[0005] Therefore, developing a new type of floor connecting structure to improve the stability and reliability of floor connection, while reducing installation cost and environmental impact, has become an important research direction of the current floor industry.

[0006] The utility model discloses a floor connecting structure can improve the connecting stability of adjacent floor, can effectively prevent loosening and deformation, improve sealing performance, prolong service life, and installation is simple and quick, and cost is reduced.

[0007] A floor connecting structure is arranged on the circumferential side of a floor body, and adjacent floor bodies are connected to each other through the floor connecting structure; the floor connecting structure comprises a first connecting part, a second connecting part and a third connecting part extending outward in a horizontal direction from the side of the floor body, and the first connecting part, the second connecting part and the third connecting part are arranged in sequence from bottom to top; when two adjacent floor bodies are butted, the first connecting part of each forms a planar fitting structure abutting against each other, the second connecting part of each forms an adhesive injection cavity with a predetermined volume between the opposite surfaces, and the third connecting part of each forms an adhesive injection channel communicating with the adhesive injection cavity; the adhesive injection cavity is filled with an adhesive which forms an adhesive layer after solidification, and the cross-sectional area of the adhesive injection channel is smaller than the maximum cross-sectional area of the adhesive injection cavity.

[0008] The floor connecting structure is arranged on the circumferential side of the floor body, and is used for realizing stable connection between adjacent floor bodies. The floor connecting structure comprises a first connecting part, a second connecting part and a third connecting part which extend outward from the side of the floor body in the horizontal direction. When the two adjacent floor bodies are docked, the first connecting part of each floor body forms a planar matching structure which abuts against each other. The planar matching structure can provide good initial positioning and supporting effect, and ensure the stability of the floor when it is initially docked. Meanwhile, the second connecting part of each floor body forms a glue injection cavity with a predetermined volume between the opposite surfaces, which provides space for subsequent adhesive filling. The third connecting part of each floor body forms a glue injection channel which communicates with the glue injection cavity, so as to facilitate accurate injection of the adhesive into the glue injection cavity. The glue injection cavity is filled with adhesive which can form an adhesive layer after solidification. The adhesive can tightly bond the adjacent floor bodies together after solidification, and further enhances the firmness and reliability of the floor connection. In addition, the cross-sectional area of the glue injection channel is designed to be smaller than the maximum cross-sectional area of the glue injection cavity. Such design helps to control the flow direction and flow rate of the adhesive, prevents leakage or excessive diffusion of the adhesive during injection, and ensures that the adhesive can fully fill the glue injection cavity to form a uniform and stable adhesive layer. Through the planar matching structure of the first connecting part and the adhesive layer formed by the adhesive, the adjacent floor bodies are not only mechanically connected, but also chemically bonded, which greatly enhances the stability of the floor connection and effectively prevents problems such as loosening and deformation of the floor during use. The communication design of the glue injection channel and the glue injection cavity, as well as the structure that the cross-sectional area of the glue injection channel is smaller than the maximum cross-sectional area of the glue injection cavity, can accurately control the injection amount and flow path of the adhesive, ensure that the adhesive can accurately fill the glue injection cavity, and avoid problems such as unstable connection or reduced installation precision caused by improper injection of the adhesive. The adhesive layer formed after solidification of the adhesive can effectively fill the small gaps between the floor bodies, improve the sealing performance of the floor connection, prevent water, dust and other substances from entering the floor, and prolong the service life of the floor. The design of the floor connecting structure makes the installation process of the floor more simple and convenient. Only the adjacent floor bodies need to be docked and the adhesive needs to be injected through the glue injection channel to complete the connection. No complex installation tools and tedious installation steps are required, which greatly improves the installation efficiency and reduces the installation cost. When laying the floor, especially for irregular-shaped floors such as regular hexagons and rhombuses, the floor connecting structure exhibits high applicability. Due to process limitations or material properties, etc., it is often difficult to avoid slight fluctuations in size and angle during the production and manufacturing process of such irregular-shaped floors.The connection structure can effectively deal with the fluctuations due to its unique design, accurately realize the close splicing between the floors during the construction process, greatly reduce the risk of gap generation or splicing failure caused by size and angle problems, ensure the flatness and aesthetics of the floor laying, improve the construction efficiency, reduce material loss and rework during the construction process, and provide strong technical support for the wide application of special-shaped floors.

