Description

Technical Field

[0001] The utility model relates to the technical field of building waterproofing, and particularly relates to a floor drainage structure for a water-containing room. Background Art

[0002] In a project, there is a situation where a water-containing room is arranged above a room with waterproof requirements. Usually, a double-layer structural slab construction method is adopted to meet the problem that the water-containing room and the room with waterproof requirements are not adjacent.

[0003] In the existing practice, due to the closed space between the two structural slabs where the formwork cannot be removed, foam boards and wooden boxes are often used as the bottom formwork of the upper structural slab to pour the upper structural slab. If there is water accumulation in the cavity of this structure, there will still be a risk of water seepage and leakage in the room with waterproof requirements below.

[0004] Therefore, it is necessary to design and transform the floor drainage structure for a water-containing room. Content of the Utility Model

[0005] To solve the problems raised in the above background art, the purpose of the present utility model is to provide a floor drainage structure for a water-containing room, which has the advantage of improving the waterproof effect, and solves the problem that in the existing practice, due to the closed space between the two structural slabs where the formwork cannot be removed, foam boards and wooden boxes are often used as the bottom formwork of the upper structural slab to pour the upper structural slab. If there is water accumulation in the cavity of this structure, there will still be a risk of water seepage and leakage in the room with waterproof requirements below.

[0006] To achieve the above purpose, the present utility model provides the following technical solution: A floor drainage structure for a water-containing room, including a building wall;

[0007] A reinforced concrete structure slab arranged inside the building wall;

[0008] The number of the reinforced concrete structure slabs is two. A cavity is arranged inside the reinforced concrete structure slabs. A waterproof coating film is coated on the bottom of the cavity. A large cup-shaped finished hydrophobic plate is laid on the top of the waterproof coating film. A drain pipe is arranged on the right side of the building wall. One end of the drain pipe close to the building wall penetrates through the building wall and is communicated with the cavity.

[0009] Preferably, a cement mortar layer is laid on the top of the reinforced concrete structure slab, and the waterproof coating film is coated on the top of the cement mortar layer.

[0010] Preferably, the cup of the large cup-shaped finished hydrophobic plate faces upward. The compressive strength of the large cup-shaped finished hydrophobic plate is greater than 300 kN per meter, and the height of the large cup-shaped finished hydrophobic plate is between 20 - 50 millimeters.

[0011] Preferably, an inner side of the building wall is coated with a waterproof coating located at a top of a reinforced concrete structural slab. A nano coiled material is laid inside the building wall and located inside the waterproof coating. An inner surface of the nano coiled material is fixedly connected to a surface of the waterproof coating.

[0012] Preferably, an impermeability grade of the reinforced concrete structural slab is greater than P6 level.

[0013] Preferably, a model ratio of the cement mortar layer is M15, and the waterproof coating film is greater than 1.5 cm.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. By replacing a foam board and a wooden box, which originally served as a formwork for a structural slab, with a finished HDPE large cup-shaped hydrophobic board, and embedding a drain pipe at a position where the finished HDPE large cup-shaped hydrophobic board intersects with the building wall to drain to the outside of a closed cavity, the present utility model avoids long-term water accumulation and water storage inside the cavity, which may cause seepage and leakage of the lower structural slab.

Apparently, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] As Figures 1 to 3 shown, a water drainage structure for a floor slab in a water-containing room provided by the present utility model includes a building wall 1;

[0022] a reinforced concrete structural slab 2 arranged inside the building wall 1;

[0023] There are two reinforced concrete structural panels 2, a cavity 3 is arranged on the inner side of the reinforced concrete structural panels 2, the bottom of the cavity 3 is coated with a waterproof coating 4, a large cup-mouthed finished hydrophobic board 5 is laid on the top of the waterproof coating 4, a drain pipe 6 is arranged on the right side of the building wall 1, and one end of the drain pipe 6 close to the building wall 1 passes through the building wall 1 and is connected with the cavity 3.

[0024] refer to Figure 3 A cement mortar layer 7 is laid on the top of the reinforced concrete structural board 2, and a waterproof coating 4 is coated on the top of the cement mortar layer 7.

[0025] refer to Figure 2 The cup mouth of the finished hydrophobic plate 5 with a large cup mouth faces upward, the compressive strength of the finished hydrophobic plate 5 with a large cup mouth is greater than 300 kilonewtons per meter, and the height of the finished hydrophobic plate 5 with a large cup mouth is between 20 and 50 mm.
