It should be noted that, without conflict, the embodiments of the present application and features of the embodiments may be combined with each other.

Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present application, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.

In the present application, unless explicitly specified and limited otherwise, the terms "mounted," "connected," "secured," and the like are to be construed broadly and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art according to the specific circumstances.

The modular building takes standardization and modularization as principles, is different from a cast-in-place concrete floor slab, has little or no structural descending plate, and can effectively reduce the number of indoor beams and columns. Through the fixed division of prefabricated module modulus in the modularization building, can reduce prefabricated floor component kind by a wide margin, be favorable to prefabricated module's standardization, unification, accord with the development requirement of assembled building.

At present, most of bathroom drainage adopts a caisson type same-layer drainage technology and a non-falling plate same-layer drainage technology based on a composite floor slab.

The drainage pipe of the toilet is laid in the caisson area by adopting the mode that the structural descending plate is formed in the same-layer drainage of the toilet, and is connected into the vertical pipe for drainage after being converged. Wherein, the bottom of the caisson is provided with a secondary drainage floor drain which is connected with a special drainage vertical pipe or an existing sewage vertical pipe to realize accident drainage. The technology needs to cooperate with the descending plate from the structure, and has small limitation on the type of sanitary appliance. But can compress the clean height of the toilet, and simultaneously, the secondary leakage is easy to cause, and the construction level is high. In addition, the form of the structural drop plate brings difficulty to the manufacture and transportation of the prefabricated floor slab, and does not accord with the development trend of the assembled building.

The non-falling plate and same-layer drainage technology based on the composite floor slab is to realize that the structure of a bathroom area is not falling on the basis of the traditional drainage scheme, and when the composite floor slab layer is cast in situ, a groove pressing mode is adopted, floor drain and branch pipes thereof are laid, and the drainage branch pipes are connected to the vertical pipes to realize the drainage of the floor drain in the shower area. The pressing groove of the floor cast-in-situ layer brings certain difficulty to construction and puts higher requirements on the laying of the gluten of the structural floor. In addition, the technology has a certain limit on the type selection of sanitary appliances, a washbasin and a toilet bowl adopt a plate-up drainage mode, the shielding of the branch pipes is realized by utilizing the cavity, and the drainage branch pipes are connected to the vertical pipes to realize drainage. And the floor drain is required to be an ultrathin side-drain floor drain with a water seal, and has larger limitations on floor drain selection, cost and later maintenance.

In summary, with the continuous development of assembly technology, on the premise of not affecting the assembly rate, there is a need to design a waterproof prefabricated module for building which does not lower the board and drain water on the same layer to realize drainage in wet areas (such as toilets and kitchens).

Referring to fig. 1, fig. 1 is a cross-sectional view of a modular building. In the modularized building, the prefabricated structure of the same floor drainage without lowering the plate, the prefabricated module of the same floor drainage without lowering the plate or the prefabricated system of the same floor drainage without lowering the plate in the bathroom are prefabricated and formed in a factory, and can comprise a building wet area 110 and a building dry area 210, namely the building wet area 110 is used in a kitchen, a bathroom and other areas.

The modular building is prefabricated in a factory, so that the production efficiency can be improved, and the product quality of prefabricated modules can be guaranteed. In addition, the modular building can greatly reduce the types of the prefabricated modules, is favorable for standardization and unification of the prefabricated modules, meets the development requirements of the assembled building, and is favorable for improving the production standard.

The concrete structure of the prefabricated structure for draining water in the same layer without lowering the plate will be described in detail.

Referring to fig. 2 and 3, fig. 2 is a cross-sectional view of a prefabricated structure for draining water at the same layer without lowering the plate; FIG. 3 is a schematic structural view of a prefabricated structure for draining water without lowering the plate on the same layer;

Specifically, the non-drop on-floor drainage pre-form includes a waterproof area 120, the waterproof area 120 may include a flooring assembly 121, and the flooring assembly 121 is configured to be disposed on a rebar truss floor deck. The flooring assembly 121 may include, in order from the bottom layer to the top layer, a secondary waterproof layer 1211, a leveling layer 1213, a primary waterproof layer 1215, an adhesive layer 1217, and a panel layer 1219.

