Description

Technical Field

[0001] This invention relates to the field of prefabricated building technology, and more specifically, to a prefabricated waterproof chassis for a bathroom. Background Technology

[0002] Prefabricated bathrooms consist of a basic framework made up of a waterproof base, wall panels, and floor slabs. A finishing layer, such as ceramic tiles, is then applied to the waterproof base, and various functional sanitary wares are added to form independent bathroom units. During manufacturing, prefabricated bathrooms typically use materials such as ceramic tiles, aluminum honeycomb, fiberglass, and PUR, which are pressed and composited in a mold in one step. All components are produced in the factory and assembled on-site, offering advantages such as standardized production, rapid installation, and environmental friendliness and energy efficiency.

[0003] Currently, although prefabricated bathrooms are manufactured in factories, the bathroom floor is required to have a drainage slope according to specifications. However, the current waterproof base uses a standardized fixed style for its edging, which cannot adjust the surface slope. This causes the surface of the finishing layer to be out of plane with the edge of the waterproof base, affecting the flatness of the prefabricated bathroom. If the edge of the waterproof base is cut, it can easily cause the risk of water leakage.

[0004] Therefore, existing technologies still need improvement and development. Summary of the Invention

[0005] The purpose of this invention is to provide a prefabricated waterproof base for bathrooms, in order to solve the technical problems of poor flatness and easy leakage caused by the unevenness between the edge of the waterproof base and the surface of the finishing layer in the prior art.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is: to provide a prefabricated waterproof base plate for a bathroom, comprising:

[0007] The chassis body includes a chassis main board and a decorative layer correspondingly disposed on the upper surface of the chassis main board;

[0008] The chassis surround assembly includes a separately disposed outer panel and an inner panel. The inner panel is movable relative to the outer panel along the axial direction of the chassis body. Both the outer panel and the inner panel are configured as annular rings extending circumferentially along the chassis body. The inner panel is attached to the sidewall of the chassis main board and the trim layer. The upper edge of the inner panel is flush with the upper surface edge of the trim layer. The outer panel is located on the side of the inner panel away from the chassis body and abuts against the inner panel.

[0009] The chassis mainboard, the decorative layer, and the chassis edge assembly are integrally formed by pressing.

[0010] In some embodiments, a limiting transverse edge extending toward the finishing layer is formed on the side wall of the inner panel, the limiting transverse edge dividing the inner panel into an upper edge strip and a lower edge strip, the limiting transverse edge being sandwiched between the chassis main board and the finishing layer, the upper edge strip being attached to the side wall of the finishing layer and together with the limiting transverse edge limiting the finishing layer, and the lower edge strip being attached to the side wall of the chassis main board and together with the limiting transverse edge limiting the chassis main board.

[0011] In some embodiments, the outer panel includes a waterproof frame spaced apart from the inner panel and a base plate disposed at the bottom of the waterproof frame, the base plate extending toward the inner panel and abutting against the lower edge strip, the waterproof frame, the base plate and the inner panel forming an upward-opening mounting groove.

[0012] In some embodiments, all points on the upper surface of the base plate are in the same plane, wherein the upper surface of the base plate is horizontal when the chassis body is placed horizontally.

[0013] In some embodiments, the upper edge strip and / or the lower edge strip are provided with a rubber strip groove that opens into the mounting groove, and a water-stop rubber strip protruding from the upper edge strip and / or the lower edge strip is provided in the rubber strip groove.

[0014] In some embodiments, the outer plate further includes a reinforcing frame that surrounds the bottom plate below.

[0015] In some embodiments, the prefabricated waterproof bathroom chassis further includes a reinforcing bent plate, one end of which is connected to the outer peripheral plate and the other end is embedded in the main chassis plate.

[0016] In some embodiments, the upper surface of the chassis main board is provided with a threshold stone groove, and the chassis edging assembly extends to both sides of the threshold stone groove.

[0017] In some embodiments, the chassis body is provided with a pre-made hole that penetrates the chassis main board and the decorative layer, and a connecting sleeve is embedded in the pre-made hole. The inner wall of the connecting sleeve is provided with a limiting ring in the circumferential direction.

