A secondary drainage device installed on the side of the floor drain downpipe

Abstract

A secondary drainage device installed on the side of the downpipe of the floor drain, including a main body, a cable tie, a positioning head, and a filter block; it is characterized in that a long through hole is arranged in the middle of the main body, and a support is arranged in the middle of the long through hole, and the long side of the main body There is an upper lever and an upper positioning hook; a lower lever and a lower positioning hook; one end of the main body is connected with a cable tie with a positioning head, and the other end is connected with a cable tie with a barb tooth and a plug; when After the barbed teeth on the cable tie enter the socket, the cable tie with the barbed teeth can only move in one direction in the socket under the action of the barb; press the barb shift block to make the barb back to the point where it does not touch the barb The state of the teeth, the cable tie with inverted teeth can move in the opposite direction in the socket; the filter block can be placed in the limited space formed by the upper lever, the upper positioning hook, the lower lever, and the lower positioning hook to prevent sediment It enters into the round hole through the filter block and the long through hole; the invention is especially suitable for the renovation project of adding secondary drainage to the bathroom without secondary drainage.

Description

technical field [0001] The invention relates to the field of building water supply and drainage, in particular to a secondary drainage device installed on the side of a floor drain downpipe. Background technique [0002] In 2008, the Ministry of Housing and Urban-Rural Development issued the "Notice on Further Strengthening the Management of Residential Decoration" (Jianzhi [2008] No. 133), pointing out that it is necessary to improve support policies and promote fully furnished houses. Since the implementation of finely decorated houses, there have been a large number of leakage maintenance problems in the bathrooms of the delivered houses, and the leakage of bathrooms has plagued developers and house buyers. [0003] In order to improve the construction efficiency of newly-built commercial residential fully furnished houses and reduce costs, the toilets of fully furnished houses basically adopt the method of different-layer drainage; fully furnished houses have less leakag...

Problems solved by technology

[0006] Patent No.: ZL 201410071557.4 discloses "A Secondary Drainage Construction Method for Toilets". The secondary drainage method is to make the traditional caisson waterproof into a waterproof layer with a slope, and drill a 10mm-diameter hole on the root of the water pipe under the washbasin. In order to achieve the purpose of secondary drainage, but the drilling of this method will have a damaging effect on the bonding between the waterproof layer and the water pipe in the waterproof caisson, and the mold between the waterproof layer and the water pipe will cause mildew over time. If the two are separated, water will eventually leak to the next layer along the crevice to form water leakage. This method is difficult to ensure long-term waterproof quality

[0007] Patent No. ZL202010386896.7 "A Secondary Floor Drain Connection Structure and Construction Technology for Sunken Toilets" requires the production of vertical water guide wells. The construction is complicated and a special underground floor drain needs to be inserted into the embedded casing, which reduces the size of the original water pipe. diameter, affecting normal drainage

[0008] Patent No.: ZL 201920878888.7 "A Concealed Floor Drain to Prevent Indoor and Exterior Walls and Floors from Wetting and Preventing Saturated Water from Overflowing". This technology will greatly reduce the diameter of the original water pipe and affect normal drainage; The ground waterproof structure can also achieve secondary drainage, but this technology will also greatly reduce the diameter of the water pipe, affecting normal drainage

[0009] Patent No.: ZL 201720652712.0 "Drainer and Drainage System", which can realize secondary drainage. This technology already has a patented product, but to use this patented product, it is first necessary to cut off the original floor drain downpipe against the waterproof layer, and then insert the product into the floor drain downpipe Use; cutting the original floor drain downpipe against the waterproof layer will affect the adhesion between the waterproof layer and the floor drain downpipe, and this patented product will greatly reduce the diameter of the original water pipe: for example, the cross-sectional area of ​​the floor drain downpipe with an inner diameter of 75mm is 44.18 square meters cm, the minimum diameter of the 75-type product is only 56mm, and the cross-sectional area is only 24.62 square centimeters, and the water flow is reduced by nearly half; while the cross-sectional area of ​​the floor drain with an inner diameter of 50mm is 19.63 square centimeters, the minimum diameter of the 50-type product is only 34mm, the cross-sectional area is 9.07 square centimeters, and the water flow is reduced by half. When it takes a long time to discharge the full design load, there is obviously a safety hazard.
