Description

Technical Field

[0001] This invention relates to the field of construction, and more particularly to a connecting profile, a prefabricated kitchen and bathroom wall panel containing the same, and a system thereof. Background Technology

[0002] Prefabricated buildings are constructed using industrialized production methods. Some or all of the building components are prefabricated in a factory, transported to the construction site, and then assembled using reliable connection methods. Compared to traditional construction methods, prefabricated buildings utilize large-scale factory production, ensuring controllable quality and precision, and minimizing material waste. Furthermore, the industrialization of prefabricated construction significantly improves labor productivity, allows for controlled progress, reduces on-site work, and eliminates dust, noise, and wastewater pollution, as well as the large amounts of construction waste generated by secondary renovations. Therefore, prefabricated housing has significant advantages over existing housing.

[0003] Kitchens and bathrooms are prone to dampness due to frequent water use; therefore, waterproofing is crucial for the components used in constructing prefabricated kitchens and bathrooms. However, existing prefabricated kitchens and bathrooms typically use snap-fit ​​connections between adjacent wall panels, which lacks sufficient water tightness. Moisture generated within the kitchen or bathroom can easily seep outwards along the gaps between the wall panels, resulting in poor waterproofing.

[0004] Therefore, the above-mentioned prior art has at least the following technical problems: the connection structure between the prefabricated wall panels in the prior art is not waterproof enough, resulting in poor waterproofing in kitchens and bathrooms. Summary of the Invention

[0005] This application provides a connecting profile, a prefabricated kitchen and bathroom wall panel containing the same, and a system thereof, which solves the technical problem in the prior art where the connection structure between prefabricated wall panels is not waterproof enough, resulting in poor waterproofing of kitchens and bathrooms.

[0006] To solve the above-mentioned technical problems, in a first aspect, embodiments of this application provide a connecting profile, the connecting profile including a body, at least one outer side of the body being provided with a connecting groove for aligning with the connecting groove on another connecting profile and enclosing a pouring cavity, and a flowable adhesive can be injected into the pouring cavity, the cured adhesive can connect the two connecting profiles into one piece.

[0007] Furthermore, the inner surface of the connecting groove is an arc-shaped surface.

[0008] Furthermore, the opening of the connecting groove is narrowed to be narrower than the widest part of the connecting groove body.

[0009] Furthermore, a positioning slot or positioning plug is provided on the outer side of the main body where the groove of the connecting groove is located. The positioning plug can be inserted into the positioning slot, the positioning slot is recessed into the connecting profile, and the positioning plug protrudes from the outer side of the connecting profile.

[0010] Furthermore, the positioning slot is filled with a waterproof adhesive strip, and the positioning plug, which is close to one side of the slot, is inserted into the positioning slot and abuts against the waterproof adhesive strip to form a reverse osmosis structure that prevents water from seeping into the joint between adjacent wall panels.

[0011] Secondly, embodiments of this application also provide a prefabricated kitchen and bathroom wall panel, the kitchen and bathroom wall panel comprising:

[0012] plate body;

[0013] The connecting profile is disposed on at least one outer side of the plate along the width direction, the groove of the connecting groove is located on the outer side of the body along the width direction or on the outer side of the body along the thickness direction, and the body is provided with a connecting structure for connecting with the plate.

[0014] Furthermore, the plate body includes a first plate body located in the middle and a second plate body disposed on the inner and outer sides of the first plate body; the body body includes a first outer side surface disposed with a connecting groove, a second outer side surface and a third outer side surface adjacent to the first outer side surface, and a fourth outer side surface opposite to the first outer side surface.

[0015] The first plate has the same thickness as the connecting profile, and the connecting structure is the fourth outer side surface; the fourth outer side surface is connected to the outer side surface of the first plate along the width direction, and the second plate extends to the second outer side surface and the third outer side surface located on the same side, so that the outer side surface of the second plate along the width direction is flush with the adjacent first outer side surface.