[0018] In some embodiments, the prefabricated waterproof bathroom chassis further includes a chassis prefabrication mold, which prefabricates drainage holes according to the location of the bathroom's drainage outlets. The prefabricated waterproof bathroom chassis is integrally formed by pressing the chassis prefabrication mold and pressing the prefabricated holes according to the drainage holes.

[0019] The beneficial effects of the prefabricated waterproof bathroom chassis provided by the present invention are at least as follows: By separating the outer panel and the inner panel, when the outer panel and the main chassis are placed horizontally in a consistent manner, the inclination of the inner panel can be adjusted along the axial direction of the main chassis, so that the upper edge of the inner panel is flush with the upper surface edge of the finishing layer, making the surface of the prefabricated waterproof bathroom chassis flat, eliminating the need for secondary cutting, reducing the risk of leakage, and making the on-site installation process more convenient.

[0020] The set limiting horizontal edge and top edge strip can effectively limit the surface layer, which not only facilitates manufacturing but also improves the fitting accuracy between components;

[0021] The water-stop strip is squeezed and deformed after being inserted into the mounting groove of the wall panel, thereby sealing the mounting groove, preventing water from entering the mounting groove, and improving waterproofing.

[0022] The reinforced frame is set up to enclose the bottom of the base plate, forming a load-bearing frame that can share the load of the base plate, thereby improving the overall structural strength.

[0023] The added bending reinforcement plate enhances the bonding strength between the outer plate and the main chassis plate, ensuring the integrity of the outer plate and the main chassis plate. Attached Figure Description

[0044] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0045] It should be noted that when a component is referred to as "fixed to" or "set on" another component, it may be directly or indirectly located on that other component. When a component is referred to as "connected to" another component, it may be directly or indirectly connected to that other component. The terms "upper," "lower," "left," "right," "front," "rear," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate orientations or positions based on the accompanying drawings, and are for ease of description only, and should not be construed as limiting the technical solution. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. "A plurality of" means two or more, unless otherwise explicitly defined.

[0046] The following description, in conjunction with the accompanying drawings, describes a prefabricated bathroom waterproof chassis component according to an embodiment of the present invention.

[0047] Please see Figure 1 , Figure 1 The diagram shows a vertical cross-sectional view of the prefabricated bathroom waterproof chassis component when placed horizontally. The prefabricated bathroom waterproof chassis component includes a chassis body 1 and a chassis edging assembly 2. The chassis body 1 includes a chassis main board 11 and a finishing layer 12 correspondingly disposed on the upper surface of the chassis main board 11.

[0048] Continue reading Figure 1 The chassis edge assembly 2 includes a separate outer plate 21 and an inner plate 22. The inner plate 22 can move relative to the outer plate 21 along the axial direction of the chassis body 1. Both the outer plate 21 and the inner plate 22 are constructed as annular rings extending circumferentially along the chassis body 1. The inner plate 22 is attached to the side wall of the chassis main plate 11 and the trim layer 12. The upper edge of the inner plate 22 is flush with the upper surface edge of the trim layer 12. The outer plate 21 is located on the side of the inner plate 22 away from the chassis body 1 and abuts against the inner plate 22. The chassis main plate 11, the trim layer 12 and the chassis edge assembly 2 are integrally formed by pressing.

[0049] See Figure 3 , Figure 3 The prior art chassis edge assembly 6 is shown, including an outer panel 61 and an inner panel 62. The outer panel 61 and the inner panel 62 are fixedly connected and are not separated. That is, the outer panel 61 and the inner panel 62 are integrally formed before the prefabrication of the bathroom waterproof chassis.

[0050] Furthermore, the exemplary manufacturing process for a prefabricated waterproof base plate for a bathroom includes:

[0051] S1. Set up the chassis frame, install the chassis frame on the bottom platform of the pressure equipment, place the chassis edging assembly 2 along the circumferential side wall of the chassis frame, and stack the finishing layer 12 on the upper surface of the bottom frame.

[0052] S2. Adjust the height of the top platform of the pressure equipment so that the distance between the top platform and the bottom platform is equal to the target height of the prefabricated bathroom waterproof chassis currently being produced;

[0053] S3. Using a grouting device, a bonding material is injected into the chassis frame. After the bonding material cures, the chassis main board 11 is formed. At the same time, the decorative layer 12 and the chassis edge assembly 2 are integrally formed with the chassis main board 11 through the bonding effect of the bonding material.

