Description

Technical Field

[0001] This utility model belongs to the field of prefabricated modular wall panel technology, and in particular relates to a U-shaped tenon joint panel splicing structure. Background Technology

[0002] Prefabricated construction involves disassembling and assembling the main frame and wall components of a building, significantly accelerating construction speed. Wall components are produced in a standardized, assembly-line production process in a factory, reducing external environmental interference and ensuring more uniform and consistent quality. These components also include interior decorative panels for installation inside the building, eliminating the need for painting and reducing finishing time. Traditional splicing panel structures use wavy tenon joints with slotted joints, and the clips are installed outside the groove, making grooving difficult and requiring a high balance of toughness and strength in the panels, resulting in relatively complex installation. Therefore, a U-shaped tenon joint panel splicing structure is needed to solve these technical problems. Summary of the Invention

[0003] This utility model addresses the technical problems existing in the prior art by providing a U-shaped tenon joint plate splicing structure.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A U-shaped tenon joint plate splicing structure includes a guard plate and a clip. The left and right ends of the guard plate are splicing ends. One splicing end is provided with a first protrusion and a first recess, and the other splicing end is provided with a second protrusion, a third protrusion, and a second recess. The third protrusion is longer than the second protrusion. The clip includes an outer plate, on which a right-angle clip is vertically fixed. The second protrusion is inserted into the inner side of the right-angle clip, and the front and rear sides of the second protrusion are respectively attached to the right-angle clip and the outer plate.

[0005] In a preferred embodiment, the second notch is located between the second protrusion and the third protrusion, the front and rear sides of the guard plate are parallel, and the sum of the thicknesses of the first protrusion and the third protrusion is the same as the overall thickness of the guard plate.

[0006] As a preferred embodiment, the inner and outer corners of the first protrusion, the first recess, the second protrusion, the third protrusion, and the second recess are all right angles.

[0007] As a preferred embodiment, the outer plate is provided with a first protrusion and a second protrusion, and the first protrusion and the second protrusion are respectively located on both sides of the right-angle plate, and the protrusion direction of the first protrusion and the second protrusion is opposite to the direction of the right-angle plate.

[0008] As a preferred embodiment, the card is made of metal.

[0009] As a preferred embodiment, the inner angle of the first notch is a right angle.

[0010] As a preferred embodiment, the protective panel is made of wood.

[0011] As a preferred embodiment, both the first protrusion and the second protrusion are in the shape of an isosceles trapezoid, and the protrusion depths of the first protrusion and the second protrusion are the same.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This utility model features a first protrusion and a first recess on one splicing end, and a second protrusion, a third protrusion, and a second recess on the other splicing end. The internal and external angles of the first protrusion, first recess, second protrusion, third protrusion, and second recess are all right angles. The structure is simple and easy to cut and groove. During splicing, the clips are first fixed to the wall. The first protrusion end of one of the guard plates is placed against the back of the right-angle clip. Then, the second protrusion end of the other guard plate is inserted into the right-angle clip. After insertion, the third protrusion limits the first protrusion, thus forming a stable connection structure. The operation is simple and installation is convenient. This utility model also improves the stability of the tenon joint splicing; it is compatible with various embedded trim lines, and improves the panel system of prefabricated modular wall panels.

[0015] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0016] In the description of this utility model, it should be understood that the terms "upper," "lower," "left," and "right," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or a specific orientational structure and operation. Therefore, they should not be construed as limitations on this utility model. Furthermore, "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "multiple" means two or more.

[0017] Please see Figures 1 to 3 As shown, this embodiment of the utility model provides a U-shaped tenon joint structure for splicing boards, including a guard plate 2 and a clip 3. The left and right ends of the guard plate 2 are splicing ends. One splicing end is provided with a first protrusion 21 and a first recess 22, and the other splicing end is provided with a second protrusion 23, a third protrusion 24, and a second recess 25. The third protrusion 24 is longer than the second protrusion 23, and the second recess 25 is located between the second protrusion 23 and the third protrusion 24, thus forming a U-shaped structure, and the inner sides of the recess are all right angles. The front and rear sides of the guard plate 2 are parallel, and the sum of the thicknesses of the first protrusion 21 and the third protrusion 24 is the same as the overall thickness of the guard plate 2. The inner angle of the first recess 22 is a right angle, which facilitates cutting operations. The guard plate 2 is preferably made of wood.

[0018] Please see Figures 1 to 3 As shown, card 3 includes an outer plate 31, on which a right-angled plate 34 is vertically fixed. A second protrusion 23 is inserted into the inner side of the right-angled plate 34, and the front and rear sides of the second protrusion 23 are respectively attached to the right-angled plate 34 and the outer plate 31. The outer plate 31 is provided with a first protrusion 32 and a second protrusion 33, which are located on both sides of the right-angled plate 34. The protruding directions of the first protrusion 32 and the second protrusion 33 are opposite to the direction of the right-angled plate 34.

[0019] Specifically, in this embodiment, both the first protrusion 32 and the second protrusion 33 are isosceles trapezoidal in shape, and their protrusion depths are the same. During use, the card 3 is first fixed to the wall, and then the cards are assembled at that position. After assembly, the next position is assembled. Because the wall surface is uneven, the flat card 3 is difficult to fit snugly against the wall. To ensure installation effectiveness, the first protrusion 32 and the second protrusion 33 are positioned to keep the card 3 a certain distance from the wall, thus avoiding the influence of the wall surface's flatness and ensuring the card 3's flatness during installation. Installation is based on the plane of the card 3. The card 3 is made of metal, preferably stainless steel.

[0020] During assembly, first fix card 3 to the wall. Place the first protrusion 21 of one of the guard plates 2 against the back of the right-angle plate 34. Then insert the second protrusion 23 of the other guard plate 2 into the right-angle plate 34. After insertion, the third protrusion 24 limits the position of the first protrusion 21, thus forming a stable connection structure. Furthermore, the installation order of the guard plates on both sides of the right-angle plate 34 is not limited. For example, one guard plate 2 can be inserted first, with its second protrusion 23 inserted, and then the first protrusion 21 of the other guard plate 2 against the back of the right-angle plate 34. The specific order can be determined according to the left-right installation sequence of the guard plates.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
