Description

Technical Field

[0001] The present invention relates to the technical field of decoration design,

[0002] In particular, the present invention relates to an internal corner connection structure and connection method for an assembled kitchen wall surface. 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 interior space and play a role in beautifying the decoration.

[0004] Currently, traditional kitchen decoration generally fixes wall tiles and floor tiles with cement mortar. The on-site operation has a large dust pollution, high requirements for the handicraft technology of workers, and a long decoration period. During installation, local adjustment and replacement cannot be carried out, and high requirements for the installation technology of workers, which is time-consuming and laborious, and has a high labor intensity. Therefore, the installation of kitchen wall panels now tends to be assembled to achieve the purpose of accelerating the construction efficiency and saving construction consumption.

[0005] Especially at the internal corner wall surface of the kitchen, it is more necessary to develop a new assembled wall panel internal corner connection structure. For example, the Chinese patent utility model patent CN215670679U relates to an assembled kitchen wall panel internal corner structure that is convenient for installation. The above utility model achieves the purpose of stable wall panel internal corner structure and not easily allowing the internal corner structure to burst, decompose, or be extruded and deformed when the plate body or wall surface deforms by setting a grooving unit on the first wall panel and setting a connecting plate unit, a right-angle plate unit, and an elastic cylinder unit between the first wall panel and the second wall panel. The above utility model has the following advantages: First, the internal corner reinforcement structure between the two wall panels is integrated with the installation structure of the wall panel on the wall surface, making the entire wall panel internal corner structure more stable and the installation more convenient; Second, a sealing elastic strip is provided between the two wall panels, and the wall panel is indirectly and elastically connected to the wall surface, ensuring that the wall panel internal corner structure is not easily burst, decomposed, or extruded and deformed when the wall panel itself or the wall surface deforms.

[0006] However, the above ceiling structure still has the following problems: complex structure, troublesome installation of wall panels, requiring the installation of keels first and then wall panels on the keels, not only having high requirements for installation positioning, but also being unable to absorb the cumulative error of wall panel installation, poor waterproof ability at the internal corner structure, and short service life.

[0038] Technologies, methods, and systems known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and systems should be regarded as part of the authorization specification.

[0039] Embodiment 1: As Figures 1 to 5 shown, it is merely one of the embodiments of the present invention. An internal corner connection structure for an assembled kitchen wall includes a first internal corner plate 100 provided on a wall body 400, a second internal corner plate 200 provided on the wall body 400 and perpendicular to the first internal corner plate 100, and an internal corner connector 6 for connecting the first internal corner plate 100 and the second internal corner plate 200. A reinforcing member 300 is provided at the end of the second internal corner plate 200. The reinforcing member 300 includes a reinforcing middle plate 301, a short side plate 302 provided at one end of the reinforcing middle plate 301 close to the wall body 400, and a long side plate 303 provided at one end of the reinforcing middle plate 301 away from the wall body 400. The internal corner connector 6 includes an internal corner bottom plate 61 parallel to the second internal corner plate 200, an abutting block 62 provided at one end of the internal corner bottom plate 61 close to the first internal corner plate 100 for connecting with the first internal corner plate 100, and a pressing plate 63 provided at one end of the internal corner bottom plate 61 away from the abutting block 62. The pressing plate 63 is parallel to the internal corner bottom plate 61, and at least a part of the short side plate 302 is located between the pressing plate 63 and the wall body 400.

[0040] In the present invention, the wall body 400 at the internal corner is equivalent to having two wall surfaces, namely the first wall surface and the second wall surface. The first internal corner plate 100 is installed on the first wall surface, and the second internal corner plate 200 is installed on the second wall surface. We default that the two wall bodies are vertically arranged, so the first internal corner plate 100 and the second internal corner plate 200 are also vertically arranged. The first internal corner plate 100 and the second internal corner plate 200 are connected by an internal corner connecting piece 6, and the first internal corner plate 100, the second internal corner plate 200 and the internal corner connecting piece 6 are all installed on the leveling pieces on the wall body 400. Among them, the first internal corner plate 100 is installed on the first wall surface through the first leveling piece, and the second internal corner plate 200 and the internal corner connecting piece 6 are installed on the second wall surface through the second leveling piece.

[0041] First, it is the structure of the internal corner plates (including the first internal corner plate 100 and the second internal corner plate 200). At one end of the second internal corner plate 200 close to the first internal corner plate 100, a reinforcing member 300 is provided. The reinforcing member 300 includes a reinforcing middle plate 301, a short side plate 302 provided at one end of the reinforcing middle plate 301 close to the wall body 400, and a long side plate 303 provided at one end of the reinforcing middle plate 301 far from the wall body 400. Among them, the reinforcing middle plate 301 is closely attached to the end face of the second internal corner plate 200, and the short side plate 302 and the long side plate 303 are both perpendicular to the reinforcing middle plate 301. The side of the short side plate 302 far from the long side plate 303 is flush with the side of the second internal corner plate 200 close to the second wall body 400, and the side of the long side plate 303 far from the short side plate 302 is flush with the side of the second internal corner plate 200 far from the second wall body 400.