[0054] It is understandable that the main chassis 11 supports the finishing layer 12, which is laid on the main chassis 11 and serves as the bathroom floor. According to regulations, the bathroom floor needs a drainage slope; that is, when the main chassis 1 is placed horizontally, the upper surface of the finishing layer 12 needs to have a certain slope to ensure that accumulated water in the bathroom floor is drained in a timely manner. Furthermore, depending on the actual construction situation, the slope of the finishing layer 12 is not fixed. Figure 1 As shown, the slope of the finish layer is 1.5% at this time, so the height of the inner panel 22 of the chassis edge assembly 2 is set at the standard height.

[0055] Furthermore, in step S1, when using Figure 3 When the existing chassis and existing edging assembly 6 are shown, since the outer panel 61 needs to be placed horizontally in line with the chassis main board 11, and the inner panel 62 and the outer panel 61 are integrally formed, the upper edge of the decorative layer 12 and the upper edge of the inner panel 62 will be at different heights. The upper edge of part of the inner panel 62 will protrude from the upper surface of the decorative layer 12, resulting in an uneven surface of the prefabricated bathroom waterproof chassis. If the inner panel 62 is cut again, the risk of leakage will increase.

[0056] pass Figure 1 The beneficial effects of the prefabricated waterproof bathroom chassis of this application, as shown in the chassis edging assembly 2, are at least as follows: Since the outer edging panel 21 and the inner edging panel 22 are set separately, when the outer edging panel 21 and the chassis main board 11 are placed horizontally in a consistent manner, the inclination of the inner edging panel 22 can be adjusted along the axial direction of the chassis main board 11 so that the upper edge of the inner edging panel 22 is flush with the upper surface edge of the finishing layer 12. After the injected bonding material is cured, the outer edging panel 21, the inner edging panel 22, the chassis main board 11 and the finishing layer 12 are also formed as a single unit. The surface of the prefabricated waterproof bathroom chassis of this application is flat, and no secondary cutting is required, reducing the risk of water leakage and making the on-site installation process more convenient.

[0057] It should be noted that the separate installation of the outer perimeter panel 21 and the inner perimeter panel 22 means that before they are manufactured into prefabricated bathroom waterproof chassis components, such as... Figure 1As shown, the outer perimeter plate 21 and the inner perimeter plate 22 are independent components. After pressing, the outer perimeter plate 21 and the inner perimeter plate 22 are integrated into a single structure through the injection of bonding material. The outer perimeter plate 21 is mainly used to prevent water from the bathroom floor from seeping into the floor slab 8 below the bathroom waterproof chassis. Both the outer perimeter plate 21 and the inner perimeter plate 22 are constructed as rings extending circumferentially along the chassis body 1, meaning: as... Figure 5 As shown, both the outer perimeter plate 21 and the inner perimeter plate 22 are arranged along the circumferential sidewall of the chassis body 1. Although not shown in the attached drawings, the outer perimeter plate 21 can be a prefabricated ring-shaped integral structure or a ring-shaped structure formed by splicing. The inner perimeter plate 22 is preferably a ring-shaped structure formed by splicing, so as to facilitate the adjustment of the inclination of the inner perimeter plate 22 and better match the finishing layer 12.

[0058] In some embodiments, the chassis mainboard 11 is formed by curing a bonding material after it has been left to stand for a period of time. The bonding material can be a material with a certain degree of fluidity and viscosity, such as expanding foam or cement mortar, and can be cured. The finishing layer 12 can be a surface decorative material with a certain strength, such as ceramic tile or marble slab.

[0059] Please see Figure 2 Furthermore, a limiting transverse edge 221 extending toward the decorative layer 12 is formed on the side wall of the inner panel 22. The limiting transverse edge 221 divides the inner panel 22 into an upper edge strip 222 and a lower edge strip 223. The limiting transverse edge 221 is sandwiched between the chassis main board 11 and the decorative layer 12. The upper edge strip 222 is attached to the side wall of the decorative layer 12 and together with the limiting transverse edge 221, limits the decorative layer 12. The lower edge strip 223 is attached to the side wall of the chassis main board 11 and together with the limiting transverse edge 221, limits the chassis main board 11.

