Technical Field

[0001] The invention relates to a toilet wall panel assembly, belonging to the technical field of indoor building decoration. Background Art

[0002] The installation sequence of existing prefabricated bathroom walls is to install all the internal corner keels first and then install the wall panels. In the actual operation process, the installation and adjustment of the internal corner keels and the external corner keels are relatively time-consuming and partially depend on the construction experience of the operators.

[0003] For example, prior art publication number CN201910297075.3 discloses an assembled toilet and an installation method thereof, comprising a base arranged on the ground, a bottom keel arranged around the base, a wall structure arranged above the bottom keel, a top keel arranged above the wall structure, and a top panel fixedly arranged on the top keel; wherein: the base is divided into a dry area base and a wet area base, and a water retaining strip is arranged above the adjacent parts of the dry area base and the wet area base; the bottom keel is provided with a first card slot for connecting the base, a second card slot for connecting the wall structure and a first hook for hanging a drainage profile cover; the wall structure comprises a wall surface layer and a connecting keel for connecting the wall surface layer; the top keel is provided with a third card slot for connecting the wall surface layer and a fourth card slot for connecting the top panel; the top surface of the toilet has at least one top panel, and a first buckle edge is arranged around the ceiling panel, and the ceiling panel is fixedly arranged on the top keel by the first buckle edge. The base is an independent dry area base and a wet area base, which is easy to install and transport. The wall and the ceiling are fixed and installed through the keel. The invention has a simple structure, modular and standardized production in the factory, reliable waterproofing, stable quality, simple and fast on-site construction, and promotes better development of prefabricated decoration.

[0004] For another example, prior art publication number CN201922198278.5 discloses an assembled bathroom wall panel system, including wall panels, a positive corner splicing structure and a negative corner splicing structure. The positive corner splicing structure includes an F-shaped column and a positive corner column, and the negative corner splicing structure includes two F-shaped columns and a negative corner column. The F-shaped column is a profile with a roughly F-shaped cross section, including two first edge strips, a first fixing strip, a second fixing strip, a first slot and a second slot. The first slot is formed by two first edge strips for inserting the side end of one of the wall panels; the positive corner column includes a positive corner column body, two second edge strips fixedly connected to the positive corner column body, and a 7-shaped positive corner plug-in strip; the positive corner column body is located at the angle between the two wall panels, and a third slot is formed between the two second edge strips for inserting the side end of the other wall panel. The assembled bathroom wall panel system of the utility model can realize the rapid and high-precision installation of bathroom wall panels, significantly reducing costs and having strong applicability.

[0005] The wall panels of these two bathroom systems are generally simple in structure, and have certain defects in terms of structural strength and deformation resistance. In addition, the surface visual styles of these two prior art wall panels are relatively traditional, so the commercial added value is relatively low. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a bathroom wall panel assembly with good overall structural strength and good anti-deformation performance.

[0007] The present invention is achieved through the following technical solutions.

[0008] A bathroom wall panel assembly includes a first panel body located on the outer layer, at least two second panel bodies located on the inner layer, and a splicing keel for splicing adjacent first panel bodies, wherein the side edge of the first panel body is integrally connected with a first side edge portion close to the outer layer panel and a second side edge portion close to the inner layer panel, and a first gap groove is provided between the two, and the splicing keel is fixedly connected to the two adjacent first panel bodies and is snap-fitted with the first gap groove.

[0009] As a further improvement of the present invention, the first panel body includes an inner layer plate adhered and fixed to the second panel body, an outer layer plate spaced apart from the inner layer plate, and a plurality of vertical partition plates, wherein the vertical partition plates are integrally connected to the inner layer plate and the outer layer plate and enclose a plurality of vertical through holes.

[0012] As a further improvement of the present invention, the second panel body includes a plurality of unit panels with arbitrary length and width, a plurality of linear transverse splicing components, and a plurality of linear longitudinal splicing components. The plurality of unit panels are stacked into a rectangular plate structure. The opposite sides of two adjacent unit panels have splicing grooves extending along the length direction of the opposite sides. The transverse splicing components / longitudinal splicing components are respectively engaged with the splicing grooves of the opposite sides of the two adjacent unit panels.

[0014] As a further improvement of the present invention, the horizontal splicing component / longitudinal splicing component includes a mounting member and a caulking strip, both of which are linear. The mounting member has a main body portion located in the gap between the opposite edges of the two unit boards, two snap-fitting portions connected to the two sides of the main body portion and respectively snap-fitted with the splicing grooves on the opposite edges of the two unit boards, a wall-adhering portion connected to the first end of the main body portion close to the first panel body and attached to the backs of the two unit boards, the wall-adhering portion is fixedly connected to the first panel body, and a plug-in groove extending along the length direction of the mounting member is provided at the second end of the main body portion away from the first panel body, and the caulking strip has a plug-in portion plug-fitted with the plug-in groove, and an edge sealing portion connected to the first end of the plug-in portion and closing the gap between the opposite edges of the two unit boards.

