[0002] In the field of building decoration and interior design, gypsum board is widely used in the construction of base layers such as walls and ceilings due to its advantages such as light weight, good sound and heat insulation performance and convenient construction. In actual construction, multiple gypsum boards are usually spliced ​​together to cover a large area.

[0003] The joints between the boards often become the weak points of the overall structure. Currently, the common practice is to fill the joints of gypsum boards with putty to fill the gaps and enhance the connection and aesthetics between the boards.

[0004] However, it still has shortcomings in long-term use. Putty can only seal the gaps and cannot effectively fix and limit the two plasterboards. When the boards are displaced relative to each other due to temperature changes or vibration, the putty is prone to cracking due to the force of the pull, resulting in gaps and affecting the stability and aesthetics of the structure. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a gypsum board joint crack prevention structure, which aims to improve the problem in the prior art where putty can only seal the gaps in the gypsum board joints and cannot effectively fix the board body, resulting in putty cracking when the board body is displaced by temperature changes or vibration, affecting the structural stability and aesthetics.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a gypsum board joint anti-cracking structure, comprising a board body, wherein a butt assembly is provided on the outer wall of the board body, and a protective assembly is provided on the outer wall of the board body; The docking assembly includes an insert plate, which is fixedly connected to the left surface of the plate body.

A base plate is fixedly connected to the right surface of the plate body below the positioning plate. A limit groove is formed on the upper surface of the base plate. A slot is formed at the top of the left surface of the insert plate.

[0007] As a further description of the above technical solution: The protective component includes a protective plate, with baffles fixedly connected to both the front and rear ends of the lower surface of the protective plate, slots provided at the four corners of both the upper and lower surfaces of the plate, and insert rods fixedly connected to the four corners of the lower surface of the protective plate.

[0008] As a further description of the above technical solution: The left and right ends of the lower surface of the limiting plate are both set as arc surfaces, and the left end of the lower surface of the insert plate is set as an arc surface.

[0009] As a further description of the above technical solution: The right end of the lower surface of the positioning plate is set as an arc surface, and the positioning plate is inserted into the inner wall of the slot.

[0010] As a further description of the above technical solution: The insert plate is inserted into the gap between the positioning plate and the base plate.

[0011] As a further description of the above technical solution: The limiting groove is formed as a trapezoidal platform that is wider at the top and narrower at the bottom, and the limiting plate is inserted into the inner wall of the limiting groove.

[0012] As a further description of the above technical solution: The insertion rod is inserted into the inner wall of the slot.

[0013] As a further description of the above technical solution: The protective plate, baffle, and insert rod are each provided in two sets, and the two sets of the protective plate, baffle, and insert rod are symmetrically distributed vertically around the center line of the plate.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the cooperation of the docking components can form a limit between the boards.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figure 1 This utility model provides an embodiment of a gypsum board joint crack prevention structure, including a board body 1, which is gypsum board, a prior art technology that can be implemented by those skilled in the art. As it is prior art, it will not be described in detail in this case. The outer wall of the board body 1 is provided with a butt joint component 2, which can connect adjacent boards 1 together and prevent displacement between boards 1. The outer wall of the board body 1 is provided with a protective component 3, which can wrap the butt joint component 2, enhance the tightness of the connection, reduce the gap at the joint, and enhance the aesthetics.

[0020] Reference Figures 1-3 The docking assembly 2 includes an insert plate 21, which is fixedly connected to the left surface of the plate 1. A limiting plate 22 is fixedly connected to the lower surface of the insert plate 21. The limiting plate 22 is used to limit the plate 1 and to restrain the lateral pulling force. A positioning plate 23 is fixedly connected to the right surface of the plate 1. A base plate 24 is fixedly connected to the right surface of the plate 1 below the positioning plate 23. The gap between the positioning plate 23 and the base plate 24 matches the thickness of the insert plate 21. A limiting groove 25 is opened on the upper surface of the base plate 24. The limiting groove 25 matches the limiting plate 22. A slot 26 is opened at the top of the left surface of the insert plate 21.

