Description

Technical Field

[0001] This utility model relates to the field of prefabricated kitchens and bathrooms, and particularly to a chassis for prefabricated kitchens and bathrooms. Background Technology

[0002] The kitchen and bathroom are the core functional units in a living environment, characterized by the most concentrated and frequent use. They are also the most complex integrated spaces in a home system—not only must they accommodate multiple interfaces such as decorative surfaces, cabinet storage, and hardware fixtures, but they also need to coordinate the operation of concealed engineering systems such as water supply and drainage, electrical circuits, gas supply, and ventilation. Traditional kitchen and bathroom renovations have long faced the following structural contradictions:

[0003] The contradiction between high performance requirements, high professionalism, and personalization: Indicators such as waterproofing, heat insulation, sound insulation, ventilation, slip resistance, health, environmental protection, energy saving, antibacterial properties, easy cleaning, durability, ergonomics, and applicability to all ages mean that kitchen and bathroom spaces are not just simple decoration design and construction projects. They require personalized customization services throughout the entire life cycle of users, from planning, design, and material selection to construction, daily maintenance, and secondary renovations. General home decoration design capabilities are no longer sufficient.

[0004] The contradiction between the complexity of the process and the low standardization: wet operations such as on-site manual cutting of tiles and pouring of waterproof layers account for more than 60%, and the construction quality depends heavily on the experience of workers;

[0005] The contradiction between long construction period and high frequency of disturbance: Water and electricity renovation, waterproofing test and tiling are carried out in sequence, with an average construction period of 15-25 days, during which dust and noise continuously disturb the neighbors.

[0006] The contradiction between strong functional personalized needs and weak system compatibility: When adding equipment such as electric towel racks, water purifiers, smart toilets, and age-friendly renovations, it is often necessary to dismantle the system again due to mismatched pre-buried pipelines, or even fail to meet the renovation requirements.

[0007] The contradiction between the aging of bricklayers and the high incidence of occupational diseases: For a long time, the construction industry has been the second largest industry in my country with a high incidence of occupational diseases (based on the number of reported cases), second only to the mining industry. The current shortage of bricklayer labor is not sustainable.

[0008] Prefabricated integrated kitchen and bathroom technology is an industrialized solution to address these pain points: by prefabricating waterproof chassis, wall panels, ceilings and other modules in a factory, on-site assembly is simply a matter of "building blocks", which improves construction efficiency by more than 70% and achieves three major breakthroughs: "zero cutting, zero wet work and zero structural damage" on-site. It helps "turn old houses into good houses" and fills the market gap for personalized customization and rapid renovation of kitchen and bathroom spaces in old communities and old houses.

[0009] Among them, the aluminum alloy prefabricated integrated kitchen and bathroom system utilizes the structural strength and precision of the aluminum profile frame to achieve rapid assembly and easy flexible customization of various sizes. It can also integrate various finishes and sandwich structure composite materials. It can be made of various traditional and new finishes such as pre-embedded pipes, adhesive tiles, natural stone, and slabs. It has core advantages such as low carbon and energy saving throughout the process, environmental protection, full product customization, reduced building load, zero leakage, zero hollowing, zero falling off, fast installation, convenient use, and good user experience.

[0010] Currently, most aluminum alloy prefabricated kitchen and bathroom units still use a one-piece chassis for waterproofing. Because there are no seams in the one-piece chassis, the waterproofing effect is relatively good. However, due to the complexity of kitchen and bathroom spaces, customizing a complete chassis for the entire space would be too costly. Therefore, people divide the chassis shape according to the functional areas of the kitchen and bathroom, and achieve the installation of the entire kitchen and bathroom chassis by splicing together chassis from multiple functional areas. At the same time, sealant is applied at the joints between the chassis to minimize leakage problems.

[0011] Meanwhile, after the chassis is assembled from multiple panels, the wall panels are assembled around the outer contour of the chassis. Traditional wall panel assembly methods involve directly connecting the wall panels to the chassis using fixing components, and then sealing the joints.

