Description

Technical Field

[0001] The utility model relates to the technical field of ceramic plates, and particularly relates to a curved ceramic plate. Background Art

[0002] When manufacturing curved ceramic plates in the prior art, generally, flat ceramic plates are subjected to secondary high-temperature treatment to make them thermally bent and softened to obtain a curved shape. This preparation method has a cumbersome process and is time-consuming and laborious. In addition, curved ceramic plates are usually used for exterior walls. To ensure their firm combination with the exterior walls, large-sized curved ceramic plates generally need to be further combined with anchor fittings. However, the existing anchor fittings are usually combined with the curved ceramic plates during the secondary high-temperature treatment, and the combination fastness between the two is not strong enough. Other types of anchor fittings are fixedly connected to the curved ceramic plates through clamping or other connection methods, which have many construction steps and still have the problems of insufficient firm combination between the anchor fittings and the curved ceramic plates and short service life.

[0003] It can be seen that the prior art still needs to be improved and enhanced. Summary of the Utility Model

[0004] In view of the deficiencies of the above prior art, the purpose of the utility model is to provide a curved ceramic plate, aiming to solve the problems of complex manufacturing and construction processes of curved ceramic plates in the prior art and poor firmness during paving.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A curved ceramic plate, comprising a curved plate body integrally extruded and formed and an anchoring component; the anchoring component is arranged on the back side of the curved plate body; the anchoring component includes a plurality of protrusions.

[0007] For the above-mentioned curved ceramic plate, the cross-sectional shape of the protrusion in the vertical direction is an inverted trapezoid, a regular trapezoid, a square or a circle.

[0008] For the above-mentioned curved ceramic plate, the thickness of the curved plate body is 2 mm to 20 mm, and the thickness of the protrusion is 5 mm to 20 mm.

[0009] For the above-mentioned curved ceramic plate, a plurality of the protrusions are arranged in parallel and respectively extend along the length direction of the curved plate body.

[0010] For the above-mentioned curved ceramic plate, a plurality of the protrusions are arranged in a matrix.

[0011] For the above-mentioned curved ceramic plate, at least one layer of ceramic glaze layer is arranged on the exposed surface of the curved plate.

[0012] The described curved ceramic sheet, wherein a high-reflection heat-insulating ceramic glaze layer is provided on the exposed surface of the curved sheet body.

[0013] The described curved ceramic sheet, wherein the cross-sectional shape of the curved sheet body in the vertical direction is arc-shaped or wavy.

[0014] The described curved ceramic sheet, wherein the front surface of the curved sheet body is provided with concave-convex shapes.

[0015] Beneficial effects: The present utility model provides a curved ceramic sheet. The curved sheet body and the anchoring component of the curved ceramic sheet are integrally formed, and there is no connection interface between the two parts, and the overall connection strength is the same. Compared with the combined structure of the ceramic sheet and the anchoring component, the present utility model has stronger firmness. When the curved ceramic sheet is laid, a plurality of protrusions can play an anchoring role with adhesives such as cement or tile adhesive, improving the safety in use. According to the different designed shapes of the protrusions, the curved ceramic sheet can also be constructed by the dry-hanging method, and the construction methods are diversified.

[0024] The present utility model provides a curved ceramic sheet. To make the purpose, technical solution and effects of the present utility model clearer and more definite, the following further describes the present utility model in detail with reference to the drawings and by way of examples.

[0025] In the description of the present utility model, it should be understood that the terms "upper", "lower", "left", "right", "vertical direction", etc. indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, as well as a specific orientation structure and operation. Therefore, it should not be construed as a limitation to the present utility model. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0026] Please refer to Figure 1 , the present utility model provides a curved ceramic sheet, including a curved sheet body 1 formed by integral extrusion and an anchoring component; the anchoring component is arranged on the back side of the curved sheet body 1; the anchoring component includes a plurality of protrusions 2.

[0027] Specifically, the back side refers to the side of the curved ceramic sheet that faces the adhesive and is connected to the adhesive during use.

