Description

Technical Field

[0001] This invention relates to the field of ceramic tile technology, specifically to ceramic tiles with a textured back. Background Technology

[0002] In the process of tile laying, the back of traditional tiles is mostly flat or has a simple striped structure, which limits the bonding area with the adhesive material. This can easily lead to problems such as weak adhesion, hollowing, or even detachment, especially in humid environments or under long-term stress. In addition, if the drainage on the back of the tile is not good, water accumulation may affect the stability of the adhesive layer and cause the substrate to become damp. Therefore, how to design a back structure that can improve the bonding strength between the tile and the adhesive material and improve the drainage effect has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0003] The purpose of this invention is to provide a ceramic tile with a concave-convex structure on the back to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a ceramic tile with a concave-convex structure on the back, comprising a ceramic tile body, wherein the ceramic tile body is defined to have a longitudinal direction along the length direction and a transverse direction perpendicular to it, and the back of the ceramic tile body is provided with a concave-convex groove structure; the concave-convex groove structure includes a plurality of first oblique guide grooves that are inclined relative to the central axis of the ceramic tile body and a plurality of second oblique guide grooves that are inclined relative to the central axis of the ceramic tile body. A first rhomboid protrusion is formed between two adjacent first inclined guide channels and two adjacent second inclined guide channels; The surface of the ceramic tile body has a curved structure, and the height of the curvature is 3-50mm. The tile body has a tenon structure and a mortise structure extending longitudinally on both sides of its horizontal axis. One longitudinal side of the tile body has an arc-shaped curved surface, and the other longitudinal side of the tile body has an arc-shaped covering block for covering adjacent longitudinal tiles. The arc-shaped covering block extends out of the tile body, and the thickness of the tile body gradually increases from the arc-shaped curved surface towards the arc-shaped covering block. When two tiles are horizontally spliced ​​together, the tenon structure and the mortise structure form a snap-fit ​​structure to achieve horizontal self-locking.

[0005] Furthermore: the width of the vertical guide channel is 1.5-3mm, the depth is 0.8-1.5mm, and the height of the first anti-slip protrusion is 0.3-0.6mm.

[0006] Furthermore: the groove structure includes several vertical guide grooves formed along the length of the tile body, a first plane is formed between adjacent vertical guide grooves, and several first anti-slip protrusions are provided on the first plane.

[0007] Furthermore: the width of the first and second inclined guide channels is 1.5-3mm, the depth is 0.8-1.5mm, and the height of the first rhomboid protrusion is 0.3-0.6mm.

[0008] Furthermore: the groove structure includes several first oblique ribs that are inclined relative to the central axis of the tile body and several second oblique ribs that are inclined relative to the central axis of the tile body; A second rhomboid surface is formed between two adjacent first oblique ribs and two adjacent second oblique ribs, and the distance between the second rhomboid surface and the top surface of the first oblique rib and the second oblique rib is 0.3-0.6mm.

[0009] Furthermore: the groove structure includes a vertical main flow channel that coincides with the central axis of the ceramic tile body and several third oblique flow channels symmetrically arranged on both sides of the vertical main flow channel; Several vertical drainage channels are provided on the back of the ceramic tile. The width ratio of the vertical main guide channel, the third inclined guide channel, and several vertical sub-guide channels is 1:0.25-0.35:0.1-0.15.

[0010] Furthermore: the tenon structure includes a main tenon body and a limiting shoulder, and the main tenon body has a first stepped surface on its side; the mortise structure includes a mortise extending outward from one side of the tile body, and the bottom of the mortise has a main receiving groove adapted to the first stepped surface, and a limiting step is provided between the side of the tile body and the mortise for horizontal contact with the limiting shoulder.

[0011] Furthermore: a second stepped surface is provided between the limiting shoulder and the lateral side of the tile body; the surface of the first stepped surface has a downwardly recessed groove.

[0012] Compared with the prior art, the beneficial effects of the present invention are: The ceramic tile with a concave-convex structure on the back of the present invention effectively increases the contact area and mechanical interlocking force with the adhesive material by setting a concave-convex groove structure on the back of the tile body, significantly improving the bonding firmness of the tile after installation and reducing the risk of hollowing and falling off. Among them, the groove structure with different designs, such as the vertical guide groove, the first inclined guide groove and the second inclined guide groove, the first inclined rib and the second inclined rib, and the vertical main guide groove and the third inclined guide groove, can quickly drain the water accumulated on the back of the tile according to the actual use scenario, avoiding the adverse effect of water accumulation on the stability of the adhesive layer.