[0012] However, this design cannot guarantee the flatness of the wall panels when assembled on the same plane. To ensure the flatness of the wall panels, it is necessary to set an assembly positioning reference on the chassis. This positioning reference is generally set around the edge of the chassis, similar to the edge water-retaining strip. This positioning reference is formed by interlocking parts integrally set on the panels. Specifically, after multiple panels are assembled to form the chassis, the interlocking parts on each panel will join together to form an interlocking positioning reference around the edge of the chassis. This positioning reference can serve as both the edge water-retaining strip of the chassis and the subsequent assembly reference for the wall panels.

[0013] The method of forming the interlocking positioning reference leads to problems with sealing the joints at the connection points. Traditionally, these joints are sealed with sealant, but the amount of sealant applied is minimal, posing a risk of leakage over time. Furthermore, since both the chassis joints and the interlocking body joints require sealant application, the chassis assembly process involves numerous steps, impacting construction efficiency.

[0014] Meanwhile, the existing methods for adjusting the flatness of the chassis are all achieved by adjusting the height of the support feet located at the bottom of the chassis. However, during actual installation, interference from the support feet often occurs. Specifically, to ensure stability, the chassis has support feet at its edges and four corners. These support feet generally have a certain height. However, when the chassis is placed on the kitchen or bathroom floor at an angle, if the height of the chassis is not properly matched to the floor, interference between the support feet and the wall can occur, making it difficult to place the chassis. In this case, the installer must adjust the height of the support feet before placement. In extreme installation conditions caused by measurement errors, the support feet can even prevent the chassis from being placed at all. For details on the interference, please refer to [link to relevant documentation]. Figure 24 .

[0015] Based on the above problems, there is an urgent need to design a prefabricated kitchen and bathroom chassis that can improve the overall sealing performance of the chassis and is also easy to construct. Utility Model Content

[0039] This utility model has positive effects: (1) This utility model can effectively solve the problem of waterproofing at the joint of the splicing body, which is conducive to improving the waterproofing of the chassis. At the same time, the first and second joint parts in the sealing component are spliced ​​by interlocking with each other, which can form a tightening state with the splicing of the floor panel, further improving the waterproofing.

[0040] (2) The first and second contouring parts of the sealing component in this utility model can form a natural connection between the splicing parts of two adjacent floor panels at the joint, so that the water-blocking strip is connected completely and naturally, thereby further improving the integrity and aesthetics of the chassis.

[0041] (3) The glue-filling cavity formed by the sealing component in this utility model can be glued through the glue-filling hole after the assembly is completed, which further improves the sealing performance of the splice joint.

[0042] (4) The upper end face of the interlocking body in this utility model is designed as an arc surface so that it is easy to move on the interlocking body when the wall panel is assembled later, because the arc surface can reduce the friction of the wall panel moving on the interlocking body.

[0043] (5) In this utility model, the upper surface of the interlocking body is designed as a groove, and the side wall of the groove adopts an inner low and outer high manner, which allows the groove to form a glue-filling groove. When assembling the wall panel later, the sealing performance of the wall panel and the interlocking body assembly can be improved by filling the groove with glue. At the same time, the inner low and outer high manner of the side wall of the groove allows the water-blocking strip formed by the interlocking body to have a better waterproof effect.

[0044] (6) In this utility model, the sealing component can form a seal on the outside of the chassis by means of the side sealing part, which has the effect of retaining glue and preventing glue from running away.

[0045] (7) In this utility model, the first mating part and the first interlocking part overlap in their extension direction, and the second mating part and the second interlocking part overlap in their extension direction, so that the first mating part of the first sealing member in the sealing assembly naturally connects with the corresponding first interlocking part on the ground panel, and the second mating part of the second sealing member naturally connects with the corresponding second interlocking part on the ground panel; therefore, the first sealing member and the second sealing member can achieve interlocking cooperation when the two adjacent ground panels are assembled by interlocking. This design also allows for further glue application to the assembly points of the ground panel assembly when the sealing assembly is glued, further improving the overall waterproof sealing performance of the chassis.