[0015] As a further improvement of the present invention, the plug-in portion is inserted into the plug-in slot and has multiple first protrusion structures on both sides extending along the length direction of the mounting piece and arranged side by side. The two groove walls of the plug-in slot have a second protrusion structure close to the groove or multiple second protrusion structures close to the groove and arranged side by side extending along the length direction of the mounting piece. When the plug-in portion and the plug-in slot are relatively displaced along the plug-in direction, the second protrusion structure can be squeezed by the first protrusion structure passing by in sequence. When the second end of the plug-in portion abuts against the bottom of the plug-in slot, the second protrusion structure is staggered with the first protrusion structure.

[0033] The present invention is further described in detail below based on the accompanying drawings and implementation examples.

[0034] The directional terms such as up, down, left, right, front, back, front, back, top, bottom, etc. mentioned or may be mentioned in this specification are defined relative to the structures shown in the drawings. The words "inside" and "outside" refer to the direction toward or away from the geometric center of a specific component, respectively. They are relative concepts, and therefore may change accordingly according to different locations and different usage conditions. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0035] Reference Figure 1-Figure 12 A bathroom frame assembly comprises: a bottom frame 3, a top frame 4, a plurality of wall panels W, a female corner keel 5, a male corner keel 6, and a plurality of adjustment mechanisms 7. The bottom frame 3 is a structure having a plurality of corners and extending linearly. Specifically, a linear structure is provided between adjacent corners. A gap is left between the two ends of the bottom frame 3 for installing a door frame of the bathroom. The female corner keel 5 or the male corner keel 6 is correspondingly arranged at each corner of the bottom frame 3. The female corner keel 5 and the male corner keel 6 are arranged upright, and the bottom end is positioned at the corner position of the bottom frame 3. The wall panel W is a rectangular structure, the bottom side of which is fixedly connected to the bottom frame 3, and the side side is fixedly connected to the female corner keel 5 / male corner keel 6. The fixed frame is fixed to the top side of the wall panel W. The adjustment structure is supported between the bottom frame 3 and the ground and its height is adjustable.

[0036] The bottom frame 3 includes a plurality of straight bottom frames, the ends of the bottom frames have oblique cutouts and two adjacent bottom frames are spliced ​​at the ports to form the corners of the bottom frame 3. Usually, the cutouts at the ends of the bottom frames are 45°, i.e., the corners are 90°. The bottom frame includes a vertical frame plate 31, a flat frame plate 32, and a frame seat 33 extending along its length direction. The outer side and the inner side of the vertical frame plate 31 are respectively connected to the frame seat 33 and the flat frame plate 32 as one body. The vertical frame plate 31 and the flat frame plate 32 form an L-shaped structure. The upper surface of the flat frame plate 32 is a horizontal positioning surface corresponding to the wall panel W. The bottom edge of the wall panel W is attached to the horizontal positioning surface of the flat frame plate 32, and the vertical frame plate 31 is attached to the wall panel W and fixedly connected by fasteners. It should be noted that the wall panel W is a rectangular structure, and its bottom edge is attached to the horizontal positioning surface of the bottom frame. The inner corner keel 5 / the outer corner keel 6 is fixedly connected to the wall panel W. Therefore, whether the bottom frame is kept in a horizontal state determines the squareness of the wall panel W and the inner corner keel 5 / the outer corner keel 6. The installation steps of the prior art are to pre-install the inner corner keel 5 / the outer corner keel 6 at the designated position of the building wall, and then fix the wall panel W. In the actual operation process, due to space limitations, the squareness and position adjustment of the inner corner keel 5 and the outer corner keel 6 takes a long time, and the operation difficulty is relatively large. Different from the prior art, the bathroom frame assembly of the present embodiment is an independent integral sanitary frame, which is moved in as a whole after all the assembly is completed, and there is no need to adjust the squareness of the internal corner keel 5 / external corner keel 6. During installation, the internal corner keel 5 / external corner keel 6 is first fixedly connected to the wall panel W on one side, and then the bottom edge of the wall panel W is attached to the horizontal positioning surface of the corresponding bottom frame and the two are fixedly connected using fasteners, and then the bottom edge of the wall panel W on the other side is attached to the horizontal panel of the corresponding bottom frame and the two are fixedly connected using fasteners, and then the wall panel W is fixedly connected to the internal corner keel 5 / external corner keel 6.

[0037] The frame seat 33 includes two hollow step structures extending side by side along the length direction of the bottom frame. The two step structures are respectively recorded as the first step structure 331 and the second step structure 332 from bottom to top. The first step structure 331 is aligned with the flat frame plate 32, and the width of the first step structure 331 is greater than that of the second step structure 332. The structural arrangement of the first step structure 331 and the second step structure 332 improves the stability of the center of gravity of the bottom frame and the bottom frame 3, and can prevent the wall panel W from tilting.

