Description

Technical Field

[0001] This utility model relates to the field of building decoration, and in particular to prefabricated kitchens and bathrooms. Background Technology

[0002] Prefabricated kitchen and bathroom products have undergone years of technological iteration. The first generation of products was FRP (fiberglass reinforced plastic) integrated bathrooms, which were produced by hand lay-up. This method had drawbacks such as long production cycles, unstable quality, and short service life. In addition, it was not compatible with mainstream finishing materials such as ceramic tiles and marble, and was no longer suitable for the needs of modern industrial manufacturing.

[0003] Second-generation products such as SMC (sheet molding compound) and VCM (color steel composite system), while showing progress in industrial production, are still heavily constrained by mold design, making flexible customization difficult. On-site installation is complex, and pipelines cannot be effectively pre-embedded and integrated. Furthermore, the materials themselves are not alkali-resistant and produce a hollow feel when tapped, failing to meet the quality and customization requirements of the high-end residential and mid-to-high-end hotel markets. Particularly in the wall panel assembly stage, traditional interlocking structures are prone to creating an "air cushion effect" due to air obstruction, leading to uneven assembly and loose connections, severely impacting installation efficiency and quality.

[0004] Currently, the industry has entered the third-generation product stage, centered on aluminum alloy frame structures. The third-generation aluminum alloy prefabricated integrated kitchen and bathroom system fully utilizes the structural strength, high precision, and ease of processing of aluminum profiles, enabling rapid assembly and flexible customization. It is compatible with various finishing materials such as ceramic tiles, natural stone, and sintered stone, and allows for pre-embedded pipeline integration. Its core advantages lie in its low-carbon and environmentally friendly process, fully customizable products, reduced building load, and pursuit of high standards of "zero leakage, zero hollow areas, and zero detachment."

[0005] However, even with third-generation products, the following problems still exist during actual installation: I. The interlocking and fitting of wall panels with the chassis and between wall panels still faces challenges: When the interlocking slots and interlocking bodies mate, the trapped air cannot be expelled in time, creating air cushion resistance. This makes it difficult for the wall panels to slide, requires more effort to install, and may even affect the tightness of the final joints. This problem restricts further improvements in installation efficiency and also affects the installation experience.

[0006] 2. Traditional external corner construction and internal corner construction are assembled by two wall panels with splicing beveled edge profiles. Although this process avoids on-site cutting of the wall panel body, it still has the following structural defects: (1) Lack of spatial tolerance: The building base wall surface generally has vertical deviation (±3mm / 2m) and local unevenness, while the rigid geometric structure of the edge profile requires strict spatial matching. When there is a difference between the actual installation space and the design size: the tenon and mortise of the two sets of profiles at the external corner will cause mechanical interference due to displacement deviation (such as the male tenon hitting the female groove sidewall). The cumulative error of the profile end in the three-dimensional direction will cause the splicing resistance to surge; (2) Dynamic stress concentration phenomenon: the forced correction operation (such as hammering, lever pressing) taken to eliminate interference during the installation process will produce two types of problems: local deformation and plastic deformation at the thin wall of the profile; (3) Stress freezing: the residual assembly stress makes the external corner a structural weak point, and the joint expands after long-term use; (4) Operation obstacles in narrow space: the external corner of the kitchen and bathroom is often located in the dense pipe area (such as the corner of the drainage riser), and the installation efficiency needs to be improved; (5) Loss of control of joint uniformity: since the decorative surface (such as tiles) is prefabricated on the wall panel, if adaptive adjustments are made during the assembly of the external corner, it will often lead to the joint at the external corner being inconsistent with the plane joint of the wall panel. Meanwhile, the lower joint at the external corner will expand due to gravity sinking or stress release, resulting in a visually deformed gap band, which violates the refined requirements of high-end prefabricated decoration.

[0007] Thirdly, most aluminum alloy prefabricated kitchen and bathroom units currently use a one-piece chassis for waterproofing. Since 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, the chassis shape is divided according to the functional areas of the kitchen and bathroom, and the chassis for the entire space is installed by splicing together multiple functional area chassis. At the same time, sealant is applied at the joints between the chassis to minimize leakage.

