Description

Technical Field

[0001] The invention belongs to the field of couplet making, and in particular relates to a ceramic couplet and a making method thereof. Background Art

[0002] At present, the materials used to make couplets include paper, wood, bamboo, metal, etc. These materials have a common defect: they will fade, deteriorate, and rot over time, affecting their appearance. Especially when used in outdoor scenes such as scenic spots, the above defects will soon occur after being exposed to the sun and rain.

[0003] The antithetical couplets of the prior art are relatively easy to install because the material used is light in weight and can be hung by gluing or hanging rings. Summary of the invention

[0004] In view of the above problems, the present invention aims to provide a couplet that does not fade, deteriorate or rot, and also provides a method for making the couplet.

[0005] The definitions of the terms used in this case are as follows:

[0006] Couplet body: a carrier used to carry works such as text or paintings. In this case, the carrier is fired ceramics.

[0007] Body segment: Made of the same material as the couplet body, it can be considered as the small segment into which the couplet body is divided. At least two body segments can be connected to form a complete couplet body.

[0008] Non-display surface: On the couplet body, at least one surface is used to carry text, paintings and other works, which is called the display surface. On the contrary, the surface that is not used to carry works is called the non-display surface.

[0009] In addition, the directional words such as up and down, as well as the length, width, thickness, etc. of the couplet mentioned in this case are based on the state of the couplet when it is normally hung, which is in line with daily living habits. The directions are determined for the convenience of description and do not constitute a limitation on the structure.

[0010] The technical solution of the present invention to solve the problem is:

[0011] A couplet, comprising:

[0012] A couplet body, the couplet body is made of ceramic material; a blind hole is opened on the non-display surface of the couplet body;

[0013] A supporting member, wherein an adhesive layer is provided between the supporting member and the non-display surface of the couplet body, and the adhesive layer adheres and fixes the supporting member and the couplet body; a through hole is provided on the supporting member at a position corresponding to the blind hole;

[0014] A hanging part, wherein the hanging part is fixedly connected to the supporting member;

[0015] The anchor assembly comprises an anchor rod fixedly arranged in the blind hole and passing through the through hole, and a locking member cooperating with the anchor rod to lock the supporting member and the couplet body.

[0016] In the above scheme, the couplet body is made of ceramic material fired at high temperature. The characteristics of ceramics determine that the works on the couplet display surface will never fade, the couplet is not easy to deteriorate or decay, has a long service life, and its aesthetics remain unchanged throughout its life cycle.

[0017] There are many technical problems to overcome in the firing process of ceramic couplets. For example, the long clay blanks will crack and warp during the high-temperature firing process, and the blanks will shrink unevenly and deform. There are also problems such as uneven heating inside and outside due to the excessive thickness of the clay blanks. It is precisely because of these problems that no one has invented ceramic couplets since the emergence of couplets thousands of years ago.

[0018] After the inventor of this case invented the ceramic couplet, a new problem arose: since ceramic was used as the material of the couplet, it was much heavier than traditional materials and difficult to hang. In response to this further problem, structural designs such as supporting parts and anchoring components were used to improve the safety of hanging.

[0019] Furthermore, the couplet body is formed by splicing at least two body segments, and grooves are provided on the facing end surfaces of two adjacent body segments;

[0020] It also includes a connecting piece, the two ends of which are respectively inserted into the grooves of two adjacent body segments, and the connecting piece is fixedly connected to the inner wall of the groove by an adhesive;

[0021] The facing end surfaces of two adjacent body segments are fixedly connected by an adhesive.

[0022] The above further solution is a solution to reduce production costs, because the length of the couplet is long, the process of making an integrated couplet body is difficult, the yield is slightly low, and the clay blank is difficult to shape and wastes a lot. Therefore, using ceramic fired body segments with small sizes, and splicing multiple body segments into the couplet body, is more conducive to reducing costs and production difficulty.

