Abstract
Description
Technical Field
[0001] The utility model relates to a ceramic tile with an anti-falling function, in particular to an anti-falling ceramic tile which can form a rigid mortise and tenon structure with an adhesive. Background Art
[0002] Ceramic tiles are made of raw materials such as clay, quartz sand, etc., and are made of acid- and alkali-resistant porcelain or stone building or decorative materials through the process of grinding, mixing, pressing, glazing, and sintering. When used, the tiles are laid on the wall or floor with adhesives or cement mortar. The surface friction of the tiles and the adhesive or cement mortar are simply combined, and the bonding force between them is small, and the tiles are easy to fall off. In order to increase the bonding area, various patterns are arranged on the back of the tiles. Most of the existing backs of tiles are checkered patterns, curved broom patterns, random patterns, convex dot patterns, etc. Traditional ceramic tiles tend to fall off after a certain period of time after being laid. After excluding external factors such as substandard auxiliary materials, low cement paste grade, expired tile adhesive, and inferior backing glue, the main reasons are: the existing convex and concave patterns are only subjected to frontal force during laying, and there is no lateral anti-falling force structure, which leads to insufficient lateral force and easy falling off after being combined with the adhesive used for construction; and there is inconsistent shrinkage force during demolding, which can easily lead to warping of the tiles due to shrinkage stress over time, causing the tiles to fall off.
[0003] In order to solve the above technical problems, a Chinese utility model patent with application number CN201621059745.6 and authorization announcement number CN206408866U discloses an anti-falling tile, including a glazed surface and a paving surface, wherein the paving surface has multiple grooves, the grooves are trapezoidal, the side length of the lower bottom surface of the trapezoidal body is twice the side length of the upper bottom surface, the upper bottom surface and the lower bottom surface are both square, the height of the trapezoidal body is 1 / 2 of the thickness of the anti-falling tile, the anti-falling tile is provided with a wire mesh parallel to the paving surface, the wire mesh is arranged at 1 / 2 of the height of the groove, the distance between two adjacent steel wires is 0.5~1 cm, the mesh of the wire mesh is diamond-shaped, and the diameter of the steel wire is 0.05 cm; the grooves are arranged in multiple herringbone shapes. The utility model has grooves on the paving surface to increase the friction between the mortar and the tiles. At the same time, the grooves are arranged in a trapezoidal shape, and a steel mesh parallel to the paving surface is arranged at half the height of the grooves, which can significantly increase the bonding force between the mortar and the tiles, making it difficult for the tiles to fall off. The grooves are in a herringbone shape, which makes the structure between the tiles and the mortar stable, and significantly reduces the falling of the tiles.
[0004] However, the anti-falling ceramic tiles disclosed in the above utility model patent also have the following technical problems: (1) The groove is set in a trapezoidal structure, which makes it difficult to demold the ceramic tile blank due to the trapezoidal structure in which the outer opening is smaller than the inner opening when pressing the ceramic tile blank, and cannot be mass-produced through mechanization; (2) The problem of inconsistent shrinkage force during demolding after pressing and forming is not solved, which can easily cause the ceramic tile to warp due to shrinkage stress over time, causing the ceramic tile to fall off. Utility Model Content
[0005] In order to solve the above-mentioned defects of the existing anti-falling ceramic tile which can form a rigid mortise and tenon structure with an adhesive, the utility model provides an anti-falling ceramic tile which can form a rigid mortise and tenon structure with an adhesive.
[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0007] An anti-falling ceramic tile that can form a rigid mortise and tenon structure with an adhesive, comprising a plurality of concave-convex back patterns distributed on the back of the ceramic tile; characterized in that: the concave-convex back patterns are provided with dovetail grooves with barbs; the concave-convex back patterns on the back of the ceramic tile are divided into two left and right areas, the barbs of the dovetail grooves of the concave-convex back patterns on the left side of the back of the ceramic tile face the left, and the barbs of the dovetail grooves of the concave-convex back patterns on the right side of the back of the ceramic tile face the right. This situation is applicable to ceramic tiles that are laid flat, and when the ceramic tiles are laid, the adhesive used in the construction forms a rigid mortise and tenon structure with the dovetail grooves of the ceramic tiles after hardening. Since the barbs of the dovetail grooves of the concave-convex back patterns on the left and right sides of the back of the ceramic tile face opposite directions, forces are applied in different directions, thereby ensuring uniform and balanced forces on the ceramic tile in the left and right directions, and avoiding the destruction of the firmness of the ceramic tile's adhesion due to uneven forces on the ceramic tile in the left and right directions.
