Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a toilet drainage structure for building engineering. Background Technology

[0002] Bathroom drainage systems mainly include two types: same-floor drainage and cross-floor drainage. Same-floor drainage means that the drain branches and horizontal drain pipes of the sanitary fixtures are on the same floor and do not penetrate the floor slab to enter the floor below. Cross-floor drainage means that the drain branches of the sanitary fixtures penetrate the floor slab and connect under the ceiling slab of the bathroom in the lower-floor apartment.

[0003] Bathroom drainage systems typically involve drainage from the wet area (shower area), the toilet in the dry area, the floor in the dry area, and the sink in the dry area. If the gaps between the wet and dry area floors are not waterproofed, water will seep under the tiles in both areas and cannot drain through the floor drain. This creates a problem during use, and over time, water can easily seep along the walls, causing dampness in adjacent rooms. Summary of the Invention

[0004] The purpose of this utility model is to provide a bathroom drainage structure for building engineering, which has the function of draining water that has seeped under the floor tiles.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a bathroom drainage structure for building engineering, including a ground layer, a wall connecting the ground layer, a waterproof layer between the ground layer and the wall, a water-blocking strip on the waterproof layer that distinguishes between dry and wet areas, a cement mortar layer on the waterproof layer, a floor tile layer on the cement mortar layer, a first drain pipe on the ground layer located in the dry area, and a second drain pipe on the ground layer located in the wet area. The two ends and the bottom of the water-blocking strip are respectively coated with waterproof sealant. A first water-diverting slope layer located in the dry area is provided between the ground layer and the waterproof layer, and a second water-diverting slope layer located in the wet area is provided between the ground layer and the waterproof layer. A first water-diverting pipe is pre-embedded in the ground layer and extends to the lowest point of the first water-diverting slope layer on its periphery of the first drainage pipe. A second water-diverting pipe is pre-embedded in the ground layer and extends to the lowest point of the second water-diverting slope layer on its periphery of the second drainage pipe. Anti-clogging components to prevent cement mortar layer from falling off are respectively provided at the openings of the first water-diverting pipe and the second water-diverting pipe.

[0006] A further feature of this invention is that the first water inlet pipe extends downward at an angle toward the first drain pipe, and the second water inlet pipe extends downward at an angle toward the second drain pipe.

[0007] A further feature of this invention is that: a first stepped groove is provided at the opening of the first water inlet pipe, and a second stepped groove is provided at the opening of the second water inlet pipe; the anti-clogging component includes a filter top cover for embedding in the first or second stepped groove, a sealing ring provided at the bottom of the filter top cover, and a strip-shaped water inlet groove is provided in a circumferential array on the periphery of the filter top cover.

[0008] A further feature of this invention is that the filter top cover includes an embedded tube portion for embedding in a first stepped groove or a second stepped groove, a top cover portion disposed on the embedded tube portion and extending out of the first stepped groove or the second stepped groove, and the strip-shaped water inlet groove is disposed between the bottom of the top cover portion and the periphery of the embedded tube portion.

[0009] A further feature of this invention is that a flexible waterproof sleeve is fitted onto the first drain pipe and the second drain pipe, and the inner ring and bottom of the flexible waterproof sleeve are coated with sealant for bonding to the periphery of the first drain pipe or the second drain pipe and the waterproof layer.

[0010] In summary, the beneficial effects of this utility model are:

[0011] 1. By setting up the first water diversion slope layer and the second water diversion slope layer, water that has seeped into the ground can flow to the opening of the first water diversion pipe and the opening of the second water diversion pipe, and then be discharged along the first water diversion pipe and the first drainage pipe, or along the second water diversion pipe and the second drainage pipe. At the same time, during the process of setting the cement mortar layer, the anti-clogging component can prevent the cement mortar layer from falling into the first water diversion pipe and the second water diversion pipe, and ultimately has the function of draining the water that has seeped into the floor tiles.

[0012] 2. The inclined design of the first and second water inlets facilitates drainage.

[0013] 3. When the anti-clogging component is set, the filter top cover includes the embedded pipe part and the top cover part. The strip water inlet groove is set between the bottom of the top cover part and the periphery of the embedded pipe part. At this time, cement mortar is not easy to fall into the strip water inlet groove.

[0014] 4. By setting up a flexible waterproof sleeve, and applying sealant to the inner ring and bottom of the flexible waterproof sleeve for bonding to the periphery of the first or second drain pipe and the waterproof layer, the waterproof sealing between the first drain pipe and the ground layer, and between the second drain pipe and the ground layer is further guaranteed.