[0042] Then, it is the structure of the internal corner connecting piece 6. The internal corner connecting piece 6 includes an internal corner bottom plate 61 arranged in parallel with the second internal corner plate 200, an abutting block 62 provided at one end of the internal corner bottom plate 61 close to the first internal corner plate 100 for connecting with the first internal corner plate 100, and a pressing plate 63 provided at one end of the internal corner bottom plate 61 far from the abutting block 62. The pressing plate 63 is arranged in parallel with the internal corner bottom plate 61, and at least a part of the short side plate 302 is located between the pressing plate 63 and the wall body 400; here, the internal corner bottom plate 61 is arranged in parallel with the second wall body, the abutting plate 62 is provided at one end of the internal corner bottom plate 61 close to the first wall body and extends towards the side far from the second wall body, the pressing plate 63 is parallel to the second wall body, and the distance between the pressing plate 63 and the second wall body is greater than the distance between the internal corner bottom plate 61 and the second wall body. This distance difference facilitates the insertion of the short side plate 302.

[0043] Moreover, a caulking block 7 is also provided at the internal corner connector 6. The caulking block 7 includes a first plate body 71 vertically arranged with respect to the first internal corner plate 100 and a second plate body 72 arranged parallel to the first internal corner plate 100. The first plate body 71 is connected to the abutting block 62 through an internal corner tape 73. At least a part of the second plate body 72 is located between the long side plate 303 and the first internal corner plate 100. The caulking block 7 is an L-shaped part, and the caulking block 7 is arranged at one end of the abutting plate 62 away from the second wall body. The first plate body 71 of the caulking block 7 is connected to the abutting block 62 through the internal corner tape 73. The second plate body 72 is arranged parallel to the first wall body and continues to extend in the direction away from the second wall body. Moreover, one side of the second plate body 72 close to the first wall body is flush with one side of the abutting block 62 close to the first wall body.

[0044] Finally, the specific steps for internal corner connection are as follows:

[0045] Before installing the internal corner plate, a first leveling part and a second leveling part need to be installed on the two wall bodies where the internal corner is located respectively and leveling is completed.

[0046] Then start the installation of the first internal corner plate 100. Install the first internal corner plate 100 on the first leveling part on the first wall body, and the first internal corner plate 100 extends to the second wall body 200 (at a certain distance from the second wall body).

[0047] Next, fix the first internal corner plate 100. At this time, install the internal corner connector 6 on the second leveling part of the second wall body. The internal corner bottom plate 61 of the internal corner connector 6 closely adheres to the outside of the second leveling part and slides towards the first wall body direction, so that one side of the abutting block 62 in the internal corner connector 6 abuts against one side of the first internal corner plate 100 away from the first wall body. At this time, install the internal corner bottom plate 61 on the second leveling part (the middle plate) through an internal corner screw 611 to complete the fixation of the first internal corner plate 100.

[0048] Then install the caulking block 7 at the end of the abutting block 62, so that the first plate body 71 of the caulking block 7 is connected to the abutting block 62 through the internal corner tape 73, and the second plate body 72 closely adheres to one side of the first internal corner plate 100 away from the first wall body.

[0049] Finally, carry out the installation of the second internal corner plate 200. Insert the second internal corner plate 200 perpendicular to the first internal corner plate 100 and towards the first internal corner plate 100 direction, so that the short side plate 302 at the end of the second internal corner plate 200 is inserted between the pressing plate 63 and the second leveling part (the middle plate), and the end of the long side plate 303 abuts against one side of the second plate body 72 away from the first internal corner plate 100 to complete the installation of the second internal corner plate 200.

[0050] During the installation process, the abutting block 62 has a certain length (i.e., extending away from the second wall), which can absorb the installation error of the first inside corner board 100. As long as the first inside corner board 100 is not too far from the second wall, the abutting board 62 can abut against the outside of the first inside corner board 100 to complete the fixed installation of the first inside corner board 100;

[0051] Similarly, the distance between the pressing board 63 and the second wall is greater than the distance between the bottom inside corner board 61 and the second wall. This distance difference facilitates the insertion of the short side board 302 and can limit the second inside corner board 200 (in the direction away from the second wall). The barrier of the second board 72 can not only limit the second inside corner board 200 (in the direction away from the first wall) but also fill the gap between the first inside corner board 100 and the second inside corner board 200, achieving a waterproof effect.

[0052] The inside corner connection structure of a prefabricated kitchen wall surface in the present invention has a simple structure and is convenient to install. The first inside corner board is fixed by the inside corner connecting piece, and the cumulative installation error of the first inside corner board can be effectively absorbed. The second inside corner board is then installed on the inside corner connecting piece, with low positioning requirements, good installation stability, and the position of the second inside corner board can be limited by the caulking block, and it can also provide good waterproof ability and a long service life.