[0008] Alternatively, the concave-convex back pattern on the back of the tile is divided into two upper and lower areas, the barbs of the dovetail groove of the concave-convex back pattern on the upper side of the back of the tile face upward, and the barbs of the dovetail groove of the concave-convex back pattern on the lower side of the back of the tile face downward. This situation is suitable for tiles paved on walls. When the tiles are paved, the adhesive used in the construction forms a rigid mortise and tenon structure with the dovetail groove of the tile after hardening. Since the barbs of the dovetail groove of the concave-convex back pattern on the upper and lower sides of the back of the tile face opposite directions, forces are formed in different directions, ensuring uniform balance of forces in the upper and lower directions of the tile, and avoiding damage to the firmness of the tile's adhesion due to uneven forces in the upper and lower directions.
[0009] Alternatively, the concave-convex back pattern on the back of the tile is divided into four regions: up, down, left, and right. The barbs of the dovetail grooves of the concave-convex back pattern on the upper side of the back of the tile face upward, and the barbs of the dovetail grooves of the concave-convex back pattern on the lower side of the back of the tile face downward; the barbs of the dovetail grooves of the concave-convex back pattern on the left side of the back of the tile face left, and the barbs of the dovetail grooves of the concave-convex back pattern on the right side of the back of the tile face right. This situation is also applicable to tiles paved on a flat surface or a wall. When the tiles are paved, the adhesive used in the construction forms a rigid mortise and tenon structure with the dovetail grooves of the tiles after hardening. Since the barbs of the dovetail grooves of the concave-convex back pattern on the four sides of the back of the tile face in opposite directions, forces are formed in four different directions, ensuring uniform and balanced forces in the four directions of the tiles, and avoiding the destruction of the firmness of the tiles due to uneven forces in the four directions.
[0010] Furthermore, the concave-convex back pattern is a honeycomb structure formed by arrangement of hexagonal ribs.
[0011] Furthermore, the center points of any three adjacent hexagonal ribs are connected to form an equilateral triangle, and the distance between the center points of any adjacent hexagonal ribs is 16 mm to 23 mm.
[0012] Furthermore, the width of each side of the hexagonal rib is 2mm~4mm; the hexagonal rib is provided with an approximately circular outer opening with a diameter of 6mm~10mm; the depth from the outer opening to the deepest point inside the hexagonal rib is 1.5mm~2.3mm. The hexagonal rib is used to prevent excessive magnesium and aluminum powder on the surface from affecting the appearance when passing through the roller bar, with a width of 2~4mm and a depth of 0.1~0.5mm as a compensation for shrinkage adjustment.
[0013] Furthermore, the dovetail groove of the hexagonal rib is arranged on the inner wall of one side of the hexagonal rib or one side and its adjacent side; the horizontal projection width of the barb of the dovetail groove is 0.2mm-0.4mm, and the closer to the center of the tile, the smaller the horizontal projection width of the barb of the dovetail groove is. This solves the problem of inconsistent shrinkage force during demoulding, which easily causes the tile to warp due to shrinkage stress over time, causing the tile to fall off.
[0014] Furthermore, the hexagonal ribs are used as anti-falling points of the tiles, and the density of the anti-falling points is 3000 to 4000 per square meter.
[0015] As another solution, the concave-convex back pattern is a quadrilateral or diamond structure.
[0016] As another solution, the concave-convex back pattern is a pattern formed by a mixed arrangement of multiple patterns or a pattern formed by an arrangement of specific patterns.
[0017] The principle of anti-dropping tiles that can form a rigid tenon-mortise structure with adhesives: the tiles form a dovetail groove structure with a hook when they are pressed; and the adhesive is semi-fluid during the tile laying construction, which can penetrate and fill the hook groove; therefore, after the adhesive hardens, it forms a rigid tenon-mortise structure with the tiles, greatly improving the tensile strength and durability of the tiles. Applicable categories include antique tiles, polished tiles, glazed tiles, floor tiles, mid-plates, tiles, exterior wall tiles, paving stones and other full range of dry pressed tiles.
