Description

Technical Field

[0001] This invention belongs to the technical field of prefabricated bathroom waterproof structure, specifically relating to a prefabricated bathroom waterproof structure and construction method. Background Technology

[0002] Bathrooms are an indispensable and important functional space in residential and commercial buildings. With social development and improved living standards, people have increasingly higher demands for the comfort and practicality of bathrooms. However, waterproofing has always been a common and serious challenge in traditional bathroom design and construction.

[0003] Currently, traditional bathroom waterproofing structures typically use cement-based materials or polymer waterproof coatings. However, these traditional methods have several shortcomings. First, the application process for cement-based materials is cumbersome and time-consuming, requiring multiple applications and sufficient drying time, increasing the project cycle and cost. Second, cement-based materials are prone to cracking and leakage, affecting the waterproofing effect and service life. While polymer waterproof coatings are simple to apply, their inherent material properties limit their waterproofing performance and durability for long-term use.

[0004] In addition, traditional bathroom waterproofing construction involves complicated procedures, long construction periods, and difficulty in ensuring construction quality, which brings many inconveniences and risks to the construction process.

[0005] Therefore, in view of the above-mentioned problems with traditional bathroom waterproofing structures, there is an urgent need to provide a new type of prefabricated bathroom waterproofing structure and construction method to solve the defects of existing technologies, improve waterproofing effect and construction efficiency, and meet people's ever-increasing demand for bathroom comfort and practicality. Summary of the Invention

[0006] The design objectives of this invention include simplifying the construction process, improving construction efficiency, enhancing waterproofing performance, and ensuring construction quality. By providing a prefabricated bathroom waterproofing structure and construction method, a novel structural design is adopted to reduce construction difficulty, improve waterproofing effect and construction efficiency, thereby enhancing the comfort and practicality of the bathroom.

[0007] This invention discloses a prefabricated bathroom waterproof structure, including a first waterproof board, a second waterproof board, a prefabricated partition wall panel, a decorative base plate, adjustable foot supports, pipe supports, and waterproof strips.

[0008] Prefabricated partition walls consist of a frame panel, a bottom support panel, and inner panels;

[0009] The bottom support partition is located below the first waterproof board, the inner board is located inside the bathroom, and the frame board is tightly attached to the inner board and the bottom support partition.

[0010] A waterproof spacer is provided between the inner panel of the partition wall and the first waterproof panel;

[0011] A pipe support is provided between the second waterproof membrane and the first waterproof membrane. The surface layer of the second waterproof membrane is funnel-shaped. The first and second waterproof membranes are supported by a bottom support partition and adjustable foot supports. The adjustable foot supports are installed on the floor to form an integrated waterproof structure.

[0012] The following improvements are made in this application: the adjustable foot support includes a connecting base plate and a connecting top plate. The connecting base plate is installed on the floor, and the connecting top plate is installed on the second waterproof board. Threaded rods are installed on both the connecting base plate and the connecting top plate. Adjusting screw sleeves are installed on the outer side of the threaded rods to adjust the distance between the connecting base plate and the connecting top plate.

[0013] The following improvements are made in this application: the waterproof spacer is located between the inner panel and the first waterproof panel, and the waterproof spacer is arranged around the perimeter of the wall;

[0014] The decorative base plate is pasted on the waterproof spacer, and the inner plate is tightly attached to the side of the waterproof spacer;

[0015] A dehumidifying plate is installed on the inner panel. There is a space between the bottom of the dehumidifying plate and the decorative base plate. A dehumidifying pipe is embedded in the bottom of the dehumidifying plate. Capillary airflow holes are evenly distributed on the dehumidifying pipe. The top of the dehumidifying pipe is connected to the air outlet of the bathroom heater through a guide cover.

[0016] The following improvements are made in this application: both the decorative base plate and the dehumidification plate are provided with clamping components and sealing components. The clamping component includes a mounting groove and a mounting plate. A spring body and a sliding block are installed in the mounting groove. The mounting plate is installed on the bottom surface of the mounting groove. A connecting body is installed on the sliding block. The connecting body passes through the mounting plate and is connected to the clamping plate. The clamping plate is used to press the waterproof strip close to the inner plate. The sealing component includes two sealing bodies distributed in a figure-eight shape. The bottom of the sealing body gradually deviates from the middle area of ​​the two sealing bodies away from the decorative base plate.