[0060] During the assembly and fabrication of the prefabricated bathroom waterproof chassis, the lower surface of the finishing layer 12 is attached to the limiting transverse edge 221, and the inner cladding plate 22 is adjusted so that the upper edge strip 222 is attached to the side wall of the finishing layer 12. This completes the assembly of the finishing layer 12. Subsequently, bonding materials are poured in to form the prefabricated bathroom waterproof chassis of this application. The limiting transverse edge 221 and upper edge strip 222 effectively limit the finishing layer 12, facilitating fabrication while improving the fitting accuracy between components.

[0061] Of course, for ease of construction, the height of the upper edge strip 222 is the same as the thickness of the finishing layer 12, ensuring that after the finishing layer 12 is placed, the upper edge of the upper edge strip 222 is flush with the surface edge of the finishing layer 12, without the need for subsequent adjustments.

[0062] It is understood that the function of the limiting transverse edge 221 is to limit the surface layer 12. Therefore, the limiting transverse edge 221 can be a strip-shaped transverse edge that extends continuously along the circumference of the chassis body 1 on the side wall of the inner enclosure 22. Of course, it can also be transverse edge protrusions that are spaced apart along the circumference of the chassis body 1 on the side wall of the inner enclosure 22. These do not deviate from the principle of this application, and therefore all fall within the protection scope of this application.

[0063] Please see Figure 2 Furthermore, the outer panel 21 includes a waterproof frame 211 spaced apart from the inner panel 22 and a bottom plate 212 disposed at the bottom of the waterproof frame 211. The bottom plate 212 extends toward the inner panel 22 and abuts against the lower edge strip 223. The waterproof frame 211, the bottom plate 212 and the inner panel 22 constitute an upward-opening mounting groove 3. The mounting groove 3 provides an installation base for the subsequently installed bathroom wall panel 7. The wall panel 7 is installed in the mounting groove 3 by insertion.

[0064] The outer perimeter plate 21 is arranged around the outer ring of the inner perimeter plate 22 along the circumference of the chassis body 1. The area between the outer perimeter plate 21 and the inner perimeter plate 22 is used to place the wall panel 7, such as... Figure 7 As shown, the bottom of the wall panel 7 is inserted into the mounting groove 3, which consists of a waterproof frame 211, a base plate 212, and an inner cladding plate 22, making on-site installation more convenient and precise. To ensure the sealing of the wall panel 7 after installation and reduce the risk of water leakage after the wall panel 7 is installed in the mounting groove 3, the waterproof frame 211 and the base plate 212 are constructed as a single piece of equal length. This single-piece structure also improves the structural strength of the outer cladding plate 21.

[0065] Please see Figure 1 and Figure 2 In some embodiments, all points on the upper surface of the base plate 212 are on the same plane, that is, the base plate 212 is constructed as a flat plate, such as... Figure 7 As shown, when the wall panel 7 is inserted into the mounting groove 3, the flat panel and the bottom surface of the wall panel 7 fit together more easily and with a high degree of fit, which helps to reduce the risk of water leakage.

[0066] Furthermore, when the main body 1 of the chassis is placed horizontally, the upper surface of the base plate 212 must also be horizontal. During the installation of the prefabricated bathroom waterproof chassis on the construction site, the main body 1 of the chassis will be placed horizontally, and the wall panels 7 generally adopt a square board structure. Therefore, the upper surface of the base plate 212 needs to be horizontal to provide a stable and close fit for the wall panels 7 during installation, ensuring that the upper and lower ends of the wall panels 7 are flat, and also providing a foundation for the subsequent installation of the suspended ceiling. If the upper surface of the base plate 212 is tilted, a gap will appear between the wall panels 7 and the base plate 212, increasing the risk of leakage. Alternatively, the wall panels 7 may also tilt after installation, deviating from the preset position and reducing the accuracy of installation.

