[0002] In particular, the present invention relates to a butt-joint structure and a connection method for an assembled kitchen wall. Background Art

[0003] Currently, the decoration industry is developing towards industrialized modular installation. Generally speaking, wall decoration is a commonly used decoration method in interior design, which can increase the sense of hierarchy of the indoor space and play a role in beautifying the decoration.

[0004] At present, traditional kitchen decoration generally fixes wall tiles and floor tiles through cement mortar. The on-site operation has a large dust pollution, high requirements for the craftsmanship of workers, a long decoration period, and it is impossible to perform local adjustment and replacement during installation. High requirements for installation workers, time-consuming and laborious, and high labor intensity. Therefore, the installation of kitchen wall panels now prefers assembled installation to achieve the purpose of accelerating construction efficiency and saving construction consumption. For example, the Chinese patent utility model patent CN215760179U discloses an assembled kitchen wall rock board installation structure, which includes a bolt assembly. The bolt assembly includes a bolt base, a screw rod and a nut; the bolt base is used to connect with the wall, and the nut is connected to the bolt base through the screw rod; a keel, the keel is formed with a keel groove, and the keel groove is used to be connected with the nut in a snap-fit manner. The assembled kitchen wall rock board installation structure provided by the above application does not require grooving or drilling of the rock board, reduces the loss of the rock board, does not require embedded back bolts, and simplifies the process; the bolt assembly is leveled and fixed with steel nails, without drilling the wall and matching with expansion, simplifies the construction and saves working hours; the male-female buckle connection and fixing method is simple and convenient, can improve the construction efficiency and shorten the construction period; the aluminum honeycomb composite rock board, the installation of large wall panels, reduces the splicing gap, which not only makes the kitchen cleaning more convenient, but also makes the wall look better.

[0039] Embodiment 1: As Figures 1 to 5 shown, it is merely one embodiment of the present invention. A flat joint structure for an assembled kitchen wall includes a first wall panel 100, a second wall panel 200, and a flat joint member 3 for connecting the first wall panel 100 and the second wall panel 200. Reinforcing members 300 are provided at the ends of both the first wall panel 100 and the second wall panel 200. The reinforcing member 300 includes a reinforcing middle plate 301 and reinforcing side plates 302 provided at the ends of the reinforcing middle plate 301. The flat joint member 3 includes a flat joint bottom plate 31. A pressing plate 32 for connecting with the reinforcing side plate 302 of the first wall panel 100 is provided at the end of the flat joint bottom plate 31. An abutting plate 33 for connecting with the reinforcing middle plate 301 of the second wall panel 200 is provided at the end of the flat joint bottom plate 31 away from the pressing plate 32. The pressing plate 32 is arranged parallel to the flat joint bottom plate 31, and the abutting plate 33 is arranged perpendicular to the flat joint bottom plate 31.

[0040] In the present invention, a leveling member is first installed on the wall body 400 for leveling, and then the first wall panel 100 and the second wall panel 200 are installed on the leveling member, and the flat joint of the first wall panel 100 and the second wall panel 200 is completed through the flat joint member 3 between the first wall panel 100 and the second wall panel 200.

[0041] First, it is the structure of the first wall panel 100 and the second wall panel 200. Reinforcing members 300 are provided at the ends of the first wall panel 100 and the second wall panel 200. The reinforcing member 300 includes a reinforcing middle plate 301 and reinforcing side plates 302 provided at the ends of the reinforcing middle plate 301. In fact, there are two reinforcing side plates 302, which are respectively arranged at both ends of the reinforcing middle plate 301, forming a C-shaped structure. The two reinforcing side plates 302 are arranged in parallel. The length of the outer reinforcing side plate 302 (the side away from the wall body 400) is greater than the length of the inner reinforcing side plate 302 (the side close to the wall body 400). After the first wall panel 100 and the second wall panel 200 are connected, the outer reinforcing side plate 302 is close to form a wall joint, and a decorative panel layer can be provided on the outer sides of the first wall panel 100 and the second wall panel 200.