[0046] (8) This utility model can further improve the glue retention capacity at the splicing point of the assembly component by using the first glue retention groove on the first splicing part and the second glue retention groove on the second splicing part, thereby further improving the waterproof sealing performance of the chassis.

[0047] (9) This utility model, through the first glue filling groove, the second glue filling groove and the overflow groove, can further increase the glue retention capacity and further improve the waterproof sealing of the chassis. At the same time, the overflow groove can also be used as a backup glue filling groove for later leak repair and maintenance.

[0048] (10) This utility model can form the assembly reference of the decorative surface layer on the floor panel through the first limiting flash and the second limiting flash, which greatly improves the standardization of the floor panel and makes the gap of the decorative surface layer uniform and beautiful after the later assembly.

[0049] (11) In this utility model, the support body for supporting the chassis adopts an adjusting screw. Since the adjusting screw is a rod, its edge will not exceed the edge of the chassis, so it is not easy to interfere with the surrounding walls when it is tilted and placed. At the same time, through the adjusting hole, the adjusting end is directly on the upper surface of the chassis, so that the operator can directly stand on the placed chassis to adjust the height, which greatly improves the debugging efficiency.

[0084] (Example 1)

[0085] See Figures 1 to 17 This utility model comprises multiple floor panels 1; each floor panel 1 includes a base plate 11 with edging profiles surrounding it; adjacent floor panels 1 are spliced ​​together by an assembly component 2; the multiple spliced ​​floor panels 1 form a chassis; the edging profiles of the floor panels 1 include splicing side edging profiles 12 and mating side edging profiles 13; the splicing side edging profiles 12 are located on one side of the assembly component 2, and the edging profiles not located on one side of the assembly component 2 are mating side edging profiles 13; the mating side edging profiles 13 are provided with splicing bodies 14; the splicing bodies 14 extend from one end of the mating side edging profile 13 to the other end; each splicing body 14 is distributed along the edge of the chassis formed by splicing multiple floor panels 1 and is mated to form a closed-loop water-blocking strip 15;

[0086] The interlocking parts 14 of two adjacent floor panels 1 are joined together by a sealing component 3 at the joint. The sealing component 3 includes a first sealing element 31 and a second sealing element 32 that are joined together. The first sealing element 31 includes a first insert part 311, a first mating part 312, and a first contouring part 313. The second sealing element 32 includes a second insert part 321, a second mating part 322, and a second contouring part 323. The first sealing element 31 is inserted into the opposite end cavities of the two joined interlocking parts 14. The first insert portion 311 and the second insert portion 321 of the second sealing member 32; when two adjacent floor panels 1 are spliced ​​together, the first mating portion 312 and the second mating portion 322 of the sealing assembly 3 form a mating fit; the outer walls of the first contouring portion 313 and the second contouring portion 323 are naturally connected to the outer walls of their respective splicing bodies 14; after the first mating portion 312 and the second mating portion 322 are mated, the outer walls of the first contouring portion 313 and the second contouring portion 323 are naturally connected, see Figure 2 .

[0087] The first insert portion 311 and the second insert portion 321 match the end cavities of the corresponding insert body 14, and are open in shape. The "open shape" refers to the presence of an opening groove, which allows the first insert portion 311 and the second insert portion 321 to undergo a certain degree of elastic deformation when inserted into the corresponding end cavities. This elastic deformation allows for a tighter fit between the first insert portion 311 and the second insert portion 321 and the corresponding end cavities. See details... Figure 3 .