[0018] It can be seen from the above that compared with the prior art, the utility model has the following advantages: scientific structure and reasonable design. Since the back pattern formed during the production of the ceramic tile has a dovetail groove structure in the shape of a barb, when the ceramic tile is laid, the adhesive used in the construction forms a rigid mortise and tenon structure with the dovetail groove of the ceramic tile after hardening, and the physical structural force replaces the chemical bonding force, and the durability of the tensile strength and bonding force of the ceramic tile are greatly improved, thereby completely solving the problem of ceramic tile falling off. The back pattern has a dovetail groove structure in the shape of a barb. When pressing the ceramic tile blank, the demolding is relatively close to the traditional technology, and can be mass-produced by mechanization; technical measures such as adjusting shrinkage compensation are adopted to solve the problem of inconsistent shrinkage force during demolding during pressing and forming, and to avoid the ceramic tile falling off due to the warping phenomenon caused by shrinkage stress over a long period of time.

[0025] The present invention and its beneficial technical effects are further described in detail below in conjunction with the accompanying drawings and preferred embodiments.
[0026] Example 1: See Figure 1~Figure 3The utility model preferably implements an anti-dropping tile that can form a rigid tenon-mortise structure with an adhesive, which includes a plurality of concave-convex back patterns 1 distributed on the back of the tile; the concave-convex back patterns 1 are provided with dovetail grooves 2 with barbs 3; the concave-convex back patterns 1 on the back of the tile are divided into two left and right areas, the barbs 3 of the dovetail grooves 2 of the concave-convex back patterns 1 on the left side of the back of the tile face the left side, and the barbs 3 of the dovetail grooves 2 of the concave-convex back patterns 1 on the right side of the back of the tile face the right side. This situation is suitable for flat-laid tiles. When the tiles are laid, the adhesive 6 used in the construction forms a rigid tenon-mortise structure with the dovetail grooves 2 of the tiles after hardening. Since the barbs 3 of the dovetail grooves 2 of the concave-convex back patterns 1 on the left and right sides of the back of the tile face oppositely, forces in different directions are formed, ensuring uniform and balanced forces in the left and right directions of the tiles, and avoiding the destruction of the firmness of the adhesion of the tiles due to uneven forces in the left and right directions.
[0027] Preferably, the concave-convex back pattern 1 is a honeycomb structure formed by hexagonal ribs 4 arranged in a row.
[0028] Preferably, the center points of any three adjacent hexagonal ribs 4 are connected in an equilateral triangle, and the distance between the center points of any adjacent hexagonal ribs 4 is 16 mm to 23 mm. That is, the side length of the equilateral triangle is 16 mm to 23 mm. For tiles of different specifications, the distance between the center points of the three hexagonal ribs 4 can be determined according to actual needs. Generally, the larger the specification, the longer the distance between the center points of the three hexagonal ribs 4.
[0029] Preferably, the width of each side of the hexagonal rib 4 is 2mm~4mm; the hexagonal rib 4 is provided with an approximately circular outer opening with a diameter of 6mm~10mm; the depth from the outer opening to the deepest point inside the hexagonal rib 4 is 1.5mm~2.3mm. In addition to increasing the stress dispersion of the tile, the design of the hexagonal rib 4 is also aimed at preventing excessive magnesium and aluminum powder on the surface of the roller rod from affecting the appearance when the roller rod is fired. The width of the hexagonal rib 4 is between 2mm~4mm, and the depth is between 0.1mm~0.5mm, which is conducive to adjusting the shrinkage compensation of the blank after pressing and demolding.
[0030] See also Figure 5 Preferably, the dovetail groove 2 of the hexagonal rib 4 is arranged on the inner wall of one side of the hexagonal rib 4 or one side and its adjacent side; the horizontal projection width of the barb 3 of the dovetail groove 2 is 0.2mm-0.4mm, and the horizontal projection width of the barb 3 of the dovetail groove 2 is smaller as it is closer to the center of the tile. The horizontal projection width of the barb 3 is smaller as it is closer to the center, which is conducive to solving the limitation of the expansion off-edge effect, making its stress evenly distributed, and preventing the edge from falling off after a long time.
[0031] Preferably, the hexagonal ribs 4 are used as the anti-dropping points of the tiles, and the density of the anti-dropping points is 3000 to 4000 per square meter. For tiles of different specifications, the corresponding anti-dropping point density is preferably: 4062 per square meter for 400*800 tiles; 650 per square meter for 300*600 tiles; 1300 per square meter for 400*800 tiles; 1400 per square meter for 600*600 tiles; and 2600 per square meter for 800*800 tiles.