[0016] Furthermore, the plate body includes a first plate body located in the middle and a second plate body disposed on the inner and outer sides of the first plate body; the body body includes a first outer side surface disposed with a connecting groove, a second outer side surface and a third outer side surface adjacent to the first outer side surface, and a fourth outer side surface opposite to the first outer side surface.

[0017] The connecting structure is a first connecting part disposed in the middle of the fourth outer side. The thickness of the first connecting part is thinner than the body, so as to form a first angle with the fourth outer side on both sides respectively. The first connecting part is connected to the first plate, the second plate extends beyond the first plate and extends into the first angle respectively, and the second plate is flush with the adjacent second or third outer side.

[0018] Furthermore, the plate body includes a first plate body located in the middle and a second plate body disposed on the inner and outer sides of the first plate body; the body body includes a first outer side surface disposed with a connecting groove, a second outer side surface and a third outer side surface adjacent to the first outer side surface, and a fourth outer side surface opposite to the first outer side surface.

[0019] The connecting structure includes a second connecting part and a third connecting part. The second connecting part is connected to the second outer side surface and is narrower than the second outer side surface to form a second angle adjacent to the first outer side surface. The height of the second connecting part is lower than the body to form a stepped surface. The third connecting part is connected to the fourth outer side surface and is flush with the third outer side surface. The height of the third connecting part is equal to that of the body.

[0020] The two adjacent sides of the third connecting part are connected to the inner side of the adjacent second plate and the outer side of the first plate, respectively; the second connecting part extends into the first plate, and another second plate extends into the second bend; an end plate is laid on the step surface, and the end plate is flush with the second plate and the connecting profile.

[0021] Thirdly, this application also provides a prefabricated kitchen and bathroom wall panel system, characterized in that the kitchen and bathroom wall panel system includes the prefabricated kitchen and bathroom wall panels, and the connecting grooves between two adjacent kitchen and bathroom wall panels are aligned and enclose a pouring cavity, wherein an adhesive is injected into the pouring cavity, and the cured adhesive connects the two connecting profiles into one piece.

[0022] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0023] (1) By setting a connecting groove on the connecting profile, the connecting profile is used to assemble kitchen and bathroom wall panels. The connecting groove can be aligned with the connecting groove of another kitchen and bathroom wall panel and enclose a pouring cavity. Adhesive can be poured into the pouring cavity between two adjacent kitchen and bathroom wall panels. After the adhesive cures, it connects the two adjacent kitchen and bathroom wall panels into one piece and seals the gap between the two kitchen and bathroom wall panels, thereby improving the waterproofness between the kitchen and bathroom wall panels. This effectively solves the technical problem that the waterproofness of the connection structure between prefabricated wall panels in the prior art is insufficient, resulting in poor waterproofness in the kitchen and bathroom. It achieves the beneficial effects of high connection strength, good air tightness and water tightness.

[0024] (2) A pin is pressed into the top of the connecting groove to squeeze the adhesive and seal the pouring cavity. This not only makes the adhesive more compact, thus improving the connection and waterproofing effect, but also provides a rigid connection between adjacent kitchen and bathroom wall panels, thereby increasing the connection strength.

[0025] (3) The inner groove surface of the connecting groove is set in an arc shape. On the one hand, the arc-shaped inner groove surface increases the contact area with the adhesive, resulting in a better bonding effect. On the other hand, the adhesive is more likely to fill the smooth inner groove, thereby improving the connection strength between adjacent kitchen and bathroom wall panels and improving air tightness and water tightness.

[0026] (4) The inner groove surface of the connecting groove is interference-fitted with the pin. The arc-shaped inner groove surface increases the contact area with the pin and the fit is better, thereby improving the connection strength between adjacent kitchen and bathroom wall panels and increasing waterproofness.

[0027] (5) The narrowing of the groove opening of the connecting groove can reduce adhesive overflow and improve the interlocking effect with the pin.