[0008] 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.

[0009] 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.

[0010] 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.

[0011] 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 44 .

[0012] Based on the above problems, there is an urgent need to design a third-generation prefabricated kitchen and bathroom product that can effectively improve or solve the above technical problems. Utility Model Content

[0041] This utility model has positive effects: (1) This utility model realizes the upper and lower splicing of wall panels through standardized connecting components. The structure is simple and the positioning is accurate. It is also conducive to realizing fast and smooth vertical assembly operations, which reflects the advantages of efficient assembly. At the same time, the wall panels are divided in the upper and lower directions, which is conducive to elevator transportation.

Its primary function is to ensure that air can be smoothly discharged when the upper and lower plates are inserted, so that the splicing action is smooth and labor-saving, and avoids the problem of loose splicing caused by air blockage.

[0044] (4) The cross-section of the first splicing body and the first splicing slot in this utility model adopts an arc-shaped design, which has excellent guiding properties and can guide the wall panel to slide smoothly into the predetermined position, reducing installation resistance.

[0045] (5) The cross-section of the second splicing body and the second splicing slot in this utility model adopts an arc-shaped design, which makes it easier for the upper and lower plates to be inserted and slid when they are joined, thus achieving smooth vertical splicing.

[0046] (6) In this utility model, the first exhaust groove adopts a distribution design of middle air groove and two side air grooves, forming an efficient three-dimensional exhaust network, ensuring that air can be quickly discharged at each stage of the assembly process, minimizing sliding friction and ensuring smooth installation.

[0047] (7) The second exhaust groove of this utility model adopts a similar middle and side exhaust groove design, which provides an all-round exhaust channel for the splicing of the upper and lower plates, ensuring that the vertical splicing and horizontal splicing have the same smooth installation experience.

[0048] (8) This utility model allows for fine adjustment of the height of the board after assembly by adjusting the screws, which can adjust the gap between the upper and lower boards to ensure that the width of the joint is consistent in the later stage.

[0049] (9) This utility model ensures accurate positioning of the reference block by using a limiting strip, thereby guaranteeing the vertical force on the position of the adjusting screw, making the height adjustment process smooth and precise, and preventing jamming due to the offset of the reference block. At the same time, it can also effectively position the reference block to ensure the accurate position of the adjusting bolt.

[0050] (10) The extension design of the reference block in this utility model realizes the linkage adjustment of adjacent wall panels, simplifies the adjustment process when splicing multiple panels, and makes the leveling operation of the overall wall panel more efficient and convenient.

[0051] (11) The auxiliary fixing connector in this utility model generates a strong tension force through the lever principle. Its function is to lock the wall panel firmly to the building body after it is smoothly slidably installed, thus ensuring the safety and stability of the final use.

[0052] (12) The planar splicing component of this utility model allows the wall panel to be moved along the first splicing body to adjust the splicing seam. However, through the interlocking of the first and second fastening strips, it can restrict the relative tilting of the wall panel, making the splicing between the wall panels quick and stable. At the same time, the locking strip can further stabilize the entire enclosed wall. And since the locking strip is set at the door or window, it is more convenient to insert the locking strip (because the door or window has a notch), and the construction difficulty is low.

[0053] (13) In this utility model, the corner of one wall panel is directly formed on the edging profile, and the wall panel splicing at the corner can be completed by simply splicing it with another wall panel on a plane. Because the corner is directly formed by the profile, the space tolerance is improved; at the same time, since the decorative surface layer is prefabricated and installed on it, the splicing seam at the corner is controllable and the top and bottom are neat and beautiful. At the same time, since the two wall panels spliced ​​at the corner are spliced ​​using normal wall panel plane splicing, the assembly difficulty is effectively reduced, and the interference problem is greatly improved.

[0054] (14) When the external corner splicing component of this utility model adopts the first splicing body and the second splicing body, it can adapt to various angle errors of the external corner of the wall through the fault tolerance fitting gap. That is, if there is an error in the external corner angle of the two wall panels forming the external corner, the fault tolerance fitting gap allows the two wall panels to be appropriately adjusted with the outer reference point as the rotation center, thereby improving the spatial fault tolerance and reducing the assembly difficulty. At the same time, the first positioning strip and the second positioning strip can play a positioning role when the prefabricated decorative surface layer is made, and can make the splicing seam formed by the decorative surface layer when the two adjacent wall panels are spliced ​​more beautiful.