The water-proof region 120 is provided with a drain assembly through which wastewater or sewage is discharged.

Wherein, the drainage assembly may include a primary drainage floor drain 1223 and a secondary drainage floor drain 1225, the secondary drainage floor drain 1225 being disposed at an edge of the secondary waterproof layer 1211 and communicating with the pipe assembly. The primary drain 1223 is disposed at the edge of the primary waterproof layer 1215 near one end of the floor drain and is in communication with the piping assembly, and the upper surface of the primary drain 1223 is flush with the panel layer 1219.

In an alternative embodiment, the primary drain 1223 may be a side drain, conveniently arranged, comprising an interconnected floor drain body with an upper surface flush with the panel layer 1219 and a cross drain tube, the cross drain tube communicating with the pipe assembly at an end remote from the floor drain body.

Optionally, the primary drain 1223 may be an ultrathin side-drain non-water-seal floor drain, which is not only beneficial to reducing the height of the same-layer drain without lowering the plate, but also can save the cost.

Optionally, the secondary waterproof layer 1211 is a steel groove structure, a secondary drainage floor drain 1225 is disposed at a groove bottom position at one end of the steel groove, and the secondary drainage floor drain 1225 is an L-shaped side drainage floor drain.

Specifically, the secondary waterproof layer 1211 may include a bottom steel plate and a peripheral steel plate surrounding the bottom steel plate, and the peripheral steel plate and the bottom steel plate are surrounded to form a waterproof steel groove, and made of stainless steel. The secondary drainage floor drain 1225 may include a floor drain body and a lateral drainage branch pipe connected to each other, where the floor drain body is attached to the waterproof steel tank, and one end of the lateral drainage branch pipe away from the floor drain body is communicated with the pipe assembly. The steel tank structure can be used for secondary water prevention, and the secondary water discharge floor drain 1225 is arranged at the tank bottom of one end of the steel tank and can be used for secondary water discharge, so that accumulated water leaking into the steel tank can be discharged into the waste water vertical pipe 1524 of the pipeline assembly through the secondary water discharge floor drain 1225. That is, the structure also has the functions of secondary water prevention and secondary water drainage on the premise of not lowering the plate and draining water on the same layer.

The leveling layer 1213 is laid over the waterproof steel groove, the primary waterproof layer 1215 is laid over the leveling layer 1213, the adhesive layer 1217 is laid over the primary waterproof layer 1215, and the panel layer 1219 is laid over the adhesive layer 1217.

Specifically, the screed 1213 may include a keel 1221 and a concrete filler, the keel 1221 being fixed to a surface of the secondary waterproof layer 1211, the keel 1221 having a filler cavity as a prefabricated module bottom structural support, the concrete filler being filled in the filler cavity of the keel 1221, the concrete filler being fine stone concrete.

Referring to fig. 4, fig. 4 is a schematic structural view of a keel in the prefabricated structure of the same-layer drainage without lowering the plate.

It will be appreciated that there is a slight difference in the construction of the keel 1221 for the prefabricated module having both the building dry area 210 and the building wet area 110. For example, for a residential bathroom type building wet area 110, the keel 1221 is a hollow frame, and the bottom and the periphery of the keel 1221 are provided with stainless steel plates as a secondary waterproof structure. For the dry area 210 of the living/bedroom type building, a connecting steel sheet 1222 is provided between the hollow frames of the keel 1221 for increasing the keel strength.

Optionally, the waterproof zone 120 further comprises keel steel for isolation from the tubular well zone 150, as in fig. 3, the bottom of the tubing assembly within the tubular well zone 150 being fixedly connected to the keel steel by cast-in floor. After the pipe assembly in the pipe well region 150 is arranged in place and is communicated with the drainage assembly, in order to achieve the integrity of the prefabricated module, the bottom of the pipe assembly is fixedly connected with the floor assembly 121 of the waterproof region 120 in a manner of pouring a floor slab, so that the pipe assembly is integrated, and the pipe assembly is convenient for later transportation.

Note that both the primary and secondary drain 1223, 1225 are located at the same end of the waterproof steel trough.