[0028] By providing the protrusions 2 on the curved ceramic sheet of the present utility model, it can be anchored with cement or tile adhesive during paving. Structurally, an integral forming structure is adopted to ensure the consistent overall connection strength, and it will not have the problem of insufficient bonding strength as in the prior art due to the non-integral forming structure of the anchoring component and the curved sheet body 1. For the product of the anchoring component and the curved sheet body 1 with a non-integral forming structure, the connection part between the anchoring component and the curved sheet body 1 is usually the weakest in connection strength. During long-term use, the curved sheet body 1 is likely to separate from the anchoring component and fall off, and the long-term use safety is not strong. In addition, in terms of preparation and installation, the curved ceramic sheet of the present utility model does not require processing and connecting or on-site assembling the anchoring component and the curved sheet, with high production efficiency and few construction procedures.

[0029] Preferably, the cross-sectional shape of the protrusion 2 in the vertical direction is an inverted trapezoid, a regular trapezoid, a square or a circle.

[0030] In addition to the above figures, the cross-sectional shape of the protrusion 2 can also be other planar figures, such as other polygons.

[0031] Please refer to Figure 1 , wherein, in addition to being directly used for connection with adhesives such as cement or tile adhesive and playing an anchoring role, the protrusion 2 with an inverted trapezoid cross-sectional shape can also be used for dry-hanging construction, and the construction method is more diverse, which can meet different construction requirements.

[0032] Preferably, the thickness of the curved panel body 1 is 2 mm to 20 mm, and the thickness of the protrusion 2 is 5 mm to 20 mm. The thicknesses of the curved panel body 1 and the protrusion 2 should not be too large, otherwise the overall weight will be too large, increasing the load-bearing burden. The thicknesses of the curved panel body 1 and the protrusion 2 should not be too small either, otherwise there will be problems with insufficient structural and connection strength, and it will be difficult to process and form the curved ceramic panel.

[0033] Preferably, a plurality of the protrusions 2 are arranged in parallel and extend along the length direction of the curved panel body 1 respectively. In this embodiment, the length of the protrusion 2 is not greater than the length of the curved panel body 1.

[0034] Preferably, a plurality of the protrusions 2 are arranged in a matrix. Compared with the previous embodiment, the protrusions 2 distributed in a matrix can provide more anchoring points on the back of the limited curved panel body 1.

[0035] Preferably, the anchoring assembly includes multiple layers of groups of protrusions 2, and each layer of the group of protrusions 2 includes a plurality of protrusions 2, and the plurality of protrusions 2 in different layers are staggered. The staggered protrusions 2 can provide more anchoring points in the horizontal and vertical directions.

[0036] Preferably, at least one layer of ceramic glaze layer 3 is provided on the exposed surface of the curved panel. The ceramic glaze layer 3 can be a glaze layer or a dry granule glaze layer. By providing the ceramic glaze layer 3, in addition to increasing the aesthetic degree, it can also increase the surface hardness and wear resistance of the curved ceramic panel.

[0037] In a preferred embodiment, a layer of ceramic glaze layer 3 is provided on the exposed surface of the curved panel, and the ceramic glaze layer 3 is a high-reflection heat-insulating ceramic glaze layer 3. The exposed surface refers to the exposed surface during use. The high-reflection heat-insulating ceramic glaze layer 3 can reflect sunlight in the full wavelength band better, so as to achieve good heat insulation and effectively delay the aging of the adhesive. The curved ceramic panel provided by the present utility model is mainly used as a wall decoration material. In summer, when the ceramic panel is used as an exterior wall tile, adhesives such as cement and tile adhesive and conventional tiles will have a very high temperature after long-term exposure to the sun, which will accelerate the aging of the adhesive, and it is easy to loosen and fall off after long-term use. By providing the high-reflection heat-insulating ceramic glaze layer 3, the temperature of the curved ceramic panel after exposure can be reduced, and the connection fastness between the curved ceramic panel and the adhesive after long-term use can be effectively improved.

[0038] Preferably, the cross-sectional shape of the curved panel body 1 in the vertical direction is arc-shaped or wavy.

[0039] Please refer to Figure 7 In a preferred embodiment, the front surface of the curved panel body 1 (corresponding to Figure 7The bottom surface of the curved panel material body is provided with concave and convex shapes to increase the aesthetic degree of the curved surface ceramic plate.

[0040] The curved surface ceramic plate with the cross-sectional shape of the curved panel material body 1 being arc-shaped can be used for laying columns. By combining multiple arc-shaped curved surface ceramic plates, the surrounding paving of the columns can be completed.

[0041] The curved surface ceramic plate with the cross-sectional shape of the curved panel material body 1 being wavy can be used for laying tile surfaces, wall surfaces, etc.
