Description

Technical Field

[0001] The invention relates to the technical field of floor drain installation, in particular to a balcony floor drain pre-buried in a same-layer drainage node structure of a composite plate. Background Art

[0002] A floor drain is a drainage device installed on the ground, mainly used to drain water or wastewater from the ground. It is commonly found in bathrooms, kitchens, laundry rooms, etc. The main function of a floor drain is to prevent water from accumulating on the ground and ensure that the ground is dry and clean.

[0003] At present, the drainage systems of domestic buildings are basically divided into different-layer drainage and same-layer drainage. Different-layer drainage refers to the sewage horizontal pipe connecting the bathroom sanitary ware, which needs to pass through the floor to the residents' home downstairs and then connect to the sewage riser; the traditional same-layer drainage adopts the same-layer drainage of the lower floor. The above-mentioned different-layer drainage and same-layer drainage have the following problems and shortcomings: 1. Pipe blockage causes indoor water accumulation; 2. Balcony / bathroom drainage noise is loud; 3. There is a smell at the floor drain. Summary of the invention

[0004] The object of the present invention is to provide a balcony floor drain pre-buried in the same-layer drainage node structure of the composite plate, which effectively solves the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions.

[0006] A balcony floor drain is pre-buried in a same-layer drainage node structure of a composite slab, comprising a prefabricated floor slab and a jellyfish floor drain, a reserved hole is arranged on the prefabricated floor slab, a drainage riser is arranged inside the reserved hole, a jellyfish floor drain is arranged on the upper surface of the prefabricated floor slab, a drainage pipe is connected to the outer surface of the jellyfish floor drain, and the drainage pipe is connected to the drainage riser through a three-way joint. A casting layer is cast on the upper surface of the prefabricated floor slab, a heightened anti-slope is arranged on the upper surface of the casting layer, a first waterproof layer is arranged on the upper surface of the casting layer located inside the heightened anti-slope, a second waterproof layer is arranged on the outer surface of the heightened anti-slope, and a building surface layer is arranged on the upper surface of the casting layer located outside the heightened anti-slope.

[0007] It can be seen that by pre-burying the jellyfish floor drain and the drainage pipe in the casting layer and connecting them to the drainage riser, not only can the drainage pipe be hidden, but also the noise during drainage can be reduced. In addition, since a water trap is arranged on the drainage pipe, odor can be effectively avoided. By raising the anti-sill and setting the second waterproof layer, when the pipe is blocked and water accumulates, the accumulated water can be gathered on the inner side of the raised anti-sill to avoid leakage to the outside, causing water accumulation indoors and causing damage to furniture. In addition, by setting the first waterproof layer, the accumulated water can be prevented from leaking downward to the residents downstairs, and it has good waterproof performance.

[0008] Furthermore, the first waterproof layer includes a thick polyurethane waterproof coating arranged on the upper surface of the casting layer, the upper surface of the thick polyurethane waterproof coating is provided with a fine stone concrete slope, the upper surface of the fine stone concrete slope is provided with a thick polymer cement waterproof coating, and the upper surface of the thick polymer cement waterproof coating is provided with a thick epoxy floor paint surface layer.

[0009] Furthermore, the second waterproof layer includes a thick waterproof layer arranged on the outer surface of the raised anti-ridge, an adhesive bonding layer is arranged on the outer surface of the thick waterproof layer, and a thick ceramic tile layer is arranged on the upper surface of the adhesive bonding layer.

[0010] Furthermore, the drainage pipe is arranged to be inclined from high on the left to low on the right.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows.

[0012] 1. The present invention embeds the jellyfish floor drain and the drainage pipe into the casting layer and connects them to the drainage riser, which not only hides the drainage pipe, but also reduces the noise during drainage. In addition, since the drainage pipe is provided with a water trap, the backflow of odor can be effectively avoided. By raising the anti-sill and setting the second waterproof layer, when the pipeline is blocked and water accumulates, the accumulated water can be gathered on the inner side of the raised anti-sill to avoid leakage to the outside to cause water accumulation indoors and damage to furniture. In addition, by setting the first waterproof layer, the accumulated water can be prevented from leaking downwards to the residents downstairs, and the present invention has good waterproof performance.

[0019] When in use, the 60mm thick prefabricated bottom plate of the prefabricated floor 100 is used as the bottom mold for pre-embedded jellyfish floor drain 103. After the prefabricated floor 100 is hoisted and installed in place, the jellyfish floor drain 103 and the drain pipe 104 are pre-embedded between the floor steel bars, and the drain pipe 104 is connected to the drain riser 102 through a three-way joint 105. Then, concrete is poured to form a casting layer 106. After the casting of the casting layer 106 is completed, combined with the position of the jellyfish floor drain 103 and the installation position of the laundry cabinet, a heightened anti-ridge 107 is made around the jellyfish floor drain 103 to form a "drainage basin". The height of the heightened anti-ridge 107 is 50mm. Then, a second waterproof layer 300 is arranged on the outer surface of the heightened anti-ridge 107, and a first waterproof layer 200 is arranged in the inner area of ​​the heightened anti-ridge 107 to form a waterproof structure.