[0038] The floor corresponding to the bathroom frame should be flat, and the bottom frame 3 placed directly on the floor is horizontal, which can ensure the squareness of the wall panel W and the inner corner keel 5 / outer corner keel 6. However, the actual situation of bathroom decoration cannot ensure that the bathroom floor is completely flat, so it is necessary to debug the adjustment mechanism 7 to ensure that the bottom frame and the bottom frame 3 remain horizontal. The bottom of the frame seat 33, that is, the bottom surface of the first step structure 331, is provided with a mounting hole that allows the adjustment mechanism 7 to pass through, and the portion where the first step structure 331 and the second step structure 332 are connected is correspondingly provided with a through hole that allows the adjustment structure to pass through. In addition, the first step structure 331 and the second step structure 332 are both hollow structures, which can meet the space required to accommodate the adjustment mechanism 7.

[0039] The adjustment mechanism 7 includes a support seat 71, an adjustment rod 72, and an adjustment member 73. The support seat 71 is a columnar structure, which passes through the mounting hole on the bottom surface of the first step structure 331 and can slide vertically relative to the mounting hole. A vertical guide channel is provided on the top of the support seat 71, and the adjustment rod 72 is inserted in the guide channel. The adjustment rod 72 can slide vertically relative to the support seat 71 and can also rotate around its axial direction. The top end of the adjustment rod 72 is supported on the top of the frame seat 33, i.e., the second step structure 332. The support seat 71 has a first matching structure 7-A with the adjustment rod 72 as the central axis and extending in a spiral. Specifically, the top surface of the support seat 71 has a spiral slope with the adjustment rod 72 as the central axis. The first matching structure 7-A is A step structure is arranged along the extension direction of the slope, and the adjusting member 73 is a strip structure perpendicular to the adjusting rod 72 and fixed to the part of the adjusting rod 72 located outside the support seat 71. One end of the adjusting member 73 has a second matching structure 7-B extending downward, and the second matching structure 7-B is a step structure matching the first matching structure 7-A. The other end of the adjusting member 73 has a pull structure 7-C, and the pull structure 7-C is a manually adjustable structure. The adjusting rod 72 can be manually driven to rotate around its axis, so as to adjust the position where the second matching structure 7-B is combined with the first matching structure 7-A to regulate the height of the adjusting mechanism 7, and then the bottom frame can be adjusted to a horizontal state through multiple adjustment mechanisms 7 corresponding to a single bottom frame.

[0040] As for height adjustment, since the ground is generally horizontal as a whole but is partially uneven or has potholes, multiple adjustment mechanisms 7 need to be adjusted to ensure that the corresponding bottom frame is level. Therefore, the height adjustment range of the adjustment mechanism 7 is small, and fine-tuning is sufficient. The first matching structure 7-A and the second matching structure 7-B are set as matching step structures, and the second matching structure 7-B moves one step, i.e., one fine-tuning unit, relative to the first matching structure 7-A. Through multiple fine-tuning, the optimal height can be gradually approached and finally adjusted to, thereby avoiding excessive adjustment caused by poor control of a single adjustment range and the need for repeated adjustment.

[0041] In order to facilitate the adjustment of the height of the adjustment mechanism 7, a window 332-H is provided on the outer surface of the second step structure 332 corresponding to the position of the adjustment mechanism 7, and the user can directly manually control the pull structure 7-C through the window 332-H. This structural setting can hide most of the adjustment mechanism 7 inside the bottom frame, which not only makes the adjustment mechanism 7 not exposed and optimizes the appearance, but also reduces the overall height of the bottom frame 3 and the adjustment mechanism 7, so as to achieve the purpose of streamlining the structure. In addition, in this embodiment, the bottom frame also includes a cover plate 34 extending and erected along the length direction of the bottom frame, the height of the cover plate 34 matches the height of the outer surface of the second step structure 332, and the side facing the outer surface of the second step structure 332 is provided with a plurality of snap-on structures 341 that can be plugged in and matched with the window 332-H. After the horizontal adjustment of the bottom frame is completed, the cover plate 34 is plugged into the outer surface of the second step structure 332 to cover the window 332-H.

[0042] When adjusting the levelness of the bottom frame and the bottom frame 3, since the bottom frame is light in weight, the lever structure 7-C can be easily twisted to adjust it higher or lower. Then, after the wall panel W and the bottom frame are fixed, the support object of the adjustment rod 72 is the wall panel W and the bottom frame. Under the action of the gravity of the two, the first matching structure 7-A and the second matching structure 7-B are combined with better strength, which can avoid relative displacement between the two and cause offset of the combination position.

