Sectional combined floor drain double-layer drainage and moisture removal device and construction method thereof

Abstract

The invention relates to a sectional combined floor drain double-layer drainage and moisture removal device and a construction method thereof. The sectional combined floor drain double-layer drainageand moisture removal device comprises a floor drain insertion pipe and a floor drain sleeve assembly, wherein the floor drain insertion pipe is inserted into an inner upper part of the floor drain sleeve assembly; the floor drain sleeve assembly comprises a sleeve main body, a water stop ring tray, and a sleeve base plate. The sectional combined floor drain double-layer drainage and moisture removal device is characterized in that a sleeve connecting plate and a water filter ring are arranged outside an upper opening of a floor drain sleeve, a flow guide groove is formed on a periphery of thesleeve connecting plate, and a water stop ring capable of improving an anti-leakage performance is arranged on the outer side of the sleeve main body. The sectional combined floor drain double-layer drainage and moisture removal device has the advantages that besides effectively improving the anti-leakage performance, by the adoption of the device in a toilet, a shower room, a terrace and the like, the drying of a waterproof layer can be effectively guaranteed, a water accumulation and mildew of the waterproof layer is prevented, a door frame is prevented from being deformed and rotten, and apeculiar smell generated in the toilet, the shower room or the terrace is avoided. The sectional combined floor drain double-layer drainage and moisture removal device can not only meet requirements of industrial uses, but also meet the requirements of coarse and intensive decoration projects such as houses, hotels, public buildings and the like, and has the advantages of being flexible in installation and combination and wide in application range.

Description

technical field [0001] The invention belongs to the technical field of building interior facilities, and in particular relates to a segmented combined floor drain double-deck drainage device and a construction method. Background technique [0002] At present, the floor drains that are often used in projects with a large amount of exposed water such as toilets, showers or balconies are in the majority of two-stage structures. The floor drain casing is pre-embedded in the structural floor slab after pasting the water-swellable water-stop strip, and its upper part is about 10 cm higher than the structural slab, and the floor drain intubation is installed during the construction of the floor surface. However, in actual construction, the outer wall of the floor drain intubation and the inner wall of the floor drain casing are not completely fitted, and there is a certain gap; after the floor drain intubation and the floor drain casing are installed and plugged, the closed positio...

Problems solved by technology

Taking the bathroom as an example, there is a protective layer and a surface layer above the waterproof layer. The part where it meets the wall will crack due to structural deformation, thermal expansion and contraction, etc., and water will penetrate into the waterproof layer along the cracks, or other reasons. Ground leakage, because the floor drain sleeve and the waterproof layer are completely sealed, the seepage water accumulates between the waterproof layer and the protective layer and cannot be discharged. If it accumulates for a long time, it will cause the wall and floor to become damp and moldy, produce peculiar smell, and the wooden door frame and bag mouth of the bathroom will return to moisture and rot.