[0021] Reference Figures 1-3The lower surface of the limiting plate 22 has curved ends on both the left and right sides, and the lower surface of the insert plate 21 has a curved left end. The curved surfaces on the limiting plate 22 and the insert plate 21 can prevent obstruction when the insert plate 21 rotates and aligns. The lower surface of the positioning plate 23 has a curved right end, which can provide guidance for the alignment of the insert plate 21. The positioning plate 23 is inserted into the inner wall of the slot 26, which can block the top of the insert plate 21 and prevent the insert plate 21 from coming out. The insert plate 21 is inserted into the gap between the positioning plate 23 and the base plate 24. There are gaps between the three parts, but the gaps are small and can cause obstruction. However, the putty can fill the gaps later. During installation, the insert plate 21 needs to be inserted into the gap between the positioning plate 23 and the base plate 24 with the left side lower and the right side higher. When the insertion is completed, the insert plate 21, the positioning plate 23 and the base plate 24 will remain horizontal. The limiting groove 25 is opened as a trapezoid with the upper part wider and the lower part narrower. The limiting plate 22 is inserted into the inner wall of the limiting groove 25, which can provide lateral limiting between the insert plate 21 and the base plate 24 and can resist tension.

[0022] Reference Figures 1-3 The protective component 3 includes a protective plate 31. Both the front and rear ends of the lower surface of the protective plate 31 are fixedly connected to baffles 32. The side of the baffles 32 closest to the plate 1 contacts the insert plate 21, the positioning plate 23, the bottom plate 24, and the limiting plate 22. Slots 34 are provided at the four corners of the upper and lower surfaces of the plate 1. Insert rods 33 are fixedly connected at the four corners of the lower surface of the protective plate 31. The slots 34 and the insert rods 33 fit together. The bottom end of the insert rods 33 is arc-shaped, which can provide guidance. The insert rods 33 are inserted into the inner wall of the slots 34, which can connect adjacent plates 1 and provide lateral tensile resistance. There are two sets of protective plates 31, baffles 32, and insert rods 33. The two sets of protective plates 31, baffles 32, and insert rods 33 are symmetrically distributed vertically around the center line of the plate 1. The baffles 32 and the protective plate 31 can cover the insert plate 21, the positioning plate 23, the bottom plate 24, and the limiting plate 22, reducing the exposed gaps.

[0023] Working principle: During actual installation, one of the plates 1 is first tilted, and its left-side insert plate 21 is aligned with the gap between the right-side positioning plate 23 and the base plate 24 of the other plate 1. Then, the insert plate 21 is moved to the left, and while moving to the left, the insert plate 21 is gradually adjusted to be horizontal. During installation, the curved surfaces on the positioning plate 23, the limiting plate 22, and the insert plate 21 provide guidance and avoid obstruction. When the insert plate 21, the positioning plate 23, and the base plate 24 are in a horizontal state, the positioning plate 23... It will be inserted into the slot 26. The positioning plate 23 will block the top of the insertion plate 21, and the bottom plate 24 will block the bottom of the insertion plate 21 to prevent the insertion plate 21 from shifting longitudinally. This can ensure the longitudinal level between adjacent plates 1. The limiting plate 22 will also be inserted into the limiting groove 25 to limit the transverse position between the insertion plate 21 and the bottom plate 24, providing anti-tension effect. This can prevent the gap between adjacent plates 1 from changing and prevent the joint of plates 1 from cracking. Then, putty is filled into the gap.

[0024] When the putty filling is completed, insert the rod 33 on the protective plate 31 and the slot 34 on the plate 1. When the insertion is completed, the protective plate 31 and the baffle 32 will cover the insert plate 21, the limiting plate 22, the positioning plate 23, and the bottom plate 24, reducing the exposed gaps and improving the aesthetics. Furthermore, the insertion of the rod 33 and the slot 34 can further enhance the lateral tensile strength and prevent cracking at the joint of the plate 1.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