[0009] Preferably, the abutting surface of the first connecting part is a flat surface, and the first connecting parts of the adjacent floor bodies are in surface contact.

[0010] The flat abutting surface can ensure the tightness and stability of the two floor bodies during abutting, avoid the gap and looseness problems caused by uneven surface, and improve the overall structural stability of the floor. Compared with point contact or line contact, the surface contact mode can more evenly distribute the pressure, reduce stress concentration, and effectively prevent deformation or damage of the floor due to excessive local stress during use. The flat abutting surface also helps to improve the installation accuracy of the floor, make the floor surface more flat and beautiful, and improve the overall decorative effect.

[0011] Preferably, the surface of the second connecting part is provided with at least one inclined surface, and the glue injection cavity formed between the inclined surfaces of the adjacent floor bodies is in a gradually expanding shape.

[0012] The setting of the inclined surface makes the shape of the glue injection cavity gradually expand from small to large, which is beneficial to the smooth filling of the adhesive in the entire cavity during injection, avoiding the problems of poor flow or incomplete filling of the adhesive caused by sudden change of cavity shape. The gradually expanding glue injection cavity can form a more uniform adhesive layer after the adhesive solidifies, enhance the bonding strength between the floor bodies, and improve the reliability of the floor connection. This design can also effectively reduce the resistance of the adhesive during injection, reduce the injection pressure, and thus reduce the wear and tear of the equipment and energy consumption, improving the installation efficiency.

[0013] Preferably, the depth of the glue injection channel is 1 / 3-1 / 2 of the width of the glue injection channel.

[0014] The ratio of the depth and width of the glue injection channel can effectively control the flow speed and filling effect of the adhesive, avoid the problems of too fast or too slow flow of the adhesive caused by too deep or too shallow channel, and thus ensure that the adhesive can be uniformly filled into the glue injection cavity. This ratio design can also reduce the resistance of the adhesive during injection, reduce the injection pressure, improve the injection efficiency, and reduce the wear and tear of the equipment and energy consumption. The ratio of the depth and width of the glue injection channel can also effectively prevent the leakage or excessive diffusion of the adhesive during injection, ensure that the adhesive can be accurately filled into the glue injection cavity, and improve the sealing performance and reliability of the floor connection.

[0015] Preferably, the glue cavity and the glue channel are filled with adhesive.

[0016] The sufficient filling of the adhesive can ensure that the connection between the floor bodies is more firm and stable, effectively preventing the problem of insecure connection caused by insufficient filling of the adhesive. The adhesive that fills the glue cavity and the glue channel can form a uniform adhesive layer after curing, enhancing the sealing performance of the floor, preventing moisture, dust and other substances from entering the interior of the floor, and prolonging the service life of the floor. This design can also improve the installation accuracy of the floor, making the surface of the floor more flat and beautiful, and improving the overall decorative effect.

[0017] Preferably, the adhesive is an epoxy resin sealant.

[0018] The epoxy resin sealant has excellent adhesive performance and durability, and can form a firm adhesive layer after curing, effectively enhancing the connection strength between the floor bodies.

[0019] Preferably, the ratio of the maximum cross-sectional area of the glue cavity to the cross-sectional area of the glue channel is 1.1:1-10:1.

[0020] The ratio of the maximum cross-sectional area of the glue cavity to the cross-sectional area of the glue channel can effectively control the flow speed and filling effect of the adhesive, ensuring that the adhesive can be uniformly filled into the glue cavity, and avoiding the problem of too fast or too slow flow of the adhesive due to improper ratio. This ratio design can also reduce the resistance of the adhesive during injection, reduce the injection pressure, improve the injection efficiency, and reduce the wear and energy consumption of the equipment. The ratio of the maximum cross-sectional area of the glue cavity to the cross-sectional area of the glue channel can also effectively prevent the adhesive from leaking or excessive diffusion during injection, ensuring that the adhesive can be accurately filled into the glue cavity, and improving the sealing performance and reliability of the floor connection.

[0021] Preferably, the first connecting part, the second connecting part and the third connecting part are integrally manufactured by a co-extrusion molding process.

[0022] The first connecting part, the second connecting part and the third connecting part are integrally manufactured by a co-extrusion molding process. The co-extrusion molding process can ensure that the first connecting part, the second connecting part and the third connecting part are highly unified in material and structure, forming a whole, thereby significantly improving the stability and reliability of the floor connection structure. The integrally manufactured process reduces the assembly steps between parts, avoids the problem of loose connection caused by improper assembly or long-term use, and further enhances the firmness of the floor connection.