[0028] (6) A positioning slot or positioning plug is provided on the outer side of the main body where the groove of the connecting groove is located. The positioning slot and positioning plug are connected to facilitate the positioning between adjacent kitchen and bathroom wall panels during assembly.

[0029] (7) The positioning plug is clearance-fitted with the positioning slot to make assembly easier.

[0030] (8) By filling the positioning slot with waterproof adhesive strips and inserting the positioning plug into the positioning slot with the slot opening on one side and abutting against the waterproof adhesive strip, a labyrinth-sealed reverse osmosis structure is formed, which blocks the way for indoor water to seep through the gap between adjacent kitchen and bathroom wall panels, thus improving waterproofing.

[0064] This application provides a connecting profile, a prefabricated kitchen and bathroom wall panel containing the same, and a system thereof, which solves the technical problem in the prior art where the connection structure between prefabricated wall panels is not waterproof enough, resulting in poor waterproofing of kitchens and bathrooms.

[0065] To solve the above-mentioned technical problems, the overall concept of the technical solution provided in this application is as follows: By setting a connecting groove on the connecting profile, the connecting profile is used to assemble kitchen and bathroom wall panels. The connecting groove can be aligned with the connecting groove of another kitchen and bathroom wall panel to form a pouring cavity. Adhesive can be poured into the pouring cavity between two adjacent kitchen and bathroom wall panels. After the adhesive cures, it connects the two adjacent kitchen and bathroom wall panels into one unit and seals the gap between the two kitchen and bathroom wall panels, thereby improving the waterproofness between the kitchen and bathroom wall panels. This effectively solves the technical problem that the connection structure between prefabricated wall panels in the prior art is not waterproof enough, resulting in poor waterproofness in kitchens and bathrooms. It achieves the beneficial effects of high connection strength, good air tightness, and good water tightness.

[0066] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0067] This embodiment provides a connecting profile (including a flat connecting profile 210a and a corner connecting profile 210b) for prefabricated kitchen and bathroom wall panels, which can be used to assemble kitchen and bathroom wall panels (including a flat kitchen and bathroom wall panel 200a and a corner kitchen and bathroom wall panel 200b). These kitchen and bathroom wall panels are used to build prefabricated buildings and are especially suitable for building spaces that require waterproofing due to high water usage, such as kitchens or bathrooms.

[0068] For ease of description, in the embodiments of this application, when the kitchen and bathroom wall panel is used to build the wall of a prefabricated building, the height direction of the prefabricated kitchen and bathroom is the height direction of the kitchen and bathroom wall panel, i.e., the height direction; the width or length of the prefabricated kitchen and bathroom is the width direction of the kitchen and bathroom wall panel, i.e., the width direction; and the indoor / outdoor direction of the prefabricated kitchen and bathroom is the thickness direction of the kitchen and bathroom wall panel, i.e., the thickness direction.

[0069] Figures 1-3 This application shows the structure of the flat-joint profile 210a in one embodiment. Figures 4-5 This application shows the structure of the flat-joint profile 210a in another embodiment. Figures 6-7 This illustrates the structure of the flat-joint profile 210a in yet another embodiment of this application; Figures 8-10 The structure of the corner connection profile 210b in one embodiment of this application is shown. Figures 11-12 The structure of the corner connection profile 210b in another embodiment of this application is shown.

[0070] like Figures 1-12 As shown, both the flat connection profile 210a and the corner connection profile 210b include a body 211. At least one outer side of the body 211 is provided with a connecting groove 212 that is recessed into the body 211, so as to align with the connecting groove 212 on another connection profile and enclose a pouring cavity, thereby allowing adhesive to be injected into the pouring cavity to achieve the connection between the two wall panel connection profiles.