[0042] Then, it is the structure of the flat joint member 3. The flat joint member 3 includes a flat joint bottom plate 31. A pressing plate 32 for connecting with the reinforcing side plate 302 of the first wall panel 100 is provided at the end of the flat joint bottom plate 31. A resisting plate 33 for connecting with the reinforcing middle plate 301 of the second wall panel 200 is provided at the end of the flat joint bottom plate 31 away from the pressing plate 32. The pressing plate 32 is arranged in parallel with the flat joint bottom plate 31, and the resisting plate 33 is arranged perpendicular to the flat joint bottom plate 31.

[0043] Here, a first tape 303 for connecting with the pressing plate 32 is provided on the reinforcing side plate 302 of the first wall panel 100; a second tape 304 for connecting with the resisting plate 33 is provided on the reinforcing middle plate 301 of the second wall panel 200. Through the structures of the first tape 303 and the second tape 304, not only can the first wall panel 100 and the second wall panel 200 be connected, but also waterproofing can be achieved to prevent water from seeping through the joint to the inner sides of the first wall panel 100 and the second wall panel 200.

[0044] Finally, the flat joint steps of the first wall panel 100 and the second wall panel 200 are as follows: First, install the leveling member on the wall body 400 and complete leveling; then place the end of the first wall panel 100 with the reinforcing member 300 installed on the leveling member, and set the first tape 303 on the side of the reinforcing side plate 302 of the first wall panel 100 away from the leveling member; then install the flat joint member 3 on the leveling member through screws, so that the pressing plate 32 at the end of the flat joint bottom plate 31 of the flat joint member 3 presses the side of the reinforcing side plate 302 of the first wall panel 100 away from the leveling member; then set the second tape 304 on the reinforcing middle plate 301 of the second wall panel 200; finally, move the second wall panel 200 towards the first wall panel 100 until the reinforcing middle plate 301 of the second wall panel 200 is connected to the resisting plate 33 at the end of the flat joint bottom plate 31 away from the pressing plate 32 through the second tape 304, completing the flat joint of the first wall panel 100 and the second wall panel 200.

[0045] Moreover, the first tape 303 is an EVA single-sided tape, and the second tape 304 is an MS adhesive. During use, first install the first tape 303 on the (inner) reinforcing side plate 302 at the end of the first wall panel 100. When installing the flat joint 3, the left and right installation positions of the flat joint 3 and the first tape 303 can be adjusted first, and then the pressing plate 32 is pressed down and maintained for a period of time until the first tape 303 solidifies. Similarly, the second tape 304 is first installed on the reinforcing middle plate 301 at the end of the second wall panel 200. When installing the second wall panel 200, first align the front and back positions of the second wall panel 200 (i.e., the distance from the wall body 400), and then connect the second tape 304 with the abutting plate 33 and maintain for a period of time until the second tape 304 solidifies.

[0046] That is to say, before the first tape 303 and the second tape 304 are stably connected, the left-right and front-back relationships between the first wall panel 100 and the second wall panel 200 can be adjusted to align the first wall panel 100 and the second wall panel 200.

[0047] The flat joint structure of an assembled kitchen wall surface of the present invention has a simple structure, is convenient to install, has a high installation efficiency of wall panels, is convenient to adjust between adjacent two wall panels, is convenient to align the wall panels and the joint seams, and has good waterproof performance.