[0043] In order to prevent the adjustment mechanism 7 from rotating relative to the bottom frame during movement after assembly and to improve the stability of the adjustment mechanism 7 relative to the bottom frame, the support seat 71 is set to a columnar structure, and its cross-section is set to be non-circular, and the mounting hole is also set to match the shape of the cross-section, so that the support seat 71 can not only slide vertically along the mounting hole but cannot rotate. In this embodiment, the first matching structure 7-A is spirally extended around the top side of the support seat 71, and correspondingly, the support seat 71 is set to a columnar structure with a fan-shaped cross-section.

[0044] A disc-shaped connecting piece 35 is fixed to the inner surface of the top of the second step structure 332. The connecting piece 35 has a cavity inside and a through hole connecting the cavity is provided at the center of its bottom surface. The adjusting rod 72 passes through the connecting piece 35 through the through hole, and the part of the adjusting rod 72 located in the connecting piece is fixed with a connecting structure 36 embedded in the cavity and rotatable relative to the connecting piece 35, so that the adjusting rod 72 can be connected to the frame seat 33 without restricting the rotation of the adjusting rod 72.

[0045] The wall panel W includes a first panel body 1 located at the outer layer and a second panel body 2 located at the inner layer. For a wall panel W with a smaller area, only one first panel body 1 is required. For a wall panel W with a larger area, at least two first panel bodies 1 are provided and are spliced ​​together by a splicing keel 8.

[0046] The first panel body 1 includes an inner panel 11 fixed to the second panel body 2, an outer panel 12 spaced apart from the inner panel 11, and a plurality of vertical partitions 13, wherein the vertical partitions 13 are integrally connected with the inner panel 11 and the outer panel 12 and enclose a plurality of vertical through holes. Firstly, the structure with vertical through holes can save materials to control costs, and secondly, the thickness of the first panel body 1 can be appropriately increased while controlling its weight to reduce the load of the bottom frame 3, and furthermore, the propagation speed of sound waves in the air medium is lower than that in the solid medium, so it can also play a certain sound insulation effect.

[0047] The outermost vertical partition plate of the first panel body 1 is integrally connected to the first side portion 1-A and the second side portion 1-B which are surrounded by multiple vertical side panels 14 and form a vertical through hole. Both are square vertical tube structures, wherein the first side portion 1-A is close to the outer layer plate 12, and the second side portion 1-B is close to the inner layer plate 11, and there is a first gap groove 1-j between the first side portion 1-A and the second side portion 1-B.

[0048] The splicing keel 8 includes a splicing main body 81, a splicing clamping part 82, and a splicing bonding part 83. The splicing main body 81 is a vertical hollow square tube structure, and its left and right side surfaces are respectively bonded with the first side edges 1-A of the two adjacent first panel bodies 1. The splicing clamping part 82 is a vertical plate-like structure, which is symmetrically connected to the inner side of the splicing main body 81. The thickness of the left and right parts of the splicing clamping part 82 matches the groove width of the first gap groove 1-j and is snap-fitted therewith. A layer of elastic material can also be wrapped around the left and right parts of the splicing clamping part 82 and its overall thickness can be slightly larger than the first gap groove 1-j. When snap-fitted, the elastic material is squeezed and compressed to increase the friction between the splicing clamping part 82 and the first gap groove 1-j to avoid relative sliding between the two. In addition, there is a second gap groove 1-k between two adjacent second side portions 1-B. After the first panel bodies 1 are spliced, a leveling device can be used to insert and position the second gap groove 1-k, and then detect whether the adjacent two inner layer panels 11 are flat after splicing. The splicing and bonding portion 83 is an upright plate-like structure, which is symmetrically connected to the outer side of the splicing main body 81. The left and right parts of the splicing and bonding portion 83 are respectively bonded to the outer surfaces of the adjacent two outer layer panels 12, and the two are fixedly connected by fasteners.

[0049] With regard to the splicing keel 8 and the two first panel bodies 1 spliced ​​thereto, firstly, the splicing effect of the two first panel bodies 1 is provided through the snap-fit ​​cooperation between the splicing clamping portion 82 and the two first gap grooves 1-j, and the contact area between the splicing keel 8 and the two first panel bodies 1 is increased, thereby enhancing the bonding strength. Secondly, the splicing fitting portion 83 of the splicing keel 8 is fixedly connected to the two first side portions 1-A, and is not fixedly connected to the second side portion 1-B. Therefore, when the wall panel W is subjected to external force and has a tendency to bend, especially at the splicing portion, the first side portion 1-A and the splicing keel 8 are mainly subjected to the bending deformation. Since the second side portion 1-B is not directly connected to the splicing keel 8 and there is a second gap groove 1-k, the second side portion 1-B is less affected, thereby reducing the bending effect on the second panel body 2.