[0088] One end of the first mating part 312 is disposed on the first plugging part 311, and the other end is a free end; a first mating groove 314 with an upward opening is formed between the first mating part 312 and the first plugging part 311; one end of the second mating part 322 is disposed on the second plugging part 321, and the other end is also a free end; a second mating groove 324 with a downward opening is formed between the second mating part 322 and the second plugging part 321; when two adjacent floor panels 1 are spliced, the first mating part 312 of the first sealing member 31 and the second mating part 322 of the second sealing member 32 form a mating fit through the interlocking of the first mating groove 314 and the second mating groove 324. The first mating part 312 and the second mating part 322 in the sealing assembly 3 are spliced ​​by interlocking, which can form a mutually tightened state as the floor panels 1 are spliced, further improving the waterproofness.

[0089] The second contouring part 323 is provided with a contouring extension part 323-1 extending along the extension direction of the interlocking body 14 and away from the interlocking body 14. When the first mating part 312 and the second mating part 322 are mated together, a glue-filling cavity 33 for glue filling is formed between the first contouring part 313, the second contouring part 323, the contouring extension part 323-1, the first mating part 312 and the second mating part 322, and the outer wall of the contouring extension part 323-1 is naturally connected with the outer walls of the first contouring part 313, the second contouring part 323, and the outer walls of the interlocking bodies 14 on both sides. The contouring extension part 323-1 is provided with a glue-filling hole 34 communicating with the glue-filling cavity 33. After assembly, glue filling of the glue-filling cavity 33 can improve the sealing of the interlocking body joint.

[0090] The upper surface of the interlocking body 14 is arc-shaped; the first contouring part 313 is disposed along the edge of the first inserting part 311; the second contouring part 323 is disposed along the edge of the second inserting part 321. Naturally, the upper surfaces of the first contouring part 313 and the second contouring part 323 (including the upper surface of the contouring extension 323-1) are both arc-shaped. The upper surface of the interlocking body 14 is designed as an arc surface to facilitate movement on the interlocking body during later wall panel assembly, as the arc surface can reduce the friction of the wall panel moving on the interlocking body. See [reference needed]. Figure 10 .

[0091] The first contouring part 313 and the second contouring part 323 of the sealing component 3 can form a natural connection between the interlocking parts 14 of two adjacent floor panels 1 at the joint, so that the water-blocking strip 15 is connected completely and naturally, thereby further improving the integrity and aesthetics of the chassis.

[0092] The first insert portion 311 is also provided with a side sealing portion 315, as can be seen from... Figure 3 and Figure 4 The side sealing part 315 includes a vertical sealing surface 315-1 and a horizontal support surface 315-2; the vertical sealing surface 315-1 and the horizontal support surface 315-2 are integrally formed into an L-shaped side sealing part 315; the vertical sealing surface 315-1 is located on the outer side of the chassis; when the first docking part 312 and the second docking part 322 form a docking fit, the upper end surface of the vertical sealing surface 315-1 is connected with the outer wall of the contour extension part 323-1 located on the outer side, and a sealing fit is formed on the vertical surface of the sealing assembly 3 on the outer side of the chassis; when the first docking part 312 and the second docking part 322 form a docking fit, the horizontal support surface 315-2 abuts against the second plugging part 321, and an overflow cavity 35 is formed between the second plugging part 321, the first docking part 312 and the side sealing part 315.

[0093] See Figures 13 to 17 The assembly component 2 includes a first interlocking body 21 and a second interlocking body 22; one of the two floor panels 1 being assembled has a first interlocking body 21 integrally provided on its edging profile, and the other floor panel 1 has a second interlocking body 22 integrally provided on its edging profile; the first interlocking body 21 includes a first interlocking part 211, the lower end of which is integrally connected to the edging profile, and a first interlocking slot 212 with an upward opening is formed between the first interlocking part 211 and the edging profile; the second interlocking body 22 includes a first interlocking part 211, the lower end of which is integrally connected to the edging profile, and the first interlocking part 211 and the edging profile form a first interlocking slot 212 with an upward opening; the second interlocking body 22 includes a first interlocking part 211, the lower end of which is integrally connected to the edging profile, and the lower end of which is integrally connected to the edging profile. The second interlocking part 221 has its upper end integrally connected to the edging profile it is attached to, forming a downward-facing second interlocking slot 222 between the second interlocking part 221 and the edging profile it is attached to; when two adjacent floor panels 1 are spliced, the corresponding first interlocking part 211 is inserted into the corresponding second interlocking slot 222, and the corresponding second interlocking part 221 is inserted into the corresponding first interlocking slot 212 to form an interlocking assembly; both the first interlocking part 211 and the second interlocking part 221 extend from one end of the edging profile they are attached to to the other end;