[0023] Accordingly, in order to solve the above-mentioned problem of difficulty in making couplets, this case also provides a method for making ceramic couplets. The method comprises the following steps:

[0024] A) Firing the ceramic couplet body, and then carving the work on the display surface of the couplet body;

[0025] In this step, a disc-shaped clay blank is fired into ceramics and then cut into the shape of a couplet. The cutting step can be done before or after the carving work.

[0026] C) The hanging part is fixedly connected to the supporting member; the couplet body is bonded to the supporting member with a through hole by an adhesive, and a blind hole is opened on the non-display surface of the couplet body; the timing of the fixed connection between the hanging part and the supporting member can be performed at any time before the couplet body and the supporting member are bonded;

[0027] There are two processes for opening blind holes in this step:

[0028] The first process a) is to open the blind hole before bonding the couplet body to the supporting member. The process is to immerse the couplet body in water, drill the blind hole directly on the non-display surface of the couplet body by underwater drilling, and then bond the non-display surface of the couplet body with the blind hole drilled and the supporting member with the through hole by adhesive, and wait for the adhesive to dry thoroughly.

[0029] The second process b) is to open the blind hole after the couplet body is bonded to the supporting part. The process is to bond the non-display surface of the couplet body to the supporting part with the through hole through an adhesive. After the adhesive is completely dry, a blind hole is drilled directly at the beginning of the through hole with a special drill bit. Coolant must be used for continuous cooling during the drilling process.

[0030] D) Install the anchor assembly. The process is as follows: after the couplet body and the supporting member have been firmly bonded, glue is applied in the blind hole, and then one end of the anchor rod is inserted into the blind hole and the other end of the anchor rod is kept passing through the through hole. After the anchor rod inserted into the blind hole is firmly bonded in the blind hole, the supporting member and the couplet body are fitted and locked by the locking member.

[0031] As mentioned above, during the firing process of ceramic couplets, problems such as cracking and warping of long strips of clay blanks during high-temperature firing will occur, resulting in no one having invented ceramic couplets. In the above step A), using disc-shaped clay blanks to fire into ceramics is one of the important innovations of this case. Since the disc-shaped clay blanks shrink in equal amounts during high-temperature firing, the fired ceramics will not crack or warp, and the yield rate is high.

[0032] How to drill holes is another important innovation of the present invention. For ceramic couplets, it is impossible to drill holes before firing, otherwise the hole diameter will change or the hole will deform due to the shrinkage of the clay during the firing process. Therefore, holes must be drilled after firing into ceramics. However, drilling holes in ceramics is extremely difficult. If holes are drilled directly on the couplet body, it often causes the ceramics to crack. Therefore, a new drilling method is adopted in this case.

[0033] The drilling method of the first process a) of the present invention not only does not cause cracks, but also has good cooling conditions and a longer service life because the drill bit is immersed in water. The second process b) of the present invention has a support member and an adhesive to constrain the couplet body, and the adhesive layer itself has a certain flexibility and a shock-absorbing effect, so that cracks are not easy to appear during the drilling process.

[0034] In a preferred solution, when the couplet body is composed of at least two body segments, after step A) and before step C), the method further includes:

[0035] Step B) splicing the body segments into an integral couplet body, the process includes providing grooves on the facing end faces of each two adjacent body segments, inserting the two ends of the connector into the grooves of the two adjacent body segments respectively, and fixing the connector to the inner wall of the groove by adhesive; then fixing the facing end faces of the adjacent body segments by adhesive, keeping the adhesive seam in place and tightening on the fixture, and waiting for the adhesive to dry.

[0036] In a preferred solution, the locking member in step D) is a nut, the outer diameter of the nut is larger than the diameter of the through hole; the anchor rod is a threaded rod, and the anchor rod and the locking member are threadedly matched to fit and lock the supporting member and the couplet body.

[0037] Furthermore, the thickness of the couplet body is greater than or equal to 2 cm. The ceramic couplet of the present invention is different from other ceramic paintings, tiles and other ceramic plates with a thickness of less than 8 mm. The thickness is not less than 2 cm. One is the requirement of the production process, and the other is that it focuses more on outdoor application scenarios and ensures product strength.

