Description

Technical Field

[0001] This invention belongs to the field of building interior decoration technology, specifically relating to a waterproof structure suitable for a double-panel base of an integrated bathroom. Background Technology

[0002] With the advancement of industrialized construction, prefabricated integrated bathrooms, with their advantages of dry construction, stable waterproofing performance, and high installation efficiency, are widely used in residential, hotel, and affordable housing applications. The integrated bathroom chassis, as a core component, must simultaneously meet multiple performance requirements, including anti-slip properties, drainage, waterproofing, and ease of installation. Its structural design directly determines the user experience and lifespan of the integrated bathroom.

[0003] In related technologies, most mainstream integrated bathroom chassis on the market are made of SMC composite material in one piece. Their surface features fixed anti-slip protrusions and drainage channels to achieve both anti-slip and drainage functions. The anti-slip structure is often a square or round mosaic protrusion, while the drainage channels are usually straight channels of equal width or grid channels. For large-sized bathroom chassis, to reduce transportation and installation difficulties, a double-jointed structure is typically used. The joints are usually sealed and fixed using a single rubber sealing strip or exposed clips. During installation, leveling is achieved by using elevation control lines and chassis control lines to ensure the chassis is level and the drainage slope is correct.

[0004] In actual installation, bathroom double-panel bases generally have the following problems: the sealing structure at the joints is relatively simple, relying only on a single layer of sealing strip or sealant. After long-term use, the seal is prone to failure due to thermal expansion and contraction or installation deviations, which can lead to leakage in the bathroom. Summary of the Invention

[0005] The purpose of this invention is to provide a waterproof structure suitable for double-panel bases in integrated bathrooms, in order to solve the problem that the sealing structure at the joint of double-panel bases in related technologies is prone to sealing failure due to its simple structure, which in turn leads to leakage in the bathroom.

[0006] The specific technical solution adopted by this invention is as follows:

[0007] A waterproof structure for a double-panel base in a complete bathroom includes: a first base, a second base, a splicing sealing component, a water-blocking and sealing component, and an auxiliary sealing component; The first chassis and the second chassis are spliced ​​together to form an integrated bathroom chassis and laid on the original floor of the building. The splicing sealing component is installed inside the splicing gap between the two chassis, and its four sides are in contact with the wall. The bottom of the first chassis and the second chassis are both equipped with adjustable support brackets, and the surfaces of the two chassis are prefabricated composite ceramic tiles. The outer side of the splicing sealing assembly is fitted with a locking fastener; The water-blocking and sealing assembly is disposed outside the locking and fixing member, and the auxiliary sealing assembly is filled between it and the splicing area of ​​the first chassis and the second chassis.

[0008] In some possible implementations, the splicing sealing assembly is a splicing seam rubber sealing strip that extends along the length of the splicing seam, and its two side walls are respectively squeezed and sealed with the splicing surfaces of the first chassis and the second chassis. The locking fastener is a U-shaped clip, which is connected and engaged at the top of the splicing end of the first chassis and the second chassis, and its inner sidewall presses against the top of the rubber sealing strip; The water-blocking and sealing component is a water-blocking stone, which is laid along the length of the splicing joint, and its bottom is fixed to the tiled surface of the first chassis and the second chassis by adhesive. The water-blocking stone covers the U-shaped clip. The auxiliary sealing assembly includes sealant and grout sealant. The sealant is filled between the water-retaining stone and the U-shaped clip, and between the water-retaining stone and the tile surface. The grout sealant is filled in the outer sealing gap between the water-retaining stone and the tile surface.

[0009] In some possible implementations, both the first chassis and the second chassis are integrally molded from SMC composite material. The ceramic tile surface is bonded to the first chassis and the second chassis in the factory using a special adhesive. Both the first chassis and the second chassis are pre-formed with a drainage slope facing the drain.

[0010] In some possible implementations, the adjustable support bracket includes a support screw and a base, the top of the support screw being fixedly connected to the bottom of the first chassis and the second chassis, the base being supported on the original ground of the building, and the installation height and level of the first chassis and the second chassis being controlled by adjusting the support screw.

[0011] In some possible implementations, the first chassis and the second chassis are joined together to form a bathroom chassis. The surface of the bathroom chassis is divided into a shower area and a water collection area connected thereto. The surface height of the shower area is lower than the surface height of the water collection area, and an inclined water guide surface is provided at the connection between the two.

[0012] In some possible implementations, a floor drain opening connected to a building drainage pipe is provided in the middle of the water collection area, and its surface is inclined along the direction of the floor drain opening.