[0050] The visual style of the second panel body is the Mondrian grid pattern. It has good ornamental value and three-dimensional visual sense when applied to the inner wall of the bathroom. Its aesthetics can increase more added value. The second panel body includes a plurality of unit panels 23, a plurality of linear transverse splicing components M, and a plurality of linear longitudinal splicing components N. The unit panels 23 have lengths and widths of arbitrary sizes, and the color of the front side is any single color. A plurality of unit panels 23 are assembled into a rectangular plate-shaped total wall body. The opposite sides of two adjacent unit panels 23 have splicing grooves extending along the length direction of the opposite sides. The transverse splicing components M / longitudinal splicing components n are respectively engaged with the splicing grooves of the opposite sides of the two adjacent unit panels 23.

[0051] The horizontal splicing component M / vertical splicing component N is composed of one or more horizontal splicing components M / vertical splicing components n, and the two ends of the horizontal splicing components M / vertical splicing components n intersect with the edge of the above-mentioned total wall or intersect with the longitudinal splicing components / horizontal splicing components M in a T-shape. For the partitioning of the horizontal splicing component M / vertical splicing component N, the shorter one is partitioned by the longer one when intersecting, that is, any two intersecting horizontal splicing components M and longitudinal splicing components N, the shorter horizontal splicing component M / vertical splicing component N and the longer longitudinal splicing component N / horizontal splicing component M are partitioned into two horizontal splicing components M / vertical splicing components n at the intersection, and the separated ends of the two horizontal splicing components M / vertical splicing components n intersect with the longitudinal splicing component N / horizontal splicing component MT in a T-shape respectively.

[0052] Under the above-mentioned partition scheme of horizontal splicing component M / vertical splicing component N, the integrity of the longer horizontal splicing component M / vertical splicing component N can be maintained as much as possible. This partition scheme is easy to follow in actual operation and the judgment is relatively simple. In addition, the integrity of the longer horizontal splicing component M / vertical splicing component N can reduce the deviation from the extension direction.

[0053] Regarding the connection relationship between the transverse splicing component / longitudinal splicing group and the unit board, the transverse splicing component / longitudinal splicing group includes a mounting member 21 and a caulking strip 22. The mounting member 21 and the caulking strip 22 are both linear structures. The mounting member 21 has a main body 211, two embedded parts 212 and a wall-attaching part 213. The mounting member 21 is used to connect two adjacent spliced ​​unit boards 23.

[0054] The cross-section of the main body 211 is slender with a certain width and extends along the thickness direction of the unit plate 23. The main body 211 is located in the gap between two adjacent unit plates 23. The end of the main body 211 facing the back of the unit plate 23 is defined as the first end 21-A, and the end facing the front of the unit plate 23 is defined as the second end 21-B. The first end of the main body 211 is integrally connected with the middle part of the wall-attached portion 213. The wall-attached portion 213 is a flat structure and is attached to the first panel body. The wall-attached portion 213 is provided with a reserved slot 2131 for a fastener, which can fix the unit plate 23 to the first panel body.

[0055] The two embedded parts 212 are integrally connected to the two sides of the main body 111, and the structure is symmetrical about the main body 211. Specifically, the embedded parts 212 are connected to the positions of the second end parts 21-B on both sides of the main body 211, and the relative sides 231 of the unit board 23 have splicing grooves 232 extending along the length direction of the relative sides 231. The two embedded parts 212 are respectively engaged with the splicing grooves 232 of the two adjacent unit boards 23. The splicing groove 232 has a first groove wall 2321 close to the front side of the unit board 23, a second groove wall 2322 close to the back side of the unit board 23, and a groove bottom 2323. The embedded part 212 has a first end face 2121 of the embedded part facing the first groove wall 2321, and a second end face 2122 facing the second groove wall 232. 2, and a third end face 2123 of the embedding portion facing the bottom of the groove, wherein the first end face 2121 of the embedding portion is flush with the second end 21-B of the main body 211, that is, the main body 211 and the two embedding portions 212 form a T-shaped structure, which enhances the structural strength of the mounting member 21 along the width direction of the gap, and there is a gap between the third end face 2123 of the embedding portion and the bottom 2323 of the splicing groove 232. Therefore, the embedding portion 212 has a certain assembly gap when it is engaged with the splicing groove 232, so as to prevent the mounting member 21 from being squeezed by the bottom 2323 of the groove when it is used for a long time and has problems such as aging and deformation, resulting in aggravated aging or even breakage. The second end face 2122 of the embedding portion is a bent surface after multiple bending.