[0067] Given the above, since the outer perimeter panel 21 and the inner perimeter panel 22 of this application are separately configured, the inclination of the inner perimeter panel 22 can be adjusted arbitrarily during the prefabrication of the waterproof chassis while maintaining the level of the bottom plate 212 of the outer perimeter panel 21. After adjusting the mating angle between the inner perimeter panel 22 and the finishing layer 12, they are integrally formed by injecting bonding material. However, when using... Figure 3 In the case of the integrated outer panel 61 and inner panel 62 shown, if the mating angle between the inner panel 62 and the finishing layer 12 is adjusted so that the upper edge of the inner panel 62 is flush with the upper surface edge of the finishing layer 12, the outer panel 61 will also tilt, causing the bottom surface of the mounting groove 3 to be uneven. This makes the prefabricated bathroom waterproof chassis inconvenient to install and increases the risk of leakage. Therefore, the separate outer panel 21 and inner panel 22 make the bathroom waterproof chassis prefabricated component of this application more adjustable, have a wider range of adaptability, and improve the convenience and sealing of on-site installation.

[0068] Please see Figure 2 Furthermore, to improve the water-proof performance of the mounting groove 3, a rubber strip groove 224 opening into the mounting groove 3 is provided on the upper edge strip 222 and / or the lower edge strip 223. A water-stop rubber strip 225 protruding from the upper edge strip 222 and / or the lower edge strip 223 is provided within the rubber strip groove 224. If a gap appears between the wall panel 7 and the mounting groove 3 after the wall panel 7 is inserted into the mounting groove 3, water from the bathroom floor can easily seep through the gap into the mounting groove 3 and the floor slab 8 below the prefabricated bathroom waterproof base. The rubber strip groove 224 provides installation space for the water-stop rubber strip 225. Figure 7 As shown, the waterproofing strip 225 is squeezed and deformed after being inserted into the mounting groove 3 on the wall panel 7, thereby sealing the mounting groove 3, preventing water from entering the mounting groove 3, and improving waterproofing.

[0069] In some implementations, alternatively, such as Figure 2 As shown, the adhesive strip groove 224 is provided on the upper edge strip 222, and the adhesive strip groove 224 is an arc-shaped groove. The water-stop adhesive strip 225 is embedded in the adhesive strip groove 224 and protrudes from the upper edge strip 222. Of course, the adhesive strip groove 224 and the water-stop adhesive strip 225 are provided to improve waterproofing. Therefore, the adhesive strip groove 224 can also be provided on the lower edge strip 223, and the water-stop adhesive strip 225 is correspondingly protruding from the lower edge strip 223.

[0070] Furthermore, to further improve waterproofing, a rubber strip groove 224 can be provided on both the upper edge strip 222 and the lower edge strip 223, and a corresponding water-stopping rubber strip 225 can be provided. This application does not limit the number of rubber strip grooves 224 provided; one or more can be provided. These do not deviate from the principle of this application and therefore all fall within the protection scope of this application.

[0071] Optionally, the waterproofing strip 225 is a rubber strip.

[0072] Please see Figure 1 and Figure 2 Furthermore, to enhance the structural strength of the chassis edging assembly 2 and the prefabricated bathroom waterproof chassis, the outer panel 21 also includes a reinforcing frame 213, which is arranged around the bottom of the base plate 212. Since the mounting groove 3 of the prefabricated bathroom waterproof chassis needs to support the wall panel 7, the base plate 212 plays a primary load-bearing role. The reinforcing frame 213, arranged around the bottom of the base plate 212, forms a load-bearing frame, which can share the load on the base plate 212, thereby improving the overall structural strength.

[0073] Optional, such as Figure 2 As shown, the reinforcing frame 213 is integrally formed with the base plate 212, forming a hollow box-like structure below the base plate 212. This improves structural strength while reducing structural weight and material consumption. Of course, to share the load on the base plate 212 and improve structural strength, the reinforcing frame 213 can also be set as a solid block structure.

[0074] Please see Figure 2 Furthermore, to improve the integrity of the outer panel 21 and the main chassis 11, the prefabricated waterproof bathroom chassis also includes a reinforcing bent plate 214, one end of which is connected to the outer panel 21 and the other end is embedded in the main chassis 11.