[0017] Both the first waterproof membrane and the inner membrane are provided with sealing grooves, which have a structure that is smaller at the top and larger at the bottom.

[0018] The two sealing bodies squeeze the waterproof spacer to both sides and seal it in the sealing groove.

[0019] The following improvement is made in this application: a movable pipe support is provided at the lower end of the first waterproof membrane;

[0020] The second waterproof membrane layer is funnel-shaped, with a drain outlet at the lowest point of the membrane and a floor drain directly above it.

[0021] The second waterproof membrane has pre-drilled vertical and horizontal pipe holes, which are closed when not in use.

[0022] The following improvements are made in this application: a groove 1 is provided on the inner plate, a groove 2 is provided on the first waterproof plate, and a cylindrical pressure strip is provided on the side of the waterproof spacer facing away from the assembly node of the inner plate and the decorative bottom plate.

[0023] Pressure strips are installed in both groove one and groove two;

[0024] After the inner panel and the first waterproof panel are assembled, the pressure strips at groove one and groove two pull the cylindrical pressure strip towards the side closer to the skeleton panel at an angle of °.

[0025] A construction method for a prefabricated bathroom waterproof structure includes the following steps:

[0026] Step S1, Bottom Construction

[0027] Locate the bathroom area and symmetrically install adjustable foot supports on the floor. Adjust the adjusting screws to make the top of the connecting ceiling plate flush with the design elevation.

[0028] Install the base support partition and the second waterproof membrane on the connecting top plate;

[0029] Step S2, Install the first waterproof membrane

[0030] Several pipe supports are installed on the bottom surface of the first waterproof board. When there are many pipes, they can be placed on the pipe supports and connected to the wall through side outlets.

[0031] The first waterproof membrane is fixed on the bottom support partition and the second waterproof membrane;

[0032] Make a hole in the first waterproof liner and install a floor drain and sewage pipe;

[0033] Step S3, install the decorative base plate

[0034] Pressure strips are installed at the two grooves of the first waterproof membrane. The pressure strips have an arc-shaped structure, and waterproof spacers are temporarily installed on the pressure strips.

[0035] Install clamping and sealing components on the bottom surface of the decorative base plate, and install the decorative base plate on the first waterproof plate. During the installation process, the two sealing bodies squeeze and seal the waterproof spacer in the sealing groove.

[0036] Waterproof grouting material was used to seal the gaps in pipes and drain openings.

[0037] Step S4: Install the frame plate and inner plate.

[0038] Install a pressure strip at a groove in the inner panel. The pressure strip has an arc structure. Install the inner panel on the first waterproof board. After installation, the pressure strips at groove one and groove two pull the cylindrical pressure strip on the outside of the waterproof partition at a 45° angle to the side closer to the frame board. The waterproof partition is pressed tightly against the inner panel and the first waterproof board. Adjust the waterproof partition on the side of the inner panel to be flat. The waterproof partition is arranged around the corner of the bathroom wall. Finally, install the frame board on the outside of the inner panel and the bottom support partition.

[0039] Step S5, Install the dehumidifier plate

[0040] Install a dehumidifier plate on the inner panel, and install a clamping component and a sealing component on the side of the dehumidifier plate opposite to the inner panel. Install the dehumidifier plate on the inner panel. During the installation process, the two sealing bodies squeeze and seal the waterproof spacer in the sealing groove, and connect the top of the dehumidifier pipe on the inner side of the dehumidifier plate to the bathroom heater.

[0041] Compared with existing technologies, the advantages of a prefabricated bathroom waterproofing structure and construction method are:

[0042] This invention employs a first waterproof membrane as a first waterproof layer and a second waterproof membrane as a backup waterproof layer, providing a dual waterproofing mechanism. Even if the first waterproof layer fails, any leakage can still be isolated by the second waterproof membrane.

[0043] This invention employs a prefabricated structure and construction method, which can quickly complete the waterproofing project in the bathroom, shorten the construction cycle, and improve work efficiency.

[0044] The invention features a simple and clear structural design and an easy-to-understand construction method, which reduces the operational difficulty for construction personnel, lowers the error rate during construction, and reduces construction risks.