[0094] When two adjacent floor panels 1 are spliced ​​together, the projection of the first splicing part 211 and the first docking part 312 at both ends in the extension direction coincides, and the projection of the second splicing part 221 and the second docking part 322 at both ends in the extension direction coincides.

[0095] See Figure 8 and Figure 9The first docking part 312 and the first interlocking part 211 are projected to overlap in their extension direction, and the second docking part 322 and the second interlocking part 221 are projected to overlap in their extension direction, so that the first docking part 312 of the first sealing member 31 in the sealing assembly 3 is naturally connected to the corresponding first interlocking part 211 on the local panel 1, and the second docking part 322 of the second sealing member 32 is naturally connected to the corresponding second interlocking part 221 on the local panel 1; therefore, the first sealing member 31 and the second sealing member 32 can achieve interlocking cooperation when the two adjacent ground panels 1 are assembled by interlocking. This design allows for the application of adhesive in the groove formed by the first mating part 312 and the first interlocking part 211 when splicing two floor panels 1. After the two floor panels 1 are interlocked, adhesive is then injected into the sealing component 3 to achieve a seal at the splice of the first sealing component 31 and the second sealing component 32. It also allows for further application of adhesive to the splice of the assembly component 2 of the floor panels 1, thereby further improving the overall waterproof sealing of the chassis.

[0096] The first interlocking part 211 has a first adhesive retention groove 211-1 extending along the extension direction of the first interlocking part 211 on its end face inside the first interlocking slot 212; the second interlocking part 221 has multiple second adhesive retention grooves 221-1 extending along the extension direction of the second interlocking part 221 on its portion that is in close contact with the first interlocking slot 212. The first adhesive retention groove 211-1 on the first interlocking part 211 and the second adhesive retention groove 221-1 on the second interlocking part 221 can further enhance the adhesive retention capacity at the interlocking points of the assembly components 2, thereby further improving the waterproof sealing of the chassis.

[0097] The second interlocking body 22 also includes a second extension 223 located outside the second interlocking slot 222 and extending from the upper end of the second interlocking part 221 away from the second interlocking slot 222; the second extension 223 extends from one end of the edging profile to the other end; after the two floor panels 1 are spliced, the second extension 223 on one floor panel 1 is in close contact with the edging profile of the other floor panel 1 that has the first interlocking part 211; a first glue filling groove 4 is formed between the second extension 223, the second interlocking part 221 and the edging profile that has the first interlocking part 211;

[0098] A second glue-filling groove 5 is formed between the bottom of the second splicing part 221 and the groove of the first splicing slot 212;

[0099] The first interlocking body 21 also includes a first extension 213 located outside the first interlocking slot 212 and extending from the lower end of the first interlocking part 211 away from the first interlocking slot 212; the first extension 213 extends from one end of the edging profile to the other end; after the two floor panels 1 are spliced, the first extension 213 on one floor panel 1 is closely attached to the edging profile of the other floor panel 1 with the second interlocking part 221; an overflow groove 6 is formed between the first extension 213, the first interlocking part 211 and the edging profile with the second interlocking part 221.

[0100] The first glue-filling groove 4, the second glue-filling groove 5, and the overflow groove 6 further enhance the glue retention capacity and improve the waterproof sealing of the chassis. Meanwhile, the overflow groove 6 can be left unfilled during initial construction, serving as a backup glue-filling groove for later leak repair and maintenance.