[0055] (15) The internal corner splicing component of this utility model can make splicing construction simpler and has a high fault tolerance rate through the interlocking of the first and second buckle parts. It can be effectively adjusted by sliding and has a good interlocking restriction effect. At the same time, the splicing seam between two adjacent wall panels can be adjusted to achieve a uniform and beautiful splicing seam.

[0056] (16) The chassis structure of this utility model can effectively solve the waterproofing problem of the gap at the splicing of the upper convex part, which is conducive to improving the waterproofing of the chassis. At the same time, the first and second docking 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.

[0057] (17) The first and second contour 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.

[0058] (18) 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.

[0059] (19) 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.

[0060] (20) In this utility model, the first mating part and the first base plate splicing part are projected to coincide in their extension direction, and the second mating part and the second base plate splicing part are projected to coincide in their extension direction. This ensures that the first mating part of the first sealing member in the sealing assembly is naturally connected to the corresponding first base plate splicing part on the base plate, and the second mating part of the second sealing member is naturally connected to the corresponding second base plate splicing part on the base plate. Therefore, the first sealing member and the second sealing member can achieve interlocking when the two adjacent base plates are assembled together. This design also allows for further glue application to the splicing points of the base plate assembly when the sealing assembly is potted, further improving the overall waterproof sealing performance of the chassis.

[0061] (21) This utility model can further improve the glue retention capacity at the splicing point of the assembly components by using the first glue retention groove on the first base plate splicing part and the second glue retention groove on the second base plate splicing part, thereby further improving the waterproof sealing performance of the chassis.

[0062] (22) 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.

[0063] (23) This utility model can form the assembly benchmark of the decorative surface layer on the base plate through the first limiting flash and the second limiting flash, which greatly improves the standardization of the floor panel and the gap of the decorative surface layer after the later assembly is uniform and beautiful.

[0064] (24) 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.

[0065] (25) The bottom plate of this utility model has a built-in groove for threading heating cables. Of course, in order to ensure smooth threading and heat transfer efficiency, a threading metal pipe can be pre-embedded in the groove. Attached Figure Description

Heating cable 100. Detailed Implementation

[0068] (Example 1) See Figures 1 to 11The prefabricated kitchen and bathroom of this utility model includes a chassis 1 and a wall 2 assembled around the chassis; the chassis 1 includes multiple base plates 11 spliced ​​together; the wall 2 includes multiple wall panels 21 spliced ​​together around the chassis 1; each wall panel 21 includes two panels spliced ​​together in the vertical direction by connecting components; each panel includes a wall base plate and an edging profile covering the perimeter of the wall base plate; the perimeter of the chassis 1 formed by the multiple base plates 11 forms an upwardly protruding first interlocking body 12; the edging profile at the lower end of the lowest panel is provided with an interlocking body 12. A first splicing slot 22 with a matching shape; the first splicing slot 22 extends from one end of the edging profile to the other end; the wall panel 21 is spliced ​​by interlocking with the first splicing body 12 on the chassis 1 through the first splicing slot 22; the connecting component 3 includes a second splicing body 31 and a second splicing slot 32 disposed on the upper and lower panels and located at the splicing point of the upper and lower panels; two adjacent upper and lower panels are spliced ​​by interlocking with the second splicing body 31 and the second splicing slot 32; the second splicing body 31 and the second splicing slot 32 are respectively integrally disposed with the edging profile of the panel.

[0069] The second splicing body 31 is disposed at the upper end of the lower plate and is integrally formed with the edge trim of the lower plate; the second splicing slot 32 is disposed at the lower end of the upper plate and is integrally formed with the edge trim of the upper plate.