[0045] The adjustable foot support and movable pipe bracket design of this invention allow for flexible adjustment of the structure's height and position, adapting to different bathroom spaces and floor conditions, thus improving the flexibility and applicability of construction.

[0046] The invention features a reasonable structural design. The installation of waterproof partitions and the treatment with waterproof grouting material ensure a good waterproof effect in the bathroom, effectively preventing leakage problems on the walls and floors and extending the service life of the bathroom.

[0047] The invention also includes a dehumidifying plate on the inner panel. The top of the dehumidifying pipe at the bottom of the dehumidifying plate is connected to the air outlet of the bathroom heater via a guide hood. A portion of the airflow is introduced into the interior of the dehumidifying pipe and dried on the inner side of the waterproof strip through capillary airflow holes. This allows for quick cleaning of water accumulation on the surface of the bottom panel, preventing erosion and mold growth.

[0048] This invention also employs a specific sealing structure to address assembly gaps. The sealing body compresses and seals the waterproof spacer within the sealing groove, resulting in a stable and long-lasting waterproof effect.

[0049] This invention addresses the issue of assembly gaps by first constructing the interior space of the bathroom and then installing the exterior panels. This method effectively solves the problem of assembly gaps and ensures the sealing effect and quality of the assembly gaps. Attached Figure Description

[0055] like Figures 1 to 2 As shown, a prefabricated bathroom waterproof structure includes a first waterproof board 1, a second waterproof board 2, a prefabricated partition wall panel 3, a decorative base plate 4, an adjustable foot support 7, a pipe support 6, and a waterproof strip 5.

[0056] The prefabricated partition wall panel 3 is composed of a frame panel 33, a bottom support partition panel 32, and an inner panel 31;

[0057] The bottom support partition 32 is located below the first waterproof board 1, the inner board 31 is located inside the bathroom, and the frame board 33 is closely attached to the inner board 31 and the bottom support partition 32.

[0058] A waterproof spacer 5 is provided between the inner panel 31 of the partition wall and the first waterproof panel 1;

[0059] A pipe support 6 is provided between the second waterproof membrane 2 and the first waterproof membrane 1. The surface of the second waterproof membrane 2 is funnel-shaped. The first waterproof membrane 1 and the second waterproof membrane 2 are supported by the bottom support partition 32 and the adjustable foot support 7. The adjustable foot support 7 is installed on the floor to form an integrated waterproof structure.

[0060] The waterproofing work on the assembled bathroom structure is completed by adopting waterproof spacer 5 and double-layer waterproof board structure design. Even if the top waterproof board loses its effect, the bottom waterproof board still has a waterproof effect.

[0061] To ensure the horizontal construction of the second waterproofing membrane 2 and thus the horizontal construction of the top structure, the following improvements are made to the above solution: the adjustable support 7 includes a connecting base plate 71 and a connecting top plate 72. The connecting base plate 71 is installed on the floor, and the connecting top plate 72 is installed on the second waterproofing membrane 2. Both the connecting base plate 71 and the connecting top plate 72 are equipped with threaded rods 73. Adjusting sleeves 74 are fitted to the outer sides of the threaded rods 73. The adjusting sleeves 74 are used to adjust the distance between the connecting base plate 71 and the connecting top plate 72. By adjusting the distance between the connecting base plate 71 and the connecting top plate 72 beforehand using the adjusting sleeves 74, the bottom surface of the second waterproofing membrane 2 is ensured to be flat, thereby ensuring the horizontal construction of the top structure.

[0062] After use, a large amount of water will remain on the floor of the bathroom. Due to the presence of water, ventilation alone is not very efficient at evaporating it, which can easily lead to mold and corrosion at the assembly seams, resulting in premature leakage. Based on the above solution, the following improvement is made: the waterproof spacer 5 is located between the inner panel 31 and the first waterproof panel 1, and the waterproof spacer 5 is arranged along the perimeter of the wall.