[0013] In some possible implementations, an annular water channel is formed at the edge of the bathroom base, the annular water channel being connected to the shower area and the water collection area respectively, and the section of the water collection area being inclined along the direction of the drain opening.

[0014] In some possible implementations, a drain cover is detachably provided over the drain opening, the drain cover being used to seal the drain opening.

[0015] In some possible implementations, the drain cover includes a first end and a second end, the bottom surface thickness of the first end is greater than the bottom surface thickness of the second end, and a plurality of drainage holes are provided on the first end near the inclined water guiding surface along the thickness direction.

[0016] In some possible implementations, the second end has drainage gaps on three sides away from the inclined water guiding surface, and the drainage gaps and the drainage holes are all connected to the floor drain.

[0017] The technical effects achieved by this invention are as follows: This invention significantly reduces the transport volume and weight of a large bathroom chassis by splitting it into a first chassis and a second chassis, thus adapting to the requirements of extra-large bathrooms. The entire installation process can be completed on-site using a dry assembly method, effectively improving installation efficiency compared to traditional construction techniques. Simultaneously, a three-layer waterproof structure is employed, consisting of an inner layer sealed with splicing sealing components, a middle layer filled with auxiliary sealing components, and an outer layer for sealing. Combined with the compression sealing of locking fasteners, a fully sealed waterproof system is formed from the inside of the joint between the first and second chassis to the outside, completely solving the problem of seepage that easily occurs at the joint of the two-piece chassis.

[0020] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention.

[0021] like Figure 1 As shown, this invention provides a waterproof structure for a double-panel base suitable for integrated bathrooms. This structure includes a first base 100, a second base 200, a splicing sealing component 300, a locking fastener 800, a water-blocking and sealing component 400, and an auxiliary sealing component 500. Both the first base 100 and the second base 200 can be integrally molded from SMC composite material, forming a symmetrical double-panel structure. After splicing, they can form a complete bathroom base 600. The surfaces of the first base 100 and the second base 200 can be laminated with ceramic tiles in the factory using a special adhesive to form a ceramic tile surface 900. Preferably, both surfaces can also be pre-formed with a 1%-2% drainage slope, with a flush-mounted floor drain installed at the lowest point of the slope to facilitate water drainage.

[0022] A joint sealing component 300 is provided along the length of the joint between the first chassis 100 and the second chassis 200. The joint sealing component 300 can be a long strip of rubber sealing strip. The rubber sealing strip is embedded inside the joint between the two, and its left and right side walls are tightly pressed against the contact end faces of the first chassis 100 and the second chassis 200 to form an inner waterproof sealing structure.

[0023] In this embodiment, the locking fastener 800 can be a U-shaped clip made of stainless steel. The U-shaped clip is evenly spaced across the splicing gap between the first chassis 100 and the second chassis 200 and is locked onto the top of the splicing end of the first chassis 100 and the second chassis 200. The inner walls on both sides of the U-shaped clip abut against the upper surfaces of the two chassis and squeeze the top of the rubber sealing strip, thereby achieving the function of locking and fixing the first chassis 100 and the second chassis 200. This ensures that the width of the splicing gap is uniform and there is no height difference.

[0024] Continue as Figure 1 As shown, the water-blocking and finishing component 400 can be a long strip-shaped splicing node water-blocking stone. The water-blocking stone is laid along the entire length of the splicing gap. The bottom of the water-blocking stone is fixed to the tile surface 900 with special adhesive, and the whole is covered with stainless steel U-shaped clips, thereby realizing the water-blocking treatment and appearance finishing of the splicing node, and can also separate dry areas.

[0025] The auxiliary sealing component 500 may include joint sealant and grout sealant. The sealant fills the gaps between the water-retaining stone and the U-shaped clip, as well as between the water-retaining stone and the tile surface 900, to form a middle layer of waterproofing. The grout sealant fills the outer sealing gap between the water-retaining stone and the tile surface 900, thereby forming an outer layer of waterproof sealing and decorative finishing.

[0026] The following is combined Figure 1 The installation process of the waterproof structure for a double-panel base of a complete bathroom provided by the present invention is described.