[0071] like Figures 13-15 Or such as Figures 16-17 As shown, the aforementioned flush-joint connecting profile 210a can be used to assemble flush-joint kitchen and bathroom wall panels 200a. The flush-joint kitchen and bathroom wall panel 200a includes a panel 220 and flush-joint connecting profiles 210a symmetrically arranged on both sides of the panel 220 along its width direction. One side of the flush-joint connecting profile 210a is fixedly connected to the panel 220, and the opposite side is provided with a connecting groove 212. The groove opening of the connecting groove 212 extends outward along the width direction of the kitchen and bathroom wall panel for connecting another kitchen and bathroom wall panel. Of course, it is also possible to provide the flush-joint connecting profile 210a on only one side of the panel 220 along the width direction of the kitchen and bathroom wall panel, depending on the specific application scenario, and is not limited here.

[0072] For example Figures 18-20 Or such as Figures 21-22 As shown, the corner connecting profile 210b is used to assemble the corner kitchen and bathroom wall panel 200b. The corner kitchen and bathroom wall panel 200b is used at the corner of a building and is generally connected to the flush-joint kitchen and bathroom wall panel 200a to form a right-angle corner. The corner kitchen and bathroom wall panel 200b includes a body 211 and a corner connecting profile 210b disposed on at least one side of the panel body 220 along the width direction, and the groove of the connecting groove 212 extends forward or backward along the thickness direction of the corner kitchen and bathroom wall panel 200b. Another corner connecting profile 210b, flush-joint connecting profile 210a, or other components may be disposed on the other side of the panel body 220 opposite to the side where the corner connecting profile 210b is disposed, depending on the specific application scenario, and is not limited here.

[0073] like Figures 23-25 As shown in Figures 26-27, 28-29, or 30-31, adhesive is poured into the connecting groove 212 between two adjacent kitchen and bathroom wall panels, which are aligned and abutted together. The adhesive bonds the connecting groove 212. After the adhesive cures, it connects the two adjacent kitchen and bathroom wall panels into one unit and seals the gap between the two kitchen and bathroom wall panels, thereby improving the waterproofness between the kitchen and bathroom wall panels. This effectively solves the technical problem that the connection structure between prefabricated wall panels in the prior art is not waterproof enough, resulting in poor waterproofness in kitchens and bathrooms. It achieves the beneficial effects of high connection strength, good air tightness, and good water tightness.

[0074] Specifically, the adhesive can be any commercially available adhesive, such as polyurethane foam or PUI adhesive (polyurethane-polyimide adhesive). Among these, polyurethane foam (OCF) offers better results. OCF is a product of the cross-combination of aerosol technology and polyurethane foam technology. It is a special polyurethane product that contains polyurethane prepolymer, foaming agent, catalyst, and other components in a pressure-resistant aerosol can. When the material is sprayed from the aerosol can, the foamy polyurethane material rapidly expands and reacts with moisture in the air or the substrate it comes into contact with to form foam. The cured OCF foam has multiple effects such as filling gaps, bonding, sealing, heat insulation, and sound absorption, making it an environmentally friendly, energy-saving, and easy-to-use building material.

[0075] Furthermore, such as Figures 23-25 As shown in 26-27, 28-29 or 30-31, after the adhesive is poured, a pin 230 can be pressed into the top of the connecting groove 212 to squeeze the adhesive and seal the pouring cavity. This not only makes the adhesive more compact, thus improving the connection and waterproofing effect, but also provides a rigid connection between adjacent kitchen and bathroom wall panels, thereby increasing the connection strength.

[0076] Specifically, such as Figures 23-25 As shown in 26-27, 28-29, or 30-31, the pin 230 is interference-fitted with the two connected grooves 212. Figure 32 , 33 As shown, the pin 230 includes two symmetrically arranged connectors 231. The shape of each connector 231 is adapted to the connecting groove 212. The outer surface of the connector 231 is smooth to fit tightly with the connecting groove. The connector 231 is hollow inside to reduce its weight and facilitate transportation.