[0101] The edging profile with the first splicing part 211 is provided with an upwardly extending first limiting edge 214; the free end of the second extension body 223 is folded upward to form a second limiting edge 224; after the two floor panels 1 are spliced ​​together, the first limiting edge 214 on one floor panel 1 is closely attached to the second limiting edge 224 on the other floor panel 1.

[0102] The floor panel 1 includes a base plate 11 with edging profiles fixed around its perimeter; a decorative surface layer 16 is fixedly provided on the upper surface of the base plate 11.

[0103] The first limiting flange 214 and / or the second limiting flange 224 on the edging profile of the floor panel 1 are used to position and install the decorative surface layer 16. After two adjacent floor panels 1 are spliced ​​together, a splicing seam is formed between the decorative surface layers 16 on the adjacent floor panels 1. The splicing seam is filled with sealant. The first limiting flange 214 and the second limiting flange 224 can form an assembly benchmark for the decorative surface layer 16 on the floor panel 1, which greatly improves the standardization of the floor panel 1. After subsequent assembly, the gaps of the decorative surface layer 16 are uniform and aesthetically pleasing.

[0104] See Figure 11 and Figure 12The assembly 14 includes a mounting body 7 fixedly installed inside; it also includes a support body that cooperates with the mounting body 7 to support the chassis; the mounting body 7 has a threaded through hole; the support body is an adjusting screw 8; the adjusting screw 8 is connected to the threaded through hole; one end of the adjusting screw 8 is a support end 81, and the other end is an adjusting end 82; the support end 81 is located below the chassis and serves the chassis; the adjusting end 82 is used to drive the adjusting screw 8 to rotate and move up and down within the threaded through hole; in the axial projection direction of the adjusting screw 8, the projection of the adjusting screw is completely within the projection of the chassis; the upper end surface of the assembly 14 has an adjusting hole 141 coaxially arranged with the threaded through hole of the mounting body 7; the adjusting hole 141 is used for adjusting tools to act on the adjusting end 82 of the adjusting screw 8 after being inserted. The adjusting end 82 is generally set in an internal hexagonal form, but an external hexagonal form or other forms are also acceptable, as long as the adjusting tool can adjust it.

[0105] The support for the chassis uses an adjusting screw 8. Since the adjusting screw 8 is a single rod, its edge will not extend beyond the edge of the chassis, thus minimizing interference with surrounding walls when it is tilted during placement. Simultaneously, the adjusting hole 141 allows the adjusting end 82 to be directly positioned on the upper surface of the chassis, enabling operators to stand directly on the placed chassis for height adjustments, significantly improving debugging efficiency.

[0106] The assembly and debugging process of this utility model is as follows:

[0107] Based on the kitchen and bathroom space to be constructed, design the quantity and splicing method of the floor panels 1 to be installed. Then manufacture the floor panels 1 as described in this utility model, and pre-install the corresponding sealing components 3 on the floor panels 1.

[0108] During the on-site chassis construction, according to the design plan, a floor panel 1 is first tilted and placed into the kitchen and bathroom space. After the first floor panel 1 is tilted and placed into the kitchen and bathroom space, it is adjusted to the position (usually located on one side edge). Then, sealant is applied to the upward-facing groove formed by the first splicing slot 212 and the first mating part 312. Next, the second floor panel 1 is tilted and placed in the kitchen and bathroom space, and its position is adjusted. Then, it is interlocked with the first floor panel 1.

[0109] Assemble the other floor panels 1 in the above manner to form the chassis.

[0110] Then, the construction workers stood on the chassis and used adjusting tools to level the chassis by adjusting the adjusting end 82 of the adjusting screw 8. Finally, glue was injected through the glue injection hole 34 to achieve a seal at the joint between the first sealing component 31 and the second sealing component 32, further improving the overall sealing performance of the chassis.

[0111] The chassis assembly was finally completed in the manner described above.