[0070] The inner wall of the first splicing slot 22 is provided with a first exhaust groove 23 extending along the extension direction of the first splicing slot 22. When the first splicing slot 22 is inserted into the first splicing body 12, the first exhaust groove 23 and the surface of the first splicing body 12 surround each other to form a first exhaust cavity. The inner wall of the second splicing slot 32 is provided with a second exhaust groove 321. When the second splicing slot 32 is inserted into the second splicing body 31, the second exhaust groove 321 and the surface of the second splicing body 31 surround each other to form a second exhaust cavity.

[0071] The upper end face of the first interlocking body 12 has a circular arc shape; the cross-section of the first interlocking slot 22 is also a circular arc shape that matches the first interlocking body 12; the upper end face of the second interlocking body 31 has a circular arc shape; the cross-section of the second interlocking slot 32 is also a circular arc shape that matches the second interlocking body 31. The first exhaust groove 23 includes a first intermediate air groove 231 and first lateral air grooves 232 symmetrically arranged on both sides of the first intermediate air groove 231; the first intermediate air groove 231 is located at the arc apex of the first splicing slot 22; The second exhaust groove 321 includes a second intermediate air groove 3211 and second lateral air grooves 3212 symmetrically arranged on both sides of the second intermediate air groove 3211; the second intermediate air groove 3211 is located at the arc apex of the second splicing slot 32.

[0072] The second interlocking body 31 has an adjustment groove 311 extending along the extension direction of the second interlocking body 31 at the arc apex position; an adjustment component is provided in the adjustment groove 311; the adjustment component includes a reference block 4 and an adjustment screw 5; the reference block 4 is disposed in the adjustment groove 311; the reference block 4 has a threaded through hole; the reference block 4 is fixedly connected in the adjustment groove 311 after the adjustment screw 5 passes through the threaded through hole and pierces the bottom of the groove 311; the upper end of the adjustment screw 5 is an adjustment head 51; the adjustment head 51 has an adjustment part that allows a tool to turn the adjustment screw; by adjusting the screwing depth of the adjustment screw 5, the height of the adjustment head 51 extending out of the groove of the adjustment groove 311 is controlled; when the adjustment head 51 extends out of the adjustment groove 311, it acts on the bottom of the second intermediate air groove 3211 and lifts the plate above.

[0073] The bottom of the adjustment groove 311 is provided with two limiting strips 3111 extending along its extension direction; the reference block 4 is disposed between the two limiting strips 3111, and the reference block 4 is located directly below the opening of the adjustment groove 311 under the positioning of the two limiting strips 3111.

[0074] The reference block 4 is flat; the reference block 4 is also provided with an extension end 41, which is used to insert into the adjustment groove 311 of the same height of the adjacent wall panel 21; the extension end 41 is also provided with a threaded through hole, and the threaded through hole is used to equip the adjustment screw 5 which is fixedly connected to the adjustment groove 311 of the adjacent wall panel 21.

[0075] Each plate has a tensioning groove 24 on the edge profile at the upper end; each tensioning groove 24 is equipped with at least one auxiliary fixing connector 6; the auxiliary fixing connector 6 is an integral rigid component, including a tensioning part 61, a lever part 62 and a connecting part 63 connected in sequence; The tensioning groove 24 includes an L-shaped groove; the L-shaped groove includes an upwardly extending vertical groove and a laterally extending horizontal groove; one end of the horizontal groove forms an opening of the L-shaped groove, which faces the building wall for fixing the wall panel 21; the other end of the horizontal groove is connected to the lower end of the vertical groove and forms an L-shaped groove. The tensioning part 61 is inserted into one end of the L-shaped groove and slidably disposed in the vertical groove; the lever part 62 is slidably disposed in the horizontal groove and extends out from the opening; the connecting part 63 extends vertically upward and beyond the upper end of the plate. The tensioning part 61 is tilted towards the connecting part 63; the vertical groove and the tensioning part 61 form a clearance fit; this clearance fit is configured such that when the connecting part 63 is attached to and fastened to the building wall (the fastening method is generally to pass a wall nail through the connecting part 63 and then into the building wall), the driving lever part 62 acts as a fulcrum in the horizontal groove, causing the tensioning part 61 to press tightly against the inner wall of the vertical groove near the building wall. After the connecting part 63 is fixedly connected to the building wall, the tight fit between the auxiliary fixing connector 6 and the tensioning groove 24 can effectively prevent the wall panel from shaking with the auxiliary fixing connector 6, resulting in a better fixing effect of the wall panel 21.

