Description

Technical Field

[0001] This utility model relates to the field of decoration and renovation technology, specifically to a connection structure for prefabricated dry-laid flooring. Background Technology

[0002] Traditional decoration methods have been prevalent in China for a long time. They involve many on-site steps, various trades, and heavy reliance on manual labor, resulting in problems such as long time consumption and difficulty in guaranteeing quality. They also involve large amounts of materials used in the first decoration, high transportation costs, and huge losses caused by secondary decoration.

[0003] In recent years, with the rapid development of the decoration and renovation industry, prefabricated decoration, as an important component, has received widespread attention. Dry tiling construction, as an increasingly popular decoration tiling method, is gradually gaining popularity due to its efficient tiling technology and convenient maintenance procedures.

[0004] Chinese utility model patent application CN219138239U discloses a composite panel structure with pre-set pipelines, including a composite panel and connectors for connecting the composite panel. The composite panel includes a brick layer and a support layer bonded to the bottom of the brick layer. The support layer includes a honeycomb panel and a first buffer pad bonded to the bottom of the honeycomb panel. It features convenient assembly and strong load-bearing capacity. However, because the multi-layer structure of the composite panel is completely cured and bonded together, in order to meet the leveling requirements of different ground surfaces, the thickness of the buffer pad is greater than the height difference of the rough ground (i.e., the difference between the highest and lowest points of the rough ground). When a person steps on the panel, the excessively thick buffer pad will bend and deform under the person's weight, causing the panel to sink in some areas, giving the person a feeling of sinking. Moreover, after a period of use, in areas with frequent human activity, the buffer pad is more likely to be compacted, and the floor is prone to sinking.

[0005] In view of this, the applicant has conducted in-depth research on the above-mentioned issues, which led to this case. Utility Model Content

[0017] The utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] The terms "first," "second," etc., used in the specification, claims, and drawings of this utility model are used to distinguish different objects, rather than to describe a specific order.

[0019] like Figures 1-7 As shown, this embodiment provides a connection structure for prefabricated dry-laid flooring, including a horizontally arranged square frame 10, positioning and leveling components 20, and support blocks 30. The positioning and leveling components 20 are located at the four corners of the square cross-section of the square frame 10, and the support blocks 30 are located at the four sides of the square cross-section of the square frame 10. In this embodiment, the square frame 10 is a nylon square frame, which gives the square frame 10 a certain degree of elasticity.

[0020] Each positioning and leveling component 20 includes a base 21, a threaded post 22 integrally connected to the base 21 and arranged perpendicularly to the base 21, and a circular adjusting plate 23 spirally connected to the threaded post 22 and arranged parallel to the base 21. The top of each of the four corner areas of the square frame 10 is provided with a fan-shaped recess. The center of the fan-shaped recess in its cross-section is located on the four corner edges of the square frame 10. Each circular adjusting plate 23 is partially located within its corresponding fan-shaped recess. The upper surface of the square frame 10 is flush with the upper surface of each circular adjusting plate 23. In the same positioning and leveling component 20, two arc-shaped blocks 24 are provided on the side of the circular adjusting plate 23 facing the base 21. Blocks 24 are arranged symmetrically around the axis of the circular adjusting plate 23. The axes of the side walls of the two arc-shaped blocks 24 coincide with the axis of the circular adjusting plate 23. On the side of the two arc-shaped blocks 24 that are far apart from each other, a first slot 25 is provided, penetrating both ends of its circumference. Each first slot 25 penetrates upwards through the upper end face of the corresponding arc-shaped block 24. It should be noted that the upper end face of the arc-shaped block 24 is the side face of the side where the arc-shaped block 24 and the circular adjusting plate 23 are connected. An arc-shaped recess 11 is provided at the bottom of each fan-shaped recess, with both ends of each arc-shaped recess 11 extending to the two side walls of the square frame 10. Each arc-shaped block 24 is inserted into its corresponding arc-shaped recess 11.

Each arc-shaped sink 11 has a first locking block 12 on the sidewall closest to the center of the square frame 10. The upper end face of the first locking block 12 is flush with the bottom face of the fan-shaped sink. Each first locking block 12 is engaged in the corresponding first locking groove 25. Before use, the factory first laminates the honeycomb board onto the buffer pad to form a composite structure. During installation, first place the four bases 21 on the rough ground, place the composite structure in the space enclosed by the four positioning and leveling parts, place the square frame 10 on the composite structure, and then screw the circular adjusting plate 23 onto the corresponding threaded post 22, so that the square frame The first locking block 12 of the square frame 10 engages with the corresponding first locking slot 25 to complete the positioning of the square frame 10. Then, the panels are laid, with the four corners of the panels abutting against the circular adjustment plate 23. The four panels are then spliced ​​together around the same positioning and leveling component 20 to complete the full paving of the ground. With the square frame 10, positioning and leveling component 20, and support block 30, when a person steps on the panel, the person's weight will exert pressure on the panel, which will then be transmitted to the square frame 10. The square frame 10 will transmit the pressure to the support block 30, and the panel will be effectively supported. When stepping on the panel, the person will not feel sinking, and the panel will not easily sink after long-term use.

The first end of the first connecting plate 42 is connected to the second end of the first connecting plate 42 by a snap fastener. The second end of the second connecting plate 43 is connected to the first end of the L-shaped plate 41 of another frame assembly 40 by a snap fastener. This arrangement allows the square frame 10 to be disassembled into multiple frame assemblies 40. The frame assembly 40 can be disassembled into an L-shaped plate 41, a first connecting plate 42, and a second connecting plate 43. The second connecting plate 43 can be added or removed according to the actual panel requirements, making it suitable for different types of panels and with a relatively wide range of applications.