[0056] The embedded part 212 is wrapped with a layer of flexible member matching its shape, which can be preferably made of rubber. Based on the structure of the embedded part 212, the flexible member 24 has a first flexible member 241, a second flexible member 242, and a third flexible member 243 that are integrally connected, and these three parts respectively cover the first end face 2121, the second end face 2122, and the third end face 2123 of the embedded part 212. Since the first end face 2121 of the embedded part is a plane, the first flexible member 241 as a whole is in friction contact with the first groove wall 2321, and the second end face 2122 of the embedded part is a bent surface, so the second flexible member 242 part is in friction contact with the second groove wall 2322, and the rest of the part has a gap with the second groove wall 2322. In general, the first end face 2121 of the embedding part and the first part 241 of the flexible component mainly play the role of preventing the embedding part 212 from being relatively displaced with the splicing groove 232 along its length direction, and combined with the structural feature that the first end face 2121 of the embedding part is flush with the second end 21-B of the main body 21, it has better snap-fitting performance. The second end face 2122 of the embedding part and the second part 242 of the flexible component partially prevent the embedding part 212 from being relatively displaced with the splicing groove 232, and more importantly, support the embedding part 212, thereby increasing the strength of the first part 241 of the flexible component in contact with the first groove wall 2321. In addition, since the second flexible component is only partially in frictional contact with the second groove wall 2322, the damping can be reduced when the embedding part 22 is inserted into the embedding groove, thereby simplifying the assembly difficulty.

[0057] The second end of the main body 211 is provided with a plug-in slot 2113 extending along the length direction of the mounting member 21, and the plug-in slot 2113 extends from the slot opening in the length direction of the cross section of the main body 211 to its slot bottom 2113-2, and the caulking strip 22 has a plug-in portion 221 and an edge sealing portion 222, and the cross section of the plug-in portion 221 is a slender structure, and the end thereof facing the back side of the unit board 23 is defined as a first end 22-A, and the end thereof facing the front side of the unit board 23 is defined as a second end 212-B, and the edge sealing portion 2122 is a flat structure, wherein the middle portion is integrally connected with the second end 212-B of the plug-in portion 2121, and the two constitute a caulking strip 212 with a T-shaped structure, and the edge sealing portion 2122 is used to close the gap between the opposite edges 231 of the two unit boards 23.

[0058] The plug-in portion 221 includes two parts, one part is plugged into the plug-in slot 2113 and is recorded as the second part 2212 of the plug-in portion, and the other part is exposed outside the plug-in slot 2113 and is recorded as the first part 2211 of the plug-in portion. Both sides of the second part 2212 of the plug-in portion have a plurality of first protrusion structures S extending along the length direction of the mounting member 21 and arranged side by side. The two groove walls 2113-1 of the plug-in slot 2113 have a second protrusion structure P that is close to the groove or a plurality of second protrusion structures P that are close to the groove and arranged side by side and extend along the length direction of the mounting member 21. In this embodiment, the groove wall of the plug-in slot 2113 is provided with two second protrusion structures P side by side along the position close to the groove.

[0059] When the plug-in portion 221 and the plug-in slot 2113 are relatively displaced along the plug-in direction, the second protruding structure P can be squeezed by the first protruding structure S that passes by in sequence. The relative displacement here refers to the process of plugging the plug-in portion 221 into the plug-in slot 2113 along the plug-in direction. When the plug-in portion 221 is inserted, the two first protruding structures S on both sides of the second portion 2212 of the plug-in portion close to the first end of the plug-in portion 221 first contact with the two second protruding structures P close to the slot, and the first protruding structures S squeeze the second protruding structures P laterally. Since the slot is farther from the bottom of the slot than other parts, it is easier to deform under squeezing, so that the spacing between the two second protruding structures P becomes larger, that is, the slot width at the slot is increased, thereby improving the smoothness of the second portion 2212 of the plug-in portion being inserted into the plug-in slot 2113. It is worth noting that during the extrusion process, the first protrusion structure S and the second protrusion structure P will also undergo a certain degree of deformation. Since the thickness of the second part 2212 of the plug-in part is relatively narrow, the first protrusion structure S integrated therewith has stronger rigidity, so that the deformation degree of the first protrusion structure S is smaller than that of the second protrusion structure P, which is beneficial to the insertion of the plug-in part 221. Therefore, the caulking strip 22 can be made of a material with stronger rigidity than the mounting part 21 to increase the deformation difference between the first protrusion structure S and the second protrusion structure P, thereby further improving the smoothness of insertion.

[0060] As the depth of the second part 2212 of the plug-in portion inserted into the plug-in slot 2113 increases, the first protrusion structures S on both sides of the second part 2212 of the plug-in portion sequentially pass through the second protrusion structure P and exert an extrusion effect on it, so that the slot width of the plug-in slot 2113 is intermittently increased and restored. In addition, it should be noted that the first protrusion structure S and the second protrusion structure P are continuous, that is, the adjacent first protrusion structure S / second protrusion structure P are connected uninterruptedly, which can speed up the frequency of "one closing and one closing" of the plug-in slot 2113 and reduce the resistance during the plug-in process. Of course, when the second end of the plug-in portion 221 abuts against the bottom of the slot 2113, that is, when the plug-in portion 221 is fully plugged into the plug-in slot 2113, the second protrusion structure P and the first protrusion structure S are interlaced, and the two do not squeeze each other at this time, and the plug-in slot 2113 is in a normal state and maintains a tight plug-in fit state with the second part of the plug-in portion.