[0038] Furthermore, the weight of the couplet body is greater than or equal to 30 kilograms.

[0039] Preferably, the length of the lower end of the supporting member exceeds the length of the lower end of the couplet body, and / or,

[0040] A rubber pad is arranged at the lower end of the supporting member.

[0041] This preferred solution is to prevent the ceramic couplet body from being damaged after accidentally falling. When falling, the lower end of the supporting member first touches the ground, which plays a certain buffering role. Or the rubber pad plays a buffering role.

[0042] Specifically, the hanging portion is a hanging ring, which is arranged on the upper end of the supporting member.

[0043] Specifically, the connecting member is a metal block and serves to pull the adjacent body segments.

[0044] Preferably, the width of the supporting member is the same as that of the couplet body. Generally, the supporting member can be arranged on the back of the ceramic couplet body, and the two side surfaces and the upper and lower end surfaces of the couplet body do not need to be arranged, and they can be displayed.

[0045] The remarkable effects of the present invention are:

[0046] First, the innovative method of using disc-shaped clay blanks that are fired and then cut has produced a type of ceramic couplet that is not afraid of sun and rain, and whose display surface will never fade. This type of couplet is not easy to deteriorate or decay, has a long service life, and its beauty remains unchanged throughout its life cycle.

[0047] Secondly, in view of the fact that the ceramic couplet is both heavy and thick, a structure and manufacturing method that can improve the safety of hanging is designed. The supporting parts are bonded to the couplet body and locked by anchoring components to form a double fixing structure to ensure that such a heavy ceramic couplet body can be hung.

[0048] Third, in view of the difficulty in drilling holes in ceramics before installing the anchor assembly, which is prone to cracks, the first process a) underwater drilling can avoid cracks, have a high drilling pass rate, and increase the service life of the drill bit. The second process b) drilling method is used, and cracks are not likely to occur during the drilling process. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0057] Example 1

[0058] like Figures 1 to 3 As shown, Figure 1 What is seen is the back side, and the front side is not shown. The front side is the display side carrying the works. A couplet comprises a couplet body 1, a blind hole 2, a supporting member 3, an adhesive layer 4, a hanging part 5, and an anchoring assembly 6.

[0059] The couplet body 1 is made of ceramic material and has a blind hole 2 on the non-display surface of the couplet body 1 .

[0060] An adhesive layer 4 is provided between the supporting member 3 and the non-display surface of the couplet body 1. The adhesive layer 4 adheres and fixes the supporting member 3 to the couplet body 1. A through hole is provided on the supporting member 3 at the position corresponding to the blind hole 2. The material of the supporting member 3 is preferably a stainless steel plate.

[0061] The hanging portion 5 is fixedly connected to the supporting member 3 .

[0062] The anchoring assembly 6 includes an anchoring rod 61 fixedly disposed in the blind hole and passing through the through hole, and a locking member 62 cooperating with the anchoring rod to lock the supporting member 3 and the coupling body 1 .

[0063] This embodiment also provides a method for making ceramic couplets, which includes the following steps:

[0064] A) firing a ceramic couplet body 1, and then carving works on the display surface of the couplet body 1;

[0065] In this step, a disc-shaped clay blank is fired into ceramics and then cut into the shape of a couplet. The cutting step can be done before or after the carving work.

[0066] C) The hanging part 5 is fixedly connected to the supporting member 3; the couplet body 1 is bonded to the supporting member 3 with a through hole by an adhesive, and a blind hole 2 is opened on the non-display surface of the couplet body 1; the above-mentioned fixed connection between the hanging part 5 and the supporting member 3 can be performed at any time before the couplet body 1 and the supporting member 3 are bonded;

[0067] There are two processes for opening blind hole 2 in this step:

[0068] The first process a) is to open the blind hole before bonding the couplet body 1 to the supporting member 3. The process is to immerse the couplet body 1 in water, and use underwater drilling to drill the blind hole 2 directly on the non-display surface of the couplet body 1 with a drill bit, and then bond the non-display surface of the couplet body 1 with the blind hole 2 drilled and the supporting member 3 with the through hole through an adhesive, and wait for the adhesive to dry thoroughly.