[0076] See Figures 12 to 17 as well as Figures 23 to 26 Adjacent wall panels 21 are spliced ​​together by wall assembly components; the wall assembly components include a planar splicing component 7 for splicing at flat surfaces, an external corner splicing component 8 for splicing at external corners, and an internal corner splicing component 9 for splicing at internal corners; The planar splicing component 7 includes a first fastener 71 and a second fastener 72 that interlock with each other; the first fastener 71 and the second fastener 72 are integrally mounted on the longitudinal edging profiles of the same height panels of two adjacent wall panels 21; both the first fastener 71 and the second fastener 72 extend from one end of the edging profile to the other end; the first fastener 71 is bent inward and its free end forms a first hook 711; the second fastener 72 is bent outward and its free end forms a second hook 721; the first fastener 71 and the edging profile form a structure that allows the second fastener 72 to be inserted. A first fastening groove is provided within which the second hook 721 can slide; the second fastening strip 72 and the surrounding edge form a profile within which the first fastening strip 71 can be inserted and the first hook 711 can slide; when two adjacent wall panels 21 are spliced ​​on a plane, the first fastening strip 71 and the second fastening strip 72 of the same height are respectively inserted into the corresponding second fastening groove and the first fastening groove, and after sliding adjustment in the splicing plane direction, the first hook 711 and the second hook 712 interlock; the interlocking of the first hook 711 and the second hook 712 restricts the relative tilting of the two adjacent panels. Specifically, when the first fastening strip 71 and the second fastening strip 72 of the same height are respectively inserted into the corresponding second fastening groove and the first fastening groove, the first hook 711 and the second hook 712 have not yet interlocked. Instead, one of the wall panels 21 must be moved horizontally before the first hook 711 and the second hook 712 interlock, thus restricting the relative tilting of the two adjacent panels.

[0077] The external corner splicing assembly 8 includes an external corner extension 81; the external corner extension 81 is disposed on one of the wall panels 21 spliced ​​to form an external corner; and the edging profile of the wall panel 21 is integrally disposed; the external corner extension 81 includes a first extension 811 and a second extension 812 integrally joined to form an external corner shape; both the first extension 811 and the second extension 812 extend from one end of the edging profile to the other end; the first extension 811 is integrally connected to the edging profile, and the second extension 812 is provided with a second fastening strip 72; the second fastening strip 72 on the external corner extension 81 and the first fastening strip 71 of the other wall panel 21 spliced ​​to form an external corner are interlocked; The internal corner splicing component 9 includes a first splicing profile 91 and a second splicing profile 92; the first splicing profile 91 and the second splicing profile 92 are respectively integrally disposed on the longitudinal edge-sealing profile of the splicing side of the two wall panels 21 forming the internal corner; the first splicing profile 91 and the second splicing profile 92 both extend from one end of the edge-sealing profile to the other end; The first splicing profile 91 includes an outward extension body 911 and a first fastening strip 912; the outward extension body 911 extends from the edging profile toward the splicing side away from the wall panel 21 and extends beyond the splicing side of the wall panel 21; the first fastening strip 912 is connected to the outward extension body 911 as a whole; the first fastening strip 912 extends from the inner surface of the wall panel 21 to the outer surface and extends beyond the outer surface of the wall panel 21; one end of the first fastening strip 912 that extends beyond the outer surface of the wall panel 21 forms a first fastening part; the second splicing profile 92 includes a second fastening strip 921; the second fastening strip 921 is bent to form a second fastening part; two adjacent wall panels 21 are spliced ​​by interlocking the first fastening part and the second fastening part of the same height on the panel.

[0078] See Figure 13 It also includes a locking strip 73; at least two adjacent wall panels in the wall 2, which are sequentially assembled around the first interlocking body 12 of the chassis 1 using wall assembly components, have second fasteners 72 at their joints. These two second fasteners 72 cooperate to form a locking engagement part that is compatible with the locking strip 73; by engaging the locking strip 73 with the locking engagement part, the wall 2, which is sequentially assembled around the first interlocking body 12 of the chassis 1 using wall assembly components, is locked in place. One of the second fasteners 72 forming the locking engagement part is located on the wall panel directly above the doorway or on the wall panel 21 directly above and / or directly below the window. This design is because the doorway and window will form an open area (reserved space for installing a door or window) when the wall panels 21 are assembled, thus facilitating the insertion of the locking strip 73 into the locking engagement part at this location.