[0053] Embodiment 2, still as Figures 1 to 5 shown, is only one of the embodiments of the present invention. On the basis of Embodiment 1, in the inside corner connection structure of a prefabricated kitchen wall surface of the present invention, the first inside corner board 100, the second inside corner board 200, and the inside corner connecting piece 6 are all connected to the wall 400 through leveling pieces. The leveling pieces (including the first leveling piece and the second leveling piece) include a keel 1 arranged on the wall 400, a movable piece 2 arranged on the keel 1, and a connecting bolt 500 for connecting the keel 1 and the movable piece 2. The keel 1 is vertically arranged, and the keel 1 includes a bottom plate 11 arranged on the wall 400 and a protruding plate 12 arranged on the bottom plate 11. The movable piece 2 includes an intermediate plate 23, a first side plate 21 arranged at the end of the intermediate plate 23 extending towards the wall 400, and a second side plate 22 arranged at one end of the intermediate plate 23 away from the first side plate 21 and extending towards the wall 400. 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.

[0054] That is, the movable member 2 is installed on the outer side of the protruding plate 12 of the keel 1, such that the middle plate 23 is located at one 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, after the tie bolts sequentially pass through the second waist holes on the first side plate 21, the first waist holes on the protruding plate 12, and the second waist holes on the second side plate 22 and are tightened at both ends, the first side plate 21 and the second side plate 22 clamp the protruding plate 12, and under the action of friction, the connection between the movable member 2 and the keel 1 is completed.

[0055] It should be noted that both the first waist hole and the second waist hole are perforations provided in a long strip shape, and the first waist hole and the second waist hole are vertically arranged. That is, the connecting bolt 500 slides in the first waist hole or the second waist hole, thereby adjusting the installation position of the movable member 2 on the keel 1; generally, the first waist hole is arranged horizontally, and the front-back adjustment of the movable member 2 (i.e., the distance from the wall body 400) can be realized, and the second waist hole is arranged vertically, 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, so that the sides of the middle plates 23 of all the movable members 2 away from the wall body 400 are aligned, and 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, with strong versatility, convenient installation, and high construction efficiency.

[0056] Embodiment 3, still as Figures 1 to 5 shown, is only one of the embodiments of the present invention. On the basis of any of the above embodiments, in the internal corner connection structure of an assembled kitchen wall of the present invention, at least a part of the short side plate 302 is located between the pressing plate 63 and the middle plate 23, and a corner screw 611 for connecting with the middle plate 23 is provided on the corner bottom plate 61.

[0057] Moreover, a protruding block 631 extending in the direction of the short side plate 302 is provided on the pressing plate 63.

[0058] Here, the number of the protruding blocks 631 is at least one, and a plurality of the protruding blocks 631 are arranged in parallel, and an adhesive is provided between two adjacent protruding blocks 631. After the adhesive solidifies, it can prevent the second internal corner plate 200 from being accidentally pulled out.

[0059] Of course, the caulking block 7 is an integrally formed elastic member, which can prevent the end of the long side plate 303 from being worn and plays a certain buffering role. The caulking block 7 is preferably a waterproof rubber member.

[0060] In addition, the internal corner connecting member 6 is an integrally formed rigid member, which ensures the fixing stability of the first internal corner plate 1090 and the second internal corner plate 200.

[0061] Example 4, as Figure 6 shown, is only one of the embodiments of the present invention. The present invention also provides a connection method for the internal corner connection structure of a prefabricated kitchen wall surface of any of the above embodiments, including the following steps:

[0062] S1: Install the first leveling member and the second leveling member on the two walls arranged at the internal corner respectively and complete leveling;

[0063] S2: Install the first internal corner plate on the first leveling member on the first wall, and the first internal corner plate extends to the second wall;

[0064] S3: Install the internal corner connecting member on the second leveling member of the second wall, so that the side of the abutting block in the internal corner connecting member away from the internal corner bottom plate abuts against the side of the first internal corner plate away from the first wall, and install the internal corner bottom plate on the middle plate of the second leveling member through internal corner screws to complete the fixation of the first internal corner plate;

[0065] S4: Install a caulking block at the end of the abutting block, so that the first plate body of the caulking block is connected to the abutting block through an internal corner tape, and the second plate body is closely attached to the side of the first internal corner plate away from the first wall;

[0066] S5: Insert the second internal corner plate perpendicular to the first internal corner plate and towards the first internal corner plate, so that the short side plate at the end of the second internal corner plate is inserted between the pressing plate and the middle plate of the second leveling member, and the end of the long side plate abuts against the side of the second plate body away from the first internal corner plate to complete the installation of the second internal corner plate.

[0067] The structure of the internal corner connection structure and the connection method of a prefabricated kitchen wall surface of the present invention is simple and convenient to install. The first internal corner plate is fixed through the internal corner connecting member, and the cumulative installation error of the first internal corner plate is effectively absorbed. The second internal corner plate is then installed on the internal corner connecting member, with low positioning requirements, good installation stability, and the position of the second internal corner plate can be limited through the caulking block, and it can also provide good waterproof ability and a long service life.

[0068] The present invention is not limited to the above specific embodiments, and the present invention can have various changes and modifications.