[0063] The decorative base plate 4 is pasted on the waterproof spacer 5, and the inner plate 31 is tightly attached to the side of the waterproof spacer 5;

[0064] A dehumidifying plate 34 is installed on the inner panel 31. A space is reserved between the bottom of the dehumidifying plate 34 and the decorative base plate 4. A dehumidifying pipe 35 is embedded in the bottom of the dehumidifying plate 34. The dehumidifying pipe 35 is evenly distributed with capillary airflow holes. The top of the dehumidifying pipe 35 is connected to the air outlet of the bathroom heater via a guide hood. By connecting the top of the dehumidifying pipe 35 to the air outlet of the bathroom heater through a pipe, a portion of the airflow can be introduced into the dehumidifying pipe 35 and applied to the inside corner of the waterproof spacer 5 through the capillary airflow holes, thereby quickly cleaning up the water accumulated at the bottom of the bathroom beforehand.

[0065] Since the bottom of the bathroom is the main source of leakage problems in the assembly gaps, and the water accumulation at the bottom causes mold and corrosion problems over a long period of time, ordinary sealing strips and grout sealants cannot effectively solve the problem of long-term leakage. Therefore, the following improvements are made: both the decorative base plate 4 and the dehumidification plate 34 are equipped with clamping components 41 and sealing components 42. The clamping component 41 includes an installation groove 411 and an installation piece 412. A spring body 413 and a sliding block 414 are installed in the installation groove 411. The installation piece 412 is installed on the bottom surface of the installation groove 411. A connecting body 415 is installed on the sliding block 414. The connecting body 415 passes through the installation piece 412 and is connected to the clamping piece 416. The clamping piece 416 is used to press the waterproof spacer 5 near the inner plate 31. The sealing component 42 includes two sealing bodies 4211 distributed in a figure-eight shape. The bottom of the sealing body 4211 gradually deviates from the middle area of ​​the two sealing bodies 4211 away from the decorative base plate 4.

[0066] Both the first waterproof plate 1 and the inner plate 31 are provided with sealing grooves, which have a structure that is smaller at the top and larger at the bottom.

[0067] The two sealing bodies 421 squeeze the waterproof spacer 5 to both sides and seal it in the sealing groove.

[0068] The waterproof spacer 5 is squeezed into the sealing groove by the sealing body 421. As the insertion depth increases, the sealing body 421 will squeeze the waterproof spacer 5 to both sides and stick it to the inner wall of the sealing groove. The sealing body 42 is a thin sheet structure with a certain elastic deformation ability. Finally, the two sides of the waterproof spacer 5 are effectively fixed and a long-term and effective sealing operation is completed.

[0069] Since the waterproof spacer 5 is installed under normal operating conditions, the bonding effect between the waterproof spacer 5 and the inner panel 31, the first waterproof panel 1, and the decorative base plate 4 is not ideal. Therefore, a groove 1 52 is provided on the inner panel 31, a groove 2 53 is provided on the first waterproof panel 1, and a cylindrical pressure strip 51 is provided on the side of the waterproof spacer 5 facing away from the assembly node of the inner panel 31 and the decorative base plate 4.

[0070] Pressure strips 54 are installed at both groove 1 52 and groove 2 53;

[0071] After assembly, the inner plate 31 and the first waterproof plate 1 are pulled at a 45° angle towards the side closer to the skeleton plate 33 by the pressure strips 54 at the groove 1 52 and the groove 2 53.

[0072] The cylindrical pressure strip 51 at the outer corner of the waterproof spacer 5 is pulled outward by the pressure strip 54 and tightly adhered to the surface of both, which can effectively ensure the adhesion. The original inside corner of the waterproof spacer 5 is obtuse, but after installation it can be a right angle or an acute angle close to a right angle. After installation, the inside corner sidewall can adhere to the side of the decorative base plate 4.

[0073] Based on the above scheme, the following improvements are made: the lower end of the first waterproof board 1 is provided with a movable pipe support 6; the surface of the second waterproof board 2 is funnel-shaped, and a drain outlet is provided at the lowest point of the board surface, with a floor drain 11 directly above it; the second waterproof board 2 is provided with a vertical pipe hole 8 and a horizontal pipe hole 8, which are closed when not in use.

[0074] A construction method for a prefabricated bathroom waterproof structure, which effectively solves the problem of poor sealing of assembly gaps by adopting an assembly operation from the inside out, includes the following steps:

[0075] Step S1, Bottom Construction

[0076] Position the bathroom area and install adjustable foot supports 7 symmetrically on the floor. Adjust the adjusting screw sleeves 74 to make the top of the connecting ceiling plate 72 flush with the design elevation.