[0079] The cross-sections of the first buckle 912 and the second buckle 921 are both hook-shaped; The first buckle strip 912, along its extending direction, sequentially includes a first connecting base 9121, a first bent body 9122, and a first hook-shaped free end 9123; the second buckle strip 921, along its extending direction, sequentially includes a second connecting base 9211, a second bent body 9212, and a second hook-shaped free end 9213; the first bent body 9122 and the first hook-shaped free end 9123 form a first buckle portion; the second bent body 9212 and the second hook-shaped free end 9213 form a second buckle portion. The first connecting base 9121 is connected to the outer extension body 911. The first connecting base 9121 extends from the inner surface of the wall panel 21 to the outer surface and extends beyond the outer surface of the wall panel 21. The first bending body 9122 and the outer extension body 911 form a first adjusting groove 9124 through the first connecting base 9121. The first hook-shaped free end 9123 and the outer extension body 911 have a first insertion port 9125. The second bent body 9212 is connected to the edge trim of the splicing side of the wall panel 21. The second bent body 9212 and the edge trim form a second adjustment groove 9214 through the second connecting base 9211. The second hook-shaped free end 9213 forms a second insertion port 9215 with the edge trim facing inward. After the first and second latching parts are inserted into the second insertion port 9215 and the first insertion port 9125 respectively, the first hook-shaped free end 9123 and the second hook-shaped free end 9213 form an interlocking engagement.

[0080] The first adjustment groove 9124 is used for sliding adjustment of the second latching part along the extension direction of the first connecting base 9121; the second adjustment groove 9214 is used for sliding adjustment of the first latching part along the extension direction of the second connecting base 9211; the extension direction of the first connecting base 9121 is consistent with the extension direction of the second connecting base 9211; after the first latching part and the second latching part are respectively inserted into the second insertion port 9215 and the first insertion port 9125, they form an interlocking fit by sliding the first latching part and the second latching part towards each other.

[0094] The assembly and debugging process of chassis 1 in this utility model is as follows: Based on the kitchen and bathroom space to be constructed, design the number and splicing method of the base plates 11 to be assembled. Then manufacture the base plates 11 of this utility model, and pre-install the corresponding sealing components 16 on the base plates 11.

[0095] During the on-site chassis construction, according to the design plan, a base plate 11 is first tilted and placed into the kitchen and bathroom space. After the first base plate 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 base plate splicing slot 1312 and the first mating part 1612. Next, the second base plate is tilted and placed in, its position is adjusted, and it is then interlocked with the first base plate.

[0096] Assemble the other base plates 11 in the above manner to form the chassis 1.

[0097] Then, the construction workers stand on the chassis 1 and use adjusting tools to level the chassis at the adjusting end 182 of the adjusting screw 18. Finally, glue is injected through the glue injection hole 164 to achieve a seal at the joint between the first sealing component 161 and the second sealing component 162, further improving the overall sealing performance of the chassis 1.

[0098] The chassis 1 assembly was completed in the manner described above.

[0099] Before inserting the base plate 11, a shim 19 is placed at the position corresponding to the adjusting screw 8. Then, the support end 181 of the adjusting screw 18 is placed on the shim 19. (See below) Figure 37 .

[0100] Meanwhile, when installing the heating cable 100, since the base plate 11 is equipped with a threading groove 11b-1 or a threading metal tube 11f, the heating cable 100 can be directly threaded using threading equipment. After threading, both ends of the heating cable 100 will extend from the threading inlet and threading outlet, facilitating subsequent wiring. Since threading the heating cable 100 using threading equipment is a standard operating procedure, the threading equipment and specific threading procedures will not be described in detail here.

[0101] (Example 2) See Figure 18In this utility model, a partition mounting strip 813 is embedded in the second extension 812.