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0016] refer to Figures 1 to 4 A type of ceramic tile with a concave-convex structure on its back is defined as follows: the tile body 1 has a longitudinal direction along its length and a transverse direction perpendicular to it; the back of the tile body 1 is provided with a concave-convex groove structure; the concave-convex groove structure includes a plurality of first oblique guide grooves 201 and a plurality of second oblique guide grooves 202 that are obliquely distributed relative to the central axis of the tile body 1; a first rhomboid protrusion 203 is formed between two adjacent first oblique guide grooves 201 and two adjacent second oblique guide grooves 202; the surface of the tile body 1 is a curved surface structure with a height of 30mm. The width of the first inclined guide groove 201 and the second inclined guide groove 202 is 2mm, the depth of the groove is 1mm, and the height of the first rhomboid protrusion 203 is 0.4mm.

[0017] The tile body 1 has a tenon structure and a mortise structure extending longitudinally on its lateral sides. The tenon structure includes a main tenon 603 and a limiting shoulder 701. The main tenon 603 has a first step surface 604 on its side. The mortise structure includes a mortise 605 extending outward from one lateral side of the tile body. The bottom of the mortise 605 has a main receiving groove 606 that matches the first step surface 604. A limiting step 3 is provided between the lateral side of the tile body 1 and the mortise 605 for horizontally abutting against the limiting shoulder 701.

[0018] A second step surface 702 is provided between the limiting shoulder 701 and the lateral side of the tile body; the surface of the first step surface 604 has a downwardly recessed groove 2.

[0019] The tile body 1 has an arc-shaped curved surface 602 formed on one longitudinal side, and an arc-shaped covering block 601 for covering adjacent longitudinal tiles is formed on the other longitudinal side of the tile body 1. The arc-shaped covering block 601 extends out of the tile body 1, and the thickness of the tile body 1 gradually increases from the arc-shaped curved surface towards the arc-shaped covering block 601. An arc-shaped water-blocking groove 4 is provided on the back of the arc-shaped covering block 601. When two tiles are horizontally spliced ​​together, a snap-fit ​​structure is formed between the tenon structure and the mortise structure to achieve horizontal self-locking.

[0020] In this embodiment, the groove structure includes several first oblique guide grooves 201 and several second oblique guide grooves 202 that are obliquely distributed relative to the central axis of the tile body 1. The first oblique guide grooves 201 and the second oblique guide grooves 202 are inclined in opposite directions, forming a cross-grid groove. The grid grooves and the adhesive form a three-dimensional interlocking structure, which greatly enhances the bonding strength and prevents large-sized tiles from hollowing or falling off due to uneven stress. A first rhomboid surface is formed between two adjacent first oblique guide grooves 201 and two adjacent second oblique guide grooves 202. Each rhomboid surface is uniformly provided with at least one... The second anti-slip protrusion 203 is missing. The width of the first inclined guide channel 201 and the second inclined guide channel 202 is 2.5mm, the depth is 1.0mm, the height of the second anti-slip protrusion 203 is 0.5mm, and the second anti-slip protrusion 203 is in the shape of a square pyramid or cylinder with a base side length of 1.0mm. In actual laying, when there is water accumulation on the back of the tile, the cross-distributed first inclined guide channel 201 and second inclined guide channel 202 can guide the water in multiple directions, avoiding the problem of poor drainage in one direction. This embodiment is especially suitable for scenarios with a certain slope of the ground and large-sized tiles, where water can flow quickly to lower areas along the inclined channels. Example 2

[0021] refer to Figure 5 and Figure 6 A type of ceramic tile with a textured back surface, the textured structure including a plurality of vertical guide grooves 101 formed along the length of the tile body 1, a first plane forming between adjacent vertical guide grooves 101, and a plurality of first anti-slip protrusions 102 provided on the first plane. The vertical guide grooves 101 have a groove width of 2 mm and a groove depth of 1.2 mm. The first anti-slip protrusions 102 have a height of 0.4 mm and are in the shape of a square pyramid or cylinder with a diameter of 0.8 mm. The first anti-slip protrusions 102 are arranged in a matrix. The arrangement allows for quick drainage of water along the length of the vertical guide channel 101 when water accumulates on the back of the tile body 1 during installation. Meanwhile, the first anti-slip protrusion 102 on the first plane can be embedded in the adhesive material to increase mechanical interlocking force and effectively prevent the tile from slipping during the curing process of the adhesive layer. At the same time, the tenon structure and the mortise structure of adjacent tiles form a snap-lock structure to achieve lateral self-locking, further improving the connection stability between tiles and avoiding the edge warping problem that is prone to occur with traditional flat back tiles.