[0023] A type of flooring includes a flooring connection structure as described above, and a flooring body. The flooring connection structure and the flooring body are integrally manufactured using a co-extrusion molding process. The co-extrusion molding process can improve production efficiency, reduce production costs, and simultaneously reduce material waste and energy consumption, exhibiting good economic and environmental benefits.

[0024] The advantages of this utility model compared to the prior art are:

[0025] This utility model's floor connection structure improves the stability of adjacent floorboards, effectively preventing loosening and deformation, enhancing sealing performance, and extending service life. It also offers simple and quick installation, reducing costs. This connection structure is particularly suitable for irregularly shaped floorboards such as hexagons and rhombuses. During the manufacturing process of these irregularly shaped floorboards, slight fluctuations in size and angle are often unavoidable due to process limitations or material properties. This connection structure, with its unique design, effectively addresses these fluctuations, achieving precise and tight splicing between floorboards during construction. This significantly reduces the risk of gaps or misjoint splicing caused by size and angle issues, ensuring the flatness and aesthetics of the flooring installation. It also improves construction efficiency, reduces material waste and rework during construction, and provides strong technical support for the widespread application of irregularly shaped floorboards.

[0034] The technical solutions in the application will be described below in conjunction with the drawings. Embodiment 1

[0035] The embodiment provides a floor, which comprises a floor body 1 and a floor connecting structure, the floor connecting structure is arranged on the circumferential side surface of the floor body 1, and is used for realizing stable connection between adjacent floor bodies 1. The specific structure is as follows:

[0036] The floor body 1 is a rectangle, and the circumferential side surface of the floor body 1 is provided with the floor connecting structure. In other embodiments, it can also be a square, a regular hexagon, a rhombus, a regular octagon and the like.

[0037] The first connecting part 2 is a first connecting part 2 extending outward from the side of the floor body 1 in the horizontal direction, and the abutting surface 21 is a flat surface. The first connecting part 2 of the adjacent floor body 1 forms a surface contact fit. The flat abutting surface can ensure the tightness and stability of the two floor bodies 1 when they are abutted, avoid the gap and looseness caused by the uneven surface, and improve the overall structural stability of the floor. Compared with point contact or line contact, the surface contact fit can more evenly distribute the pressure, reduce stress concentration, and effectively prevent the floor from deforming or damaging due to excessive local stress during use. The flat abutting surface also helps to improve the installation accuracy of the floor, making the floor surface more flat and beautiful, and improving the overall decorative effect.

[0038] The second connecting part 3 is a second connecting part 3 extending outward from the side of the floor body 1 in the horizontal direction, located above the first connecting part 2, and the surface is provided with at least one inclined surface 31. The glue injection cavity 5 formed between the inclined surfaces of the adjacent floor bodies 1 is gradually expanding. The inclined surface makes the shape of the glue injection cavity 5 gradually expand from small to large, which is beneficial to the smooth filling of the adhesive in the entire cavity during injection, and avoids the problem of poor flow or incomplete filling of the adhesive due to sudden change of cavity shape. The gradually expanding glue injection cavity 5 can form a more uniform bonding layer after the adhesive is cured, enhance the bonding strength between the floor bodies 1, and improve the reliability of the floor connection. This design can also effectively reduce the resistance of the adhesive during injection, reduce the injection pressure, and thus reduce the wear and energy consumption of the equipment, improve the installation efficiency.

[0039] The third connecting part 4 is a third connecting part 4 extending outward from the side of the floor body 1 in the horizontal direction, located above the second connecting part 3, and forms a glue injection channel 6 communicating with the glue injection cavity 5 therebetween. The depth of the glue injection channel 6 is 1 / 3-1 / 2 of the width of the glue injection channel 6. The ratio of the depth to the width of the glue injection channel 6 can effectively control the flow speed and filling effect of the adhesive, avoid the problem of too fast or too slow flow of the adhesive due to too deep or too shallow channel, and thus ensure that the adhesive can be uniformly filled into the glue injection cavity 5. This ratio design can also reduce the resistance of the adhesive during injection, reduce the injection pressure, improve the injection efficiency, and reduce the wear and energy consumption of the equipment. The ratio of the depth to the width of the glue injection channel 6 can also effectively prevent the adhesive from leaking or excessive diffusion during injection, ensure that the adhesive can be accurately filled into the glue injection cavity 5, and improve the sealing performance and reliability of the floor connection.