[0077] Install the bottom support partition 32 and the second waterproof plate 2 on the connecting top plate 72;

[0078] Step S2, Install the first waterproof membrane 1

[0079] Several pipe supports 6 are installed on the bottom surface of the first waterproof board 1. When there are many pipes 9, they can be placed on the pipe supports 6 and connected to the wall through side-mounted connections.

[0080] The first waterproof plate 1 is fixed on the bottom support partition 32 and the second waterproof plate 2;

[0081] Make a hole in the first waterproof membrane 1 and install a floor drain 11 and a sewage pipe 10;

[0082] Step S3, install decorative base plate 4

[0083] A pressure strip 54 is installed at the groove 53 of the first waterproof plate 1. The pressure strip 54 has an arc-shaped structure, and a waterproof spacer 5 is temporarily installed on the pressure strip 54.

[0084] A clamping component 41 and a sealing component 42 are installed on the bottom surface of the decorative base plate 4. Water-stop texture is added to the vertical side wall where the decorative base plate 4 and the waterproof spacer 5 contact. The decorative base plate 4 is installed on the first waterproof plate 1. During the installation process, the two sealing bodies 4211 squeeze and seal the waterproof spacer 5 in the sealing groove.

[0085] Waterproof grouting material was used to seal the gaps in the pipes and floor drains (11 openings);

[0086] Step S4, install the frame plate 33 and the inner plate 31.

[0087] A pressure strip 54 is installed at the groove 52 of the inner panel 31. The pressure strip 54 has an arc structure. The inner panel 31 is installed on the first waterproof board 1. After installation, the pressure strip 54 at the groove 52 and the second groove 53 pulls the cylindrical pressure strip 51 on the outside of the waterproof partition 5 at a 45° angle to the side closer to the skeleton board 33. The waterproof partition 5 is pressed tightly against the inner panel 31 and the first waterproof board 1. The waterproof partition 5 on the side of the inner panel 31 is adjusted to be flat. The waterproof partition 5 is arranged around the corner of the bathroom wall. Finally, the skeleton board 33 is installed on the outside of the inner panel 31 and the bottom support partition 32.

[0088] Step S5, install dehumidifier plate 34

[0089] A dehumidifying plate 34 is installed on the inner plate 31. A clamping member 41 and a sealing member 42 are installed on the side of the dehumidifying plate 34 opposite to the inner plate 31. The dehumidifying plate 34 is installed on the inner plate 31. During the installation process, the two sealing bodies 4211 squeeze and seal the waterproof spacer 5 in the sealing groove, and connect the top of the dehumidifying pipe 35 on the inner side of the dehumidifying plate 34 to the bathroom heater.

[0090] Working principle:

[0091] The working principle of prefabricated bathroom waterproofing structure is mainly based on the following aspects:

[0092] Multi-layered waterproofing design: This structure employs a multi-layered waterproofing design, including a first waterproofing layer, a second waterproofing layer, and waterproof spacers, each playing a crucial role in waterproofing. The first waterproofing layer prevents moisture from the bathroom floor from penetrating to the waterproof layer between the walls and the floor, while the second waterproofing layer acts as another waterproofing layer for the floor, ensuring complete waterproofing of the bathroom floor.

[0093] Sealed connection design: During installation, all components are connected in a sealed manner to ensure seamless joints and prevent moisture penetration. For example, waterproof spacers are used to fill the gaps between partition boards and waterproof boards, and together with sealants and clamping components, the waterproof spacers achieve long-term and effective sealing, ensuring the waterproof effect at this joint.

[0094] Grouting reinforcement: After construction is completed, the waterproof structure will be inspected to ensure there are no leaks at any joints or seams. Then, waterproof grout will be used to reinforce the entire structure, filling any tiny gaps and further enhancing the waterproofing effect.

[0095] Adjustable design: The adjustable foot supports and pipe supports allow the height and position of the structure to be adjusted according to actual conditions, ensuring the stability and integrity of the structure, while improving the flexibility and applicability of construction.

[0096] In summary, this prefabricated bathroom waterproof structure, through multiple methods such as multi-layer waterproof design, sealed connections, grouting reinforcement, and adjustable design, ensures excellent waterproof performance of the bathroom floor and walls, effectively preventing water penetration and leakage problems, and extending the service life of the bathroom.
