of 2.5 mm, after the drain pipe orifice is directly inserted into the PVC, the inner diameter of the drain pipe is 40 mm at maximum, and the diameter of the drain core is subtracted, and the remaining drainage clear space will not meet the national standard requirement for the drainage of the floor drain, so that the toilet ponding cannot be removed in time, even overflows to the outside of the toilet. Disclosure of utility model The utility model aims to solve the technical problem of providing the floor drain structure suitable for the transformation of old toilets, which has the advantages of simple structure and convenient operation, and can solve the problem of water accumulation in the toilets caused by the fact that the drainage capacity of the floor drain cannot meet the requirement. The utility model is realized by the following technical scheme: The utility model provides a floor drain structure suitable for old bathroom is reformed transform, its includes flange pipe fitting and floor drain body, flange pipe fitting includes bellmouth, ring flange and last bellmouth down, go up the bellmouth and set up in bellmouth top and intercommunication each other down, the ring flange sets up around the bellmouth and the bellmouth meets department outer fringe down, and goes up bellmouth, ring flange and bellmouth down coaxially, the bellmouth suit is outside the drain pipe of bathroom and seal-up down, the ring flange is fixed to be placed in the bathroom subaerial, it is lower than the ceramic tile plain noodles after the bathroom is renovated to go up the bellmouth up end, floor drain body cartridge is in the bellmouth department down. Further, the flange edge is provided with a bending part which bends downwards. Preferably, the bending part is a round corner bending part, and the joint parts of the flange plate, the upper bellmouth and the lower bellmouth are all provided with transition round corners. Optimally, the upper end surface of the upper bellmouth is 3mm lower than the polished surface of the floor tile after the toilet is renovated. Preferably, the inner wall of the lower bellmouth is sleeved into the outer wall of the drain pipe orifice of the bathroom, and the inner wall of the lower bellmouth is connected with the outer wall of the drain pipe orifice of the bathroom through a PVC glue layer. Optimally, the flange plate is fixed with the original ground of the bathroom through a waterproof sealant layer. Optimally, an adhesive layer is paved on the original floor of the bathroom, the flange plate is embedded into the adhesive layer, and the floor tiles are paved above the adhesive layer. Optimally, the floor drain body and the upper bellmouth are fixed through waterproof sealant. The utility model has the beneficial effects that: According to the floor drain structure suitable for the old toilet reconstruction, the problem that a new floor drain cannot be installed in the ground renovation process due to the fact that the pipe orifice of the drain pipe moves downwards in the old toilet reconstruction process is solved by arranging the flange pipe fitting in the old toilet reconstruction process, and the floor drain structure is simple in structure and convenient to operate. In addition, because the lower bellmouth of the flange pipe fitting is sleeved outside the drain pipe of the toilet and is sealed and fixed, the problem of odor and odor resistance of the toilet caused by the fact that the drain pipe is not tightly sealed is avoided, and in the later use process, the drain water discharge amount of the floor drain is not affected, and the water accumulation of the toilet caused by the fact that the drain water discharge amount of the floor drain cannot meet the requirement is prevented.