[0069] The second process b) is to open the blind hole after the couplet body 1 and the supporting member 3 are bonded together. The process is to bond the non-display surface of the couplet body 1 to the supporting member 3 with the through hole through an adhesive. After the adhesive is completely dry, a blind hole 2 is drilled directly at the beginning of the through hole with a special drill bit. Coolant must be used for continuous cooling during the drilling process.

[0070] D) Install the anchor assembly 6. The process is as follows: after the couplet body 1 and the supporting member 3 have been firmly bonded, glue is applied in the blind hole 2, and then one end of the anchor rod 61 is inserted into the blind hole 2 and the other end of the anchor rod 61 is kept passing through the through hole. After the anchor rod 61 inserted into the blind hole 2 is firmly bonded in the blind hole 2, the supporting member 3 and the couplet body 1 are fit and locked by the locking member 62.

[0071] The locking member 62 in step D) is preferably a nut, the outer diameter of which is larger than the diameter of the through hole. The anchor rod 61 is a threaded rod, and the anchor rod 61 is threadedly matched with the locking member 62 to fit and lock the supporting member 3 and the couplet body 1.

[0072] The above nuts can be flange nuts.

[0073] The couplet body 1 has a thickness of 3-5 cm.

[0074] The couplet body 1 weighs 30-50 jin.

[0075] In order to increase the cushioning and avoid breaking after falling, the length of the lower end of the supporting member 3 exceeds the length of the lower end of the couplet body 1, and / or,

[0076] A rubber pad is arranged at the lower end of the supporting member 3 .

[0077] The hanging portion 5 is a hanging ring, which is arranged on the upper end of the supporting member 3 .

[0078] The width of the supporting member is the same as that of the couplet body 1. That is, the supporting member can be arranged on the back of the ceramic couplet body 1, and the two side surfaces and the upper and lower end surfaces of the couplet body 1 do not need to be arranged, and they are display surfaces that can be displayed.

[0079] Example 2

[0080] The solution of this embodiment is basically the same as that of embodiment 1, except that: Figure 4-5 As shown, the couplet body 1 is formed by splicing at least two body segments 11. The facing end surfaces of two adjacent body segments 11 are each provided with a groove 12. It also includes a connecting member 7, the two ends of which are respectively inserted into the grooves 12 of the two adjacent body segments 11, and the connecting member 7 is fixedly connected to the inner wall of the groove 12 by an adhesive; the facing end surfaces of two adjacent body segments 11 are fixedly connected by an adhesive.

[0081] The processing technology corresponding to the above structural solution is, after step A) of embodiment 1 and before step C), further comprising:

[0082] Step B) splicing the body segments 11 into an integral couplet body 1, the process includes providing grooves 12 on the facing end faces of each two adjacent body segments 11, inserting the two ends of the connecting piece 7 into the grooves 12 of the two adjacent body segments 11 respectively, and fixing the connecting piece 7 to the inner wall of the groove 12 by an adhesive; then fixing the facing end faces of the adjacent body segments 11 by an adhesive, keeping the adhesive seam in place and tightening on the fixture, and waiting for the adhesive to dry.

[0083] The connecting member 7 is a metal block and serves to pull the adjacent body segments.

[0084] Embodiment 2 is a solution to reduce production costs. Because the length of the couplet is long, the process of making an integrated couplet body is difficult, the yield is slightly low, and the clay blank is difficult to shape and wastes a lot. Therefore, using a body segment 11 with a small size fired by ceramics, and splicing multiple body segments 11 into a couplet body 1, is more conducive to reducing costs and production difficulty.

[0085] It should be noted that the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatus.