[0061] Furthermore, the slot width of the plug slot 2113 is gradually reduced along the direction from the slot opening to the slot bottom, so that the second portion 2212 of the plug portion is more and more closely plugged into the plug slot 2113 during the insertion process, so as to improve the connection strength between the mounting member 21 and the caulking strip 22. If there is no first protruding structure S and second protruding structure P, the damping during insertion is very large, which not only increases the difficulty of plug-in operation, but may even cause the second end of the plug portion 221 to fail to contact the slot bottom of the plug slot 2113, and the plug portion 221 is also prone to breakage during the plug-in process. Therefore, under the premise of providing the first protruding structure S and the second protruding structure P, the solution of gradually reducing the slot width of the plug slot 2113 can be implemented.

[0062] The first protruding structure S has three continuous surfaces, namely, the first slope S1 close to the first end of the plug-in portion 221, the second slope S2 close to the second end of the plug-in portion 21, and the first curved surface S3 connecting the two, wherein the first slope S1 and the second slope S2 may have a certain curvature. Correspondingly, the second protruding structure P has three continuous surfaces, namely, the third slope P1 close to the bottom of the plug-in slot 2113, the fourth slope P2 close to the notch of the plug-in slot 2113, and the second curved surface P3 connecting the two, wherein the third slope P1 and the fourth slope P2 may also have a certain curvature. In fact, the first protruding structure S and the second protruding structure P are both centrally symmetrical in structure, so the first slope S1 and the fourth slope P2 have approximately the same inclination, and the second slope S2 and the third slope P1 have approximately the same inclination.

[0063] In addition, the inclination of the first slope S1 is smaller than that of the second slope S2. When the second part 2212 of the plug-in part is inserted into the plug-in slot 2113, the first slope S1 and the fourth slope P2 are relatively displaced until the first curved surface S3 and the second curved surface P3 are in contact and squeezed. Since the inclination of the first slope S1 and the fourth slope P2 is smaller, the resistance during insertion is also smaller. When the second part 2212 of the plug-in part is separated from the plug-in slot 213, the situation is the opposite. The second slope S2 and the third slope P1 are relatively displaced. Since the inclination of the second slope S2 and the third slope P1 is larger, the plug-in part 221 is not likely to have the caulking strip 22 separated from the mounting member 2 without human operation.

[0064] The groove bottom 213-2 of the plug-in groove 2113 and the intersection of the two groove walls 2113-1 are provided with a recessed structure Q extending along the length direction of the mounting member 21. The cross section of the recessed structure Q is an arc line and has a certain accommodation space. Therefore, the first protruding structure S closest to the first end on both sides of the plug-in portion 221 is engaged with the corresponding recessed structure Q. Combined with the first protruding structure S and the second protruding structure P, the main body 211 undergoes elastic deformation when the second part 2212 of the plug-in portion is inserted, and the groove width increases intermittently. After the final complete plug-in fit is reset, the connection between the two is tighter and not easy to loosen and fall off. The recessed structure Q can relieve the stress generated when the second part 2212 of the plug-in portion is inserted, thereby preventing the second part 2212 of the plug-in portion from being structurally damaged or easily caused by non-elastic irreversible deformation. There is a gap between the part of the recessed structure Q corresponding to the bottom of the groove and the first end 22-A of the plug-in part 221. Specifically, the first end of the plug-in part 221 is a planar structure, which can absorb the deformation of the recessed structure Q and the second end due to processing errors and thermal expansion and contraction, deformation stress during plug-in, etc., to prevent the unit board 23 from arching and deforming.

[0065] The main body 211 is divided into two parts. The part with the plug-in slot 2113 is recorded as the first part 2111 of the main body, and the part extending from the first part 2111 of the main body to the first end 21-A of the main body 211 is recorded as the second part 2112 of the main body. The width of the first part 2111 of the main body is greater than the width of the second part 2112 of the main body. Therefore, when the second part 2212 of the plug-in slot 2113 is inserted into the plug-in slot 2113, the first part 2111 of the main body and the plug-in slot 2113 are intermittently deformed, while the deformation of the second part 2112 of the main body is minimal. Therefore, the wall-attached part 213 connected thereto will not be displaced relative to the back sides of the two unit boards 23, thereby improving the local stability of the structure. In addition, the flexible component also has a fourth part 244 of the flexible component extending to the gap between the opposite edges 231 of the two unit plates 23. The fourth part 244 of the flexible component covers the first part 2111 of the main body and fits on the corresponding opposite edges 231 of the unit plate 23, which can protect the main body 211 and make the mounting component 21 have elastic buffering performance between the gaps of the two adjacent unit plates 23.