[0027] Mark control lines for the first base plate 100 and the second base plate 200 on the original bathroom floor, and determine the splicing position and planar boundary of the first base plate 100 and the second base plate 200. Mark elevation control lines on the bathroom wall to determine the installation height and drainage benchmark of the first base plate 100 and the second base plate 200. Embed the rubber sealing strip into the splicing gap between the two, and then use stainless steel U-shaped clips to cross-lock and engage at the top of the splicing gap, so as to press the rubber sealing strip with the U-shaped clips, completing the splicing of the double base plates and the inner layer sealing. Then use special putty to stick the water-retaining stone above the splicing gap and cover the U-shaped clips. Subsequently, fill the splicing node sealant between the water-retaining stone, the U-shaped clips, and the first base plate 100 and the second base plate 200, and fill the outer edge with grout sealant to complete the middle and outer layer waterproof sealing.

[0028] This invention significantly reduces the transport volume and weight of the large-sized bathroom base 600 by splitting it into a first base 100 and a second base 200, thus adapting it to the requirements of extra-large bathrooms. The entire installation process can be completed on-site using a dry assembly method, effectively improving installation efficiency compared to traditional construction techniques. Simultaneously, a three-layer waterproof structure is employed: an inner layer sealed by a splicing sealing component 300, a middle layer filled by an auxiliary sealing component 500, and an outer layer for sealing. Combined with the compression sealing by locking fasteners 800, a fully sealed waterproof system is formed from the inside of the joint between the first base 100 and the second base 200 to the outside, completely solving the problem of leakage that easily occurs at the joint of the two-piece bases.

[0029] In some embodiments, such as Figure 2As shown, the first chassis 100 and the second chassis 200 are joined to form a bathroom chassis 600. The surface of the bathroom chassis 600 can be divided into a shower area 610 and a water collection area 620. The shower area 610 is the main bathing area, and its surface is lower than that of the water collection area 620. A smooth, sloping water-guiding surface 650 is formed at the connection between the shower area 610 and the water collection area 620, allowing water to flow from the shower area 610 to the water collection area 620. This structural design guides water flow automatically from the shower area 610 to the water collection area 620, thus enabling independent use of the dry area. This not only prevents slipping due to excessive water accumulation in the shower area 610 but also significantly improves the drainage efficiency of the entire bathroom chassis 600.

[0030] Preferably, such as Figure 3 and Figure 4 As shown, a floor drain 630 is provided in the middle of the water collection area 620. The floor drain 630 is connected to the drainage pipe of the building floor, and the entire surface of the water collection area 620 is inclined along the direction of the floor drain 630 to form a specific drainage slope, so that the water in the water collection area 620 can flow to the floor drain 630 more quickly and smoothly.

[0031] In some embodiments, an annular water guide groove 640 is formed at the surface edge of the bathroom base 600. The annular water guide groove 640 is connected to the shower area 610 and the water collection area 620, respectively, and the section of the annular water guide groove 640 located in the water collection area 620 is inclined along the direction of the drain outlet 630. In actual use, part of the water flow in the shower area 610 will flow into the annular water guide groove 640 and be guided into the water collection area 620 through the annular water guide groove 640, thereby realizing the function of rapid, multi-directional and synchronous drainage.

[0032] Continue as Figure 4 , Figure 5 and Figure 6 As shown, the drain in the water collection area 620 is equipped with a detachable drain cover 700, which includes a first end 720 and a second end 730. The first end 720 of the drain cover 700 is close to the inclined water guiding surface 650, and the thickness of the bottom surface of the first end 720 is greater than the thickness of the bottom surface of the second end 730. Furthermore, the first end 720 of the drain cover 700 has several drainage holes 710, and the three sides of the second end 730 each have several drainage notches 740. All drainage holes 710 and drainage notches 740 communicate with the drain opening 630.

[0033] Combination Figure 4As indicated by the arrows, during showering, water in the shower area 610 flows through the annular water guide channel 640 and the inclined water guide surface 650, converging into the water collection area 620. It then quickly drains into the floor drain through the drain hole 710 of the floor drain cover 700 and the drain openings 740 on the three sides. During this process, some hair and other impurities are blocked by the drain hole 710 to prevent them from clogging the building's drainage pipes through the floor drain opening 630, while cleaner water flows smoothly out through the drain openings 740 on the three sides.

[0034] By designing the drain cover 700 with a thickness at one end 720 greater than that at the other end 730, an adaptive flow-guiding structure is adopted. This not only enables multi-directional synchronous drainage but also prevents hair from clogging the building's drainage pipes. Furthermore, the removable design of the drain cover 700 facilitates later cleaning and maintenance, ensuring long-term unobstructed drainage.

[0035] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention are implemented according to conventional methods in the art unless otherwise specified or limited.