[0075] When prefabricating the waterproof bathroom chassis of this application, after the outer panel 21 is placed in a predetermined position, a bonding material is poured in. As the bonding material cures, the chassis main board 11 is formed, and simultaneously, the outer panel 21 is integrally formed with the chassis main board 11 through the adhesive effect of the bonding material. Although the outer panel 21 and the chassis main board 11 can be integrally formed through adhesion, with the addition of the reinforcing bending plate 214, the reinforcing bending plate 214 can be embedded into the cured chassis main board 11 during the curing process, forming an integral structure. Compared to the integral structure formed by adhesion, the bonding strength between the outer panel 21 and the chassis main board 11 is higher, ensuring the integrity of the outer panel 21 and the chassis main board 11.

[0076] In some implementations, such as Figure 2 As shown, one end of the reinforcing bent plate 214 is a flat plate and is connected to the reinforcing frame 213 of the outer plate 21. This part of the reinforcing bent plate 214 is flush with the bottom surface of the reinforcing frame 213 to make the bottom of the bathroom waterproof chassis prefabricated component flat, which facilitates the subsequent installation with the floor slab 8. The other end of the reinforcing bent plate 214 is constructed as a bent plate and is embedded in the chassis main plate 11. The structure of the bent plate is less likely to detach when embedded in the chassis main plate 11, which improves the bonding strength between the outer plate 21 and the chassis main plate 11.

[0077] Optionally, since the waterproof frame 211, base plate 212, and reinforcing frame 213 are all constructed as a single unit, to improve the bonding strength between the outer plate 21 and the main chassis 11, the reinforcing bent plate 214 can also be connected to the base plate 212 of the outer plate 21, or to the waterproof frame 211 of the outer plate 21. Furthermore, the reinforcing bent plate 214 is integrally formed with the outer plate 21.

[0078] In some implementations, please refer to Figure 5 This application provides a threshold groove 4 along the edge of the upper surface of the main chassis 11, and the chassis edging assembly 2 extends to both sides of the threshold groove 4. Understandably, when assembling prefabricated bathroom waterproof chassis, it is necessary to ensure that the prefabricated bathroom waterproof chassis aligns with the bathroom threshold. Existing prefabricated bathroom waterproof chassis, due to issues such as the lack of a threshold groove 4 or poor assembly fit, require secondary cutting of the chassis edging assembly 2, affecting waterproofing.

[0079] By setting a threshold groove 4, the chassis edge component 2 ends in the threshold groove 4 area during the prefabrication process. That is, the bathroom waterproof chassis prefabricated part of this application does not have a chassis edge component 2 in the threshold groove 4 area. No secondary cutting is required in the subsequent assembly process, the installation and positioning are accurate, and the waterproof performance is improved.

[0080] Example: The steps of forming the threshold stone groove 4 during the prefabrication process in this application include:

[0081] In step S1, a chassis frame is set up and installed on the bottom platform of the pressure equipment. A threshold stone mold is placed at a prefabricated position on the side wall of the chassis frame. The chassis edging assembly 2 is placed along the circumferential side wall of the chassis frame and abuts against both sides of the threshold stone mold. The finishing layer 12 is stacked on the upper surface of the bottom frame.

[0082] Continue with steps S2 and S3.

[0083] Please see Figure 1 and Figure 4 Furthermore, the chassis body 1 is provided with a pre-drilled hole 13 penetrating the chassis main plate 11 and the decorative layer 12. A connecting sleeve 14 is embedded in the pre-drilled hole 13, and a limiting ring 15 is provided circumferentially on the inner wall of the connecting sleeve 14. During on-site construction and assembly, the chassis body 1 is placed above the bathroom floor slab 8. To ensure drainage, a pre-drilled hole 13 is provided on the chassis body 1, and the connecting sleeve 14 is pre-embedded in the pre-drilled hole 13 and connects with the connecting sleeve of the floor slab 8. During the connection process, the connecting sleeve abuts against the limiting ring 15 of the connecting sleeve 14. The limiting ring 15 limits the connection of the connecting sleeve, ensuring the convenience and accuracy of the connection.