[0066] The internal angle keel 5 includes an internal angle fitting portion 51 and a internal angle connecting portion 52 which are connected in one piece. The internal angle fitting portion 51 is an upright plate-like structure, wherein the middle portion is bent into two parts along the vertical direction, and the bending portion is an arc-shaped surface. The portions extending to both sides of the bending portion are respectively fitted on the outer surfaces of the two adjacent first panel bodies 1 and the first side edge portion 1-A, and the two are fixedly connected using fasteners. The internal angle connecting portion 52 includes two vertically connected vertical plate-like structures, which are respectively connected to the two parts of the internal angle fitting portion 51. The internal angle connecting portion 52 is respectively fitted with the corresponding second side edge portion 1-B on the same side, and is spaced a certain distance from the corresponding first side edge portion 1-A on the same side. The internal angle keel 5 and the first panel bodies 1, the second panel body 2 on both sides, and the bottom frame at the bottom constitute the internal angle structure.

[0067] When the internal angle structure is deformed or has a tendency to deform due to external forces (for example, the part of the wall panel W near the internal angle is hit or squeezed), the internal angle structure acts as a buffer and absorbs the force, thereby reducing the destructive force on the wall panel W structure, so that the internal angle structure has better resistance to deformation. When the internal angle structure is subjected to external forces, the internal angle fitting portion 51 plays a role in bearing deformation or generating a tendency to deform, and the curved curved portion in the middle has a certain ability to withstand deformation, thereby reducing the risk of bending and deformation of the two wall panels W. In addition, the gap distance between the first side portion 1-A and the internal angle connecting portion 52 can also allow the internal angle structure to have a certain buffer space to reduce structural damage.

[0068] The external corner keel 6 includes an integrally connected external corner fitting portion 61, a first external corner supporting portion 62, a second external corner supporting portion 63, two external corner connecting portions 64, and a external corner spacing portion 65. The side edges of the two first panel bodies 1 connected to the external corner keel 6 are formed by cutting the first panel body 1 at an inclined angle along the vertical direction near the side edge. The formed structure is a notch structure composed of the outer layer plate 12, the inner layer plate 11 and the vertical partition plate 13 of the first panel body 1. The internal corner fitting portion 51 of the external corner keel 6 is bent in the middle, and its two parts are respectively fitted on the outer surfaces of the two adjacent first panel bodies 1, namely the outer layer plate 12, and the two are fixedly connected using fasteners. One end of the inner corner spacer is connected to the bend of the inner corner fitting part 51 to form a three-pronged structure. The two sides of the inner corner spacer are respectively fitted with the outer layer plates 12 and the inner layer plates 11 of the two adjacent first panel bodies 1. The outer corner first support part 62 is connected to the outer corner spacer 65 and is respectively fitted with the inner surfaces of the two adjacent outer layer plates 12. The outer corner second support part 63 is connected to the outer corner spacer 65 and is respectively fitted with the inner surfaces of the two adjacent inner layer plates 11. The two outer corner connecting parts 64 are respectively connected to the outer corner first support part 62 and the outer corner second support part 63 on the same side, and are fitted with the vertical partition plate 13 of the first panel body 1 closest to the outer corner keel 6. The outer corner keel 6 and the first panel bodies 1, the second panel body 2 and the bottom frame at the bottom form the outer corner structure.

[0069] The first supporting portion 62 of the external corner, the second supporting portion 63 of the external corner and the connecting portion 64 of the external corner form a snap-fit ​​structure that is snapped into the notch structure formed by the outer plate 12, the inner plate 11 and the vertical partition plate 13. This structural combination enables the external corner keel 6 and the first panel bodies 1 on both sides to have sufficient overall structural strength. In addition, the second supporting portion 63 of the external corner has a serrated texture on one side that is attached to the inner plate 11, which can enhance the friction coefficient between the second supporting portion 63 of the external corner and the inner plate 11 to avoid misalignment; the first supporting portion 62 of the external corner and the external corner attachment portion 61 clamp and fix the outer plate 12 of the first panel body 1. The two ways of strengthening the firmness of the external corner structure and the inner plate 11 and the outer plate 12 can comprehensively enhance the overall structural strength of the external corner structure.

[0070] The outer surface of the wall panel W is fixedly connected with a plurality of vertically extending barrier members 9, and the barrier members 9 include a barrier fitting portion 91 fixed to the outer surface of the wall panel W, and a barrier main body portion 92 integrally connected to the barrier fitting portion 91 and protruding to the outer side of the wall panel W, and a protective layer 93 made of elastic material is attached to the outer surface of the barrier main body portion 92. The barrier members 9 mainly have two functions. First, the barrier members 9 act as reinforcing ribs to enhance the overall structural strength of each wall panel W. Second, the barrier members 9 can also support the original wall to prevent the bathroom frame assembly from moving. The protective layer 93 of elastic material can prevent the barrier members 9 from directly contacting the original wall and play a buffering role.