[0032] During standard paving, the adhesive 6 forms a rigid mortise and tenon structure with the dovetail groove 2 of the tile after hardening. The tensile strength of the tile can reach 1.2Mpa after 28 days of aging when only 1:1 cement mortar is used for paving, which is three times the national standard of 0.4Mpa; the tensile strength of the tile adhesive is also significantly improved. At the same time, the construction fault tolerance rate is improved. Since the structural prestress of the tile plays a major role in bearing force after paving, the rigid mortise and tenon structure also improves the durability of the bonding force.
[0033] Example 2: See Figure 1~Figure 3 This embodiment is basically the same as the embodiment 1, except that the concave-convex back pattern 1 on the back of the tile is divided into two upper and lower regions, the barbs 3 of the dovetail groove 2 of the concave-convex back pattern 1 on the upper side of the back of the tile face upward, and the barbs 3 of the dovetail groove 2 of the concave-convex back pattern 1 on the lower side of the back of the tile face downward. This situation is suitable for tiles paved on walls. When the tiles are paved, the adhesive 6 used in the construction forms a rigid mortise and tenon structure with the dovetail groove 2 of the tile after hardening. Since the barbs 3 of the dovetail groove 2 of the concave-convex back pattern 1 on the upper and lower sides of the back of the tile face oppositely, forces in different directions are formed, ensuring uniform balance of forces in the upper and lower directions of the tile, and avoiding damage to the firmness of the tile's pasting due to uneven forces in the upper and lower directions.
[0034] Example 3: See Figure 1~Figure 2 and Figure 4 This embodiment is basically the same as the embodiment 1, except that the concave-convex back pattern 1 on the back of the tile is divided into four regions: up, down, left, and right. The barbs 3 of the dovetail groove 2 of the concave-convex back pattern 1 on the upper side of the back of the tile face upward, and the barbs 3 of the dovetail groove 2 of the concave-convex back pattern 1 on the lower side of the back of the tile face downward; the barbs 3 of the dovetail groove 2 of the concave-convex back pattern 1 on the left side of the back of the tile face left, and the barbs 3 of the dovetail groove 2 of the concave-convex back pattern 1 on the right side of the back of the tile face right. This situation is also applicable to tiles paved on a plane or a wall. When the tiles are paved, the adhesive 6 used in the construction forms a rigid mortise and tenon structure with the dovetail groove 2 of the tile after hardening. Since the barbs 3 of the dovetail groove 2 of the concave-convex back pattern 1 on the four sides of the back of the tile face in opposite directions, forces in four different directions are formed, ensuring uniform and balanced forces in the four directions of the tile, and avoiding the destruction of the firmness of the adhesion of the tile due to uneven forces in the four directions of the tile.
[0035] In addition, the anti-falling ceramic tile 5 can also adopt other different graphics and patterns according to actual needs, such as the concave-convex back pattern 1 is a quadrilateral or diamond structure; or the concave-convex back pattern 1 is a pattern of mixed arrangement of multiple graphics or a pattern of specific graphics.
[0036] The utility model preferably implements a method for producing anti-falling ceramic tiles that can form a rigid mortise and tenon structure with an adhesive as follows: Since the main process of ceramic tile production is to grind clay into powder, then press it into shape under high pressure and then fire it at high temperature, the shape of the concave and convex back pattern 1 on the back of the ceramic tile is formed during the pressing process, and only the structural shape of the back pattern mold needs to be changed. During mass production, the existing production line can be applied by changing the mold structure, and other parameters remain basically unchanged. As long as the key technology that can satisfy both the formation of the dovetail groove 2 and smooth demolding is to appropriately design the mold so that the brick blank expands due to stress release when the pressed brick blank is demolded, and the barb 3 of the dovetail groove 2 is naturally generated. For other undisclosed process technologies, conventional production process technologies can be used.
[0037] In the above description, the contents that are conventionally used in the prior art, such as structure and process, are not described in detail in order to save space. The processing technology and parts not disclosed in the utility model can be processed according to the conventional technology of the prior art.
[0038] The above description and specific embodiments do not constitute any limitation to the present invention. The present invention is not limited to the specific implementation methods disclosed and described above. Some modifications and variations of the present invention should also fall within the protection scope of the claims of the present invention.