[0084] Optionally, the limiting ring 15 is an annular protrusion extending circumferentially along the inner wall of the connecting sleeve 14. The limiting ring 15 and the connecting sleeve 14 are integrally formed by pressing. Of course, the limiting ring 15 can also be fixedly connected to the connecting sleeve 14 by snap-fit ​​or welding.

[0085] For example, the steps of forming the pre-formed hole 13 during the prefabrication process in this application include:

[0086] In step S1, a chassis frame is set up and installed on the bottom platform of the pressure equipment. A pre-made hole mold is placed at the pre-made position of the chassis frame. The decorative layer 12 is stacked on the upper surface of the bottom frame, and the pre-made hole mold is aligned and inserted into the pre-made hole 13 of the decorative layer 12.

[0087] Continue with steps S2 and S3.

[0088] Please see Figure 6 Furthermore, the prefabricated waterproof base of the bathroom also includes a base prefabrication mold 5. The base prefabrication mold 5 is prefabricated with drainage holes 51 according to the drainage outlet location of the bathroom. The prefabricated waterproof base of the bathroom is integrally formed by pressing the base prefabrication mold 5 and prefabricating holes 13 according to the drainage holes 51.

[0089] To ensure the accurate dimensions and positioning of the prefabricated waterproof bathroom chassis components and water pipe parts of this application, a prefabricated chassis mold 5 is provided. The prefabricated chassis mold 5 matches the actual dimensions of the assembled bathroom and forms drainage holes 51 according to the drainage outlet locations of the bathroom. When prefabricating the prefabricated waterproof bathroom chassis components of this application, it provides precise positioning of dimensions and hole positions, ensuring more convenient installation and accurate hole matching during on-site assembly. This avoids mismatch between the size and / or position of the drainage holes 51 and the prefabricated holes 13, and largely avoids secondary sealing.

[0090] Furthermore, the precast chassis mold 5 and the bathroom floor slab mold 8 are made of the same mold and have the same specifications and dimensions. During assembly, if... Figure 7 As shown, this ensures that the prefabricated waterproof base of the bathroom in this application is precisely assembled with the bathroom floor slab 8, making installation convenient and accurate.

[0091] For example, the prefabrication process of the prefabricated bathroom waterproof chassis component of this application includes:

[0092] S1. According to the size specifications of the chassis prefabrication mold 5, the chassis frame and the decorative layer 12 are made. The chassis frame is set up and a threshold stone prefabrication groove is formed on the chassis frame. The chassis frame is installed on the bottom platform of the pressure equipment. The threshold stone mold is placed at the threshold stone prefabrication groove position on the side wall of the chassis frame. The chassis edging assembly 2 is placed along the circumferential side wall of the chassis frame and the chassis edging assembly 2 abuts against both sides of the threshold stone mold.

[0093] According to the position of the drainage hole 51 of the chassis prefabrication mold 5, a prefabricated hole 13 is formed on the decorative layer 12, and the prefabricated hole mold is placed at the prefabrication position of the chassis frame. The decorative layer 12 is stacked on the upper surface of the bottom frame, and the prefabricated hole mold is aligned and inserted into the prefabricated hole 13 of the decorative layer 12, while keeping the edge of the inner circumference plate 22 of the chassis circumference assembly 2 flush with the surface of the decorative layer 12.

[0094] S2. Adjust the height of the top platform of the pressure equipment so that the distance between the top platform and the bottom platform is equal to the target height of the prefabricated bathroom waterproof chassis currently being produced;

[0095] S3. Using a pouring device, a bonding material is poured into the chassis frame. After the bonding material cures, the chassis main board 11 is formed. At the same time, the decorative layer 12 and the chassis peripheral components are integrally formed with the chassis main board 11 through the bonding effect of the bonding material.

[0096] S4. Demold the threshold stone mold and the pre-made hole mold.

[0097] The prefabrication process, through the precise positioning of the prefabrication mold 5, ensures the accurate positioning of the holes and dimensions of the prefabricated bathroom waterproof chassis components of this application, making on-site assembly more convenient, avoiding secondary sealing, and significantly reducing costs; at the same time, the prefabrication process of the prefabricated bathroom waterproof chassis components of this application is convenient and precise, reducing the risk of water leakage.