[0048] Embodiment 2, still as Figures 1 to 5 shown, which is only one embodiment of the present invention. On the basis of Embodiment 1, in the flat joint structure of an assembled kitchen wall surface of the present invention, the flat joint 3 is connected to the wall body 400 through a leveling member. The leveling member includes a keel 1 arranged on the wall body 400, a movable member 2 arranged on the keel 1, and a connecting bolt 500 for connecting the keel 1 and the movable member 2. The keel 1 is vertically arranged, and the keel 1 includes a bottom plate 11 arranged on the wall body 400 and a protruding plate 12 arranged on the bottom plate 11. The movable member 2 includes an intermediate plate 23, a first side plate 21 extending towards the wall body 400 at the end of the intermediate plate 23, and a second side plate 22 extending towards the wall body 400 at one end of the intermediate plate 23 away from the first side plate 21. At least a part of the protruding plate 12 is located between the first side plate 21 and the second side plate 22. A first waist-shaped hole is arranged on the protruding plate 12, and second waist-shaped holes are arranged on both the first side plate 21 and the second side plate 22. The connecting bolt 500 is a tension bolt, and at least a part of the connecting bolt 500 is located in the first waist-shaped hole and the second waist-shaped hole.

[0049] That is, the movable member 2 is installed on the outer side of the protruding plate 12 of the keel 1, such that the intermediate plate 23 is located at the end of the protruding plate 12 away from the bottom plate 11, and the first side plate 21 and the second side plate 22 are respectively located on both sides of the protruding plate 12. Then, the tension bolts pass through the second waist-shaped holes on the first side plate 21, the first waist-shaped holes on the protruding plate 12, and the second waist-shaped holes on the second side plate 22 in sequence and are tightened at both ends, such that the first side plate 21 and the second side plate 22 clamp the protruding plate 12. Under the action of friction, the connection between the movable member 2 and the keel 1 is completed.

[0050] It should be noted that both the first waist-shaped hole and the second waist-shaped hole are perforations provided in a long strip shape, and the first waist-shaped hole and the second waist-shaped hole are vertically arranged. That is, the connection bolt 500 slides in the first waist-shaped hole or the second waist-shaped hole, thereby adjusting the installation position of the movable member 2 on the keel 1. Generally, the first waist-shaped hole is horizontally arranged, and the front-back adjustment of the movable member 2 (i.e., the distance from the wall body 400) can be realized. The second waist-shaped hole is vertically arranged, and the up-down adjustment of the movable member 2 (i.e., the distance from the ground) can be realized. The up-down and front-back adjustment of the movable member 2 is completed, such that the sides of the intermediate plates 23 of all the movable members 2 away from the wall body 400 are aligned. The kitchen wall tiles installed on the movable member 2 can be leveled and adjusted. Multiple keels 1 can be installed on the wall body 400, and multiple movable members 2 can be installed on each keel 1. It has strong versatility, is convenient to install, and has high construction efficiency.

[0053] Here, the end of the waterproof tape 313 is provided with extrusion locking teeth 315, and the inner side walls of both the first clamping groove 314 and the second clamping groove 331 are provided with connecting locking teeth 316 for cooperating with the extrusion locking teeth 315.

[0054] In this way, a waterproof tape 313 is arranged outside the flat joint screw 311 on the flat joint bottom plate 31, so that one end of the waterproof tape 313 is extruded into the first clamping groove 314 on the flat joint bottom plate 31 through the tooth clamping structure, and the other end of the waterproof tape 313 is extruded into the second clamping groove 331 on the abutting plate 33 through the tooth clamping structure.

[0055] Of course, the upper and lower ends of the waterproof tape 313 are closely attached to the sides of the flat joint bottom plate 31 and the abutting plate 33, ensuring that the periphery of the flat joint screw 311 is fully enclosed, preventing water seepage and leakage, and ensuring the waterproof performance.

[0056] Moreover, after the first wall panel 100 and the second wall panel 200 are connected, the flat joint seam between the first wall panel 100 and the second wall panel 200 can be leveled by a tile leveler 600, as Figure 5 shown.

[0057] Finally, the pressing plate 32 is connected to the end of the flat joint bottom plate 31 through a transition plate 321, and the length of the transition plate 321 is not less than the thickness of the strengthening edge plate 302.