[0077] Furthermore, the inner surface of the connecting groove 212 is an arc-shaped surface, such as an ellipse. As can be seen from the above description, this embodiment of the application achieves the connection between adjacent kitchen and bathroom wall panels by setting the connecting groove 212 on the connecting profile. Setting the inner surface of the connecting groove 212 to be arc-shaped increases the contact area with the adhesive, resulting in a better bonding effect. On the other hand, the adhesive can more easily fill the smooth inner wall of the connecting groove 212, thereby improving the connection strength between adjacent kitchen and bathroom wall panels and improving air tightness and water tightness.

[0078] In addition, the inner groove surface of the connecting groove 212 is interference-fitted with the pin 230. The arc-shaped inner groove surface increases the contact area with the pin 230 and the fit is better, thereby improving the connection strength between adjacent kitchen and bathroom wall panels and increasing waterproofing.

[0079] Furthermore, the opening of the connecting groove 212 is narrowed to be narrower than the widest part of the groove body, which can reduce adhesive overflow and improve the engagement with the pin.

[0080] In some embodiments, such as Figure 14 , 19 As shown, the aforementioned panel 220 includes a first panel 221 located in the middle, a second panel 222 fixedly laid on the inner and outer sides of the first panel 221 along the thickness direction, and a decorative panel 224 fixedly laid on the inner side of the second panel 222. The first panel 221, the second panel 222 and the decorative panel 224 can be bonded to each other by an adhesive (such as polyurethane foam), or they can be fixed by other mechanical connection methods (such as snap-fit), which is not limited here.

[0081] For example, the first panel 221 can be a honeycomb panel. End plates 225 are provided at both ends of the honeycomb panel along its height direction. The end plates 225 are smoothed at both ends of the honeycomb panel along its height direction to be flush with the end faces of the second panel 222 and the decorative panel 224, thus facilitating stacking and assembly. The honeycomb panel is enclosed between the second panels 222 on the front and rear sides, the end plates 225 at the top and bottom ends, and the connecting profiles on the left and right sides. The honeycomb panel is lightweight and has good load-bearing capacity. Furthermore, the honeycomb panel forms a cavity with the inner and outer second panels 222, providing good sound insulation and heat preservation performance. Therefore, the kitchen and bathroom wall panel described in this embodiment has the beneficial effects of being lightweight, having good load-bearing capacity, and providing good sound insulation and heat preservation.

[0082] Additionally, the second plate 222 can be an inorganic silicon refractory board, the decorative panel 224 can be a ceramic tile, and the end plate 225 can be an aluminum alloy rectangular tube. It should be noted that in other embodiments, the plate 220 can also be of other structures or materials, as long as it is suitable for prefabricated buildings, and is not limited here.

[0083] In this embodiment of the application, the body 211 includes a first outer side surface for which the connecting groove 212 is provided, and also includes a second outer side surface and a third outer side surface adjacent to the first outer side surface, and a fourth outer side surface opposite to the first outer side surface.

[0084] like Figures 13-15 As shown, in one embodiment of this application, the thickness of the flush-joined kitchen and bathroom wall panel 200a is relatively thick, for example, 60mm. In this case, the first panel 221 is relatively thick, and the thickness of the first panel 221 is the same as that of the flush-joined connecting profile 210a. The specific structure of the flush-joined kitchen and bathroom wall panel 200a is as follows:

[0085] The fourth outer side of the flush connection profile 210a forms a connection structure. The fourth outer side is fixed to the outer side of the first plate 221 along the width direction, and the connection groove 212 faces outward of the first plate 221. The second plate 222 and the decorative panel 224 extend to the second outer side and the third outer side of the flush connection profile 210a located on the same side, respectively, so that the outer side of the second plate 222 and the decorative panel 224 along the width direction is flush with the first outer side of the adjacent flush connection profile 210a.