[0040] The ratio of the maximum cross-sectional area of the glue injection cavity 5 to the cross-sectional area of the glue injection channel 6 is 1.1:1-10:1. The ratio of the maximum cross-sectional area of the glue injection cavity 5 to the cross-sectional area of the glue injection channel 6 can effectively control the flow speed and filling effect of the adhesive, ensuring that the adhesive can be uniformly filled into the glue injection cavity 5, avoiding the adhesive flowing too fast or too slow due to improper proportion. This proportion design can also reduce the resistance of the adhesive during injection, reduce the glue injection pressure, improve the glue injection efficiency, and reduce the wear and energy consumption of the equipment. The ratio of the maximum cross-sectional area of the glue injection cavity 5 to the cross-sectional area of the glue injection channel 6 can also effectively prevent the adhesive from leaking or excessive diffusion during injection, ensuring that the adhesive can accurately fill the glue injection cavity 5, improving the sealing performance and reliability of the floor connection.

[0041] The glue injection channel 6 is formed between the third connecting part 4, and the cross-sectional area of the glue injection channel 6 is smaller than the maximum cross-sectional area of the glue injection cavity 5. The cross-sectional area of the glue injection channel 6 is designed to be smaller than the maximum cross-sectional area of the glue injection cavity 5, which helps to control the flow direction and flow of the adhesive, prevents the adhesive from leaking or excessive diffusion during injection, and ensures that the adhesive can fully fill the glue injection cavity 5 to form a uniform and stable adhesive layer.

[0042] The adhesive is filled in the glue injection cavity 5 and the glue injection channel 6, and the adhesive fills the glue injection cavity 5 and the glue injection channel 6. The adhesive is an epoxy resin sealant with excellent adhesion and durability, which can form a strong adhesive layer after curing, effectively enhancing the connection strength between the floor bodies 1. The adhesive filled in the glue injection cavity 5 and the glue injection channel 6 can form a uniform adhesive layer after curing, enhancing the sealing performance of the floor, preventing moisture, dust, etc. from entering the floor interior, and prolonging the service life of the floor. This design can also improve the installation accuracy of the floor, making the floor surface more flat and beautiful, and improving the overall decorative effect. Example 2

[0045] Mold design: design the mold to ensure that the mold can meet the shape and size requirements of the floor connection structure.

[0046] Co-extrusion process: the floor body 1, the first connecting part 2, the second connecting part 3 and the third connecting part 4 are integrally manufactured by the co-extrusion process. The co-extrusion process can ensure the high uniformity of the first connecting part 2, the second connecting part 3 and the third connecting part 4 in material and structure, form an integral whole, and thus significantly improve the stability and reliability of the floor connecting structure. The integrally manufacturing process reduces the assembly link between parts, avoids the problem of loose connection caused by improper assembly or long-term use, and further enhances the firmness of the floor connection.

[0047] Gluing process: after the floor body 1 is butted, the epoxy resin sealant is injected into the gluing cavity 5 through the gluing channel 6, so as to ensure that the adhesive fills the gluing cavity 5 and the gluing channel 6. During the gluing process, the ratio of the depth to the width of the gluing channel 6 and the ratio of the maximum cross-sectional area of the gluing cavity 5 to the cross-sectional area of the gluing channel 6 can effectively control the flow speed and filling effect of the adhesive, so as to ensure that the adhesive can be uniformly filled into the gluing cavity 5, and avoid the problem of too fast or too slow flow of the adhesive caused by improper ratio.

[0048] Curing process: the injected adhesive is cured to form a firm adhesive layer, thereby enhancing the connection strength between the floor bodies 1. Example 3

Example 4

[0054] In this embodiment, the application scene of the floor is as follows:

[0055] Home decoration: the floor connecting structure is suitable for the installation of composite floor in home decoration, which can provide stable connection and ensure that the floor will not loosen or deform during long-term use. The flat floor surface not only looks beautiful, but also can improve the comfort of living environment.

[0056] Commercial places: in commercial places such as shopping malls, offices, etc., the floor connecting structure can ensure the stability and sealing of the floor, preventing the floor from being damaged due to large flow of people. The use of epoxy resin joint sealant can effectively prevent moisture and dust from entering the floor, prolonging the service life of the floor.