[0112] Before placing the floor panel, a shim 9 is placed at the position corresponding to the adjusting screw 8. Then, the support end 81 of the adjusting screw 8 is placed on the shim 9. (See below) Figure 12 .

[0113] (Example 2)

[0114] In this utility model, the first contouring part 313 is provided with a contouring extension part 323-1 extending along the extension direction of the interlocking body 14 and away from the interlocking body; when the first docking part 312 and the second docking part 322 are docked together, a glue-filling cavity 33 for glue filling is formed between the first contouring part 313, the second contouring part 323, the contouring extension part 323-1, the first docking part 313 and the second docking part 322, and the outer wall of the contouring extension part 323-1 is naturally connected with the outer wall of the first contouring part 313, the outer wall of the second contouring part 323 and the outer walls of the interlocking bodies 14 on both sides; the contouring extension part 323-1 is provided with a glue-filling hole 34 communicating with the glue-filling cavity 33.

[0115] Other technical features are the same as in Example 1.

[0116] (Example 3)

[0117] See Figures 18 to 23 In this utility model, the upper end face of the interlocking body 14 is provided with a groove 142; the side wall of the groove 142 located on the outer side of the chassis is higher than the side wall located on the inner side of the chassis; the upper ends of the side walls of the groove 142 located on the inner and outer sides of the chassis are both formed with flanges; the first plugging part 311 and the second plugging part 321 each include a bottom plugging body 3a that is respectively plugged into the bottom cavity of the corresponding interlocking body 14, and a top plugging body 3b that is plugged into the flanged groove 142-1 formed by the flanges of the side walls of the groove 142 located on the inner and outer sides of the chassis.

[0118] The first contouring portion 313 is disposed along the edge of the first insert portion 311; the second contouring portion 323 is disposed along the edge of the second insert portion 321; both the first contouring portion 313 and the second contouring portion 323 form a natural connection with the outer wall of the interlocking body 14 and the side walls of the groove 142 located on the inner and outer sides of the chassis. See also Figure 18 and Figure 19 It can be seen that both the first contouring part 313 and the second contouring part 322 form a groove shape that is higher on the outside and lower on the inside and naturally connects with the groove body 142.

[0119] After the panels 1 are assembled, the grooves 142 of each interlocking body 14 and the first contouring part 313 and the second contouring part 323 of each sealing component 3 are assembled and connected to form a connected glue-filling groove; the glue-filling groove is arranged according to the arrangement of the water-blocking strips 15.

[0120] The bottom surface of the tank 142 is provided with an adhesive inlet groove 142-2 extending along the extension direction of the tank 142; each adhesive inlet groove 142-2 is connected to each glue filling hole 34. Since the adhesive inlet groove 142-2 is located on the interlocking body 14, and there is a certain distance between it and the glue filling hole 4 on the sealing component 3, in this embodiment, the glue filling hole 42 includes a hole body 341 and a guide groove 342 that connects to the hole body 341 and extends to both sides of the interlocking body 14; the guide groove 342 is connected to the corresponding adhesive inlet groove 142-2. The guide groove 342 is distributed on both the first contouring part 313 and the second contouring part 323, see [reference]. Figure 18 , Figure 19 , Figure 21 and Figure 22 .

[0121] The upper surface of the interlocking body 14 is designed as a groove 142, and the side wall of the groove 142 is lower on the inside and higher on the outside, which allows the groove 142 to form a glue-filling groove. When assembling the wall panel later, the sealing between the wall panel and the interlocking body 14 can be improved by filling the groove 142 with glue. At the same time, the side wall of the groove 142, which is lower on the inside and higher on the outside, allows the water-retaining strip 15 formed by the interlocking body 14 to have a better waterproof effect.

[0122] Other technical features are the same as in Example 1.

[0123] The specific method of filling the sealant is as follows: sealant is poured into the tank 142. The sealant will first enter the filling hole 34 along the glue inlet groove 142-2 to fill the filling cavity 33 formed by the sealing component 3, and then fill the tank 142.

[0124] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