[0086] like Figures 16-17 As shown, in some other embodiments of this application, the thickness of the flush-joined kitchen and bathroom wall panel 200a is relatively thin, for example, 30mm. In this case, the first panel 221 is relatively thin, and the first panel 221 is thinner than the flush-joined connecting profile 210a. The specific structure of the flush-joined kitchen and bathroom wall panel 200a is as follows:

[0087] like Figure 6 , 7 As shown, the connecting structure is a first connecting part 217, which is disposed in the middle of the fourth outer side of the flat connecting profile 210a. The thickness of the first connecting part 217 is the same as the thickness of the first plate 221, so as to connect with the first plate 221. The thickness of the first connecting part 217 is thinner than the body 211, so as to form two first angles with the fourth outer side.

[0088] like Figure 16 , 17 As shown, the first connecting part 217 is connected to the first plate 221, the connecting groove 212 is outward, the second plate 222 extends beyond the first plate 221 and extends into the first angle on the same side, and the second plate 222 is flush with the second outer side or the third outer side on the same side; the decorative panel extends to the body 211, and the outer side of the decorative panel 224 along the width direction is flush with the first outer side on the same side.

[0089] like Figures 18-20 As shown, in one embodiment of this application, the corner kitchen and bathroom wall panel 200b is relatively thick, for example, 60mm. In this case, the first panel 221 is relatively thick, and the first panel 221 is thicker than the main body 211. The specific structure of the corner kitchen and bathroom wall panel 200b is as follows: Figures 8-10 As shown, the corner connection profile 210b also includes a second connection portion 215 and a third connection portion 214 as connection structures, wherein:

[0090] The second connecting portion 215 is connected to the second outer side portion, and the second connecting portion 215 is narrower than the second outer side to form a second bend adjacent to the first outer side; the height of the second connecting portion 215 is lower than that of the body 211 to form a stepped surface. The third connecting portion 214 is connected to the fourth outer side portion and is flush with the third outer side, and the height of the third connecting portion 214 is equal to that of the body 211.

[0091] like Figures 18-20 As shown, one side of the panel 220 along its width direction has a notch for embedding a corner connecting profile 210b. The corner connecting profile 210b is embedded in the notch. The two adjacent sides of the third connecting portion 214 are connected to the inner and outer sides of the adjacent second panel 222 and the outer side of the first panel, respectively. The second connecting portion 215 extends into the first panel 221, and the other second panel 222 and the decorative panel 224 extend into the second corner, with the decorative panel 224 flush with the first outer side. An end plate 225 is laid on the step surface, and the end plate 225 is flush with the second panel 222 and the corner connecting profile 210b.

[0092] like Figures 21-22 As shown, in another embodiment of this application, the corner kitchen and bathroom wall panel 200b is relatively thin, for example, 30mm. In this case, the corner connecting profile 210b is thicker than the first panel 221. The specific structure of the corner kitchen and bathroom wall panel 200b is as follows:

[0093] like Figures 11-12 As shown, the third connecting portion 214 of the corner connecting profile 210b has the same width as the body 211, and the third connecting portion 214 extends to the outer side of the third connecting portion 214 that is flush with the second outer side. Figures 21-22 As shown, one side of the panel 220 along its width direction has a notch for embedding a corner connecting profile 210b. The corner connecting profile 210b is embedded in the notch. The two adjacent sides of the third connecting portion 214 are respectively connected to the inner side of the adjacent second panel 222 and the outer side of the first panel. The second connecting portion 215 extends into the first panel 221, and the other second panel 222 and the decorative panel extend into the second corner. The decorative panel 224 is flush with the first outer side. An end plate 225 is laid on the step surface, and the end plate 225 is flush with the second panel 222 and the corner connecting profile 210b.

[0094] Specifically, the connecting profile and the panel 220 can be bonded and fixed, for example, by polyurethane foam. Of course, the connecting profile and the panel 220 can also be connected by other mechanical structures, such as snap-fit ​​connections, etc., which are not limited here. In one embodiment of this application, the connecting groove 212 is at the same height as the connecting profile and the kitchen / bathroom wall panel. At least one end of the connecting groove 212 is open along its length, thereby facilitating the pouring of adhesive and the insertion of the pin 230. For example, the connecting groove 212 can extend vertically through both ends along its length, with the top end serving as a pouring port and the bottom end communicating with other pouring channels, such as... Figures 1-12 As shown.

