Description

Modularized same-floor drainage device for high-rise building and installation method thereof

Technical Field

The invention relates to the technical field of building water supply and drainage devices, in particular to a modular same-floor drainage device for high floors and an installation method thereof.

Background

The drainage system of the existing high-rise building mostly adopts a double-riser drainage system, a riser connecting pipe and a breather pipe connecting pipe are usually pre-embedded at the positions of the drainage risers and the breather pipes penetrating through a floor slab so as to connect the drainage risers and the breather pipes of the floor and the lower floor, and a communicating piece is adopted to communicate the riser connecting pipe with the breather pipe connecting pipe; however, in the specific application process, the following disadvantages occur: 1) In order to avoid leakage, the waterproof layer is usually turned upwards along the pipeline and provided with a water blocking platform, so that the indoor floor arrangement is messy and unattractive, the decoration is inconvenient, the accumulated water on the floor cannot be directly drained away, and the hidden danger of leakage still exists in a sinking area; 2) In the same-floor drainage scheme of the sink toilet, because the trap of the sewage pipe is embedded in the interlayer of the floor, the shape of a cleaning opening of the sewage pipe is the same as that of a nominal shape, blockage can not be removed and cleared, and once the sewage pipe is blocked, a lot of troubles and hidden dangers are brought to a user; thirdly, water seals are independently arranged at the water outlets of the floor drain, the bathtub, the hand basin, the mop pool and the like, and the water seal at one water outlet can cause indoor odor return and harm health after being dried; 3) Along with the popularization of the housing industrialized construction mode, the installation mode of connecting the drain pipe by adopting the pipe section pipe fitting splicing and bonding mode on site has the defects that the joint quality cannot be ensured and the construction period is long; 4) In the prior art, a sewage pipe is embedded in a ground layer above a structural floor slab, so that the thickness of the ground layer of a building is large, the self-weight load of the structure is increased, and materials are wasted; 5) At present, a specially-arranged vent pipe is connected with a vertical drainage pipe by adopting an H-shaped communicating pipe, sewage vertically spirally flows along the pipe wall in the vertical drainage pipe, an inertial water curtain or a water film is easily formed at an opening of the H-shaped communicating pipe to plug a connecting vent pipe opening, so that water enters the H-shaped connecting pipe and enters the vent pipe, the ventilation effect is poor, and water enters the vent pipe; 6) The installation distance between the vertical pipe connecting pipe and the vent pipe connecting pipe is required, so that the center distance between the drainage vertical pipe and the vent pipe pipeline must meet the requirement of a certain size, usually not less than 260mm, the occupied space area of the pipeline is large, a reserved hole of a floor slab is formed because the two vertical pipes must penetrate through a structural floor slab, the distance between two holes is small, and a waterproof layer between the two pipelines is very difficult to construct and is often a leakage multiple-occurrence area.

In order to solve the above problems, people are always seeking an ideal technical solution.

The design of the flanging 12 of the header 11 forms a lap joint mechanism of flat joint → downward turnover with the waterproof layer 51 of the toilet, so that the waterproof layer 51 can effectively cover the installation gap between the header and the floor slab installation hole without adopting concrete for filling; meanwhile, the end part of the waterproof layer 51 is positioned on the header top cover 11, and the height difference is formed between the waterproof layer and the waterproof layer on the ground, so that the ground accumulated water can flow onto the header top cover 11 in a guiding manner and is discharged into the header 10, and the accumulated water cannot flow backwards from the bonding seam between the waterproof layer 51 and the header top cover 11, thereby thoroughly solving the problem of accumulated water leakage at the position where a pipeline passes through a floor slab in the prior art.

It should be particularly noted that it will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, such as: the concrete connection position of the water seal tank and the header of the catchment tank and the shape of the water seal tank, the water seal tank adopts a water seal cylinder, a water seal bent pipe, a partition plate or other water seal components in the prior art, the position distribution of the water seal tank and a sewage pipe in the catchment tank, the shape of the sewage pipe, the position distribution of a water drainage hole on the header of the catchment tank, the structures and the shapes of an upper vent pipe and a lower vent pipe, the positions of the upper vent pipe and the lower vent pipe relative to the catchment tank and other technical characteristics are deformed. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