[0022] This embodiment can be applied to wall tiling. The vertical guide channel 101 conforms to the principle of gravity drainage, which can more effectively guide any water that may seep in to the bottom of the tile for drainage, avoiding horizontal seepage inside the wall. An anti-slip protrusion 102 can provide strong resistance to vertical slippage of the tile body 1 before the adhesive cures, ensuring the accuracy of the tiling position. Example 3

[0023] Unlike Embodiment 1, it has a convex-groove structure, such as Figure 7 As shown, the groove structure in this embodiment includes several first oblique ribs 301 and several second oblique ribs 302 that are obliquely distributed relative to the central axis of the tile body 1. The first oblique ribs 301 and the second oblique ribs 302 are inclined in opposite directions, forming a cross-grid-like protrusion structure. A second rhomboid surface is formed between two adjacent first oblique ribs 301 and two adjacent second oblique ribs 302. The distance between the second rhomboid surface and the top surface of the first oblique ribs 301 and the second oblique ribs 302 is 0.5 mm. The cross-section of the first oblique ribs 301 and the second oblique ribs 302 is an isosceles trapezoid with an upper base width of 1.2 mm, a lower base width of 2.0 mm, and a height of 0.5 mm.

[0024] During the installation process, these intersecting diagonal ribs can be directly embedded in the adhesive material, forming a support structure similar to a "skeleton." This significantly increases the contact area and mechanical interlocking force between the back of the tile and the adhesive material. When the adhesive material fills the second rhomboid surface and wraps around the diagonal ribs, the cured adhesive layer and the diagonal ribs form a strong whole, effectively resisting the shrinkage and expansion stress of the tile caused by temperature changes or external forces, reducing the risk of cracking. The second rhomboid surface provides ample filling space for the adhesive material, ensuring a uniform thickness of the adhesive layer and avoiding uneven stress caused by local voids.

[0025] This embodiment is particularly suitable for heavy-duty floors that require high bonding strength, such as shopping malls and garages. The grid structure of the diagonal ribs can better distribute the floor load and improve the overall load-bearing capacity of the tiles. Example 4

[0026] The difference from Embodiment 1 is the convex-groove structure, such as Figure 8As shown, in this embodiment, the convex-concave groove structure includes a vertical main flow channel 401 coinciding with the central axis of the tile body 1 and several third oblique flow channels 402 symmetrically arranged on both sides of the vertical main flow channel 401. Several vertical sub-flow channels 403 are provided on the back of the tile body 1. The width of the vertical main flow channel 401 is 3mm, the width of the third oblique flow channel 402 is 1mm, and the width of the vertical sub-flow channels 403 is 0.4mm. The width ratio of the three is 1:0.33:0.13. The depth of the vertical main flow channel 401 is 1.5mm, and the depths of the third oblique flow channel 402 and the vertical sub-flow channels 403 are both 1.0mm. The angle between the three inclined drainage channels 402 and the central axis of the tile body 1 is 60 degrees, and they slope downward from the vertical main drainage channel 401 towards the edge of the tile body 1. The vertical sub-drainage channels 403 are evenly distributed between the adjacent third inclined drainage channels 402. During installation, if there is water accumulation on the back of the tile, the third inclined drainage channels 402 distributed on both sides will first guide the water obliquely to the central vertical main drainage channel 401, while the vertical sub-drainage channels 403 can collect the local water accumulation in the diamond-shaped area and flow into the third inclined drainage channel 402, and finally be quickly discharged through the vertical main drainage channel 401. This graded drainage design greatly improves the targeting and efficiency of drainage.

[0027] Meanwhile, the wider vertical main drainage channel 401 can accommodate more adhesive material, increasing the bonding area between the tile and the substrate, while the narrower third inclined drainage channel 402 and vertical branch drainage channel 403 ensure the flatness of the back of the tile without affecting drainage, allowing the adhesive material to be filled evenly and avoiding the problem of uneven adhesive layer thickness caused by excessively deep or wide grooves.

[0028] This embodiment is very suitable for scenarios where the flatness of the ground is required and there may be a lot of water accumulation, such as bathrooms and kitchens. The graded drainage structure can quickly drain the water that seeps in during construction or use, protecting the base layer from moisture. At the same time, the combination of drainage channels of various widths also enhances the mechanical interlocking effect between the back of the tile and the adhesive material, improving the overall paving firmness.

[0029] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended embodiments and their equivalents.