[0095] like Figures 1-12As shown, a positioning slot 213 or a positioning plug 216 is provided on the outer side (i.e., the first outer side) of the main body 211 where the groove of the connecting groove 212 is located. The positioning plug 216 can be inserted into the positioning slot 213. The positioning slot 213 is recessed into the wall panel connecting profile, and the positioning plug 216 protrudes from the outer surface of the wall panel connecting profile. The positioning slot 213 and the positioning plug 216 are plugged in to facilitate positioning between adjacent kitchen and bathroom wall panels during assembly.

[0096] For example, in one embodiment of this application, such as Figures 23-27 As shown, the flush-joining connecting profiles 210a on both sides of the flush-joining kitchen and bathroom wall panel 200a are respectively provided with positioning slots 213 and positioning plugs 216. In another embodiment of this application, as Figures 28-31 As shown, the corner connecting profile 210b on one side of the corner kitchen and bathroom wall panel 200b is provided with a positioning slot 213, and the flat connecting profile 210a on the other side is provided with a positioning plug 216. Of course, in other embodiments, the flat connecting profiles 210a on both sides of the flat kitchen and bathroom wall panel 200a may only have a positioning slot 213 or a positioning plug 216 at one end, or both ends of the flat connecting profiles 210a on both sides of the flat kitchen and bathroom wall panel 200a may have a positioning slot 213 or a positioning plug 216, depending on the specific usage scenario. This is not limited here, and the same applies to the corner kitchen and bathroom wall panel 200b.

[0097] Furthermore, such as Figure 25 , 27 As shown in Figure 31, the positioning plug 216 is clearance-fitted with the positioning slot 213 to make assembly easier.

[0098] In another embodiment of this application, such as Figure 25 , 27 As shown in Figure 31, the bottom of the positioning slot 213 is filled with a waterproof adhesive strip. The positioning plug 216 is inserted into the positioning slot 213 along the inner wall of one side of the positioning slot 213 and abuts against the waterproof adhesive strip to form a reverse osmosis structure that prevents water from seeping into the joint between two adjacent wall panels.

[0099] Specifically, water in prefabricated kitchens or prefabricated bathrooms can easily seep out through the gaps between adjacent kitchen and bathroom wall panels. In this embodiment, a waterproof adhesive strip is filled into the positioning slot 213, and the positioning plug 216 is inserted into the positioning slot 213 with its groove tightly against one side and abuts against the waterproof adhesive strip, forming a labyrinth-sealed reverse osmosis structure. This blocks the path of indoor water seeping through the gaps between adjacent kitchen and bathroom wall panels, thus improving waterproofing.

[0100] Furthermore, the positioning slots 213 or positioning plugs 216 are respectively provided on both sides of the opening of the connecting groove 212. The symmetrical arrangement of positioning slots 213 or positioning plugs 216 on both sides of the opening of the connecting groove 212 can further enhance the connection strength and waterproofness, while making the connection more stable.

[0101] When kitchen and bathroom wall panels are thicker, there is more installation space, allowing for a smoother inner surface of the suitable connecting groove 212 and an outer surface of the connector 231 of the pin 230, resulting in better sealing and connection. For example, Figure 32 The displayed pin 230 is adapted to, for example Figures 13-15 The flush-fit kitchen and bathroom wall panel 200a shown or as shown Figures 18-20 The corner kitchen and bathroom wall panel shown is 200b; Figure 33 The displayed pin 230 is adapted to Figures 16-17 The flush-fit kitchen and bathroom wall panel 200a shown or as shown Figures 21-22 The corner kitchen and bathroom wall panel shown is 200b.