In order to smoothly drain the waste water from the panel 1219, it is preferable that the panel 1219 should be provided with a slope, and since the panel 1219 is a tile layer with a constant thickness, it is necessary to provide a slope on the leveling layer 1213, and other positions are inclined downward toward the primary drain 1223. Specifically, the concrete filler is discharged to the floor drain 1223 once according to a preset angle slope, and a waterproof civil engineering reverse bank is arranged in the circumferential direction of the waterproof area 120, and is higher than the leveling layer 1213.

Optionally, the upper surface of the screed 1213 has a 1% downward slope toward the primary drain 1223.

Further, referring to fig. 2, the primary waterproof layer 1215 may include a first waterproof coating 1227 and a second waterproof coating 1229, the first waterproof coating 1227 is applied over the leveling layer 1213, the second waterproof coating 1229 is applied over the first waterproof coating 1227, and the adhesive layer 1217 is applied over the second waterproof coating 1229.

That is, the application of the waterproof coating layer of a preset thickness is performed in two times.

Alternatively, the first waterproof coating 1227 and the second waterproof coating 1229 are the same thickness and each use a polymer cement waterproof coating. For example, each time the waterproof coating layer can be coated with a thickness of 2mm, the coating thickness of the waterproof coating layer is reduced on the premise of meeting the waterproof requirement.

Alternatively, the panel layer 1219 may comprise a tile that is adhesively secured to the adhesive layer 1217. Floor drain mounting openings are formed in corresponding positions of the ceramic tiles, and the upper surface of the floor drain body serving as primary drainage is flush with the upper surface of the panel layer 1219, so that waste water of the panel layer 1219 can be smoothly discharged into the waste water riser 1524 through the primary drainage floor drain 1223.

The waterproof prefabricated module for the same-layer drainage building without lowering the plate can realize secondary waterproof and secondary drainage, and effectively avoid water leakage and water seepage. The primary drain 1223 is arranged at the edge of the waterproof area 120 by adopting an ultrathin side-drain non-water-seal floor drain, the secondary drain 1225 is arranged at the edge of the waterproof steel groove by adopting an L-shaped side-drain floor drain, so that the water-drain floor drain is convenient to communicate with a vertical pipe, and the adopted ultrathin side-drain non-water-seal floor drain is common in shape selection and cost saving; it is also possible to effectively realize that the thickness of the flooring assembly 121 in the non-falling co-layer drainage prefabricated module is less than or equal to 70mm.

For example, the secondary waterproof layer 1211 may be formed of a steel plate having a thickness of 10mm, and a steel plate of the bottom and the periphery may be formed into a steel groove structure. The concrete leveling layer 1213 provided above the secondary waterproof steel groove may be set to 40mm, the leveling layer 1213 may be formed by leveling with fine stone concrete, 1% of the slope is toward the floor drain opening position, and the surface is smoothed. The primary waterproof layer 1215 can adopt polymer cement waterproof paint with the thickness of 2 times and 2mm, and the second waterproof coating 1229 positioned below is inverted on the wall and higher than the building finishing surface elevation of the floor by 1800mm, and is inverted on the beam surface when the door is opened, and has the same width as the threshold; the first waterproof coating 1227 located above is inverted on the wall and is 200mm higher than the concrete inverted ridge surface, and is inverted on the beam entrance surface when meeting the door opening, and is as wide as the door threshold, and the waterproof coating is brushed outside the door opening by 300mm. The panel layer 1219 may be applied to the primary waterproof layer 1215 by a special adhesive of 5mm using a tile of 10 mm.

That is, to prevent water leakage and water seepage, secondary water prevention and secondary drainage within a height of 70mm are realized, and installation of the primary and secondary drainage floor drains 1223 and 1225 can be realized within a height of 70 mm.

Further, referring to fig. 3 and 5, fig. 5 is a plan view of the prefabricated module for draining water without lowering the slab.

The prefabricated module for the same-layer drainage without lowering the plate can comprise a drainage pipeline, a drainage collector and the prefabricated structure for the same-layer drainage without lowering the plate.

The prefabricated module for non-falling, same-floor drain may include a primary drain line connected to a primary drain 1223, a secondary drain line connected to a secondary drain 1225, the primary and secondary drain lines passing through a waterproof steel trough in the well 150 and communicating with the inlet of the drain collector 154.
